Abstract

The invention provides a train-ground communication simulating system for train-ground communication testing of a train. The system comprises a data processing module for reading a test script file to obtain ground data; a protocol conversion module which encodes the ground data on the basis of a communication protocol between a simulation target and a train-mounted test target; and a communication module used to send the ground data to the train-mounted test target and receive train data from the train-mounted test target. The protocol conversion module decodes the train data on the basis of the communication protocol between the simulation target and the train-mounted test target. The data processing module records the decoded train data to generate a record file.

Description

technical field [0001] The invention relates to the field of train-to-ground communication, in particular to a train-to-ground communication simulation system and method. Background technique [0002] CTCS-3 train control on-board equipment is an important equipment to ensure the safety of CTCS-3 trains. During the operation of the train, the on-board train control equipment uses the information provided by the ground, such as line information, target distance and route status, and combines the train parameters to automatically generate the allowable speed control mode curve, and compares it with the train running speed in real time. When the train exceeds the speed Take control in time. [0003] In order to exchange information with the ground in real time and ensure the safe operation of the train, the CTCS-3 train control vehicle equipment needs to use the GSM-R communication device to realize continuous and two-way wireless data transmission between the train and the gr...
