The WI-FI transceiver module is existing, connected in the form of a connector, firmly installed, and easy to maintain; through the WI-FI transceiver module, a stronger communication frequency band (2.4GHz) can be achieved, the transmission rate is faster, and the installation is convenient, without on-site wiring. Generally, as long as one or more access devices are installed, a network covering the entire area can be established; the wireless LAN can access the network at any location within the wireless signal coverage area, and users connected to the wireless LAN can move and stay connected through the time domain network, with strong flexibility and mobility.

[0027] Further, if Figure 1~2 As shown, in this embodiment, the power module includes: a connector JP1, which is connected to the transmitter circuit board and outputs the voltage of the transmitter circuit board; a step-down circuit, which is connected to the connector JP1 and the WI-FI transceiver module and is used to power the WI-FI transceiver module. The connector JP1 is a pin header, wherein pin 1 is GND, pin 2 is +5V, pin 3 is RXD, pin 4 is TXD, pin 5 is GND, and the other pins are suspended (NC). Pin 2 is connected to the DC power supply 5V of the transmitter board to power the WI-FI module. Pins 3 and 4 are used to transmit data with the transmitter board, and the working mode is half-duplex. Pins 1 and 5 are ground terminals. The pin header provides a standardized connection method, which is convenient for plugging and unplugging and replacing between modules, simplifies the installation process, and reduces the possibility of errors. The step-down circuit can reduce the voltage of the transmitter circuit board to the working voltage required by the WiFi transceiver module, ensuring the stable operation of the WiFi module and protecting the module from damage by high voltage.

[0028] Further, if Figure 2As shown, in this embodiment, the step-down circuit includes: a first capacitor 1C1, a second capacitor 1C2, a third capacitor 1C3, a fourth capacitor 1C4 and a power management chip 1U1; the first capacitor 1C1 and the second capacitor 1C2 are connected in parallel; one end of the first capacitor 1C1, one end of the second capacitor 1C2 and the input end of the power management chip 1U1 are connected to the output end of the connector JP1; the third capacitor 1C3 and the fourth capacitor 1C4 are connected in parallel; one end of the third capacitor 1C3, one end of the fourth capacitor 1C4 and the output end of the power management chip 1U1 are connected; the other end of the first capacitor 1C1, the other end of the second capacitor 1C2, the other end of the third capacitor 1C3, the other end of the fourth capacitor 1C4 and the ground end of the power management chip 1U1 are connected and grounded, the power management chip 1U1 is a linear regulator, the linear regulator uses an LM1117-LMPX-3.3V chip, and the step-down circuit converts the DC 5V power provided by the transmitter circuit board into DC 3.3V and then provides it to the WI-FI transceiver module for power supply.

[0029] like Figure 4 As shown, the MCU and other devices on the far left send serial port data to the WI-FI module. After the RXD port of the WI-FI module receives the serial port data, it automatically sends the data to the air in the form of radio waves. After the WI-FI device on the far right receives the data transmitted in the air, it further processes the data and converts the required data. The WI-FI device on the far right sends the data to the air in the form of radio waves. The WI-FI module receives the radio wave data in the air and converts it into serial port data, which is sent to the leftmost device by the TXD end of the WI-FI module. The RXD port on the far left receives the data sent by the WI-FI module.
