It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.

In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only partial embodiments of the present application, but not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort shall fall within the protection scope of the present application.

It should be noted that the terms "first," "second," and the like in the description and claims of this application and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It should be understood that the data so used may be interchanged under appropriate circumstances such that embodiments of the application described herein may be used. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

According to an embodiment of the application, a method for judging a device state is provided.

Fig. 1 is a flowchart of a method for determining a device status according to an embodiment of the present disclosure. As shown in fig. 1, the method comprises the steps of:

step S102, obtaining target data sent by a first wireless module through a second wireless module, where the second wireless module is disposed on a main body of a target device, and the first wireless module is disposed on a cover of the target device.

Specifically, the second wireless module may be a reader, and specifically may be a Frequency sweep oscillator, and may be installed on a main body of the target device, the first wireless module may be a transponder whose resonant Frequency is a preset fixed value, the Frequency sweep oscillator and the transponder may communicate by using a Radio Frequency Identification (RFID) technology, the Frequency sweep oscillator may send a Radio Frequency signal having a Frequency within a certain range to the transponder through the inductance coil according to a preset Frequency (for example, sending the Radio Frequency signal every 200 ms), and when the resonant Frequency of the Radio Frequency signal sent by the Frequency sweep oscillator is the same as the preset resonant Frequency in the transponder, the Frequency sweep oscillator receives a target data signal sent in the transponder to obtain target data, thereby completing wireless acquisition of the target data.

And step S104, setting a statistical time length, and counting the acquisition times of the target data in the statistical time length.

Specifically, the set statistical duration may be any duration, and the number of times of acquiring the target data may be counted in the statistical duration, for example, the statistical duration may be set to 5s, and the number of times of acquiring the target data in 5s may be acquired.

And step S106, when the acquisition times of the target data in the statistical time length are more than or equal to a first preset time, determining that the current state of the cover body is the cover closing state.

Specifically, the time required for transmitting the target data is different between the cover opening state and the cover closing state, so that the times of acquiring the target data in the statistical duration can be recorded, and the opening and closing state of the cover body of the device can be judged according to the recorded acquisition times, wherein when the acquisition times are greater than or equal to a first preset time, the current state of the cover body can be determined to be the cover closing state. For example, the first preset number of times may be 5 times, and in a case that the number of times of acquiring the target data in the statistical time duration is 6 times, it may be determined that the current state of the cover body is the cover closing state.

And S108, when the acquisition times of the target data in the counting time length are less than or equal to a second preset time, determining that the current state of the cover body is an uncovering state, wherein the second preset time is less than the first preset time.

Specifically, the current state of the cover body may be determined to be the cover closing state when the number of times of acquisition is less than or equal to a second preset number of times. For example, the second preset number of times may be 2 times, and when the number of times of acquiring the target data in the statistical duration is 1 time, it may be determined that the current state of the lid body is the lid opening state.

Step S110, when the number of times of obtaining the target data in the statistical duration is smaller than the first preset number of times and larger than the second preset number of times, determining that the current state of the cover is the same as the state determined in the previous statistical duration.

Specifically, when the number of times of acquisition is greater than the second preset number of times and less than the first preset number of times, it may be determined that the current state of the lid is the same as the state determined within the last statistical time. For example, the first preset number of times may be 5 times, and the second preset number of times may be 2 times, and when the number of times of acquiring the target data in the statistical time duration is 4 times, it may be determined that the current state of the lid body is the same as the state determined in the previous statistical time duration, for example, the state determined in the previous statistical time duration is the lid opening, and the current state of the lid body determined in the present statistical period is also the lid opening.

According to the method for judging the equipment state provided by the embodiment of the application, target data sent by a first wireless module is obtained through a second wireless module, wherein the second wireless module is arranged on a main body of target equipment, and the first wireless module is arranged on a cover body of the target equipment; setting a statistical time length, and counting the acquisition times of the target data in the statistical time length; when the acquisition times of the target data in the counting time length are larger than or equal to a first preset time, determining that the current state of the cover body is a cover closing state; when the acquisition times of the target data in the counting time length are less than or equal to a second preset time, determining that the current state of the cover body is an uncovering state, wherein the second preset time is less than the first preset time; when the acquisition times of the target data in the statistical time length are smaller than the first preset times and larger than the second preset times, the current state of the cover body is determined to be the same as the state determined in the previous statistical time length, and the problems that a complex cover opening and closing detection mechanism needs to be arranged to detect the state of the cover body of the cooking equipment and the detection result of the state of the cover body of the cooking equipment is inaccurate in the related technology are solved. Through judging the number of times of receiving signals and judging the time two kinds of modes required by receiving the signals of the preset number of times in the preset time, the modification of the opening and closing judgment threshold value of the cover body of the cooking equipment is timely carried out under the condition of being influenced by the temperature, and the cover body state of the cooking equipment can be conveniently and accurately detected.

