Description

Technical Field

[0001] This application relates to the field of equipment status determination, and more specifically, to a method, apparatus, storage medium, and electronic device for determining equipment status. Background Technology

[0002] During the cooking process, whether the cooking equipment can maintain normal operation is related to whether the cooking task can be completed smoothly. Therefore, it is very important to accurately judge the operating status of the cooking equipment. Judging the operating status of the cooking equipment includes judging the status of the cooking equipment lid, such as whether the top cover is closed tightly and whether the side door is closed tightly. If the judgment of the status of the cooking equipment lid is not timely or accurate, it will affect the execution of the cooking task and may even lead to accidents.

[0003] In related technologies, the method for judging the state of the lid of cooking equipment is to use a special lid opening and closing detection mechanism, such as a lid opening and closing detection mechanism that includes a magnetic reed switch. However, the lid opening and closing detection mechanism has a complex structure, and the connection structure will age after the equipment has been used for a long time, affecting the accuracy of the lid opening and closing detection. At the same time, traditional detection methods cannot determine whether the lid is in motion or stationary. For example, if the lid is currently in the process of closing, it will result in an error in judging the state of the equipment lid.

[0004] There is currently no effective solution to the problem that related technologies require complex opening and closing detection mechanisms to detect the state of cooking equipment lids, and that the detection results are inaccurate. Summary of the Invention

[0005] This application provides a method, apparatus, storage medium, and electronic device for determining the state of a device, in order to solve the problem in the related art that a complex opening and closing lid detection mechanism is required to detect the state of the cooking device lid, and the detection results of the cooking device lid state are inaccurate.

[0006] According to one aspect of this application, a method for determining the state of a device is provided. The method includes: acquiring target data transmitted by a first wireless module via a second wireless module, wherein the second wireless module is disposed on the main body of the target device, and the first wireless module is disposed on the cover of the target device; within a time period, counting the number of times the target data is acquired corresponding to multiple identical first time intervals; comparing the magnitude relationship between at least two acquisition counts to obtain a set of first comparison results, wherein the set of first comparison results includes at least one first comparison result; and determining the state of the cover based on the set of first comparison results. That is, by comparing the number of times the second wireless module acquires target data in the same time interval, obtaining comparison results, and determining the state of the cover based on the comparison results, the method achieves the effect of quickly detecting the state of the cover of a cooking device.

[0007] Optionally, determining the state of the cover based on a set of first comparison results includes: if at least one first comparison result indicates that the subsequent acquisition count is not equal to the previous acquisition count, determining that the cover is currently in motion; if all first comparison results indicate that the subsequent acquisition count is equal to the previous acquisition count, determining that the cover is currently in a stationary state. By comparing the acquisition counts, the changes in the acquisition counts are obtained, and the state of the cover is determined based on these changes, thereby improving the accuracy of determining the current state of the cover.

[0008] Optionally, determining that the cover is currently in motion when at least one first comparison result indicates that the subsequent acquisition count is not equal to the previous acquisition count includes: determining that the cover is moving in the closing direction when a set of first comparison results all indicate that the subsequent acquisition count is greater than or equal to the previous acquisition count; and determining that the cover is moving in the opening direction when a set of first comparison results all indicate that the subsequent acquisition count is less than or equal to the previous acquisition count. By determining the motion state of the equipment cover, a data foundation is laid for improving the accuracy of equipment cover status determination.

