The entire process, including before, during, and after the test, requires a significant investment of manpower and resources.

[0019] And / or, a vehicle-end speed sensor, connected to the server, is used to collect the vehicle-end speed parameters of the test vehicle while it is in motion, and send the vehicle-end speed parameters to the server.

[0020] Specifically, this embodiment provides an implementation method for a vehicle-side data module. By setting up multiple sensors on the test vehicle, it enables the acquisition of various test data when the test vehicle is tested on the driving route, and transmits the test data to the server for management and analysis.

By setting up multiple sensors on the ground-based equipment, it enables the acquisition of various test data of the test vehicle and the ground-based equipment when the test vehicle enters the corresponding area of ​​the ground-based equipment, and transmits the test data to the server for management and analysis.

[0030] According to one embodiment of the present invention, it further includes: a display terminal, the display terminal being connected to the server to display test data of the test vehicle and the ground terminal equipment.

[0031] Specifically, this embodiment provides an implementation method for a display terminal. By setting up a display terminal, information related to the shared database built by the server can be displayed, making it easier to observe the progress of the unmanned rail vehicle in the test more intuitively.

[0032] According to a second aspect of the present invention, a test method for an intelligent test system based on the above-described unmanned rail vehicle includes:

[0033] Obtain the vehicle-end test parameters of the test vehicle on the driving route, wherein there are at least two test vehicles on the driving route;

[0034] Obtain the ground test parameters when the test vehicle passes the ground terminal equipment;

[0035] A simultaneous domain shared database is constructed based on the vehicle-side test parameters and the ground-side test parameters.

[0036] According to one embodiment of the present invention, the step of obtaining the vehicle-end test parameters of the test vehicle on the driving route specifically includes:

[0037] One of the test vehicles is designated as the original vehicle, and the original vehicle is tested with a first preset operating parameter, wherein the first preset operating parameter is the parameter for the original vehicle to run with the preset operating data of the server;

[0038] After the original vehicle drives through the collection area, the original test parameters of the original vehicle are collected and judged.

[0039] If the original test parameters of the vehicle end are determined to meet the preset vehicle end threshold, then the original test parameters of the vehicle end are sent to the other test vehicles and the server.

[0040] Specifically, this embodiment provides an implementation method for obtaining vehicle-end test parameters of a test vehicle on a driving route. By marking a test vehicle as the original vehicle, the original vehicle is allowed to conduct a trial run first according to the first preset operating parameters. By calculating and analyzing the data from the trial run, data support is provided for the operation tests of other test vehicles, and the problem of other test vehicles needing to repeatedly test the same set of data is avoided.

[0041] According to one embodiment of the present invention, the step of collecting and judging the original test parameters of the original vehicle after it has passed through the collection area further includes:

[0042] If it is determined that the original test parameters of the vehicle end do not meet the preset vehicle end threshold, then the original parameter list of the vehicle end is extracted, and a judgment is made based on the original parameter list of the vehicle end.

[0043] Determine the vehicle-end original first parameter and the vehicle-end original second parameter in the vehicle-end original parameter list, wherein the vehicle-end original first parameter is a parameter that meets the preset vehicle-end threshold, and the vehicle-end original second parameter is a parameter that does not meet the preset vehicle-end threshold;

[0044] The original first parameters of the vehicle terminal are sent to the other test vehicles. The second preset operating parameters are generated based on the original first parameters of the vehicle terminal and the preset iterative operating parameters. The other test vehicles perform operating tests based on the second preset operating parameters.

A third preset operating parameter is generated based on the offset. The original vehicle performs iterative operation tests with the third preset operating parameter until the original test parameter of the vehicle meets the preset vehicle threshold.

