Description
Technical field
The invention belongs to automatic control technology field, particularly one Single-chip Controlling indoor light and curtain, make room brilliancy coordinate projector to realize intelligent linkage, reach the effect of saving manpower.
Background technology
Single-chip microcomputer as a kind of microcontroller, due to its have low in energy consumption, controlling functions is strong and the advantage such as easy to use, becomes the first-selected device implementing Based Intelligent Control gradually.Single-chip microcomputer is combined with multimedia technology, can be multimedia Based Intelligent Control and management brings a lot of convenience.At present, most of multi-media classroom or laboratory are all equipped with projector, for teacher provides more how convenient in Information Communication.Therefore, how to utilize single-chip microcomputer, improve the automatization level that multimedia environment utilizes further, become the experiment topic that is worth research.
In use, because screen is more responsive to brightness ratio, normal needs artificially adjusts indoor light or closes curtain projector, to adapt to the light needs using projector.If the mode that teacher adopts writing on the blackboard and PPT to combine carries out teaching, then when switching between two kinds of modes, need frequent open and close indoor illumination and folding curtain, the valuable class period can be wasted like this.The present invention aims to provide one Single-chip Controlling indoor light and curtain, makes room brilliancy coordinate projector to realize intelligent linkage, reaches the effect of saving manpower.
In indoor are with an automatic light meter, prior art is not be unified into an automatic light control system with projector, but independently carries out light modulation.Investigation finds, the intelligent linkage system of not head it off in existing literature and patent.
Summary of the invention
The object of the invention is the weak point for overcoming prior art, have developed a kind of indoor automatic light control system coordinating projector action, present system can make to realize intelligent linkage between room brilliancy and projector, effectively can save manpower, improves indoor light intensity and regulates efficiency.
Feature of the present invention and beneficial effect:
Present system can make to realize intelligent linkage between room brilliancy and projector, and when projector curtain falls, the light intensity in sensing chamber, as dark, is applicable to the use of projector, does not then take action; As light is comparatively strong, then close front-seat electric light, and Driving Stepping Motor is drawn the curtain together, make indoor light dimmed.Effectively can save manpower, improve indoor light intensity and regulate efficiency.The present invention combines multiple sensors, and has abundant extensibility, is a comprehensive stronger utility system.The present invention is by mains-supplied, and curtain, curtain etc. adopt real life articles for use to make, and vulnerabilities scan forceful electric power, has very strong practicality, can carry out further Product-level exploitation.
Accompanying drawing explanation
Fig. 1 is the electrical connection schematic diagram of present system.
Fig. 2 is the inventive method control program process flow diagram.
Embodiment
The present invention propose the action of cooperation projector indoor automatic light control system by reference to the accompanying drawings and embodiment be described in detail as follows:
The present invention coordinates the one-piece construction of the indoor automatic light control system of projector action as shown in Figure 1.
It is indoor that present system is arranged on projector film playback, and film playback room is provided with projector, projection screen, curtain and drives the stepper motor of its folding, and illuminating lamp; Native system comprises single-chip microcomputer, the photoelectricity door, light sensor, limit sensors, stepper motor, the relay that are connected with single-chip microcomputer respectively, and power supply; Wherein, photoelectricity door is connected with the driving mechanism of projection screen, and light sensor is arranged in the chamber interior walls near curtain, and limit sensors is connected with driving the stepper motor of curtain open/close, and single-chip microcomputer is also connected with the relay of illuminating lamp.
Native system also can arrange the manual automatic transfer valve be connected with single-chip microcomputer, according to circumstances can control manual automatic transfer valve and switch between light modulation in Non-follow control light modulation and automatic control.
System involved in the present invention utilizes said elements typical apply separately, as long as can realize the function in above-mentioned embodiment, concrete model is not limit.
In present system embodiment, single-chip microcomputer can adopt conventional control chip (as MSP430 single-chip microcomputer), and wherein, the P1.1 mouth of chip is connected with photoelectricity door, receives the curtain movement state information that photoelectricity door sends; The P1.2 mouth of chip is connected with light sensor, receives the intensity signal that it sends; The P1.3 mouth of chip is connected with stepper motor, sends the instruction of rotating forward to it; The P1.4 mouth of chip is connected with stepper motor, sends the instruction of reversion to it; The P1.5 mouth of chip is connected with stepper motor, sends to it instruction stopped operating; The P1.6 mouth of chip is connected with a limit sensors; The P1.7 mouth of chip is connected with another limit sensors, whether has moved the end of pull bar for perception curtain to; The P2.1 mouth of chip is connected with relay; The VCC mouth of chip is connected with power supply; The GND mouth ground connection of chip; The P1.0 mouth of chip is connected with manual automatic transfer valve.
Be previously stored with the control program with an automatic light meter adopting conventional programming techniques to write in above-mentioned single-chip microcomputer, each device of system that single-chip microcomputer is connected by this programmed control completes the with an automatic light meter of film playback room.
The control method with an automatic light meter that this program realizes as shown in Figure 2, comprises the following steps:
1) single-chip microcomputer receives the signal of photoelectricity door, obtains the state of projection screen, and projection screen is in holding state without system during motion, and dominant frequency is turned down, and single-chip microcomputer is in low-power consumption mode; When after the action perceiving projector curtain, first carry out initialization, associated arguments and basic status are set;
2) when projector curtain rises, curtain opened by Micro Controller Unit (MCU) driving stepper motor, and automatically detects current indoor light intensity, if when light intensity is less than the threshold value 1 of setting, relay is driven to open illuminating lamp by row, until stop driving relay when light intensity is more than or equal to the threshold value 1 of setting; Go to step 1);
3) when projector curtain declines, Micro Controller Unit (MCU) driving stepper motor cuts out curtain, stops stepper motor when curtain puts in place; And automatically detect current indoor light intensity, if when light intensity is greater than the threshold value 2 of setting, drive relay from curtain is front-seat, close the illuminating lamp in the past draining into rear row successively, until stop driving relay when light intensity is less than or equal to the threshold value 2 of setting; Go to step 1).
The value that above-mentioned threshold value 1 sets is the light intensity (in reading, writing and operating computer etc.) that indoor personnel are normally worked, and the value of threshold value 2 setting is suitable light intensity when projection is shown.
Whole process completes automatically above, does not need manual intervention, when there is fortuitous event, can will automatically control to be switched to manual control at any time.