Optionally, in the method for determining a device status provided in the embodiment of the present application, the setting a statistical duration includes: acquiring temperature data of target equipment, and determining a temperature range corresponding to the temperature data, wherein the frequencies of the target data acquired by the second wireless module at different temperatures are different; when the temperature range corresponding to the temperature data is a first temperature range, determining the first time length as a statistical time length; when the temperature range corresponding to the temperature data is a second temperature range, determining a second time length as a statistical time length, wherein the lower limit of the second temperature range is equal to the upper limit of the first temperature range, and the second time length is greater than the first time length; and when the temperature range corresponding to the temperature data is a third temperature range, determining a third time length as a statistical time length, wherein the upper limit of the third temperature range is equal to the lower limit of the first temperature range, the third time length is greater than the first time length, and the second time length is different from the third time length.

Specifically, the resonant capacitance of the resonant circuit may change under different temperatures, which may cause a change in the passing frequency and a difference in the chip sweep time, so that the number of target data acquired within the statistical duration may change due to the temperature, which may cause an error in determining the open/close state of the target device. Therefore, the statistical time needs to be correspondingly adjusted according to different temperatures, so that the error judgment of the cover opening and closing state of the target equipment caused by detection errors caused by temperature factors is eliminated.

For example, the first temperature range may be a normal temperature environment, the temperature range may be set to-5 ℃ to 70 ℃, the second temperature range may be a high temperature environment, the temperature range may be greater than 75 ℃, the third temperature range may be a low temperature environment, the temperature range may be less than-5 ℃, the first duration may be set to 2s in the normal temperature environment, the second duration may be set to 4s in the high temperature environment, and the third duration may be set to 3s in the low temperature environment.

It should be noted that, when the temperature is at the critical value of the two temperature environments, the current environment needs to be determined as the abnormal temperature environment, and meanwhile, the statistical duration is adjusted accordingly, for example, when the current temperature is-5 ℃, it is determined that the current temperature is in the low temperature state, and at this time, the statistical duration needs to be set to 3 s; under the condition that the current temperature is 70 ℃, the current high-temperature state is judged, the counting time length needs to be set to 4s, the preset values at different temperatures are adjusted, and the effect of avoiding the temperature from influencing the judgment accuracy of the cover body state of the equipment is achieved.

Optionally, in the method for determining a device state provided in this embodiment of the present application, when the number of times of obtaining the target data in the statistical duration is greater than or equal to a first preset number of times, before determining that the current state of the cover body is the cover closing state, the method further includes: acquiring temperature data of target equipment, and determining a temperature range corresponding to the temperature data, wherein the frequencies of the target data acquired by the second wireless module at different temperatures are different; when the temperature range corresponding to the temperature data is a first temperature range, acquiring a first preset frequency and a second preset frequency determined in the first temperature range; when the temperature range corresponding to the temperature data is a second temperature range, acquiring a first preset number of times and a second preset number of times determined in 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 number of times determined in the second temperature range is smaller than the first preset number of times determined in the first temperature range, and the second preset number of times determined in the second temperature range is smaller than the second preset number of times determined in the first temperature range; and when the temperature range corresponding to the temperature data is a third temperature range, acquiring a first preset number of times and a second preset number of times determined in 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 number of times determined in the third temperature range is smaller than the first preset number of times determined in the first temperature range, and the second preset number of times determined in the third temperature range is smaller than the second preset number of times determined in the first temperature range.

Specifically, since the resonant capacitance of the resonant circuit changes under different temperatures, which may cause a change in the passing frequency, and the chip sweep times are different, the number of target data obtained within the statistical duration may change due to the temperature, which may cause an error in determining the state of the cover of the target device. Therefore, the first preset times and the second preset times under each statistical time length need to be correspondingly adjusted according to different temperatures, so that the condition that the cover opening and closing state of the target device is judged by mistake due to detection errors caused by temperature factors is eliminated.

For example, in the case of a normal temperature environment, the first preset number may be set to 7, and the second preset number may be 3; in a high-temperature environment, the first preset number of times can be set to 6, and the second preset number of times can be 2; in a low-temperature environment, the first preset number may be set to 5, and the second preset number may be 2.

