[0012] 1. First embodiment (1) System Overview The system 100 will be described below. The system 100 is a system for acquiring various sensor information in an area (called the predetermined area A) used by many people, such as a certain predetermined area, an urban area in the predetermined area, or a shopping district, and / or for amplifying predetermined sounds toward the predetermined area A. The system 100 can provide various services based on the acquired sensor information, and amplifying services for the entire predetermined area A or specific locations or areas of the predetermined area A. Specific examples of these services will be described in detail later.

[0013] (2) System Configuration The configuration of the system 100 will be described with reference to Fig. 1. Fig. 1 is a diagram showing the configuration of the system 100. The system 100 includes a plurality of loudspeaker sensor devices 10 and a server 20.

[0014] A plurality of loudspeaker sensor devices 10 are provided in a predetermined area A where it is desired to amplify sound and / or acquire various sensor information, and amplify a predetermined sound toward the predetermined area A and / or acquire various sensor information related to the predetermined area A. As will be described later, the loudspeaker sensor device 10 is a system that integrates a sensor device 11 that acquires sensor information and a loudspeaker device 13 that amplifies sound.

[0015] The multiple loudspeaker sensor devices 10 are installed using public infrastructure facilities present in a predetermined area A. Specifically, the multiple loudspeaker sensor devices 10 are installed on at least some of the multiple utility poles P provided in the predetermined area A and / or on at least some of the overhead lines L installed by being hung on the multiple utility poles P. The overhead lines L are, for example, power lines for supplying power and communication lines for wired communication.

[0016] More specifically, as shown in Fig. 2, one loudspeaker sensor device 10 is provided on each of all or some of a plurality of utility poles P, and one loudspeaker sensor device 10 is provided on each of all or some of the overhead wires L stretched between two utility poles P. Fig. 2 shows an example of installation of the loudspeaker sensor device 10 on the utility poles P and the overhead wires L.

[0017] A public infrastructure facility having a plurality of utility poles P and overhead lines L strung across the plurality of utility poles P is installed throughout a predetermined area A in order to provide power and communications to all buildings, factories, houses, etc. present in the predetermined area A. The utility poles P are installed, for example, along roads in the predetermined area A, and the overhead lines L are installed along the installation direction of the plurality of utility poles P (i.e., the roads) and are strung from the utility poles P to the buildings, factories, houses, etc.

[0018] Therefore, by installing the loudspeaker sensor devices 10 on utility poles P and / or overhead wires L installed in the predetermined area A, a plurality of loudspeaker sensor devices 10 can be installed throughout the predetermined area A. For example, as shown in Fig. 3, the loudspeaker sensor devices 10 can be installed along almost all roads in the predetermined area A. Fig. 3 is a diagram showing an example of an installation state of the loudspeaker sensor devices 10 in the predetermined area A.

[0019] In this way, by installing the loudspeaker sensor device 10 using public infrastructure facilities (i.e., utility poles P and / or overhead lines L) installed in the specified area A, there is no need to secure a large amount of installation space in the area A for installing the loudspeaker sensor device 10, and the loudspeaker sensor device 10 can be easily installed throughout the specified area A without having to install new poles or other fastening devices for fixing the loudspeaker sensor device 10.

[0020] In addition, the roads provided in the predetermined area A are the traffic lines of people and the like present in the predetermined area A. Therefore, by installing the loudspeaker sensor devices 10 along the roads provided in the predetermined area A, the system 100 can obtain sensor information on many people present in the predetermined area A and can also provide loudspeaking to many people.

[0021] Moreover, power is generally supplied to the overhead line L installed using the utility pole P. Therefore, by installing the loudspeaker sensor device 10 on the utility pole P and / or the overhead line L, the power for driving the loudspeaker sensor device 10 can be obtained from the overhead line L. In other words, the power for the loudspeaker sensor device 10 can be easily secured without installing, for example, a separate power supply facility or the like.

[0022] The loudspeaker sensor device 10 is connected to a network N. The loudspeaker sensor device 10 is capable of communicating with a server 20 via the network N. The network N is, for example, the Internet or a wide area LAN.

[0023] The server 20 is a computer system configured with a CPU, a storage device (RAM, ROM, SSD, hard disk, etc.), various interfaces (for example, communication interfaces), etc. The server 20 is connected to a network N and is capable of communicating with each of the multiple loudspeaker sensor devices 10.

[0024] The server 20 manages a plurality of loudspeaker sensor devices 10 installed in a predetermined area A. As described below, the server 20 manages the installation positions of the plurality of loudspeaker sensor devices 10. When sensor information is acquired from any of the plurality of loudspeaker sensor devices 10, the server 20 associates the sensor information with the installation position of the loudspeaker sensor device 10 (sensor device 11) that acquired the sensor information, and the time (date, time, etc.) when the sensor information was acquired by the loudspeaker sensor device 10. This makes it possible to identify at what position and when the sensor information was acquired.

[0025] Furthermore, when it is desired to amplify a sound to a specific position or partial area within the predetermined area A, the server 20 selects a loudspeaker sensor device 10 (loudspeaker device 13) installed in the specific position or partial area, and commands the selected loudspeaker device to amplify the sound. This makes it possible to amplify a sound to any position or area within the predetermined area A.

[0026] The system 100 may include a user terminal 30. The user terminal 30 is connected to a network N and is capable of communicating with the server 20. The user terminal 30 may be capable of communicating with the loudspeaker sensor device 10. The user terminal 30 is, for example, an information processing device such as a personal computer, a tablet terminal, a smartphone, or a mobile terminal. By accessing the server 20 using the user terminal 30, the user can receive various services from the server 20 via the user terminal 30.

[0027] (3) Configuration of the loudspeaker sensor device Next, the configuration of the loudspeaker sensor device 10 will be described with reference to Fig. 4. Fig. 4 is a diagram showing the configuration of the loudspeaker sensor device 10. The loudspeaker sensor device 10 has a sensor device 11, a loudspeaker device 13, and a power supply unit 15. In other words, the loudspeaker sensor device 10 is a device in which the sensor device 11 and the loudspeaker device 13 are integrated together.

