Description

Technical Field

[0001] This invention relates to the field of computer automated testing technology, and in particular to an automated testing platform for railway computer interlocking products. Background Technology

[0002] During the testing of the station's computer interlocking products, after powering on the product under test, manual operation of the circuit breakers and switches of each device is required according to the commissioning and inspection manual. Then, a multimeter is used to measure the voltage and resistance at each test point, and the results are manually recorded in the commissioning and inspection record sheet. The product under test has a large number of test points: approximately 50 grounding resistance test points, approximately 15 sets of AC220V and AC110V test points, and approximately 2 sets of DC24V test points. Each driver board requires measurement of the drive voltage (DC24V), and each driver board has 32 sets of test points. The number of driver boards per product set is determined based on the project configuration, averaging about 20 boards per project, meaning an average of approximately 640 sets of DC24V test points per product set. For grounding resistance, AC220V, AC110V, and DC24V (non-driving voltage), the testing and commissioning instructions must be followed step-by-step, using a multimeter to measure each test point and record the results. For driving voltage testing, a standard testing setup has been set up, using a digital display module to show each driving voltage. Test personnel then record the specific voltage values ​​in a logbook. All test data requires manual judgment to determine if it meets the testing requirements. Therefore, the existing technology involves cumbersome testing procedures, relies heavily on manual judgment, has low testing efficiency, and carries a significant risk of misoperation and misjudgment. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an automatic testing platform for station computer interlocking products, which can effectively improve testing efficiency and reduce the risk of misjudgment.

[0004] The objective of this invention can be achieved through the following technical solutions:

[0005] This invention provides an automatic testing platform for station computer interlocking products, including a remote control module, a first switching control module, a second switching control module, a power supply module, and a first voltage acquisition module, a second voltage acquisition module, and a resistance acquisition module connected to the power supply module. The first voltage acquisition module is connected to the station computer interlocking product under test. The second voltage acquisition module and the resistance acquisition module are respectively connected to the station computer interlocking product under test through the first switching control module and the second switching control module. The remote control module is communicatively connected to the first voltage acquisition module, the second voltage acquisition module, the resistance acquisition module, the first switching control module, and the second switching control module.

The first voltage acquisition module includes multiple voltage acquisition units, some of which are connected to the voltage test point of the drive board, and others are connected to the DC24V voltage test point.

[0008] As a preferred technical solution, each voltage acquisition unit includes multiple sets of first voltage acquisition points, which are connected in groups to the voltage test points of the driver board and the DC24V voltage test points via test cables.

[0009] As a preferred technical solution, the voltage acquisition range of each voltage acquisition unit is DC 0-30V.

[0014] As a preferred technical solution, the first voltage acquisition module, the second voltage acquisition module, the resistance acquisition module, the first switching control module, and the second switching control module communicate with the remote control module via RS485.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. Compared with traditional manual testing, the automatic testing platform provided by this invention is equipped with a first voltage acquisition module, a second voltage acquisition module, and a resistance acquisition module, which are respectively connected to a remote control module and connected to the computer interlocking product of the station under test.

[0018] Figure 1 This is a schematic diagram of the automatic testing platform structure provided in an embodiment of the present invention;

[0019] The components include: 1. Remote control module; 2. First switching control module; 3. Second switching control module; 41. First power supply; 42. Second power supply; 5. First voltage acquisition module; 6. Second voltage acquisition module; and 7. Resistance acquisition module. Detailed Implementation

[0020] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. These embodiments are based on the technical solution of the present invention and provide detailed implementation methods and specific operating procedures. However, the scope of protection of the present invention is not limited to the following embodiments.

[0021] Example

[0022] like Figure 1As shown, this embodiment provides an automatic testing platform for station computer interlocking products. The testing platform includes a remote control module 1, a first switching control module 2, a second switching control module 3, a power supply module including a first power supply 41 and a second power supply 42, a first voltage acquisition module 5, a second voltage acquisition module 6, and a resistance acquisition module 7. In the figure, the thick black lines represent the power supply lines of the first power supply 41 and the second power supply 42 to the first voltage acquisition module 5, the second voltage acquisition module 6, and the resistance acquisition module 7; the thin black lines represent the test cables between the testing platform and the station computer interlocking product under test; and the dashed connecting lines represent the RS485 communication lines between the remote control module 1 and each acquisition module and each switching control module.

