【摘要】：本课题来源于晋城煤业集团科技申报项目“矿井主排水自动化监控系统的开发”(No.20100819-2),是针对当前我国矿井主排水自动化系统控制技术落后、故障率高、可靠性差等问题而提出的。井下排水系统是煤矿四大生产系统之一,担负着井下涌水排除的重要任务,其能否正常运行直接影响着整个矿井的安全生产。目前,国内多数矿井仍采用继电器控制方式,该方式以人工手动控制为主,因而水位检测精度不高,操作随意性大,无法实现涌水量的实时监测和排水过程的科学调度。另外,国内少数煤矿已采用了自动化排水装置,但其故障率高、可靠性差、控制功能不健全,不能满足无人值守自动化排水要求。因此,研发功能齐全、可靠性高的煤矿无人值守自动化排水系统对实现煤矿生产自动化具有重要的现实意义。本文对寺河矿原有主排水系统进行了详细调研,深入理解并分析其工作原理,查阅国内外相关资料和文献,结合任务书要求,确定了矿井主排水监测监控系统的总体方案,采用上位机结合下位机的二级控制网络结构,上位机置于地面调度室,下位机置于在井下泵房,两者有机结合,共同完成自动化排水任务。根据系统控制结构,设计了矿井主排水监测监控系统的硬件电路,主要包括信号采集层、电控箱、操作台及通讯网络等,并配置了地面监控中心的硬件结构。经实验室测试和现场调试,验证了硬件方案的合理性和有效性。根据系统的设计要求,结合硬件电路特点,设计了主排水监测监控系统的应用软件,应用软件分为下位机软件和上位机软件两部分。下位机软件以PLC程序和人机界面程序为核心,具有数据采集、实时监测与控制、人机信息交互、故障报警等功能。上位机软件基于6.55版组态王软件平台和Microsoft Office Access数据库进行开发,可实现对井下上传的运行数据、操作记录、故障报警等信息的存储、统计和分析,并具有远程控制井下设备的功能。在实验室搭建了系统试验平台,对排水监测监控系统各单元进行了硬件、软件调试以及系统整体调试,最后在晋煤集团寺河矿东井区+350中央泵房进行了现场工业应用。系统运行结果表明：系统整体结构合理,硬件电路精度高、抗干扰性强；下位机软件设计合理、扩展方便、运行快速可靠、控制功能完善；上位机软件人机交互性良好、画面简洁、内容丰富、功能齐全、监测数据实时准确；整个系统运行稳定,各项指标均达到了设计的要求,能够满足现代煤矿井下排水需求。
[Abstract]:This subject originates from the project of Science and Technology Application of Jincheng Coal Industry Group, "the Development of Mine main drainage Automation Monitoring system" No. 20100819-2, which is put forward in view of the problems of backward control technology, high failure rate and poor reliability of mine main drainage automation system in our country at present. The underground drainage system is one of the four production systems in coal mine, which is responsible for the important task of removing the underground water gushing, and its normal operation directly affects the safety production of the whole mine. At present, relay control is still adopted in most mines in our country, which is mainly manual control, so the precision of water level detection is not high, the operation is arbitrary, and it is unable to realize the real-time monitoring of water discharge and the scientific dispatch of drainage process. In addition, a few coal mines in China have adopted automatic drainage devices, but their failure rate is high, their reliability is poor, their control function is not perfect, and they can not meet the requirements of unattended automatic drainage. Therefore, the research and development of coal mine unattended automatic drainage system with complete function and high reliability has important practical significance to realize the coal mine production automation. In this paper, the original main drainage system of Sihe Coal Mine is investigated in detail, its working principle is deeply understood and analyzed, relevant materials and documents are consulted at home and abroad, and the overall scheme of mine main drainage monitoring and monitoring system is determined in combination with the requirements of the task book. The secondary control network structure of the upper computer combined with the lower computer is adopted. The upper computer is placed in the ground control room and the lower computer is placed in the underground pump room. Both of them are combined organically to accomplish the task of automatic drainage together. According to the control structure of the system, the hardware circuit of the mine main drainage monitoring and monitoring system is designed, including the signal collection layer, the electronic control box, the operation table and the communication network, and the hardware structure of the ground monitoring center is configured. The rationality and validity of the hardware scheme are verified by laboratory test and field debugging. According to the design requirements of the system and the characteristics of the hardware circuit, the application software of the main drainage monitoring and monitoring system is designed. The application software is divided into two parts: the lower computer software and the upper computer software. The software is based on PLC program and man-machine interface program. It has the functions of data acquisition, real-time monitoring and control, human-computer information interaction, fault alarm and so on. The upper computer software is based on the 6.55 version of Kingview software platform and Microsoft Office Access database. It can store, statistics and analyze the operation data, operation record, fault alarm and so on. And has the function of remote control of underground equipment. The system test platform was set up in the laboratory, and the hardware, software and the whole system were debugged for each unit of the drainage monitoring and monitoring system. Finally, the field industrial application was carried out in 350 central pump room of Donghe well area of Jinmei Group Sihe Coal Mine. The results of system operation show that the system has reasonable structure, high precision of hardware circuit, strong anti-interference, reasonable design of lower computer software, convenient expansion, fast and reliable operation, perfect control function, good man-machine interaction of upper computer software, The picture is simple, the content is rich, the function is complete, the monitoring data is real time accurate, the whole system runs stably, each index has reached the design request, can satisfy the modern coal mine underground drainage demand.
