Train collision prevention warning system

Abstract

The invention relates to a train collision prevention warning system. A train information collection module is used for collecting train status information, and the train status information comprises a train running line, a train location, a train speed, a safety level and the like; a wireless communication module is used for wirelessly broadcasting the train status information and wirelessly receiving the train status information broadcast by other trains; and a CPU (central processing unit) control processing module is used for receiving and processing the train status information of the train and other trains collected by the train information collection module and transmitted by the wireless communication module. The current train status information of the train can be broadcast wirelessly to other trains via the wireless communication module, the train status information wirelessly broadcast by other trains can be received by the wireless communication module, the running safety distance and speed can be judged by the CPU control processing module according to relationships between the train and other trains, and pre-warning signals can be sent to drivers and automatic train operation systems. The system has a simple and reliable structure and can be installed conveniently, the train drivers can promptly know running statuses of approaching trains, and the train running safety can be improved effectively.

Description

technical field [0001] The invention relates to a train running automatic control system of rail transit, in particular to a train anti-collision warning system during train running. Background technique [0002] Modern automatic train operation control system (ATC) includes subsystems such as automatic train protection (ATP), automatic train operation (ATO) and automatic train monitoring (ATS). Among them, the function of the ATP subsystem is to protect the train from overspeed, realize the position detection of the train, ensure the safe interval between the trains, ensure the train runs at a safe speed, and complete the signal display, fault alarm, degraded prompt, train parameters and line parameters input etc. The ATC system needs to set up a traffic control center, set up chain control stations along the line, and install on-board control equipment on the train. The control center and the control station are connected through a wired data communication network, and t...

AI Technical Summary

Problems solved by technology

[0003] When the ATC system fails due to factors such as environmental interference, human error, or equipment defects, it is impossible to completely avoid the possibility of trains colliding with each other.

The current train on-board control equipment can only rely on signals provided by ground facilities such as track circuits, ground transponders, trackside cables, and ground wireless communication base stations to obtain information about the current line, and cannot directly obtain information such as the position and speed of other nearby trains.

Once these ground train operation control equipment fails or there is a traffic scheduling error, the trains that are close to each other cannot obtain the status of each other in a timely and effective manner, and the train driver cannot guarantee the safe distance between the trains, which may lead to vicious train collisions.
