Description

  The present invention relates to a ship information collection system that collects ship information obtained by navigation of a ship, and a ship design verification system that performs verification of simulation and the like in ship design using the collected ship information.

  The ship shape has a great influence on the propulsion performance of the ship, and in order to improve the performance of the ship, it is necessary to sufficiently verify not only the power engine such as an engine but also the shape of the ship. Non-Patent Document 1 describes the development and verification results of a ship shape, particularly a bow shape, in consideration of the influence on the disturbance that the ship encounters in actual voyage. In this non-patent document 1, in order to improve the propulsion performance in the actual sea area, in addition to the improvement of the propulsion performance in the plain water, as a bow shape that can reduce the resistance increase caused by disturbance such as waves and winds A bow shape called Ax-Bow in which the bow is shaped like an ax has been proposed, and verification by a water tank test and actual ship measurement has been made.

  Conventionally, ship shape design verification is performed by computer simulation, a tank test using a model ship, or the like. Computer simulation can be verified at a relatively low cost and at high speed, so it is possible to easily verify a large number of variations with small changes to the ship shape, but the verification accuracy is low. There's a problem. On the other hand, the water tank test can perform verification with higher accuracy compared with the simulation, but has a problem that it is expensive because it is necessary to create a model ship, and verification takes time. For this reason, the verification result of the tank test by the model ship is fed back to the simulation, and the design verification of the ship shape is speeded up and the accuracy is improved by improving the accuracy of the simulation.

  However, it is difficult to completely reproduce disturbances such as waves and winds that occur on a ship in actual voyage by simulation and tank test. Therefore, it is desirable to collect information on propulsion performance during the navigation of the actually manufactured ship and feed back the collected information to the design of the next ship. In order to realize this, various sensors are mounted on the ship, and information is collected during navigation.

  In Non-Patent Document 2, a device that automatically collects and stores various types of information (for example, engine information, exercise information, weather information, and manipulated variable information) related to navigation of a ship is mounted on the ship and stored. An operation monitoring system that evaluates ships by analyzing the information on land has been proposed.

  However, the operation monitoring system described in Non-Patent Document 2 is configured to accumulate information collected in a storage device mounted on a ship and to collect information by exchanging storage media when the ship calls at a port. Therefore, for example, in the case of a ship that sails for a long period of several months or more, there is no opportunity to collect information, and there is a problem that it takes time to feed back the collected information to the design of the ship. For this reason, there is a possibility that the collected information may not be in time for the next ship design, or the next ship design may be delayed. In addition, there is a problem that information necessary for the design of the next ship cannot always be collected in one voyage.

  In addition, in a device that automatically collects information on ships that are sailing, if the information acquisition cycle (sampling cycle) is set short, the amount of information collected during a single voyage is huge and accumulates information. In order to do so, a storage device having an enormous storage capacity must be mounted on the ship. On the other hand, when the information sampling cycle is set long, there is a possibility that necessary information cannot be collected sufficiently.

  The present invention has been made in view of such circumstances, and an object of the present invention is to reliably collect information necessary for ship design along with navigation of the ship, and to collect the collected information at an early stage.

  Further, a ship design verification system according to the present invention is mounted on a ship, a ship information detecting means for periodically detecting information relating to navigation of the ship, and a ship for storing ship information detected by the ship information detecting means. Information storage means, ship side wireless communication means for transmitting / receiving information to / from a device installed on land by wireless communication, and ship information stored in the ship information storage means are periodically transmitted by the ship side wireless communication means Ship information collection device having periodic transmission means for transmitting automatically, and land side wireless communication means installed on land and transmitting and receiving information by wireless communication with ship side wireless communication means of the ship information collection device, Ship information storage means for receiving and storing ship information transmitted from the ship information collecting device by land side wireless communication means, and ship design using ship information stored in the storage means A ship design verification device having verification means for performing simulation, the ship design verification device further comprising ship information request means for transmitting a ship information acquisition request to the ship information collection device, wherein the ship information collection The apparatus further includes response transmission means for transmitting the ship information stored by the ship information storage means by the ship side wireless communication means when the acquisition request is received.

