The operating process of this device is as follows:
1. open this system, operating personnel set by environment set module 1 needs ambient brightness.As not making change, will be defaulted as the brightness of setting last time and be needs brightness, in this system works whenever the change brightness settings can be.
2. the brightness of ambient brightness acquisition module 2 automatic circle collection environment, and by communication protocol brightness value is passed to single-chip microcomputer 3.
3. single-chip microcomputer 3 will be surveyed ambient brightness value and the set environment brightness range compares, if the actual measurement ambient brightness value is lower than the setting brightness range, then increase the output duty of ratio and control the switching of first switch triode 6, increase the time of first switch triode, 6 closures, first light fixture, 7 luminous intensities are increased, make ambient brightness value increase (if this light fixture has been operated under the maximum power, ambient brightness still is lower than setting range and then opens second light fixture 8, can analogize afterwards, here have the light fixture of regulatory function to have only first light fixture 7), repeating step 3; If the actual measurement ambient brightness value is above setting brightness range, then reduce to export the switching that duty of ratio is controlled first switch triode 6, reduce the time of first switch triode, 6 closures, first light fixture, 7 luminous intensities are reduced, make ambient brightness value reduce (if first light fixture is not worked, be that pulse duty factor is 0, and 8 work of second light fixture then disconnect second light fixture 8, and ambient brightness still exceeds set point, then need artificial change environmental condition), repeating step 3.
Single-chip microcomputer is presented at ambient brightness and the present ambient brightness information of setting on the display 3, realizes man-machine interaction.
Lift a specific embodiment in conjunction with Fig. 3.
The brightness acquisition module:
The light intensity sensor module here.Follow the IIC agreement with communicating by letter of single chip computer AT mega128, be used for measurement environment brightness and give ATmega128 with brightness value, its precision can be set by single-chip microcomputer.The PD0 pin of its communication clock line SCL and ATmega128 joins, the PD1 pin of communication data line SDA and ATmega128 joins, and PD0 and PD1 are the clock line of the built-in TWI module of ATmega128 and the pin of data wire (TWI is the term of the IIC agreement of ATMEL).
The brightness settings module:
The revolving rheostat 1 here.Realize setting the function of a home from home brightness.Three pins are arranged, can the control break dividing potential drop by rotating top knob, the pin of dividing potential drop connects PF0, after the ADC module that enables ATmega128, PF0 is analog-to-digital conversion passage 0, voltage and the reference voltage of input can be compared, ratio is converted to data by certain formula and has internal register, for process analysis.
Switch triode:
The switch triode a here is used for control and opens and closes first light fixture (being LED1) here.
Switch triode b is used for the control second light fixture LED2 and opens and closes.
Light fixture:
The LED1 here and LED2: two LED lamps, they are connected on collector electrode one end of corresponding triode, and wherein LED2 has only the opening and closing two states to LED1 by a certain duty cycle pulse work of single-chip microcomputer output.
Current-limiting resistance:
One termination PB4 of current-limiting resistance 1, the base stage of another termination triode a, a termination PA0 of current-limiting resistance 2, the base stage of other end triode b, current-limiting resistance plays the effect that the corresponding triode of protection does not burn out because electric current is excessive.
Display:
The LCD1602 display here.As the output of relevant information, realize man-machine interaction.RS: state/data pin meets the PG2 of single-chip microcomputer, RW: the read/write setting meets the PG1 of single-chip microcomputer, E: enable pin meets the PG0 of single-chip microcomputer, D0～D7: data pin meets the PC0～PC7 of single-chip microcomputer.
Workflow:
At first, connect circuit, program burn writing is gone into single-chip microcomputer.Secondly, connect power supply, open single-chip microcomputer, with screwdriver rotation revolving rheostat 1 comfortable brightness range (this scope can show at LCD1602) is set.
Then, system enters self adaptation and regulates pattern, by the program of inside the precision that the light intensity sensor module is measured brightness is set, and starts it and come measurement environment brightness, the light intensity sensor module is input to the ATmega128 single-chip microcomputer with the ambient brightness data that record by the IIC agreement, deposit corresponding register, single-chip microcomputer reads the numerical value of this register, and with its calculating through correspondence, obtains the numerical value of ambient brightness, and it is issued LCD1602, brightness value is shown.Simultaneously, after obtaining ambient brightness value, itself and the comfortable brightness range of setting are compared, if ambient brightness is lower than setting range, then improve the pulse duty factor of PB4 output, LED1 is brightened gradually; Ambient brightness does not still reach satisfied if LED1 has reached the brightest, and then LED2 is opened in control, and the rest may be inferred, finally makes ambient brightness be in the comfortable brightness range of setting.If ambient brightness is higher than setting range, then control LED1 deepening gradually, (if LED1 does not work, and LED2 work, then close LED2, and make LED1 be operated in maximum power) to be that the LED lamp does not all have bright for the limit, but the brightness of external environment is greater than the brightness range of setting, this moment can only be by changing the external environment brightness that controls environment, and LED1 and LED2 do not work.More than two kinds of situations, by the working condition of control LED1 and LED2, to reach the purpose that makes ambient brightness be in the brightness range of setting.
At present, the method cane of lighting technology mainly is the improvement at the light fixture material, and aspect the regulating and controlling lamp brightness, has only by increasing resistance to come light fixture is carried out dividing potential drop, and the thermal loss of resistance is a no small waste.And this cover system, give up the method that reduces lamp brightness traditionally with series resistance, make light fixture work by discontinuity, the thermal loss that does not have series resistance, realized the efficient utilization of electric energy, and the control method of this cover system owing to the high stability of electronic device and the manufacturing that does not change existing light fixture, has very high stability and feasibility.
Although top invention has been described in conjunction with figure; but the present invention is not limited to above-mentioned embodiment; above-mentioned embodiment only is schematic; rather than it is restrictive; those of ordinary skill in the art is under enlightenment of the present invention; under the situation that does not break away from aim of the present invention, can also make a lot of distortion, these all belong within the protection of the present invention.
