Problems solved by technology

[0004] 1. When the speed of the train is high, it can also be manually isolated or bypassed, and there are unsafe factors
[0005] 2. The isolation of the ATP system at the inactive end of the train requires manual operation
[0006] 3. There is no feedback on the state of the isolation device, and the normal and effective output of the isolation cannot be guaranteed

Embodiment Construction

[0026] The present invention will be described in detail below in conjunction with the accompanying drawings, and the features of the present invention will be further revealed in the following detailed description.

[0027] figure 1 is a schematic diagram showing the design principle of ATP system isolation according to one embodiment of the present invention.

[0028] like figure 1 As shown in , a set of ATP equipment is installed at both ends of the train (I end and II end). Each set of ATP equipment may be electrically coupled to the same train electrical circuit via ATP isolators (not shown) at respective ends. The ATP isolation device can be configured to receive the control signals from the driver's key and the manual isolation switch at the corresponding end, and properly isolate the ATP equipment based on the received control signals to ensure that only one set of ATP equipment can output to the train electrical circuit at the same time ATP signaling.

Abstract

The invention provides an ATP (automatic train protection) system isolation method and device. The ATP system isolation device comprises a manual isolation circuit, a driver key isolation circuit andan isolation device, wherein the manual isolation circuit is used for responding to determination that the real-time speed of a train is zero and a manual isolation switch is closed, and providing manual isolation signals, the driver key isolation circuit is used for acquiring key activating signals, responding to the acquired key activating signals, indicating that a key is non-activated and providing driver key isolation signals, and the isolation device is used for responding to any one of the received manual isolation signals and the received driver key isolation signals, and outputting isolation output signals to isolate output of ATP equipment.

Description

technical field [0001] The invention relates to the field of train signal control, and more specifically, to an isolation method and device for an automatic train protection system. Background technique [0002] In the train signal control system such as the urban rail transit signal system, the automatic train protection system (Automatic Train Protection, ATP) is one of the key signal devices responsible for the safe operation of urban rail trains. The ATP system detects the speed and location of the train in real time; monitors the operation of the train based on the acquired movement authorization, current line status, and the position of the preceding train to prevent the train from exceeding the speed limit or crossing the end point of the movement authorization to ensure the safety between trains The driving interval distance realizes the automatic safety protection operation of the train. [0003] There are driver consoles at both ends of the urban rail train, and a...
