【摘要】：煤炭作为我国能源生产和消费的主要一次能源,所占的比例一直在70%左右。随着国民经济的不断发展,无论是工业生产还是人民生活,对于煤炭的需求量依然是逐渐增加的。以煤炭作为主要生产和消费的能源格局,在将来相当长的一段时间内是不会改变的。空压机作为煤炭生产中非常重要的一部分,它的稳定性能对于煤炭的安全生产起着重要的作用。论文以某矿集团某矿“空压机检测与控制系统”为背景对空压机检测与控制系统中不同部件,所使用不同类型传感器进行了详细比较分析,分别对排气温度、排气压力、电动机过载、电动机电压、电流检测、电动机振动等项目进行检测与保护的传感器进行了详细比较,并最终确定了其传感器型号。针对矿井空压机PLC控制系统设计,通过比较分析,最终选用西门子公司14输入10输出的S7-200系列224XP的PLC。详细分析和设计了采用传感器对空压机各种参数进行采集,并通过PLC、触摸屏和组态软件对空压机进行检测和控制的基本原理和方法。利用传感器与保护元件对现场各种参数的收集,结合通信技术,针对原有的空压机继电器控制系统存在的不足,提出了基于PLC、触摸屏和组态软件相结合的空压机改进系统,即实现空压机智能化。对于矿井的安全生产提供了更为方便、简洁、安全、可靠的空压机操作系统。
[Abstract]:As the main primary energy of energy production and consumption in China, coal accounts for about 70%. With the development of national economy, the demand for coal is still increasing. Coal as the main production and consumption of energy pattern, in the future for a long period of time will not change. As a very important part of coal production, air compressor plays an important role in the safety of coal production. Based on the "air compressor detection and control system" of a certain mine group, this paper compares and analyzes the different parts of the air compressor detection and control system and the different types of sensors used in the air compressor detection and control system in detail. The exhaust temperature and pressure are analyzed respectively. The sensors used to detect and protect motor overload, motor voltage, current detection and motor vibration are compared in detail, and the type of sensor is finally determined. According to the design of PLC control system of mine air compressor, through comparison and analysis, the PLC of S7-200 series 224XP, which is 14 input and 10 output from Siemens Company, is finally selected. The basic principle and method of measuring and controlling air compressor by means of PLC, touch screen and configuration software are analyzed and designed in detail. Based on the collection of field parameters by sensors and protection elements, combined with the communication technology, an improved air compressor control system based on PLC, touch screen and configuration software is proposed, aiming at the shortcomings of the original air compressor relay control system. That is to achieve intelligent air compressor. It provides a more convenient, simple, safe and reliable air compressor operating system for mine safety production.
