Study on Long-distance Surveillance System based on ZigBee and Fingerprint Identification Technology

针对传统监控系统的种种弊端,设计一种基于物联网"紫蜂"技术和指纹识别技术的远程监控系统。采用CC2530芯片组建"紫蜂"技术网络和控制核心,利用高灵敏度的指纹传感器AES2510进行指纹采集,并使用高性能的通用分组无线服务模块MC39i进行远程网络连接,使系统具有低功耗、高可靠性、低成本和远程可控的特点。实验表明,系统的指纹识别正确率达100%,传输范围达150 m,在100 m时的通信波特率达35 kb/s,休眠时电流仅2.5 uA,接收功率为82 dBm,符合实际要求。

Aiming at the disadvantage of the traditional surveillance system,a long-distance surveillance system based on ZigBee and fingerprint identification technology is designed.The chip CC2530 is adopted to construct the ZigBee network and control center,while the sensitive sensor AES2510 is utilized to acquire fingerprint,and the high-performance GPRS module MC39i to implement connection to the long-distance network.All of this makes the system have low power,high reliability,low cost and long-distance controllability.Experiment shows that the correct designed fingerprint identification rate of the designed system reaches 100%,the transmission range reaches 120 m,the baud rate reaches 35 kb/s when the distance is 100 m,the current is 2.5 uA when the system is in dormancy,the received power is 82 dBm and that the system could satisfy the practical requirement.
