Description

Technical Field

[0001] This invention relates to the field of testing technology for rail transit equipment, and in particular to a method, apparatus, equipment, and medium for testing the waterproof performance of vehicle components. Background Technology

[0002] In rail transit systems, external electrical components of rail vehicles refer to electrical equipment installed on the exterior of the vehicle body, exposed to the natural environment, and responsible for critical functions such as vehicle operation, signaling, communication, power supply, and safety. Their performance directly affects the stable operation of the entire system. Because external electrical components are constantly exposed to the outdoor environment, they are subject to corrosion from rain and humid air. If the waterproofing performance of these components is inadequate, moisture can penetrate them, potentially leading to decreased insulation performance, short circuits, and in severe cases, system malfunctions that compromise operational safety. Therefore, accurate and comprehensive testing of the waterproofing performance of external electrical components of rail vehicles is crucial.

[0003] Existing testing methods for the waterproof performance of external electrical components of rail vehicles have some shortcomings. Some methods only conduct simple water spray tests with limited testing conditions, failing to simulate the various complex aquatic environments that external electrical components may encounter during actual use. Other methods lack precise control and monitoring of key parameters during the testing process, resulting in low accuracy and reliability of the test results.

[0061] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0062] Existing methods for testing the waterproof performance of external electrical components of rail vehicles have some shortcomings. Some methods only involve simple water spray tests with limited testing conditions, failing to simulate the complex aquatic environments that external electrical components may encounter during actual use. Other methods lack precise control and monitoring of key parameters during the testing process, resulting in low accuracy and reliability of the test results. Therefore, this application discloses a method, apparatus, equipment, and medium for testing the waterproof performance of vehicle components, enabling a more comprehensive and accurate test of the waterproof performance of rail vehicle components.

[0063] See Figure 1 As shown in the figure, this application discloses a method for testing the waterproof performance of vehicle components, the method comprising:

[0064] Step S11: Identify the vehicle component to be tested and install it in the test box.

[0065] First, it should be noted that to perform waterproof performance testing on vehicle components, a corresponding waterproof performance testing device is required. This device specifically includes a test chamber, a water supply system, an air pressure regulation system, a temperature regulation system, a humidity regulation system, a monitoring system, and a control system. The test chamber houses the vehicle component under test; the water supply system provides water of different forms and pressures to the component within the chamber; the air pressure regulation system regulates the air pressure inside the chamber; the temperature regulation system regulates the temperature; the humidity regulation system regulates the humidity; the monitoring system monitors the status parameters of the component and the environmental parameters within the chamber; and the control system is electrically connected to the water supply system, air pressure regulation system, temperature regulation system, humidity regulation system, and monitoring system, and is used to control the operation of each system and process and analyze the data.

[0066] In this embodiment, the vehicle component to be tested is first determined. It should be noted that the vehicle component to be tested here mainly refers to the external electrical components of the rail vehicle, such as sensors, controllers, electrical switches, motors, etc. Further, the vehicle component to be tested needs to be securely mounted on a mounting bracket inside the test box, ensuring that the component is firmly installed and that its test surface faces the water spray direction of the water supply system. Simultaneously, monitoring sensors can be installed at preset locations inside the vehicle component to be tested. These monitoring sensors can specifically include humidity sensors, temperature sensors, and insulation resistance sensors, etc., to measure the state parameters of the vehicle component to be tested, and these sensors are electrically connected to the monitoring system. After the installation of the monitoring sensors is completed, the initial state parameters of the vehicle component to be tested can be monitored through the monitoring system. The type of state parameters is consistent with the type of monitoring sensors, including internal humidity, internal temperature, and insulation resistance.

[0067] In a specific implementation, installing the vehicle component under test into the test chamber includes: performing a pre-inspection process on the vehicle component under test; wherein the pre-inspection process includes visual inspection, cleaning, and drying; and then installing the pre-inspected vehicle component under test into the test chamber. It is understood that before installing the vehicle component under test into the test chamber, pre-inspection processes such as visual inspection, cleaning, and drying can be performed on the vehicle component under test to eliminate interference factors, standardize test benchmarks, and ensure stable component testing conditions before installing the pre-inspected vehicle component into the test chamber.

