基于Android系统的RFID手持终端低功耗设计

Low-power consumption design of RFID handheld terminal based on Android system

文中研究的Android系统的RFID手持终端主要进行电能表数据的抄读,在实际使用中电池续航时间要求较长,因此,降低手持终端系统的功耗成为研究的重点内容。首先分析了影响系统功耗的因素,详细介绍了动态消耗,并从硬件和软件两个方面讨论了降低系统功耗的措施。在RFID手持终端的微处理器以及外围芯片的选取中,尽量选取低功耗的元件,最后对RFID手持终端的功耗进行了测试,并对测试数据进行了相应的分析。

The RFID handheld terminal of Android system mainly studies the reading the data of electric energy meter.The battery needs longer life time in actual use. Therefore,how to reduce the power consumption of handheld terminal system has become the focus of the research. This paper firstly analyzes the factors that affect the power consumption of the system,introduces the dynamic consumption in detail,and discusses the measures to reduce the system power consumption from two aspects of hardware and software. In the selection of microprocessor and peripheral chip for RFID handheld terminal,we try to select low-power consumption components. Finally,we test the power consumption of RFID handheld terminal and make a simple analysis of the test data.
