According to an embodiment of the present application, there is provided a device communication method.

Fig. 1 is a flowchart of a device communication method provided according to an embodiment of the present application. As shown in fig. 1, the method comprises the steps of:

step S102, sending a start signal to the first wireless module through the second wireless module, and determining whether the second wireless module receives target data sent by the first wireless module, where the second wireless module is disposed on the main body of the target device, the first wireless module is disposed on the cover of the target device, and the first wireless module sends the target data to the second wireless module after being started.

Specifically, the second wireless module can be for reading the ware, can install in target device's main part, and power supply for reading the ware power supply through target device, and first wireless module can be the transponder, installs on the lid, and the transponder can not connect the power, reads the ware and constantly sends start signal to the transponder to supply power to the transponder through inductance coils. The reader and the responder can communicate by adopting an RFID (Radio Frequency Identification) technology, specifically, the reader and the responder agree to communicate at a preset resonant Frequency, the reader responder transmits a target data signal according to the preset resonant Frequency, and the reader receives the target data signal transmitted by the responder according to the preset resonant Frequency.

For example, the target device may be cooking equipment, the target data may be temperature data, the temperature measurement module and the transponder may be installed on a lid of the cooking equipment, the reader and the control module may be installed on a main body of the cooking equipment, the temperature measurement module sends the temperature data to the transponder after detecting the temperature of the lid of the equipment, after the reader sends a start signal to the transponder, the transponder starts to operate, a wireless connection may be established between the reader and the transponder, at this time, the reader may acquire the temperature data sent by the transponder, and send the temperature data to the control module, the control module may perform the judgment of the status of the lid of the equipment according to the frequency acquired by the temperature data and the temperature data.

Step S104, when the second wireless module does not receive the target data sent by the first wireless module, adjusting the resonant frequency of the second wireless module among a plurality of preset frequencies until the second wireless module receives the target data, or until the second wireless module finishes traversing the plurality of preset frequencies.

Specifically, the second wireless module may be a reader, the first wireless module may be a transponder, and when the sweep frequency oscillator does not receive the target data sent by the transponder, it indicates that the resonant frequency of the resonant circuit in the transponder is changed due to the influence of temperature, so that the resonant frequency of the reader is different from the resonant frequency of the transponder, and therefore the reader cannot receive the target data sent by the transponder. Therefore, the frequency sweeping function can be integrated in the reader to form the frequency sweeping oscillator, the resonant frequency of the frequency sweeping oscillator can be sequentially adjusted among a plurality of preset frequencies, whether target data sent by the transponder can be received under the resonant frequency after each adjustment is judged, the adjustment operation of the resonant frequency is stopped under the condition that the target data is received, the resonant frequency of the reader is continuously adjusted under the condition that the target data cannot be received until all the preset frequencies are traversed, namely, the resonant frequency of the transponder is searched in a frequency sweeping mode, so that the resonant frequencies of the reader and the transponder are consistent, and the wireless transmission of the data is completed.

For example, the target device may be a cooking device, the transponder is mounted on a cover of the cooking device, the reader is mounted on a main body of the cooking device, when the cooking device is in operation, a temperature of the cover is continuously increased, when the temperature of the cover is too high, a resonant frequency of the transponder changes due to a change in a capacitance value in the resonant circuit, and at this time, target data transmitted by the transponder cannot be acquired by the reader, and a resonant frequency of the reader may be sequentially adjusted among a plurality of preset frequencies, for example, the preset resonant frequency of the transponder and the reader may be 13.56M, and the plurality of preset frequencies may include 13.55M and 13.45M, where the reader cannot receive the target data transmitted by the transponder when the resonant frequency is 13.56M, and adjust the resonant frequency of the reader to 13.55M, and determine whether the target data can be received, where the target data can be received, if the target data can be received, the adjustment of the resonant frequency is stopped, and if the target data cannot be received, the adjustment of the resonant frequency of the reader is stopped, and if all the target data cannot be received, the target data is traversed, the adjustment is also completed.

It should be noted that, the number and specific numerical values of the multiple preset frequencies are not limited in this embodiment, in addition, the resonant frequency may be periodically adjusted among the multiple preset frequencies, and the number of times of periodically adjusting the resonant frequency may be set, for example, the number of times is set to 3 times, and the resonant frequency may be adjusted among the multiple preset frequencies in 3 rounds until the reader receives the target data, and the adjustment of the resonant frequency is stopped, or the adjustment of the resonant frequency is stopped until 3 rounds of traversal is completed, so that the adjustment error is reduced.

