舰船物理场水池测量系统设计
|
摘要
为了使学生掌握舰船物理场的基本特征,设计了舰船物理场水池测量系统。采用MSP430单片机系统控制系统工作状态,FPGA控制AD采样器和FLASH数据储存器进行数据采集和存储,RS232数据通信接口和无线电台进行数据传输。借助该实验系统,学生在水池实验室条件下就可以观测到舰船通过时的声场、磁场和水压场信号波形,并分析信号的时域和频域特征,深化理解课程中关于舰船物理场的知识。
In order to help students to master the basic characteristics of the ship physical field,apool measuring system for the ship's physical field is designed.The MSP430 SCM system is used to control the working state of the system.Data acquisition and storage are carried out by the AD sampler and FLASH data memory which are controlled by FPGA.Data transmission is implemented by the RS232 data communication interface and radio station.With the help of this experiment system,students can observe the signal waveform of the sound field,magnetic field and water pressure field when the ship passes under the condition of the pool laboratory,analyze the characteristics of the time and frequency domains of the signal,and further understand the theoretical knowledge about ship's physical field in course learning.
