Unmanned on duty train barrier detection system

Abstract

The invention discloses an unmanned on duty train barrier detection system comprising platform equipment and vehicle equipment; the platform equipment is used for collecting video information on the head and tail of a railing zone platform with no safety door or a half-height safety door, detecting barriers according to object sizes in the video information, and sending alarms when a barrier is detected; the vehicle equipment is used for using a plurality of sensor switches to detect barriers in front of a train in a non-contact manner, and sending alarms when any sensor senses a barrier. The system allows the unmanned train to determine barriers in a low speed non-contact condition and in high risk zones like the platform, thus greatly improving the automation level and safety of the unmanned train signal system; in addition, the detection system is designed by using general relay or analog quantity interfaces, and can be directly connected into rail side or vehicle signal equipment.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to an obstacle detection system for unattended trains. Background technique [0002] With the development of urban rail transit and information technology, the unattended train driving system (FAO system) has become a new trend in the development of rail transit industry at home and abroad. To ensure the safe and efficient operation of trains, the FAO system has extremely high safety and reliability requirements. When unattended trains are running on the main line, it is necessary to ensure that the running line is clear and there are no obstacles that threaten driving safety on the way ahead, especially in the area within the half-height safety gate station area, it is necessary to protect people and objects from intruding into the track Happening. [0003] For the safe operation of the unattended train control system, most of the current methods are to install multiple sets...

AI Technical Summary

Problems solved by technology

[0009] 1) Cannot avoid collision without contact

[0010] Since the train collision detection is based on the post-collision detection, it is impossible to realize the early warning of pre-collision even in the depot and when the main line is running at low speed

[0011] 2) Multiple sensors need to be installed on the vehicle

[0014] Since infrared interfacing needs to arrange more points on both sides of the track area of ​​the platform, the wiring will increase the difficulty of construction, and in a high-vibration environment, it will cause misalignment of the interfacing device and cause false alarms

[0015] 4) Simultaneous inspection of vehicles and key platform areas cannot be achieved

[0016] The existing obstacle detection is either done by the vehicle or by the ground equipment. There is no synchronous detection of the vehicle and the ground equipment.
