Research On Display And Control Software Of Shallow Multi-beam Bathymeter

Compared with single-beam bathymeter, the multi-beam swath bathymeter is a kind of seafloor mapping equipment with higher capabilities in efficiency, accuracy and resolution; it is fit for measuring the wide area especially. Now the greater technique improvements are required for some new application fields, for example, the design of miniaturization of the bathymeter for adlittoral area is being one of the main research directions.In this paper, a set of display and control software in real time for one adlittoral multi-beam bathymeter is studied. The system of software is based on Windows operation system, has the capabilities of oceanic depth measurement, navigation and orientation; and can communicate using RS-232 and USB ports.In this thesis, the system structure of software and the working principle of adlittoral multi-beam bathymeter are analyzed firstly; the technique of display and control in real time is studied, and then the according software is programmed; at the same time the paper realized the data communication using RS-232 port. As the main work, the study of USB device driver also is done successfully: the frame of WDM driver is constructed by DriverWorks, and the driver of USB device of PDIUSBD12 made by PHILIPS Corporation is accomplished. Designed in VC++6.0 computer language, the set of software has the better characters such as friendlier man-machine interface, operation in easier, more expansibility and so on. It can display much useful information including depth data, orientation and the working status of equipment, etc. In a certain extent, this work is valuable and lays the foundation for future development of adlittoral multi-beam bathymeter.
