Research on Gas Monitoring Essential Technique and Equipment for Underground Mobile Equipment in Collieries

The gas monitoring system for underground mobile vehicles in collieries uses embedded system,ZiGBee wireless technology,sensor technique and so on.The mobile device can display and real-time monitoring gas concentration,at the same time transporting data to the fixture which can record data and form the historical curve for the analysis need.If the gas concentration exceeds safety settings,the system sends out the alarm with sound and light,and touching the relay on the outage and power atresia of large mobile equipment.When the gas content is drop to the following standards,the equipment can restore production after automatic power reset,and therefore the gas accident avoids effectively.
