ULTRASONIC SENSOR BASED ON NETWORK

摘要

Network-based ultrasonic sensors are provided to enable an external(upper) apparatus to change setup values inside the sensors freely through a communication unit according to a distance between the sensors and a detected object and movement of the detected object, thus exact and effective sensing can be available as enabling a user to monitor data sensed by the sensors in real time even at a remote place. A server(300) transmits data such as measurement reference setup values for a measurement target of ultrasonic sensors(200) or operation commands to the more than one ultrasonic sensor(200) which forms a network(210). The respective ultrasonic sensors(200) are designated with intrinsic addresses, so that the server(300) designates desired intrinsic addresses to transmit the addresses to the sensors(200) together with desired data.
