基于移动互联的煤矿通风机远程监控技术

Ventilator remote monitoring technology of coal mine based on mobile Internet

针对目前煤矿通风机采用冷备用方式及供电系统采用单母线分段运行方式存在安全隐患的问题,介绍了在通风机不停风倒机控制、风门设计、通风机供电安全、通风机监控系统冗余、通风机故障诊断等方面所做的研究,研究成果的应用提高了煤矿通风机的安全运行水平和自动化程度;针对通风机房位置偏远、容易陷入信息孤岛的问题,采用移动互联相关技术,构建了基于移动互联的煤矿通风机远程监控系统,着重介绍了该系统移动客户端的功能设计及基于Socket通信的客户端和服务器端程序设计。该煤矿通风机远程监控系统采用GPRS-DTU模块从PLC采集数据,通过GPRS网络将监控数据上传至基于PC的数据服务中心,并通过数据服务中心与移动客户端的Socket通信,实现随时随地的通风机远程监控功能。

For hidden danger caused by cold standby mode of co segmentation operation mode of power supply system at present, a serie al mine ventilator s of research work and single bus were introduced about switchover without blowing-out of ventilator, air door design, power safety of ventilator, redundancy of ventilator monitoring system, fault diagnosis of ventilator, etc. Application of corresponding research achievements improves safe operation level and automation degree of coal mine ventilator. Since ventilator room locates on remote places and ventilator monitoring system is easy to failing into information isolated island, a remote monitoring system of coal mine ventilator based on mobile Internet was built by use of corresponding mobile Internet technologies. Function design of mobile client of the system and program design of client and server based on Socket communication were introduced in details. The system collects data from PLC by use of GPRS-DTU module and uploads the data to server through GPRS network, which realizes remote monitoring function of ventilator anytime and anywhere through Socket communication between server and mobile client.
