Abstract

The invention discloses an embedded data acquisition system-based mechanical fault diagnosis device of a mining fan. The embedded data acquisition system-based mechanical fault diagnosis device comprises an intrinsically safe sensor, an embedded data acquisition system and a fault judgment system, wherein the intrinsically safe sensor comprises an intrinsically safe acceleration sensor, an intrinsically safe temperature sensor and an intrinsically safe rotating speed sensor; the fault judgment system comprises an online monitoring module, a fault diagnosis module, an alarming and maintaining module and a data storage module; and the intrinsically safe acceleration sensor, the intrinsically safe bearing temperature sensor and the intrinsically safe magnetoelectric rotating speed sensor are connected to the online monitoring module, the fault diagnosis module, the alarming and maintaining module and the data storage module by an input interface of the embedded data acquisition system and an output interface of the embedded data acquisition system through circuits. The embedded data acquisition system-based mechanical fault diagnosis device disclosed by the invention is used for monitoring the parameters, such as vibration quantity, temperature, rotating speed and displacement on line when the fan works, diagnosing the mechanical faults of the fan and providing corresponding solutions and is suitable for the online monitoring and mechanical fault diagnosis of various fans.

Description

(1) Technical field: [0001] The invention relates to a mechanical fault diagnosis device, in particular to a mining fan mechanical fault diagnosis device based on an embedded data acquisition system. (2) Background technology: [0002] Coal mine (ventilation) fan is one of the important equipments for safe production in coal mines. It operates 24 hours a day and is responsible for delivering fresh air underground and removing dirty air such as dust. Once the coal mine ventilator malfunctions, the underground gas concentration rises to a certain level, which in turn causes coal mine gas explosions, endangering the lives of miners and affecting the safe production of coal mines. Therefore, it is very necessary to carry out online monitoring of the operation status of the coal mine fan (especially the working status of the fan bearing). [0003] At present, the operating state monitoring and fault diagnosis system of electromechanical system adopts stand-alone monitoring and d...
