The paper designed an elevator controller based on singlechip. The hardware circuit of the controller,which is mainly used for floor display, moving direction indication and input of floor request signal,is simple and reliable. The software part of elevator controller followed three priority principles so as to reduce the response time of request, which has improved the efficiency of the elevator. Test results show that the controll system is stable.According to software simulation and hardware circuit,elevator controller achieved predetermined goal and can be further extended for the needs of different floors.