In the present invention, ship information (for example, wave height, wind direction, wind speed, ground ship speed, water ship speed, heading, rudder angle, engine horsepower, engine speed, pitch angle, roll angle, latitude or longitude) Etc.) is installed in the ship. The ship information collection device periodically transmits the stored ship information to land using wireless communication such as a mobile phone network or satellite communication.
The information relay apparatus installed on land relays transmission / reception of ship information performed between a ship information collecting apparatus mounted on the ship and a land communication apparatus installed in a land shipbuilding company or the like. That is, the information relay apparatus periodically performs wireless communication with the ship information collecting apparatus to acquire and store ship information, and transmits the stored ship information to the land communication apparatus.
In shipbuilding companies where land-based communication devices are installed, even if the ship does not call for a long period of time, it can use the ship information from the ship information collection device received via the information relay device to Design and design verification can be performed.
The on-shore communication apparatus can give a ship information acquisition request to the ship information collecting apparatus. The ship information collection device mounted on the ship periodically transmits ship information, but if the acquisition request from the land communication device is given even if it is not the timing of periodic information transmission, the ship information Send. Ship information from the ship information collecting device is transmitted to the land communication device via the information relay device. Thereby, when ship information is required for ship design or the like, the latest information can be acquired from the ship information collection apparatus by the land communication device.

  Also, instead of interposing an information relay device between the ship information collecting device mounted on the ship and the land communication device installed on land, the ship information collecting device and the land communication device communicate directly. It is good also as a structure which transmits and receives ship information. Even in this configuration, the latest ship information can be obtained by the land communication device and used for ship design or verification, as in the case described above.

  In the present invention, a wave height meter or the like is mounted on the ship, and the ship information collecting apparatus collects the wave height information. The wave height information is information such as a real wave height, a significant wave height, or a relative wave height, for example, and information such as a hull height and an encounter cycle may be collected. Since it is important information for the design of the bow shape of a ship, verification accuracy and design accuracy etc. of the bow shape can be improved by performing verification using wave height information collected during actual ship navigation. it can.

  In the present invention, the ship information collection device mounted on the ship periodically detects and accumulates information. However, an acquisition request from a land communication device is given even if the information detection timing is not periodic. If so, the ship information is detected and stored, and the stored ship information is transmitted. As a result, the on-shore communication apparatus can cause the ship information collecting apparatus mounted on the ship being navigated to detect ship information by wireless communication. That is, the land-based communication apparatus can cause the ship information collecting apparatus to detect the ship information at an arbitrary timing, acquire the latest ship information detected, and perform ship design or design verification.

  Moreover, in this invention, the setting which concerns on the period which detects ship information is transmitted from the communication apparatus for land to the ship information collection apparatus. The ship information collection device mounted on the ship periodically detects and stores ship information, but when it receives a period setting from a land communication device, it detects and stores ship information according to this setting. Change the cycle. As a result, the land-based communication device sets a cycle in which the vessel information collection device detects the vessel information, such as increasing the amount of vessel information to be collected by setting a short detection cycle when detailed vessel information is required. It can be changed arbitrarily. That is, since the accuracy of the information collected by the ship information collecting apparatus of the ship can be adjusted as appropriate by the on-shore ship design verification apparatus, ship design or design verification can be performed based on more accurate ship information.

Further, in the present invention, the land-based communication device is configured to be able to transmit a navigation instruction or the like to the crew of the ship, and the ship information collection device that has received the navigation instruction by wireless communication displays a message on a display panel or the like. The received instruction is notified to the ship occupant by means such as sound output by a speaker or the like. As a result, an instruction to change the angle of the ship with respect to, for example, waves or wind can be transmitted from the land communication device (the designer who uses it), and the crew of the ship changes the angle of the ship in accordance with this instruction. Thus, the designer can acquire ship information when the ship navigates at a predetermined angle with respect to waves or winds, and can perform ship design or design verification.
Therefore, not only passive ship design or design verification is performed using ship information that is automatically collected as the ship navigates, but ship information under desired conditions is given by the designer from the land. Can be actively collected for ship design or design verification.

  Further, in the present invention, ship information is not transmitted / received between a ship information collecting device mounted on a ship and a land communication device installed on land, but a ship information collecting device mounted on a ship, It is good also as a structure which transmits / receives ship information between the ship design verification apparatuses installed on the land. Thus, the designer can directly acquire ship information using a ship design verification apparatus that performs design verification such as simulation.

