First embodiment
As shown in figure 1, first embodiment of the invention provides a kind of compensation method of vehicle driving trace, methods described includes
Step：
S11, obtain the code stream information that GPS reports.
In the present embodiment, the GPS include global position system GPS, GLONASS GLONASS,
Galileo satellite navigation system GSNS and Beidou satellite navigation system BDS.
S12, the code stream information reported to the GPS decode, and obtain the current azimuth of vehicle
Information.
As illustratively, by taking global position system GPS as an example, NMEA (National Marine that GPS is reported
Electronics Association, National Marine Electronics association) in code stream, wrapped in GPRMC (recommendation location information) item
The azimuth information of current driving is contained, has been decoded by the NMEA code streams reported to GPS, you can it is current to obtain the vehicle
Azimuth information.GLONASS GLONASS, galileo satellite navigation system GSNS and Beidou satellite navigation system BDS with it is such
As, therefore not to repeat here.
If the current azimuth of S13, vehicle is higher than pre-configured orientation angle, the position of the GPS is believed
Breath reports frequency to report frequency to adjust to second from first to report frequency.
In the present embodiment, described second frequency is reported to report frequency more than described first.
In the present embodiment, pre-configured orientation angle can be voluntarily configured by user, can be obtained according to different values is set
Different compensation precisions.
Still by taking global position system GPS as an example, decoded by the NMEA code streams reported to GPS, obtain the vehicle
After current azimuth information, can determine whether out vehicle is to be in turn condition.When vehicle is to be in straight travel state,
Report a GPS position information within every 15 seconds, the time interval reported is more relatively long, and vehicle can be learnt by smooth line
Driving trace.But turn condition is in vehicle, if still reporting a GPS position information, smooth line with every 15 seconds
Cannot actual response go out the trace information of vehicle.Therefore, after using the present embodiment, if it is determined that out vehicle is to be in
Turn condition, then a GPS position information was reported with every 3 seconds, that is, improve and report frequency.
It refer to shown in Fig. 2, in one embodiment, if the current azimuth of the vehicle is higher than pre-configured orientation angle,
Then the positional information of the GPS is reported frequency to report frequency to adjust to second from first to report frequency
Also include step afterwards：
The warning information that S14, the reception server are sent, the global navigation satellite is adjusted according to the warning information received
System reports frequency to report frequency to the 3rd.
In this embodiment, the described 3rd report frequency to report frequency more than described first and frequency is reported less than second
Rate.
As previously described, if it is determined that out vehicle is to be in turn condition, then a GPS location letter was reported with every 3 seconds
Breath, that is, improve and report frequency.But be not to report frequency higher, performance is better.The increase of frequency is reported, can no doubt be increased
Add GPS position information point, trace information is more smooth, but the information thing for reporting the increase of frequency that server can be caused to receive
Part frequency increases.And corresponding to server it is the vehicle individual of magnanimity, if reporting frequency too high, can not only to report thing
Part queue event of joining the team is too fast, can also increase the pressure of server process event, and extreme case may result in server and delay machine.
Therefore, in this embodiment, by the warning information obtained or the reception server is sent, adjust in time
Frequency is reported, on the one hand contributes to reduce the pressure of server process event, on the other hand reduces GPS and report frequency, money can be saved
Source.
In one embodiment, if the current azimuth of the vehicle is higher than pre-configured orientation angle, the whole world is defended
The positional information of star navigation system reports frequency to report frequency to adjust to second to report and also include step after frequency from first：
Retrieve the current azimuth information of vehicle；
If the current azimuth of vehicle is less than pre-configured orientation angle, the positional information of the GPS is adjusted
Report frequency to report frequency to first.
In this embodiment, by judging whether vehicle enters straight-line travelling again, and global navigation satellite system is adjusted
The positional information of system reports frequency, helps to reduce the pressure of server process event, reduces GPS and report frequency, can save
Resource.
In another embodiment, if the current azimuth of the vehicle is higher than pre-configured orientation angle, by the whole world
The positional information of satellite navigation system reports frequency to report frequency to adjust to second to report and also include step after frequency from first
Suddenly：
The positional information of upload is shown on map, the location point that each positional information is shown on map connects
Pick up to form movement locus.
In this embodiment, methods described also includes step：
The movement locus is compared with the road net data in GPS navigation data, will be with road network
The location point of the inconsistent positional information of data automatic fitration Null Spot position, forms new movement locus as Null Spot position.
In this embodiment, according to the historical track in the short time, automatic fitration Null Spot position, in the M of have collected over
After N bars point position information in second, with reference to the road net data in its track and GPS navigation data, automatically analyze
Null Spot position is filtered, the point position for ensureing to upload all is available point position, improves the accuracy of track of vehicle monitoring.
When the quantity of monitoring objective is changed into magnanimity from single, monitors magnanimity target in real time, Null Spot position is visually non-
Chang Rongyi forms interference, and in the research carried out to magnanimity historical track, when filtering Null Spot position often consumes substantial amounts of
Between and amount of calculation.Present embodiment has used for reference the thought of Distributed Calculation, and its track is combined during the data of bleeding point position
With the road net data in GPS navigation data, filtering Null Spot position is automatically analyzed, ensures the point position uploaded all
It is available point position, eliminates Null Spot position at once, the application after being substantially increases efficiency.
For further explaination the present embodiment, now it is described in detail by taking global position system GPS as an example：
For vehicle in straight-line travelling, global position system GPS reports a GPS position information in every 15 seconds.
In real time, the code stream information that global position system GPS reports, and the code reported to global position system GPS are obtained
Stream information is decoded, and obtains the current azimuth information of vehicle.If if the current azimuth of vehicle is higher than 5 degree, by the whole world
The positional information of position system GPS reports frequency, reported a GPS position information to adjust to every 3 seconds from every 15 seconds and reports one
Secondary GPS position information.
If after this, judging that vehicle enters straight-line travelling again by azimuth information, then return on every 15 seconds
Report a GPS position information.
If receiving the warning information of server transmission, the positional information of global position system GPS is reported into frequency
Rate, reported a GPS position information to adjust to every 10 seconds from every 3 seconds and report a GPS position information.
The compensation method of vehicle driving trace provided in an embodiment of the present invention, the current azimuth of vehicle is obtained by decoding
Information, if the current azimuth of vehicle is higher than pre-configured orientation angle, the positional information for improving GPS reports
Frequency；It is during turning to solve solution vehicle, and the time interval that positional information reports is longer, and line is unable to actual response
The problem of going out the trace information of vehicle；Improve Consumer's Experience.
