DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0009] A lighting control system (1) of the embodiment includes a lighting system (10) and an analysis device (30). The lighting system (10) has a lighting fixture (12), a memory (15b), a first processor (15a), and a first communication interface (15c, 25).

The first communication interface (15c, 25) outputs lighting operation information indicating a control result for the lighting fixture. The analysis device (30) has a second communication interface (34), a data memory (33), and a second processor (31). The second communication interface (34) receives the lighting operation information and task content information indicating a task performed by a person in the lighting area of the lighting fixture (12). The data memory (33) stores the lighting operation information and the task content information. The second processor (31) outputs to the lighting system (10) lighting control proposal content for the lighting fixtures (12) in accordance with the actual operation of the lighting area, which is created based on the lighting operation information and the work content information stored in the data memory (33). This allows the lighting control system (1) to propose lighting control for the lighting fixtures (12) in accordance with the actual operation including the work content that was being performed in the lighting area of the lighting fixtures (12).
[0010] In the lighting control system (1) of the embodiment, the first processor (15a) of the lighting system (10) updates the lighting control setting information stored in the memory (15b) in response to the lighting control proposal output from the analysis device (30). This allows the lighting control system (1) to update the lighting control setting information for the lighting fixture (12) in response to the lighting control proposal in accordance with actual operation including the work performed in the lighting area of the lighting fixture (12).
[0011] The lighting control system (1) of the embodiment further includes a brightness detection means (14) that detects brightness in the lighting area of the lighting fixture (12). The lighting operation information includes information indicating the brightness detected by the brightness detection means (14). The first processor (15a) controls the lighting fixture (12) based on the brightness detected by the brightness detection means in accordance with the lighting control setting information. This allows the lighting control system (1) to propose lighting control for the lighting fixture (12) in accordance with the proposed lighting control in accordance with the actual operation indicated by the brightness in the lighting area of the lighting fixture (12) and the work content.
[0012] The lighting control system (1) of the embodiment further includes a camera (13) that captures an image of a shooting range including the lighting area of the lighting fixture (12). The first processor (15a) of the lighting system (10) estimates an operation performed by a person in the lighting area of the lighting fixture (12) from the image captured by the camera (13) and outputs the estimation result to the analysis device (30) as operation content information. This allows the lighting control system (1) to estimate the operation content performed by a person in the lighting area of the lighting fixture (12) from the image captured by the camera (13) that captures the shooting range including the lighting area of the lighting fixture (12), and to propose lighting control for the lighting fixture (12) according to the lighting control proposal according to the actual operation including the operation content as the estimation result.
[0013] In the lighting control system (1) of the embodiment, the first processor of the lighting system further recognizes the type and position of fixtures present in the lighting area of the lighting fixture from the captured image taken by the camera, and outputs the recognition result to the analysis device (30) as fixture information. The data memory (33) further stores the fixture information. The second processor (31) outputs to the lighting system (10) a proposal for a fixture layout in accordance with the actual operation of the lighting area, which is created based on the lighting operation information, the work content information, and the fixture information stored in the data memory (33). In this way, the lighting control system (1) can further recognize the type and position of fixtures present in the lighting area of the lighting fixture (12) from the captured image taken by the camera (13), and can propose a fixture layout in accordance with the actual operation indicated by the fixture information and the work content as the recognition result.
[0014] In the lighting control system (1) of the embodiment, the lighting system (10) includes a lighting device (11) including the lighting fixture (12) and the camera (13). This allows the lighting control system (1) to propose lighting control for the lighting device (12) that corresponds to the actual operation in the lighting area of the lighting fixture (12) to the lighting device (11) including the lighting fixture (12) and the camera (13).
[0015] In the lighting control system (1) of the embodiment, the second processor (31) generates display data for displaying a 3D image showing the proposed content using BIM data of the building in which the lighting fixture (12) is installed. This allows the lighting control system (1) to present the proposed content according to the actual operation of the lighting fixture (12) in the lighting area by displaying it using a 3D image of the building.
[0016] The analysis device (30) of the embodiment includes a communication interface (34), a data memory (33), and a processor (31). The communication interface (34) receives lighting operation information indicating a control result for a lighting fixture (12) and task content information indicating a task performed by a person in the lighting area of the lighting fixture (12). The data memory (33) stores the lighting operation information and the task content information. The processor (31) creates a proposed content of lighting control for the lighting fixture (12) in accordance with the actual operation of the lighting area based on the lighting operation information and the task content information stored in the data memory (33), and outputs the proposed content to a lighting system (10) including a control unit (15) that controls the lighting fixture (12). This allows the analysis device (30) to propose lighting control for the lighting fixture (12) in accordance with the actual operation including the task content performed in the lighting area of the lighting fixture (12) in the lighting system (10).
