Description

Test method for development of safe navigation support service applications based on ship simulator

The present invention relates to a test method linked to a ship simulator for the development of a safe navigation service application, and more particularly, to the development of a navigation support service application capable of supporting safe navigation and maintenance through simulation without actually sailing a ship. It is possible to generate and manage operation data, and it relates to a test method linked to a ship simulator for the development of a safe navigation support service application capable of managing operation data obtained through simulation by a ship data server.

In addition, it relates to a test method linked to a ship simulator for the development of a safe navigation support service application capable of reducing network traffic and improving transmission efficiency by applying a coding technique to operational data for exchange of operational data.

Research on real-time monitoring of the location of ships operating at sea and the status of loaded equipment has been on the rise for a long time, and shipyards, shipping companies, and manufacturers of ship equipment use safe navigation systems such as remote monitoring systems (RMS) as needed. A support service provision system has been established and is being operated. In general, these systems are used for management purposes such as checking the position of a ship, but there is a limit to accurately grasping the state of equipment in real time. In addition, in the case of most equipment and automation equipment, status checking and management functions limited to equipment supplied by each manufacturer are provided through a dedicated ship safety operation and maintenance support system, remote monitoring system, etc. As a result, there is difficulty in interface and integrated management because the relative standardization for institutions and automation-related equipment is not well established and is in an independent form.

In order to develop applications such as safe operation support and maintenance support by utilizing the operation data of these ship engines and automation-related equipment, data acquired from numerous equipment and sensors mounted on ships must be secured. A standard for data exchange is required to enable exchange with other ships. Therefore, for the purpose of overcoming these problems, ISO 19847, an international standard for ship data servers for sharing maritime field data, and ISO 19848, an international standard for data exchange formats and methods based on this, have been established to share maritime field data. has been announced

Requirements for the implementation of the vessel data server are defined in ISO 19847, but for actual application, it is necessary to define and create several to thousands of database tables depending on the number or type of data acquisition points of managed sensors and equipment. In addition, requirements for exchanging data with the management server are defined in ISO 19848, where a data channel is basically specified in the form of a uniform resource identifier (URI). Since this can be expressed in a hierarchical form using forward slashes (/), it has intuitiveness in terms of data utilization, but in terms of management and development, it is required to connect each database table with its corresponding URI.

Although the standard suggests a method for grouping data in the form of URIs by giving aliases, these are all focused on convenience for data utilization, so they are not used for managing the data, identifying the data, and transmitting the data. There is a problem with discomfort.

The platform 100 used in the present invention, as shown in FIG. 1, consists of a ship platform 110 and a land platform 120.

Here, the ship platform 110 is composed of a ship data management server 111 and a ship application (shipboard application, 112).

The ship data management server 111 includes a ship data server 111a that receives and manages operation data of equipment and integrated data management that collects, processes, and transmits the operation data received by the ship data server 111a. It includes a module (integrated data management module, 111b). Here, the integrated data management module 111b corresponds to a configuration managed according to ISO 19847 requirements, and is composed of an input function, an output function, and a data storage space according to ISO 19847 standards. The input function is divided into real-time data streaming and data stored, and the output function is divided into three types: streaming transmission service, request-response transmission service, and file transmission service. defined to transmit data.

The ship application 112 is configured to receive operation data from the ship data management server 111, and includes a real-time monitoring application 112a, a collision risk evaluation application 112b and an anomaly diagnosis application 112c. This vessel application 112 will be described in detail in the following data code transmission step (S500).

The land platform 120 includes a land data server 121 and a land application 122 receiving operation data through the ship data management server 111, and the land application 122 is a ship operation management application 122a , It includes a collision risk evaluation application (122b) and a failure and life prediction application (122c).

The life prediction and failure diagnosis method of core equipment in conjunction with the ship simulator according to the present invention using such a platform 100, as shown in FIG. 2, equipment selection step (S100), equipment simulation step (S200), operation data It includes a collection step (S300), a signal code transmission step (S400), a data coding step (S500) and an operational data transmission step (S600).

The equipment selection step (S100) means a step of selecting equipment from a ship to be simulated.

In the case of a ship, although it includes numerous equipment, it is impossible to simulate all equipment and equipment. Therefore, among these equipment, equipment related to stable operation is selected for simulation. Here, equipment related to safe navigation includes, but is not limited to, main engines, generators, lubrication, fresh water, boilers, steering, and main control panels.

The equipment simulation step (S200) means a step of simulating equipment on the route by setting a route along which the ship is operated.

