[0016] The present disclosure proposes an information processing device, an information processing system, and an information processing method that can reduce the cost of determining the soundness of a building. Hereinafter, an information processing device 100, an information processing system including the information processing device 100, and an information processing method performed by the information processing device 100 according to an embodiment will be described with reference to FIGS.
[0017] [Embodiment] [1. System configuration example] First, an overview of an information processing system according to an embodiment will be described with reference to Fig. 1. Fig. 1 is a diagram showing an example of the configuration of the information processing system according to the embodiment. As shown in Fig. 1, the information processing system according to the embodiment includes a terminal device 10, a gateway 20, a plurality of lighting devices 30, a plurality of acceleration sensors 40, and an information processing device 100.
[0018] The terminal device 10 controls each lighting device 30 in accordance with operations by an operator. The terminal device 10 corresponds to, for example, any information processing terminal such as a smartphone, a tablet terminal, or a PC (Personal Computer), or a dimming control console. The terminal device 10 is used by an operator who investigates the soundness of the building BL.
[0019] The terminal device 10 may have various functions such as a communication function, a display function, and a web browsing function. In this case, the terminal device 10 may be equipped with a dedicated application program (hereinafter referred to as a "dedicated app") that provides various functions for controlling the lighting device 30. An operator of the terminal device 10 can display a screen of the dedicated app on the terminal device 10 and perform various operations for controlling the lighting device 30 through the displayed screen.
[0020] The terminal device 10 can connect to the external network N1 by wire or wirelessly using a communication function, and can communicate with the information processing device 100 and the terminal device 10 via the external network N1 in both directions.
[0021] The external network N1 may include a public network such as the Internet, a telephone network, or a satellite communication network, or a wide area network (WAN). The external network N1 may also include a dedicated network such as an IP-VPN (Internet Protocol-Virtual Private Network). The external network N1 may also include a wireless communication network such as Wi-Fi (registered trademark) or Bluetooth (registered trademark).
[0022] The terminal device 10 can receive, for example, information regarding the evaluation of the soundness of the building BL from the information processing device 100. The operator of the terminal device 10 can confirm the information regarding the evaluation of the soundness of the building BL displayed on the terminal device 10.
[0023] The gateway 20 is connected to an external network N1 and an internal network N2. The internal network N2 is, for example, a LAN (Local Area Network) such as Ethernet (registered trademark) constructed inside the building BL. The internal network N2 may also include wireless communication networks such as Wi-Fi (registered trademark) and Bluetooth (registered trademark). The internal network N2 is an example of a "communication network."
[0024] The gateway 20 receives information from the terminal device 10 or the information processing device 100 via the external network N1 and transmits the information to the lighting device 30 via the internal network N2. The gateway 20 also receives information from the lighting device 30 via the internal network N2 and transmits the information to the terminal device 10 or the information processing device 100 via the external network N1.
[0025] The lighting device 30 is a lighting device that is permanently installed on a structure such as the ceiling of the building BL, a wall near the ceiling, a pillar, a wall, a foundation, foundation piles, or a diagonal member (e.g., a brace). In the information processing according to the embodiment, the structure to which the lighting device 30 is attached is preferably a pillar that can be recognized at a glance. The lighting device 30 is, for example, a ceiling light, a downlight, or an emergency light. The lighting device 30 can communicate bidirectionally with the terminal device 10 in accordance with DALI (Digital Addressable Lighting Interface) (registered trademark) or various wired or wireless communication standards. The lighting device 30 may operate using power supplied from a commercial power source, or may operate in an emergency such as an earthquake using power stored in an emergency power source (i.e., a battery) installed in the lighting device itself or in an emergency such as an earthquake.
[0026] Furthermore, the terminal device 10 and the lighting device 30 can perform wireless communication in accordance with communication standards such as Bluetooth (registered trademark) and BLE (Bluetooth (registered trademark) Low Energy).
[0027] The acceleration sensor 40 detects acceleration. The acceleration sensor 40 is connected to the lighting device 30, for example, by a plug-in. The acceleration sensor 40 outputs acceleration information relating to the detected acceleration to the lighting device 30.
