The present invention relates to marine vessel smart poles to communicate with marine vessels, marine vessel communication connection devices, and marine vessel communication connection systems.
In recent years, a relatively small marine vessel such as a planing boat is equipped with a data communication module (DCM) which performs wireless communication (see, for example, Japanese Patent Application No. 2022-007725). The DCM connects a navigating marine vessel to an information communication network such as the Internet by wireless communication, and an occupant of the marine vessel can enjoy various services via the information communication network.
There are not many targets and indicators on the sea or a lake unlike on land, and thus, it is necessary to use a device mounted on the marine vessel in order to know a current position of the marine vessel on the marine vessel. However, the DCM does not provide position information. Therefore, usually, the marine vessel acquires the current position of the marine vessel using a global positioning system (GPS).
However, the position information obtained by a GPS includes errors in units of several meters, and thus, it is difficult to acquire a precise current position of the marine vessel, and the occupant of the marine vessel cannot receive a service that is premised on the presence of the precise position information of the marine vessel. Therefore, there is still room for improvement from the viewpoint of allowing the occupant of the marine vessel to obtain the benefits of the service.
Example embodiments of the present invention enable occupants of marine vessels to obtain the benefits of services that are premised on the presence of precise position information of the marine vessel.
A marine vessel smart pole according to an example embodiment of the present invention includes a wireless transmitted configured or programmed to perform a communication function to communicate with a marine vessel and an object other than the marine vessel, and a position information function to provide a position of the marine vessel smart pole to at least one of the marine vessel or the object other than the marine vessel.
According to the above configuration, since the marine vessel smart pole provides the marine vessel with the position of the marine vessel smart pole, a precise current position of the marine vessel can be acquired without using a GPS from the position of the marine vessel smart pole and a relative positional relationship between the positions of the marine vessel smart pole and the marine vessel. As a result, an occupant of the marine vessel is able to obtain the benefits of a service that is premised on the presence of precise position information of the marine vessel.
According to example embodiments of the present invention, occupants of marine vessels are able to obtain the benefits of services that are premised on the presence of the precise position information of marine vessels.
The above and other elements, features, steps, characteristics and advantages of the present invention will become more apparent from the following detailed description of the example embodiments with reference to the attached drawings.
Example embodiments of the present invention will be described below with reference to the drawings.
The marine vessel smart pole 10 is different from a conventional mooring pile in terms of being configured or programmed to perform each of functions to be described below. When the marine vessel smart pole 10 is located on water, the marine vessel smart pole 10 can be used as the mooring pile, and a marine vessel or a pier including a floating structure can be moored to the marine vessel smart pole 10. In addition, since the functional portion 12 of the marine vessel smart pole 10 is configured or programmed to perform a communication function to be described below, when the marine vessel smart pole 10 is located on water, the functional portion 12 is attached to the pile portion 11 such that the functional portion 12 is located above the water surface. It should be noted that the marine vessel smart pole 10 merely needs to be capable of mooring a marine vessel or the like and performing each of the functions to be described below, and a structure thereof need not be limited to the structure shown in
The light 13 is an indicator that provides an indicator function of notifying a navigating marine vessel of a location of the marine vessel smart pole 10 by emitting light as a landmark. The light 13 includes, for example, an LED lamp or an incandescent lamp, but its structure is not limited as long as it can emit light. In addition, the light 13 may also serve as a signal indicator, and in this case, the light 13 may indicate a navigation control signal of a route or a warning signal indicating the presence of a reef or a navigation obstacle.
The wireless transmitter 14 includes an antenna 18 and provides a communication function of performing wireless communication with at least one of a marine vessel or a communication object other than the marine vessel, for example, an information communication network such as the Internet, an information processor such as a server of a port facility, or another marine vessel smart pole. The wireless communication performed by the wireless transmitter 14 corresponds to long-range communication using a mobile phone line or short-range wireless communication such as Wi-Fi (registered trademark) or Bluetooth (registered trademark).
The wireless transmitter 14 of the functional portion 12 of the marine vessel smart pole 10 receives position information and an identification signal of the marine vessel from the marine vessel, and transmits route information, position information of the marine vessel smart pole 10, and a guidance command to be described below to the marine vessel. In addition, the wireless transmitter 14 receives a guidance command from the communication object other than the marine vessel, and transmits the received position information and identification signal of the marine vessel, an identification number of the marine vessel smart pole 10, the position information of the marine vessel smart pole 10, and neighborhood or local area information to be described below to the communication object other than the marine vessel. The guidance command is a command to guide the marine vessel toward the marine vessel smart pole 10, and the marine vessel that has received the guidance command moves toward the marine vessel smart pole 10 that has transmitted the guidance command. It should be noted that details of the guidance of the marine vessel will be described below.
