Problems solved by technology

[0004] Compared with the actual installation and test flight, digital verification methods are relatively cheap and convenient, but these digital development environments are usually composed of complex aircraft, equipment and other mathematical models, computer systems and professional development tools, and most of them are developed by European and American professional manufacturers. Software upgrade fees are still pretty staggering
[0005] A shortcoming of the digital development environment is that it does not solve the problems of effectiveness, conformity and authenticity, especially to meet the operational test in the actual flight of China's civil aviation

Embodiment 1

[0082] Such as figure 1 As shown, a civil aircraft avionics verification system based on aviation data link information, including:

[0083] The receiving device of aviation data link information is used to receive aviation data link information; civil full-band radios, industrial broadband receivers, purchased or self-developed data link receivers can be used;

[0084] The low-cost solution is to directly purchase civil full-band radios on the market, and receive ACRAS broadcast message information on its civil aviation frequency band. The price range of this kind of radio is from a few hundred yuan to more than a thousand yuan each.

[0085] Industrial broadband receivers can receive signals more stably. Broadband receiver is a general term for all kinds of radio receiving equipment in the frequency range of 30~1000MHz. It can be in the form of landline, mobile phone, or car receiver, and the price is relatively low.

[0086] It is also possible to develop or purchase ACA...

Embodiment 2

[0101] A civil aircraft avionics verification method based on aviation data link information, comprising the following steps:

[0102] 1) The receiving step of the aviation data link information, receiving the aviation data link information, and providing high-fidelity actual flight parameters for the simulation system;

[0103] 2) The data link decoding step is to decode the received aviation data link information; after completing the decoding of all data in the data link, screening and preprocessing may not be performed to simplify the function of the data link decoding module;

[0104] 3) The configuration management step is used for: A, screening the required information in the aviation data link, and sorting it into the required format, storing it in the database to form the required dynamic data source for the high-fidelity digital development environment; B. Call out relevant data from the database according to the requirements of high-fidelity verification in the comp...

[0118] Implementation Case: Software Design Verification of Flight Management System

[0119] The test use scenario is the actual operation data of the air corridor in the Shanghai-Hangzhou airspace.

[0120] As an example, take the air corridor from Shanghai Jiuting waypoint to Zhejiang Tonglu waypoint for data statistics, classification and data use cases for verification and comparison.

[0121] The first step is to receive the data of the data link, and use the database software to record and classify the actual data.

[0122] An example of the format of the actual data statistics table is as follows.

[0123] 1. Organize route-related data. According to the route information released by the Civil Aviation of China, the route data from Shanghai Jiuting to Tonglu, Zhejiang is shown in Table 1.

Abstract

The invention relates to an aeronautical data chain information-based civil aircraft aviation electronic verification system and a method thereof. The civil aircraft aviation electronic verification system comprises an aeronautical data chain information receiver, a data chain decoding module, a configuration management module, a database module, a verification platform tool module, a task module, a contrastive analysis application module and an analysis terminal, wherein the database module is used for storing machine type data and performance data of an airplane, local civil airline data and actual flight data; the task module is used for calling the data in the database module according to tasks and acquiring actual track path data which is needed by contrastive analysis verification and is generated based on the aeronautical data chain information; and the contrastive analysis application module is used for comparing the data of a verified object acquired by the verification platform tool module with the actual flight data of the task module, and providing a digital difference value report or a track goodness of fit report according to a comparison point set by a user. The civil aircraft aviation electronic verification system and the method thereof support a digital development environment through the current civil aviation communication data chain technique so as to provide a vivid testing or verifying means for an avionics system.

Description

technical field [0001] The invention belongs to the technical field of civil aircraft avionics systems, and in particular relates to an avionics verification system, a flight management system, and a verification system for aviation data link communication technology and a method thereof. Background technique [0002] Contemporary civil aircraft avionics equipment and systems cover the fields of aeronautical communications, aviation instruments, computers, atmosphere, navigation and positioning sensors, and become a comprehensive discipline that develops independently of specific aircraft design. have an increasingly important impact. Therefore, the research and development process requires repeated verification and iteration to achieve more optimized results. [0003] The avionics system should have relatively low research and development costs while meeting the technical specifications of the aircraft, so that users can afford it and use it. For this reason, more and mor...
