Abstract
The utility model discloses a lighting energy-saving controller for classroom, which comprises an S C M, wherein a power circuit and a clock circuit are connected with the S C M, and the S C M is connected with an ambient light detection circuit, a human existence detection circuit and a light driving circuit. Users can control the work time of the controller according to daily routine, and can detect the existence of humans and the strength of ambient light within the work time of the controller. The S C M can distinguish and intelligently judge the existence signal of humans and the signal of ambient lights, and the intelligent control to the lighting circuit of a classroom can be finished according to the condition of lighting in the classroom, thereby avoiding wasting electric energy greatly.
Description
Technical field:
The utility model relates to a kind of energy-saving controller, especially a kind of simple in structure, good energy-conserving effect, the classroom illumination energy-saving controller that intelligent degree is high.
Background technology:
At present, the energy lacks the severe problem become the world and faced, and for tackling this problem, people have worked out multiple energy-conserving product, as acoustic control lamp, infrared induction lamp, illumination timing controller etc.But artificial control mode is still adopted in the illumination for the classroom, can not be at any time automatically according to the light on and off of personnel status in the classroom and daily schedule control illuminating lamp, illumination usually unmanned because of the classroom or the overshoot daily schedule causes waste of energy, brings bigger economic loss to school.
Summary of the invention:
The utility model is at the above-mentioned technical problem of existing in prior technology, and a kind of simple in structure, good energy-conserving effect, classroom illumination energy-saving controller that intelligent degree is high are provided.
Technical solution of the present utility model is: a kind of classroom illumination energy-saving controller, single-chip microcomputer is arranged, be connected to power circuit, system clock circuit with single-chip microcomputer, also be connected to ambient light detection circuit with single-chip microcomputer, human body exists testing circuit and light driving circuit.
Be connected to the remote controller receiving circuit with single-chip microcomputer.
Be connected to warning circuit with single-chip microcomputer.
Be connected to watchdog circuit with single-chip microcomputer.
The utility model with single-chip microcomputer as intelligent parts, according to the operating time of daily schedule control entire controller, can be at the existence and the testing environment light intensity of controller human body in the operating time, single-chip microcomputer is discerned and intelligent decision the exist signal and the ambient light signal of human body, the condition of rationally turning on light according to the classroom, finish Based Intelligent Control, avoided electric energy to waste in a large number the classroom illumination loop.The utility model also has multiple warning function, interference protection measure and remote controller receiving circuits such as " house dog " technology have also been adopted simultaneously, realization is to the hommization intelligent management of illuminator, has simple in structure, good energy-conserving effect, intelligent degree advantages of higher.Except that use in the classroom, also be suitable for the illumination control of occasions such as office.
Description of drawings:
Fig. 1 is the schematic block circuit diagram of the utility model embodiment.
Embodiment:
Below in conjunction with description of drawings embodiment of the present utility model.As shown in Figure 1: single-chip microcomputer is arranged, be connected to power circuit, system clock circuit, also be connected to ambient light detection circuit with single-chip microcomputer, human body exists testing circuit and light driving circuit with single-chip microcomputer.Be connected to the remote controller receiving circuit with single-chip microcomputer; Be connected to warning circuit with single-chip microcomputer; Be connected to watchdog circuit with single-chip microcomputer.
Single-chip microcomputer adopts STC89C52 model single-chip microcomputer.
Power circuit is that the 220V AC power is changed to 9V through transformer, through diode full-wave rectification, electrochemical capacitor filtering, again through three terminal regulator 7805 outputs, obtains at last+dc supply of 5V.
System clock circuit (DS12887) is in order to realize the management of controller clock because its chip internal has lithium battery, have power down after information do not lose characteristics.Can be according to the characteristics of classroom illumination use, according to Control work time daily schedule of school.
Ambient light detection circuit adopts has the function phototriode that the signal of telecommunication is amplified.It has highly sensitive, advantages such as volume is little, operating voltage is low, operating current is little, working stability, response speed is fast, the life-span is long, its base current size is directly proportional with intensity of illumination, so just can obtain the signal of telecommunication that changes with intensity of illumination on load resistance.
What there was the testing circuit employing in human body is existing pyroelectric infrared sensor.Its operation principle is: human body all has constant body temperature, generally at 37 degree, so can send infrared ray about specific wavelength 10 μ M, carries out work by surveying the infrared ray about the 10 μ M that human body launches.In order to improve detection accuracy and to suppress the interference of environment, after being strengthened by the Fei Nier filter, the infrared ray about 10 μ M of human body emission gathers on the infrared induction source.The pyroelectricity element is adopted in the infrared induction source, and this element will lose charge balance when the human infrared radiation temperature changes receiving, and outwards discharges electric charge, and subsequent conditioning circuit is handled the back after testing just can produce signal by the human body existence.
Remote controller receiving circuit, warning circuit and watchdog circuit all can adopt prior art.
The course of work:
Can control the operating time of the present utility model according to the daily schedule of school, as have a rest night, equal time vacation closing controller automatically then, with the saving electric energy.In the controller operating time, when the people enters the classroom, the infrared ray that mobile human body sends is existed testing circuit to detect and the output high level by human body, this moment, the single-chip microcomputer single-chip microcomputer was discerned and intelligent decision the exist signal and the ambient light signal of human body, according to the condition of rationally turning on light in the classroom, finish Based Intelligent Control to the classroom illumination loop.As surpassing the regulation daily schedule at night, enable overtime warning function, remind the student in the mode of sound.Take place if any emergency, then available remote controller manual mode is controlled the illuminating lamp illumination, to protect communal facility better, has also realized the hommization control of energy-saving controller simultaneously.
