Abstract

The invention discloses a welding machine controlling system using data collection system that includes analog signal collecting circuit module, embedded MCU controlling system module and single chip switch power supply module. The output of analog signal collecting module connects to the input end of A / D converting circuit. The embedded MCU controlling system contains A / D converting circuit used to convert analog signal and storing into RAM. The single chip switching power supply module could supply power for MCU control system module and data collection circuit module to ensure stability. The invention has anti interference, high accuracy, and high reliability.

Description

technical field [0001] The invention relates to a data acquisition system, in particular to a data acquisition system used in a welding machine control system. technical background [0002] With the continuous improvement of our country's scientific and technological level, the domestic welding machine industry has also begun a comprehensive technological innovation. One of the main features is the continuous development of full-digital welding machines to replace the old analog welding machines. The all-digital welding machine can replace the analog welding machine with its own inherent advantages, mainly manifested in the use of embedded system control, which can realize digital precise control and intelligent control, so that the welding machine can be used in welding quality, scope of application, and people. A qualitative leap in computer interaction and other aspects. The reason why the digital embedded welding machine control system can work normally is that the firs...
