基于Flash的高速數(shù)據(jù)記錄裝置關(guān)鍵技術(shù)研究
[Abstract]:Data recording equipment has been widely used in a variety of industries, including aerospace, radar, communications, industry and health care. Due to the maturity of radar research and development, more parameters such as the shape, position and moving state of the target must be recorded for the accurate location of the target object. In order to obtain accurate and high-definition target image, radar echo signal will produce a large amount of data in a relatively short time. The development of large capacity data recorder has become an important task. With the development of semiconductor technology, Flash has become the preferred storage medium for recorder with excellent performance. This paper presents a design of high-speed data recorder based on Flash. The equipment has the characteristics of small volume, light weight and high impact overload, and can adapt to the harsh conditions of high altitude test environment. First of all, this paper introduces the semiconductor storage medium, investigates the development of solid state recorder at home and abroad, gives the various indexes of the recorder in the task book, and expounds the composition module and working principle of the recorder. The principle block diagram and function analysis of interface module and storage module are introduced in detail. Secondly, the key problems in the research process, such as the high-speed storage implementation of Flash, the internal two-stage buffer and reliability design of FPGA, are analyzed and explained in detail. Thirdly, according to several representative problems in the debugging process, the concrete ideas and solutions are given, which is helpful to understand the whole design process more deeply. The closed loop test system, which is composed of upper computer, tester, recorder and cable network, has completed the function test and verification of the recorder. Finally, the research content of this paper is summarized, and the future prospect work is made in view of the problems and shortcomings in the design. At present, the product of the data recorder has been delivered, which can be used successfully to record the high-speed video echo and image telemetry data generated by radar during flight test, and to realize the hard recovery of the recorder after the aircraft lands. The recorded flight parameters can be accurately obtained.
