[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for explaining the relevant application and not for limiting the application. Furthermore, it should be noted that, for ease of description, only the parts related to the relevant application are shown in the accompanying drawings.

[0022] Currently, smart mobile terminals can support motion detection. For example, in related technologies, motion states can be determined by calculating the probability values ​​of candidate motion states and related confidence information. These technologies can be widely used on mobile platforms, and their main applications include motion-assisted geofencing, motion-assisted Wi-Fi scanning optimization, distracted pedestrian detection, and health monitoring. Common motion states include walking, running, cycling, riding in a motor vehicle, and remaining stationary.

[0023] However, current motion state recognition algorithms are generally quite complex, and these algorithms are usually resident applications of SMEs, which greatly increases the power consumption of SMEs in low-power scenarios, thus affecting the power-saving performance of smart mobile terminals.

[0024] To address the aforementioned issues, in the embodiments of this application, the electronic device can determine the detection period corresponding to the detection target; within the detection period, a motion ratio parameter is determined according to a preset time interval; and the motion state result corresponding to the detection target is determined based on the motion ratio parameter. This reduces power consumption and improves the energy-saving performance of the electronic device.

[0025] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0026] Figure 1 This is a schematic diagram of the implementation process of the motion state detection method proposed in the embodiments of this application. Figure 1 ,like Figure 1 As shown in the embodiments of this application, the method for detecting motion state by an electronic device may include the following steps:

[0027] Step 101: Determine the detection cycle corresponding to the detection target.

[0028] In the embodiments of this application, the electronic device may first determine the detection cycle corresponding to the detection target.

[0029] It should be noted that, in the embodiments of this application, the electronic device can be any electronic device with communication and storage functions, such as: tablet computer, mobile phone, e-reader, remote control, personal computer (PC), laptop computer, in-vehicle electronic device, internet TV, wearable electronic device, personal digital assistant (PDA), portable media player (PMP), navigation device, and other electronic devices and electronic equipment.

[0030] It should be noted that, in the embodiments of this application, the detection target refers to different types of motion states; for example, the detection target can be stationary, moving, or undergoing large-amplitude motion; it can also be motion states such as walking, running, cycling, or riding in a motor vehicle.

[0031] Furthermore, in the embodiments of this application, the detection period corresponds to the detection target, and the detection period is the time information required to determine the motion state result of the detection target.

[0032] For example, in the embodiments of this application, the detection targets are S1, S2, ..., Sn; and their respective detection periods can be T1, T2, ..., Tn.

[0033] Furthermore, in embodiments of this application, the electronic device can determine at least one detection cycle corresponding to at least one detection target; and then sort the at least one detection cycle to determine the detection order of at least one detection target.

[0034] In other words, in the embodiments of this application, the electronic device can simultaneously determine at least one detection target and determine the detection order of at least one detection target according to the respective detection cycle of the at least one detection target.

[0035] For example, in an embodiment of this application, at least one detection target includes stationary, moving, and large-amplitude moving targets; wherein, the detection period corresponding to stationary is T1, the detection period corresponding to moving is T2, and the detection period corresponding to large-amplitude moving targets is T3; the electronic device can determine the detection order of the three detection targets, stationary, moving, and large-amplitude moving targets, by sorting T1, T2, and T3.

[0036] It is understood that, in the embodiments of this application, the detection order is the order in which at least one detection target is detected.

[0037] For example, in the embodiments of this application, the detection order of the three detection targets, namely, stationary, moving, and large-amplitude movement, can be large-amplitude movement, moving, and stationary; that is, large-amplitude movement is detected first, then moving, and finally stationary.

[0038] In one embodiment of this application, when the electronic device sorts at least one detection cycle to determine the detection order of at least one detection target, it can sort at least one detection cycle in ascending order to obtain a sorting result; thereby determining the detection order of at least one detection target based on the sorting result.

[0039] For example, in the embodiments of this application, the detection targets are S1, S2, ..., Sn; their respective detection periods can be T1, T2, ..., Tn; by sorting T1, T2, ..., Tn in ascending order, the sorting result is T1<=T2<=...<=Tn, thereby determining the detection order of these n detection targets as S1, S2, ..., Sn.

