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.
