本文提出了多路模拟数据采集系统的一种新的结构型式——多总线并行输入结构。这种结构能大幅度提高数据采集速率,对高速单次瞬态信号有较强的捕捉能力。在每通道最高速率和通道数方面有较好的扩展性能。在采用转换时间为15μs 的 A/D 芯片时。每一模拟通道的采集速率最高可达50kHz。若采用更快的 A/D 芯片,采集速率还可以进一步提高。 This paper presents a new multi-channel analog data acquisition system structure - multi-bus parallel input structure. This structure can greatly improve the data acquisition rate, high-speed single transient signal has a strong capture capability. In the highest rate per channel and the number of channels have better scalability. In the use of conversion time of 15μs A / D chip. The acquisition rate for each analog channel can be up to 50kHz. If the faster A / D chip, acquisition rate can be further improved.