[0009] Optionally, after determining that the cover is currently in motion when at least one first comparison result indicates that the number of acquisitions in the subsequent acquisition is not equal to the number of acquisitions in the previous acquisition, the method further includes: comparing the magnitude relationship between the last acquisition count and a preset value to obtain a second comparison result; determining that the current state of the cover is a closed state when the cover moves in the closing direction and the second comparison result indicates that the last acquisition count is greater than or equal to the first preset value; determining that the current state of the cover is the same as the previously determined state when the cover moves in the closing direction and the second comparison result indicates that the last acquisition count is less than or equal to the first preset value; determining that the current state of the cover is an open state when the cover moves in the opening direction and the second comparison result indicates that the last acquisition count is less than or equal to the second preset value, wherein the first preset value is greater than the second preset value; and determining that the current state of the cover is the same as the previously determined state when the cover moves in the opening direction and the second comparison result indicates that the last acquisition count is greater than the second preset value. By combining the movement state of the cover and the number of acquisitions in the last time interval to determine the open / closed state of the cover, the method achieves the effect of accurately determining the state of the cover.

[0010] Optionally, after determining that the cover is currently stationary when all first comparison results indicate that the subsequent acquisition count is equal to the previous acquisition count, the method further includes: comparing the last acquisition count with a preset value to obtain a third comparison result; determining that the current state of the cover is closed when the third comparison result indicates that the last acquisition count is greater than or equal to the first preset value; determining that the current state of the cover is open when the third comparison result indicates that the last acquisition count is less than or equal to the second preset value, wherein the first preset value is greater than the second preset value; and determining that the current state of the cover is the same as the previously determined state when the third comparison result indicates that the last acquisition count is less than the first preset value and greater than the second preset value. By combining the movement state of the device cover and the acquisition count of the last time interval to determine the open / closed state of the cover, the method achieves the effect of accurately determining the state of the device cover.

[0011] Optionally, before determining the state of the cover based on a set of first comparison results, the method further includes: acquiring temperature data of the target device and determining the temperature range corresponding to the temperature data, wherein the frequency at which the second wireless module acquires the target data differs under different temperatures; when the temperature range corresponding to the temperature data is a first temperature range, acquiring a first preset value and a second preset value determined within the first temperature range; when the temperature range corresponding to the temperature data is a second temperature range, acquiring a first preset value and a second preset value determined within the second temperature range, wherein the lower limit of the second temperature range is equal to the upper limit of the first temperature range, the first preset value determined within the second temperature range is less than the first preset value determined within the first temperature range, and the second preset value determined within the second temperature range is less than the second preset value determined within the first temperature range; when the temperature range corresponding to the temperature data is a third temperature range, acquiring a first preset value and a second preset value determined within the third temperature range, wherein the upper limit of the third temperature range is equal to the lower limit of the first temperature range, the first preset value determined within the third temperature range is less than the first preset value determined within the first temperature range, and the second preset value determined within the third temperature range is less than the second preset value determined within the first temperature range. By adjusting the preset values ​​under different temperatures, the accuracy of the device cover state determination is avoided.

[0012] Optionally, before determining the state of the cover based on a set of first comparison results, the method further includes: within a first temperature range, counting the number of times the second wireless module acquires target data within multiple identical second time intervals in the covered state, and averaging the acquired counts to obtain a first target count; determining a first preset value based on the first target count; counting the number of times the second wireless module acquires target data within multiple identical second time intervals in the open state, and averaging the acquired counts to obtain a second target count; determining a second preset value based on the second target count, wherein the second time interval is the same as the first time interval; within a second temperature range, counting the number of times the second wireless module acquires target data within multiple identical second time intervals in the covered state, and averaging the acquired counts to obtain a second target count; determining a second preset value based on the second target count, wherein the second time interval is the same as the first time interval; The average of the three target counts is calculated to obtain the third target count. A first preset value is determined based on this third target count. Then, the average of the number of times the second wireless module acquires target data within multiple identical second time intervals in the open-cover state is calculated to obtain the fourth target count. A second preset value is determined based on this fourth target count. Within the third temperature range, the average of the number of times the second wireless module acquires target data within multiple identical second time intervals in the closed-cover state is calculated to obtain the fifth target count. A first preset value is determined based on this fifth target count. Similarly, the average of the number of times the second wireless module acquires target data within multiple identical second time intervals in the open-cover state is calculated to obtain the sixth target count. A second preset value is determined based on this sixth target count. By calculating the average value of the target data received within fixed time intervals, preset values ​​at different temperatures are determined, thus improving the accuracy of determining the device cover status.

