摘要
文章从硬件及软件方面介绍了TagMaster AB公司的RFID手持阅读器电源管理的设计。在硬件设计方面,手持阅读器采用了Atmel公司的AT91RM9200高性能低功耗微控制器,并利用芯片的电源管理模块控制外设;在软件方面,采用了多种电源管理策略,实现了与外接设备特性相符的电源管理函数。经使用测试,手持阅读器功耗得到了大幅度的下降。
The APM designs of the hardware and the software of TagMaser AB＇s RFID handheld reader are introduced in this paper. The handheld reader adopts AT91RM9200 of Atmel Corporation which is of high performance and of low energy. And the APM module of chips is used to control periphery. Also, many APM policies are used to complete some APM functions corresponding to the peripheral characteristic. By testing, it is very obvious that the consuming of energy is being reduced largely.
