Description

Technical Field

[0001] This application relates to the field of rail transit technology, specifically to an MVB automated experimental configuration system and method, electronic equipment, and storage medium. Background Technology

[0002] The network control system data interface configurations of various train products are diverse. The existing hardware resources of the hardware-in-the-loop simulation test platform cannot keep up with business needs. Furthermore, due to limitations in site space and distance, existing resources have to be disassembled and reused. Some test benches have issues with performance degradation or hardware damage, which prolongs the test bench construction cycle, prevents sufficient pre-production verification, and results in higher management costs and resource losses.

[0003] In related technologies, train electrical control software testing mainly employs hardware-in-the-loop (HIL) simulation testing methods. A HIL simulation platform typically includes an electrical cabinet, network equipment, hard-wired connections, and a software simulation system. Specifically, for testing the vehicle-level bus (MVB, Multifunction Vehicle Bus), the connection method is based on the specific topology of the train's network under test, and connections are established in a fixed manner by manually plugging and unplugging cables.

[0004] For different test projects, due to the different MVB network topology connection methods, existing hardware-in-the-loop (HIL) test benches often need to be manually modified or rebuilt. This process not only consumes a lot of manpower, material resources, and time, but also the frequent plugging and unplugging operations can easily lead to wear and tear on interfaces and cables, affecting the stability and reliability of the test, resulting in a long overall design and testing cycle and low efficiency.

[0005] Therefore, there is an urgent need to build a test environment that can realize automated experimental configuration based on the topology of the network system of the train under test. Summary of the Invention

Detailed Implementation

[0015] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0016] In the process of developing this application, the inventors discovered that the MVB bus testing configuration in the related technologies suffers from problems such as reliance on manual labor, low efficiency, and poor flexibility.

[0017] To address the aforementioned issues, this application provides an automated MVB experimental configuration system. This system utilizes a programmable switch matrix to achieve automated configuration connections for the MVB bus, enabling the train network system under test to automatically, quickly, and flexibly configure hardware simulation resources according to simulation testing requirements. This improves testing efficiency and reliability, and solves the problems of manual reliance, low efficiency, and poor flexibility in related technologies for MVB bus testing configurations.

[0018] This application provides an MVB automated experimental configuration system, including: Multiple vehicle-mounted physical units, each having an MVB communication port; The simulator is equipped with multiple MVB emulation communication interfaces; A programmable multiplexer matrix is ​​electrically connected to the MVB communication port of the vehicle-mounted physical unit and the simulator, and is used to control the on / off state of the communication link between the ports. The first control unit is used to receive topology requirement instructions from the host computer and control the state switching of the corresponding switches in the programmable multiplexer matrix according to the instructions, so as to realize the automated physical connection configuration of the MVB network.

[0019] The MVB automated experimental configuration system of this application replaces traditional manual wiring with a programmable switch matrix, achieving automated and rapid configuration of the test topology. This reduces the configuration time from hours or even days to seconds, significantly improving simulation configuration efficiency. It also enables dynamic, on-demand reuse of hardware resources, avoiding hardware performance degradation or interface damage caused by repeated disassembly and reassembly, thus improving resource utilization and the long-term reliability of the entire test system. Through modular design and programmable internal and external connections, it can be flexibly combined to support various complex MVB network topologies. By simply adding physical modules, the system can be easily expanded to simulate longer and more complex train networks, meeting future business development needs and enhancing the system's flexibility and scalability.

[0020] In an optional embodiment of this application, see [link to relevant documentation]. Figure 1The onboard physical unit may include four integrated control units (CCUs) (such as CCU1, CCU2, CCU3, and CCU4) and two human-machine interface (HMI) units (HMI1 and HMI2) for human-machine interaction. Each CCU and HMI has an MVB communication port. The simulator may include four MVB simulation communication interfaces to simulate the communication of other onboard devices (without physical components in the system). The programmable multiplexer matrix may consist of multiple high-frequency relays to achieve routing switching of MVB bus signals. The first control unit is used to receive instructions from the host computer and control the on / off state of each switch in the programmable multiplexer matrix. The MVB four-segment mode includes, but is not limited to, [examples of MVB four-segment modes]. Figures 1 to 3 The example shown is in Figure 1 In this system, by closing switches KA1-KA8 and opening switches KA9-KA12, CCU1, CCU2, CCU3, and CCU4 can be divided into four independent network segments. Furthermore, HMI1 and HMI2 can be connected to any network segment by controlling the on / off state of KA13-KA22. Figure 2 In this configuration, CCU1 to CCU4 are connected to their respective emulator MVB interfaces. By closing KA13, KA14, KA21, and KA22, HMI1 and HMI2 are simultaneously connected to the network segment where CCU1 resides. Figure 3 In this case, HMI1 and HMI2 can be connected to the network segments where CCU2 and CCU3 are located by closing KA15 to KA18.