In order to obtain the operation data of the equipment installed on the ship, the ship must actually operate and accumulate the corresponding operation data. Therefore, even if the ship is not directly operated, the ship's equipment is simulated so that operation data for safe operation of the equipment can be obtained.

In order to simulate these equipments, as shown in FIG. 3, a ship operation simulator is used to set a route on which the ship is actually operated, and changes in waves, currents, winds, weather changes, and marine environment changes appearing in the route are analyzed. Set up. Then, the ship is operated in the same route as the actual speed, and through this, the equipment of the ship is simulated to check the state of the equipment and equipment in the corresponding route and changes occurring in the route.

In other words, if operation is simulated through the equipment simulation step (S200), safety improvement and maintenance efficiency can be maximized through preemptive response of equipment and equipment. In addition, since it is possible to prepare to deal with abnormalities and failures of ship equipment in advance, active smart predictive diagnosis and operation support can be made possible.

The operational data collection step (S300) refers to a step of continuously collecting operational data of equipment obtained through simulation of equipment and materials and transmitting the data to the ship data management server 111. In detail, the data server 111a of the ship data management server 111 receives the operation data of equipment and materials, stores the received operation data in the integrated data management module 111b, and uses the ship application 112 by the subsequent steps. ) to transmit operation data.

Equipment includes engines and generators, which are the core facilities of ships, as well as boilers, steering, main control panels, fuel, lubricants, mechanical consumables, and electrical and electronic equipment. Therefore, in the operation data collection step (S300), the operation data of the equipment is generated while the equipment is simulated to move the route through the simulation step (S200), and the generated operation data is continuously collected to the ship data management server ( 111) is sent. After that, through the operation data transmitted to the ship data management server 111, judgments related to safe navigation, such as the lifespan and failure of equipment, are made.

The signal code transmission step (S400) means a step of coding the transmission request signal of operation data through the ship application 112 to form a signal code and transmitting the signal code to the ship data management server 111.

In order to request transmission of the operation data of the equipment that needs to be confirmed among the equipment of the ship, a signal code is formed by coding the transmission request signal containing the information indicating the equipment in question. This signal code encodes the information on the equipment with 10 digits, and in detail, as shown in FIG. 4, the system, component classification, content classification, position classification, A signal code is formed by coding according to an item. The signal code formed in this way is transmitted to the ship data management server 111 and can be retransmitted later in the form of a data code to which codes for failure types and maintenance types of equipment are added.

In the conventional case, data is basically requested using a URI (uniform resource identifier), but in this case, there is a disadvantage in that the length is long and the length is variable according to characteristics. For example, in "http://shipdatacenter.re.kr / imo1234567 / MainEngine / ExhaustGas / Temp", if the meaning is analyzed in order from the virtual upper domain address, It means the data channel for the exhaust gas temperature (Temp). This uses a slash (/) as a separator to enable hierarchical data expression, and has intuitiveness in terms of data utilization and application. However, in terms of management and development, it is required to connect each database table with the corresponding URI, and since there are dozens or thousands of ship engine part sensors, it is very complicated to express them as URIs. Therefore, in order to solve this problem, the present invention uses a signal code whose length is shorter than the URI and whose length is determined to be constant.

For example, when coding "exhaust gas output temperature of the main engine exhaust system", it can be expressed as a 10-digit code such as "00 04 05 03 11". Through this, these signal codes for indicating operation data measured from specific equipment are slightly less intuitive, but since they are based on a fixed length rather than a variable length, referring to the code table in FIG. Easy work can be done. In addition, since it is lightweight data, it is possible to obtain effects of reducing network traffic and improving transmission efficiency.

The data coding step (S500) means a step of coding the operation data transmitted to the ship data management server 111 to form a data code. At this time, the data coding step (S500) is used when the length of the operation data is long, and when the length of the operation data is not long and fast operation data exchange is possible by itself, the data coding step (S500) may not be performed. .

Among the operation data transmitted to the ship data management server 111, the operation data requested by the ship application 112 is coded to form a data code, and in detail, the corresponding signal code through the signal code transmitted from the ship application 112 Coding the operation data suitable for the operation data to form a data code. That is, data codes are formed through coding in order to identify and record abnormalities, life spans, failures, and failure types of equipment and materials. This is to standardize through coding the detailed parts, failures, and maintenance types of equipment and equipment that have failed for maintenance of equipment and equipment. focus on

When the data code is formed in this way, it has the purpose of instructing what kind of maintenance is required in case of a failure of the corresponding equipment and the purpose of recording what kind of action was taken after checking the corresponding item in the event of a specific failure. In other words, it is possible to check the occurrence of abnormality or failure through the location or type of failure, and after the operator performs a countermeasure, history, etc. can be added.

