[0. Overview]
First, an outline of an embodiment of the present invention will be described.

In recent years, a technique for detecting an object to be detected by a sensor has been known. For example, there is known a technique of detecting the direction of a detection object based on an acoustic signal obtained by a microphone and controlling the shooting direction of a camera so as to match the direction of the detected detection object. In such a technique, when an object to be detected is detected from an image taken by a camera, an image showing the object to be detected is automatically transmitted. The user can grasp that the detection target has been detected by looking at the automatically transmitted image of the detection target.

In the embodiment of the present invention, we mainly propose a technique capable of further improving the convenience of the user. More specifically, in the embodiment of the present invention, when the detection target object is detected based on the sensor data, the identification information corresponding to the information related to the detection is transmitted to the user's terminal. Then, when the identification information is specified by the user, the information regarding the detection is transmitted to the user's terminal. As a result, the user can confirm the information related to the detection at his / her own convenient timing by using the terminal, which is expected to improve the convenience of the user.

In the embodiment of the present invention, it is mainly assumed that an acoustic sensor is used as the sensor. That is, in the embodiment of the present invention, it is mainly assumed that the detection target is detected by detecting the sound emitted by the detection target from the sensor data (sound data) obtained by the acoustic sensor. However, the sensor is not limited to an acoustic sensor, and may be a sensor other than an acoustic sensor (for example, an image sensor and an ultrasonic sensor). Even when a sensor other than the acoustic sensor is used as the sensor, the detection target can be detected by detecting the characteristics of the detection target from the sensor data, as in the case where the acoustic sensor is used as the sensor. ..

Various objects are assumed as the detection objects. For example, it can be assumed that the detection target is various objects used for poaching. Examples of various objects used for poaching include poaching boats and poachers. This allows poaching to be monitored by the user. It is clear that it is important to monitor poaching in view of the magnitude of damage caused by poaching in recent years and the difficulty of finding poaching. For example, the Japan Coast Guard Annual Report "Japan Coast Guard Annual Report 2018" (http://www.kaiho.mlit.go.jp/info/books/report2018/html/honpen/2_04_chap3.html) is based on "Japan Coast Guard Annual Report 2018". The abundant fishery resources of Japan are by no means inexhaustible, and rules such as setting restrictions on catches, operating methods, areas, and periods are set in order to maintain the balance of the ecosystem and prevent the depletion of fishery resources. There is no end to illegal operations by some fishermen who do not comply, and overexploitation of fishery resources by gangsters aiming to secure funds. We will endeavor to strictly monitor and crack down on malicious and sophisticated poaching offenses. We will continue to work closely with related organizations and fishery-related organizations to meet the characteristics of the region. We will promote comprehensive measures against poaching, such as preventive measures, and strive to maintain fishery order. " Therefore, when a poaching boat or a poacher is set as a detection target, the embodiment of the present invention is intended to solve a social problem, and the embodiment of the present invention can be more preferably implemented.

Here, poaching is generally understood as "breaking the law and secretly fishing" (Daijirin), fishing without a license or permission, and various types of prohibited fishing and prohibited fishing laws. It is understood to be a violation of laws and regulations, a violation of fishing rights, and so on. For example, the Kyoto Prefectural Fisheries Office, which is a branch office of the Ministry of Agriculture, Forestry and Fisheries of Kyoto Prefecture, which handles operations related to the fishery industry, said, "Poaching means taking organisms subject to fishery rights without permission." (Https://www. pref.kyoto.jp/suiji/documents/mitsuryou.pdf).

For example, the difficulty in finding poaching is due to the following reasons. That is, poaching is often carried out in a dark environment at night. Therefore, it is difficult to detect poachers and poachers visually or by camera. In addition, in bad weather conditions (eg snowfall, typhoons, sea fog, swells, high waves, etc.), visibility is poor, so it is not possible to detect poachers and poachers visually or with cameras during the day. Even so, it is difficult. In addition, poaching of marine resources existing on the seabed (for example, sea cucumbers, sea urchins, turban shells, abalone, oysters, pearls, etc.) is often carried out by diving by poachers, so the seabed is visually checked by guards or by a camera. It is difficult to monitor the poaching of the resources that exist in the sea urchin.

Considering the difficulty of detecting such poaching, it is desirable to use an acoustic sensor as a sensor when a poaching boat or a poacher is a detection target. The reason is that the accuracy of sensing by the acoustic sensor is hardly affected by the brightness of the environment (time zone) and the good visibility (weather conditions). Further, if the sensing unit of the acoustic sensor is located underwater, the acoustic sensor can easily detect a poacher who is trying to obtain a resource existing in the sea. Hereinafter, the acoustic sensor in which the sensing unit is located underwater is also referred to as an “underwater acoustic sensor”.

In the following, it is mainly assumed that the user is a "watcher" who monitors poaching and the user's terminal is a "watcher terminal" used by the watcher.

The outline of the embodiment of the present invention has been described above.

[1. Details of the embodiment]
Subsequently, the details of the embodiment of the present invention will be described.

[1-1. System configuration]
First, a configuration example of the system according to the embodiment of the present invention will be described. In the following, assuming that the system according to the embodiment of the present invention is used for measures against poaching, the system according to the embodiment of the present invention is also referred to as "IoT (Internet of Things) system for measures against poaching". However, the system according to the embodiment of the present invention may be used for other than the measures against poaching (that is, the system according to the embodiment of the present invention is not limited to the IoT system).

FIG. 1 is a diagram showing a configuration example of a poaching countermeasure IoT system according to an embodiment of the present invention. As shown in FIG. 1, the poaching countermeasure IoT system 1 includes an underwater acoustic sensor 10-1 to 10-N (N is an integer of 1 or more), a server 20, and a monitor terminal 30-1 to 30-M. (M is an integer of 1 or more). In the following, when it is not necessary to distinguish each of the underwater acoustic sensors 10-1 to 10-N, each of the underwater acoustic sensors 10-1 to 10-N is also referred to as "underwater acoustic sensor 10". Similarly, when it is not necessary to distinguish between the observer terminals 30-1 to 30-M, each of the observer terminals 30-1 to 30-M is also referred to as a "monitorer terminal 30".

