Problems solved by technology

The geomagnetic sensor is susceptible to interference from magnetic fields around the vehicle
The ultrasonic radar is easily affected by leaves and dust, and the RFID detector needs to be equipped with a radio frequency tag on the vehicle to be detected, and the power consumption of the RFID detector is relatively high
In this way, the detection of the parking space state will be inaccurate

Abstract

The invention discloses a positioning system, a positioning method and a road sticker. The road sticker comprises a shell, and further comprises a geomagnetic sensor arranged in the shell; an ultrasonic radar arranged in the shell; a power module arranged in the shell and used for supplying power to the road sticker; a wireless communication module arranged in the shell and used for providing wireless network communication for the road sticker; and a micro-controller arranged in the shell, electrically connected with the geomagnetic sensor, the ultrasonic radar, the power module and the wireless communication module, and used for determining the state of a parking space according to data sensed by the geomagnetic sensor and the ultrasonic radar and transmitting the state of the parking space through a wireless network. The invention also provides a positioning system and a positioning method, which can improve the accuracy of parking space state detection.

Description

technical field [0001] The invention relates to the field of positioning, in particular to a positioning system, a positioning method and road stickers. Background technique [0002] At present, the detection of parking space status is widely used in closed parking lots and on-street parking facilities. The parking space detectors used in the detection of the parking space state can be divided into three categories, namely geomagnetic sensors, ultrasonic radars, and RFID detectors. The geomagnetic sensor is susceptible to interference from magnetic fields around the vehicle. The ultrasonic radar is easily affected by leaves and dust, the RFID detector needs to be equipped with a radio frequency tag on the vehicle to be detected, and the power consumption of the RFID detector is relatively high. In this way, the detection of the parking space state will be inaccurate. Contents of the invention [0003] In view of this, it is necessary to provide a positioning system, a p...
