Detailed Description

The embodiment of the invention provides an intelligent wristwatch and a time calibration method and device thereof, which can realize automatic calibration of the time of the intelligent wristwatch in the use process, avoid the problems of low efficiency and low precision of manual calibration and are beneficial to improving the use experience of users.

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, fig. 1 is a schematic flowchart illustrating a time calibration method of an intelligent wristwatch according to an embodiment of the present invention. The method comprises the following steps:

s110: when a pointer appears at a preset position, acquiring pointer information of the pointer;

it should be noted that, in this embodiment, a preset position is determined on the dial in advance, and each pointer on the intelligent wristwatch is in one turn in the rotation process, so that a moment passes through the preset position in the pointer rotation process, and each pointer corresponds to corresponding time when passing through the preset position. In the application, when the pointer appears at the preset position, namely when the pointer rotates to the preset position, the pointer information of the pointer is obtained.

S120: identifying the pointer type of the pointer according to the pointer information and the corresponding relation between the pointer information and the pointer type which is established in advance;

specifically, the corresponding relationship between the pointer information and the pointer type may be pre-established, that is, the pointers of different pointer types correspond to a specific pointer information, so that the pointer type of the pointer can be obtained according to the pointer information and the corresponding relationship between the pointer information and the pointer type after the pointer information of the pointer currently rotated to the preset position is obtained.

S130: determining the current pointer time corresponding to the pointer type according to the pointer type and the preset position;

specifically, the current time corresponding to the pointer category can be determined according to the pointer category and the preset position of the pointer, for example, the preset position is a position corresponding to the number 12 on the dial, and if the pointer category is minute, the current time corresponding to the pointer category is 0 minute, and if the pointer category is hour hand, the current time corresponding to the pointer category is 0 hour or 12 hours.

S140: judging whether the pointer time is consistent with the corresponding part of the RTC time of the clock chip, if not, entering S150;

s150: the gear box is controlled to rotate correspondingly to adjust the pointer so that the pointer time is consistent with the corresponding part of the RTC time.

It should be noted that, after obtaining the current pointer time, the time portion corresponding to the above-mentioned pointer type in the RTC time of the hour hand chip may be read, and whether the corresponding portion of the pointer time and the RTC time is consistent is compared, if the corresponding portion of the pointer time and the RTC time is inconsistent, it indicates that the pointer time is inaccurate, and it is necessary to adjust the corresponding pointer, and specifically, the gear box 4 may be controlled to rotate correspondingly to drive the corresponding pointer to rotate, so as to adjust the corresponding pointer, and make the pointer time corresponding to the pointer consistent with the corresponding portion of the RTC time.

For example, if the pointer category of the pointer rotated to the preset position is minute, and the preset position is the position corresponding to the number 12, the current pointer time is 0 minute, and if the RTC time is 0: and 58 minutes is the part corresponding to the minute hand, and at this time, the minute hand is faster by two seconds, so that the gear part corresponding to the minute hand in the gear box can be controlled to perform reverse adjustment, so that the minute hand time after adjustment is 58 minutes and the minute hand time in the RTC time are kept consistent.

It should be further noted that, if the intelligent wristwatch includes a plurality of pointers, and when a plurality of pointers appear at a preset position at the same time, the pointer information of each pointer can be acquired respectively, and a corresponding pointer type is determined according to the pointer information of different pointers, then a pointer time corresponding to each pointer is further determined according to each pointer type and the preset position, then whether the pointer time of each pointer is accurate is determined according to a corresponding part of RTC time, and the pointer with inaccurate pointer time is adjusted and calibrated respectively by controlling the rotation of the gear box.

In addition, it should be noted that, in order to improve the calibration accuracy in practical application, the preset positions are not limited to one, and may also be multiple, that is, the pointer types of the pointers appearing at the multiple preset positions may be identified, the pointer time is determined according to the pointer type and the corresponding preset position, and then the corresponding pointer is calibrated according to the RTC time, so as to improve the calibration accuracy, specifically, one preset position or multiple preset positions may be set and determined according to actual needs, which is not specially limited in this embodiment.

It can be seen that, in the present application, pointer information is obtained from a pointer appearing at a preset position, a pointer category of the pointer is identified according to the pointer information and a pre-established correspondence between the pointer information and the pointer category, then, a current pointer time corresponding to the pointer category can be determined according to the pointer category and the preset position, whether the pointer time is accurate can be determined according to the pointer time and a corresponding part of a clock chip RTC time, when the pointer time is not consistent with the corresponding part of the RTC time, the pointer time is not accurate, at this time, the pointer can be correspondingly adjusted by controlling a gear box to correspondingly rotate, so that the adjusted pointer time is consistent with the RTC time, and therefore, the time of the intelligent wristwatch is calibrated; the embodiment of the invention can realize automatic calibration of the time of the intelligent wristwatch in the using process, avoids the problems of low efficiency and low precision of manual calibration and is beneficial to improving the use experience of users.