[0028] The sensor device 11 acquires sensor information at the installation position of the loudspeaker sensor device 10 and transmits the acquired sensor information to the server 20. The sensor device 11 has a sensor 111, a data generating unit 113, and a first communication unit 115. The sensor 111 performs various measurements at the installation position of the loudspeaker sensor device 10. The sensor 111 is, for example, a CCD sensor that captures images of the surroundings of the installation position of the loudspeaker sensor device 10, an acoustic sensor that measures sound pressure around the installation position, and a weather sensor that acquires weather information such as temperature, humidity, wind speed, etc. around the installation position.

[0029] The data generating unit 113 is hardware (electrical circuitry) that generates sensor information from various measurement results obtained by the sensor 111. When the sensor 111 is a CCD sensor, the data generating unit 113 generates image data as sensor information from information acquired by the CCD sensor. When the sensor 111 is an acoustic sensor, the data generating unit 113 generates a sound pressure value measured by the acoustic sensor as sensor information. In addition, the data generating unit 113 generates sensor information that is audio data from audio measured by the acoustic sensor. When the sensor 111 is a weather sensor, the data generating unit 113 generates sensor information in the form of data on values ​​of temperature, humidity, wind speed, and the like detected by the weather sensor. The above functions of the data generating unit 113 may be realized by a program executable by the sensor device 11.

[0030] The first communication unit 115 is hardware (communication circuit) that communicates with other devices such as the server 20 via the network N. The first communication unit 115 transmits the sensor information generated by the data generation unit 113 to the server 20.

[0031] The loudspeaker 13 amplifies the sound around the installation position of the loudspeaker sensor device 10. The loudspeaker 13 has a speaker 131, a loudspeaker control unit 133, and a second communication unit 135. The speaker 131 converts an audio signal into a sound wave and amplifies the sound around the installation position of the loudspeaker sensor device 10. The speaker 131 may be an omnidirectional speaker or a directional speaker that has directionality toward a sidewalk or a roadway.

[0032] The loudspeaker control unit 133 is a circuit (electrical circuit) that converts audio data received from the server 20 via the second communication unit 135 into an audio signal and outputs it to the speaker 131. The above-mentioned functions of the loudspeaker control unit 133 may be realized by a program executable by the loudspeaker device 13.

[0033] The second communication unit 135 is hardware (communication circuit) that communicates with other devices such as the server 20 via the network N. The second communication unit 135 receives, from the server 20, audio data to be amplified.

[0034] The power supply unit 15 supplies power to drive the sensor device 11 and the loudspeaker 13. The power supply unit 15 of the loudspeaker sensor device 10, which is installed on an overhead line L (e.g., a power line) to which high-voltage power is supplied, can be composed of, for example, a coil that detects a magnetic field generated when a current flows through the overhead line L, and an electric circuit that converts the power generated by the coil that detected the magnetic field into power that can be used by the sensor device 11 and the loudspeaker 13.

[0035] On the other hand, the power supply unit 15 of the loudspeaker sensor device 10, which is installed on an electric pole P or an overhead line L (e.g., a communication line) to which low-voltage power is supplied, can be configured, for example, by an electric circuit that converts reduced-voltage power supplied from a voltage converter (transformer) installed on the electric pole P, or the power of the low-voltage overhead line L, into power that can be used by the sensor device 11 and the loudspeaker device 13.

[0036] The loudspeaker sensor device 10 may be provided with both a high-voltage power supply unit 15 constituted by the coil and the electric circuit, and a low-voltage power supply unit 15 constituted by the electric circuit.

[0037] (4) Server configuration The configuration of the server 20 will be described below with reference to Fig. 5. Fig. 5 is a diagram showing the configuration of the server 20. The server 20 has an information processing unit 21, a third communication unit 23, and a storage unit 25. The information processing unit 21 is configured by the CPU of the server 20 and executes various information processes related to the server 20.

[0038] Specifically, the information processing unit 21 acquires sensor information from any of the multiple loudspeaker sensor devices 10 (sensor devices 11), and associates the acquired sensor information with the installation position of the loudspeaker sensor device 10 that acquired the sensor information, and the time when the loudspeaker sensor device 10 acquired the sensor information. In other words, when the information processing unit 21 acquires sensor information, it determines at what position within a predetermined area A and when the sensor information was acquired. Furthermore, the information processing unit 21 performs various information processes using the acquired sensor information, and provides services related to the sensor information.

[0039] Furthermore, when amplifying sound, the information processing unit 21 determines which position or partial area of ​​the predetermined area A is to be amplified, and identifies the target loudspeaker sensor device 10 (loudspeaker device 13) for amplifying sound. The information processing unit 21 transmits the sound data to be amplified to the identified loudspeaker sensor device 10 (loudspeaker device 13). The above processing of the information processing unit 21 is realized by executing a program stored in the storage unit 25 of the server 20 or the like.

[0040] The third communication unit 23 is a communication interface of the server 20, and is hardware (communication circuit) that communicates with other devices such as the loudspeaker sensor device 10 via the network N. The third communication unit 23 is, for example, an Ethernet (registered trademark) card. The third communication unit 23 receives sensor information from the loudspeaker sensor device 10 (sensor device 11), and transmits voice data to be amplified by the loudspeaker sensor device 10 (loudspeaker device 13).

[0041] The storage unit 25 is configured by a storage device of the server 20, and stores various information used in the server 20, sensor information acquired from the loudspeaker sensor device 10, etc. Specifically, the storage unit 25 stores sensor device management information I1 and loudspeaker device management information I2.

[0042] The sensor device management information I1 is information for managing the sensor devices 11 installed in a predetermined area A. As shown in Fig. 6, the sensor device management information I1 has a first identification information storage column C11, a first installation position storage column C12, and a first address storage column C13. Fig. 6 is a diagram showing an example of the sensor device management information I1.

[0043] The first identification information storage column C11 stores the identification information of each of the multiple sensor devices 11. The first installation position storage column C12 stores information about the installation position of each of the multiple sensor devices 11. The information stored in the first installation position storage column C12 is associated with the identification information of the corresponding sensor device 11. In the example shown in FIG. 6, the information stored in the first installation position storage column C12 is an address (city, ward, town, village name and street address) representing the installation position. However, the present invention is not limited to this, and the information stored in the first installation position storage column C12 may be the latitude and longitude of the installation position. The first address storage column C13 stores an address (e.g., IP address, etc.) for accessing each sensor device 11 via the network N. The information stored in the first address storage column C13 is associated with the identification information of the corresponding sensor device 11 and information about the installation position of the corresponding sensor device 11.

