摘要
设计了一款数字式高速全隔离的信号采集电路。以V/F、F/V变换实现了模拟信号的传输,以红外通信来实现采集板和处理板之间的通信,以高速A/D实现了对模拟信号的采集。经测试,达到了预期的设计效果,具有较高的实用价值。
This passage design a signal acquisition circuit of digital high speed and full isolation. By using the V/F, F/V transformation to realize the transmission of analog signals, and using the infrared communication to realize the acquisition and processing board between class communications, using the high-speed A/D to realize implementation of the analog signal acquisition.
