摘要
针对目前数据管理中心无法获得远程终端数据的问题,提出了一种基于嵌入式GPRS的手持通讯设备的设计。该设备采用AT91SAM7X256嵌入式芯片和无线收发芯片MC35,并给出了详细的软硬件设计方案,最终实现了远程数据的传输。
Aiming at the problem of the data management center being incapable of receiving data from a remote endpoint,an embedded-GPRS-based handheld communication device design is proposed.The device is constructed with AT91SAM7X256 embedded chip and MC35 wireless transceiver chip.Detailed software and hardware design scheme is provided.Remote data transmission is thus realized.
