Intelligent sprinkler capable of sensing change of moisture content in plants of lawn

Abstract

The invention discloses an intelligent sprinkler capable of sensing change of moisture content in plants of a lawn. The intelligent sprinkler capable of sensing change of the moisture content in the plants of the lawn comprises a sensing type moisture measuring device, a controller and a sprinkler body, wherein the sensing type moisture measuring device comprises a cylindrical sensing plate, a moisture tester and a pair of microwave transmitting / receiving devices; the cylindrical sensing plate sleeves the periphery of a plant to be irrigated; a microwave generator and the microwave receiving device are mounted on the cylindrical sensing plate and positioned on the two opposite sides of the plant; the moisture tester transmits microwave through the microwave generator, and receives signalsthrough the microwave receiving device; moisture content signals of the plant are demodulated, and are transmitted to a controller; the controller receives moisture content signals, which are measuredby the sensing type moisture measuring device, of the plant to be irrigated; and the sprinkler body is controlled to accurately sprinkle the plant according to comparison between actually measured moisture content and moisture content required for the plant. The intelligent sprinkler capable of sensing change of the moisture content in the plants of the lawn is used for lawn sprinkling irrigationsystems which have landscape requirements such as a park, a residential quarter and a school, and besides improvement of efficiency and quality, water can also be saved.

Description

technical field [0001] The invention belongs to the field of gardens and relates to an irrigation device, in particular to an intelligent spraying device that senses changes in water content in lawn plants. Background technique [0002] At present, in the field of lawn spraying devices, it is gradually becoming more and more intelligent. From the initial manual watering, it has evolved into machine irrigation. Although the automatic spraying system is used, most of the control watering time is in the morning or at night. , if there are uncontrollable factors, such as hot and dry weather, when the lawn plants need more water, the traditional automatic sprinkler cannot irrigate intelligently, and the only irrigation in the existing technology is mostly based on the measurement of soil moisture content Irrigation cannot be measured individually for each plant, and it is especially difficult to adapt to mixed plantations. In the quantitative irrigation mode, some plants will gro...

[0002] At present, in the field of lawn spraying devices, it is gradually becoming more and more intelligent. From the initial manual watering, it has evolved into machine irrigation. Although the automatic spraying system is used, most of the control watering time is in the morning or at night. , if there are uncontrollable factors, such as hot and dry weather, when the lawn plants need more water, the traditional automatic sprinkler cannot irrigate intelligently, and the only irrigation in the existing technology is mostly based on the measurement of soil moisture content Irrigation cannot be measured individually for each plant, and it is especially difficult to adapt to mixed plantations. In the quantitative irrigation mode, some plants will grow poorly or even die due to insufficient irrigation, and some dry-loving plants will suffer from excessive water. and rotten roots, so a device that can precisely irrigate individual plants is needed