As a method of coding operation data, a 10-digit coding technique is proposed to identify equipment and express and manage failure and maintenance types together. This is done with 10-digit coding like the signal code transmission step (S400), and the code for safe navigation can be confirmed through the table of FIG. 4 in this way. As can be confirmed through FIG. 4, a system corresponding to the signal code, component classification, content classification, position classification, and item are included.

The operation data transmission step (S600) means a step of transmitting operation data matching the signal code from the ship data management server 111 to the ship application 112, and additionally transmits the operation data to the land application 122 as well. may be

In this operation data transmission step (S600), when the data coding step (S500) is not passed, the operation data itself is transmitted to the ship application 112 or the land application 122, and after the data coding step (S500), It is transmitted to the ship application 112 or the land application 122 in the form of data codes.

In the case of transmission as operating data, for example, when a signal code such as "00 04 05 03 11" coded with "exhaust gas output temperature of the main engine exhaust system" is received, 0 to 800 °C corresponding to the exhaust gas output temperature It is simply transmitted to the ship application 112 and the land application 122 as operation data for the current state within the range. If the length of operation data is long, it can be transmitted in the form of data code.

Here, the data server 112 can request operation data or data codes from the ship data management server 111 and accumulate operation data of equipment to make it big data. Big data can be configured for safety operation information of widely used equipment.

The ship application 112 may be provided on the ship and other ships to be tested. When the ship requests the operation data of the equipment to the ship data management server 111, the state of the equipment possessed by the ship can be checked. In case of requesting operation data from the ship data management server 111 of the equipment, if other ships contain the same equipment, it is possible to quickly cope with the failure by checking the operation information such as life prediction and failure of the equipment.

Here, the ship application 112 includes a real-time monitoring application 112a, a collision risk evaluation application 112b, and an anomaly diagnosis application 112c.

The real-time monitoring application (112a) corresponds to a configuration in which operation data is transmitted in real time from the ship data management server 111 in the ship, and the real-time monitoring application (112a) requests a subscription to the ship data management server 111 based on MQTT. When the operation data continuously collected in the vessel data management server 111 is transmitted as it is or is transmitted to the real-time monitoring application 112a in real time after being coded, the operator can check it.

The collision risk evaluation application (112b) sends a request signal to the ship data management server 111 and corresponds to a configuration in which operation data or data codes are transmitted only when requested from the ship data management server 111, and when requested by REST API The ship data management server 111 responds in XML and JSON. In some cases, when the operation data transmitted from the vessel data management server 111 enters within a preset range standard, the vessel data management server 111 operates as a collision risk evaluation application 112b by determining a corresponding warning. Data or data codes are transmitted.

The anomaly diagnosis application (113c) corresponds to the configuration of receiving the operation data file along with the data code, which is in the form of a file when the file is requested by accessing the FTP server, the ship data management server 111 is sent to the anomaly diagnosis application (113c) Operation data for a specific period stored as is transmitted.

In addition, the land application 122 similarly encodes the transmission request signal of operation data to form a signal code and transmits the signal code to the ship data management server 111. Thereafter, the ship data management server receives operation data or data codes from 111 so that it can respond to maintenance through life prediction and failure diagnosis of the corresponding equipment even on land.

Here, the land application 122 includes a ship operation management application 122a, a collision risk assessment application 122b, and a failure and life prediction application 122c, and other applications may be additionally provided according to the needs of the operator. there is.

The ship operation management application (122a), like the abnormality diagnosis application (113c), corresponds to the configuration of receiving the operation data file along with the data code, which connects to the FTP server and requests the file to ship data management server (111) The file is transmitted to the ship operation management application 122a.

Collision risk assessment application (122b), the same application as the collision risk assessment application (112b) included in the ship application (112) corresponds to that included in the land application (122), the same role as the collision risk assessment application (112b) Do it.

Failure and life prediction application (122c), when a subscription request is made to the ship data management server 111 based on MQTT, the operation data continuously collected in the ship data management server 111 is coded, and then failure and life in real time It is transmitted to the predictive application (122c) to diagnose abnormalities and failures of equipment or predict life according to the condition based on the operation data in real time.

