ZigBee无线自组网测温技术在矿山火灾预警中的应用

On the Application of ZigBee Wireless Ad Hoc Network Temperature Measurement Technology in Early Warning of Mine Fire

煤田火区严重威胁着周边矿井的安全生产,利用ZigBee无线自组网技术与温度传感器相结合的测温方法,构建煤田火区监测网络,其单个结点成本低、功耗小,可在野外无交流供电状况下长时间运行。该技术可将煤田火区的温度信息实时地上传给矿山火灾监测预警部门,随时掌握矿山周边煤田火区的发展变化趋势,为有效防治矿井火灾提供决策依据,保证矿山的安全生产。

Fire district of coal field seriously threatens the safety in production of surrounding mines. As using temperature measurement method that combines ZigBee wireless ad hoc network technology with temperature sensor to build monitoring network for fire district of coal field has advantages of low cost of single node and low power dissipation, it can be in motion in the wild for a long time without alternating current supply. The technology can realize real-time upload of temperature information of fire district of coal field to the monitoring and early warning department of mines fire, control development and variation tendency of the surrounding fire districts of coal field of the mine, provides decision-making basis for effective prevention and control of mine fire, and ensures the safety in production in mine.