The present embodiment further describes and optimizes the technical solution with respect to the previous embodiment. Specifically, the method comprises the following steps:

furthermore, a plurality of pointers of the intelligent wristwatch are provided, and each pointer is provided with a coating with different characteristics;

the pointer information is the characteristic information of the corresponding pointer surface coating;

then, according to the pointer information and the pre-established correspondence between the pointer information and the pointer category, the process of identifying the pointer category of the pointer is as follows:

and determining the pointer type of the pointer according to the characteristic information and the pre-established corresponding relationship between the characteristic information and the pointer type.

It should be noted that, in the intelligent wristwatch in this embodiment, there are a plurality of hands, for example, including an hour hand and a minute hand, or including an hour hand, a minute hand and a second hand, which are specifically set according to actual needs, and this embodiment is not particularly limited.

Specifically, when being equipped with a plurality of pointers in the intelligent wristwatch, then in order to distinguish the pointer category of each pointer, can set up the coating that has different characteristics on each pointer, can adopt different characteristic information sign different pointers, promptly, a characteristic information corresponds a pointer category to can determine corresponding pointer category according to the characteristic information of pointer.

Of course, in practical applications, besides the coating with different characteristics is provided on each pointer, each pointer can be set as a pointer with different length, or each pointer can be set as a pointer with different width, as long as the pointer can be uniquely calibrated according to the pointer information specific to each pointer, so that the corresponding pointer type can be uniquely determined according to the pointer information, the corresponding pointer time is further read, and the pointer is calibrated according to the corresponding part of the RTC time. It should be noted that, when the lengths or widths of the pointers are different, the length of the pointer at the lower layer may be made longer than the length of the pointer at the upper layer, and the width of the pointer at the lower layer may be made wider than the width of the pointer at the upper layer, so that the pointer information of the pointer at the lower layer can still be obtained when the pointers overlap.

Furthermore, each pointer is provided with a coating with different colors; the characteristic information is spectral information.

Specifically, in practical applications, coatings of different colors may be applied to each pointer, and since the spectral information corresponding to the coatings of different colors is different, the characteristic information of each pointer may be spectral information, and specifically, the pointer category of the pointer may be further determined by identifying the spectral information of the coating currently appearing on the pointer at the preset position. Of course, since the gray scale information corresponding to the coatings of different colors is different, the characteristic information in practical application may also be gray scale information, and the corresponding relationship between each gray scale information and the pointer category may be pre-established, so that the corresponding pointer category may be further determined according to the gray scale information corresponding to the coating currently appearing on the pointer at the preset position.

In addition, in practical application, besides the color of the coating on each pointer is different, the coating with different shapes can be arranged on each pointer; the characteristic information is shape information.

That is, different pointers can be further identified by coatings of different shapes, that is, a corresponding relationship between shape information and a pointer category can be established in advance, the pointer category corresponding to the pointer is further determined according to the coating shape information of the pointer currently rotated to the preset position, and the pointer is further calibrated according to the corresponding part of the RTC time.

Certainly, in practical application, the application is not limited to only using the coating layer disposed on the pointer to identify the pointer, but also can manufacture a pattern uniquely corresponding to each pointer on the pointer to identify each pointer, and specifically, which identifiers are used to distinguish each pointer can be determined according to actual needs, which is not particularly limited in this embodiment.

Furthermore, the pointer on the upper layer of each pointer is provided with a hollow-out groove, so that when the pointer is overlapped with the pointer on the lower layer, the coating layer arranged on the pointer on the lower layer is exposed from the hollow-out groove.

It should be noted that, when a plurality of hands are provided in the intelligent wristwatch and each hand shares a rotating shaft, at a certain time, the corresponding hand may coincide, for example, at the position of the numeral 12, three hands of the hour hand, the minute hand and the second hand coincide every 12 hours, and the minute hand and the second hand coincide every 1 hour, so that, if the preset position is set to the position corresponding to the numeral 12, there may be a certain time that the minute hand and the second hand coincide, or three hands of the hour, the minute and the second hand coincide, and at this time, in order to be able to identify the coating characteristic information on the hand located at the lower layer, in this embodiment, a hollow groove may be provided in the upper layer hand in each hand in advance, and when each hand coincides, the coating on the hand located at the lower layer may be exposed from the hollow groove at the upper layer, so that the corresponding characteristic information is acquired.

