摘要
以AT89C51单片机为核心,使用12位并行A/D转换器AD574A、多路开关CD4051、无线发射芯片MI-CRF102及接收芯片MICRF002,设计了一款农业机械状态测试系统,并对数据采集部分AD574A与AT89C51的接口技术、无线收发机的实现、硬件和软件设计过程做了详细阐述。
A system used to testing the state of agri -machine is designed, which take the AT89C51 singlechip as the core, and uses the 12 -bits A/D converter AD574A, multiplexer CD4051, wireless transmitter IC MICRF102 and receiver IC MICRF002. In this paper, interface technology AD574A to AT89C51 of collectingdata part and the achieving of wireless receiver/transmitter are described in detail, including hardware and software.
