Problems solved by technology

Hand-held devices in the prior art are relatively light, and it is not easy to be completely perpendicular to the ground plane during the process of being inserted into the soil
Moreover, the handheld device is operated by human hands, which is prone to vibration, shaking, etc., which will have a negative impact on the accuracy and precision of the measurement.
[0003] At present, there are similar handheld products in the international and domestic markets, but their functions are single, and they are limited to measuring soil moisture or salinity or temperature, and their measurement results are restricted by multiple factors: 1) The measurement depth is limited, and generally it can only measure The depth of 5-15cm; for the measurement of the root system of crops that requires a deeper depth, such as 30-40cm, it cannot be satisfied; a punching tool is required, but the punching tool cannot guarantee that the punched holes are vertically downward
2) The accuracy of measuring the depth is not controlled, and the randomness is large
3) During the measurement process, the human jitter and other errors introduced to the measurement results cannot be effectively eliminated
4) The temperature parameters at the same depth cannot be measured at the same time, so the error of temperature on moisture, salinity measurement and other temperature sensitive parameters cannot be eliminated
5) The measurement results need to be imported in the office and uploaded to the relevant decision-making agencies later, and the real-time and accuracy cannot meet the requirements
Handheld multi-parameter (moisture, temperature, salinity) soil measurement equipment has not yet been seen

Abstract

The invention relates to a handheld soil parameter measurement device. The device comprises a columnar body inserted into soil and a salinity sensor mounted on the columnar body for measuring the soil salinity, a temperature sensor used for measuring the temperature of the soil, a moisture sensor used for measuring the moisture of the soil, a displacement sensor used for measuring the implanted depth of the device, a multi-shaft movement sensing sensor used for measuring a vibrating state and a shaking state of the device, a data processing module and a power supply module, wherein the data processing module is connected with each sensor and is used for collecting and processing the soil salinity, the temperature, the moisture, the implanted depth, the vibrating state and the shaking state; and the power supply module is connected with the data processing module and is used for power supplying. In addition, the invention further provides a method for measuring the soil parameters by the corresponding handheld soil parameter measurement device. The handheld soil parameter measurement device and method provide automatic identification and correction ways for the soil measurement, so that the precision and accuracy of the soil parameter measurement can be improved.

Description

Technical field [0001] The invention relates to the technical field of agricultural production equipment, in particular to a handheld soil parameter measuring device and a soil parameter measuring method with automatic identification and error correction functions. Background technique [0002] When measuring soil parameters, the probe of the device generally needs to be inserted vertically into the soil. Because most of the soil parameters are related to its water content, and due to the influence of the earth's gravity, the distribution of water is unevenly distributed along the direction of gravity. The hand-held device in the prior art is relatively light, and it is not easy to be completely perpendicular to the ground plane when it is inserted into the soil. Moreover, the handheld device is operated by human hands, which is very easy to produce vibration, shaking, etc., which will have a negative impact on the accuracy and precision of the measurement. [0003] At present, t...
