  On the other hand, in the fishery field, information that affects the catch is important. For example, in the scallop fishery, there is a fishing method in which the coastal sea area is divided into sea areas like a field and the scallop juvenile is released and operated in order. Normally, in such a scallop fishery, it is decided by the fishermen's cooperatives etc. in which sea area to operate, but it is not decided where in the sea area each ship operates. There is no control over where the car was operated.

  For this reason, when the operating locations of all ships are combined, there is a possibility that the operating locations within the sea area are biased, and there is a concern that efficiency may be reduced due to uncollected items.

  An object of this invention is to provide the management server which can operate efficiently by managing the position where the fishing operation | work was performed. Another object of the present invention is to provide a remote monitoring system including the management server.

  A remote monitoring system according to the present invention includes the above-described management server and a remote monitoring terminal device that is provided in a ship and transmits the current location information and the operation information.

  According to the present invention, the operation position where the fishing work is performed can be managed by the management server. Therefore, by using the operation position where the fishing operation is performed in the future operation plan, it is possible to efficiently operate while avoiding duplication of the operation position.

  According to the present invention, the operation information includes at least one of the ship speed, the engine speed, and the engine load, so that an almost accurate operation position can be obtained.

  Further, according to the present invention, it is possible to easily calculate the operation position with a small amount of processing by determining that the fishing work has been performed when the value of the operation information is within a predetermined range set in advance.

  According to the present invention, since the predetermined range can be arbitrarily set, it can be set in consideration of external factors such as the wave height according to the season, so that the operation position can be calculated with high accuracy. Can do.

  Further, according to the present invention, by superimposing the positions where the fishing operations of a plurality of ships are performed on a map, the operation positions can be shared by a plurality of ships such as fishery cooperatives, and future operation plans. By using the operation position where the fishing work was performed, it is possible to efficiently operate while avoiding duplication of the operation position.

<Remote monitoring system>
FIG. 1 is a block diagram showing a schematic configuration of a remote monitoring system for remotely monitoring a ship. The remote monitoring system 10 includes a management server 2 and a remote monitoring terminal device 3 provided in each of the one or more ships 1 and connected to the management server 2 via a communication network 4.

  The management server 2 is installed at an office of an onshore fishermen's cooperative, where current location information indicating the current location (current latitude and longitude) of the vessel 1, operational information indicating the operational status of the vessel 1, and fishing work are performed. It stores (accumulates) operation position information and the like indicating the position. Information stored in the management server 2 is output to a display unit connected to the management server 2 and used by a user such as a member of a fishery cooperative.

  The remote monitoring terminal device 3 and the management server 2 can be transmitted and received between the remote monitoring terminal device 3 and the management server 2 by being connected to each other via the communication network 4. Has been. Thereby, the ship 1 can be remotely monitored at the office of the fishery cooperative, or the information stored in the management server 2 can be read out by the ship 1 and can be confirmed by the crew.

  The communication network 4 can be a wireless communication network or a communication network that combines a wired communication network and a wireless communication network. The communication network 4 is typically a public line network applied by a telecommunications carrier and can be a public line network in which terminals such as fixed telephones and mobile phones communicate with each other.

<Remote monitoring terminal device>
FIG. 2 is a block diagram illustrating a schematic configuration of the remote monitoring terminal device 3. The remote monitoring terminal device 3 includes a communication unit 31, a GPS sensor 32, a position detection unit 33, a position information storage unit 34, and a control unit 35. Further, the remote monitoring terminal device 3 may be configured such that a display unit 36 such as a liquid crystal panel and an operation unit 37 such as a keyboard are externally connected. Further, the remote monitoring terminal device 3 is connected to the ship control device 38. The ship control device 38 controls the electric system of the ship 1 including the engine. For example, the ship control device 38 outputs operation information of the ship 1 to the remote monitoring terminal device 3 in response to a request from the remote monitoring terminal device 3.

  The operation information is information whose value changes depending on the operation status of the ship 1, and is information indicating a specific value at the time of fishing work. As the operation information, ship speed, engine speed, engine load, exhaust temperature, boost pressure, net winch operation, and the like can be used. Details of the operation information will be described later.

