도1은 본 발명의 출입자 계수에 의한 조명기구 점등제어장치에 있어 절전용 센서의 개략적인 배치구조도이고, 도2 및 도3은 출입자 계수에 의한 조명기구 점등제어장치에 따른 절전센서의 동작을 설명하기 위한 사용설명도이다.Figure 1 is a schematic arrangement structure of the power saving sensor in the lighting device lighting control device according to the number of people according to the present invention, Figures 2 and 3 illustrate the operation of the power saving sensor according to the lighting device lighting control device according to the number of people. It is a diagram explaining the use.

상기 도면에 도시된 바와같이 실내로 출입하는 이동물체인 사람의 수를 계수 가능하도록 4개의 광검출기(10,11,12,13,14)가 형성되어 있고, 상기 광검출기에 적외선 광원을 조사하는 2개의 적외선광원(20,21)이 대향되게 형성되어 있다.As shown in the figure, four photodetectors 10, 11, 12, 13, and 14 are formed to be able to count the number of people moving in and out of the room, and irradiating an infrared light source to the photodetector. Two infrared light sources 20 and 21 are formed to face each other.

상기 광검출기와 적외선 광원은 출입구 양측 벽에 부착하도록 구성되어 지며, 특히 2사람이 일렬로 들어오거나 나가는 경우에도 이를 계수(검출)할수 있도록 본 고안의 센서는 2개의 적외선광원(20,21)과 4개의 광검출기(10,11,12,13)가 배치된다.The photodetector and the infrared light source are configured to be attached to both walls of the entrance and exit, and in particular, the sensor of the present invention has two infrared light sources (20, 21) so that it can be counted (detected) even when two people enter or exit the line. Four photodetectors 10, 11, 12, 13 are arranged.

여기서, 상기 4개의 광검출기는 광검출기(Photodetector)(10,12)와 (11,13)을 한쌍으로 하여 기판(30)상에 배치되어 있고, 광검출기(10,12)는 기판(30)과 거의 높이(10)가 같고 수직으로 놓여 있는 적외선광원(20)의 광을 수신하며, 광검출기(11,13)는 기판(30)과 높이는 같으나 비스듬이 놓여 있는 적외선 광원(21)으로부터의 광을 수신토록 되어 있다.Here, the four photodetectors are arranged on the substrate 30 by pairing the photodetectors 10 and 12 and 11 and 13, and the photodetectors 10 and 12 are arranged on the substrate 30. Receives light from an infrared light source 20 that is substantially the same as the height 10 and lies vertically, and the photodetectors 11 and 13 are light from an infrared light source 21 that is flush with the substrate 30 but is at an angle. It is supposed to receive.

적외선 광원(Infrared Light Source)(20)과 (21)사이의 거리는 각 광원으로부터의 빔(B1)과 빔(B2)사이에 서로 일직선으로 들어오는 출입자 사이의 어깨 폭 간격 내에 출입자의 가슴과 등 사이의 간격 이상의 차이가 나도록 정하면 된다. 폭이 좁은 출입구의 경우는 한 개의 물체만이 들어 올 수 있으므로, 도1에서 광검출기(10,12)와 적외선 광원(20)만 필요로 한다.The distance between Infrared Light Sources 20 and 21 is determined by the distance between the chest and the back of the occupant within the width of the shoulders between the beams from each light source coming in a straight line between the beams B1 and B2. You can set the difference to be greater than the interval. In the case of a narrow entrance, since only one object can enter, only the photodetectors 10 and 12 and the infrared light source 20 are required in FIG.

상기와 같이 구성된 본 발명의 출입자 계수에 의한 조명기구 점등제어용 센서의 동작을 설명하면, 도2는 출입구를 통해 두사람이 일렬로 들어올 경우 계수에 의한 조명기구의 점/소등 제어를 위한 센서의 동작을 설명하기 위한 것으로, 일렬로 이동하는 인체1(40)과 인체2(41)는 순차적으로 적외선광원(20)의 빔(B1)을 차단하여 광검출기(10)와 광검출기(12)에는 시간차를 두고 적외선 광원(20)이 차단되어 차단된 시간동안 각 광검출기(10,12)는 소정폭을 지닌 "하이"레벨신호를 발생하게 된다.Referring to the operation of the lighting device lighting control sensor according to the number of people of the present invention configured as described above, Figure 2 shows the operation of the sensor for the point / lights out control of the lighting device by the count when two people in a line through the doorway For the purpose of explanation, the human body 1 40 and the human body 2 41 moving in a row sequentially block the beam B1 of the infrared light source 20 to provide a time difference between the photodetector 10 and the photodetector 12. In addition, during the time when the infrared light source 20 is blocked and blocked, each photodetector 10 or 12 generates a "high" level signal having a predetermined width.

