Abstract

The work presented in this paper is useful to any application involving a trolley-powered vehicle; however, it is of interest, in particular, to trolley-powered haul trucks operated at open pit mining sites. The paper presents a designed and developed prototype for an automatic guidance system for an overhead electric-powered truck. The main purpose of the automatic guidance system is to maintain the truck inline under the overhead power lines, allowing it to achieve higher speeds on grade. In an open pit mine with a trolley operation, this would be an added feature to the direct trolley and diesel boost application. The automatic guidance system would assist or completely relieve the driver when the truck is running on trolley, and hence, full utilization of the overhead trolley system would be achieved. The microcontroller-based guidance system measures simple quantities directly from the overhead power lines, and sends commands to guide the vehicle without the need for tracks or buried wires. The system is tested and validated on a model truck powered by overhead lines, which is designed and built to emulate the real haul truck of mining sites.

矿用手推车自动导向系统

本文提出的工作对任何涉及有轨电车的应用都是有用的;但是，对在露天采矿场址上使用的以电车为动力的运输卡车特别感兴趣。本文介绍了一种架空电动卡车自动导航系统的设计和研制样机。自动导向系统的主要目的是保持卡车在架空电线下的直线，使其在坡度上达到更高的速度。在使用台车作业的露天矿中，这将是直接台车和柴油增压应用的附加功能。自动引导系统在货车在小车上行驶时，对驾驶员起到辅助或完全解除的作用，实现了高架小车系统的充分利用。基于微控制器的引导系统直接从架空电线测量简单的数量，并发送命令来引导车辆，而不需要轨道或埋线。该系统在一辆由架空线路供电的模型卡车上进行了测试和验证，该模型卡车是为了模拟采矿现场的真实运输卡车而设计和制造的。
