【摘要】：当今时代经济迅速发展,在我国产业结构调整过程中,重工业仍需打好坚实的基础,煤炭作为重工业的能源基础,需求量巨大,因此担任煤炭外运工作的选煤厂装车站格外重要。随着工业控制技术和管理水平的提高,尤其是计算机系统、PLC集中控制、传感器检测等技术的快速发展,对装车平煤系统提高了要求,传统的装车平煤的控制管理工艺急需进行改进、调整。本文依据现代技术手段,遵循选煤厂装车平煤控制要求,以山西阳泉阳煤二矿选煤厂装车站为研究对象,对选煤厂装车平煤自动控制与检测开展研究。深入分析煤炭装车过程和平煤破坏机理,讨论装车工艺存在问题,提出装车平煤结构调整方案。同时,采用了先进的视觉检测、PLC控制和组态界面等技术,解决原装车站人工操作过程中精度差、操作繁琐、效率低下、人工劳动强度大、施工条件差和危险度高的情况。本文在解析装车工艺和控制手段不足的基础上,全面描述了自动装车平煤系统的组成和控制方案。主要完成工作为:利用计算机图像识别技术,建立定量辅助装煤视觉检测系统,避免放煤过多或不足;设计煤炭标识自动喷洒装置;利用可编程控制软件(PLC)与传感技术实现装车平煤与喷洒装置的自动控制;通过MCGS组态软件建立装车平煤现场组态控制界面,实现实时监控并记录装车信息。最终建立自动装车平煤控制系统,能在装车过程中实现自动定位、定量装车、数据采集、顺序控制、运行监控等各项工作,达到精确装载、快速装载。
[Abstract]:With the rapid economic development of the times, heavy industry still needs to lay a solid foundation in the process of industrial structure adjustment in our country. As the energy base of heavy industry, the demand for coal is huge. Therefore, it is particularly important to take charge of the coal preparation plant installation station. With the improvement of industrial control technology and management level, especially the rapid development of computer system PLC centralized control, sensor detection and other technologies, the requirements of coal loading system have been raised. The traditional control and management technology of coal loading is in urgent need of improvement and adjustment. According to the modern technical means and in accordance with the control requirements of coal preparation plant, this paper takes the loading station of Yangquan No. 2 Coal preparation Plant in Yangquan, Shanxi Province as the research object, and carries out the research on the automatic control and detection of the level coal loading in the coal preparation plant. This paper analyzes deeply the mechanism of coal destruction in coal loading process, discusses the problems existing in loading process, and puts forward the adjustment scheme of coal loading structure. At the same time, advanced visual inspection PLC control and configuration interface technology are adopted to solve the problems of poor precision, cumbersome operation, low efficiency, large labor intensity, poor construction conditions and high dangerous degree in the manual operation of the original station. On the basis of analyzing the shortage of loading technology and control methods, this paper describes the composition and control scheme of the automatic loading and leveling coal system. The main work is as follows: the computer image recognition technology is used to establish a quantitative auxiliary coal loading visual detection system to avoid excessive or insufficient coal drawing, and the automatic spraying device for coal marking is designed. The automatic control of coal loading and spraying device is realized by PLC and sensing technology, and the field configuration control interface of loading level coal is established by MCGS configuration software to realize real-time monitoring and recording loading information. Finally, the automatic coal loading control system is established, which can realize automatic positioning, quantitative loading, data acquisition, sequence control, operation monitoring and so on, so as to achieve accurate loading and fast loading.
