基于LabVIEW的虛擬回聲測深儀研究
[Abstract]:Aiming at the problems that the number of students is more, the number of experimental instruments is insufficient, the actual operation time of the students is small, the practical operation skills of the students are difficult to effectively improve, and the problem of the echo signal realization of the echo sounder in the laboratory is difficult, This paper designs and implements a virtual echo sounder for experimental teaching of marine instruments. On the basis of analyzing the function of prototype, the function of virtual echo sounder software is divided into three modules: system parameter module, function menu module and echo signal module. Based on LabVIEW as a software platform for developing virtual echo sounder, a virtual echo sounder which can simulate submarine echo signal and clutter signal in water is developed. Through the test and verification of the operation result, the virtual echo sounder realizes the important function of the prototype, and can simulate the underwater echo signal and the clutter signal to obtain better simulation effect. In the process of realizing the virtual echo sounder, the characteristics of the paper work include: based on the time of the computer operating system, it can be set independently without affecting the time adjustment function of the computer system time; Simulation and generation of submarine echo and clutter signal with real-time dynamic change. The realization of the virtual echo sounder can be used in the experimental teaching instead of the real echo sounder, so that the students can carry out operation training by a hand machine, solve the problem of insufficient number of real equipment sets of the echo sounder in the laboratory at lower economic cost, At the same time, the generation of the echo signal with dynamic change is also realized.
