摘　　要：遥测系统中信道的资源是十分有限的,在多参量遥测系统中采用通用型的数据采集系统将导致信道资源的浪费。在这种情况下,采用了可编程多采样率数据采集系统。目前在遥测系统中使用的多采样率数据采集系统具有专用性,不能用于常规的数据采集。因此,我们设计了一种新型的多用途程控采样模式遥测数据采集系统,它既可满足遥测的需要又适用于常规的数据采集。文中论述了应用多采样率的原因、系统的结构及工作原理,并详细地介绍了多采样率的实现方法。In telemetry system the signal channel resources are very limited.Using general purpose equal sampling rate data acquisition system in multiparameter telemetry system will cause waste of signal channel resources.So programmable diverse sampling rates data acquisition system should be used. At present diverse sampling rates data acquisition system used in telemetry system is specific system that cannot be used to make normal data acquisition.A new multipurpose and diverse sampling rates telemetry data acquisition system was developed.Not only can it be used to make normal data acquisition but also be used in telemetry.In this paper the cause to use diverse rates, system structure, principle and realize method of diverse sampling rates was discussed.
