基于Zigbee的无线传感器网络四驱小车系统设计

System Desgin Four-Wheel-Drive Car Based on Zigbee Wireless Sensor Network

研究了基于Zigbee的无线传感器网络四驱小车的综合训练平台。采用现代电子技术创新设计平台,是一款集教学实训、创新设计、科研开发于一体的综合性实验平台。平台以智能小车为载体,以STM32、STC12C5A60S2单片机为核心控制单元,包含显示、按键输入、传感器数据采集、物联通信、运动控制、物料的抓持和搬运等单元。Zigbee模块核心采用的是CC2530。CC2530结合了领先的RF收发器的优良性能,具有不同的运行模式,使其尤其适应超低功耗要求的系统。因此,系统运行模式之间的转换时间短,确保了低能源消耗。

In this paper,the comprehensive training platform of four-drive trolley based on Zigbee wireless sensor network is studied,a modern electronic technology innovation design platform,is used as a comprehensive experimental platform which integrates teaching training,innovative design and scientific research and development.The platform takes the intelligent car as the carrier,takes STM32,STC12c5a60s2 single chip microcomputer as the core control unit,including display,keystroke input,sensor data acquisition,physical communication,motion control,material grasping,handling and so on.The core of Zigbee module is CC2530.CC2530 which combines the excellent performance of the leading RF transceiver.CC2530 has different operation modes,which makes it especially suitable for ultralow power consumption requirements.The short conversion time between operation modes further ensures low energy consumption.
