一种基于扩频通信的煤矿通信系统及其应用

Mine communication system and its application based on spread communication

简述了煤矿系统的通信现状,介绍基于直接扩频通信理论的扩频通信芯片SC1128及其通信系统,该系统具有结构简单、误码率低、准时性和可根据实际通信的需要通过对软件中的参数进行重新设定等优点,特别适合煤矿通信,并且在试验的基础上证实了SC1128系统在煤矿通信中应用的可行性,指出可行的具体方案:在主巷道使用漏泄电缆,而在其它巷道采用扩频通信。

It sketches current application of the Colliery communication system,Recommends emphatically communication chip SC1128 ,which is based on direct expanding communication theory and its communication system, This system is of simple structure, mistaken code rate is low , 100% punctuality and the parameter can be established again through parameter in software according to the needs of actual communication and etc Which especially suits mine communication .The feasibility is verified that SC1128 systems are used in the low voltage power line communication system on the basis of testing. Point out the feasible concrete scheme: Use the leadage cable in the main tunnel, but adopt spread spectrum communication in other tunnels.