  In the case of the present invention, the ship information collection device periodically detects and stores information related to the navigation of the ship, and periodically transmits the information to the ship design verification device on land by wireless communication. By collecting the information necessary for ship design as the ship navigates, the ship information collection device collects information necessary for ship design as soon as the acquisition request is received. can do. Therefore, since it is possible to acquire the latest information related to actual vessel navigation and use it for verification of vessel design without waiting for the vessel to call at the port, the next vessel can be designed in a short period of time.

The control unit 15 of the ship information collecting device 10 first determines whether or not the wireless communication unit 14 has received a setting change request transmitted from the land server device 40 by wireless communication (step S21). When the setting change request has not been received (S21: NO), the control unit 15 stands by until a setting change request is received from the server device 40.

  When the setting change request from the server device 40 is received (S21: YES), the control unit 15 changes the collection period of the ship information by updating the setting file or the like according to the received setting change request. (Step S22). At this time, not only the ship information collection period but also other settings such as the ship information collection time may be changed. Thereafter, the control unit 15 determines whether or not an instruction to stop the setting change process has been given (step S23). If no stop instruction has been given (S23: NO), the process proceeds to step S21. Return and repeat the above process. When the stop instruction is given (S23: YES), the control unit 15 ends the setting change process.

  FIG. 8 is a flowchart illustrating a procedure of message notification processing performed by the ship information collection device 10, and is processing performed by the control unit 15 of the ship information collection device 10. First, the control unit 15 of the ship information collecting apparatus 10 determines whether or not a message such as a steering instruction has been received from the server device 40 on the land (step S31), and if no message has been received (S31: NO), wait until a message is received.

Audio output for notifying reception is performed (step S33). Thereafter, the control unit 15 determines whether or not an instruction to stop the message notification process has been given (step S34). If no stop instruction has been given (S34: NO), the process returns to step S31. The above process is repeated. When the stop instruction is given (S34: YES), the control unit 15 ends the message notification process.

  The server device 40 installed in the onshore service provider 4 periodically transmits a periodic request for requesting transmission of ship information to the ship information collecting apparatus 10 of each ship 1a, 1b at a period such as once a day. Then, ship information transmitted from the ship information collecting apparatus 10 as a response to the scheduled request is received and stored in the information storage unit 47. The periodic request transmission cycle is determined in advance and stored in the storage unit 46 as a setting file or the like, and the CPU 41 of the server device 40 transmits the periodic request according to the setting of the setting file. The periodic request transmission cycle may be different for each ship 1a, 1b.

  When the server device 40 receives a ship information transmission request from the ship simulator 50 installed on the land-building company 5a, 5b via the network 9, the server device 40 reads the ship information 47a stored in the information storage unit 47, It transmits to the ship simulator 50 which concerns on a transmission request.

It is determined whether it is a setting change related to the ship information collecting apparatus 10 installed. In the case of changing the setting related to the server device 40, the server device 40 updates the setting file stored in its storage unit 46 or the like according to the received setting change request, and performs the subsequent processing according to the new setting. In the case of a setting change related to the ship information collecting apparatus 10, the server apparatus 40 transmits a setting change request to the target ship information collecting apparatus 10 by wireless communication of the wireless communication unit 42.

  Furthermore, when the server device 40 receives a message such as a steering instruction for the vessels 1a and 1b from the vessel simulator 50, the server device 40 transmits the received message to the vessel information collection device 10 of the target vessel 1a and 1b. That is, the server apparatus 40 relays the information collection transmission request, the setting change request (limited to those related to the ship information collection apparatus 10), the message, and the like received from the ship simulator 50 and transmits them to the ship information collection apparatus 10. As a function. In addition, also when performing this relay process, the server apparatus 40 performs the authentication process based on the authentication information 47b.

