摘　　要：针对实时多传感器数据采集系统因系统处理的数据量大、实时性强,基于硬盘数据库的系统开发难以胜任实时性、快速性要求的问题,通过对嵌入式内存数据库ExtremeDB的应用研究,解决实时多传感器数据采集系统在海量数据接收的情况下实现处理数据的实时性。在ExtremeDB的应用中,详细说明了构建内存数据库的方法,并通过模式编译器生成数据库API,在与硬盘数据库性能对比中,证明ExtremeDB内存数据库在各方面都具有较大优势。用ExtremeDB开发实时数据采集系统可有效地缩短开发周期,对提高系统的实时性和可靠性,具有一定的借鉴和指导意义。The use of the multisensor system of real-time date acquisition is becoming more and more widespread in industrial control,aerospace,voyage,medical treatment and so on.As real-time date acquisition system must transact large,real-time date,development system based on HD date-base can hardly meet demands of real-time and high speed.When extremeDB database was used in multisensor system of real time date acquisition,the real-time question could be solved under the instance of receiving large date.The method of designing extremeDB database was developed in application of extremeDB.Furthermore,database API was generated by the schema compiler.Comparison showed that the extremeDB database has more predominance than HD database in every aspect.The performances verified that the design was effective.