In the embodiment of the present invention, it is mainly assumed that the observer terminals 30-1 to 30-M are used by different observers. However, a plurality of observer terminals 30 may be used by one observer, or one observer terminal 30 may be used by a plurality of observers.

In the embodiment of the present invention, it is assumed that the underwater acoustic sensor 10 communicates with the server 20 existing on the Internet via a mobile network such as an LTE (Long Term Evolution) network. However, the underwater acoustic sensor 10 may be able to communicate with the server 20 by other communication means.

On the other hand, the server 20 can be realized by a computer having a server function.

Further, in the embodiment of the present invention, it is mainly assumed that the observer terminal 30 is composed of a smartphone. However, the observer terminal 30 includes a tablet terminal, a mobile phone, a business phone (key telephone) (button telephone), a PDA (Personal Digital Assist), an audio player, a printer, a facsimile, a scanner, a copy machine, and a digital device. Cameras, automation equipment (ATMs (cash machines) (automated teller machines) (automatic teller machines) that are used by an unspecified number of people and automatically handle things (things), vending machines, vending machines, kiosque terminals, etc.) Alternatively, it may be realized by other devices such as a cash processing machine (a terminal that manages cash in and out), a wearable computer, and a car navigation system. Then, the observer terminal 30 may communicate with the server 20 by wireless communication via a mobile network such as an LTE network or wired communication via a wired network such as a LAN (Local Area Network).

[Underwater Acoustic Sensor 10]
The underwater acoustic sensor 10 obtains sensor data (acoustic data) by sensing the environment. Further, the underwater acoustic sensor 10 acquires information (sensor state information) indicating its own state (for example, normality, failure, unknown state, etc.). When the underwater acoustic sensor 10 obtains the sensor data and the sensor state information, the underwater acoustic sensor 10 transmits the sensing data and the sensor state information to the server 20. The data format of the sensing data and the sensor status information transmitted to the server 20 is not limited, and for example, CSV (Comma-Separated Values), TSV (Tab-Specified Values) file, SSV (Space-Specified Values), SSV (XML) -Separated Values), HTML (HyperText Markup Language), XML (Extensible Markup Language), XHTML (Extensible HyperText Page)

Here, "sensing" means detection of estimated amounts of sound, vibration (vibration), temperature, humidity, inclination, etc. (detection of increase / decrease or generation), and detection of generation of smoke, chemical substances, static electricity, etc. ( It is used as a word to express (detection of increase / decrease and estimated amount). Further, "sensing" is used as a word indicating a process of converting the detected content into a signal in addition to the detection. Further, "sensing" is used as a word indicating that the detection content is measured / discriminated in addition to the detection.

In the embodiment of the present invention, it is assumed that the underwater acoustic sensor 10 includes a plurality of acoustic sensors (microphones). As a result, the orientation of the sound source can be specified with reference to the installation position of the underwater acoustic sensor 10 based on the sound detection results of each of the plurality of acoustic sensors. Here, the specific configuration of the underwater acoustic sensor 10 is not limited. Hereinafter, a configuration example of the underwater acoustic sensor 10 will be described.

FIG. 2 is a diagram showing a configuration example of the underwater acoustic sensor 10. Referring to FIG. 2, the underwater acoustic sensor 12 as an example of the underwater acoustic sensor 10 has a transmission buoy unit 170, a weight 181 and a float 182, a sensing unit 130, a mooring unit 150, and a power supply unit in this order from the top. It includes 140 and a weight portion 160. However, the order of each of these configurations is not limited to the example shown in FIG. Further, an antenna unit 110, a searchlight unit 121, an anchoring light unit 122, and a solar cell 123 are provided at a position above the sea surface in the transmission buoy unit 170.

The sensing unit 130 is an acoustic sensor that is located in water and senses underwater. The sensing unit 130 obtains sensor data (acoustic data) by such sensing. The transmission buoy unit 170 receives buoyancy to the extent that the antenna unit 110 is located above the sea surface. The antenna unit 110 transmits the sensor data transmitted from the sensing unit 130 via the cable and the sensor state information of the underwater acoustic sensor 12 to the server 20 by wireless communication.

The weight 181 and the float 182 move the transmission buoy unit 170 near the sea surface to a certain extent by bending or extending the rope (including the cable) connecting the sensing unit 130 and the transmission buoy unit 170. Allow that. The mooring unit 150 connects the underwater acoustic sensor 12 (excluding the power supply unit 140 and the weight unit 160) to the power supply unit 140. As a result, the underwater acoustic sensor 12 sinks to the seabed. The power supply unit 140 supplies electric power to the antenna unit 110, the sensing unit 130, the searchlight unit 121, and the mooring light unit 122.

For example, the power supply unit 140 automatically stops providing electric power during the operating hours (for example, between 9:00:00 and 15:00:00 when fishing is performed) by the timer function, and other than the operating hours. (For example, between 15:00:01 and 8:59:59 when fishing is not carried out), the power supply may be automatically started. As a result, it is possible to prevent a legitimate ship, a legitimate diver (diver), or the like from being erroneously detected as a detection target.

As will be described later, if the underwater acoustic sensor 12 has a position detection function (for example, a position detection function by GPS (Global Positioning System)), the underwater acoustic sensor 12 obtained by this position detection function The position may be transmitted from the underwater acoustic sensor 12 to the server 20. For example, the position of the underwater acoustic sensor 12 may be transmitted from the underwater acoustic sensor 12 to the server 20 at predetermined time intervals (for example, every second). Further, the position of the underwater acoustic sensor 12 may be transmitted from the underwater acoustic sensor 12 to the server 20 on a regular basis (for example, every hour) even during the operating hours. At this time, the GPS antenna may be provided at the lower part of the antenna portion 110 as an example, but the position where the GPS antenna is provided is not limited.