  FIG. 9 is a flowchart showing a procedure of periodic ship information acquisition processing performed by the server device 40, and is processing performed by the CPU 41 of the server device 40. The CPU 41 of the server device 40 uses a timer (not shown) or the like to determine whether or not the communication time determined according to the ship information acquisition cycle set in the setting file or the like has been reached. The ships 1a and 1b are determined (step S41). If it is not the communication time for all the ships 1a, 1b (S41: NO), the CPU 41 waits until the communication time for any of the ships 1a, 1b is reached.

  When the communication time is reached for any of the ships 1a and 1b (S41: YES), the CPU 41 transmits a scheduled request by wireless communication to the ship information collection device 10 mounted on the target ship 1a or 1b (step S42). ).

When reception of all ship information is not completed (S45: NO), CPU41 returns a process to step S43 and continues reception and accumulation | storage of ship information.

  When reception of all ship information for the scheduled request is completed (S45: YES), the CPU 41 has been instructed to stop the ship information acquisition process by operating the operation unit 44, for example, or not. If the stop instruction is not given (S46: NO), the process is returned to step S41, and the above process is repeated. When the stop instruction is given (S46: YES), the CPU 41 ends the ship information acquisition process.

  FIG. 10 is a flowchart showing a procedure of relay processing of the information collection transmission request performed by the server device 40, and is processing performed by the CPU 41 of the server device 40. The CPU 41 of the server device 40 first determines whether or not the land communication unit 43 has received an information collection and transmission request transmitted from the ship simulator 50 via the network 9 (step S51), and sends the information collection and transmission request. When not receiving (S51: NO), it waits until an information collection transmission request is received.

  When the information collection transmission request from the ship simulator 50 is received (S51: YES), the CPU 41 performs an authentication process with the ship simulator 50 based on the authentication information 47b stored in advance in the information storage unit 47 ( Step S52). The authentication process can be performed, for example, by determining whether an ID (IDentifier) and a password input in the ship simulator 50 match those registered in the authentication information 47b. The CPU 41 determines whether or not the authentication process is successful (step S53). If the authentication process is not successful (S53: NO), the process returns to step S51.

  If the authentication process is successful (S53: YES), the CPU 41 sends the ship information to the ship information collection device 10 of the ship 1a, 1b registered in the authentication information 47b in association with the ship simulator 50 (or ID) that has been successfully authenticated. The information collection transmission request received from the simulator 50 is transmitted by the wireless communication unit 42 (step S54). Next, the CPU 41 receives ship information transmitted from the ship information collection device 10 as a response to the information collection transmission request by the wireless communication unit 42 (step S55), and accumulates the received ship information in the information storage unit 47 ( Step S56), it is determined whether or not the reception of all ship information for the information collection transmission request has been completed (Step S57). If reception of ship information has not been completed (S57: NO), the CPU 41 returns the process to step S55, and continues to receive and store ship information.

  When the reception of all ship information for the information collection transmission request is completed (S57: YES), the CPU 41 obtains the ship information 47a of the ships 1a and 1b related to the information collection transmission request from the ship information 47a stored in the information storage unit 47. The land communication unit 43 transmits the data to the ship simulator 50 via the network 9 (step S58). Thereafter, for example, the CPU 41 determines whether or not an operation stop operation is performed by the operation unit 44 and an instruction to stop the relay process is given (step S59). (S59: NO), the process is returned to step S51, and the above process is repeated. When the stop instruction is given (S59: YES), the CPU 41 ends the relay process of the information collection transmission request.

  FIG. 11 is a flowchart illustrating a procedure of ship information transmission processing performed by the server device 40, and is processing performed by the CPU 41 of the server device 40. The CPU 41 of the server device 40 first determines whether or not the land communication unit 43 has received a ship information transmission request transmitted from the ship simulator 50 via the network 9 (step S61), and receives the transmission request. If not (S61: NO), it waits until a transmission request is received.

  When the ship information transmission request is received from the ship simulator 50 (S61: YES), the CPU 41 performs an authentication process with the ship simulator 50 based on the authentication information 47b stored in advance in the information storage unit 47 ( Step S62). The CPU 41 determines whether or not the authentication process is successful (step S63). If the authentication process is not successful (S63: NO), the process returns to step S61.

