Abstract

The invention provides a crusher system fault diagnosis method and device, and relates to the technical field of fault detection.The method comprises the steps that firstly, a first parameter is generated through a pre-established offline model; the first parameters comprise the order, the sampling period and the data set length of the offline model; then determining a fault diagnosis monitoring quantity based on the first parameter and a second parameter acquired on line; the second parameters comprise a crusher load parameter and a feeder load and frequency product parameter; if the fault diagnosis monitoring quantity exceeds a first threshold value, the crusher system has a fault, and the fault type of the crusher system is determined. By means of the method, the technical problems that part of parameters are difficult to collect and the fault diagnosis cost is high can be solved, and the technical effects of reducing the cost and improving the detection precision are achieved.

Description

technical field [0001] The invention relates to the technical field of fault diagnosis, in particular to a method and device for fault diagnosis of a crusher system. Background technique [0002] Crusher is a device for crushing the material medium. Through the impact, it can reduce the lumpiness of the material medium. It is widely used in mines, mainly in crushing, grinding and other processes. Usually the crusher is used together with the upstream frequency-adjustable feeder to form a crusher system to crush the feed to the feeder. In the crushing process of beneficiation, the crusher system is the most important link in the whole process. The stable operation of the system directly affects the crushing effect, product quality and production efficiency. If the system fails, it will directly lead to the reduction of equipment efficiency and crushing efficiency, and even system shutdown and production interruption, which will affect the production capacity. [0003] In ac...
