Embodiment Construction

[0023] The present invention will be described in detail below with reference to the drawings and specific embodiments.

[0024] As shown in Figure 1, the regional monitoring processing flow using the dynamic monitoring mechanism of the monitoring center, if only the vehicle entering and leaving the set area is monitored, the specific processing process is as follows:

[0025] 11) The monitoring center sets at least one polygonal area in the electronic geographic map; the setting of the polygonal area can be implemented in the following ways: set multiple location points and the longitude and latitude offset values ​​of each location point, and each location within the offset range The collection of point geographic locations serves as a polygonal area.

[0026] 12) Vehicle-mounted GPS terminal dynamically reports vehicle geographic location information to the monitoring center;

[0027] 13) The monitoring center judges that the vehicle enters and exits the set polygon area based ...

Abstract

The present invention discloses a zoning monitoring method based on a car GPS terminal. A polygonal zone is set on an electronic geographical map preliminarily; when in the running process, a present geographical position of a car is acquired, thus, whether the car enters and exits the polygonal zone can be judged, thereby achieving the zoning monitoring to the car. The present invention also provides two mechanisms that are a monitoring center movement monitoring and a car GPS terminal movement monitoring, thereby conveniently being chosen and used by different operating systems. The present invention further provides a processing method of a zoning speed restriction monitoring, therefore, the zoning monitoring method of the present invention can accomplish the flexible speed restriction monitoring according to different zones.

Description

Technical field [0001] The invention relates to a vehicle monitoring method based on a vehicle-mounted GPS terminal, in particular to a vehicle area monitoring method based on a vehicle-mounted GPS terminal. Background technique [0002] The current vehicle-mounted GPS terminal has gradually begun to be popularized in operating vehicles, and its functions are becoming more and more powerful, including: electronic maps, satellite navigation, voice prompts, scheduling arrangements, anti-theft alarm and other functions. Especially in some special operating vehicles, such as long-distance buses, public transport vehicles, special transportation vehicles, etc., the above functions often still cannot meet their needs. Operational management requires these vehicles to be prohibited from entering certain areas, or in order to further ensure safety, they must strictly comply with the set regional speed limit requirements. The current in-vehicle GPS terminal cannot yet achieve such a funct...