[0046] Specifically, this embodiment provides an implementation method for collecting and judging the original vehicle-side test parameters. When the collected original vehicle-side test parameters do not meet the preset vehicle-side threshold, the original vehicle-side parameter list is obtained, and the parameters that meet the preset vehicle-side threshold are directly sent to the other test vehicles so that the other test vehicles can perform corresponding tests based on the parameters that meet the preset vehicle-side threshold. For parameters that do not meet the preset vehicle-side threshold, the offset is extracted, and the parameters that do not meet the threshold are corrected based on the offset until all the corresponding data collected by the original vehicle meet the preset vehicle-side threshold.

[0048] A fourth preset operating parameter is generated based on the original test parameters of the vehicle and the preset iterative operating parameters, and the remaining test vehicles conduct operating tests based on the fourth preset operating parameter.

[0049] After the remaining test vehicles drive through the collection area, the vehicle-side iterative test parameters of the test vehicles are collected and judged.

[0050] If the vehicle-side iterative test parameters are determined to meet the preset vehicle-side threshold, then the vehicle-side iterative test parameters are sent to the server.

[0051] Specifically, this embodiment provides an implementation method in which the original test parameters of the vehicle end are sent to the other test vehicles and the server. The other test vehicles generate a fourth preset operating parameter based on the original test parameters of the vehicle end and the preset iterative operating parameters to conduct tests in the corresponding scenarios, so as to realize the test of unmanned rail vehicles and support the construction of a simultaneous domain big data.

[0052] According to one embodiment of the present invention, the step of collecting and judging the iterative test parameters of the test vehicles after the remaining test vehicles have passed the collection area specifically includes:

[0053] If it is determined that the vehicle-end iterative test parameters do not meet the preset vehicle-end threshold, then the vehicle-end iterative parameter list is extracted, and a judgment is made based on the vehicle-end iterative parameter list;

[0054] Determine the first vehicle-end iteration parameter and the second vehicle-end iteration parameter in the vehicle-end iteration parameter list, wherein the first vehicle-end iteration parameter is a parameter that does not meet the preset vehicle-end threshold, and the second vehicle-end iteration parameter is a parameter that meets the preset vehicle-end threshold;

[0055] The offset between the first iterative parameter of the vehicle end and the corresponding preset vehicle end threshold is extracted. A fifth preset operating parameter is generated based on the offset. The remaining test vehicles perform iterative operation tests with the fifth preset operating parameter until the iterative test parameters of the vehicle end meet the preset vehicle end threshold.

[0056] Specifically, this embodiment provides an implementation method for collecting and judging the iterative test parameters of the test vehicle. If it is determined that the iterative test parameters of the other test vehicles do not meet the preset vehicle threshold, the corresponding iterative parameter list is obtained, the offset of the parameters that do not meet the preset vehicle threshold is extracted, and the parameters that do not meet the preset vehicle threshold are corrected according to the offset, so that the corresponding data collected by the test vehicles all meet the preset vehicle threshold.

[0057] According to one embodiment of the present invention, the step of obtaining the ground test parameters when the test vehicle passes the ground terminal equipment specifically includes:

[0058] The test vehicle passes through the ground terminal equipment and obtains the ground terminal first parameter, ground terminal second parameter, and ground terminal third parameter, wherein the ground terminal first parameter is the parameter corresponding to the test vehicle, the ground terminal second parameter is the parameter corresponding to the ground terminal equipment, and the ground terminal third parameter is the environmental parameter corresponding to the test vehicle passing through the ground terminal equipment.

[0059] The ground test parameters are generated based on the first ground parameter, the second ground parameter, and the third ground parameter.

[0060] Specifically, this embodiment provides an implementation method for obtaining ground-end test parameters when the test vehicle passes the ground-end equipment. By obtaining the ground-end test parameters, the server can construct a simultaneous domain test database that is integrated throughout the entire process and consistent in time and space based on the vehicle-end test parameters and the ground-end test parameters. This satisfies the data sharing and scenario testing requirements among multiple unmanned test vehicles and multiple ground-end equipment, improves the intelligence level of modern unmanned rail vehicle testing, increases test efficiency, shortens the test cycle, reduces labor costs, and accelerates the promotion and application of new technologies.

