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...

Embodiment Construction

[0017] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0018] Such as figure 1 As shown in the system block diagram of the present invention, the data acquisition system used by the welding machine control system of the present invention is characterized in that it includes an analog signal acquisition circuit module, an embedded MCU control system module and a single-chip switching power supply module;

[0019] The output end of the analog signal acquisition circuit module is connected with the input end of the A / D conversion circuit in the embedded MCU control system module, and is used for filtering various analog signals, a voltage divider circuit, and then selecting through a multiplexing circuit After that, it is filtered again and sent to the A / D conversion circuit as a relatively stable input signal;

[0020] There is an A / D conversion circuit in the embedded MCU control system module, wh...