[0021] In an optional embodiment of this application, the MVB two-segment mode allows CCU1 and CCU2 to be connected to the same network segment and CCU3 and CCU4 to be connected to another network segment by closing switches KA1, KA2, KA5, and KA6 and opening switches KA3, KA4, KA7, and KA8. Alternatively, HMI1 and HMI2 can be connected to any network segment by controlling the on / off state of KA17-KA22. Figure 4 In the configuration, CCU1 and CCU2 are connected in series to MVB interface 1 of the emulator, and CCU3 and CCU4 are connected in series to MVB interface 3 of the emulator. HMI1 and HMI2 are connected to the two network segments respectively by closing KA17-KA20. Figure 5 In this case, HMI1 and HMI2 can be connected to the network segments where CCU3 and CCU4 are located simultaneously by closing KA19 to KA22.

[0022] In an optional embodiment of this application, the MVB three-segment mode can be divided into three segments by controlling a switch to group CCU1 and CCU2 into the same segment while keeping CCU3 and CCU4 as independent segments, or to group CCU3 and CCU4 into the same segment while keeping CCU1 and CCU2 as independent segments.

[0023] The MVB automated experimental configuration system of this application is equipped with a programmable multiplexer matrix, which connects the MVB ports of multiple CCUs and HMIs to the matrix. By controlling the on / off state of the switches within the matrix, arbitrary combinations of physical MVB connections between multiple CCUs and HMIs can be achieved. This is a key difference from the manual wiring in existing technologies.

[0024] In the MVB automated experimental configuration system of this application, for the four CCUs and two HMIs of the vehicle-mounted physical unit, no more than four switches are implemented in any mode link and no more than three switches are implemented in the common mode (one HMI) link, so as to minimize the impact of switches on the communication link.

[0025] In an optional embodiment of this application, the vehicle-mounted physical unit includes a plurality of second control units and at least one human-machine interface unit, wherein the control units and the human-machine interface unit are connected to the programmable multiplexer matrix through their respective MVB communication ports. In an optional embodiment of this application, the programmable multiplexer matrix is ​​configured to divide the plurality of vehicle-mounted physical units into several MVB communication network segments through switch combinations, or to dynamically connect the human-machine interface units to different MVB communication network segments. In an optional embodiment of this application, the switches in the programmable multiplexer matrix are high-frequency relays; and / or, the system further includes reconnection switches configured between different modules. The MVB automated experimental configuration system of this application adopts a physical modular design, and the modules are connected through dedicated reconnection switches. This two-level configuration of "intra-module programming" combined with "inter-module programming" gives the system good scalability and can flexibly simulate MVB networks of different sizes.

[0026] In one optional embodiment of this application, the host computer generates a target MVB network topology based on predetermined test cases and sends the target MVB network topology to the control unit. In an optional embodiment of this application, the system simulates train MVB networks of different sizes by adding the onboard physical unit and expanding the programmable multiplexer matrix.

[0027] The MVB automated experimental configuration system of this application, from topology requirements to physical connections, can automatically parse and convert the upper-level, logical MVB topology requirements into lower-level hardware control instructions for the switch matrix, thereby realizing an end-to-end automated configuration process.

[0028] This application also provides an MVB automated experiment configuration method implemented according to the MVB automated experiment configuration system, including the following steps: Receive topology requirements, wherein the topology requirements indicate the target MVB network topology; Based on the target MVB network topology, the on / off state control commands for each switch in the programmable multiplexer matrix are parsed out. The control command is sent to the programmable multiplexer matrix to control the state switching of the corresponding switch; After the programmable multiplexer matrix operates according to the instructions, it completes the construction of the physical connection path of the MVB bus, forming a real experimental environment consistent with the target topology.

[0029] The MVB automated experimental configuration method of this application receives topology requirements, uses host computer test management software to determine the target MVB network topology based on test cases, parses the target topology into a set of specific switch on / off state commands, and the control unit sends the commands to the programmable multiplexer matrix of one or more physical modules and the reconnection switches between modules to execute switch control. The switch matrix and reconnection switches act according to the commands to complete the physical path connection of the MVB bus, automatically constructing an experimental environment completely consistent with the target topology, and completing the automatic configuration. It realizes the automatic construction of MVB network topology through modularity and programmability, and realizes the automated configuration connection of MVB bus through programmable switch matrix. It overcomes the defects of existing technologies that rely on manual labor, are inefficient, and lack flexibility in MVB bus test configuration, enabling the train network system under test to automatically, quickly, and flexibly configure hardware simulation resources according to simulation test requirements, thereby improving test efficiency and reliability.
