摘要

航天探测过程中探测器上各负载的参数表现对探测器性能评估、结构优化具有重要的意义。为解决这一问题,本文以某一探测器验证要求针对多路信号进行同时处理的需求,利用高性能的A/D转换芯片设计了一种以现场可编程门阵列(FPGA)为核心的多通道、高速数据采集存储装置,实现对16路模拟信号的实时采集、转换、编帧和数据存储,以及对LVDS传输数据的接收。然后通过GPIO总线实时传送给系统流程控制单元,也可以存储到Flash存储器中,通过千兆以太网实现与上位机之间的通信和外部遥测。实验结果表明,经过数据对比,采集数据与数据源一致,无丢帧、无错码,数据采集存储符合技术要求,实现了预期功能。

Abstract

The parameter performance of each load on the probe in the process of space exploration has great significance to the performance evaluation and structural optimization of the probe.In order to solve this problem,this paper designs a multi-channel,high-speed data acquisition and storage device with field programmable gate array (FPGA) as the core by using a high-performance A/D conversion chip to realize real-time acquisition,conversion,framing and data storage of 16 analog signals,as well as the reception of LVDS transmission data.Then it is transmitted to the system process control unit in real time through the GPIO bus,and can also be stored in Flash memory to realize communication and external telemetry with the host computer through Gigabit Ethernet.The experiment results show that after data comparison,the collected data is consistent with the data source,there is no frame loss and no error code,and the data acquisition and storage meet the technical requirements and realize the expected function.