According to the device communication method provided by the embodiment of the application, a starting signal is sent to a first wireless module through a second wireless module, and whether the second wireless module receives target data sent by the first wireless module is judged, wherein the second wireless module is arranged on a main body of target equipment, the first wireless module is arranged on a cover body of the target equipment, and the first wireless module sends the target data to the second wireless module after being started; under the condition that the second wireless module does not receive the target data sent by the first wireless module, the resonant frequency of the second wireless module is adjusted among the preset frequencies until the second wireless module receives the target data, or the preset frequencies are reached after traversal is completed, and the problem that different wireless modules cannot transmit data through a radio frequency identification technology due to temperature factors in the related technology is solved. Through adjusting the resonant frequency adaptation of the second wireless module and the resonant frequency adaptation of the first wireless module, the second wireless module can also normally communicate with the first wireless module under the condition that the resonant frequency of the first wireless module changes, and then the effect that the second wireless module and the first wireless module can normally transmit data under the condition that the temperature is abnormal is achieved.

In order to prevent the misjudgment of the receiving condition of the target signal caused by the reason that the signal is interfered, optionally, in the device communication method provided in this embodiment of the application, the sending the start signal to the first wireless module by the second wireless module, and determining whether the second wireless module receives the target data sent by the first wireless module includes: sending a starting signal to the first wireless module through the second wireless module according to a preset time interval, and judging whether the second wireless module receives target data or not when the sending times of the starting signal reach the target times; when the sending times of the starting signal reach the target times and the second wireless module does not receive the target data, determining that the second wireless module does not receive the target data sent by the first wireless module; or sending a starting signal to the first wireless module through the second wireless module according to a preset time interval, and judging whether the second wireless module receives the target data within a preset time length after the starting signal is sent for the first time; and under the condition that the second wireless module does not receive the target data within the preset time length, determining that the second wireless module does not receive the target data sent by the first wireless module.

Specifically, the second wireless module may be a reader, the first wireless module may be a transponder, and the reader supplies power to the transponder by continuously sending an activation signal to the transponder, for example, the activation signal may be sent to the transponder every 200ms, and the sending times are counted at the same time.

In an optional implementation manner, whether the reader receives the target data sent by the transponder may be determined by the number of times the reader sends the start signal, and if the target data is not received yet when the number of times the reader sends the start signal reaches the target sending number, it may be determined that the target data cannot be received due to the fact that the resonant frequencies of the reader and the transponder are different, and at this time, it may be determined that the reader does not receive the target data sent by the transponder, and the resonant frequency of the reader may be adjusted among a plurality of preset frequencies.

For example, the target number of times may be 4, when the reader sends the start signal to the transponder 1 to 3 times, the reader may not receive the target data due to poor signal or incomplete start, and at this time, it cannot be determined that the temperature affects the resonant frequency of the transponder, and the reader cannot receive the target data sent by the transponder, and if the target data is not received by continuously sending the start signal for 4 times, it may be determined that the target data cannot be received due to the difference between the resonant frequencies of the reader and the transponder.

In another optional implementation manner, whether the target data sent by the transponder is received by the reader or not may be determined by determining whether the target data is received within a preset time period after the reader sends the start signal for the first time, the sending time is recorded when the reader sends the start signal to the transponder, and the target data is not received within the preset sending time period after the start signal is sent for the first time, which may be determined to be caused by different resonant frequencies of the reader and the transponder, and at this time, it may be determined that the target data sent by the transponder is not received by the reader, and the resonant frequency of the reader may be adjusted among a plurality of preset frequencies.

For example, the preset time duration may be 2s, when the reader sends the first start signal to the transponder, the reader may not receive the target data due to poor signal or incomplete start, and at this time, it cannot be determined that the temperature affects the resonant frequency of the transponder, so that the reader cannot receive the target data sent by the transponder, and the target data is not received until the sending time of the start signal reaches 2s in an accumulated manner, which may be determined that the target data is caused by different resonant frequencies of the reader and the transponder.

