Specific embodiment
The present invention will be further described with reference to the accompanying drawings.
CBTC system automation test structure includes three modules: testing engine, tested CBTC software signal system and
The trackside emulator of external condition emulation is provided, as shown in Figure 2.Wherein, testing engine, which is contained, interacts acquisition with emulation module
Or the interface of order trackside unit status.The key subsystem of tested CBTC software signal system includes mobile control unit
(MCU), trackside equipment control unit (ECU) and control unit for vehicle (VCU), wherein containing the complete soft of three control units
Part.Trackside emulator, which contains, receives trackside control unit to the control command of trackside component, and to trackside component control unit
Send the emulation trackside component (Simulate ways ide element) of trackside unit status.
Referring to Fig. 1, CBTC system automation the test of the invention emulation mode of trackside emulator, including following step
It is rapid:
Step S1 reads each trackside equipment data in data form by the Python script write.In data form,
Divide the information of form definition trackside equipment according to distinct device type and service logic.It on the one hand include road by taking track switch as an example
The definition of trouble position, i.e., the corresponding relationship for determining antiposition Yu left and right position of each track switch, for end item, there is also include left
The three-throw turnout of right three kinds of positions.It on the other hand include the definition of track switch and other equipment such as track section incidence relation, track switch
There are interaction relation between track switch, when receiving the order for coming Selftest Engine or some mobile track switch of trackside equipment control unit
When, emulator needs to pull two track switches with interaction relation to designated position simultaneously, guarantees the two simultaneously in positioning
Or it is in antiposition simultaneously, to meet signals security rule；Meanwhile track switch and track section have an incidence relation, i.e., each
Track section where track switch is its switch section, carrys out Selftest Engine or trackside equipment control unit occupies some when receiving
When the order of track switch, emulator needs to occupy corresponding switch section and locking track switch is to forbid pulling.Therefore, trackside is being read
When device data, need to read and store simultaneously various trackside equipments itself definition data and its mutual incidence relation
Data.
Accordingly, the structure of the trackside equipment data finally read is as shown in Figure 3.Fig. 3 is with track switch and two kinds of track section
It is illustrated for equipment, due to the intrinsic coupling of rail traffic signal system, the especially complexity of interlocking of signals rule,
In the trackside equipment data structure actually generated, the trackside equipment quantity of each type is even up to a hundred from several to dozens of
Conjunction differs, and one-to-one, one-to-many and multi-to-multi association is widely present between same kind or different types of trackside equipment
Relationship, it may be said that trackside data structure has biggish complexity.
Step S2 reads each trackside equipment IO in data form by the Python script write, and establishes I/O fabric.
Trackside equipment is defined in data form corresponds to electrical subrack (Rack), board port belonging to the title and its point of I/O object
(Port), the information such as opposite point (Bit) in board.In true CBTC signal system, trackside equipment control unit is root
Specific trackside equipment control command is sent to trackside according to above- mentioned information, or receives the trackside equipment state letter from trackside
Breath.Therefore, trackside emulator, which must obtain these information, could accurately send and receive information, with trackside equipment control unit and
Testing engine interacts.I/O fabric are as follows: the three-decker of " with respect to point in electrical subrack-board port-board ", such as Fig. 4
It is shown.
Data check is carried out while reading each trackside equipment data and trackside equipment IO by the Python script write.
Promote the data reliability of CBTC signal system and automatic test.
Different type trackside equipment has different I/O traffic logics, IO configuration and type of action, can substantially be divided into letter
Single and complicated two kinds of situations, as shown in Figure 5.By taking semaphore as an example, service logic mainly includes the opening of various signals, according to
Concrete configuration different service types (such as interlocking signalling, Wayside signal, shunting signal) have several different clearing signals；
Correspondingly, it also includes several relays that emulator, which needs input point object to be simulated, output point object includes two filaments
Relay；After receiving the input order from trackside equipment control unit and inputting point information, emulator needed in 2 seconds
Movement, overtime then cause signal trouble, default simulated actions delay is 1 second.As shown in Figure 6.In Fig. 6, input is input,
Output is output, and DJ is relay.
It should be noted that the movement of trackside emulator should consider two aspects: the first, regular event is accurate fast in guarantee
While fast, the scene for simulating true trackside equipment movement, such as the movement of semaphore output relay should be also considered as far as possible
Default delay is set as 1 second, is the reproduction to actual signal machine trackside actuating of relay delay, guarantees the true of emulation with this
Property.The second, action failure is the case where true trackside equipment is likely to occur, and emulator must support fault simulation, this is also to survey
The big event of examination, such as when semaphore order red signal, emulator simulation output relay status remain DJ fall and
2DJ is picked up, and is a kind of fault scenes.
Step S3 establishes " device type-data according to distinct device types of tissue trackside equipment data and its I/O fabric
Structure-I/O fabric " mapping relations.The mapping relations are reading and the real-time channel that trackside equipment state is arranged, this channel
Two kinds are broadly divided into, i.e. testing engine correlation is related to trackside equipment control unit.It is briefly described by taking track switch as an example.Such as Fig. 7
It is shown: when trackside emulator receives testing engine or after pulling track switch order of trackside equipment control unit, if checked
Track switch current location is not inconsistent with command position, then needs to pull track switch, it is necessary first to which that checks track switch determines antiposition configuration, clearly to answer
Track switch is pulled positioning or antiposition by this, and the lookup of the configuration information is based on " device type-data structure " mapping relations；
Then need to check that point configures, with the point that should be clearly arranged, the lookup of the configuration information is based on " data structure-IO
Structure " mapping relations；Finally, judging again after site setting success and reporting track switch current location, process terminates.As it can be seen that " setting
Standby type-data structure-I/O fabric " mapping relations are reading and the real-time channel that trackside equipment state is arranged.
Step S4, according to " device type-data structure-I/O fabric " mapping relations, trackside emulator and trackside control are single
Real time communication, trackside emulator read and are arranged trackside equipment state between member or between trackside emulator and testing engine.
Above embodiments are used for illustrative purposes only, rather than limitation of the present invention, the technology people in relation to technical field
Member, without departing from the spirit and scope of the present invention, can also make various transformation or modification, therefore all equivalent
Technical solution also should belong to scope of the invention, should be limited by each claim.