For example, when the intelligent wristwatch only includes the hour hand and the minute hand, if the minute hand is located hour hand lower floor, at this moment, can set up the fretwork groove in the hour hand with the position that is located the coating on the minute hand and corresponds, when that is also the hour hand and the minute hand coincide, the coating that is located the minute hand can expose through this fretwork groove to the characteristic information of this coating is gathered. When the intelligent wristwatch comprises three hour-minute-second hands, if the minute hand is positioned at the lower layer of the hour hand and the second hand is positioned at the lower layer of the minute hand, a hollow groove can be formed in the position, different from the coating on the hand, of the minute hand, and the position of the hollow groove corresponds to the position of the coating on the second hand, so that when the minute hand and the second hand are superposed, the coating on the second hand can be exposed from the hollow groove on the minute hand.

Of course, even if there are multiple hands, different hands can be further detected separately by setting the acquisition frequency, for example, the information at the preset position can be acquired once per second, so that the hand information of the second hand can be acquired in time when the second hand is detected to appear; the information at the preset position can be acquired every minute, so that the pointer information of the minute hand can be acquired in time when the minute hand appears at the preset position; it may also be arranged to obtain the information at the preset position once per hour so that the pointer information of the hour hand can be obtained in time when the hour hand appears at the preset position.

It should be noted that, when the hands overlap, only one of the hands may be detected and calibrated, for example, when the preset position is located at the position corresponding to the number 12, it may be set that, every hour, when the minute hand and the second hand overlap, only the hand information of the minute hand is acquired, and the minute hand is calibrated, specifically, the minute hand may be located on the upper layer of the second hand, so that only the hand information of the upper layer hand may be acquired, and the hand information may be calibrated according to the hand type and the RTC time; and the method can also set that only the pointer information of the hour hand is acquired and the hour hand is calibrated when three hands of hour, minute and second coincide every 12 hours, and specifically, the hour hand can be positioned on the uppermost layer, so that only the pointer information of the pointer on the uppermost layer needs to be acquired when the three hands coincide and the pointer information is calibrated according to the pointer type and the RTC time.

On the basis of the above embodiments, the embodiment of the present invention further provides a time calibration apparatus for an intelligent wristwatch, specifically referring to fig. 2, where the apparatus includes:

the obtaining module 21 is configured to obtain pointer information of a pointer when the pointer appears at a preset position;

the identification module 22 is configured to identify a pointer type of the pointer according to the pointer information and a correspondence between the pointer information and the pointer type that is established in advance;

the determining module 23 is configured to determine, according to the pointer type and the preset position, a current pointer time corresponding to the pointer type;

the judging module 24 is used for judging whether the pointer time is consistent with the corresponding part of the RTC time of the clock chip, and if not, the adjusting module is triggered;

and an adjusting module 25 for controlling the gear box to rotate correspondingly to adjust the pointer so that the pointer time is consistent with the corresponding part of the RTC time.

It should be noted that the time calibration device of the intelligent wristwatch provided in the embodiment has the same beneficial effects as the time calibration method of the intelligent wristwatch provided in the embodiment, and for the specific description of the time calibration method of the intelligent wristwatch related in the embodiment, please refer to the embodiment, which is not repeated herein.

On the basis of the above embodiment, referring to fig. 3, an embodiment of the present invention further provides an intelligent wristwatch, including a collector 31 disposed at a preset position of a dial, a processor 32 connected to the collector 31, and a controller 33 connected to the processor 32, wherein:

the collector 31 is used for collecting pointer information of a pointer when the pointer appears at a preset position;

the processor 32 is configured to identify a pointer type of the pointer according to the pointer information and a pre-established correspondence between the pointer information and the pointer type, determine a current pointer time corresponding to the pointer type according to the pointer type and a preset position, determine whether the pointer time is consistent with a corresponding portion of an RTC time of the clock chip, and generate an adjustment instruction if the pointer time is not consistent with the corresponding portion of the RTC time of the clock chip;

and the controller 33 is used for controlling the gear box to correspondingly rotate according to the adjusting instruction so as to adjust the pointer, so that the pointer time is consistent with the corresponding part of the RTC time.

It should be noted that, in this embodiment, a preset position may be determined on the dial in advance, and a collector 31 is disposed at the preset position, since the pointer will pass through the preset position during the rotation process, the collector 31 disposed at the preset position can collect the pointer information of the corresponding pointer when the pointer (the hour pointer and/or the minute pointer and/or the second pointer) rotates to the preset position, and send the pointer information to the processor 32, the processor 32 can further identify the pointer type of the pointer according to the pointer information and the corresponding relationship between the pointer information and the pointer type established in advance, where the pointer type is the hour pointer, the minute pointer or the second pointer, the processor 32 can further determine the current pointer time corresponding to the pointer type according to the determined pointer type and the preset position, for example, the preset position is the position corresponding to the number 12 on the dial, and the pointer type is minute pointer, the current pointer time corresponding to the pointer type is 0 minute, the RTC time of the clock chip is acquired at this time, the pointer time is calibrated by taking the RTC time as an alignment, if the pointer time is not consistent with the corresponding part of the RTC time, the processor 32 generates an adjusting instruction, and the controller 33 controls the gear box in the intelligent wristwatch to correspondingly rotate according to the adjusting instruction so as to adjust the pointer, so that the pointer time is consistent with the corresponding part of the RTC time. For example, the current pointer time is 0 minutes, the RTC time is 0: and 58 minutes is the part corresponding to the minute hand, and at this time, the minute hand is faster by two seconds, so that the gear part corresponding to the minute hand in the gear box can be controlled by the controller to perform reverse adjustment, so that the minute hand time after adjustment is 58 minutes and the minute hand time in the RTC time are kept consistent.

