In order to provide useful services regarding a wide area, it is preferable to install sensor devices and voice amplification devices without limitation in the area. For example, it is preferable to install sensor devices and voice amplification facilities without limitation along the movement routes of people or in the vicinity thereof existing in urban areas and shopping streets. On the other hand, in order to install these devices without limitation in a wide area, it is necessary to secure installation spaces at many locations in the wide area, but it is difficult to secure a large number of installation spaces within the wide area.

[0005] An object of the present disclosure is to realize a system that can provide useful services related to a predetermined area by installing sensor devices and loudspeaker equipment without limitation in a predetermined area where people gather, such as in urban areas and shopping streets.

Generally, utility poles and overhead lines are installed without limitation in a predetermined area where people gather, such as in urban areas and shopping streets. The utility poles and overhead lines are particularly provided along the traffic flow of people, such as roads, or in the vicinity thereof. Therefore, by installing sensor devices and loudspeaker devices on the utility poles and / or overhead lines, the sensor devices and loudspeaker devices can be easily installed without limitation in the predetermined area.

MODE FOR CARRYING OUT THE INVENTION

[0012] 1. First Embodiment (1) Outline of the System Hereinafter, the system 100 will be described. The system 100 is a system for acquiring various sensor information and / or amplifying a predetermined voice toward a predetermined area A, which is an area (referred to as a predetermined area A) used by many people such as a predetermined area, an urban area existing in the predetermined area, and a shopping street. The system 100 can provide various services based on the acquired sensor information and a voice amplification service for the entire predetermined area A or a specific location or area of the predetermined area A. Specific examples of these services will be described in detail later.

[0013] (2) Configuration of the System Using FIG. 1, the configuration of system 100 will be described. FIG. 1 is a diagram showing the configuration of system 100. System 100 includes a plurality of voice amplification sensor devices 10 and a server 20.

[0014] The plurality of voice amplification sensor devices 10 are provided in a predetermined area A where it is desired to perform voice amplification and / or acquire various sensor information. They amplify a predetermined voice toward the predetermined area A and / or acquire various sensor information regarding the predetermined area A. As will be described later, the voice amplification sensor device 10 is a system that integrates a sensor device 11 for acquiring sensor information and a voice amplification device 13 for performing voice amplification.

[0015] The plurality of voice amplification sensor devices 10 are installed using public infrastructure existing in the predetermined area A. Specifically, the plurality of voice amplification sensor devices 10 are installed on at least a part of a plurality of utility poles P provided in the predetermined area A and / or at least a part of a wire line L installed by being strung between the plurality of utility poles P. The wire line L is, for example, a power line for supplying power or a communication line for performing wired communication.

[0016] [[ID=1~6]]

[0017] More specifically, as shown in FIG. 2, one voice amplification sensor device 10 is provided on each of all or part of the plurality of utility poles P, and one voice amplification sensor device 10 is provided on each of all or part of the wire line L strung between two utility poles P. FIG. 2 is an example of the installation of the voice amplification sensor device 10 on the utility pole P and the wire line L.

[0017] The public infrastructure having the plurality of utility poles P and the wire line L strung between the plurality of utility poles P is provided without limitation in the predetermined area A in order to provide power and communication without limitation to buildings, factories, houses, etc. existing in the predetermined area A. The utility pole P is provided, for example, along a road provided in the predetermined area A, and the wire line L is strung along the installation direction of the plurality of utility poles P (i.e., the road) and from the utility pole P to buildings, factories, houses, etc.

[0018] Therefore, by installing the voice amplification sensor device 10 on the utility pole P and / or the overhead line L installed in the predetermined area A, a plurality of voice amplification sensor devices 10 can be installed without limitation in the predetermined area A. For example, as shown in FIG. 3, the voice amplification sensor device 10 can be installed along almost all the roads existing in the predetermined area A. FIG. 3 is a diagram showing an example of the installation state of the voice amplification sensor device 10 in the predetermined area A.

[0019] In this way, by installing the voice amplification sensor device 10 using the public infrastructure (that is, the utility pole P and / or the overhead line L) provided in the predetermined area A, it is not necessary to secure a large number of installation spaces for installing the voice amplification sensor device 10 in the area A, and without newly installing poles and the like that serve as fixtures for fixing the voice amplification sensor device 10 separately, the voice amplification sensor device 10 can be easily installed without limitation in the predetermined area A.

[0020] Also, the roads provided in the predetermined area A serve as the movement routes of people and the like existing in the predetermined area A. Therefore, by installing the voice amplification sensor device 10 along the roads provided in the predetermined area A, the system 100 can acquire sensor information regarding many people existing in the predetermined area A, and can also perform voice amplification for many people.

[0021] In addition, generally, power is supplied to the overhead line L installed using the utility pole P. Therefore, by installing the voice amplification sensor device 10 on the utility pole P and / or the overhead line L, power for driving the voice amplification sensor device 10 can be obtained from the overhead line L. That is, the power of the voice amplification sensor device 10 can be easily secured without, for example, installing separate power supply facilities.