[0028] The information processing device 100 executes information processing according to the embodiment described below. For example, when seismic motion is observed, the information processing device 100 acquires acceleration information related to acceleration detected by an acceleration sensor via the lighting device 30, and calculates an index value for evaluating the soundness of the building BL based on the acquired acceleration information. In this way, the information processing device 100 can collect acceleration information from the lighting device 30 via the existing internal network N2 to which the lighting device 30 is connected, and can therefore calculate an index value for determining the soundness of the building BL while reducing the cost required for installing a communication network for collecting acceleration information.
[0029] The information processing device 100 is typically a server device, but may also be realized by a mainframe, a workstation, etc. Furthermore, when the information processing device is configured by a server device, it may be realized by a single server device, or may be realized by a cloud system in which multiple server devices and multiple storage devices operate in cooperation with each other.
[0030] [2. Equipment configuration] [2-1. Example of lighting equipment configuration] An example of the functional configuration of the lighting device 30 according to the embodiment will be described below with reference to Fig. 2. Fig. 2 is a diagram showing an example of the functional configuration of the lighting device 30 according to the embodiment. The lighting device 30 according to the embodiment has a communication unit 31, a connection unit 32, a lighting unit 33, a storage unit 34, and a control unit 35.
[0031] (Communications Department 31) The communication unit 31 transmits and receives information to and from other devices. For example, the communication unit 31 passes a control signal received from the terminal device 10 to the control unit 35. The communication unit 31 also passes a request from the information processing device 100 to the control unit 35.
[0032] The communication unit 31 may be realized by, for example, a predetermined communication circuit or a network interface card (NIC). The communication unit 31 may support any communication method. The communication methods supported by the communication unit 31 may include communication methods based on wireless communication methods such as wireless LAN, Bluetooth (registered trademark), BLE (Bluetooth (registered trademark) Low Energy), and infrared communication.
[0033] (Connection 32) The connection unit 32 includes a power supply terminal such as a DC input terminal for supplying power to the lighting device 30, and a connection terminal such as a USB (Universal Serial Bus) terminal for plugging in an external device such as the acceleration sensor 40.
[0034] Electric power for operating the lighting device 30 is supplied via a connection unit 32 (for example, a DC input terminal) from a power supply circuit that takes in power from a commercial power source, which is an AC power source, and converts it into DC power, or from an emergency power source.
[0035] Furthermore, the power for operating the lighting device 30 is also supplied to the acceleration sensor 40 connected to the connection unit 32 (for example, a USB terminal). The acceleration sensor 40 can operate using the power supplied from the lighting device 30. This eliminates the need for facility costs for supplying power to the acceleration sensor 40, thereby reducing the cost of determining the soundness of a building. Furthermore, the connection unit 32 passes the acceleration information input from the acceleration sensor 40 to the control unit 35.
[0036] (Lighting Department 33) The lighting unit 33 includes a light source such as an LED (Light Emitting Diode) or a fluorescent lamp, and illuminates each floor of the building BL. The lighting unit 33 turns on and off in accordance with a control signal input from the control unit 35, for example. Such a control signal is transmitted from the terminal device 10 in response to an operation by an operator of the terminal device 10, for example.
[0037] (Storage unit 34) The storage unit 34 stores various types of information. For example, the storage unit 34 can store programs and data for implementing various controls executed by the control unit 35. The storage unit 34 can be realized by, for example, a semiconductor memory element such as a random access memory (RAM) or a flash memory, or a storage device such as a hard disk or an optical disk. Furthermore, when the storage unit 34 is realized by a flash memory, it may be implemented by a removable, portable recording medium such as an SD (Secure Digital) card.
[0038] The storage unit 34 may store a dedicated application having a function for executing the information processing according to the embodiment. The storage unit 34 may also store various programs and data according to the purpose. The storage unit 34 stores, for example, acceleration information input from the acceleration sensor 40.
