Test platform of bleed air monitoring computer

Abstract

The invention discloses a test platform of a bleed air monitoring computer, which comprises a test platform body and control software, wherein the software is matched with the test platform and accords with an ARINC (Aeronautical Radio Incorporated) 429 protocol; a panel of the test platform body is provided with discrete signal switches, test holes, status indicator lamps, a socket and a connector; and the test platform body provides a power supply signal, analog input, discrete signal input and input of an ARINC 429 data signal, converts a discrete signal output by a UUT (Unit Under Test) and the ARINC 429 data signal into output signals of the status indicator lamps and the socket for output, and performs an electrical test on a transmission channel. Compared with the existing test platform, the test platform is very simple in overall structure; since the test platform adopts a digital technology, and the related electronic devices are ordinary electronic components, the manufacturing cost and the maintenance cost of the test platform are very low, and are lowered greatly in comparison with the prior art.

Description

technical field [0001] The invention relates to a test bench for a bleed air monitoring computer of aviation equipment, in particular to a test bench for a bleed air monitoring computer. Background technique [0002] At present, the maintenance equipment for testing the bleed air monitoring computer at home and abroad is mainly the test equipment of INTERTECHNIQUE company, but it is necessary to distinguish the part number of the bleed air monitoring computer to select the corresponding test equipment. Although the test equipment of INTERTECHNIQUE company can satisfy the test of bleed air monitoring computer, due to its high price and limited scope of application, the test and maintenance of a single bleed air monitoring computer is relatively cumbersome, and it is not convenient for people to purchase and use. Contents of the invention [0003] Aiming at the problems existing in the above-mentioned prior art, the purpose of the present invention is to provide a kind of de...
