Detailed Description
In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
At present, wearable devices (such as smart watches, smart bracelets and the like) are popular in the market, and the smart watches, the smart bracelets and the like realize multifunctional wearable devices through a built-in intelligent system, a smart phone system and a network, and have the functions of receiving and calling, sending and receiving short messages, photographing and the like. Because the functions are complete and the carrying is very easy, the multifunctional portable electric toothbrush is widely favored by consumers.
Wearable equipment not only can be used for the user to carry out daily time and look over, can also be used to functions such as motion monitoring, sleep monitoring, health monitoring, and these functions need rely on time information. Therefore, for wearable devices, its time information will be especially important. At present, for the calibration of the time of the wearable device, the smart watch is mainly connected with the external device, then the external device synchronizes the time of the smart watch with the wearable device, and the wearable device performs time calibration according to the time information of the external device. For example, after the smart watch and the mobile phone are connected in a pairing manner, the mobile phone can transmit time to the smart watch through a bluetooth channel established between the smart watch and the mobile phone, and the time is transmitted to the smart watch at variable time in the connection process to be corrected. However, in such a manner, the wearable device relies on an external device to calibrate the time, which is prone to cause the problem of inaccurate time, and thus affects the normal use of the wearable device.
In view of the above problems, the inventor provides a time calibration method, a time calibration device, a wearable device, and a storage medium provided in the embodiments of the present application, which can calibrate the time of a sleeping system according to the time of an operating system when the system is switched, and improve the time accuracy of the wearable device. . The specific time calibration method is described in detail in the following examples.
The following description is directed to an application environment applicable to the time calibration method provided in the embodiments of the present application.
In this embodiment, the operating system of the wearable device may include a first system and a second system. Operating systems rely on processors to perform operations. The first system and the second system are respectively operated in different processors. For example, a wearable device includes a first processor to run a first system and a second processor to run a second system.
Referring to fig. 1, fig. 1 is a schematic flow chart illustrating a time calibration method according to an embodiment of the present application. In a specific embodiment, the time calibration method is applied to the wearable device. The specific process of this embodiment will be described below by taking the wearable device as an example, and it is understood that the wearable device applied in this embodiment may be a bracelet, a watch, and the like, which is not limited herein. As will be described in detail with respect to the flow shown in fig. 1, the time calibration method may specifically include the following steps:
step S110: detecting a system switch event when an operating system of the wearable device is the second system.
In this embodiment of the application, since the operating system of the wearable device includes the first system and the second system, the operating system currently used by the wearable device may be the first system or the second system, which is not limited herein. When the operating system currently used by the wearable device is the first system, the second system may be in a sleep state, and when the operating system currently used by the wearable device is the second system, the first system may be in the sleep state or in an off state, which is not limited herein.
In some embodiments, the first system may be a primary system of the wearable device and the second system is a secondary system of the wearable device; alternatively, the first system may be a secondary system of the wearable device, and the second system may be a primary system of the wearable device. The main system can be an intelligent system, the sub-system can be a non-intelligent system, and the non-intelligent system can be used for displaying simple interfaces such as a dial plate, so that the power consumption can be smaller in the state of operating the sub-system. Optionally, one of the first processor and the second processor may be a Central Processing Unit (CPU), the other processor may be a Micro Control Unit (MCU), the main system may be run by the CPU, and the sub-system may be run by the MCU.
In this embodiment, it may be detected whether an operating system currently used by the wearable device is the first system or the second system, where when it is detected that the operating system currently used by the wearable device is the second system, it may be detected whether a system handover event occurs, that is, an event of switching to the first system, so that when the system handover occurs, a time of the second system is calibrated. It can be understood that, when the second system is running, the first system is in a sleep or off state, so that the running of the Real Time Clock (RTC) of the processor running the first system is affected, which causes a problem in the system Time of the first system, so that the Time of the second system can be calibrated when a system switch occurs.
In some embodiments, the system switch event may be a user-initiated trigger, for example, a user inputs a system switch command into the wearable device; the wearable device may also be triggered and generated when corresponding adjustment is met, for example, the second system is a secondary system, and the second system operates under a breath screen condition, and then a system switching event may be triggered and generated when the screen is on, so as to switch to the primary system, and for example, the second system is the primary system, and the first system operates under the breath screen condition, and then a system switching event may be triggered and generated when the screen is on, so as to switch to the first system. Of course, the specific scenario and manner of generating the system switching event may not be limited.
