摘要
针对现有的图书馆自动借阅系统存在体积庞大,工作运行时能耗高的问题,设计一种基于嵌入式技术的图书馆自动借阅系统。选择三种不同的嵌入式主控芯片满足整体架构的功能需求,并设计子母板切换CPU,重新设计RFID阅读器使其高度集成,减少体积。设置串行通信字符格式,通过计算字符轨道相似度完成匹配,减少数据库冗余数据,节省不必要的能耗。通过能耗测试结果表明,24 h内,现有的系统比设计的系统能耗高出16.8 kW·h时,验证了设计的系统能够降低能耗。
The existing library automatic lending system has a huge volume and high energy consumption during operation.Therefore,a kind of library automatic lending system based on embedded technology is designed.In the hardware design,three different embedded master control chips are selected to meet the functional requirements of the overall architecture,the submotherboard is designed to switch the CPU,and the RFID reader is redesigned to make it highly integrated and reduce the volume.The serial communication character format is set in the software design,and the matching is achieved by calculating the similarity of character track,which can reduce the redundant data of database and avoid unnecessary energy consumption.The results of energy consumption test show that the energy consumption of the existing system is 16.8 kW·h higher than that of the designed system within 24 hours,which verifies that the designed system can reduce energy consumption.
