General aviation avionics system product testing and verification environment

Abstract

The present invention discloses a general aviation electronic task system product testing and verification environment. The environment comprises a general simulation excitation area, a dedicated test area and a distributed communication network. The general simulation excitation area contains simulation components, and is used for simulating test excitation data of the required test verification environment and accessing the data to the distributed communication network; the dedicated test area contains an interface conversion unit, and is used for accessing the avionics task product to the distributed communication network; and the distributed communication network is used for adopting the middleware technology based on the data distribution service to carry out coupling between the accessed simulated excitation data and the measured avionics product through the data subject, monitoring the process data and analyzing the results. According to the technical scheme of the present invention, an open structure is used, only configuration of the interface conversion unit and a small amount of simulation components is needed can provide the verification environment for the professional and technical products of different professions, repetitive construction is reduced to the greatest extent, the economy is considerable, and the development cycle of the test verification is greatly shortened.

Description

technical field [0001] The invention relates to the field of comprehensive simulation testing and verification evaluation of products related to avionics mission systems, and proposes a general testing and verification environment construction idea with an open architecture, flexible configuration, and good scalability. Background technique [0002] The test and evaluation of avionics mission system products is usually carried out by means of flight test or ground simulation verification. From the perspective of economy, due to the high cost of flight test, it is widely used to construct avionics mission test and verification environment in the laboratory by using information technology and network technology. The application of the high-coverage ground test verification experiment can ensure that the product is fully tested for function and performance before installation. [0003] At present, the construction of the test and verification environment for avionics mission sy...

Problems solved by technology

[0003] At present, the construction of the test and verification environment for avionics mission system products generally relies on project implementation or professional construction. Different projects need to implement their own verification environments. In addition, the test and verification environment for professional technical fields generally relies on the construction of professional laboratories. The verification of various professional directions The environment is independently constructed and self-closed, and there is no cross-linking with each other
