Distance Measurement System of High Precision Ultrasonic Based on Data Fusion

Abstract:

This paper presents a high accuracy ultrasonic ranging scheme based on MCU and puts forward a new method of multi sensor data fusion based on close degree and weight, finally get the expression of data fusion, so as to realize the multi sensors data fusion. The measuring range of this system is 3cm, range is 500cm, and the accuracy of measurement can reach 1mm. The work is stable in the measurement range 3cm-500cm that can meet the general requirements for measurement. The example analysis shows that the proposed method is more accurate than the traditional method, more suitable for the application and embedded system.
