Description
Technical field
The present invention relates in the various computer graphicals operation display interfaces to relate in particular to a kind of method that shows facilities for transport and communication and run location thereof about the design and the application of accurate Real time dynamic display facilities for transport and communication (for example train, automobile) and position component thereof.
Background technology
In the graphic display interface of numerous control, monitoring, emulation, maintenance system (for example computer interlock system, train dispatching system, microcomputer detecting system, diagnosis maintenance system, simulation test platform), often need facilities for transport and communication (for example train) and position thereof on the real-time circuit.
At present, facilities for transport and communication and position thereof show three kinds of implementations:
(1) taking and go out to represent clearly the position with track
Circuit is basic section unit with track section (rail or track circuit), the track section that facilities for transport and communication cover (perhaps between first group of wheel and last group wheel) is shown as " taking " state, other track section is shown as " going out clearly " state, like this by observing the state of track section, the position at facilities for transport and communication place as can be known then.This method is that unit shows the facilities for transport and communication position with the track section, and precision is very low; When a plurality of facilities for transport and communication, do not know the position of the facilities for transport and communication of concrete running number in addition.
(2) show successively on each logic block with running number and represent the position
Circuit can be littler than track section the logic unit segmentation, when facilities for transport and communication are positioned at certain logic section, just in this segmentation, show the running number of facilities for transport and communication.Like this, on each logic section, show successively, represent moving of facilities for transport and communication with running number.This method more goes a step further than (1) kind method on precision, but has ignored the position display of facilities for transport and communication when a segmentation carries out the transition to another segmentation.
(3) represent the position with moving of picture
Move continuously on the line with picture (can attach text messages such as running number) and to show facilities for transport and communication and position thereof.This method can show the facilities for transport and communication position with various precision in the linearity region, has solved the jumping characteristic problem of preceding two kinds of methods.But work as facilities for transport and communication at the transition zone that turns another circuit from a circuit, picture can not be transferred with circuit, often such transition zone have to be neglected in line map.
Above method all fails thoroughly to resolve " all sections all show facilities for transport and communication accurately position " on the line problem.And high precision shows that the position of facilities for transport and communication (and each parts) is extremely important concerning simulation test platform.For example, in the simulation test platform of City Rail Transit System, need contrast train head position and platform anchor point position; Need accurately to contrast the position of train antenna and the position of the other beacon of rail; The position that needs physics such as the position of accurate contrast train front and rear wheel and track circuit and/or logic train spacing point.