The mooring portion 150 connects the underwater acoustic sensor 12 (excluding the weight portion 160) to the weight portion 160. As a result, the underwater acoustic sensor 12 sinks to the seabed. The weight portion 160 is an object having a weight sufficient to be located on the seabed, and sinks into the seabed, and the underwater acoustic sensor 12 (excluding the power supply portion 140 and the weight portion 160) is positioned within a predetermined range via the mooring portion 150. It suffices as long as it is an object that can be fastened to.

The searchlight unit 121 brightens the surroundings by irradiating the surroundings with light. Since poaching is likely to occur in a dark environment, it is expected that poaching will be suppressed by brightening the surroundings by the searchlight unit 121. Here, the searchlight unit 121 may irradiate light at a predetermined time, may irradiate light periodically, or may irradiate light randomly (randomly) at an arbitrary timing. Then, when the sensing unit 130 obtains the sensor data (acoustic data), it may irradiate the light, or may irradiate the light based on the instruction from the server 20.

The mooring light unit 122 alerts the collision prevention by turning on or blinking the warning light. It is expected that the collision prevention warning by the mooring light unit will suppress the collision of a regular ship or a poaching ship with the underwater acoustic sensor 10. The mooring light unit 122 may be supplied with electric power from the power supply unit 140, or may be supplied with electric power from the solar cell 123 or the like.

[Server 20]
The explanation will be continued by returning to FIG. Subsequently, an example of the functional configuration of the server 20 according to the embodiment of the present invention will be described. FIG. 3 is a diagram showing a functional configuration example of the server 20 according to the embodiment of the present invention. As shown in FIG. 3, the server 20 according to the embodiment of the present invention includes a control unit 220, a storage unit 230, and a communication unit 240. The control unit 220 includes an object detection unit 221 and a detection notification unit 222, a request acquisition unit 223, a data acquisition unit 224, and a data provision unit 225.

[Communication unit 240]
The communication unit 240 is composed of a communication interface and communicates with the underwater acoustic sensor 10. For example, the communication unit 240 communicates with the underwater acoustic sensor 10 via a mobile network such as an LTE network. Further, the communication unit 240 communicates with the observer terminal 30. For example, the communication unit 240 communicates with the monitor terminal 30 via a mobile network such as an LTE network. Alternatively, the communication unit 240 may communicate with the monitor terminal 30 by wire.

[Storage 230]
The storage unit 230 is a storage device capable of storing programs and data for operating the control unit 220. In addition, the storage unit 230 can temporarily store various data required in the process of operation of the control unit 220. For example, the storage device may be a non-volatile storage device. For example, the storage unit 230 may store the sensor information 231 and the notification destination information 232 as examples of various data. Hereinafter, the sensor information 231 will be described with reference to FIG. 4, and the notification destination information 232 will be described with reference to FIG.

[Sensor information 231]
FIG. 4 is a diagram showing an example of sensor information 231. As shown in FIG. 4, the sensor information 231 includes "sensor ID", "installation position information", "sensor status information", "sensor data", "weather information", and "contact name". Is associated with and is configured.

The "sensor ID" is information for uniquely identifying the underwater acoustic sensor 10.

The "installation position information" is information indicating the position where the underwater acoustic sensor 10 is installed. In the embodiment of the present invention, it is mainly assumed that the installation position information is represented by latitude and longitude. However, the expression format of the installation position information is not limited. For example, the installation position information may be expressed in polar coordinate format. For example, the installation position information may be manually input, but if the underwater acoustic sensor 10 has a position detection function for detecting its own position, the installation position information can be the installation position detected by the underwater acoustic sensor 10. It may be set based on. Further, as described above, when the position of the underwater acoustic sensor 10 is transmitted from the underwater acoustic sensor 10 to the server 20 at predetermined time intervals, the server 20 is the position of the underwater acoustic sensor 10 received from the underwater acoustic sensor 10. The installation position information may be updated at predetermined time intervals based on the above.

The "sensor state information" and "sensor data" are registered in the sensor information 231 when received from the underwater acoustic sensor 10. If the "sensor ID" is attached to the "sensor status information" and "sensor data" received from the underwater acoustic sensor 10, the "sensor ID" is the same as the "sensor ID" received from the underwater acoustic sensor 10. The associated "sensor status information" and "sensor data" are registered in the sensor information 231.

The "weather information" is information on the weather according to the installation position of the underwater acoustic sensor 10. Meteorological information may be obtained in any way. For example, weather information corresponding to the installation position of the underwater acoustic sensor 10 may be periodically acquired from a predetermined Web page and registered in the sensor information 231. The weather according to the installation position of the underwater acoustic sensor 10 may be the weather of the installation position of the underwater acoustic sensor 10 itself, or a place away from the installation position of the underwater acoustic sensor 10 (for example, the underwater acoustic sensor 10 is installed). It may be the weather of the area under the jurisdiction of the sea area. In the embodiment of the present invention, it is assumed that the meteorological information includes weather (for example, wind strength, weather, etc.), temperature, humidity, precipitation, wind speed, and the like. The weather is expected to be sunny, cloudy, rainy and snowy, and approaching a typhoon. For example, if the weather indicates that a typhoon is approaching, but the detection of a poacher or a poaching vessel is notified (because it may be difficult to poach while the typhoon is approaching). Notifications of the detection of poachers or poachers can be determined to be false alarms. However, what kind of information the meteorological information includes is not particularly limited.

The "contact name" corresponds to the name of the contact (the observer who should be contacted) corresponding to the underwater acoustic sensor 10. For example, the underwater acoustic sensor 10 installed in the area (area) that the observer wants to monitor may be selected in advance using the observer terminal 30. As a result, the name of the observer is associated with the "sensor ID" of the underwater acoustic sensor 10 selected by the observer as the "contact name".

