Background

With the wide application of various sensors, users pay more and more attention to the accuracy of sensor detection.

In order to reduce the influence of the rise of the ambient temperature on the detection of the sensor, the accuracy of the target parameter influenced by the ambient temperature in the sensor can be improved by a temperature compensation method. In the temperature compensation method in the prior art, a fixed temperature compensation coefficient value is mainly adopted to adjust a target parameter of a sensor.

However, the temperature of the environment where the sensor is located in an actual scene is changed, and therefore, the problem of over-compensation or under-compensation is easily caused when the fixed temperature compensation coefficient value obtained by fitting in the single working mode is used for temperature compensation, so that the target parameter of the sensor cannot be accurately adjusted, and the accuracy of temperature compensation is reduced.

Detailed Description

The technical solutions in the embodiments of the present application will be described clearly below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments that can be derived by one of ordinary skill in the art from the embodiments given herein are intended to be within the scope of the present disclosure.

The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.

The temperature compensation method, the temperature compensation device, the electronic device, and the storage medium according to the embodiments of the present application are described in detail below with reference to the accompanying drawings.

In order to reduce the influence of the increase of the ambient temperature on the target parameter value in the sensor and improve the detection accuracy of the sensor, the target parameter value of the sensor is usually adjusted by using a fixed temperature compensation coefficient value. However, the temperature of the environment in which the sensor is located in an actual scene varies. Therefore, the compensation result obtained by performing temperature compensation on the fixed temperature compensation coefficient value obtained by fitting in the single working mode is not accurate enough, and the target parameter value of the sensor cannot be accurately adjusted.

For example, taking a Specific Absorption Rate (SAR) sensor as an example, as the overall space of the electronic device is designed to be more compact, the SAR sensor and the antenna are closer to the power amplifier and the power management integrated circuit. Because the heat dissipation is relatively poor, and the ambient temperature is higher and higher, the SAR sensor is constantly influenced by the rise of the detected ambient temperature. Specifically, the change of the ambient temperature may affect the dielectric constant of the measurement path, so that the SAR sensor generates temperature drift, and if the temperature drift effect is on the same order of magnitude as the expected user effect, a false release or false trigger problem may be generated, wherein the release may be, for example, releasing the control process of the device transceiving power, and the trigger may be, for example, triggering the control process of the device transceiving power.

In order to reduce the influence of the increase of the ambient temperature on the detection path of the SAR sensor, as shown in fig. 1, a software measure of the conventional scheme is to add a reference channel 120 on the basis of the detection channel 110. The reference channel 120 and the detection channel 110 are pseudo-differentially routed in parallel for compensation of the temperature rise environment, and the compensation formula is as follows:

Useful(n)-Useful(0)＝REFCOEF*[Reference(n)-Reference(0)]

wherein, Useful (n) is a real-time value of the detection channel, Useful (0) is a detection value during the calibration of the detection channel, Reference (n) is a real-time value of the Reference channel, Reference (0) is a detection value during the calibration of the Reference channel, and refcoff is a temperature compensation coefficient.

Since the reference channel extends only to the end of the main board, and is sensitive to environmental drift and insensitive to proximity detection, as shown in fig. 2, the detection channel and the reference channel have very similar drift, and the temperature drift of the value detected by the detection channel can be corrected by digital temperature compensation. The temperature change rate can be linearly compensated by fitting the slope value of the linear relation through the data acquired at the earlier stage, and the purpose of temperature drift compensation is achieved, but the REFCOEF value (namely, the temperature compensation coefficient value) used is a fixed value obtained by fitting through a single working mode, so that the temperature compensation has the problems of over-compensation (error release) or under-compensation (error trigger) in a non-standard scene, and in order to avoid the specified radiation risk in practical application, the temperature compensation can be reduced (under-compensation) during parameter debugging, but the function of reducing radiation of equipment is easier to trigger, and the user experience is also influenced.

In view of the above technical problems, embodiments of the present application provide a temperature compensation method, where an execution subject of the method may be a temperature compensation device, or a control module for the temperature compensation method in the temperature compensation device. In the embodiment of the present application, a temperature compensation method performed by a temperature compensation device is taken as an example to describe the temperature compensation method provided in the embodiment of the present application.

