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...

Problems solved by technology

Smart gateways have been studied in the fields of smart home, heat pipe network system, and water tank control; some scholars have proposed the design method of the agricultural Internet of Things system, but they have not mentioned the design of smart gateways. Some scholars have proposed a system based on Android The system’s intelligent gateway design for greenhouse heterogeneous network environment monitoring has initially realized greenhouse environment monitoring, but no detailed agricultural data packaging standards have been proposed; some scholars have designed a ZigBee / 3G-based Internet of Things network management system for water tanks. Temperature monitoring, but there are certain limitations in application; some scholars have proposed a configurable wireless sensor network WSN (wireless sensor network) gateway architecture ReGA (Re-configurable Gateway Architecture) based on WinCE system, which can realize on-site Comprehensive management of visualized equipment and monitoring, but its design platform is not suitable for applications in other open source systems such as Linux

[0003] The intelligent gateway has made some progress in the research of the agricultural Internet of Things, but there are also deficiencies, mainly reflected in the fact that the agricultural Internet of Things involves many technologies, a wide range of data, inconsistent data packaging formats, and inconsistent communication protocols. Most agricultural Internet of Things systems use their own definitions The lack of a unified communication standard for intelligent gateways makes it difficult to meet the technical requirements for large-scale promotion of the agricultural Internet of Things, and it does not meet the current development requirements of agricultural big data and precision agriculture
