Problems solved by technology

[0002] The vehicle positioning information system is an interrelated information exchange system with the goal of determining the spatial position. Simply put, it is a satellite system composed of multiple satellites covering the whole world. Four satellites can be observed at any point at the same time to ensure that the satellite can collect the latitude, longitude and altitude of the observation point, so as to realize navigation, positioning, timing and other functions, and to guide the vehicle to accurately follow the selected route and arrive on time Destination; most of the existing vehicle positioning information systems use the GPS positioning system, but the GPS is in an urban area full of tall buildings, and the satellite signals are easily blocked, resulting in inaccurate positioning, and the existing vehicle positioning information systems cannot monitor their own location in real time. Operational conditions, there are often errors in navigation deviation

Abstract

The invention provides a vehicle positioning system information, which comprises a main controller module, a GPS positioning module, a Beidou satellite positioning module, a self-test chip module, a power supply module, a display screen module, an audio output module, an interface module and a driving record camera module. The GPS positioning module and the Beidou satellite positioning module are connected to a data interface of the main controller module. A control interface of the main controller module is connected with the display screen module and the audio output module. The self-test chip module is connected with the main controller module. The power supply module is connected to a power supply interface of the main controller module. An interface module is further disposed on the main controller module. The driving record camera module is connected to the main controller module. The beneficial effects of the invention are that the vehicle positioning information system can combine GPS positioning and Beidou satellite positioning, is accurate in positioning, with continuous satellite positioning signals, can perform self-test and is accurate in navigation.
