Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings.

[0024] 1. Alarm information database initialization module

[0025] This module is an auxiliary function module other than the DP3 control system. According to the engineering experience of DP experts and engineers, combined with the fault events of DP system in history, it is summarized and organized into a fault information table. The function of this module is to import the fault information table into the alarm information database.

[0026] 2. On-site workstation (FoundationStation, FS) fault detection module

[0027] The internal computer of the local workstation is the direct control computer of the propeller or rudder, and is the bridge between the controller and the propeller or rudder, and its control quantity and feedback quantity are all analog signals. The FS fault detection module includes each FS computer (equipped with a board card with AD / DA convers...

Abstract

The invention relates to a DP3 level dynamic positioning failure alarm information system for realizing failure detection and alarm display of the DP3 system. The DP3 level dynamic positioning failure alarm information system comprises an FS (Foundation Station) failure detection module, a controller failure detection module, a failure detection module and a alarm information display module. The FS failure detection module is connected with the controller failure detection module in parallel; the failure detection module is in sequential connection with the FS failure detection module; the failure detection module is in sequential connection with the controller failure detection module; the alarm information display module is in sequential connection with the failure detection module. The system is more suitable for redundancy conditions of the DP3 dynamic positioning system, the failure detection is comprehensive and accurate, and the alarm information is richer.

Description

technical field [0001] The invention relates to a DP3 level dynamic positioning fault alarm information system for realizing the fault detection and alarm display of the DP3 system. Background technique [0002] Dynamic Positioning Vessel (Dynamic Positioning Vessel) refers to a ship that automatically maintains its position (fixed position or preset track) only by propeller thrust. [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. Dynamic positioning control system includes computer system / joystick system, sensor system, display system (control panel), position reference system and related cables and lines. [0005] The I...