In the example shown in FIG. 4, the sensor 1 and the sensor 2 are installed in the same area, and the sensor 3 is installed in an area different from the area where the sensor 1 and the sensor 2 are installed. It is assumed that the case is. At this time, "Mr. A" and "Mr. B" correspond to persons who intend to monitor only a specific area (for example, a specific fishery cooperative). "Mr. C" corresponds to a person who intends to monitor multiple areas (for example, the National Federation of Fisheries Associations).

[Notification destination information 232]
FIG. 5 is a diagram showing an example of notification destination information 232. As shown in FIG. 5, the notification contact information 232 is configured by associating a "contact name", a "notification address", and a "contact telephone number". For example, the notification destination information 232 may be preset by the observer using the observer terminal 30.

The "contact name" corresponds to the name of the contact (the observer who should be contacted) corresponding to the underwater acoustic sensor 10 as well as the "contact name" of the sensor information 231.

The "notification destination address" is an address indicating the notification destination of the detection when the detection target is detected by the underwater acoustic sensor 10. In the embodiment of the present invention, it is assumed that the detection notification means is an e-mail (detection mail). That is, it is mainly assumed that an e-mail address is used as the "notification destination address". However, the "notification address" is not limited to the e-mail address.

For example, as will be described later, since the detection notification needs to include a character string, the detection notification means may be any means capable of sending the character string. For example, the detection notification means may be a predetermined application capable of transmitting a character string. For example, if the notification means of detection is an SNS (Social Networking Service) application, the notification destination address may be an SNS account. Alternatively, for example, if the detection notification means is a short mail, the notification destination address may be a telephone number.

The "contact telephone number" corresponds to the telephone number of the contact (the observer who should be contacted) corresponding to the underwater acoustic sensor 10.

[Control unit 220]
The control unit 220 includes an arithmetic unit such as a CPU (Central Processing Unit), and its function is realized by expanding a program stored in a ROM (Read Only Memory) into a RAM by the arithmetic unit and executing the program. obtain. At this time, a computer-readable recording medium on which the program is recorded may also be provided. Alternatively, these blocks may be composed of dedicated hardware or may be composed of a combination of a plurality of hardware. The data required for the calculation by the arithmetic unit is appropriately stored by the storage unit 230.

The object detection unit 221 and the detection notification unit 222, the request acquisition unit 223, the data acquisition unit 224, and the data provision unit 225 will be described in detail later.

[Input unit 310]
The input unit 310 accepts an operation by the observer. In the embodiment of the present invention, it is mainly assumed that the input unit 310 is a touch panel. However, the type of the input unit 310 is not limited. For example, the input unit 310 may include a keyboard, a mouse, an electronic pen, or another input device.

[Control unit 320]
The control unit 320 includes a CPU and the like, and its function can be realized by the program stored in the storage unit 330 being expanded and executed in the RAM by the CPU. At this time, a computer-readable recording medium on which the program is recorded may also be provided. Alternatively, the control unit 320 may be configured by dedicated hardware, or may be configured by a combination of a plurality of hardware. The data required for the calculation by the arithmetic unit is appropriately stored by the storage unit 330.

[Display unit 350]
The display unit 350 has a function of displaying according to the control by the control unit 320. Here, the form of the display unit 350 is not particularly limited. For example, the display unit 350 may be a CRT (Cathode Ray Tube) display device, a liquid crystal display (LCD) device, an OLED (Organic Light Emitting Diode) device, or a display unit 350. It may be a display device such as a lamp.

[Object detection unit 221]
The explanation will be continued by returning to FIG. The object detection unit 221 detects an object to be detected based on the sensor data (acoustic data) obtained by the underwater acoustic sensor 10. As described above, the sample object is not particularly limited, but in the embodiment of the present invention, it is assumed that the object detection unit 221 detects at least one of a poaching boat and a poaching fisher as a detection target. ..

Here, the detection target may be detected in any way. For example, it is assumed that the sound emitted by the detection target has a sound characteristic for each detection target. For example, it is assumed that the characteristic of sound is the frequency of sound. Therefore, when the object detection unit 221 detects a sound having a predetermined frequency, the object detection unit 221 may detect the sound as a sound emitted by the detection object.

For example, it is known that the mechanical noise generated by the engine rotation generated by the ship and the draining sound generated by the screw rotation generated by the ship have a frequency lower than a certain frequency (first frequency) and are continuously emitted for a predetermined time. Has been done. Therefore, even if the object detection unit 221 continuously detects a sound having a frequency lower than the first frequency for a longer time than a predetermined time, the object detection unit 221 detects the sound as a sound emitted by a poaching boat. good.

For example, the sensing unit 130 of the underwater acoustic sensor 10 includes a first acoustic sensor (hereinafter, also referred to as “low frequency acoustic sensor”) capable of detecting a sound having a frequency lower than the first frequency. If so, the low frequency acoustic sensor can sense sound having a frequency lower than the first frequency.

On the other hand, it is known that the sound of air passing through a regulator (regulator) when a diver sucks air from a cylinder has a frequency higher than a certain frequency (second frequency). Therefore, when the object detection unit 221 detects a sound having a frequency higher than the second frequency, the object detection unit 221 may detect the sound as a sound emitted by a poacher.

For example, the sensing unit 130 of the underwater acoustic sensor 10 includes a second acoustic sensor (hereinafter, also referred to as "acoustic sensor for high frequency") capable of detecting a sound having a frequency higher than the second frequency. For example, a sound having a frequency higher than the second frequency can be sensed by an acoustic sensor for high frequency.

It should be noted that there may be a single underwater sound similar to the sound of air passing through a regulator. In such a case, it may be erroneously detected that a poacher has been detected based on the sensing of similar underwater sounds. Therefore, when the object detection unit 221 detects a frequency higher than the second frequency a plurality of times within a designated time, the object detection unit 221 may detect the sound as a sound emitted by a poacher.

