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 disadvantages of traditional monitoring system, a remote monitoring system based on Internet of Things technology and fingerprint identification technology was designed. The CC2530 chip is used to set up the ZigBee technology network and control core. The fingerprint sensor AES2510 is used for fingerprinting. The high-performance general packet radio service module MC39i is used for remote network connection, which makes the system have low power consumption, High reliability, low cost and remote controllable features. Experiments show that the system has a fingerprint identification accuracy of 100%, transmission range of 150 m, communication baud rate up to 35 kb / s at 100 m, current only 2.5 uA during sleep and reception power of 82 dBm, which meets the actual requirements .
