Title:
SENSOR DEVICE AND METHOD FOR WIRELESS DETECTION OF PARKING
Document Type and Number:
WIPO Patent Application WO/2017/217629
Kind Code:
A1
Abstract:
The present invention relates to a sensor device (100) for a wireless detection of parking used to wirelessly detect the entry of a vehicle, the sensor device (100) for the wireless detection of parking comprising: a proximity sensor (110) for generating a trigger signal upon detecting a vehicle approaching within a first detection distance; an RF radar (120) for detecting a vehicle approaching within a second detection distance (the first detection distance > the second detection distance) by switching from a sleep mode to a wakeup mode in response to the trigger signal of the proximity sensor (110); and a communication module (130) for transmitting a detection signal when the RF radar (120) detects a vehicle. As the present invention uses an RF radar, it is possible to normally detect the entry of a vehicle without error even when the surface of the RF radar is contaminated or covered with foreign substances such as snow, etc. and reduce power consumption by means of the RF radar normally being on standby in sleep mode, which is a power saving mode, and then switching to a wakeup mode when a vehicle is detected by the proximity sensor, and thereby detecting a vehicle approaching.
