本文介绍全数字化遥测系统的微机采集与遥测软件的设计方法。根据数字化遥测的特点,分析一个主、从双微机的采集系统,提出程序设计的要求,作出一套可供数据处理使用的数学模型。考虑到遥测速变信号中的功率谱、相关函数较为复杂,为此,给出了它们的程序设计的步骤。最后讨论应用八位微机时应注意的几个问题。
This article introduces the design method of microcomputer acquisition and telemetry software for all-digital telemetry system. According to the characteristics of digital telemetry, this paper analyzes a master and slave dual-computer acquisition system, puts forward the requirements of programming and makes a mathematical model for data processing. Considering the power spectrum in the telemetry fast changing signal, the correlation functions are more complicated. Therefore, the procedure of their programming is given. Finally, discuss the application of eight microcomputer should pay attention to several issues.
