摘要
文章对农业物联网仿真系统进行了介绍。在说明了农业物联网仿真系统结构组成的基础上,对网关的结构和集中显示以及远程控制的功能进行了描述;阐述了网关与子站通信的Modbus通讯协议的报文结构和应用;在基于Modbus协议的基础上,实现了网关与感知层仿真设备的通信。
This article introduces the simulation system of agricultural internet of things.On the basis of explaining the structure of the agricultural internet of things simulation system,the structure and centralized display and remote control functions of the gateway are described;the message structure and application of the Modbus communication protocol for the communication between the gateway and the substation are described.Based on the Modbus protocol,the communication between the gateway and the perceptual layer simulation device is realized.
