The invention relates to a transparent transmission and wireless communication system for an industry. A wireless communication module comprises a dial switch, a power module, and an RS485 module, a 51 single chip microcomputer module, a radio frequency module and a wireless transmitting and receiving controller mutually connected in sequence, wherein the power module provides power for the RS485module, the 51 single chip microcomputer module and the radio frequency module; the dial switch is connected with the 51 single chip microcomputer module; the wireless transmitting and receiving controller of the wireless communication module located on an intelligent instrument device is connected with a first antenna, and the RS485 module communicates with the intelligent instrument device; thewireless transmitting and receiving controller of the wireless communication module located on a data stack is connected with a second antenna, and the RS485 module communicates with the data stack; and the gain of the first antenna is smaller than that of the second antenna. The system integrates transmitting and receiving, remote and transparent transmission is realized, the system is not restricted by the distance, the generality is strong, and the use is flexible.
