DETAILED DESCRIPTION

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the present invention.

[0024] To facilitate understanding of this embodiment, the following is a brief introduction to the technical terms used in this application.

[0025] After introducing the technical terms involved in this application, the application scenarios and design concepts of the embodiments of this application are briefly introduced.

[0026] At present, during the rail transit vehicle testing process, the rail transit vehicle to be tested needs to be moved, which is inconvenient to operate and difficult to move, resulting in low testing efficiency.

[0027] Based on this, the embodiments of the present application provide a test system for thermal management of rail transit vehicles and a control method and device thereof.

[0028] Example 1 This application provides a test system for thermal management of rail transit vehicles, combined with Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, the test system includes: a main frame 1, a guide rail assembly 2, a solar radiation system array 3, a relative position adjustment assembly 4, a cable assembly 5 and a control unit 6.

[0029] The main frame 1 is arranged below the guide rail assembly 2 and is fixed to the load-bearing structure on the top of the experimental cabin through the guide rail assembly 2; the main frame 1 can move in a first direction relative to the guide rail assembly 2.

[0030] A traction terminal 21 is provided at one end of the guide rail assembly 2 ; a rail transit vehicle to be tested is mounted on the guide rail assembly 2 .

[0031] The solar radiation system array 3 is symmetrically arranged below the guide rail assembly 2 along the second direction and located on the inner side of the main frame 1.

[0032] The relative position adjustment component 4 is used to adjust the relative position between the rail transit vehicle to be tested and the solar radiation system array 3 .

[0033] The cable assembly 5 is arranged inside the guide rail assembly 2. One end of the cable in the cable assembly 5 is detachably connected to the rail transit vehicle to be tested, and the other end is connected to the testing device.

[0034] The control unit 6 is in communication connection with the solar radiation system array 3 , the relative position adjustment component 4 and the testing device.

[0035] The first direction and the second direction are in the same plane and perpendicular to each other.

[0036] In this embodiment, the rail transit vehicle to be tested is placed on the guide rail assembly 2. Under the adjustment action of the relative position adjustment assembly 4, the position and angle of the solar radiation system array 3 in the first direction are changed to adjust the relative position between the solar radiation system array 3 and the rail transit vehicle to be tested on the guide rail assembly 2. Then, the performance test is carried out under the action of the solar radiation system array 3. Compared with the existing technology, the difficulty of moving the rail transit vehicle to be tested can be reduced by moving the solar radiation system array 3 instead of the existing method of moving the rail transit vehicle to be tested, thereby reducing the positioning difficulty and improving the detection efficiency and accuracy.

[0037] Please refer to Figure 1 As shown, Figure 1This is a top view of the test system for rail transit vehicle thermal management provided in this application. A solar radiation system array 3 is disposed inside the main frame 1 and below the guide rail assembly 2, with the first direction being direction A and the second direction being direction B. It is understood that the main frame 1 is slidably connected below the guide rail assembly 2. As one possible implementation, a slide rail is provided at the bottom of the guide rail assembly 2, which slidably engages with a slider connected to the main frame 1. This is merely an example; it is understood that movement can also be achieved through pulley transmission, rack and pinion transmission, or magnetic levitation lamps, and is not limited here. In this embodiment, the solar radiation system array 3 is rotatably connected to the inside of the main frame 1. The solar radiation system array 3 is rotated to adjust the angle of light. It is understood that this rotational connection can be implemented in a variety of ways, such as using a gear transmission mechanism with a slewing bearing. The slewing bearing (also known as a rotary bearing) is a special bearing device that can withstand large loads while allowing the structure to rotate smoothly. It is often a key component connecting the fixed structure to the movable component. In this way, the entire solar radiation system array 3 can be flexibly rotated around an axis, thereby adjusting the angle of the light emitted by the solar radiation system array 3.

[0038] In combination with the first aspect, the relative position adjustment component 4 includes: a parallel traction component 41, which is used to adjust the relative distance between the rail transit vehicle to be tested and the solar radiation system array 3 in a first direction.

[0039] In combination with the first aspect, the parallel traction assembly 41 includes: a parallel traction motor 411 and a parallel wire rope drum 412 .

[0040] The parallel traction motor 411 is fixed to the main frame 1 inside the guide rail assembly 2 .