[0068] For example, a visual inspection of the vehicle components to be tested can be performed first to ensure that their surfaces are free of obvious damage, cracks, or other defects, avoiding the inclusion of inherently unqualified components in the testing process and reducing the waste of testing resources. Next, the vehicle components to be tested should be cleaned to remove dust, oil, and other impurities from their surfaces. This is because these impurities may clog seals, affect the contact between water and the component surface, or be washed away by water flow during testing, interfering with the judgment of whether there is water leakage. Pre-treatment ensures consistency between the testing environment and the component surface. Finally, the vehicle components to be tested should be placed in a dry environment for pre-treatment (i.e., static placement) at a temperature of 25-30℃ for 24-48 hours. This effectively removes residual moisture from the components and balances the internal temperature, preventing abnormal changes in state parameters (such as internal humidity) during testing due to uneven initial internal humidity or temperature fluctuations. This ensures that all components to be tested enter the testing process with a uniform initial baseline, improving the comparability of test results for different components and batches.

[0069] Step S12: Based on the preset multi-environment test process, send corresponding control commands to the environmental simulation system in sequence to generate the corresponding simulated test environment in the test chamber, so as to perform waterproof performance test on the vehicle component under test in the simulated test environment, and obtain the status parameters of the vehicle component under test after each test process; wherein, the multi-environment test process includes a preset rain test process, a preset high-pressure water impact test process, a preset humid environment test process, and a preset temperature change environment test process in sequence.

[0070] In this embodiment, to more comprehensively simulate the various complex water environments and climatic conditions that the vehicle components under test may encounter during actual use, making the testing more comprehensive and realistic, this application pre-sets a multi-environment testing process. This process sequentially includes a preset rain test, a preset high-pressure water impact test, a preset humid environment test, and a preset temperature change environment test. Then, based on the multi-environment testing process, corresponding control commands are sent to the environmental simulation system to generate corresponding simulated test environments in the test chamber. This allows for waterproof performance testing of the vehicle components under test within these simulated environments, and the state parameters of the vehicle components are acquired after each test process. In other words, by sequentially setting up multi-environment testing processes—rain test, high-pressure water impact test, humid environment test, and temperature change environment test—the various complex waterproof challenges that vehicle components may encounter in actual use are comprehensively covered. Compared to single-environment testing, this more realistically reproduces the component's operating conditions, ensuring that the evaluation results are more consistent with actual application scenarios and providing a reliable basis for component quality judgment.

[0071] Step S13: Evaluate the waterproof performance of the vehicle component under test based on the state parameters after the end of each test process to obtain the evaluation result.

[0072] In this embodiment, after each test process, the waterproof performance of the vehicle component under test must be evaluated based on the state parameters to obtain the corresponding evaluation results.

[0073] Among them, the state parameters include the internal humidity, internal temperature, and insulation resistance of the vehicle component to be tested; correspondingly, the waterproof performance of the vehicle component to be tested is evaluated based on the state parameters after each test process to obtain an evaluation result, including: determining whether the internal humidity, internal temperature, and insulation resistance after each test process exceed the corresponding preset thresholds respectively; if none of them exceed, it is determined that the evaluation result of the waterproof performance of the vehicle component to be tested is qualified, otherwise it is unqualified. It can be understood that through the foregoing content, it can be known that in the embodiment of the present application, a humidity sensor, a temperature sensor, and an insulation resistance sensor are pre-installed at preset positions inside the vehicle component to be tested. Therefore, the monitoring system can monitor state parameters such as the internal humidity, internal temperature, and insulation resistance of the vehicle component to be tested, and then compare the monitored state parameters with the corresponding preset thresholds. When the state parameters do not exceed the preset thresholds, it can be considered that the evaluation result of the waterproof performance of the vehicle component to be tested is qualified. If any one of the state parameters exceeds the corresponding preset threshold, it is considered that its waterproof performance is unqualified. In the specific implementation manner, if during the test process, the internal humidity of the vehicle component to be tested does not exceed the preset threshold, the insulation resistance does not show an obvious decrease, and there is no water seepage or leakage phenomenon, it is determined that the waterproof performance of the vehicle component to be tested is qualified; otherwise, it is determined to be unqualified. It should be noted that the preset thresholds are mainly determined according to the design requirements and usage environment of the vehicle component to be tested. For example, the preset threshold corresponding to the internal humidity can be set to 60%, and the preset threshold corresponding to the insulation resistance can be set to 100 MΩ.