[0044] The loudspeaker management information I2 is information for managing the loudspeakers 13 installed in a predetermined area A. As shown in Fig. 7, the loudspeaker management information I2 has a second identification information storage column C21, a second installation position storage column C22, and a second address storage column C23. Fig. 7 is a diagram showing an example of the loudspeaker management information I2.

[0045] The second identification information storage column C21 stores the identification information of each of the multiple loudspeaker devices 13. The second installation position storage column C22 stores information related to the installation position of each of the multiple loudspeaker devices 13. The information stored in the second installation position storage column C22 is associated with the identification information of the corresponding loudspeaker device 13. In the example shown in FIG. 7, the information stored in the second installation position storage column C22 is an address (city / ward / town / village name and street number) indicating the installation position. However, the information is not limited to this, and may be the latitude and longitude of the installation position.

[0046] The second address storage column C23 stores an address (e.g., an IP address) for accessing each loudspeaker device 13 via the network N. The information stored in the second address storage column C23 is associated with identification information of the corresponding loudspeaker device 13 and information on the installation location of the corresponding loudspeaker device 13.

[0047] In this way, by storing the above-mentioned sensor device management information I1 and loudspeaker device management information I2 in the memory unit 25 of the server 20, the server 20 can manage the sensor devices 11 and loudspeaker devices 13 installed in the predetermined area A. Specifically, the server 20 can manage the installation positions of the multiple sensor devices 11 and multiple loudspeaker devices 13 in the predetermined area A, i.e., the position at which each sensor device 11 and loudspeaker device 13 is installed.

[0048] When sensor information is acquired from the loudspeaker sensor device 10 (sensor device 11), the information processing unit 21 of the server 20 associates the acquired sensor information with the installation position of the sensor device 11 that acquired the sensor information, and the time when the sensor information was acquired. Specifically, when the information processing unit 21 acquires sensor information, it refers to the sensor device management information I1 and identifies the installation position of the sensor device 11 that is the sender of the sensor information from the address of the sender of the acquired sensor information or the identification information of the sensor information. The information processing unit 21 determines that the acquired sensor information was acquired at the installation position identified as described above.

[0049] On the other hand, when it is desired to amplify a sound in a specific position or partial area within the predetermined area A, the information processing unit 21 can identify the sound amplification device 13 installed in the specific position or partial area by referring to the sound amplification device management information I2. The information processing unit 21 can select the sound amplification device 13 identified in this way as the sound amplification device 13 to be used for sound amplification, and can command the selected sound amplification device 13 to amplify the sound. The command to amplify the sound to the sound amplification device 13 can be performed, for example, by transmitting sound source data (audio data, etc.) that is desired to be amplified by the sound amplification device 13.

[0050] (5) System operation (5-1) Overview The operation of the system 100 having the above configuration will be described below. The system 100 has a plurality of loudspeaker sensor devices 10 that are installed on utility poles P and / or overhead wires L in a predetermined area A, thereby being installed throughout the predetermined area A. The system 100 also has a server 20 that manages the installation positions of the plurality of loudspeaker sensor devices 10 (sensor devices 11, loudspeaker devices 13). By operating this system 100, various useful services can be provided to people and the like present in the predetermined area A. Examples of services that can be provided by the system 100 will be described below as operation examples of the system 100.

[0051] (5-2) Example 1 An operation example 1 of the system 100 will be described with reference to Fig. 8. Fig. 8 is a flowchart showing the operation example 1 of the system 100. In the operation example 1, the sensor 111 of each sensor device 11 is an acoustic sensor, and a distribution diagram showing the sound pressure distribution in a predetermined area A is generated based on sound pressure information (sound pressure data) acquired by the acoustic sensor of each sensor device 11.

[0052] In the operation example 1, first, the information processing unit 21 of the server 20 commands the sensor devices 11 of all loudspeaker sensor devices 10 installed in a predetermined area A to measure the sound pressure at the installation position of each sensor device 11 (step S11). The sensor devices 11 that receive this command measure the sound pressure at their installation positions and obtain the measurement results as sound pressure data. At this time, the sensor devices 11 may continuously obtain multiple sound pressure values ​​within a predetermined period of time and use the average of the obtained multiple sound pressure values ​​as the sound pressure data.

[0053] Each sensor device 11 transmits the measured sound pressure data as sensor information to the server 20. The information processing unit 21 of the server 20 receives the sound pressure data transmitted from each sensor device 11 and stores the data in the storage unit 25, thereby acquiring the sound pressure data (step S12).

[0054] When acquiring the sound pressure data, the information processing unit 21 identifies the installation location of the sensor device 11 that measured the acquired sound pressure data, and associates the acquired sound pressure data with the identified installation location (step S13). Specifically, the information processing unit 21 refers to the sensor device management information I1 and identifies the installation location associated with the address of the sender of the sound pressure data, or the identification information of the sensor device 11 that acquired the sound pressure data. The information processing unit 21 associates the sound pressure data acquired in step S12 with the installation location identified above (i.e., the acquisition location of the sound pressure data). The information processing unit 21 also identifies the time when the sound pressure data was acquired from the sensor device 11, and associates the sound pressure data with the installation location.

[0055] Thereafter, the information processing unit 21 generates a sound pressure distribution map DM in the predetermined area A by drawing a sound pressure distribution map on a map representing the predetermined area A based on the sound pressure data (sound pressure value) acquired from each sensor device 11 and the installation position (acquisition position of the sound pressure data) associated with the sound pressure data (step S14). For example, a distribution map DM can be generated in which the sound pressure distribution is color-coded for each sound pressure value on a map representing the predetermined area A as shown in Fig. 9. Fig. 9 is a diagram showing an example of the sound pressure distribution map DM.

[0056] In this way, by generating a distribution diagram showing the sound pressure distribution in the predetermined area A based on the sound pressure data acquired by the acoustic sensor of each sensor device 11, it is possible to acquire data that maps the noise level in the predetermined area A. As a result, it is possible to visually identify, for example, the location in the predetermined area A that is the source of a large noise.

