Train control method and system and vehicle on-board controller (VOBC)

Abstract

The invention discloses a train control method and system and a vehicle on-board controller (VOBC). The train control method comprises the steps of enabling an automatic train protection system (ATP)operating in the VOBC to transmit train running state information to an automatic train operation system (ATO) operating in the VOBC; receiving train control information transmitted by the ATO, wherein the train control information is calculated by the ATO according to the train running state information; and transmitting the train control information to a train so that the train runs according tothe train control information. According to the train control method and system and the VOBC, the on-board ATP and the ATO can be combined into one set of hardware equipment to run to reduce hardwareresources occupied by the ATP and the ATO; and moreover, the ATP and the ATO are connected with a vehicle through the same vehicle interface to reduce vehicle interfaces; and through adoption of a communication interface between the ATP and the ATO, the hardware wiring complexity and project cost are greatly reduced.

Description

technical field [0001] The present application relates to the technical field of train control, in particular to a train control method, system and on-board controller. Background technique [0002] In the existing related technology, the on-board protection and driving system are two independent on-board subsystems, namely Automatic Train Protection System (hereinafter referred to as: ATP) and train automatic driving system (Automatic Train Operation System; hereinafter referred to as : ATO), respectively run on two sets of devices with the same hardware. The vehicle-mounted ATP is responsible for reporting its own position to the ground in real time, and protecting elements such as distance, speed and vehicle door according to the received mobile authorization information; the vehicle-mounted ATO realizes the automatic driving and automatic control of the vehicle. ATP and ATO are respectively connected with the vehicle interface to realize the safety protection and automa...

AI Technical Summary

Problems solved by technology

[0003] However, in the existing related technologies, ATP and ATO need to monopolize the hardware resources of a set of equipment respectively, resulting in high hardware costs. In addition, ATP and ATO need to be independently connected to the vehicle interface, and it is necessary to distinguish between safe interfaces and non-safe interfaces. ATP There is also a need for a communication interface with the ATO, resulting in more interfaces between the on-board equipment and the vehicle, and the complexity of hardware wiring and high project costs
