Rail transit comprehensive monitoring system based on integration mode

Abstract

The invention discloses a rail transit comprehensive monitoring system based on an integration mode. The rail transit comprehensive monitoring system comprises a comprehensive monitoring system layer and a rail-station accessing system layer. The comprehensive monitoring system layer includes a plurality of subsystems, and equipment of each subsystem is directly connected to a rail-station-level local area network of the comprehensive monitoring system. The rail-station accessing system layer is provided with a plurality of rail-station field apparatuses, and each rail-station field apparatus is connected with the corresponding system through a rigid line. By the aid of the rail transit comprehensive monitoring system, the upper and lower computer structures of an existing discrete monitoring system can be integrated, functions of the existing discrete monitoring system can be completed on a hardware platform of the comprehensive monitoring system uniformly, so that network resources can be better utilized, software functions are optimized, and program constructing processes are simplified.

Description

technical field [0001] The invention relates to a rail transit comprehensive monitoring system, in particular to a rail transit comprehensive monitoring system based on an integrated mode. Background technique [0002] The essence of the comprehensive monitoring system adopted by the current rail transit comprehensive monitoring system is to split the upper and lower computer structures of each subsystem in the early discrete monitoring mode into two independent parts for design, implementation and debugging. One of its major features is that the original discrete integrated subsystems are cut into two parts at each site. The monitoring part of the upper computer is completed by the integrated monitoring system, and the part of the lower controller is completed by the integrated subsystems. The integrated monitoring system based on this structure usually sets up special gateway structural equipment to realize data communication and information isolation with each access syst...

AI Technical Summary

Problems solved by technology

[0003] (1) The utilization rate of network resources is low, which not only causes waste of existing resources, but also sacrifices some of the original auxiliary functions of the subsystem, and also increases the overall investment cost of the project

[0004] (2) From the perspective of software data collection and processing, a conversion and reprocessing link is added in the entire data processing process, which directly leads to a drag on the real-time responsiveness of the system

[0005] (3) From the point of view of the project implementation process, due to too many layers, multiple interfaces are cumbersome and the interface coordination is too large, the debugging workload of each system is huge, the number of joint debugging increases, and fault diagnosis and system maintenance are also extremely inconvenient
