[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.
