DESIGN AND EXPERIMENT OF AUTOMATIC MONITORING EQUIPMENT OF HARMFUL GAS IN SPACE

The harmful gas automatic monitoring device with the aid of 2 gas sensors can effectively monitor the concentration of harmful gas such as large gas storage space and large gas storage tanks. Once the concentration exceeds the limit value of the alarm,the alarm signal can be sent out,and automatically open the exhaust system to discharge the harmful gas from the outdoor. The main system of the device is described in detail,and the feasibility of the device is demonstrated by means of numerical simulation and experiment. The results show that the device has the advantages of low cost,convenient operation and high automation degree.
