Measurement System Development for On-Line Test of Electric Vehicle

초록

Recently, TTX has been trial running on Chung-buk commercial line after accomplishing the factory test. The total measurement system (hereafter DAQ-Data Acquisition system) has been operated to estimate performance of train. The DAQ system developed by domestic technology is the most progressed system among the others. One of the main characteristic of the system is the TMS signal, the network input signal of train. It is able to make more accurate test evaluation and effective hitch diagnosis since the network signal can be analyzed and compared with the other signals acquiring from various sensors and controllers. The system is designed to inspect the TMS network line. It measures the train control signal in real time and saves the data. In this paper, a measurement system, which is time synchronized with the DAQ system and evaluates the various signal from controllers, sensors and each equipment, is studied. The reliability and safety of TTX has been improved by this measurement system.