Here, the first frequency and the second frequency may be included in a frequency of approximately 20 to 20 kHz (audible range). In this case, the first frequency and the second frequency are audible sounds (sound waves having a frequency of approximately 20 to 20 kHz). Specifically, for example, the first frequency may be 2 kHz. In this case, when the sound of, for example, 1 kHz (frequency lower than the first frequency) is sensed by the underwater acoustic sensor 10, the object detection unit 221 may detect it as the sound emitted by the poaching boat. Specifically, for example, the second frequency may be 9 kHz. In this case, when the underwater acoustic sensor 10 senses a sound of, for example, 10 kHz (a frequency higher than the second frequency), the object detection unit 221 may detect it as a sound emitted by a poacher.

As described above, when the object detection unit 221 continuously detects a sound having a frequency lower than the first frequency for a longer time than a predetermined time, the sound is used as a sound emitted by a poaching boat. Apart from the mode of detecting or detecting a sound having a frequency higher than the second frequency as a sound emitted by a poacher, a predetermined frequency or a predetermined frequency ± 100 Hz frequency. When a sound having is detected, it may be detected. For example, the object detection unit 221 may detect a sound of 1 kHz or 1 kHz ± 100 Hz as a sound emitted by a poaching boat when the sound of 1 kHz or 1 kHz ± 100 Hz is sensed by the underwater acoustic sensor 10. For example, the object detection unit 221 may detect a sound of 10 kHz or 10 kHz ± 100 Hz as a sound emitted by a poacher when the sound of 10 kHz or 10 kHz ± 100 Hz is sensed by the underwater acoustic sensor 10.

Further, as described above, the object detection unit 221 can specify the direction of the sound source (that is, the detection object) based on the installation position of the underwater acoustic sensor 10 based on the sensor data. The object detection unit 221 determines the orientation of the detection object based on the installation position of the underwater acoustic sensor 10, the type of the detection object (that is, whether it is a poaching boat or a poacher), and the detection target. The detected sensor ID of the underwater acoustic sensor 10 is output to the detection notification unit 222.

It is also assumed that the same object to be detected may be detected by a plurality of underwater acoustic sensors 10 at the same time. In such a case, the object detection unit 221 can specify the orientation of the detection object with reference to each of the installation positions of the plurality of underwater acoustic sensors 10. At this time, the object detection unit 221 positions the detection target based on the orientation of the detection target based on each of the installation positions of the plurality of underwater acoustic sensors 10 and the installation positions of the plurality of underwater acoustic sensors 10. (Latitude and longitude) can be specified. In such a case, the object detection unit 221 detects the position of the detection target, the type of the detection target, and the sensor IDs of the plurality of underwater acoustic sensors 10 in which the detection target is detected. It should be output to.

In the embodiment of the present invention, it is mainly assumed that the object detection unit 221 exists in the server 20. However, if an analyzer (not shown) exists between the underwater acoustic sensor 10 and the server 20, the object detection unit 221 may be incorporated in the analyzer. In such a case, the analyzer receives the sensor data obtained by the underwater acoustic sensor 10. Then, when the analyzer detects the detection target based on the acquired sensor data, the orientation of the detection target based on the installation position of the underwater acoustic sensor 10, the type of the detection target, and the detection target are determined. The detected sensor ID of the underwater acoustic sensor 10 may be transmitted to the server 20.

[Detection notification unit 222]
When the object detection unit 221 detects the detection object, the detection notification unit 222 sets the identification information corresponding to the detection information and the type of the detection object to the underwater acoustic sensor prior to the detection information itself. Transmission to the observer terminal 30 previously associated with 10 (more specifically, in the sensor information 231, the observer terminal 30 indicated by the "notification destination address" associated with the "sensor ID" of the underwater acoustic sensor 10). The communication unit 240 is controlled so as to be performed. As a result, the observer terminal 30 is notified of the detection of the detection target object.

In the following, it is assumed that the identification information is a URL (Uniform Resource Identifier) indicating the location of the information related to detection. The URL indicating the location of the information related to detection is formed based on the document RFC (Request For Commission) (for example, RFC 2396 or RFC 3896) issued by the IETF (Internet Engineering Task Force), which is an organization that sets the standard of technology related to the Internet. May be good. For example, RFC3986 indicates that it consists of a hierarchical sequence of components called Scheme, authority, path, query and fragment as a general URI (Uniform Resource Identifier) syntax, and indicates that it consists of a hierarchical sequence of components called "URI = scheme": "here-part [". "? It is indicated as "quarry" ["#" fragment] ". The URL indicating the location of the information related to the detection is, for example, "https://sensor.server.jp/poaching/999". The URL "https://user.server.jp/poaching/999" indicating the location of information related to detection is an identification information (scheme name) "https" representing a scheme (scheme), and an HTTP (HyperText Transfer Protocol) server (server). 20) Identification information (host name) "sensor.server.jp" representing an address and identification information "/poaching/999" representing a path ("999" is identification information representing a program or Web page that provides information on detection). It is composed of. However, the identification information is not limited to the URL as long as the information related to the detection can be identified. For example, the identification information may be characters or images corresponding to the URL indicating the location of the information related to detection. In this case, the characters and images corresponding to the URL indicating the location of the information related to detection may be characters and images different from the URL indicating the location of the information related to detection.

As described above, the detection notification means is not limited, but when the detection is notified by the detection mail (e-mail), the detection notification unit 222 includes the character string of the URL indicating the location of the information related to the detection in the text. It suffices to control so that the mail is transmitted to the observer terminal 30. Further, when the detection is notified by the detection mail (HTML e-mail), the detection notification unit 222 sends the detection mail including characters and images corresponding to the URL indicating the location of the information related to the detection to the monitor terminal 30. It suffices to control so that it is transmitted. A specific example of information related to detection will be described later.

[Detection mail]
FIG. 7 is a diagram showing an example of a detection email. As shown in FIG. 7, the detection email G10 includes a sender, a subject, a transmission date and time (of the detection email), a destination (of the detection email), and a body. In the text, "mitsuryosen" and "mitsuryosen" are described as examples of the types of objects to be detected. In addition, a URL (B10) (https://sensor.server.jp/poaching/999) indicating the location of information related to detection is described. In the observer terminal 30, when the detection mail G10 is received by the communication unit 340, the control unit 320 controls the display unit 350 so that the detection mail G10 is displayed by the display unit 350. The observer terminal 30 (control unit 320) may be controlled to automatically display the detection email G10 when the detection email G10 is received, or the detection email G10 may be controlled according to the operation of the observer. May be controlled to display.

