Description

Wireless charging system, communication method thereof and storage medium
Technical Field
The invention relates to the field of wireless charging systems, in particular to a wireless charging system, a communication method thereof and a storage medium.
Background
The wireless charging system comprises a transmitting end and a receiving end, wherein the transmitting end comprises a transmitting end central control module, a transmitting end communication module and a power transmitting module which are respectively controlled by the transmitting end central control module, and the receiving end comprises a receiving end central control module, a power receiving module and a receiving end communication module which are respectively controlled by the receiving end central control module.
In the existing wireless charging system, a transmitting end and a receiving end are mainly communicated in two ways.
1. Out-of-band communication:
the transmitting terminal communication module intermittently transmits Ping signals, and after the receiving terminal responds, the transmitting terminal enters a power transmission stage according to the request of the receiving terminal;
when the receiving end receives the power transmitted by the transmitting end, the receiving central control system is powered on, the receiving end communication module sends the receiving end state and the receiving end request back to the transmitting end, and the transmitting end adjusts the transmitting power according to the request.
2. And (3) carrier communication: the power transmitting module and the power receiving module carry out FSK signal communication, namely, in a certain period, the transmitting end changes the transmitting frequency to form a data signal, and the receiving module receives the frequency change to analyze data. FSK signals can only transmit signals on the corresponding transmitting and receiving modules.
When the first communication mode is applied to a working scene with only a single transmitting end and a single receiving end, the first communication mode has the advantages of strong communication signals and stable communication. However, in practical situations, there may be multiple transmitting terminals and multiple receiving terminals on the same occasion, and the wireless communication modules are bidirectional signal transmission modules, and the transmission distance thereof is generally 10m, so that if there are multiple wireless communication modules in the same space (10m), they can communicate with each other. Therefore, assuming that two working systems, namely, ATX (a transmitting module), ARX (a receiving module), BTX (B transmitting module) and BRX (B receiving module), work simultaneously in the same space, signals transmitted by ARX, ATX and BTX can both receive signals simultaneously, at this time, ATX can make a correct response, and BTX can make an incorrect response to cause system breakdown, so that the disadvantage is that other wireless charging systems are easily interfered in the same environment.
The main drawbacks of the second communication method are: the communication signal is susceptible to power supply ripple.
Disclosure of Invention
One objective of the present invention is to provide a wireless charging system that is not easily interfered with communication.
In order to achieve the purpose, the invention adopts the following technical scheme:
the wireless charging system comprises a transmitting end and a receiving end, wherein the transmitting end comprises a transmitting end central control module, a transmitting end communication module and a power transmitting module, and the receiving end comprises a receiving end central control module, a power receiving module and a receiving end communication module:
the transmitting end central control module loads the Ping signal sent by the transmitting end communication module into an FSK signal, the FSK signal uses a unique address, and the communication address of the transmitting end communication module is set as the address of the FSK signal;
the receiving end central control module is electrified after the power receiving module receives power, analyzes the address of the FSK signal, sets the communication address of the receiving end communication module as the address of the analyzed FSK signal, and controls the receiving end communication module to send out a receiving end state and a request signal;
and after the transmitting terminal communication module receives the signal corresponding to the local address, the wireless charging system enters a power transmission stage.
Another objective of the present invention is to provide a wireless charging system communication method that can enable multiple wireless charging systems to work simultaneously without interfering with each other.
In order to achieve the purpose, the invention adopts the following technical scheme:
the communication method of the wireless charging system carries out communication according to the following modes:

s2, loading the Ping signal into an FSK signal by a central control module at a transmitting end while sending the Ping signal, wherein the FSK signal uses a unique address; the transmitting end central control module sets the communication address of the transmitting end communication module as the address of the FSK signal;
s3, after the power receiving module receives the power, the central control module of the receiving end is electrified and analyzes the address of the FSK signal; setting the communication address of the communication module of the receiving end as the address of the FSK signal;
s4, the receiving end communication module sends out the receiving end state and the request signal;
and S5, after the transmitting terminal communication module receives the signal corresponding to the local address, the wireless charging system enters a power transmission stage.
Still another objective of the present invention is to provide a wireless charging system communication method that can enable multiple wireless charging systems to work simultaneously without interfering with each other.
In order to achieve the purpose, the invention adopts the following technical scheme:
the computer readable medium stores a program, which is executable by a processor to implement the steps of the wireless charging system communication method as described above.
After adopting the technical scheme, compared with the background technology, the invention has the following advantages:
the invention improves the communication method, loads the Ping signal into the FSK signal, and sets a unique address for each transmitting end communication module and the corresponding receiving end communication module, thereby avoiding the communication error caused by the cross and error transmission of the signal; meanwhile, the FSK signal is only sent at the Ping stage, and the power supply ripple in the subsequent normal work cannot be influenced.
