Thermometer characteristic information generation system and thermometer characteristic information generation method

摘要

PROBLEM TO BE SOLVED: To provide a thermometer characteristic information generation system for generating thermometer characteristic information so that a thermometer can measure a temperature with high response. SOLUTION: The thermometer characteristic information generation system W1 is provided with a measuring device 110 for calculating thermometer characteristic information, and the measuring device 110 has air in an engine cylinder 11 without the engine test device 1 burning an engine E. The in-cylinder temperature of the cylinder 11 measured by the thermometer 101, the in-cylinder pressure of the cylinder 11 measured by the pressure gauge 101, and the engine 11 measured by the flow meter 103 while the compression operation is being performed. The reference temperature is calculated as the true value of the temperature inside the engine cylinder 11 by using the data acquisition unit 112 that acquires the air flow rate flowing into the engine, the state equation of the ideal gas, and the acquired in-cylinder pressure and air flow rate. It has a thermometer characteristic calculation unit 112 that calculates a transmission function of the thermometer using the reference temperature and the acquired in-cylinder temperature.
