Automatic irrigation system

Abstract

The invention discloses an automatic irrigation system, comprising a main control device, an electromagnetically operated valve and a sensing device, wherein the main control device controls the electromagnetically operated valve and the sensing device through two modes of a radio way and a wired way. The inventive wired automatic irrigation system can be applied for irrigation of small area e.g. a garden, and the radio group control automatic irrigation system can be applied for irrigation of large area e.g. the field, thereby greatly reducing manual manipulation, which is of manual manipulation and greatly saves water source.

Description

technical field [0001] The invention relates to an automatic control system, in particular to an automatic irrigation system applied in agriculture or gardening. Background technique [0002] The planting of plants needs to keep a certain humidity and moisture in the soil in which it is planted, which requires people to water the plants frequently. The amount of watering to plants is affected by time and geographical location. If the plants are not properly irrigated in time, the growth of the plants will be adversely affected, and even the plants will wither due to lack of water. For example, if the family plants flowers, if the flowers cannot be watered in time to replenish water, the flowering period or the overall appearance of the flowers will be affected, and the growth of the flowers will also be affected if the water is too much. At present, the main irrigation systems in my country mainly include the following types: [0003] 1. Timing irrigation system: Most of t...

AI Technical Summary

Problems solved by technology

The disadvantage of this system is that it is not possible to adjust the irrigation time according to the season and weather. Whether it is drought or sufficient rain, it will irrigate according to the set time and irrigation amount, which not only affects the growth of plants, but also causes great damage. of water waste

Not suitable for water-scarce areas

[0004] 2. Timely irrigation system: The irrigation system can control the irrigation system to irrigate according to the detected local soil moisture content. However, due to the great differences in the soil in various places and the low precision of the instrument, the detection results will be inconsistent. Larger errors, resulting in misfilling

If you use precision instruments imported from foreign countries, although it can improve the accuracy of detection and reduce the false irrigation rate, the price of the instrument is expensive, and the price of a humidity tester with a certain accuracy is more than 1,000 US dollars, and its operation process is manual. And it is extremely complicated, which will greatly increase the product cost

[0005] 3. Traditional irrigation system: This system uses AC power supply, and all its controls are done manually, and the irrigation effect is not good; when this system is used, it needs to set up a power grid in the field, which not only increases the cost of use, but also increases the difficulty of installation

Then the system causes a lot of waste of resources when it is installed and used, which greatly reduces its practicability
