Wireless electromagnetic valve

Abstract

The invention relates to the technical field of agriculture or forestry irrigation, in particular to a wireless electromagnetic valve capable of realizing automatic irrigation by controlling opening and closing of the wireless electromagnetic valve through a wireless transmission manner. The wireless electromagnetic valve comprises a valve coil and a power supply switch which is connected to the valve coil, and further comprises a wireless transmission module used for receiving instructions transmitted by a central controller and a data acquisition system in a same area of the valve and feeding back state information of the wireless electromagnetic valve to the central controller; and the wireless electromagnetic valve further comprises a program microcontroller used for decoding data of the wireless transmission module, received according to an SPI (Serial Peripheral interface) protocol, and comparing instruction addresses with a valve address as well as opening the electromagnetic valve to carry out irrigation. According to the wireless electromagnetic valve disclosed by the invention, an irrigation program instruction can be transmitted to the valve wirelessly, the power is supplied to the valve by only needing a power line or by converting wind power or solar power into electric energy, a wireless manner is totally realized, copper lines in a conventional structure are avoided, and costs of manpower and material resources are saved.

Description

technical field [0001] The invention relates to the technical field of agricultural or forestry irrigation, in particular to a wireless electromagnetic valve which can be controlled on and off through wireless transmission to realize automatic irrigation. 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 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 an...

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.
