Method and device for generating train movement authorization, on-board atp and zc

Abstract

The invention proposes a method and device for generating a movement authorization of a train, an ATP and a ZC. Among them, the method includes: obtaining the first distance between the preceding vehicle and the following vehicle, obtaining the reaction time required for the following vehicle to run the first distance according to the speed information of the following vehicle, and obtaining the distance of the preceding vehicle according to the speed information of the preceding vehicle. The second distance traveled within the reaction time generates a movement authorization for the following vehicle according to the first distance, the second distance and a preset safety margin. In the present invention, when calculating the movement authorization of the rear vehicle, the actual motion state of the vehicle in front is considered, and the vehicle in front is no longer set as a static obstacle, which can make the movement authorization longer, thereby reducing the tracking distance and improving the accuracy of the route. Operational efficiency can increase the departure density during the peak period of operation and reduce the operating pressure during the peak period.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a method and device for generating a train movement authorization, a vehicle-mounted ATP and a ZC. Background technique [0002] Currently, all trains registered to the Zone Controller (ZC for short) can report their real-time location information to the ZC. ZC can calculate the movement authorization of the following train based on the position information reported by the preceding train. When the front ZC calculates the movement authorization of the following vehicle, it calculates based on the absolute position of the train. In the process of calculating the movement authorization, ZC assumes that the vehicle in front is a stationary obstacle. When it is assumed that the front vehicle is a stationary obstacle, the position of the front vehicle becomes a fixed position, and the position relative to the position of the rear vehicle is an absolute position, so that the absolut...

Problems solved by technology

In order to ensure the safe operation of the train, the minimum tracking interval of the front and rear vehicles cannot exceed the emergency braking distance of the rear vehicle, otherwise the emergency braking will be triggered, which makes it impossible to determine the distance according to the actual operating conditions during the peak period of train operation. Abbreviated track intervals between trains, making the line less efficient to operate