[0040] Step 102: Within the detection cycle, determine the motion ratio parameter according to the preset time interval.

[0041] In the embodiments of this application, the electronic device can determine the motion ratio parameter within the detection period according to a preset time interval after determining the detection period corresponding to the detection target.

[0042] It should be noted that in the embodiments of this application, the motion ratio parameter is obtained according to a preset time interval; the value of the preset time interval is not specifically limited in this application; for example, if the preset time interval is 1 second, then the motion ratio parameter is calculated once every 1 second.

[0043] Furthermore, in some embodiments of this application, when the electronic device determines the motion ratio parameter according to a preset time interval, it can acquire acceleration data through an accelerometer; then determine the counter value based on the acceleration data; and then determine the motion ratio parameter according to the output data rate of the accelerometer and the counter value according to the preset time interval.

[0044] Furthermore, in some embodiments of this application, when the electronic device determines the counter value based on the acceleration data, it can first initialize the counter value; then compare the acceleration data of each frame with a preset threshold to obtain a comparison result; if the comparison result is that the acceleration data is greater than the preset threshold, the counter value is incremented by 1.

[0045] Furthermore, in some embodiments of this application, when the electronic device determines the motion ratio parameter based on the output data rate of the accelerometer and the counter value, it can perform a division operation on the counter value and the output data rate to obtain the motion ratio parameter.

[0046] Therefore, in the embodiments of this application, the entire motion state detection calculation process only involves some simple operations of adders and dividers. For example, the counter value is determined by the operation of the adder, and the motion ratio parameter can be determined by the operation of the divider. The calculation process is greatly simplified, which can effectively reduce power consumption and provide great convenience for hardware to implement motion state detection calculation.

[0047] Step 103: Determine the motion state result corresponding to the detected target based on the motion ratio parameter.

[0048] In the embodiments of this application, the electronic device can determine the motion ratio parameter according to a preset time interval within the detection cycle, and then determine the motion state result corresponding to the detection target based on the motion ratio parameter.

[0049] It should be noted that, in the embodiments of this application, the motion state result can be used to determine whether the electronic device is in the motion state corresponding to the detection target; for example, if the detection target is a large-amplitude motion, and the electronic device determines that it is a large-amplitude motion by obtaining the motion ratio parameter in the detection cycle corresponding to the large-amplitude motion, then the motion state result is a large-amplitude motion; and if it is determined that it is not a large-amplitude motion, then the motion state result is a non-large-amplitude motion.

[0050] Furthermore, in some embodiments of this application, the electronic device can determine at least one motion state result corresponding to at least one detection target in sequence according to the motion ratio parameter, based on the detection sequence.

[0051] In other words, in the embodiments of this application, when the electronic device is in different detection cycles in sequence according to the detection order, it only needs to continue to calculate the motion ratio parameter according to the preset time interval to obtain the motion state result of the corresponding detection target in different detection cycles.

[0052] Furthermore, in some embodiments of this application, during the process of sequentially determining the motion state result corresponding to at least one detection target, if the detection duration reaches the first detection cycle in at least one detection period, the motion state result of the first detection target corresponding to the first detection cycle is obtained; wherein, the first detection cycle is the smallest detection cycle in at least one detection cycle; if the detection duration reaches the second detection cycle in at least one detection period, the motion state result of the second detection target corresponding to the second detection cycle is obtained; wherein, the second detection cycle is greater than the first detection cycle; the detection process continues to be executed until the detection duration reaches the maximum detection cycle in at least one detection period, and the motion state result of the third detection target corresponding to the maximum detection cycle is obtained.

[0053] For example, in the embodiments of this application, the detection targets include S1, S2, and S3; the detection period corresponding to S1 is 2 seconds, the detection period corresponding to S2 is 4 seconds, and the detection period corresponding to S3 is 6 seconds; the electronic device detects the motion state in the order of detection of S1, S2, and S3. When the detection time reaches 2 seconds, the motion state of S1 is obtained, and the detection process continues to be executed (the motion ratio parameter is obtained according to the preset time interval). When the detection time reaches 4 seconds, the motion state of S2 is obtained, and the detection process continues to be executed. When the detection time reaches 6 seconds, the motion state of S3 is obtained.

