Agricultural irrigation monitoring system based on Internet of Things

Abstract

The invention discloses an agricultural irrigation monitoring system based on the Internet of Things. The agricultural irrigation monitoring system based on the Internet of Things comprises multiple soil moisture content monitoring nodes distributed within a field monitoring range. Each soil moisture content monitoring node comprises multiple soil moisture content sensors which are buried underground in different levels and a soil moisture content signal processing module. The soil moisture content signal processing module sends controlling information to subordinate fine drop irrigation controlling nodes of the soil moisture content signal processing module through the Internet of Things. Each fine drop irrigation controlling node comprises a ZigBee low-power short-journey wireless communication module, a singlechip and a controlling and performing unit. The system can perform solid monitoring on soil moisture content underground roots of plants in multiple depths and a fixed network is not needed in order to achieve monitoring of fine drop irrigation work. The agricultural irrigation monitoring system based on the Internet of Things has the advantages of being rapid in spreading, strong in survivability, low in communication cost when used massively, convenient to install and maintain, especially suitable for countryside areas where signal cover is poor and the like.

Description

technical field [0001] The invention relates to an irrigation monitoring system used in the agricultural production process, in particular to an irrigation monitoring system based on the Internet of Things. [0002] Background technique [0003] Agricultural irrigation is one of the effective solutions to solve various contradictions between supply and demand caused by the increasing shortage of water resources. It can irrigate in a timely and appropriate manner according to the water demand information of crops without affecting crop yields, thereby achieving a significant reduction in agricultural production. Purpose of using water. In irrigation operations, soil moisture represented by soil moisture content is an important index for calculating water demand information. Therefore, continuous, large-scale and accurate monitoring of soil moisture including soil moisture content is of great significance in fine irrigation and rational utilization of water resources. Howev...

AI Technical Summary

Problems solved by technology

However, the existing irrigation measurement and control system still has the following problems in practical application: the measurement of soil moisture content at the measurement point is generally limited to a single depth below the surface, and there is no three-dimensional monitoring of the soil moisture content at multiple depths of plant roots below the surface at the measurement point , cannot completely and accurately reflect the soil moisture in the monitoring area; the source of soil moisture content information is single, and is easily affected by external accidental factors. irrigation control

Soil water demand information and drip irrigation start and stop control signals are transmitted through wireless services such as WIFI, which rely heavily on fixed communication networks. When used on a large scale, communication costs are high, and installation and maintenance are inconvenient, especially when the signal coverage is poor. in rural areas where the system is unstable
