Research On Simulation System For Floating People Beidou Control

Our country is a maritime country, which is also affected by marine disasters. Ourmarine disasters caused direct economic losses of￥500,000,000each year includingthe death of about500people. In order to take effective defence measures, this paperproposes a drifting trajectory simulation man overboard in the salvage plan, the purposeof the program is developed to simulate drifting buoy as the carrier, C8051F021MCUas the core, and through the acquisition of temperature data and longitude and latitudelocation track, and using the beidou satellite as the data transmission medium of beidoudrift control system.Simulate drifting beidou control system introduced in this paper, divided into dataacquisition system, power supply system, communication system, and the body, such asfour parts. In the design of data acquisition system, from system to system job requiresthe overall power consumption is low, so using C8051F021MCU as the core is a bestchoice. It has flexible clock hardware, the system can be easily between efficient modeof operation and low power consumption mode transformation, intelligent powermanagement mode can work in normal and standby switch freely, thus reducing theenergy loss of the whole system; When the working frequency is less than10kHz,clock lost detector (MCD) can trigger a system reset, ensure the safety of the system isreliable. Power supply system need to satisfy the high capacity, stable performance,small size and other characteristics, so choose the high capacity lithium battery, thebattery has the advantage of high capacity and power curve is smooth, there will be noelectricity throbbing. Communication system based on beidou data transmission modulewith GPS positioning module control system, high integration, low power consumption,the system is very suitable for large-scale application of system requirements. As theload simulation, using engineering plastics, on the whole sealing and corrosionresistance to seawater can meet strict standards.Drifting experimental results show the correctness of the design and structure,simulate drifting overall system stability, function complete and reliable data. At thesame time analyzes the whole experiment process, need perfect and summarizes the matters needing attention are put forward. Finally the system model is completed.
