본고안은 대별하여 주제어부(210)가 구동회로부(220)로 이루어 지는바, 구동회로부(220)는 3φ교류전원선에 계전기 접점을 통하여 Y결선된 히타(H)와 공기급송용 휀모타(M)를 결합하여 이루고, 주제어부(210)는 상기 3φ교류전원선으로 부터 단상출력을 인출하여 제1 변압기(T1)와 제2 변압기(T2)를 접속하고 상기 제2 변압기(T2)의 입력을 개폐하는 전원스위치(SW1)와, 상기 제1 변압기(T1) 출력단계 3φ전원개폐용 계전기(MC)와 서모스탯(TS)그리고 테스트스위치(SW2)를 직렬로 접속하고 이 테스트스위치(SW2)에 병렬로 릴레이(RY2)접점(ry)를 연결하며, 상기 제2 변압기(T2)출력단에 DC24O를 형성하는 제1 전원부(P1)와 그 구동표시등(LED1)을 형성하되 공조기 구동용 계전기(103)의 b접점(103b)을 통하여 DC 5V를 형성하는 제2 전원부(P2)와 그 구동표시등(LED2)를 연결하여 이루고, 공조실내 온도를 검출하는 서미스터(TH)를 통하여 이 검출온도값을 증폭하는 증폭부(11)와, 이 증폭된 출력을 설정온도값과 비교출력하는 비교부(12)와 이 비교부 출력시 릴레이(RY2)를 구동하도록된 릴레이구동부(13) 및 릴레이 구동을 표시하는 표시등(LED3)로서 이루어지는 온도제어부(1)와, 상기 서미스터(TH)출력에서 분기하여 증폭부(21)와 이 증폭된 출력을 이상상태의 상한온도설정값과 비교출력하는 비교부(22)와, 비교부 출력을 일시지연 출력하는 지연구동부(23)를 연결하고, 정상 상태에서 온 구동하는 릴레이(RY1)와 그 릴레이 구동부(25)와, 이상 상태에서 상기 지연구동부(23)의 출력으로 전기기동부(25)의 구동을 제한하여 릴레이(RY1)를 오프 시키는 제한 구동부(24), 그리고 상기 지연구동부(23)의 출력을 표시하는 표시등(LED4)로서 된 이상상태 검출구동부(2)와, 상기 이상상태 검출구동부(2)의 릴레이(RY1) b접점을 개재하여 별도전원에 고장표시용 부저(BZ)를 접속하여 이루어 지는 것이다.Mainly, the main control part 210 is composed of the driving circuit part 220. The driving circuit part 220 has a Y-connected heater (H) connected to a 3φ AC power supply line through a relay contact and an air feeding fan motor (M). ), And the main control unit 210 draws a single-phase output from the 3φ AC power supply line to connect the first transformer T 1 and the second transformer T 2 to connect the first transformer T 1 to the second transformer T 2 . A power switch SW 1 that opens and closes an input, the first transformer T 1 output stage 3φ power supply switching relay MC, a thermostat TS, and a test switch SW 2 are connected in series, and this test is performed. A first power supply P 1 and a driving indicator LED 1 for connecting a relay RY 2 contact ry to a switch SW 2 in parallel and forming a DC 24 O at an output terminal of the second transformer T 2 . ) for forming a connection but the second power supply (P 2) and (LED 2) such that the drive display for forming a DC 5V via the b-contact (103b) of the air conditioner drive relay 103 for In addition, an amplifying unit 11 for amplifying the detected temperature value through a thermistor TH detecting the temperature in the air conditioning chamber, a comparator 12 for comparing the amplified output with a set temperature value and the comparing unit and a temperature control unit (1) comprising as the to drive the output when the relay (RY 2) a relay driver 13 and the indicator (LED 3) indicating the relay driving, by branching from the thermistor (TH), an output amplifier portion (21 ) And a relay unit which connects the amplified output with the upper limit temperature set value of the abnormal state and the delay unit 23 which temporarily outputs the output of the comparator unit and connects the relay unit. RY 1 ) and its relay driver 25, and a limit driver 24 for turning off the relay RY 1 by limiting the driving of the electric starting part 25 to the output of the delay driver 23 in an abnormal state, and And an indicator LED 4 indicating the output of the delay driver 23. The fault indication buzzer BZ is connected to a separate power supply via the abnormal state detection driving unit 2 and the relay RY 1 b contact of the abnormal state detecting driving unit 2.
