Problems solved by technology

[0006] And because the ATP system fails, the driver needs to manually find out through the ATP display screen, and then manually isolate the signal system
If the vehicle is running (especially when accelerating and going downhill), if the ATP system host or control circuit fails, the vehicle will immediately lose the protection of the ATP system, but if the driver does not observe it from the ATP system display at the first time ATP system failure alarm or no immediate measures to brake and isolate the ATP system, the vehicle may run at high speed without the protection of the ATP system, which is dangerous for the vehicle and may lead to operating accidents

Embodiment

[0053] This embodiment discloses a vehicle. The ground equipment of the signal system is installed on the vehicle line, which can communicate with the vehicle signal equipment. When the vehicle is running on different road conditions, such as downhill, turning, etc., it will There are different speed limit requirements. When the speed of the vehicle exceeds the speed limit value, the ATP system will trigger the vehicle's braking system to apply the brakes. If the vehicle does not stop immediately when the light turns red, the vehicle's braking system is also triggered.

[0054] The on-board equipment of the ATP system is mainly composed of ATP control host, ATP display screen, all-used brake relay, emergency brake relay, speed sensor, transponder and other equipment. The high level of normal braking means triggering, and the low level of emergency braking means triggering. That is to say, when the normal ATP system does not apply brakes, the normal brake relay is in the de-en...

Abstract

The invention discloses a train automatic protective system safety control circuit, method and vehicle. The train automatic protective system safety control circuit comprises an ATP module and a vehicle emergency braking module, and the ATP module is connected with a vehicle emergency braking relay of the vehicle emergency braking module through an ATP emergency braking relay. When the ATP faults,the ATP emergency braking relay is disconnected, thus the vehicle emergency braking relay is disconnected, and emergency braking is conducted on the vehicle. According to the train automatic protective system safety control circuit, the ATP emergency braking relay is arranged, emergency braking can be automatically applied to the vehicle firstly to guarantee immediate stopping of the vehicle whenthe ATP system faults under any circumstances of the vehicle, and then the operation of separation of the ATP system is conducted by a driver. Even under the extreme case that double faults occur oncritical electric component of the vehicle, automatic traction force cutting off can also be achieved through the vehicle, the speed of the vehicle is lowered, and operation safety of light rail vehicles is improved.

Description

technical field [0001] The invention relates to the technical field of train safety protection, in particular to a safety control circuit of an automatic train protection system, a control method, and a vehicle using the control circuit. Background technique [0002] In the urban light rail transit vehicle system, the signal system is an important system to ensure the safety of the vehicle. The automatic train protection system (ATP system for short) is a kind of signal system, which consists of two parts: on-board equipment and ground equipment. [0003] There are two main functions of the ATP system: one is train overspeed protection. During the operation of the vehicle, if the speed limit of a certain section of the line is exceeded, the automatic train protection system will be activated, and the brake will be automatically applied according to the current overspeed situation to ensure the safety of the vehicle. The other is the safety distance protection between train...
