Abstract

With the progress and development of the current era, microcontroller technology has spread to our life, work, scientific research and various fields, has become a relatively matu-re technology. This paper introduces an elevator control system based on STC89C52 micro-controller, a detailed description of the scheduling module of an elevator control system,ac-cording to different user needs buttons on each floor, the elevator to make a reasonable jud-gment, know correctly and efficiently finish the passenger elevator, key is connected and eac-h module of the system for the control process a thorough analysis of the elevator control s-ystem under the singlechip software programming and hardware at the same time, each par-t of the hardware circuit were introduced in one one. The elevator control system, singlechi-p microcomputer as the core, supplemented by the floor buttons and the control program co-ntrol the operation of the elevator, and through the digitaltube and the light emitting diod-e to display the realtime operation state of elevator, has the advantages of low cost, versat-ility, flexibility and has the advantages of easy to implementcomplex control, control of the elevator is suitable for us in daily life, wide application prospect.
