A rail traffic signal monitoring system

Abstract

The invention belongs to the technical field of rail traffic signals, and relates to a rail traffic signal monitoring system; it includes three server levels and a terminal equipment level, and the three server levels are respectively a central level server, a station level server and an equipment level server; the terminal equipment level Including the ground and on-board equipment in the rail transit signaling system; high-speed network communication (wired or wireless) is used between servers, servers and terminal equipment. The center-level and station-level servers use general-purpose desktop relational databases, and the device-level servers use relational databases suitable for embedded systems. The three-level servers monitor all terminal devices within the scope of this level and provide corresponding levels of management and maintenance methods. The new track traffic signal monitoring system involved in the present invention is an important system to ensure driving safety, strengthen signal equipment management, and monitor signal equipment, and is also an indispensable and important means to realize signal system maintenance, which can meet the needs of various types of railway and track traffic signal monitoring .

Description

technical field [0001] The invention belongs to the technical field of rail traffic signals, and in particular relates to a rail traffic signal monitoring system. Background technique [0002] The rail transit signal monitoring system is to ensure traffic safety, strengthen the management of signal equipment joints, monitor the status of signal equipment, discover hidden dangers of signal equipment, analyze the cause of signal equipment failure, assist in troubleshooting, guide on-site maintenance, reflect the quality of equipment use, and improve the quality of electrical services. The maintenance level and maintenance efficiency of important driving equipment should be planned and implemented in a unified manner, and the design, construction, commissioning, acceptance and opening of interlocking, blocking, train control, TDCS / CTC, hump and other systems should be synchronized. [0003] Existing traditional rail transit signal monitoring system (see figure 2 ) is composed ...

AI Technical Summary

Problems solved by technology

However, with the explosive development of the rail transit industry, the traditional rail transit signal monitoring system has exposed many shortcomings. Occurs resulting in the loss of terminal device-level monitoring information

The loss of monitoring information makes the monitoring information incomplete, which affects the on-site playback and fault analysis and positioning after the fault, and ultimately reduces the availability and maintainability of the entire signal system; secondly, the terminal equipment in the traditional rail transit signal monitoring system is directly connected to the The station-level server and the terminal level cannot provide the signal system monitoring and maintenance interface. During system deployment or maintenance, technicians need to use the monitoring and maintenance interface of the station-level server or central-level server to analyze and process the current status and historical faults of the terminal equipment. The efficiency of deployment and maintenance has had a considerable impact
