| 摘 要： | 本文对电脑型可控硅焊机的软件触发技术进行了深入的研究。提出了利用 CTC 的一个通道进行重复定时的定时方式,这种定时方式具有硬件电路简单,动态响应灵敏度高的特点。采取软件触发后,使焊机的调试工作及触发电路大为简化。这种软件触发技术不仅可以应用在电脑型可控硅焊机上,也可以应用到其它微机控制的可控硅整流电路中。

| Abstract: | In this paper a software triggering method is discussed in detail for the microcomputer controlled SCR welding rectifier.The principle of the method presented is to make repeat timing in one of the CTC timing channels.This method has the advantage of simplified hardware and high dynamic responsib- ility.The adjustment job and the trigger circuits of the SCR welding mach- ine can be greatly simplified by using the software trigging method.The method can be applied to other SCR rectifying circuits controlled by microco- mputers. |
