Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of simulation testing of locomotive intelligent driving systems, and in particular to a method and device for dynamically adjusting external resistance testing of locomotive intelligent driving systems. Background Art

[0002] The locomotive running resistance refers to the external resistance generated by the interaction between the locomotive and the external environment, which is opposite to the locomotive operation and hinders the locomotive operation. It is generally divided into the basic locomotive running resistance and the additional locomotive running resistance. The basic locomotive running resistance refers to the resistance generated when running on a flat slope or straight section. The main reasons for the generation include the internal mechanical friction of the locomotive, the friction between the wheels and the rails, and the air resistance. The additional locomotive running resistance refers to the resistance generated when the locomotive runs on a slope, curve, or tunnel section. The additional locomotive running resistance has a very adverse effect on the smooth control and safe control of the locomotive intelligent driving, especially for heavy-loaded 10,000-ton freight locomotives. In the simulation test, the total locomotive resistance F is calculated according to the locomotive resistance simulation model. 总阻力 The formula is as follows: 总阻力 =∑F 基本阻力 +∑F 附加阻力 , where F 基本阻力 It is the basic resistance of the actual locomotive operation. 附加阻力 It is to calculate the various additional resistances of locomotive operation. The calculated locomotive resistance simulation model outputs the total locomotive resistance value for use by the locomotive operation simulation software.

[0003] During the actual operation of heavy-load freight locomotives, the external environment has different impacts, some of which have a great impact on the normal operation of heavy-load freight locomotives. For example, when the locomotive is subjected to high-speed crosswinds at the curves of the line or tailwinds on long downhill slopes, each locomotive will be subjected to an additional force F. i , the force on the whole locomotive is ∑F i This will cause a deviation between the resistance value calculated by the locomotive resistance model and the actual locomotive resistance encountered during locomotive operation, which will have an adverse effect on the smooth operation of the locomotive and even safe driving.

[0004] When the deviation value ΔF is relatively large and consistent with the running direction of the locomotive, the originally stable running state of the heavy-loaded freight locomotive in running scenarios such as downhill or steep downhill will be destroyed, causing the heavy-loaded freight locomotive to accelerate. At this time, whether it is manual driving or intelligent driving, it is necessary to suppress the speed increase by reducing the locomotive traction or increasing the electric braking force. Similarly, when the deviation value ΔF is relatively large and deviates from the running direction of the locomotive, the running of the heavy-loaded freight locomotive in running scenarios such as uphill or steep uphill will also cause the locomotive speed to fail to reach the expected value, and it is also necessary to increase the traction force to prevent the locomotive speed from being too low.

[0005] This random external resistance causes a large deviation between the resistance value calculated by the locomotive resistance simulation model in the laboratory environment and the actual resistance value on site. As a result, the laboratory simulation test cannot effectively verify the intelligent driving system software for the occasional external resistance that affects the traction stability and control safety of heavy-load freight locomotives, posing a hidden danger to field applications.

[0025] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present invention and to enable the scope of the present invention to be fully communicated to those skilled in the art.

[0026] Figure 1 The flowchart of the method for dynamically adjusting the external resistance test of the locomotive intelligent driving system provided by the embodiment of the present invention is shown. Figure 1 As shown, the method for dynamically adjusting the external resistance test of the locomotive intelligent driving system is applied to the locomotive intelligent driving system, including:

[0027] Step S11: determine a test circuit and a test scenario, and select a resistance model calibration library corresponding to the test circuit and the test scenario.

[0028] The test scenarios include: starting scenario, parking scenario, circulating air brake, safety protection, and interval operation control scenario. Before step S11, a resistance model calibration library is built for the actual line mode / custom mode according to the test scenario. When the custom mode is used, the entire line is treated as a whole and the same calibration value ΔF is set for the entire line. i , 4 types of resistance model calibration libraries can be generated. When the actual route method is adopted, the corresponding ΔF is set for the locations with relatively large actual deviations in the entire road section according to the actual route data analysis. i value, forming a resistance model calibration library close to the actual operating environment; different ΔF values ​​can also be set for the line slope greater than or equal to ± 4 thousandths, the curve radius less than 800, the bridge and tunnel sections in the offline data according to the test requirements. i values ​​to form a resistance model calibration library of different combinations for the entire line.

[0029] In an embodiment of the present invention, for any test scenario of any test route, field test data of external resistance of different locomotives with different freight load configurations are obtained; the maximum difference between the actual resistance and the expected resistance of any position to be tested on the test route is determined based on the field test data; a resistance calibration set at the position to be tested is determined based on the maximum difference; and the resistance calibration sets at all the positions to be tested under the test route and the test scenario are collected to obtain a resistance model calibration library corresponding to the test route and the test scenario. The resistance model calibration library ΔFi includes four types of calibration values: ΔF i ∈{F 弱i |F 强i |F 特别强i |F 普通i}, where i is an integer from 1 to n, and n is the number of locations in the test scenario that meet the specific test line requirements that affect the smooth operation of the locomotive. 弱i As a general simulation field environment stability function test method; F 普通i 、F 强i As a powerful stability test method for the intelligent driving system of the circulating air brake section locomotive; 特别强i Test the stability and control limits of locomotive intelligent driving system.

