Railway crossing remote centralized control and intelligent early warning integrated system

Abstract

The invention discloses a railway crossing remote centralized control and intelligent early warning integrated system. The system comprises a dispatching center control subsystem, a dispatching center video/audio subsystem, a crossing field front-end device subsystem and an optical fiber communication subsystem. The dispatching center video/audio subsystem is connected with the dispatching center control subsystem. The crossing field front-end device subsystem is connected with the dispatching center control subsystem through the optical fiber communication subsystem. The dispatching center control subsystem comprises a control server and a communication controller, achieves monitoring and control over all devices of the other three subsystems and completes remote control command for dispatching operators. The dispatching center video/audio subsystem comprises a video image display module and a video/audio storage device matrix. Remote videos, remotes audios and remote control are centralized and integrated into the system, the efficiency is improved, the operation is facilitated, and the system is safer and more reliable.

Description

technical field [0001] The invention relates to the technical fields of remote control of railway crossings and auxiliary coal transportation, in particular to an integrated system of remote centralized control and intelligent early warning of railway crossings. Background technique [0002] Existing railway level crossing management technology mainly adopts manual management of important crossings or simple automatic alarm control mode. In the 1990s, the automatic crossing alarm and automatic pole drop technology based on the control of industrial controllers appeared. The principle is that the rails at a certain distance (according to the speed of the vehicle, about 1 km) on both sides of the crossing are equipped with "crossing proximity sensors" and "arrival sensors" are installed on the crossings. , when the train approaches the crossing, the proximity sensor is triggered, and the sound and light alarm device is automatically turned on at the crossing, and the fence m...

AI Technical Summary

Problems solved by technology

However, this method does not carry out safety control on the most important railing machine for crossing safety protection, and it is easy for motor vehicles to collide with the railing.

This problem has not been effectively resolved

Low safety and reliability, high cost, no unified management

[0005] 2. The vast majority of crossing management only adds crossing monitoring video, and the video is stored in the crossing room, which is only used for accident analysis

[0006] 3. Most video systems also use analog to ensure the best real-time performance, while those using IP network high-definition also ignore the real-time problem and only pursue high-definition

As for the high-definition and high-real-time SDI method, it is not adopted due to the price