The other test vehicles conduct tunnel tests according to the corresponding vehicle-side original test parameters. It should be noted that the other test vehicles and the original vehicle can be the same type of vehicle to test the difference data, or they can be different types of vehicles to test the difference vehicles. The different vehicles can be vehicle type, speed, number of trains, weight, load, power supply type, driving mode, etc.

[0130] In one application scenario, the test vehicle is used to test a turnout. The original vehicle operates according to the first preset operating parameters. After the original vehicle passes the corresponding turnout, the corresponding original test parameters of the original vehicle are collected and analyzed. The original test parameters that meet the test requirements are sent to the other test vehicles. The other test vehicles then perform turnout tests based on the corresponding original test parameters. It should be noted that the other test vehicles and the original vehicle can be the same type of vehicle to test the difference data, or they can be different types of vehicles to test the difference vehicles. The different vehicles can be of different types, speeds, train formations, weights, loads, power supply types, driving modes, etc.

[0131] In one application scenario, the test vehicle is tested at a station. The original vehicle operates according to the first preset operating parameters. After the original vehicle passes through or stops at the corresponding station, the corresponding original test parameters of the original vehicle are collected and analyzed. The original test parameters that meet the test requirements are sent to the other test vehicles. The other test vehicles conduct station tests according to the corresponding original test parameters. It should be noted that the other test vehicles and the original vehicle can be the same type of vehicle to test the difference data, or they can be different types of vehicles to test the difference vehicles. The different vehicles can be vehicle type, speed, number of trains, weight, load, power supply type, driving mode, etc.

[0132] In one application scenario, the test vehicle is tested on a curve. The original vehicle operates according to the first preset operating parameters. After the original vehicle passes the corresponding curve, the corresponding vehicle-side original test parameters are collected and analyzed. The vehicle-side original test parameters that meet the test requirements are sent to the other test vehicles. The other test vehicles then conduct curve tests based on the corresponding vehicle-side original test parameters. It should be noted that the other test vehicles and the original vehicle can be the same type of vehicle to test different data, or they can be different types of vehicles to test different vehicles. Different vehicles can be of different types, speeds, number of trains, weights, loads, power supply types, driving modes, etc.

[0133] In some possible embodiments of the present invention, the step of collecting and judging the original test parameters of the original vehicle after it has driven through the collection area specifically includes:

[0134] If it is determined that the original test parameters of the vehicle end do not meet the preset vehicle end threshold, then the list of original vehicle end parameters is extracted, and a judgment is made based on the list of original vehicle end parameters;

[0135] Determine the vehicle-side original first parameter and vehicle-side original second parameter in the vehicle-side original parameter list, wherein the vehicle-side original first parameter is the parameter that meets the preset vehicle-side threshold, and the vehicle-side original second parameter is the parameter that does not meet the preset vehicle-side threshold;

[0136] The original first parameters from the vehicle are sent to the other test vehicles. The second preset operating parameters are generated based on the original first parameters from the vehicle and the preset iterative operating parameters. The other test vehicles then conduct operating tests based on the second preset operating parameters.

[0137] Extract the offset between the original second parameter of the vehicle and the corresponding preset vehicle threshold, generate the third preset operating parameter based on the offset, and perform iterative operation test on the original vehicle with the third preset operating parameter until the original test parameter of the vehicle meets the preset vehicle threshold.

[0138] Specifically, this embodiment provides an implementation method for collecting and judging the original test parameters of the original vehicle. When the collected original test parameters do not meet the preset vehicle threshold, the original parameter list is obtained, and the parameters that meet the preset vehicle threshold are directly sent to the other test vehicles so that the other test vehicles can perform corresponding tests based on the parameters that meet the preset vehicle threshold. For the parameters that do not meet the preset vehicle threshold, the offset is extracted, and the parameters that do not meet the threshold are corrected based on the offset until all the corresponding data collected by the original vehicle meet the preset vehicle threshold.

