矿井调度移动通信系统有关问题的研究

The Study of Some Related Problems of the Communication System of Mine Managing Mobile

研究了小区制矿井调度移动通信系统所涉及的有关问题。综合考虑有关因素对无线传输的影响以及矿井巷道与系统配置的实际情况确定了系统的工作频率、基站与移动台天线形式 ;根据系统的话务情况与特点确定了系统采用多信道共用技术以及相应的共用信道数、信道指配原则、信道指配模式、信道选取原则和系统的呼叫方式 ;根据井下实测初步确定了系统的小区半径以及大、中和小型矿井实现全矿井调度移动通信所须配置的小区数量。

Some related problems of mine managing mobile communication system consisted of minute areas are studied. The system frequency and antenna mode are decided,considering the influence of some factors and the actual instances of underground tunnels and system configuration to the wireless transmission. The shared channel technology and the shared corresponding channel number, channel assignment principle, channel selection pattern and the calling mode are decided according to the communicative requirement and specialty of the system. Based on the underground actual measurement,the radius of minute areas is confirmed elementarily so the number of minute areas for big, middle and small mines can be confirmed.
