可编程时控器及其在地震台的应用

PROGRAMMABLE SEQUENTIAL CONTROLLER AND ITS APPLICATION TO THE SEISMOSTATION

可编程时控器的原理是用电子数字钟的时间显示,经过适当组合、逻辑变换作为地址代码,直接在静态随机存贮器中写入或读出有关的操作指令,由此构成了一个新颖的时序控制器。这种时序控制器在武汉地震台的技术管理应用中,获得了良好的效果。

It is the principle of the programmable sequential controller that the time display of the electrodigital clock is used to be the address code undergoing the proper combination and logical transfer, and the corresponding operational order is immediately written in or read out from the static random storage, therefrom a new sequential controller is formed. This controller is applied to the technical management at wuhan seismostation and a good effect is obtained.