[0074] Step S14: If the evaluation result indicates that the waterproof performance of the vehicle component to be tested is qualified, execute the next test process until all the multi-environment test processes are completed. If the evaluation result indicates that the waterproof performance of the vehicle component to be tested is unqualified, stop executing the subsequent test processes.

[0075] In this embodiment, the waterproof performance is evaluated based on the state parameters after each test process. Only when it is qualified can it enter the next test process until all the multi-environment test processes are completed. If it is unqualified, the subsequent tests are immediately stopped. By this means, the continuous execution of ineffective test processes can be avoided, the test cycle can be significantly shortened, the energy consumption, equipment wear, and additional damage of components during the test can be reduced, the test cost can be lowered, and at the same time, it is also convenient to quickly lock the failure node and provide an accurate direction for the analysis of the failure cause.

[0076] Furthermore, the above method also includes: after all the multi-environment test procedures are completed, removing the vehicle component under test from the test chamber and placing it in a preset dry environment, and after waiting for a preset time interval, obtaining the final state parameters of the vehicle component under test; evaluating the waterproof performance of the vehicle component under test based on the final state parameters, obtaining a final evaluation result, and determining whether the waterproof performance of the vehicle component under test is qualified based on the final evaluation result. It is understood that after all test procedures are completed, the vehicle component under test needs to be removed from the test chamber and placed in a dry environment for 24-48 hours. Then, its final state parameters, including internal humidity, internal temperature, and insulation resistance, are monitored by a monitoring system, and relevant data are recorded. The final state parameters are then compared with corresponding preset thresholds to evaluate the waterproof performance of the vehicle component under test, thereby obtaining a final evaluation result, and determining whether the waterproof performance of the vehicle component under test is qualified based on the final evaluation result. It should be noted that if the initial state parameters, the state parameters of each test stage, and the final state parameters are all within the preset thresholds, the waterproof performance of the vehicle component under test can be determined to be qualified; otherwise, it is determined to be unqualified.

[0077] As can be seen, this method comprehensively covers various complex waterproof challenges that vehicle components may encounter in actual use by sequentially setting up multi-environment testing procedures, including rain testing, high-pressure water impact testing, humid environment testing, and temperature change environment testing. Compared with single-environment testing, it can more realistically reproduce the operating conditions of components, ensuring that the evaluation results are more in line with actual application scenarios and providing a reliable basis for component quality judgment. Furthermore, this application evaluates waterproof performance based on state parameters after each test procedure; only those that pass the evaluation proceed to the next procedure, while those that fail immediately stop subsequent testing. This approach avoids the continuation of invalid testing procedures, significantly shortens the testing cycle, reduces energy consumption, equipment wear and tear, and additional component damage during testing, lowers testing costs, and also facilitates rapid identification of failure points, providing precise direction for failure cause analysis.

[0078] See Figure 2 As shown, this application discloses a specific method for testing the waterproof performance of vehicle components. Compared to the previous embodiment, this embodiment further explains and optimizes the technical solution. Specifically, it includes:

[0079] Step S21: Identify the vehicle component to be tested and install it in the test box.

[0080] Step S22: Based on the test sequence in the preset multi-environment test process, determine the current test process and send the control command corresponding to the current test process to the environment simulation system to generate a simulated test environment under the current test process in the test chamber; wherein, the multi-environment test process includes a preset rain test process, a preset high-pressure water impact test process, a preset humid environment test process, and a preset temperature change environment test process in sequence, and the environment simulation system includes at least a water supply system, a temperature regulation system, and a humidity regulation system, which are used to simulate preset environmental parameters in the test chamber respectively.