The observer performs a URL (B10) selection operation on the input unit 310 at a timing when he / she wants to confirm the information related to the detection. For example, when the input unit 310 includes a touch panel, the selection operation may be a tap operation on the touch panel. Alternatively, when the input unit 310 includes a mouse, the selection operation may be a click operation using the mouse. In addition, the selection operation may be appropriately changed according to the type of the input unit 310. If the URL (B10) indicating the location of the information related to detection is a character or image corresponding to the URL indicating the location of the information related to detection, the observer detects it at the timing when he / she wants to confirm the information related to detection. The input unit 310 is subjected to a selection operation of characters, images, and the like corresponding to the URL indicating the location of the information related to the information.

When the input unit 310 accepts the URL selection operation (selection operation of characters, images, etc. corresponding to the URL), the control unit 320 sends a data transmission request corresponding to the URL (characters, images, etc. corresponding to the URL) to the server. The communication unit 340 is controlled so as to be transmitted to 20. For example, the control unit 320 includes a GET method (character "GET") and a request target "https://sensor.server.jp/poaching/999" (character) in the request line as a data transmission request (HTTP message). The communication unit 340 is controlled so that the GET request of the HTTP to be sent to the server 20 is transmitted. Here, the request target "https://sensor.server.jp/poaching/999" in the data transmission request is a URL (B10) indicating the location of information related to detection included in the detection mail G10.

If the observer contacts another person by some contact function (for example, telephone function, mail function, etc.) on the observer terminal 30 within a predetermined time after the observer performs the selection operation, the observer will contact the person. The name (contact name) of the other person and the contact information (notification address and / or contact telephone number) of the other person may be notified from the monitor terminal 30 to the server 20. At this time, the server 20 newly registers the name of the other person notified from the observer terminal 30 as the "contact name" in the sensor information 231 (FIG. 4), and the server 20 newly registers the name of the other person notified from the observer terminal 30. The name and the contact information of the other person may be newly registered in the notification information 232 (FIG. 5) as the "contact name" and "notification address (and contact telephone number)". Then, in addition to the observer, the server 20 may send the detection mail G10 to the other person based on the newly registered contact information of the other person. By newly registering the notification destination information 232 (FIG. 5), the server 20 can resend the detection mail G10 sent to the monitor terminal 30 to the notification destination address of the other person, and the monitor When the detection mail G10 is newly sent to the terminal 30, the notification destination address of the other person can be included.

[Request acquisition unit 223]
The explanation will be continued by returning to FIG. When the communication unit 240 receives the data transmission request corresponding to the URL from the monitor terminal 30 in the server 20, the request acquisition unit 223 acquires the data acquisition request corresponding to the URL from the communication unit 240.

[Data acquisition unit 224]
When the data transmission request corresponding to the URL is acquired by the request acquisition unit 223, the data acquisition unit 224 acquires the information regarding the detection corresponding to the URL. In the embodiment of the present invention, it is assumed that the information regarding the detection includes a map corresponding to the installation position of the underwater acoustic sensor 10 in which the detection target is detected.

In the embodiment of the present invention, it is mainly assumed that the data acquisition unit 224 acquires a map from a predetermined map providing API (Application Programming Interface). In such a case, if the data acquisition unit 224 notifies the map providing API of the reference point of the map to be acquired and the range (for example, zoom) of the map centered on the reference point, the reference point is set as the center. A map of the range can be obtained from the map provided API.

Therefore, the map providing API is a specification of an interface for the map providing program to manage and provide the map information and the data acquisition unit 224 to exchange with each other, and the map providing program and the data acquisition unit 224 to provide the map information. It is a program that intervenes between. The map providing API may be inherent in the map providing program, or may exist as a program different from the map providing program.

Further, the map providing program and the map providing API may be arranged on the server 20 or may be arranged on an external server other than the server 20. When the map providing program and the map providing API are distributed to the server 20, map information is stored in the storage unit 230, and the data acquisition unit 224 can acquire a map from the storage unit 230 via the map providing API. When the map providing program and the map providing API are distributed to an external server other than the server 20, the map information is stored in the external server, and the data acquisition unit 224 is an external server via the network and the map providing API. You can get the map from.

For example, when the map providing program and the map providing API are arranged on an external HTTP server other than the server 20, and the data acquisition unit 224 acquires a map from a predetermined map providing API, HTTP can be used. In this case, since the external HTTP server is a map providing server that manages map information and provides a map over a network based on the HTTP communication protocol, the map providing API is paraphrased as a map providing WebAPI (map providing Web service). You may.

FIG. 8 shows an example of the request target of the data transmission request (HTTP message) used when acquiring the map from the map providing WebAPI “http://192.168.10.10/map1.asp?position=43.856644, 141.5393337 & map = + 2 & size = 300x300 ”. As shown in FIG. 8, the request target of the data transmission request (HTTP message) represents, for example, the identification information (scheme name) “http” representing the scheme (scheme) and the address of the map providing server (external HTTP server). Identification information (host name) "192.168.10.10", identification information "map1.asp" indicating the name of the map providing program, location information "position = 43.8566444, 141.5393337" (latitude, longitude), It is composed of enlargement / reduction control information "zoom = + 2" and identification information "size = 300x300" indicating the size of the search range.

