The Air Data Computer Integrated Test System

In today’s aircraft became an important means of transport and the air datacomputer can receive and analysis the original parameters to translate into the flightdata of plane.So the inspection and maintenance the air data computer is mostimportant, because it will directly affect the aircraft’s flight safety.In this paper design a integrated testing system to test the air data computer, itsrole to check the air data computer. Its main works is Simulation of air data computerrequired parameters, for example, total pressure, static pressure, andtemperature......,enter the data to the air data computer,when have the output data,comparison two kinds of output to know how equipment is needed to maintain.This article is divided into three major parts.Why do you want to design thesystem, the general structure of the system and hardware design.first, to introductionthe related concepts, principles, processes and roles of the air data computer, knowthe testing system to produce all kinds of output signal and its forms and Accordingto a variety of signals to determine the system’s structure.At last,design the hardware.In the hardware of this testing system.the receiver&transmitter is veryimportant.In this board,use the ARINC-429and HS-3282to transmit and receivedata.Use the14ZSZ1412to achieve the angle between it and the digital signalconversion.when its three input ports receive the output signal, Completesynchronous switching function. Outside of the decoding circuit also has delaycircuit,to host of high-speed operation and low run rate that fits the transceivercircuit, to increase the speed of data processing, and achieve optimal effect.Test system for air data computer in the field using a broad range of today’s civilspace, there are products of the same type. But compared with, automatic test systemdesign in this article, you can complete basic data collection, analysis and testing,low cost, small size, convenient belt, you can also use computer databases to managedocuments, you can lay the Foundation for further repairs.
