Abstract: Most equipment of signaling systems is featured with a redundant structure. Single-UPS becomes the problem on increasing the reliability of signaling systems. Therefore, the paper puts forward a new scheme by using dual-UPS to improve the reliability of signaling systems and then enhance the quality of signal systems and train operation.
