Embodiment
Below in conjunction with accompanying drawing the present invention is done further description.
The design of this master-slave mode remote control light modulating lamp mainly is divided into two parts: slave and main frame.System architecture diagram is as shown in Figure 1.It is kernel control chip that host and slave processors all adopts the AT89S52 single-chip microcomputer, and slave partly utilizes infrared remote control to transmit signal to main frame, is realized the adjusting of lamp start and stop and brightness then through control PWM by host machine part.In addition, main frame is through being programmed in the inner memory storage function that realizes of single-chip microcomputer; Utilize ADC0809 that the data that photo resistance collects are changed, and the process internal arithmetic realize adaptation function through the brightness that PWM controls the LED lamp.Slave system is divided into sleep/work two states, and long-time nothing operation gets into the sleep electricity-saving state automatically.
Slave mainly is made up of supervisory keyboard, single-chip microcomputer, relay indicating light and infrared transmission module, and software programming is mainly leaned in the realization of function, and is as shown in Figure 2.
The infrared remote control module adopts the serial code of pulse-width modulation during coding, be 0.565ms with the pulsewidth, 0.56ms, cycle are that binary " 0 " is represented in the combination of 1.125ms at interval; Be 0.565ms with the pulsewidth, 1.685ms, cycle are that binary " 1 " is represented in the combination of 2.25ms at interval.32 binary codes that above-mentioned " 0 " and " 1 " is formed carry out secondary modulation through the carrier frequency of 38kHz, and buffering is delivered to infrarede emitting diode after amplifying, and is converted into the infrared signal emission, and principle is as shown in Figure 3.
Main frame mainly is made up of infrared receiving module, brightness acquisition module, LED brilliance control knob, supervisory keyboard, single-chip microcomputer, relay indicating light, driver module and LED lamp.The design of host hardware circuit is simple and easy and can accomplish particular functionality, and is as shown in Figure 4.
Infrared receiving module for the infrared remote-controlled signal of having modulated, adopts integrated infrared receiving module to carry out demodulation.This module is used HS0038; Can the reception carrier frequency be the infrared remote-controlled signal of 38kHz; HS0038 outside the pulse signal that obtains remote control command, also carries out shaping and reverse output to the signal that demodulates to the received signal except having carried out amplification, amplitude limit, detection; The output signal directly gets into main control chip INTO, and is as shown in Figure 5.
The brightness acquisition module is through photo resistance the sensitization of light to be realized.When ambient light is strong more, the photo resistance resistance is just big more.The AT89S52 single-chip microcomputer detects the change in voltage at photo resistance two ends; And convert input signal into through ADC0809; The data that collect and user's setting data are carried out internal arithmetic, thereby export the brightness that different PWM controls the LED lamp, realize induced environment light; Automatically the function of adjustment LED lamp brightness is as shown in Figure 6.
Driver module selects for use LM3407 as chip for driving.LM3407 is the floating type step-down controller of the pulse width modulation of a integrated N channel power MOS FET, and its design is for constant current output accurately is provided, and is with the driving LED lamp, as shown in Figure 7.
In the slave remote control course of work, single-chip microcomputer has not detected button in one minute when pressing, and will get into battery saving mode automatically, wakes button up and presses when detecting, and single-chip microcomputer gets into normal mode of operation, and judges it is that which button is pressed.The slave workflow diagram is as shown in Figure 8.
When infrared receiving module receives data, transmit data to host SCM through host SCM external interrupt port.Infrared receiving module and supervisory keyboard on the main frame scan simultaneously, in case the instruction input is arranged, single-chip microcomputer will be made judgement, carries out function corresponding.The host work flow chart is as shown in Figure 9.
Memory storage function, photo resistance are gathered current light intensity and are passed to host SCM, and single-chip microcomputer obtains just producing a kind of PWM pulsewidth after the data, when receiving the storage button when pressing, store current LED lamp brightness data and ambient light brightness data.
Adaptation function; Carry out the brightness collection earlier; The data that collect are changed through ADC0809, in host SCM, used last time the good ambient brightness numerical value of button storage and the brightness number of LED lamp to carry out computing, control the brightness of current LED lamp with the user; Thereby realize adjusting the LED lamp automatically, make the function of the brightness of its most comfortable that reaches user's setting according to extraneous light.
Knob is regulated the brightness function, through the brightness of the LED brilliance control knob controlling LED lamp on the main frame.When knob, its resistance value changes, thereby the magnitude of voltage that causes the knob two ends changes; Host SCM is gathered knob voltage value; And be converted into input signal through ADC0809, and handle the PWM of back control output different duty, reach the effect of steady control LED lamp brightness.
The slave supervisory keyboard is provided with a plurality of function buttons, and button mainly is provided with: the ON/OFF of LED lamp, low-light level control, middle brilliance control, high brightness control, brightness storage, mode switch and sleep/operating state, 7 function keys.
" ON/OFF of LED lamp " button: this button clicks lamp and opens, and presses lamp again and closes.
" low-light level ", " middle brightness ", " high brightness " button: three buttons, each button can be controlled a gray scale of LED lamp.
" brightness storage " button: this button clicks once current brightness data of storage and current environment brightness data.
" mode switch " button: this button clicks, and forwards direct invocation pattern to from automatic mode, and accesses the LED lamp brightness of storing; This button double-clicks, and host SCM carries out computing, and according to ambient brightness, the LED lamp is adjusted into the most comfortable brightness of setting automatically.
" sleep/operating state " button: this button is pressed, and wakes the slave single-chip microcomputer up and gets into normal mode.
Also being provided with some function keys on the slave on the main frame, is can't control in order to prevent slave from losing.The system soft or hard combines, and is main with software adjustment, and it is big to repair the space, has high cost performance.
