把几个单稳态电路依次连接起来便可实现对某些时间顺序过程的控制.在一般控制精度要求不很高的场合下,由于它简单易作且经济可靠,故应用很普遍.但是,在实际的控制过程中常常因故需要突然改变原定的程序,比如临时中断、延长某一过程或提前换行其它过程等,这时仅仅依靠简单级联的单稳程控电路便不能胜任了.这里介绍一种改进了的单稳程控电路,它能通过强制触发的方式按人为所需迫使程控过程作临时调整与变更.
Several monostable circuits in turn connected to achieve some of the chronological process control in the general control accuracy is not very demanding occasions, because it is simple and economical and reliable, so the application is very common, however, In the actual control process often need to suddenly change the original program, such as temporary interruption, to extend a process or pre-wrap other processes, then only rely on simple cascaded single-stable control circuit will not be competent. An improved monostable programmable control circuit is introduced, which can be forced to adjust and change the programmed process by means of forced triggering.
