Abstract

The invention discloses a mining fan fault diagnosis system which comprises a sensor, an embedded data collecting system and a fault diagnosis system. The sensor comprises an acceleration sensor, a temperature sensor and a rotating speed sensor, and the fault diagnosis system comprises an online monitoring portion, a data storage portion, a fault diagnosis portion and an alarming repairing portion. The mining fan fault diagnosis system overcomes the defect that in the prior art, the mechanical fault of a coal mine fan cannot be monitored accurately and effectively under the conditions of gas, coal dust and other dangerous environments and severe work environments, the vibration amount, temperature, rotating speed, displacement and other parameters of the fan in the work process are monitored online, the mechanical fault of the fan is diagnosed, the corresponding solving method is provided, and the mining fan fault diagnosis system is suitable for the online monitoring and mechanical fault diagnosis of various coal mine fans.

Description

technical field [0001] The invention relates to a fan fault diagnosis system, in particular to a mining fan fault diagnosis system. Background technique [0002] Coal mine fan is one of the important equipments for safe production in coal mines. It operates 24 hours a day and is responsible for transporting 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 conduct timely and accurate on-line monitoring of the operation status of coal mine fans. [0003] At present, the operating state monitoring and fault diagnosis system of electromechanical system adopts stand-alone monitoring and diagnosis system, centralized monitoring and diagnosis system, online distributed monitoring and diagnosis system based on...
