摘要
详细介绍了用于大型多点激振测试设备上的数据采集板的结构，并给出了该数据采集板的设计要求，它们包括：Ａ／Ｄ转换、数据缓存、触发、多板并行工作和可任意编程的模拟输入通道的地址切换电路等。它可广泛应用于多种信号分析、振动测试等场合。文中最后还给出了它在大型纺织机械模态试验中的应用实例。
resents the structure of data acquisition board used in 256 channels' Multi-point Exciting and Measurement system in detail. It also describes the main points of design. It includes AD conversion, data buffer memory, trigger, multi-boards working synchronously and programmable acquiring sequences. This board can be widely used in signal analysis and vibration measurement fields. At last the authors give its practical examples.
