Farmland environment wireless sensor network monitoring system and wireless transmission method thereof

Abstract

The invention belongs to the technical field of agricultural internet of things, and discloses a farmland environment wireless sensor network monitoring system and a wireless transmission method thereof. The system comprises a data acquisition module, a data transmission module and a control center, wherein the data acquisition module comprises a plurality of data acquisition nodes and corresponding data reading single-chip microcomputers, and the data transmission module is a LoRa module; each data acquisition node is placed on the surface of farmland soil to be monitored, and each data reading single-chip microcomputer is connected with the LoRa module through a Dupont line; the LoRa module transmits the soil temperature and humidity information and the PH value information to the control center in a wireless transmission mode. The wireless transmission method adopts a slave active uploading and host polling mode. The environmental information of a wide-area farm in a large range canbe accurately monitored, effective transmission of a large amount of sensor node data is realized, and the problem of low data transmission reliability of the existing network monitoring system is solved.

Description

technical field [0001] The present invention relates to the technical field of agricultural internet of things, in particular to a farmland environment wireless sensor network monitoring system and a wireless transmission method thereof. Background technique [0002] With the application of emerging technologies such as the Internet of Things and artificial intelligence in agricultural production, the appearance of agricultural production in my country is changing. The connotation of the Agricultural Internet of Things is to facilitate intelligent management and scientific decision-making in agricultural production under the application of emerging technologies. Digital display can achieve the goal of increasing crop yield, optimizing the quality of agricultural products, and improving farmers' income. [0003] Agricultural IoT can be divided into three layers: perception layer, transport layer, and application layer. The perception layer uses various sensors to collect vari...
