Salinized soil monitoring and early warning system and method based on Internet of Things

Abstract

The invention discloses a salinized soil monitoring and early warning system and method based on Internet of Things. The salinized soil monitoring and early warning system comprises measurement terminals and a monitoring center, wherein the measurement terminals are used for detecting moisture content, temperature and conductivity of soil in the zone to be detected, generating measurement data and sending the measurement data to the monitoring center through Internet of Things; the monitoring center determines status-quo distribution of soil salinity according to the received measurement data and performs visual display through a display screen. By means of the salinized soil monitoring and early warning system and method, in-situ test on soil properties is performed through the measurement terminals arranged on all monitoring points, the soil properties are sent to the remote monitoring center through the wireless network, storage, analysis and release of the measurement data are achieved, and status quo evaluation on the soil salinity and analysis early warning of the variation trend of the soil salinity in the zone to be detected are achieved. Therefore, the salinized soil monitoring and early warning system and method based on Internet of Things has important significance in effective utilization and management of coastal reserved land resources.

Description

technical field [0001] The invention belongs to the technical field of soil detection, and in particular relates to an automatic monitoring and early warning system and method for detecting soil properties, especially soil salt content. Background technique [0002] As one of the five major soil problems that plague human beings, saline soil is widely distributed around the world. According to different geographical locations, it is divided into inland saline soil and coastal saline soil. Due to the characteristics of its geographical location, the coastal saline soil has shallow groundwater burial depth, large evaporation and frequent tide backflow, resulting in drastic changes in water and salinity. Therefore, the establishment of an automatic monitoring system for saline soil is essential for reasonable management. Land resources play an important role. [0003] At present, the monitoring and research work of saline soil has been carried out for a long time, mainly inclu...

Problems solved by technology

These methods have their own advantages and disadvantages. For example, although the direct measurement method is simple and accurate, it is time-consuming and labor-intensive; although the remote sensing image method is highly automated, it requires a wealth of basic data; It is widely used in the monitoring field of saline soil because of the ease of obtaining data, but because the electrical properties of soil are easily affected by factors such as temperature and moisture content, when using electrical methods for soil monitoring, it is necessary to comprehensively consider various factors. The influence of electrical properties

Although various monitoring methods and technologies are relatively mature, most of them are regular sampling or monitoring at present, and there is a lack of a monitoring platform and monitoring method that can remotely and in-situ monitor soil parameters and comprehensively analyze and early warning saline soil disasters
