Design method of agricultural internet of things intelligent gateway

Abstract

The invention provides a design method of an agricultural internet of things intelligent gateway. According to the method, a wireless sensor network is constructed by adopting the Zigbee technology, the network is divided into a sensing layer, a network layer, an information processing layer and a comprehensive application, the wireless network is implemented by a node terminal and a coordinator arranged on the sensing layer, a communication protocol is designed to complete the transmission and processing of data, the designed communication protocol is composed of an application layer communication protocol, a serial port communication protocol and a node communication protocol, the application layer communication protocol and the serial port communication protocol are converted through agateway service program, and the node communication protocol implements the package of wireless network data.

Description

technical field [0001] The present invention relates to the field of the agricultural Internet of Things, and more specifically, to a design method for an intelligent gateway of the Agricultural Internet of Things. Background technique [0002] The research on the Internet of Things technology in agriculture has attracted more and more scholars' attention. Among them, the intelligent gateway is a key technology in the agricultural Internet of Things system, which undertakes the collection, packaging and transmission of data. At present, the data packaging of the intelligent gateway of the Agricultural Internet of Things Standards and communication standards are not uniform, and there is very little research on agricultural IoT smart gateways. Intelligent gateway refers to a kind of equipment and technology that can collect, analyze, package and forward data and information. The United States and Japan have industrialized applications in the field of precision agriculture, t...
