摘要
提出一种基于Modbus通信协议的通用物联网网关。网关以STM32F429和ESP8266为核心,可以使用物联网网关的RS485接口获取Modbus RTU总线数据,通过MQTT协议将数据上传到阿里云物联网平台,用户可使用PC网页或智能手机APP等方式实时查看设备运行情况,以大棚温湿度测量设备的远程监测为例,为使用Modbus RTU总线设备的运行监测系统提供了通用且有效的解决途径。
In the paper,a universal internet of things gateway based on Modbus communication protocol is proposed.Taking the gateway STM32F429 and ESP8266 as the core,the system can use the internet gateway RS485 interface to get the Modbus RTU bus data,through the MQTT protocol to upload data to Ali cloud internet of things platform,users can use the PC web page or a smart phone APP methods such as real-time view the running status of equipment,greenhouse temperature and humidity remote monitoring of the measuring device,for example,for a variety of using Modbus RTU bus equipment operation monitoring provides a general and effective solution.
