First, in soft program process, emphasis notes infrared receiver program to be positioned among exterior terminal program, and adopt the mode directly calling delay time that the upper and lower bound receiving infrared encoded signal delay time is set, ensure with this accuracy that infrared coding burst length calculates, farthest reduce the interference be subject in infrared receiver, thus effectively improve the precision of infrared radiation receiving circuit, improve the accuracy of signals collecting, improve the precision that curtain controls.
Programming complete and loading system after, access power supply, press reset key S4, upper reset circuit conducting, and moment is to the 9th pin input high level of single-chip computer AT89C52, single-chip computer AT89C52 carries out reset operation, meanwhile, in upper reset circuit, electric capacity C3 is charged gradually, and the high level of the 9th pin of single-chip computer AT89C52 declines, gradually until single-chip computer AT89C52 has resetted.
After this, the Three models can curtain being selected according to actual needs in real time to control: MANUAL CONTROL mode, automatic control mode and time control pattern.Wherein, time control pattern is the subpattern of automatic control mode.
First judge whether to adopt automatic control mode, if not, then perform MANUAL CONTROL mode: button S1, S2 stop using, the long rotation direction controlling reducing motor by button S5 or S6, drive curtain moves up and down, and stops pushing button S5 or S6, then curtain stops mobile.
If perform automatic control mode, then judge whether to adopt time control pattern, if employing time control pattern, then perform time control pattern: first send infrared light by infrared transmitter D13, judge whether infrared remote receiver D14 and D15 receives infrared light, time control pattern if do not receive, then returns automatic control mode determining step, because only just can carry out under curtain standard-sized sheet or full-shut position.Infrared signal is received if current, then represent that curtain is in standard-sized sheet or full-shut position, now switches set S3 stops using, and first sets timing by button S5 and S6, controlled the break-make of timing control unit again by button S1 and S2, control beginning and the stopping of timing mode.
If do not perform time control pattern, then represent and directly automatically control, without the need to timing.Now switches set S3 and button S1, S2 all stop using, photo resistance R25 in light signal collection unit gathers indoor light intensity, and be transferred to single-chip computer AT89C52, under the control of single-chip computer AT89C52, voltage comparator LM339 is utilized to complete comparing between indoor actual light intensity and default etalon optical power; Infrared light is sent by the infrared transmitter D13 bottom curtain, by judging whether infrared remote receiver D14, D15 on curtain rod arm receive the position that infrared light determines the current place of curtain, control the rotation direction of reducing motor rotating shaft again in conjunction with the comparative result of voltage comparator LM339 and the current position of curtain, drive curtain to move up and down.
In conjunction with above-mentioned hardware and software, can realize freely controlling under various modes to curtain, accuracy is very high, and gets final product complete control operation by means of only simple button, very convenient, has very high practical value and application value.
Above-described embodiment is only the preferred embodiments of the present invention, not limiting the scope of the invention, as long as adopt design principle of the present invention, and the change carried out non-creativeness work on this basis and make, all should belong within protection scope of the present invention.