  When the authentication process is successful (S63: YES), the CPU 41 reads out the ship information 47a of the ship 1a, 1b corresponding to the ship simulator 50 (or ID) that has been successfully authenticated from the information storage unit 47 (step S64), and reads it out. The ship information 47a is transmitted to the ship simulator 50 (step S65). Thereafter, the CPU 41 determines whether or not an operation stop operation is performed by the operation unit 44 and an instruction to stop the transmission process is given (step S66), and when the stop instruction is not given (step S66). (S66: NO), the process is returned to step S61, and the above process is repeated. When the stop instruction is given (S66: YES), the CPU 41 ends the ship information transmission process.

  FIG. 12 is a schematic diagram for explaining the accumulation of ship information performed by the server device 40. For example, the server apparatus 40 is set to perform ship information acquisition processing (transmission of a regular request and reception of ship information) related to three ships A, B, and C at a certain time. The ship information acquisition process related to the ship is ended and stored in the information storage unit 47, and the ship information acquisition process related to the ship B is being performed. The ship information related to the ship C is acquired after the acquisition process ends. It is scheduled to process.

  The ship simulator 50 can make an information collection and transmission request regardless of the processing of the server device 40. For example, when the server device 40 is performing ship information acquisition processing related to the ship B, the ship simulator 50 sends a server When the information collection transmission request concerning the ship X is given to the device 40 (see FIG. 12A), the server device 40 ends the ship information acquisition processing related to the ship B, and then ends the ship information related to the ship X. Acquisition processing (transmission of information collection transmission request and reception of vessel information) is performed, and vessel information acquisition processing relating to vessel C is performed (see FIG. 12B).

  In other words, when the server device 40 is given an information collection / transmission request from the ship simulator 50, if it is in the process of acquiring and accumulating vessel information, the server device 40 will respond to the information collection / transmission request after finishing this processing. Perform ship information acquisition processing. When a setting change request or message is given from the ship simulator 50, the server device 40 transmits a setting change request or message after finishing the ship information acquisition process in the same way as the information collection transmission request. Alternatively, the ship information acquisition process in the middle may be interrupted and a setting change request or message may be transmitted.

The CPU 41 of the server device 40 first determines whether or not the land communication unit 43 has received a setting change request transmitted from the ship simulator 50 via the network 9 (step S71), and receives the setting change request. If not (S71: NO), it waits until a setting change request is received.

  When the setting change request is received from the ship simulator 50 (S71: YES), the CPU 41 performs an authentication process with the ship simulator 50 based on the authentication information 47b stored in advance in the information storage unit 47 (step S72). ). The CPU 41 determines whether or not the authentication process is successful (step S73). If the authentication process is not successful (S73: NO), the process returns to step S71.

  When the authentication process is successful (S73: YES), the CPU 41 determines whether or not the received setting change request is a request for a setting change related to the process of the server device 40 (step S74). When the setting change request is a setting of the server device 40 (S74: YES), the CPU 41 updates the setting file stored in its own storage unit 46 (step S75) and advances the process to step S77. Thereby, the server apparatus 40 can perform the subsequent processing with the updated setting.

  When the setting change request is not a setting of the server device 40 (S74: NO), that is, when the setting change request is a request for setting change to the ship information collecting device 10 mounted on the ship 1a, 1b, the CPU 41 A setting change request from the simulator 50 is transmitted from the wireless communication unit 42 to the corresponding ship information collecting apparatus 10 (step S76), and the process proceeds to step S77. Thereby, setting change is performed in the ship information collection device 10 which received the setting change request.

  Thereafter, the CPU 41 determines whether or not an operation stop operation is performed by the operation unit 44, for example, and an instruction to stop the setting change process is given (step S77), and when the stop instruction is not given. (S77: NO), the process is returned to step S71, and the above process is repeated. When the stop instruction is given (S77: YES), the CPU 41 ends the setting change process.

  FIG. 14 is a flowchart showing a procedure of message relay processing performed by the server device 40, and is processing performed by the CPU 41 of the server device 40. First, the CPU 41 of the server device 40 determines whether or not the land communication unit 43 has received a message to the ships 1a and 1b transmitted from the ship simulator 50 via the network 9 (step S81). If not received (S81: NO), it waits until a message is received.