It should be noted that when the temperature is at the critical value of the two temperature environments, the current environment needs to be determined as the abnormal temperature environment, and meanwhile, the statistical duration is correspondingly adjusted, for example, when the current temperature is-5 ℃, it is determined that the current temperature is in a low-temperature state, at this time, the first preset number needs to be set to 5, and the second preset number may be 2; under the condition that the current temperature is 70 ℃, the current state is judged to be the high-temperature state, at this time, the first preset times are required to be set to 6, and the second preset times can be 2.

Optionally, in the method for determining a device status provided in the embodiment of the present application, counting the number of times of obtaining target data within the counted duration includes: under the condition that the second wireless module receives a frame of target data, determining a time interval between the receiving time of the current frame of target data and the receiving time of the previous frame of target data; and under the condition that the time interval is smaller than the preset time interval, determining that the acquisition times of the target data in the statistical time interval are unchanged, and under the condition that the time interval is larger than or equal to the preset time interval, determining that the acquisition times of the target data in the statistical time interval are increased by one until the statistical time interval is reached, and outputting the acquisition times of the target data.

Specifically, when a certain frame of target data is received, the time interval between the receiving time of the current frame of target data and the receiving time of the previous frame of target data needs to be determined, whether the current frame of target data is the target data which is normally transmitted and received is judged through the time interval, and abnormal target data is not recorded, so that the influence of noise generated due to signal interference and the like on the counted target data is prevented, and the wrong judgment on the opening and closing state of the target device is avoided.

For example, the preset time interval may be 0.25s, when the current frame target data is acquired, the current record includes 3 times of target data, and when the time interval between the receiving time of the current frame target data and the receiving time of the previous frame target data is 0.3s, it is determined that the current frame target data is abnormal target data, and the target data is not recorded, and at this time, although 4 times of target data have been received, the current record still includes only frame number records corresponding to 3 times of target data; under the condition that the time interval between the receiving time of the current frame target data and the receiving time of the previous frame target data is 0.05s, if the current frame target data is an effective frame, recording the current frame target data, wherein the current record comprises frame number records corresponding to 4 times of target data, and acquiring the frame number of the current record under the condition that the statistical duration is reached, for example, under the condition that the statistical duration is 2s, if the effective frame number of the current record is 9 and is more than 7, determining that the current state of the target equipment is closed.

Fig. 2 is a flowchart of an alternative device status determination method according to an embodiment of the present application. As shown in fig. 2, the first time period is 2 seconds, the second time period is 4 seconds, the third time period is 3 seconds, the preset temperature range is-5 ℃ to 70 ℃, the first preset number of times is 7, the second preset number of times is 3, and in a high-temperature environment, the first preset number of times can be set to 6, and the second preset number of times can be 2; in a low-temperature environment, the first preset number may be set to 5, and the second preset number may be 2.

The device starts to work, and the initial cover body state of the current target device can be set to be the cover closing state. The swept-frequency oscillator starts to operate, and may transmit a radio frequency signal to the transponder at a preset frequency (e.g., data is transmitted every 200 ms), and receive target data when the resonant frequency of the radio frequency signal is the same as the resonant frequency of the transponder, where the target data may be target temperature data. And after the controller acquires the target temperature data, judging whether the target temperature data is in the range of-5-70 ℃.

When the target temperature data is in the range of-5 ℃ to 70 ℃, judging that the target equipment is in a normal temperature environment, counting the times of acquiring the target temperature data within 2 seconds, judging that the current state of the equipment is cover opening when the times are more than or equal to 7, judging that the current state of the equipment is cover opening when the times are less than or equal to 3, and judging that the current state of the equipment is the same as the state of the previous period and is cover closing when the times are more than 3 and less than 7.

When the target temperature data is higher than 70 ℃, the target equipment is judged to be in a high-temperature environment, the number of times of obtaining the target temperature data within 4 seconds is counted, the current state of the equipment is judged to be cover closing when the number of times is larger than or equal to 6, the current state of the equipment is judged to be cover opening when the number of times is smaller than or equal to 2, and the current state of the equipment is judged to be the same as the state of the previous period and is cover closing when the number of times is larger than 2 and smaller than 6.