[0039] (Control unit 35) The control unit 35 is, for example, a control circuit (i.e., a controller) that controls each part of the lighting device 30, and has an internal memory for storing programs that define various processing procedures and required data, and executes various processes using these. The control unit 35 can be realized by a microcomputer or the like. The microcomputer is equipped with a processor such as a CPU (Central Processing Unit) or an MPU (Micro Processing Unit), and a storage device such as a ROM (Read Only Memory) or RAM.
[0040] The ROM stores programs for controlling each part of the lighting device 30 and application programs (for example, dedicated apps) for executing various processes. A processor such as a CPU executes the programs and apps stored in the ROM, thereby enabling the microcomputer to control the lighting device 30 and realize various functions.
[0041] The RAM is used as a memory area required for a processor such as a CPU to execute calculations. The control unit 35 may control the lighting device 30 and perform various functions by reading and executing programs stored in the storage unit 34. The control unit 35 may also be implemented by an integrated circuit such as an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), or an SoC (System-on-a-chip).
[0042] For example, the control unit 35 inputs a control signal from the terminal device 10 to the lighting unit 33. The lighting device 30 may be equipped with an emergency power supply. In this case, when the power supply from the commercial power source is cut off, the control unit 35 operates using the emergency power supply that is installed in advance, and supplies power from the emergency power supply to the acceleration sensor 40.
[0043] Furthermore, the control unit 35 stores the acceleration information input from the acceleration sensors 40 in the storage unit 34 in response to a request from the information processing device 100. For example, the control unit 35 starts recording the acceleration information in response to a request to acquire acceleration information transmitted from the information processing device 100. The control unit 35 detects vibrations of the building BL based on the acceleration information and determines whether a predetermined seismic movement is continuing based on the detected vibration. The control unit 35 continues recording the acceleration information while the predetermined seismic movement continues. At this time, when recording the acceleration information, the control unit 35 synchronizes the acceleration information input from each of the acceleration sensors 40.
[0044] For example, the control unit 35 of each lighting device 30 is synchronized in advance with absolute time using a network protocol such as NTP (Network Time Protocol). Then, when transmitting acceleration information from the acceleration sensor 40 to the information processing device 100, the control unit 35 includes absolute time information in the acceleration information and transmits it to the information processing device 100. The information processing device 100 synchronizes the acceleration information received from the plurality of lighting devices 30 based on the absolute time information included in the acceleration information. Meanwhile, when the information processing device 100 receives acceleration information from each lighting device 30, the information processing device 100 may synchronize the acceleration information received from the plurality of lighting devices 30 by storing the information including time equivalent information held by the information processing device 100 (which may be, for example, absolute time or internal information that counts up over time).
[0045] In addition, when the control unit 35 determines that the specified seismic motion is not continuing (i.e., when it determines that the specified seismic motion has subsided), it stops recording the acceleration information and transmits the acceleration information recorded in the memory unit 34 to the information processing device 100 via the communication unit 31.
[0046] The lighting device 30 may be equipped with a seismic intensity meter. In this case, the lighting device 30 can determine whether a predetermined earthquake motion is continuing by determining whether the measurement value of the seismic intensity meter exceeds a predetermined threshold.
[0047] [2-2. Example of configuration of information processing device] An example of the functional configuration of the information processing device 100 according to the embodiment will be described below with reference to Fig. 3. Fig. 3 is a diagram showing an example of the functional configuration of the information processing device 100 according to the embodiment. The information processing device 100 according to the embodiment has a communication unit 110, a storage unit 120, and a control unit 130.
[0048] (Communication unit 110) The communication unit 110 transmits and receives information to and from other devices. The communication unit 110 transmits requests obtained from the control unit 130 to the lighting device 30. The communication unit 110 also passes, for example, acceleration information received from the lighting device 30 to the control unit 130.
[0049] The communication unit 110 may be realized by, for example, a predetermined communication circuit or a network interface card (NIC). The communication unit 110 may support any communication method. The communication methods supported by the communication unit 110 may include communication methods based on wireless communication methods such as wireless LAN, Bluetooth (registered trademark), BLE (Bluetooth (registered trademark) Low Energy), and infrared communication.