[0022] The voice amplification sensor device 10 is connected to the network N. The voice amplification sensor device 10 can communicate with the server 20 via the network N. The network N is, for example, the Internet, a wide area LAN, or the like.

[0023] The server 20 is a computer system composed of a CPU, a storage device (such as RAM, ROM, SSD, hard disk, etc.), various interfaces (such as a communication interface), and the like. The server 20 is connected to the network N and can communicate with each of the plurality of voice amplification sensor devices 10.

[0024] The server 20 manages a plurality of voice amplification sensor devices 10 installed in a predetermined area A. As will be described later, the server 20 manages the installation positions of the plurality of voice amplification sensor devices 10. When the server 20 acquires sensor information from any one of the plurality of voice amplification sensor devices 10, the server 20 associates the sensor information with the installation position of the voice amplification sensor device 10 (sensor device 11) from which the sensor information is acquired and the time (date and time, time, etc.) at which the sensor information is acquired by the voice amplification sensor device 10. Thereby, it is possible to specify where and when the sensor information was acquired.

[0025] In addition, when the server 20 wants to perform voice amplification for a specific position or partial area within the predetermined area A, the server 20 selects the voice amplification sensor device 10 (voice amplification device 13) installed in the specific position or partial area and issues a command to perform voice amplification to the selected voice amplification device. Thereby, voice amplification can be performed for any position or any area within the predetermined area A.

[0026] The system 100 may include a user terminal 30. The user terminal 30 is connected to the network N and can communicate with the server 20. The user terminal 30 may be able to communicate with the voice amplification sensor device 10. The user terminal 30 is 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 Voice Amplification Sensor Device Next, the configuration of the voice amplification sensor device 10 will be described with reference to FIG. 4. FIG. 4 is a diagram showing the configuration of the voice amplification sensor device 10. The voice amplification sensor device 10 includes a sensor device 11, a voice amplification device 13, and a power supply unit 15. That is, the voice amplification sensor device 10 is a device that integrates the sensor device 11 and the voice amplification device 13.

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

[0029] The data generation unit 113 is hardware (an electric circuit) that generates sensor information from various measurement results obtained by the sensor 111. When the sensor 111 is a CCD sensor, the data generation unit 113 generates image data as sensor information from the information acquired by the CCD sensor. When the sensor 111 is an acoustic sensor, the data generation unit 113 generates the sound pressure value measured by the acoustic sensor as sensor information. Also, the data generation unit 113 generates sensor information that is voice data from the voice measured by the acoustic sensor. When the sensor 111 is a weather sensor, the data generation unit 113 generates sensor information in which values such as temperature, humidity, and wind speed detected by the weather sensor are digitized. Note that the above functions of the data generation unit 113 may be realized by a program executable by the sensor device 11.

[0030] The first communication unit 115 is hardware (a 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 device 13 amplifies sound around the installation position of the sound amplification sensor device 10. The loudspeaker device 13 includes a speaker 131, a sound amplification 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 sound amplification sensor device 10. The speaker 131 may be an omnidirectional speaker or a directional speaker with directivity towards a sidewalk or a roadway.

[0032] The sound amplification control unit 133 is a circuit (electrical circuit) that converts the audio data received from the server 20 via the second communication unit 135 into an audio signal and outputs it to the speaker 131. Note that the above function of the sound amplification 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 the audio data to be amplified from the server 20.

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

[0035] On the other hand, the power supply unit 15 of the sound amplification sensor device 10 installed on a utility pole P or a low-voltage power line L (for example, a communication line) can be composed of, for example, an electrical circuit that converts the power whose voltage has been lowered from a voltage converter (transformer) provided on the utility pole P, or the power of the low-voltage power line L, into power that can be used by the sensor device 11 and the loudspeaker device 13.

[0036] Note that the voice amplification sensor device 10 may be provided with both a high-voltage power supply unit 15 composed of the coil and an electric circuit and a low-voltage power supply unit 15 composed of the electric circuit.

[0037] (4) Configuration of the server Hereinafter, the configuration of the server 20 will be described with reference to FIG. 5. FIG. 5 is a diagram showing the configuration of the server 20. The server 20 includes an information processing unit 21, a third communication unit 23, and a storage unit 25. The information processing unit 21 is composed of a CPU of the server 20 or the like and executes various information processes related to the server 20.

[0038] Specifically, the information processing unit 21 acquires sensor information from any one of a plurality of voice amplification sensor devices 10 (sensor devices 11), and associates the acquired sensor information with the installation position of the voice amplification sensor device 10 from which the sensor information was acquired and the time when the voice amplification sensor device 10 acquired the sensor information. That is, when the information processing unit 21 acquires sensor information, it determines where and when in the predetermined area A the sensor information was acquired. In addition, the information processing unit 21 performs various information processes using the acquired sensor information and provides services related to the sensor information.