  The communication unit 31 can communicate with the same communication protocol (communication protocol) as the communication unit of the management server 2 in the office of the fishery cooperative. Information transmitted and received at the time of communication is converted by the communication unit 31 so as to follow the communication protocol. And the communication part 31 transmits the present location information and operation information which were acquired in the control part 35 to the management server 2, or receives operation position information from the management server 2. There is no particular limitation on the transmission timing of the current location information and the operation information to the management server 2. For example, the current location information and the operation information may be transmitted every time the current location information is acquired. You may send it.

  The GPS sensor 32 is a sensor that receives radio waves from GPS satellites. The position detection unit 33 detects the current location of the ship 1 based on the radio wave received by the GPS sensor 32. The detection frequency of the current location can be set at, for example, 1 minute intervals. Further, the position detector 33 may detect speed information and azimuth information of the ship 1. The position information storage unit 34 includes a volatile memory such as a RAM (Random Access Memory), and temporarily stores the position information detected by the position detection unit 33. Information in the location information storage unit 34 is treated as current location information and transmitted to the management server 2.

  The control unit 35 includes a processing unit 351 composed of a microcomputer such as a CPU (Central Processing Unit) and a storage unit 352 such as a ROM (Read Only Memory), a RAM, a hard disk drive, and a flash memory. The control unit 35 controls the operation of various components by causing the processing unit 351 to read out and execute a control program stored in advance in the ROM of the storage unit 352 on the RAM of the storage unit 352. Specifically, transmission / reception of information at the time of communication, various input / output controls, control of arithmetic processing, and the like are performed. The storage unit 352 also stores map information.

  An input (instruction) by the operation unit 37 is accepted by the input control of the control unit 35. Then, the operation position information received from the management server 2 is displayed on the display unit 36 via the ship control device 3 by the output control of the control unit 35. Thereby, the sailor can confirm the operation position information managed by the management server 2 on the ship 1. Accordingly, since the sailor can check the operation position information at any time, the sailor can operate efficiently so that the operation place is not biased.

  Note that the battery for the remote monitoring terminal device may be provided separately from the battery of the ship 1. The battery for the remote monitoring terminal device may be built in the remote monitoring terminal device 3, or may be installed and connected outside. According to this, communication is possible even in a key-off state, and the remote monitoring system 10 can be used. For example, the present location information and operation information for one day can be transmitted to the management server 2 by using the key-off after returning to the port as a trigger.

<Management server>
FIG. 3 is a block diagram illustrating a schematic configuration of the management server 2. The management server 2 is a desktop personal computer, for example, and includes a communication unit 21 and a control unit 22. In addition, a display unit 23 such as a liquid crystal panel and an operation unit 24 such as a keyboard are externally connected to the management server 2. Note that the display unit 23 and the operation unit 24 may be configured to be included in the management server 2 (for example, a notebook personal computer).

  The communication unit 21 can communicate using the same communication protocol as the communication unit 31 of the remote monitoring terminal device 3. Information transmitted / received at the time of communication is converted by the communication unit 21 in accordance with the communication protocol. Then, the communication unit 21 receives current location information and operation information of the ship 1 from the remote monitoring terminal device 3, or transmits operation position information and update information related to the control of the vessel 1 to the remote monitoring terminal device 3.

  The control unit 22 includes a processing unit 221 including a microcomputer such as a CPU, and a storage unit 222 such as a ROM, a RAM, a hard disk drive, and a flash memory. The control unit 22 controls the operation of various components by causing the processing unit 221 to read and execute a control program stored in advance in the ROM of the storage unit 222 on the RAM of the storage unit 222. Specifically, transmission / reception of information at the time of communication, various input / output control, calculation processing control, and the like are performed. The storage unit 222 also stores map information, current location information, operation information, and operation position information.

  The processing unit 221 calculates operation position information based on the current location information and the operation information. Specifically, when the value of the operation information is within a predetermined range set in advance, it is determined that the fishing work has been performed, the current location information corresponding to the operation information is set as the operation position information, and the operation position information is set to the date and time. The data is stored in the storage unit 222 in correspondence. The operation position information can include information other than the current location information. The reason why the operation position information can be estimated in this way will be described below.

