Description
Technical field
The invention belongs to intelligent desk lamp field, and in particular to a kind of intelligent desk lamp control system.
Background technology
Desk lamp is widely used by people as conventional learning tool, is generally used for the illumination of desktop, desk lamp quality is closed
It is the health to user, with the high speed development of science and technology, intelligentized desk lamp gradually steps into the life of people.
The development of desk lamp can totally be divided into three generations.The first generation is often using fluorescent tube, incandescent lamp bulb as light source, power supply mode one
As use 220V alternating currents, such desk lamp has many weak points, first, desk lamp is 220V using voltage, exists in use
Unsafe factor；Two be due to the stroboscopic effect of fluorescent tube, and this gives the eyes of the people for pipe of turning off the light long-term use of day to bring necessarily
Injury three be that power consumption is big, power consumption is larger, typically using manually operated, often cause the waste of electric energy because forgetting to turn off the light.
Second generation desk lamp, from LED as light source, there is light efficiency height, operating voltage to solve the problems, such as stroboscopic effect and power consumption
Low, the advantages that energy consumption is low, radiationless, long lifespan.And there is certain intellectuality, it can be achieved to turn on light automatically during dark surrounds.The
Three generations's desk lamp, then have higher intelligent, manual, is a kind of human body intelligent table lamp of the dc source power supply of use+5V.
This generation intelligent desk lamp more power saving, it is more environmentally-friendly, and user's sitting posture mistake can be reminded by sitting posture warning system, change
Right sitting position, to reach the purpose of the prevention deformity of spinal column and hypometropia.
For existing student, there is provided a kind of brightness of energy adjust automatically desk lamp, supervise the study of child and have more in time
The wrong sitting posture of the correction user of effect, it is necessary to which a kind of new intelligent desk lamp control system is provided.
The content of the invention
The defects of for prior art, the present invention is intended to provide a kind of intelligent desk lamp control system.
Intelligent desk lamp control system, including singlechip controller, digital tube display module, correcting sitting posture alarm module, light
Quick resistance, signal adapter, pyroelectricity module, LED drivings, LED illumination, infrared distance sensor and button, the charactron
The input of display module is connected with the output end of singlechip controller, the input and monolithic of the correcting sitting posture alarm module
The output end of machine controller is connected, and the output end of the photo resistance passes through signal adapter and the input of singlechip controller
It is connected, the output end of the pyroelectricity module is connected with the input of singlechip controller, the output of the singlechip controller
End is connected with the input of LED illumination by LED drivings, the output end of the infrared distance sensor and singlechip controller
Input is connected, and the output end of the button is connected with the input of singlechip controller.
Preferably, the singlechip controller is STC89C51 single-chip microcomputers.
Preferably, the signal adapter is ADC0809.
Preferably, the pyroelectricity module is HC-SR501, there is higher sensitivity to detected object, can quickly be rung
Should, stability is good, service life length.
Preferably, the infrared distance sensor is E18-D50NK, its transmitting with reception be it is integral, can basis
The distance of actual requirement regulation detection.
The desk lamp can pass through numeral method timing time.
The control system of the desk lamp has automatically and manually two kinds of working methods；The mode of operation and manual mode of system
Under LED luminance adjusted by button, photosensitive and analog-to-digital conversion module is that light intensity is detected by photo resistance, lead to
Cross ADC0809 to carry out signal acquisition and convert, the LED luminance under automatic mode is automatically adjusted using PWM light regulating technologies.
When human body is in the induction range of desk lamp, desk lamp automatic sensing ambient light, LED luminosity is automatically adjusted,
Automatic sensing is turned on light；When the body of user is too near to desktop, desk lamp automatic sensing, correction sitting posture is reminded.User from
Open the corresponding time then to turn off the light automatically, serve the effect for saving the energy.Manual mode is the brightness of desk lamp light not with the external world
Environmental light intensity changes and changed, and can be manually pressed by adjusting brightness button to adjust lamplight brightness.The present invention also has learning time
The function of timing, learning time can be manually set, when the time is up, desk lamp alarm, remind learning time to arrive the rest, this
When click any button can stop alarm.The distance of reaction of the pyroelectric human body inductor of use be 3m-7m or so (away from
From adjustable), actual range be generally door from desktop with a distance from, so that in dark surrounds, people one to doorway then starts desk lamp, save
The trouble turned on light is gone：The distance of infrared distance sensor is 20cm or so (apart from adjustable), and such design is to remind
Sitting posture in user's learning process is improper, pre- myopia prevention.
Advantages of the present invention：
Intelligent desk lamp control system provided by the invention, the sitting posture that can be corrected a mistake promptly, pre- myopia prevention；Light can be adjusted in time
Brightness, save resource；But also with the function of reminding the study reading time.
