摘　　要：针对遥测系统数据记录装置中数据传输速率与存储速率不匹配的问题,提出Flash的并行存储方案,采用交替双平面的编程方式可以使得存储器的存储速率达到单片Flash最高存储速率的2倍,即60 MB/s;对控制单元FPGA内部双端口RAM的逻辑设计进行改进,解决了数据存储异常的现象。在数据回收方面,提出了多备份的设计思想和备用读数接口的设计方案,已在工程应用中得到成功实践,验证了该数据记录装置的可靠性。For the data recording device of telemetry system, it＇s a problem that the transmission rate of data can not match the rate of storage. The paper puts forward the parallel storage scheme of Flash. With the interleave two-plane page program mode, the storage rate reaches double of the highest speed of monolithic Flash, namely 60 MB/s. The design of logic control of dual port RAM is improved to solve the problem of the data storage anomaly. In the aspect of data recovery, this paper puts for- ward the idea of double design and spare reading interface, which has been successful practiced in engineering application,and veri- fied the reliability of the data recording device.
