In this project, we make research in the measurement of the power-net which plays an important role in the electrization railway system. Applying the theory of CCD and CCD devices, we design a set of optics system, and using the MCS-51 as the controlling kernel. To transmit and store the data, we utilize the technique of IrAD and serial transmission.

摘要本论文首先探讨了当前电气化铁路接触网测量方面的问题，并针对这些问题研究了CCD理论及CCD器件在光电检测中的应用，同时根据该理论设计出一套光学系统，并以在智能检测领域中应用很广的MCS-51微控制器为控制核心，运用红外及串行传输技术，实现了数据的检测及存储。

It is suitable for the pipeline of Electrization railway Touch Net, large thermoelectricity station, petroleum, chemistry, metallurgy and so on, helping them to eliminate temperature response strength, letdown vibration and keep balance of strength.