[0054] Furthermore, in the embodiments of this application, a motion ratio calculation unit can be set up. The motion ratio calculation unit can determine the motion ratio parameter according to a preset time interval. Thus, when the electronic device detects different detection targets, the motion ratio calculation unit can be set to execute cyclically to obtain the motion state results of different detection targets.

[0055] For example, in an embodiment of this application, the electronic device detects targets S1 and S2. The detection cycle of S1 is 2 seconds and the detection cycle of S2 is 4 seconds. The motion ratio calculation unit calculates the motion ratio parameter once every 1 second. Thus, the motion ratio calculation unit can be set to execute the cycle twice to obtain the motion state of S1. Based on this, the cycle can be repeated twice more to obtain the motion state of S2.

[0056] Furthermore, in some embodiments of this application, when the electronic device determines the motion state result corresponding to the detected target based on the motion ratio parameter, it can determine the motion state result based on the motion ratio parameter and a preset state threshold.

[0057] It should be noted that, in the embodiments of this application, when the motion ratio parameter is greater than or equal to the preset state threshold, it can be determined that the electronic device conforms to the motion state of the detection target; for example, if the detection target is running and the preset state threshold corresponding to running is 4, in the detection cycle corresponding to running, if the obtained motion ratio parameter is greater than or equal to 4, then the motion state result is determined to be running.

[0058] It is understood that in the embodiments of this application, the preset state threshold can be set freely, for example, different preset state thresholds can be set according to different detection targets.

[0059] Furthermore, in some embodiments of this application, when the electronic device determines the motion state result based on the motion ratio parameter, it can also determine the motion state result based on the motion ratio parameter and a preset time threshold.

[0060] It should be noted that, in the embodiments of this application, the motion state result can also be determined according to a preset time threshold. For example, during the detection process, if the detection duration is greater than or equal to the preset time threshold, the motion ratio parameter is greater than or equal to the corresponding preset state threshold within the detection duration. That is, when the motion ratio parameter is greater than or equal to the preset state threshold for a duration greater than or equal to the preset time threshold, it can be determined that the electronic device conforms to the motion state corresponding to the detection target.

[0061] Furthermore, in the embodiments of this application, the preset time threshold can also be freely set, for example, different preset time thresholds can be set according to different detection targets.

[0062] For example, in an embodiment of this application, the detection target is a large-amplitude movement, the preset state threshold corresponding to the large-amplitude movement is 5, and the preset time threshold is 8 seconds; within the detection period of the large-amplitude movement, the movement ratio parameter remains at 5 within 8 seconds, that is, it is greater than or equal to the preset state threshold, then the movement state result can be determined to be a large-amplitude movement.

[0063] Figure 2 This is a schematic diagram of the implementation process of the motion state detection method proposed in the embodiments of this application. Figure 2 ,like Figure 2 As shown, the method for an electronic device to determine a motion ratio parameter according to a preset time interval may include the following steps:

[0064] Step 201: Acquire acceleration data using an accelerometer.

[0065] In some embodiments of this application, the electronic device determines the motion ratio parameter according to a preset time interval; in some embodiments of this application, the electronic device may first acquire acceleration data through an accelerometer.

[0066] It should be noted that, in the embodiments of this application, an acceleration sensor (ACC) may be deployed in the electronic device to acquire acceleration data; for example, the acceleration sensor may be a triaxial acceleration sensor.

[0067] Furthermore, in the embodiments of this application, the electronic device can cache the acceleration data in batches of a specified size after acquiring acceleration data through the accelerometer.

[0068] Step 202: Determine the counter value based on the acceleration data.

[0069] In the embodiments of this application, after the electronic device acquires acceleration data through the accelerometer, it can determine the counter value based on the acceleration data.

[0070] It should be noted that, in the embodiments of this application, the electronic device can obtain the cached acceleration data from the batch to determine the counter value.

[0071] Furthermore, in the embodiments of this application, for low-power scenarios, the electronic device does not need to determine the motion state in real time. Therefore, after acquiring the acceleration data, the acceleration data can be cached first, and then the cached acceleration data can be used to determine the motion state of the electronic device. This can greatly reduce the power consumption of the electronic device and effectively reduce the power consumption of the electronic device in low-power scenarios.

