基于OPC服务器的井下气体监测系统设计

his thesis describes the software and hardware of video node and sensor nodes for OPC server of underground fracture gas monitoring system in details. Design and implement environmental monitoring sensor nodes for real-time monitoring of tunnel deformation and delimitation during fracture equipment working, and monitoring the in concentration of gas (CO, H2S CH4 and O2) in the work environment. This paper discusses that for the problems in the underground multi-path interference and serious device's noise impact, the feasibility and the superiority of OPC technology applied to fracture monitoring system. According to the application background and needs analysis of underground fracture monitoring system, we design the network architecture of coiled methane fracture monitoring system. Finally, design of the OPC server in underground fracture monitoring system, which is used to provide a platform to build seamless connecting between the fracture monitoring system and the original network in coal, at the same time to better use existing enterprise network.
