摘要
在变电所微机监控系统中,为了使采样频率能够跟踪输入信号频率的变化,CPU必须清楚当前输入信号频率的变化情况。在分析了交流采样的基础上,提出了一种基于DSP2407的同步采样方法,给出了硬件实现方案,参数计算方法和软件实现流程。
CPU must read the current frequency change of input signal in order to track the frequency change of input signal by sampling frequency at the substation microcomputer monitoring system. By analyzing AC samples, a synchronous sampling method based on I）SP2407 is put forward, and the hardware implementation program, parameter calculation method and software implementation flow is given.
