Description

온도-압력 디지털 센서 측정장치{ Measuring Device of Temperature - Pressure digital sensor }Measuring Device of Temperature - Pressure digital sensor }

본 발명은 온도와 압력신호를 디지털 SENT( Single Edge Nibble Transmission )로 출력하는 온도-압력 디지털 센서 측정장치에 관한 발명이다.The present invention relates to a temperature-pressure digital sensor measuring device that outputs temperature and pressure signals as digital SENT (Single Edge Nibble Transmission).

온도 및 압력센서는 통상 압력신호와 온도신호를 각각 출력한다. 최근에는 압력신호와 온도신호를 디지털 SENT(Single Edge Nibble Transmission)로 변환하여 하나의 신호로 출력한다. 디지털 SENT 신호에는 압력, 온도, 고장진단 등의 정보가 담겨있다. The temperature and pressure sensors normally output a pressure signal and a temperature signal, respectively. Recently, a pressure signal and a temperature signal are converted into digital SENT (Single Edge Nibble Transmission) and output as one signal. The digital SENT signal contains information such as pressure, temperature, and fault diagnosis.

종래 방식대로 압력만 측정하여 출력할 경우에 디지털 SENT신호에 온도신호가 누락되어 센서 오류를 출력하여 부정확한 압력값이 출력될 수 있는 점이 제기되고 있다.When only pressure is measured and output according to the conventional method, the temperature signal is omitted from the digital SENT signal and a sensor error is output, which may result in an inaccurate pressure value being output.

또한, 온도센서의 경우 측정범위나 정확도에 따라 사용되어질 온도센서가 교체될 필요가 있음에도, 이러한 교체를 전후해 연속적인 압력측정이 중단되거나, 오차가 발생할 수 있는 문제가 있다. In addition, in the case of a temperature sensor, although the temperature sensor to be used needs to be replaced according to the measurement range or accuracy, there is a problem that continuous pressure measurement is stopped before and after such replacement or an error may occur.