  When the message is received from the ship simulator 50 (S81: YES), the CPU 41 performs an authentication process with the ship simulator 50 based on the authentication information 47b stored in advance in the information storage unit 47 (step S82). The CPU 41 determines whether or not the authentication process is successful (step S83). If the authentication process is not successful (S83: NO), the process returns to step S81.

  When the authentication process is successful (S83: YES), the CPU 41 transmits from the wireless communication unit 42 to the corresponding ship information collecting device 10 from the ship simulator 50 (step S84). Thereafter, the CPU 41 determines whether or not an operation to stop the process is performed by the operation unit 44 and an instruction to stop the message relay process is given (step S85), and when the stop instruction is not given. (S85: NO), the process is returned to step S81, and the above process is repeated. When the stop instruction is given (S85: YES), the CPU 41 ends the message relay process.

  The ship simulator 50 installed in the onshore shipbuilding companies 5a and 5b is a device for a designer to perform ship design verification, and ship design information 55d to be verified is stored in the storage unit 55. The designer can verify the ship related to the design information 55d by executing the simulation program 55a in the ship simulator 50. The design verification of the ship can be performed by a process of the ship simulator 50 alone, and it is not necessary to perform a communication process with the server device 40 or the ship information collecting apparatus 10.

  Further, in order to increase the accuracy of design verification, the ship simulator 50 has a function of correcting the simulation model information 55c using the ship information 55e collected during the actual navigation of the ships 1a and 1b. The ship simulator 50 compares, for example, a simulation result 55b of a simulation performed at the time of designing the ship 1a with ship information 55e collected during navigation of the completed ship 1a, and calculates an error occurring in the simulation result 55b. The simulation model information 55c is corrected to remove this error. This improves the accuracy of design verification by using the simulation model information 55c corrected when performing a simulation such as an improved design of a ship of the same type as the ship 1a or a design of a next-stage ship developed from the ship 1a. Can do.

  When designing the shape of a ship, the resistance of water and air generated by navigation of the ship, such as air resistance, friction resistance (resistance generated by friction between the hull and water) and wave resistance (waves generated by navigation of the ship). Resistance) and the like, and it is important to reduce the wave-making resistance particularly in a ship that navigates at high speed. For example, in order to reduce wave resistance, by making the shape of the lower part of the bow spherical, the wave generated by the normal bow upper part and the wave generated by the spherical lower bow cancel each other, reducing the generation of waves be able to. In ship shape design, the shape of the bow and the amount of wave generation are verified through simulations and aquarium tests, etc. to examine the bow shape that can further reduce wave resistance. Therefore, the wave height information collected by providing the wave height meter 35 at the bow of the actual ship 1a, 1b is useful.

  Furthermore, in the ship design verification system according to the present invention, the ship information collection device 10 mounted on the ships 1a and 1b periodically collects ship information and transmits it to the on-shore server device 40 by radio. Since the ship simulator 50 can acquire the ship information accumulated in the ship 9 via the network 9, the ship designer can design the ship information of the ships 1a and 1b without waiting for the call of the ships 1a and 1b. Verification can be performed.

  Further, the ship designer can transmit not only the ship information periodically collected by the ship information collecting apparatus 10 but also the information acquisition transmission request from the ship simulator 50 to the ship information collecting apparatus 10 via the server device 40. . As a result, even if the ship information collection device 10 is outside the set information collection cycle, the ship information is collected and transmitted to the ship simulator 50. Therefore, the land designer acquires the latest ship information and performs design verification. It can be performed.

  Further, the ship designer can change settings such as a period for collecting ship information of the ships 1 a and 1 b by the ship information collecting apparatus 10 from the land ship simulator 50. Thereby, for example, the designer confirms the ship information from the ships 1a and 1b with the ship simulator 50, and when the ships 1a and 1b are navigating under specific conditions (such as weather or wind direction), The ship information under conditions useful for the designer's ship design can be collected in more detail, for example, the detection cycle can be set short and the number of ship information samplings can be increased. That is, since the land designer can change the setting of the ship information collection cycle by judging the navigation state of the ships 1a and 1b, the ship information necessary for ship design can be collected more reliably.