[0081] In this embodiment, the multi-environment testing process, in the order of testing, includes a preset rain test process, a preset high-pressure water impact test process, a preset humid environment test process, and a preset temperature change environment test process. Therefore, this application needs to determine the current test process according to the test order and send control commands corresponding to the current test process to the environmental simulation system to generate a simulated test environment under the current test process in the test chamber. It should be noted that the environmental simulation system includes at least a water supply system, a temperature control system, and a humidity control system, used to simulate the corresponding preset environmental parameters in the test chamber, that is, to simulate the working conditions that the vehicle components under test may encounter in actual operation.

[0082] In a specific implementation, the current test process is a preset rain test process; wherein, the preset rain test process includes preset light rain test stage, moderate rain test stage, and heavy rain test stage, and the test time corresponding to different test stages is different; accordingly, sending control instructions corresponding to the current test process to the environmental simulation system to generate a simulated test environment under the current test process in the test box includes: based on the time interval between different test stages in the preset rain test process, sequentially sending control instruction sets corresponding to the light rain test stage, the moderate rain test stage, and the heavy rain test stage to the target simulation system in the environmental simulation system, so as to sequentially generate a simulated test environment under the light rain test stage, the moderate rain test stage, and the heavy rain test stage in the test box; wherein, the target simulation system includes the water supply system, the temperature control system, and the humidity control system, and the control instruction set includes spray pressure control instructions and spray flow control instructions sent to the water supply system, temperature control instructions sent to the temperature control system, and humidity control instructions sent to the humidity control system.

[0083] In other words, when the current testing process is a preset rain test process, the preset rain test process specifically includes preset light rain test stages, moderate rain test stages, and heavy rain test stages, and the test time corresponding to each test stage is different. It should be noted that during the rain test, the water supply system, temperature regulation system, and humidity regulation system need to be controlled by the control system to operate in coordination to simulate different rain conditions for testing the vehicle components under test. Correspondingly, the control command set sent to the environmental simulation system includes water spray pressure control commands and water spray flow control commands sent to the water supply system, temperature control commands sent to the temperature regulation system, and humidity control commands sent to the humidity regulation system. Among them, the rain test process includes the following stages in the test sequence, and in each test stage, the internal humidity, internal temperature, and insulation resistance of the vehicle components under test will be monitored and recorded in real time by the monitoring system:

[0084] Phase 1: Light rain test phase. The water supply system spray pressure is controlled at 0.1-0.2MPa, the spray flow rate is 5-10L / min, the temperature inside the test chamber is controlled at 0-25℃ through the temperature control system, and the relative humidity inside the test chamber is controlled at 60-70% through the humidity control system. The test time is 2-4 hours.

[0085] Phase Two: Moderate Rain Test Phase. The water supply system spray pressure is controlled at 0.3-0.4MPa, the spray flow rate is 15-20L / min, the temperature inside the test chamber is controlled at 15-20℃ through the temperature control system, and the relative humidity inside the test chamber is controlled at 70-80% through the humidity control system. The test time is 4-6 hours.

[0086] Phase 3: Heavy rain test phase. The water supply system spray pressure is controlled at 0.5-0.6MPa, the spray flow rate is 25-30L / min, the temperature inside the test chamber is controlled at 10-15℃ through the temperature control system, and the relative humidity inside the test chamber is controlled at 80-90% through the humidity control system. The test time is 6-8 hours.

[0087] In a specific implementation, the current test procedure is a preset high-pressure water impact test procedure; correspondingly, sending control commands to the environmental simulation system corresponding to the current test procedure to generate a simulated test environment under the current test procedure in the test chamber includes: sending water pressure control commands, water flow control commands, impact distance control commands, and impact time control commands corresponding to the preset high-pressure water impact test procedure to the water supply system to generate a simulated test environment under the preset high-pressure water impact test procedure in the test chamber.

