The navigation information transmitting system at least consists of the vehicle-mounted module (1) which is internally provided with a satellite positioning module and a GSM (Global System for Mobile Communications) /GPRS (General Packet Radio Service) or 3G communication module, a satellite positioning group (2), a system data center (3) and a mobile communication base station (4). By calculating data of position, time, speed, direction and the like of a vehicle reaching an indicated POI (Point of Interest), the traffic status at each moment can be calculated, transmitted to the vehicle-mounted module as navigation information, and displayed through a display device to realize real-time traffic status navigation.
Description
Technical field
The present invention relates to a kind of vehicle module navigation information transmission system and sending method utilized, by calculating the data such as the position of vehicle when marching to the point of interest POI that indicates, time, speed, direction, calculate each condition of road surface constantly, and it is sent to vehicle as navigation information shows, belong to the electronic navigation system field.
Background technology
When current vehicle-mounted monitoring and navigator, mobile unit send gps data to system, substantially all be to arrange according to the time interval, such as sending once every 30 seconds or 5 seconds.This is usually so that we are difficult to this time interval that arranges of the science that compares.If the interval is excessive, can cause then that the vehicle travel distance is too far away in the meantime, the data of transmission are not accurate enough and timely; On the contrary, if interval too small, the situation that can cause again equipment overspending data traffic, consumes too much power supply.
Summary of the invention
Purpose of design: avoid the weak point in the background technology, design and a kind ofly both can save data traffic and electrical source consumption, also can be more successful finish the target of obtaining the real-time traffic navigation information.
Design proposal: in order to realize above-mentioned purpose of design.The method and system that the navigation information of the present invention's design sends, it is characterized in that at least by the vehicle module that is built-in with satellite positioning module and GSM/GPRS or 3G communication module, the satnav group, system data center and mobile communication base station consist of, GPS module in the vehicle module obtains the locating information of vehicle arrangement by the gps satellite group, and be sent to the system data center, pass through the mobile communication platform communication between system data center and the vehicle module, vehicle module passes to the system data center with the data of record, the storage data then are responsible at the system data center, and carry out correlation computations according to the request of vehicle module, result of calculation then returns to vehicle module by mobile communication platform.
Described vehicle module comprise processor, wireless communication module, satellite positioning module, power circuit, display screen, module; Power circuit is to each module for power supply, processor and wireless communication module bidirectional data communication, processor receive from satellite positioning module, the data message of module, processor signal output termination display screen signal input end.
Technical scheme 1: a kind of navigation information transmission system, comprise by the vehicle module that is built-in with satellite positioning module and GSM/GPRS or 3G communication module, the satnav group, system data center and mobile communication base station, the GPS module obtains the locating information of vehicle arrangement in the vehicle module by the gps satellite group, and be sent to the system data center, pass through the mobile communication platform communication between system data center and the vehicle module, vehicle module passes to the system data center with the data of record, the storage data then are responsible at the system data center, and carry out vehicle navigation information according to the request of vehicle module and calculate, navigation information result of calculation then returns to vehicle module by mobile communication platform.
Technical scheme 2: a kind of navigation information sending method is that the sectional type navigation information sends in the method, and concrete grammar is as follows:
(1) in the map datum that in the ground module, stores, indicated the English full name Point of a lot of point of interest POI(of Interest), these points of interest POI, such as traffic-control device, bus stop, railway station etc., can be to Vehicle Driving Cycle, especially taxi is sought business and is produced obviously impact;
(2) system is provided with the GPS fence for each POI that indicates, triggers GPS fence condition when vehicle marches to the position of these POI, and vehicle module sends information to the system data center;
(3) according to above method, each bar road is considered, the system data center is in the identical moment, the information such as the speed of crossing, traffic lights and other POI in all these road processes of vehicles process, Real-time Traffic Information, the full zero load of taxi are carried out analytical calculation, can know whole road congestion conditions.The result that the system data center will draw again is sent to vehicle module, shows at display screen, as the information of real-time road navigation;
(4) above method, vehicle module need not every frequent transmission information of several seconds to the system data center, and just in ability transmitted signal when needing the POI point of record, have saved data traffic, also can finish the target of obtaining the real-time traffic navigation information.
The present invention compares with background technology, not the transmission data of controlling merely vehicle module according to the time interval, but by the POI point that condition of road surface is had a significant effect is set, only send data in these positions, technical ability guarantees in time to obtain important data, again can be because of too small continuous transmission data of the time interval, waste mass data flow and electrical source consumption.
