The main control module is a central control unit of the gateway and comprises a CPU, a memory, an interface and a gateway main control program, after the gateway is powered on, the CPU starts to work and runs the main control program to realize various functions of the gateway.
Further, when the application site can not provide Ethernet access, an optional WiFi or GPRS/3G/4G module is added to the interface part of the basic network so as to communicate with the background server.
Furthermore, when any one of the wireless communication modules receives a data packet from a third-party wireless terminal, the data packet is transmitted to the main control module through the sensing network interface, and the main control module forwards the data packet to the background server through the Ethernet module for processing; when the background server processes the data packet and then needs to send the data packet to the wireless terminal, the background server sends the data packet with the type mark to the main control module through the Ethernet module, the main control module sends the data packet to the corresponding wireless communication module through the sensing network interface according to the type mark of the data packet, and the wireless communication module sends the data packet to the corresponding third-party wireless terminal in a specific wireless modulation mode.
