Main Engine Remote Control System Overview

The so-called Remote Control of the Main Engine refers to manipulate people away from the machines engine control room centralized control platform or bridge control platform via the internal electrical automatic control system to manipulate the main engines way. Main engine during operation has high heat, noise, and manipulate large labor intensity. There was also a mechanical remote control, not very far away from the engine. Since the 1990s, with the rapid development of computer technology, the construction of new large vessels are all used the advanced technology to manipulate the remote control of the main engine.

Maneuver the main engine is to send commands to the main engine by the bridge through telegraph, the duty engineer machine next to the engine to answer the bell instruction, then the engine into command position joystick. This requires that the engine side must be manned by a human operator situation master, it is inevitable there will be a mistake occurs, which requires the engineer must be familiar with the operation of the performance of the host and have skills of skilled operators. After the ship using a host of advanced remote control device, just one driver (non-engineer) in the cab can easily start the engine, stop, forward, backward, adjust a variety of speed. Greatly reducing the crews labor intensity and improve the working conditions of the crew, to avoid human error handling.

The main functions of the Remote Control：

1) The commutation function: When the car clock command and the actual position of the camshaft host does not match, you must first automatic commutation, for sending to allow completion of the start signal. Host commutation refers to the position of the camshaft converted from its original operating state to another operating state position, commutation and brake: parking under a state of commutation. When the handle is pulled toward the positive from the parking position or reverse drive position, the host must stop the oil, valve action, for work to the device, the air distributor, fuel, exhaust camshaft converted from their original location to telegraph instructions position, and then proceeds to the normal startup logic. b. commutation in operation.

Remote Control commutation function is to ensure that from one shift to another shift operation is accurate. When the handle is pulled to the opposite position from the original operating position, the change will occur to the operation, first stop the oil system of the machine instruction, so that the host speed down until the speed drops commutation speed (about 30 to 20 rev / min) start reversing this process takes about 2 to 3 seconds, enter the start signal is given to start the program after the completion of the commutation delay. Change the steering backwards and telegraph instruction remains consistent, the loop will continue to stop oil. Here to introduce the concept of braking. First, braking the ships master brake itself, the second is the host reversing the propeller thrust negative, no thrust, but the inertia of the ship as well, the negative thrust of the ship quickly slow down, stop and reverse.

Main engine brake in two ways: one is the dynamic braking, also known as decompression brake, which is after the completion of commutation, at this time does not match the steering camshaft position when the air start valve cylinder dispenser it opens in the compression stroke of the piston, so put it in the other valve is discharged from the start of air suction stroke, the main starting valve bleed air pressure within the cylinder when the piston down subsequent expansion stroke in a negative pressure state, when the piston down

Main Engine Remote Control System Overview

船舶主机遥控系统概述

The so-called Remote Control of the Main Engine refers to manipulate people away from the machines engine control room centralized control platform or bridge control platform via the internal electrical automatic control system to manipulate the main engines way. Main engine during operation has high heat, noise, and manipulate large labor intensity. There was also a mechanical remote control, not very far away from the engine. Since the 1990s, with the rapid development of computer technology, the construction of new large vessels are all used the advanced technology to manipulate the remote control of the main engine.

船舶主机遥控指的是主机的操纵人员在远离机器的机舱集控室里的集控台上或者驾驶室内的驾控台上利用电气自动控制系统来操纵主机的方法。主机在运转过程中有很高的热量，噪音，操纵人员劳动强度也很大。以前也有机械式的主机遥控，离主机的距离不是很远。从20世纪九十年代起，随着计算机技术的迅速发展，新建造的大型船舶全都采用了先进的主机遥控技术来操纵主机。

Maneuver the main engine is to send commands to the main engine by the bridge through telegraph, the duty engineer machine next to the engine to answer the bell instruction, then the engine into command position joystick. This requires that the engine side must be manned by a human operator situation master, it is inevitable there will be a mistake occurs, which requires the engineer must be familiar with the operation of the performance of the host and have skills of skilled operators. After the ship using a host of advanced remote control device, just one driver (non-engineer) in the cab can easily start the engine, stop, forward, backward, adjust a variety of speed. Greatly reducing the crews labor intensity and improve the working conditions of the crew, to avoid human error handling.

