Description
Technical field
The present invention relates to one and use single chip machine controlling circuit technology, be specifically related to based on single-chip microcomputer Lighting Control Assembly.
Background technology
Set up for the different demands that meet specific readership in reading room, is convenient to reader and concentrates the document that uses a certain scope, is also convenient to the research of librarian to specific readership and particular range document.And the reading room of school is special in student provides quiet comfortable reviewing one's lessons by oneself place or read the common reading room that certain book is established, longer with the open hour, student passes in and out reading room simple procedure, is deeply subject to student's favor.But the illumination in reading room adopts multiple days conventionally closes fluorescent tube composition, keeper according to demand people, for controlling, occurs that people walks the bright waste electric energy phenomenon that waits of lamp.Meanwhile, manual control starts or extinguishes lamp group, is difficult to adjust to suitable intensity of illumination, easily causes the visual fatigue of indoor occupant, is unfavorable for that used by students during reading study is used.So for the ease of management, optical mode control or Solar lamp have substituted the illumination of hand-guided.But the illumination of optical mode control easily exists error in judgement, when not being when artificially needing, other illumination also may allow lamp bright, or indoor darker time lamp just can start; Solar facilities output investment ratio is larger, and is easily subject to the impact of intensity of illumination, is not suitable for being used in facility place, classroom.Therefore, on market in the urgent need to a kind of easy to operate, cheap, novel energy-conserving Lighting Control Assembly of being convenient to spread.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of based on single-chip microcomputer Lighting Control Assembly, should can ensure to meet in certain area in personnel's lighting demand situation based on single-chip microcomputer Lighting Control Assembly, the workload that does not increase administrative staff, has realized intelligent control.
For solving the problems of the technologies described above, the present invention by the following technical solutions:
Based on single-chip microcomputer Lighting Control Assembly, comprise lamp group, single-chip microcomputer, light signal collection circuit, human body signal Acquisition Circuit and output control circuit, described single-chip microcomputer is connected with light signal collection circuit, human body signal Acquisition Circuit, output control circuit respectively, output control circuit is connected with lamp group, and described single-chip microcomputer is also connected with infrared emission counting circuit.
Further, on the connection line of described lamp group and single-chip microcomputer, be also provided with Manual Transfer Switch, can be according to demand, realize and automatically controlling and two kinds of patterns of hand-guided.
Further, described single-chip microcomputer is also connected with delay circuit, can pass through time-lag action, for human body signal acquisition circuit etc. provides the time repeatedly to confirm indoor occupant.
Preferably, described single-chip microcomputer is AT89C51 single-chip microcomputer.
Preferably, described lamp group comprises many group different fluorescent tubes of brightness that row puts side by side, makes it produce the fluorescent tube that brightness at least comprises two kinds of modes, meets the most suitable light of indoor occupant.
Preferably, described light signal collection circuit, light intensity detection width at least divides three width unit, and in light intensity lower limit, middle limit, the upper and lower limit of middle limit, corresponding interval lamp group has high illumination, middle illumination, low light according to three kinds of situations.
Beneficial effect of the present invention is: the present invention gathers according to different lights; output control circuit starts different lamp groups to give indoor occupant most suitable light according to the instruction receiving; make human eye obtain best protection; simultaneously; collocation human body signal Acquisition Circuit and infrared emission counting circuit carry out secondary-confirmation to personnel herein; improve lamp group and start situation; realize Intelligent control illuminating system; save to the utmost the energy; realized intelligent control, Manual Transfer Switch makes to control variation.
Brief description of the drawings
Fig. 1 is the structured flowchart that the present invention is based on single-chip microcomputer Lighting Control Assembly.
Embodiment
Accompanying drawing discloses concrete structure of the present invention without limitation, and below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, based on single-chip microcomputer Lighting Control Assembly, comprise lamp group, single-chip microcomputer, light signal collection circuit, human body signal Acquisition Circuit and output control circuit, described single-chip microcomputer is connected with light signal collection circuit, human body signal Acquisition Circuit, output control circuit respectively, output control circuit is connected with lamp group, and described single-chip microcomputer is also connected with infrared emission counting circuit.On the connection line of described lamp group and single-chip microcomputer, be also provided with Manual Transfer Switch.Described single-chip microcomputer is also connected with delay circuit.Described lamp group comprises many group different fluorescent tubes of brightness that row puts side by side.Described single-chip microcomputer is AT89C51 single-chip microcomputer.
The course of work of the present invention: hand switch, when manual, can directly be controlled lamp group opening by switch.Whether hand switch is when automatic, and single-chip microcomputer can be equipped with nobody's body induced signal according to human body signal Acquisition Circuit detecting position, have personnel to exist if system can not be determined this place, at this moment needs infrared emission counting circuit to carry out secondary-confirmation to personnel herein; If infrared emission counting circuit has error to exist, to survey by time delay, human body signal Acquisition Circuit is testing staff position again; Meanwhile, light signal collection circuit is surveyed the weak control circuit of light intensity, and in the time that light intensity signal is interval under light intensity lower limit and middle limit, light intensity signal is sent into single-chip microcomputer, and single-chip microcomputer sends a control signal to output control circuit, and lamp group enters high illumination state; When light intensity signal under middle limit with middle limit on when interval, lamp group enters middle illumination state; In the time that light intensity signal is interval with the upper limit in middle limit, lamp group enters low light according to state; When light intensity signal exceedes in limited time, lamp group is extinguished.
The present invention by hardware units such as single-chip microcomputer and light signal collection circuit, human body signal Acquisition Circuit, infrared emission counting circuits in the situation that ensureing to meet in certain area personnel's lighting demand, do not increase administrative staff's workload, realize Intelligent control illuminating system, save to the utmost the energy, realized intelligent control, Manual Transfer Switch makes to control variation.
