Embodiment Construction

[0035] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0036] figure 1 It shows that Embodiment 1 of the present invention provides a method for unlocking the route protection section, including:

[0037] S11. Acquiring a confirmation signal that the train enters a stationary section, and the stationary section is a section before the train enters an approach protection section.

[0038] In this step, it should be noted that a route protection section is set on the train route of the station. It is set as the last section of the train entering the road on the section before the train entering the road. The train needs to come to a complete stop in this last area, so it can be ordered as the stop section before the train ent...

Abstract

The invention provides a device and a method for unlocking a route protection section. The method includes: acquiring a confirmation signal of a train driven into a standstill section which is a section before the route protection section; acquiring a standstill signal of the train in the standstill section; obtaining standstill elapsed time of the train according to the confirmation signal and the standstill signal; if the elapsed time does not exceeds preset time, unlocking the route protection section. Therefore, unlocking time of the route protection section is shortened, train operating intervals can be shortened, and operating efficiency of the train is improved. In addition, the method is also applicable to CBTC (communication-based train control) and punctual control systems, and operating efficiency of the train under control of the punctual control system is improved.

Description

technical field [0001] The invention relates to the technical field of rail traffic control, in particular to an unlocking method and device for an approach protection section. Background technique [0002] With the rapid development of communication technology and urban rail transit, communication-based train control system (CBTC system) has become the direction of modern transportation technology research and development, which improves the automation level of train control and reduces the running interval of trains. [0003] In order to ensure the safe operation of the train and avoid accidents caused by the train not being able to stop at the signal machine for some reason, factors such as the braking distance and the line of the train are fully considered, and a protection zone is set after the stop point, that is, the terminal One or two sections behind the signal are protected sections. When the train stop is close to the terminal signal, provide sufficient ATP safet...