FIG. 3 is a flow chart illustrating a method of temperature compensation according to an exemplary embodiment.

As shown in fig. 3, the temperature compensation method may include the steps of:

in step 310, N operation modes of the electronic device operating at a first time are determined.

In this embodiment of the application, the first time may be any time when the electronic device operates, and the electronic device may be a mobile phone, a tablet, a computer, or other electronic devices, which is not limited herein. N may be a positive integer, and the N operation modes may be operation modes in which the electronic device operates in different usage scenarios. For example, in a scene where a user watches a video using a mobile phone, the operating mode of the mobile phone is a video mode; in the scene that a user plays games by using the mobile phone, the operating mode of the mobile phone is a game mode; under the scene that a user listens to music by using the mobile phone, the operating mode of the mobile phone is a music mode.

In addition, the N operation modes may be a single operation mode or a combined operation mode, and are not limited herein. For example, if the user only uses the mobile phone to watch the video, the working mode of the mobile phone is a single working mode including the video mode; if the user uses the mobile phone to charge and play a game at the same time, the working mode of the mobile phone is a combined working mode comprising a charging mode and a game mode.

Step 320, obtaining a first mapping relation corresponding to each of the N operating modes.

Here, the first mapping relationship may be a mapping relationship between the temperature compensation coefficient and the operating time when the electronic device operates the operating mode, and the first mapping relationship may be determined according to a target parameter value of the target sensor affected by temperature change at different times when the electronic device operates the corresponding operating mode, and may be used to determine a temperature compensation coefficient value corresponding to the operating mode corresponding to the first mapping relationship at different operating times.

In addition, the first mapping relationship may be a temperature compensation coefficient in a single operation mode, and the temperature compensation coefficient in the embodiment of the present application may be a function varying with time, unlike a fixed temperature compensation coefficient in a conventional scheme. As shown in fig. 4, the single operation mode temperature compensation coefficient 410 in the embodiment of the present application can avoid the overcompensation 430 and the undercompensation 440 of the fixed single operation mode temperature compensation coefficient 420 in the conventional scheme.

Based on this, in an alternative embodiment, the target sensor may be an electromagnetic wave absorption rate SAR sensor, and the target parameter value may be a first detection value acquired by a detection channel in the SAR sensor.

Therefore, through the first mapping relation, when the electronic equipment runs in a single working mode at the first moment, the temperature compensation coefficient value corresponding to the SAR sensor can be determined, and the first detection value collected by the detection channel in the SAR sensor is adjusted, so that the probability of equipment false release or false triggering is reduced.

Step 330, determining temperature compensation coefficient values corresponding to the N operating modes at the first time according to the time when the electronic device has operated the N operating modes and the corresponding first mapping relationships.

Here, the temperature compensation coefficient corresponding to the single operation mode may be a function that varies with time, and in the case where the determined time is the first time, the value of the temperature compensation coefficient may be calculated by substituting the first time into the function. N temperature compensation coefficient values may be determined from the N first mappings. At certain times, one temperature compensation coefficient value may correspond to one operating mode. The temperature compensation coefficient value can be used to determine a first temperature compensation coefficient value for the electronic device at the time.

Step 340, determining a first temperature compensation coefficient value corresponding to the electronic device at the first time according to the temperature compensation coefficient values corresponding to the N operating modes respectively.

Here, the electronic device may operate one or more operation modes at the same time, that is, at a first time, where the temperature compensation coefficient value corresponding to the electronic device is a first temperature compensation coefficient value, and the first temperature compensation coefficient value may be determined according to one or more temperature compensation coefficient values corresponding to the electronic device at the first time. The first temperature compensation coefficient value can be used for adjusting a target parameter value of the target sensor to realize temperature compensation of the target sensor.

For example, when the electronic device only operates one operation mode, the temperature compensation coefficient value corresponding to the operation mode at the first time may be directly determined as the first temperature compensation coefficient value. When the electronic device runs in a plurality of working modes, the plurality of temperature compensation coefficient values corresponding to the plurality of working modes at the first moment can be summed and the like to obtain the first temperature compensation coefficient value.

