Abstract

The invention provides a station yard information graph drawing method and system based on canvas. The method comprises the steps that an acquisition server acquires station yard equipment position information of station yard equipment in a station yard equipment diagram according to station yard equipment information, and allocates station yard equipment coding information to the station yard equipment; the acquisition server sends station yard equipment information to the maintenance network server, and acquires state information of corresponding station yard equipment from the maintenance network server; the acquisition server sends the state information of the station equipment, the position information of the station equipment and the coding information of the station equipment to terminal equipment connected with the acquisition server; and the terminal equipment draws a station yard graph through the canvas. In this way, the canvas technology can be applied to drawing of the station yard graph of the rail transit system, the drawing and updating process of the station yard graph is simplified, software upgrading and maintenance are facilitated, maintenance personnel can knowthe state of the whole station yard equipment through a browser of the terminal, and debugging and maintenance are facilitated.

Description

technical field [0001] Embodiments of the present invention generally relate to the field of station map drawing, and more specifically, relate to a method and system for drawing station information graphics based on canvas. Background technique [0002] In the rail transit system, it is necessary to graph the station information and draw an intuitive 2D station map. The drawing of the existing 2D station map is developed based on the C / S structure, such as Flash, SVG (Scalable Vector Graphics, scalable vector markup map), div+vss, and some of them also pass the VML (Vector Markup Language , vector can be labeled map) for plotting. These drawing methods are generally complicated and cumbersome in the drawing process, and it is not convenient for station equipment information update and software upgrade. Contents of the invention [0003] According to an embodiment of the present invention, a canvas-based scheme for drawing station information graphics is provided. [00...
