When a new aerodynamic brake unit changed by train, or trouble-shooting reason on certain aerodynamic brake unit
When it is not necessary to being tested to whole locomotive and being only needed to this element is tested, locomotive do not need enter live line work shape
State.First the compressed gas source in workshop is linked into gas-pressure adjustable feed unit 2, and makes it reach brake test object supply
Required atmospheric pressure value, then data sampling sensor 13 is connected on correction module and carries out synchronous correction, once correction terminates, I
Data sampling sensor 13 is connected on Devices to test, further according to brake supplier provide braking parameters proceed by correlation
Test, such as sealing, brake required time etc..If result meets the parameter of supplier's offer, then equipment can
Run, otherwise just can find the part of damage.So trouble unit can be found in maintenance, stop without integral replacing
Car control unit, saves cost.
In a kind of specific embodiment of the test system providing for the present invention please further refer to Fig. 6, Fig. 6 at locomotive
Integration testing philosophy schematic diagram in electriferous state.
When performing a test, first by unit of testing and controlling, data acquisition unit 1, gas-pressure adjustable feed unit 2, data
Collection expanding element 5 be together in series by CANOpen bus it is however generally that, data acquisition expanding element 5 correspondence one
Aerodynamic brake unit.Then again the input air pressure of the input air pressure of data acquisition unit 1 and all expanding elements is connected to and stops
Car atmospherically, all data sampling sensors 13 is connected on correction module, sends instruction by control unit, can manually or from
Dynamic, all of data sampling sensor 13 is disposably verified and finishes.After verification terminates, need to connect data sampling sensor 13
Enter and start to test to wait unit of testing and controlling to send instruction to all of aerodynamic brake unit.Because there being data acquisition expansion single
Unit, the instruction that we send on intelligent terminal 32 can be acted as to all of aerodynamic brake unit by the first valve island module
With such as test assistant cylinder, it would be desirable to its aerofluxus, internal air pressure being reduced to zero, then again inflates, keeps one section
Its air pressure numerical value is seen whether in range of error, thus proving its sealing after time.Originally one test completes afterwards again
Repeat these steps to second to test.Now these actions can disposably complete, and each corresponding data can be by
CANOpen bus transfers back to unit of testing and controlling.After being completed, test report will be automatically by wired or wireless
Network is saved on the server that client specifies.Originally test an aerodynamic brake unit time be about 2 hours 30 points, test
Whole locomotive may need 2 to 3 days, because it has more than ten or even twenty or thirty aerodynamic brake unit, just can solve half a day now
Certainly all of test, not only saves manpower and materials, more accelerates the turnover of train.Ensure that reviewing of test report simultaneously
Property and reliability, it is to avoid the probability of artificial modification.
Specific case used herein is set forth to the principle of the present invention and embodiment, the saying of above example
Bright it is only intended to help and understands the method for the present invention and its core concept.It should be pointed out that the ordinary skill for the art
For personnel, under the premise without departing from the principles of the invention, the present invention can also be carried out with some improvement and modify, these improvement
Also fall in the protection domain of the claims in the present invention with modifying.
