Integrated adjustable automatic soil longitudinal water recording instrument

Abstract

The invention discloses an integrated adjustable automatic soil longitudinal water recording instrument which comprises a sealing shell, wherein an electronic element and a measuring assembly are arranged in the shell; the electronic element comprises a communication interface, a power supply and a mainboard; the mainboard comprises a controller and a storing device; the measuring assembly comprises an installation framework; a plurality of pairs of electrodes are arranged on the installation framework; the electrodes can slide along the installation framework; a limiting device is also arranged on the installation framework; each pair of electrodes is in data connection with the mainboard by a flexible cable; data output by the electrodes are transferred into the controller; the controller transfers the data into the storing device for storing; the power supply is used for powering the electronic element; the communication interface is connected with the controller. According to the instrument, an integrated design is adopted, the power supply, the mainboard and the communication part are packaged in the shell; the data can be recorded and stored for a long time; meanwhile, the measuring depths of different soil layers can be adjusted according to needs, so that the monitoring requirements of users on water at the different soil layers can be met.

Description

Technical field [0001] The invention belongs to the technical field of soil moisture measurement devices, and specifically relates to an automatic soil moisture recorder. Background technique [0002] Soil moisture is the water that exists in soil voids or adsorbed on soil particles. It is distributed in the soil layer from below the ground surface to above the diving surface. It is an important material component of the soil and an important factor affecting soil fertility. It is a plant and soil microorganism. Important material basis and ecological environment factors for growth and development. Soil moisture is a key link in the natural conveyor belt chain of water cycle in the earth environment, an important carrier of material circulation and energy transfer in the earth environment, and an important part of natural water resources. The composition and quantity of soil moisture are closely related to the physical, chemical and biological properties of the soil and its ...

Problems solved by technology

We know that the moisture content of soil varies greatly at different depths, and the soil moisture measuring device in the above-mentioned patent is to bury the measuring device in a certain depth for measurement, so it can only measure the moisture content value at a fixed depth at a time. When it is necessary to measure the soil moisture content at different depths, multiple multi-point buried measurements are required, which is inefficient and cumbersome.

In addition, due to the need for data collection, most of the current soil moisture measurement devices have a communication main board and are powered by solar cells. The communication main board is connected to an external antenna and other communication equipment for real-time data transmission. All are susceptible to environmental impact or man-made damage, which leads to a substantial increase in maintenance costs; and because the existing soil moisture measurement device does not store data, when the power transmission function is destroyed, it is easy to cause serious consequences of data loss