主机的操纵是驾驶室利用车钟向在机舱的主机发送指令，机旁的值班轮机员应答了车钟指令后，然后将主机的操纵手柄推到指令位置。这就要求主机旁边一定要值班人员，通过人工来操作主机，不可避免的会发生操作失误的情况，这就要求操作的轮机员一定要熟悉主机的性能和拥有熟练的操作技能。船舶使用了先进的主机遥控装置后，只要驾驶员一个人（非轮机员） 在驾驶室内即可轻松完成主机的启动，停止，前进，后退，调整各种转速。非常大的减轻了船员的劳动强度，提高了船员的工作条件，避免了人为的失误操纵。

Maneuvering position and convert the remote control system. Usually set up three control Location: beside the cab, engine control room, machine, these three positions can be converted to each other. Machine next to manipulate, also known as the emergency operation, when some failure control system can be manipulated to position the machine next operation. Machine next to the control room and the host manipulation conversion is performed by a switching valve machine next to the execution, will control air pipe connected to the line control or control room next to the machine, but also convert handwheel operation, so tune speed with the throttle shaft disengaged host (the machine next to) or engaging (control room). Conversion control room with a control cab position, is set by the center console switch to complete. Driving control console and the stage are manipulated by the host commands to manipulate the host electrical solenoid valve in the tank to start, stop, forward, backward, four solenoid valves, control is performed to drive air through the main starting air. Between the cab and the control room shift control position to another answering recognized. It must be emphasized: Three maneuvering position conversion function to ensure that the host can only be operated in one location.

主机遥控系统的操纵位置和转换。一般来说有三个控制位置：驾驶室、集控室、机旁，这三个位置可以互相转换。机旁操纵也称为应急操纵，当控制系统有某些故障时，可将操纵位置转到机旁操作。机旁和集控室对主机的操纵转换是利用机旁的一个转换阀来完成的，即通过将控制空气接通机旁的管路或者集控室控制的管路，同时还要操作转换手轮，使调速器与主机的油门轴脱开（机旁）或者啮合（集控室）。集控室与驾驶室控制位置的转换，是通过集控台上的转换开关来完成的。集控台和驾控台上操纵主机都是由电气的指令来操纵主机电磁阀箱中的启动、停止、前进、后退，四个电磁阀，利用控制空气带动主起动空气来完成的。驾驶室与集控室之间操纵位置的转换要互相同意认可。必须明确的是：三个操纵位置的转换功能要确保只能在一个位置上操纵主机。

Remote control system is based on the characteristics of the host and operational requirements designed to host different models, ship building owner selection habits, the specific configuration of the remote control system there is a difference. Japan N ABCOs M-800Ⅱ type remote control system, the control program is simple, practical, reasonable and perfect control, to a certain extent reflects the latest developments in the host computer remote control system This system is a complex and comprehensive control system.; in control theory, it has open and closed loop control; there are feedback and feedforward control; as well as the timing and control logic below is M-800Ⅱ type remote control system block diagram of the system configuration

主机遥控系统是依据主机的特点及操作要求设计的，主机型号不同，船东船舶建造的选型习惯，遥控系统的具体配置是有差别的。日本N ABCO 公司的M-800Ⅱ 型主机遥控系统, 控制程序简单、实用, 控制功能合理完善, 在一定程度上反映了主机微机遥控系统的最新发展动向. 该系统是一个复杂的综合性控制系统; 在控制理论方面, 它有开环和闭环控制; 也有反馈和前馈控制; 同时还有时序和逻辑控制.下面是 M-800Ⅱ型主机遥控系统系统配置方框图。
