Design of a Monitoring Unit for Railway Trackside Signal Equipment

Abstract

Aiming at the function and environmental requirements of monitoring railway trackside signal equipment, a general monitoring unit providing rich data acquisition interface, powerful digital processing ability and reliable communication transmission function is designed, which is available for monitoring most of railway trackside equipment. Based on the unit, a device to monitor the trackside equipment of track circuit system, which possesses the largest number, the widest distribution and the most complex application environment, is realized in this paper.