[0072] Furthermore, in some embodiments of this application, when the electronic device determines the counter value based on the acceleration data, it can first initialize the counter value; then compare the acceleration data of each frame with a preset threshold to obtain a comparison result; if the comparison result is that the acceleration data is greater than the preset threshold, the counter value is incremented by 1.

[0073] It is understood that in the embodiments of this application, if the comparison result is that the acceleration data is less than or equal to a preset threshold, the counter value will not change.

[0074] For example, in an embodiment of this application, the preset threshold is 1; the electronic device reads the cached acceleration data, and at the same time sets the counter to zero (initializes), and then starts to calculate. The acceleration data of each frame is compared with 1. If the acceleration data of the frame is greater than 1, the counter value is incremented by 1. If the acceleration data of the frame is less than or equal to 1, no processing is performed and the counter value remains unchanged.

[0075] In addition, in the embodiments of this application, the electronic device determines the counter value by comparing the acceleration data of each frame, while the motion ratio parameter is calculated according to a preset time interval. Assuming that the preset time interval is 1 second, and the acceleration data of 1 second contains 6 frames of acceleration data, the electronic device may calculate the motion ratio parameter once within 1 second, but determine the counter value 6 times.

[0076] Step 203: Determine the motion ratio parameter according to the output data rate of the accelerometer and the counter value at a preset time interval.

[0077] In the embodiments of this application, after the electronic device determines the counter value based on the acceleration data, it can determine the motion ratio parameter according to the output data rate of the acceleration sensor and the counter value at a preset time interval.

[0078] It should be noted that, in the embodiments of this application, the Output Data Rate (ODR) is a parameter of the accelerometer.

[0079] Furthermore, in the embodiments of this application, the specific value of the preset time interval is not limited. For example, the preset time interval can be 1 second, so that when the electronic device detects the motion state, it can calculate the motion ratio parameter once every 1 second.

[0080] Furthermore, in the embodiments of this application, when the electronic device determines the motion ratio parameter based on the output data rate of the accelerometer and the counter value, it can perform a division operation on the counter value and the output data rate to obtain the motion ratio parameter.

[0081] For example, in an embodiment of this application, the motion ratio parameter = counter value / ODR.

[0082] Furthermore, in the embodiments of this application, after determining the motion ratio parameter, the electronic device can store the motion ratio parameter and initialize the counter.

[0083] In summary, in the embodiments of this application, the entire motion detection calculation process involves only adders and dividers, as well as some simple operations. This achieves extremely low power consumption while also facilitating hardware implementation of the algorithm. Furthermore, the calculation cycle, based on a preset time interval, reduces redundancy in hardware and software design and enhances scalability. This application can be extended to any number of detection cycles for different motion states, and to motion state recognition with any detection cycle. For example, if the detection targets are motion state 1 and motion state 2, where the detection cycle for motion state 1 is 2 seconds and the detection cycle for motion state 2 is 4 seconds, and the preset time interval is 1 second, then the motion ratio calculation unit, which calculates the motion ratio in 1-second units, can be executed once to obtain the detection of motion state 1, and then repeated twice to complete the detection of motion state 2.

[0084] This application provides a method for detecting motion state. An electronic device determines a detection period corresponding to a detection target; within the detection period, a motion ratio parameter is determined at preset time intervals; and the motion state result corresponding to the detection target is determined based on the motion ratio parameter. Therefore, in this embodiment, after determining the detection period of the detection target, the electronic device can calculate the motion ratio parameter at preset time intervals within the detection period, thereby directly determining the motion state result corresponding to the detection target based on the motion ratio parameter. Since the motion ratio parameter only involves simple operations such as division, the entire motion state detection process can be greatly simplified, thereby reducing the power consumption of the electronic device and improving energy-saving performance.

[0085] Based on the above embodiments, in another embodiment of this application, for example, the electronic device is a mobile terminal device, and the motion state detection method can be applied to the low power consumption scenario of the mobile terminal device. Figure 3 This is a schematic diagram of the implementation process of the motion state detection method proposed in the embodiments of this application. Figure 3 ,like Figure 3 As shown, in the low-power scenario of the mobile terminal device, the mobile terminal device can use the motion ratio calculation unit to calculate the motion ratio parameter in units of 1 second (preset time interval) in any detection cycle (step 301). After obtaining the motion ratio parameter, it is determined whether the detection time has reached the detection cycle (step 302). If the determination result is no, step 301 is continued. If the determination result is yes, the motion state result is determined according to the motion ratio parameter, and the current detection ends (step 303).

