该文介绍了一种用于监测电动执行机构实时性能的监控与数据采集(SCADA)软件系统的设计方法，该方法同样可被应用于生物信号处理领域．系统中应用了Windows的动态链接库与多媒体定时器技术，从而实现了系统的模块化并提高了实时性．经现场运行调试，该系统的实时性能够得到保障，且通信是稳定可靠的．-this paper for a body monitoring the implementation of real-time electrical properties of the Supervisory Control and Data Acquisition (SCADA) Software system design, the method can also be used in biological signal processing areas. System Application Windows dynamic link library and multimedia timer technology, thus achieving the modularization of the system and improve the real-time. After running tests, the system's real-time can be protected, and communication is stable and reliable.
