基于STM32处理器设计了一款具有自配置功能的通用物联网网关,实现了感知层传感网与数据中心服务器之间的协议转换、数据交互等功能。该网关首先通过RS485现场总线实现建筑能耗信息的采集,然后将其以XM L文件的形式存储在SD卡中,最后通过以太网的TCP协议将能耗信息上传至服务器中。实际工程项目应用结果表明,该网关能够稳定可靠地运行,满足建筑能源系统物联网对数据采集与传输的需求。

Based on the STM32 processor ,a general gateway with the self-configuration function is designed , w hich can realize data communication and conversion of different protocol interfaces between the sensor network layer and the server in data center .Firstly ,the gateway collects energy consumption data in target building through RS485 field bus .And then ,stores the data into SD card in the form of XML format .Finally ,it transmits the data to server by TCP protocol .The results of practical project reveal that the gateway is reliable and steady ,and meets the requirements of the data acquirement and data transmission of internet of building energy system .