  Further, the ship designer can send a message to the ships 1a and 1b using the ship simulator 50. As a result, for example, an onshore designer can give an operation instruction to the crew of the ships 1a and 1b so as to navigate the ships 1a and 1b at a predetermined angle with respect to the traveling direction of waves at sea. Since it is possible to give instructions to the ships 1a and 1b to collect accurate ship information, it is possible to collect ship information necessary for ship design more reliably.

  FIG. 15 is a flowchart showing a procedure of a ship information reception process performed by the ship simulator 50, and is a process performed by the CPU 51 of the ship simulator 50. The CPU 51 of the ship simulator 50 first determines whether or not a ship information transmission request or an information collection / transmission request transmission instruction is given by an operation of the designer on the operation unit 53 (step S91), and the transmission instruction is given. If not (S91: NO), the process waits until a transmission instruction is given.

  When a transmission instruction of a transmission request or an information collection transmission request is given (S91: YES), the CPU 51 transmits a transmission request or an information collection transmission request from the land communication unit 52 via the network 9 to the server device 40 ( In step S92), an authentication process is performed with the server device 40 (step S93). Next, the CPU 51 receives ship information transmitted from the server device 40 due to the success of the authentication process (step S94), and stores the received ship information in the storage unit 55 (step S95). The CPU 51 determines whether or not the reception of all ship information related to the transmission request or the information collection and transmission request is completed (step S96). If the reception is not completed (S96: NO), the process proceeds to step S94. The process is returned and the reception and storage of the ship information is continued.

  When the reception of the ship information is completed (S96: YES), the CPU 51 determines whether or not an operation to stop the ship information is given by the operation unit 53, for example, and an instruction to stop the ship information reception process is given (step S96: YES). Step S97). When the stop instruction is not given (S97: NO), the CPU 51 returns the process to step S91 and repeats the above-described process. When the stop instruction is given (S97: YES), the ship information The reception process is terminated.

  FIG. 16 is a flowchart illustrating a procedure of a setting change request or message transmission process performed by the ship simulator 50, and is a process performed by the CPU 51 of the ship simulator 50. First, the CPU 51 of the ship simulator 50 determines whether or not a setting change request to the ship information collecting apparatus 10 or a message transmission instruction to the crew of the ships 1a and 1b has been given by an operation of the designer on the operation unit 53. (Step S101) When the transmission instruction is not given (S101: NO), it waits until the transmission instruction is given.

  When a setting change request or a message transmission instruction is given (S101: YES), the CPU 51 transmits a setting change request or message from the land communication unit 52 to the server device 40 via the network 9 (step S102). An authentication process is performed with the server device 40 (step S103). Thereby, when the authentication process is successful, the setting change request or message from the ship simulator 50 is transmitted from the server apparatus 40 to the ship information collecting apparatus 10.

  Thereafter, the CPU 51 determines whether or not a process stop operation has been performed by the operation unit 53, for example, and whether or not an instruction to stop the setting change request or the message transmission process has been given (step S104). If not (S104: NO), the process returns to step S101 to repeat the above-described process. When an instruction to stop the transmission process is given (S104: YES), the CPU 51 ends the setting change request or message transmission process.

  FIG. 17 is a flowchart showing a procedure of simulation model information correction processing performed by the ship simulator 50, and is processing performed by the CPU 51 of the ship simulator 50. The CPU 51 of the ship simulator 50 first reads the ship information 55e collected during the navigation of the ships 1a and 1b from the storage unit 55 (step S111), and also stores the simulation results 55b at the time of designing the ships 1a and 1b. (Step S112). Next, the CPU 51 calculates the error included in the simulation result 55b by comparing the read ship information 55e and the simulation result 55b (step S113). Thereafter, based on the calculated error, the CPU 51 corrects the simulation model information 55c to remove this error (step S114), and ends the process.

  The ship design verification system having the above configuration is equipped with the ship information collecting apparatus 10 that periodically detects and stores ship information in the ships 1a and 1b, and the ship information accumulated by the ship information collecting apparatus 10 is wirelessly communicated. And the server device 40 transmits the ship information via the network 9 to the ship simulator 50 installed in the shipbuilding companies 5a and 5b. Even if the port does not call over, the ship information collected by the navigation of the ships 1a and 1b can be acquired by the on-shore ship simulator 50 to verify the ship design.

