Description

TECHNICAL FIELD

[0001] The present application relates to the field of rail transit technology, and in particular to a rail transit power supply device testing method and device. BACKGROUND

[0002] A rail transit system usually contains multiple independent operating lines, each line covers 10-30 stations (the number of stations of a main line in some cities can reach more than 40), and each station needs to be configured with 3-8 power supply devices of different types (such as DC screens, UPS power supplies, and emergency power supplies, etc.), and the total number of power supply devices in the entire line often reaches hundreds. In order to ensure that the power supply device can stably supply power to the rail vehicle, the power supply device needs to be simulated tested, and the traditional simulation testing method requires the test personnel to manually write the message of the power supply device. The test personnel needs to manually write test messages in accordance with specific protocols for each power supply device of each station, and the preparation of single-station device messages takes about 15-30 minutes, and the whole line testing period is as long as several weeks, and the testing efficiency is low. When manually preparing test messages, the test results are prone to distortion due to input deviation of the number of power supply devices, non-standard format (such as calculation error of check bits), etc., and the error rate can reach 10%-15%. Manual testing is difficult to quickly switch between multiple test scenarios such as "normal operation", "fault alarm", and "voltage fluctuation", and cannot comprehensively verify the response capability of the power supply device under extreme working conditions. Moreover, after manually preparing the test messages, the test messages are manually sent to the test server to simulate test the power supply device.

[0003] It can be seen that when there are many lines, stations, and power supply devices in each station, the traditional manual testing leads to low testing efficiency of the power supply device and is prone to errors. SUMMARY

[0006] According to the rail transit power supply device testing method provided by the present application, the power supply device configuration file is read, which comprises: Based on the file path and the file name input by the user, a power supply device configuration file corresponding to the file name is read under a folder corresponding to the file path.

[0019] Figure 3 This is a schematic diagram of the structure of the electronic device provided by the present invention. Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0021] This invention provides a testing method for rail transit power supply equipment. This method can be implemented using a script program to automatically generate test messages for the power supply equipment. The specific flow of the method is as follows: Figure 1 As shown, it includes steps S110 to S130.

[0022] Step S110: Read the power supply device configuration file to obtain the configuration information of the power supply device. The power supply device configuration file contains configuration information for at least one power supply device. The configuration information of the power supply device includes: power supply device type, power supply device ID, power supply device name, device status (fault, normal), analog quantities (current, voltage, frequency), and switching quantities (contactor open, closed), etc. Specifically, the corresponding configuration information can be obtained by reading the keywords corresponding to the configuration information.

[0023] Step S120: Based on the power supply device type in the configuration information, generate test messages for each power supply device. Different power supply device types require different test messages, including: device status messages, analog quantity messages, switch quantity messages, etc. Device status messages are generated in the order of power supply devices to indicate faults or normal operation. Analog quantity messages simulate the message data when the power supply device is operating normally, such as: voltage values ​​are random values ​​within the range of rated voltage ±5%. Switch quantity messages simulate the opening and closing of contactor switches (e.g., KM1 / KM2).

[0024] Step S130: Send the test messages of each power supply device to the test server to perform simulated testing on the power supply device, that is, the test server performs simulated testing on the power supply device according to the test messages.

[0025] The rail transit power supply equipment testing method of this embodiment reads the power supply equipment configuration file to obtain the configuration information of the power supply equipment in the configuration file, and generates test messages for each power supply equipment based on the power supply equipment type in the configuration information. This realizes the automatic generation of test messages for the power supply equipment. Moreover, after generating the test messages, the method automatically sends the test messages of each power supply equipment to the test server to simulate the test of the power supply equipment. This frees testers from the dilemma of manually generating and sending test messages, shortens the power supply equipment testing cycle, and improves the power supply equipment testing efficiency.

[0026] In some embodiments, step S110, reading the power device configuration file, includes: based on the file path and file name input by the user, reading the power device configuration file corresponding to the file name in the folder corresponding to the file path. This enables the automatic generation of test messages for the user-specified power device.

