Greenhouse automatic control method and system based on complex event processing

Abstract

The embodiment of the invention provides a greenhouse automatic control method and system based on complex event processing, and the method comprises the steps: obtaining the environment information of a greenhouse, and determining an atomic event based on the environment information; inputting the atomic event into a complex event processing engine, and determining control information output by the complex event processing engine; and controlling a greenhouse controller in the greenhouse based on the control information. A complex event processing engine is introduced, the problems that greenhouse data are numerous, the coupling degree between controls is high, the cohesion degree is low, and a universal complex event aggregation structure is difficult to form are solved, a greenhouse controller in a greenhouse is controlled through control information output by the complex event processing engine, the control precision is higher, and the effect is better. Moreover, a complex event processing engine of a time automaton and an RAPIDE language is utilized, an event relationship existing in the greenhouse is analyzed through a greenhouse information transmission model, and the type and characteristics of greenhouse data are combined, so the method can be suitable for most agricultural control scenes.

Description

technical field [0001] The present invention relates to the technical field of automatic control, and more particularly, relates to a greenhouse automatic control method and system based on complex event processing. Background technique [0002] At present, in order to realize the cultivation or seedling cultivation of temperature-loving vegetables, flowers, forest trees and other plants in low-temperature seasons in seasons that are not suitable for plant growth, greenhouses are indispensable facilities. To reduce the workload of the staff, automatic control of the greenhouse is essential. [0003] The existing greenhouse automatic control methods usually include: threshold control, decoupling control, control through neural network and control through expert system. Among them, the threshold control directly acts on the control by setting the trigger threshold, which is simple and easy to use, but does not consider the coupling, hysteresis and inertia of the greenhouse, a...
