Abstract
The invention relates to a ranging method, in particular to an ultrasonic wave-based mobile ranging method, which belongs to the technical field of communication. The ultrasonic wave-based mobile ranging method is characterized in that: an ultrasonic wave emitter first emits a beam of ultrasonic waves to a certain direction, and the ultrasonic waves are reflected back when meeting a barrier; after the ultrasonic waves are detected by a detector, a timer calculates the time which the ultrasonic waves take to return after being emitted; a software is utilized to work out the distance (the speed of the ultrasonic waves is known under certain medium), and the distance is displayed on a liquid crystal display. After the method is adopted, the measuring instruments cannot be affected by the measured medium, the difficulty of scientific research is reduced, the cost of scientific research is reduced, the utilization of ultrasonic wave detection is rapid and convenient, moreover, calculation is simple, miniaturization and integration are easy, and the ultrasonic wave-based mobile ranging method can meet the requirement of industrial applicability in terms of measurement, and has a broad development prospect.
