Wireless intelligent control system and method for alternative irrigating

Abstract

The invention relates to wireless intelligent control system and method for alternative irrigating. The system comprises a microprocessor module, a sensor module, a solenoid valve driving module, a man-computer interaction module, a wireless communication module and a power module. The system is on the basis of the essential concept of local and regional alterative irrigating of crops; a pressure flow sensor, a soil water and temperature sensor, a rainfall sensor, a leaf temperature sensor and a leaf humidity sensor and other sensors are utilized to obtain rich irrigating information, so that the intelligent crop irrigation control degree and control precision are improved. Compared with the existing irrigation technology, the system has the advantages of being high in intelligent degree, high in man-computer interaction performance, and high in automatic fault diagnosis; the system is applicable to a farmland irrigation control system using the alternative irrigating technology and can be also used for irrigating of a greenhouse; the type of the crops can be adjusted on site or remotely adjusted, so that the irrigating requirements of maize, cotton, vegetable and other crops can be met.

Description

technical field [0001] The invention relates to the technical field of surface irrigation, in particular to an intelligent method and system for controlling alternate irrigation of local root zones of crops. Background technique [0002] In 1997, based on the principle of water-saving irrigation technology and the root signal theory of crops' perception of water shortage, Kang Shaozhong proposed a root partition alternate irrigation technology, which actively controls the water status of crop root zone soil in a certain area of ​​horizontal or vertical section, Make a part of the root zone of the crop grow in a dry or relatively dry environment all the time, limit the water absorption of the root system in this part, and at the same time make the root system appear alternately in the dry area of ​​the horizontal or vertical section through artificial control, so that the root system in the dry area produces a water stress signal It is transmitted to the leaf stomata to effec...

AI Technical Summary

Problems solved by technology

[0004] The existing surface irrigation technology still has the following problems: First, the existing root zone alternate irrigation device needs to use other experimental observation data to judge the actual water content of the crop root zone, determine whether irrigation is needed and when alternate irrigation is required , seriously affects the accuracy of control, and often misses the critical period of crop water demand, resulting in reduced production; second, the existing root system alternate irrigation device is still in the manual control stage, and it is necessary to realize partial rooting of crops through mechanical or connecting rod operations. Alternate irrigation in the district, the degree of automation is low, and the intelligent control based on human-computer interaction and real-time monitoring of soil moisture has not been realized, which is time-consuming and laborious, and the response speed is slow