The wireless transmitter 14 provides a position information function by transmitting the position information of the marine vessel smart pole 10 to the marine vessel or the communication object other than the marine vessel. The position information transmitted at this time is position information acquired using, for example, an electro-optical distance measuring instrument or the like when the marine vessel smart pole 10 is installed and stored in a memory or the like. Therefore, the position information provided by the position information function has higher accuracy than position information acquired by a GPS. It should be noted that the position information is stored in a memory or the like of the marine vessel smart pole 10.
The information collector 15 is configured to collect information regarding a neighborhood situation of the marine vessel smart pole 10 (hereinafter, referred to as “neighborhood information”), and includes, for example, a plurality of monitoring cameras 19 provided on the marine vessel smart pole 10. The information collector 15 acquires a peripheral image obtained by each of the monitoring cameras 19 as the neighborhood information, or acquires information, obtained by image analysis of the peripheral image, as the neighborhood information. The information obtained by the image analysis of the peripheral image includes, for example, information regarding whether or not the marine vessel is moored on the marine vessel smart pole 10 or information regarding whether or not the marine vessel has anchored at or in a vicinity of the marine vessel smart pole 10. In addition, the information obtained by the image analysis of the peripheral image may be the number of marine vessels anchored at or in a vicinity of the marine vessel smart pole 10 or the number of marine vessels moored at a pier 26 (described below) corresponding to the marine vessel smart pole 10. These pieces of neighborhood information are transmitted from the information collector 15 to the wireless transmitter 14, and as described above, the wireless transmitter 14 transmits the neighborhood information to the communication object other than the marine vessel such that the wireless transmitter 14 provides a neighborhood information function. The neighborhood information may be transmitted to the marine vessel by the wireless transmitter 14.
In addition, the information collector 15 may receive a GPS radio signal and correct the position information of the marine vessel smart pole 10 based on the received GPS radio signal when the marine vessel smart pole 10 has moved due to an external factor such as a tidal current or the like. It should be noted that the position information of the marine vessel smart pole 10 can be corrected with higher accuracy in a case where the information collector 15 receives not the GPS radio signal but a radio signal from a Quasi-Zenith Satellite System.
The information collector 15 acquires the neighborhood situation by the respective monitoring cameras 19, but may acquire the neighborhood situation by using radio detection and ranging (RADAR) or light detection and ranging (LIDAR) instead of or in addition to the monitoring cameras 19. Since RADAR and LIDAR are hardly affected by the surrounding environment and the weather, the neighborhood situation can be acquired more accurately.
The power storage 17 includes a power storage function of storing electricity generated by, for example, a solar cell panel 20 included in the functional portion 12. The power storage 17 supplies the stored electricity to each component of the functional portion 12. As a result, the functional portion 12 can operate even if electricity is not supplied from outside the marine vessel smart pole 10. It should be noted that power generation in the functional portion 12 is not limited to solar power generation using the solar cell panel 20, and may be tidal power generation using tides. In this case, for example, relative movement between the marine vessel smart pole 10 and the pier 26 due to tides is used as an electromotive force.
The CPU 16 controls the operation of each component of the functional portion 12 in accordance with a predetermined program stored in a memory or the like or a command from outside the marine vessel smart pole 10.
The marine vessel smart pole 10 communicates with a neighboring marine vessel 22a provided with a DCM 21 by short-range wireless communication using the wireless transmitter 14 of the functional portion 12, and also communicates with another marine vessel smart pole 10a and a port facility 24 including a server 23 by, for example, short-range wireless communication. In addition, the marine vessel smart pole 10 communicates with a distant marine vessel 22b using, for example, a mobile phone line via the information communication network 25. In this case, for example, position information and an identification signal of the marine vessel 22a are transmitted from the neighboring marine vessel 22a to the marine vessel smart pole 10, and position information and a guidance command of the marine vessel smart pole 10 are transmitted from the marine vessel smart pole 10 to the neighboring marine vessel 22a. In addition, position information, neighborhood information, and route information of the marine vessel smart pole 10 are transmitted from the marine vessel smart pole 10 to the distant marine vessel 22b via the information communication network 25. Position information and an identification signal of the marine vessel 22b are transmitted from the distant marine vessel 22b to the marine vessel smart pole 10 via the information communication network 25.
Further, another marine vessel smart pole 10a transmits neighborhood information and position information of the other marine vessel smart pole 10a to the marine vessel smart pole 10. The port facility 24 transmits a guidance command to the marine vessel smart pole 10. The neighborhood information and the position information of the marine vessel smart pole 10 are transmitted from the marine vessel smart pole 10 to the other marine vessel smart pole 10a. The marine vessel smart pole 10 transmits the identification number and the position information of the marine vessel smart pole 10, the neighborhood information, and the position information and the identification signals of the marine vessels 22a and 22b to the port facility 24.
