Railway unattended crossing monitoring method and device

Abstract

The invention belongs to an automation control technology, and particularly relates to a railway unattended crossing monitoring method and a railway unattended crossing monitoring device. The railway unattended crossing monitoring device comprises a controller, an electric guardrail, a prompting device and train information collecting devices, wherein the train information collection devices consist of several groups of sensors and information transceivers and are respectively arranged at the two sides of a railway crossing, the prompting device comprises a traffic lamp and a warning device, and the controller is respectively connected with the information transceivers, the electric guardrail, the traffic lamp and the warning device. The method and the device provided by the invention have the beneficial effects that the unattended automatic control on the railway crossing is realized, errors possibly occurring through personnel operation are avoided, the safety of the railway crossing can be effectively improved, meanwhile, the realization mode is simple, and the cost is low. The railway unattended crossing monitoring method and the railway unattended crossing monitoring device are particularly suitable for being used at the railway unattended crossing.

Description

technical field [0001] The invention belongs to the automation control technology, and in particular relates to a monitoring method and device for railway unmanned crossings. Background technique [0002] At present, the equipment used for railway crossing protection is DX3 type crossing signal equipment. Its working principle is: when there is no train approaching the crossing, the notification relay of the equipment's approaching notification point will be sucked up, so that the alarm relay will keep sucking up through the self-closing contact. When the train arrives at the approach notification point of the crossing, the notification relay will drop, so that the excitation circuit of the alarm relay will be cut off, so that the alarm relay will drop, and the alarm circuit will be connected. At this time, an alarm signal will be given, and the direction relay will start Self-closing, light up the direction indicator light, when the train enters the crossing and reaches the...

AI Technical Summary

Problems solved by technology

[0007] Among them, the X3 type crossing signal equipment can only automatically control the traffic light of the crossing signal machine to turn on and off, and cannot realize the automatic control of the crossing fence and voice broadcast prompts, so the equipment needs to be guarded by crossing guards; the railway based on DSP and Ethernet The cost of the crossing monitoring system is high and the reliability and stability of the Ethernet is poor; the crossing image monitoring system can only enable the train driver to understand the situation of the crossing ahead but cannot realize the automatic control of the crossing fence and signal machine. In addition, the system The real-time and stability are not good; the GPRS wireless communication network used by the ARM control system based on GPS and GPRS has GPRS network blind spots in remote areas, and the real-time communication between trains and crossing equipment cannot be guaranteed, so it has certain limitations ;The above schemes are for single crossing control, without uploading crossing data to the monitoring center in time, it is impossible to realize global monitoring of crossing status

Therefore present railway crossing does not have a kind of reliable automatic control system
