Beneficial effect of the present invention: utilize the time set in single-chip microcomputer to carry out the timing mode switching controls of corridor lamp light, the period that flow of the people is larger between the lights, arranging light is normal on-mode, the inconvenience caused to avoid inductive switch; The period that flow of the people is less at dead of night, light is set for interrupting inductive mode, to avoid caused huge energy waste of turning on light whole night.
Accompanying drawing explanation
Fig. 1 is control circuit figure of the present invention;
Fig. 2 is basic structure schematic diagram of the present invention.
Embodiment
Below in conjunction with Figure of description, the present invention is further illustrated.
As shown in Figure 1, a timing mode control switching circuit for corridor lamp light, comprises single-chip microcomputer U1, perpetual calendar clock chip U2, human body infrared induction K switch R, resistance R1, resistance R2, electric capacity C1, triode Q1, diode D1, relay K A1, bulb LAMP, power supply VCC; Wherein, described perpetual calendar clock chip U2 is connected with single-chip microcomputer U1, the continuous reads time values of single-chip microcomputer U1, according to the time controling pattern of setting; The one termination power VCC of described resistance R1, the other end connects an I/O port of single-chip microcomputer U1 after being connected with one end of electric capacity C1 and one end of human body infrared induction K switch R; The other end of electric capacity C1 and the equal ground connection of the other end of human body infrared induction K switch R; One end of resistance R2 is connected with the 2nd I/O port of single-chip microcomputer U1, and the other end is connected with the base stage of triode Q1, the grounded emitter of triode Q1, and the collector electrode of triode Q1 is connected with coil one terminal contacts of relay K A1 with the positive pole of diode D1 respectively; The negative pole of diode D1 is all connected with power supply VCC with the coil other end contact of relay K A1; One end of bulb LAMP is connected with zero line, and the other end of bulb LAMP is connected with one end of the normally opened contact of relay K A1, and the other end of the normally opened contact of relay K A1 is connected with live wire.
Described single-chip microcomputer U1 can adopt the product of atmel corp AT89C52 model, but is not limited thereto; Described perpetual calendar clock chip U2 can adopt the product of Maxim DS12C887 model, but is not limited thereto; Described human body infrared induction switch can adopt the product of Tuo Di electronics corporation TDL ?2120 model, but is not limited thereto.
The course of work of the present invention is as follows:
As shown in Figure 2, single-chip microcomputer U1 constantly reads perpetual calendar clock chip U2, can directly read date Hour Minute Second, according to the time controling pattern of setting.
When single-chip microcomputer U1 is by the 2nd I/O port output LOW voltage, triode Q1 ends, the coil no-voltage of relay K A1, and bulb LAMP loop disconnects, and bulb LAMP is in OFF state.
When single-chip microcomputer U1 output HIGH voltage, triode Q1 conducting, the coil of relay K A1 has voltage, and the normally opened contact of relay K A1 closes, and bulb LAMP circuit closed, bulb LAMP is in illuminating state.
The realization of pattern 1: make single-chip microcomputer U1 output LOW voltage, makes bulb be in OFF state by the way.
The realization of pattern 2: make single-chip microcomputer U1 output HIGH voltage, makes bulb be in illuminating state by the way.
When realizing above-mentioned two kinds of patterns, all closedown is interrupted enable.
The realization of mode 3: make single-chip microcomputer U1 output LOW voltage, makes bulb be in OFF state by the way.But now opens interrupters is enable.
When mode 3, it is enable that single-chip microcomputer U1 opens interruption.When having people through out-of-date, human body infrared induction K switch R closes, now, the one I/O port of single-chip microcomputer U1 is ground connection low level, single-chip microcomputer is made to enter interruption, the 2nd I/O port output HIGH voltage of single-chip microcomputer U1, triode Q1 conducting, the coil of relay K A1 has voltage, the normally opened contact of relay K A1 closes, bulb LAMP circuit closed, and bulb LAMP is in illuminating state, after time delay a period of time, close.
The effect of electric capacity C1 is the stability in order to ensure human body infra-red sensor switch KR, does not namely have misoperation.
Diode D1 is fly-wheel diode.When triode drives inductor load, when triode cuts off, inductance has electric current, if do not have this fly-wheel diode, the collector electrode of triode will produce high pressure, causes triode overvoltage to burn out; If there is this diode, the loop stream that the electric current of inductance can be formed by diode is to another pole of relay, and the collector voltage of triode can higher than the conduction voltage drop of a supply voltage diode, until the energy that inductance stores discharges.Therefore the effect of diode D1 protects triode Q1 when cutting off because high pressure causes damaging.
Embodiment:
This corridor lamp light timing mode control switching circuit can be applied on corridor, students' dormitory.Morning 6 to late 6 points, natural daylight is sufficient, corridor lamp light can be allowed to be in full-shut position, i.e. pattern 1; Evening 6 to late 12 points, natural daylight is not enough, and is now that student's discrepancy amount is more multi-period, corridor lamp light can be allowed to be in full-gear, i.e. pattern 2, to remove trouble and the loss of frequent closedown from; Evening 12 to 6 points morning, natural daylight is still not enough, but the personnel that now come in and go out are few, and corridor lamp light can be allowed to be in inductive switch state of a control, i.e. mode 3, with energy savings.
The timing controlled of single-chip microcomputer, realizes easily by the designated parameter in reprogramming, so according to the requirement of different occasion, Various Seasonal etc., can arrange and change flexibly the duration of various pattern voluntarily, with the various demands of applicable user.
