The Digital Platform Design Of Synchronous Beacon

Synchronous beacon is an important measuring equipment of target positioning. We can get the positioning information through signal processing,which is emitted by the beacon equipped on the underwater objectives.In this thesis, the study is a hardware and software design and implementation of digital platform of synchronous beacon.. System hardware design includes:control unit design, the synchronization signal unit design, memory cell design and power design. Software design mainly for TI's MSP430 ultra-low power microcontroller and Altera, Cyclone series of FPGA programming.Salient features of this system is to achieve a long storage of pressure data and a variety of signal patterns can be configured to function. Three signal modes are:calibration mode, dynamic mode and static mode. Calibration mode used for system installation error calibration; dynamic operating modes for the underwater target positioning within 300m; static mode used to achieve the dual targets positioning.After field testing, the system can achieve the design requirements.