즉, 광검출기(10,12)의 출력단에는 각각 소정 펄스폭으로 하는 한세트의 신호가 발생되어 마이콤(50)에 전달되어 진다.That is, a set of signals having a predetermined pulse width are generated at the output terminals of the photodetectors 10 and 12, respectively, and transmitted to the microcomputer 50.

이어서, 인체1(40)과 인체2(41)가 빔(B2)를 통과 하게 되는데 위와 마찬가지로 인체1(40)의 접근에 따라 먼저 적외선 광원(21)에서 발생되는 빔(B2)은 통과되는 동안 차단되어 광검출기(11)는 소정폭의 "하이"레벨신호를 발생하고 동일한 방법으로 하여 소정시간차를 두고 인체2(41)에 의해 광검출기(13)는 "하이"레벨의 신호를 발생시키게 된다.Subsequently, the human body 1 40 and the human body 2 41 pass through the beam B2. As described above, the beam B2 generated by the infrared light source 21 first passes while the human body 1 40 approaches. The photodetector 11 generates a " high " level signal having a predetermined width, and the photodetector 13 generates a " high " level signal by the human body 2 41 with a predetermined time difference in the same manner. .

상기 각 광검출기(10,11,12,13)의 출력신호는 마이콤(50)에 입력되어 지고 이 신호를 입력받은 마이콤은 신호파형에 따라 출입자수를 계수하게 된다.The output signals of the photodetectors 10, 11, 12, and 13 are input to the microcomputer 50, and the microcomputer that receives the signals counts the number of persons according to the signal waveform.

즉, 마이콤(50)내에는 광검출기로 부터 입력되는 파형에 따라 출입하는 사람의 수를 계수할수 있도록 프로그램이 내장되어 있어 출입자수를 정확하게 계수할수 있다.That is, the microcomputer 50 has a built-in program to count the number of people entering and leaving according to the waveform input from the photodetector can accurately count the number of people.

반대로, 사람이 출입구를 통해 나갈 경우에도 각각의 광검출기는 인체가 빔(B1,B2)을 차단하는 시간동안 "하이"레벨의 신호를 출력하여 마이콤에 데이타 입력하여 나가는 사람의 수를 계수하여 현재 실내에 있는 사람의 수를 계산하게 되는 것이다.On the contrary, even when a person exits through the doorway, each photodetector outputs a "high" level signal during the time when the human body blocks the beams B1 and B2, and counts the number of people who input data to the microcomputer and exit. You will count the number of people in the room.

또한, 도3에서와 같이 한사람씩 출입하는 경우에도 각 광검출기의 출력값(파형)을 마이콤이 입력받아 계수처리함으로서 실내의 남아 있는 사람의 수에 따라 조명기구를 점/소등하도록 제어신호를 발생하게 된다.In addition, as shown in FIG. 3, the microcomputer receives and counts the output value (waveform) of each photodetector to generate a control signal to turn on / off the lighting device according to the number of people remaining in the room. do.

즉, 마이컴(50)이 실내에 사람이 있다고 판단하면 계속해서 조명기구를 점등시키고 실내에 사람이 없다고 판단되면 소등을 위한 제어신호를 발생하게 되는 것이다.That is, when the microcomputer 50 determines that there is a person in the room, the lighting device is continuously turned on, and when there is no person in the room, the microcomputer 50 generates a control signal for turning off the light.

상기 언급된 바와같이 본 발명에 따르면, 실내의 입구측에 설치되어 사람이 들어오고 나가는 수를 정확하게 계수하여 실내에 사람이 없을 경우에는 전원을 자동적으로 차단시켜 불필요한 에너지의 낭비를 방지할수 있는 효과를 지니고 있다.As mentioned above, according to the present invention, it is installed at the entrance side of the room to accurately count the number of people entering and leaving the room, when there is no person in the room automatically cut off the power to prevent unnecessary waste of energy I have it.
