Water-fertilizer integrated intelligent accurate control system and control method thereof

Abstract

The invention discloses a water-fertilizer integrated intelligent accurate control system and a control method thereof, and relates to water-fertilizer control systems in cross application of related information technology, agricultural irrigation and scientific fertilizing technology. The system consists of a monitor (100), a serial conversion module (200), a lower computer (300), an actuating mechanism (400) and a rotation irrigation district (500), which are connected in turn. In the method, water-fertilizer integrated accurate decision control software is mainly operated; the monitor sends a control command through the serial conversion module; the lower computer receives the control command through a shield cable and converts the control command into a logic control sequence; and the actuating mechanism acts according to the logic control sequence in turn to complete watering and fertilization of the rotation irrigation district. The invention is low in cost and high in expansibility and practicability, reflects the development trend of 'accurate irrigation and accurate fertilization', and has practical value for relieving water resource contradiction of China, reducing agricultural non-point pollution and ensuring food security of China.

Description

technical field [0001] The invention relates to a water and fertilizer control system for cross-application of related information technology, agricultural irrigation and scientific fertilization technology, in particular to an economical and practical integrated intelligent and precise control system of water and fertilizer and its control method. Background technique [0002] In the 1930s, France began to explore the automatic control technology of irrigation and fertilization; since the 1950s, developed countries such as the United States and Japan have applied electronic technology, sensor technology, and computer science and technology to agricultural irrigation and drainage networks, and have been widely developed and used. , The control method has gradually developed from on-site control to wireless control, and the control mode has developed from decentralized control to centralized control. [0003] Many projects in our country have introduced some foreign automatic...

Problems solved by technology

However, most of the research focuses on academic and technology introduction. Considering that the characteristics of water and fertilizer requirements of crops are not sufficient, the system construction cost is expensive, and the practicability is not strong. Therefore, it is necessary to integrate the existing mature technologies of multiple disciplines to develop an economical and practical water and fertilizer integrated system.
