摘要
介绍了教学型电梯模型的总体方案,以及其结构和控制系统的设计.该模型为5层楼电梯控制,电机由24V直流电源供电,楼层信息由8255和74LS245驱动LED管显示.采用Visual Basic可视化语言进行程序设计,界面简单,易于操作.采用计算机控制技术设计了电梯模型控制系统.
Elevators are widely used in modern living.The overall scheme design of the elevator,including the structure design and the control system,is presented.The model provides the control of the elevator for a five-floor building.The power supply for the elevator is a DC power supply of 24 V.The floor information is displayed by the LED tube derived by 8255 and 74LS245 chip.The interface is based on Visual Basic and easy to operate.The control of the elevator model is realized by computer control technique.