When the target temperature data is less than-5 ℃, the target equipment is judged to be in a low-temperature environment, the number of times of obtaining the target temperature data within 3 seconds is counted, the current state of the equipment is judged to be cover closing under the condition that the number of times is more than or equal to 5, the current state of the equipment is judged to be cover opening under the condition that the number of times is less than or equal to 2, and the current state of the equipment is judged to be cover closing under the condition that the number of times is more than 2 and less than 5, so that the state judgment of opening and closing the cover of the target equipment under different temperatures is accurately judged.

According to an embodiment of the application, another method for judging the state of equipment is provided.

Fig. 3 is a flowchart of another method for determining a device status according to an embodiment of the present application. As shown in fig. 3, the method comprises the steps of:

step S302, obtain target data sent by a first wireless module through a second wireless module, where the second wireless module is disposed on a main body of a target device, and the first wireless module is disposed on a cover of the target device.

Specifically, the second wireless module may be a reader, specifically may be a swept-Frequency oscillator, and may be installed on a main body of the target device, the first wireless module may be a transponder whose resonant Frequency is a preset fixed value, the swept-Frequency oscillator and the transponder may communicate using an RFID (Radio Frequency Identification) technology, the swept-Frequency oscillator may send a Radio Frequency signal having a Frequency within a certain range to the transponder through the inductance coil according to a preset Frequency (for example, a Radio Frequency signal is sent every 200 ms), and when the resonant Frequency of the Radio Frequency signal sent by the swept-Frequency oscillator is the same as the preset resonant Frequency in the transponder, the swept-Frequency oscillator receives a target data signal sent in the transponder, obtains target data, and thereby completes wireless acquisition of the target data.

Step S304, setting a preset number of acquisition times of the target data.

Specifically, the preset number of times of acquiring the target data may be any value, for example, the preset number of times of acquiring the target data may be set to 4 times.

Step S306, determining the counting duration under the condition that the counted acquisition times reach the preset acquisition times.

Specifically, the statistical duration of the target data obtained for the preset obtaining times may be recorded, for example, the statistical time required for obtaining the target data for 4 times is recorded.

Step S308, under the condition that the statistical duration is less than or equal to the first statistical duration, determining that the current state of the cover body is the cover closing state.

Specifically, the time required for transmitting the target data is different between the cover opening state and the cover closing state, so that the statistical duration for obtaining the target data with the preset acquisition times can be recorded, and the opening and closing state of the cover body of the device can be judged according to the recorded statistical duration, wherein when the statistical duration is less than or equal to the first preset times, the current state of the cover body can be determined to be the cover closing state. For example, the first preset number of times may be 2s, and if the statistical duration is 1s, it may be determined that the current state of the cover body is the cover closing state.

And step S310, determining that the current state of the cover body is the uncovering state under the condition that the statistical time length is greater than or equal to the second statistical time length.

Specifically, when the counted time length is greater than or equal to the second preset number of times, it may be determined that the current state of the cover body is the uncovering state. For example, the second preset number of times may be 6s, and when the statistical duration is 7s, it may be determined that the current state of the lid is the uncapped state.

In step S312, when the statistical duration is smaller than the second statistical duration and greater than the first statistical duration, it is determined that the current state of the cover is the same as the state determined in the previous statistical duration.

Specifically, the current state of the cover body may be determined to be the same as the state determined in the previous statistical time period when the statistical time period is less than the second preset number of times and greater than the first preset number of times. For example, the first preset number of times may be 2s, the second preset number of times may be 6s, and when the statistical duration is 5s, it may be determined that the current state of the lid is the same as the state determined within the previous statistical duration, for example, if the state determined within the previous statistical duration is the lid opening, the current state of the lid determined within the current statistical period is the lid opening.

According to the method for judging the equipment state provided by the embodiment of the application, target data sent by a first wireless module is obtained through a second wireless module, wherein the second wireless module is arranged on a main body of target equipment, and the first wireless module is arranged on a cover body of the target equipment; setting preset acquisition times of target data; determining the statistical duration under the condition that the statistical acquisition times reach the preset acquisition times; determining the current state of the cover body as a cover closing state under the condition that the statistical time length is less than or equal to the first statistical time length; determining that the current state of the cover body is an uncovering state under the condition that the statistical time length is greater than or equal to the second statistical time length; and when the statistical duration is less than the second statistical duration and greater than the first statistical duration, determining that the current state of the cover body is the same as the state determined in the last statistical duration. The problem of need set up complicated lid detection mechanism that opens and shuts and detect cooking equipment lid state among the prior art to inaccurate to the testing result of cooking equipment lid state is solved. Through judging the number of times of receiving signals and judging the time two kinds of modes required by receiving the signals of the preset number of times in the preset time, the modification of the opening and closing judgment threshold value of the cover body of the cooking equipment is timely carried out under the condition of being influenced by the temperature, and the cover body state of the cooking equipment can be conveniently and accurately detected.