[0086] Furthermore, in the embodiments of this application, for step 301, namely the method of the motion ratio calculation unit calculating the motion ratio parameter, Figure 4 This is a schematic diagram of the implementation process of the motion state detection method proposed in the embodiments of this application. Figure 4 ,like Figure 4 As shown, the motion ratio calculation unit can first acquire acceleration sensor data (step 301a), then determine whether the acceleration sensor data is greater than a preset threshold (step 301b). If it is less than or equal to the preset threshold, the counter value remains unchanged (step 301c). If it is greater than the preset threshold, the counter value is incremented by 1 (step 301d). Then, the motion ratio parameter is calculated every second based on the counter value and ODR, and the motion ratio parameter is stored after it is calculated.

[0087] It should be noted that, in the embodiments of this application, the motion ratio calculation unit is implemented in hardware, which can identify multiple motion states without waking up the SME, greatly reducing the number of times the SME needs to be woken up in daily use. For example, in smart scenarios based on motion recognition, existing solutions require the SME to be frequently woken up and run one or more detection algorithms to identify whether the user is in a stationary, walking, or other motion state. Using a hardware motion ratio calculation unit can achieve the same motion detection purpose without waking up the SME. The resulting technical effects include: on the one hand, the SME does not need to be frequently woken up; on the other hand, it is no longer necessary to run complex motion state detection algorithms in the SME.

[0088] Furthermore, in the embodiments of this application, the electronic device can determine the motion state for different detection targets; the detection target refers to different types of motion states; for example, the detection target can be stationary, moving, or undergoing large-amplitude movement; it can also be motion states such as walking, running, cycling, or riding in a motor vehicle.

[0089] Furthermore, in the embodiments of this application, different detection targets correspond to different detection cycles; the detection cycle is the time information required to determine the motion state result of the detection target.

[0090] For example, in the embodiments of this application, the detection targets are S1, S2, ..., Sn; and their respective detection periods can be T1, T2, ..., Tn.

[0091] Furthermore, in embodiments of this application, the electronic device can determine at least one detection cycle corresponding to at least one detection target; and then sort the at least one detection cycle to determine the detection order of at least one detection target.

[0092] In other words, in the embodiments of this application, the electronic device can simultaneously determine at least one detection target and determine the detection order of at least one detection target according to the respective detection cycle of the at least one detection target.

[0093] For example, in an embodiment of this application, at least one detection target includes stationary, moving, and large-amplitude moving targets; wherein, the detection period corresponding to stationary is T1, the detection period corresponding to moving is T2, and the detection period corresponding to large-amplitude moving targets is T3; the electronic device can determine the detection order of the three detection targets, stationary, moving, and large-amplitude moving targets, by sorting T1, T2, and T3.

[0094] It is understood that, in the embodiments of this application, the detection order is the order in which at least one detection target is detected.

[0095] For example, in the embodiments of this application, the detection order of the three detection targets, namely, stationary, moving, and large-amplitude movement, can be large-amplitude movement, moving, and stationary; that is, large-amplitude movement is detected first, then moving, and finally stationary.

[0096] In one embodiment of this application, when the electronic device sorts at least one detection cycle to determine the detection order of at least one detection target, it can sort at least one detection cycle in ascending order to obtain a sorting result; thereby determining the detection order of at least one detection target based on the sorting result.

[0097] For example, in the embodiments of this application, the detection targets are S1, S2, ..., Sn; their respective detection periods can be T1, T2, ..., Tn; by sorting T1, T2, ..., Tn in ascending order, the sorting result is T1<=T2<=...<=Tn, thereby determining the detection order of these n detection targets as S1, S2, ..., Sn.

[0098] Furthermore, in the embodiments of this application, the electronic device determines the motion ratio parameter according to a preset time interval during the detection cycle. For example, if the preset time interval is 1 second, the motion ratio parameter is calculated once every 1 second.