Step S120: and responding to the system switching event, switching the operating system of the wearable device from the second system to the first system, and calibrating the system time of the first system according to the time corresponding to the second processor.
In this embodiment of the application, when a system switching event is detected, the operating system of the wearable device may be switched from the second system to the first system in response to the system switching event, that is, the wearable device operates the first system. When the system is switched, because the first system does not operate before, the system time determined according to the RTC time of the first processor after the first system operates may be wrong, the second system is in an operating state, the RTC of the second processor corresponding to the second system keeps operating all the time, and the RTC corresponding to the second processor is relatively accurate, the system time of the first system can be calibrated according to the time corresponding to the second processor.
In some embodiments, the time corresponding to the second processor may include: RTC time of the second processor, or system time of the second system. It is understood that when the processor runs the system, the system time is synchronized with the RTC time of the processor, and then when the second system is in the running state, the system time of the second system is synchronized with the RTC time of the second processor, so that the system time of the first system can be calibrated according to any one of the system time of the second system and the RTC time of the second processor. Of course, after switching to operate the first system and calibrating the system time of the first system according to the time corresponding to the second processor, the RTC time of the first system is also synchronized with the calibrated system time of the first system.
In some embodiments, the second processor may be an MCU, the first processor may be a CPU, the second system may be a system running a simple program (a non-intelligent system), and the first system may be a system running a complex program (an intelligent system). Generally, the timing accuracy of the RTC of the MCU is higher than that of the RTC of the CPU, so that the corresponding time of the second processor is more accurate under the condition of operating the second system; when the second system is switched to the first system, due to the fact that the functions of time display, motion monitoring, sleep monitoring and the like need to be carried out according to the system time when the first system is operated, at the moment, the system time of the first system can be updated according to the time corresponding to the second processor, and therefore the time accuracy and the normal operation state of the wearable device are guaranteed.
In some embodiments, when switching from the second system to the first system, the second processor may send its corresponding time to the second processor, so that the first processor may calibrate the system time of the first system according to the received time corresponding to the second processor.
According to the time calibration method provided by the embodiment of the application, when the operating system of the wearable device is the second system, the system switching event is detected, the system switching event is responded, the operating system of the wearable device is switched from the second system to the first system, and the system time of the first system is calibrated according to the time corresponding to the second processor, so that the time of the dormant system is calibrated according to the time corresponding to the running processor when the system is switched, and the time accuracy of the wearable device is improved.
Referring to fig. 2, fig. 2 is a schematic flow chart illustrating a time calibration method according to another embodiment of the present application. The time calibration method is applied to the wearable device, and will be described in detail with respect to the flow shown in fig. 2, and the time calibration method may specifically include the following steps:
step S210: detecting a system switch event when an operating system of the wearable device is the second system.
In the embodiment of the present application, step S210 may refer to the contents of the foregoing embodiments, which are not described herein again.
Step S220: and responding to the system switching event, switching the operating system of the wearable device from the second system to the first system, and adding the time corresponding to the second processor to a target message.
In this embodiment, when the wearable device runs the second system, and when the system is detected, and the operating system of the wearable device is switched from the second system to the first system in response to a system switching event, the wearable device may add the system time of the second system to the target message. The target message is a communication message which needs to be sent to the first system by the second system, so that the first system can calibrate the system time according to the time carried in the target message.
In some embodiments, the target message may be a system handover message when performing a system handover, the system handover message may be used to instruct the first system to operate and complete the system handover, and the first system may calibrate the system time according to the time carried in the system handover message received during the system handover. Of course, the target message may also be other messages communicated between the second system and the first system, for example, the target message may be power consumption statistics of the second system, an operation time length of the second system, content information to be displayed when the first system operates, and the like.
Step S230: and sending the target message to the first system to instruct the first system to calibrate the system time of the first system according to the time corresponding to the second processor in the target message.
In this embodiment of the present application, after the second system obtains the target message, the second system may send the target message to the first system, so that the first system may calibrate the system time of the first system according to the time corresponding to the second processor in the target message.
In some embodiments, when the target message is a system handover message for system handover, after adding the time corresponding to the second processor to the system handover message, the wearable device may send the system handover message to the second system, so that the first system operates, complete the system handover, and calibrate the system time of the first system according to the time corresponding to the second processor in the system handover message. Specifically, the system switching message may be sent to the first processor by the second processor, and the first processor operates the first system after receiving the system switching message, and calibrates the system time of the first system according to the time corresponding to the second processor in the system switching message while completing the system switching.