[0039] In addition, when performing voice amplification, the information processing unit 21 determines which position or sub-area in the predetermined area A to perform voice amplification on, and identifies the voice amplification sensor device 10 (voice amplification device 13) to be the target of voice amplification. The information processing unit 21 transmits the voice data to be amplified to the identified voice amplification sensor device 10 (voice amplification device 13). Note that 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 voice amplification 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 voice amplification sensor device 10 (sensor device 11) and transmits voice data to be amplified to the voice amplification sensor device 10 (voice amplification device 13).

[0041] The storage unit 25 is composed of a storage device of the server 20 and stores various information used in the server 20, sensor information acquired from the voice amplification sensor device 10, and the like. Specifically, the storage unit 25 stores sensor device management information I1 and voice amplification 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 plurality of sensor devices 11. The first installation position storage column C12 stores information regarding the installation position of each of the plurality of 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, town, village name and house number) representing the installation position. However, it 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 (for example, an 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 the information regarding the installation position of the corresponding sensor device 11.

[0044] The public address device management information I2 is information for managing the public address device 13 installed in a predetermined area A. As shown in FIG. 7, the public address device 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 public address device management information I2.

[0045] The second identification information storage column C21 stores the identification information of each of the plurality of public address devices 13. The second installation position storage column C22 stores information regarding the installation position of each of the plurality of public address devices 13. The information stored in the second installation position storage column C22 is associated with the identification information of the corresponding public address device 13. In the example shown in FIG. 7, the information stored in the second installation position storage column C22 is the address (city, town, village name and house number) representing the installation position. However, it is not limited to this, and the information stored in the second installation position storage column C22 may be the latitude and longitude of the installation position.

[0046] The second address storage column C23 stores an address (for example, an IP address, etc.) for accessing each public address device 13 via the network N. The information stored in the second address storage column C23 is associated with the identification information of the corresponding public address device 13 and the information regarding the installation position of the corresponding public address device 13.

[0047] In this way, by storing the above sensor device management information I1 and public address device management information I2 in the storage unit 25 of the server 20, the server 20 can manage the sensor device 11 and the public address device 13 installed in the predetermined area A. Specifically, the server 20 can manage the installation positions of the plurality of sensor devices 11 and the plurality of public address devices 13 in the predetermined area A, that is, at which positions each sensor device 11 and public address device 13 is installed.

[0048] When sensor information is acquired from the voice amplification 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 from which the sensor information is acquired and the time when the sensor information is 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 source of the acquired sensor information from the address of the source 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 perform voice amplification for a specific position or a partial area within a predetermined area A, the information processing unit 21 can identify the voice amplification device 13 installed within the specific position or partial area by referring to the voice amplification device management information I2. The information processing unit 21 selects the thus identified voice amplification device 13 as the voice amplification device 13 to be amplified and can issue a command to perform voice amplification to the selected voice amplification device 13. The voice amplification command to the voice amplification device 13 can be issued, for example, by transmitting the sound source data (such as voice data) to be amplified to the voice 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 voice amplification sensor devices 10 installed without limitation in a predetermined area A by being installed on the utility pole P and / or the overhead line L in the predetermined area A. Further, the system 100 has a server 20 that manages the installation positions of the plurality of voice amplification sensor devices 10 (sensor devices 11, voice amplification devices 13). By operating this system 100, various useful services can be provided to people and the like existing 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) Operation example 1 Using FIG. 8, an operating example 1 of the system 100 will be described. FIG. 8 is a flowchart showing the operating example 1 of the system 100. In operating example 1, the sensor 111 of each sensor device 11 is an acoustic sensor, and based on the sound pressure information (sound pressure data) acquired by the acoustic sensor of each sensor device 11, a distribution diagram representing the sound pressure distribution in a predetermined area A is generated.

[0052] In operating example 1, first, the information processing unit 21 of the server 20 issues a command to each sensor device 11 of all the loudspeaker sensor devices 10 installed in the predetermined area A to measure the sound pressure at the installation position of each sensor device 11 (step S11). The sensor device 11 that receives this command measures the sound pressure at its installation position and acquires the measurement result as sound pressure data. At this time, the sensor device 11 may continuously acquire a plurality of sound pressure values within a predetermined period and use the average of the acquired plurality of 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 it in the storage unit 25, thereby acquiring the sound pressure data (step S12).

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

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

[0056] In this way, by generating a distribution diagram representing the sound pressure distribution in the predetermined area A based on the sound pressure data acquired by the acoustic sensors of each sensor device 11, data mapping the noise level in the predetermined area A can be obtained. As a result, for example, it is possible to visually identify where in the predetermined area A is a major noise source.

[0057] (5-3) Operation Example 2 of the System The 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 operation example 2, a selected one of the plurality of loudspeaker devices 13 is caused to amplify a predetermined voice at a specified time. That is, by operation example 2, the system 100 can realize voice amplification time reservation.

[0058] In operation example 2, first, the information processing unit 21 of the server 20 selects a loudspeaker sensor device 10 (loudspeaker device 13) to be amplified (step S21). The selection of the loudspeaker device 13 can be made, for example, by causing the server 20 to list-display the loudspeaker device management information I2, and allowing the user to select a desired loudspeaker sensor device 10 (loudspeaker device 13) according to the installation position of the list-displayed information.