[0057] (5-3) System operation example 2 An operation example 2 of the system 100 will be described with reference to Fig. 10. Fig. 10 is a flowchart showing the operation example 2 of the system 100. In the operation example 2, a predetermined sound is amplified at a designated time by a loudspeaker device 13 selected from the multiple loudspeakers 13. That is, the operation example 2 enables the system 100 to realize time reservation for loudspeaker.

[0058] In the operation example 2, first, the information processing unit 21 of the server 20 selects the target loudspeaker sensor device 10 (loudspeaker device 13) to be amplified (step S21). The selection of the loudspeaker device 13 can be performed, for example, by displaying a list of the loudspeaker device management information I2 on the server 20, and the user can select the desired loudspeaker sensor device 10 (loudspeaker device 13) according to the installation location of the information displayed in the list.

[0059] Additionally, the information processing unit 21 of the server 20 can also perform selection using a first screen GUI1 including a map showing a predetermined area A and a display (shown as a small circle in FIG. 11) of the installation location of the loudspeaker sensor device 10 (loudspeaker device 13) as shown in FIG. 11. FIG. 11 is a diagram showing an example of the first screen GUI1 for selecting a loudspeaker device. Specifically, the loudspeaker device 13 can be selected as follows.

[0060] First, the information processing unit 21 causes the server 20 to display the first screen GUI1. On the map displayed on the first screen GUI1, the user surrounds a partial area to be amplified with a predetermined figure AR1 (for example, an ellipse, etc.). The information processing unit 21 accepts the selection of the partial area by the user's operation and identifies the position (address, latitude, longitude, etc.) of the partial area surrounded by the predetermined figure AR1 on the map displayed on the first screen GUI1. The information processing unit 21 refers to the loudspeaker management information I2 and identifies the loudspeaker sensor device 10 (loudspeaker 13) that exists in the identified position (partial area).

[0061] By making it possible to select the public address system 13 from which sound is to be amplified using the first screen GUI1 as described above, the public address system 13 from which sound is to be amplified can be selected more intuitively.

[0062] The selection of the loudspeaker 13 by direct input as described above and the selection of the loudspeaker 13 using the first screen GUI1 can be performed not only on the server 20 but also using a user terminal 30 that has accessed the server 20.

[0063] After selecting the desired loudspeaker devices 13 for loudspeaker amplification, the information processing unit 21 sets the date and time when the user wants to amplify the sound from each selected loudspeaker device 13 (time reservation) (step S22). The date and time of loudspeaker amplification can be set, for example, by having the server 20 display the identification information of the loudspeaker devices 13 selected in step S21 and having the user input the date and time of loudspeaker amplification for each of the identification information of the displayed loudspeaker devices 13.

[0064] Alternatively, the information processing unit 21 can set the amplification date and time by using a second screen GUI2 that displays a graph of date and time for each selected loudspeaker device 13 (identification information of the loudspeaker device 13 (loudspeaker A, loudspeaker B, loudspeaker C, loudspeaker D)) as shown in Fig. 12. Fig. 12 is a diagram showing an example of the second screen GUI2 for setting the amplification date and time. Specifically, the amplification date and time can be set as follows.

[0065] First, the information processing unit 21 causes the server 20 to display the second screen GUI2. On the first screen GUI1, the user performs an operation to represent the range of dates and times that the user wants the loudspeaker 13 to amplify with a bar graph BA on a graph showing the amplification dates and times for each loudspeaker (identification information of the loudspeaker). The information processing unit 21 accepts the user's operation and identifies the amplification dates and times for each loudspeaker 13 based on the position and length of the bar graph BA.

[0066] By setting the amplified date and time for each loudspeaker 13 using the second screen GUI2 as described above, the amplified date and time for each loudspeaker 13 can be intuitively set.

[0067] The setting of the amplification date and time by direct input as described above and the setting of the amplification date and time using the second screen GUI 2 can be performed not only on the server 20 but also by using the user terminal 30 that has accessed the server 20 .

[0068] Also, a predetermined GUI may be used to select the audio data to be amplified by the selected loudspeaker 13. For example, the second screen GUI2 can be used to specify audio data stored in the server 20 or the like, thereby selecting the audio data to be amplified by the selected loudspeaker 13. The second screen GUI2 can also be used to select audio data stored in the user terminal 30. In this case, the selected audio data is uploaded to the server 20.

[0069] After selecting the public address system 13 to be amplified and setting the date and time of amplification for the selected public address system 13, the information processing unit 21 judges whether or not each selected public address system 13 can be amplified on the set date and time (step S23). For example, a public address system 13 for which a reservation for amplification has already been made on the set date and time of amplification and / or a public address system 13 for which maintenance is scheduled for the set date and time of amplification is judged not to be amplified on the set date and time of amplification.

[0070] If it is determined that the loudspeaker 13 is unable to amplify the sound on the set date and time due to the above reasons (a reservation has already been made, maintenance is planned), etc. ("No" in step S23), the information processing unit 21 decides not to amplify the sound on the set date and time for the loudspeaker devices 13 that it has determined are unable to amplify the sound. Specifically, the information processing unit 21 does not transmit the audio data that was scheduled to be amplified to the loudspeaker devices 13 that it has determined are not to amplify the sound. Furthermore, the information processing unit 21 may notify an error if there is a loudspeaker device 13 that is unable to amplify the sound on the set date and time. In this case, in addition to notifying an error, it may notify the identification information of the loudspeaker device 13 that is unable to amplify the sound and the reason (cause) why the sound cannot be amplified.

[0071] On the other hand, if it is determined that amplification is possible on the set amplification date and time ("Yes" in step S23), the information processing unit 21 transmits to each loudspeaker 13 determined to be capable of amplification the amplification date and time set for that loudspeaker 13 and the audio data of the audio to be amplified by that loudspeaker 13 (step S24). For example, an audio file in which the audio data is encoded in a predetermined encoding format and containerized is transmitted. This makes it possible to reserve the time for amplification for each loudspeaker 13 selected in step S21.

[0072] After the time reservation for amplification is made, the amplification control unit 133 of the loudspeaker 13 that has received the amplification date and time and the audio data determines whether the current date and time is the set amplification date and time (step S25). If the current date and time is not the set amplification date and time (step S25: No), the amplification control unit 133 waits until the amplification date and time. At this time, the amplification control unit 133 may output an audio signal converted from other audio data to the speaker 131 and perform an operation to amplify the other audio from the speaker 131.

