Embodiment Construction

[0059] The present invention will be further described below with reference to the drawings and embodiments.

[0060] As shown in the figure above, it is the detailed process of the user returning the car.

[0061] The core problem of this product is whether the calculated position of the motorcycle in the dotted box matches the position of the electronic fence, that is, calculate the range of the designated parking area for the motorcycle, which involves the selection and optimization of multiple algorithms.

[0062] Method analysis

[0063] The core problem of this product is whether the motorcycle successfully stops in the specified area, such as convex polygon and concave polygon area.

[0064] Method selection

[0065] From the point of view of mathematics, it is whether a point is in the specified area. Common point and polygon algorithms are dot line judgment method, included angle sum method, and ray method. The ray method uses concave polygon, dot line judgment method and clamp ...

Abstract

The invention discloses an electronic fence, which comprises a dot line judgment method. According to the dot line judgment method, firstly, each edge of a polygon is taken as a directed line segmentwhich is connected in an end-to-end mode. If the direction of a certain point relative to each edge of the polygon is the same, the certain point is located in the polygon. The core step of the electronic fence is to figure out the values of two points (x1, y1) and (x2, y2) closest to a point (x, y), and is applied to a convex polygon. According to the electronic fence provided by the invention, the optimized algorithm of the electronic fence is achieved, so that the efficiency in searching motorcycles which drive in and out of the e electronic fence is improved. The software structure and thedatabase structure of the electronic fence are designed to realize the electronic fence. According to the design of the electronic fence, the polygon is directly drawn on a map, which has a great error with an actual geographical longitude and an actual geographical latitude. During the drawing of the electronic fence, the longitudes and the latitudes of a plurality of corners are determined as much as possible. After that, adjacent corners are connected. Meanwhile, the map is ensured at a maximum multiple, and the error can be guaranteed to be the minimum.

Description

Technical field [0001] The invention belongs to the field of electric power maintenance, in particular to an electronic fence. Background technique [0002] With the vigorous development of the power system, the number and deployment scope of various public power facilities have increased, but the corresponding power failures are also on the rise. In the traditional power failure maintenance process, construction personnel need to signal The indicator lights or indicating racks are placed on the construction site in time, and even some construction sites need to set up fences to strengthen alertness. However, due to the electric power repair and daily construction process, it is often easy to display the indicator light or the indicator rack placement position is not eye-catching, causing non-construction personnel to enter by mistake, thus affecting the construction process, there are also potential safety hazards. In order to overcome the shortcomings of the prior art, the pre...
