Description

A kind of classroom lamp optical controller

Technical field

The utility model relates to the electrical equipment control technical field, specifically a kind of classroom lamp optical controller.

Background technology

At present, some public places such as the classroom of university, following phenomenon occurs through regular meeting:

1. the inside, classroom at noon nobody's study, but still be brilliantly illuminated in this classroom, caused the amount waste of electric power.

2. weather is sunny especially sometimes, and 5 anything but with turning on light from 9 of mornings to afternoon, but the lamp in the classroom still opening, nobody's management, to have grown energy waste the most serious the time like this.

3. will be to the operating position in the classroom detailed understanding of the class management department of school is so that more reasonably use the resource in classroom.Therefore will take statistics to every classroom turnover number weekly, the operating position in annual classroom takes statistics.

4. free display unit in the classroom, and time is too late the time, with the voice suggestion classmate rest of going back, makes things convenient for the management in classroom.

And in the middle of reality, the teaching building of a school is a lot, and the classroom is more, if with the control of manually carrying out the classroom electric light, go to check every classroom every a period of time, needs more staff certainly, certainly will will increase cost.

Operating position to the classroom: because the use in classroom is except normal giving a lesson; also have the student in the classroom, to learn; the activity of class organization; school activity; external personnel rent the classroom, and the different time within different time and the week within the classroom one day, the grade of the operating position of halves all changes constantly; if personnel selection is added up it, then be very much complicated.

Will close the door too late the time in the time in the classroom, perhaps by sweeping that the class management personnel are correlated with.At this time the staff should sweep, add again to be careful, in case the thing in classroom is stolen and destroyed, and the easiest meeting accident at this moment.Some local administrative staff will notify the student in all classrooms to leave earlier one by one, and then sweeps, and so also is pretty troublesome.

Summary of the invention

The purpose of this utility model provides a kind ofly can control classroom or other public product institute's switch lamp and voice suggestion automatically, and counts the classroom lamp optical controller into the classroom number.

Classroom lamp optical controller of the present utility model is by central control circuit, infrared tube detects input circuit, light detects input circuit, keyboard input circuit, the output display circuit, six parts such as executive circuit are formed, intelligence single-chip microcomputer SPCE061 is as the control core (being central control circuit) of this device, by infrared tube, photo resistance and keyboard detection to signal carry out the actuating of relay of processing controls output display circuit and executive circuit, reach the purpose of control light.

Concrete connecting mode is: two pairs of infrared tube detection signal outputs are connected to IOB2 and the IOB3 mouth of single-chip microcomputer SPCE061, light detects the IOB1 mouth that output signal is connected to single-chip microcomputer SPCE061, the keyboard input circuit is connected to the IOA0 of single-chip microcomputer SPCE061, IOA1, IOA2, correspond respectively to button 1, button 2, the input of button 3, the chip selection signal of output display circuit is connected to the section of IOB4～IOB7 charactron of single-chip microcomputer SPCE061 and selects signal to be connected to IOB8～IOB15, the control end of charactron clock colon is connected to IOB0, and each input of executive circuit is connected to IOA8～IOA15 of single-chip microcomputer SPCE061 respectively.

Wherein:

1, single-chip microcomputer is selected: adopt the control centre of 16 single-chip microcomputer SPCE061A as system.SPCE061A has rich in natural resources: RAM, the ROM space is big, instruction cycle weak point, fast operation, low-power consumption, low-voltage, Audio Processing able to programme, is easy to write and advantage such as debugging.Especially in the complex mathematical computing, its fast operation, the precision height, powerful aspect voice output, needn't handle direct exportable voice at external circuits.

2, infrared tube detects the infrared detection transducer in the input circuit: adopt two pairs of infrared transmitting tubes to be installed on the both sides of classroom door, then block first pair of signal between the transmitting tube receiving tube in the classroom earlier when the people enters outside the classroom, block second pair of signal between the transmitting tube receiving tube again; Then block second pair of signal between the transmitting tube receiving tube earlier when the people walks out the classroom in the classroom, block first pair of signal between the transmitting tube receiving tube again.So just can differentiate the people and enter the classroom or leave the classroom, thereby the number in turnover classroom is added up.

3. light detects the light detecting sensor in the input circuit: the input of using photo resistance to detect as light, to the light that changes within the specific limits, corresponding variation also takes place in the resistance of photo resistance, therefore can be used for detecting the power of classroom light.

4. in the output display circuit: output: what system default showed when promptly having no talent button is the time, comes the demonstration of number switching time with button, and audio frequency output was reported the time.Display part: adopt LED charactron display.LED charactron brightness height, eye-catching, low price; The time of carrying out number shows.

5. voice output module: this part is existing ripe circuit.DAC is output as current mode output, so DAC output is passed through the SPY0030 audio frequency amplifier again through behind the shunt resistance, to drive the loudspeaker playback.

The utility model detects the number that passes in and out the classroom by infrared tube, and according to light intensity current in the classroom light in the classroom is controlled.

(1) light intensity is stronger in the classroom, be fit to study and teaching, device is only added up the number that enters in the classroom, as the people enter the classroom then in the classroom current number add one, this week total number of persons add one, as the people walk out the classroom then the current number in the classroom subtract one.Light is in the state that goes out.

(2) when light intensity in the classroom a little less than, the someone enters the classroom, light is lighted at once, adds up simultaneously and to the number in turnover classroom, effect is same as above; After last people left the classroom in the classroom, light extinguished automatically after 30 seconds.

(3) time arrives 22: 45, somebody in the classroom, and device will be pointed out the people in the classroom every three minutes with voice, and the people in the classroom leaves the classroom.

(4) time arrives 23 points, no matter in the classroom whether the people is arranged, and closes the light in classroom automatically.

Advantage:

(1) number by the classroom and the light the classroom in can effective saves energy as the light on and off of decision light.

(2) by in the classroom in a year weekly number add up, the management of teaching building is had certain significance for reference.

(3) utilize the time as a signal of pointing out and turning off the light, can realize that the teaching building management is unified.

This device has wide range of applications, and not only can be used in the classroom, can also be used in the parking lot, keeps an eye on vehicle, to the vehicles passing in and out counting, turns on light when the car turnover is arranged, and does not turn off the light when having.And other public places such as station.
