Detailed Description

In order to make the technical problems, technical solutions and advantageous effects to be solved by the present application clearer, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.

Referring to fig. 1, an embodiment of the present application provides a sensor calibration method, which is performed by a sensor calibration apparatus when calibrating a sensor. The sensor calibration method includes S11 to S14.

S11: and reading the identity characteristic parameters of the sensor to be calibrated.

The identity characteristic parameter of the sensor to be calibrated can be a product code stored in a storage unit of the sensor to be calibrated, and the sensor calibration device is electrically connected with the sensor to be calibrated and obtains the product code by communicating with the sensor to be calibrated so as to obtain the identity characteristic parameter of the sensor to be calibrated. The identity characteristic parameters of the sensor to be calibrated can also be stored in a two-dimensional code or a bar code attached to the surface of the sensor to be calibrated, and the sensor calibration device obtains the identity characteristic parameters of the sensor to be calibrated by scanning the two-dimensional code or the bar code.

When the identity characteristic parameter of the sensor to be calibrated is a product code, the product code comprises the type, model, identification code and the like of the sensor to be calibrated. The type of the sensor to be calibrated refers to what type of sensor the sensor to be calibrated is, and includes, but is not limited to, a temperature sensor, a humidity sensor, an illumination sensor, a pressure sensor, a magnetic strength sensor, a sound sensor, and an olfactory sensor. The first three bits of the product code are fixed identification codes &12, the fourth bit to the sixth bit carry the type information of the sensor to be calibrated, and the seventh bit to the ninth bit carry the model information of the sensor to be calibrated. For example, when the product code is aaabbbcc type, the specific product code is &12a12D23, when the sensor calibration device reads the identification code &12, the sensor calibration device recognizes the identification code as the identification code of the sensor to be calibrated, then the last three bits of the identification code are used as a12 as the code for recognizing the category of the sensor to be calibrated, and then the last three bits of the category code, D23, are used as the code for recognizing the model of the sensor to be calibrated. In practical application, the information of the type and model of the sensor to be calibrated may be integrated into the same string of codes, for example, the product code is &12a12D23, and after the sensor calibration device reads the identification code &12, the type and model of the sensor to be calibrated are simultaneously identified directly according to the last six-bit code a12D23 of the identification code.

The type of the sensor to be calibrated refers to what type of sensor the sensor to be calibrated is, and includes, but is not limited to, a temperature sensor, a humidity sensor, an illumination sensor, a pressure sensor, a magnetic strength sensor, a sound sensor, and an olfactory sensor. The model of the sensor to be calibrated refers to the same kind of sensor with different parameters. For example, taking the sensor to be calibrated as a temperature sensor as an example, parameters such as temperature sensing intervals, sensing accuracy and the like of different types of temperature sensors may be different, for example, a temperature sensing interval of one type of temperature sensor is 0 to 50 degrees celsius, and the accuracy is 1 degree celsius, and a temperature sensing interval of another type of temperature sensor is 20 to 30 degrees celsius, and the accuracy is 0.5 degree celsius.

When the sensor calibration method of the present embodiment is applied to a single type of sensor, since the type of the sensor is uniquely determined before calibration, it is not necessary to identify the type of the sensor to be calibrated, and only the model of the sensor to be calibrated needs to be identified.

S12: and calling a calibration program matched with the sensor to be calibrated according to the identity characteristic parameters.

The sensor calibration device is preset with calibration programs of a plurality of sensors of different types and different models, wherein one or more models of calibration programs can be preset for the same type of sensor. In the sensor calibration device, the identity characteristic parameters of the sensor to be calibrated are all provided, and only one calibration procedure corresponds to the identity characteristic parameters. The sensor calibration device selects a corresponding calibration program according to the identity characteristic parameters of the sensor to be calibrated, and the calibration program is taken out from the plurality of programs to be used as an execution program for calibrating the sensor to be calibrated.

The calibration program which is the same as the type and the model of the sensor to be calibrated is selected from a plurality of preset calibration programs, so that different types and/or different models of sensors to be calibrated can be calibrated through different calibration programs.

S13: and calibrating the sensing parameters of the sensor to be calibrated through the adaptive calibration program.

The sensing parameters comprise actual measurement parameters of the sensor to be calibrated and true values corresponding to the actual measurement parameters, a mapping relation is formed between the actual measurement parameters and the true values, and any actual measurement parameter has only one true value corresponding to the actual measurement parameter.

The sensor calibration device tests real actual measurement parameters corresponding to true value parameters of the sensor to be calibrated when executing a calibration program, and replaces the real actual measurement parameters with the last actual measurement parameters to form a new corresponding relationship with the true value parameters, thereby realizing the calibration of the sensing parameters of the sensor to be calibrated.

