Abstract
The invention discloses a shading method. The shading method includes the steps that whether the voltage of a battery is normal or not is judged through a single-chip microcomputer control system; if the voltage of the storage battery is abnormal, an alarm indication light is informed through the single-chip microcomputer control system, and a red light works; if the voltage of the battery is within a normal range, the expected value of expected illumination intensity, of a greenhouse, input by a user through a digital keyboard is received; after the expected illumination intensity, of the greenhouse, input by the user through the digital keyboard is received, aligning, summation and average calculation are conducted on illumination information to acquire the actual value of the current illumination intensity, wherein the illumination information is collected in the greenhouse through photosensitive sensors distributed in the greenhouse; the voltage across the two ends of electrochromic glass is adjusted according to the actual value of the current illumination intensity and the expected value of the illumination intensity. Due to the shading method, the purpose that the illumination intensity in the greenhouse can be autonomously controlled is achieved, and energy is saved.
Description
Technical field
The invention belongs to sunshade field, relate in particular to a kind of sunshading method and system.
Background technology
Existing shading system, major part is to adopt electro-motor to control the switching of booth puggaree.In temperature higher season, when sun direct projection, when illuminance is stronger, by controller, controls electro-motor and drive booth puggaree to open to carry out sunshade, avoid the crop in booth directly to be shone by the sun, cause phenomenons such as burning seedling.Such shading system, thus need user to lean on artificial judgment decision-making puggaree to open or close, understand like this because artificial judgment is usually not accurate enough flexible, and there is hysteresis quality, cannot carry out real-time guard to crop, thereby further caused, burn seedling and economic loss.
More existing technology, provide some and addressed the above problem method, for example: used sensor technology, by optical sensor, control opening or closing of puggaree, but adopt this kind of technology, in actual operation, still there is a shortcoming, controller can only be controlled opening or closing of sunshade net, that is to say and in booth, only have sunshade and two kinds of patterns of sunshade not, but this is disadvantageous to some crops in the certain illumination of necessary for growth, and the excessive use of electro-motor has caused the waste of the energy, and in practice sunshade net to open with closing be all consuming time.
Summary of the invention
Because above-mentioned shading system cannot carry out from main control, the invention provides a kind of can be in main control booth sunshading method and the system of intensity of illumination.
The present invention is by the following technical solutions:
A method for sunshade, comprising:
As a further improvement on the present invention, step 3 is specially: the reality value of more described current intensity of illumination and the difference between the expected value of described intensity of illumination, and according to described difference, and the relation of electrochomeric glass voltage and light transmittance, the magnitude of voltage at adjusting electrochomeric glass two ends.
As a further improvement on the present invention, step 2 and step 3 periodic cycle are carried out, to guarantee that the intensity of illumination in booth does not change with the change of extraneous intensity of illumination.
, comprising: single-chip computer control system, accumulator, light sensor and electrochomeric glass; Wherein,
Whether described single-chip computer control system is normal for judging the voltage of described accumulator; If the voltage of accumulator is undesired, notify alarm lamp to show red light; If the voltage of accumulator within normal range (NR), receives the expected value of intensity of illumination desired in the booth that user inputs by numeric keypad; And in receiving the booth that user inputs by numeric keypad after desired intensity of illumination, single-chip computer control system gathers the illumination information in booth by being distributed in light sensor in booth, and the illumination information of collecting is alignd to sue for peace to be averaged, and obtains the reality value of current intensity of illumination; And according to the reality value of described current intensity of illumination and the expected value of described intensity of illumination, regulate the magnitude of voltage at electrochomeric glass two ends;
Described light sensor, for gathering the illumination information of booth;
Described electrochomeric glass, for according to the magnitude of voltage at the electrochomeric glass two ends after regulating, adjusts the described illumination information receiving in collection booth.
An object of the present invention is, in the shading system of the above-mentioned type, when keeping automatically controlling the principal advantages of solar protection devices, the drive motors of abandoning tradition, use emerging photo chromic glass to replace traditional puggaree, providing is the shading system that economy is improved again performance; Liquid crystal in photo chromic glass only need change wire both end voltage in addition, makes bistable liquid crystal in glass be torqued into certain angle, while reaching the light transmittance that user expects, gets final product power-off, saves power supply.