[0059] In addition, the information processing unit 21 of the server 20 can also make a selection using the first screen GUI1 including a map representing a predetermined area A as shown in FIG. 11 and the display of the installation position of the voice amplification sensor device 10 (voice amplification device 13) (displayed as small circles in FIG. 11). FIG. 11 is a diagram showing an example of the first screen GUI1 for selecting a voice amplification device. Specifically, the voice amplification device 13 can be selected as follows.

[0060] First, the information processing unit 21 causes the server 20 to display the first screen GUI1. The user surrounds the partial area to be amplified with a predetermined figure AR1 (for example, an ellipse, etc.) on the map displayed on the first screen GUI1. The information processing unit 21 accepts the selection of the partial area by the above operation of the user and specifies the position (address, latitude and 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 voice amplification device management information I2 and specifies the voice amplification sensor device 10 (voice amplification device 13) existing at the specified position (partial area).

[0061] By making it possible to select the voice amplification device 13 for which voice amplification is to be performed using the first screen GUI1 as described above, the voice amplification device 13 for which voice amplification is to be performed can be selected more intuitively.

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

[0063] After selecting the voice amplification device 13 for which voice amplification is to be performed, the information processing unit 21 sets the date and time for which voice amplification is to be performed for each selected voice amplification device 13 (time reservation) (step S22). The setting of the voice amplification date and time can be performed, for example, by causing the server 20 to display the identification information of the voice amplification device 13 selected in step S21 and the user inputting the voice amplification date and time for each displayed identification information of the voice amplification device 13.

[0064] In addition, the information processing unit 21 can also set the voice amplification date and time by using the second screen GUI2 that graphically displays the date and time for each selected voice amplification device 13 (identification information of the voice amplification device 13 (Voice Amplification A, Voice Amplification B, Voice Amplification C, Voice Amplification D)) as shown in FIG. 12. FIG. 12 is a diagram showing an example of the second screen GUI2 for setting the voice amplification date and time. Specifically, the voice 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. The user performs an operation on the first screen GUI1 to represent the range of the date and time when voice amplification is desired for the voice amplification device 13 with a bar graph BA on the graph representing the voice amplification date and time for each voice amplification device (identification information). The information processing unit 21 accepts the above operation of the user and specifies the voice amplification date and time of each voice amplification device 13 based on the position and length of the bar graph BA.

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

[0067] Note that the setting of the voice amplification date and time by direct input described above and the setting of the voice amplification date and time using the second screen GUI2 can be performed not only on the server 20 but also using the user terminal 30 that has accessed the server 20.

[0068] Also, it may be possible to select the voice data to be amplified by the selected voice amplification device 13 using a predetermined GUI. For example, by specifying the voice data stored in the server 20 or the like using the second screen GUI2, the voice data to be amplified by the selected voice amplification device 13 can be selected. Also, the voice data stored in the user terminal 30 can be selected using the second screen GUI2. In this case, the selected voice data is uploaded to the server 20.

[0069] After selecting the loudspeaker device 13 to be amplified and setting the amplification date and time for the selected loudspeaker device 13, the information processing unit 21 determines whether each selected loudspeaker device 13 can be amplified at the set amplification date and time (step S23). For example, a loudspeaker device 13 for which an amplification reservation has already been made at the set amplification date and time and / or a loudspeaker device 13 for which maintenance is planned at the set amplification date and time is determined not to be able to be amplified at the set amplification date and time.

[0070] If it is determined that amplification is not possible at the set amplification date and time due to the above reasons (already reserved, maintenance is planned, etc.) (No in step S23), the information processing unit 21 decides not to amplify the loudspeaker device 13 for which it has been determined that amplification is not possible at the set amplification date and time. Specifically, the voice data that was originally scheduled to be amplified is not transmitted to the loudspeaker device 13 for which it has been decided not to amplify. Also, if there is a loudspeaker device 13 that cannot be amplified at the set amplification date and time, the information processing unit 21 may notify an error. In this case, in addition to notifying the error, the identification information of the loudspeaker device 13 that cannot be amplified and the reason (cause) why it cannot be amplified may also be notified.

[0071] On the other hand, if it is determined that amplification is possible at the set amplification date and time (Yes in step S23), the information processing unit 21 transmits the set amplification date and time for the respective loudspeaker devices 13 for which amplification is possible and the voice data of the voice to be amplified by the loudspeaker device 13 (step S24). For example, a voice file in which the voice data is encoded in a predetermined encoding format and containerized is transmitted. Thereby, it is possible to make a time reservation for amplification for each loudspeaker device 13 selected in step S21.

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

[0073] On the other hand, if the current date and time is the set loudspeaker date and time (Yes in step S25), the loudspeaker control unit 133 plays 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 at the loudspeaker date and time from the speaker 131 (step S26).

