基于云平台的智能门锁控制系统开发

AN INTELLIGENT LOCK CONTROL SYSTEM BASED ON CLOUD PLATFORM

目前门锁控制系统在联网、实名认证以及房卡的信息安全性等方面存在缺陷,不能够很好地适用于短租房和酒店管理。针对上述问题,采用模块化设计思想,设计开发一种支持云平台通信的智能门锁控制系统。该系统主要包括门锁端、云平台以及手机端APP三部分。门锁端支持数字密码操作,并支持基于KMP算法的虚位密码功能。同时可识别身份证进行身份认证,并通过云平台将信息传到手机端以检测用户是否已在系统上实名注册。控制单元以STM32为核心,嵌入Wi-Fi模块与云平台交换信息。云平台采用京东微联实现,用于实现门锁端和手机端的信息互联。手机端主要针对H5界面和控制逻辑进行开发,用户可在手机端录入身份信息,传到门锁进行实名登记注册。系统还可通过Wi-Fi通信实时地将门锁状态以及操作信息经云平台传输到手机端,实现对房间安全防护的远程监控。

Owing to their flaws in terms of net-working, real-name authentication and information security of house cards, current door lock control systems are often not capable to be applied to short-term renting and hospitality management properly. Aiming at these problems, this paper designed a new type of door lock control system which supports cloud communication under the concept of modular design idea. The proposed system consists of three main parts: door lock, cloud platform and mobile phone terminal. The door lock supported digital password operation and virtual password based on KMP algorithm. The system could identify ID cards for user identity authentication while transmitting information to the mobile phone APP through the cloud for real-name certification. The control unit of the lock, based on a STM32 microcontroller, integrates the Wi-Fi module to communicate with the cloud platform.JoyLink, as a cloud platform for data storage and processing, brought the interconnection of information on door locks and mobile phones. Mobile phone APP was developed based on H5 interface and control logic, and users could enter their identity information to the APP and register on the door lock with their real names. The system transfers the status and manipulate information of locks to mobile phones through the cloud by the Wi-Fi module in real-time, realizing the remote monitoring of the house security system.
