Research And Design Of Marine Engine Remote Control System

As the ship automation levels gradually increase, on main engine remote control system requirements getting higher and higher degree of automation, conventional pneumatic control of main engine remote control system, electrical control of main engine remote control system is unable to meet the demand for development of marine automation. At present, the domestic higher degree of automation of main engine remote control system is mainly controlled by PLC and microcomputer control. Both types of products there are high costs, volume and other factors, however in some require the use of low-cost, compact environment, PLC control microcomputer control of main engine remote control system of main engine remote control system and its price competitiveness and volume of obvious disadvantages.By studying the domestic current situation of main engine remote control, the designers made based on C8051F040design of main engine remote control system based on single chip, main engine remote control system remote control unit is divided into cab (including host controller), the control room next to the remote control unit, control box (including security control unit), pneumatic tank next to the machine, host, tail shaft speed sensor speed sensor, six parts. C8051F040is used as the primary controller CPU, reversing combination electrical control hosts, start, acceleration and deceleration. Control master switch is used as analog processing, and then via the a/d converter converts digital input to the CPU, CPU on digital measure test switch state.The programme was respectively design has simulation volume entered, and switch volume output, and simulation volume output, and communications, and host security monitoring and the people machine Exchange, hardware module, which simulation volume entered module for collection all unit on host of manipulation information; output module for control host started, and reversing, action perform; simulation volume output was for output current, control electrical proportion valve opened of, adjustment host plus deceleration; communications module implementation unit Zhijian communications; monitoring security module main completed host run state of monitoring, And according to status output alarm information; human-machine exchange of parameter setting and status query module completed.The design and implementation of miniaturization and modularization design of main engine remote control system, solve the problem of the high cost of main engine remote control system.
