[0030] With the continuous advancement of technology, wearable electronic devices such as smart watches are increasingly favored by consumers due to their portability and versatility. These wearable electronic devices integrate various sensors, functional modules and various algorithms to achieve multiple functions such as health monitoring, sports tracking, communication and interconnection.

[0031] However, the various functions of such wearable electronic devices (for example, the collection, monitoring, and recording of motion data) are often separated at the beginning of development, and developers need to manually associate the various functions. When developers develop, maintain, or transplant such associated functions, it takes a lot of time and the error rate is high. In addition, the reliability of manually associating the various functions is also low, which will further reduce the accuracy of wearable electronic devices in monitoring exercise time.

[0032] In view of this, the motion monitoring system provided in an embodiment of the present application includes a FreeRTOS operating system and an RTC module. The FreeRTOS operating system includes a first thread, which is used to obtain motion data collected by the motion sensor when the motion sensor of the wearable electronic device sends a first interrupt signal; and when the RTC module sends a second interrupt signal, determine the total motion time, and package the motion data generated within the total motion time to generate a motion record; and the RTC module is coupled to the wearable electronic device, and is used to send a second interrupt signal to the wearable electronic device at a preset time interval.

[0033] The following will be combined Figure 1 For an explanation of a motion monitoring system 10 provided in one embodiment of the present application, see Figure 1 , Figure 1 is a schematic diagram of the structure of a motion monitoring system 10 according to an embodiment of the present application. The motion monitoring system 10 can be applied to wearable electronic devices, such as Figure 1As shown, the motion monitoring system 10 may include a FreeRTOS operating system 100 and an RTC module 130; wherein the FreeRTOS operating system 100 includes a first thread 110, and the first thread 110 is used to obtain motion data collected by the motion sensor when the motion sensor of the wearable electronic device sends a first interrupt signal; and when the RTC module 130 sends a second interrupt signal, determine the total motion time, and package the motion data generated within the total motion time to generate a motion record; and the RTC module 130 is coupled to the wearable electronic device, and is used to send a second interrupt signal to the wearable electronic device at a preset time interval.

[0034] In this embodiment, the wearable electronic device to be applied by the motion monitoring system 10 provided in the embodiment of the present application can be a smart watch, a mobile phone, a tablet computer, a desktop, a laptop, a handheld computer, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, and a cellular phone, a personal digital assistant (PDA), an augmented reality (AR)\virtual reality (VR) device, a media player, a television and other devices. The embodiment of the present application does not impose any special restrictions on the specific form of the wearable electronic device. In the embodiment of the present application, the structure of the wearable electronic device can be a smart watch with a motion monitoring function that can be worn on the user's wrist.

[0035] In this embodiment, the FreeRTOS operating system 100 is an open source real-time operating system (RTOS) developed by Richard Barry, originally as an open source alternative to the VxWorks operating system, and is intended to provide scalability and reliability for resource-constrained embedded systems (e.g., microcontroller units and smart watches). The multi-tasking thread feature of the FreeRTOS operating system 100 can be used to create multiple threads to perform different functional tasks. For example, a first thread 110 (which can be named sport_thread) can be created in the FreeRTOS operating system 100 to perform a motion monitoring task.

[0036] In addition, the RTC (Real-Time Clock) module can be used as a task scheduler, which allows the user to define a time interval (ie, a preset time interval) and execute a task after the time interval ends.

[0037] In one embodiment, the RTC module 130 includes a second interrupt pin 131, which is coupled to a processor of the wearable electronic device and is used to send a second interrupt signal to the processor at a preset time interval to wake up the processor.

[0038] In this embodiment, the preset time interval can be defined as 20 seconds, and the task to be completed by the RTC module 130 is defined as waking up the processor of the wearable electronic device, then the RTC module 130 can send a second interrupt signal to the processor of the wearable electronic device every 20 seconds to wake up the processor. The time interval can be set according to actual needs, and this application is not limited here.

[0039] In one embodiment, the FreeRTOS operating system 100 also includes a second thread 120 (which can be named ui_thread), and the second thread 120 is used to display the motion data collected by the motion sensor in a preset first interface of the display screen of the wearable electronic device when the RTC module 130 sends a second interrupt signal.

