Intelligent Security System Based on LoRa Technology and Its Implementation

本文以物联网时代智能安防需求为出发点,基于LoRa技术和Renesas公司的RL78/G12系列低功耗微处理器,设计实现了一套多功能安防系统。该系统集成了气体检测传感器、温湿度传感器、电压检测和进出检测等模块。此外,本文还设计了一种终端与云端之间的数据传输协议。通过该协议,终端节点将采集到的数据上传至云端处理,用户也可以在云端对终端节点进行集中管理和远程配置。同时本文提出的系统软件采用了模块化设计,可在云端对终端设备进行个性化配置,从而使终端适应不同安防需求的场景以及达到良好的功耗控制,最终实现一种低功耗、广覆盖的智能安防管理系统。

Based on LoRa technology and Renesas RL78/G12 series low power microprocessors,this paper designs and implements a multifunctional security system.The system integrates gas detection sensor,temperature and humidity sensor,voltage detection and in-out detection modules.In addition,this paper also designs a data transmission protocol between the terminal and the cloud.Through this protocol,the terminal node uploads the collected data to the cloud for processing.Users can also centralize the management and remote configuration of the terminal node in the cloud.At the same time,the system software which proposed in this paper adopts modular design can configure the terminal equipment individually in the cloud,so that the terminal can adapt to different security needs and achieve good power control,and finally achieve a low-power,wide-coverage intelligent security management system.
