Embodiment 1

[0060] A safe and fast unlocking method for continuation of the protection approach, including the calculation and judgment step of the vehicle controller, the analysis and processing step of the regional controller and the unlocking step of the interlocking system, such as Figure 1-3 as shown, Figure 1-3 Among them, CC represents the on-board controller, ZC represents the zone controller, and CI represents the interlocking system. In this embodiment, the parking information is specifically represented by the text "guarantee not to cross the parking restriction point", and its state information includes the allowed state and the restricted state; the permission to continue the unlocking of the protection approach is specifically represented by the text "allow overlap unlocking", and its state Information includes allowed and forbidden status.

[0061] 1. On-board controller CC calculation and judgment

[0062] The calculation and judgment step of the on-board controller is...

Embodiment 2

[0070] On the basis of Embodiment 1, this embodiment further elaborates on the calculation and judgment steps of the on-board controller. In the calculation and judgment step of the on-board controller, the on-board controller is Braking performance, train position, line conditions, train positioning and speed measurement and distance measurement error information, calculate the precise stopping point of the train in real time, and judge whether the train can stop safely and accurately at the designated stopping point according to the precise stopping point of the train calculated in real time.

[0071] (1) If the judgment result is that the train can stop safely and accurately at the designated parking point, set the state of "guarantee not to cross the parking limit point" as the allowed state, and send it to the regional controller.

[0072] (2) If the judgment result is that the train cannot stop safely and accurately at the designated parking point, set the state of "guara...

Embodiment 3

[0074] In this embodiment, on the basis of Embodiment 2, the regional controller analysis processing steps are further elaborated. "Information is analyzed and processed:

[0075] (1) If the information "Ensure not to cross the parking restriction point" is in the allowed state, and the train has already occupied the continuous protection route unlocking trigger section, then set the "allow overlap unlock" information sent to the interlocking system to the allowed state;

[0076] (2) If the information "guaranteed not to cross the parking restriction point" is in the restricted state, then set the "allow overlap unlock" information sent to the interlock system to the prohibited state.

Abstract

The invention discloses a safe and rapid unlocking method for a continuous protection route, and relates to the technical field of route control in a rail traffic control system.The method comprises the steps that whether a train can be accurately and stably parked at a designated parking point or not is calculated in real time through a vehicle-mounted controller, information is sent to an area controller, and the area controller confirms unlocking allowing state information; the unlocking permission state information is sent to the interlocking system, and the interlocking system adopts different delay strategies according to the time of receiving the unlocking permission state information to unlock the continuous protection route; the vehicle-mounted controller actively calculates the accurate parking point of the train in real time, after it is determined that the train can be accurately and stably parked at the designated parking point, the interlocking system can immediately unlock the continuous protection route, it is not needed to initiate a continuous protection route unlocking request to the area controller, the continuous protection route unlocking efficiency is improved, and the safety of the train is improved. The train stopping time can be effectively shortened.

Description

technical field [0001] The invention relates to the technical field of route control in a rail transit control system, and more specifically relates to a method for safely and quickly unlocking a continuation protection route. Background technique [0002] The communication-based train operation control system (Communication Base Train Control, CBTC), through the train-ground two-way wireless communication and the ground wired communication, can obtain information such as the train position, running direction, train speed, etc. in real time, and send the movement authorization terminal point to the controlled train Information (End of Movement Authority, EOA). [0003] In order to meet the requirements of parking safety and parking accuracy, and prevent trains from rushing forward due to line conditions, insufficient braking performance, or misoperation, leading to traffic accidents, a continuous protective approach is often added outside the approach. The continuation of t...