In some embodiments, calibrating the system time of the first system according to the time corresponding to the second processor may include: and if the system time of the first system is different from the time corresponding to the second processor, updating the system time of the first system to the time corresponding to the second processor. It can be understood that, when a system switch occurs, the system time of the system which is not in operation is calibrated by using the time corresponding to the second processor of the currently operating system as a standard, so that the system time of the first system can be calibrated when the system time of the first system is different from the time corresponding to the second processor. Optionally, if the system time of the first system is different from the time corresponding to the second processor, the system time of the first system may be updated to the time corresponding to the second processor.
Optionally, if the system time of the first system is different from the time corresponding to the second processor, updating the system time of the first system to the time corresponding to the second processor may include: if the system time of the first system is later than the time corresponding to the second processor, updating the system time of the first system to the time corresponding to the second processor; and if the system time of the first system is earlier than the time corresponding to the second processor and the time difference between the system time of the first system and the time corresponding to the second processor is greater than a set threshold, updating the system time of the first system to the time corresponding to the second processor.
In this embodiment, when the system time of the first system is longer than the time corresponding to the second processor, for example, the system time of the first system is 10: 00, the system time of the second system and the RTC time of the second processor are 11: 00, the system time of the first system may be updated to the RTC time of the second processor or the system time of the second system. If the system time of the first system is earlier than the time corresponding to the second processor, the time difference between the two can be determined, and if the time difference is greater than the set threshold, the system time of the first system is updated to the time corresponding to the second processor, for example, the set threshold is 1 second, and if the system time of the first system is 10 o ' clock and the system time of the second system and the RTC time of the second processor are 9 o ' clock, 59 minutes and 58 seconds, the time difference between the system time of the first system and the time corresponding to the second processor is 2 seconds and is greater than the set threshold (1 second), and at this time, the system time of the first system is updated to 9 o ' clock, 59 minutes and 58 seconds.
In some embodiments, the communication protocol between the first processor and the second processor may employ a protobuf protocol, and the above system switch message may be locked by classId and messageId.
For example, referring to fig. 3, the time synchronization management unit of the first processor may register message monitoring, when a system handover event is detected, the second processor sends a system handover message (carrying a time corresponding to the second processor) to the message management unit of the first processor, the message management unit sends the system handover message to the time synchronization management unit, and the time synchronization management unit may obtain a time corresponding to the second processor carried in the system handover message, and then calibrate the system time of the first system according to the time corresponding to the second processor.
In some embodiments, the second processor may be an MCU, the first processor may be a CPU, the second system may be a system running a simple program (a non-intelligent system), and the first system may be a system running a complex program (an intelligent system). Usually, the accuracy of the RTC of the MCU is higher than that of the RTC of the CPU, and therefore, the time corresponding to the second processor is accurate when the second system is running. In some scenes, after the wearable device is turned off the screen for a certain time, the first processor is in a dormant state and enters a mode of the second processor, namely the first system is switched to the second system, so that the power consumption is saved; when a corresponding operation (for example, a screen is turned on or some applications are opened) is detected, the mode of the first processor is entered, that is, the second system is switched to the first system, because the accuracy of the RTC of the MCU is higher than that of the RTC of the CPU, the time corresponding to the second processor can be used as a parameter to be put into the system switching message, and the first processor monitors the system switching message and calibrates the system time of the first system according to the time corresponding to the second processor in the system switching message when the system switching message is monitored. Specifically, when the time corresponding to the second processor in the system switching message is legal and meets a specified condition, the system time of the first system may be updated to the time corresponding to the second processor. Wherein, time legal means that the time is not later than a specified time, for example, not later than 1/1970; the specified conditions mean: if the system time of the first system is later than the time corresponding to the second processor, or the system time of the first system is earlier than the time corresponding to the second processor, and the time difference between the system time of the first system and the time corresponding to the second processor is greater than the set threshold.
According to the time calibration method provided by the embodiment of the application, when the operating system of the wearable device is the second system, a system switching event is detected, the system switching event is responded, the operating system of the wearable device is switched from the second system to the first system, the time corresponding to the second processor is added into the target message, and then the system switching message is sent to the first system to indicate the first system to calibrate the system time of the first system according to the time corresponding to the second processor, so that the time of the dormant system is calibrated according to the time corresponding to the running processor when the system is switched, and the time accuracy of the wearable device is improved.
