Technical Field

The invention relates to the field of agricultural seedling culture, in particular to an automatic control system for greenhouse illumination.

Background

The intelligent seedling culture of the vegetables has the advantages of large scale, labor and cost saving, good benefit and the like, can provide important guarantee for the aspects of introducing, testing, demonstrating, popularizing excellent and new varieties, improving the breeding rate and the like, can also save land resources, ensures the seedling quality, and has huge development prospect.

At present, the method of raising seedlings in a greenhouse is generally adopted. However, the vegetables can not be sufficiently illuminated during growth, and during seedling raising in a greenhouse, illumination of sunlight is required, and illumination of light is required after the sun falls off a mountain, so that continuous photosynthesis of crops is guaranteed, and the growth of the crops is accelerated. The illumination condition in the greenhouse directly influences the growth, development, yield and quality of the vegetables.

In order to automatically control the illumination in the greenhouse, chinese patent publication No. CN106386208A discloses a light supplement control system for a photovoltaic greenhouse based on a PLC controller, wherein a light intensity sensor is arranged in the photovoltaic greenhouse, and the light intensity sensor monitors the illumination intensity in the photovoltaic greenhouse and sends the monitored data to the PLC controller; the PLC compares the preset illumination intensity data with the collected illumination intensity data in the human-computer interface, and determines the number of the LED vegetable growth lamps to be turned on according to the difference value between the actual illumination intensity data and the set value, so that the light intensity control is realized.

According to the scheme, the control of the illumination intensity in the photovoltaic greenhouse is automatically realized, however, the adjustment of the illumination intensity is carried out according to the preset conditions, and the adjustment of the illumination intensity cannot automatically adapt to the growth cycle of vegetables. If the illumination intensity is lower than the current requirement of the vegetables, the growth of the vegetables is easily slowed down; if the illumination intensity is higher than the current demand of the vegetables, energy waste is easily caused, and the vegetables can be sunburned.

Therefore, a control system capable of automatically adjusting the light intensity according to the growth cycle of vegetables is required.

Disclosure of Invention

The invention provides an automatic greenhouse illumination control system which can automatically adjust illumination intensity according to the growth cycle of vegetables.

In order to solve the technical problem, the present application provides the following technical solutions:

an automatic greenhouse illumination control system comprises an illumination module for providing artificial illumination and an illumination acquisition module for acquiring illumination intensity data; the device also comprises a control module and an image acquisition module; the image acquisition module is used for acquiring an image of a crop; the control module is used for acquiring illumination intensity data and an image of a crop; the control module calculates the current growth period of the crops based on the images of the crops, and the crop growth period and illumination intensity demand data are prestored in the control module; the control module calculates the current illumination intensity requirement based on the current growth period, the crop growth period and the illumination intensity requirement data; the control module is also used for adjusting the illumination intensity of the illumination module according to the current illumination intensity requirement.

The basic scheme principle and the beneficial effects are as follows:

because the shape of the crop changes in the growing process, the current growing period of the crop can be calculated through the image of the crop, and then the current illumination intensity requirement can be calculated based on the current growing period, the crop growing period and the illumination intensity requirement data; and adjusting the illumination intensity according to the current illumination intensity requirement. The current illumination intensity can be adapted to the growth period of crops. The scheme automatically adjusts the illumination intensity according to the illumination intensity and the illumination requirement of the crop growth period, improves the intelligent degree of the greenhouse control system, and simultaneously improves the production efficiency of the greenhouse.

Because the area of the leaves can be changed in the growing process of the crops, the current growth period of the crops can be accurately judged according to the area of the leaves.

Furthermore, the image acquisition module comprises a plurality of cameras, each area at least corresponds to one camera, and the cameras are used for acquiring images of crops in the corresponding areas.

Because when the crops are planted in the greenhouse, the planting area is large, after the crops are artificially divided into small areas convenient to manage, each area at least corresponds to one camera, and the images of the crops in each area can be collected.

Furthermore, the illumination module comprises a plurality of ultraviolet irradiation lamps, each area at least corresponds to one ultraviolet irradiation lamp, and the ultraviolet irradiation lamps are fixed on the top of the greenhouse.

When crops are planted in the greenhouse, the planting area is large, after the crops are artificially divided into small areas convenient to manage, each area at least corresponds to ultraviolet irradiation and the like, and the crops in each area can receive illumination.

The illumination intensity of each area is independently managed, the pertinence is stronger, and the growth of crops is facilitated.

Furthermore, the control module also comprises a reminding unit; the processing unit is further used for calculating the current average growth cycle according to the current growth cycles of the crops in all the areas, judging the cycle difference between the current growth cycle of the crops in each area and the current average growth cycle, and if the cycle difference of any area is larger than a preset threshold value, sending a reminding instruction to the reminding unit; the reminding unit is used for sending out a reminder.

Because the growth of crops is not only influenced by illumination intensity, but also influenced by factors such as nutrition, temperature and humidity, if the period difference of any region is greater than a preset threshold value, the factors such as nutrition, temperature and humidity are possibly abnormal, and a prompt is sent at the moment, so that the working personnel can know the condition in time.
