Internet of things-based saline and alkaline land improvement information acquisition system

Abstract

The invention relates to the technical field of saline and alkaline land improvement, in particular to an Internet of things-based saline and alkaline land improvement information acquisition system. The Internet of things-based saline and alkaline land improvement information acquisition system comprises at least three data acquisition nodes, wherein each data acquisition node can be used as a monitoring object and also can automatically transfer data information transmitted by other data acquisition nodes; each data acquisition node can be further wirelessly connected with a plurality of isolated data acquisition nodes which do not take network information transferring tasks within a range covered by a signal of the data acquisition node; the problems of unsmooth transmission of acquired information and easy loss of data due to low outdoor network coverage effect are solved; the Internet of things-based saline and alkaline land improvement information acquisition system is particularly suitable for acquisition of large-area and multi-plot information, so that waste of water resources due to failure of a monitoring system can be avoided; meanwhile, the data acquisition nodes, a data coupler and a data transmitter are provided with protective structures; after the data acquisition nodes, the data coupler and the data transmitter are arranged in soil at an acquisition point, damage to electrical elements due to salt and alkali can be prevented, and the service life can be prolonged.

Description

technical field [0001] The invention relates to the technical field of saline-alkali land improvement, in particular to an information collection system for saline-alkali land improvement based on the Internet of Things. Background technique [0002] In some western cities in China, the area of ​​salinized soil is relatively large, and there are many types of salt composition. Among the existing cultivated land, the area affected by different degrees of salinization accounts for a large proportion of the total cultivated land area. It is necessary to carry out these agricultural water and soil Irrigation is used to solve the problem of poor water and soil, especially the current situation of irrigation but no drainage in the Hetao area of ​​Inner Mongolia. At present, the drainage system in China mainly includes open ditch drainage system, concealed pipe drainage system and shaft drainage system.

[0002] In some western cities in China, the area of ​​salinized soil is relatively large, and there are many types of salt composition. Among the existing cultivated land, the area affected by different degrees of salinization accounts for a large proportion of the total cultivated land area. It is necessary to carry out these agricultural water and soil Irrigation is used to solve the problem of poor water and soil, especially the current situation of irrigation but no drainage in the Hetao area of ​​Inner Mongolia. At present, the drainage system in China mainly includes open ditch drainage system, concealed pipe drainage system and shaft drainage system. The traditional drainage system is in the case of bare land. Flood irrigation is carried out on the field to make the soil water saturated, and then the soil salt dissolves into the water to form saturated infiltration and drains into the drainage ditch, so as to achieve the purpose of salt drainage. This type of drainage can effectively remove the salinity of the soil, but it has many disadvantages , the degree of intelligence is low, manual inspection is required during irrigation, and a large amount of human and financial resources are wasted by manual control of the irrigation system. In addition, an optimized irrigation scheme cannot be formed, resulting in a large waste of resources. In addition, the control system in the prior art needs to consume a large amount of grid power. , and some salt control systems in the prior art use wired transmission, and the wiring is complicated. In areas with harsh environments, the lines are easily damaged, resulting in failure of the monitoring system. However, the existing wireless transmission monitoring system has poor network coverage in the field, resulting in the collection of information transmission. Unsmooth, data is easily lost, and the collection of large-area and multi-plot information cannot be synchronized, which greatly limits the analysis of water and salt information in saline-alkali land. In addition, the unique environment of saline-alkali land makes the sensor susceptible to corrosion
