摘要
为满足手持抄表终端对快速准确、低功耗、低成本的需求,设计一种基于S3C6410的低功耗RFID手持抄表终端。基于高性能、低功耗的S3C6410芯片和CLRC632射频芯片实现非接触式RFID读写操作,并配套设计了人机交互模块、电源管理模块、读写模块等电路。在综合考虑手持终端的功耗、成本、电源稳定性、数据传输的安全性、人机交互的友好性等因素的基础上,进行手持终端的硬件及软件的设计。最后对其功耗进行了测试,试验表明相比于同类型产品具有待机时间更长、功耗更低的优点,具有推广应用价值。
To meet the requirements of handheld meter reading terminal for celerity and accuracy,low power consumption and low cost,a low power RFID handheld meter reading terminal based on S3C6410 is designed.Based on high-performance,low-power S3C6410 chip and CLRC632 RF chip,non-contact RFID read and write operations have been achieved,and the matching design of the human-computer interaction module,power management module,read and write modules and other circuits has been finished.The factors such as the power consumption,the cost,the power supply stability,the security of the data transmission and friendly human-computer interaction are considered to carry out the hardware and software design of handheld terminals.The experimental results show that the meter reading terminal has the characteristics of fast and accurate group copying,low power consumption and low cost,and has the popularization and application value.
