【摘要】：作为测控系统的重要组成部分，固态存储器在测控系统中有着不可替代的作用，它是获得飞行器飞行状况信息的主要途径，为飞行器系统的性能评定、故障分析和设计生产改进提供可靠的试验依据。本文设计和实现的固态存储器完成模拟量的采集和数字量的接收，并将接收的数据存储。在试验完成以后，可以将固态存储器进行硬回收，将存储器存储的数据读出以作后期的分析和处理。 针对基于双平面技术的固态存储器，根据模块化和高可靠性的设计思想，结合固态存储器的任务要求和性能指标，本文提出了固态存储器的总体设计原则和设计方案，，并主要完成了以下工作： (1)以FPGA为控制核心，完成6路模拟量的采集和2路PCM码流的接收，将采集的模拟量和接收的数字量进行再编码，并将再编码后的数据进行混合编帧。 (2)详细介绍了使用双平面技术进行块擦除、将混合编帧的数据进行页编程和在时候将数据回读的时序，并对双平面技术在固态存储器中的应用作了相关的验证。 (3)介绍了试验中进行实时监测以及在试验完成后，如何使用LVDS通讯接口将实时监测数据和试验记录的数据发送到地面设备以分析和处理。 本文最后对固态存储器进行了功能测试和性能验证，并对试验结果进行分析和处理。同时，根据高可靠性的要求，提出了灌封和缓冲防护、环境应力筛选试验等保障措施。系统测试结果表明，固态存储器性能良好、可靠性高，并且完全符合任务设计要求。
[Abstract]:As an important part of the measurement and control system, solid state memory plays an irreplaceable role in the measurement and control system. It is the main way to obtain the flight status information of the aircraft and evaluate the performance of the aircraft system. Fault analysis and design and production improvement provide reliable test basis. The solid state memory designed and implemented in this paper completes the acquisition of analog signals and the reception of digital quantities, and stores the received data. After the experiment is completed, the solid state memory can be hard-recovered and the data stored in the memory can be read out for later analysis and processing. According to the design idea of modularization and high reliability, combined with the task requirement and performance index of solid-state memory, this paper puts forward the general design principle and design scheme of solid-state memory based on biplane technology. The main works are as follows: (1) taking FPGA as the control core, the acquisition of six analog signals and the reception of two PCM streams are completed, and the collected analog quantity and the received digital quantity are recoded. And reencode the data for mixed framing. (2) this paper introduces the timing of block erasure using biplane technique, page programming of mixed framing data and reading back data in time, and verifies the application of biplane technology in solid state memory. (3) this paper introduces the real-time monitoring in the experiment and how to use the LVDS communication interface to transmit the real-time monitoring data and the recorded data to the ground equipment for analysis and processing after the test is completed. Finally, the function test and performance verification of solid state memory are carried out, and the experimental results are analyzed and processed. At the same time, according to the requirement of high reliability, the safeguard measures such as filling and buffer protection, environmental stress screening test and so on are put forward. The system test results show that the solid state memory has good performance, high reliability and meets the requirements of task design.
