摘要 研究多通道测试系统的工作原理,并设计了一种多通道水声自动测试系统。多通道测试系统需工作在宽频段范围,由于受到换能器和电子设备的频段限制,故将整个测试系统分为中频和高频2套独立系统分别进行设计。其中,中频多通道测试系统能够对400Hz^100kHz频段的声学装置进行测量,高频测试系统的工作频段为100~500kHz。该多通道水声自动测试系统采用了通用仪器与板卡相结合的思路进行设计,系统能够提供可视化应用和管理软件,通过合理分配测量时间可完成高效测量多通道指向性等指标,并可实现多种水声参数的自动化测量,极大地提高了测量自动化程度。 This paper discusses the working principle of the multichannel test system,and designs a multichannel underwater acoustics automatic test system.The multichannel test system needs to work in a wide frequency boundary,due to the limitation of the frequency of the transducer and electronics,the whole test system is divided into two single system:middle-frequency and high-frequency.Middle-frequency multichannel test system can measure the acoustics device which frequency is from 400 Hz to 100 kHz,and high-frequency multichannel test system works at 10 kHz to 500 kHz.This multichannel underwater acoustics test system conbines the general instrumentation and the board to design,so it can provide a software of visual application and management,it distributes measuring time to finish the high-efficiency measure multichannel directivity,and realize many kinds of underwater acoustics parameters ‘ automatic measurement,so it can highly average up the automation.