Based on this, in an alternative embodiment, in case that N ≧ 2, step 340 may specifically include:

acquiring weight distribution information corresponding to the first combined working mode;

and according to the weight distribution information, carrying out weighted summation on the N temperature compensation coefficient values to obtain a first temperature compensation coefficient value corresponding to the electronic equipment at the first moment.

Here, the first combined operation mode may be a combined mode including N operation modes, N ≧ 2. The weight distribution information may include weight values corresponding to the N operation modes, respectively. The N weight values may be N single working mode fitting coefficients, that is, different contribution degrees of temperature compensation coefficient values in the N single working modes, and the sum of the contribution degrees is a fixed constant, and the fixed constant may represent a maximum temperature rise coefficient weight value corresponding to the first combined working mode. The weight values assigned to the same operation mode in different first combined operation modes may be different, and may also be the same.

For example, the calculation formula of the first temperature compensation coefficient value may be:

REFCOEF(T)＝α×REFCOEF(t1)+β×REFCOEF(t2)+…+λ×REFCOEF(tn)

α, β, … λ may be weight values corresponding to the N operation modes, respectively, α + β + … + λ ═ K, K may be a constant, refcoff (T1), refcoff (T2), … refcoff (tn) may be temperature compensation coefficient values corresponding to the N operation modes at time T, respectively, and refcoff (T) may be a first temperature compensation coefficient value corresponding to the first combined operation mode at time T. Here, time T is any time during which the first combined operation mode is continuously operated.

In a specific example, if the temperature compensation coefficient value of the charging mode at 15s is 20, the weighting value is 0.4, the temperature compensation coefficient value of the game mode at 15s is 15, the weighting value is 0.4, the temperature compensation coefficient value of the music mode at 15s is 10, and the weighting value is 0.2, when the user simultaneously uses the mobile phone to charge, play a game, and listen to music, that is, when the mobile phone simultaneously operates the charging mode, the game mode, and the music mode, and the mobile phone continuously operates at 15s of the combined operation mode, the corresponding first temperature compensation coefficient value may be 0.4 × 20+0.4 × 15+0.2 × 10 ═ 16.

Specifically, as shown in fig. 5, the process of determining the first temperature compensation coefficient value may first determine each single operating mode included in the first combined operating mode 510 at time T and the corresponding temperature compensation coefficient value, specifically including: the temperature compensation coefficient refcref (t1) corresponding to the charging mode, the temperature compensation coefficient refcref (t2) corresponding to the video mode, the temperature compensation coefficients refcref (t3) and … corresponding to the game mode, and the temperature compensation coefficient refcref (tn) corresponding to the music mode are determined, and the weight distribution information 520 corresponding to the first combined working mode 510 is determined, so that the weighted summation can be performed, and the first temperature compensation coefficient value refcref (t) of the electronic device at the first moment is calculated.

In a specific example, on the premise that the first combined operation mode includes a charging mode, a game mode and a music mode, and the preset weighting value corresponding to the charging mode in the first combined operation mode is 0.4, the weighting value corresponding to the game mode is 0.4, and the weighting value corresponding to the music mode is 0.2, if the current time is 15s for operating the first combined operation mode, according to the mapping relation corresponding to each mode, the temperature compensation coefficient value at the 15 th s of the charging mode is calculated to be 20, the temperature compensation coefficient value at the 15 th s of the game mode is calculated to be 15, and the temperature compensation coefficient value at the 15 th s of the music mode is 10, then the corresponding first temperature coefficient value compensation of the mobile phone at the current time may be 0.4 × 20+0.4 × 15+0.2 × 10 ═ 16.

Therefore, the temperature compensation coefficient values corresponding to the single working mode are subjected to weighted summation to obtain the temperature compensation coefficient values corresponding to the combined working mode, the temperature compensation coefficients of different temperature rise factors can be combined and decomposed, and therefore the accuracy of temperature compensation can be improved.

And 350, adjusting a target parameter value of a target sensor in the electronic equipment according to the first temperature compensation coefficient value so as to realize temperature compensation of the target sensor.

