Fast Ethernet system redundancy is benefited based on DP3 drill ships and supports method

Technical field

The present invention relates to G05B general control or regulating system technology, be based especially on DP3 drill ships benefit quickly with Too net system redundancy supports method.

Background technology

Kinematic Positioning Techniquess DP is dynamic positioning, is generally adopted on ocean engineering ship.Ocean work Operation ship of the journey ship usually away from bank, hinders for some reason and stopping production or depot repair cost are very high.It is this in order to reduce May, DP2 has been occurred as soon as, DP3.DP2 is that essentially all of system has two sets, but driver's cabin and power propulsion system only have It is a set of；But DP3 is further, not only all systems are all double sets, even driver's cabin is all double sets, two sets of driver's cabins point The two ends not all on bridge, the middle A60 for including fire door system separate；Any set of system or equipment, even move； Piggyback pod or control cabinet are burnt, and can not only survive, moreover it is possible to normal operation at sea, IMO ship class marks and ABS U.S. ship's classification Society is for the additional mark contrast of DP dynamic positionings is as can be seen that DPS3 regulations require that arbitrary cabin catches fire or immersion situation in ABS Under, throw away can keep automatically accommodation and bow to, under dimension in IMO regulation be labeled as requiring during 3 grades of equipment arbitrary cabin catch fire or In the case of immersion, position loss is not resulted in.In the ship of dynamic positioning DPS3, also one very important concept is exactly The redundancy of data process system.IMO DP3 symbols require that UPS is 2+1, and one of them is located at isolation cabin；And ABS DPS3 symbols require 1 + 1, one of them is positioned at isolation cabin.That is the main DP and UPS of standby data process system is to need to separate, and for master Two sets of systems of DP can be then what is put together.

Due to marine environment it is complicated and changeable, thus for many ship for offshore operation for, dynamic positioning system becomes must Indispensable support system.Drill ship at sea carries out drilling well work, therefore it is very high for the requirement of dynamic positioning, any Afloat stormy waves, tidal bore, will all make ship lose original position, ultimately result in operation failure, therefore which passes through gps satellite Signal, bottom mounted sonar system and gyro compass implement to vessel position and bow to a feedback, and air velocity transducer surveys Amount data are calculated to the wind area of whole ship, ship a range of wave and the measurement gushed nearby, then by control Device is manipulated to propeller, calculates automatically the torque required for horizontal and longitudinal direction, so as to a position for implementing ship is repaired, To ensure the normal enforcement of operation.Vessel position and bow to lose and affect to be very big for working ship：For For drill ship, if the situation in operation, whole drilling rod will be twisted off, and its harm is sizable.It can be seen that one efficiently, Stable control system is for the importance of drill ship.

Ship control network system is by network switching box NSB (Net Switch Box) and FS stations (Field Station) constitute.All of FS is powered by emergency switchboard all the way and another road UPS, and NSB is supplied by UPS all the way Electricity.Fast Ethernet is particularly significant for preceding aim is realized, compared with the FDDI for working under 100Mbps bandwidth originally, it has There is many, the main Fast Ethernet technology that is embodied in can effectively ensure throwing of the user on wiring basis is implemented Money, it supports the connection of 3,4, category 5 twisted pair and optical fiber, can effectively utilize existing facility.The deficiency of Fast Ethernet In fact and ethernet technology deficiency, that is, Fast Ethernet be still based on CSMA/CD technologies, when offered load it is heavier When, the reduction of efficiency can be caused, this can be made up using switching technology certainly.

With the development of network, the ethernet technology of traditional standard is difficult to meet growing network traffic data speed Degree demand.Before in October, 1993, for the LAN applications for requiring 10Mbps data above flows, only optical fiber distributed type number It is available according to interface FDDI, but it is a kind of very expensive LAN based on 100Mbps optical cables of price.In October, 1993, Grand Junction companies are proposed First Fast Ethernet hub Fastch10/100 and NIC in the world FastNIC100, Fast Ethernet technology are formally applied.Subsequent Intel, SynOptics, 3COM, BayNetworks etc. Company also releases one after another the Fast Ethernet device of oneself.At the same time, IEEE802 engineerings group is also to 100Mbps Ethernets Various standards, the such as standard such as 100BASE-TX, 100BASE-T4, M II, repeater, full duplex are studied.Nineteen ninety-five 3 The moon, IEEE announced IEEE802.3u 100BASE-T Fast Ethernet standards (Fast Ethernet), had started like this fast The epoch of fast Ethernet.

However, of the prior art generally but have critical defect with controller based on Ethernet, i.e., without standby redundancy, it is System reliability is low, and, often using Single Controller control, once controller failure, system is by nothing for existing platform energy management system Method realizes automatic control function, in some cases, is likely to result in serious consequence, and system reliability is low.Therefore, it is necessary to Implement during DPS3 drill ship Fast Ethernets, to propose that the system redundancy that a class is adapted to supports method.

A kind of deep sea semi-submersible drilling platform dual redundant EMSs of 202632066 U of Chinese patent application CN, two Platform generating set constitutes a power station, each power station independent operating, and each power station configures three control slave stations, two power station configurations one Individual dual redundant CPU controls main website, and CS31 field bus communications, man-machine interface and control are adopted between control main website and control slave station Ethernet communication is adopted between CPU in master station, is converged by ethernet communication, all ethernet ports between each control CPU in master station Ethernet switch is arrived always, final data send monitor and alarm system.