[0013] According to another aspect of this application, a device for determining the state of a device is provided. The device includes: a first acquisition unit, configured to acquire target data transmitted by a first wireless module via a second wireless module, wherein the second wireless module is disposed on the main body of the target device and the first wireless module is disposed on the cover of the target device; a first statistics unit, configured to count the number of times the target data is acquired under multiple identical first time intervals within a time period; a first comparison unit, configured to compare the magnitude relationship between at least two acquisition counts to obtain a set of first comparison results, wherein the set of first comparison results includes at least one first comparison result; and a first determination unit, configured to determine the state of the cover based on the set of first comparison results.

[0014] According to another aspect of the present invention, a computer storage medium is also provided for storing a program, wherein the program, when running, controls the device where the computer storage medium is located to execute a device state determination method.

[0015] According to another aspect of the present invention, an electronic device is also provided, comprising a processor and a memory; the memory stores computer-readable instructions, and the processor is configured to execute the computer-readable instructions, wherein the computer-readable instructions, when executed, perform a device state determination method.

[0016] This application employs the following steps: A second wireless module acquires target data transmitted by a first wireless module, wherein the second wireless module is mounted on the main body of the target device, and the first wireless module is mounted on the cover of the target device; within a time period, the number of times the target data is acquired is counted for multiple identical first time intervals; the relationship between at least two acquisition counts is compared to obtain a set of first comparison results, wherein the set of first comparison results includes at least one first comparison result; the state of the cover is determined based on the set of first comparison results. This solves the problem in related technologies where a complex opening and closing cover detection mechanism is required to detect the state of the cooking device cover, and the detection results are inaccurate.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0023] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of this application described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0024] According to an embodiment of this application, a method for determining the status of a device is provided.

[0025] Figure 1 This is a flowchart of a device status determination method provided according to an embodiment of this application. For example... Figure 1 As shown, the method includes the following steps:

[0026] Step S102: Obtain the target data sent by the first wireless module through the second wireless module, wherein the second wireless module is installed on the main body of the target device and the first wireless module is installed on the cover of the target device.

[0027] Specifically, the second wireless module can be a reader, specifically a swept-frequency oscillator, which can be installed on the main body of the target device. The first wireless module can be a transponder with a preset fixed resonant frequency. The swept-frequency oscillator and the transponder can communicate using RFID (Radio Frequency Identification) technology. The swept-frequency oscillator can transmit radio frequency signals within a certain frequency range to the transponder at a preset frequency (e.g., once every 200ms) through an inductor coil. When the resonant frequency of the radio frequency signal transmitted by the swept-frequency oscillator is the same as the preset resonant frequency in the transponder, the swept-frequency oscillator receives the target data signal transmitted by the transponder, obtains the target data, and thus completes the wireless acquisition of the target data.

[0028] Step S104: Within a time period, count the number of times the target data is acquired under multiple identical first time intervals.

[0029] Specifically, the selected time period can be any consecutive time period, and a fixed time interval can be set within that time period to count the number of times the target data is obtained.

[0030] It should be noted that since 5 frames of data can be received in 250ms under normal cover conditions, a time period can be set to 1s, and each first time interval can be set to 250ms, resulting in 4 first time intervals T1 to T4. T1 can be the first time interval within the time period, and T4 can be the last time interval within the time period. The number of times the target data is acquired in each first time interval is counted. For example, T1 acquires the target data 2 times, T2 acquires the target data 3 times, T3 acquires the target data 3 times, and T4 acquires the target data 4 times.

[0031] Step S106: Compare the size relationship between at least two acquisition counts to obtain a set of first comparison results, wherein the set of first comparison results includes at least one first comparison result.

[0032] Specifically, after obtaining the number of times the target data was acquired in each first time interval, the acquisition counts corresponding to each first time interval can be compared to obtain the first comparison result of the number of times the target data was acquired.

