【Abstract】 A new method for ultrasonic distance measurement based on ultrasonic circulation and multi pulse echo principle is presented in the paper. The ultrasonic distance measurement system based on the single chip microcomputer is given. This method can conquer the limitation of pulse echo times and improve the accuracy of measurement after temperature compensation.更多还原
