Abstract
The invention relates to a technology of vehicle-mounted device positioning and discloses a vehicle-mounted-device position calibration method based on Beidou positioning and 3G positioning. In the method, auxiliary calibration of the position of a vehicle-mounted device is carried out under a condition that blind areas occur or signals are poor in Beidou positioning. The method includes the following steps: a. the vehicle-mounted device acquiring 3G base-station information of a position which a vehicle is at through a network module; b. the vehicle-mounted device sending the 3G base-station information to a vehicle-mounted service platform; c. the vehicle-mounted service platform analyzing the 3G base-station information and acquiring corresponding longitude and latitude information of a 3G base station; d. the vehicle-mounted service platform sending the longitude and latitude information to the vehicle-mounted device; e. the vehicle-mounted device carrying out auxiliary calibration on information of the position which the vehicle is at according to the longitude and latitude information. The vehicle-mounted-device position calibration method based on the Beidou positioning and the 3G positioning is applicable to auxiliary positioning of the vehicle-mounted device.
Description
Technical field
The present invention relates to the technology to mobile unit location, specifically, relate to a kind of mobile unit position calibration method based on Big Dipper location and 3G location.
Background technology
Mobile unit is more and more used on automobile, the mobile unit of main flow has been installed positioning chip-Big Dipper positioning chip, as domestic first positioning system, civil nature formally starts, the mobile unit of embedded wince system has also more been used the mixed-media network modules mixed-media of 3G, in conjunction with vehicle-mounted service platform, carries out location management service.In the region of most outdoor spaciousness Big Dipper location, can accurately locate, but some blind spot or indoor, and Big Dipper weak output signal or there is no signal, will rely on the architecture of 3g network.Rely on both location to coordinate, can well determine and the accurate location at mobile unit place position is uploaded to service platform, carry out position of platform Service Management.
Vehicle-mounted service platform is a megatrend of Automobile Electronic Industry development, but the position of service platform more relies on the positional information that terminal device is uploaded, if the positional information of the positional information of uploading peace you is not mated, or the positional information of uploading is inaccurate, positional information calibration is exactly that a helpdesk end accurately calculates the approach of current mobile unit position so.
Summary of the invention
Technical matters to be solved by this invention is: propose a kind of mobile unit position calibration method based on Big Dipper location and 3G location, the in the situation that of there is blind area or signal difference, assisted calibration is carried out in the position of mobile unit in Big Dipper location.
The present invention solves the problems of the technologies described above adopted technical scheme:
A mobile unit position calibration method based on Big Dipper location and 3G location, comprises the following steps:
A. mobile unit obtains the NodeB information of vehicle position by mixed-media network modules mixed-media;
B. mobile unit sends to vehicle-mounted service platform by described NodeB information;
C. vehicle-mounted service platform is resolved described NodeB information, obtains the latitude and longitude information that this NodeB is corresponding;
D. vehicle-mounted service platform is issued to described mobile unit by this latitude and longitude information;
E. described mobile unit is according to this latitude and longitude information assisted calibration vehicle position information.
Further, mixed-media network modules mixed-media described in step a is 3G SIM card module.
The invention has the beneficial effects as follows: according to vehicle-mounted service platform, have powerful computing function and obtain the advantage of data, the base station information that mobile unit is uploaded is resolved, be translated as more accurately the Big Dipper latitude and longitude information in corresponding place, be handed down to again mobile unit, to realize the accurate location in situation a little less than without Big Dipper signal or pickup electrode.
Accompanying drawing explanation
Fig. 1 is the process flow diagram of the mobile unit position calibration method in the present invention.
Embodiment
The present invention is intended to propose a kind of mobile unit position calibration method based on Big Dipper location and 3G location, the in the situation that of there is blind area or signal difference, assisted calibration is carried out in the position of mobile unit in Big Dipper location.It realizes principle: according to vehicle-mounted service platform, have powerful computing function and obtain the advantage of data, the base station information that mobile unit is uploaded is resolved, be translated as more accurately the Big Dipper latitude and longitude information in corresponding place, be handed down to again mobile unit, to realize the accurate location in situation a little less than without Big Dipper signal or pickup electrode.
On concrete enforcement, first require mobile unit to possess communication basic capacity, by configuration 3G or 2G SIM card module, can obtain the base station relevant location information data of the vehicle position that operator provides, data are sent in to Platform Server, by the powerful back-office support ability of platform, parse base station position information, obtain corresponding latitude and longitude information, the latitude and longitude information of obtaining is handed down to mobile unit in order to calibrate vehicle location, can realize the location assisted calibration function in Big Dipper no-fix situation or the in the situation that location occurs skew, and can improve locating speed, reach rapid positioned vehicle position, obtain the ability of positional information, for the commercialization of vehicle-mounted Big Dipper location and promote the use all very favourable.
Referring to Fig. 1, the flow process of the mobile unit position calibration method in the present invention comprises following implementation step:
1. mobile unit obtains the NodeB information of vehicle position by mixed-media network modules mixed-media;
2. mobile unit sends to vehicle-mounted service platform by described NodeB information;
3. vehicle-mounted service platform is resolved described NodeB information, obtains the latitude and longitude information that this NodeB is corresponding;
4. vehicle-mounted service platform is issued to described mobile unit by this latitude and longitude information;
5. described in, mobile unit is according to this latitude and longitude information assisted calibration vehicle position information.
Enforcement by said method can improve the accuracy of vehicle location greatly, and can reduce the screening of the data that platform pair warp and weft degree deviation is larger, does not need by traditional complicated algorithm judgement invalid data, thereby improves platform data accuracy and validity.And can make the spending of platform and terminal lower, speed is faster.
