Abstract:

According to the status of coal mine underground communication,a scheme of the underground wireless network is proposed.The feasibility of using TD-SCDMA technology through trial study of the simulation of tunnel in underground wireless communication is demonstrated,on the basis of which the mine wireless data acquisition Terminal based on TD-SCDMA technology is designed and implemented.The Terminal uses TD terminal module LC6311 (+) as the communication platform to realize fast,long-distance transmission of acquisition data,which is ideal for coal mine detection system.The interface communication circuit of the platform and MCU is also given.

Key words: TD-SCDMA terminal;serial communication;AT commands;LC6311(+)