[0033] For example, within a time period, T1 acquires 0 pieces of target data, T2 acquires 1 piece of target data, T3 acquires 2 pieces of target data, and T4 acquires 3 pieces of target data. The four acquisition counts can be compared to obtain a first comparison result. That is, a set of first submission results contains only one first comparison result, from which it can be seen that the number of acquisitions gradually increases. Alternatively, T1, T2, and T3 can be compared, and T2, T3, and T4 can be compared to obtain a set of first comparison results, from which it can be seen that the number of acquisitions gradually increases. Furthermore, T1 can be compared with T2, T2 with T3, and T3 with T4 to obtain a set of first comparison results, from which it can be seen that the number of acquisitions gradually increases. This embodiment does not limit the number of acquisitions extracted or the method of comparing the acquisition counts.

[0034] Step S108: Determine the state of the cover based on a set of first comparison results.

[0035] Specifically, after comparing the number of times the target data was acquired, the device cover status can be determined based on the comparison results. For example, if it is detected that T1 acquired 0 target data times, T2 acquired 0 target data times, T3 acquired 2 target data times, and T4 acquired 5 target data times, then by comparing T3 with T1 and T4 with T3, and noting that the number of acquisitions increases over time with a maximum of 5 acquisitions, the current status can be determined as closed. As another example, if it is detected that T1 acquired 4 target data times, T2 acquired 4 target data times, T3 acquired 3 target data times, and T4 acquired 1 target data time, then by comparing T3 with T1 and T4 with T3, and noting that the number of acquisitions decreases over time with a minimum of 1 acquisition, the current status can be determined as open.

[0036] The device status determination method provided in this application embodiment acquires target data sent by a first wireless module through a second wireless module. The second wireless module is disposed on the main body of the target device, and the first wireless module is disposed on the cover of the target device. Within a time period, the number of times the target data is acquired is counted for multiple identical first time intervals. The relationship between at least two acquisition counts is compared to obtain a set of first comparison results, wherein at least one first comparison result is included in the set of first comparison results. The status of the cover is determined based on the set of first comparison results. This solves the problem in related technologies where a complex opening and closing cover detection mechanism is required to detect the status of the cooking device cover, and the detection results are inaccurate. By comparing the number of times the second wireless module acquires target data in the same time interval, a comparison result is obtained, and the status of the cover is determined based on the comparison result, thereby achieving the effect of quickly detecting the status of the cooking device cover.

[0037] Optionally, in the device state determination method provided in the embodiments of this application, determining the state of the cover based on a set of first comparison results includes: determining that the cover is currently in motion when at least one first comparison result indicates that the subsequent acquisition count is not equal to the previous acquisition count; and determining that the cover is currently in a stationary state when all of a set of first comparison results indicate that the subsequent acquisition count is equal to the previous acquisition count.

[0038] It should be noted that if the first comparison result indicates that the number of times the next acquisition is not equal to the number of times the previous acquisition is, it means that the content of the first comparison result is that the number of times the next acquisition is not equal to the number of times the previous acquisition is. If the first comparison result indicates that the number of times the next acquisition is equal to the number of times the previous acquisition is, it means that the content of the first comparison result is that the number of times the next acquisition is equal to the number of times the previous acquisition is.

[0039] Specifically, the time required for data transmission between the sweep frequency oscillator and the transponder varies depending on the distance between the cover and the main body of the equipment. This results in a change in the number of times the sweep frequency oscillator receives the target data within the same time period. Therefore, the operating status of the cover can be determined based on the number of times the sweep frequency oscillator acquires the target data at multiple identical time intervals within a given time period.