[0023] The first voltage acquisition module 5 includes four voltage acquisition units: a first voltage acquisition unit (DC30), a second voltage acquisition unit (DC30), a third voltage acquisition unit (DC30), and a fourth voltage acquisition unit (DC30). Each voltage acquisition unit (DC30) has nine voltage acquisition points (i.e., the first voltage acquisition points), capable of acquiring voltages between DC 0-30V. The first to fourth voltage acquisition units (DC30) acquire 32 drive voltages from the driver board and two sets of DC 24V voltage test points. Each voltage acquisition unit (DC30) is directly connected to the test point via a test cable.

[0024] The second voltage acquisition module 6 (AC220V) has 4 sets of voltage acquisition points (i.e., the second voltage acquisition points), which can acquire voltages between AC0-500V. For the 15 sets of AC220V voltage test points and AC110V voltage test points, they need to be measured separately through the first switching control module 2. The first switching control module 2 is directly connected to each test point through test cables.

[0025] The resistance acquisition module 7 has 8 resistance acquisition points, which can acquire resistances between 0.02Ω and 40MΩ. For the 50 grounding resistance test points, they need to be measured separately through the second switching control module 3, which is directly connected to each test point through a test cable.

[0026] Both the first power supply 41 (DC24V) and the second power supply 42 (DC24V) are AC220V to DC24V power modules. The first power supply 41 (DC24V) is connected to the first voltage acquisition module 5, providing DC24V operating power to the first to fourth voltage acquisition units (DC30); the second power supply 42 is connected to the second voltage acquisition module 6 and the resistance acquisition module 7, providing DC24V operating power to the resistance acquisition module 7 and the second voltage acquisition module 6 (AC220V).

[0027] The remote control module 1 is a computer equipped with dedicated testing software. The first switching control module 2, the second switching control module 3, the first voltage acquisition module 5, the second voltage acquisition module 6, and the resistance acquisition module 7 can communicate with the computer via RS485 serial port. The computer sends acquisition commands to each acquisition module and control commands to each switching control module. Each acquisition module will also upload the acquired data to the computer.

[0028] The computer-configured testing software is written in C# and uses the WinForms framework. It displays operation prompts based on the commissioning and testing requirements of the computer interlocking products at the station under test, such as "Close the A-line 220V circuit breaker," "Disconnect the I-series interlocking circuit breaker," and "Open the UPS A switch." After the tester follows the prompts and clicks "OK," the software automatically sends control and acquisition commands to each switching control module and acquisition module, and reads the data returned by the acquisition modules. The software categorizes and summarizes the acquired voltage and resistance data, compares it with pre-configured upper and lower limits in the database to determine if the data is qualified, and displays the final results on the monitor. After all tests are completed, the software can read a locally configured WORD format record form template, input all test results into the template, automatically generate a test report, and save it as a PDF file. Throughout the testing process, the software automatically executes the test procedures, controlling the acquisition and control modules of the automatic testing platform to collect and transmit data. For some steps that cannot be automatically controlled, manual completion is indicated by pop-up prompts (such as connecting cables or closing mechanical switches). The collected data (such as 220V voltage) is compared with the data in the software background and the locally stored database (the database requires voltage >210V and <230V). If the data meets the requirements, it is considered qualified.

[0029] Compared to traditional manual testing methods, the automated testing platform provided in this embodiment has the following advantages:

[0030] 1. Traditional testing methods involve using a multimeter to contact each test point individually. This method requires a large number of test points, carries the risk of poor contact between the probes, demands a steady and precise hand from the operator, results in low testing efficiency, and may lead to inaccurate test data. This testing platform connects the test cable to each test point and allows for automatic testing controlled by testing software. It offers reliable connections, ease of operation, and improves both testing efficiency and accuracy.

[0031] 2. Traditional testing methods require testers to manually record test data for each item tested, especially for drive voltage tests, which require recording a large amount of data and manually judging whether it is qualified. This is time-consuming and carries the risk of clerical errors and misjudgments. This testing platform automatically collects, records, judges, and generates test reports through testing software, improving testing efficiency and the accuracy of test results.

[0032] 3. Traditional testing methods involve testers meticulously reviewing the commissioning and inspection manual, which is typically quite lengthy. For example, the manual for the station computer interlocking equipment tested by this platform is nine pages long. Testers have to read and test simultaneously, resulting in low efficiency and the risk of misreading or missing information. This testing platform embeds the test content into the software, providing prompts to testers on each item, reducing workload and improving efficiency and accuracy.

[0033] In practical applications, traditional testing methods are cumbersome, requiring approximately 8 hours to test a set of station computer interlocking equipment. Using the testing platform provided in this embodiment, testing a set of station computer interlocking equipment takes approximately 2.5 hours, significantly reducing testing time and improving testing efficiency.

[0034] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
