Railway crossing safety protection early warning system

Abstract

The invention relates to a railway crossing safety protection early warning system. The railway crossing safety protection early warning system is characterized by consisting of a monitoring center subsystem, a track maintenance division subsystem, a site subsystem and a network which is connected with each subsystem, wherein the monitor center subsystem acquires the state and an operating plan of a signal device through a TDCS interface server and consists of a crossing safety protection module, a crossing management module and an emergency communication module; the track maintenance division subsystem acquires the real-time information of a crossing from the monitoring center subsystem and monitors the administered crossing in real time, and the track maintenance division subsystem consists of an external interface module, a crossing safety protection module, an identification module and an emergency communication module. By adopting the railway crossing safety protection early warning system, the precision, reliability, comprehensiveness and economical performance for locating a train can be improved, stable and reliable communication connection between a center and a site can be established, an alarming target not only contains motor vehicles and pedestrians, but also contains a train driver, the safety risk of the crossing can be maximally reduced, a closed-loop cooperative network is formed by relevant elements, and the poor interaction problem of the information in the safety management of the crossing can be fundamentally solved.

Description

[0001] Field [0002] The invention discloses an early warning system for railway crossing safety protection. The system is based on systems and technologies such as TDCS, wireless train dispatching, GSM-R and Beidou satellite navigation, and consists of three parts: the central subsystem, the engineering section subsystem and the on-site subsystem. The invention manages the safety elements related to the crossing through the network, and fundamentally improves the safety protection level of the crossing. Background technique [0003] Crossing refers to the level intersection of road and railway, where the width of the pavement is 2.5 meters or more, and the level intersection directly runs through the road. A crossing is a passage for trains, motor vehicles, power storage vehicles, pedestrians and livestock, and its management involves multiple departments such as railways, security checks, public security, and urban construction. Crossings have always been a weak link in r...

AI Technical Summary

Problems solved by technology

[0006] For unguarded crossings, due to the lack of effective dynamic warning signs, it mainly depends on the subjective safety awareness of motor vehicle drivers and pedestrians, and the traffic safety at crossings cannot be guaranteed

[0007] For guarded crossings, its safety depends more on the work responsibility of the guards, and the management department cannot monitor the working status of the on-site staff in time

In addition, the watchman only knows the approximate location of the train, but cannot know the speed and arrival time of the train; the crossing lacks a dynamic display early warning system for motor vehicle drivers and pedestrians; the crossing cannot monitor motor vehicles and pedestrians in real time, and cannot effectively curb violations

All of these have posed hidden dangers to the safety of the crossing.

[0008] For automatic alarms installed at some crossings, it is necessary to install train detection equipment at a certain distance from both ends of the crossing, and wire from both ends to the center, which is difficult to implement and costs a lot.

In addition, since many crossings are located in remote areas, there are many difficulties in obtaining power for equipment and maintaining the system

[0009] A railway crossing multimedia information sharing and interaction device disclosed in the comparative document 1CN202911753U only solves the current problem of sharing information resources at crossings. In the early warning process, manual on-site observation or remote video monitoring cannot automatically identify the position of the train, let alone realize it. Automatic warning