In addition, the marine vessel smart pole 10 functions as a relay point. For example, when the neighboring marine vessel 22a communicates with the marine vessel smart pole 10 and the marine vessel smart pole 10 further communicates with the other marine vessel smart pole 10a or the port facility 24, the neighboring marine vessel 22a can communicate with the other marine vessel smart pole 10a or the port facility 24 using the marine vessel smart pole 10 as the relay point. Further, when the port facility 24 provides a short-range wireless communication service such as Wi-Fi (registered trademark), an occupant of the neighboring marine vessel 22a can cause the marine vessel smart pole 10 to function as a child device and communicate with the information communication network 25 using the short-range wireless communication service. In this case, a communication cost can be reduced as compared with a case where the DCM 21 of the neighboring marine vessel 22a communicates with the information communication network 25 using a mobile line.
As described above, the identification number, the position information, and the neighborhood information of the marine vessel smart pole 10 are transmitted from each of the marine vessel smart poles 10 to the port facility 24. As a result, the server 23 of the port facility 24 is able to determine at which finger 29 the marine vessel 22 is docked or moored, and can determine a location of each of the marine vessels 22. Therefore, the server 23 can efficiently manage each of the berths 28 of the pier 26.
Further, since the server 23 can determine the location of each of the marine vessels 22, when the port facility 24 provides a rental service or a management service of the marine vessels 22, the server 23 can determine a departure situation and a return situation of each of the marine vessels 22 without any declaration from the occupant of each of the marine vessels 22. As a result, the rental service and the management service can be efficiently performed.
Further, as described above, the marine vessel 22 docked to each of the fingers 29 can communicate with the port facility 24 via the corresponding marine vessel smart pole 10. As a result, it is possible to reduce the labor of the occupant of the marine vessel 22 by, for example, enabling the occupant of the marine vessel 22 to submit a departure declaration and a return declaration to the port facility 24 using communication.
In addition, since the server 23 also receives the identification number and the position information, and the neighborhood information of the marine vessel smart pole 10 from the marine vessel smart pole 10 spaced away from the pier 26, it is possible to determine at which marine vessel smart pole 10 the marine vessel 22 is moored. In this case, the quality of the rental service can be improved by, for example, enabling a transportation boat 30 to be dispatched to the marine vessel smart pole 10 as a part of the rental service or the management service of the marine vessel 22. It should be noted that the transportation boat 30 is guided based on the position information of each of the marine vessel smart poles 10 transmitted from the marine vessel smart poles 10.
As described above, if automated transportation by the transportation boat 30 based on the communication with the marine vessel smart pole 10 is performed, only the marine vessel smart pole 10 may be installed in the port to manage the rented marine vessel 22 to perform the rental service or the management service of the marine vessel 22, and it is not necessary to install the pier 26. Therefore, it is possible to provide the rental service or the management service of the marine vessel 22 at a low cost.
In addition, in this automated docking, it is not necessary to perform image recognition of the finger 29 of the pier 26 by a camera or the like, and thus, it is not necessary to provide an automated docking system based on conventional image processing which is expensive, and it is possible to reduce the cost of the marine vessel 22.
Each of the marine vessel smart poles 10 transmits at least one of a congestion situation or a reservation situation of the associated service providing facility to the information communication network 25 as neighborhood information. It should be noted that the transmitted neighborhood information may include a congestion situation and a reservation situation of the pier 26 corresponding to each of the service providing facilities. The transmitted neighborhood information may further include an identification number of the marine vessel smart pole 10 associated with each of the service providing facilities and position information of each of the service providing facilities.
The marine vessel 22 communicates with the information communication network 25 by the DCM 21 to receive the congestion situations and the reservation situations of these service providing facilities as the neighborhood information. As a result, an occupant of the marine vessel 22 can know the congestion situations and the reservation situations of the respective service providing facilities.
In addition, the occupant knowing the congestion situations and the reservation situations of the service providing facilities transmits a reservation request of a desired service providing facility to the marine vessel smart pole 10 associated with the service providing facility via the information communication network 25. Here, when the identification number of the marine vessel smart pole 10 is included in the reservation request, the reservation request can be reliably delivered to the marine vessel smart pole 10 associated with the desired service providing facility as the identification number included in the reservation request is referred to. Then, the marine vessel smart pole 10 that has received the reservation request transfers the reservation request to the associated service providing facility. As a result, the occupant of the marine vessel 22 can reserve the desired service providing facility even if the occupant is away from the desired service providing facility. In addition, each of the service providing facilities are able to attract occupants of the marine vessel 22 only by installing the corresponding marine vessel smart pole 10.
