低功耗指纹锁无钥匙门禁系统设计及协议制定

摘要

Based on low power consumption SoC microcontroller C8051F9XX and RF transceiver, remote keyless entry (RKE)hardware system is designed for the transmitting and receiving system, and match event and timing wakening mechanism is expounded for the RKE. The RKE learning and work protocols are established according to keys, pseudo random and AES encryption algorithm,and flowchart of the RKE transmitting software is also briefly introduced. Experimental results show that the fingerprint lock RKE system consumes low power, communication protocols are safe and reliable, and remote keyless locking and unlocking objectives is realized.%基于低功耗SoC微控制器C8051F9XX及RF收发器,设计了指纹锁遥控无钥匙门禁的发射和接收硬件系统,阐述了无钥匙门禁系统事件匹配和定时唤醒的工作机制.根据密钥、伪随机数及AES加密算法研究制定了指纹锁无钥匙门禁系统学习协议以及遥控操作工作协议,并简要介绍了发射系统软件主要流程.实验结果表明,该指纹锁遥控无钥匙门禁系统功耗低,通讯协议安全可靠,实现了指纹锁遥控无钥匙开关锁的目标.
