摘要:
为满足高压信号检测,设计了基于电压/频率,频率/电压转换以及光纤隔离的高精度信号数据采集电路。使用ADVFC32实现电压/频率,频率/电压转换,设计了由HFBR-1521发送器和HFBR-2521接收器组成的光纤连接电路来传输频率信号。最后通过AD7714对转换后的模拟电压信号进行A/D转换。电路设计结构简洁、可靠性高,具有一定的工程实用价值。
Abstract:
In order to satisfy the demand of the measurement of the high voltage,a high-precision signal acquisition was designed based on V/F conversion, F/V conversion and fiber isolation.The V/F and F/V conversion circuit was finfished by use of ADVFC32. Fiber-optic connection circuit for frequency transmission was designed by the HFBR-1521 transmitter and HFBR-2521 receiver.Finally A/D conversion was executed by the AD7714 for the analog voltage signal converted. Hard-ware circuit was designed.System structure was simple, and reliable,had some practical value.
