| Abstract: | 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. |
