Design Of Unmanned Ship Movement System Under Remote Wetland Monitoring System Based On Zigbee

As an important ecosystem on the earth, Wetland has the very powerful functions ofmoisture regulating, purifying water quality, species production and improve the localclimate. In recent years, the wetland ecosystem has been polluted and degradated because ofhuman factors. To protect the wetland environment need to master the wetland area ofhydrological information at any time, the traditional way of gathering information cycle islong, the coverage is limited. Under the condition of the zigbee network is adopted, the use ofunmanned ship carrying way of zigbee node information collection.This designed by unmanned ship motion system of two modes: joystick control modeand the guide map. The operation of the joystick control mode, through to the rocker tocontrol speed and direction of hull; Map guide mode, through setting the finish on the mapfor the unmanned ship, combining with the location information of unmanned ship, guide theunmanned ship to the destination. Unmanned ship in driving process, once found to haveobstacles, can avoid obstacles, and then continue to the target.The unmanned ship movement system is based on the Zigbee network development,used ATmega128as main control chip, and produce two lines of PWM wave to control the dcmotor and servo of the unmanned ship; By adopting three ultrasonic module ranging in theform of obstacles in front of the judge, in order to control the hull to bypass obstacles; WithGPS module for location information, and thus can be displayed on the map; Through theupper computer program written by myself, to send control data to unmanned ship andcontrol of unmanned ship to the desired location.
