Abstract

The invention discloses a welding machine fault diagnosis method and system, and the method comprises the following steps: collecting welding machine data in each fault state, and constructing a database; preprocessing the welding machine data in the database to generate a training data set; training a hidden Markov model by using the training data set, and generating fault state models corresponding to different fault states; and monitoring the state of the welding machine in real time based on the fault state model. According to the method, the fault position and the fault mode of the welding machine can be determined by analyzing and calculating the fault state model of the welding machine and the real-time collected data, so that technicians can determine a fault solution conveniently.

Description

technical field [0001] The invention belongs to the field of fault diagnosis, in particular to a welding machine fault diagnosis method and system. Background technique [0002] In the development of modern industry, welding technology plays an indispensable role. With the promotion of welding technology, as an important part of the welding process, welding machines have also been widely used. The welding machine has the advantages of simple operation, convenient use, and strong welds after welding. It can be used in various industrial fields such as aerospace, ships, and automobiles. [0003] However, due to the increase in the service life of the welding machine and the influence of the environment on the electronic components, many types of failures will occur. Common welding machine failures include: welding overheating, low no-load voltage, unadjustable current, and air switch tripping after power transmission. The interior of the welding machine is composed of multip...
