Abstract

건조로내에 2개의 온도센서를 일정간격을 두고 설치하여 건조로내의 온도를 감지하여 그 감지온도를 아날로그/디지탈 변환부로 디지탈 데이타로 변화하여 제어부에 입력하고 두개의 디지탈 데이타의 값의 평균값을 구하고, 사전에 산출한 기준온도 값에서 상기 평균값을 감산하여 편차를 구하고 그 편차가 0보다 크거나 같은 경우 릴레이를 온시켜 히터에 전기를 공급하여 열을 발생시키고, 편차가 0보다 작은 경우 릴레이를 오프시켜 히터에 전기를 차단하여 열발생을 멈추게 한다.Two temperature sensors are installed in the drying furnace at regular intervals to detect the temperature in the drying furnace, and the detected temperature is converted into digital data by the analog / digital conversion unit and input to the control unit. Deviation is obtained by subtracting the average value from the calculated reference temperature value, and if the deviation is greater than or equal to 0, the relay is turned on to supply electricity to the heater to generate heat, and if the deviation is less than 0, the relay is turned off to the heater. Shut off electricity to stop heat generation.