  FIG. 4 is a diagram showing the ship speed, the engine speed, the exhaust temperature, and the boost pressure from the departure of the ship 1 to the return port. FIG. 5 is an enlarged view of a broken line portion of FIG. Describing from departure to return with reference to the ship speed, first, the ship 1 that has left the port increases its speed, and when it reaches a speed of about 10 knots, it moves to the target operating place while maintaining that speed. And when it arrives at the target operating point, it stops, throws in the net, and performs the netting work at a low speed. The netting work of scallop fishing is usually performed at a boat speed of about 2 to 3 knots. When the netting work is completed, the net winding work is performed at a reduced speed. Then, when the winding is completed, the speed is increased to about 10 knots, the next operation place is moved, and the net is inserted again. In scallop fishing, this netting operation is repeated 10 to 20 times a day. When the daily fishing work is completed, the ship 1 increases its speed toward the port and returns to the port that left the port while maintaining the speed when the speed reaches about 10 knots.

  Therefore, when using the boat speed as the operation information, for example, if the boat speed of 0.5 to 5 knots is within a predetermined range for determining that the fishing work has been performed, the moving state can be excluded. The state during the netting operation (fishing operation) can be extracted. Therefore, it can be determined that the fishing work has been performed when the boat speed is within the predetermined range, and the current position information corresponding to the operation information can be used as the operation position information.

  The predetermined range can be arbitrarily set by the user. For example, when the wave is high due to factors such as the season, the netting operation is performed at a slower boat speed than usual, so the predetermined range may be set to a slower range (for example, 0.2 to 4 knots).

  Further, as is clear from FIG. 4, the engine speed, the exhaust temperature, and the boost pressure behave in the same manner as the ship speed. Therefore, if an appropriate predetermined range is set, it can be used as operation information. is there. Even when the engine speed, the exhaust temperature, or the boost pressure is used as the operation information, the predetermined range can be arbitrarily set.

  Moreover, the operation position information can be calculated with high accuracy by using a plurality of information as the operation information, and the place where the fishing work has been performed can be identified more accurately.

  Further, the engine load can be used as the operation information. The engine load can be obtained from, for example, the engine speed and the fuel consumption. Since the engine load behaves similarly to the ship speed, it can be used as operation information by setting an appropriate range. Even when the engine load is used as the operation information, the predetermined range can be arbitrarily set. In addition, when using an engine load as operation information, it is preferable to use together with other information, such as time and a ship speed, in order to improve a precision.

  The operation of the net winch can also be used as the operation information. In this case, the operation of the winch is controlled by the ship control device 38, for example, by detecting the direction of rotation of the winch, until the winch rotates in the direction of winding up the net after the winch rotates in the direction of inserting the net. It can be determined that fishing is being performed.

  Returning to the description of FIG. 3, the operation position information stored in the storage unit 222 is displayed on the display unit 23 by the output control of the control unit 22. Specifically, an image in which the operation position is superimposed on a map is displayed. Further, the operation position information is transmitted to the remote monitoring terminal device 3 by the output control of the control unit 22. The operation position information is transmitted when there is a request from the remote monitoring terminal device 3. On the other hand, the input (instruction) by the operation unit 24 is accepted by the input control of the control unit 22.

  The operation position information can be processed and displayed in various forms. For example, displaying the daily operating position of one ship 1, displaying the operating position of one ship 1 per month, displaying the operating positions of a plurality of ships 1 per day, One month operation positions of the plurality of ships 1 can be displayed. In this way, by managing the position (operating position) where the fishing work is performed, it is possible to efficiently operate while avoiding duplication of the operating position.

  In addition, when the operation positions of a plurality of ships 1 are displayed superimposed on a map, if the operation positions of the respective ships 1 are displayed in different colors, it is easy to grasp the operation positions for each ship, so that it can be used effectively for future planning. it can.

<Example>
Below, the Example which applied said remote monitoring system 10 to scallop fishing which repeats discharge and operation of scallop juvenile is described.

  FIG. 6 is a diagram for explaining a sea area for scallop fishing. The shaded area indicates the land, and the broken line indicates the sea area. The broken line portion is actually a virtual line without a break such as a net. The sea area is divided into 4 areas A to D. This is because scallop larvae can be harvested in 4 years, so they move and operate in the sea area in turn every year. Therefore, there is no particular limitation on the number of sea areas. Point F indicates a fishing port from which ship 1 departs and returns.

  FIG. 7 is a diagram showing a track of one month of one ship 1. The wake 11 for a month indicated by a thick solid line is configured by displaying the wake for each month on the map in a superimposed manner for one month. The track for one day can be generated on the management server 2 side by connecting the current location information of the ship 1 for one day in time series. From the wake 11 of FIG. 7, it can be seen that the ship 1 leaves the fishing port F and returns to the fishing port F via the four sea areas A to D. However, from the wake 11 it cannot be specified where the fishing work is being performed.

