论文中文摘要: |
煤矿有两种运输方式,一种是主运输,另一种是辅助运输,其中辅助运输又分为轨道辅助运输和无轨辅助运输两种。轨道辅助运输以悬吊单轨和铺设双轨为主要特征;无轨辅助运输以机动车辆为主要特征,其中胶轮车运输是无轨辅助运输的其中一种,目前我国的许多新型煤矿采用这种运输模式,但是由于煤矿成本与井下工作空间的限制,辅助运输巷道宽度都较窄,一般只能容纳单个辆车通行,因而容易发生车辆在某区域内发生交通阻塞,会导致车辆频繁的倒车,造成了很多问题,更为严重的还会导致某些安全事故的发生。为了解决这些问题,设计研究煤矿胶轮车自动调度监控系统是非常必要的。
根据煤矿巷道的实际设计,矿井的实际建筑结构分成两类,即直线型巷道和三岔口型巷道,针对这两种结构分别进行分析研究,在参考大量煤矿胶轮车调度监控系统及相关信集闭算法设计的基础上,设计了两种结构相对应的基站布置与控制策略。
煤矿胶轮车自动调度监控系统由煤矿地面与井下两部分构成。地面部分主要是工控机,主要功能是对井下实际工作状况进行实时监测,调度控制、报警等。井下部分主要是由基站单元构成,功能是无线检测系统采集实时信息,基站通过处理运算,把行车的车号、位置、行驶方向,通过总线传递给地面的工控机,因此上位监控主机的核心任务是通过得到的下位机信息判断查找对应的控制策略,把控制命令通过总线传递给相应基站,并将整个调度过程实时形象的显示在工控机上。
控制思想与策略通过实验得到了验证,通过实际的运行实验,表明系统可以满足实时的自动控制与调度目的,并证明该设计符合系统的设计要求。

论文外文摘要: |
There are two modes of transportation, one is the main transportation, and the other is the auxiliary transportation, which is divided into rail auxiliary transportation and non-rail auxiliary transportation. Auxiliary transportation is characterized by suspended single-track rail and the laying double rail ; trackless auxiliary transportation takes motor vehicles as the main feature, in which trackless tire vehicle is one of non-rail auxiliary transportation Currently, many new coal mines adopt this new mode of transportation, but due to the cost and underground coal mining work space, auxiliary transportation roadway is narrow, so it can only accommodate a single vehicle traffic generally, and is prone to lead to not only traffic congestion in a region but also frequent reversing of vehicles, causing many problems,. More seriously, it will cause some safety accidents. To solve these problems, the design of mine tire vehicle automatic control and supervision system is necessary.
According to the actual design of coal mine tunnel, the actual building structure of mine is divided into two categories that is linear type of tunnel roadway and divergence. These two structures were studied, based on reading a large number of documents of coal rubber tire vehicle control and supervision system and signal centralized and locking system, the base station layout and control strategy corresponding to the two structures is designed.
Mine tire vehicle automatic control and supervision system consists of the surface part and underground part. The ground segment is mainly industrial computer, and the main function is th real-time monitoring, scheduling control, alarm of actual working conditions underground. The underground segment’s function is real-time information collection by wireless detection system, the base station passes the vehicle's license plate number, location and driving direction to the PC by bus. Thus, the main task of the host computer is to get the crew information, determine the corresponding control strategy, deliver control commands to the appropriate base station via the bus, and display the real-time image of entire scheduling process in the host computer.
The thought of control and strategies have been verified by experiment. The actual experiments shows that the system can meet the real purpose of the automatic control and scheduling, and prove that the design meets the design requirements of the system.