[0040] In this embodiment, the first thread 110 is a thread for performing motion monitoring in the FreeRTOS operating system 100. The first thread 110 can be activated in an event-based manner, and the first thread 110 can record the exercise duration of the user wearing the wearable electronic device, and call the algorithm of each motion sensor in the wearable electronic device to calculate the reading of each motion sensor to obtain motion data and motion records.

[0041] In addition, the second thread 120 is a thread for executing display tasks in the FreeRTOS operating system 100. The second thread 120 is responsible for regularly updating the graphical user interface (GUI), including redrawing graphic elements, processing animation effects, etc., to maintain the real-time and smoothness of the interface; the second thread 120 is also used to respond to user interactions such as touch events and button clicks, and perform corresponding operations, such as navigating menus, switching views, etc.; the second thread 120 is also used to manage GUI-related resources, such as images, fonts, and animations, to ensure that they can be quickly loaded and rendered when needed.

[0042] Among them, GUI is a computer user interface that uses graphical elements (such as windows, icons, buttons and menus) to replace the traditional text command interface. The graphical interface allows the user to interact with the computer system through visual elements and user interaction, rather than relying on keyboard input commands. The GUI can be made through an embedded graphics library. In this embodiment, LVGL can be used to make multiple GUIs, wherein LVGL (Light and Versatile Graphical Library) is an open source GUI library designed specifically for embedded systems. It is designed to provide high performance, low memory consumption and easy-to-use graphical interfaces, which are very suitable for resource-constrained devices such as microcontroller units and smart watches.

[0043] In this embodiment, the motion monitoring system provided in the embodiment of the present application realizes the collection, monitoring, recording and display of motion data through the thread communication mechanism of the open source FreeRTOS operating system, without the need for developers to manually associate these functions. This not only saves developers the time required to develop, maintain or transplant associated functions, but also reduces the error rate during development, thereby improving the reliability of the motion monitoring function of wearable electronic devices, and further improving the accuracy of wearable electronic devices in monitoring exercise time.

[0044] Specifically, Figure 2 FIG. 1 shows a workflow diagram of the first thread 110 according to an embodiment of the present application. Figure 2 As shown, the first thread 110 may perform the following steps:

[0045] Step S201, monitor whether the motion sensor sends a first interrupt signal. If yes, proceed to step S203.

[0046] Step S202, monitoring whether the RTC module 130 sends a second interrupt signal. If yes, proceed to step S206.

[0047] Step S203: acquiring motion data collected by the motion sensor.

[0048] Step S204 , storing the motion data in a preset buffer 140 .

[0049] Step S205: determining whether an abnormal motion event occurs based on the motion data collected by the motion sensor.

[0050] Step S206, determining the total exercise time, and packaging the exercise data generated during the total exercise time to generate an exercise record.

[0051] In this embodiment, in addition to executing the motion monitoring function, the first thread 110 can also be used to determine whether an abnormal motion event occurs based on the motion data collected by the motion sensor.

[0052] Specifically, the first thread 110 may include multiple modules to perform the above steps. In one embodiment, the first thread 110 includes a first monitoring module 111, a second monitoring module 112, a data acquisition module 113, a storage module 114, an anomaly detection module 115 and a motion monitoring module 116; wherein the first monitoring module 111 is used to monitor whether the motion sensor sends a first interrupt signal; the second monitoring module 112 is used to monitor whether the RTC module 130 sends a second interrupt signal; the data acquisition module 113 is used to obtain the motion data collected by the motion sensor when the first monitoring module 111 determines that the motion sensor sends a first interrupt signal; the storage module 114 is used to store the motion data in a preset buffer 140; the anomaly detection module 115 is used to determine whether a motion abnormality event occurs based on the motion data collected by the motion sensor; and the motion monitoring module 116 is used to determine the total motion time when the second monitoring module 112 determines that the RTC module 130 sends a second interrupt signal, and package the motion data generated within the total motion time to generate a motion record.

[0053] In this embodiment, when the first monitoring module 111 monitors that the motion sensor is interrupted (sends a first interrupt signal), the data acquisition module 113 can use the driver to read the sensor reading from the built-in motion sensor of the wearable electronic device, and use the algorithm to calculate the sensor reading to obtain motion data. The motion data may include the number of steps, exercise duration, exercise mileage, offset, number of running laps, etc.

