由于飞行测试数据采集和遥测系统引用了能提供动态控制能力的微型计算机,所以软件正日益成为机载数据系统的一个不可缺少的组成部分。通常,软件的重要性总是被机载系统的许多用户所低估,甚至迄今,他们还在担心能否把PCM数据循环图编程到电可编程序只读存储器(EPROM)并将它们插入机载硬件中去。由于较新的可编程序系统使用带有电可擦可编程序只读存储器(E~2PROM)和随机存储器(RAM)的微型计算机来提供实时工程单位(EU)显示和控制能力,因而机载软件就成为整个系统计划的一个中心环节。在这些数据采集系统中,实时数据显示和控制所提出的程序设计要求,使地面站的数据处理软件和飞机上的数据采集软件之间要有软件结构控制和一种软件(固件)连接变得非常重要。本文介绍飞行测试过程中新出现的这类问题的一种解决办法。
As flight test data acquisition and telemetry systems reference microcomputers that provide dynamic control, software is increasingly becoming an integral part of onboard data systems. Often, the importance of software is always underestimated by many users of airborne systems, and so far they are still concerned about the possibility of programming the PCM data cycle diagram to an electrically programmable read-only memory (EPROM) Go in hardware Newer programmable systems provide real-time engineering unit (EU) display and control using a microcomputer with electrically erasable programmable read-only memory (E-2PROM) and random access memory (RAM) Software becomes a central part of the overall system plan. In these data acquisition systems, the proposed programming requirements for real-time data display and control necessitate a software architecture control and a software (firmware) connection between the data processing software at the ground station and the data acquisition software at the aircraft Very important. This article describes a solution to such emerging issues in flight testing.
