As shown in fig. 1, the present invention provides an intelligent ship integrated information redundancy monitoring system, comprising: the system comprises an engine room data acquisition subsystem, a driving platform data acquisition subsystem, a data interface subsystem, a data network service subsystem and a ship information comprehensive display and processing subsystem; organically fusing the cabin data acquisition subsystem, the driving platform data acquisition subsystem, the data interface subsystem, the data network service subsystem and the ship information comprehensive display and processing subsystem through a lower-layer distributed redundant field CAN network, an intermediate-layer redundant global CAN network and an upper-layer redundant optical fiber Ethernet to form a whole intelligent ship comprehensive information redundancy monitoring system;
the cabin data acquisition subsystem and the cockpit data acquisition subsystem uniformly acquire data of various systems and equipment on a ship, the data interface subsystem performs data packet protocol conversion and transmission on the acquired data from a bottom layer to an upper layer, and the data network service subsystem receives the data transmitted by the data interface subsystem and redundantly stores the data in a data storage array in the system; the ship information comprehensive display and processing subsystem is communicated with the data network service subsystem to realize remote data transmission and perform visual processing on the collected data.
Preferably, as shown in a dashed line frame 1 part in fig. 1, the cabin data acquisition subsystem adopts a distributed dual-redundancy data acquisition system, and each CAN acquisition module in the cabin is distributed near the equipment connected with the CAN acquisition module to form a distributed CAN acquisition module array and is connected by a dual-redundancy CAN bus, so as to form the distributed cabin data acquisition subsystem;

Meanwhile, in order to facilitate local management, the cabin data acquisition subsystem CAN be hung with a field CAN network through a special portable operating station MOS, and status inquiry, parameter adjustment, module self-checking and the like are carried out on each distributed CAN data acquisition module on the cabin field.

Meanwhile, in order to facilitate local management, the driving platform data acquisition subsystem CAN be hung with a field CAN network through a special portable operating station MOS, and state query, parameter adjustment, module self-checking and the like CAN be carried out on each distributed CAN data acquisition module on the field of the cabin.

the second dual-processing segment controller expands a local CAN bus of the driver's station data acquisition subsystem to a global CAN bus; and then enters a second gateway server through a second CAN bus adapter card for data packet protocol conversion, and then enters an upper layer double-redundancy gigabit optical fiber Ethernet through a second optical fiber Ethernet adapter card.
Preferably, the first dual-processing segment controller and the second dual-processing segment controller are a dual-channel CAN gateway, which is a dedicated device for extending a local CAN bus; the first gateway server and the second gateway server are communication bridges between the CAN bus network and the Ethernet, and redundant connection between the global CAN network and the upper-layer Ethernet is achieved. The coordination between the first gateway server and the second gateway server, the rapid undisturbed switching, the synchronization of dual-redundancy CAN network data and other processing, the mode of an interface with an upper network, the network port of other equipment of the intelligent ship and the like. Specifically, the first gateway server and the second gateway server operate as follows:
if the first gateway server is in a normal data packet receiving and sending state, the second gateway server is in a standby state; when the first gateway server is detected to be out of order through the heartbeat line, the second gateway server is automatically put into operation; in order to avoid the problems of switching delay and the like existing in the switching process of the gateway server and the communication bus, a backup mode that the first gateway server and the second gateway server run simultaneously is adopted, and double-machine hot standby in a complete sense is realized. The heartbeat line shown by the dotted line in a dotted line frame 3 in the attached drawing 1 is specially used for point-to-point communication between two servers, a network cable between a first gateway server and a second gateway server is connected through a special network adapter card, the running state of the other side is monitored in real time through the heartbeat line through software installed on the servers, once the backup machine finds that the working machine stops service due to some reason, the heartbeat line can be reflected to the backup server, and the server is immediately put into use so as to ensure the smoothness of the network and the normal running of the service.
The working mechanism of the dual-redundancy CAN network of the data interface subsystem mainly aims at the processing of the global CANA and CANB network data such as synchronization and redundancy, and when the CAN bus or the CAN controller port of the network module connected with the CAN bus is detected to have a fault, the CANA bus is switched to the CANB bus.
The data interface subsystem and upper network interface mode: the connection with the local area network server in the data network service subsystem adopts two communication modes of UDP and TCP: the TCP mode communication is adopted for important data, so that the integrity and the reliability of data communication are ensured; the communication of non-important data is realized in a UDP mode, the data transmission does not need to establish connection, and the speed and the efficiency are high.
Preferably, the data interface subsystem is further provided with a network port for connecting with other equipment of the intelligent ship: the system CAN be further expanded by interfacing with other related devices through a standard CANopen protocol in a global CAN network of the system.