[0054] The storage module 114 can temporarily store the motion data in the buffer 140 built into the motion monitoring system 10, and the abnormality detection module 115 can perform abnormality detection based on the motion data to determine whether an abnormal motion event occurs. For example, when the motion duration is greater than a preset threshold, the abnormality detection module 115 can determine that an excessive motion event occurs. The abnormality detection module 115 can send the detected abnormal motion event to the second thread 120, so that the second thread 120 displays the abnormal motion event in real time when executing the display task.

[0055] In addition, when the second monitoring module 112 monitors the second interrupt signal sent by the RTC module 130, the motion monitoring module 116 can accumulate the motion time to determine the total motion time, and read the motion data stored in the buffer 140 at the same time, and package the motion data in the total motion time according to the private protocol to generate a motion record. The motion monitoring module 116 can send the motion data and the motion record to the second thread 120, so that the second thread 120 displays the motion data and the motion record in real time when executing the display task.

[0056] The specific working process of the second thread 120 will be described below with reference to the accompanying drawings. Figure 3 is a workflow diagram of the second thread 120 according to an embodiment of the present application, such as Figure 3 As shown, the second thread 120 may perform the following steps:

[0057] Step S301, monitoring whether the first thread 110 detects an abnormal motion event. If yes, proceed to step S303.

[0058] Step S302, monitoring whether the RTC module 130 sends a second interrupt signal. If yes, proceed to step S304.

[0059] Step S303, waking up the display screen of the wearable electronic device.

[0060] Step S304, whether the display screen is in a bright screen state. If yes, proceed to step S305; if no, return to step S302.

[0061] Step S305: displaying the motion data collected by the motion sensor in a preset first interface of the display screen.

[0062] Step S306: displaying the abnormal motion event in a preset second interface of the display screen.

[0063] In this embodiment, the wearable electronic device may include a display screen, which may have a sleep function and can automatically turn off the screen when not used for a long time.

[0064] Specifically, the second thread 120 may include multiple modules to perform the above steps. In one embodiment, the second thread 120 includes a third monitoring module 121, a fourth monitoring module 122, a screen wake-up module 123, a screen state determination module 124, a motion data display module 125, and an abnormal event display module 126; wherein the third monitoring module 121 is used to monitor whether the first thread 110 detects an abnormal motion event; the fourth monitoring module 122 is used to monitor whether the RTC module 130 sends a second interrupt signal; the screen wake-up module 123 is used to wake up the display screen of the wearable electronic device when the third monitoring module 121 determines that the first thread 110 detects an abnormal motion event; the screen state determination module 124 is used to determine whether the display screen is in a bright screen state when the fourth monitoring module 122 determines that the RTC module 130 sends a second interrupt signal; the motion data display module 125 is used to display the motion data collected by the motion sensor in the preset first interface of the display screen when the display screen is in the bright screen state; and the abnormal event display module 126 is used to display the abnormal motion event in the preset second interface of the display screen after the screen wake-up module 123 wakes up the display screen.

[0065] In this embodiment, the screen status determination module 124 can determine whether the display screen is in the screen-on state when the fourth monitoring module 122 determines that the RTC module 130 sends a second interrupt signal; and enter the sleep state when the display screen is in the screen-off state, and the second thread 120 only has the third monitoring module 121 and the fourth monitoring module 122 continue to monitor external events at this time, thereby reducing overall power consumption; when the display screen is in the screen-on state, motion data is read from the cache 140, and the motion data is transmitted to the first interface of the display screen for refresh display.

[0066] In addition, when the third monitoring module 121 monitors that the first thread 110 detects an abnormal motion event, the screen wake-up module 123 activates the display screen regardless of whether the display screen is in a bright screen state, and transmits the abnormal motion event to the second interface of the display screen for refreshing the display.

