Experimental study on control of selective-collective elevator drive system using microcomputer

마이크로콤퓨터에 의한 방향성 승합 엘리베이터 운전 시스템 제어의 실험적 연구

This paper deals with the drive contrl of common elevator systems which may be realized with .mu.p-controlled selective-collective elevator systems. Incorporation on non-contact point circuits instead of electromagnetic relays in such an elevator system results in miniaturization of complicated hardware controllers currently being used. The drive control method is implemented by software programming. The important features are not only technical advantages such as higher performance, high speed data processing and more improved reliability, but also lower cost as compared with the conventional elevator drive control units equipped with a number of sequential electromagnetic relays and even more recent static IC logic circuits.
