Problems solved by technology

[0005] The train control protocol test platform in the prior art lacks an independent test method and test environment for the train-ground communication protocol, and often needs to be tested under actual equipment, which will lead to incomplete testing, high test complexity, and long time. problem; in addition, the testing of the existing platform often only observes the services that the high-level can receive, but cannot monitor the information exchange at the bottom, so that it is impossible to observe the response of the system under test to the abnormal behavior of the bottom

Embodiment Construction

[0043] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0044] Such as figure 1 As shown, it is a schematic structural diagram of the test platform of the train-ground transmission protocol of the train operation control system of the embodiment of the present invention. This embodiment includes: a test system part 1 and a protocol stack simulation part 2.

[0045] Among them, the test system part 1 is used to integrate the test cases of the SFM protocol block according to the vehicle-ground transmission protocol, that is, the business function of the EuroRadio protocol, schedule and manage the corresponding vehicle-ground communication business processes, and is also used to perform management interface conversion and adaptati...

Abstract

The invention discloses a testing platform for a train-ground transmission protocol in a train operation control system and a construction method thereof, and the testing platform comprises a testing system part for integrating testing cases of a space frequency modulation (SFM) protocol block according to service functions of a train-ground transmission EuroRadio protocol and scheduling corresponding train-ground communication processes, and a protocol stack simulation part for collecting protocol layers under the EuroRadio protocol into a general protocol layer and simulating the service functions of the CFM protocol block in a GSM-R network. The testing platform can not only observe the services received by a high layer but also monitor the information exchange of a bottom layer and observe the response of a system to be tested to abnormal behaviors of the bottom layer, thus finishing the conformance testing to the train-ground security transmission protocol in the train operation control system.

Description

technical field [0001] The invention relates to the field of train communication protocol testing, in particular to a test platform for a train-ground transmission protocol of a CTCS3-level train operation control system and a construction method thereof. Background technique [0002] At present, my country's high-speed railways are developing rapidly, among which the CTCS-3 Chinese Train Control System (Chinese Train Control System) has passed the Global System for Mobile Communications for Railways (GSM-R) specially designed for railway communications. , to realize continuous and two-way information transmission between the ground and the train, and it is a train operation control system based on wireless communication. [0003] The train and the ground transmit control information related to train operation safety through the air interface, and it is necessary to ensure that the control information is transmitted safely, reliably and in real time. Therefore, in the CTCS-3...
