At first, based on the theory of System Engineering, through analysis, this system can be divided to four subsystems: locating tramcar, loading mine controlling, dispatching conducting and mining calculating, thus a general program of the system was worked out.

首先，应用系统工程的方法，对本系统进行分析，把本系统分解为矿车对位、装矿控制、调度指挥和出矿计量四个子系统，确定了系统的总体方案。

The transmission technology of direct current of alternating transmission technical replacement tradition becomes the tendency of present tramcar power pull. It is imported abroad because of the city vehicle alternating transmission systematic most dependences of our country.

交流传动技术取代传统的直流传动技术已成为目前现代有轨电车电力牵引的趋势,由于我国的城市轨道车辆交流传动系统大多数依赖国外进口,因而城市轨道车辆交流传动系统中牵引逆变器的国产化则是目前的重点研究课题。