The marine vessel smart pole 10 of the artificial floating body 34 transmits information regarding an event carried out on the artificial floating body 34 and a congestion situation of the water surface at or in a vicinity of the artificial floating body 34 to the information communication network 25 as neighborhood information. It should be noted that the transmitted neighborhood information may include an identification number of the marine vessel smart pole 10 of the artificial floating body 34 and position information of the artificial floating body 34.
Then, the marine vessel 22 communicates with the information communication network 25 by the DCM 21, thus receiving the neighborhood information transmitted by the marine vessel smart pole 10 of the artificial floating body 34. As a result, an occupant of the marine vessel 22 can know the content of the event carried out on the artificial floating body 34 and whether or not the occupant can approach the artificial floating body 34. In addition, an organizer who carries out the event can obtain an opportunity to attract the occupant of the marine vessel 22 only by installing the marine vessel smart pole 10 on the artificial floating body 34.
Each of the marine vessel smart poles 10 surrounding the entry prohibited area 35 transmits the presence of the entry prohibited area 35, position information of each of the marine vessel smart poles 10, and a relative positional relationship between each of the marine vessel smart poles 10 and the entry prohibited area 35 to the information communication network 25 as route information. In addition, each of the marine vessel smart poles 10 along the route 36 transmits information regarding the presence of the route 36, position information of each of the marine vessel smart poles 10, a relative positional relationship between each of the marine vessel smart poles 10 and the route 36, and regulations (navigation classification, speed, or the like) of the route 36 to the information communication network 25 as route information.
Then, the marine vessel 22 communicates with the information communication network 25 by the DCM 21 to receive the route information transmitted from each of the marine vessel smart poles 10 surrounding the entry prohibited area 35 and each of the marine vessel smart poles 10 along the route 36. As a result, the marine vessel 22 can know the presence and positions of the entry prohibited area 35 and the route 36, and can easily avoid the entry prohibited area 35 and follow the route 36.
At this time, it can be said that each of the marine vessel smart poles 10 surrounding the entry prohibited area 35 and each of the marine vessel smart poles 10 along the route 36 exhibit a route information function. When the plurality of marine vessel smart poles 10 cooperate to function in this manner, it can be said that the plurality of marine vessel smart poles 10 define a marine vessel smart system (marine vessel communication connection system).
According to an example embodiment, the marine vessel smart pole 10 provides the marine vessel 22 with the position of the marine vessel smart pole 10. Therefore, the precise current position of the marine vessel 22 can be acquired without using a GPS from the provided position of the marine vessel smart pole 10 and the relative positional relationship between the marine vessel smart pole 10 and the marine vessel 22. As a result, the occupant of the marine vessel 22 is provided with precise position information of the marine vessel 22 such as highly accurate automated docking.
In addition, in an example embodiment, since the marine vessel 22 receives the position information and the neighborhood information of the marine vessel smart pole 10, the occupant of the marine vessel 22 can know the congestion situation and the reservation situation of the service providing facility, the content of the event carried out on the artificial floating body 34, and the like. That is, since the number of options of services that can be received by the occupant of the marine vessel 22 increases, it is convenient for the occupant of the marine vessel 22 to stay on water, and it is possible to enhance the comfort and leisure of using the marine vessel 22.
Although example embodiments of the present invention have been described above, the present invention is not limited to the above-described example embodiments, and various modifications and changes can be made within the scope of the gist of the present invention.
For example, the marine vessel smart pole 10 includes the communication function, the position information function, the neighborhood information function, and the route information function (hereinafter, collectively referred to as a “smart service function”) in the above-described example embodiments, but any structure may be used to implement example embodiments of the present invention as long as the marine vessel smart pole 10 can provide the smart service function. For example, instead of the marine vessel smart pole 10, a connection device 37 (marine vessel communication connection device), which is a simple device as shown in
In addition, the connection device 37 is able to be attached to other instruments, equipment, and existing structures. For example, the connection device 37 may be attached to a buoy 38 that is an artificial floating body as shown in
It should be noted that, since the smart service functions can be provided only by attaching the connection device 37 to existing instruments, equipment, and structures, the connection device 37 can make it easier for the occupant of the marine vessel 22 to use the smart service functions as compared with the marine vessel smart pole 10 that needs to be newly installed.
While example embodiments of the present invention have been described above, it is to be understood that variations and modifications will be apparent to those skilled in the art without departing from the scope and spirit of the present invention. The scope of the present invention, therefore, is to be determined solely by the following claims.