Optionally, in the method for determining a device status provided in the embodiment of the present application, the setting of the preset number of acquisition times of the target data includes: acquiring temperature data of target equipment, and determining a temperature range corresponding to the temperature data, wherein the frequencies of the target data acquired by the second wireless module at different temperatures are different; when the temperature range corresponding to the temperature data is a first temperature range, determining the first acquisition times as preset acquisition times; when the temperature range corresponding to the temperature data is a second temperature range, determining the second acquisition times as preset acquisition times, wherein the lower limit of the second temperature range is equal to the upper limit of the first temperature range, and the second acquisition times are smaller than the first acquisition times; and when the temperature range corresponding to the temperature data is a third temperature range, determining a third acquisition frequency as a preset acquisition frequency, wherein the upper limit of the third temperature range is equal to the lower limit of the first temperature range, the third acquisition frequency is less than the first acquisition frequency, and the second acquisition frequency is different from the third acquisition frequency.

For example, the first temperature range may be a normal temperature environment, the temperature range may be set to-5 ℃ to 70 ℃, the second temperature range may be a high temperature environment, the temperature range may be greater than 75 ℃, the third temperature range may be a low temperature environment, the temperature range may be less than-5 ℃, in the normal temperature environment, the first acquisition number may be set to 4, and 4 may be determined to be the preset acquisition number, in the high temperature environment, the second acquisition number may be set to 2, and 2 may be determined to be the preset acquisition number, in the low temperature environment, the third acquisition number may be set to 3, and 3 may be determined to be the preset acquisition number.

It should be noted that when the temperature is at the critical value of the two temperature environments, the current environment needs to be determined as the abnormal temperature environment, and meanwhile, the statistical duration is correspondingly adjusted, for example, when the current temperature is-5 ℃, it is determined that the current state is a low temperature state, at this time, the third obtaining frequency needs to be set to 3 times, and 3 needs to be determined as the preset obtaining frequency; under the condition that the current temperature is 70 ℃, the current state is judged to be a high-temperature state, at this moment, the second acquisition times are required to be set to 2 times, and 2 is determined as the preset acquisition times, and the effect of avoiding the temperature from influencing the state judgment accuracy of the cover body of the equipment is achieved by adjusting the preset values at different temperatures in the embodiment.

Optionally, in the method for determining a device state provided in this embodiment of the present application, when the statistical duration is less than or equal to the first statistical duration, before determining that the current state of the cover is the cover closing state, the method further includes: acquiring temperature data of target equipment, and determining a temperature range corresponding to the temperature data, wherein the frequencies of the target data acquired by the second wireless module at different temperatures are different; when the temperature range corresponding to the temperature data is a first temperature range, acquiring a first statistical time length and a second statistical time length determined in the first temperature range; when the temperature range corresponding to the temperature data is a second temperature range, acquiring a first statistical time length and a second statistical time length determined in 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 statistical time length determined in the second temperature range is longer than the first statistical time length determined in the first temperature range, and the second statistical time length determined in the second temperature range is longer than the second statistical time length determined in the first temperature range; and when the temperature range corresponding to the temperature data is a third temperature range, acquiring a first statistical duration and a second statistical duration determined in 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 statistical duration determined in the third temperature range is longer than the first statistical duration determined in the first temperature range, and the second statistical duration determined in the third temperature range is longer than the second statistical duration determined in the first temperature range.

Specifically, since the resonant capacitance of the resonant circuit changes under different temperatures, which may cause a change in the passing frequency, and the chip sweep times are different, the number of target data obtained within the statistical duration may change due to the temperature, which may cause an error in determining the state of the cover of the target device. Therefore, the first preset times and the second preset times in each temperature environment need to be adjusted correspondingly according to different temperatures, so that the condition that the cover opening and closing state of the target device is judged by mistake due to detection errors caused by temperature factors is eliminated.

For example, in the case of a normal temperature environment, the first statistical duration may be set to 2s, and the second statistical duration may be set to 6 s; in a high-temperature environment, the first statistical duration may be set to 3s, and the second statistical duration may be set to 7 s; in a low-temperature environment, the first statistical duration may be set to 3s, and the second statistical duration may be set to 8 s.

