ZigBee技术无线瓦斯报警系统的设计与实现

ZigBee Design and Implementation of Wireless Gas Alarm System

摘要: 瓦斯泄露的检测与报警是煤矿开采安全生产中的重点监控对象。本文使用ZigBee无线通信模块组网技术和MQ-5的瓦斯浓度探测传感器与温湿度传感器设计并实现了无线瓦斯浓度报警系统。本无线瓦斯报警器系统，能够起到多节点瓦斯浓度采集、自动组网、远距离报警的作用。与传统的单点矿井瓦斯报警器相比，本报警系统使用电池供电具有布置灵活、低功耗、测量采集精度高、容灾性高等特点，可应用于煤炭井下开采的瓦斯浓度监控，可大大降低煤矿瓦斯爆炸的安全隐患。

Abstract: The gas leak detection and alarm is the most important coal mining safety production supervision and control object. This article uses the ZigBee wireless networking technology of communication module and MQ-5 gas concentration detection sensor with temperature and humidity sensors, designs and implements the wireless gas concentration alarm system. The wireless gas concentration alarm system can play multi-node capture, automatic networking and remote alarm roles. Compared with the traditional single-point mine gas alarm, the alarm system has the characteristics such as flexible layout, low power consumption, high accuracy measurement acquisition, disaster tolerance and so on. It can be applied to the gas concentration monitoring in the coal mine and can greatly reduce the gas explosion.
