A Study On Remote Control Underwater Basing On Low Power Signal Chip

With the increasing of ocean exploitation, underwater acoustic (UWA) communications have received much attention and being one of the most challenging subjects in the research of underwater acoustics.With the development of communication and digital signal processing ,remote control have entered into the appliing ages. Underwater,digital remote control system have developed rapidly along with the needing of ocean exploitation and weapon underwater. It will have the capacious using foreground in underwater communication remote measuring controlling of underwater aircraft. To a underwater remote control system power is a very important parameter. Especially for the underwater equipment which needed put in water for a long time such as fish torpedo,measuring setting.Designing low power acoustic digital remote control system Is selected as major reasher issue. Finished arithmetric simulation and experimentation proof in the pivotal technology . the main content in this paper are as follows:1. Using the shift frequency code as the acoustic remote control coding.2. Using the self adaptive filter as the decoding filter.the filter have the pectination frequency response. It can identify many code parallel in time . The simulation identified that it can minimize the influence on decoding automatically.3. Hardware and software are built by author basing on the Msp430f1611 singlechip. Authorized the incepting and decoding programming basing on the singlechip. Processing the examination in the laboratory on the remote control system.
