摘要
以单片机89S8252为核心,开发了一种可以远程控制的多路数字延迟脉冲发生器。其主要输出参数为:重复频率1~1000Hz可调,时间延迟0~60ms可调,精度分为1“s和0.1μs两种,发生器输出脉冲可以直接驱动多路可控硅,工作方式分为远程控制和外部触发两种。该发生器已用于高功率微波驱动源的控制中,抗干扰能力强,工作可靠。
A remotely controlled pulse generator was developed with SCM 89S8252 as CPU. It has an adjustable repetitive rate of 1-1 000 Hz, an adjustable time delay of 0-60 ms, a step value of μs or 0.1 /2s. Its output pulses can directly drive SCR. It can be controlled either by a remote computer or an external trigger mode. Experimental results indicated that the generator worked well against the electromagnetic interference caused by the pulse power system.
