基于RS485通信的智能门锁管理系统的设计与实现

目前,智能门锁普遍采用的Sub-1G,NB-IoT等主流组网方式,存在通信功耗高、穿透性易受天气和建筑物影响、通信时效性差、维护成本高等问题。为解决以上问题,文中设计了一种基于RS485通信的智能门锁系统,该系统采用平衡发送和差分接收方式实现通信,通过智慧物联管理平台实现门锁的管控和数据交互,其与原有数字化校园平台和各应用系统接口对接后,可实现统一身份认证和统一共享数据。

Design and Implementation of Intelligent Door Lock Management System Based on RS485 Communication

At present, Sub-1G, NB-IoT and other mainstream networking methods adopted by intelligent door locks have the problems of high communication power consumption, penetrability, poor communication timeliness and high maintenance cost. To solve the above problems, an intelligent door lock system based on RS485 communication is designed, which uses balanced transmission and differential reception to achieve communication, and achieves door lock control and data interaction through the intelligent Internet of Things management platform, after interfacing with the original digital campus platform and various application systems to achieve unified identity authentication and unified data sharing.
