Abstract

본 발명은 쇳물 등의 고열의 온도를 측정하여 디지털로 표시하는 디지털 온도 측정방법에 관한 것으로서 종래의 디지털 온도 측정장치는 선형화 회로의 구성이 매우 복잡하고 고가이므로 제품의 생산원가를 상승시키게 되고, 또한 선형화 회로의 온도편차가 매우 크게 발생하여 온도 표시부에 표시되는 온도와 실제의 쇳물의 온도간에는 많은 온도차가 발생하였다.The present invention relates to a digital temperature measuring method for measuring and displaying a high temperature of the temperature, such as a high temperature digitally, the conventional digital temperature measuring device is a complex and expensive configuration of the linearization circuit to increase the production cost of the product, and also The temperature deviation of the linearization circuit was very large, causing a large temperature difference between the temperature displayed on the temperature display and the actual temperature of the water.

본 발명은 선형화 회로를 사용하지 않고, 마이콤내에 미리 열전대 센서의 검출신호에 따른 온도의 룩업 테이블을 저장하여 두고, 열전대 센서의 검출신호를 디지탈 신호로 변환한 후 이에 따른 해당온도를 마이콤이 룩업 테이블에서 찾아 온도 표시부에 표시함으로써 쇳물의 온도를 정확히 측정하여 표시할 수 있다.The present invention stores a lookup table of the temperature according to the detection signal of the thermocouple sensor in advance in the microcomputer without using the linearization circuit, converts the detection signal of the thermocouple sensor into a digital signal, and then converts the corresponding temperature accordingly into the lookup table of the microcomputer. It is possible to accurately measure and display the temperature of the molten metal by finding in and displaying it on the temperature display part.
