摘要
介绍了基于单片机的自动售货机控制系统设计,该系统以单片机AT89C52作为主要控制单元,由扫描键盘按键值来控制显示待售量和电机转动推出货物,硬币识别采用光电传感器GK-310C型光电管实现,并采用寄存器实现所投硬币计数;用七段数码管显示货物待售量并采用独立式按键实现货物选择。该设计结构简单,方便操作,适用于要求不高的小型零售场合。
This paper introduced the design of vending machine control system based on the Single-Chip Microcomputer. The design used Single-Chip Microcomputer of AT89C52 as control unit, used value of scanning keyboard to control and motor driver, and used the electro-optical sensor GK-310C to identify value of the coin and so on. This design is simple in structure, convenient operation, applicable to the requirements of small retail occasions.
