Detailed description of the invention
A kind of call onboard navigation system of recognizable Quick Response Code, including: GPS module: the small-sized dress being installed on vehiclePut, be a part for GPS board units, be used for receiving the information that satellite is transmitted；Wireless communication module: generally use vehicle-mounted nothingLine phone, radio station or mobile data terminal (MDT) are to complete information interactive function；Alarm control module: to Surveillance center's networkSend alarm signal, circulate a notice of vehicle abnormality information speech control module: complete the function such as sound control and service；Display module:It is used for showing the video image informations such as position road conditions, can be selected for LCD, CRT or TV and show PC module: integration processes each functional module,Coordinate corresponding software, complete to specify function, as carried out data process, calculate the longitude of position, latitude, height above sea level, speedDegree and time etc.；Electric map module: storing very abundant city map, the network of highways figure in the whole nation, additionally, typically also storeThere are the information such as gas station, convenience store, government bodies, tourist attractions, restaurant, parking lot；Self-contained navigation module: work as running carWhen catching less than gps satellite signal at the cover materials such as subterranean tunnel, high-story group of buildings, highway, system is automatically imported certainlyRule navigation system；Map-matching module: the automobile position that measured by GPS satellite navigation and self-contained navigation system, direction of advanceAll there is certain error with the route track of actual travel, be 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 described excess oil amount isNo less than presetting oil mass threshold values, or whether described vehicle continuation of the journey distance is less than presetting distance threshold values；If described excess oil amount is less than pre-If oil mass threshold values, or described vehicle continuation of the journey distance is less than presetting distance threshold values, then search for gas station by onboard navigation system,Car phone module, this car phone module comprises a bluetooth module, realizes car phone module and mobile phone by bluetooth moduleRealize communication.
The call onboard navigation system of described recognizable Quick Response Code also includes vehicle mounted guidance entertainment systems part, WiFi roadBy module and wireless communication module, WiFi routing module and wireless communication module are connected to vehicle mounted guidance entertainment systems partOn;Described onboard navigation system also includes gathering the control display floater that the photographic head of Quick Response Code is connected with described GPS module,And the first communication interface being connected with described GPS module；The signal output part of described photographic head and the second communication interface connect,Described second communication interface is adaptive with described first communication interface, and the signal output part of described photographic head passes sequentially through described secondCommunication interface and described first communication interface are connected with described GPS module.
The information data transmission of described GPS module has procedure below: open the function of Bluetooth communication of onboard navigation system,And it is set up radio communication with the mobile phone in car be connected；The GPS function utilizing onboard navigation system obtains GPS information data,And described GPS information data will be sent to mobile phone by radio communication；The Bluetooth of mobile phone communication module on mobile phone is used to obtainDescribed GPS information data, and utilize described GPS information data to carry out location positioning.
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 consumptionLow, disposal ability is strong, simple and convenient.Use embedded OS more for vehicle-mounted PC, such as WINDOWSCE and embeddedLINUX etc..The frequency used according to vehicle and the requirement of the complexity of road, it reliability must want height, and autgmentabilityTo get well with compatibility.
GPS technology utilized gps satellite signal to receive, and can receive the data ginseng that satellite sends incessantly with 24 hoursNumber clears out the three-dimensional position of reception, three-dimensional and movement velocity and temporal information.Automatic navigator is to be defended by acceptanceStar signal, coordinates electronic map data, grasps oneself orientation and destination in good time, and the pattern of independent navigation does not collect any makingBy expense, user can selectively buy map datum according to the needs of oneself.When user is installed vehicle GPS onboardAfter, 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 eyeA 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 regulationsMake；Machine uses first three communications centre about 10 hours, allows battery power reservoir capacity significantly play；First start up the car, then insert cigar lighterPower supply.Cigar lighter is pulled out in navigation end, plugs again, be so conducive to protecting battery after starting up the car next time.
The call onboard navigation system of a kind of recognizable Quick Response Code of the present invention so that route or travel by vehicle can be the fastestSpeed location, anti-theft feature is the most powerful, and the basic security preferably protecting vehicle also provides good road to driverLine services；WiFi can be provided by 3G gateway to other people on car while completing auto navigation and automobile entertainmentOnline, can be while completing auto navigation and automobile entertainment, providing on WiFi to other people on car by 3G gatewayNet;By onboard navigation system search near gas station, select to go to gas station to group refueling for user, reduce vehicleStop at the risk of halfway.
