尽管我国是煤炭大国,可说到安全生产问题,和发达国家的差距还是很大的。文章针对煤矿的安全生产设计了一个基于无线传感器网络的监测系统,其中包括了环境监测和人员定位两个子系统,该系统的设计为煤矿安全生产提供了极大的保障。 Although our country is a big coal country, we can talk about the issue of safe production and the gap with developed countries is still huge. This paper designs a monitoring system based on wireless sensor network for coal mine safety production, including two subsystems of environmental monitoring and personnel positioning. The design of the system provides great protection for coal mine safety production.