This ship data management server 111 is configured to enable three types of streaming transmission, request-response transmission, and file transmission in accordance with ISO 19847, an international standard for ship data servers for sharing maritime field data. In detail, the integrated data management module 111b stores the operational data received in the ship data server 111a, and in real-time, request-response, file form according to the characteristics of the ship application 112 and the land application 122. Provide operational data. Using such operation data, the ship application 112 performs functions such as real-time monitoring, history inquiry, and abnormal diagnosis, and the land application 122 can perform functions such as failure diagnosis and life cycle prediction.

Here, the streaming transmission provides the data code requested for subscription in real-time monitoring application 112a and failure and life prediction application 122c based on MQTT, and request-response transmission is from collision risk assessment application 112b to REST API. Upon request, the corresponding data code is provided, and in the case of file transmission, operational data is provided to the abnormal diagnosis application 112c and the ship operation management word application 122a in the form of a file through FTP. That is, streaming transmission corresponds to a technology for monitoring the state of equipment in real time, and request-response transmission corresponds to a technology for evaluating collision risk.

This invention will be described in more detail through the following examples.

<Example>

A total of 8 types and 10 materials, including main engine, 3 generators, lubrication, fresh water, boiler, steering, main control panel, and other systems, are selected as key equipment for interlocking simulation in ship simulator. Then, the available data from the selected equipment was analyzed, and among them, about 280 core data necessary for life prediction and failure diagnosis were derived. After that, in order to manage data through data grouping and structure, functions such as data request, response, processing, and storage were implemented using the Ethernet interface-based Modbus TCP method. At this time, the database table was designed using Maria DB to link with the ship data server.

Next, operation data acquisition operation simulation is performed to secure engine data of the actual ship operation state by utilizing a ship simulator. The first route was a medium-distance scenario from Ulsan to Osaka, where the economic navigation speed was maintained at 12 knots, and the sea state (SS ↑ and SS ↓) was changed at a specific point. The second route was a long-distance scenario in which a tanker ship sails from Ulsan to LA, and similarly, an environmental change scenario in which the environment changes at a specific point while maintaining the economic speed was proceeded. In addition to these simulations, operation data was secured by changing the sea state in which the ship was operated. In this case, it was carried out for the purpose of confirming the changing state of equipment by simulating the extreme environment. 4 → 6 → 8 → 10 → 12 → 10 → 8 → 6 → 4 → 2 → 0 level, and after giving the environmental change step by step, operation data was secured.

Based on the above three simulations, operation data generated during the simulation is streamed in real time to the ship application requesting subscription or accumulated in the ship data server. In this embodiment, the usefulness of the ship data server was verified by utilizing a real-time monitoring application developed to check whether operation data transmitted through MQTT-based real-time streaming was normally received. At this time, in the case of real-time streaming transmission data, it was confirmed through FIGS. 6 to 8 that processing and graphs were visualized through the developed engine monitoring application. 6 is a screen of the ISO 19847-based ship data management system, and it can be seen that operation data is delivered in real time and accumulated in the ship data server. FIG. 7 shows the accumulation of operation data according to simulated routes, and FIG. It shows that the reception of operation data can be confirmed through the screen in real time through the ship application.

This operation data is transmitted not only to the ship's data server but also to land, so that operation data can be utilized in land applications. On land, it is possible to develop and test a ship safety operation support service using operational data of equipment by utilizing relatively superior computing resources than ships, and then provide feedback to the ship whether or not there is an abnormality. Furthermore, it is possible to provide a higher quality navigation support service by cross-analyzing operation data collected from multiple ships.

In this way, through the equipment simulation step (S100), operation data collection step (S200), signal code transmission step (S300), data coding step (S400) and data code transmission step (S500), life prediction and failure diagnosis of ship equipment If this is done, it is possible to develop and test a ship safety operation support service using operation data of equipment in the ship even if the ship is not actually sailing. At this time, the operation data of equipment related to life prediction and failure diagnosis is continuously or intermittently transmitted through the ship application 112 so that the operator of the ship can check, and information on the same equipment not only on the ship but also on other ships or on land is obtained. If desired, operation data may be transmitted through the ship application 112 or the land application 122 . This operational data is transmitted in the form of data code through coding to reduce storage capacity when stored in the ship data management server 111 and to reduce network traffic when transmitted to the ship application 112 and land application 122, Coding increases the visibility of information about equipment included in the data code.

The present invention is not limited to the above embodiments, and the scope of application is diverse, and various modifications and implementations are possible without departing from the gist of the present invention claimed in the claims.