[0074] As described above, by amplifying a predetermined audio at a specified time for the selected loudspeaker device 13 among the plurality of loudspeaker devices 13, it is possible to amplify the audio at a specified time for a specific position or sub-region within a predetermined region A. For example, in a specific sub-region (e.g., a specific shopping street, a specific area) within a predetermined region A, it is possible to announce and promote events such as festivals held at specific dates and times.

[0075] (5-4) Operation Example 3 of the System Using FIG. 13, operation example 3 of the system 100 will be described. FIG. 13 is a flowchart showing operation example 3 of the system 100. In operation example 3, according to the sensor information obtained from a specific sensor device 11 among the plurality of sensor devices 11, the selected loudspeaker device 13 among the plurality of loudspeaker devices 13 amplifies the audio related to the sensor information obtained from the specific sensor device 11. That is, operation example 3 is an operation example in which the sensor device 11 and the loudspeaker device 13 cooperate.

[0076] Specifically, in Operation Example 3, the sensor 111 of each sensor device 11 is an acoustic sensor. When a first voice is detected by the acoustic sensor, a second voice is amplified to a loudspeaker installed at the position where the person related to the first voice exists. In the following, a voice seeking help such as a scream is defined as the first voice, a police officer who rescues the person who uttered the voice is defined as the person related to the first voice, and Operation Example 3 where the second voice is a voice seeking rescue from the police officer (for example, a voice saying "A scream has been detected near XX. Please rush over") will be described.

[0077] In Operation Example 3, first, when a voice is detected by any one of the plurality of sensor devices 11 installed in a 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). The information processing unit 21 determines whether the detected voice is a voice seeking help (first voice) based on the result of the analysis of the received voice data (step S33).

[0078] When it is determined that the voice detected by any one of the sensor devices 11 is a voice seeking help ( "Yes" in step S33), the information processing unit 21 identifies the installation position of the sensor device 11 (amplifying sensor device 10) that detected the voice seeking help based on the address of the transmission source 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, when the above voice is uttered at the position P1 in the predetermined area A, the installation position of the amplifying sensor device 10 (sensor device 11) surrounded by the broken line is identified. FIG. 14 is a diagram schematically showing Operation Example 3.

[0079] Also, when the voice seeking help is detected, the information processing unit 21 identifies the location of the person related to the voice seeking help (i.e., the police officer who rescues the person who uttered the voice seeking help) (step S35). For example, the information processing unit 21 uses a location search program or the like to identify the location P2 of the police box closest to the location P1. The identified location P2 may be the address of the location P2 or the latitude and longitude of the location P2.

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

[0081] After identifying the loudspeaker device 13 (loudspeaker sensor device 10) installed at or near the location P2, the information processing unit 21 transmits the voice data of the voice (second voice) asking the police officer for rescue to the identified loudspeaker device 13. The loudspeaker device 13 that has received the voice data broadcasts the voice asking the police officer for rescue at and near the location P2 (step S37).

[0082] As described above, when the first voice is detected by any of the acoustic sensors of the plurality of sensor devices 11, by causing the loudspeaker device 13 installed at the location where the person related to the first voice exists to broadcast the second voice, it is possible to make the person related to the first voice who exists at a location away from the location where the first voice was uttered recognize that the first voice was uttered. For example, when a voice seeking help such as a scream is uttered, it is possible to make the police officer who exists at a location away from the location where the voice was uttered recognize that the voice seeking help was uttered. As a result, for example, the police officer can take measures such as rescuing the person who uttered the voice seeking help.

[0083] (5-5) System Operation Example 4 Hereinafter, with reference to FIG. 15, operation example 4 of system 100 will be described. FIG. 15 is a flowchart showing operation example 4 of system 100. In operation example 4, after executing the above operation example 3 to identify the position P1 where the first voice is detected and the position P2 where the person related to the first voice exists, further, from the installation position of the voice amplifier 13 (i.e., position P2) that amplified the second voice, to the installation position of the sensor device 11 having the acoustic sensor that detected the first voice (i.e., position P1), the voice amplifier 13 installed on the path is made to amplify the third voice related to the first voice. The third voice is, for example, a voice for seeking a response to the voice seeking help detected for a person existing on the path from position P2 to position P1 (for example, a voice requesting a report to the alternate, a voice alerting a person existing on the path).

[0084] In operation example 4, first, the above operation example 3 is executed (step S41). Since the operation of system 100 in operation example 3 has already been described, the description thereof will be omitted here. By executing operation example 3, the installation position of the sensor device 11 (voice amplifier sensor device 10) installed at or near the position P1 where the voice seeking help was emitted, and the position P2 where a police officer who performs first aid on the person who emitted the voice seeking help exists are identified.

[0085] After executing operation example 3, the information processing unit 21 of the server 20 searches for a path from the position P2 where the police officer exists to the position P1 where the voice seeking help was emitted using a route search program (step S41). By executing step S41, for example, a path as shown by the thick line in FIG. 16 is searched. FIG. 16 is a diagram schematically showing operation example 4.

