Point train control system and its control method under cbtc fault mode

Abstract

The invention discloses a punctual train control system in a CBTC (Communication-based Train Control) fault mode and a control method of the punctual train control system in the CBTC fault mode. The punctual train control system comprises an ATS (Automatic Train Supervision) system, an axle counting system, an interlocking system, a trackside ATO (Automatic Train Operation) part, a trackside ATP (Automatic Train Protection) part, a trackside radio station, a vehicle-mounted radio station and a target controller, and particularly comprises a signal machine, a signal machine beacon, an advance announcing beacon and a vehicle-mounted ATC, wherein the ATS system is used for sensing various control commands; the axle counting system is used for monitoring the train positions; the interlocking system and the trackside ATO part are used for receiving the control commands from the ATS system; the trackside ATP part is used for building train moving authority; the trackside ratio station is used for sending the moving authority information of the trackside ATP part; the vehicle-mounted ration station is used for receiving information of the trackside ratio station; the target controller is used for collecting the trackside equipment state information; and the vehicle-mounted ATC comprises a database. The punctual train control system has the function of punctual ATC automatic driving, and also has the functions of double-red-lamp protection, overspeed protection, train precise station stop and the like at the same time.

Description

technical field [0001] The invention relates to the technical field of train automatic control, in particular to a point train control system and a control method thereof under a CBTC failure mode. Background technique [0002] Communication-based Train Control (CBTC, Communication-based Train Control) is a mobile block system at the forefront of signaling system technology. In the international standard IEEE1474.2, the characteristics of CBTC are described as "high-precision train positioning independent of track circuits, continuous and large-capacity two-way train-ground data communication, and an automatic train control that performs safety functions on-board and trackside." system". However, it is worth noting that since this technology uses two-way vehicle-to-ground communication, once the wireless network is interfered, or the regional controller or vehicle antenna fails, it will cause serious operational disruption. In addition, when vehicles without on-board equip...

AI Technical Summary

Problems solved by technology

Many failure points and high equipment costs

[0007] c) When the parameters of trains purchased in different batches change, it is necessary to shift the position of fixed and blocked boundaries (such as signal machines and axle counting points), and the cost of later transformation is very high

[0008] 3) Neither of the two schemes can achieve point-type ATC automatic driving, and the driver must drive the train purely manually or under the protection of ATP
