Section, every scheme that tracing point can be screened and rejected extremely, as long as meeting the technology of the present invention principle category, is belonged to
In protection scope of the present invention.
Emphasis commerial vehicle is the object of key monitoring in itself, for example, the national emphasis commerial vehicle connection that Ministry of Communications establishes
In net joint control system, real-time monitoring just has been carried out to the emphasis commerial vehicle of all parts of the country.The present embodiment can supplement real-time prison
There is monitoring exception during data exception in control, is supported so as to provide data for platform monitoring.
Fig. 1 is that emphasis commerial vehicle exception tracing point rejects flow chart in the embodiment of the present invention one.As shown in figure 1, this is heavy
Point commerial vehicle exception tracing point is rejected flow and comprised the following steps：
Step 101, the geographical position according to the tracing point of emphasis commerial vehicle, geographical position is located at outside preset range
The tracing point is rejected.
As a rule, the tracing point of emphasis commerial vehicle is both present on the travel route of emphasis commerial vehicle, every inclined
Tracing point from route can consider there occurs exception, be abnormal tracing point.Judgement for abnormal tracing point, primary is
The tracing point of the geography fence of emphasis commerial vehicle entirety operation area is first eliminated.
For example, emphasis commerial vehicle is only run in some administrative region, but this administrative region has been pointed out in some track
Geographic range, then the tracing point is abnormal tracing point.Or other tracks for having deviated considerably from normal operation route scope
Point, and need what is rejected.
Specifically, can be according to the geographical location information in each tracing point, by the geographical location information with setting in advance
Fixed geographic range is made comparisons, if not in geographic range set in advance, then needs to reject the tracing point.
Usual geographical position is represented with longitude and latitude, then needs to be respectively compared the longitude of tracing point and latitude,
Any one has gone out normal geographic range set in advance for longitude and latitude, then the tracing point needs to reject.For example, there is latitude
Degree is zero or the information of south latitude, then illustrates mistake necessarily occur, abnormal tracing point is, it is necessary to reject.
Here the delimitation of geographic range, the operation route of emphasis commerial vehicle and possible geographical model are referred to
Enclose, the scope can also be slightly larger than.The scheme of setting geography fence can generally be used by delimiting the method for geographic range, can also
Using the scheme delimited one by one along road.Specific preset range can set and adjust as needed.

The obvious velocity information of unreasonable ultraspeed etc. of person, every irrational velocity information can consider appearance it is abnormal, it is necessary to
Reject relative trajectory point.
Step 103, according to the positioning time of the tracing point of emphasis commerial vehicle, by positioning time is continuous but geographical position not
The continuous tracing point is rejected.
Emphasis commerial vehicle travels on road, then the tracing point of its positioning also should be continuous acquisition, be not in non-
Linear tracing point.Thus, for discontinuous tracing point, should reject.
It is often necessary to carried out according to the positioning time of tracing point.Positioning time continuous tracing point should be on road
A series of tracing points continuously occurred.It is continuous when positioning time, but during the geographical position discontinuous situation of appearance of tracing point, say
There is exception in bright tracing point, should reject.
As a rule, according to the positioning time of the tracing point, the tracing point is sorted；By geographical position beyond front and rear
The tracing point of scope is rejected between the tracing point of order.
In general, not only need to reject the abnormal tracing point in geographical position, it is also necessary to by tracing point positioning time itself
