Electromagnetic valve for automatic irrigation

Abstract

The invention relates to an automatic control system for remote irrigation, in particular to an electromagnetic valve which is used for irrigation and capable of realizing automatic control of remote irrigation. The electromagnetic valve comprises a manual operation button and a power supply switch, and further comprises a voltage regulator, an electromagnetic valve and a microcontroller which are connected with the power supply switch; the electromagnetic valve is connected with a valve in a water pipe; and the microcontroller is connected with the voltage regulator. According to the automatic control system disclosed by the invention, an irrigation program indication can be sent to the valve in a wireless manner, so the program is unnecessarily sent in a wired mode; and only two power supply wires are needed. If the electric energy is provided by the wind energy or the solar energy, the wireless manner can be realized totally without needing the power supply wires, therefore the copper wire spreading in the conventional structure is avoided, and the manpower and resource costs are saved; meanwhile, the remote irrigation can be realized more conveniently; and the control is more automatic and intelligent.

Description

technical field [0001] The invention relates to a remote irrigation automatic control system, in particular to an irrigation electromagnetic valve capable of realizing remote irrigation automatic control. Background technique [0002] In terms of existing agriculture, in order to ensure the growth and development of crops, it is necessary to monitor the water demand of crops and perform real-time irrigation; in terms of urban landscaping, it is also necessary to frequently irrigate trees, flowers and plants. In modern agricultural irrigation technology, especially in some remote mountainous areas, a large amount of manpower, material and financial resources are required to irrigate some large-scale crops, which not only wastes limited resources, but also increases the cost of agricultural production and dampens the enthusiasm for agricultural production. In some existing irrigation methods, most of them adopt artificial irrigation and automatic irrigation at regular interval...

AI Technical Summary

Problems solved by technology

Although artificial irrigation can basically irrigate according to the water shortage of crops, its disadvantages are: it requires a lot of manpower consumption, labor intensity is high, and water resources are wasted. It is very difficult to truly realize real-time irrigation

Its disadvantages are: the irrigation is poorly targeted, and it cannot be irrigated according to the actual water demand of the crops, which may cause waste of water resources, and it is necessary to lay a two-way cable between the control valve and the control terminal, resulting in an increase in manpower and material costs.