In order to improve the adaptation speed of the resonant frequency of the second wireless module and the resonant frequency of the first wireless module, optionally, in the device communication method provided in this embodiment of the application, adjusting the resonant frequency of the second wireless module among a plurality of preset frequencies until the second wireless module receives the target data includes: and adjusting the resonant frequency of the second wireless module among a plurality of preset frequencies according to a preset sequence until the second wireless module receives the target data.

Specifically, the second wireless module can be for reading the ware, first wireless module can be the transponder, after having confirmed that the ware can't receive the target data that the transponder sent, can adjust resonant frequency between a plurality of frequencies of predetermineeing according to predetermined order, wherein, predetermined frequency can be for the historical resonant frequency of transponder under abnormal temperature environment, predetermined order can be from high to low order for the number of times of appearance of historical resonant frequency, make the resonant frequency adaptation with the transponder that the resonant frequency of reading the ware can be more quick, thereby improve connection efficiency and the rate of accuracy between ware and the transponder.

For example, during the test phase, the resonant frequency of the transponder at normal temperature may be 13.56M, and the resonant frequency of the transponder measured at abnormal temperature is: 12.5M, the probability of occurrence is 30%, 12.3M, the probability of occurrence is 25%, 11.8M, and the probability of occurrence is 31%, the preset frequency may be 12.5M, 12.3M, 11.8M, and the preset order may be 11.8M, 12.5M, 12.3M.

It should be noted that, after the resonant frequency is adjusted for one period among the multiple preset frequencies according to the preset sequence, because there is a situation that the target data cannot be acquired due to an abnormal factor in one period, the embodiment may also adjust the resonant frequency for multiple periods, thereby improving the accuracy of the wireless connection between the reader and the transponder.

In order to improve the speed of adapting the resonant frequency of the second wireless module to the resonant frequency of the first wireless module, optionally, in the device communication method provided in this embodiment of the present application, adjusting the resonant frequency of the second wireless module between a plurality of preset frequencies until the second wireless module receives the target data includes: the resonant frequency is adjusted by subtracting the preset frequency value on the basis of the resonant frequency, and if the target data is received by the second wireless module before the first number of preset frequency values is subtracted on the basis of the resonant frequency, the adjustment of the resonant frequency is stopped, wherein the first number is determined by the number of the plurality of preset frequencies.

Specifically, since the resonant frequency of the resonant circuit is usually reduced due to the abnormal temperature, after it is determined that the reader cannot receive the target data transmitted by the transponder, the resonant frequency of the reader may be adjusted by subtracting a preset frequency value from the resonant frequency until the target data transmitted by the transponder is successfully acquired or the frequency value is reduced for the first time.

For example, the preset frequency value may be 13.56m × 2% =0.27M, when the reader continuously transmits a start signal 4 times and does not receive the target data for 4 times, the preset resonant frequency of the reader is decreased by 2%, that is, 0.27M, and is changed to 13.29M, and it is determined whether the target data is received, and the resonant frequency of the reader is continuously decreased by 2%, that is, 0.27M, until the target data is received, or the adjustment number reaches a first number, where the first number may be 5 times, that is, the target data is not received after the resonant frequency is decreased by 5 times, and it is determined that the reader cannot successfully receive the target data.

In order to improve the speed of adapting the resonant frequency of the second wireless module to the resonant frequency of the first wireless module, optionally, in the device communication method provided in this embodiment of the present application, adjusting the resonant frequency of the second wireless module between a plurality of preset frequencies until the second wireless module receives the target data includes: the resonant frequency is adjusted by increasing the preset frequency value on the basis of the resonant frequency, and if the second wireless module receives the target data before the second number of preset frequency values is increased on the basis of the resonant frequency, the adjustment of the resonant frequency is stopped, wherein the second number of times is determined by the number of the preset frequencies.

Specifically, since the resonant frequency of the resonant circuit is increased due to the abnormal temperature, after it is determined that the reader cannot receive the target data sent by the transponder, the resonant frequency of the reader can be adjusted in a manner of increasing a preset frequency value on the basis of the resonant frequency until the target data sent by the transponder is successfully acquired or the frequency value is increased for the first time.

For example, the preset frequency value may be 13.56m × 2% =0.27M, when the target data is not received when the reader continuously transmits 4 times of start signals, the resonant frequency of the reader is increased by 2%, that is, 0.27M, and changed to 13.29M, and whether the target data is received is determined, and when the target data is not received, the resonant frequency of the reader is continuously increased by 2%, that is, 0.27M, until the target data is received, or the adjustment number reaches a second number, where the second number may be 5, that is, when the target data is not received after the resonant frequency is increased by 5 times, it is determined that the target data cannot be successfully received.

