Intelligent fault detector for passenger train vacuum excrement collecting device

Abstract

The invention relates to an intelligent fault detector for a vacuum excrement collecting device of a passenger train. An online detection mode is adopated, through a specialized transition joint, a detection device is connected with a vacuum excrement collecting device control module (LCU), input and output signals of the control module (LCU) are directly obtained in an intruding mode, the obtained signals are processed and then transmitted to the mobile phone APP in a wireless mode, the signals are displayed by the mobile phone APP, and system detection and fault diagnosis of the vacuum excrement collecting device are completed. The intelligent fault detector for the vacuum excrement collecting device of the passenger train can rapidly detect and judge faults of electronic components, isbeneficial to field maintenance, and enables operators to rapidly find and eliminate the faults.

Description

technical field [0001] The invention relates to an intelligent fault detector for a vacuum toilet collection device of a railway passenger car. Background technique [0002] At present, most domestic railway passenger cars use the following methods to detect the failure of the vacuum toilet device: [0003] ①Installation and inspection of the inspection table; [0004] ②Manual inspection; [0005] Inspection bench installation and inspection: The inspection table installation inspection is the inspection method of the vacuum stool collection device manufacturer when it leaves the factory. It can comprehensively inspect the vacuum stool collection device to ensure the vacuum stool collection device before loading integrity. [0006] Limitations of Bench Testing: [0007] 1. A fixed testing machine and a large testing place are required; [0008] 2. After the vacuum toilet device is loaded and used, it cannot be carried out on the bus. [0009] Manual inspection: The man...
