Description

Technical Field

[0001] The present invention relates to the technical field of airborne product ground tools, and in particular provides a method for parsing and generating a configuration file of a universal processing module. Background Art

[0002] With technological advancements, the Integrated Modular Avionics (IMA) platform has evolved from traditional standalone avionics systems to integrated avionics systems, achieving a highly modular and integrated approach. The majority of equipment consists of field-replaceable modules, enabling configurable, scalable, and reconfigurable control. This also improves system health diagnostics and fault tolerance.

[0003] According to the overall design requirements of the IMA platform, the CPM module is the main data calculation device of IMA. A single aircraft is equipped with 12-20 field-replaceable Common Processing Modules (CPMs). CPM modules communicate with each other through the ARINC664 network based on configuration files. Each CPM runs the corresponding software according to the resident application configuration.

[0004] In the IMA platform, each CPM module hosts approximately ten different applications. Each resident application has its own unique configuration file, which contains port information, message information, refresh rate, and other information related to the resident application. Because resident applications run on an operating system, the operating system also has its own independent configuration. Furthermore, each CPM module generates a module configuration file based on the configuration of the resident application and the connections between CPMs. Consequently, the IMA platform can contain as many as 150-200 CPM-related configuration files.

[0005] Part of the input of the CPM configuration file comes from the interface control document released by the host, and part of the input comes from customer needs. Generating multiple CPM configuration files has become a relatively complex technical point, which involves a large number of input and output files, complex input sources, many parameter attributes, close relationships between configuration files, and a complex logical mapping and conversion process.

[0006] Therefore, it is necessary to provide a tool for systematically generating CPM configurations to solve the above problems. Summary of the Invention

A person of ordinary skill in the art will understand the specific meanings of these terms in the context of this application based on specific circumstances.

[0050] The interface control document is a collection of XML files. The interface control document usually contains information about each subsystem's hardware, resident applications, resident functions, logical buses, and network resource configurations. Figure 1-2 As shown, a method for parsing and generating a general processing module configuration file is provided, the method comprising:

[0051] S1: Generate application configuration subfiles for all applications residing on the CPM based on the interface control document. Each application's corresponding configuration file is configured with the required memory, including the code segment, data segment, and BSS segment (uninitialized global data segment), as well as the application's transceiver port information, message information, port refresh rate, and other information.

[0052] S2: Generates a schedule configuration subfile for each resident application on a CPM based on the interface control document. This subfile configures the order and runtime of the resident applications. Different applications run in each aircraft state, with a different number of resident applications on each CPM and different runtimes for each application. Each CPM module runs a partitioned application at the same time, so each CPM module has its own schedule. The schedule configuration file includes information such as the schedule ID, resident application name, and resident application runtime.

[0053] S3: Design operating system requirements and fill in an Excel sheet. Fill in the operating system requirements in the Excel sheet and generate an operating system configuration sub-file.

[0054] S4: Design and fill in the Excel sheet with other configuration information requirements for the application, fill in the Excel sheet with other configuration information requirements for the application and generate a configuration sub-file for other configuration information of the application;

[0055] S5: Design health monitoring requirements and fill in the Excel sheet. Fill in the user requirements in the Excel sheet.

[0056] S6: Generate a general processing module configuration file by filling out an Excel sheet based on the application configuration subfile generated by S1, the schedule configuration subfile generated by S2, the operating system configuration subfile generated by S3, the application other configuration information configuration subfile generated by S4, the interface control document, and the health monitoring requirements filled out in S5.

[0057] In some embodiments, the S1 includes:

[0058] S1.1: Analyze the configuration requirements of the general processing module. The application configuration sub-file should have an application memory size sub-node and an application port sub-node. The application memory size sub-node contains the memory requirements of the resident application for the CPM. The application port sub-node contains the configuration of the port information in the resident application. The application port is divided into QueuingPort and SamplingPort.

[0059] The application memory size node configuration information table is shown in Table 1:

[0060] Table 1 Application memory size node configuration information table

[0061]

[0062] The configuration information of the application port subnode is shown in Table 2:

[0063] Table 2 Application port node configuration information table

[0064]

[0065] S1.2: Traverse the interface control document and, using a hash table-based data structure, retrieve the application memory size node configuration information from S1.1 in the various XML files in the ATA 42 IMA\Hosted Applications\Classes folder within the interface control document. This method significantly improves the efficiency of searching for attributes in XML files.

[0066] S1.3: Traverse the interface control document and obtain the application port node configuration information in S1.1 in the XML file in different XML files under the ATA 42 IMA\Hosted Applications\Instance folder in the interface control document using a hash table-based data structure to generate an application configuration sub-file.

