Title:
BEIDOU NAVIGATION SYSTEM BASED VEHICLE-MOUNTED INTELIGENT TERMINAL
Document Type and Number:
WIPO Patent Application WO/2020/037912
Kind Code:
A1
Abstract:
The present invention relates to the technical field of vehicle-mounted intelligent terminals for automobiles and in particular relates to a Beidou navigation system-based vehicle-mounted intelligent terminal, comprising: a terminal power supply, a power supply management module and a central controller; the central controller is electrically connected by a signal line with an enable signal end of the power supply management module; and the power supply management module is electrically connected by a power supply line with a movement sensing module, a Beidou navigation module, a bluetooth module, a 4G module and a CAN port module, respectively. According to the Beidou navigation system-based vehicle-mounted intelligent terminal, when the central controller does not output the enable signal, the demands of the vehicle-mounted intelligent terminal for static currents can be completely satisfied, thereby solving the problem of high static power consumption of the controller; when the central controller outputs the enable signal, due to a high switching frequency of a DCDC power conversion chip, the power conversion efficiency is high.
