在七十年代国外的航天领域,遥测技术和微计算机技术的结合,产生了崭新的一代遥测系统,它具有自适应性、通用性和高可靠性等一系列根本区别于经典遥测系统的特点。这种新型的遥测系统,大致上又可以分成三种类型:(1)存储器控制的可编采样程式遥测系统;(2)以微处理机为核心的遥测系统;(3)遥测、遥控和数据处理综合系统。本文首先通过典型例子分别介绍这三类系统的原理结构,然后从许多实例中,提炼出一些值得注意的技术问题进行讨论。最后介绍发展趋势。
In the field of spaceflight abroad in the seventies, the combination of telemetry and microcomputer technology resulted in a new generation of telemetry systems featuring a range of features that are fundamentally different from classical telemetry systems in terms of adaptability, versatility and high reliability. The new telemetry system can be roughly divided into three types: (1) memory-controlled programmable sampling telemetry system; (2) microprocessor-based telemetry system; (3) telemetry, remote control and data Processing integrated system. This paper first introduces the principle structure of these three kinds of systems through typical examples. Then from many examples, some technical problems worth noting are discussed. Finally introduce the development trend.
