AI Technical Summary

Problems solved by technology

Since the working environment of the welding power source is generally harsh and the interference is strong, the application of analog collaboration in the control system of the analog welding power source is not very ideal. In places with strong interference, it may not even work normally.
Therefore, this cannot be applied to the collaborative work of all digital welding power sources.
Solving the cooperative work problem of the full digital welding power source has become an unavoidable problem in the research and development of the full digital welding power source

Abstract

The present invention discloses a welding field synergetic management system based on CAN bus. Said system includes welding power supply control unit, external synergetic execution unit and control zone CAN bus. Every unit of the described welding power supply control unit and external synergetic execution unit is an embedded control unit with CAN bus controller; the described welding power supply control unit and external synergetic execution unit can utilize access of CAN bus to implement communication between both them mutually, and said communication has high reliabity and flexibility.

Description

technical field [0001] The invention relates to a cooperative management system of each sub-system of a full-digital welding power supply system based on a field bus, in particular to a collaborative management system of a welding site based on a CAN bus. Background technique [0002] With the continuous improvement of the world's scientific and technological level, the performance of single-chip microcomputers has been continuously improved, while the price of devices has dropped significantly, which makes it no longer an extremely expensive thing to do embedded industrial control systems. Therefore, the development of embedded development system is rapidly popularized in various related industries all over the world. Correspondingly, the embedded system has also been applied to the welding power source. No matter in foreign countries or in China, all efforts are being made to develop all-digital welding equipment. The welding performance, adaptability and intelligent leve...