[0017] The operation method of the lighting control system (1) of the embodiment controls a lighting fixture (12) based on lighting control setting information, outputs lighting operation information indicating a control result for the lighting fixture (12), stores the lighting operation information and task content information indicating a task performed by a person in the lighting area of the lighting fixture (12) in a data memory (33), and outputs a proposed content of lighting control for the lighting fixture (12) that is tailored to the actual operation of the lighting area, which is created based on the lighting operation information and the task content information stored in the data memory (33). Thus, according to the operation method of the lighting control system (1), it is possible to propose lighting control for the lighting fixture (12) that is tailored to the actual operation including the task content that was performed in the lighting area of the lighting fixture (12).
[0018] Hereinafter, embodiments will be described with reference to the drawings. Fig. 1 is a diagram for explaining an outline of a configuration example of a lighting control system 1 according to an embodiment, and Fig. 2 is a diagram showing an external configuration example of a camera-equipped lighting device 11 in the lighting control system 1 according to the embodiment. As shown in FIG. 1, the lighting control system 1 has a lighting system 10 and an analysis device 30. The lighting system 10 is composed of a plurality of camera-equipped lighting devices 11 and a lighting control device 20. The configuration of the lighting control system 1 is not limited to the example configuration shown in FIG. 1. For example, the lighting control system 1 may be composed of a plurality of camera-equipped lighting devices 11 as the lighting system 10 and an analysis device 30'. Such a lighting control system can be realized by providing the functions of the lighting control device 20, which will be described later, in either the analysis device 30 or the control unit 15 (see FIG. 3) of the camera-equipped lighting device 11.
[0019] As shown in Fig. 2, the camera-equipped lighting device 11 is a lighting device equipped with a lighting fixture 12, a camera 13, a sensor 14, and a control unit 15 (see Fig. 3). The lighting fixture 12 is set to irradiate a predetermined lighting area with illumination light. The camera 13 captures an image of a shooting range including the lighting area of the lighting fixture 12. The sensor 14 detects the brightness in the lighting area of the lighting fixture 12, the presence or absence of people, and other conditions.
[0020] Note that the lighting fixtures 12, cameras 13 and sensors 14 in the lighting control system 1 are not limited to being integrally formed as the camera-equipped lighting device 11, and the lighting fixtures 12, cameras 13 and sensors 14 may each be independent devices. However, the lighting control system 1 described below will be described assuming a form in which the camera-equipped lighting device 11, which includes the lighting fixtures 12, cameras 13 and sensors 14, is installed in various locations in the lighting space to be illuminated, such as an office or factory.
[0021] The lighting control device 20 communicates with each camera-equipped lighting device 11 installed in each location in a building that serves as an illuminated space, for example, via a local area network (LAN) or the like. The lighting control device 20 also communicates with an analysis device 30 via a network interface. The lighting control device 20 is an information processing device (computer) that can execute application programs, such as a personal computer (PC), a server device, a tablet PC, or a smartphone.
[0022] As a function of the lighting system 10, the lighting control device 20 instructs each camera-equipped lighting device 11 to set lighting control. For example, when applying a lighting control method proposed by the analysis device 30, the lighting control device 20 instructs the camera-equipped lighting devices 11 including the lighting fixtures 12 to be controlled by the applied lighting control method to set lighting control in accordance with the lighting control method. As a result, the camera-equipped lighting device 11 updates the lighting control setting information for the lighting fixtures 12 to setting information in accordance with the lighting control method.
[0023] Furthermore, the lighting control device 20 acquires various types of information from each camera-equipped lighting device 11. For example, the lighting control device 20 acquires information indicating the lighting control results of the camera-equipped lighting device 11 on the lighting fixtures 12 (lighting operation information) and information such as images captured by the camera 13. The lighting control device 20 supplies the lighting operation information acquired from the camera-equipped lighting device 11 to the analysis device 30.
