Design and implementation of a configurable sample-encoder based on modularity method

针对飞行器被测信号种类和数量不断增多带来的遥测系统采编器多样化、定制化的问题,设计并实现一种模块化可配置采编器。采用模块化设计理念,对采编器进行硬件和软件模块化设计,实现采编器各类需求间组合和裁剪的能力;通过可配置协议设计和可配置物理设计,实现采编器适配相应遥测系统需求的能力。经过大量试验验证,采编器良好适配各类遥测系统需求,缩短设计周期,降低设计成本,具有较高的可靠性和工程应用价值。

With the development of space vehicle,the demands of telemetric signal have increased in variety and quantity.The sample-encoder,the key device in telemetry system,becomes application specific and implementation complex.In order to solve this problem,a configurable sample-encoder based on modularity method is designed and implemented.Firmware and hardware have been redesigned using modularity method to make it composable and decomposable.A configurable protocol and a practical plan are made to adapt for every particular telemetry system.As a consequence,numerous tests show that this sample-encoder is well applied to several telemetry systems reliably and its design cycle and costs have been reduced considerably,the application prospect of this device can be attractive.
