Description

technical field [0001] The invention relates to a data acquisition and wireless transmission system, which belongs to the technical field of single-chip microcomputers. Background technique [0002] With the development of computer and network technology, the manufacturing industry has been developing from traditional manufacturing to informationization and intelligence. As an important mechanical processing method, welding is often due to the large number of welding workshop equipment and large area in the production of enterprises. The reason makes the management of the welding workshop difficult, and it is easy to cause energy waste and difficult production management. In welding production, problems such as welding machine standby for a long time, welding process parameters being changed arbitrarily, and abnormal welding process have been plaguing manufacturing enterprises, which may easily cause energy waste and product quality problems. At present, methods such as sta...

[0002] With the development of computer and network technology, the manufacturing industry has been developing from traditional manufacturing to informationization and intelligence. As an important mechanical processing method, welding is often due to the large number of welding workshop equipment and large area in the production of enterprises. The reason makes the management of the welding workshop difficult, easy to cause energy waste, and difficult production management

In welding production, problems such as welding machine standby for a long time, welding process parameters being changed arbitrarily, and abnormalities in the welding process have been plagued by manufacturing enterprises, which may easily cause energy waste and product quality problems.

At present, statistical analysis, data tracking, parameter reports and other means are generally lacking in welding production, which affects the optimization of welding process

Due to the lack of welding parameter monitoring and acquisition system, it is currently impossible to conduct direct comparison and analysis of welding quality and welding parameters in welding enterprises, so it is impossible to propose accurate welding parameter optimization schemes in the production process