In the case of the example shown in FIG. 8, when the data acquisition unit 224 acquires the map from the map providing WebAPI, the GET method (character "GET") and the request target "http" are added to the request line as a data transmission request (HTTP message). // 192.168.10.10/map1.asp?position=43.856644,141.5393337&zoom=+2&size=300x300 "(characters) is included in the HTTP GET request sent to the map providing server (external HTTP server). The communication unit 240 is controlled so as to be performed. The map providing server that received the GET request of HTTP has location information "position = 43.8566444, 141.5393337" (latitude, longitude), enlargement / reduction control information "zoom = +2", and identification information "zoom = +2" indicating the size of the search range. Based on "size = 300x300", the corresponding map is acquired from the map information, and the HTTP response including the acquired map is returned to the data acquisition unit 224 (server 20). In this way, the data acquisition unit 224 acquires the map from the map providing WebAPI.

Here, the reference point may be the installation position of the underwater acoustic sensor 10 associated with the observer terminal 30 in advance. At this time, it is desirable that the range of the map is determined so as to be within the detectable range of the underwater acoustic sensor 10 associated with the observer terminal 30 in advance.

Alternatively, when there are a plurality of underwater acoustic sensors 10 associated with the observer terminal 30 in advance, the reference point may be a position corresponding to the installation position of the plurality of underwater acoustic sensors 10 (for example, the position of the center of gravity). good. At this time, it is desirable that the range of the map is determined so as to include the detectable range of all the plurality of underwater acoustic sensors 10 associated with the observer terminal 30 in advance.

Alternatively, the reference point may be the installation position of the underwater acoustic sensor 10 in which the detection target is detected among the one or a plurality of underwater acoustic sensors 10 associated with the observer terminal 30 in advance. At this time, it is desirable that the range of the map is determined so that the detectable range of the underwater acoustic sensor 10 in which the detection target is detected falls within.

Further, in the embodiment of the present invention, it is assumed that the information related to the detection includes additional information other than the map. However, the information regarding detection may include at least one of a map and additional information.

In the embodiment of the present invention, it is assumed that the additional information includes a contact name and a contact telephone number (FIG. 5) previously associated with the underwater acoustic sensor 10 in which the detection target is detected. Since the contact name and contact phone number are examples of information about the notification destination, information about other notification destinations (for example, notification address) is added instead of the notification name and contact phone number. It may be included in the information.

Further, in the embodiment of the present invention, it is assumed that the additional information includes the sensor state information (FIG. 4) of the underwater acoustic sensor 10 in which the detection target is detected. Further, in the embodiment of the present invention, it is assumed that the additional information includes the weather information corresponding to the installation position of the underwater acoustic sensor 10 in which the detection target is detected.

Further, in the embodiment of the present invention, it is assumed that the additional information includes the detection mail transmission date and time (detection mail transmission date and detection mail transmission time) to the monitor terminal 30. However, the additional information is added to the detection date and time of the detection target object instead of the detection mail transmission date and time to the monitor terminal 30 or to the detection mail transmission date and time to the monitor terminal 30 (detection date and time of the detection target object). And the detection time of the object to be detected).

[Data provision unit 225]
The data providing unit 225 controls the communication unit 240 so that the information regarding the detection is transmitted to the monitor terminal 30. For example, the data providing unit 225 controls the communication unit 240 so that the HTTP response including the information related to the detection is returned to the monitor terminal 30 as a response to the HTTP GET request.

[Detection screen]
In the observer terminal 30, when the communication unit 340 receives the information related to the detection, the control unit 320 acquires the information related to the detection. The control unit 320 controls the display unit 350 so that the detection screen is displayed by the display unit 350 based on the information related to the detection. The observer can grasp the information related to the detection by looking at the detection screen displayed by the display unit 350. Hereinafter, an example of the detection screen will be described with reference to FIGS. 9 to 16.

FIG. 9 is a diagram showing an example of a detection screen G20 when an object to be detected is detected by one underwater acoustic sensor 10. Referring to FIG. 9, the detection screen G20 includes an area where a map is displayed (map display area W21) and an area where additional information is displayed (additional information display area W22). With reference to the map display area W21, an object (sensor) indicating the sensor at a position on the map (sensor position on the map) corresponding to the installation position of the underwater acoustic sensor 10 in which the detection target is detected by the data acquisition unit 224. Object B211) is added.

Here, it is assumed that the underwater acoustic sensor 10 includes both a high-frequency acoustic sensor and a low-frequency acoustic sensor. With reference to the map display area W21, the data acquisition unit 224 refers to an object (poaching) based on the sensor position on the map in the direction on the map corresponding to the poacher's orientation (detected by the acoustic sensor for high frequency). A person detection direction object D211) is attached. Further, referring to the map display area W21, the data acquisition unit 224 uses the sensor position on the map as a reference in the direction on the map corresponding to the orientation of the poaching boat (detected by the low frequency acoustic sensor). An object (Mitsuryosen detection direction object D212) is attached.

In the example shown in FIG. 9, the poacher detection direction object D211 and the poaching boat detection direction object D212 are distinguished by the difference in color and size, but the poacher detection direction object D211 and the poaching boat The detection direction object D212 may be distinguished from the detection direction object D212 by another aspect. For example, the poacher detection direction object D211 and the poacher detection direction object D212 may be distinguished by the difference in shape.

Further, in the example shown in FIG. 9, the shapes of the poacher detection direction object D211 and the poacher detection direction object D212 are fan-shaped, but the shapes of the poacher detection direction object D211 and the poacher detection direction object D212 are respectively. Is not limited. For example, the shape of each of the poacher detection direction object D211 and the poacher detection direction object D212 may be a triangle whose apex is located at the sensor position on the map.

With reference to FIG. 9, the fan-shaped radius of the poaching boat detection direction object D212 is larger than the fan-shaped radius of the poacher detection direction object D211. This is because the radius of each sector reflects the magnitude of the detectable range of the acoustic sensor (ie, the lower frequency for poaching boat detection than the high frequency acoustic sensor for poacher detection). The acoustic sensor for is wider in the detectable range). Here, as an example, the detectable range of the high-frequency acoustic sensor (hereinafter, also referred to as “high-frequency detection range”) is 500 m in radius, and the detectable range of the low-frequency acoustic sensor (hereinafter, “low-frequency detection range””). Also called) is assumed to have a radius of 1000 m.