[0041] The parallel wire rope drum 412 is provided in the guide rail assembly 2 . A wire rope is wound around the parallel wire rope drum 412 . The free end of the wire rope is fixedly connected to the traction terminal 21 .

[0042] The parallel traction motor 411 is energized to rotate and pull the main frame 1 and the solar radiation system array 3 along the first direction through the wire rope to adjust the relative distance between the rail transit vehicle to be tested and the solar radiation system array 3.

[0043] Please refer to Figure 2 , Figure 2 This is a side view of the test system for thermal management of rail transit vehicles provided in this application. In this application, the relative position adjustment component 4 includes a parallel traction component 41 for adjusting the relative distance between the rail transit vehicle to be tested and the solar radiation system array 3 in a first direction. Specifically, in combination with Figure 3The parallel traction assembly 41 shown includes a parallel traction motor 411 and a parallel wire rope drum 412, wherein the free end of the wire rope wound on the parallel wire rope drum 412 is fixedly connected to the traction terminal 21. Under the action of the parallel traction motor 411, the output end of the parallel traction motor 411 is connected to the parallel wire rope drum 412 to drive the parallel wire rope drum 412 to rotate, thereby reeling in or releasing the wire rope, and then pulling the main frame 1 fixed with the solar radiation system array 3 to move in a first direction to move closer to or away from the traction terminal 21. In this way, the position of the main frame 1 is adjusted in the first direction, and the position of the solar radiation system array 3 fixed to the inner side of the main frame 1 is adjusted in the first direction, thereby adjusting the relative position of the solar radiation system array 3 and the rail transit vehicle to be tested fixed on the guide rail assembly 2 in the first direction.

[0044] In combination with the first aspect, the relative position adjustment component 4 further includes: a tilting traction component 42 .

[0045] The tilting traction assembly 42 is used to adjust the relative angle between the rail transit vehicle to be tested and the solar radiation system array 3 .

[0046] In combination with the first aspect, the inclined traction assembly 42 includes: an inclined traction motor 421 and an inclined wire rope drum 422 .

[0047] The tilt traction motor 421 is fixed below the guide rail assembly.

[0048] The inclined wire rope drum 422 is disposed in the guide rail assembly 2 . A wire rope is wound around the inclined wire rope drum 422 . The free end of the wire rope is fixedly connected to the solar radiation system array 3 .

[0049] The tilt traction motor 421 is powered and rotates to pull the solar radiation system array 3 through the steel wire rope to rotate, so as to adjust the relative angle between the solar radiation system array 3 and the rail transit vehicle to be tested on the guide rail assembly 2.

[0050] Please refer to Figure 2 As shown, the output end of the tilting traction motor 421 is connected to the tilting wire rope drum 422 to drive the tilting wire rope drum 422 to rotate forward or reverse, thereby reeling in or releasing the wire rope, and the end of the wire rope is connected to the solar radiation system array 3, so that under the action of the tilting traction motor 421, the angle of the solar radiation system array 3 relative to the rail transit vehicle to be tested can be adjusted.

[0051] In this way, for rail transit vehicles of different sizes and models to be tested, the position and angle of the first direction of the solar radiation system array 3 can be adjusted to a suitable test position, which can adapt to different test requirements and is conducive to improving the generalization, effectiveness and adaptability of the test system.

[0052] In combination with the first aspect, the cable assembly 5 includes: a cable and a cable management structure for wrapping one or more cables.

[0053] The test cables or cables required for communication are wrapped and packaged through the cable management structure to simplify the external structure and reduce the impact of placing complex lines in the test area on the test.

[0054] In a second aspect, the present application provides a control method for a test system for thermal management of a rail transit vehicle, which is applied to a control unit in the test system for thermal management of a rail transit vehicle as described above.

[0055] Combine Figure 4 As shown, in the system, the control unit 6 is connected to the solar radiation system array 3, the relative position adjustment component 4 and the testing device.

[0056] Combine Figure 5 As shown, the method includes: S110, fixing the rail transit vehicle to be tested on the guide rail assembly.

[0057] S120, controlling the relative position adjustment component to operate so as to adjust the position of the solar radiation system array relative to the rail transit vehicle to be tested.

[0058] S130, based on the preset test process, controlling the operation of the solar radiation system array to obtain the test results.

