the first communication demodulation circuit 104 is configured to demodulate the received carrier to obtain original second data to be sent, and transmit the second data to be sent to the first main control chip 101.
With respect to the above preferred solution, it should be noted that the transmitting coil 204 and the receiving coil 106 may be adjacently disposed, and the distance between the two is less than 50 mm, so that the receiving coil 106 is within the range of the electromagnetic field generated by the transmitting coil 204, resulting in an induced voltage on the receiving coil 106. When the receiving coil 106 generates inductive power, the alternating voltage passes through the rectifying circuit 102 and the voltage stabilizing circuit 103, and then a stable direct current power supply for other loads is generated.
In addition, when the time length required for the power receiver 10 to transmit the first data to be transmitted is T2 and the time length required for the power transmitter 20 to transmit the second data to be transmitted is T3, considering the time length of data transmission, the time length T of the transmission period satisfies the following condition:

combining the above technical solutions shown in fig. 1 and fig. 2, the communication apparatus 10 shown in fig. 1 and fig. 2 can be applied to a device, which includes: an apparatus main body, a detachable portion, and any of the communication devices 1 described in fig. 1 and 2; wherein the communication device 1 comprises: a wireless charging power transmitter 20 and a wireless charging power receiver 10, said power receiver 10 being arrangeable in said detachable part.

Taking the electric pressure cooker as an example, referring to fig. 3, which is a front view of an atypical example of the electric pressure cooker 30, the electric pressure cooker 30 may include an upper cover 301 and a cooker body 302; the upper cover 301 is detachably attached to the pot body 302, and therefore, the pot body 302 is an apparatus main body, and the upper cover 301 is a detachable portion. Since the upper cover 301 of the existing electric pressure cooker is provided with detection devices for detecting the temperature value and the pressure value of the inner cavity of the inner container of the electric pressure cooker, when the upper cover 301 can be detachably installed, the electric power required by the detection devices can be provided through wireless charging, and the control unit in the cooker body 302 needs to receive the detection data sent by the detection devices from the upper cover 301 and send a control instruction to the control unit in the upper cover 302 according to the detection data so as to control the opening and closing of the exhaust valve in the upper cover 301. Therefore, according to the communication means shown in fig. 1 or fig. 2, it is possible to accomplish data interaction between the upper cover 301 and the pot body 302 while realizing the supply of electric power to the detection means of the detachable upper cover 301.
Example two
Based on the same technical concept as the foregoing embodiment, referring to fig. 4, a communication method provided in an embodiment of the present invention is shown, where the method may be applied to a home appliance, and the home appliance may include a wirelessly charged power transmitting end and a wirelessly charged power receiving end, and the method includes:
s401: the power receiving end sends the first data to be sent to the power transmitting end through a receiving coil carrier according to a set transmission period;
s402: the power transmitting terminal receives first data to be transmitted and checks the first data to be transmitted;
s403: after the first data to be transmitted is successfully checked, the power transmitting terminal transmits second data to be transmitted to the power receiving terminal through the transmitting coil carrier after a set interval duration;
wherein the time length T of the transmission cycle is greater than the preset interval duration T1.
It should be noted that, the interaction between information and data between two ends of wireless charging needs to be realized through a coil carrier, and therefore, the communication between the two ends belongs to a half-duplex mode, and for the technical scheme shown in fig. 4, the interaction between information and data is performed by setting a fixed time interval, so as to avoid communication disorder between a power receiving end and a power transmitting end; and the time length of the transmission period of the power receiving end is set to be longer than the interval time of the power transmitting end for transmitting data, so that at most only one end between the power receiving end and the power transmitting end transmits data at a certain time point, and thus, the communication conflict generated when the power receiving end and the power transmitting end communicate in a wireless charging state is avoided, and the power receiving end and the power transmitting end can communicate in order.
With reference to the communication apparatus described in the foregoing embodiment, it can be known that the power receiving end and the power transmitting end in the technical solution shown in fig. 4 correspond to the power receiver and the power transmitter in the communication apparatus, respectively.
As an implementation manner, it should be noted that, when the first data to be transmitted is used to characterize the operating state of the device, the second data to be transmitted includes a control instruction corresponding to the operating state. Then, when the first data to be transmitted is used to represent the operating state of the device, the power transmitting terminal transmits second data to be transmitted to the power receiving terminal through a transmitting coil carrier after a set interval duration, which includes the following three steps:
the power transmitting terminal acquires the working state of the equipment according to the first data to be transmitted;
the power transmitting terminal acquires a corresponding control instruction according to the working state of the equipment;
and the power transmitting terminal transmits the control instruction to the power receiving terminal through a transmitting coil carrier after a set interval duration.
Taking the electric pressure cooker as an atypical example, the power transmitting end for wireless charging can be arranged in the cooker body of the electric pressure cooker, and the power receiving end for wireless charging can be arranged in the upper cover of the electric pressure cooker. For the electric pressure cooker, the upper cover is detachably arranged on the cooker body, so that when the upper cover is provided with a detection device for detecting the temperature value and the pressure value of the inner cavity of the inner container, the detection device can be powered in a wireless charging mode. It should be noted that the detection data obtained by the detection device needs to be transmitted from the upper cover to the control unit in the pot body, and the control unit in the pot body determines whether to open or close the exhaust valve in the upper cover according to the detection data, so the pot body also needs to send a control command regarding the exhaust valve to the upper cover according to the detection data, so that the control unit in the upper cover controls the opening and closing of the exhaust valve according to the control command. Therefore, the parameters, such as the inner cavity temperature value and the inner cavity pressure value, which are used for describing the working state of the electric pressure cooker, of the detection data obtained by the detection device in the upper cover are the first data to be sent; and the control unit in the cooker body obtains a control instruction of the exhaust valve according to the detection data, the control instruction is second data to be sent, and the control unit in the upper cover can control the opening and closing of the exhaust valve according to the instruction of the control instruction after receiving the control instruction.
Specifically, still taking the electric pressure cooker as an example, the upper cover of the electric pressure cooker is provided with a sensor for detecting temperature and pressure of the inner cavity of the inner container, and is also provided with a power receiver for wireless charging, and the power receiver is marked as a host in the specific example; a control unit for analyzing data is arranged in a pot body of the electric pressure cooker, and because the pot body of the electric pressure cooker can be directly supplied with power by commercial power, a power transmitter for wireless charging is arranged, which is identified as a slave in the specific example, referring to a waveform timing diagram shown in fig. 5, the master can send detection data of a sensor to the slave according to a fixed transmission period T; after receiving the detection data, the slave machine verifies the detection data, and after the verification is successful, sends response data aiming at the detection data to the host machine after a preset interval duration t 1; it can be understood that, when the detected data is the temperature value and the pressure value of the inner cavity, the response data may be a control command corresponding to the temperature value and the pressure value of the inner cavity, for controlling the opening and closing of the exhaust valve in the upper cover. After the host receives the response data, the upper cover controls the exhaust valve according to the response data.
As an implementation manner, if the duration of data transmission is considered, when the duration required by the power receiving end to transmit the first data to be transmitted is T2 and the duration required by the power transmitting end to transmit the second data to be transmitted is T3, the time length T of the transmission period satisfies the following condition:
T>t1+t2+t3。
the embodiment provides a communication method, which performs information and data interaction by setting a fixed time interval, so as to avoid communication disorder between a power receiving end and a power transmitting end, and also avoid communication collision between the power receiving end and the power transmitting end during wireless charging, so that the power receiving end and the power transmitting end can perform ordered communication.
