摘要:

针对煤矿系统的通信现状,提出利用TD-SCDMA技术构建井下无线网络的方案。通过对井下模拟巷道通信的实验研究,表明基于TD网络通信的可靠性,在此基础上设计并实现了基于TD-SCDMA技术的矿井无线数据采集终端。该终端选用TD终端模块LC6311(+)作为通信平台,给出其和单片机的接口通信电路,实现采集数据的快速、远距离传输,适合煤矿井下检测系统。

关键词: TD终端, 串口通信, AT指令, LC6311(+)

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(+)
