Embodiment 1

[0035] figure 1 A flow chart of the expression method of the linear distribution facility provided by Embodiment 1 of the present invention is shown. Such as figure 1 As shown, the expression method of the linear distribution facility specifically includes the following steps S101 to S103.

[0036] Step S101: Receive a user's browsing instruction, and render the layer data of the visible area in the schematic diagram according to the browsing instruction; the browsing instruction includes at least one-dimensional coordinate information of the current browsing position on the schematic diagram.

[0037] The schematic diagram is a customized two-dimensional map, and its customization is reflected in: 1. The lines on the complex two-dimensional map are abstracted into straight lines, which are represented by a one-dimensional coordinate system; Extended browsing.

[0038] Among them, such as figure 2 show, suggest figure 2 It mainly includes the following parts:

[0039] ...

example 25

[0048] Schematic legend, indicating the meaning of each icon in the schematic.

[0049] Rendering includes the process of displaying layer data to the user in a specific way. Schematic scale information, used to assist the user to view the specific position of the schematic information. The schematic diagram can be browsed by dragging left and right with the mouse. When the user drags left and right, a corresponding browsing command will be generated, and the layer data of the visible area in the schematic diagram will be rendered according to the browsing command. The facilities displayed on the linear ground object carrier adopt a layered control method, that is, each type of facility is placed in the same layer, which can easily control the display or non-display of the layer, and which layers are superimposed. .

[0050] A layer refers to a collection of a certain type of graphics or elements, such as a street light layer, a road layer, etc. It not only contains informat...

Embodiment 2

[0061] image 3 It shows a schematic flowchart of the implementation of the method for expressing linear distribution facilities provided by Embodiment 2 of the present invention. Such as image 3 As shown, before step S101 in the first embodiment, the following steps S301 and S302 are also included.

[0062] Step S301: Hierarchically store linearly distributed facility data, including the coordinate system information, facility space information and facility attribute information.

[0063] The linear distribution facility data of all layers are stored and stored according to each layer, and the linear distribution facility data includes coordinate system information, facility space information and facility attribute information.

[0064] You can view the attribute information of the linear distribution facilities, and you can also reserve corresponding interfaces to operate the linear distribution facilities on the schematic diagram to control their working status. For exa...

Abstract

The present invention relates to the technical field of communication, and provides an expression method for linear distribution facilities and a terminal. The method comprises: receiving a browsing instruction of a user, and rendering layer data of a visible region in a schematic diagram according to the browsing instruction, wherein the browsing instruction at least comprises one-dimensional coordinate information of a current browsing position on the schematic diagram; according to the one-dimensional coordinate information of the current browsing position on the schematic diagram and pre-stored control point information, calculating a geographical coordinate of the current browsing position, wherein the control point information is a set of points comprising one-dimensional coordinatesand geographical coordinates corresponding to the one-dimensional coordinates; and according to the geographical coordinate of the current browsing position, calling an electronic map and displayingthe layer data of the schematic diagram on a corresponding position of the electronic map. According to the expression method and the terminal provided by the present invention, the electronic map canbe easily and interactively linked with the linear distribution facilities through the interconversion between the one-dimensional coordinate of the schematic diagram and the geographical coordinateto achieve deeper integration.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a method for expressing a linear distribution facility and a terminal. Background technique [0002] For public facilities such as tunnels, subways, bridges, rail transit, underground pipe corridors, etc., in order to ensure their normal operation and monitor their status, it is necessary to deploy a large number of auxiliary, sign, monitoring, fire protection, emergency, lighting and other facilities. If we want to manage the location, status, and attributes of these facilities, we need a graphical means to express the spatial distribution, actual location, and mutual relationship of these facilities to assist us in our work. Currently, the most commonly used management methods are: [0003] First, use two-dimensional maps for direct management, that is, linear features and related facilities are treated as different layers and directly superimposed on the two...
