Miniaturized vehicle body positioning system

Abstract

The invention relates to a miniaturized vehicle body positioning system which comprises a substrate, a system basic chip, a Bluetooth low-power-consumption chip, an ultra-wideband chip, a Bluetooth antenna group and an ultra-wideband antenna group. The system basic chip is used for providing power management and controller local area network communication. The Bluetooth low-power-consumption chip is used for receiving and transmitting a Bluetooth wireless signal. And the ultra-wideband chip is used for performing distance measurement positioning and data processing, and performing data transmission with the system basic chip and the Bluetooth low-power-consumption chip through a plurality of serial peripheral interface signals. The Bluetooth antenna group comprises a first Bluetooth antenna and a second Bluetooth antenna which are arranged on the substrate. The ultra-wide-band antenna group comprises a first ultra-wide-band antenna and a second ultra-wide-band antenna, the first ultra-wide-band antenna and the second ultra-wide-band antenna are respectively inserted into the substrate so as to be connected to the ultra-wide-band chip, and the extending direction of the ultra-wide-band antenna group intersects with the plane of the substrate. According to the invention, the vehicle body space occupation of the vehicle body positioning system can be reduced, and the signal receiving and transmitting capability can be improved.
