Description
Technical field
The present invention relates to control circuit technical field, be specifically related to a kind of interior illumination control system.
Background technology
Along with expanding economy and scientific and technological progress, people are also more and more higher to the requirement of illumination, and traditional manual lighting control system technology has been subject to the intense impact in epoch, and " intelligent lighting " technology occurs thereupon, and promptly advances.General manual control system refers to the switching of individual by button, select Elopichthys bambusa, lift or system that the single switch of remote controller and other approach executable operations or one group of switch and light modulating device form, there is small scale, with low cost, but along with people pursue automation, intellectuality, energy-saving, manual control system more and more can not meet people's demand.For example, when not needing to throw light on, whether turn off the light and be decided by think factor completely,, lighting apparatus more place (as classroom, market etc.) long to some lighting hours, the use wasting phenomenon of its illuminator is of common occurrence.With regard to the illuminator of existing intelligent building, the lamp in many places is often from morning to night to open, no matter whether these rooms or corridor have people, also no matter there are how many people.Or when natural luminosity is fine, lamp can not be closed in time; Otherwise, when natural daylight illumination can not meet people's demand, can not open in time light again.According to statistics, in building energy consumes, only illumination just accounts for 33%, 40% left and right of all power consumptions of power consumption Zhan Qi unit of this phenomenon, so lighting energy saving becomes more and more important.The universal power down switch using has sound control type, touch-type, photosensitive type etc. substantially both at home and abroad now.These several switches respectively have the drawback of oneself, although can automatically close and can not automatically open as sound control type is not suitable for the noisy place of environment, touch-type, optical switch can not automatically turn off the light during unmanned.
Summary of the invention
For solving above-mentioned deficiency, the present invention will provide a kind of interior illumination control system, can configure the open and close that realize Based Intelligent Control room lighting equipment with control circuit by software, and the light intensity in automatic conditioning chamber.
The present invention is achieved through the following technical solutions: interior illumination control system, comprise single-chip microcomputer, delay selection circuit, relay, ambient brightness sensing module and pyroelectric infrared sensor, wherein the input of single-chip microcomputer is connected with delay selection circuit, ambient brightness sensing module and pyroelectric infrared sensor, and its output is connected with relay.
In such scheme, the input of described single-chip microcomputer is also connected with reset button, and its output is also connected with a force switch button.
In such scheme, described ambient brightness sensing module is all connected with the input of single-chip microcomputer with pyroelectric infrared sensor after an isolation buffers.
In such scheme, described single-chip microcomputer can be AT89C52 single-chip microcomputer.
The invention has the beneficial effects as follows:
The present invention utilizes pyroelectric infrared sensor and photoelectric sensor to come to have or not in sensing chamber personnel and indoor brightness, use AT89C52 single-chip microcomputer that signal is analyzed, processed and controls, and coordinate the setting of software program, and realized lighting apparatus Based Intelligent Control, reach energy-conservation object.The illumination that is applicable to the indoor places of large area such as school, market is controlled, and can effectively lighting apparatus be controlled automatically, reaches energy-conservation object.
Accompanying drawing explanation
Fig. 1 is the block diagram of interior illumination control system of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described.Should be appreciated that preferred embodiment described herein, only for description and interpretation the present invention, is not intended to limit the present invention.
As shown in Figure 1, interior illumination control system of the present invention, comprise single-chip microcomputer, delay selection circuit, relay, ambient brightness sensing module and pyroelectric infrared sensor, wherein the input of single-chip microcomputer is connected with delay selection circuit and reset button, ambient brightness sensing module is all connected with the input of single-chip microcomputer with pyroelectric infrared sensor after an isolation buffers, and its output is connected with force switch button with relay.
In the present embodiment, from the consideration of functional requirement and cost, described single-chip microcomputer is AT89C52 single-chip microcomputer, realizes the control to the detection of illuminance and luminous intensity.
Described pyroelectric infrared sensor is selected P2288 passive pyroelectric infrared sensor of the human body, adopts the poor working method of balance inspection, and application performance is stable: when indoor module output 3.3V voltage while having people, be low level during nobody.
The photoelectric sensor that the photo resistance that described ambient brightness sensing module employing model is MJ3516 is core, adopts photo resistance that ambient brightness is converted to corresponding magnitude of voltage, then by input the digital signal of a standard after amplifier to single-chip microcomputer.
Described delay selection circuit is the timing of single-chip microcomputer timer internal.By reading external parameter, make monolithic function realize the timing without the time, its objective is that lighting apparatus time delay one end automatic distinguishing after the time, reaches energy-conservation object when ambient lighting is weak.
Described relay adopts electromagnetic relay, and the control end of this relay is connected with lighting apparatus.
The operation principle of interior illumination control system of the present invention is: 1) single-chip microcomputer opening or closing by Control lighting apparatus; 2) single-chip microcomputer around detects lighting apparatus by lighting detecting circuit, if brightness meets living needs, keeps the closed condition of lighting apparatus; If brightness not, by single-chip microcomputer, detect whether collected human body pyroelectricity transducing signal simultaneously; 3) if while human body signal being detected, single-chip microcomputer is controlled at once lighting apparatus and is opened, if single-chip microcomputer does not detect human body signal, Single-chip Controlling lighting apparatus continues to keep closed condition; 4) when lighting apparatus is opened, if a certain moment single-chip microcomputer can't detect human body signal, after time delay a period of time, close, if human body signal detected again between time delay, finish time delay; 5) according to applied field in one's power end user group's difference can different delay time values be set by the state of single-chip microcomputer P1.0～P1.4 pin is set; 6) under circuit normal operation, as long as by pressing pressure button, just can carry out to lamp the control of force switch, by this button, also can make circuit switch to automatic control state.
