[0023] The technical scheme and technical effects of the present invention will be further described below through specific examples. The following examples are explanations of the present invention and the present invention is not limited to the following examples.

[0024] like Figure 1 As shown, the automated test platform includes a power supply unit, an industrial computer, a whole machine signal unit and a single board test unit, and the plug boxes are connected by cables. Specifically, the power supply unit is connected to the industrial computer, the whole machine signal unit and the single board test unit respectively, the whole machine signal unit is connected to the DMI display and the rail vehicle operation control device host 21 respectively, the single board test unit is connected to the rail vehicle operation control device single board, and the industrial computer is connected to the human-computer interaction module and the whole machine signal unit respectively.

[0025] Furthermore, the power supply unit includes a voltage-stabilized power supply module 16, an adjustable power supply module 15 and a program-controlled power supply module 14. The voltage-stabilized power supply module is connected to the single-board test unit and the whole machine test unit respectively. The adjustable power supply module is connected to the whole machine signal unit and the program-controlled power supply module respectively. The program-controlled power supply module is connected to the single-board test unit and the industrial computer respectively. The power supply unit uses the program-controlled power supply module and the adjustable power supply module to realize program-controlled input or output.

[0026] Among them, the industrial computer unit has multiple peripheral interfaces, including HDMI interface, multiple Ethernet interfaces, USB interface, serial port, audio interface, etc., which are connected to the whole machine signal unit for the control of the entire automated test platform.

[0027] During operation, the industrial computer controls the output voltage of the programmable power module inside the power supply unit through the communication interface. The entire power supply unit outputs two 24V and two 48V. One 24V and one 48V are used to power the signal unit of the whole machine, and the other 24V and another 48V are used to power the single-board test unit.

[0028] Furthermore, the whole machine signal unit includes a host signal module 11, a power switching module 12, a power module 13 and an audio test module 10. The power module is respectively connected to the power switching module, the adjustable power module, the industrial computer and the audio test module. The power switching module is connected to the host signal module. The host signal module is respectively connected to the industrial computer and the host of the rail vehicle operation control device. The audio test module is respectively connected to the industrial computer and the host of the rail vehicle operation control device. The whole machine signal unit is mainly responsible for the whole machine function test of the rail vehicle operation control device. The power switching module switches the working power provided by the power unit obtained by the power module to provide power to the host signal module, and the power module directly provides working power to the audio test module.

[0029] Specifically, the host signal module is connected to the industrial computer through a LAN interface, the power module is connected to the industrial computer through an RS485 / RS232 interface, and the audio test module is connected to the industrial computer through a USB interface.

[0030] When working, the industrial computer controls the power switching module to realize program-controlled power output and supply power to the whole rail vehicle operation control equipment. It can also be used for power reverse connection test: through the Ethernet communication interface, the host signal module and the audio test module are controlled to simulate the output of the working level, tube pressure, speed, locomotive signal, audio and other signals. These signals are calibrated to meet the signal output requirements, and can simulate GMS, BTM, axle report and rail vehicle operation control equipment communication. By inputting the simulated signal into the rail vehicle operation control equipment host, the comprehensive test system obtains the rail vehicle operation control equipment host status and DMI information through CAN communication, compares the difference with the simulated signal input, and judges that the rail vehicle operation control equipment host test has passed if it meets the set inspection standards.

[0031] The single-board test unit includes a single-board test plug-in box 18 and a single-board test rack 17. The single-board test rack is connected to the single-board 19 of the rail vehicle operation control equipment, and mainly provides access to all single boards of the rail vehicle operation control equipment. Each functional board has an independent slot and provides an insertion identification signal. The single-board test box is mainly responsible for the single-board test of the rail vehicle operation control equipment. Each single board under test has a test board connected to it, which provides the necessary control signals for the board test and displays the test status through the front panel indicator light. It is responsible for executing the control of the single-board test logic and transmitting the test results back to the industrial computer.

[0032] In summary, the rail vehicle operation control equipment automated comprehensive test system mainly includes rail vehicle operation control equipment whole machine test and rail vehicle operation control equipment single board test. The comprehensive test system can simultaneously support distributed and centralized host tests and host A / B system separate tests. The comprehensive test system automatically performs test verification based on scripts.

