Multiplexing uses interface case, the function case achievement for the demonstration project that interconnects, and major revision meets the operation field locally required
The data of scape case, operating index case and local engineering circuit data verification.
Test execution is broadly divided into three phases: producer's self-test stage, cross-beta platform test stage, on-the-spot test
Stage.
First stage, producer's self-test stage
Producer's self-test requires producer to complete corresponding work in oneself platform, need producer carry out itself product test,
The engineer application line system that interconnects test and engineering circuit data test, require software zero defect or meet soft after test
Part, data outlet requirement, to ensure compliance with the standard design function that interconnects.
Second stage, cross-beta platform test stage
After completing producer's self-test, meets test access condition and arrived according to version management publication software with data
Cross-beta platform carries out the test job of cross-beta platform.
In the cross-beta platform test stage, each producer's onboard system is mainly verified in the conllinear fortune of other family's ground systems
Battalion and cross-line operation.Test job is divided into the Engineering Interface test phase that interconnects, the engineering that interconnects function exact p-value
It stage and interconnects these stages in project data exact p-value stage.To ensure going on smoothly for cross-beta, interconnection is mutual
Tong Ge signal manufacturer should provide at least two concentration zones as sample segments and carry out initial stage test, and the later period gradually mends according to project process
Remaining neat concentration zones.
Engineering Interface test phase
Each onboard system and each ground system is needed to carry out one-to-one interface testing, this family is vehicle-mounted and ground
Interface testing not within the scope of cross-beta.Also needing to carry out interface to two ground systems for having interface between ground
Interface testing.Interface testing follows a design documentation, verify both sides send message information it is whether consistent with Interface design, packet
Include, when train enters the station, when train is turned back, interface message consistency of the train when ground administrative area switches etc. under various states.
Test, the relevant issues occurred in test process, still by each after modification wherein are responsible for by respective producer for secure communication protocols
This is responsible for from producer.It can ensure that any producer is vehicle-mounted after the completion of test and carry out normal information friendship in any producer's ground system
Mutually.
The function exact p-value stage
Each onboard system is needed, according to the test outline case content worked out, to carry out with each ground system
Function confirmation one by one.Function exact p-value can choose anywhere and scene carries out, and confirm the state of function interaction both sides
Correctness, the vehicle-mounted function exact p-value with ground of this family is not within the scope of cross-beta.It can ensure to appoint after the completion of test
Anticipating, producer is vehicle-mounted to carry out normal function realization in any producer's ground system.
The project data exact p-value stage
The function that same scene is confirmed one by one is needed according to test outline identification, is carried out one by one in scene location true
Recognize, forms the verifying to engineering construction data correctness.Data validation test carries out all places for meeting function realization
Confirmation, the vehicle-mounted project data with ground of this family are tested not within the scope of cross-beta.It can ensure any factory after the completion of test
Family is vehicle-mounted to carry out normal function realization under the various place scenes of any producer's ground system.
The present embodiment by the building of the cross-beta platform of the CBTC system that interconnects, indoor cross-beta and management with
And on-the-spot test is debugged and management, can effectively organize the verifying interconnected, and ensures interconnection technology engineer application
Smoothly implement.