Here, the first temperature compensation coefficient value may be determined by the above method, so that the target parameter value collected by the target sensor in the electronic device may be adjusted according to the first temperature compensation coefficient value. The target parameter value may be a detection value acquired by the SAR sensor, or may be a fitting parameter that is greatly affected by temperature rise or environmental disturbance, such as photosensitive glass parameter fitting, optical scheme calibration under a screen, and the like, which is not limited herein. For example, the first detection value acquired by the detection channel in the SAR sensor may be adjusted according to the first temperature compensation coefficient value, so as to implement temperature compensation for the SAR sensor.

Therefore, the first mapping relation corresponding to each working mode is the mapping relation between the temperature compensation coefficient and the time, and is the mapping relation between the temperature compensation coefficient and the running time when the electronic equipment runs the working mode, so that the temperature compensation coefficient value in the single working mode or the combined working mode is not restricted by the fixed temperature compensation coefficient value and can be dynamically changed along with the change of the time. In addition, because the target sensor is affected by temperature changes at different moments differently, the embodiment of the application can dynamically compensate by using the dynamically changed temperature compensation coefficient value aiming at the target parameter value affected by the temperature changes at different moments of the target sensor in the current working mode, so that more accurate temperature compensation adjustment of the target parameter can be realized, the problem of under-compensation or over-compensation caused by temperature compensation adjustment of the fixed temperature compensation coefficient value obtained by fitting under a single scene is avoided, and the accuracy of temperature compensation is improved.

Furthermore, in an alternative embodiment, before step 320, the temperature compensation method may further include:

under the condition of running in a target working mode, acquiring M first detection values acquired by a target sensor at M moments;

according to the time values corresponding to the M moments and the M first detection values, fitting to obtain a functional relation between the first detection values and the running time;

the functional relation is subjected to derivation to obtain a first mapping relation corresponding to the target working mode;

based on this, step 350 may specifically include:

and adjusting a first detection value acquired by the SAR sensor at a first moment according to the first temperature compensation coefficient value.

Here, the target operation mode may be any one of N operation modes, M may be a positive integer, and M ≧ 2. The functional relationship may be obtained by fitting, in a case where the electronic device operates the target operating mode, the first detection value, which is a real-time detection value acquired by the target sensor at different times, with the operated time as an independent variable.

For example, the derivation of the functional relationship to obtain the first mapping relationship may be as follows:

wherein t may be an electronThe time that the device has been operating in the target operating mode, REFCOEF (t), may be a temperature compensation coefficient value, U, corresponding to the target operating mode_sefulAnd (t) may be a first detection value acquired by a detection channel of the target sensor at time t in the target working mode.

Therefore, under the condition of running in the target working mode, the obtained multiple first detection values of the target sensor at multiple moments are fitted to obtain a functional relation, so that the first mapping relation is determined, the temperature compensation coefficient value of the target sensor at the first moment under the condition of running in the target working mode can be calculated, and the first temperature compensation coefficient value of the target sensor under the condition of running in the combined working mode can be conveniently calculated subsequently.

In addition, for the SAR sensor, in the conventional scheme, if two or more sets of temperature compensation coefficient values are called, since the temperature compensation coefficient values jump during switching, an irreversible disturbance is generated on a target parameter value of the target sensor during the coefficient switching process, thereby causing problems of false release, false alarm, approach and the like.

Specifically, as shown in fig. 6, switching from the temperature compensation coefficient value a corresponding to the operation mode a to the temperature compensation coefficient value B corresponding to the operation mode B may cause the detection value usefull (n) acquired and compensated by the detection channel to jump from the first point 610 to the second point 620, resulting in the false alarm approaching; switching from the temperature compensation coefficient value B corresponding to the operating mode B to the temperature compensation coefficient value C corresponding to the operating mode C may cause the real-time detection value acquired by the detection channel to jump from the third point 630 to the fourth point 640, resulting in a false release.

In order to solve the problem of the detection value jump, based on the step 310 and 350, in a possible embodiment, in the case that the electronic device is switched from the N operation modes to the T operation modes at the second time, as shown in fig. 7, the temperature compensation method may further include: step 341- > 343, wherein:

step 341, determining a second temperature compensation coefficient value corresponding to the electronic device at the second time point in the case of operating N operation modes, and determining a third temperature compensation coefficient value corresponding to the electronic device at the second time point in the case of operating T operation modes.