[0073] On the other hand, if the current date and time is the set amplification date and time ("Yes" in step S25), the amplification control unit 133 plays back the audio data received in step S24, converts it into an audio signal, and outputs it to the speaker 131, thereby amplifying the audio that was scheduled to be amplified on the amplification date and time from the speaker 131 (step S26).

[0074] As described above, by amplifying a predetermined sound at a specified time through a selected loudspeaker device 13 from among the multiple loudspeakers 13, it is possible to amplify the sound at a specified time to a specific position or partial area within the predetermined area A. For example, it is possible to make announcements, advertisements, etc. about an event such as a festival to be held at a specific date and time in a specific partial area (e.g., a specific shopping street or a specific region) within the predetermined area A.

[0075] (5-4) System operation example 3 An operation example 3 of the system 100 will be described with reference to Fig. 13. Fig. 13 is a flowchart showing the operation example 3 of the system 100. In the operation example 3, in response to sensor information obtained from a specific sensor device 11 among the multiple sensor devices 11, a loudspeaker device 13 selected from the multiple loudspeaker devices 13 is caused to loudspeak a sound related to the sensor information obtained from the specific sensor device 11. That is, the operation example 3 is an operation example in which the sensor device 11 and the loudspeaker device 13 work together.

[0076] Specifically, in operation example 3, the sensor 111 of each sensor device 11 is an acoustic sensor, and when the first sound is detected by the acoustic sensor, the second sound is amplified by a loudspeaker installed at a position where a person associated with the first sound is present. Below, operation example 3 will be described in which the first sound is a sound calling for help such as a scream, the person associated with the first sound is a police officer rescuing the person who uttered the sound, and the second sound is a sound calling for rescue from a police officer (for example, a sound saying "A scream has been detected near XX. Please rush")

[0077] In the operation example 3, first, when a voice is detected by any of the multiple sensor devices 11 installed in the predetermined area A ("Yes" in step S31), the information processing unit 21 of the server 20 receives the voice data of the voice and analyzes the received voice data (step S32). As a result of analyzing the received voice data, the information processing unit 21 determines whether the detected voice is a voice calling for help (first voice) (step S33).

[0078] If the voice detected by any of the sensor devices 11 is determined to be a voice calling for help ("Yes" in step S33), the information processing unit 21 identifies the installation location of the sensor device 11 (loud-speaker sensor device 10) that detected the voice calling for help based on the address of the sender of the received voice data or the identification information of the sensor device 11 and the sensor device management information I1 (step S34). For example, as shown in Fig. 14, if the voice is emitted at position P1 in a predetermined area A, the installation location of the loud-speaker sensor device 10 (sensor device 11) surrounded by a dashed line is identified. Fig. 14 is a diagram that illustrates a schematic diagram of operation example 3.

[0079] Furthermore, when a voice calling for help is detected, the information processing unit 21 identifies the location (i.e., a police box, a police station, etc.) of a person associated with the voice calling for help (i.e., a police officer who will rescue the person who made the voice calling for help) (step S35). The information processing unit 21 identifies the location P2 of the police box that is located closest to the location P1, for example, using a location search program or the like. The identified location P2 may be the address of the location P2, or the latitude and longitude of the location P2.

[0080] After identifying position P2, the information processing unit 21 identifies the loudspeaker 13 (loudspeaker sensor device 10) installed at or near position P2 (step S36). Specifically, the information processing unit 21 refers to the loudspeaker management information I2 and identifies (the identification information of) the loudspeaker 13 associated with the installation position closest to position P2. For example, as shown in Fig. 14, when position P2 in a predetermined area A is identified, the loudspeaker sensor device 10 (loudspeaker 13) surrounded by a dashed line is identified.

[0081] After identifying the loudspeaker device 13 (loudspeaker sensor device 10) installed at or near position P2, the information processing unit 21 transmits voice data of a voice (second voice) requesting assistance from a police officer to the identified loudspeaker device 13. The loudspeaker device 13 that receives the voice data amplifies the voice requesting assistance from a police officer to position P2 and its vicinity (step S37).

[0082] As described above, when the first voice is detected by any of the acoustic sensors of the multiple sensor devices 11, the second voice is amplified by the loudspeaker device 13 installed at the position where the person associated with the first voice is present, thereby allowing the person associated with the first voice, who is located at a position away from the position where the first voice was emitted, to recognize that the first voice was emitted. For example, when a voice calling for help, such as a scream, is emitted, a police officer, who is located at a position away from the position where the voice was emitted, can be made to recognize that a voice calling for help was emitted. As a result, for example, the police officer can take action, such as providing first aid to the person who emitted the voice calling for help.

[0083] (5-5) System operation example 4 Hereinafter, an operation example 4 of the system 100 will be described with reference to FIG. 15. FIG. 15 is a flowchart showing the operation example 4 of the system 100. In the operation example 4, the above operation example 3 is executed to identify the position P1 where the first voice is detected and the position P2 where the person related to the first voice is present, and then a third voice related to the first voice is amplified by the loudspeaker 13 installed on the path from the installation position (i.e., position P2) of the loudspeaker 13 that amplified the second voice to the installation position (i.e., position P1) of the sensor device 11 having the acoustic sensor that detected the first voice. The third voice is, for example, a voice requesting a person present on the path from position P2 to position P1 to respond to the detected voice calling for help (for example, a voice requesting a call to the police box, or a voice calling attention to a person present on the path).

[0084] In the operation example 4, the above operation example 3 is executed first (step S41). The operation of the system 100 in the operation example 3 has already been described, so the description will be omitted here. By executing the operation example 3, the installation position of the sensor device 11 (loudspeaker sensor device 10) installed at or near the position P1 where the voice calling for help was emitted, and the position P2 where the police officer who will provide rescue to the person who emitted the voice calling for help are present are identified.

[0085] After executing the operation example 3, the information processing unit 21 of the server 20 uses a route search program to search for a route from the position P2 where the police officer is located to the position P1 where the voice calling for help was uttered (step S41). By executing step S41, for example, a route as shown by the thick line in Fig. 16 is searched for. Fig. 16 is a diagram showing an example of the operation example 4.

