Referring to FIG1 , a ship integrated management system includes:

Multiple redundant PLC controllers 1 are connected in series, and each PLC controller 1 is connected to multiple access networks 9. Multiple central control system HMI hosts 4 are located in different cabins of the ship, and each central control system HMI host 4 is connected to multiple access networks 9. Multiple data acquisition modules are connected in series and connected to the equipment of the first type system 10 of the ship through Ethernet. Multiple redundant switches 8 are connected in series and connected to the equipment of the second type system 11 of the ship through Ethernet, and connected to the equipment of the third type system 12 through a serial port. PMS controller 2 is connected to multiple redundant PLC controllers 1, multiple data acquisition modules and multiple redundant switches 8 located in the same cabin of the ship through an MRP ring network.

The second type of system 11 includes: side propulsion drive system, main propulsion drive system, lifting system, crane system. In the present utility model, each system represents a set of devices in the system that realize certain specific functions. Such systems are all known and will not be described in detail.

It should be noted that the PMS (Power Management System) controller refers to a controller used to manage the power management system. The MRP (Media Redundancy Protocol) ring network is a redundant network suitable for industrial automation industry applications. Another redundant network suitable for industrial automation industry applications is the high-speed redundant ring network HSR ring network.

In this embodiment, an MRP ring network is used, and a maximum of 50 PROFINET devices can be connected to the MRP ring network. A maximum of 15,360 digital signals can be connected to the MRP ring network. A maximum of 3,840 analog signals can be connected to the MRP ring network. The entire ship automation integrated management system has strong expansion capabilities and is suitable for most ships. When a single node in the MRP ring network fails, it does not affect the normal operation of other PROFINET devices in the network, so it has strong reliability.

It should be noted that PROFINET refers to an automation bus standard based on industrial Ethernet technology launched by PROFIBUS International (PI). PROFINET is compatible with industrial Ethernet and existing fieldbus technologies (such as PROFIBUS, Interbus, DeviceNet). The PROFINET IO system includes the following PROFINET devices: IO controller, which controls the automation task work, corresponding to the multiple redundant PLC controllers 1 of the utility model, IO devices, which are generally field devices, controlled and monitored by the IO controller, and an IO device may include several modules or sub-modules, corresponding to the PMS controller 2 of the utility model, multiple data acquisition modules and multiple redundant switches 8. The IO monitor is a PC software that can set parameters and diagnose the status of individual modules, corresponding to the multiple central control system HMI hosts 4 of the utility model. The PROFINET IO system will establish an application relationship (Application Relation, AR) between the IO controller and the IO device, and the application relationship will define communication relationships (Communication Relations, CR) with different characteristics such as parameter transfer, periodic data exchange and warning processing.

In this embodiment, multiple PLC controllers 1 are connected to the PMS controller 2, multiple data acquisition modules and multiple redundant switches 8 using optical fiber and CAT6 network cables. Each PLC controller 1 has a separate RS-485 communication module, which can perform RS-485 extended communication with the equipment of the third-category system 12 through multiple redundant switches 8, and the communication speed is relatively fast. Multiple PLC controllers 1 back up each other. When a PLC controller 1 in the MRP ring network fails, it can quickly switch to another PLC controller 1 to ensure stable operation of the system. Among them, the equipment of the third-category system 12 refers to: VDR system, dynamic positioning system, fire and gas system, master and slave clock system, loading computer system and water mist system, etc. Such systems are all known and will not be described in detail.

It should be noted that the VDR (Voyage data recorder) system has the function of a ship's black box and is used to record navigation data.

In this embodiment, each central control system HMI host 4 located in different cabins of the ship can confirm and mute alarm information, remotely operate fans and circuit breaker valves in other systems, and perform status detection and remote measurement of liquid levels on generators in other systems. The different cabins refer to: the front control room, the rear control room, and the centralized control room.

In this embodiment, the data of each system are transmitted to the PLC controller 1 through the MRP ring network, and the data of each system, such as: data of the power management system, data of the main propulsion drive system and data of the side propulsion drive system, remote control valve data of the bilge system, liquid level data of the fuel system and alarm data of the alarm system, are displayed and warned on the central control system HMI host 4 connected to the PLC controller 1 through multiple redundant switches 8.

It should be noted that the number of multiple redundant PLC controllers 1, multiple central control system HMI hosts 4, multiple data acquisition modules, and multiple redundant switches 8 is at least 2. In this embodiment, the number of PLC controllers 1 is 4, which are installed in 4 PLC control cabinets respectively, the number of PMS controllers 2 is 1, and the PMS controller 2 is installed in the PMS control cabinet, there are 3 data acquisition modules, which are installed in 3 data acquisition boxes respectively, the number of redundant switches 8 is 4, and there are 4 central control system HMI hosts 4, which are scattered in the front control room, rear control room, and centralized control room of the ship. Among them, the PLC control cabinet, PMS control cabinet, data acquisition box, and multiple redundant switches 8 are located in the main power distribution room of the ship.

In summary, the utility model forms an MRP ring network through a PMS controller, multiple redundant PLC controllers, multiple data acquisition modules, and multiple redundant switches located in the same cabin, thereby improving the redundancy and security of the system backbone network. By hanging an access network on each redundant PLC controller, each central control system HMI host located in different cabins is connected to multiple access networks respectively, forming a one-network multi-plane network architecture, thereby improving the security of the network. Various systems of the ship are connected to the MRP ring network through data acquisition modules and multiple redundant computers, and are controlled by multiple redundant PLC controllers, thus changing the current problem that various systems are relatively isolated and cannot be integrated. At the same time, various systems of the entire ship can be controlled through the central control system HMI host located in each cabin, thereby realizing a distributed control method and improving the reliability of control.
