Problems solved by technology

For example, the standardized products of the active power monitoring system of MTU and MAN B&W only realize the centralized control room and cab control functions in the three-level control. The manual control scattered around the main engine, gear box, and controllable pitch propeller does not have functions such as centralized control or automatic synchronous paralleling, load distribution, and automatic load limitation. However, the imported equipment is highly standardized and difficult to modify, requiring redesign or large-scale modification unrealistic design

Embodiment 1

[0029] This embodiment provides a machine-side centralized control device for the main propulsion device of a ship, including a host control unit, a host control panel 1, a gearbox 11 control unit, a gearbox 11 control panel 2, a propeller shaft control unit, a propeller shaft control panel 3, Controlled pitch propeller 12 backup control unit, controllable pitch propeller 12 backup control panel 4, main machine tachometer 5, controllable pitch propeller 12 tachometer 6, shaft tachometer 7, coaxial main engine tachometer 8, the host control unit is used For control authority conversion and host speed control, the host control panel 1 is connected to the host control unit to realize the interaction between the user and the host control unit, and the gear box 11 control unit is used to realize the connection between the local host and the coaxial host. between the automatic load distribution; the gearbox 11 control panel 2 is used to realize the interaction between the user and th...

Embodiment 2

[0031] This embodiment provides a machine-side centralized control method for a main propulsion device of a ship, which includes the following steps:

[0032] Step 1. Control the machine-side centralized control device through the host control panel 1 to obtain local-level remote control authority; the control authority level of the machine-side centralized control device is higher than that of the central control room control station and the cab control station.

[0033] Step 2. Control the main machine (No. 1 machine 9) to connect to the row through the control panel 1 of the main machine. The speed of the main machine of this machine is automatically adjusted to the speed of the first machine to connect to the row and automatically connect to the row; specifically: press No. 1 machine 9 to connect to the row. button, the speed of No. 1 machine 9 is automatically adjusted to the speed of the first machine to connect to the row and automatically connect to the row. After conne...

Abstract

The invention provides a centralized control device beside ship main propulsion device and control method. The control method comprises the following steps: step 1, controlling the local centralized control device to obtain a local-level remote control authority through a host control panel; step 2, controlling a local host to be connected through the host control panel, automatically adjusting the rotating speed of the local host to a first host connecting rotating speed, and automatically connecting; and step 3, when double-engine parallel operation is needed, controlling a coaxial main engine to be connected and arranged by the host control panel, automatically adjusting the rotating speed of the coaxial main engine to the actual rotating speed of the main engine, then carrying out automatic connection and arrangement, and completing automatic synchronous parallel operation. The centralized automatic control function and state display of the local main propulsion device of the engine room are realized, the emergency control function is considered, the operation is simple and convenient, the automation degree of local control of the engine room and the operation efficiency of the main propulsion device under the emergency working condition are improved, the ship vitality is improved, and the device is especially suitable for an automatic control system of a ship main propulsion device.

Description

technical field [0001] The invention relates to the technical field of monitoring of a ship's main propulsion device, in particular to a machine-side centralized control device and a control method for a ship's main propulsion device. Background technique [0002] Diesel-diesel combined power unit is a combined power unit composed of two or more diesel engines driving a propeller through transmission and shafting. By adopting the "single engine / shaft" or "dual engine / shaft" operation mode, it can meet the performance requirements of ships in different operating conditions, make the diesel engine run in a higher load area, and have good economy and vitality. At present, the monitoring system configured for this type of power plant in China is mainly "Type I control" in GJB4000-2000: that is, the equipment and systems of the main power plant are equipped with control, monitoring, alarm and safety systems, and are remotely controlled in the cab and electromechanical centralized...