[0027] Furthermore, the folders are named after the rail transit lines. The number of power supply device configuration files in each folder is equal to the number of stations on the corresponding rail transit line, and each power supply device configuration file is named after its corresponding station. Specifically, each rail transit line corresponds to one folder, which can be named after the corresponding rail transit line. Each folder stores the power supply device configuration files (e.g., in TXT format) for all stations on the corresponding rail transit line. Each power supply device configuration file is named after its corresponding station, meaning each station corresponds to one power supply device configuration file, which contains the configuration information for all power supply devices corresponding to that station. Based on this, testers can easily switch the power message generation for power supply devices on different lines and at different stations by re-specifying the path and name of the power supply device configuration files.

[0028] In some embodiments, after step S110, the method further includes: generating parsing information corresponding to the test message based on the configuration information, and outputting the parsing information to a terminal interface. The parsing information includes: the quantity and serial number of different types of power supply devices, whether each power supply device is alarm-free, the analog value of each power supply device, and the switching value of each power supply device. Outputting the parsing information to the terminal interface is crucial. Without parsing the test message, the message is merely a string of hexadecimal characters, such as AABB123789, making it impossible to identify the device, its corresponding status, or the analog and switching values. Testers would need to manually split and parse the message. Therefore, automatic parsing of test messages helps testers quickly locate the specified power supply device, and the output is more intuitive and clear, improving testing efficiency and accuracy.

[0029] This can be understood as follows: when generating test messages, the corresponding parsing information is presented as comment code in the text of the test message so that testers can view it accordingly.

[0030] In some embodiments, step S120 specifically includes: selecting alarm information, analog quantity information, or switch quantity information corresponding to the control switch from the configuration information of each power supply device according to the preset control switch corresponding to different power supply device types; and generating test messages for each power supply device based on the selected alarm information, analog quantity information, or switch quantity information.

[0031] Understandably, different power supply device types require different test messages. For example, a data acquisition card type power supply device, which does not contain a contactor (KM), only needs to generate alarm messages and analog quantity messages. The script is configured with switch flags for different information such as alarm information, analog quantity information, and digital quantity information. For example, for alarm information, the corresponding switch flag is 1, indicating that an alarm message should be generated based on the alarm information; a flag of 0 indicates that no alarm message should be generated. During script execution, test messages are selectively generated based on the switch flags corresponding to each configuration information, thereby enabling faster coverage of various test scenarios and ensuring the comprehensiveness and timeliness of power supply device testing.

[0032] For example, test scenarios include: Test Scenario 1: Verify the alarm function: The script extracts the configuration information of the power supply device that is triggering the alarm from the configuration information, generates alarm messages such as overvoltage, undervoltage, and overload, and quickly verifies whether the alarm response of the power supply device is accurate.

[0033] Test Scenario 2: Verify parameter monitoring function: The script extracts analog quantities of the power supply equipment's analog components from the rated parameters and configuration information, and generates messages containing real-time voltage, current, and status indicators. The test server can monitor the operating parameters of the power supply equipment through these messages.

[0034] Test Scenario 3: Verify switch quantity function: The script extracts the switch quantities from the configuration information, generates messages containing open and closed states, and quickly verifies whether the status of components such as contactors in the power supply equipment is accurate.

[0035] In some embodiments, step S130, sending the test messages of each power supply device to the test server, includes: sending the test messages of each power supply device to the test server according to preset sending parameters, wherein the sending parameters include at least one of: source IP address, destination IP address (i.e., the IP address of the test server), destination port, sending interval time, or cyclic sending mode. Specifically, the script file can preset the above sending parameters, or it can receive the above sending parameters input by the tester before executing the script.

[0036] The transmission interval represents the time interval between the transmission of adjacent messages, and can be set from 100ms to 10s, with a default value of 1s. For high-frequency tests (such as verifying the dynamic response of the device), this interval can be shortened to 100ms, while for low-frequency stability tests, it can be extended to 10s. Low-frequency transmission, high-frequency transmission, and cyclic transmission all involve the test software monitoring the power supply's response status in real time, thereby verifying the stability of the power supply equipment under long-term operation.

[0037] The following describes the testing apparatus for rail transit power supply equipment provided by the present invention.

Based on the power supply equipment type in the configuration information, it generates test messages for each power supply equipment, thereby realizing the automatic generation of test messages for the power supply equipment. Moreover, after generating the test messages, it automatically sends the test messages of each power supply equipment to the test server to perform simulated testing on the power supply equipment.
