摘要
为解决家庭物联网水、电、气三表数据广域传输中低功耗、低成本的问题,设计了基于NB-IoT网络的智能网关,以STM32F103芯片为核心控制器,主要包括三表数据采集接口、NB-IoT网络接口和家庭智能终端扩展接口,实现了家庭三表数据采集及对智能云端平台的传输功能,并为智能家居服务数据提供网络支撑;所设计智能网关针对性的解决了三表数据的统一管理问题,创新性的将三表接入网关设计成86型底盒的方式,在较小改变房屋电气布局基础上实现了智能网关的安装;实验及应用测试结果表明,所设计智能网关具有性能稳定、功耗较低、便于安装的优势,可快速实现家庭物理信息系统的构建。
To solve family connected to the water,electricity,gas three table data wide-area transmission problem of low power consumption,low cost,design the intelligent gateway based on NB-IoT networks,STM32F103 chip as the core controller,mainly including three table data acquisition interface,NB-IoT network interface and home intelligent terminal extension interface,realized the family three tables of intelligent data acquisition and transmission function of the cloud platform,and provide network support for intelligent household service data.The designed intelligent gateway can solve the problem of the unity of the three table data management,the innovative designs three table access gateway type 86 bottom box,on the basis of small change building electrical layout implemented the installation of the intelligent gateway.The experimental and application test results show that the designed intelligent gateway has the advantages of stable performance,low power consumption and easy installation.
