Abstract Maintenance and monitoring is the monitoring technology based on the development of testing and the computer technologies. The development of microcomputer supervision system is advantageous to tracking down the causes of breakdowns, shortening the time for removing obstacles, heightening train traffic efficiency. The Maintenance and Monitoring System (MMS) applies computers and information collection equipments to the real-time supervision of various signal equipments, providing the Communication Signaling Department with scientific basis for the control of the current states the equipments and the analysis of the error through monitoring and recording signal equipments’ functioning. It is composed of station supervision system, workshop computer, the signal department management system, up-layer network terminal (bureaus and MOR) and WAN data transmission system. The design of the station as a virtual station-Damo station in the ascending pharyngeal, design a signal layout, the figure can correctly reflect the electric centralized outdoor main equipment arrangement. Combination of connected graph and list, drawing combination connected graph, the use of the unique combination of frame alignment method to prepare a combined list row. Also on the-maintenance and monitoring objects in track circuit, switch and interval signal are studied. In order to adapt to the new requirement of equipment, using a
