(2) user, from historical data, constantly revises and improves LED plant growth lamp and run number according to vegetation growth state According to, formation formulation data model, this formulation data model is effectively combined with local photoenvironment and soil environment, treatment in accordance with local conditions Realize light filling control.
Brief description
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing Have technology description in required use accompanying drawing be briefly described it should be apparent that, drawings in the following description be only this Some embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, acceptable Other accompanying drawings are obtained according to these accompanying drawings.
Fig. 1 is the control block diagram based on the photovoltaic green-house light filling control system of PLC for the present invention;
Fig. 2 is the workflow diagram based on the photovoltaic green-house light filling control system of PLC for the present invention.
Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete Site preparation description is it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.It is based on Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of not making creative work Embodiment, broadly falls into the scope of protection of the invention.
Different plants and the different phase of plant growing, to light quality, intensity of illumination, light application time have different demands. The present invention sets up control system by equipment such as PLC, LED plant growth lamp, man machine interfaces, realizes automatically adjusting photovoltaic Save the luminous environment of plant growing under booth, promote the healthy growth of plant, and improve photosynthetic efficiency, reduce the energy and damage Consumption.
As shown in figure 1, the present invention's is included PLC, is continued based on the photovoltaic green-house light filling control system of PLC Electrical equipment, LED plant growth lamp and the man machine interface for man-machine interaction.
Control system includes light intensity sensor and PLC, and light intensity sensor monitors the illumination of environment in photovoltaic green-house Intensity, Monitoring Data is delivered in PLC;PLC is according to pre-set intensity of illumination number in man machine interface It is compared according to the intensity of illumination data collecting, according to the size of the difference of actual intensity of illumination data and setting value, determine LED plant growth lamp opens number thus realizing intensity control, writes control program, root according to different crops and user's request Determine run time according to different demand of plant growth.Relay is connected between PLC and LED plant growth lamp, and PLC is controlled Device processed is realized the opening and closing to LED plant growth lamp by relay and is controlled.
The present invention is arranged by man machine interface, shows operational factor, sets up crops and suitably grow illumination formulation model. The power supply of light filling control system of the present invention can be generated electricity by photovoltaic green-house and provide, such energy saving.
As shown in Fig. 2 the present invention is divided into manually and automatically two kinds based on the photovoltaic green-house light filling control system of PLC Pattern.
