摘　　要：为了实现底片张数定位以及自动统计、自动片尾检测、底片张数存储的功能,设计了一种基于AVR单片机控制的底片自动定位系统的方案与软硬件实现,分析了该系统的硬件组成和软件程序流程,由键盘/显示模块、光电传感器、电机驱动和电源供电模块组成。测试结果表明,该系统具有结构简单、操作简便、性价比高、体积小、自动化程度高等特点。To achieve the functions such as automatic location, automatic statistics, rear film measurement and storage of the films amount, a scheme of films＇ automatic location system based on AVR MCU is designed, whose hardware composition and software implementation are analyzed. The system is composed of keyboard and digital display module, photoelectric sensor, motor drive and power supply module. The experiment results show that the system has many advantages such as simple structure, easy operation, high quality but low price, small cubage and high degree of automation etc.
