Remote monitoring terminal for soil moisture content of farmland soil

Abstract

The invention provides a remote monitoring terminal for a soil moisture content of farmland soil. The remote monitoring terminal comprises a data collection unit, an MCU microprocessor, a GPS module,a wireless communication unit and a power supply unit, wherein the data collection unit comprises a soil temperature and humidity sensor and a signal conditioning circuit, and the power supply unit comprises a solar cell panel, a rectifying and voltage reducing circuit and a storage battery. By means of being combined with a sensor technology, a single chip microcomputer technology, a GPS technology and a wireless communication technology, the remote monitoring terminal disclosed by the invention can achieve the purpose of collecting soil moisture information automatically in real time in an unmanned mode and also can achieve the purpose of finishing information collection and transmission regularly in real time in the unmanned mode. The remote monitoring terminal is not affected by spaceand geographical environment, can be distributed in a large area at will and has the advantages of small volume, flexibility in movement and convenience in installation. A specific geographic positioncan be calibrated by a GPS and multipoint collected data can be sent to a mobile terminal in a GPRS wireless mode, so that remote monitoring is achieved, communication cable distribution in a large area is avoided, and cost is saved.

Description

technical field [0001] The invention relates to the technical field of Internet of Things monitoring, in particular to a remote monitoring terminal for farmland soil moisture. Background technique [0002] Soil moisture is one of the most important and commonly used soil information. It is the basis for judging the profit and loss of soil moisture, irrigation and fertilization decisions, and drainage measures during the crop growth and development period. At the same time, mastering the information of farmland soil moisture in a large area will help to better understand and master the national water resources in the area. Therefore, accurate and rapid monitoring and forecasting of soil moisture is of great significance. The traditional soil moisture monitoring is through successively using instruments and methods such as drying weighing, neutron moisture meter, TDR time domain reflectometer and ground penetrating radar. Information is collected manually. However, the coll...

Problems solved by technology

The traditional soil moisture monitoring is through successively using instruments and methods such as drying weighing, neutron moisture meter, TDR time domain reflectometer and ground penetrating radar. Manual collection of information

However, the collection of soil moisture information in large-scale farmland involves a lot of manpower and material resources, which is not conducive to information data transmission.

The use of satellite remote sensing method for soil moisture monitoring, although the long-distance collection and transmission of information can be realized, but the cost is high, and the test accuracy is easily affected by climate and terrain conditions, and the real-time performance is poor.
