In the base of PC_Based Control, automatic control system can be run smmothly on Windows 2K/XP platform by integrating with PC technique, signal measurement and analysis technique, control technique, communication technique and Windows NT technique A. Intelligent processing capability As the each operating point has the intelligent processing capability, even if the multiple point of system fail(not more than 1/3) at the same mtime, the whole system still can work well. It makes the system have a super stability. B. Open module structure This control system adopts open module structure. According to actual demands it can make a correction, addition or subtraction under single module or multi-modules condition at any time to keep system advanced. C. Self-adaptability on site Because of perceptive technology, the system can make the relevant sdjustment in 3minutes to adapt any influencing factors. D. Self-learning ability Based on the collected data (the parameters of working temperature, electric current, gap and frequency etc), the system adopts algorithm which has self-learning function and also equips open database with super capacity. It makes the system have the capacity of learning and the communication with external environment to select the best control parameter and ensure high effciency of production equipment. E. The function of remote monitoring and control The internet communication module of automatic control system realizes the function of remote monitoring and control. F. High-speed data exchange capability with open data source of Windows, Unix, Linu operating system Ininternet system, the high-speeddata pipe which exchange data with standard open data source can realize the seamless connection as long as the standard data source supported. G. High security The system adopts safety management which combined safe area with priority limit, meanwhile, because of the sense ablity; the system also can transit to automatic condition smoothly even if it suffered heavy accident to have to turn to manual control condition.
