摘　　要：研究了一种适合煤矿井下工作特点的蜂窝无线通信系统.在巷道分叉和拐弯处,尽可能将基站布置在巷道的中央,可将蜂窝简化为条状通信网,并计算了越区切换概率.根据井下的特点,确定了条状通信网的越区切换准则.分析了现有常用的3种越区切换控制方式,结合井下工作的要求和本系统的特点,确定并设计了越区切换的控制方式.图3,参9.An underground cell communication system was presented.The cell system was simplified as strap network,if base stations were placed at the center of forked and curved channel.At such strap network,possibility of handover was calculated,and the rule of handover was determined.Popularly used methods of handover controlling were analyzed.According to the character of the underground communication system,the way of handover controlling which fits underground work demand was decided and designed.3figs.,9refs.
