Embodiment Construction

[0022] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0023] A schematic diagram of the appearance and structure of a farmland environment monitoring device according to an embodiment of the present invention is shown in Figure 1, including:

[0024] The soil moisture sensor 1 and the soil electrical conductivity sensor 2 compounded at the end of the support rod 4 are separated by an insulating ring 3 . Among them, the soil moisture sensor 1 is composed of a metal cone and a metal ring; the soil conductivity sensor 2 is composed of four metal rings; the insulating ring 3 is made of polyvinyl chloride, namely PVC material. The moisture content and electrical conductivity information of different soil profiles can be obtained ...

Abstract

The invention discloses a farmland environment monitoring device, which comprises a soil water content sensor (1) and a soil conductivity sensor (2) combined on the tail end of a support rod (4), and an insulating ring (3) for isolating the soil water content sensor (1) from the soil conductivity sensor (2), wherein the support rod (4) has a hollow structure; the soil water content sensor (1) and the soil conductivity sensor (2) are connected with a sensor signal conditioning unit (7) through a coaxial line (5) in the support rod (4); a solar power supply (10) is used for supplying power to the device and transmitting voltage information to an information collection unit (8); and the information collection unit (8) is used for collecting signals outputted by the sensor signal conditioning unit (7), acquiring the solar intensity information according to the voltage information transmitted by the solar power supply (10) and transmitting data with a wireless transceiving module (9). By adopting the solar power supply for supplying power to the device, the invention can ensure the continuous normal operation of the device, and the wireless transceiving module can achieve long-distance data transmission.

Description

technical field [0001] The invention relates to the technical field of solar energy and data acquisition, in particular to a monitoring device for solar power supply, measurement of soil moisture content, electrical conductivity and sunshine intensity, and applied to farmland environment. Background technique [0002] The growth of crops is closely related to the farmland environment in which they live, and soil moisture content, soil electrical conductivity and sunlight intensity are important physical parameters that affect the growth of crops. With the continuous development of data acquisition technology, sensors for measuring soil moisture content and soil electrical conductivity in farmland environments have been widely used. [0003] Soil moisture content refers to the amount of water contained in a certain amount of soil, often expressed as a percentage of dry soil weight or soil volume. Water is the lifeblood to ensure the growth of crops, and it is directly relate...
