Research on Intelligent Irrigation and Fertilization System In Greenhouse Based on Cloud Computing

Abstract

In view of our country of precision fertilization device mainly depend on import, automatic fertilizing device and the actual market needs a serious gap between the status quo, this paper combines the PAC technology, proposed the classic model of agricultural water and fertilizer management, controlled by the central, lower computer, actuator, sensor is composed of four parts, the classic model makes full use of the advantages of PAC technology, such as the identification of general-purpose programming language, PC machine hardware and software resources are rich, flexible communication mode, can use the rich information resources management. In this paper, by using this model, the design and implementation of three systems, one is the automatic control system of deep liquid cultivation, two is the small size intelligent drip irrigation system, three is a multi-threaded irrigation thought realizes the construction of agricultural information Park medium scale, through continuous improvement and perfection, successfully extended to a PC corresponding to a plurality of slave machine, formed from the structure. Through the test of practice, the system of flexible assembly, strong expansibility, low cost, easy popularization, out of a road of independent innovation, has made an attempt and efforts for national agricultural informatization.
