水泵自动化控制系统论文：煤矿井下排水自动控制系统的研究 【中文摘要】煤炭产业是我国的支柱产业之一,在国民经济中占有重要的位置。在煤炭企业发展的同时,煤矿安全问题日益突出。作为煤炭生产中的主要工作系统之一,煤矿井下排水问题在煤矿安全问题中占有举足轻重的地位,矿井涌水如果不能及时排除,将极大地威胁煤炭生产和井下工作人员的生命安全。但是,目前我国大多数矿井排水仍采用传统的继电气控制方式,这种系统自动化程度低,应急性不高,存在很大的安全隐患,不能适应当今煤炭行业飞速发展的要求。本课题针对现有矿井排水的弊端,研究了适应于我国矿井排水现状的煤矿井下主排水控制系统,该系统以欧姆龙公司生产的CJ1G-42H为主控制器,并且扩展了必要的模拟量输入单元,通信单元,数字量输入输出扩展单元。本系统设计为三种主要控制方式—自动,半自动,手动。其中半自动方式又分为两种:半自动触摸屏集控和半自动调度室集控。在这四种方式之间可以自由切换,在自动控制方式下,可以实现在线实时的检测水仓水位,自动起停水泵,故障自动报警等。井下排水系统耗电量大,运行成本高,本系统在模糊控制理论的基础上将矿井排水控制系统与之相结合,根据用电的“避峰就谷”自动确定启动水泵的台数,以达到优化控制进而降低生产成本的。本系统通过使用工业以太网,将井下数据传输到地面监控室。上位机采用Ifix软件,实时对井下水泵情况进行远程监测和控制。 【英文摘要】The coal industry is one of the pillar industries in China, which places an important role in the national economy. Meanwhile, the safety production of coal has become an increasingly prominent problem. As one of the main working systems of coal production, underground mine drainage has a very important status in the coal safety production. However, most coalmines of China today still use the traditional relay control drainage system, which can not meet the development of China抯 coal industry because it has a big risk for its low degree of automatic and slow emergency response.This essay analyzes the disadvantages of existing underground mine drainage systems and studies the controller of the fittest underground mine drainage system for China’s mines. The system uses CJ1G-42H made by Omron Corporation as the master device, together expands the controller with necessary analog inputs unit、communication units and digital inputoutput expansion unit. The system is designed to three main control modes: automatic, semi-automatic and manual operation. Among the three modes, the semi梐utomatic is divided into two styles: semi-automatic touch screen set control and semi-automatic controlling room set control. All those four modes can shift freely within the system. When the system is on automatic mode, it can not only detect the water storehouse level but can also automatic alert when
