摘 要
运料小车在煤矿、仓库、港口车站、矿井等行业中被广泛应用，而其控制系统就是一种典型的PLC系统。传统的运料小车大多是继电器控制，而继电器控制有着接线复杂、易出故障、维护维修不易等缺点。为了降低运料小车的运行成本,实现自动化控制，应用可编程控制技术作为小车的控制系统。
本设计针对电气控制的运料小车系统，利用组态软件和西门子S7200 PLC实现对运料小车系统的监测和控制。通过现场数据采集，进行集中的数据管理，从而实现对自动运料小车系统有效控制，系统状态实时监控，并由上位机生成可视化的动态监控界面。方便管理人员对现场的管理，提高工作效率。

Abstract
Abstract
Carriage is widely used in coal mine, warehouse, station, port mine and other industries, and its control system is a typical PLC system. The transport cars most of the traditional relay control, relay control with complex wiring, easy maintenance, fault repair defect is not easy. In order to reduce the operation cost of material transport trolley, automatic control system, the application of programmable control technology as the control system of car.
The design for the carriage of electric control system, realize the monitoring and control of material transport trolley system using configuration software and S7200 PLC Siemens.Through the field data acquisition, data management, so as to realize the automatic control of material transport trolley system, real-time monitoring system status, and made the dynamic monitoring interface PC to generate visual. Management to facilitate the management of the site, improve work efficiency.
Keywords: Material transport trolley;configuration software; PLC; sensor;
