Problems solved by technology
At present, when the patrol management system displays the preset patrol route with the route buffer attribute, it needs a huge database management system and spatial geographic data to support it. The system construction and operation and maintenance costs are high and difficult; when there is no spatial map data, The preset route buffer cannot be displayed, which affects the system visualization effect and reduces the efficiency of real-time monitoring

Embodiment Construction
[0038] The present invention will be further described below in conjunction with accompanying drawing.
[0039] The specific implementation of the present invention refers to the coding realization of the two-dimensional display method of the parallel line buffer patrol route on the basis of the software development tool and the commercial map platform. The specific implementation process is as figure 1 Shown, are calculating position points, calculating intersection points, screening buffer range marker points and drawing parallel buffer patrol routes respectively.
[0040] The known content of the preset patrol route attributes in the patrol management system is the patrol passing point, the patrol route line segment, and the route buffer distance:
[0041] n patrol passing points and their latitude and longitude: P 1 ,P 2 ...,P n ;
[0042] n-1 patrol route segments: P 1 P 2 , P 2 P 3 ,...,P n-1 P n ;
[0043] Route buffer distance d.
[0044] Example patrol rout...

The invention discloses a two-dimensional display method for a patrol route in a parallel line buffer area and relates to the field of patrol management systems. The method comprises the following steps: measuring and analyzing a second development interface by utilizing a map platform according to longitude and latitude information of intermediate points of the patrol route and the buffer area distance, and calculating to obtain the line segment direction angle of the patrol route, longitude and latitude information of parallel line positions and longitude and latitude information of adjacent parallel line intersections; discriminating the positions and intersections according to a screening rule of mark points in a buffer area range so as to obtain a mark point combination in the buffer area range of the patrol route; plotting the second development interface by utilizing a graph of the map platform, and drawing the patrol route and the buffer area range. The method is used for two-dimensional display of the patrol route in the parallel line buffer area in the patrol management system.
Description
technical field [0001] The invention relates to a method for displaying a patrol route in a parallel line buffer zone in the field of patrol management systems. Through calculation, the patrol route set by the user with the longitude and latitude of passing points and the distance attribute of the route buffer zone can be composed of straight line segments and arc line segments. Ribbons are displayed on the map platform. When the user performs patrol, the real-time position reported by the patrol personnel is received, and the real-time dynamic monitoring of the patrol duty is realized by comparing with the patrol route. The present invention can be applied to various application scenarios such as border monitoring, police-civilian joint defense, public security patrol, intelligent patrol and so on. Background technique [0002] In the field of patrol management system, it is necessary to realize real-time dynamic monitoring and control of active targets such as patrol pers...