[0088] Understandably, after the rain test, a preset high-pressure water impact test procedure is executed. Therefore, if the current test procedure is the preset high-pressure water impact test procedure, the water supply system needs to be controlled by the control system to perform the high-pressure water impact test on the vehicle component under test. Accordingly, the instructions sent to the water supply system specifically include water spray pressure control instructions, water spray flow control instructions, impact distance control instructions, and impact time control instructions to generate a simulated test environment under the preset high-pressure water impact test procedure in the test chamber. In a specific implementation, the water spray pressure of the water supply system can be controlled at 1.0-1.5 MPa, the water spray flow rate at 30-40 L / min, and the distance between the high-pressure water nozzle and the test surface of the vehicle component under test at 0.5-1 m. Impacts are applied to different parts of the vehicle component under test, with each part impacted for 30-60 seconds. During the test, the internal humidity, internal temperature, and insulation resistance of the vehicle component under test are monitored and recorded in real time by the monitoring system.

[0089] In a specific implementation, the current test process is a preset humid environment test process; correspondingly, sending control commands to the environmental simulation system corresponding to the current test process to generate a simulated test environment under the current test process in the test chamber includes: sending temperature control commands and humidity control commands corresponding to the preset humid environment test process to the temperature control system and the humidity control system respectively, so as to generate a simulated test environment under the preset humid environment test process in the test chamber for a preset duration.

[0090] In this embodiment, after the high-pressure water impact test, a preset humid environment test procedure is further executed. Therefore, if the current test procedure is the preset humid environment test procedure, the water supply system needs to be stopped by the control system, while the temperature and humidity control systems continue to operate to conduct a humid environment test on the vehicle component under test. Accordingly, temperature control commands and humidity control commands are sent to the temperature and humidity control systems respectively to generate a simulated test environment under the preset humid environment test procedure in the test chamber, and this environment is maintained for a preset duration. In a specific implementation, the temperature inside the test chamber can be adjusted to 30-40°C and the relative humidity to 90-95% by the temperature and humidity control systems, and this environmental condition can be maintained for 12-24 hours. During the test, the internal humidity, internal temperature, and insulation resistance of the vehicle component under test are monitored and recorded in real time by the monitoring system.

[0091] In a specific implementation, the current test process is a preset temperature change environment test process; correspondingly, sending a control command corresponding to the current test process to the environment simulation system to generate a simulated test environment under the current test process in the test chamber includes: sending a temperature control command corresponding to the preset temperature change environment test process to the temperature regulation system; wherein, the temperature control command is used to control the temperature in the test chamber to change periodically within a preset temperature change range based on a preset time period.

[0092] In this embodiment, after the humid environment test, a preset temperature change environment test procedure is further executed. Therefore, if the current test procedure is the preset temperature change environment test procedure, the temperature regulation system needs to be controlled by the control system to conduct temperature change environment tests on the vehicle components under test. Accordingly, this embodiment needs to send a temperature control command to the temperature regulation system. This command is mainly used to control the temperature inside the test chamber to change periodically within a preset temperature change range based on a preset time period. That is, after the humid environment test, this application controls the temperature inside the test chamber to change periodically through the temperature regulation system. The temperature change range is -10-50℃, and each cycle lasts 8-12 hours, with the low temperature stage and the high temperature stage each accounting for half of the time. During the test, the status parameters of the vehicle components under test are monitored and recorded in real time by the monitoring system. Finally, a total of 3-5 cycles of testing are performed.

