司马煤业井下信息无线通信系统的优化研究

Research and Optimization of Underground Information Wireless Communication System in Sima Coal Mine

针对司马煤业采用小灵通无线通信技术所存在的通信效率低、稳定性差的问题,提出了一种新的4G双模通信系统,充分利用现有的数据通信网络,开发了新的基站控制器(BSC)、室外LTE基站及双模防爆模块,实现了井下无线通信技术的升级。根据在司马煤业的实际应用表明,新的数据通信系统将数据通信效率提升了4倍以上,彻底消除了各个数据系统之间的信息“孤岛”。

Aiming at the problems of low communication efficiency and poor stability when Sima Coal Industry adopts PHS wireless communication technology,a new 4G dual-mode communication system is proposed.Making full use of the existing data communication network,a new base station controller(BSC),outdoor LTE base station and dual-mode explosion-proof module are developed,and the underground wireless communication technology is upgraded.According to the practical application in Sima Coal Industry,the new data communication system increases the data communication efficiency by more than 4 times,and completely eliminates the"isolated island"of information between various data systems.
