| 中文摘要 | 本文介绍了应用先进的DSP平台技术研制新型声管测量系统的方案设计和具体实现。全篇可以分成以下几个部分：．声管测量系统的背景知识介绍．DSP平台技术简介．系统方案设计．算法的详细描述声管是水声材料测量的重要设备，传统的声管测量设备繁多，使用起来相当复杂，而且效率低下，DSP平台技术的出现为解决这一问题提供了可能。DSP信号处理平台集D／A转换、A／D采样、数字信号处理于一身，设备精悍，性能稳定可靠，应用范围非常广，非常适合于声管这样以传感器为测量装置带有复杂计算的测量系统。应用本文所阐述的设计方案制成的新型声管测量系统具有操作简便直观、高效率、高精确度的特点，而且即将投入到实际应用中。在测量方法上，声管自动测量系统选择了经典的脉冲频谱法和近期研究成熟的传递函数法，并对工作频率及各项参数进行了精心的设计。另外在具体算法实现时还有许多技术细节问题，这在本文中都做了详细介绍。 |
| 英文摘要 | This paper introduces the design and implementation of new Water-filled Tube measurement system base on DSP platform. The paper is composed of four sections: ·Background introduction of Water-filled Tube measurement system. ·DSP platform ·Project Design ·The analytic design of the software Water-filled Tube is a important equipment on underwater acoustical materials measurement. The traditional method of Water-filled Tube measurement is very complex and inefficient, it need so many equipment. But these problems can be solved today for the new technique of DSP platform coming into being. DSP platform is integrated of A/D conversion, D/A conversion and digital signal processing, that is steady and wide used. DSP platform is very applicable on Water-filled Tube measurement, for which containing sensor equipment and complex calculate. The new automatic system implemented by the design of this paper is more handy and efficient, that will be put to use in study work soon. The automatic system adopt two measurement methods, one is classic sound pulse, the other is transfer function, which is discuss'maturely recently. Manyccoefiicient such as work frequency is designed carefully. There are many arithmeticJ details in this system, that are mention in this paper also. |
