According to the redundant device disclosed by the utility model, the safety and the reliability of a power station are increased through soft redundancy.
Description
Technical field
The utility model relates to a kind of ship power station management system (PMS), relates in particular to a kind of redundant apparatus of ship power station management system, belongs to the Ship Power Station technical field.
Background technology
The Ship Power Station is the heart of modern ships, the Ship Power Station directly has influence on navigation safety, the reliable power supply in power station is the necessary condition of the normal operation of full ship all devices, and safety and the reliability of Ship Power Station are depended in the fail safe of dynamic positioning system to a great extent.
Abominable due to the watercraft engine room environment, as electromagnetic interference signal, the vibrations of boats and ships, rock and be subjected to the impact of ambient temperature, marine air etc., can make some Ship Power Station automation equipments produce fault or job insecurity, during dynamic positioning during because of unexpected excess load, can not reliably working as the power management system, can cause whole interruptions of power supply, finally cause vessel position and course displacement to occur, thereby bring even personnel casualty accidents of heavy economic losses.Therefore the power management systems technology with redundancy feature that is applicable to dynamic positioning has become the new development of Ship Power Station automation and has driven gesture.
Summary of the invention
The purpose of this utility model is to provide a kind of ship power station management system redundant apparatus, increases fail safe, the reliability in power station.
a kind of ship power station management system redundant apparatus comprises client CPU module A 1, client CPU module B 2, the first ethernet communication processor 3, the second ethernet communication processor 4, three-ethernet Communication processor 5, Ethernet switch 6, service end CPU module 7, a plurality of signal acquisition module 8, described client CPU module A 1 is connected with the first ethernet communication processor 3, described client CPU module B 2 is connected with the second ethernet communication processor 4, described service end CPU module 7 is connected with three-ethernet Communication processor 5, described the first ethernet communication processor 3, the second ethernet communication processor 4, three-ethernet Communication processor 5 carries out network with Ethernet switch 6 by Internet tcp/ip communication agreement and is connected, be connected by the modbus bus between described a plurality of signal acquisition module 8 and service end CPU module 7.
Compared with prior art, the beneficial effects of the utility model are: increase system reliability by soft redundancy, continued to carry out the user program assembly by standby station after master station breaks down, increased fail safe, the reliability in power station; Redundant system can be managed the faults such as broken string that the CPU fault that causes because of hardware fault or software error and communication cable occur; By communication modes can the remote monitoring unit running status, the power station is integrated in monitoring and controlling system for engine room, shows the running status of power station power management system and actual parameter and the switch of main distribution board is carried out straighforward operation on each work station of integrated automation system.
Description of drawings
Fig. 1 is system construction drawing of the present utility model;
Fig. 2 is the soft redundancy of effort flow chart of the utility model.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.as shown in Figure 1, the utility model comprises client CPU module A 1, client CPU module B 2, the first ethernet communication processor 3, the second ethernet communication processor 4, three-ethernet Communication processor 5, Ethernet switch 6, service end CPU module 7, a plurality of signal acquisition module 8, described client CPU module A 1 is connected with the first ethernet communication processor 3, described client CPU module B 2 is connected with the second ethernet communication processor 4, described service end CPU module 7 is connected with three-ethernet Communication processor 5, described the first ethernet communication processor 3, the second ethernet communication processor 4, three-ethernet Communication processor 5 carries out network with Ethernet switch 6 by Internet tcp/ip communication agreement and is connected, be connected by the modbus bus between described a plurality of signal acquisition module 8 and service end CPU module 7.
The present embodiment PLC master controller is partly selected Siemens S7-200, adopt the mode of soft redundancy to realize that zero of master-salve station switches, the hardware concrete configuration is as follows: 2 of client CPU module (CPU 226), 3 of ethernet communication processors (CP243-1), 1 of Ethernet switch (EKI2525), 1 of service end CPU module (CPU 226), some signal acquisition module (carrying out signals collecting for generator control module PPU in the power management system).Hardware configuration configuration principle: the hardware configuration at two stations must complete one to, must copy to from first station second station.Network between two clients connects can pass through Internet TCP/IP, be connected by Internet TCP/IP between two clients and service end, be connected by the modbus bus between a plurality of signal acquisition module and service end CPU module, this network is to carry out data communication for I/O.
As shown in Figure 2, under normal circumstances, gather the service end signal by customer end A, whole electric power station system is controlled, when customer end A is out of order, as cpu fault, power failure and network communication fault etc., automatically switch to customer end B, realize that zero of main website and slave station is switched.
In addition to the implementation, the utility model can also have other execution modes, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection range of the utility model requirement.
