Problems solved by technology
There is a situation where the balise is lost in this scheme. For example, when the train is running too fast, because the displacement of the train is discrete, there is a situation that the displacements of the two updates of the train do not fall within the trigger window of the balise. The transponder will not trigger and the train loses the location of the transponder at that point

Embodiment Construction
[0036] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary, and are intended to explain the present application, and should not be construed as limiting the present application.
[0037] In order to facilitate the understanding of the present application, before explaining the solution, the existing transponder simulation technology and its shortcomings are generally described. The displacement of the actual train is continuous, but in the balise simulation technology, the displacement of the train is discrete, and the time between two adjacent updates of the displacement of the train is one cycle. The balise simulation can only be updated by improving the displacement of the train. The ...

This application proposes a method and system for balise simulation, wherein the method includes: judging whether the uplink balise and the downlink balise of the train have changed, wherein the uplink balise is the balise closest to the train along the first direction, and the downlink balise is the balise closest to the train along the second direction; when the running direction of the train is the first direction, if the train’s uplink balise and downlink balise change at the same time, the changed downlink balise will be triggered, and the changed downlink balise The balise sends balise information to the train; when the running direction of the train is the second direction, if the train’s uplink balise and downlink balise change at the same time, the changed uplink balise is triggered, and the changed uplink balise sends Transponder information to train. When the train passes a balise, the uplink balise and the downlink balise of the train change, therefore, the present application does not have the situation that the balise is lost.
Description
technical field [0001] The present application relates to the field of simulation technology, in particular to a method and system for transponder simulation. Background technique [0002] The transponder is an important part of the train control system. It is used to provide positioning function for the operation of the train. The accuracy and accuracy of positioning is an important factor affecting the upgrade and automatic operation of the train. Therefore, accurate transponder simulation can improve the accuracy and accuracy of transponder positioning, which can not only facilitate the testing and development of train control systems, improve work efficiency, save costs, but also facilitate train upgrades and automatic operation. [0003] It should be noted that the actual train displacement is continuous, but in the balise simulation, the train displacement is discrete, and the balise simulation can only make the displacement tend to be continuous by increasing the upda...
