Abstract
The present invention relates to a kind of Train Control and management system Conformance Testing Environment and utilize this platform to carry out the method for testing of testing protocol consistency. This platform structure comprises backboard, power supply board, cpu bus board, MVB(EMD) board and MVB(ESD) board, on backboard, be provided with core bus. This protocol conformance test method mainly comprises that equipment under test receives the uniformity test of data and the uniformity test of equipment under test transmission data, transmit and receive data by equipment under test, resolve the data format that arrives of sending and receiving, whether information that can intuitive and accurate response data transmission meets protocol requirement.
Description
Technical field
The present invention relates to a kind of assistant analysis test platform, specifically, relates to a kind of Train Control and management system protocol conformanceTest platform, and utilize this platform to carry out the method for testing protocol consistency.
Background technology
Compatible for the train network equipment that different suppliers are produced, all-network equipment need to meet the IEC61375 worldStandard. According to the requirement of TCN uniformity test, before the entrucking of different manufacturers MVB equipment, must carry out function uniformityTest, between test heterogeneous networks equipment communications protocol formulate whether identical, whether can proper communication and equipment between equipmentBetween can correctly resolve receive and send data flow. But the method for protocol test is to produce by model network at presentNormal communication between product, then relies on third party's monitoring equipment and software. In communication process, revise network equipment program, prisonThe data flow of measurement equipment communication whether with the coming to the same thing of amendment, judge with this whether testing equipment meets protocol test requirement.And this kind of means of testing must be complete at master-slave network equipment development, set up after real network connects and just can carry out, and needThe supplier of distinct device cooperatively interacts, and test process is loaded down with trivial details, and test period is long. The present invention develops for this problem exactlyThe TCMS Conformance Testing Environment that is specifically designed to MVB Device-General.
Summary of the invention
The object of the present invention is to provide a kind of in order to verify in vehicle-mounted control network system protocol conformance between each control applianceTrain Control and management system Conformance Testing Environment.
Technical scheme of the present invention is: a kind of Train Control and management system Conformance Testing Environment, this platform structure comprisesBackboard, power supply board, cpu bus board, MVB-EMD board and MVB-ESD board, be provided with backboard total on backboardLine, power panel cartoon is crossed backboard and is connected respectively to cpu bus board, MVB-EMD board and MVB-ESD board, for respectivelyIndividual board provides stable power supply, and described cpu bus board comprises central processing unit, and RS232 protocol controller is describedMVB-EMD board is MVB-EMD device talk card, connects outside tested MVB-EMD equipment, MVB-ESD plateCard is MVB-ESD device talk card, connects outside tested MVB-ESD equipment.
Utilize Train Control and management system Conformance Testing Environment to carry out the method for testing protocol consistency, the methodMainly comprise that equipment under test receives the uniformity test of data and the uniformity test of equipment under test transmission data;
In the time carrying out the data coherence tester of equipment under test reception, from Train Control and management system Conformance Testing EnvironmentCpu bus board send data, data are sent to outside tested through MVB-EMD board or MVB-ESD boardMVB-EMD equipment or MVB-ESD equipment, the interface of equipment under test receives data, resolution data form, and through PCThe data format that end reflection receives, comprises variable name, types of variables, byte offsets, position side-play amount and numerical value, user coupleThe data analysis receiving, judges that the data that equipment under test receives are all to meet code requirement;
In the time carrying out the uniformity test of equipment under test transmission data, outside tested MVB-EMD equipment or MVB-ESD establishesPreparation is sent data, and it is consistent with management system agreement that data are sent to Train Control through MVB-EMD board or MVB-ESD boardThe cpu bus board of property test platform, Train Control and management system Conformance Testing Environment are resolved the data lattice that receiveFormula, and the data format receiving through PC end reflection, comprise variable name, types of variables, byte offsets, position side-play amount andNumerical value, the agreement in data format and specification that user receives platform compares, and judges that the relevant information of exchanges data isThe no requirement that meets specification.
The invention has the beneficial effects as follows:
(1) the present invention can verify in vehicle-mounted control network system, whether the transmission data between each control appliance meet data biographyDefeated specification and the requirement of TCMS protocol conformance, apply this test platform and Data Transport Protocol effectively verified have before entruckingBe beneficial to the debug time that shortens carried network control system and each control appliance.
(2) the present invention carries out deep comparison to data format, mainly comprises variable name, types of variables, byte offsets, biasedThe amount of moving and numerical value, can be intuitive and accurate the information of response data transmission.
