KeilC51是一种结构化的语言,具有灵活、高效等优点。利用C51对变极性等离子焊控制系统编程表明,同汇编编程相比,整个程序可读性和结构化较好,算法的实现也较汇编语言简单。可完全满足变极性等离子弧焊设备对电流频率、正负半波导通比等参数的调节和控制的要求。 KeilC51 is a structured language with the advantages of flexibility and efficiency. Using C51 to control the system of variable polarity plasma welding shows that, compared with the compilation of programming, the whole program is readable and structured better, the algorithm is also easier to implement than the assembly language. Can fully meet the variable polarity plasma arc welding equipment on the current frequency, positive and negative half-wave conduction ratio and other parameters of the regulation and control requirements.