  Therefore, in order to specify the position where the fishing work is performed, the management server 2 calculates operation position information indicating the position where the fishing work is performed based on the current location information and the operation information received from the remote monitoring terminal device 3.

  FIG. 8 is a flowchart showing the operation of the management server 2 regarding the calculation of the operation position. First, in step S <b> 10, the management server 2 acquires current location information and operation information for one month for one ship 1. As for both information for one month, the data transmitted each time the ship 1 acquires the current location information may be stored in the storage unit 222, or the ship 1 returns to the port after completing the operation of the day. The data that are sometimes transmitted together may be stored in the storage unit 222.

  Next, it progresses to step S11 from step S10, and the management server 2 reads the operation information at the time of acquiring present location information and the present location information in time series order. And it progresses to step S12 and the management server 2 determines whether the value of operation information is in the predetermined range set beforehand.

  If the value of the operation information is within the predetermined range set in advance in step S12, it is determined that the fishing work has been performed, and the process proceeds to step S13 to plot the position of the current location information on the map. On the other hand, if the value of the operation information is outside the predetermined range set in advance in step S12, it is determined that the fishing work is not performed, and the process proceeds to step S14, and the position of the current location information is not plotted on the map.

  The process proceeds from step S13 and S14 to step S15, and it is determined whether or not it is the last current location information in time series. In step S15, when it is not the last, it returns to step S11, and when it is the last, it progresses to step S16 and memorize | stores the data plotted on the map in the memory | storage part 222 as one month operation position information. The operation position information for one month is displayed on the display unit 36 by the operation of the operation unit 37. Thereby, the plan for the next month can be made with reference to the bias of the operation position information. In addition, the operation position information can be received from the management server 2 by the remote monitoring terminal device 3 of the ship 1 and displayed on the display unit 36. Thereby, since the operation position information can be confirmed on the ship, convenience is improved.

  FIG. 9 is a diagram showing the operation position information calculated from the data of FIG. This is the result of calculating the predetermined range as 0.5 to 5 knots using the ship speed as the operation information. It can be seen that the operation position 12 for one month indicated by the thick solid line is within the sea area A. With reference to this result, it is possible to make a plan for the planned operation place such as operation so as to eliminate the bias of the operation position in the sea area A.

  Moreover, it turns out from FIG. 9 that it is not operating in other sea areas B-D. From this, it can be said that there is no illegal operation. In this way, the operation position information can also be used for monitoring illegal operations. Usually, it is costly to monitor a illegal operation because a monitoring ship has to be sent out. However, using the remote monitoring system 10 can reduce the cost.

  In addition to calculating the monthly operation position information for one ship 1, the operation position information for one month for all the ships 1 operating in the same sea area is added and superimposed on the map. May be. According to this, it is possible to manage the operation place in the fishery cooperative, and it is easy to plan the allocation of the operation place for the next month of each ship.

  FIG. 10 is a diagram showing the operating time distribution calculated from the data of FIG. ○ indicates a place where the operation time is long (for example, 100 hours or more), x indicates a place where the operation time is short (for example, less than 10 hours), and △ indicates a place where the operation time is between ○ and x It shows that there is. The operation time at each position can be calculated by, for example, calculating the number of overlapping plots at each position in FIG. According to FIG. 10, since it can be understood how long the operation was performed at each location for each location, it can be effectively used for planning the operation location for the next month.

  Note that the data collection period is not limited to one month, and may be one day, one week, one year, or the like.

<Others>
The remote monitoring system 10 can also have functions such as operation time management, plan management, fuel consumption management, abnormality occurrence management, and maintenance management in addition to the operation position management for managing the position where the fishing work is performed. . Each management information can be calculated and stored in the management server 2 and displayed on the display unit 23 on the management server 2 side or the display unit 36 on the remote monitoring terminal device 3 side.

  The operation time management is a function for managing information obtained by tabulating the time from departure to return of each ship 1 over a predetermined period (for example, one day, one week, one month, one year, etc.). Thereby, the operation time of each period of each ship 1 can be grasped | ascertained. Moreover, you may manage the operation time when fishing work was actually performed. The operation time can be calculated based on the acquisition time of the current location information corresponding to the operation position information. Then, the work efficiency can be calculated by obtaining the ratio of the operation time to the operation time in the management server 2.