For example, taking the sensor to be calibrated as a temperature sensor, the measured parameter of the temperature sensor is a voltage value, and the true parameter of the temperature sensor is celsius degree. The temperature sensor stores a plurality of true values and a plurality of measured parameters corresponding to the true values one by one, and the sensor calibration device calibrates the measured parameters corresponding to the true values stored in the temperature sensor when executing a calibration program; for example, one of the true value parameters of the temperature sensor is 10 degrees celsius, the actual measurement parameter corresponding to the true value parameter is 0.4mV, when the temperature sensor is calibrated, the actual measurement parameter of the temperature sensor at the ambient temperature of 10 degrees celsius is obtained, for example, the actual measurement parameter is 0.38mV, and the true value parameter of 10 degrees celsius corresponding to the actual measurement parameter is taken as the calibrated sensing parameter.

According to the sensor calibration method, the identity characteristic parameters of the sensor to be calibrated are read, and the calibration program matched with the sensor to be calibrated is called according to the identity characteristic parameters to calibrate the sensing parameters of the sensor to be calibrated, so that different sensors to be calibrated can be calibrated.

Referring to fig. 2, in an embodiment, fig. 2 shows a flowchart of an implementation of the sensor calibration method S13 provided in the embodiment of the present application, and specifically, calibrating the sensing parameter of the sensor to be calibrated through an adaptive calibration procedure includes steps S131 to S133.

S131: and adjusting the measured quantity of the detection environment of the sensor to be calibrated.

The sensor calibration device is provided with a closed cavity, the sensor to be calibrated is arranged in the cavity, and the sensor to be calibrated is used for detecting the measured quantity in the cavity. The sensor calibration device may change the measurands in the chamber including, but not limited to, temperature, humidity, pressure, magnetic field strength, and light level.

The sensor calibration device adjusts the measurand of the detection environment where the sensor to be calibrated is located by changing the measurand in the cavity. By adjusting the measurands of the detection environment, the sensor to be calibrated can perform corresponding detection calibration under different measurands of the detection environment.

For example, taking a sensor to be calibrated as a temperature sensor, the temperature sensor detects a measured value of a detection environment where the temperature sensor is located as a temperature, and the temperature sensor is located in the detection environments with different temperatures by adjusting the temperature of the detection environment, so as to detect the temperatures of the detection environments with different temperatures for subsequent calibration.

The measured adjusting range and the adjusting precision of the detecting environment are correspondingly designed according to the sensing range and the sensing precision to be calibrated of the sensor to be calibrated.

S132: respectively acquiring real measured parameters of a sensor to be calibrated in detection environments based on different measured quantities

The sensor to be calibrated has different real measured parameters in different measured detection environments, and the different real measured parameters of the sensor to be calibrated in the different measured detection environments are respectively obtained.

For example, taking a sensor to be calibrated as a temperature sensor as an example, the voltage values corresponding to the temperature sensor in the detection environments of 0, 1, 2.. 30 degrees celsius are respectively obtained. In one embodiment, a sensing curve of the sensor to be calibrated can be constructed by using the acquired multiple actual measurement parameters, so that the subsequent analysis and management of sensing data of the sensor to be calibrated are facilitated.

S133: and taking the actual measurement parameters corresponding to the sensor to be calibrated as the calibrated sensing parameters. For example, taking a sensor to be calibrated as a temperature sensor, the detection range of the temperature sensor is 0-30 degrees celsius, the detection precision of the temperature sensor is 1 degree celsius, the measured quantity of the detection environment is temperature, and the actual measurement parameter of the temperature sensor is a voltage value. The temperature of the detection environment where the temperature sensor is located is sequentially adjusted from 0 ℃ to 1 ℃ in a single increment until the temperature of the detection environment reaches 30 ℃, the voltage value corresponding to each temperature of the temperature sensor from 0 ℃ to 30 ℃ is respectively obtained, and the voltage value corresponding to each temperature of the temperature sensor from 0 ℃ to 30 ℃ is used as the calibrated sensing parameter of the temperature sensor.

Referring to fig. 3, in an embodiment, fig. 3 shows a flowchart of an implementation of the sensor calibration method S131 provided in this application, and in particular, adjusting the measurands of the detection environment of the sensor to be calibrated includes steps S1311 and S1312.

S1311: reading a plurality of true value parameters stored by the sensor to be calibrated.

When the sensor to be calibrated leaves the factory, a plurality of true value parameters are stored, and the true value parameters represent the detection range and the detection precision of the sensor to be calibrated. The data writing position and the data reading position of a plurality of true value parameters are usually found through the address code of the sensor to be calibrated.

S1312: and sequentially adjusting the measurands of the detection environment according to a plurality of true-value parameters.

