在进行无线电信号监测软件的设计时,为了提高实时响应性能,挖掘仪器的最好性能, 本文给出了一种利用双线程的设计方法。同时,为了增强了系统的对硬件接口的良好的可适应性及可扩充性,对该系统的底层线程采用C++的类进行了设计改进。使得系统的整体性能得到了显著的提高。 关键词:GPIB 总线;短波监测;接收机;线程 Abstract: During the software development of shortwave monitoring system, to acquire an optimal real-time performance is one of the aims that such software aims at; in this paper, the author presents a method to obtain this aim under a dual-thread mechanism. At the same time, to extend the flexibility considering different kinds of interface, an interface class has been designed with C++ language, which gives the whole system a more favorable performance as well.
