In order to ensure the accuracy, reliability and stability of data, a multi-sensor hybrid fusion technology is adopted, the detected data is optimally fused by using a Kalman filtering method according to the characteristics of sensors and sensing information, the information is extracted into typical characteristic information through an artificial neural network, and finally the sensor information is preprocessed by a Bayes probability inference method. The method ensures accuracy and credibility, the spatiotemporal property of data fusion, reduces information loss, improves the real-time property of data and ensures the systematicness of data fusion.
On one hand, the whole monitoring system can realize the adjustment of internal environment parameters so as to adapt to the environment of crop growth; on the other hand, data of the crop growth process (parameters such as the leaf area of a plant canopy, the porosity of the plant canopy, the structure of the plant canopy and the like in vegetation image information) is displayed in a visual mode in cooperation with the conditions of soil components, humidity and temperature changes, so that the growth condition of crops in the greenhouse can be better monitored and stored, and the traceability work after the crops are picked is facilitated.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