[0050] (Storage unit 120) The storage unit 120 stores various types of information. For example, the storage unit 120 can store programs and data for implementing various controls executed by the control unit 130. The storage unit 120 can be realized by, for example, a semiconductor memory element such as a random access memory (RAM) or a flash memory, or a storage device such as a hard disk or an optical disk. Furthermore, when the storage unit 120 is realized by a flash memory, it may be implemented by a removable, portable recording medium such as an SD (Secure Digital) card.
[0051] The storage unit 120 may store a dedicated application having a function for executing information processing according to the embodiment. The storage unit 120 may also store various programs and data according to purposes. The storage unit 120 includes, for example, a placement information storage unit 121 as shown in FIG. 3 .
[0052] (Placement information storage unit 121) The placement information storage unit 121 stores placement information regarding the placement of lighting devices 30 to which acceleration sensors 40 that detect acceleration information for calculating index values for evaluating the soundness of a building BL are connected. Fig. 4 is a diagram illustrating an overview of the placement information stored in the placement information storage unit 121 according to the embodiment.
[0053] 4, the placement information stored in the placement information storage unit 121 has multiple items such as a "floor" item, a "lighting unit nearest to the building structure" item, a "corresponding lighting unit on the floor directly below" item, and a "height" item. These items in the placement information are associated with each other.
[0054] The "floor" item stores information for identifying each floor of the building BL. For example, the "floor" item stores the floor number of each floor.
[0055] The "lighting closest to the building structure" item stores information for identifying the lighting device 30 installed closest to the building structure of the building BL (hereinafter referred to as "lighting closest to the building structure"). The building structure corresponds to, for example, a pillar or a beam. The lighting closest to the building structure is less susceptible to noise other than seismic motion, such as shaking caused by people moving between floors of the building BL.
[0056] The "light closest to the building structure" item stores, for example, identification information unique to the light closest to the building structure. The information stored in the "light closest to the building structure" item is registered in advance by an administrator of the information processing device 100. The control unit 130 handles the acceleration information transmitted from the light closest to the building structure as acceleration information detected by an acceleration sensor installed at the position closest to the building structure, and executes processing.
[0057] The "Corresponding lighting on the floor directly below" item stores information for identifying the lighting device 30 (hereinafter referred to as "corresponding lighting") that pairs with the lighting closest to the structure when calculating the inter-storey displacement of the building BL, from among multiple lighting devices installed on the floor directly below the floor on which the lighting closest to the structure is installed.
[0058] The "light closest to the building structure" field stores, for example, identification information unique to the corresponding light. The information stored in the "corresponding light on the floor directly below" field is registered in advance by the administrator of the information processing device 100. When calculating the inter-story displacement of the building BL, the control unit 130 handles the acceleration information transmitted from the corresponding light as the other acceleration information paired with the acceleration information detected by the acceleration sensor installed at the position closest to the building structure, and performs processing.
[0059] The administrator of the information processing device 100 may also make the selection based on the tolerance for deviation in the Z-axis direction (see FIG. 5, for example) between the position of the lighting closest to the building structure and the position of the corresponding lighting, that is, the height direction of the floor of the building BL. The tolerance may be set for each floor.
[0060] The "height" item stores information indicating the height of each floor of the building BL. The information indicating the height stored in the "height" item is used in the calculation process of the index value in the calculation unit 132, which will be described later.
[0061] Furthermore, the arrangement information storage unit 121 may store, as arrangement information regarding the arrangement of the lighting devices 30, information indicating the positional relationship between the building frames provided on each floor and the lighting devices 30 installed on each floor.
[0062] (control unit 130) The control unit 130 is, for example, a control circuit (i.e., a controller) that controls each unit of the information processing device 100, and has an internal memory for storing programs that define various processing procedures and required data, and executes various processes using these. The control unit 130 can be realized by a microcomputer or the like. The microcomputer is equipped with a processor such as a CPU (Central Processing Unit) or an MPU (Micro Processing Unit), and a storage device such as a ROM (Read Only Memory) or RAM.
