【摘要】 煤炭是重要的能源之一，煤炭工业生产的自动化、信息化发展，是国家生产力发展水平一个重要标志。煤炭工业的发展是与其依靠科技进步，采用新设计，新工艺、新设备、新材料、新技术来改造这一传统产业是分不开的，而开发和应用电子技术、计算机及自动化技术是煤炭工业技术改造的一个重要方面。 随着计算机控制技术的迅速发展，以微处理器为核心的可编程序控制器(PLC)控制已逐步取代继电器控制，普遍应用于各行各业的自动化控制领域。煤炭行业也不例外，但目前煤矿井下排水系统仍多采用继电器控制，水泵的开停及选择切换均由人工完成，还做不到根据水位或其它参数自动开停水泵，这将严重影响井下排水泵房的管理水平和经济效益的提高。 一座现代化煤矿年生产能力都在1000万吨左右，井下涌 太原理工大学硕士研究生学位论文水量较大，井下中央泵房设有大型水仓，巷道和采区分布有众多小型水仓通过管道向中央水仓排水，中央泵房通过多台主排水泵(以3台为例)，配套电动机一般功率较大，几趟排水管路。正常涌水时，1台工作，1台备用，1台检修。其它水仓一般设一台水泵向中央水仓排水，功率较小。鉴于PLC的先进性和可靠性，本文设计隔爆兼本安型测控仪对分布水仓水泵及主排水泵装置实施PLC自动控制及运行参数自动检测，动态显示，并预留通讯接口可将数据传送到地面生产调度中心，进行实时监测及报警显示。 隔爆兼本安型测控仪通过检测水仓水位和其它参数，控制水泵轮流工作与适时启动备用泵，合理调度几台水泵运行。如果通过预留通讯接口将其组成系统，将隔爆兼本安型测控仪采集的各种参数传往地面监控中心，可以通过触摸屏以图形、图像、数据、文字等方式，直观、形象、实时地反映系统工作状态以及水仓水位、电机工作电流、电机温度、轴承温度、排水管流量等参数，并能与矿井综合监测监控主机实现数据交换。系统具有运行可靠、操作方便、自动化程度高等特点，并可节省水泵的运行费用闭。 传感装置是自动化系统得以实现的关键。从现场情况看， II 太原理工大学硕士研究生学位论文除少数传感器应用较好外，多数传感器的性能不稳定、可靠性差、使用寿命不长，因此也影响了自动化系统作用的发挥。本文在传感器的开发中，为适应计算机、自动化技术的发展，为提高传感器的性能，实现了误差和非线性的修正、环境因素影响的抑制、自诊断和自动校正功能、灵活的显示和输出方式等〔3:。 本文的研究成果对充分利用现代信息技术，加速实现煤炭工业的信息化，以达到信息资源共享，提高管理水平有着重要的意义。同时将对煤矿高产、高效、安全、优质、减人提效发挥更大的促进作用。更多还原

【Abstract】 Coal is the one of the important sources. The automatization of the coal industry production and the development of information are the important symbol of the productivity development level. The development of coal industry has in close touch with new design, new arts and crafts, new equipment, new material, and new technique. However, the electron of exploitation and the application of computer and automatization technology are very important aspect of coal industry technology reconstruct.As the rapid development of computer control technology, PLC, which bases on microcomputer, has taken the place of relay control technology by and by; it is widely used in the automatization area in every walk of life, including the coalindustry. But at present most of the drainage systems in coal mine are still controlled by relay control system, the on and off and switch of water pump are operated by workers, it can’t switch on and off the pump automatically according to the water level and other parameters, it affects the management level of primary water pump house and economic benefits seriously.The production of a modern coal mine is about ten million tons annually, the hydranlic discharge in mine is abundant, the central pump house is equipped with big water bunker, in laneways and excavation area there are many small water bunkers pump water to the central bunker by pipes; in central pump house there are several primary pumps (for example 3), the matched motor is above 1250KW generally, and there are several drainpipe lines. When the hydranlic discharge is normal, one work, one standby, and another one for preparation. Other water bunker in general has one pump-to-pump water to the central bunker; the power of the pump is relatively small. Depending on the advancement and reliability of PLC, this essay shows a design of flameproof intrinsically safe detector and controller,which implements the PLC control over the pump in the distributed water bunker, primary pump, the vacuumizing system and the electric valves in the pipe attached to it, it detects the run parameters automatically.It can display dynamically, and it obligates communication interface, which will transmit the date to the production attemper center on the ground, it can implement the function of real-time inspection, alarm and display. The flameproof intrinsically safe detector and controller controls the pump to work alternatively and starts the standby pump timely, it attempers several pump to work reasonably. If the system is built up by the obligate communication interface, various of parameters collected by the flameproof intrinsically safe detector and controller is transmitted to the inspection center on the ground, then the finger, photo, data, and text on the touch screen can reflect the status of the system, the water level, the current and temperature of the motor, the temperature of the bearings, and the flux of the drainpipe, and it can exchange the data with the mine synthesis detection and control host computer, working reliably , operated easily, andhighly automatized are features of the system ,it also cuts down the run fee of the pump.Sensors are the key to the realization of the automation system, in local situation, except some sensors work well, the performance of most sensors is not stable , their reliability is low, the longevity of service is not long, these factors will affect the function of automation system. In this essay, in the exploitation of sensor, in order to adapt to the development of computer and automation technology, to improve the performance of the sensor, the new design can amend the error and non-linear, it can restrain the influence of the environment factors, it can implement the function of self detection and self adjustment, it has a flexible mode of display and output.this essay has important meaning in making the best of the modern information technology, speeding up to informize the coal industry, sharing the information resource, improving the level of management.
