Problems solved by technology

The quality of bus data transmission is not limited to the integrity of the protocol layer. For example, some buses have been tested by the protocol layer, and the bit error rate is still in the safe range, but the electrical characteristics of the signal are close to the critical state. For this Class bus cables still need repair

Abstract

The invention provides an aircraft ARINC429 bus dedicated quality comprehensive evaluation system, comprising a controller and a protocol layer test module, an electrical layer test module and a physical layer test module connected to the controller respectively, wherein the protocol layer test module is based on the interface control file The database detects the bit error rate and packet loss rate of the ARINC429 bus signal. The electrical layer test module detects the electrical parameters of the ARINC429 bus signal according to the relevant clauses in the ARINC429 specification. The physical layer test module is based on the spread spectrum time domain The reflection method is used to test the connectivity of the ARINC429 bus cable.

Description

technical field [0001] The invention relates to a bus quality evaluation system, in particular to an aircraft ARINC429 bus-specific comprehensive quality evaluation system. Background technique [0002] With the development and progress of aviation technology, electronic information, computer technology, control technology, etc., more and more electronic systems have been popularized due to their high efficiency, rapidity and reliability. Civil aircraft must ensure its safety and reliability, so the information interaction between avionics systems and some airborne sensors or other electronic devices has become a major problem in aircraft design. As the "skeleton" and "nerve" of the avionics system, the aviation data bus plays a vital role in improving the overall performance of the aircraft. [0003] In the development process of aviation bus, in order to improve its safety and reliability, a series of standards and specifications have been formulated. Airborne bus in civi...
