Platform door and signal interface state monitoring device

Abstract

The invention, which relates to the technical field of electrician preparation and application, provides a platform door and signal interface state monitoring device. The device comprises a voltage quantity monitoring conversion module, an analog quantity acquisition device, a central processing module and output display equipment. The input terminal of the voltage quantity monitoring conversion module is connected with interfaces of platform door side and signal side equipment, and the output terminal of the voltage quantity monitoring conversion module is connected with the input terminal ofthe analog quantity acquisition device; the analog quantity acquisition device is connected with the central processing module; and the output terminal of the central processing module is connected with the input terminal of output display equipment. The device monitors and analyzes the state signals of the platform door and the signal interface in real time, so that when a fault occurs, the fault reason and the fault position can be visually displayed at the first time; and thus the maintenance personnel can conveniently and quickly maintain and process the fault, so that the troubleshootingprocessing time is greatly shortened.

Description

technical field [0001] The invention relates to the technical field of electrical preparation and application, in particular to a state monitoring device for a platform door and a signal interface. Background technique [0002] The failure of the interface between the platform door system and the signal system directly causes the train and the platform door to be unable to be linked or there is no fully closed signal, which affects the traffic order and has a greater impact on the fault; and such failures involve the platform door system and the signal system, fault analysis and judgment Difficulty; at the same time, during normal operation, the actual allowable repair processing time is very limited. [0003] At present, the interface between the existing platform equipment and signal equipment is only a terminal block. When a fault occurs between the platform door and the signal interface, because it involves the platform door system and the signal system, the fault lasts ...

[0002] The failure of the interface between the platform door system and the signal system directly causes the train and the platform door to be unable to be linked or there is no fully closed signal, which affects the traffic order and has a greater impact on the fault; and such failures involve the platform door system and the signal system, fault analysis and judgment Difficulty; at the same time, during normal operation, the actual allowable repair processing time is very limited

[0003] At present, the interface between the existing platform equipment and signal equipment is only a terminal block. When a fault occurs between the platform door and the signal interface, because it involves the platform door system and the signal system, the fault lasts for a short time and recovers instantaneously. It occurs frequently, and it is difficult to analyze and judge the fault. Large, it is not convenient for troubleshooting and troubleshooting. After the fault occurs, it will have a great impact on the normal operation of the subway
