Embodiment
Train network equipment auto-test-bed of the present invention; As shown in Figure 1; Comprise main frame, man-machine interface, input/output interface, communication interface, power interface, test cable, subtest equipment; Man-machine interface, IO interface, communication interface, power interface all link to each other with main frame; Subtest equipment links to each other with main frame through test cable, and main frame passes through gateway module, the power module of the central control unit of the network control system of Output Interface Control train, long-range input/output module, RS485 commentaries on classics MVB gateway, and the network control system each several part of train is detected.
Described input/output interface comprises analog quantity input/output interface, digital quantity input/output interface.
Described communication interface comprises MVB communication interface, CAN communication interface, serial communication interface.
The test platform that network equipment auto-test-bed (ATE) has been set up a reality is used to detect each networked control system of the train system central control unit (CCU), long-range output module (RIOM), RS485 commentaries on classics MVB gateway and power module.
The method of testing of networked control system of the train system each several part is following:
The method of testing of central control unit (CCU):
As shown in Figure 2, to pass through the on/off that DO controls each CCU in the test process, and carry out the MVB communication test through MVB, test result shows on the display screen of ATE testing table.
CCU downloads test procedure, and ATE programmed control DO lets CCU switch on successively and tests.Test port is the port that ATE issues CCU for fixing MVB COM1, and 0x518 is the port that CCU returns to ATE.If two port proper communications explain that then CCU is in proper working order.
The test of long-range input/output module (RIOM) is divided into RIOM-INDI module testing, RIOM-USDR module testing, RIOM-AI module testing, RIOM system test.
Long-range input/output module RIOM-INDI module test method is:
As shown in Figure 3, all modules all connect together through backboard CAN bus, are connected on the ATE testing table, detect the state of INDI module through the inside CAN bus of RIOM, and test result shows on the testing table display screen.
ATE selects different configurators to carry out the test of module by ATE according to the DI module number through the power supply of DO control DI module simultaneously.Adopt the CAN main wheel to ask DI equipment during test, according to the value of CAN communication and the actual voltage judge module that inserts operate as normal whether.
Long-range input/output module RIOM-USDR module test method is:
As shown in Figure 4, ATE selects different configurators to carry out the test of module by ATE according to the DO module number through the power supply of DI control DO module simultaneously.Behind CAN bus output DO, judge according to diagnostic data in the CAN communication whether DO output is normal simultaneously.Judge in the process of DO output, also need check the closed situation of DO through the resistance of relay closes.
Long-range input/output module RIOM-AI module test method is:
As shown in Figure 5, ATE selects different configurators to carry out the test of module by ATE according to the AI module number through the power supply of DO control AI module simultaneously, and each module is imported AI (5V) in order, and whether through CAN acquisition module AI value, it is normal to carry out judgment device.
Long-range input/output module RIOM whole-machine test method is:
As shown in Figure 6, ATE selects different configurators to carry out the test of module by ATE according to the RIOM module number through the power supply of DO control RIOM module simultaneously.With the communication of CAN communication test core bus, test each module and whether all dispose correctly.
RS485 changes MVB gateway method of testing:
As shown in Figure 7, ATE selects different configurators to carry out the test of module by ATE according to the GW module number through the power supply of DO control GW module simultaneously.Need main card test and RS485/RS232 communication module, through main card communication, test 485 signal intelligences, thereby see whether module converts is correct.Application configuration is fixing MVB COM1 0x510, and what the program of RS485/MVB gateway was fixing is forwarded to port data on the RS485, and communication frequency is 38400.
The power module method of testing:
As shown in Figure 8, ATE selects different configurators to carry out the test of module by ATE according to power module quantity through the power supply of DO control power module simultaneously, the output voltage values of AI acquisition module, and whether carry out judgment device normal.
All power modules all have the DC110V power supply, and the output voltage with AI acquisition module collection power module is presented at magnitude of voltage on the testing table display screen, and provides test result.The power module of RIOM is DC24V, need carry out carrying out the AI collecting test after the dividing potential drop with resistance.
