一种矿井下瓦斯安全监控预警系统
摘要：
本申请提供一种矿井下瓦斯安全监控预警系统，涉及瓦斯检测系统技术领域。本实用新型中包括检测装置、井下监控装置和井外监控装置；检测装置分别与井下监控装置和井外监控装置连接；井下监控装置和井外监控装置信号连接；所述检测装置包括瓦斯告警围栏和巷道顶板变形监测装置；瓦斯告警围栏和巷道顶板变形监测装置分别与井下监控装置和井外监控装置连接；瓦斯告警围栏包括两根并列设置的支撑架，两根支撑架之间设有护栏，支撑架上设有人体检测机构和声光报警装置，人体检测机构和声光报警装置电连接；当检测人员靠近告警烂时，告警栏上的声光报警装置会发出警报声音，起到了提示提醒的作用，保证了人身安全，使得矿井瓦斯安全监测得到显著改善。
摘要（英）：

The utility model provides an underground gas safety monitoring and early warning system, and relates to the technical field of gas detection systems. The system comprises a detection device, an underground monitoring device and an out-of-well monitoring device, the detection device is connected with the underground monitoring device and the out-of-well monitoring device. The underground monitoring device is in signal connection with the out-of-well monitoring device; the detection device comprises a gas alarm fence and a roadway roof deformation monitoring device. The gas alarm fence and theroadway roof deformation monitoring device are respectively connected with the underground monitoring device and the out-of-well monitoring device; the gas alarm fence comprises two supporting framesarranged in parallel, a guardrail is arranged between the two supporting frames, a human body detection mechanism and a sound-light alarm device are arranged on the supporting frames, and the human body detection mechanism is electrically connected with the sound-light alarm device. When a detection person gets close to the alarm fence and gets out of the alarm fence, the sound-light alarm deviceon the alarm fence can give out alarm sound to play a role in prompting and reminding, personal safety is guaranteed, and mine gas safety monitoring is remarkably improved.
