Problems solved by technology
When the train is running at CTCS-3 level, due to GSM-R wireless communication failure, RBC (Radio Block Center, radio block center) failure, train control system failure and other reasons, the communication session between the train and RBC may be interrupted, so it cannot be normal Operates at CTCS-3 level
The relevant national regulations stipulate that in this case, in order to maximize the operating efficiency, the train should be automatically downgraded to CTCS-2 level operation. Trains operating at CTCS-3 level will be directly downgraded to CTCS-2 level operation, so the fault response mechanism is not flexible

Embodiment Construction
[0013] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0014] It should be understood that the embodiments according to the present invention can be applied to various trains, and can be applied to trains running on various speed-raising lines and passenger-dedicated lines, for example, CTCS multi-level trains. According to the embodiment of the present invention, the CTCS-3 level train control system is superimposed on the CTCS-2 level train control system as an example for illustration, but the embodiment...

The invention provides a method and a device for train automatic protection. The method includes that under the condition that over time of a wireless message of a train occurs, a reaction type directed at the over time of the wireless message is confirmed. The reaction type includes degraded running. When the reaction type is confirmed to be degraded running, the train is degraded to run from a first running grade to a second running grade. Under the condition that the over time of the wireless message of the train occurs, the train is not degraded to run from the first running grade to the second running grade until the reaction type is confirmed to be the degraded running, so that a flexible reaction mechanism for the over time of the wireless message is provided.
Description
technical field [0001] Embodiments of the present invention relate to the field of automatic control, and more specifically, relate to an automatic train protection (ATP, Automatic Train Protection) method and device. Background technique [0002] The train operation control system is an important technical equipment to ensure the safety of train operation and improve the efficiency of train operation. It is used to monitor the speed and interval of train operation to protect the operation of trains. At the same time, it can reduce the labor intensity of drivers and improve working conditions. And improve passenger comfort. [0003] According to the transportation requirements such as railway line conditions, train characteristics, and operating speed, CTCS (Chinese Train Control System, China Train Operation Control System) is divided into 5 levels. Among them, the 200-250km / h speed-up lines and passenger dedicated lines generally adopt CTCS-2 (Chinese Train Control System...