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

[0087] After identifying the voice amplifier 13 (voice amplification sensor device 10) installed on or near the searched route, the information processing unit 21 transmits voice data such as a voice requesting an alternating report and a voice alerting a person existing on the route (third voice) to the identified voice amplifier 13. The voice amplifier 13 that has received the voice data amplifies the voice requesting an alternating report, the voice alerting a person existing on the route, etc. in the direction of the searched route (step S44).

[0088] As described above, after identifying the position P1 where the first voice was detected and the position P2 where the person related to the first voice exists, further, for the voice amplifier 13 installed on the route from the installation position of the voice amplifier 13 that amplified the second voice to the installation position of the sensor device 11 having the acoustic sensor that detected the first voice, by amplifying the third voice regarding the first voice, it is possible to make the person existing on the route recognize that the first voice was emitted. For example, when a voice seeking help such as a scream is emitted, it is possible to make the person existing on the route from the police box where the police officer exists to the generation position of the first voice recognize that a voice seeking help was emitted. As a result, for example, the person existing on the route can take actions such as reporting to the police box in response to the voice seeking help.

[0089] (5-6) Operation example 5 of the system Using FIG. 17, an operation example 5 of the system 100 will be described. FIG. 17 is a flowchart showing the operation example 5 of the system 100. In operation example 5, 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 exists, identify the voice amplification device 13 installed on the path from the position P2 to the position P1, and when approaching any of the voice amplification devices 13 where the person related to the first voice is identified, amplify the voice for guiding the way to the position P1 by the voice amplification device 13.

[0090] In operation example 5, first, the above operation example 3 is executed (step S51). Since the operation of the system 100 in operation example 3 has already been described, the description thereof will be omitted here. After executing operation example 3, the information processing unit 21 of the server 20 searches for the path from the position P2 to the position P1 using the path search program, and identifies the voice amplification device 13 (voice amplification sensor device 10) installed on or near the path (steps S52 - S53). The operations in steps S52 - S53 are the same as the operations in steps S42 - S43 in operation example 4, so the description will be omitted here.

[0091] After identifying the voice amplification device 13 (voice amplification sensor device 10) installed on or near the searched path, the information processing unit 21 tracks the position of the police officer (that is, the person related to the first voice) who is going to the rescue of the person who uttered the voice 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 detecting the wireless tag with the RFID transmitter provided on the utility pole P and / or the overhead line L.

[0092] Based on the result of the above tracking, the information processing unit 21 determines whether the police officer is approaching any of the voice amplification devices 13 installed on the path from the position P2 to the position P1 (step S55). Whether the police officer is approaching the voice amplification device 13 can be determined by comparing the position of the police officer detected by the tracking with the installation position of the voice amplification device 13 identified in step S53, and determining that the police officer is approaching the voice amplification device 13 when these positions match or are close.

[0093] When the police officer approaches the loudspeaker device 13 (Yes in step S55), the information processing unit 21 causes the loudspeaker device 13 that the police officer is approaching to announce the route to position P1 (step S56). For example, the information processing unit 21 transmits voice data of voice for route guidance such as "Turn right at the intersection. Go straight for 200 meters as it is" and "You will be near the scene soon" to the loudspeaker device 13 that the police officer is approaching, and the loudspeaker control unit 133 of the loudspeaker device 13 converts this voice data into a voice signal and outputs it to the speaker 131, so that the route guidance of the above content can be announced at the position of the police officer.

[0094] During the tracking of the position of the police officer, the information processing unit 21 determines whether the police officer has arrived at position P1 (step S57). When the position of the police officer detected by tracking matches or is extremely close to position P1, the information processing unit 21 can determine that the police officer has arrived at position P1.

[0095] When it is determined that the police officer has arrived at position P1 (i.e., the position where the voice seeking help was emitted) (Yes in step S57), the tracking of the police officer is stopped, and the operation of Operation Example 5 is stopped. On the other hand, when 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 device 13, it causes the loudspeaker device 13 that the police officer has approached to announce the route guidance.

[0096] As described above, the position P1 where the first voice is detected and the position P2 where the person related to the first voice exists are specified, the loudspeaker device 13 installed on the route from position P2 to position P1 is specified, and when approaching any of the loudspeaker devices 13 where the person related to the first voice is specified, by causing the loudspeaker device 13 to announce the voice of the route guidance to position P1, the person related to the first voice can be surely guided to position P1. For example, when a voice seeking help such as a scream is emitted, the police officer can be surely guided to position P1 where the voice was emitted.

[0097] (5-7) System operation example 6 Next, using FIG. 18, operation example 6 of system 100 will be described. FIG. 18 is a flowchart showing operation example 6 of system 100. In operation example 6, sensor 111 of sensor device 11 is an acoustic sensor, and when an acoustic sensor detects a voice regarding guidance to a specific location in a predetermined area A, the voice to guide to the above specific location (target location) is amplified for a loudspeaker installed on the path from the installation position of the sensor device 11 having the acoustic sensor that detected the voice to the above specific location.