The whole system communication architecture is based on the dual redundant backbone optical fiber Ethernet, is a key system for data storage and backup of the intelligent ship and is also a starting point of a high-speed data transceiving channel.
The data network service subsystem is centrally controlled by a data platform network server in the system, and all data flow through a core switch in the system to realize data transmission in three directions: on one hand, the system is directly communicated with the data interface subsystem, receives the information of the large electromechanical system of the engine room and the information of the large control and navigation system of the driving platform transmitted by the data interface subsystem, and redundantly stores the data in a data storage array in the system to realize database management; on the other hand, a direct data transmission high-speed channel is established, and data transmitted by the data interface subsystem is directly transmitted to the intelligent ship comprehensive information display and processing subsystem through the core switch to perform subsequent display and related processing; and finally, an indirect data transmission high-speed channel is established, data transmitted by the data interface subsystem can only not be directly transmitted to the ship comprehensive information display and processing subsystem, and all data must be buffered by a database in the data platform network server and then read by the ship comprehensive information display and processing subsystem. The first of the three ways is a necessary way, and the second way and the third way are determined by the user through system setting according to the current working form.
Server hot standby redundancy: the network data server A and the network data server B are respectively connected with the corresponding core switch A and the core switch B by adopting the optical fiber Ethernet adapter card A and the optical fiber Ethernet adapter card B, so that network connection redundancy is achieved. Each server is provided with a disk storage array, and high reliability and disaster resistance of data reading and writing are achieved through cluster software. If the network data server A is in a main service state, the network data server B is in a standby state, and when the network data server A is detected to have a fault through a heartbeat line, the network data server B automatically starts to operate; in order to avoid the problems of switching delay and the like existing in the switching of the network data server and the communication bus, a backup mode that two network data servers run simultaneously is adopted, and the complete hot standby of two machines is realized. The heartbeat line shown by the dotted line in a dotted line frame 4 in the attached drawing 1 is specially used for point-to-point communication between two network data servers, a network line between the network data server A and the network data server B is connected through a special network adapter card (namely an optical fiber Ethernet adapter card A and an optical fiber Ethernet adapter card B), the running state of the other party is monitored in real time through software installed on the network data server A and the network data server B through the heartbeat line, and once a backup machine finds that a working machine stops service due to some reason, the heartbeat line can be reflected to the backup server, the network data server is immediately put into use, so that the smoothness of a network and the normal running of the service are ensured.
Switch link redundancy: two all-fiber Ethernet core switches A, B are used, one master switch and one standby switch, so as to improve the robustness and stability of the network. In the implementation process, the XRN (extensible Resilient network) technology can be used to interconnect the two core switches A, B together to form an independent three-layer switch core, so as to construct a distributed switch architecture, and the XRN technology is used to manage the distributed core architecture as a unified whole, so that the work of the two core switches A, B can be switched or distributed between two redundant links, thereby implementing a dual-core backbone network without single point failure, preventing hardware, cable or software failure, and achieving the purpose of link redundancy.
Line link redundancy: the lower layer switch of the double-core backbone network is connected to two core switches simultaneously by adopting two optical cables respectively, so that the purpose of link redundancy is achieved, and meanwhile, the core switches are provided with enough interfaces and can be used for expanding the backbone optical fiber network.
