상기 마이콤(2)은 입력되는 데이타신호를 소정의 프로그램으로 제어하고 제어된 신호를 출력토록 되어 있으며, 상기 온도감지수단(1)에서 입력되는 감지온도에 대한 전압값을 자체내에 구성되어있는 A/D 컨버터(도시되지 않음)의 A/D포트를 통해 상기 A/D 컨버터에서 디지탈 데이타 신호로 변환한후 이 변환된 데이타 신호를 소정의 동파방지 기준온도인가 아닌가를 판단 제어하여 제어된 신호를 순환펌프 릴레이구동부(3)에 출력토록 되어있다.The microcomputer 2 is configured to control an input data signal with a predetermined program and to output a controlled signal, and A / V having a voltage value corresponding to a sensing temperature input from the temperature sensing means 1 in itself. Through the A / D port of a D converter (not shown), the A / D converter converts the digital data signal and determines whether the converted data signal is a predetermined freeze protection reference temperature to circulate the controlled signal. It is output to the pump relay drive part (3).
상기 순환펌프 릴레이구동부(3)는 상기 마이콤(2)으로부터 제어구동신호를 받아 릴레이(RY1)를 온,오프 구동하면서 순환펌프(Pump)를 구동제어하도록 구성된다.The circulation pump relay driver 3 is configured to receive a control drive signal from the microcomputer 2 and drive control the circulation pump while driving the relay RY1 on and off.

상기와 같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.
보일러에 전원이 인가되어있는 상태에서 혹한기 또는 겨울철에 일시적이나마 온도가 급강하한 상태에서 보일러를 가동시켰을때 상기 온도감지수단(1)의 서미스터(Th)와 분압저항(R2)을 통해서 난방배관의 온도를 감지하게 되고, 이 감지된 온도에 대한 비례전압은 A/D 포트를 통해서 마이콤(2)에 입력되게 된다.The temperature of the heating pipe through the thermistor (Th) and the voltage dividing resistance (R2) of the temperature sensing means (1) when the boiler is operated while the temperature is suddenly dropped in a cold or winter season with the power applied to the boiler. Then, the proportional voltage with respect to the sensed temperature is input to the microcomputer 2 through the A / D port.
이때 상기 마이콤(2)에서는 입력되는 아날로그 신호를 A/D 컨버터를 통해서 디지탈 데이타신호로 변환하여, 이 변환된 신호가 소정의 동파방지 신호인가, 아닌가를 판단하여 제2a도에 도시한 바와같이 동파방지신호, 즉 동파방지 기준온도가 되면 마이콤(2)에서는 순환펌프 릴레이구동부(3)에 제어신호를 보내 릴레이(RY1)를 온시켜 제2b도에 도시한 바와 같이 순환펌프(Pump)를 구동시켜 줌으로서써 난방수를 난방배관에 순환시켜 동파를 방지하게 되고, 이어서 난방배관의 온도가 상승하여 온도감지수단(1)에 의하여 제2a도에 도시한 바와 같이 배관온도가 해제온도가 되면 다시 마이콤(2)을 통해서 순환펌프 릴레이구동부(3)에 제어신호를 보내 릴레이(RY1)를 오프시켜서 제2b도에 도시한 바와같이 순환펌프(Pump)의 구동정지시켜 주게되는데, 이 과정을 제3도의 플로우챠트에 의거 상세히 설명하면 다음과 같다.At this time, the microcomputer 2 converts the input analog signal into a digital data signal through an A / D converter, and determines whether or not the converted signal is a predetermined freeze protection signal as shown in FIG. 2A. When the prevention signal, i.e., the freezing prevention reference temperature, the microcomputer 2 sends a control signal to the circulation pump relay driver 3 to turn on the relay RY1 to drive the circulation pump as shown in FIG. By circulating the heating water through the heating pipe to prevent freezing, the temperature of the heating pipe rises and the temperature is increased by the temperature sensing means 1 as shown in FIG. The control signal is sent to the circulation pump relay driver 3 through (2) to turn off the relay RY1 and to stop the driving of the circulation pump as shown in FIG. 2B.According to the flowchart in detail as follows.
상기 온도감지수단(1)을 통해 감지된 데이타값이 읽어드리는 단계(100)를 거쳐 데이타값을 읽어드림과 동시에 단계(200)에서 현재 순환펌프(Pump)가 운전중인가 아닌가를 판별하게 되는데, 이때 순환펌프(Pump)가 운전중이면 단계(300)로서 현재 배관온도가 해제온도인가를 판별하게 되고, 배관온도가 해제온도이면 단계(400)로 가서 순환펌르 릴레이구동부(3)에 순환펌프(Pump)오프신호를 보내 순환펌프를 정지시키고, 상기 단계(300)에서 배관온도가 해제온도가 아니면 단계(600)로 가서 순환펌프를 자동운전시킴과 동시에, 다시 단계(300)로 가서 배관온도가 해제온도인가를 판별하여 배관온도가 해제온도이면 단계(400)로 가서 순환펌프를 정지시켜 주게된다.The data value sensed by the temperature sensing means 1 is read through the step 100 of reading the data value and at the same time it is determined whether the current circulating pump is in operation in step 200. At this time, if the circulation pump is in operation, it is determined whether the current pipe temperature is the release temperature as step 300. If the pipe temperature is the release temperature, the flow goes to step 400 and the circulation pump relay driving unit 3 is connected to the circulation pump relay driving unit 3. Pump) to stop the circulating pump, and if the pipe temperature is not the release temperature in step 300, go to step 600 to automatically operate the circulating pump, and at the same time go back to step 300 the pipe temperature is If the pipe temperature is determined to be the release temperature is determined to go to step 400 to stop the circulation pump.
한편 상기 단계(200)에서 순환펌프가 운전중이 아닌경우 단계(500)로 가서 배관온도가 동파방지온도 이하인가를 판별하여 동파방지온도 이하이면 단계(600)로 가서 펌프를 자동운전시키고, 동파방지온도 이하가 아니면 단계(400)로 가서 순환펌프를 자동정지시키도록 되어 있다.On the other hand, if the circulation pump is not in operation in step 200, go to step 500 to determine whether the pipe temperature is below the freezing prevention temperature, and if the freezing prevention temperature is less than the go to step 600 to automatically drive the pump, If it is not below the prevention temperature, go to step 400 to automatically stop the circulation pump.
이상에서 설명한 바와같이 본 고안은 혹한기나 겨울철에 일시적이나마 온도가 급강하였을때 보일러를 장시간 사용하지 않다가 보일러를 가동시켰을때 발생될 수 있는 동파방지를 위하여 난방배관의 온도를 서미스터를 이용한 온도감지수단과 마이콤을 이용하여 신속하고 정확하게 감지하여 순환펌프를 제어함으로써, 동파의 위험으로부터 보일러를 보호할 수 있는 효과를 제공해 줄수 있는 것이다.As described above, the present invention is a temperature sensing means using a thermistor for the temperature of the heating pipe to prevent freezing that may occur when the boiler is operated for a long time when the temperature suddenly increases during cold or winter. By controlling the circulation pump quickly and accurately by using and microcomputer, it can provide the effect to protect the boiler from the risk of freezing.