Further, referring to the map display area W21, the map includes an object for adjusting the display size of the map (display size adjustment object D272). As a result, the observer inputs the enlargement operation or the reduction operation to the input unit 310 using the display size adjustment object D272, so that the enlarged or reduced map is provided from the server 20 to the observer terminal 30, and the display unit. A new map after enlargement or reduction is displayed by 350.

Further, referring to the map display area W21, the map includes a width on the map corresponding to the width in the real space as a scale bar. "100m" is displayed as an example of the width in the real space. By checking the scale bar, the observer can grasp the correspondence between the width on the map and the width in the real space. In addition, referring to the map display area W21, a display switching object B210 is added to the map by the data acquisition unit 224. The display switching object B210 will be described later.

The additional information display area W22 includes a "last updated date and time" indicating the date and time when the map was last updated. Further, the additional information display area W22 includes "state: poaching is being detected" indicating the state of the system. Further, the additional information display area W22 includes an additional information display switching button B221. The additional information display switching button B221 will be described later. In addition, the additional information display area W22 includes the "detection mail transmission date and time", but as described above, instead of the "detection mail transmission date and time" or by adding it to the "detection mail transmission date and time". , The detection date and time of the detection object may be included.

Further, the additional information display area W22 includes a clear button B222. The observer can make the server 20 clear the detection mail transmission date and time by inputting the selection operation of the clear button B222 into the input unit 310. Once the detection email is transmitted to the monitor terminal 30, the detection email is not usually transmitted to the monitor terminal 30 even if the detection target is detected again for a certain period of time. However, after the clear button B222 is selected, the detection mail is transmitted to the monitor terminal 30 at the timing when the detection target is detected again even if a certain time has not elapsed.

In addition, the additional information display area W22 includes a "contact list". The "contact list" is a list of contact names and contact telephone numbers (FIG. 5) associated with the underwater acoustic sensor 10 in which the detection target is detected in advance. However, as mentioned above, the contact name and contact phone number are examples of information about the notification destination, so instead of the notification name and contact phone number, other notification destinations (eg, security companies and police) Information related to (for example, notification destination address, etc.) may be included in the additional information display area W22.

Here, switching between display and non-display of each of the range on the map corresponding to the high frequency detection range and the range on the map corresponding to the low frequency detection range is a predetermined operation by the observer (hereinafter, hereafter. It may be possible by (also referred to as "detection range display switching operation"). For example, the detection range display switching operation may be a selection operation of the sensor object B211. Alternatively, an object for performing the detection range display switching operation may be provided separately from the sensor object B211.

FIG. 10 is a diagram showing an example of a range on a map corresponding to a detection range. In the example shown in FIG. 10, it is assumed that the observer inputs the selection operation of the sensor object B211 to the input unit 310 as an example of the detection range display switching operation. In such a case, the data acquisition unit 224 attaches the range D213 on the map corresponding to the high frequency detection range and the range D214 on the map corresponding to the low frequency detection range to the map, and the display unit 350 displays the range D214. .. When the detection range display switching operation is input again, the range D213 on the map corresponding to the high frequency detection range and the range D214 on the map corresponding to the low frequency detection range may be hidden. ..

FIG. 11 is a diagram showing an example when a selection operation of the display switching object B210 is input. The display switching object B210 is an object for switching between display and non-display of information regarding the underwater acoustic sensor 10. The display switching object B210 is added to the map by the data acquisition unit 224.

In the example shown in FIG. 11, the sensor name D217 of the underwater acoustic sensor 10 is added to the map as an example of information regarding the underwater acoustic sensor 10. In addition, as an example of information on the underwater acoustic sensor 10, information on the acoustic sensor that detected the poacher D215 (“detection time” of the poacher, “direction” of the poacher based on the sensor, “radius” of the high frequency detection range ) And information D216 about the acoustic sensor that detected the mitsuryosen (“detection time” of the mitsuryosen, “direction” of the mitsuryosen based on the sensor, “radius” of the low frequency detection range) are added to the map. There is.

When the deselection of the display switching object B210 is input, the sensor name D217, the information D215 regarding the acoustic sensor that detects the poacher, and the information D216 about the acoustic sensor that detects the poacher are hidden. It's okay.

FIG. 12 is a diagram showing an example when the additional information display area W22 is scrolled. Here, it is assumed that the observer inputs the downward scroll operation of the additional information display area W22 to the input unit 310. At this time, the additional information display area W22 includes "weather information" and "map legend".

In the "map legend", the description regarding the change of the aspect of the sensor object B211 according to the sensor state information is described. Here, a case where the shape of the sensor object B211 changes according to the sensor state information is shown. However, the method of changing the mode of the sensor object B211 according to the sensor state information by the data acquisition unit 224 is not limited to such an example. For example, the color of the sensor object B211 may change according to the sensor state information. Alternatively, text data indicating the sensor state information may be added to the sensor object B211 (for example, as a balloon).

FIG. 13 is a diagram showing an example when the selection operation of the additional information display switching button B221 is input. Here, it is assumed that the observer inputs the selection operation of the additional information display switching button B221 to the input unit 310. At this time, the additional information display area W22 is hidden by the data acquisition unit 224. As a result, the map is displayed in a wider range (the map display area W21 is wider). With reference to FIG. 13, the detection screen G20 includes an additional information display switching button B223.

The communication unit 340 is controlled so as to be transmitted to (S33).

In the server 20, when the map display request is received by the communication unit 240 (S25), the request acquisition unit 223 acquires the map display request. When the data acquisition unit 224 acquires the map (and additional information) corresponding to the URL, the data acquisition unit 224 controls the communication unit 240 so that the acquired map (and additional information) is transmitted to the monitor terminal 30 (S26). In the observer terminal 30, when the map (and additional information) is received by the communication unit 340 (S34), the map (and additional information) is displayed by the display unit 350 (S35). S34 and S35 may be repeatedly executed at predetermined time intervals.
