视频监控系统是井下作业安全的有力保障,在煤炭生产中有越来越广泛的应用。而带式输送机作为煤矿运输中的重要设备,也需要纳入监控系统中。提出了一种经济可靠的监控方案,采用基于以太网的防爆摄像仪,并在以太网拓扑上提出独到方案,在保证系统技术先进性的同时,也使得成本得到进一步的控制。此系统已在山西王家岭矿完成,经证明,实施简单方便,网络可扩展性高,兼容性强,信号传输可靠稳定。
Video surveillance system is a powerful guarantee for the safety of underground operations, and has more and more widespread applications in coal production. The belt conveyor as an important transport equipment in the mine, but also need to be included in the monitoring system. An economical and reliable monitoring scheme is proposed. The explosion-proof camera based on Ethernet is put forward and a unique scheme is proposed on the Ethernet topology. This ensures that the advanced technology of the system can be realized and the cost can be further controlled. This system has been completed in Shanxi Wangjialing Mine, which has been proved to be simple and convenient to implement with high network scalability, strong compatibility and reliable and stable signal transmission.
