微机控制电梯的升降运行,数字式的呼梯信号和平层信号是不可或缺的。通常,我们从每层电梯间的申请控制盒和平层开关都要向主控台引出呼梯信号线和平层信号线,如果楼层较多,就需要很多的控制线,而且这些控制信号要进行编码,才能供主控台使用。本人设计制作了一套以单片微机为控制核心的9层无人载货电梯的电气控制系统,获得了成功。现将该系统的呼梯信号和平层信号的形成电路摘录出来,仅供读者参考。
Computer-controlled elevator movements, digital call signals and leveling signals are indispensable. Normally, we apply call signal lines and leveling signal lines to the master station from the application control box and the leveling switch in each elevator. If there are many floors, a lot of control lines are needed, and these control signals are encoded , Can be used by the console. I designed and manufactured a set of 9-floor unmanned electrical elevator control system with single-chip microcomputer as the control center, and achieved success. Now the system call signal and the formation of flat-layer signal extracted from the circuit, for reference readers.
