Study On The System Of Monitor For Resistance Spot Welding Based On CAN Bus

Resistance spot welding is one of the most important welding processes. It is extensively used in modern industry, especially in automotive industry and aviation, for its high-density energy, simple operation, high productivity, and high automation. As the fabrication technique develops, the request for the welding quality and reliability is increasing. According to the investigation, spot welding quality could be mastered by real time technical parameters monitoring. It has important meaning to guarantee the welding quality. Along with the development of the spot welding quality supervise and control technique, especially microcomputer technique and intelligence control application in industry control, some of the late-model micro controller spot welding quality control equipments are gradually expanding. As a whole, control mode has been developing from single mode control into multi-mode control; regulation parameters have been developing from single variable regulation into many variables regulation; control decision has been developing from normal control decision method into artificial intelligence decision method. In recent years, along with the fast development of electronic technology and the application of computer, single chip processor technology was extensively used in resistance spot welding quality control in modern industry manufacture. At the same time, as the extending of production scale, the problem of "information lone island"become more and more seriously; meanwhile, with the rapid development of network technology and industrial controller LAN (Local Area Network) technology, the application of industry teleautomatics technology became more widely, It is the industry technique application hotspot of using the local machine to control the industrial field machines by LAN. Therefore, people were anxious that such supervising and controlling system based on network could be practicable. Then, it is with great importance to develop and perfect resistance spot welding technology by go deep into study spot welding monitoring and controlling system based on...
