Description

Technical Field

[0001] The present application relates to the technical field of avionics systems, and in particular to an avionics data network configuration method, apparatus, computer equipment, and storage medium. Background Art

[0002] To reduce manufacturing costs, modern civil aircraft integrate multiple avionics applications into a single system, the avionics core processing system. This system provides data processing, data transmission, and data interfaces for these avionics applications. To ensure critical safety, applications must not interfere with each other. Therefore, the system isolates each application in separate partitions. System integrators must configure the resources allocated to each partition to ensure it meets the needs of the avionics applications. Configuring the avionics data network is crucial.

[0003] The avionics data network consists of end systems, switches, and network cables, and is based on the ARINC 664 "Avionics Full-Duplex Interactive Ethernet" standard. The standard defines the concept of a virtual link, which is a logical, unidirectional connection representing a communication link from a source end system to one or more destination end systems. Multiple virtual links can use the same physical link using time-division multiplexing. The total transmission capacity of the avionics data network is limited. During network configuration, it is necessary to allocate resources to each virtual link as accurately as possible while leaving a certain margin. Excessive allocation will result in insufficient remaining resources to support other partitions. The goal of avionics data network configuration is to rationally configure virtual links, limit the time they occupy physical links, and enable multiple virtual links to complete data transmission at different times.

[0004] Virtual link configuration primarily involves two parameters: the virtual link's transmission period and the maximum length of data frames transmitted during each period. In ARINC 664 networks, the interval between two virtual link transmissions must be at least the period value. Therefore, if the transmission time of the previous virtual link increases, the scheduled transmission time of the current virtual link will be squeezed out and must be postponed until the previous link completes its transmission. This increases the latency of the current virtual link. This additional delay is also known as jitter, a phenomenon that must be minimized in network configuration. Furthermore, latency and jitter propagate and affect all subsequent virtual links. To ensure data network performance and stability, all configurations must be re-iterated and regenerated.

[0005] In typical civil aircraft development, a single configuration iteration can take anywhere from hours to days. During the actual integration process, avionics applications often undergo changes and iterations, inevitably requiring adjustments to the data network configuration. Consequently, updating and iterating existing network configurations is inefficient. Summary of the Invention

[0055] In order to better understand the above technical solution, the technical solution of the embodiment of the present application is described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiment of the present application and the specific features in the embodiment are detailed descriptions of the technical solution of the embodiment of the present application, rather than limitations on the technical solution of the present application. In the absence of conflict, the embodiment of the present application and the technical features in the embodiment can be combined with each other.

[0056] See also Figure 1 and Figure 2 As shown, an avionics data network configuration method provided by an embodiment of the present invention is used to perform steps S101 to S104:

[0057] Step S101: Acquire link information of each virtual link, where the link information includes a maximum frame length and a transmission period.

[0058] In this embodiment, the number of times the i-th virtual link is transmitted per interval TV can be calculated based on the data to be transmitted in the virtual link. i The communication should be done once, and each communication needs to transmit at most N i Bytes of data. Figure 3 As shown in the figure, the period value TV and maximum frame length N of the virtual link are determined based on the frequency of data sent by the network source within a certain period of time, the total amount of transmitted data, and the special needs of other data users. The configuration should ensure that the bandwidth of the virtual link is not less than the total bandwidth of the source data. Specifically:

[0059] By formula M i (kbit / s) = N i (kbit) / TV i (s) Calculate the bandwidth of the i-th virtual link;

[0060] By official tv i (s) = N i (kbit) / BPS (kbit / s) is used to calculate the transmission duration of the i-th virtual link;

[0061] Among them, M i is the bandwidth of the ith virtual link, N i is the maximum frame length of the i-th link information, TV i is the transmission period of the i-th link information, tvi is the transmission duration of the i-th virtual link, and BPS is the total bandwidth of the avionics data network.

[0062] Step S102: setting bandwidth packages according to link information of virtual links in the network, and allocating each virtual link to a corresponding bandwidth package.

[0063] In this embodiment, a series of bandwidth packages are set according to the virtual links in the network, and the virtual links are allocated to the corresponding bandwidth packages: according to the frame length and period, the transmission time of the data network is divided into a series of bandwidth packages, and the bandwidth package has three main properties: total bandwidth, transmission period and duration. Different from the prior art that directly allocates all virtual links to the full time period of network transmission, the present invention classifies the virtual links and allocates them separately in bandwidth packages. Among them, the bandwidth package is the key concept of the present invention to achieve the above advantages. Through the design of the bandwidth package, a large number of virtual links can be classified and configured separately, which reduces the configuration complexity and reduces the correlation between virtual links of different categories. Figure 4 As shown, the main attributes of the bandwidth packet include transmission period TB, start time t, and duration td.

[0064] In an optional embodiment provided by the present invention, the method further includes: setting the bandwidth packages in chronological order according to the start time t.