[0033] Specifically: When the automated test is executed, the script is executed through the converted automation, and the execution results obtained by the comprehensive test system and the feedback information of GYK (railway vehicle operation control equipment) are all fed back by automation. All tests adopt a closed-loop test method. For example, when testing the whole machine, the test case simulates the working level, pipe pressure, speed, locomotive signal, audio and other signals to send to the rail vehicle operation control equipment host, and collects the working state, pressure value, mileage value, speed value and light type of the rail vehicle operation control equipment host, compares the difference between the input and collected signals, calculates the signal accuracy, and determines whether it meets the set inspection standards. If it does not pass, it prompts unqualified items, checks the problems and repeats the test until it meets the inspection standards. When testing the single board, simulate the voltage, current, pulse, level, communication and other signals to the rail vehicle operation control equipment single board, and collect the output signal of the rail vehicle operation control equipment single board, compare it with the input signal, and determine whether the voltage, current, solenoid valve, locomotive signal, communication, audio and other indicators meet the technical requirements. If it does not pass, it prompts unqualified items, checks the problems and repeats the test until it meets the inspection standards.

[0034] Furthermore, the power supply part test includes power supply range, power, overvoltage, undervoltage, reverse connection protection, etc.; audio index test includes signal level, signal-to-noise ratio, power, distortion, frequency response test, etc.; locomotive signal related test meets all standards involved in TB / T 3287, TB / T 3060, and JT-C, low-frequency sensitivity, return coefficient, strain time, and standard conversion time test. Any combination of test selection; performance test includes distance measurement, speed measurement, and pipe pressure (each channel is tested independently); software function test includes BTM communication, GMS communication, extended communication, self-test function, etc., supports script-based automatic test verification, and can select batch script test verification. At the same time, it supports interfaces for importing test cases and online editing of test cases and test scripts according to different test scenarios. The source signals of all detection information have debugging ports for easy debugging and calibration.

[0035] The process of testing the rail vehicle operation control equipment using the rail vehicle operation control equipment automated comprehensive test system is as follows: Before the test begins, the comprehensive test system will perform a wiring self-check. If the communication is abnormal, the wiring problem needs to be checked until the self-check passes. For new test items, you can choose to perform a whole-machine test or a single-board test on the rail vehicle operation control equipment. When choosing to perform a whole-machine test on the rail vehicle operation control equipment, fill in the configuration information and start the test. Choose to test a single system or a dual system. The single system is the basic configuration of the rail vehicle operation control equipment type operation monitoring device, which includes a set of hardware equipment, while the dual system uses two sets of hardware equipment. The comprehensive test system compares the collected rail vehicle operation control equipment signal with the analog input signal and determines whether it passes the test according to the inspection standard. The test ends after the single system test passes. If the test fails, you can choose whether to retest. In the dual system test, after testing one system, the comprehensive test system prompts to cut the system. After both systems are tested, the test ends. When the whole machine test fails, select the unqualified item. The comprehensive test system will give the corresponding faulty board information. The corresponding board can be tested again on a single board. The specific unqualified items can be obtained through the test. After troubleshooting, the whole machine test can be re-performed. When testing a single board, insert the test board into the single board test unit, and start the test after automatically entering information through the scanner. The test ends when the test is qualified. If the test fails, you can choose whether to retest. When the single board test fails, select the unqualified item, and the comprehensive test system will pop up the fault diagnosis interface, including the troubleshooting suggestions for the unqualified item, the fault-related hardware schematic diagram and the physical diagram. After the test ends, you can save the test results, query and print the report.

[0036] The automated comprehensive test system for rail vehicle operation control equipment can significantly improve test efficiency, reduce manual intervention, lower test costs, and ensure the quality and reliability of rail vehicle operation control equipment, which is of great value to the equipment quality management and maintenance work of the electrical management unit.

[0037] Embodiment 2: This embodiment provides an automated comprehensive testing system for rail vehicle operation control equipment, which further optimizes the automated comprehensive testing system for rail vehicle operation control equipment provided in the first embodiment.

