[0065] S1. Obtain the status of the traction electric control test equipment preset in the locomotive.

[0066] In an embodiment of the present invention, before the traction electric brake test starts, the state of the traction electric brake test equipment is checked, and it is determined based on the detection result whether the state of the traction electric brake test equipment meets the preset test conditions.

[0067] Obtaining the status of the traction electric test equipment preset in the locomotive, the inspection of the traction electric test equipment can ensure that the traction electric test equipment operates in the best state, thereby improving the accuracy and reliability of the test, reducing the risk of failure, ensuring the validity of the data, and providing a reliable basis for subsequent analysis.

[0068] Figure 2 A data flow diagram of a railway locomotive traction electric brake test method provided in an embodiment of the present application, wherein ATO: intelligent driving system, HMI: driver's cab microcomputer display unit, CCU: central control unit, BCU: brake unit, such as Figure 2 As shown:

[0069] If the state of the traction electric brake test equipment does not meet the preset test conditions, corresponding processing is performed according to different situations and then the process returns to S1.

[0070] Different situations are divided into hardware failure of the traction electric control test equipment that requires manual intervention and the traction electric control test equipment that can automatically handle the problem. Manual intervention is required, such as iron shoe failure, module failure, etc., and the problem can be automatically handled, such as automatically applying small gate pressure, there are safety hazards to people ahead, etc.

[0071] If the state of the traction electric brake test equipment meets the preset test conditions, S2 is executed to perform the preset traction electric brake test in a preset order to obtain test data.

[0072] In an embodiment of the present invention, performing a preset traction brake test in a preset order to obtain test data includes:

[0073] forming a control instruction according to the preset traction force parameters and the preset electric brake parameters in the traction electric brake test;

[0074] Using a preset intelligent driving system to receive and process the control instruction to obtain an execution instruction;

[0075] Using the intelligent driving system to perform real-time detection on the train pipe and brake cylinder pressure in the traction electric brake test equipment to obtain real-time detection data;

[0076] When the real-time detection data meets the preset abnormal condition, the intelligent driving system sends a preset brake instruction to the preset brake unit;

[0077] Utilizing a preset central control unit to execute the execution instruction and obtain the execution status;

[0078] Feeding back the real-time detection data and the execution status to a preset microcomputer display unit in the driver's cab;

[0079] Convert the real-time detection data and the execution status into voice and broadcast them to the preset test personnel;

[0080] The test data of the traction electric brake test is received through the microcomputer display unit in the driver's cab.

[0081] In detail, the intelligent driving system is used to perform real-time detection on the train pipe and brake cylinder pressure in the traction electric brake test equipment to obtain real-time detection data, including:

[0082] Extracting the train pipe pressure value and the brake cylinder pressure value in the traction electric brake test equipment;

[0083] The train pipe pressure value and the brake cylinder pressure value are standardized to obtain real-time detection data;

[0084] If the train pipe pressure value in the real-time detection data is greater than the preset train pipe pressure threshold, or the brake cylinder pressure value in the real-time detection data is less than the preset brake cylinder pressure threshold, an abnormal instruction is fed back through the intelligent driving system;

[0085] If the train pipe pressure values ​​in the real-time detection data are all smaller than the train pipe pressure threshold, and the brake cylinder pressure values ​​in the real-time detection data are all larger than the brake cylinder pressure threshold, then continue to extract the train pipe pressure value and brake cylinder pressure value in the traction electric brake test equipment.

[0086] By real-time monitoring of the pressure data of the train pipes and brake cylinders in the traction electric brake test equipment, abnormal situations can be identified in a timely manner to ensure the comparability and accuracy of the data. By setting the pressure threshold, it can automatically determine whether the pressure is abnormal, thereby improving the safety and reliability of the system, improving the efficiency of detection, and enhancing the safety of train operation.

[0087] In detail, the execution instruction is executed by a preset central control unit to obtain the execution status, including:

[0088] Parsing the execution instruction to obtain key operation parameters;

[0089] Executing the locomotive according to the key operating parameters to obtain an execution status;

[0090] If the execution condition meets the preset failure condition, an alarm message is sent to the tester;

[0091] If the execution status meets the preset success conditions, the test data will be sent to the microcomputer display unit in the driver's cab.

[0092] By parsing the execution instructions and extracting the key operating parameters, the locomotive can be precisely controlled. After successful execution, the test data will be directly transmitted to the microcomputer display unit in the driver's cab, which improves the timeliness and transparency of information feedback. If the execution fails, the system can immediately send an alarm message to the test personnel to ensure rapid response and processing.