  Moreover, the ship simulator 50 can transmit the information collection transmission request which requests | requires collection and transmission of ship information to the ship information collection apparatus 10 via the server apparatus 40, and the ship information collection which received the information collection transmission request By adopting a configuration in which the device 10 detects ship information and transmits the detected ship information to the ship simulator 50 via the server device 40, the latest ship information can be acquired at a timing desired by the ship designer. The ship design can be verified by the ship simulator 50 using the latest ship information.

  Moreover, the wave height meter 35 is mounted on the vessels 1a and 1b, and the vessel information collected by the vessel information collecting device 10 includes the wave height information detected by the wave height meter 35, so that information useful for the design of the vessel shape can be obtained. Since the ship simulator 50 can obtain the ship shape, it is possible to improve ship shape verification accuracy, design accuracy, and the like.

  Moreover, it is set as the structure which can change the settings, such as a detection period and detection time of the ship information by the ship information collection device 10, by transmitting a setting change request from the ship simulator 50 to the ship information collection device 10 via the server device 40. Thus, when detailed vessel information is required, the vessel designer may arbitrarily change the vessel information detection cycle according to the navigation status of the vessels 1a and 1b, such as setting the detection cycle short. The accuracy of ship information to be collected can be adjusted as appropriate.

  In addition, the ship designer 50 can use the ship simulator 50 to provide navigation instructions such as steering instructions to the crew of the ships 1a and 1b from the land. It is possible to make the ships 1a and 1b navigate to collect the ship information. That is, the ship designer not only passively verifies the ship design by using the ship information automatically collected by the ship information collecting apparatus 10 with the navigation of the ships 1a and 1b, but also from the land. Can give instructions to the ships 1a and 1b to collect ship information under desired conditions, and can actively verify ship designs, so that useful ship information can be obtained earlier and more reliably. It is possible to perform design verification by acquiring the above.

  In the present embodiment, the navigation speeds of the ships 1a and 1b detected by the ship speed detection unit 21 of the VDR 20, the wind direction detected by the wind direction detection unit 22, the wind speed detected by the wind speed detection unit 23, and the rudder angle detection unit 24. , The navigation position of the ships 1a and 1b detected by the position detector 25, the water depth detected by the water depth detector 26, the rotational speed of the engine 30 detected by the rotational speed detector 31, and the horsepower detector 32 detected Information such as the horsepower of the engine 30, the pitch angle of the ships 1a and 1b detected by the pitch angle detector 33, the roll angle of the ships 1a and 1b detected by the roll angle detector 34, and the wave height detected by the wave height meter 35, Although the ship information collecting apparatus 10 collects the ship information as ship information, the information is an example, and the ship information collecting apparatus 10 may collect other information. Further, the ship information collected by the ship information collecting apparatus 10 is used for correcting the simulation model information 55c by the ship simulator 50. However, this is only an example, and the ship information is related to ship design. It may be used for other purposes.

  In addition, the server device 40 periodically transmits a periodic request to the ship information collecting device 10 and transmits the ship information accumulated by the ship information collecting device 10 that has received the request to the server device 40. Instead, the configuration may be such that the ship information collection device 10 determines the ship information transmission timing by itself and the server device 40 receives the ship information periodically transmitted from the ship information collection device 10. Moreover, although it was set as the structure which performs an authentication process in each process shown in FIG.10, FIG.11, FIG.13-FIG. 16, it is not restricted to this, An authentication process is carried out between the ship simulator 50 and the server apparatus 40. Once successful, the authentication process may not be performed until a predetermined time elapses.

  Further, the server device 40 is installed in the service providing company 4, but the present invention is not limited to this, and the server device 40 may be installed in the shipbuilding companies 5a and 5b. Further, the ship simulator 50 may be integrally realized as one apparatus (that is, the ship information collecting apparatus 10 and the ship simulator 50 may directly communicate). In addition, the ship simulator 50 of the shipbuilding companies 5a and 5b communicates with the server device 40. However, the present invention is not limited to this, and a communication device that communicates with the server device 40 is installed in the shipbuilding companies 5a and 5b. The communication device may receive the ship information received from the server device 40 to the ship simulator 50 via an in-house LAN (Local Area Network) or a portable recording medium.
