Abstract
The invention provides a system determining whether a target gets into or gets out of a designated region on the basis of position data. The system comprises a GPS device which is mounted on the target and used for periodically sending enforcement position data, and a data processing device which is in network connection with the GPS device and is used for acquiring the real-time position data. The present position, the previous position and a previous position state of the target in a coordinate reference system are determined according to the real-time position data, and the previous position state of the target is determined by the position of the previous position relative to a first designated region and a second designated region in the coordinate reference system; whether the target effectively gets into or gets out of the first designated region is determined according to the present position, the previous position and the previous position state. The system is advantaged in that fluctuation in the coordinate reference system caused by self errors of the position data can be avoided, and whether the target actually crosses the designated region can be accurately determined.
Description
Technical field
The present invention relates to location technology, more particularly to a kind of to judge that target passes in and out designated area based on position data
System.
Background technology
Present GPS device on the market, it is possible to achieve positioning, the statistics function such as mileage and speed, therefore it is extensive
It is applied to the fields such as mine, oil or its transport.But, it is well known that even high-precision GPS device, it is sent
Position data and physical location all there is certain deviation, this is that the loss that cannot overcome of current technology is true.
Therefore, if to judge a target that can send position data or with the mesh that can send position data equipment
Whether mark enters or goes out in a designated area, then such case occurs：Target is actual in a close designated area
It is motionless on side or edge, and receive and then can show on the external equipment of its position data that the numeric data of the target exists always
The adjacent edges of the designated area fluctuate back and forth, such as Fig. 1, and the position data of target A is in the reciprocal ripple in a designated area M edge
It is dynamic.It is this to fluctuate to GPS using with great interference, need those skilled in the art to solve the problem.
The content of the invention
The shortcoming of prior art in view of the above, it is an object of the invention to provide one kind is judged based on position data
The system that target passes in and out designated area, for solving to cause target not moving because position data sends equipment itself error
In the case of there is position data and show fluctuation, and then cannot effectively judge the problem of the whether effective designated area of a target,
Solve the technical scheme of above-mentioned technical problem：
According to the first aspect of the invention
It is a kind of that the system that target passes in and out designated area is judged based on position data, including：GPS device, is installed on a mesh
Put on, for the cycle enforcing location data are sent；Data processing equipment, network connection in the GPS device, for obtaining
State real time position data；According to the real time position data determine this position in a coordinate reference system of the target,
Previous position and previous location status, wherein, the previous location status are joined by the previous position relative to the coordinate
Determining, second designated area is along described for the position of one first designated area and the second designated area in test system
The edge of the first designated area to the spacing of external expansion one is obtained；According to described this position, previous position and previous position shape
State determines the target this first designated area described in whether effective entry/exit.
In a preferred version, the data processing equipment positioned at described first in the previous position specifically for specifying
When in region, the previous location status are determined in boundary；When the previous position is located at outside first designated area, really
The fixed previous location status are for out-of-bounds；It is located between first designated area and the second designated area in the previous position
Or when on the edge of first designated area and the second designated area, determine that the previous location status are upper previous
State is constant.
In a preferred version, first designated area and the second designated area are respectively a continuous closed area.
In a preferred version, the real time position data is a GPS location data.
Beneficial effects of the present invention
The previous position of target and previous location status are determined by position data, then in the positional number with reference to this
Judge whether this effectively strides into or step out in the coordinate reference system unavoidably according to the correspondence position in coordinate reference system
One designated area, so as to overcome the position data in the case where target is not moved to show the obstacle that position data fluctuates.