여기서 상기 표시등(LED1-LED4)는 제어장치(200)에 형성되며 상기 부저(BZ)는 필요의 장소에 연장형성하는 것을 바람직하게 생각할 수 있다.In this case, it is preferable that the indicator LED 1- LED 4 is formed in the control device 200 and the buzzer BZ extends to a required place.
상기와 같은 본 고안은 전술한 바와같이 공조기 구동용 계전기(103)의 b접점을 전원부(P1P2)간에 개재하여 구성함으로써 공조기(101)가 구동될때는 제어장치(200)의 각 회로의 전원 DC5V가 차단되어 정지 상태가 되게하고, 공조기 정지시에 극한하여 설정온도 이하에서만 히타(H)와 휀모타(M)가 동작하여 공조실내 온도를 일정하게 유지하게 한다.As described above, the present invention is configured such that the b contact of the air conditioner driving relay 103 is interposed between the power supply units P 1 P 2 so that the air conditioner 101 is driven. The power supply DC5V is cut off to be in a stopped state. When the air conditioner is stopped, the heater (H) and the motor (M) operate only at the set temperature or less to keep the temperature inside the air conditioning room constant.
그 작용을 살펴보면, 공조실내에 본 고안을 설치하고 비교부(12, 22)의 기준전압을 각각 작동온도값과 이상상태에서의 상한설정 온도값으로 설정한다.Looking at the operation, the present invention is installed in the air conditioning chamber and the reference voltages of the comparators 12 and 22 are set to operating temperature values and upper limit set temperature values in an abnormal state, respectively.
이후 서미스터(TH)와 직렬 연결된 분압저항에 의거 분압된 값은 현재의 온도값으로 증폭부(11)에서 증폭되어 비교부(12)에 비교입력되고, 작동온도로 설정된 값인 기준전압과 비교되어 설정값 이상일 때 차동 출력되어 표시등(LED3)을 구동시키면서 릴레이 구동부(13)를 경유 릴레이(RY2)를 여자시켜 그a접점(ry2)이 온 되게되고 따라서 히타(H)와 휀모타(M)에 전력공급을 이루는 계전기(MC)는 제1 변압기 출력으로서 여자되게 된다.After that, the voltage divided by the voltage divider connected in series with the thermistor (TH) is amplified by the amplification unit 11 at the current temperature value and compared to the comparison unit 12 and compared with the reference voltage which is a value set as the operating temperature. When the value is equal to or greater than the differential value, the indicator LED 3 is driven, and the relay driver RY 2 passes through the relay RY 2 to excite its contact ry 2 so that the contact point ry 2 is turned on. Thus, the heater H and the motor ( The relay MC, which powers M), is excited as the first transformer output.
그리하여 히타(H)와 휀의 구동으로 공조실내에는 열풍이 공급되어 동파를 방지하게 되는 것이다.Thus, the hot air is supplied into the air conditioning chamber by the driving of the heater H and 휀 to prevent freezing.
열풍이 순환되어 공조실내에 온도상승이 이루어 지게 되면, 상기 서미스터(TH)의 저항값이 변화되어 비교부(12)출력이 없어지게 되면 릴레이(RY2)가 소자되고 따라서 계전기(MC)가 연동하여 소자되어 히타9H)와 휀모타(M)는 정지되게 된다.When the hot air is circulated and the temperature rises in the air conditioning chamber, the resistance value of the thermistor TH is changed and the output of the comparator 12 disappears, so that the relay RY 2 is decomposed and thus the relay MC is interlocked. The heater 9H and the shock motor M are stopped.