In addition, in order to improve the calibration accuracy in practical application, the preset positions are not limited to one, but may also be multiple, and multiple corresponding collectors may also be provided, that is, the pointer information of the pointers appearing at multiple preset positions may be collected, the pointer time may be determined according to the pointer type and the corresponding preset position, and then the corresponding pointer may be calibrated according to the RTC time, so as to improve the calibration accuracy.

Furthermore, when a plurality of pointers of the intelligent wristwatch are provided, coatings with different characteristics are arranged on each pointer; the pointer information is the characteristic information of the corresponding pointer surface coating.

Specifically, the hand of the intelligent wristwatch in the present embodiment may be plural, for example, including the hour hand and the minute hand, or including the hour hand, the minute hand and the second hand, and when the hand in the intelligent wristwatch is plural, in order to distinguish the respective hands, coatings having different characteristics may be applied to the respective hands so as to identify the corresponding hand category based on different characteristic information.

Furthermore, each pointer is provided with a coating with different colors;

the characteristic information is spectral information, and the collector 31 includes a spectral sensor.

Specifically, in this embodiment, the spectral information of the coating layer on the pointer appearing at the preset position may be collected by the spectral sensor, so that the processor 32 identifies the corresponding pointer type according to the spectral information collected by the spectral sensor and the pre-established correspondence between the spectral information and the pointer type, so as to perform the subsequent calibration process.

Furthermore, coatings in different shapes are arranged on each pointer;

the characteristic information is shape information, and the collector 31 includes a shape recognition sensor.

Of course, in addition to setting the coating on each pointer to a coating of a different color, the shape of the coating may also be set, that is, the coating on each pointer is shaped differently, so as to further identify the corresponding pointer according to the shape information of each coating. Accordingly, the collector 31 in this embodiment may adopt a shape recognition sensor, for example, it may be implemented by an image recognition sensor, and by collecting shape information of a coating layer on a pointer currently appearing at a preset position, the processor 32 can identify a pointer type of the corresponding pointer according to the shape information and a correspondence between the shape information and the pointer type established in advance, so as to perform subsequent calibration.

In addition, it should be noted that, when a plurality of hands are provided in the smart wristwatch and each hand shares a rotating shaft, the corresponding hand may overlap at a certain time, for example, at the position of the numeral 12, the three hands of the hour hand, the minute hand and the second hand overlap every 12 hours, and the minute hand and the second hand overlap every 1 hour, so if the preset position is set to the position corresponding to the numeral 12, there may be a certain time that the minute hand and the second hand overlap, or the three hands overlap every hour, minute and second, and at this time, in order to be able to identify the coating characteristic information on the hand located at the lower layer, in this embodiment, a hollow-out groove may be provided in the upper layer hand in each hand in advance, and when the respective hands overlap, the coating on the hand located at the lower layer may be exposed from the hollow-out groove at the upper layer, so that the corresponding characteristic information is acquired. In the embodiment, a hollow groove is formed in the pointer located on the upper layer, so that when the pointer is overlapped with the pointer located on the lower layer, the coating layer arranged on the pointer located on the lower layer is exposed from the hollow groove.

For example, when the intelligent wristwatch includes only an hour hand and a minute hand, if the minute hand is located at the lower layer of the hour hand, a hollow-out groove may be provided at a position on the hour hand corresponding to a coating on the minute hand, that is, when the hour hand coincides with the minute hand, the coating on the minute hand may be exposed through the hollow-out groove, so that characteristic information of the coating is collected, as shown in fig. 4 and 5, specifically, 11 indicates a dial, 12 indicates the hour hand, 13 indicates the minute hand, 14 indicates a spectral sensor, 15 indicates a coating provided on the hour hand 12, 16 indicates a hollow-out groove provided on the hour hand 12, and 17 indicates a coating provided on the minute hand 13. When the intelligent wristwatch comprises three hour-minute-second hands, if the minute hand is positioned at the lower layer of the hour hand and the second hand is positioned at the lower layer of the minute hand, a hollow groove can be formed in the position, different from the coating on the hand, of the minute hand, and the position of the hollow groove corresponds to the position of the coating on the second hand, so that when the minute hand and the second hand are superposed, the coating on the second hand can be exposed from the hollow groove on the minute hand.
