Abstract

The utility model relates to a vehicular GPS navigation early warning device, comprising a GPS satellite communication module, a first microprocessor, a second microprocessor, a data storing module which stores early-warning-required road section information, a display screen, an input module and an alarm module. The GPS satellite communication module receives a satellite positioning signal, converts the signal into the longitude coordinates and latitude coordinates of the current position, and then transfers the coordinate information to the first microprocessor and the second microprocessor. The first microprocessor determines the best travel way and controls the alarm module to send prompt about travel directions along the way. The second microprocessor compares the current longitude coordinates and latitude coordinates of the vehicle, which are received by the GPS satellite communication module with the longitude coordinates and the latitude coordinates of the early-warning-required road section, which are stored in the data storing module; when the target is approached, an early warning alarm is sent in advance via the alarm module. The device is not only capable of realizing GPS navigation guiding function, but also capable of sending early warning alarms at early-warning-required road sections, thereby largely reducing the possibility of driving violation by drivers.