[0093] Furthermore, the above method also includes: continuously monitoring the current environmental parameters within the test chamber; determining the deviation between the current environmental parameters and the target parameter value corresponding to the control command; and if the deviation exceeds a preset deviation threshold, adjusting the operating parameters of the environmental simulation system to keep the environmental parameters within the test chamber within a preset range. It is understood that during simulated rain testing, high-pressure water impact testing, humid environment testing, and temperature change environment testing, the monitoring system continuously monitors the environmental parameters within the test chamber, and the control system can adjust the operating parameters of each system in real time based on the environmental parameters fed back by the monitoring system. Specifically, by comparing the monitored current environmental parameters with the target parameter value corresponding to the control command, if the deviation between the two exceeds a preset deviation threshold, the operating parameters of the environmental simulation system are adjusted to keep the environmental parameters within the test chamber within a preset range. For example, suppose that during a rain test, the target parameters corresponding to the control command are: water spray pressure of 0.35 MPa, chamber temperature of 18°C, and chamber humidity of 75%RH. However, after 3 hours of continuous water spraying, the actual pressure drops to 0.3 MPa due to pump wear, while the humidity inside the chamber rises to 80%RH due to moisture accumulation. At this point, the control system needs to send a command to the high-pressure water pump of the water supply system to increase the motor power and raise the pressure back to 0.35 MPa. At the same time, the dehumidifier is activated to reduce the humidity inside the chamber to within the range of 75%RH ± 3% to avoid affecting the accuracy of the test due to excessive humidity.

[0094] Furthermore, it should be noted that the water supply system includes a water tank, a water pump, water pipes, and nozzles. The water pump is used to transport water from the water tank to the nozzles through the water pipes. There are multiple nozzles, and the spray direction and angle are adjustable. That is, the water supply system mainly consists of a water tank, a water pump, water pipes, and nozzles; the water tank serves as a water storage unit; the water pump can be a variable frequency high-pressure water pump, which can achieve stepless speed regulation and accurately match the preset spray pressure according to the pressure requirements of different test processes (such as light rain test, high-pressure water impact test); the water pipes can be high-pressure wear-resistant rubber hoses; the nozzles serve as water output terminals, and the number can be configured to be 4-8, evenly distributed on the top and sides of the test chamber, covering the entire test surface of the component under test. Each nozzle is equipped with a 360° rotatable adjustment base and an angle adjustment knob, which can flexibly adjust the spray direction (horizontal, vertical, tilt, etc.) and spray angle (0°-180°), and can simulate different rainfall angles, high-pressure water impact directions, and other actual scenarios. In practice, the water pump is used to transport water from the water tank to the nozzles through water pipes.

[0095] Furthermore, the environmental simulation system also includes an air pressure regulation system; the air pressure regulation system includes a vacuum pump and an air pressure sensor. The vacuum pump is used to evacuate or inflate the test chamber, and the air pressure sensor is used to monitor the air pressure inside the test chamber. That is, the environmental simulation system in this application may also include an air pressure regulation system. This system, as a core component simulating air pressure changes during vehicle operation, works in conjunction with the temperature and humidity regulation systems to precisely control the air pressure environment inside the test chamber, providing more realistic simulation conditions for waterproof performance testing. The air pressure regulation system mainly includes a vacuum pump and an air pressure sensor to collaboratively achieve dynamic adjustment and stable monitoring of air pressure. The vacuum pump can be an oil-free high-vacuum pump, which can perform vacuuming operations inside the test chamber according to testing requirements, simulating the vehicle's operation in a high-altitude, low-pressure environment. The air pressure sensor can be a high-precision digital sensor to capture subtle changes in air pressure inside the test chamber in real time and transmit the data synchronously to the control system.

[0096] Furthermore, the multi-environment testing process also includes an air pressure testing process; correspondingly, sending a control command corresponding to the current testing process to the environmental simulation system to generate a simulated testing environment under the current testing process in the test chamber includes: sending an air pressure control command corresponding to the air pressure testing process to the air pressure regulation system to generate a simulated testing environment under the air pressure testing process in the test chamber; wherein, the air pressure control command is used to adjust the air pressure in the test chamber to a preset value lower than the standard atmospheric pressure. That is, considering that the external air pressure will decrease when the train passes through tunnels or high-altitude areas, if the component is sealed with air, a pressure difference will be generated inside and outside when the external air pressure decreases (internal air pressure > external air pressure). This positive pressure difference will push the internal air (which may carry moisture) outward to find a leak point, and may even aggravate existing minor leaks. Therefore, this application can also superimpose a low-pressure holding stage after the temperature change test or humid environment test to check whether the component can still remain sealed under the internal positive pressure state. Therefore, this application can send a pressure control command corresponding to the pressure test process to the pressure regulation system. The pressure control command is used to adjust the pressure in the test chamber to a preset value lower than the standard atmospheric pressure, that is, to maintain a low pressure stage, so as to simulate the low pressure environment under high altitude or high speed operation, while monitoring the internal status parameters of the components.