[0024] Furthermore, the lighting control device 20 executes image analysis processing on the image captured by the camera 13, and supplies information indicating the results of the image analysis to the analysis device 30. For example, the lighting control device 20 estimates (recognizes) the work (task) being performed by a person (worker) present in the lighting area of the lighting fixture 12 (the shooting range of the camera 13) from the image captured by the camera 13, and supplies the estimation result as work content information to the analysis device 30. Furthermore, the lighting control device 20 recognizes the type and position of fixtures present in the lighting area of the lighting fixture 12 from the image captured by the camera 13, and supplies the recognition result to the analysis device 30 as fixture information.
[0025] Analysis device 30 collects various information related to the operation of lighting system 10 from lighting system 10. According to the configuration shown in Fig. 1, analysis device 30 communicates with lighting control device 20 and receives various information on lighting system 10 from lighting control device 20. Analysis device 30 analyzes the information collected from lighting system 10 to propose a lighting control method for lighting fixtures 12, a layout change in the lighting area of lighting fixtures 12, or replacement of parts such as consumables in lighting system 10.
[0026] The analysis device 30 also holds Building Information Modeling (BIM) data. The BIM data held by the analysis device 30 is modeled information about a building as a lighting space in which the lighting fixtures 12 of the lighting system 10 are installed. For example, the BIM data includes design data indicating the arrangement and orientation of walls, doors, windows, and the like in a building. The analysis device 30 also holds information such as the installation positions and installation orientations of the lighting fixtures 12, cameras 13, and sensors 14 in the lighting system 10 as BIM data.
[0027] The analysis device 30 also acquires lighting operation information indicating the lighting control results of the lighting fixtures 12 from the lighting system 10 that is actually in operation. The analysis device 30 also acquires information from the lighting system 10, such as task information indicating the tasks performed by people in the lighting area and fixture information indicating the types and arrangement of fixtures, which are obtained as a result of image analysis of images captured by the camera 13 that captures the shooting range including the lighting area of the lighting fixtures 12.
[0028] The analysis device 30 accumulates information such as lighting operation information, work content information, and fixture information obtained from the lighting system 10. The analysis device 30 creates proposal content indicating a lighting control method for each lighting fixture 12 in the lighting system 10, a layout of the lighting area of the lighting fixtures 12, or a proposal for part replacement, etc., from the accumulated information, and outputs the created proposal content to the lighting control device 20.
[0029] Next, a detailed description will be given of the configuration of the camera-equipped lighting device 11 in the lighting control system 1 according to this embodiment. 2, the camera-equipped lighting device 11 is directly attached to an installation surface, for example, a ceiling surface. The camera-equipped lighting device 11 as a lighting device is a long base light whose light-emitting area is continuous along the longitudinal direction.
[0030] In the configuration example shown in Figure 2, the camera-equipped lighting device 11 comprises a fixture body, a lighting fixture (light source unit) 12 that is detachably attached to the fixture body, and auxiliary equipment including a camera 13 and a sensor 14 that are attached to one end of the fixture body.
[0031] As shown in Fig. 2, the device body is made of, for example, sheet metal and is formed long. The device body has a top plate portion which is a long installation portion, side plate portions provided on both sides in the short direction of the top plate portion, and end plate portions provided on both ends in the longitudinal direction of the top plate portion, and is formed in a long and narrow box shape with an opening on the lower side which is the front side.
[0032] Also arranged within the fixture body are a light source power supply section which is the power source for lighting fixture 12, and an auxiliary equipment power supply section which is the power source for camera 13, sensor 14, etc. The light source power supply section is, for example, an AD-DC converter, and converts AC power from a commercial AC power source into DC power, which is the lighting power required to light the light source of lighting fixture 12. Lighting fixture 12 lights the light source with the power supplied from the light source power supply section. The auxiliary equipment power supply section is, for example, an AD-DC converter, and converts AC power from a commercial AC power source into DC power, which is the operating power required to operate camera 13 and sensor 14. Camera 13 and sensor 14 operate with the power supplied from the auxiliary equipment power supply section.
[0033] As shown in FIG. 2, the lighting fixture 12 is long and formed to have approximately the same length as the fixture body. The lighting fixture 12 includes a chassis, a light source attached to the underside of the chassis, and a translucent cover attached to the chassis to cover the light source. The chassis is, for example, made of metal and is provided long. The light source is composed of a light emitting module having a long board and a plurality of light emitting elements mounted along the longitudinal direction of the board. The light emitting elements are, for example, LEDs or organic EL. The translucent cover has translucency and light diffusibility, and allows light from the light source to pass through. The light emitting module of the light source is connected to a power line from a light source power supply unit.