[0040] For example, three identical time intervals T1 to T3 can be set within 1 second. If target data is acquired once in T1, once in T2, and twice in T3, since the number of times the target data is acquired in T1 and T2 is the same but different from that in T3, a first comparison result indicates that the number of times the target data is acquired in the later acquisition is not equal to the number of times the target data is acquired in the earlier acquisition. Therefore, it can be determined that the current cover is in motion. Alternatively, four identical time intervals T1 to T4 can be set within 1 second. If target data is acquired once in T1, once in T2, once in T3, and once in T4, since the number of times the target data is acquired in T1 to T4 is the same, a set of first comparison results all indicate that the number of times the target data is acquired in the later acquisition is equal to the number of times the target data is acquired in the earlier acquisition. Therefore, it can be determined that the current cover is in a stationary state. This embodiment improves the accuracy of determining the current state of the cover by observing the changes in the acquired target data and judging the state of the cover based on these changes.

[0041] Optionally, in the device state determination method provided in the embodiments of this application, determining that the cover is currently in motion when at least one first comparison result indicates that the number of subsequent acquisitions is not equal to the number of previous acquisitions includes: determining that the cover is moving in the closing direction when a set of first comparison results all indicate that the number of subsequent acquisitions is greater than or equal to the number of previous acquisitions; and determining that the cover is moving in the opening direction when a set of first comparison results all indicate that the number of subsequent acquisitions is less than or equal to the number of previous acquisitions.

[0042] Specifically, if the number of times the target data is acquired differs between two time intervals, the direction of the equipment cover's movement can be determined based on the data changes.

[0043] For example, four identical time intervals T1 to T4 can be set within 1 second, where T1 can be the first time interval and T4 can be the last time interval. If T1 acquires target data once, T2 acquires target data once, T3 acquires target data three times, and T4 acquires target data three times, then by comparison, since T1 and T2 are the same, T3 and T4 are the same, and T3 is different from T2, it can be determined that the cover is currently in motion. Since T3 acquires target data two more times than T2, it can be determined that the device is currently in a closed state. If T1 acquires target data four times, T2 acquires target data three times, T3 acquires target data once, and T4 acquires target data once, then the number of acquisitions decreases over time, and it can be determined that the device is currently in a closed state. This embodiment lays a data foundation for improving the accuracy of device cover status determination by judging the movement state of the device cover.

[0044] Optionally, in the device state determination method provided in the embodiments of this application, after determining that the cover is currently in a moving state when at least one first comparison result indicates that the number of acquisitions is not equal to the number of acquisitions previously, the method further includes: comparing the magnitude relationship between the last acquisition count and a preset value to obtain a second comparison result; determining that the current state of the cover is a closed state when the cover moves in the closing direction and the second comparison result indicates that the last acquisition count is greater than or equal to the first preset value; determining that the current state of the cover is the same as the previously determined state when the cover moves in the closing direction and the second comparison result indicates that the last acquisition count is less than the first preset value; determining that the current state of the cover is an open state when the cover moves in the opening direction and the second comparison result indicates that the last acquisition count is less than or equal to the second preset value, wherein the first preset value is greater than the second preset value; and determining that the current state of the cover is the same as the previously determined state when the cover moves in the opening direction and the second comparison result indicates that the last acquisition count is greater than the second preset value.

[0045] Specifically, when at least one first comparison result indicates that the number of acquisitions is not equal to the number of acquisitions in the previous acquisition, the current state of the device cover can be determined based on the direction of movement and the relationship between the last acquisition and a preset value. The first preset value can be used to determine the state of the cover when it is moving in the closing direction, and the second preset value can be used to determine the state of the cover when it is moving in the opening direction.

