【摘要】：矿井提升机常常被称作矿山的咽喉,其控制水平和可靠性直接影响到煤矿企业的日常生产与安全,是当前国内各大煤矿企业普遍遇到的问题之一。目前提升机的控制大多采用传统的继电器-转子串电阻的方式,已经严重影响了煤矿企业连续大产量生产的要求,同时煤矿安全可靠性极低,人身伤亡事故频发。当今,采用可编程控制器和专用运动控制器对提升机进行速度和行程准确控制,已经成为提升机系统的重要发展方向。本文研究了基于FM458模块的矿井提升机的自动化控制系统,主要工作如下：首先,介绍了当前提升机系统的研究背景与意义,从行程控制、安全可靠性、系统监视、传动系统等方面对比了国内外提升机控制系统的研究现状,分析了相关特点。其次,介绍了提升机的工作过程及煤矿企业对自动化控制系统要求,就当前提升机自动化控制系统的速度图曲线进行了分析,针对现有模型存在的人员乘坐舒适感及系统控制扰动问题,提出了S形对称7阶速度曲线模型,给出了速度与位置控制算法,对提升机的工艺系统、控制系统及配套电气传动设备进行阐述。在此基础上,给出了提升机自动控制系统的硬件与软件设计,其中硬件部分包括主控系统及运动控制系统的模块选型,现场检测仪表、操作台及上位机的配置,软件部分包括主程序安全监控系统、运动控制系统模块的功能设计。并针对具体的功能模块,给出了相应的程序流程图及功能图。基于WinCC Flexible软件和STEP 7编程软件给出了系统的具体实现。最后,基于PLC-ANALYZER软件模拟出了S形对称7阶速度曲线。系统测试结果证明,该自动控制系统能够完全满足煤矿企业提出的总体任务要求,乘坐舒服度高,控制精度满足误差要求。煤矿矿井提升机自动化控制系统已经成功运用在山西某国有大型煤矿,于2015年2月正式投入运行。该系统研制成功,极大地提高了该煤矿企业的生产能力,同时有效地避免安全事故的发生。本课题的设计方法也可以应用到其他矿井工程如金矿、铜矿矿井提升机系统设计中。
[Abstract]:Mine hoist is often called the throat of mine. Its control level and reliability directly affect the daily production and safety of coal mining enterprises. At present, the control of hoist mostly adopts the traditional relay-rotor series resistance, which has seriously affected the requirement of continuous large output production in coal mining enterprises, and at the same time, the safety and reliability of coal mine is very low, and the accidents of personal injury and death occur frequently. Nowadays, the use of programmable controller and special motion controller to accurately control the speed and stroke of hoist has become an important development direction of hoist system. In this paper, the automatic control system of mine hoist based on FM458 module is studied. The main work is as follows: firstly, the research background and significance of current hoist system are introduced, including stroke control, safety and reliability, system monitoring, etc. The research status of hoist control system at home and abroad is compared, and the related characteristics are analyzed. Secondly, the paper introduces the working process of hoist and the requirements of coal mine enterprises for automatic control system, and analyzes the speed diagram curve of the current automatic control system of hoist. Aiming at the problems of comfort and system control disturbance in the existing models, a S-shape symmetric 7-order speed curve model is proposed, and the speed and position control algorithm is given, and the process system of the hoist is analyzed. Control system and supporting electrical transmission equipment are described. On this basis, the hardware and software design of the hoist automatic control system is given. The hardware part includes the module selection of the main control system and the motion control system, the field detection instrument, the configuration of the operation table and the upper computer. The software part includes the main program security monitoring system and the function design of motion control system module. According to the specific function module, the corresponding program flow chart and function diagram are given. Based on WinCC Flexible software and STEP 7 programming software, the implementation of the system is given. Finally, the S-shape symmetric 7 th order velocity curve is simulated based on PLC-ANALYZER software. The system test results show that the automatic control system can fully meet the overall task requirements of coal mining enterprises, high ride comfort, control accuracy to meet the error requirements. The automatic control system of coal mine hoist has been successfully used in a large state-owned coal mine in Shanxi Province, which was formally put into operation in February 2015. The successful development of the system greatly improves the production capacity of the coal mine enterprise and effectively avoids the occurrence of safety accidents. The design method of this subject can also be applied to other mine engineering such as gold mine and copper mine hoist system design.