[0097] Step S23: Perform a waterproof performance test on the vehicle component under test in the simulated test environment, and obtain the status parameters of the vehicle component under test after each test process.

[0098] In this embodiment, the waterproof performance of the vehicle component under test is tested under the test environments corresponding to the rain test process, high-pressure water impact test process, humid environment test process, temperature change environment test and air pressure test, and the status parameters of the vehicle component under test are obtained after each test process.

[0099] In addition, the monitoring system may also include an image acquisition device for real-time imaging of the surface of the vehicle parts under test to observe whether there is water seepage or leakage.

[0100] Step S24: Evaluate the waterproof performance of the vehicle component under test based on the state parameters after the end of each test process to obtain the evaluation result.

[0101] Step S25: If the evaluation result indicates that the waterproof performance of the vehicle component under test is qualified, then proceed to the next test procedure until all the multi-environment test procedures are completed. If the evaluation result indicates that the waterproof performance of the vehicle component under test is unqualified, then stop executing the subsequent test procedures.

[0103] As can be seen, this application, by setting up multiple testing stages, including simulated rain testing, high-pressure water impact testing, humid environment testing, and temperature change environment testing, can comprehensively simulate various complex water environments and climatic conditions that external electrical components of rail vehicles may encounter during actual use, making the testing more comprehensive and realistic. Furthermore, by employing a monitoring system, this application can monitor key state parameters such as internal humidity, temperature, and insulation resistance of the external electrical components of rail vehicles in real time during the testing process, while precisely controlling the environmental parameters within the test chamber, thus improving the accuracy and reliability of the test results. Through the above scheme, the waterproof performance of external electrical components of rail vehicles can be comprehensively and accurately tested, providing a reliable basis for the quality assessment and improvement of external electrical components of rail vehicles.

[0104] See Figure 3 As shown in the figure, this application discloses a device for testing the waterproof performance of vehicle components. The device includes:

[0105] Mounting module 11 is used to identify the vehicle component under test and install the vehicle component under test into the test box;

[0106] Test module 12 is used to send corresponding control commands to the environmental simulation system sequentially based on a preset multi-environment test process to generate a corresponding simulated test environment in the test chamber, so as to perform waterproof performance testing on the vehicle component under test in the simulated test environment, and obtain the status parameters of the vehicle component under test after each test process; wherein, the multi-environment test process sequentially includes a preset rain test process, a preset high-pressure water impact test process, a preset humid environment test process, and a preset temperature change environment test process;

[0107] Evaluation module 13 is used to evaluate the waterproof performance of the vehicle component under test based on the state parameters after the end of each test process, so as to obtain the evaluation result;

[0108] The result determination module 14 is used to execute the next test process if the evaluation result indicates that the waterproof performance of the vehicle component under test is qualified, until all the multi-environment test processes are completed; if the evaluation result indicates that the waterproof performance of the vehicle component under test is unqualified, the subsequent test processes are stopped.

[0109] As can be seen, this method comprehensively covers various complex waterproof challenges that vehicle components may encounter in actual use by sequentially setting up multi-environment testing procedures, including rain testing, high-pressure water impact testing, humid environment testing, and temperature change environment testing. Compared with single-environment testing, it can more realistically reproduce the operating conditions of components, ensuring that the evaluation results are more in line with actual application scenarios and providing a reliable basis for component quality judgment. Furthermore, this application evaluates waterproof performance based on state parameters after each test procedure; only those that pass the evaluation proceed to the next procedure, while those that fail immediately stop subsequent testing. This approach avoids the continuation of invalid testing procedures, significantly shortens the testing cycle, reduces energy consumption, equipment wear and tear, and additional component damage during testing, lowers testing costs, and also facilitates rapid identification of failure points, providing precise direction for failure cause analysis.
