Speed calibration ranging system based on STC89c52 single-chip microcomputer
Abstract:Calibration ranging system, the speed of the ultrasonic ranging based on STC89c52 single-chip processor is widely used in today's ranging system, so the measurement accuracy is very important, in order to enhance the influence of temperature on the acoustic wave velocity before many scholars put forward the method of temperature compensation, but different geographical location and environmental acoustic propagation velocity is different, this paper proposes a correct velocity method to improve the ranging accuracy, the experimental results show that this method is effective.
