Satellite irrigation system controller

Abstract

The invention relates to a remote irrigation control system, more particularly to a satellite irrigation system controller with wireless control. The controller includes three parts: power, central control, and signal output. The central control part is a microprogram control unit, and an output terminal of the microprogram control unit is connected with a board address switch and a driver array. The driver array is output to a relay board through an electronic output terminal. The input port and output port of the microprogram control unit are connected with an RS485 interference as well as a real-time clock and a flash memory, and the power part provides direct-current power supply of 12V for the microprogram control unit. The satellite irrigation system controller provided in the invention has a function of directly sending a digital controlled signal to unlatch or close an electromagnetic valve for normal irrigation one by one or selectively. Therefore, pertinency for irrigation is stronger, so that the waste of precious water resource is avoided. Meanwhile, increase of manual labor and material resources brought about by cable laying can be avoided, so that the cost is substantially reduced.

Description

technical field [0001] The invention relates to a remote irrigation control system, in particular to a wireless-controlled satellite irrigation system controller. 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 intervals. Artificial irrigation is to observe 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.
