ULTRASONIC DISTANCE MEASURING SYSTEM AND ULTRASONIC DISTANCE MEASURING METHOD

摘要

An ultrasonic distance measuring system and an ultrasonic distance measuring method that can perform a distance measurement by use of a simple apparatus structure and particularly can precisely measure the distance between a transmitting node and a receiving node in a short time by use of only ultrasonic waves. In the ultrasonic distance measuring system (100), the transmitting node (102), which generates a communication packet and transmits the communication packet by use of ultrasonic waves, is connected to the receiving node (104), which receives the communication packet to measure the distance between the receiving node and the transmitting node, via an Internet communication network (106) such that they can wirelessly communicate with each other.
