Description

Technical Field

[0001] The present invention belongs to the field of avionics technology, and in particular relates to a universal communication protocol management tool. Background Art

[0002] During the aircraft development process, the interconnections between systems are complex, and the accuracy of signal interaction between systems depends on the precise definition of signal transmission interfaces. The interface control document (ICD) gives a detailed description of the electrical and electronic interfaces defined in the system specifications, and defines the interfaces between avionics systems and between avionics and non-avionics systems. Therefore, the accuracy of the content of each system interface control document is particularly important.

[0003] At present, the definition of signal interfaces between aircraft systems usually relies on manual compilation of ICD and manual maintenance. The signal interface definition is iterative, resulting in repeated ICD upgrades, increased labor costs, low work efficiency and other problems. Secondly, for systems with complex cross-linking relationships, changes to their ICDs may lead to synchronous upgrades of the ICDs of related cross-linking systems. However, at present, this change is entirely informed and maintained by manual labor, which can easily cause asynchronous changes in the ICDs of multiple systems, leading to subsequent software changes, repeated testing and other problems, which in turn affects the progress of model development. Especially when the model is in mass production, rapid reuse of ICDs, miniaturization of changes and reuse, etc. are particularly important. Summary of the invention

[0004] The present invention aims at the problems of the background technology and proposes a universal communication protocol management tool. Through the management and configuration of signal interface definition, the use of multi-configuration aircraft can be supported. The tool can realize the design of interface information between various devices of complex avionics systems, provide the function of querying the ICD database, and also provide rich management and maintenance functions to make ICD database management safer and more reliable, improve the efficiency of ICD design, and meet the complex ICD data management requirements.

[0029] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings of the embodiments.

[0030] Figure 1-3 It is a schematic diagram for explaining an embodiment of the generalized communication protocol management tool of the present invention.

[0031] A universal communication protocol management tool includes an account authority management module, a structure tree management module, an interface information management module, a baseline management module, and a flight management module.

[0032] The account authority management module is assigned authority according to the personnel's job role, mainly including three levels: administrator account authority, system administrator account authority, and visitor login account authority. The administrator account authority is the highest authority, with one account number and belongs to the aircraft-level software configuration major. The authority includes the three aircraft-level node functions of model, type, and system of the structure tree, the functions of adding, deleting, and modifying each system administrator account, adding, deleting, and modifying visitor login account, adding, deleting, and modifying different account authority functions, aircraft-level baseline establishment, adding, deleting, and modifying and exporting each signal interface definition. The number of system administrator accounts is determined according to the professional division of each model, and each system major has one to ensure the uniqueness of the data source. The authority includes the three system and device node functions of subsystem, equipment, and equipment attributes (detailed information, location and instance, input port, output port) of the structure tree, adding, deleting, and modifying and exporting each signal interface definition, and the establishment of system and equipment-level baselines. There are a number of visitor login accounts, which are all model research designers, and the authority only includes viewing and exporting each signal interface definition.

[0033] The structure tree management module is mainly used to create a device structure tree by model. The structure tree levels are divided into model, type, system, subsystem, device, and device attributes (detailed information, location information, input port, output port). The permissions for adding, deleting, modifying, and checking each node in the structure tree belong to the administrator account and each system administrator account according to the level.

[0034] The interface information management module is divided into five nodes, namely, detailed information subnode, location subnode, input port subnode and output port subnode, based on the specific device. The detailed information subnode mainly inputs and displays the name, model, part number, and input / output port of the device into a hyperlink; the location information subnode mainly inputs and displays redundant devices and tags of the same model; the input port subnode is divided into two levels of menus, the first level mainly inputs and displays the label bit information of each port and the bus information to which it belongs, and the second level mainly inputs and displays the signal detailed information corresponding to the label bit, and all information at both levels can be automatically exported to generate documents; the function settings of the input port subnode are the same as those of the input port submodule.

[0035] The baseline management module supports the principle of multiple baseline validity, which is mainly divided into two levels: system-based and aircraft-based baseline establishment. First, each professional establishes a system-level baseline, and then the aircraft-level baseline is established by grabbing the system-level baselines. Multiple baseline validity means that the signal interface information designed according to different configurations exists and is valid at the same time, avoiding repeated changes between different models caused by the latest version. At the same time, according to different aircraft configurations, the closest baseline can be copied and modified to quickly establish a new configuration aircraft-level baseline. All baseline content can be automatically exported and documented.

[0036] The sortie management module is mainly used in the aircraft batch production stage, when the configurations of various types of aircraft are exactly the same or there are slight differences. The configuration copy button designed by the tool can directly realize the reuse of signal interface definitions of aircraft of the same configuration; or the configuration copy modification button designed by the tool can realize the copying of similar configuration data first, and then make small modifications and reuse based on the configuration data. This button will limit the scope of modification to avoid large-scale changes. For large-scale configuration changes, it is necessary to re-establish baselines at all levels in the above-mentioned baseline management module to confirm the final configuration. All configuration information can be automatically exported and documents can be generated.

[0037] So far, the purpose of the present invention has been achieved.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
