Ship operators need ship data to check the condition and efficiency of the ships they operate.

Typically, in order to transfer data collected on board to land, a portable storage device is used after entering port, and while the ship is operating, the crew organizes and compresses the data and delivers it via email. Recently, as research on remote control and digital twins has progressed in the industry, real-time analysis is being emphasized, and much attention is being paid to application to the shipping field, and there are attempts to apply land-based analysis systems to ships.

Typically, ships rely on satellite communication to communicate with land. However, satellite communication has long delays, slow speeds, uneven quality, and frequently changing IP (Internet Protocol) addresses, making it difficult to apply a system designed based on a stable terrestrial environment.

In addition, OPC (Open Platform Communications) DA (Data Access), a representative control system communication protocol, is designed to be difficult to communicate with external networks, making it difficult to apply land systems designed based on OPC DA to the shipping field. there is.

There is a technology called OPC Tunneler, which allows you to create a duplicate OPC server on an external network, but this also has the problem that it is only possible in a stable fixed IP environment.

Therefore, there is a problem that it is difficult to utilize the existing developed system immediately, and customization is required to suit the ship environment.

Embodiments of the present invention are illustrated for the purpose of explaining the technical idea of the present invention. The scope of rights according to the present invention is not limited to the embodiments presented below or the specific description of these embodiments.

Hereinafter, embodiments of the present invention will be described with reference to the attached drawings. In the accompanying drawings, identical or corresponding components are given the same reference numerals. Additionally, in the description of the following embodiments, overlapping descriptions of identical or corresponding components may be omitted. However, even if descriptions of components are omitted, it is not intended that such components are not included in any embodiment.

AMQP (Advanced Message Queue Protocol), that is, the application layer message delivery standard referred to in the present invention, refers to an MQ-based message exchange protocol for data exchange between clients, middleware, and brokers. AMQP uses a standardized network protocol without vendor dependency between heterogeneous systems. AMQP uses MQ to exchange messages as efficiently as possible in terms of cost/technology/time.

At this time, AMQP is composed of a Publisher that creates and transmits messages to the broker, a Broker that delivers/distributes the Publisher and matching messages to Subscribers, and a Subscriber that receives the matched messages from the Broker.

Additionally, the AMQP routing model consists of Exchange, Queue, Binding, etc. Here, Exchange binds the incoming MQ from Publisher and holds multiple exchange type instances. After storing the message, the Queue delivers it to the Subscriber and binds it to the message type exchange. Binding defines the exchange and queue relationship, and binds in various ways, such as 1:N and N:1. The routing key indicates the virtual address in the transmission message header, and the exchange type uses the routing key. Exchange type represents a definition algorithm for various situations, including Fan-out for routing to all queues, Direct for matching routing keys to queues 1:N, Topic for matching queues using wildcards, and key- Includes Headers, etc. determined by the value definition header.

In addition, AMQP is a program that implements the AMQP protocol and is open source. RabbitMQ, JMS client, which supports many languages and OS (Operating System), is a Java-based open source, ActiveMQ supports various languages and protocols, embedded network messaging, and is a simple It is used in ZeroMQ, etc. to efficiently transmit protocols at high speed.

The OPC (Open Platform Communications) standard protocols mentioned in the present invention include OPC DA (Data Access), A&E (Alarm & Event), HDA (Historical Data Access), DX (Data Exchange), XML-DA (XML Data Access), and There is UA (Unified Access), of which the DA standard is the most widely used and is the most suitable standard for acquiring information about control devices in real time.

The OPC server implementation process based on the OPC DA standard protocol consists of CLSID creation, DCOM/COM initialization and configuration, Graybox toolkit library initialization, OPC tag creation, OPC server class initialization, registering the OPC server in the register, and cache update. It is composed.

With CLSID, the client establishes an independent connection structure with the server, and the CLSID is used as the server's unique ID. Meanwhile, because OPC is a COM (Component Object Model)-based application, data can be exchanged between client and server components by utilizing COM runtime objects according to the client's request.

Meanwhile, the ship automatic control system, or IAS (Integrated Automation System), referred to in the present invention refers to an automated system capable of control and monitoring installed to control various processors necessary for the operation of a ship. There are various types of ship automatic control systems such as Remote Valve Control System, Ballast Control System, Power Management System, Alarm Monitoring System, and Bridge Watch Monitoring System.

This IAS refers to a DCS system applicable to high value-added vessels such as LNG (Liquefied Natural Gas) carrier, FSRU (Floating Storage and Regassification Unit), and FPSO (Floating Production Storage and Offloading). IAS is a system for maintaining the stability of the ship and integrated control of various systems within the ship. It can interface and integrate the main systems of the ship to automate the system within the ship.

It may include (128). The second AMQP server 122-1 may temporarily store received ship data and event messages. When data is stored in the message queue of the second AMQP server (122-1), the second AMQP client (122-4) connects the second AMQP server to the AMQP client-OPC DA client (127) and the AMQP client-Database client (128). Data stored in the message queue of 122-1 can be transmitted, and if communication with the ship data collection and transmission device 112 is impossible, an event message can be formed and transmitted to the second AMQP server 122-1.

The AMQP client-OPC DA client 127 can receive ship data and restore the TAG signal. According to one embodiment, the TAG signal may include TAG Name, Timestamp, Value, and Quality information. AMQP Client-Database Client 128 can receive ship data from the message queue and store it.

The second data exchanger 122-2 can control the ship data to be stored in the standby message queue in order to transmit it to the AMQP client-OPC DA client 127 and the AMQP client-Database client 128. The second event exchanger 122-3 can receive an event message and control the event message to be stored in the message queue of the target terminal.

The ship data transmission system 100 according to an embodiment of the present invention can transmit data when the ship 110 is capable of communication using the asynchronous communication characteristics of AMQP. If only the IP of the receiving device on land 120 is fixed and a stable communication environment is provided, the ship 110 can transmit data even in a dynamic IP environment or poor communication quality.

If a problem occurs, such as a situation where communication is impossible between the ship 110 and the land 120, an event message is generated on the ship 110 and the land 120 side, and an alarm message is delivered to the person in charge to take action for the situation. By doing so, system availability can be increased.

Alarm messages can be delivered to the person in charge using a variety of methods, including desktop apps, mobile apps, and email servers. If the land collection device 122 receives the data and restores the OPC DA server 123 in the same way as the ship data collection and transmission device 112, the OPC-based analysis system on land 120 can be easily linked and used. .

In addition to the OPC DA server 123, the interface server can be increased as needed, such as the database server 124 and the web service server, and a standby message queue is additionally created in the second AMQP server (122-1) and the second data exchanger ( When mapping to 122-2), data transfer preparation is completed.