[0139] In one application scenario, when the original vehicle is driving through a tunnel, the vehicle-end noise parameter collected in the original test parameters does not meet the preset vehicle-end threshold. The server 30 extracts the offset between the vehicle-end noise parameter and the preset vehicle-end threshold based on the corresponding calculations and analysis to determine the cause of the problem, such as adjusting the tunnel entry speed or using a constant speed to pass through the tunnel. Based on the offset, a third preset operating parameter is generated so that the original vehicle can be tested in the tunnel again until all the collected original test parameters meet the preset vehicle-end threshold.

[0140] In one application scenario, when the original vehicle passes through a turnout, the vibration parameters at the vehicle end of the original test parameters collected do not meet the preset vehicle end threshold. The server 30 extracts the offset between the vibration parameters at the vehicle end and the preset vehicle end threshold based on the corresponding calculations and analysis to determine the cause of the problem, such as adjusting the speed of entering the turnout or using deceleration to pass through the turnout. Based on the offset, a third preset operating parameter is generated so that the original vehicle can perform the turnout test again until all the original test parameters collected at the vehicle end meet the preset vehicle end threshold.

[0141] In one application scenario, when the original vehicle passes through or stops at a station, the vehicle-end command parameters collected in the original test parameters do not meet the preset vehicle-end threshold. The server 30 extracts the offset between the vehicle-end command parameters and the preset vehicle-end threshold based on the corresponding calculations and analysis to determine the cause of the problem, such as the time node when the vehicle-end command was issued, the action sequence corresponding to the vehicle-end command, etc., and generates a third preset operating parameter based on the offset, so that the original vehicle can perform station testing again until all the collected original test parameters meet the preset vehicle-end threshold.

[0142] In one application scenario, when the original vehicle is driving through a curve, the vehicle speed parameter collected from the original test parameters does not meet the preset vehicle threshold. The server 30 extracts the offset between the vehicle speed parameter and the preset vehicle threshold based on the corresponding calculations and analysis to determine the cause of the problem, such as the initial speed of the test vehicle when entering the curve and the acceleration of the test vehicle when cornering. Based on the offset, a third preset operating parameter is generated so that the original vehicle can perform the curve test again until all the collected original test parameters meet the preset vehicle threshold.

[0143] In some possible embodiments of the present invention, after the step of sending the original test parameters from the vehicle to the other test vehicles and server 30, the specific steps include:

[0144] The fourth preset operating parameters are generated based on the original test parameters and preset iterative operating parameters at the vehicle end, and the remaining test vehicles conduct operating tests based on the fourth preset operating parameters.

[0145] After the remaining test vehicles have passed the data collection area, the iterative test parameters at the vehicle end of the test vehicles are collected and judged.

[0146] If the vehicle-side iterative test parameters are determined to meet the preset vehicle-side threshold, then the vehicle-side iterative test parameters are sent to server 30.

[0147] Specifically, this embodiment provides an implementation method in which the original test parameters of the vehicle are sent to the other test vehicles and the server 30. The other test vehicles generate a fourth preset operating parameter based on the original test parameters of the vehicle and the preset iterative operating parameters to conduct tests in the corresponding scenarios, so as to realize the test of unmanned rail vehicles and support the construction of a large database in the same domain.

[0148] In some possible embodiments of the present invention, the step of collecting and judging the iterative test parameters at the vehicle end of the test vehicles after the other test vehicles have passed the collection area specifically includes:

[0149] If it is determined that the vehicle-side iterative test parameters do not meet the preset vehicle-side threshold, then the vehicle-side iterative parameter list is extracted, and a judgment is made based on the vehicle-side iterative parameter list;

[0150] Determine the first vehicle-end iteration parameter and the second vehicle-end iteration parameter in the vehicle-end iteration parameter list, wherein the first vehicle-end iteration parameter is the parameter that does not meet the preset vehicle-end threshold, and the second vehicle-end iteration parameter is the parameter that meets the preset vehicle-end threshold;

[0151] Extract the offset between the first parameter of the vehicle-end iteration and the corresponding preset vehicle-end threshold. Generate the fifth preset operating parameter based on the offset. The remaining test vehicles perform iterative operation tests with the fifth preset operating parameter until the vehicle-end iterative test parameters meet the preset vehicle-end threshold.

