Problems solved by technology

[0009] 1) Poor anti-vibration performance;
[0010] 2) High power consumption;
[0011] 3) The operating temperature range is relatively narrow
DRAM has a large single-chip capacity and a high access rate, but it needs to be refreshed regularly, data is lost when power is turned off, and compared with other chips, it consumes more power, etc.

Embodiment Construction

[0051] The high-speed and large-capacity solid-state electronic recorder of the present invention adopts a NandFlash chip as a storage medium. Its main technical indicators are as follows:

[0052] 1) Recording speed: ≥1GB / s (average rate);

[0053] 2) Storage capacity: ≥1TB (1024GB);

[0054] 3) Three working modes: record mode, playback mode, BIT mode;

[0055] 4) Four parallel input and output interfaces coexist with eight serial input and output interfaces (the default is serial interface); the rate of the parallel interface is 80MHz (each clock transmits 4 bytes of data); the rate of the serial interface is 2Gbps;

[0056] 5) Four storage channels, they can be dynamically configured, if configured as one channel, then the highest recording rate can reach 1GB / s; if configured as four channels, then they can work independently of each other, suitable for the coexistence of multiple sensors Condition;

[0057] 6) Control interface: RS485 interface / RS422 interface;

Abstract

The invention discloses a high-speed high-capacity solid electronic recorder and relates to a data recorder technology. A memory module of the high-speed high-capacity solid electronic recorder takes a NandFlash chip as a memory medium; the memory module combines a NandFlash chip array in a combined way of parallel extension and serial extension, improves the memory speed through the parallel extension and improves the memory capacity through the serial extension; a field programmable gate array (FPGA) manages the NandFlash chip array; a data distributing module receives and caches external input data; when the memory module is in an idle state, the data is packaged and transmitted to the memory module; a control module is controlled by an upper computer and controls the data distributingmodule and the memory module to realize all the functions of the recorder; and a bottom plate module makes the modules electrically and mechanically connected and is used for transmitting electric power, commands and data. The high-speed high-capacity solid electronic recorder is reasonable in structure, so that the integral performance of the recorder is greatly improved; the recording speed reaches the GB / s level; and the capacity reaches the TB level.

Description

technical field [0001] The invention relates to the technical field of data recorders, in particular to raw data recorders for synthetic aperture radar (SAR), infrared and visible light CCD cameras, hyperspectral instruments and the like. Background technique [0002] The data logger is an important part of the synthetic aperture radar (Synthetic Aperture Radar, SAR) system. It records the original data and auxiliary data of SAR (flight parameters, SAR status, control and other information). When the SAR stops working, the data of the data recorder will be played back to the general-purpose computer so that the ground imaging processing center can perform precise imaging processing on them and obtain high-quality SAR images. In addition to being applied to SAR systems, data loggers are also widely used in raw data recording of infrared and visible light CCD cameras, hyperspectrometers, high-energy physics and automatic testing equipment, playing a very important role.