[0086] After searching for the route from position P2 to position P1, the information processing unit 21 identifies the loudspeaker 13 (loudspeaker sensor device 10) installed on or near the route (step S43). Specifically, the information processing unit 21 represents the searched route as a point cloud of coordinate points (for example, coordinate points consisting of latitude and longitude), and identifies one or more loudspeaker devices 13 installed at each point on the searched route or at an installation position near the point, with reference to the loudspeaker management information I2. For example, in FIG. 16, the loudspeaker 13 (loudspeaker sensor device 10) represented by the point highlighted in black can be identified.

[0087] After identifying the loudspeaker device 13 (loudspeaker sensor device 10) installed on or near the searched route, the information processing unit 21 transmits voice data (third voice) such as a voice requesting a call to the police box and a voice alerting people on the route to the identified loudspeaker device 13. The loudspeaker device 13 that receives the voice data outputs the voice requesting a call to the police box and a voice alerting people on the route to the searched route (step S44).

[0088] As described above, after identifying the position P1 where the first sound was detected and the position P2 where the person related to the first sound is present, the third sound related to the first sound is amplified by the loudspeaker 13 installed on the path from the installation position of the loudspeaker 13 that amplified the second sound to the installation position of the sensor device 11 having the acoustic sensor that detected the first sound, so that the people present on the path can also recognize that the first sound has been emitted. For example, when a sound calling for help such as a scream is emitted, it is possible to make the people present on the path from the police box where the police officer is present to the generation position of the first sound recognize that the sound calling for help has been emitted. As a result, for example, the people present on the path can respond to the sound calling for help by reporting it to the police box.

[0089] (5-6) System operation example 5 Operation example 5 of the system 100 will be described with reference to Fig. 17. Fig. 17 is a flowchart showing operation example 5 of the system 100. In operation example 5, operation example 3 described above is executed to identify position P1 where the first sound is detected and position P2 where a person related to the first sound is present, identify loudspeaker devices 13 installed on a path from position P2 to position P1, and when a person related to the first sound approaches any of the identified loudspeaker devices 13, cause the loudspeaker device 13 to loudspeak a sound providing route guidance to position P1.

[0090] In Operation Example 5, first, the above-mentioned Operation Example 3 is executed (Step S51). The operation of the system 100 in Operation Example 3 has already been explained, and therefore the explanation will be omitted here. After executing Operation Example 3, the information processing unit 21 of the server 20 uses a route search program to search for a route from position P2 to position P1, and identifies the loudspeaker device 13 (loudspeaker sensor device 10) installed on or near the route (Steps S52 to S53). The operations in Steps S52 to S53 are the same as the operations in Steps S42 to S43 in Operation Example 4, and therefore the explanation will be omitted here.

[0091] After identifying the loudspeaker device 13 (loudspeaker sensor device 10) installed on or near the searched route, the information processing unit 21 tracks the position of the police officer (i.e., the person related to the first voice) who is heading to rescue the person who made the voice calling for help (step S54). This tracking can be realized, for example, by having the police officer carry a wireless tag such as an RF tag and having an RFID transmitter installed on the utility pole P and / or the overhead line L detect the wireless tag.

[0092] As a result of the tracking, the information processing unit 21 determines whether the police officer is approaching any of the loudspeakers 13 installed on the route from position P2 to position P1 (step S55). Whether the police officer is approaching the loudspeaker 13 is determined by comparing the position of the police officer detected by tracking with the installation position of the loudspeaker 13 specified in step S53, and if these positions match or are close to each other, it can be determined that the police officer is approaching the loudspeaker 13.

[0093] If a police officer is approaching the loudspeaker 13 (step S55: "Yes"), the information processing unit 21 causes the loudspeaker 13 to which the police officer is approaching to amplify route guidance to position P1 (step S56). The information processing unit 21 transmits voice data of a voice giving route guidance such as "Turn right at the intersection. Continue straight for 200 meters" or "You will soon be near the scene" to the loudspeaker 13 to which the police officer is approaching, and the loudspeaker control unit 133 of the loudspeaker 13 converts this voice data into an audio signal and outputs it to the speaker 131, thereby amplifying the above-mentioned route guidance to the position of the police officer.

[0094] While tracking the position of the police officer, the information processing unit 21 judges whether the police officer has arrived at position P1 (step S57). When the position of the police officer detected by tracking coincides with or is extremely close to position P1, the information processing unit 21 can judge that the police officer has arrived at position P1.

[0095] If it is determined that the police officer has arrived at position P1 (i.e., the position where the voice calling for help was emitted) ("Yes" in step S57), tracking of the police officer is stopped, and the operation of operation example 5 is stopped. On the other hand, if it is determined that the police officer has not arrived at position P1 ("No" in step S57), the above steps S54 to S57 are repeatedly executed. That is, the information processing unit 21 tracks the police officer, and when the police officer approaches the loudspeaker 13, it causes the loudspeaker 13 that the police officer has approached to loudspeaker 13 to louden route guidance.

[0096] As described above, by identifying position P1 where the first sound was detected and position P2 where the person associated with the first sound is located, identifying the loudspeaker devices 13 installed on the route from position P2 to position P1, and having the loudspeaker device 13 amplify a sound providing directions to position P1 when the person associated with the first sound approaches any of the identified loudspeaker devices 13, the person associated with the first sound can be reliably guided to position P1. For example, when a sound calling for help, such as a scream, is heard, a police officer can be reliably guided to position P1 from which the sound was heard.

[0097] (5-7) System operation example 6 Hereinafter, a sixth operation example of the system 100 will be described with reference to Fig. 18. Fig. 18 is a flowchart showing the sixth operation example of the system 100. In the sixth operation example, the sensor 111 of the sensor device 11 is an acoustic sensor, and when the acoustic sensor detects a voice related to route guidance to a specific place in a predetermined area A, a loudspeaker installed on a route from the installation position of the sensor device 11 having the acoustic sensor that detected the voice to the specific place (target position), is made to amplify a voice providing route guidance to the specific place.

[0098] In operation example 6, first, when a voice is detected by any of the multiple sensor devices 11 installed in a predetermined area A ("Yes" in step S61), the information processing unit 21 of the server 20 receives the voice data of the voice and analyzes the received voice data (step S62). As a result of analyzing the received voice data, the information processing unit 21 determines whether the detected voice is a voice requesting route guidance (step S63). A voice requesting route guidance is, for example, a voice that includes content such as "Tell me the way to XX."

