基于ZigBee的无线投票系统设计

采用TI设计的高速ZigBee SoC芯片-CC2430,结合ZigBee协议栈,设计了一个基于国际无线通信标准的无线投票系统,它能够在一个空间内快速地建立无线投票网络,支持多节点自由地接入或离开,并且能阻止非法身份节点的进入。系统把路由节点和终端节点设置成通用的投票节点,通过ZigBee网络将这些数据发送到ZigBee网关,网关通过串口与上位机进行通信,并用LabView编写了数据统计界面。测试结果表明,该系统由于采用自组织、自愈合的无线网络,因此性能可靠、方便实用,尤其对于没有有线投票系统的会议室。该系统针对实验教学改革,适用于开展大学生课外科技活动、拓展实践能力。

Design of Wireless Voting System Based on ZigBee

Adopting high-speed ZigBee SoC chip-CC2430 which was designed by TI,combining with ZigBee protocol stack,a wireless voting system based on international standard of wireless communication was designed.It can quickly build a wireless voting network in a space that support multi-node access or leave freely and can prevent illegal identity node entry.The system sets up routing node and terminal node to be universal voting node.The datum was sent to the ZigBee gateway by ZigBee network,gateway communicate with upper computer through cluster communication port（COM）,and data statistics interface was programmed by adopting LabView software.The test results show that this system＇s performance is reliable,convenient and practical due to adopting wireless network of self-organizing and self-union,especially for the meeting room without wired voting system.Major in experiment education reform,this system is suited to develop the extracurricular science and technology activities of undergraduate student,expand practical ability.