[0098] In operation example 6, first, when a voice is detected by any one of the plurality of 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). The information processing unit 21 determines whether the detected voice is a voice requesting guidance (step S63). A voice requesting guidance is, for example, a voice having content such as "Please guide me to ○○".

[0099] When it is determined that the voice detected by any one of the sensor devices 11 is a voice requesting guidance (Yes in step S63), the information processing unit 21 identifies the installation position of the sensor device 11 (amplifying sensor device 10) that detected the voice requesting guidance based on the address of the transmission source of the received voice data or the identification information of the sensor device 11 and the sensor device management information I1 (step S64). In addition, the information processing unit 21 analyzes the received voice to identify the target position that the person who requested the guidance wants to go to.

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

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

[0102] Based on the result of the above tracking, the information processing unit 21 determines whether the person who requested the route guidance is approaching any of the voice amplifier devices 13 installed on the route to the target position (step S68). When the person who requested the route guidance is approaching the voice amplifier device 13 (Yes in step S68), the information processing unit 21 causes the voice amplifier device 13 that the person who requested the route guidance is approaching to amplify the route guidance to the target position (step S69). For example, the information processing unit 21 transmits voice data of voice for route guidance such as "Please turn left at the next intersection", "Go 100 m east", "The building across the road is the target position" to the voice amplifier device 13 that the person who requested the route guidance is approaching, and the voice amplification control unit 133 of the voice amplifier device 13 converts this voice data into a voice signal and outputs it to the speaker 131, so that the person who requested the route guidance can be provided with the route guidance of the above content by voice amplification.

[0103] While tracking the position of the person who requested route guidance, the information processing unit 21 determines whether this person has arrived at the target position (step S70). If it is determined that the person who requested route guidance has arrived at the target position (Yes in step S70), the tracking of this person is stopped, and the operation of operation example 6 is stopped. On the other hand, if it is determined that the person who requested route guidance 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 requested route guidance, and when this person approaches the loudspeaker device 13, causes the loudspeaker device 13 that this person has approached to perform route guidance by loudspeaker.

[0104] As described above, when voice regarding route guidance to a specific location in the predetermined area A is detected, for the loudspeaker device installed on the path from the installation position of the sensor device 11 having the acoustic sensor that detected the voice to the target position, by amplifying the voice for performing route guidance until reaching the target position, the person who requested route guidance can be surely guided to the target position that this person wants to go to.

[0105] As described above, in the system 100, sensor information in the predetermined area A is acquired, and a plurality of loudspeaker sensor devices 10 (sensor device 11, loudspeaker device 13) that perform loudspeaker in the predetermined area A are provided on at least a part of a plurality of utility poles P provided in the predetermined area A and / or at least a part of the overhead wires L installed on the plurality of utility poles P. Generally, the utility poles P and the overhead wires L are installed without limit in a predetermined area A where people gather, such as in urban areas and shopping streets. The utility poles P and the overhead wires L are particularly provided along the flow line of people such as roads or in the vicinity thereof. Therefore, by installing the loudspeaker sensor device 10 on the utility pole P and / or the overhead wire L, the loudspeaker sensor device 10 can be easily installed without limit in the predetermined area. In particular, the loudspeaker sensor device 10 can be easily installed without limit at locations that can be the flow line of people, such as roads existing in the predetermined area A, or in the vicinity thereof.

[0106] In system 100, server 20 manages the installation positions of a plurality of voice amplification sensor devices 10 (sensor devices 11, voice amplification devices 13). Server 20 acquires sensor information from any one of the plurality of sensor devices 11 and associates the acquired sensor information with the installation position of the sensor device 11 from which it was acquired. Further, server 20 selects a voice amplification device 13 installed at a specific position or in a partial area within a predetermined area A and issues a command to perform voice amplification to the selected voice amplification device 13. Thereby, server 20 can 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 of performing voice amplification of various voices to people and the like existing in the predetermined area A. For example, services such as operation examples 1 to 6 described above can be provided.

[0107] 2. Second Embodiment (1) Outline The sensor information collected by the sensor device 11 of the system 100 can be utilized for various purposes other than voice amplification from the voice amplification device 13. For example, as shown in FIG. 19, the system 100 outputs the sensor information to another system (referred to as a cooperation system 200) connected via the network N and can perform a cooperation operation with the cooperation system 200. The cooperation system 200 is, for example, a system operated by a service provider that provides services different from those of the system 100 that provides various services by collecting sensor information by the sensor device 11 and performing voice amplification by the voice amplification device 13. FIG. 19 is a diagram showing the configuration of the system in the second embodiment.

[0108] In the second embodiment, the system 100 periodically or irregularly transmits (provides) the sensor information collected and organized based on the above operation examples and the like to the cooperation system 200. The cooperation system 200 executes various services using the sensor information received (provided) from the system 100. In this way, the system 100 can provide the collected and organized sensor information to the outside for the purpose of cooperating with external services. Hereinafter, an example of cooperation between the system 100 and the cooperation system 200 in the second embodiment will be described.