[0059] In the present application, the relative position adjustment component 4 is first controlled to operate to adjust the position and angle of the solar radiation system array 3 in the first direction, thereby adjusting the relative position of the rail transit vehicle to be tested and the solar radiation system array 3, and then the test is performed based on a preset test process. In the present application, the target position of the solar radiation system array 3 required for the test is adjusted to replace the method of adjusting the large rail transit vehicle to be tested in the prior art, which can effectively reduce the difficulty and labor of position adjustment, and through relative position adjustment, different models of rail transit vehicles to be tested can be tested, which is conducive to improving the accuracy and generalization of the test.

[0060] In conjunction with the second aspect, the relative position includes a relative distance.

[0061] Step S120 specifically includes: S121, controlling the operation of the parallel traction motor in the parallel traction assembly, and moving the main support fixed with the solar radiation system array by pulling the steel wire rope in the first direction to adjust the relative distance between the rail transit vehicle to be tested on the guide rail assembly and the solar radiation system array.

[0062] In this embodiment, the control unit 6 is electrically connected to the parallel traction motor 411, and the parallel traction motor 411 is started by the control unit 6 to drive the parallel wire rope drum 412 to rotate, thereby reeling in or releasing the wire rope, thereby adjusting the position of the solar radiation system array 3 in the first direction, and then adjusting the relative distance between the rail transit vehicle to be tested on the guide rail assembly 2 and the solar radiation system array 3.

[0063] In conjunction with the second aspect, the relative position also includes the relative angle.

[0064] Step S120 specifically includes: S122, controlling the tilt traction motor in the tilt traction assembly to rotate the solar radiation system array by pulling the steel wire rope to adjust the relative angle between the solar radiation system array and the rail transit vehicle to be tested on the guide rail assembly.

[0065] In this embodiment, the control unit 6 is electrically connected to the tilt traction motor 421, and the tilt traction motor 421 is started by the control unit 6 to drive the tilt wire rope drum 422 to rotate, thereby reeling in or releasing the wire rope, thereby adjusting the spatial position of the solar radiation system array 3, and further adjusting the relative angle between the rail transit vehicle to be tested on the guide rail assembly 2 and the solar radiation system array 3.

[0066] It can be understood that in step S120, the solar radiation system array 3 can be adjusted from two dimensions, namely, the first direction position and the spatial angle, so as to adjust the relative position of the solar radiation system array 3 and the rail transit vehicle to be tested. In actual application, not every adjustment needs to be made from two dimensions. For example, the model and size of the rail transit vehicle to be tested this time are exactly the same as those of the rail transit vehicle tested last time. At this time, the last test angle can be used, and the position can be adjusted only from the first direction. Similarly, if the models and sizes of the rail transit vehicles tested twice are different, but the positions installed on the guide rail assembly 2 are exactly the same, only the spatial angle of the solar radiation system array 3 can be adjusted. The above is only an example and is not limited here.

[0067] In a third aspect, the present application provides a control device for a test system for thermal management of a rail transit vehicle, which is applied to a control unit in the test system for thermal management of a rail transit vehicle as described above.

[0069] The adjustment module 20 is used to control the operation of the relative position adjustment component to adjust the position of the solar radiation system array relative to the rail transit vehicle to be tested.

[0070] The test module 30 is used to control the operation of the solar radiation system array based on a preset test process and obtain test results.

[0071] In a fifth aspect, the present application provides an electronic device, Figure 7 As shown, the electronic device includes a memory 131 and a processor 130. The memory 131 is used to store computer programs, and the processor 130 runs the computer programs to enable the electronic device to perform the above method.

[0072] Further, combined with Figure 7 The electronic device shown further includes a bus 132 and a communication interface 133 , and the processor 130 , the communication interface 133 and the memory 131 are connected via the bus 132 .

The bus 132 may be an ISA bus, a PCI bus, or an EISA bus. The bus can be divided into an address bus, a data bus, a control bus, etc. For ease of representation, Figure 7 Only one bidirectional arrow is used in the diagram, but this does not mean that there is only one bus or one type of bus.

[0074] The processor 130 may be an integrated circuit chip with signal processing capabilities. During implementation, each step of the above method can be completed by hardware integrated logic circuits in the processor 130 or by software instructions.