[0038] In this embodiment, the rail vehicle operation control device adopts GYK-160 to implement the testing of the whole machine and single board of the GYK-160 device, improve the testing efficiency of the GYK-160 device, reduce the testing cost, and enhance the accuracy and reliability of the test.

[0039] An automated comprehensive test system for rail vehicle operation control equipment comprises: a power supply unit, an industrial computer, a whole machine signal unit, a single board test unit, a signal adaptation unit 5, a fan unit 6, a human-computer interaction module and a PDU power supply 8, wherein the PDU power supply is respectively connected to the industrial computer, the power supply unit, the fan unit and the human-computer interaction module to provide working power for the comprehensive test system; the power supply unit is respectively connected to the industrial computer, the whole machine signal unit and the single board test unit, the industrial computer is respectively connected to the human-computer interaction module and the whole machine signal unit, the whole machine signal unit is connected to the signal adaptation unit, the signal adaptation unit is connected to a DMI display 20 and a host of rail vehicle operation control equipment, and the single board test unit is connected to a single board of the rail vehicle operation control equipment.

[0040] The whole machine signal unit is mainly responsible for the whole machine function test of the rail vehicle operation control equipment, including the host signal module and the power module, etc. The industrial computer controls the host signal module through the communication interface to simulate the working conditions, pipe pressure, speed, locomotive signal, light display, audio and other signals, retrieve the braking status, and provide fault injection tests such as pipe pressure, speed, and valve.

[0041] When testing the whole machine of the rail vehicle operation control equipment, it can simulate the generation of conditional signals such as locomotive signals, working condition signals, speed signals, pipe pressure signals, etc. required by the rail vehicle operation control equipment, and can collect emergency braking, normal braking, flameout signals, pressure holding signals, and communication signals output by the rail vehicle operation control equipment to determine the working conditions of the corresponding channels of the rail vehicle operation control equipment. The single-board test of the rail vehicle operation control equipment can simulate the generation of conditional signals such as voltage signals, current signals, pulse signals, level signals, communication signals, etc. required by the single board, and can collect the signals output by the unit to determine the working conditions of the single board of the rail vehicle operation control equipment.

[0042] The whole machine signal unit and the single board test unit can realize the whole machine and single board test of the rail vehicle operation control equipment. The power supply unit provides working power for the whole machine signal unit and the single board test unit. The human-computer interaction module can select the test type and display the test progress and test results in real time. The fan unit is used for heat dissipation. The industrial computer is connected to the whole machine signal unit for the control of the entire automated test platform. The signal adapter unit integrates the lines, simplifies the installation process, and reduces wiring risks.

[0043] Specifically: The signal adapter unit uses a heavy-duty connector module 9, which efficiently integrates the analog signal lines of the entire signal unit to achieve precise docking with the main unit and DMI of the rail vehicle operation control equipment. It not only ensures the accuracy of signal transmission and the stability of power supply, but also greatly simplifies the on-site installation process with its integrated characteristics, significantly reduces the risk of wiring errors, and thus improves the overall installation efficiency of the equipment. In addition, the modular structure gives the integrated test system a high degree of flexibility, and the functional modules can be easily configured or expanded according to specific needs, which greatly facilitates daily maintenance and component replacement operations, ensuring that the rail vehicle operation control equipment can still operate reliably and be efficiently managed in complex environments.

[0044] The human-computer interaction module includes a display control unit 7, which is connected to the industrial computer. The display control unit includes a liquid crystal display screen and a keyboard and mouse. The mouse is used to operate the test interface and control the host computer software to perform the test. The liquid crystal display screen is used to display the test content and results.

[0045] Furthermore, the LCD display can be a touch display, and the test interface can be operated directly through the touch screen. The human-computer interaction module can be a fixed terminal connected to the industrial computer and PDU power supply through a cable, or it can be a mobile terminal wirelessly connected to the industrial computer through a communication module, and remotely controlled by the mobile terminal. In this case, the mobile terminal has its own power supply, which can be a lithium battery. When the human-computer interaction module is connected to the mobile terminal, a speaker and a microphone are provided on the mobile terminal, and voice control can be performed through the microphone, and voice broadcasts can also be performed through the speaker, and the broadcast content includes test progress, test results, etc.

