Abstract
A fully automatic illuminating switch includes an infrared transmitting pipe, an infrared collection tube and a single-chip computer. The single-chip computer distinguishes the direction and the number of people through two pairs of infrared transmitting and receiving pipes on a doorframe with one pair being close to the outside of the door and the other pair being close to the inside of the door. If someone ingresses or egresses the room through the door, the single-chip computer does plus-minus operation of the number of the people. If the operational result is more than zero, which means there are people in the room, the lamp is on while if the operational result is zero, which means there are no people in the room, the lamp is off.

Program in the monolithic computer (IC3) is work like this: behind monolithic computer (IC3) electrification reset, at first its inner timer/counter T1 is set to counting mode, make 19 pin output low levels then, 15 pin output high level, DS1 starts working, DS2 does not work, after postponing a bit of time, with counter T1 zero clearing, make 18 pin allow DF1 send the infrared light pulse of a certain quantity to DS1 again by Q1, DS1 becomes the infrared light pulse signal that receives into electric impulse signal, and this electric impulse signal is through amplifying, be sent to 9 pin of monolithic computer (IC3) after the shaping, i.e. the T1 pin, when the quantity that goes out pulse when the value and 18 human hair combing wastes of this moment record among the counter T1 equates, there is not shelter between expression DF1 and the DS1, otherwise, between expression DF1 and the DS1 shelter is arranged.If do not have shelter between DF1 and the DS1, monolithic computer (IC3) just makes 15 pin become low level, 19 pin become high level, DS2 starts working, DS1 quits work, after postponing a bit of time, with counter T1 zero clearing, make 14 pin allow DF2 send the infrared light pulse of a certain quantity to DS2 by Q2 again, DS2 becomes the infrared light pulse signal that receives into electric impulse signal, and this electric impulse signal is through amplifying, be sent to the T1 pin of monolithic computer (IC3) after the shaping, when the quantity that goes out pulse when the value and 14 human hair combing wastes of this moment record among the counter T1 equates, there is not shelter between expression DF2 and the DS2, otherwise, between expression DF2 and the DS2 shelter is arranged.If do not have shelter between DF2 and the DS2, monolithic computer (IC3) just repeats the work behind the electrification reset.
When the people enters the room by door, the people at first becomes shelter between DF1 and DS1, monolithic computer (IC3) just detects the state between DF1 and the DS1 after detecting this state repeatedly, till no longer including shelter between DF1 and the DS1, subsequently, monolithic computer (IC3) begins to detect the state between DF2 and the DS2, and at this moment two kinds of possibilities are arranged: the one, there is not shelter between DF2 and the DS2, and the 2nd, have.If do not have shelter between DF2 and the DS2, just represent that the people comes the doorway and returned again for a certain reason later on, promptly this person does not enter this room, and monolithic computer (IC3) is not done plus and minus calculation.If between DF2 and the DS2 shelter is arranged, just represent that this person has entered this room, monolithic computer (IC3) just allows the counter of record turnover number add one, and make 11 pin become low level, promptly turns on light.
When the people goes out the room by door, the people at first becomes shelter between DF2 and DS2, monolithic computer (IC3) just detects the state between DF2 and the DS2 after detecting this state repeatedly, till no longer including shelter between DF2 and the DS2, subsequently, monolithic computer (IC3) begins to detect the state between DF1 and the DS1, and at this moment two kinds of possibilities are also arranged: the one, there is not shelter between DF1 and the DS1, and the 2nd, have.If do not have shelter between DF1 and the DS1, just represent that the people comes the doorway and returned again for a certain reason later on, promptly this person does not go out this room, and monolithic computer (IC3) is not done plus and minus calculation.If between DF1 and the DS1 shelter is arranged, just represent that this person has gone out this room, monolithic computer (IC3) just allows the counter of record turnover number subtract one.If the value in the counter of record turnover number is zero, just make 11 pin become high level, promptly turn off the light.
The people that whenever enters, monolithic computer (IC3) will allow the counter of record turnover number add one, and the people that whenever comes out will allow the counter of record turnover number subtract one.As long as the content of this counter non-vanishing (expression has the people in the room), lamp just keeps bright state.The content of counter has been zero (expression has been had no talent in the room), and lamp just is switched off.
Monolithic computer (such as AT89C2051) combines with real-time timepiece chip (such as DS12C887), can follow the tracks of sun set/raise time throughout the year, thereby judge day and night.If go to control the 12V DC power supply of powering to the utility model with the above-mentioned circuit that can judge day and night, just can allow the utility model work night, do not work daytime.
