Facility agriculture greenhouse environment parameter self-adaptation controlling method

Abstract

The invention provides a facility agriculture greenhouse environment parameter self-adaptation controlling method. The facility agriculture greenhouse environment parameter self-adaptation controlling method includes the following steps of achieving self-adaptation control over greenhouse environment information parameters and auxiliary facilities by the adoption of a method of combining fuzzy control, a PID control and manual control and achieving automatic conversion of control modes based on greenhouse environment information at the same time based on a greenhouse environment self-adaptation data base, by the adoption of multilevel schema conversion control, and on the basis of set value control; gradually optimizing and perfecting the greenhouse environment self-adaptation data base according to greenhouse environment real-time information, invoking information in the data base by means of a priority level automatic identification function, and finishing self-tuning of set values; and setting intermediate values by the adoption of hysteresis control method and on the basis of the set value control in order to conduct optimizing adjustment. The facility agriculture greenhouse environment parameter self-adaptation controlling method achieves the self-adaptation control of the greenhouse environment parameters, reduces motion frequency of equipment, prolongs the service life of the equipment, improves a greenhouse management mode, improves labor productivity, and has strong practical value.

Description

technical field [0001] The invention relates to the technical field of intelligent control methods, in particular to an adaptive control method for environmental parameters of a facility agricultural greenhouse. Background technique [0002] Greenhouse is an important part of facility agriculture. It is a modern agricultural production method that integrates the application of engineering equipment technology and environmental technology for crop production. It is one of the key projects of agricultural development in my country. Greenhouses can bring considerable economic benefits and greatly increase land utilization, labor productivity and product output. In the process of planting agricultural plants, the greenhouse environment is closely related to the growth, development, and energy exchange of plants. Environmental measurement and control is the guarantee for the realization of automatic and scientific greenhouse production management. Through the collection, process...

Problems solved by technology

In the past, more cumbersome methods were used for environmental control, all of which were carried out under the condition of manual intervention, which consumed a lot of manpower and material resources, and the effect was not good.

At present, with the rapid development of the national economy, the scale of the agricultural industry continues to expand, and more and more varieties of crops are cultivated in greenhouses. For a large number of greenhouses, traditional environmental control methods obviously cannot meet the development needs of facility agriculture.

[0003] At present, a variety of greenhouse intelligent control methods have been developed in China, such as the control method based on crop information fusion. This method is to establish a greenhouse intelligent control system under the evaluation index system, but it is necessary to collect crop physiological information and growth information, which is difficult to collect. , which is not conducive to promotion; another example is the segmented control method, which uses a segmented control strategy to control the output of the system, but has disadvantages such as poor anti-interference ability and too frequent equipment actions; there are also some control methods such as control based on crop economic prediction method, which is limited to theoretical research and has not been put into practical operation