[0067] In some embodiments, the S2 includes:

[0068] S2.1: Analyze the schedule table attribute information contained in the schedule table configuration sub-file. The schedule table configuration sub-file configuration information is shown in Table 3 below:

[0069] Table 3 Schedule table configuration sub-file configuration information table

[0070] property definition Name Schedule name. Different aircraft states have different schedules. PartitionName Resident application partition name Duration Application runtime ;

[0071] S2.2: Traverse the interface control document and obtain the attribute information in S2.1 in the XML files APR_LEFT.xml and APR_LEFT.xml in the ATA 42IMA\Hardware\Instances folder of the interface control document using a hash table-based data structure.

[0072] S2.3: Generate application configuration sub-file.

[0073] In some embodiments, the S3 includes:

[0074] S3.1: Analyze core operating system configuration attribute information and partition operating system configuration attribute information;

[0075] S3.2: Design an Excel spreadsheet based on the attribute information obtained in S3.1. The Excel spreadsheet includes the attribute information name, attribute information description, and attribute information constraints.

[0076] S3.3: Design an Excel spreadsheet based on the attribute information obtained in S3.2 to generate an operating system configuration subfile.

[0077] In the above embodiment, since resident applications run on an operating system, each resident application has different requirements for operating system resources. However, the interface control document does not include the resident application's configuration of the operating system. Therefore, an Excel document is created to allow users to customize these requirements. Operating systems are divided into core operating systems and partitioned operating systems, so different requirements forms need to be constructed and filled in.

[0078] In some embodiments, the core operating system configuration attribute information includes core configuration information, core operating system memory size configuration information, and hardware configuration information; and the partition operating system configuration attribute information includes shared library configuration information.

[0079] In some embodiments, fill in the configuration under the core configuration sub-node to define the parameters of the core operating system, including system clock frequency, non-safe system call waiting time, whether to prohibit the core operating system dynamic partition space, partition logical address start address, operating system logical address start address, etc. The core configuration node configuration information is as shown in Table 4 below:

[0080] Table 4 Core configuration node configuration information table

[0081] property definition sysClkRateHz System clock frequency memoryAllocationDisabled Disable dynamic space allocation, true(1) or false(0) partitionVirtualAddress Partition logical address starting address. kernelVirtualAddress Operating system logical address starting address addressSpaceSize Logical space size. addressSpaceRegionAllocationUnit The smallest logical space allocation unit.

[0082] Fill in the configuration under the Core OS Memory Size subnode to describe the size of each segment of the core OS, including the code segment, data segment, read-only data segment, and BSS segment. The Core OS Memory Size node configuration information is shown in Table 5 below:

[0083] Table 5 Core operating system memory size node configuration information table

[0084] property meaning MemorySizeBss BSS segment size MemorySizeData Data segment size MemorySizeRoData Read-only data segment size MemorySizeText Code segment size

[0085] As part of the core operating system configuration, physical memory configuration requires the design of configuration information under the hardware configuration sub-node. The configuration information of the hardware configuration node is shown in Table 6 below:

[0086] Table 6 Hardware configuration node configuration information table

[0087]

[0088] The root node of the partition operating system configuration subfile is the shared library configuration, which defines the properties of the shared library. Shared libraries are a way to implement code sharing between multiple applications. Shared libraries are not dynamically loaded. At system startup, all software must be loaded into a fixed and non-overlapping memory space; at module startup, all libraries must be loaded into the memory space. Code that multiple applications need to access can be designed as a shared library. In most cases, the shared libraries required by all partitions in a module are included in the partition operating system. The configuration information of the shared library configuration node is as follows:

[0090] property meaning SystemSharedLibrary Whether to configure system shared libraries. VirtualAddress Logical start address of the shared library MemorySizeText Shared library code segment size MemorySizeRoData Shared library read-only data segment size MemorySizeData Shared library data segment size MemorySizeBss Shared library BSS segment size

[0091] In some embodiments, the S4 includes:

[0092] S4.1: Analyze the attribute information required by the application's other configuration information configuration sub-file. The attribute information required by the application's other configuration information configuration sub-file includes application initialization attribute information, application process attribute information, and schedule table switching attribute information. The configuration information tables for each information are shown in Tables 8, 9, and 10 below:

[0111] Table 11 Health monitoring configuration information

[0112]

[0113] In the method provided in the above embodiment, the CPM module configuration file can automatically create all CPM configuration files by importing the interface control document and user requirements (Excel spreadsheet), including the application software configuration file, operating system configuration file, and CPM module configuration file resident on the CPM, thereby ensuring the consistency of the parsed configuration files and the interface control document. At the same time, for user-defined requirements, a concise and intuitive Excel spreadsheet is provided to the user for easy filling. As the main device for data calculation on the IMA platform, the CPM module can quickly and flexibly modify the CPM module properties through the configuration file. At the same time, the use of the configuration file reduces a large amount of code development work for developers. When the requirements change, the settings of the CPM module can be quickly iterated by changing the relevant properties of the configuration file.