[0093] In detail, the step of converting the real-time detection data and the execution status into voice broadcast to a preset tester includes:

[0094] Extracting text key features of the real-time detection data and the execution status;

[0095] Converting the key features of the text into structured text information;

[0096] Converting the text information into speech through text-to-speech technology;

[0097] The voice is broadcast to the test personnel.

[0098] In the embodiment of the present invention, by extracting key features of real-time detection data and execution status, converting the text key features into structured text information, and converting it into speech using text-to-speech technology, efficient transmission of information can be achieved, which not only improves the clarity and comprehensibility of the information, but also can promptly feedback important information to the test personnel, helping them to make decisions and deal with problems quickly, thereby enhancing the safety and efficiency of locomotive operations.

[0099] In detail, the test personnel controls the start and end of the test through the display of the microcomputer display unit in the driver's cab, and understands the traction electric brake test process and the status of the locomotive through the display. When the control command is sent to the intelligent driving system through the display, the intelligent driving system sends the test data and results to the microcomputer display unit in the driver's cab to inform the test personnel. When the real-time detection data is abnormal, the preset brake command is sent to the preset brake unit through the intelligent driving system, and the train pipe and brake cylinder pressure in the traction electric brake test equipment are fed back to the intelligent driving system in real time. When the traction electric brake test is completed, a completion command is sent to the microcomputer display unit in the driver's cab.

[0100] The intelligent driving system achieves efficient control and monitoring, ensures the safety and accuracy of the traction brake test, obtains and feedbacks test data and execution status in real time, and enables test personnel to respond in time and handle potential abnormal situations. The effective flow of information between systems reduces human errors and improves operational efficiency. At the same time, automated monitoring and control command transmission simplifies the test process, improves overall operational reliability, and ensures that the test can be completed smoothly.

[0101] When the speed of the locomotive in the test data is less than a preset speed threshold, or the actual exertion of the locomotive is less than a preset traction force threshold, the process returns to S2.

[0102] When the speed of the locomotive in the test data is greater than or equal to a preset speed threshold, or the actual exertion of the locomotive is greater than or equal to a preset traction force threshold, S3 is executed to take measures of unloading traction for the locomotive.

[0103] In an embodiment of the present invention, the speed and the actual force exerted by the shaft in the test data are obtained, and the speed and the actual force exerted by the shaft are monitored in real time. When the speed of the locomotive in the test data is greater than or equal to a preset speed threshold, or the actual force exerted by the locomotive is greater than or equal to a preset traction threshold, an instruction to unload traction is sent to the tester.

[0104] By monitoring the speed of the locomotive and the actual force of each axle in real time, the safety and effectiveness of the test are ensured. When the speed or traction force exceeds the threshold, the unloading instruction is issued in time to prevent potential risks and ensure the safety of equipment and test personnel. At the same time, continuous acquisition and statistical data will help optimize test parameters and improve locomotive performance, and enhance the reliability and accuracy of the overall test.

[0105] S4. Generate a performance report of the locomotive using the actual exertion of the locomotive in the test data.

[0106] In an embodiment of the present invention, the step of generating a performance report of the locomotive using the actual exertion of the locomotive in the test data includes:

[0107] The performance level of the traction control test is divided according to the test data using the following formula:

[0108] ΔF 1 =β 1 (|F t1 -F r1 |)+α 1 +V 1

[0109] α 1 =(T 1 +P1 +H 1 )m

[0110] Among them, β 1 represents the correction parameters for different locomotive types, F r1 Indicates the preset traction force, F r1 Indicates the actual traction force, α 1 Represents the environmental factor correction parameter, V 1 Indicates the grid voltage fluctuation correction parameter, T 1 represents the temperature correction parameter, P 1 Represents humidity correction parameter, H 1 represents the altitude correction parameter, and m represents the environmental factor weight parameter;

[0111] The performance report of the prime traction control test is generated using the following formula based on the results of the performance level classification:

[0112]

[0113] Where, ΔF n Indicates the performance of axis n, where n is the number of axes.

[0114] By classifying the traction electrical test data into performance levels, the accuracy and fairness of the evaluation are ensured. The generated performance report will clearly define the performance of each axle, help identify the strengths and weaknesses of the locomotive, provide data support for subsequent optimization and improvement, and improve the operating efficiency of the locomotive.
