Description
Technical field
The present invention relates to lighting field, more particularly, relate to lighting field and control the used a kind of illumination control system of illuminator automatically.
Background technology
The life idea of energy problem that becomes increasingly conspicuous and low-carbon (LC), environmental protection has promoted the development of new energy technology (like solar energy, wind energy etc.) and power-saving technology, and will in energy-conservation, guarantee comfortableness.Automatic illuminance controller synthesis daylight and fire-light effect through the brightness of dynamic adjustments light, reach the purpose that makes full use of natural daylight, between energy-conservation and assurance illumination comfortableness, average out.
Wherein, illumination is constant illuminating effect important index, good illumination for people produce, meaning of life is great.The illumination controller plc that common illumination control system is used is only opened light fixture when natural daylight illumination is lower than a certain threshold value, be burst type to the adjusting of illumination.But to secretly being an asymptotic process, the sudden change of illumination makes feeling under the weather of human eye by bright.And the adjusting of sudden change formula, be when natural daylight illumination is lower than a certain threshold values, to open light fixture suddenly, make light fixture remain on same brightness always, this can not satisfy different illumination requirement under the condition that natural daylight constantly changes, cause waste of electric energy easily.
In addition, existing illumination controller response speed is slow, and illumination control is inaccurate.
Summary of the invention
The object of the present invention is to provide and a kind ofly can under the condition that natural daylight constantly changes, constantly regulate the novel illumination control system of light fixture illuminance, the used illumination controller of system of the present invention can be gathered the delta data of outside natural daylight; And treatment conversion becomes control information; Be used to control the illumination of light fixture, make the illumination of entire environment remain at suitable value, make human eye comfortable; Simultaneously, saves energy.
In order to achieve the above object; A kind of novel illumination control system of the present invention comprises the illumination controller, and the output of illumination controller links to each other with the input of lamp controller; The output of lamp controller links to each other with the light fixture power supply, and said illumination controller is intelligent illumination controller; Said intelligent illumination controller comprises sensor unit and processing unit; Said sensor unit adopts and has I
2The digital sensor of C interface; Said processing unit adopts the microprocessor with PWM pwm unit.
In the course of work, total real-time brightness value in the said sensor unit induced environment, and pass through I
2C interface outputs to processing unit; Said processing unit adopts pid control algorithm to calculate the real-time brightness value signal of receiving of environment and obtains a duty ratio; This duty ratio is used to control the PWM modulation, and controlled pulse is delivered to lamp controller with this control impuls output; Lamp controller converts the control impuls of receiving to drive light fixture electric power, exports to the light fixture power supply.The sensor unit variation of brightness value in real time in the induced environment rapidly and accurately, and can control the change of lamp luminescence intensity in real time according to the variation of ambient light illumination, make illumination can not suddenly change, guarantee that the illumination in the environment satisfies the human eye requirement all the time.
The invention has the advantages that; The illumination controller that whole illumination control system is adopted is the high-resolution transducer of employing and the intelligent illumination controller that dynamical processing unit is formed; Adopt PWM light modulation method to control luminous intensity, wherein, the duty ratio of PWM control impuls adopts pid control algorithm to obtain through the real-time brightness value of system senses environment; Come the real-time regulated illuminance of lamp according to illuminance in the environment like this; Make the overall illumination of entire environment remain at a suitable value, satisfy the human eye requirement, again can saves energy.Information illumination control system response speed of the present invention is fast, and the illumination precise control is applied widely.
