[0016] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0017] See also Figure 1 , a multi-rate TSN endpoint physical simulation platform, comprising:

[0018] Optical communication carrier board, used to provide power supply interface, communication interface and debugging interface for the simulation slot;

[0019] The simulation slot is used to connect the communication CPU card and the multi-rate TSN communication card to perform simulation experiments; the simulation slot is provided with multiple ( Figure 1 For specific 4 simulation slots);

[0020] The communication CPU card and the multi-rate TSN communication card introduce the working voltage through the power supply interface, the communication CPU card and the multi-rate TSN communication card realize communication through the communication interface, the communication CPU card and the multi-rate TSN communication card are connected to the debugging computer through the debugging interface (serial port output is also provided to connect to the debugging computer); the communication CPU card and the multi-rate TSN communication card are connected through the PCIEX4 channel provided by the optical communication carrier board.

[0021] In the specific embodiment: see Figure 1 , in the prior art:

[0022] 1. The unified TSN network operation test is subject to the completeness of each endpoint, and the overall network service cannot be physically verified in advance.

[0023] 2. The business software platforms of different physical endpoints are inconsistent, and the workload of TSN business software development and coordination in airborne systems is huge.

[0024] 3. The design of different endpoints is not flexible. When the transmission rate and topology change, it is impossible to make timely adjustments and perform physical simulation work.

[0025] The utility model:

[0026] 1. The multi-rate TSN endpoint physical simulation platform can carry out physical verification work in advance when the onboard endpoint equipment is not complete. It verifies the overall plan through physical experiments, improves the overall service design quality of the TSN network, and reduces rework.

[0027] 2. The multi-rate TSN endpoint physical simulation platform provides a unified software development environment (Vxworks6.9). The same host computer can configure and run multiple endpoints, reducing the difficulty of development and verification.

[0028] 3. The multi-rate TSN endpoint physical simulation platform can provide physical simulation work for 4 slot endpoints. These four slots can flexibly support configuration into 4X1G, 4X10G, 3X1G-1X10G, 2X1G-2X10G, 1X1G-3X10G and other endpoint physical simulation environments, so that when the topology design changes in the airborne environment, the network can be quickly formed and physical testing can be carried out, greatly improving the efficiency of TSN network system design verification.

[0029] In this example: See Figure 1 The communication CPU card is the core daughter card of POWER PC P1011, and the communication CPU runs the VxWorks6.9 operating system.

[0030] The communication CPU card uses the core daughter card of POWER PC P1011, which is connected to the optical communication carrier board through the FMC connector. The communication on the plug-in uses the PCIEX4 channel to connect to the multi-rate TSN communication card, and at the same time leads to the serial port and network port signals for CPU debugging, and the power supply introduces the 5V power supply voltage provided by the optical communication carrier board. The VxWorks6.9 operating system is uniformly run on the CPU.

[0031] In this example: See Figure 1 The multi-rate TSN communication card is XILINX’s K7325T FPGA, which runs TSN communication logic IP and driver software.

[0032] The multi-rate TSN communication card uses XILINX's K7325T FPGA as the TSN communication service daughter card hardware, on which TSN communication logic IP and driver software are run. It provides a DMA data reading channel for the same communication CPU card. The multi-rate TSN communication card and the optical communication carrier board are connected through the FMC plug-in. The communication on the plug-in uses the PCIEX4 channel to connect to the communication CPU card, and the power supply introduces the 5V power supply voltage provided by the optical communication carrier board.

[0033] In this example: See Figure 1 The communication interface realizes the photoelectric conversion function of the high-speed optical data transceiver channel through the HTA8537 and HTA8538 modules of AVIC Optronics.

[0034] AVIC's HTA8537 and HTA8538 modules use MT bundled optical fibers for signal input and output.

[0035] In this example: See Figure 1 The power supply interface completes the voltage conversion through a voltage regulator, converting the 12V voltage into 5V and 3.3V.

[0036] The voltage supply is achieved by converting 12V to 5V, 12V to 3.3V or 5V to 3.3V through a voltage regulator.

[0037] The working principle of the utility model is: the utility model has four independent slots, each slot can be installed through a board, and a 1G or 10G physical simulation card is flexibly combined, and the physical simulation card has a unified software development platform (Vxworks6.9). Solve the physical testing needs of airborne TSN bus network services when the service endpoint equipment is not complete. At the same time, quickly network and carry out physical verification work when the overall network environment topology design changes. This application can support 4 TSN communication endpoint physical simulation slots, and each slot can be flexibly configured with a rate, which is convenient for flexible networking according to different topology requirements. The protocol implementation and communication software design of TSN are executed in accordance with the TSN standard protocol. Although this application has only four slots, more TSN physical simulation endpoints can be expanded by connecting multiple devices in parallel to meet larger-scale TSN physical simulation needs.

[0038] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, the embodiments should be considered as exemplary and non-restrictive in all respects.

[0039] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