[0063] The ROM stores programs for controlling each unit of the information processing device 100 and application programs (for example, dedicated applications) for executing various processes. A processor such as a CPU executes the programs and applications stored in the ROM, thereby realizing control of the information processing device 100 by a microcomputer and various functions.
[0064] The RAM is used as a memory area necessary for a processor such as a CPU to execute calculations. The control unit 130 may control the information processing device 100 and perform various functions by reading programs stored in the storage unit 120 and executing the read programs. The control unit 130 may also be implemented by an integrated circuit such as an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), or an SoC (System-on-a-chip).
[0065] As shown in Fig. 3, the control unit 130 has a collection unit 131, a calculation unit 132, and a determination unit 133. The control unit 130 uses these units to realize or execute functions and actions of information processing according to the embodiment described below. Note that the internal configuration of the control unit 130 is not limited to the configuration shown in Fig. 3, and may be any other configuration as long as it performs the information processing described below, or may have a different configuration in accordance with expansion or modification of functions.
[0066] (Collection Department 131) The collection unit 131 collects acceleration information detected by multiple sensors installed within a predetermined range from the structure on each floor of the building BL to be evaluated, the acceleration sensors 40 being installed together with the lighting devices 30, via an internal network N2 (an example of a "communication network") to which the multiple lighting devices 30 are connected.
[0067] For example, the collection unit 131 collects acceleration information when seismic motion is observed. Specifically, when the collection unit 131 receives an earthquake alert, the collection unit 131 transmits an acceleration information acquisition request to the lighting device 30 via the communication unit 110. Then, the collection unit 131 receives the acceleration information transmitted from the lighting device 30 via the internal network N2 from the communication unit 110.
[0068] This allows the collection unit 131 to collect acceleration information from the lighting device 30 through the existing internal network N2 to which the lighting device 30 is connected, eliminating the cost required for installing a communication network to collect acceleration information and reducing the cost of determining the soundness of a building.
[0069] The information processing device 100 may include a seismic intensity meter. In this case, the collection unit 131 can determine whether a predetermined earthquake motion has been observed by determining whether the measurement value of the seismic intensity meter exceeds a predetermined threshold.
[0070] (Calculation unit 132) The calculation unit 132 calculates an index value for evaluating the soundness of the building BL based on the acceleration information collected by the collection unit 131.
[0071] For example, based on the placement information regarding the placement of the lighting devices 30, the calculation unit 132 identifies, for each floor, the acceleration information detected by each of the acceleration sensors 40 installed at the position closest to the main structure, calculates the horizontal inter-story displacement occurring on each floor using the identified acceleration information, and calculates the inter-story deformation angle, which is an index value, using the calculated inter-story displacement and the height of each floor.
[0072] Hereinafter, a method for calculating the inter-story deformation angle by the calculation unit 132 will be specifically described with reference to Fig. 5. The inter-story deformation angle is determined as the ratio of the inter-story displacement δ, which is the horizontal displacement caused on each floor FL by seismic force, to the inter-story height h, which is the height of each floor. Fig. 5 is an explanatory diagram for explaining an overview of the method for calculating the inter-story deformation angle according to the embodiment.
[0073] For example, a case will be described in which an inter-story deformation angle between the first floor and the second floor of a building BL is calculated. The calculation unit 132 identifies acceleration information transmitted from the lighting closest to the building structure of the second floor from among the acceleration information collected by the collection unit 131. The calculation unit 132 also identifies acceleration information transmitted from a corresponding lighting that is paired with the lighting closest to the building structure of the second floor on the first floor, which is the floor directly below the second floor.
[0074] The calculation unit 132 also obtains the amount of displacement of the second floor by integrating acceleration information transmitted from the lighting closest to the building frame on the second floor, and obtains the amount of displacement of the first floor by integrating acceleration information transmitted from the corresponding lighting on the first floor. The calculation unit 132 also calculates the horizontal inter-story displacement δ occurring between the first and second floors by finding the difference between the amount of displacement of the second floor and the amount of displacement of the first floor.