[0030] In an embodiment of the present invention, for any position to be tested on the test line, the difference between the actual resistance output by the central control unit (CCU) device on the locomotive at each same moment and the expected resistance calculated by the locomotive intelligent driving system software installed on the locomotive is taken; the maximum difference is selected from the differences obtained at each moment of any position to be tested on the test line. After obtaining the maximum difference, classification is performed according to the proportion based on the maximum difference, wherein the first proportion of the maximum difference is used as the normal calibration value, the second proportion of the maximum difference is used as the weak calibration value, the third proportion of the maximum difference is used as the strong calibration value, and the fourth proportion and above of the maximum difference are used as the particularly strong calibration values, the first proportion, the second proportion, the third proportion and the fourth proportion increase in sequence, preferably, they are 10%, 20%, 50% and 100% respectively, and the maximum value range of the normal calibration value, the weak calibration value, the strong calibration value and the particularly strong calibration value is [-500,500]; the normal calibration value, the weak calibration value, the strong calibration value and the particularly strong calibration value are combined to form the resistance calibration set at the position to be measured.

[0031] In step S11, a corresponding resistance model calibration library is selected according to the determined test line and test scenario. The resistance model calibration library includes a resistance calibration set at each position to be tested of the test line under the test scenario.

[0032] Step S12: determining a combination sequence of calibration values ​​at each to-be-tested position of the test circuit according to the test circuit and the resistance model calibration library.

[0033] In step S12, a resistance calibration set at each position to be tested of the test line is determined according to the resistance model library; a calibration value is selected from the resistance calibration set at each position to be tested according to the test line and the test scenario to form a combination sequence of calibration values. If there are n positions to be tested that affect the stability of the locomotive on the test line, it means that there are 4 nThe test process usually selects a calibration library of typical combinations, such as selecting the same type for a calibration library, or selecting a combination of two or more types. For example, if a general simulation field environment stability function test is performed on a locomotive at all test locations, F can be selected at each test location on the test line. 弱i Or if the locomotive is to be tested for strong stability at some of the locations to be tested, F can be selected at some of the locations to be tested on the test line. 普通i As the calibration value, select F at some of the positions to be measured. 强i as calibration value.

[0034] Step S13: At each position to be tested on the test line, the output value of the locomotive resistance simulation model is adjusted according to the combination sequence to complete the external resistance test of the test line in the test scenario.

[0035] In the embodiment of the present invention, optionally, when the locomotive reaches any position to be tested along the test line, a calibration value corresponding to the position to be tested is selected from the combination sequence; the locomotive resistance simulation model is used to calculate the total resistance of the locomotive; the locomotive simulation is performed using the sum of the calibration value and the total resistance as the calibrated locomotive total resistance, thereby completing the external resistance test of the test line in the test scenario. Figure 2 As shown, the locomotive resistance simulation model calculates the locomotive resistance F 总阻力 Finally, use the calibration value ΔF in the resistance model calibration library i With F 总阻力 Perform arithmetic addition and subtraction to obtain the calibrated total locomotive resistance F' 总阻力 Passed to the locomotive operation simulation software.

[0036] F' 总阻力 =F 总阻力 +ΔF i

[0037] In an embodiment of the present invention, the locomotive intelligent driving system external resistance testing system is as follows: Figure 3 As shown, it includes locomotive simulation software, driver console simulation software, test equipment, and units under test. The locomotive simulation software is based on the calibrated locomotive total resistance F' 总阻力Output traction / electric braking force to the driver console simulation software, and output working conditions, level, force information, etc. to the units under test including the intelligent driving control unit and the human-machine interaction unit through the driver console simulation software. The test equipment obtains the test information of the units under test and conducts locomotive simulation testing. The locomotive simulation software and the driver console simulation software transmit Ethernet interaction information to each other with the test equipment including LKJ portable equipment, CCU equipment and network equipment. The test equipment and the units under test can transmit Ethernet and Multifunction Vehicle Bus (MVB) interaction information to each other.

[0038] In the embodiment of the present invention, when the requirements of the test scenario and calibration library are determined, such as a strong combination, the calibration value of the resistance model is set according to the requirements. When the simulation test runs to the i-th position to be tested, the i-th calibration value in the combination sequence of the current resistance model calibration library is applied to adjust the output value of the locomotive resistance simulation model. Repeat this step until the combination sequence of all resistance model calibrations of the test scenario selected in this round of test is completed. Then stop the simulation test and download the test data. This is a complete test process.

[0039] The method for dynamically adjusting the external resistance test of the locomotive intelligent driving system in the embodiment of the present invention constructs a resistance model calibration library and applies the combined sequence in the resistance calibration library in the test, so that the total train resistance output after the resistance calibration is injected in the simulation test is close to the actual effect on site. On this basis, a robustness test for train smooth control under extreme environments can be constructed, so that the locomotive intelligent driving system can better verify the locomotive intelligent driving control ability, enrich the test scenarios of the locomotive intelligent driving system, and more comprehensively test the locomotive intelligent driving system.

[0040] To summarize, the method for dynamically adjusting the external resistance test of a locomotive intelligent driving system in an embodiment of the present invention determines a test circuit and a test scenario, and selects a resistance model calibration library corresponding to the test circuit and the test scenario; determines a combination sequence of calibration values ​​at each position to be tested on the test circuit according to the test circuit and the resistance model calibration library; at each position to be tested on the test circuit, adjusts the output value of the locomotive resistance simulation model according to the combination sequence to complete the external resistance test of the test circuit under the test scenario, which can make the total train resistance output after the resistance calibration is injected into the simulation test close to the actual effect on site, can better verify the locomotive intelligent driving control capability, and facilitate a more comprehensive inspection of the locomotive intelligent driving system.