[0046] The whole machine signal unit also includes a computer control module, etc. The fan unit is used to dissipate heat for the entire integrated test system.

[0047] The rail vehicle operation control equipment automated comprehensive test system provided in this embodiment can be realized in two forms: cabinet type and desktop type. When in use, it is necessary to ensure that the host or single board of the rail vehicle operation control equipment is correctly connected, and the test items are selected for testing using the host computer test software. When the whole machine test is selected, the whole machine signal unit simulates the conditional signal required by the rail vehicle operation control equipment, and collects the output signal, displays the test progress through the display control unit, saves the test results after the test is completed, and can query the test report through the data management function. When the single board test is selected, the single board test unit simulates the conditional signal required by the single board of the rail vehicle operation control equipment, and collects the output signal, displays the test progress through the display control unit, saves the test results after the test is completed, and can query the test report through the data management function. In this way, the automated test of the rail vehicle operation control equipment is realized, which can well help the management unit to conduct equipment inspection on the rail vehicle operation control equipment in the laboratory, and greatly promote the quality management and maintenance of the rail vehicle operation control equipment of the electrical management unit.

[0048] The automated comprehensive testing system for rail vehicle operation control equipment provided in this embodiment performs automated comprehensive testing on the hardware and software of the rail vehicle operation control equipment, and can realize testing of the entire machine and single board of the rail vehicle operation control equipment, thereby improving the efficiency of equipment inspection, testing and production, increasing the automation level of equipment testing, and reducing manual input during the testing process.

[0049] Embodiment three: This embodiment provides an automated comprehensive testing method for rail vehicle operation control equipment, which is applied to an automated comprehensive testing system for rail vehicle operation control equipment provided in the first or second embodiment.

[0050] like Figure 2 As shown, the comprehensive testing method includes: Step 1: Wiring self-check.

[0051] Perform a self-check on the wiring of the integrated test system to determine whether there is any abnormality. If there is no abnormality, proceed to the subsequent test steps. If there is an abnormality (such as communication abnormality), you need to manually check the wiring and deal with the wiring problem, and then perform a wiring self-check again until the wiring self-check passes.

[0052] Step 2: Choose to perform a single board test or a whole machine test of the rail vehicle operation control equipment.

[0053] By creating a new test item, you can choose to perform a single board test or a whole machine test of the rail vehicle operation control equipment.

[0056] 1) Select the test dual system.

[0057] The dual-system test uses two sets of hardware equipment, which in this embodiment include system A and system B. In the dual-system test, after testing one system, the system prompts to switch the system. After the testing of both systems is completed, the test ends.

[0058] Specifically: First, test the A system, compare the collected rail vehicle operation control device signal with the analog input signal, and determine whether it passes the test according to the inspection standard. If the A system test fails, determine whether to retest. If retest is not required, directly prompt to switch the system, perform manual switching, and switch to the B system test; if the A system test passes, prompt to switch the system, perform manual switching, and switch to the B system test.

[0059] If the B series test is qualified, the test is terminated; if the B series test is unqualified, determine whether to retest, and choose whether to retest the B series according to actual needs. If retesting is not required, the test is terminated. At the same time, when the B series or A series test fails (that is, the whole machine test fails), the faulty board information will be prompted, and the faulty board will be tested again separately, and the specific unqualified parts will be obtained through the single board test.

[0060] 2) Select the test line.

[0061] The single system is the basic configuration of the rail vehicle operation control equipment type operation monitoring device, which includes a set of hardware equipment. During the test, the information can be automatically input through the scanner, and the collected rail vehicle operation control equipment signal is compared with the simulated input signal, and the test is determined according to the inspection standard. The test ends after the single system test is passed. If the test fails, you can choose whether to retest. If not, the test ends. If retesting, the input signal is simulated again.

[0062] When the single board test fails, select the failed item and obtain the fault diagnosis result, which includes the troubleshooting suggestion of the failed item, the schematic diagram and physical diagram of the fault-related hardware.

[0063] Step 3: After the test is finished, save the test results.

[0064] After the test is completed, the test results are saved and a test report is generated. The test report includes the test items, test results and fault diagnosis results, the number of equipment tests, the number of faults, and troubleshooting for equipment with a large number of faults.
