基于虚拟仪器的超声信号测量及测距研究
Research on ultrasonic signal measurement and distance measurement based on virtual instrument
摘要
Abstract
The ultrasonic signal measurement system is designed by virtual instrument for better target detection. The system structure and working principle of each module are described. As the distance measurement is the key technology of target detection, mainly from the view of the signal processing, two kinds of envelope-based improved algorithms are proposed based on analyzing conventional algorithm of ultrasonic Time-of-Flight(TOF) measurement, and they are achieved by LabVIEW. Finally, the experiments including ultrasonic signal acquisition, storage, characteristics and amplitude analysis of echo signal and distance measurement analysis are accomplished by the measurement system. The results show that the system can get signal analysis and processing intuitively, accurate distance to provide the basis platform for post target identification.关键词