[0099] Furthermore, in some embodiments of this application, when the electronic device determines the motion ratio parameter according to a preset time interval, it can acquire acceleration data through an accelerometer; then determine the counter value based on the acceleration data; and then determine the motion ratio parameter according to the output data rate of the accelerometer and the counter value according to the preset time interval.

[0100] Furthermore, in the embodiments of this application, the electronic device can cache the acceleration data in batches of a specified size after acquiring acceleration data through the accelerometer.

[0101] Furthermore, in an embodiment of this application, the electronic device can obtain cached acceleration data from the batch to determine the counter value.

[0102] It should be noted that, in the embodiments of this application, for low-power scenarios, the electronic device does not need to determine the motion state in real time. Therefore, after acquiring the acceleration data, the acceleration data can be cached first, and then the cached acceleration data can be used to determine the motion state of the electronic device. This can greatly reduce the power consumption of the electronic device and effectively reduce the power consumption of the electronic device in low-power scenarios.

[0103] Furthermore, in some embodiments of this application, when the electronic device determines the counter value based on the acceleration data, it can first initialize the counter value; then compare the acceleration data of each frame with a preset threshold to obtain a comparison result; if the comparison result is that the acceleration data is greater than the preset threshold, the counter value is incremented by 1.

[0104] Furthermore, in some embodiments of this application, when the electronic device determines the motion ratio parameter based on the output data rate of the accelerometer and the counter value, it can perform a division operation on the counter value and the output data rate to obtain the motion ratio parameter.

[0105] It should be noted that in the embodiments of this application, the electronic device determines the counter value by comparing the acceleration data of each frame, while the motion ratio parameter is calculated according to a preset time interval. Assuming that the preset time interval is 1 second, and the acceleration data of 1 second contains 6 frames of acceleration data, the electronic device may calculate the motion ratio parameter once within 1 second, but determine the counter value 6 times.

[0106] Therefore, in the embodiments of this application, the entire motion state detection calculation process only involves some simple operations of adders and dividers. For example, the counter value is determined by the operation of the adder, and the motion ratio parameter can be determined by the operation of the divider. The calculation process is greatly simplified, which can effectively reduce power consumption and provide great convenience for hardware to implement motion state detection calculation.

[0107] Furthermore, in the embodiments of this application, the electronic device can determine the motion state result corresponding to the detected target based on the motion ratio parameter.

[0108] It should be noted that, in the embodiments of this application, the motion state result can be used to determine whether the electronic device is in the motion state corresponding to the detection target; for example, if the detection target is a large-amplitude motion, and the electronic device is determined to be in a large-amplitude motion by obtaining the motion ratio parameter during the detection cycle corresponding to the large-amplitude motion, then the motion state result is a large-amplitude motion; and if it is determined that the electronic device is not in a large-amplitude motion, then the motion state result is a non-large-amplitude motion.

[0109] Furthermore, in some embodiments of this application, the electronic device can determine at least one motion state result corresponding to at least one detection target in sequence according to the motion ratio parameter, based on the detection sequence.

[0110] In other words, in the embodiments of this application, when the electronic device is in different detection cycles in sequence according to the detection order, it only needs to continue to calculate the motion ratio parameter according to the preset time interval to obtain the motion state result of the corresponding detection target in different detection cycles.

[0111] Furthermore, in some embodiments of this application, during the process of sequentially determining the motion state result corresponding to at least one detection target, if the detection duration reaches the first detection cycle in at least one detection period, the motion state result of the first detection target corresponding to the first detection cycle is obtained; wherein, the first detection cycle is the smallest detection cycle in at least one detection cycle; if the detection duration reaches the second detection cycle in at least one detection period, the motion state result of the second detection target corresponding to the second detection cycle is obtained; wherein, the second detection cycle is greater than the first detection cycle; the detection process continues to be executed until the detection duration reaches the maximum detection cycle in at least one detection period, and the motion state result of the third detection target corresponding to the maximum detection cycle is obtained.