[0067] Through the motion monitoring system 10 provided in the embodiment of the present application, the open source code FreeRTOS operating system 100 and LVGL are used to monitor and display motion data, and the threads of the FreeRTOS operating system 100 and the secure communication between threads are fully utilized. The processing, monitoring, and display of motion data all use independent threads to ensure the real-time data collection and the security of display. Specifically, the processing and monitoring of motion data include real-time collection, data monitoring, and data preservation, and the display of motion data includes real-time GUI display of motion data, which satisfies the real-time data collection and the timeliness of display; at the same time, the high-precision RTC module 130 is used to record the motion time with high precision, which solves the problem of inaccurate motion time caused by data collection or display delay, and the RTC module 130 can trigger the GUI outside the thread to achieve accurate refresh display, save the use of system timers, and reduce overall power consumption.

[0068] In addition, the various functions of the existing motion monitoring method based on wearable electronic devices (for example, the collection, display, storage, etc. of motion data) are often split and not effectively associated. When developing, maintaining and transplanting corresponding functions, the workload is often large, and the error rate is also high, and a large amount of manpower and time are required to develop the implementation method of the whole set of functions; and when using the motion monitoring system 10 provided by the embodiment of the present application, by utilizing the multi-tasking and thread communication mechanism of the FreeRTOS operating system 100, the real-time collection, monitoring, recording, display and preservation of motion data are realized, and there is no need for the developer to manually associate these functions, which can not only save the developer the time required for developing, maintaining or transplanting the associated functions, but also reduce the error rate during development, thereby improving the reliability of the motion monitoring function of the wearable electronic device, and then improving the accuracy of the monitoring of the motion time of the wearable electronic device. It should be understood that although the motion monitoring system 10 is based on the FreeRTOS system and the LVGL graphics library, the motion monitoring system 10 may not be limited to the FreeRTOS system and the LVGL graphics library, as long as the operating system has a multi-tasking and thread communication mechanism, it can be transplanted.

[0069] In one embodiment, the FreeRTOS operating system 100 is used to allocate a memory space 150 , and the memory space 150 is used to store motion data collected by the motion sensor and motion records acquired by the first thread 110 .

[0070] In this embodiment, when the first thread 110 of the FreeRTOS operating system 100 monitors the first interrupt signal, it can be determined that the user wearing the wearable electronic device starts to exercise. At this time, the FreeRTOS operating system 100 can dynamically apply for memory to allocate memory space 150.

[0071] In addition, the FreeRTOS operating system 100 can also be used to initialize the memory space 150 before storing motion data in the memory space 150 .

[0072] In this embodiment, the FreeRTOS operating system 100 can formulate data structures of various motion types, and grid the applied memory according to the data structure for normalizing data storage and subsequent calculation of the file offset of the current record.

[0073] In one embodiment, the FreeRTOS operating system 100 is also used to detect whether there is a pre-stored motion record in the memory space 150 before storing the motion record obtained by the first thread 110 in the memory space 150, and when there is a pre-stored motion record in the memory space 150, update the pre-stored motion record based on the motion record obtained by the first thread 110.

[0074] In this embodiment, the FreeRTOS operating system 100 may continuously read the motion data stored in the buffer 140 at a preset time interval, and store the motion data in the memory space 150 .

[0075] In addition, when the user exits exercise, the FreeRTOS operating system 100 can detect whether there is a pre-stored exercise record in the memory space 150 (for example, whether an exercise record for the day has been created). If there is no pre-stored exercise record, the FreeRTOS operating system 100 can create an exercise record based on the exercise data in the memory space 150; if there is a pre-stored exercise record in the memory space 150, the pre-stored exercise record can be updated based on the exercise record obtained by the first thread 110.

[0076] Specifically, the sports records can be spliced ​​according to the date and the type of sports. For example, the running lap information in the sports record obtained by the first thread 110 can be spliced ​​at the end of the created sports record, and the data header content of the sports record can be updated. The data header content can record the sports data such as the sports duration, sports mileage, offset, running laps, etc.; or, the sports records corresponding to the same type of sports (running, cycling, yoga, etc.) can be spliced ​​together, and the same type of sports can include only one sports record file in one day.

[0077] In addition, you can also upload exercise records to other apps or sports to further save storage resources.

[0078] In this way, motion records are stored by dynamically applying for memory, which solves the problem of excessive fixed memory usage and increased power consumption caused by frequent reading and writing of flash.
