摘要
介绍一种结构简单、精度高、成本低的高压设备绝缘在线监测系统的数据采集装置的软硬件设计方法和原理。该装置使用简单可靠的硬件高速锁相环电路,控制6通道Σ-ΔAD转换器实现同步整周期采样和跟踪滤波,实现对相互关联的6路信号进行同步数据采集和数据分析,并将设备绝缘状态传送到上位机,为上位机提供设备绝缘监测的原始分析数据。
The method and principle of hardware and software designing for a kind of data collecting apparatus with simple structure, high precision and low cost of on-line insulation monitoring systems for high voltage equipments in substations is presented in this paper. The designing principle is that a simple and reliable hardware phase-locked loop circuit with high speed is used to control 6 channel Σ-△AD converter, to realize the function of synchronous, full period collection and tracing filter, to collect synchronously and analyze the data of the 6 correlative paths of signals. Meanwhile, the states of the equipments are sent to the upper PC to provide the original insulation monitoring data.
