Automatic monitoring terminal machine for soil moisture

Abstract

The invention relates to an automatic monitoring terminal machine for soil moisture, which mainly comprises a terminal box body, a solar cell panel, a GPRS transmitting antenna, a moisture circuit board, a moisture sensor, a communication circuit board, a temperature sensor, a humidity sensor, a moisture shielding circuit box, a communication shielding circuit box, a solar storage cell and a solar controller. The terminal machine is connected with the moisture sensor embedded into the soil through a shielded cable, then transmits moisture information to a moisture circuit, and transmits the moisture information to a master station computer through a communication circuit to perform informational digital processing to obtain the soil moisture condition of a certain region. The terminal machine has the advantages of advanced and reasonable design, compact structure, safety, stability, reliability, energy conservation and accurate, substantial and reliable data acquisition and transmission, can remotely and automatically monitor the soil moisture conditions of different regions and predict the moisture conditions, and is a quite ideal automatic monitoring terminal machine for the soil moisture.

Description

technical field [0001] The invention relates to a terminal machine for automatic monitoring of soil moisture, and belongs to the technical field of soil moisture monitoring equipment and applications. Background technique [0002] Soil moisture, that is, soil water content, is an important indicator that affects the growth and development of crops and the degree of regional drought. Due to the differences in regional topography, soil physical and chemical characteristics, meteorology and other factors, the distribution of regional moisture is also extremely uneven. Timely grasp the regional soil moisture The dynamic information is of great significance for improving the level of drought management, scientifically guiding drought relief, preventing and mitigating drought disasters and their losses, ensuring domestic water, ecological water, and scientific utilization of water resources. [0003] Dynamic, real-time, and continuous monitoring of soil moisture data requires adva...

Problems solved by technology

[0005] For example, the neutron meter measurement method does not need to dig soil and does not destroy the soil structure during measurement. It can be monitored continuously at fixed points, which is fast and accurate. However, when the neutron meter is used for measurement, the indoor and outdoor curves differ greatly, due to the different bulk density and soil texture of the physical properties of the soil. , will cause large curve movement, poor vertical resolution, difficult surface measurement, and the neutron meter is more expensive, the radiation hazard is greater, and it cannot be widely used

[0006] For example, the γ-ray method can quickly and accurately measure the moisture content, and has a higher vertical resolution than the neutron meter, but similar to the neutron meter, it also has safety and other problems, making it not widely used
