China as an energy superpower, in mine safety monitoring this is particularly important, in the traditional way of cable used communication cable has a lot of disadvantages. First underground large mechanical movement to cause interruption of communication cable rupture. Second downhole environment wiring is a thinking and for a large number of communication cable network problems Considering the flexibility of underground cable data acquisition device of traditional way more bad of the premise, also considering the advantages of wireless transmission is proposed in this paper, based on ZigBee wireless transmission of downhole data acquisition, the design adopts double STC12C5A60S2 of single-chip microcomputer serial communication, through a serial port 1 control ZigBee passthrough module can be transmitted to the computer terminal display, serial port 2 is used to control the laser ranging module for various measurement devices returned data. System overall scheme is: at the beginning of the PC for testing instructions; Terminal response to address; PC send address; Serial port 1 received data for its own address, and start a measurement task, or enter a dormant state; Finally PC response data and processing. The design points based on transmission line underground station the functions can be real-time response whether underworkings appears to be out of shape.
