The Research And Design For The Echosounder Of Underwater Synthetic Explored Robot

Since the late 1980s,the intelligent robot as one of our modem civilizatiOnshas very large process. Our country is a country that is surrounded by broad ocean,Therefore the underwater intelligent robot has a particular strategic position in thenational defence and national economy. This thesis is a section of research intoechosounder that is a partial of the underwater synthetic explored robot.The aim of thesis is to ensure the underwater intelligent explored robot belowwater are safety. Echosounder is fired on underwater intelligent explored robotand come into watCr. RealtAne feedback infOrmation of height gives maincomputer on the bank. Main computer leads the robot on based of infOrmation ofheight and avoids robot to get in water bottom.The first task in the thesis is to make acoustic model. account practicetransducer and other acoustic parameter' research and analyze arithInehc ofechOsotmder. research and analyze factors of influence system precision and mesafety.The second task in the thesis is to design hardware circuit. low noise. lowPOwer and high stability are followed while select chiP and design circuit.The last task in the thesis to program software according to system achievedtask, including DSP prograInIning. VHDL progranuning of EPLD' display andcontrol programming. Because DSP and EPLD is programmable in system.reliability and agility of system increases and uPgrade of system becomesconvenient. asynchronous series communication is adopted betWeen maincomputer and DSP. Visual C++6.0 is used in progranuning display and control ofmain computer.
