Remote Control Fishing Boat Anchor Machine Visualization System Design

At present, ship mooring system is still operated manually, including throwing andtaking an anchor, and the crew’s experiences play an important role as someone has tomonitor the whole operating process on the spot. There are some dangers in such anoperation due to the primitive mode and the poor anchor warning ability. Ships are inpotential safety hazard. Especially in the typhoon weather, etc. And it is easy to happenanchoring operation safety accidents, cause the dragging anchor accident and shipcollision, collision and standing accident and so on. If using anchoring visual remotecontrol completes these operations, operators who needn’t stay at the ship or on-sitemonitoring process can finish the operation such as drop anchor or weigh anchoroperation safety problems improved significantly.This paper bases on medium and small fishing boat as the main object, analysesdrop anchor, weigh anchor of working principle and development present situation.Putting forward fishing ship anchor machine visualized feasible scheme of the remotecontrol system, through software programming, hardware design, production and testing,then finish equipment development tasks. The system includes main control module,detection module and wireless video transmission module. Main control module includesLCD liquid crystal display and its interface circuit with single-chip microcomputer, etc.Detection modules contains liquid crystal displays, windlass control drive, voltageregulator circuit design and its interface circuit with MCU, also including chain gearspeed reduction gear box, transformer and power supply unit, etc. Wireless datatransmission module is mainly composed of a transmitter, a receiver, CRT TV andcamera. Using the module can monitor on the main end windlass deceleration andpositive&negative live, also can observe chain yawing motion video to achieve shipanchor prediction. System working principle is: press starting button on the main controlmodule, main control module SCM sends PWM wave, detection of end receives thePWM wave, then drives windlass running. In the middle of drop anchor or weigh anchorprocess, if speeding up or slowing down button on the main control module, MCU can send duty radio of increasing or decreasing PWM wave. Pressing the main modulebutton, revering the main microcontroller will command signals wirelessly transmitted todetection module, detection module receives the command by H Bridge after four effecttube voltage polarity electric windlass steering.The prototype test results show that it can be in km outside the control of electricwindlass speed size and rotational direction, engineering operation can master the LCDmonitor at the master size of windlass speed and steering, windlass and the chain throughthe CRT display to yaw movement of live. It can adjust the turning of the windlass tosatisfy the small and medium-sized fishing boats anchoring operation requirements.Based on the safety of the ship control, this paper aims to explore the effective anchoragecontrol and information management method.
