Portable avionics bus test system and internal data transmission method

Abstract

The invention relates to the technical field of aircraft development, and discloses a portable avionics bus test system and an internal data transmission method.The system comprises a portable simulation test terminal, a wireless routing subsystem and a mobile terminal subsystem; at least two wireless routers (21) are wirelessly connected with each other to form a hardware system of an aircraft ground test wireless network, and the wireless routing subsystem is in data transmission connection with a mobile terminal subsystem; the at least one portable simulation test terminal is in data transmission connection with the wireless routing subsystem so as to be in data transmission connection with the mobile terminal subsystem; the portable simulation test terminal collects and sends aircraft avionics bus data, and the mobile terminal subsystem receives and feeds back distributed bus data and performs graphical display and control. The method is high in universality and convenient and fast to use, the test coverage rate is increased, general assembly debugging and onboard ground tests are more sufficient, and therefore the confidence coefficient of test results is increased.

Description

technical field [0001] The invention relates to the field of aircraft development, in particular to a portable avionics bus test system and an internal data transmission method. Background technique [0002] With the rapid development of the aircraft avionics system, the functional performance of the aircraft has been greatly improved, and the safety, economy and comfort have also been greatly improved. However, the complexity of the avionics system itself is increasing, especially in the avionics system bus. network aspect. [0003] During the final assembly and ground commissioning stages of the aircraft, it is necessary to test the aircraft system as fully as possible on the aircraft. The current ground test equipment is relatively scattered and cannot form a system of interactive information. It is also difficult for the bus monitoring to share the avionics bus with the station that stimulates the sensor. The data mainly relies on the distributed input of more manpower ...

Problems solved by technology

[0003] During the final assembly and ground commissioning stages of the aircraft, it is necessary to test the aircraft system as fully as possible on the aircraft. The current ground test equipment is relatively scattered and cannot form a system of interactive information. It is also difficult for the bus monitoring to share the avionics bus with the station that stimulates the sensor. The data mainly relies on the distributed input of more manpower for intercom communication, which will result in more input personnel and corresponding support facilities, and it will not be possible to achieve accurate data exchange and status confirmation, and the efficiency is relatively low

In order to solve this problem, the industry has proposed a data communication solution based on wireless Ethernet to integrate ground test equipment, but it has not been realized due to insufficient network coverage, and the reliability and real-time performance of ordinary Ethernet communication cannot be guaranteed.
