摘要
如何利用简单的测量系统实现精确的温度场测量,并快速而准确地重建温度场,重建算法的研究很重要。为了实现少量的声波渡越时间(ToF)较高精度的重建温度场,提出了一种新型的基于块修正插值技术的空气温度场重建算法,在被测温度场周围布置8只收发一体的超声波传感器,并将被测温度场划分为100个小区间,利用该新方法对实验室内的单热源空气温度场进行重建,重建结果与被测量的空气温度场符合。
Research on how to use a simple measurement system for accurate temperature measurement,and fast and accurate reconstruction of temperature field,the reconstruction algorithm is very important.In order to achieve a small sonic transit time time of flight（ToF） and high precision temperature field,a new algorithm for reconstruction of air temperature based on block correction interpolation technology is proposed.Around the measured temperature field 8 transceiver ultrasonic sensors are evenly layout.The measured temperature field is divided into 100 small intervals,using the new approach,a single heat source of the laboratory air temperature field is reconstructed,and reconstruction results are coincidence with the measured air temperature field.