[0152] Specifically, this embodiment provides an implementation method for collecting and judging the iterative test parameters of the test vehicle. If it is determined that the iterative test parameters of the other test vehicles do not meet the preset vehicle threshold, the corresponding iterative parameter list is obtained, the offset of the parameters that do not meet the preset vehicle threshold is extracted, and the parameters that do not meet the preset vehicle threshold are corrected according to the offset, so that the corresponding data collected by the test vehicle all meet the preset vehicle threshold.

[0153] In some possible embodiments of the present invention, the step of obtaining the ground test parameters when the test vehicle passes the ground terminal equipment specifically includes:

[0154] The test vehicle obtains the first ground parameter, the second ground parameter, and the third ground parameter when it passes the ground equipment. The first ground parameter is the parameter of the corresponding test vehicle, the second ground parameter is the parameter of the corresponding ground equipment, and the third ground parameter is the environmental parameter of the corresponding test vehicle when it passes the ground equipment.

[0155] The ground test parameters are generated based on the first ground parameter, the second ground parameter, and the third ground parameter.

[0156] Specifically, this embodiment provides an implementation method for obtaining ground-end test parameters when a test vehicle passes over ground-end equipment. By obtaining the ground-end test parameters, the server 30 can construct a simultaneous domain test database that integrates the entire process of test data and is consistent in time and space based on the vehicle-end test parameters and the ground-end test parameters. This satisfies the data sharing and scenario testing requirements among multiple unmanned test vehicles and multiple ground-end equipment, improves the intelligence level of modern unmanned rail vehicle testing, increases test efficiency, shortens the test cycle, reduces labor costs, and accelerates the promotion and application of new technologies.

[0157] In a possible implementation, server 30 also includes functions such as organizational structure management, user management, role management, permission management, and basic dimension table management, assisting system administrators in daily system maintenance and operation, and supporting flexible system management functions. An intelligent test management main interface is set up; upon first login, the user enters the main interface. The main interface mainly includes management menus, vehicle and test track status, etc. The management menu includes vehicle type management, signal system model management, and test scenario management. Vehicle and test track status includes vehicle grouping, test track map, and real-time vehicle location on the test track.

[0158] In a possible implementation, server 30 can establish complete test scenarios and test databases for different vehicle models and systems, supporting the creation of new test scenarios and test data management lists, as well as functions such as querying, classifying, and comparing historical test data. It can also interpret, analyze, modify, and save test cases, completing the process decomposition from test cases to test execution.

[0159] In a possible implementation, the server 30 can configure a management interface for different scenario tests. It is the control interface for scenario tests, which can set test start commands, configure simulated signals during the test process, set test indicators for performance evaluation, and send test commands and other configuration data to the test command execution unit.

[0160] In a possible implementation, after entering the scenario test, the status screen of the test process is displayed in real time, including the real-time status of the vehicle and the track, the dynamic status of the field equipment, and test data. The vehicle status includes vehicle grouping, main control, direction, driving mode, pantograph lifting status, vehicle speed, traction and braking status, distance between vehicles, real-time position of the vehicle on the track, and door opening and closing status after parking.

[0161] In a possible implementation, performance data is collected synchronously with the scenario test and analyzed by software based on the corresponding performance data calculation model. Performance data is displayed in the form of charts, curves, etc. After all scenarios are completed, the system automatically evaluates whether each performance parameter is acceptable.

[0162] In a possible implementation, an automatic test report generation function is set up to realize test data statistics and analysis. Based on the selected test report items, the system automatically retrieves test data charts, curves and evaluation results, and generates corresponding functional and performance test reports, as well as functional and performance comparison reports for different vehicle models or different systems.
