Vehicle-mounted satellite positioning navigation system

Abstract

The invention discloses a vehicle-mounted satellite positioning navigation system which comprises a central processing unit, an automotive anti-theft module, a map navigation module, a satellite positioning module, a power supply and power-saving control module, a wired data exchange interface, a working indication lamp, an alarm conformation lamp, a voice control module, a display module, a communication network module, a GPS receiver and a GPS antenna. The automotive anti-theft module, the map navigation module, the satellite positioning module, the power supply and power-saving control module, the wired data exchange interface, the working indication lamp, the alarm conformation lamp, the voice control module, the display module, the communication network module, the GPS receiver and the GPS antenna are all connected with the central processing unit. The vehicle-mounted satellite positioning navigation system is simple in structure and convenient to use, the problem of signal drift during vehicle-mounted navigation can be solved through the GPS receiver, traffic condition information of all road sections can be effectively obtained in real time, route selection of vehicle-mounted navigation is more reasonable, congested road sections are effectively avoided, accordingly traffic congestion is relieved, and the time required by a driver is saved.

Description

technical field [0001] The invention relates to the technical field of automotive electronic equipment, in particular to a vehicle-mounted satellite positioning and navigation system. Background technique [0002] In recent years, with the continuous advancement of automobile technology, car navigation systems, as high value-added electronic products, account for an increasing proportion in cars. Car multimedia navigation can first optimize traffic efficiency. After the popularization of GPS navigation, it will bring It is a smarter, more scientific and more efficient traffic management system, which relieves the traffic pressure in the city to a large extent. [0003] Secondly, with the rapid development of my country's economy, urban roads are changing frequently. Although the current vehicle multimedia system has navigation functions, it cannot grasp the road changes in time and help drivers design the best, fastest and most economical driving route. , to improve driving ...