[0099] If the voice detected by any of the sensor devices 11 is determined to be a voice requesting route guidance ("Yes" in step S63), the information processing unit 21 identifies the installation location of the sensor device 11 (loudspeaker sensor device 10) that detected the voice requesting route guidance based on the address of the sender of the received voice data or the identification information of the sensor device 11 and the sensor device management information I1 (step S64). The information processing unit 21 also analyzes the received voice to identify the target location where the person who requested route guidance wants to go.

[0100] Next, the information processing unit 21 searches for a route from the identified installation position of the sensor device 11 (i.e., the current position of the person who requested the route guidance) to the identified target position (step S65). The information processing unit 21 searches for a route from the identified installation position of the sensor device 11 to the target position, for example, by using a route search program or the like.

[0101] After searching for a route from the installation position of the sensor device 11 to the target position, the information processing unit 21 identifies the loudspeaker device 13 (loudspeaker sensor device 10) installed on or near the route (step S66). After identifying the loudspeaker device 13 installed on or near the searched route, the information processing unit 21 tracks the position of the person who requested route guidance (step S67). This tracking can be realized, for example, by checking whether the person who requested route guidance is included in an image captured by a camera or the like on the route. If the person who requested route guidance is included in this image, the installation position of the camera that captured the image can be identified as the position of the person who requested route guidance.

[0102] As a result of the above tracking, the information processing unit 21 judges whether the person who requested the directions is approaching any of the loudspeaker devices 13 installed on the route to the target position (step S68). If the person who requested the directions is approaching the loudspeaker device 13 (step S68: "Yes"), the information processing unit 21 causes the loudspeaker device 13 to which the person who requested the directions is approaching to amplify directions to the target position (step S69). The information processing unit 21 transmits voice data of a voice giving directions such as "Turn left at the next intersection", "Go east for 100 m", "The building across the road is the target position" to the loudspeaker device 13 to which the person who requested the directions is approaching, and the loudspeaker control unit 133 of the loudspeaker device 13 converts the voice data into a voice signal and outputs it to the speaker 131, thereby amplifying the above-mentioned directions to the person who requested the directions.

[0103] While tracking the position of the person who has requested directions, the information processing unit 21 judges whether or not this person has arrived at the target position (step S70). If it is judged that the person who has requested directions has arrived at the target position ("Yes" in step S70), tracking of this person is stopped, and the operation of operation example 6 is stopped. On the other hand, if it is judged that the person who has requested directions has not arrived at the target position ("No" in step S70), the above steps S67 to S70 are repeatedly executed. That is, the information processing unit 21 tracks the person who has requested directions, and when this person approaches the loudspeaker 13, it causes the loudspeaker 13 that the person has approached to loudspeaker the directions.

[0104] As described above, when a voice regarding directions to a specific location in a specified area A is detected, a voice providing directions to the target location is amplified by a loudspeaker device installed on the route from the installation position of the sensor device 11 having the acoustic sensor that detected the voice to the target location, thereby enabling the person who requested directions to be reliably guided to the target location where the person wants to go.

[0105] As described above, in the system 100, a plurality of loudspeaker sensor devices 10 (sensor device 11, loudspeaker device 13) that acquire sensor information in a predetermined area A and loudspeak the information in the predetermined area A are provided on at least some of the plurality of utility poles P provided in the predetermined area A and / or at least some of the overhead lines L provided on the plurality of utility poles P. In general, utility poles P and overhead lines L are provided throughout the predetermined area A where people gather, such as in urban areas and shopping districts. Utility poles P and overhead lines L are provided particularly on or near the paths of people, such as roads. For this reason, by providing the loudspeaker sensor devices 10 on the utility poles P and / or overhead lines L, the loudspeaker sensor devices 10 can be easily provided throughout the predetermined area. In particular, the loudspeaker sensor devices 10 can be easily provided throughout the predetermined area, such as in locations that may be paths of people, such as roads, that exist in the predetermined area A, or in the vicinity thereof.

[0106] In the system 100, the server 20 manages the installation positions of the multiple loudspeaker sensor devices 10 (sensor device 11, loudspeaker device 13). The server 20 acquires sensor information from any of the multiple sensor devices 11, and associates the acquired sensor information with the installation position of the sensor device 11 that acquired it. The server 20 also selects a loudspeaker device 13 installed in a specific position or partial area in the predetermined area A, and commands the selected loudspeaker device 13 to amplify the sound. This allows the server 20 to provide various useful services related to the predetermined area A, such as a service using the sensor information acquired in the predetermined area A, and a service that amplifies various sounds to people or the like present in the predetermined area A. For example, the server 20 can provide services such as those in the operation examples 1 to 6 described above.

[0107] 2. Second embodiment (1) Overview The sensor information collected by the sensor device 11 of the system 100 can be used for various purposes other than amplification from the loudspeaker 13. For example, as shown in FIG. 19, the system 100 can output the sensor information to another system (called a linked system 200) connected via a network N and operate in cooperation with the linked system 200. The linked system 200 is, for example, a system operated by a service provider that provides various services different from the system 100 by collecting sensor information by the sensor device 11 and amplifying the information by the loudspeaker 13. FIG. 19 is a diagram showing the configuration of a system in the second embodiment.

[0108] In the second embodiment, the system 100 transmits (provides) the sensor information collected and organized based on the above-mentioned operation example, etc., to the linkage system 200 on a regular or irregular basis. The linkage system 200 executes various services using the sensor information received (provided) from the system 100. In this manner, the system 100 can provide the collected and organized sensor information to the outside for the purpose of linking with an external service. An example of linkage between the system 100 and the linkage system 200 in the second embodiment will be described below.

[0109] (2) Collaboration example 1 The system 100 can cooperate with a cooperation system 200 that provides various services using drones, for example. The cooperation system 200 includes one or more drone ports that serve as takeoff and landing points for drones (unmanned aerial vehicles), and flies drones waiting at the drone ports toward specific locations. The drones have, for example, a cargo transport mechanism.

