摘要
为提高自行车存放的安全,设计一套无人值守自行车存放系统。该系统利用RS-485总线进行通信,结合键盘管理芯片、点阵式LCD、微型打印机、电磁锁以及对射式红外线收发器等部件,实现了存车、取车、防盗、报警、特殊事件处理功能,具有安全可靠、使用方便、施工简单等特点。
Designs an unattended bicycle depositary system based on multi-computer communication technology, By using RS-485 bus technique, keyboard chip, LCD, mini printer, electromagnetic lock, infrared sensors, the system anticipative functions such as bicycle parking, bicycle taking out, guard against theft and giving an alarm have been realized, And it is secure, convenient and easy to install.