[0109] (2) Collaboration Example 1 System 100 can collaborate with, for example, a collaboration system 200 that provides various services using drones. The collaboration system 200 includes one or more drone ports where drones (unmanned aerial vehicles) take off and land, and flies the drones waiting at the drone ports towards a specific location. The drone has, for example, a cargo transportation mechanism or the like.

[0110] In Collaboration Example 1, based on the operation example 3 described in the first embodiment, after identifying the installation position of the sensor device 11 that detected the first voice, the information processing unit 21 of the server 20 of the system 100 transmits information regarding the identified installation position to the collaboration system 200. The collaboration system 200 sets the installation position of the sensor device 11 received from the system 100 as the landing target of the drone and flies the drone from the drone port. The drone with the landing target set uses the cargo transportation mechanism to fly and transport the materials that are considered highly necessary according to the event that can be grasped from the first voice to the landing target.

[0111] In Collaboration Example 1, the event that can be grasped from the first voice is, for example, the occurrence of a sudden illness. Also, as the materials to be flown and transported by the drone, for example, there is an AED (Automated External Defibrillator).

[0112] Through such collaboration, when there is a person (for example, a person with a sudden illness) in the predetermined area A who needs treatment with an AED, it is possible to quickly assist in the treatment of the person.

[0113] (3) Collaboration Example 2 System 100 can collaborate with, for example, a collaboration system 200 provided in a building or the like within a predetermined area A and that conducts in-building broadcasting within the building premises. This collaboration system 200 includes a sound source (voice data) for in-building broadcasting, an audio amplifier, and one or more speakers. The collaboration system 200 has a function of amplifying the sound source with the audio amplifier and broadcasting it loudly from the speakers.

[0114] In cooperation 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 position of the sensor device 11 that detected the event, and transmits information regarding this installation position to the cooperation system 200. The cooperation system 200 provided in a building existing near the installation position of the sensor device 11 (for example, within a predetermined distance range from the installation position of the sensor device 11) performs a public address broadcast to convey the occurrence of the event detected by the sensor device 11 within the precincts of the building. In cooperation example 2, the event is, for example, the occurrence of a fire, an accident, an incident, or the like.

[0115] By such cooperation, when an event that should be made known to people occurs within a predetermined area A, not only can information be transmitted to people outdoors by the public address device 13, but information can also be transmitted to people in nearby buildings using the cooperation system 200.

[0116] (4) Cooperation example 3 The system 100 can cooperate with a cooperation system 200 that provides a real estate service for appraising the value of land based on an area environment such as noise. This cooperation system 200 is, for example, a system in which a real estate agent manages properties.

[0117] In cooperation example 3, the information processing unit 21 of the server 20 of the system 100 transmits information regarding the sound pressure distribution within a predetermined area A generated based on operation example 1 described in the first embodiment to the cooperation system 200. The cooperation system 200 grasps the noise level within the predetermined area A from the received information on the sound pressure distribution (noise level), and can utilize it for visualizing the noise situation in the area where the managed properties within the predetermined area A exist and for appraising the land.

[0118] (5) Cooperation example 4 System 100 can be linked with a cooperation system 200 of an organization such as a government agency that conducts urban planning, etc. In cooperation example 4, the information processing unit 21 of the server 20 of system 100 transmits information regarding the sound pressure distribution within a predetermined area A generated based on operation example 1 described in the first embodiment to the cooperation system 200. It provides to the cooperation system 200. The cooperation system 200 can grasp the urban environment within the predetermined area A from the received information regarding the sound pressure distribution and utilize it for decision-making on urban planning and environmental policies.

[0119] (6) Cooperation example 5 System 100 can be linked with a cooperation system 200 that conducts taxi dispatching and advertisement provision, etc. In cooperation example 5, the information processing unit 21 of the server 20 of system 100 transmits information regarding the sound pressure distribution within a predetermined area A generated based on operation example 1 described in the first embodiment to the cooperation system 200. The cooperation system 200 can grasp the density of people and the bustling state within the predetermined area A from the information regarding the sound pressure distribution and utilize it for formulating a taxi dispatching plan and an advertisement provision plan.

[0120] (7) Cooperation example 6 System 100 can be linked with a cooperation system 200 that monitors traffic conditions and controls traffic signals when emergency vehicles are traveling. In cooperation example 6, the information processing unit 21 of the server 20 of system 100 transmits information regarding the sound pressure distribution within a predetermined area A generated based on operation example 1 described in the first embodiment to the cooperation system 200. The cooperation system 200 can grasp the traffic conditions within the predetermined area A from the information regarding the sound pressure distribution and utilize it for visualizing the traffic conditions and traffic signal control.

[0121] 3. Other embodiments As described above, one embodiment of the present disclosure has been explained, but the present disclosure is not limited to the above embodiment, and various modifications are possible. In particular, the plurality of embodiments and modification examples described in this specification can be arbitrarily combined as needed.