[0112] For example, in the embodiments of this application, the detection targets include S1, S2, and S3; the detection period corresponding to S1 is 2 seconds, the detection period corresponding to S2 is 4 seconds, and the detection period corresponding to S3 is 6 seconds; the electronic device detects the motion state in the order of detection of S1, S2, and S3. When the detection time reaches 2 seconds, the motion state of S1 is obtained, and the detection process continues to be executed (the motion ratio parameter is obtained according to the preset time interval). When the detection time reaches 4 seconds, the motion state of S2 is obtained, and the detection process continues to be executed. When the detection time reaches 6 seconds, the motion state of S3 is obtained.

[0113] Furthermore, in the embodiments of this application, a motion ratio calculation unit can be set up. The motion ratio calculation unit can determine the motion ratio parameter according to a preset time interval. Thus, when the electronic device detects different detection targets, the motion ratio calculation unit can be set to execute cyclically to obtain the motion state results of different detection targets.

[0114] For example, in an embodiment of this application, the electronic device detects targets S1 and S2. The detection cycle of S1 is 2 seconds and the detection cycle of S2 is 4 seconds. The motion ratio calculation unit calculates the motion ratio parameter once every 1 second. Thus, the motion ratio calculation unit can be set to execute the cycle twice to obtain the motion state of S1. Based on this, the cycle can be repeated twice more to obtain the motion state of S2.

[0115] Furthermore, in some embodiments of this application, when the electronic device determines the motion state result corresponding to the detected target based on the motion ratio parameter, it can determine the motion state result based on the motion ratio parameter and a preset state threshold.

[0116] It should be noted that, in the embodiments of this application, when the motion ratio parameter is greater than or equal to the preset state threshold, it can be determined that the electronic device conforms to the motion state of the detection target; for example, if the detection target is running and the preset state threshold corresponding to running is 4, in the detection cycle corresponding to running, if the obtained motion ratio parameter is greater than or equal to 4, then the motion state result is determined to be running.

[0117] It is understood that in the embodiments of this application, the preset state threshold can be set freely, for example, different preset state thresholds can be set according to different detection targets.

[0118] Furthermore, in some embodiments of this application, when the electronic device determines the motion state result based on the motion ratio parameter, it can also determine the motion state result based on the motion ratio parameter and a preset time threshold.

[0119] It should be noted that, in the embodiments of this application, the motion state result can also be determined according to a preset time threshold. For example, during the detection process, if the detection duration is greater than or equal to the preset time threshold, the motion ratio parameter is greater than or equal to the corresponding preset state threshold within the detection duration. That is, when the motion ratio parameter is greater than or equal to the preset state threshold for a duration greater than or equal to the preset time threshold, it can be determined that the electronic device conforms to the motion state corresponding to the detection target.

[0120] Furthermore, in the embodiments of this application, the preset time threshold can also be freely set, for example, different preset time thresholds can be set according to different detection targets.

[0121] For example, in an embodiment of this application, the detection target is a large-amplitude movement, the preset state threshold corresponding to the large-amplitude movement is 5, and the preset time threshold is 8 seconds; within the detection period of the large-amplitude movement, the movement ratio parameter remains at 5 within 8 seconds, that is, it is greater than or equal to the preset state threshold, then the movement state result can be determined to be a large-amplitude movement.

[0122] In summary, the calculation method using calculator values ​​and motion ratio parameters in the embodiments of this application simplifies the calculation process for motion state recognition, resulting in lower power consumption and simpler hardware and software design for SMEs. Furthermore, the easily expandable motion ratio calculation unit can support any number of motion states and detection cycles, making the hardware implementation of the algorithm simpler. Therefore, it is more suitable for use in low-power scenarios of electronic devices, improving power-saving performance.

[0123] This application provides a method for detecting motion state. An electronic device determines a detection period corresponding to a detection target; within the detection period, a motion ratio parameter is determined at preset time intervals; and the motion state result corresponding to the detection target is determined based on the motion ratio parameter. Therefore, in this embodiment, after determining the detection period of the detection target, the electronic device can calculate the motion ratio parameter at preset time intervals within the detection period, thereby directly determining the motion state result corresponding to the detection target based on the motion ratio parameter. Since the motion ratio parameter only involves simple operations such as division, the entire motion state detection process can be greatly simplified, thereby reducing the power consumption of the electronic device and improving energy-saving performance.
