基于RFID的微电脑无线巡更系统的设计与实现

摘要：针对一般采用计算机记录巡更信息的巡更模式，本文设计了一种新型的微电脑无线巡更系统，包括改进的微电脑巡视记录仪、手持巡更器以及站点信息钮。本系统以低功耗、高性能的PIC单片机为控制核心：微电脑记录仪初始化各手持巡更器，并对巡视站点信息钮进行认证；手持巡更器采用了无线射频识别技术，实现了对认证的各个巡视站点信息钮数据的采集，通过串口连接微电脑记录仪来读取信息，并打印出来，达到了正确记：录巡视人员巡视时间等的目的。系统采用了自行编写的通信协议，操作简单，便于管理，能有效的提高安防工作的效率，具有一定的：实用和应用价值。

The Design and Implementation of Microcomputer Wireless-patrol System Based on RFID

For the general patrolling of recording information on the use of computer,this paper design a new type of microcomputer wireless-patrol system,including the improved microcomputer recorder,handheld patrol device and iButton.The system adopts the MCU which has low power consumption and high performance as its main microprocessor.The microcomputer recorder initializes the handheld patrol device,and authenticates the iButton.The handheld patrol device uses the radio frequency identification(RFID) technology,a...
