Embodiment Construction

[0043] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0044] Such as figure 1 As shown, the DP-3 dynamic positioning system of the present invention is composed of a control layer and an equipment layer, and each layer will be described separately below.

[0045]The control layer consists of three consoles (console A1, console B2 and backup console 3) and a dual redundant network structure (network 4 and network 5). Each console consists of a display terminal, a control panel and a switch. Console A1 and console B2 are arranged at the same location, and the spare console 3 is arranged in the isolation compartment of A60; each console is connected to network 4 and network 5 respectively, and then communicates with the RCU at the equipment layer.

[0046] The control layer is mainly used for human-computer interaction, which is the part where the operator inputs instructions to the syste...

Abstract

The invention relates to a DP-3 level dynamic positioning system and a method for guaranteeing positioning work. The system comprises a first console, a second console, a standby console, a first RCU, a second RCU, a standby RCU, three sensors, double redundancy networks, a first serial port HUB, a second serial port HUB, a master control CAN / CANOpen bus, a standby CAN / CANOpen bus, drivers, and propellers. The three consoles are respectively connected to the three RCUs through the double redundancy networks. The first RCU, the second RCU, and the three sensors are connected to the first serial port HUB. The third sensor and the standby RCU are connected to the second serial port HUB. The first RCU and the second RCU are connected to the master control CAN / CANOpen bus. The standby RCU is connected to the standby CAN / CANOpen bus. The standby CAN / CANOpen bus is connected to the master control CAN / CANOpen bus through a main / standby change over switch. The drivers are connected to the master control CAN / CANOpen bus. The propellers are connected to the drivers. Through reasonable structural arrangement, the tolerance of the DP-3 level dynamic positioning system to an external severe environment and the stability and redundancy of internal data exchange communication are fully guaranteed, and a demand of the DP-3 level dynamic positioning system from the International Marine Organization is satisfied.

Description

technical field [0001] The invention relates to a positioning system used in ship dynamic positioning, in particular to a DP-3 dynamic positioning system and a method for ensuring positioning operations. Background technique [0002] Dynamic Positioning Vessel (Dynamic Positioning Vessel) refers to a ship that automatically maintains its position (fixed position or preset track) only through propellers. [0003] Dynamic Positioning System (Dynamic Positioning System), which means all the equipment required for ship dynamic positioning, including: measurement system, power system, propulsion system and dynamic positioning control system. [0004] Dynamic Positioning Control System (DynamicPositioningControlSystem), which means all control systems and components required for dynamic positioning of ships. The dynamic positioning control system includes computer system / joystick system, sensor system, display system (control panel), position reference system and related cables, ...