[0110] In cooperation example 1, after identifying the installation location of the sensor device 11 that detected the first sound based on operation example 3 described in the first embodiment, the information processing unit 21 of the server 20 of the system 100 transmits information on the identified installation location to the cooperation system 200. The cooperation system 200 sets the installation location of the sensor device 11 received from the system 100 as the landing target location of the drone, and flies the drone from the drone port. The drone for which the landing target location has been set uses a cargo transport mechanism to fly and transport materials that are deemed to be highly necessary according to the event that can be grasped from the first sound to the landing target location.

[0111] In the first cooperation example, an event that can be understood from the first voice is, for example, the occurrence of a sudden illness. In addition, an AED (Automated External Defibrillator) is, for example, an item to be transported by the drone.

[0112] By this cooperation, when a person who needs treatment with an AED (for example, a person who is suddenly ill) is found within the specified area A, assistance can be provided promptly regarding the treatment of the person.

[0113] (3) Collaboration example 2 The system 100 is installed, for example, in a building or the like within a predetermined area A, and can cooperate with a linking system 200 that performs in-house broadcasting within the building. The linking system 200 includes a sound source (audio data) for in-house broadcasting, an audio amplifier, and one or more speakers. The linking system 200 has a function of amplifying the sound source with the audio amplifier and broadcasting it through the speaker.

[0114] In collaboration example 2, when a predetermined event is detected by the sensor device 11 of the system 100, the information processing unit 21 of the server 20 of the system 100 identifies the installation location of the sensor device 11 that detected the event, and transmits information about this installation location to the collaboration system 200. The collaboration system 200, which is installed in a building near the installation location of the sensor device 11 (for example, within a predetermined distance range from the installation location of the sensor device 11), broadcasts loudspeakers within the premises of the building to inform the occurrence of the event detected by the sensor device 11. In collaboration example 2, the event is, for example, the occurrence of a fire, an accident, an incident, etc.

[0115] By this type of coordination, when an event occurs within a specified area A that people should be aware of, the information can be communicated not only to people outdoors using the loudspeaker 13, but also to people in nearby buildings using the coordination system 200.

[0116] (4) Collaboration example 3 The system 100 can be linked to a linked system 200 that provides a real estate service that assesses land value based on the area environment such as noise. The linked system 200 is, for example, a system in which a real estate agent manages properties.

[0117] In Linkage Example 3, the information processing unit 21 of the server 20 of the system 100 transmits information about sound pressure distribution in a predetermined area A, generated based on Operation Example 1 described in the first embodiment, to the linkage system 200. The linkage system 200 grasps the noise level in the predetermined area A from the received sound pressure distribution (noise level) information, and can use the information to visualize the noise situation in the area where managed properties are located in the predetermined area A and for land appraisal.

[0118] (5) Collaboration example 4 The system 100 can cooperate with a cooperation system 200 of an institution such as a government agency that performs urban planning, for example. In cooperation example 4, the information processing unit 21 of the server 20 of the system 100 transmits information on sound pressure distribution in a predetermined area A generated based on the operation example 1 described in the first embodiment to the cooperation system 200. The information is provided to the cooperation system 200. The cooperation system 200 can grasp the urban environment in the predetermined area A from the received information on sound pressure distribution and use it for decision-making on urban planning and environmental policies.

[0119] (6) Collaboration example 5 The system 100 can be linked with an association system 200 that dispatches taxis and provides advertisements, for example. In association example 5, the information processing unit 21 of the server 20 of the system 100 transmits information on sound pressure distribution in a predetermined area A, generated based on the operation example 1 described in the first embodiment, to the association system 200. The association system 200 can grasp the number of people and the state of activity in the predetermined area A from the information on sound pressure distribution, and can use the information to formulate a taxi dispatch plan and a plan to provide advertisements.

[0121] 3. Other embodiments Although one embodiment of the present disclosure has been described above, the present disclosure is not limited to the above embodiment and various modifications are possible. In particular, the multiple embodiments and modifications described in this specification can be arbitrarily combined as necessary. (A) The sensor device 11 and the loudspeaker device 13 do not have to be integrated into the loudspeaker sensor device 10. In other words, the sensor device 11 and the loudspeaker device 13 may be separate devices. When the sensor device 11 and the loudspeaker device 13 are separate devices, each of the sensor device 11 and the loudspeaker device 13 may have a power supply unit that supplies driving power.

[0122] (B) When the sensor device 11 and the loudspeaker 13 are separate devices, the installation positions of the sensor device 11 and the loudspeaker 13 can be set arbitrarily. For example, as shown in Fig. 20, both the sensor device 11 and the loudspeaker 13 may be installed on a utility pole P, and the sensor device 11 and the loudspeaker 13 may be alternately provided on an overhead line L. The positional relationship between the sensor device 11 and the loudspeaker 13 on the utility pole P may be, for example, as shown in Fig. 20, such that the loudspeaker 13 is on the upper side of the utility pole P and the sensor device 11 is on the lower side of the utility pole P. This positional relationship may be reversed. Fig. 20 is a diagram showing another installation example of the sensor device 11 and the loudspeaker 13.

[0123] Furthermore, for example, the loudspeaker device 13 may be provided on the utility pole P and the sensor device 11 may be provided on the overhead line L, and so on, so that the loudspeaker devices 13 and the sensor devices 11 may be provided alternately in a predetermined area A.

[0124] (C) The system 100 may be capable of executing all of the above-described operational examples 1 to 6, or may be capable of executing only some of them.

[0125] (D) In ​​the above-mentioned operation example 2, the amplification date and time and the audio data are transmitted to the loudspeaker 13, and the loudspeaker control unit 133 of the loudspeaker 13 determines the arrival of the amplification date and time and amplifies the audio data. This is not limiting, and the information processing unit 21 of the server 20 may determine the arrival of the amplification date and time and transmit the audio data to be amplified to the target loudspeaker 13 when the amplification date and time arrives. In this case, the loudspeaker control unit 133 of the loudspeaker 13 may play the received audio data immediately upon receiving the audio data from the server 20. Alternatively, the information processing unit 21 may stream the audio data to the loudspeaker 13 using a predetermined protocol such as RTSP (Real Time Streaming Protocol).

[0126] (E) Watermark information using audio watermarking may be embedded in the audio amplified from the loudspeaker device 13. The watermark information is, for example, information that can be decoded by a vehicle or a service robot traveling near the utility pole P and / or the overhead line L, and is a signal that generates some kind of instruction for the vehicle or the service robot.
