Embodiment 1

[0041] like figure 1 As shown, the present invention provides a light environment control system for plant growth. The light environment control system for plant growth of the present invention at least includes a control unit 10 , a lighting component network 20 , a cloud server 30 and an information collection unit 40 .

[0042] The lighting component network 20 of the present invention is a lighting network composed of several lighting components connected in series and / or in parallel. The lighting component network includes a general driving circuit and several sub-driving circuits, and each sub-driving circuit is connected to a lighting component. Lighting components include incandescent lamps, LED lamps, OLED lamps, energy-saving lamps, lasers, xenon lamps, high-pressure sodium lamps and other light sources. Preferably, the LED lamp is a light source capable of emitting multiple visible or invisible spectrums. Preferably, the driving circuit controls the period-segmen...

Embodiment 2

[0103] This embodiment is a further improvement on Embodiment 1, and repeated content will not be repeated here.

[0104] This example is for Figure 2 to Figure 10 The change of the characteristic curve of the periodic segmented optical signal is described in detail. The variation trend of the characteristic curve of the preferred first light-emitting stage of the present invention is as follows Figure 2 to Figure 4 shown. The horizontal axis in the figure represents time, and the unit is ms. The vertical axis represents the relative brightness, the unit is not limited, expressed by the international common symbol a.u. The light-emitting period of this embodiment is preferably 20ms, the first light-emitting period is 0-5ms, the second light-emitting period is 5-15ms, and the third light-emitting period is 15-20ms.

[0105] like figure 2 and image 3 In the luminescence curves No. 1-6 shown, the luminous intensity in the first luminescent stage is constant. like Fig...

Abstract

The invention relates to a light environment control system for plant growth. An information acquisition unit sends acquired information to a cloud server with first periodic segmented optical signalsmatched with the growth characteristics of a plant; the cloud server provides at least one growth control scheme for controlling the growth of the designated plant by means the interaction of the periodic segmented change law of light and the configuration components of growth elements on the basis of market dynamic information, growth characteristic information and / or growth element information;a control unit controls the configuration components of the growth elements on the basis of the growth control schemes and selects at least one lighting component in a lighting component network corresponding to the spatial location of the plant to illuminate with second periodic segmented optical signals in accordance with the growth control schemes; and the control unit controls acquisition modules located within the area of the designated plant to send and / or receive the acquired information with the second periodic segmented optical signals which are matched with the growth characteristics of the plant and follow the periodic segmented change law.

Description

technical field [0001] The invention relates to the technical field of plant planting, in particular to a light environment control system for plant growth. Background technique [0002] The plant factory is an efficient agricultural system that realizes annual continuous production of crops through high-precision environmental control in the facility. It uses computers to automatically control the environmental conditions of plant growth such as temperature, humidity, light, CO2 concentration, and nutrient solution, so that the plant growth in the facility Labor-saving production that is not or rarely restricted by natural conditions. [0003] Light environment is an important factor for controlling plant growth in plant factories. The growth of each vegetation requires light, but the wavelength of light required by each vegetation during each growth period, as well as the irradiation time and intensity of light are different. A large number of studies and applications of...
