摘 要
随着工业控制过程中控制要求的不断提高，系统的性能也在不断的进行完善。现今，工业控制系统的设计不仅注重其实用性，更加趋向于向着安全性、可靠性、直观性而发展。本文对于焦炉电机车控制系统的设计，采用了以变频器连接电源、电机，构成焦炉电机车的拖动系统，实现其基本的控制功能，避免了以往其复杂的运行及调速、复位等环节。对于电机车的操作系统，设计了与电机车相对应的触摸屏来实现人机交流，使其操作更加的灵活、安全、可靠、直观。
本文首先介绍了焦炉电机车的基本组成及工作原理，然后介绍了在本次设计中变频器的选择，并阐述了如何按照设计思想应用变频器对电机车进行连接与控制，最后详细的阐述了本设计中的整个拖动系统是如何通过操作系统来实现控制的。

The Coke Oven Electric Locomotive Control System Design
Abstract
With the unceasing enhancement of control requests in industry controlled process, the system performance has also been improved. Nowadays, not only the industry control system design pays great attention to its use, even more tends to the development of the security, the reliability, the intuition. Regarding the coke oven electric locomotive control system design, this article has used the converter to connect the power source and the electrical machinery, constituted the coke oven electric locomotive control system, realized its basic control function, has avoided formerly complex links of movement and velocity modulation replacement. Regarding the electric locomotive operating system, this article has designed the touch screen which corresponds with the electric locomotive to realize the man-machine exchange; even more caused its operation to be nimble, to be safe, to be reliable, to be direct-viewing.
This article has first introduced the coke oven electric locomotive''s basic composition and the principle of work, then introduced the choice of the converter in this design, and elaborated how to use the design concept to carry on the connection and the control for the electric locomotive by the converter, finally, it has detailed elaborated how the driven system is realized through the operating system in this design.
Key words：coke oven electric locomotive, converter, touch screen
