Communication system and method for agricultural Internet of Things wireless networking

Abstract

The invention discloses a communication system and method for agricultural Internet of Things wireless networking. The communication system for agricultural Internet of Things wireless networking comprises terminal nodes, gateway nodes and a cloud platform, wherein the terminal node is used for acquiring data information related to agriculture and sending the acquired data information to the gateway node; the gateway node is in communication connection with a plurality of terminal nodes and is used for receiving data information sent by the terminal nodes and sending the data information to the cloud platform; and the cloud platform is in communication connection with the plurality of gateway nodes and is used for receiving the data information sent by the gateway nodes and storing the received data information. Bidirectional communication can be carried out between the terminal node and the gateway node, bidirectional communication can be carried out between the gateway node and the cloud platform, data acquired by the terminal can be accurately and timely transmitted to the cloud, and agricultural workers can conveniently and remotely acquire agricultural information.

Description

technical field [0001] The invention relates to the field of agricultural information technology, in particular to a communication system and method for wireless networking of the agricultural internet of things. Background technique [0002] The construction of the agricultural Internet of Things has practical significance for the accurate, timely and rapid collection of field information and the reduction of human input in the agricultural production process. The Agricultural Internet of Things has become a research and development hotspot, but due to the particularity of the agricultural environment, especially the relative scarcity of network resources, the development of the Agricultural Internet of Things is limited. The current agricultural Internet of Things still has a series of problems such as unreasonable structure, small scale, inconvenient management, and low communication efficiency.

The Agricultural Internet of Things has become a hot spot in research and development, but due to the particularity of the agricultural environment, especially the relative scarcity of network resources, the development of the Agricultural Internet of Things is limited

The current agricultural Internet of Things still has a series of problems such as unreasonable structure, small scale, inconvenient management, and low communication efficiency.

In terms of architecture design, the current agricultural Internet of Things mostly uses small-scale networking and management and control, which cannot form a good connection with the cloud, which is not conducive to large-scale use and management, and is also not conducive to the storage and utilization of massive data; In terms of selection, Zigbee, Lora, GPRS and other methods are mostly used. Although they meet the requirements of low power consumption, they have limitations in distance or data transmission speed, low real-time performance, and slow speed; in terms of communication protocols, although there are MQTT, Lightweight IoT protocols such as CoAP are available, but when used, there are still situations where flexibility is low or inapplicable
