Abstract

The invention provides a method for improving the sending accuracy of a transponder message of a simulation system. The simulation system comprises a dynamics model, a wayside equipment model and an interface unit. The method comprises the following steps: the dynamics model obtains a plurality of train operation parameters and sends the parameters to the interface unit; the simulation system comprises a dynamic model, a wayside equipment model and an interface unit. The interface unit updates the antenna position according to the train operation parameters, and obtains transponder informationwithin a preset distance of the updated antenna position from the wayside model device to generate a transponder list to be searched, and searches the transponder list to be searched. The interface unit updates the antenna position according to the train operation parameters, and obtains transponder information within a preset distance of the updated antenna position from the wayside model deviceto generate a transponder list to be searched.

Description

technical field [0001] The invention relates to the field of train automatic control, in particular to a device and method for improving the message sending accuracy of a transponder in a simulation system. Background technique [0002] The rail transit signal system needs to be tested before the actual operation to ensure the stability and safety during the actual operation. [0003] In the test phase, the transmission of the transponder message is tested through the simulation system. A train simulation platform usually includes dynamic models, trackside equipment models and interface units. In the prior art, the dynamic model sends train operating parameters at a preset time period, and the trackside equipment model sends transponder information at a preset time period. The preset time period controlled by an ordinary timer can still meet the requirements in the CBTC test (generally 120km / h and below), but in the high-speed rail test (the maximum speed reaches 400km / h),...