[0065] Step S103 : Calculate the total bandwidth, transmission period, and duration of each bandwidth packet based on the link information of each virtual link and the total bandwidth of the avionics data network.

[0066] In this embodiment, various parameter values ​​of the bandwidth package are determined, and the parameter values ​​include the total bandwidth, transmission period, and duration of the bandwidth package. Figure 4 In the example, virtual links 1 and 2 are allocated to bandwidth package 1, and virtual link 3 is allocated to bandwidth package 2. The bandwidth packages must meet the following conditions:

[0067] The transmission period TB of a bandwidth packet should be less than or equal to the minimum period TV of all virtual links in the bandwidth packet. min The total bandwidth of the bandwidth package is MB (kbit / s) = BPS × td / TB, which should be greater than or equal to the sum of the bandwidths of all virtual links within the bandwidth package. Suppose there are n virtual links in the bandwidth package, and the bandwidth of the jth virtual link is M j , then it should satisfy All bandwidth packets cannot overlap with each other in the time domain, and the bandwidth packets are set in chronological order by the start time t.

[0068] In an optional embodiment provided by the present invention, calculating the total bandwidth, transmission period, and duration of each bandwidth packet based on the link information of each virtual link and the total bandwidth of the avionics data network includes:

[0069] MB by Formula m =BPS×td m / TB m and formula Calculate the total bandwidth and duration of the mth bandwidth packet;

[0070] According to the bandwidth package MB m The minimum period TV corresponding to all virtual links in min , determine the transmission period TB of the mth bandwidth packet m ;

[0071] Among them, MB m is the total bandwidth of the mth bandwidth packet, td m is the duration of the mth bandwidth packet, n is the number of virtual links corresponding to the mth bandwidth packet, M p The virtual link allocated to the mth bandwidth package.

[0072] Step S104: setting a corresponding phase for each virtual link according to the link information of each virtual link.

[0073] Set the phase for the virtual link in the bandwidth package. Figure 5 As shown, in existing configuration technologies, multiple virtual links may need to transmit data at the same time. The virtual links compete with each other, and only one virtual link can transmit on time, while the others must be delayed for a period of time. This period of time is temporary and occurs outside the scheduling plan, which is also known as network transmission jitter. Jitter is one of the main factors affecting transmission efficiency and quality.

[0074] In order to eliminate jitter, it is necessary to set the phase for each virtual link in the bandwidth package. The phase is the difference between the start time of each virtual link transmission and the start time of the bandwidth package in the same bandwidth package, such as Figure 6 shown.

[0075] Set different phases for virtual links, and let the phase of the i-th virtual link be P i , then it should satisfy: Among them, tv j The time required for the jth virtual link in the corresponding bandwidth package to complete data transmission is denoted by ∑j=1 / 2. The delay of each virtual link is greater than or equal to the total transmission time of all previous virtual links, so no contention occurs.

[0076] Through the design of bandwidth packages, a large number of virtual links can be classified and configured separately according to the actual integration requirements, reducing configuration complexity, reducing the correlation between virtual links of different categories, and avoiding the impact of a small number of configuration changes on a large number of other virtual links.

[0077] Transmission phase design of virtual links: This design can isolate the transmission time of virtual links within the same bandwidth package, preventing network jitter caused by contention.

[0078] Bandwidth package-based data network configuration method: Based on the design of bandwidth packages and the transmission phase design of virtual links, a data network configuration method was invented to improve integration efficiency, reduce the complexity of network configuration update iterations, and reduce the cost of resident application testing and verification.

[0079] The present invention provides an avionics data network configuration method, which obtains link information of each virtual link, including a maximum frame length and a transmission period; sets bandwidth packages based on the link information of the virtual links in the network, and allocates each virtual link to a corresponding bandwidth package; calculates the total bandwidth, transmission period, and duration of each bandwidth package based on the link information of each virtual link and the total bandwidth of the avionics data network; and sets a corresponding phase for each virtual link based on the link information of each virtual link. Through the design of bandwidth packages, the present invention can classify and configure a large number of virtual links according to the methods required for actual integration, reducing configuration complexity and the correlation between virtual links of different categories. This prevents changes to a small number of configurations from affecting a large number of other virtual links. When changes to the configuration of a small number of virtual links are required, the impact on other virtual links is reduced or avoided. Consequently, during the integration process, it is not necessary to update and iterate all network configuration items, thereby improving integration efficiency.

[0080] In an application scenario provided by an embodiment of the present invention, taking a door control system application as an example, the allocated virtual links are shown in Table 1, and the total bandwidth of the avionics data network is BPS=100 Mbit / s.

[0086] Step 2: Configure a series of bandwidth packages based on the virtual links in the network. In addition to other factors that should be considered during configuration, the configuration is mainly based on the transmission period of the virtual links, as shown in Table 3.