[0046] For example, Figure 2 This is a flowchart of an optional device status determination method provided according to an embodiment of this application, such as... Figure 2As shown, the time interval between every two frames of data transmission can be set to 50 ms first, and the number of data frames obtained is counted every 250 ms for one second. The first preset value can be 4, and the second preset value can be 2. At this time, the system judges the state of the device cover body, and obtains the number of data frame acquisitions T1 to T4. Among them, T1 is the number obtained within the first time interval, and T4 is the number obtained within the last time interval. At this time, judge the magnitude relationship among T1, T2, T3, and T4. When T1 = T2 < T3 < T4, it is judged that the device cover body is in the state of closing the cover. And when T4 = 5, it is judged that the device cover body is currently in the state of opening the cover. When T4 = 3, it is judged that the current state of the cover body is the same as the state determined in the previous time. When T1 = T2 > T3 > T4, it is judged that the device cover body is in the state of closing the cover. And when T4 = 0, it is judged that the device cover body is currently in the state of closing the cover. When T4 = 3, it is judged that the current state of the cover body is the same as the state determined in the previous time. In this embodiment, the opening and closing state of the cover body is determined by combining the motion state of the device cover body and the number of acquisitions in the last time interval, achieving the effect of accurately determining the state of the device cover body.

[0047] Optionally, in the method for judging the device state provided in the embodiment of the present application, after determining that the cover body is currently in a stationary state when a set of first comparison results all indicate that the number of acquisitions in the later time is equal to the number of acquisitions in the previous time, the method further includes: comparing the size relationship between the number of acquisitions in the last time and the preset value to obtain a third comparison result; when the third comparison result indicates that the number of acquisitions in the last time is greater than or equal to the first preset value, determining that the current state of the cover body is the state of closing the cover; when the third comparison result indicates that the number of acquisitions in the last time is less than or equal to the second preset value, determining that the current state of the cover body is the state of opening the cover, where the first preset value is greater than the second preset value; when the third comparison result indicates that the number of acquisitions in the last time is less than the first preset value and greater than the second preset value, determining that the current state of the cover body is the same as the state determined in the previous time.

[0048] Specifically, when there is at least one first comparison result indicating that the number of acquisitions in the later time is equal to the number of acquisitions in the previous time, the current state of the device cover body can be judged according to the size relationship between the number of acquisitions in the last time and the preset value. Among them, the first preset value can be used to judge whether the cover body is in the state of closing the cover, and the second preset value can be used to judge whether the cover body is in the state of opening the cover.

[0049] For example, the time interval between sending two data frames can be set to 50ms. The number of data frame acquisitions is counted every 250ms for one second. The first preset value can be 4, and the second preset value can be 2. At this time, the system determines the device cover state, obtaining four data frame acquisition quantities T1 to T4, where T1 is the number acquired in the first time interval, and T4 is the number acquired in the last time interval. Then, the relationship between T1, T2, T3, and T4 is determined. If T1 = T2 = T3 = T4, the device cover is determined to be stationary; if T4 = 4, the device cover is determined to be open; if T4 = 2, the device cover is determined to be closed; and if T4 = 3, the current state of the cover is determined to be the same as the previously determined state. This embodiment combines the device cover's movement state and the number of acquisitions in the last time interval to determine the open / closed state of the cover, achieving an accurate determination of the device cover state.

[0050] Optionally, in the device state determination method provided in this application embodiment, before determining the state of the cover based on a set of first comparison results, the method further includes: acquiring temperature data of the target device and determining the temperature range corresponding to the temperature data, wherein the frequency at which the second wireless module acquires the target data is different at different temperatures; when the temperature range corresponding to the temperature data is a first temperature range, acquiring a first preset value and a second preset value determined within the first temperature range; when the temperature range corresponding to the temperature data is a second temperature range, acquiring a first preset value and a second preset value determined within the second temperature range, wherein the lower limit of the second temperature range is equal to the upper limit of the first temperature range, the first preset value determined within the second temperature range is less than the first preset value determined within the first temperature range, and the second preset value determined within the second temperature range is less than the second preset value determined within the first temperature range; when the temperature range corresponding to the temperature data is a third temperature range, acquiring a first preset value and a second preset value determined within the third temperature range, wherein the upper limit of the third temperature range is equal to the lower limit of the first temperature range, the first preset value determined within the third temperature range is less than the first preset value determined within the first temperature range, and the second preset value determined within the third temperature range is less than the second preset value determined within the first temperature range.

