弧焊电源的智能输入专家系统设计

Design for the intelligent input expert system of arc welding power source

介绍了弧焊电源输入给定方式由模拟给定到数字给定的发展历程。讲述了该焊机在DSP最小系统下的输入设计的特点。该系统仅需16个I/O端口便可完成焊接工艺参数的输入与同步显示,同时满足焊机控制系统的可升级性。在硬件电路中采用4×4键盘数字输入方式,与多显汉字模块的结合使输入系统操作简单化、人性化,加快了实时显示的响应速度。在软件编程中融入了独特的输入专家系统库,该库不仅可为输入系统提供参考,也能在焊接过程中提供校正功能。设计简化了以往的焊接输入操作界面,可实现自主优化焊接输入参数的功能,提高了输入系统的智能性。

This paper introduces the development of that the arc welding power inputting from analog given to digital given,tells the inputting features of the welder in DSP minimum system.The system only has 16 I/O ports that can complete the inputting and synchronous displayed of welding technology parameters,at the same time,makes controlling system of welder to have the scalability.The system uses the digital inputting way which combines the 4×4 keyboard and much shower Chinese module in hardware circuit.It makes the inputting system having the character of operation simplification and human nature,and quick responses of the real-time display.The unique inputting expert system library is used in software programming,it not only provides a reference for inputting system,but also provides the correction function in the welding process.This designing simplifies the inputting interface of previous welding,makes self-optimization inputting parameters,and improves the intelligent of inputting system.
