| 摘 要： | 依据所有蓝牙设备地址的唯一性,设计了基于ARM7控制器的手机蓝牙考勤系统。系统使用手机蓝牙设备作为签到人员唯一的身份标识,以替换传统签到用磁卡。该系统采用LPC2138控制器以AT指令集方式控制核心为BC417143的CSR蓝牙模块,通过查找有效范围（≤20m）内的蓝牙设备地址,并与已注册信息相比对,实现快速、准确的自动签到、显示和语音播报功能。测试结果表明,该系统具有反应速度快,通过率高等优点,可完全实现对传统考勤系统的升级与替换。

| Abstract: | To replace the traditional card attendance system,this innovative design of built-in Bluetooth cell phone attendance system based on ARM7 controller uses the unique Bluetooth device address of each cell phone as a specific attendance sign.AT command sets is adopted for LPC2138 microcontroller to control the CSR Bluetooth module core of BC417143.By searching the Bluetooth addresses within the effective range（≤20m） and comparing with the registered database,fast and accurate auto-sign,info display and voice report can be realized.Result shows that the speed and throughput of this system is of high level,and it can be used as a substitution of the former products. |