여기서 소비전력을 고려하여 하한온도를 대략 5℃, 상한온도는 대략 6℃정도가 되도록 비교부(12)의 기준전압을 설정함이 바람직하다.Here, it is preferable to set the reference voltage of the comparator 12 such that the lower limit temperature is approximately 5 ° C. and the upper limit temperature is approximately 6 ° C. in consideration of power consumption.
그런데 히타와 휀의 이상등에 의한 히타과열 또는 히타 용량부족이 발생하게 되면 상기 서미스터(TH)의 검출값은 증폭부(21)를 경유, 이상상태의 상한온도값이 기준전압으로 설정된 비교부(22)에 입력되고 그 출력이 있게되면 일시지연 시킨후 지속될때에는 이상상태를 간주하여 여자상태에 있던 릴레이(RY1)를 제한구동부(24)가 구동하여 소자상태를 하며 따라서 그 b접점이 폐로되면 위 부저(BZ)가 경보구동을 행하게 된다.However, when a heater overheating due to an abnormality between the heater and the power supply or a lack of the heater capacity occurs, the detection value of the thermistor TH is passed through the amplifier 21, and the upper limit temperature value of the abnormal state is set as a reference voltage 22. ) If the output is present and the output is delayed, then it is regarded as an abnormal state and the limiting drive unit 24 operates the relay RY 1 that was in the excited state to operate the device. The buzzer BZ performs the alarm drive.
물론 상기 고장등에 부가하여 히터전원상에는 서모스탯(TS)가 개재되어 극단적인 과열을 2차적으로 방지하게 한다.Of course, in addition to the failure, the thermostat (TS) is interposed on the heater power supply to prevent extreme overheating secondary.
그리하여 공조실내는 항상 일정온도 유지가 가능하게 되며, 이상고온으로의 상승은 배제되므로 무인 운전이 가능한 것이다.Thus, the air conditioning room can be maintained at a constant temperature at all times, and the rise to abnormal high temperatures is excluded, so that unmanned operation is possible.
다음으로 상기 본 고안에 더하여 원격감시가 가능하도록 하며 컴퓨터상에서의 중앙제어가 가능하도록된 본 고안의 다른 실시예에 대하여 살펴보고자 한다.Next, in addition to the present invention, it will be described with respect to another embodiment of the present invention to enable remote monitoring and to enable the central control on a computer.
제3도 및 제4도에 있어서, 상기 각 표시등(LED1-LED4)에 병렬로 각각 릴레이(RY1-RY4)를 연결하고, 각 릴레이의 a접점(ry1-ry4)에 직렬로 상호값이 상이한 저항(R1-R4)을 각각 연결하여 상호 병렬 접속하여 송신모듈(3)을 이루고, 상기 저항(R1-R4)값을 판독하기 위하여 해당 합성저항을 통한 전압값을 기준전압으로 하는 상기 저항과 동수의 비교기로된 판독부(41)와, 이 판독부(41)의 각 비교기 출력단에 각각 표시등(LED1-LED4)과 드라이브어레이를 연결하여된 드라이버(42)와, 상기 각 드라이브 어레이에 각각 직렬로 릴레이(RY11-RY14)를 집약 구성한 릴레이부(43)와, 상기 릴레이(RY11-RY14)의 a접점으로 4진 코드값이 형성되도록 이루어진 접점부호부(44) 및 그 전원부(45)로서 구성되는 수신모듈(4)을 포함하여 이루어지는 것이다.3 and 4, relays RY 1 to RY 4 are respectively connected in parallel to the respective indicators LED 1 to LED 4 and connected to a contact ry 1 to ry 4 of each relay. The resistors R 1 to R 4 having mutually different mutual values are connected in series to be connected in parallel to each other to form a transmission module 3, and to read the values of the resistors R 1 to R 4 , the voltage through the corresponding synthetic resistor. A driver having a readout unit 41 having the same number of resistors as the reference voltage and a comparator, and an indicator light (LED 1- LED 4 ) and a drive array connected to the output terminals of the comparator 41, respectively. 42, a relay (RY 11 -RY 14) configured to aggregate the relay unit 43, and this binary code value 4 with a contact of the relay (RY 11 -RY 14) formed in each series in each of the drive array And a receiving module 4 configured as a contact code portion 44 and a power supply portion 45 thereof.