In order to improve the speed of adapting the resonant frequency of the second wireless module to the resonant frequency of the first wireless module, optionally, in the device communication method provided in this embodiment of the present application, adjusting the resonant frequency of the second wireless module between a plurality of preset frequencies until the second wireless module receives the target data includes: adjusting the resonant frequency by subtracting the preset frequency value on the basis of the resonant frequency, and stopping adjusting the resonant frequency if the second wireless module receives the target data before the third preset frequency value is subtracted on the basis of the resonant frequency; if the second wireless module does not receive the target data after the third preset frequency value is decreased on the basis of the resonant frequency, adjusting the resonant frequency in a manner of increasing the preset frequency value on the basis of the resonant frequency; and stopping adjusting the resonant frequency if the second wireless module receives the target data before the fourth preset frequency value is increased progressively on the basis of the resonant frequency, wherein the sum of the third time and the fourth time is determined by the number of the preset frequencies.

Specifically, since the temperature abnormality usually causes a decrease in the resonant frequency of the resonant circuit, and there is also a case that the resonant frequency of the resonant circuit increases, after it is determined that the reader cannot receive the target data transmitted by the transponder, the frequency may be adjusted by subtracting a preset frequency value on the basis of the resonant frequency, and when the adjustment frequency reaches a third time and the target data cannot be successfully acquired, the resonant frequency of the reader may be adjusted by increasing the preset frequency value on the basis of the initial resonant frequency until the frequency value is increased to a fourth time. If the target data is not received all the time in the period, determining that the target data cannot be successfully received; and if the target data is successfully received, stopping the adjustment of the resonant frequency.

For example, the preset frequency value may be 13.56m × 2% =0.27M, when the reader continuously transmits 4 times of start signals and does not receive the target data for 4 times, the resonant frequency of the reader is reduced by 2%, that is, 0.27M, and is changed to 13.29M, and whether the target data is received is determined, and when the target data is not received, the resonant frequency of the reader is continuously reduced by 2%, that is, 0.27M, until the target data is received, or the adjustment number reaches a third number, where the third number may be 3 times, that is, the target data is not received after the resonant frequency is reduced by 3 times, and the resonant frequency is increased on the basis of the initial resonant frequency. Specifically, the resonant frequency of the reader may be increased by 2% on the basis of the preset resonant frequency, that is, 0.27M, until the target data is received, or the adjustment frequency reaches a fourth frequency, where the fourth frequency may be 4 times, that is, the target data is not received after the resonant frequency is increased by 4 times, and it is determined that the target data cannot be successfully received.

Optionally, in the device communication method provided in this embodiment of the present application, in a case that the second wireless module does not receive the target data sent by the first wireless module, the method further includes, after the second wireless module receives the target data, adjusting a resonant frequency of the second wireless module: and sending the received target data to the controller through the second wireless module.

Specifically, after receiving the target data, the reader sends the received target data to the controller, the controller determines a value of the target data and a receiving frequency of the target data, and can determine a state of the cover of the target device according to the value of the target data and the receiving frequency of the target data.

Optionally, in the device communication method provided in this embodiment of the present application, in a process of adjusting the resonant frequency of the second wireless module among a plurality of preset frequencies, if the second wireless module still does not receive the target data after traversing the plurality of preset frequencies, the second wireless module sends a prompt message to the controller, where the prompt message is used to prompt that the target device is in an uncapped state.

In the case of abnormal temperature, the capacitance value becomes large because the temperature affects the capacitance parameter of the resonant circuit, and the capacitance value becomes small rapidly after the temperature exceeds the high temperature of the normal working range of the wireless upper module, and similarly, the capacitance value becomes small after the temperature is lower than the low temperature of the normal working range. According to the resonant frequency formula, the resonant frequency is changed due to the capacitance value change, and the resonant frequency of the wireless upper module is not close to the normal initial resonant frequency (13.56M), so that the wireless lower module cannot receive the temperature data of the wireless upper module.

If the wireless lower module cannot receive the target data at 10 points in the interval with the frequency of 13.56M +/-10%, at the moment, the wireless lower module sends prompt information to the controller to prompt that the target equipment is in an uncapped state.