Here, T may be a positive integer, and T operation modes are not exactly the same as N operation modes. The determination methods of the second temperature compensation coefficient value and the third temperature compensation coefficient value are the same as the determination method of the first temperature compensation coefficient value, and are not described herein again.

In step 342, a correction value is determined according to the second temperature compensation coefficient value, the third temperature compensation coefficient value, and the target reference value.

Here, the target reference value may be a second detection value acquired by the reference channel in the SAR sensor at a second time. The correction value can be a corrected disturbance quantity, and disturbance correction can solve the problem of jump of a compensated detection value in the process of switching different temperature compensation coefficients. The jump is mainly due to the difference of front and back compensation caused by the switching of different temperature compensation coefficients.

Based on this, in an alternative embodiment, step 342 may specifically include:

and multiplying the difference between the second temperature compensation coefficient value and the third temperature compensation coefficient value by the target reference value to obtain a correction value.

Here, the disturbance correction may be performed mainly based on the calculated correction value, and specifically, may be performed by filling up an intercept value in real time after switching the temperature compensation coefficient value, and the intercept value may be equal to the correction value.

In one specific example, the correction value may be calculated by the formula:

μ＝Useful(m+)-Useful(m-)＝(REFCOEF(T1)-REFCOEF(T2))×Reference(m)

where μmay be a correction value, Useful (m +) may be a real-time value of a detection channel before m timeslots, Useful (m-) may be a real-time value of a detection channel after m timeslots, refcoff (T1) may be a temperature compensation coefficient value before switching, refcoff (T2) may be a temperature compensation coefficient value after switching, and reference (m) may be a real-time value of a reference channel at time m.

Therefore, by the calculation mode, the correction value can be calculated, so that the jump of the detection value can be corrected in the mode switching process, and the problem of false triggering or false releasing is avoided.

And 343, adjusting the first detection value acquired by the SAR sensor at the second moment according to the third temperature compensation coefficient value and the correction value.

Here, the correction value may be added on the basis of the target detection value obtained by compensating the first detection value acquired by the detection channel in real time based on the third temperature compensation coefficient value to obtain the final corrected detection value.

In a specific example, as shown in fig. 8, after the operating mode is changed, a temperature compensated detection data curve 810 can be obtained, and at this time, a correction value 820 can be added on the basis of the detection data curve 810 to obtain a corrected data curve 830, so as to avoid the problem of false alarm approaching caused by jump of the detection value; if the operation mode is further changed, a temperature compensated detection data curve 840 can be obtained, and at this time, a correction value 850 can be added on the basis of the detection data curve 840 to obtain a corrected data curve 860, so as to avoid the problem of false release caused by jump of the detection value.

Therefore, by calculating the jump amount before and after mode switching, namely the correction value, of the compensated detection value of the first detection value, the correction value is used for correcting the temperature-compensated detection value of the first detection value, the disturbance of the detection value caused in the dynamic switching process of the temperature compensation coefficient can be effectively avoided, and the problems of mistaken release and false alarm approaching are solved.

To better describe the whole scheme, based on the above embodiments, taking the temperature compensation method of the SAR sensor as an example, as a specific example, as shown in fig. 9, the temperature compensation method may include steps 901-911, which will be explained in detail below.

Step 901, initialize system configuration.

Step 902, call the default temperature compensation coefficient value of the system.

Here, temperature compensation is temperature compensation. And calling a default temperature compensation coefficient value of the system to perform temperature compensation for the working mode which is not preset or identified by the system.

Step 903, whether the special single working mode is identified.

Here, the operation mode in which the electronic device operates is recognized, and if the single operation mode set for the system is recognized, step 908 is executed, and if the single operation mode not set for the system is recognized, step 904 is executed.

And step 904, whether the combined working mode is identified.

Here, if the combined operation mode set for the system is recognized, step 905 is executed, and if the combined operation mode not set for the system is recognized, step 902 is executed.

