摘要
目前在智能锁通信架构普遍采用WiFi、蓝牙、ZigBee等通信技术和IPv4协议,不能兼顾长距离传输和低功耗的需求,存在管理不便、安全性较低、IP地址匮乏等问题;针对这些问题,设计了一种基于IPv6和LoRa的智能门锁系统,系统由执行层、网络层、服务层和应用层四部分组成;门锁终端采用STM32L151CBU6微控器为主控制器,在云服务器上部署LoRa服务器和Java Web应用实现系统的管理和控制;测试表明,一个网关可覆盖一栋约11层楼的有效区域,一节1000 mAh电池可用1.8年,该系统拥有功耗低、通信距离长、安全性高等优点。
Communication technology,also knows as WiFi,Bluetooth,ZigBee and IPv4 protocol,is widely used in the intelligent lock communication architecture,the needs of long-distance transmission and low power consumption cannot be considered,resulting in problems such as the inconvenient management,low security and lack of IP addresses.In order to solve these problems,an intelligent door lock system based on the IPv6 and LoRa is designed.The system consists of four parts:execution layer,network layer,service layer and application layer.The lock terminal for the primary controller is used by the STM32L151CBU6 microcontroller,and the LoRa server and Java Web application are deployed on the cloud server to manage and control the system.The test data shows that a gateway can cover the effective building of about 11 floors,and a 1000 mAh battery can be used for 1.8 years.The system has the advantages of low power consumption,long communication distance and high security.