It should be noted that when the temperature is at the critical value of the two temperature environments, the current environment needs to be determined as the abnormal temperature environment, and the statistical duration is adjusted accordingly, for example, when the current temperature is-5 ℃, it is determined that the current state is a low temperature state, at this time, the first statistical duration needs to be set to 3s, and the second statistical duration needs to be set to 8 s; and under the condition that the current temperature is 70 ℃, judging that the current state is a high-temperature state, wherein the first statistical time length needs to be set to be 3s, and the second statistical time length needs to be set to be 7 s.

Optionally, when the preset number of times of acquisition is one, and when the number of times of acquisition is counted to reach the preset number of times of acquisition, determining the counted duration includes: and under the condition that the second wireless module receives a frame of target data, determining a time interval between the receiving time of the current frame of target data and the receiving time of the previous frame of target data, and determining the obtained time interval as the statistical duration.

Specifically, when the preset number of times is set to one time, when the target data is received, the time interval between the receiving time of the target data of the current frame and the receiving time of the target data of the previous frame may be determined as the statistical duration, and the opening and closing state of the cover body of the device may be determined according to the statistical duration.

Optionally, in the method for determining a device status provided in this embodiment of the present application, when the preset number of times of acquisition is greater than or equal to two times, and when it is counted that the number of times of acquisition reaches the preset number of times of acquisition, determining a counted duration includes: under the condition that the second wireless module receives a frame of target data, determining a time interval between the receiving time of the current frame of target data and the receiving time of the previous frame of target data; and under the condition that the time interval is smaller than the preset time interval, determining that the acquisition times of the target data are unchanged, under the condition that the time interval is larger than or equal to the preset time interval, determining that the acquisition times of the target data are increased by one until the acquisition times of the target data reach the preset acquisition times, and outputting the statistical duration corresponding to the preset acquisition times.

Specifically, when a certain frame of target data is received, the time interval between the receiving time of the current frame of target data and the receiving time of the previous frame of target data can be determined, whether the current frame of target data is the target data which is normally transmitted and received is judged through the time interval, and abnormal target data is not recorded, so that the influence of noise generated due to signal interference and the like on the counted target data is prevented, and the wrong judgment on the cover opening and closing state of the target equipment is avoided.

For example, the preset time interval may be 0.25s, when current frame target data is obtained, the current record includes target data for 3 times, when the time interval between the receiving time of the current frame target data and the receiving time of the previous frame target data is 0.3s, it is determined that the current frame target data is abnormal target data at this time, and then the target data is not recorded, and at this time, although the target data has been received for 4 times, only frame number records corresponding to the target data for 3 times are still included in the current record; under the condition that the time interval between the receiving time of the current frame target data and the receiving time of the previous frame target data is 0.05s, if the current frame target data is an effective frame, recording the current frame target data, wherein the current record comprises frame number records corresponding to 4 times of target data, and acquiring the frame number of the current record under the condition of reaching the statistical duration.

Fig. 4 is a flowchart of another alternative device status determination method according to an embodiment of the present application. As shown in fig. 4, where the first obtaining number is 4, the second obtaining number is 2, and the third obtaining number is 3, in the case of a normal temperature environment, the first statistical duration may be set to be 2s, and the second statistical duration may be set to be 6 s; in a high-temperature environment, the first statistical duration may be set to 3s, and the second statistical duration may be set to 7 s; in a low-temperature environment, the first statistical time period may be set to 3s, and the second statistical time period may be set to 8 s.

The target device starts to work, and the initial cover body state of the current target device can be set to be the cover closing state. The swept-frequency oscillator starts to operate, and may transmit a radio frequency signal to the transponder at a preset frequency (e.g., data is transmitted every 200 ms), and receive target data when the resonant frequency of the radio frequency signal is the same as the resonant frequency of the transponder, where the target data may be target temperature data. And after acquiring the target temperature data, the controller judges whether the target temperature data is in the range of-5-70 ℃.

When the target temperature data is in the range of-5 ℃ to 70 ℃, judging that the target equipment is in a normal temperature environment, starting timing, stopping timing when the acquisition of the target data is completed for 4 times is recorded, confirming the time required for completing the acquisition of the target data for 4 times, judging that the current state of the equipment is the cover opening under the condition that the acquisition time is more than or equal to 6s, judging that the current state of the equipment is the cover closing under the condition that the acquisition time is less than or equal to 2s, and judging that the current state of the equipment is the same as the state of the previous period and is the cover closing under the condition that the acquisition time is more than 2s and less than 6 s.
