The contact and messenger wire is important parts in the electric power system of the railroad. There are so many measurement method like voltage, current, scratch of surface, and glow longer of length. In this paper suggest real time monitering system of messenger wire so called RTU (Remote Terminal Unit) and this system includes CDMA module to transfer real time or saved data of memory to the end user directly who is in the long distance. The hyper terminal program of windows shows the downloaded data from RTU through CDMA communication and this data can be transferred to excel sheet easily.

This study deals with the problem of balance beam system to stabilize about static and sinusoidal disturbance. wherein the design objectives are to keep the gap deviation from static and sinusoidal disturbance. In this paper propose the 2-Degree of Freedom(DOF) structure and a simple first-order controller which is designed by Characteristic ratio assignment (CRA) method. Matlab simulation result verify stabilization of balance beam system despite of disturbance. Hybrid simulation between digital controller and analog plant is presented by Matlab Simulink.