[0075] In addition, the calculation unit 132 may selectively use, as the inter-story displacement δ, the larger of the displacement in the X-axis direction and the displacement in the Y-axis direction that define the planar direction of each floor, or may use a composite displacement amount that is a combination of the displacement in the X-axis direction and the displacement in the Y-axis direction.
[0076] After calculating the inter-story displacement δ, the calculation unit 132 calculates the inter-story deformation angle using the inter-story displacement δ and the inter-story height h, which is the height of the relevant floor, according to the following formula (1). The calculation unit 132 passes the calculated inter-story deformation angle to the determination unit 133.

[0081] [3. Processing Procedure] (3-1. Processing by lighting equipment) The flow of processing by the lighting device 30 according to the embodiment will be described below. Fig. 6 is a flowchart showing an example of a processing procedure by the lighting device 30 according to the embodiment. The processing procedure shown in Fig. 6 is executed by the control unit 35 included in the lighting device 30.
[0082] As shown in FIG. 6, when an earthquake motion is observed, the control unit 35 records acceleration information while a predetermined earthquake motion continues (step S101).
[0083] Furthermore, the control unit 35 transmits the recorded acceleration information to the information processing device 100 via the communication unit 31 (step S102), and the processing procedure shown in FIG. 6 ends.
[0084] (3-2. Processing by Information Processing Device) A predetermined flow of processing by the information processing device 100 according to the embodiment will be described below with reference to Fig. 7. Fig. 7 is a flowchart showing an example of a processing procedure by the information processing device 100 according to the embodiment. The processing procedure shown in Fig. 7 is executed by the control unit 130 included in the information processing device 100.
[0085] As shown in FIG. 7, the collection unit 131 collects acceleration information detected by the acceleration sensor 40 (step S201).
[0086] Furthermore, the calculation unit 132 calculates an index value for evaluating the soundness of the building based on the acceleration information collected by the collection unit 131 (step S202).

[0088] [4. Other] (4-1. Calculation of inter-story displacement) In the above embodiment, the information processing device 100 may estimate the inter-story displacement based on image information recorded by the lighting device 30 while a predetermined seismic motion is being observed. For example, the information processing device 100 collects image information from the lighting device 30, analyzes the collected image information, and extracts singular points contained in the image information. Then, the information processing device 100 can estimate the inter-story displacement by determining the time-series change in the amount of movement of the extracted singular points.
[0089] (4-2. Calculation of story drift angle) In the above embodiment, an example has been described in which an index value for evaluating the soundness of a building BL is calculated in response to the observation of seismic motion in the information processing system illustrated in Fig. 1, but the present invention is not particularly limited to this example. For example, in the information processing system illustrated in Fig. 1, an index value for evaluating the soundness of a building BL may be calculated in response to the detection of a predetermined vibration in the building BL. This allows the information processing device 100 to provide an operator operating the terminal device 10 with information for evaluating the soundness of the building BL in response to factors other than seismic motion, such as strong winds.
[0090] (4-3. Distortion in the vertical direction) In the above embodiment, the information processing device 100 may calculate the distortion in the height direction based on the acceleration information. For example, when calculating the distortion in the height direction between the first floor and the second floor, the information processing device 100 may calculate the difference between the amount of movement in the Z-axis direction of the first floor and the amount of movement in the Z-axis direction of the second floor.
[0091] Furthermore, a dedicated app for realizing the information processing executed by the lighting device 30 according to the above embodiment may be stored in a computer-readable recording medium such as an optical disk, a semiconductor memory, a magnetic tape, or a flexible disk and distributed. In this case, for example, the lighting device 30 installs the dedicated app read from the recording medium and executes the above-mentioned information processing.
[0092] The dedicated app may be stored in a disk device provided in a server device or cloud system on a network such as the Internet, and may be downloaded to the lighting device 30. The functions realized by the dedicated app may be realized by a collaboration between an OS (Operating System) and application software. In this case, the parts other than the OS may be stored on a medium and distributed, or may be stored in a server device or cloud system and downloaded to the lighting device 30.
