The network device 102 is used to query the network status of the gateway in real time, and send configuration information of the gateway and data matching the communication protocol to the main control device 101.

The main control device 101 is connected to the wireless device 103 through a USB HOST communication method, and the wireless device 103 is used to transmit data through 4G, Bluetooth, and Wi-Fi.

The main control device 101 is connected to the bus bar 104 through a PCB wire.

The bus 104 is connected to the target device through a communication protocol to obtain sensing data.

Specifically, the bus 104 selects a communication protocol that matches the target device from the device driver library of the gateway 1; establishes a connection with the target device according to the matched communication protocol; obtains the target Perception data of the device; sending the perception data to the main control device 101.