Referring to fig. 4, fig. 4 is a schematic flow chart illustrating a time calibration method according to another embodiment of the present application. The time calibration method is applied to the wearable device, and the wearable device comprises a first processor and a second processor, wherein the first processor is used for operating a first system, the second processor is used for operating a second system, the first processor is a central processing unit, and the second processor is a micro control unit. As will be described in detail with respect to the flow shown in fig. 4, the time calibration method may specifically include the following steps:
step S310: detecting a system switch event when an operating system of the wearable device is the second system.
Step S320: and responding to the system switching event, switching the operating system of the wearable device from the second system to the first system, and calibrating the system time of the first system according to the time corresponding to the second processor.
In the embodiment of the present application, step S310 and step S320 may refer to the contents of the foregoing embodiments, and are not described herein again.
Step S330: when the operating system of the wearable device is the first system and the wearable device is connected with other terminals, calibrating the system time of the first system according to the time information of the other terminals.
In this embodiment, when the first processor is a central processing unit and the second processor is a micro control unit, the second system may be a system (non-intelligent system) for running a simple program, and the first system may be a system (intelligent system) for running a complex program. When the operating system of the wearable device is the second system, the second processor operating the second system is an MCU, and the MCU cannot update the system time of the wearable device according to external data; when the operating system of the wearable device is the first system, the CPU runs the first system, and at this time, the CPU can acquire time from the outside to calibrate the system time.
In this embodiment, when the operating system of the wearable device is the first system, if the wearable device is connected to another terminal, the system time of the first system may be calibrated according to the time information of the other terminal.
In some embodiments, in the process that the wearable device can be in pairing connection with other terminals, the first processor can acquire time information of the wearable device from the other terminals and then calibrate the system time of the first system according to the time information of the other terminals; the wearable device may also acquire time information from other terminals when reconnecting with the other terminals, and then calibrate the system time of the first system according to the time information of the other terminals.
Optionally, the system time of the first system may be updated to the time of the other terminal when the system time of the first system is later than the time of the other terminal, or the system time of the first system is earlier than the time of the other terminal, and a time difference between the system time of the first system and the time of the other terminal is greater than a first threshold.
Step S340: and when the wearable device is disconnected from the other terminals, calibrating the system time of the first system according to the network time.
In this embodiment of the application, when the wearable device runs the first system by using the first processor, if the wearable device is disconnected from other terminals, the network time may also be acquired, and the system time of the first system is calibrated. Optionally, the system time of the first system may be updated to the time of the other terminal when the system time of the first system is later than the acquired network time, or the system time of the first system is earlier than the acquired network time, and a time difference between the system time of the first system and the acquired network time is greater than a second threshold.
In some embodiments, in the case that the wearable device runs the first system by using the first processor, the network time may be immediately acquired to calibrate the system time of the first system when the wearable device is disconnected from other terminals; after the wearable device is disconnected from other terminals, the network time can be immediately acquired to calibrate the system time of the first system when the network where the wearable device is located changes, and synchronization of the network time is realized.
In some embodiments, in a case where the wearable device operates the first system by using the first processor and is disconnected from other terminals, the wearable device may also acquire the network time through the network at preset time intervals, and then calibrate the system time of the first system. The specific value of the preset time interval may not be limited, and may be, for example, 5 minutes, 10 minutes, 30 minutes, 60 minutes, or the like.
Step S350: when the operating system of the wearable device is the first system and the system time of the first system is updated, calibrating the system time of the second system according to the system time of the first system.
In this embodiment of the application, when the operating system of the wearable device is the first operating system, that is, when the CPU runs the first operating system, calibration of the system time of the first operating system is performed according to the external time, and if the system time of the first operating system is updated at this time, calibration of the system time of the second system may be performed according to the system time of the first system, so as to ensure that the system time of the second system is also synchronized with the external time.
In some embodiments, when the wearable device is turned on for the first time or brought back to factory, the first processor runs the first system, and since the RTCs of the first processor and the second processor are not running after the wearable device is powered off, at this time, the system times of the first system and the second system are inaccurate, the first processor may acquire time from the outside and set the time as the system time of the first system, or set the system time of the first system according to a user operation. Also, the system time and time zone of the first system may be synchronized to the second system to keep the system time of the two systems consistent.
