Technical scheme has the advantages that

A kind of onboard navigation system of the present invention so that route or travel by vehicle can the most quickly position, and anti-theft feature is the strongest Greatly, the basic security preferably protecting vehicle also provides good route service to driver；By photographic head by ground Location information transmission, to automatic navigator, reduces and automatic navigator and wireless terminal is driven compatible requirement, improve use Family is experienced;By onboard navigation system search near gas station, select to go to gas station to group refueling for user, reduce Vehicle stops at the risk of halfway.

Detailed description of the invention

A kind of onboard navigation system, including: GPS module: the midget plant being installed on vehicle, is GPS board units A part, is used for receiving the information that satellite is transmitted；Wireless communication module: generally use onboard wireless phone, radio station or movement Data terminal (MDT) is to complete information interactive function；Alarm control module: send alarm signal to Surveillance center's network, circular Vehicle abnormality information speech control module: complete the function such as sound control and service；Display module: be used for showing position road conditions etc. Video image information, can be selected for LCD, CRT or TV and shows PC module: integration processes each functional module, coordinates corresponding software, completes Specify function, as carried out data process, calculate the longitude of position, latitude, height above sea level, speed and time etc.；Electronic chart Module: store very abundant city map, the network of highways figure in the whole nation, additionally, typically also store gas station, convenience store, The information such as government bodies, tourist attractions, restaurant, parking lot；Self-contained navigation module: when running car to subterranean tunnel, high-rise building When catching less than gps satellite signal at the cover materials such as group, highway, system is automatically imported self-contained navigation system；Map Join module: the automobile position that measured by GPS satellite navigation and self-contained navigation system, direction of advance all with the route of actual travel There is certain error in track, is accomplished by using map matching technology to revise these errors;Oiling prompting module: obtain The excess oil amount of vehicle, and calculate vehicle continuation of the journey distance according to average fuel consumption；Judge that whether described excess oil amount is less than presetting oil mass valve Value, or whether described vehicle continuation of the journey distance is less than presetting distance threshold values；If described excess oil amount is less than presetting oil mass threshold values, or described Vehicle continuation of the journey distance less than presetting distance threshold values, then searches for gas station by onboard navigation system.

Described onboard navigation system also includes that the control that the photographic head of collection Quick Response Code is connected with described GPS module shows Panel, and the first communication interface being connected with described GPS module；The signal output part of described photographic head and the second communication interface Connecting, described second communication interface is adaptive with described first communication interface, and the signal output part of described photographic head passes sequentially through institute State the second communication interface and described first communication interface is connected with described GPS module.

Owing to using the particularity of environment, the necessary volume as the vehicle-mounted PC of the system core is little, and integrated level is high, power consumption Low, disposal ability is strong, simple and convenient.Use embedded OS more for vehicle-mounted PC, such as WINDOWSCE and embedded LINUX etc..The frequency used according to vehicle and the requirement of the complexity of road, it reliability must want height, and autgmentability To get well with compatibility.

GPS technology utilized gps satellite signal to receive, and can receive the data ginseng that satellite sends incessantly with 24 hours Number clears out the three-dimensional position of reception, three-dimensional and movement velocity and temporal information.Automatic navigator is to be defended by acceptance Star signal, coordinates electronic map data, grasps oneself orientation and destination in good time, and the pattern of independent navigation does not collect any making By expense, user can selectively buy map datum according to the needs of oneself.When user is installed vehicle GPS onboard After, no matter user is in which city, cities and towns or suburb, and we can find a restaurant or recently in the twinkle of an eye A gas station.Thus greatly facilitate our trip.

During use, first close the page and close machine below again, it is impossible to be not related to the page and the most directly shut down, be exactly otherwise to grasp in violation of rules and regulations Make；Machine uses first three communications centre about 10 hours, allows battery power reservoir capacity significantly play；First start up the car, then insert cigar lighter Power supply.Cigar lighter is pulled out in navigation end, plugs again, be so conducive to protecting battery after starting up the car next time.

A kind of onboard navigation system of the present invention so that route or travel by vehicle can the most quickly position, and anti-theft feature is non- Chang Qiang great, the basic security preferably protecting vehicle also provides good route service to driver；Pass through photographic head By address information transmission to automatic navigator, reduce and automatic navigator and wireless terminal are driven compatible requirement, improve Consumer's Experience;By onboard navigation system search near gas station, for user select go gas station to group refueling, Reduce vehicle and stop at the risk of halfway.

Finally it is noted that the foregoing is only the preferred embodiments of the present invention, it is not limited to the present invention, although Being described in detail the present invention with reference to previous embodiment, for a person skilled in the art, it still can be right Technical scheme described in foregoing embodiments is modified, or wherein portion of techniques feature is carried out equivalent.All Within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included in the protection of the present invention Within the scope of.