[0051] Specifically, because the resonant capacitance value of the resonant circuit changes with temperature, it may cause variations in the operating frequency and chip sweep time. Therefore, temperature can affect the amount of target data acquired within a preset statistical time period, potentially leading to errors in determining the open / closed state of the target device. Thus, it is necessary to adjust the first and second preset values ​​accordingly based on temperature to eliminate detection errors caused by temperature factors that could lead to incorrect judgments about the open / closed state of the target device.

[0052] For example, the first temperature range can be a normal temperature environment, and the temperature range can be set to -5℃ to 70℃; the second temperature range can be a high temperature environment, and the temperature range can be set to greater than 75℃; the third temperature range can be a low temperature environment, and the temperature range can be set to less than -5℃. In a normal temperature environment, the first preset value can be 4 and the second preset value can be 2; in a high temperature environment, the first preset value can be 3 and the second preset value can be 0; in a low temperature environment, the first preset value can be 3 and the second preset value can be 1.

[0053] It should be noted that when the temperature is at the critical value between two temperature environments, the current environment needs to be determined as an abnormal temperature environment, and the first and second preset values ​​should be adjusted accordingly. For example, when the current temperature is -5℃, it is determined to be a low temperature state, and the first preset value can be 4 and the second preset value can be 2. When the current temperature is 70℃, it is determined to be a high temperature state, and the first preset value can be 3 and the second preset value can be 0. This embodiment achieves the effect of avoiding the influence of temperature on the accuracy of the determination of the device cover state by adjusting the preset values ​​at different temperatures.

[0054] Optionally, in the device state determination method provided in this application embodiment, before determining the state of the cover based on a set of first comparison results, the method further includes: within a first temperature range, counting the number of times the second wireless module acquires target data within multiple identical second time intervals in the closed state, and averaging the acquired number to obtain a first target number; determining a first preset value based on the first target number; counting the number of times the second wireless module acquires target data within multiple identical second time intervals in the open state, and averaging the acquired number to obtain a second target number; determining a second preset value based on the second target number, wherein the second time interval is the same as the first time interval; within a second temperature range, counting the number of times the second wireless module acquires target data within multiple identical second time intervals in the closed state. The number of times the second wireless module acquires target data in the open state within multiple identical second time intervals is counted, and the average of these counts is calculated to obtain the third target count. A first preset value is determined based on the third target count. The number of times the second wireless module acquires target data in the open state within multiple identical second time intervals is counted, and the average of these counts is calculated to obtain the fourth target count. A second preset value is determined based on the fourth target count. Within the third temperature range, the number of times the second wireless module acquires target data in the closed state within multiple identical second time intervals is counted, and the average of these counts is calculated to obtain the fifth target count. A first preset value is determined based on the fifth target count. The number of times the second wireless module acquires target data in the open state within multiple identical second time intervals is counted, and the average of these counts is calculated to obtain the sixth target count. A second preset value is determined based on the sixth target count.

[0055] Specifically, to better determine the first and second preset values ​​at different temperatures, the device can be tested at the corresponding temperatures to obtain the first and second preset values ​​at different temperatures. For example, the device can be placed in an environment of 50°C with the lid closed. At this point, target data is received, and the number of times the target data is acquired in multiple second time intervals is determined. The average value is then calculated and set as the preset value for the device with the lid closed under normal temperature conditions, thus obtaining the first preset value under normal temperature conditions. Simultaneously, the device can be placed in an open state, and the above operation can be repeated to obtain the second preset value under normal temperature conditions. Furthermore, the device can be placed in high-temperature and low-temperature environments to obtain the first and second preset values ​​under high-temperature and low-temperature conditions, respectively. This embodiment determines the preset values ​​at different temperatures by calculating the average value of the target data received within a fixed time interval, thereby improving the accuracy of determining the device lid state.