The measured value of the detection environment and the true value parameter of the sensor to be calibrated are the same parameter, for example, the measured value of the detection environment and the true value parameter of the sensor to be calibrated are simultaneously temperature, humidity or pressure, etc. The measured quantity of the detection environment is sequentially adjusted according to a plurality of true value parameters stored by the sensor to be calibrated, and actual measurement parameters corresponding to all true value parameters of the sensor to be calibrated can be calibrated.

Illustratively, taking a sensor to be calibrated as a temperature sensor as an example, a detection range of the sensor to be calibrated is 0-30 degrees celsius, and a detection precision of the sensor to be calibrated is 1 degree celsius, then the sensor to be calibrated stores each degree celsius from 0 to 30 degrees celsius as a true value parameter when leaving a factory, the number of the true value parameters is 31, and the temperature of the detection environment is sequentially adjusted to be 0-30 degrees celsius according to the 31 true value parameters, so that actual measurement parameters corresponding to the 31 true value parameters of the sensor to be calibrated are all calibrated.

Referring to fig. 4, in an embodiment, the sensor calibration method further includes step S14.

S14: and storing the calibrated sensing parameters in the sensor to be calibrated.

The sensor calibration device outputs the calibrated sensing parameters to the sensor to be calibrated so that the sensor to be calibrated stores the calibrated sensing parameters. When the sensor to be calibrated is applied to the terminal equipment as the sensing equipment, the terminal equipment reads the calibrated sensing parameters stored in the calibrated sensor to be calibrated, and uses the calibrated sensor to be calibrated according to the calibrated sensing parameters.

For example, taking a sensor to be calibrated as a temperature sensor as an example, when the terminal device needs to measure temperature by using the temperature sensor, the terminal device reads the sensing parameter of the calibrated temperature sensor and measures temperature according to the sensing parameter.

The sensor to be calibrated can cover the calibrated sensing parameter with the sensing parameter stored last time, so that the sensor to be calibrated does not need to store multiple sensing parameters at the same time, and the requirement on the data storage size of the sensor to be calibrated is reduced.

In addition, the calibrated sensing parameters and the sensing parameters stored in the sensor to be calibrated last time can be stored in the sensor to be calibrated together, so that the sensor to be calibrated can be restored to the sensing parameters stored last time when the sensing parameters stored and calibrated in the sensor to be calibrated are abnormal.

In one embodiment, the identity characteristic parameters of the sensor to be calibrated include model characteristic parameters.

In the embodiment, the identity of the sensor to be calibrated is identified through the model characteristic parameters, and the subsequent calling of the calibration program matched with the sensor to be calibrated according to the model characteristic parameters is more efficient.

In one embodiment, the sensor to be calibrated is at least one of a temperature sensor, a humidity sensor, an illuminance sensor, a pressure sensor, a magnetic sensor, a sound sensor, and an olfactory sensor.

In the above embodiments, the specific examples of the sensor calibration method mainly use a temperature sensor as an example for description, and when the sensor to be calibrated is another type of sensor, such as a humidity sensor, an illuminance sensor, a pressure sensor, a magnetic intensity sensor, a sound sensor, or an olfactory sensor, the calibration process for these types of sensors can refer to the calibration process for a reference temperature sensor, which is not described herein again.

And the parameter reading and writing module 510 is configured to read the identity characteristic parameters of the sensor to be calibrated.

And the calibration module 520 is connected with the parameter reading and writing module 510 and is configured to call a calibration program matched with the sensor to be calibrated according to the identity characteristic parameters and calibrate the sensing parameters of the sensor to be calibrated through the matched calibration program.

And the calibration unit is configured to call a temperature calibration program matched with the temperature sensor according to the identity characteristic parameters, and adjust the temperature of the cavity according to the temperature calibration program so as to calibrate the temperature sensing parameters of the temperature sensor.

In this embodiment, the temperature sensor to be calibrated is placed in the accommodating cavity, and the calibration unit obtains the identity characteristic parameters of the temperature sensor, so as to call a temperature calibration program matched with the temperature sensor to be calibrated, and sequentially adjust the temperature of the accommodating cavity according to the temperature calibration program, so as to calibrate all temperature sensing parameters in the detection range of the temperature sensor.

The temperature sensors to be calibrated in the same type are placed in the accommodating cavity, and the temperature sensing parameters of the temperature sensors are calibrated simultaneously.

In one embodiment, the sensor to be calibrated includes a memory unit.

The storage unit is used for storing the calibrated sensing parameters.

The sensing parameters of the sensor to be calibrated are stored in the storage unit of the sensor to be calibrated, and when the calibrated sensor to be calibrated is used, the sensing parameters stored in the calibrated sensor to be calibrated can be read for subsequent use.
