抄録
A method of realizing a non-contact atmospheric temperature monitoring system using a sound probe is described. The sound probe consists of iterate burst sound of an audible frequency. The burst sound flights from an audio speaker to an electrostatic plane condenser microphone. Time of flight of the sound increases in inverse proportion to a sound propagation velocity which is dependent on the air temperature. The time of flight is acquired by correlation result between a launching burst signal and its detecting signal. This present system has a high-speed time response. Measurement error was within 0.5 degrees at the base line of 3.0m. Experimental results on this temperature monitoring system using the sound probe were in good agreement with the operation principle. This technique has the advantage of having a real-time measurement and a non-contact sensing in atmospheric monitoring.
