【摘要】：煤炭资源是国民经济的命脉,矿井轨道运输在煤矿生产成本中占有非常大的比重。随着使用时间的增加,矿井轨道运输设备日益老化,从而导致轨道安全运输事故日趋严重。根据不完全统计,在煤矿生产过程中,轨道运输安全事故时有发生,约占矿井安全生产事故的13.5%,矿井轨道安全运输事故于越来越引起社会的关注。为保证矿井轨道运输安全,智能防跑车系统(国外也称之为防坠器、自动刹车器或减速器)在煤炭开采行业得到了广泛的应用。作为智能防跑车系统的核心部分,轨道矿车智能测速系统的性能是衡量智能防跑车系统可靠性的最重要参数之一。随着计算机控制技术的不断发展,越来越多的先进技术被应用到轨道矿车测速系统的设计中。本文在对现有的轨道矿车测速系统与几种常见矿车测速模型进行分析后,综合考虑了成本、可靠性、安全性、可拓展性等因素,把环形线圈引入到轨道矿车检测领域中来,将PLC作为现场采集与控制器,使用工业计算机与组态软件实现HMI(人机界面)的方案,共同组建轨道矿车运行状态的监控体系。主要工作有:1.对几种常用轨道矿车测速模型进行分析,选择本设计使用的测速模型。2.根据本设计使用的测速模型,结合轨道矿车测速的现场环境,对传感器进行选型,将并在此基础上进行系统整体构建。3.在系统整体方案确定的前提下,设计系统硬件部分进。研究环形线圈传感器对矿车的检测原理,分析影响检测精度的参数,针对分析结果,对环形线圈传感器进行适当改进。然后进行PLC和工业计算机的选型和接口分配,并根据系统功能需求设计PLC和工业计算机的电气连接方式。4.研究传感器单片机对矿车检测方法,完成单片机算法的编写。5.根据测速系统的功能需求,并完成PLC程序设计。6.根据系统所包含设备构建数据网络,并将数据集中至上位机,根据功能需求完成HMI(人机界面)的设计。结论:将环形线圈引用到该系统中用于矿车检测,使用PLC和组态软件参与系统的构建,使系统具有较好的应用价值。
[Abstract]:The coal resource is the lifeblood of the national economy, the mine rail transportation occupies the very big proportion in the coal mine production cost. With the increase of the use time, the mine rail transportation equipment is aging day by day. According to incomplete statistics, in the process of coal mine production, rail transportation safety accidents occur from time to time. About 13.5% of mine safety accidents, mine rail safety transportation accident has attracted more and more attention of the society. To ensure the safety of mine rail transportation, intelligent anti-sports car system (also known as anti-falling device abroad), Automatic brake or reducer) has been widely used in the coal mining industry. The performance of the intelligent speed measuring system of railway car is one of the most important parameters to measure the reliability of intelligent anti-sports car system. With the development of computer control technology, More and more advanced technologies have been applied to the design of the speed measuring system of rail cars. After analyzing the existing speed measurement system of rail cars and several common models, the cost, reliability and safety are considered comprehensively. In this paper, the loop coil is introduced into the detection field of rail car, and PLC is used as the field acquisition and controller, and the HMI (man-machine interface) scheme is realized by using industrial computer and configuration software. The main work of this paper is to analyze several commonly used speed measurement models of rail cars, and select the speed measurement model used in this design. 2. According to the speed measurement model used in this design, Combined with the field environment of track car speed measurement, the sensor is selected, and on this basis, the whole system will be constructed. 3. Under the premise of the determination of the overall scheme of the system, The hardware part of the system is designed. The detection principle of the loop coil sensor to the mine car is studied, and the parameters that affect the detection accuracy are analyzed. The loop coil sensor is improved properly. Then the selection and interface distribution of PLC and industrial computer are carried out, and the electrical connection mode of PLC and industrial computer is designed according to the functional requirements of the system. According to the function requirement of the speed measuring system and the PLC program design. The data network is constructed according to the equipment included in the system, and the data is centralized to the upper computer. The design of HMI (man-machine interface) is completed according to the functional requirements. Conclusion: the annular coil is used in the system for mining vehicle detection, and the PLC and configuration software are used in the construction of the system, which makes the system have better application value.
