And the application of the wireless communication technology can realize wireless data transmission between devices without complicated wiring work. For this reason, wireless communication technology is used in the prior art to transfer data between electronic devices. But in transmitting signals by wireless transmission, it can only transmit signals in a single mode. For example, 485 communication requires a differential signal circuit (a/B line) and half-duplex control logic, analog quantity requires special signal conditioning and analog-to-digital conversion circuits, switching quantity requires digital input and output and photoelectric isolation circuits, and hardware cannot simultaneously support the electrical characteristics of three signals, and only one signal processing channel can be activated at the same time. In addition, when data transmission is carried out, the 485 module is designed to be transparent to transmit serial data flow, the analog quantity module needs to digitize and then transmit continuous signals, the switching quantity needs state detection and coding, is incompatible with 485 data packet format, and the conversion mechanisms of the three signals are mutually exclusive and cannot be processed in parallel. In addition, the communication protocols of the signals in the plurality of modes are different in communication.
