摘　　要：快速存贮方法为航天测控类应用项目而设计,提出了实时系统下数据文件依文本方式存储的策略,使用Rad Studio开发工具展示了几种文本文件存贮方法,分别使用PASCAL和C++语言编写了相关函数,写出一个面向各种存贮要求的执行线程,设计了文件名产生的函数方法与存贮表现方式。设计为线程形式的存储机制适用于各种相关应用存贮项目。线程等待2种通知,一种为与实时系统有关的windows内核事件对象,一种为与界面相关的逻辑变量,只有2种通知全到达时才真正存储,经试验该种存储方法在10 ms的级别内完全可以准确无误的依照文本方式存储数据。The rapid file storage method is designed for aerospace measurement and control project. This paper puts forward the storage strategies of data files used as text files in realtime system. Several text file storage method are presented using Rad Studio. PASCAL and C＋＋ languages are respectively used to write autorcorrelation fimction, and an execution thread is designed orienting to various storage requirements. The function method of producing file name and the storage manifestation mode are designed. The storage mechanism of thread mode is designed to be suitable to various relative application storage projects. The thread waits for two kinds of notice, one is real-time system Windows kernel event object, and another is logic variables rdated to interface. When all these two notices arrive, the storage is implemented authentically. The experimental results show that this storage method can exactly store the data in text mode in 10ms.
