Cooperative control system for closed goaf

The utility model relates to a closed goaf cooperative control system which comprises a host, an intrinsic safety type controller, a nitrogen injection valve, an extraction valve, an extraction pipeline monitoring unit, a nitrogen injection pipeline monitoring unit and a differential pressure and environment monitoring unit. The intrinsic safety type controller is connected with the nitrogen injection valve, the extraction valve, the extraction pipeline monitoring unit, the nitrogen injection pipeline monitoring unit and the differential pressure and environment monitoring unit. The closed goaf cooperative control system achieves closed goaf micro-positive pressure control, effectively prevents goaf air leakage, prevents return airway gas overrun, has the effect of controlling goaf spontaneous combustion, and has very important significance. 本实用新型涉及一种密闭采空区协同控制系统，包括主机、本安型控制器、注氮阀门、抽采阀门、抽采管路监测单元、注氮管路监测单元、差压与环境监测单元，主机与本安型控制器相连，本安型控制器分别与注氮阀门、抽采阀门、抽采管路监测单元、注氮管路监测单元、差压与环境监测单元相连。该密闭采空区协同控制系统实现密闭采空区微正压控制，有效防治采空区漏风，防治回
