A Method to Improve the Accuracy of the Ultrasonic Detection for Drainage Pipeline

Abstract:

This paper presents a method of how to improve the accuracy of the ultrasonic detecting for drainage pipeline. The method is composed of two parts. One is the hardware, which provides a multiplexer that gradually amplifies the echo signal. The other is the software, decreasing the reference voltage step by step at a fixed value as the microprocessor controls. With the cooperation of the hardware and the software, signal is continuously amplified and reference voltage is ceaselessly reduced till they approach to each other within the given limit. Through this method, accurate measurement is available.