  Plan management is a function for managing information describing the future operation schedule. For example, information describing the ship name, the scheduled operation date, and the planned operation location can be used. And if a user operates the operation part 24 and designates a date and a ship name, a scheduled operation place will be displayed on a map. The planned operation location may be input by the user with reference to past operation position information. The plan may be input on either the management server 2 side or the remote monitoring terminal device 3 side, and the input information is stored in the management server 2 and shared on the remote monitoring system 10.

  The fuel consumption management is a function for managing information indicating so-called fuel consumption. For example, it may be information indicating the daily fuel consumption, or may be information indicating the fuel consumption during movement or the fuel consumption during fishing work. Furthermore, when the relationship between the engine speed and the boost pressure is added, it can be used as a reference for low fuel consumption operation.

  The abnormality occurrence management is a function for managing information indicating the engine operating status and the like acquired by the ship control device 38. For example, if the water level of the cooling water is managed, a warning can be given with a display or voice when it is detected that the water level is lower than the specified water level, so that the problem can be dealt with early.

  Maintenance management is a function for managing the timing of maintenance. For example, by managing the replacement interval and usage time of consumables such as fuel filters and engine oil, it is possible to notify the time of replacement by display or sound. In addition, by managing the exchange history, it is possible to grasp the past maintenance situation.

  Next, when the remote monitoring system is used in a large-scale system such as when used in a plurality of fishery cooperatives, the following configuration may be used.

  FIG. 11 is a block diagram showing a schematic configuration of another form of remote monitoring system. The remote monitoring system 100 is provided in each of the management server 2 and one or more ships 1 and is connected to the management server 2 via the communication network 4 and the management server 2 via the network 6. And one or more user terminal devices 5 connected to each other. The management server 2 is installed in a remote monitoring center such as a system management company, and a user terminal device 5 that can communicate with the management server 2 is installed in a facility on the user side such as a fishery cooperative.

  The configuration and functions of the management server 2 are as follows in addition to those described above. The management server 2 is connected to a user terminal device 5 such as a personal computer, a tablet computer, or a mobile terminal via a network such as a LAN (Local Area Network) or the Internet. The information stored in the management server 2 is read by the remote monitoring terminal device 3 and used by a sailor, and is read by the user terminal device 5 and used by a user such as a fishery cooperative member. It has become so.

  The configurations and functions of the remote monitoring terminal device 3 and the communication network 4 are the same as those described above, and a description thereof will be omitted.

  FIG. 12 is a block diagram illustrating a schematic configuration of the user terminal device 5. The user terminal device 5 is, for example, a desktop personal computer, and includes a communication unit 51 and a control unit 52. In addition, a display unit 53 such as a liquid crystal panel and an operation unit 54 such as a keyboard are externally connected to the user terminal device 5. The display unit 53 and the operation unit 54 may be configured to be included in the user terminal device 5 (for example, a notebook personal computer).

  The communication unit 51 can communicate using the same communication protocol as the communication unit 21 of the management server 2. Information transmitted and received at the time of communication is converted by the communication unit so as to follow the communication protocol. The communication unit 51 receives operation position information, management information, and the like from the management server 2 and transmits information related to plan management to the management server 2.

  The control unit 52 includes a processing unit 521 including a microcomputer such as a CPU, and a storage unit 522 such as a ROM, a RAM, a hard disk drive, and a flash memory. The control unit 52 controls the operation of various components by causing the processing unit 521 to read out and execute a control program stored in advance in the ROM of the storage unit 522 onto the RAM of the storage unit 522. Specifically, transmission / reception of information at the time of communication, various input / output controls, control of arithmetic processing, and the like are performed.

  Due to the output control of the control unit 52, the operation position information received from the management server 2 is displayed on the display unit 53. Specifically, an image in which the operation position is superimposed on a map is displayed. On the other hand, the input (instruction) by the operation unit 54 is accepted by the input control of the control unit 52.

  According to such a remote monitoring system 100, the user terminal device 5 is a general personal computer, and the high-performance management server 2 is installed in the remote monitoring center. It is also possible to cope with the case where it is necessary to process data. In addition, since the user does not need to install an expensive management server 2, initial investment can be suppressed.