이 경우에는 원격감시및 컴퓨터를 통한 감시가 가능하도록 4진코드값을 제공하려는 것인바 살펴보기로 한다.In this case, let's look at the purpose of providing a binary code value for remote monitoring and computer monitoring.
상기 설명된 바와같이 전원이 정상적으로 인가되면 전원표시등(LED1)이 점등되고, 공조기가 정지된 상태일 때 계전기(103)의 b접점(103b)가 폐로되면서 제2전원부(P2)가 구동되면서 운전표시등(LED2)가 점등되며, 정상적인 가온상태일때는 가동표시등(LED3)이 이상고온등의 이상상태 검출시 그 구동부(2)가 구동됨과 동시에 접점표시등(LED4)이 점등된다는 것을 알수 있을 것이다.As described above, when power is normally applied, the power indicator LED 1 lights up, and when the air conditioner is stopped, the b contact 103b of the relay 103 is closed and the second power supply unit P 2 is driven. The operation indicator (LED 2 ) is turned on while the operating indicator (LED 3 ) detects an abnormal state of abnormal high temperature such that the driving unit (2) is driven and the contact indicator (LED 4 ) is turned on at the time of normal heating. You will notice that it lights up.
이 운전상태의 감시를 공조실 부근에서 행하지 아니하고 원격(별도의 중앙제어실)에서 감시 할 때 매우 유용하다.This operation is very useful when monitoring remotely (separate central control room) without monitoring the operating condition.
즉, 상기 각상태에서 구동하는 표시등(LED1-LED4)에 병렬로 동시 동작하는 릴레이(RY1-RY4)를 각각 연결하고 상기 각 릴레이(RY1-RY4)을 직렬로 하여 상호 병렬 합성저항값을 출력하도록 된 송신모듈(3)은 히타와 휀의 운전상태에 따라서 구동하는 당해 릴레이(RY1-RY4)에 따라 그 출력 저항(R1-R4)의 합성저항값에 따른 전압이 상이하게 됨을 알수 있을 것이다.That is, the relays (RY 1- RY 4 ) simultaneously operating in parallel to the indicators (LED 1- LED 4 ) driven in each state are connected to each other in series with each of the relays (RY 1 -RY 4 ) in series. The transmitting module 3, which is configured to output the parallel composite resistance value, corresponds to the composite resistance value of the output resistors R 1- R 4 according to the relays RY 1- RY 4 driven according to the operating state of the heater and power. It will be seen that the voltages are different.
따라서 이 출력을 라인(L1,L2)로서 수신모듈(4)에 연결시켜 각 비교기가 당해합성저항값에 따른 고유의 기준전압을 형성하여 줌으로써 각 상태에 따른 비교기 구동이 이루어지게 되고 이 비교기의 구동레벨에 따라서 판독된 값은 상기 표시등(LED1-LED4)과 일치하는 표시등(LED1-LED4)를 점등시키면서 드라이버(42)를 경유 당해 릴레이(RY11-RY14)를 온 구동시켜 그 a접점을 폐로 되게 하여 공지된 컴퓨터의 직렬데이타 형태로 4진 코드로서 전송될 수 있게 하는 것이다.Therefore, this output is connected to the receiving module 4 as lines L 1 and L 2 so that each comparator forms a unique reference voltage according to the synthesis resistance value, thereby driving comparators according to each state. The value read out according to the driving level of the relay (RY 11 -RY 14 ) via the driver 42 while lighting the indicator (LED 1 -LED 4 ) corresponding to the indicator (LED 1 -LED 4 ). The on contact is closed so that the a contact is closed so that it can be transmitted as a binary code in the form of serial data of a known computer.
따라서 원격에서도 감시가 가능하는 것을 알수 있다.Therefore, it can be seen that remote monitoring is possible.
