Embodiment Construction
[0033] The present invention will be further described below in conjunction with specific examples.
[0034] Use logical line segments to describe the routes operated by transportation equipment:
[0035] Such as figure 1 The shown route is composed of logical line segments, and the division of logical line segments is based on the application requirements of specific route maps. A logical line segment is uniquely determined by the coordinates of its two endpoints, and one of the endpoints of a logical line segment is usually determined by the endpoint coordinates of another known line segment connected to it (when there is no known connected logic due to reasons such as the first or end logical line segment When a line segment is used, the coordinates of one end point are specified in advance), and the coordinates of the other end point of the logical line segment are determined by the known end point coordinates and the length of the logical line segment. The length of the...

The invention relates to a method for displaying a transport facility and a running position thereof. The method comprises the following steps: drawing a running line of the transport facility by a logic line segment; drawing positions of other facilities on the way of the transport facility by taking the logic line segment representing the line as a reference object; determining the shape of a current main body and positions of components of the transport facility by taking the logic line segment of the current covered line of the transport facility as a reference object; and periodically orwhen a position notification event is received, refreshing and displaying a main body, the components and attached character information of the transport facility. Compared with the prior art, the method has the advantages that the method can dynamically display the attached information of the facility, is favorable for accurately comparing the positions of the transport facility and other facilities on the way of the transport facility, has the practical value of improving the efficiency and the effect of comparison and observation, and has wide application prospect in the systems of control, monitoring, simulation, maintenance and the like which are related with the transport facility.
Description
technical field [0001] The present invention relates to the design and application of accurate real-time dynamic display of the positions of transportation equipment (such as trains and automobiles) and their parts in various computer graphics operation display interfaces, and in particular to a method for displaying transportation equipment and their operating positions. Background technique [0002] In the graphical display interfaces of numerous control, monitoring, simulation, and maintenance systems (such as computer interlocking systems, train dispatching systems, microcomputer monitoring systems, diagnostic maintenance systems, and simulation test platforms), it is often necessary to display the transportation equipment on the line in real time (e.g. a train) and its location. [0003] At present, there are three ways to realize the display of transportation equipment and its location: [0004] (1) The position is represented by the occupation and clearing of the tra...
