Detailed Description
The embodiments of the present invention are described below with reference to specific embodiments, and other advantages and effects of the present invention will be easily understood by those skilled in the art from the disclosure of the present specification. The invention is capable of other and different embodiments and of being practiced or of being carried out in various ways, and its several details are capable of modification in various respects, all without departing from the spirit and scope of the present invention. It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict.
It should be noted that the drawings provided in the following embodiments are only for illustrating the basic idea of the present invention, and the drawings only show the components related to the present invention rather than the number, shape and size of the components in actual implementation, and the type, quantity and proportion of the components in actual implementation may be changed freely, and the layout of the components may be more complicated.
According to the invention, the light accumulation amount has a proper amount according to the growth characteristics of plants, and the LED is controlled to be switched on and off by setting the light accumulation amounts of different planted vegetables so as to achieve the purpose of energy conservation.
In the case of light accumulation collection, Photosynthetically Active Radiation (PAR) is selected. PAR is the total radiation with a wavelength within 400-700nm, and the light intensity reflected by a conventional illuminometer is brightness, but the spectrum is not accurate enough as an index of light intensity when studying photosynthesis because of the change in height, cloud cover, and whether light can pass through leaves or not. The present invention uses a PPFD sensor to measure photon flux intensity.
Light quantum Flux density ppfd (photosynthetic Photon Flux density): representing the flux per second of effective photons per unit area. The unit of the light quantum flux density is mu mol/m2And s. PPFD represents the correlation between the number of photons and photosynthesis.
The cumulative threshold value of illumination for a plant growing day in the invention is as follows:
cumulative amount of illumination-PPFD x illumination time (unit μmol/m)2)
For example, lettuce can be set to 3000. mu. mol/m2。
Furthermore, the longest illumination time in one day can be controlled according to the photoperiod required by the growth of the plants, so that the growth of the plants in a dark environment is provided, and the growth rule of the plants is met. For example, 16 hours of light irradiation time may be set.
Referring to fig. 1, a flow chart of a lighting control method according to an embodiment of the invention is shown. The illumination control method may be executed in an electronic device, for example, in the form of an app, where the electronic device is a smart phone, a computer, or various wearable smart devices.
The illumination control method executes the following steps in each preset control period:
step S1: acquiring illumination time and illumination accumulated quantity;
step S2: comparing the illumination time with a preset illumination time threshold value, and comparing the accumulated illumination amount with a preset accumulated illumination amount threshold value; when it is determined that the illumination time does not reach the preset illumination time threshold and the accumulated illumination amount does not reach the preset accumulated illumination amount threshold, performing step S3; when it is determined that the illumination time reaches the preset illumination time threshold or the illumination cumulative amount reaches the preset illumination cumulative amount threshold, performing step S4;
step S3: judging whether the solar illumination intensity reaches a preset illumination intensity threshold value, if so, executing the step S5; if not, go to step S6;
step S4; and enabling the LED light supplement lamp to be in a closed state, and returning to the step S1 until the next preset control period is reached.
Step S5: turning off the LED supplementary lighting lamp and returning to the step S1;
step S6: enabling the LED supplementary lighting lamp to be in an on state, and returning to the step S1;
the preset control period is, for example, 24 hours, i.e., one day.
Through the steps, the preset illumination time threshold value and the preset illumination accumulated quantity threshold value are set according to the growth characteristics of the plants, and the illumination time and the illumination accumulated quantity are obtained in real time, so that the working state of the LED light supplement lamp is flexibly controlled, the electric energy is saved, and the best growth state of the plants can be ensured.
In another embodiment, because the LED is used as a cold light source, the LED can approach the plant canopy for effective irradiation, and the light energy utilization efficiency is improved. The traditional sodium lamp and other light source spectrums contain a large number of infrared spectrums, so that the heating value is large, and the traditional sodium lamp cannot be too close to plants. The plant height is obviously different from the seedling stage to the vegetative growth stage and even from the reproductive growth stage. Therefore, in order to improve the light energy utilization efficiency of the whole growth period of plants, the vertical height of the LED light source needs to be regulated, so that the distance between the LED light source and the canopy is relatively constant, and the purposes of energy conservation and high efficiency are achieved.
In this embodiment, the lifting system of the LED lighting source adopts a motor under the control of the PLC to drive the transmission shaft, so as to drive the winch on the shaft to rotate, wind and unwind the rope, and thus drive the light source to move up and down. The method specifically comprises the following steps:
the LED light supplement lamp is arranged on a lifting device;
when the solar illumination intensity is judged not to reach a preset illumination intensity threshold value, enabling the LED light supplement lamp to be in an on state, continuously judging whether the spacing distance between the LED light supplement lamp and the corresponding plant is smaller than a preset distance threshold value, and if so, returning to the step of obtaining the illumination time and the accumulated illumination amount; if not, sending a descending signal to the lifting device to enable the LED light supplement lamp to descend for a preset descending distance, keeping the current interval distance until the interval distance is smaller than the preset distance threshold, and returning to the step of obtaining the illumination time and the illumination accumulated amount. The preset lowering distance is set to 5cm, for example.
Further, when it is judged that the illumination time reaches a preset illumination time threshold or the illumination accumulated amount reaches a preset illumination accumulated amount threshold, for example, 3000 μmol/m has been reached2When the illumination accumulation amount is measured or the illumination time reaches 16 hours, the LED light supplement lamp is in a closed state and sends a reset signal to the lifting device so as to move the LED light supplement lamp to a preset reset position. The reset signal is usually a rising signal, the movement is usually upward movement, and the reset position can be set in a user-defined mode according to one or more of the shape of the LED light supplement lamp, the power of the LED light supplement lamp, the plant shape and the height of the lifting device.

The second judging unit 123 is configured to judge whether the solar illumination intensity reaches a preset illumination intensity threshold, and if so, turn off the LED light supplement lamp and re-execute the plant illumination parameter obtaining unit 121; if not, the LED fill light is turned on, and the plant illumination parameter obtaining unit 121 is executed again.

In a specific embodiment, the LED light supplement lamp 11 may be lowered by a preset lowering distance through multiple executions, and when the action is executed once, whether the distance reaches the preset distance threshold is determined again.
