摘要
本文介绍了一种基于PCI-1712数据采集卡的声信号高速采集系统。通过硬件电路对传声器拾取的微弱信号进行放大、滤波,并借助PCI-1712卡作为硬件采集平台,采用C++高级语言在C++ Builder编程环境中对采集卡进行驱动和控制,实现了声信号的高速采集、传输和存储。该系统可广泛应用于多种高速数据采集领域,具有良好的通用性和可扩展性。
A data acquisition system of acoustic signal with high speed based on PCI-1712 Card is introduced in this paper. The circuit which amplifies and filters the output signal of microphones is designed, and Advantech PCI-1712 is used as the hardware platform of the system. The programs using C＋＋ language in C＋＋ Builder programming environment control and drive the acquisition board, which makes acoustic signal high speed data acquisition, data transfer and storage. This system has good generality and expansibility which can be widely applied in various high-speed data acquisition field.
