High-speed rail and subway gear box operation monitoring and fault diagnosis system

Abstract

The invention discloses a high-speed rail and subway gear box operation monitoring and fault diagnosis method and system and a gear box. The method comprises the specific steps of respectively detecting the state data of the gear box through a sensor located in the gear box, and obtaining the temperature of the gear box, the turbidity of oil in the gear box, the operation speed of a motor train unit, and the vibration quantity data of a gear; acquiring the temperature of the gear box, the turbidity of the oil in the gear box, the operation speed of the motor train unit, and the vibration quantity data of the gear, and transmitting to a micropragrammed control unit (MCU) in real time; and preprocessing received data through the MCU, and transmitting the preprocessed data to a background algorithm processing and monitoring system, and processing the received data and analyzing and judging the fault type of the gear box through the background algorithm processing and monitoring system.

Description

technical field [0001] The invention belongs to the technical field of fault monitoring, and in particular relates to an operation monitoring and fault diagnosis system for high-speed rail and subway gearboxes. Background technique [0002] The gearbox is a key component of the EMU, and the operating state and performance of the entire EMU are directly affected by its operating state. Without affecting the normal operation of the EMU, it is of great significance to realize the analysis of the operating state of the gearbox of the EMU, obtain the fault status and judge it as soon as possible, and discover the hidden faults. [0003] For the analysis of the operating state of the EMU gearbox, it can be evaluated from multi-dimensional data such as gearbox temperature, vibration, oil, stress, and EMU operating mileage. With the development of electronic testing technology and the Internet of Things, the "intelligent" diagnostic technology that integrates modern sensor technolo...