Step 905, obtaining a temperature compensation coefficient value of the single working mode.

Here, the combined working mode may be analyzed to obtain a plurality of single working modes, and then the temperature compensation coefficients corresponding to the single working modes are extracted, and the method for calculating the temperature compensation coefficients corresponding to the single working modes is not described herein again.

And step 906, configuring the weight.

Here, the weight distribution information corresponding to the combined operation mode may be acquired, and the weight values may be configured for the temperature compensation coefficients corresponding to the respective single operation modes based on the weight distribution information.

Step 907, calculate the temperature compensation coefficient value of the combined working mode.

Here, a weighted summation calculation may be performed based on the temperature compensation coefficient corresponding to each single operation mode and the weight value corresponding thereto, so as to obtain a temperature compensation coefficient value of the combined operation mode, and then step 909 is performed.

Step 908, call the temperature compensation coefficient value for the single mode of operation.

Here, if the operation mode of the electronic device is identified as the single operation mode, the temperature compensation coefficient value of the single operation mode is called, and the specific calculation method of the temperature compensation coefficient value of the single operation mode is not described herein again.

In step 909, a correction value is calculated.

Here, in order to avoid the occurrence of detection value jump when the operating mode is switched, which may cause false alarm approaching or false release, interference correction may be performed by adding a correction value based on the detection value, and a specific calculation method of the correction value is not described herein again.

Step 910, writing the temperature compensation coefficient value and the correction value.

Here, by writing the temperature compensation coefficient value and the correction value into the processor, it is possible to more accurately output the detection value after continuous compensation and correction.

Step 911, end or not.

Here, whether the ending condition is met is determined, and the ending condition may be shutdown or exiting from the current operating mode, or may be other conditions, which is not limited herein. If the end condition is satisfied, the execution ends, and if not, step 903 is executed.

Therefore, the first mapping relation corresponding to each working mode is the mapping relation between the temperature compensation coefficient and the running time, so that the temperature compensation coefficient value in either a single working mode or a combined working mode is not constrained by the fixed temperature compensation coefficient value and can be dynamically changed along with the change of time. In addition, because the target sensor is affected by temperature changes at different moments differently, the embodiment of the application can dynamically compensate by using the dynamically changed temperature compensation coefficient value aiming at the target parameter value affected by the temperature changes at different moments of the target sensor in the current working mode, so that more accurate temperature compensation adjustment of the target parameter can be realized, the problem of under-compensation or over-compensation caused by temperature compensation adjustment of the fixed temperature compensation coefficient value obtained by fitting under a single scene is avoided, and the accuracy of temperature compensation is improved.

Based on the above temperature compensation method, in one possible embodiment, there is a temperature compensation software system, as shown in fig. 10, which may include: the combined working mode identification module 1010, the single working mode temperature compensation coefficient value refining module 1020, the weight distribution module 1030, the combined working mode temperature compensation coefficient value calculation module 1040, the correction value calculation module 1050 and the temperature compensation coefficient value and correction value compensation 1060.

the correction value calculation module 1050 may be configured to calculate a correction value according to the temperature compensation coefficient value before and after switching the working mode and the target reference value, and a specific calculation method is not described herein again;

the temperature compensation coefficient value and correction value compensation 1060 can be used to input the temperature compensation coefficient value and correction value into the processor, so that the detection value output by the system is more accurate and continuous.

Therefore, the first mapping relation corresponding to each working mode is the mapping relation between the temperature compensation coefficient and the running time, so that the temperature compensation coefficient value in either a single working mode or a combined working mode is not constrained by the fixed temperature compensation coefficient value and can be dynamically changed along with the change of time. In addition, because the target sensor is affected by temperature changes at different moments differently, the embodiment of the application can dynamically compensate by using the dynamically changed temperature compensation coefficient value aiming at the target parameter value affected by the temperature changes at different moments of the target sensor in the current working mode, so that more accurate temperature compensation adjustment of the target parameter can be realized, the problem of under-compensation or over-compensation caused by temperature compensation adjustment of the fixed temperature compensation coefficient value obtained by fitting under a single scene is avoided, and the accuracy of temperature compensation is improved.
