Problems solved by technology

However, the obvious disadvantage of the track circuit is that the track circuit can only achieve one-way transmission from the ground to the vehicle, but cannot achieve two-way transmission
Moreover, the track circuit can only use a lower frequency to send information, ...

Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0032] The communication-based rail transit train automatic monitoring system of the present invention gets rid of the shackles of judging train occupancy and information transmission with ground track circuit equipment, and adopts Commercial Off-The-Shelf (COTS) technology to realize mobile blocking. The two-way communication between the train and the ground is carried out in real time or regularly, and the following trains can keep abreast of the running conditions of the train ahead. In order to realize the mobile block system, there is no need to pre-set fixed block partitions, but to calculate the safety distance between adjacent trains in real time and dynamically according t...

Abstract

The invention discloses a rail transportation train automatic monitoring system based on communication, which comprises on-board equipment and a ground automatic monitoring system. The on-board equipment arranged on the train is used for collecting train information and sending to the ground automatic monitoring system through a wireless network, and is also used for receiving and executing dispatching commands sent by the ground automatic monitoring system. The ground automatic monitoring system is used for receiving the train information from the on-board equipment, interlocking calculating according to the train information to generate dispatching commands and sending the commands to the on-board equipment through the wireless network. The invention realizes the closed loop control to the train through the train-ground bidirectional information transmission, greatly lowers the effect of human error, and raises the system reliability; ATS system real-timely knows various operation parameters of the train such as the position, the speed, etc. thereby improving the operation efficiency and the automation of the system; moving block is realized through wireless communication, thereby facilitating the improvement of traffic density; and the train can timely respond the dispatching and the adjusting commands of the ATS system.

Description

technical field [0001] The invention relates to the technical field of rail traffic control, in particular to a communication-based rail traffic train automatic monitoring system. Background technique [0002] Rail transit is an effective means to solve traffic congestion in modern cities. Its biggest features are high operating density, short intervals between trains, safety and punctuality. In recent years, the urban population has expanded rapidly, which has put forward higher and higher requirements for the passenger capacity of urban rail transit. In order to improve the passenger capacity, one of the measures is to increase the number of vehicles per train and increase the space capacity of the vehicles; the second measure is to shorten the interval between trains, thereby improving the passing capacity of the line. [0003] The existing train control system mainly uses the track circuit to transmit the information from the ground to the train. The track circuit has ...
