结合田庄煤矿井下通信系统的现状,提出了一种煤矿井下撤人告警系统的设计方案,详细介绍了该系统各组成部分的工作原理、功能及实现方式,并以井下出现瓦斯事故为例对该系统的工作流程进行了说明。该系统基于数字广播扩音技术,以工业以太网为传输介质,可根据报警信息向井下各个工作面发出相应的预案告警信息,并可实现实时语音通话,为矿井抢险救援提供了可靠的技术手段。
Combining with the status quo of underground coal mine communication system in Tianzhuang Coal Mine, a design scheme of mine underground evacuation alarm system is proposed. The working principle, function and realization of each component of the system are introduced in detail. System workflow is described. The system is based on digital broadcasting technology and industrial Ethernet as the transmission medium. According to the alarm information, the system can send out corresponding plan alarm information to each working face downhole and realize real-time voice call, which provides a reliable technical means for mine rescue. .
