Forest soil parameter measuring device and method

Abstract

The invention provides a forest soil parameter measuring device and method. The device comprises a soil moisture detecting module, a soil conductivity detecting module, a soil temperature detecting module, a power source, a power control module, a clock module and a processor. Each one of the soil moisture detecting module and the soil conductivity detecting module comprises a probe. The soil temperature detecting module and the probe are installed on an installation body. The clock module is connected to the processor and provides a clock signal to the processor. The processor is connected tothe power control module. According to the clock signal, a control signal is output to the power control module. The power source is respectively connected to the three detection modules. The power control module is connected to the power source. According to the control signal, powder is output to the soil moisture detecting module and the soil temperature detecting module or is output to the soil conductivity detecting module and the soil temperature detecting module. The probes realize time division multiplex access so that the mutual influence between the various functional modules is avoided during measurement and the detection accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of measurement, and more specifically, to a device and method for measuring forest soil parameters. Background technique [0002] Soil is an important part of the forest ecosystem, which has positive significance for the huge ecological and environmental effects of the forest, and is an important basis for the development of precision agriculture and forestry practices. Soil moisture, temperature and electrical conductivity are important parameters of soil that play an important role in the growth of crops. [0003] Forest soil moisture is the carrier and solvent for the operation of forest plant nutrients, the regulator of aeration and the diluent of toxic substances in the soil, and it is also the source of soil runoff. The physical properties of soil moisture are often used as an important indicator for evaluating soil quality, which not only determines the water, air, heat and biological conditions in t...

Problems solved by technology

[0007] First of all, when using multiple sensors to measure, it is difficult to ensure that different sensors are in the same space when measuring the same soil, but the soil properties determine that the soil has spatial irregularities, and the differences in the soil itself in different spaces will lead to the disadvantages of large measurement errors and low accuracy of multiple sensors , In addition, the measurement of moisture content, temperature and conductivity of soil by multiple sensors is likely to cause mutual interference, and the accuracy is difficult to guarantee. For example, the holes left after the measurement of the previous sensor will interfere with the measurement of the next sensor. Finally, non-integrated The multiple sensors of the traditional style are inconvenient to carry and operate, and the cost is also high
