Study on the application of Zigbee in monitor system for coal mine

Traditional lineate monitor systems in coal mine can not meet the need as the modernize production developing, because they are difficulty to lay, dangerous and are difficulty to supply power. A new idea is studied in this article: using a new communication technology called ZigBee combined with the lineate communication to build a monitor system. This system is a wireless network which can detect the sensitivity parameters in coal mine, and then the parameters are transmitted to control room through cables, this can help people get the safety state in mine.
