Description
Technical field
The present invention relates to a kind of dredging synthetic platform management system of trail suction dredger, especially a kind of dredging synthetic platform management system of trail suction dredger based on redundant network.
Background technology
Huge for the number of sensors on the trailing suction hopper dredger, device category is many, supervisory system is except at as the conventional ship equipment of main frame, generator, steering wheel, the dredging apparatus that also has One's name is legion, as mud door, gate valve, butterfly valve, A frame, rake pipe, these device distribution are at positions such as the deck plane of hog barge, two sides of a ship, cabin, pump room, auxilliary equipment compartment, watertight compartment, pilothouses.Existing supervisory system is distributed in each local signal of full ship in order to gather, and it is carried out Centralized Monitoring, need lay a large amount of cables, takies big quantity space, and workload is big, signal checking work complexity.For advanced trailing suction hopper dredger, along with the raising of robotization and intelligent degree, it is various comprehensively to dredge the needed computer monitoring equipment of platform management system (workstation), and the information communication amount of network system is huge.In case computer equipment damages or the network system collapse, will cause the hog barge can not normal construction, even cause the device security accident.Because in the existing supervisory system, the function opposite independent of workstation, phase trans-substitution difficulty, redundant performance is low.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of dredging synthetic platform management system of trail suction dredger with network redundancy function.
In order to solve the problems of the technologies described above, dredging synthetic platform management system of trail suction dredger based on redundant network of the present invention, comprise the network switch, server, workstation, PLC and gateway, described each several part is connected in two fiber annular networks, promptly is responsible for the bottom looped network of bottom data input and output control and the top layer looped network of responsible upper layer data management and monitoring; Described PLC is used to realize the input and output controls (as dredging plant control, warning, engine room facilities control etc.) to hog barge work on the spot equipment, described gateway is used for realizing the conversion between third party's agreement and the ICP/IP protocol, and PLC is connected with the bottom looped network by each self-corresponding network switch respectively with gateway; The a plurality of described workstation that is used for carrying out data management and monitoring is connected with the top layer looped network by its corresponding network switch; Described server is connected bottom looped network and top layer looped network by the bottom looped network with the network switch on the top layer looped network respectively, and described server has 3 at least, and wherein at least 2 station servers are connected the bottom looped network respectively as bridge with the top layer looped network.
After adopting above structure, ring-like net among the present invention has at first been avoided the redundancy of cable, and respective switch connects and composes ring nearby, and network has redundancy feature simultaneously, and the switch in certain network node or certain section cable break down, and can not have influence on the communication of other network nodes.Carry out seamless the connection by server between bottom looped network and the top layer looped network, make that the bottom looped network is fully transparent with respect to the top layer looped network, reached the abundant of full ship information resources and shared, realized that trailing suction hopper dredger is real-time, concentrate, distribute, efficiently and easily controlled and supervision.Adopt looped network can avoid the fault of network communication medium, when a certain section communication media in the looped network broke down, network is automatic reconfiguration within a certain period of time, and the self-healing time is smaller or equal to 500ms, thereby had improved the reliability of system.
As a further improvement on the present invention, switch on each looped network adopts optical fiber to be connected, and described bottom looped network and top layer looped network comprise three network switchs respectively at least, have 2 groups of optical fiber interfaces, 2 RJ45 interfaces at least.
After adopting above structure, optical fiber is during as transport vehicle, its data transmission capabilities height, communication distance is long, and volume is little, cost is low, capability of resistance to radiation is strong, and particularly antijamming capability is strong, because because the communication of optical fiber relies on light signal, and non-electrical signal, thereby in long Distance Transmission process, can not be subjected to any electromagnetic interference (EMI).
