Description
Technical field
The present invention relates to a kind of plant cultivation intelligence light compensation method and system.
Background technology
In the last few years, light quality is paid attention to by the people more and more plant growth and the influence of form and is studied, growth and development of plant needs illumination, usually rely on sunshine, but vegetables, the batch production production of other economic crops such as flowers, the breeding of tissue cultivation and test-tube plantlet etc. also needs artificial light sources to replenish illumination, late fall, winter, spring, light application time more in short-term, the serious light that lacks of plant growth, crop can not normal growth, meet the cloudy day as connecting, greasy weather, the sleet sky, more can bring the growth of crop and to seriously influence, therefore, adopting artificial light source is the effective way that promotes the plant growth at the indoor crop light filling of directly giving of canopy, the output of utilizing scientific and effective plant light compensation method to improve agricultural product is an effective way that solves agriculture present situation, but at present artificial light filling can only be implemented in limited range, can not expand well, disposablely in the light filling process supply the light quantity that plant lacks, the saltus step of light filling intensity is bigger to the stimulation that plant brings like this, can not distinguish light filling to the different crop of light requirement intensity, therefore, a kind of natural law according to the plant growth, the variation of match solar irradiation, for growth and development of plants provides sufficient, rationally the intelligent light filling system of intensity of illumination is modern planting technology problem demanding prompt solution.
Summary of the invention
Purpose of the present invention namely is to overcome the deficiencies in the prior art, provides that a kind of extensibility is good, flexibility is strong, based on plant cultivation intelligence light compensation method and the system of gradient gradual manner light filling.
The objective of the invention is to be achieved through the following technical solutions: plant cultivation intelligence light compensation method, it may further comprise the steps:
(1) intensity of illumination collection: the illumination detector is gathered intensity of illumination on schedule at interval;
(2) need to judge whether light filling: intelligent light filling controller compares judgement with the current required best intensity of illumination of plant that presets in the intensity of illumination of illumination detector collection and the intelligent light filling controller, as the need light filling, then by the following light filling pattern that one or more combine, the plant in this intelligence light filling controller control range is carried out light filling:
A, automatic mode light filling: when plant needs light filling, intelligence light filling controller drives first group of plant light filling lamp L1, when the illumination detector detects illumination when still not enough, then drive second group of plant light filling lamp L2, by that analogy, the intensity of illumination behind light filling reaches the best intensity of illumination that presets;
B, the time stage mode light filling: solar irradiation intensity in one day is divided into two periods groups, each period group comprises at least four periods, in each group period with the variation of the mode match solar irradiation of gradient gradual change, open one group or several groups of plant light filling lamps with the gradient incremental manner, perhaps close one group or several groups of plant light filling lamps in the gradient mode of successively decreasing, avoid the saltus step of light filling intensity to make plant produce stress reaction;
C, manual mode light filling: according to the current intensity of illumination that shows on the intelligent light filling controller liquid crystal display, artificially judge manually opened or close plant light filling lamp group;
D, controlled mode light filling: during the quantity of the light filling lamp that can drive greater than single intelligent light filling controller when the number of the light filling lamp that adopts small-power fluorescent tube plant light filling lamp to carry out meticulous control and need, central controller is coordinated one or more intelligent light filling controllers and is made up light filling;
(3) repeating step (1) and step (2).
Plant cultivation intelligence light filling system, it comprises at least one intelligent light filling controller, at least one plant light filling lamp group, at least one illumination detector, intelligence light filling controller is connected with the illumination detector by bus, and is connected with plant light filling lamp group by light driving interface; It also comprises a central controller, and central controller is connected with intelligent light filling controller by bus; Described bus comprises the RS485 bus.
The invention has the beneficial effects as follows: adopt extendible light filling system, can carry out light filling to the large tracts of land crop simultaneously, also can be according to the different demands of different plants to intensity of illumination, select the plant light filling lamp of varying number, carry out the distinctiveness light filling, but intelligence light filling controller is independent operating also, reduced equipment cost, but simulated solar illumination changes and real-time monitoring of environmental intensity of illumination, can prevent and shift to an earlier date light filling in advance, adopt the gradient light filling, avoid light filling excessively to cause energy waste and light filling deficiency to influence problems such as plant growth.
