摘要: 介绍一种机载飞控系统飞控计算机对各种控制信息（包括离散量、模拟量和串行数据）进行数字化控制、实时采集、监控和处理的接口模块设计方法，从工程应用角度出发，阐述了模块的设计思路以及工程实现，给出原理框图和测试流程。在某型飞机的实际应用中，实现了32路离散量输入输出、16路模拟量输入输出、6路ARINC429串行数据收发、4路ARINC422串行数据收发以及4路ARINC232串行数据收发的功能，自测试覆盖率达100%。因该模块的接口形式和接口数量可根据实际需要进行增减，故具有很强的典型性和通用性，可适用于各类型的机载飞控系统。Abstract: A design method based on the interface module of airborne flight control computers, which could realize digital control, real-time acquisition, monitoring and processing of various control signals (including discrete magnitude, analog quantity and serial data), was introduced. Focusing on the engineering application, the design idea and implementation methodology of the module were elaborated, as well as the self-tesing, with the illustration of principle block diagrams and testing process. In the application of a certain air freighter, the module performed the functions of the input and output of 32 interfaces discrete magnitude, the input and output of 16 interfaces analog quantity, the transceiving of 6 interfaces ARINC 429 serial data, and the transceiving of 4 interfaces ARINC 232 serial data, with the coverage of self-testing reaching 100%. The flexibility of the form and the number of the module interface enables the adjustment in accordance with the actual application; therefore the module is featured with evident typicality and generality, which can be used in various types of airborne flight control systems.