[0034] As shown in Fig. 2, the camera 13 and the sensor 14 are attached to the main body of the camera-equipped lighting device 11 as auxiliary devices. The camera 13 is configured as a camera unit including, for example, an imaging section and a control module. The camera 13 as a camera unit includes, for example, an imaging element such as a CCD (Charge Coupled Device) or a CMOS (Complementary Metal Oxide Semiconductor), and an imaging section including a lens that focuses an image on the imaging element. The control module of the camera 13 includes a storage section that stores captured video and images, a communication section that communicates with the outside and transmits video and images to the outside, and a camera control section that controls capture and communication.
[0035] The sensor 14 is composed of one or more sensors. The sensor 14 may be any sensor that detects the state of the lighting area where light from the lighting fixture 12 is irradiated. For example, the sensor 14 includes a brightness sensor that detects the brightness of the lighting area. The sensor 14 may also include a human presence sensor that detects a person in the lighting area.
[0036] Next, the configuration of a control system for camera-equipped lighting device 11 and lighting control device 20 in lighting control system 1 according to this embodiment will be described. FIG. 3 is a block diagram showing an example of the configuration of a control system of the camera-equipped lighting device 11 and the lighting control device 20 in the lighting control system 1 according to the embodiment. 3, the camera-equipped lighting device 11 includes a lighting fixture 12, a camera 13, a sensor 14, and a control unit 15. The camera-equipped lighting device 11 also includes a lighting power supply unit that is the power source for the lighting fixture 12, and an auxiliary equipment power supply unit that is the power source for the camera 13 and the sensor 14.
[0037] The control unit 15 includes a processor 15a, a memory 15b, and a communication interface 15c. In the control unit 15, the processor 15a includes, for example, a central processing unit (CPU), an application specific integrated circuit (ASIC), a microcomputer, a field programmable gate array (FPGA), and a digital signal processor (DSP).
[0038] Processor 15a executes programs stored in memory 15b to realize various processes as a control unit. For example, processor 15a performs lighting control of lighting fixture 12 based on lighting control setting information stored in memory 15b in response to information obtained from camera 13, sensor 14, etc. In the configuration example shown in Fig. 3, processor 15a is a first processor that performs lighting control of lighting fixture 12 in lighting system 10.
[0039] In addition, the processor 15a may perform a work content estimation process to estimate a person's work (action) in the image captured by the camera 13, as described below as a processing function of the lighting control device 20, and a recognition process to recognize the type and position of fixtures in the image captured by the camera 13.
[0040] In control unit 15, memory 15b is configured with a storage device such as a read only memory (ROM), a random access memory (RAM), or a non-volatile memory (NVM). For example, memory 15b stores lighting control setting information in a rewritable non-volatile memory such as NVM. Memory 15b may also store information indicating lighting control results of lighting fixtures 12, images captured by camera 13, information indicating detection results of sensor 14, and the like. Memory 15b may also store image analysis results for images captured by camera 13, and the like.
[0041] The communication interface 15c is configured by an interface for communicating with an external device. In the configuration example shown in Fig. 3, the communication interface 15c is an interface for communicating with the lighting control device 20 in the lighting system 10. However, when the control unit 15 is configured to transmit information to the analysis device 30, the communication interface 15c functions as a first communication interface. In the configuration example shown in FIG. 3, control unit 15 also includes interfaces (not shown) for connecting to devices such as lighting fixture 12, camera 13, and sensor 14.
[0042] Lighting fixture 12 includes a light source that emits light to illuminate a predetermined lighting area. The light source of lighting fixture 12 may be, for example, an LED. The LED serving as the light source of the lighting fixture emits light using power supplied from a lighting power supply unit. In lighting fixture 12, not only the turning on and off of the light source but also the dimming or color adjustment of the light emitted by the light source are controlled. In lighting fixture 12, the light emission state of the light source is controlled by processor 15a of control unit 15 in accordance with lighting control.
[0043] Camera 13 includes an imaging unit that captures images of a predetermined shooting range. Camera 13 is set so that the lighting area of lighting fixture 12 of camera-equipped lighting device 11 is included in the shooting range. Camera 13 may capture images (video) of the shooting range at a set frame rate. In the configuration example shown in FIG. 3, camera 13 supplies the captured images to control unit 15.
[0044] However, the camera 13 may be configured as a camera unit (module) equipped with an imaging section, a processor, a memory, an interface, and the like. In this case, the camera unit as the camera 13 may have various processing functions by not only having the imaging section capture an image of a predetermined shooting range, but also having a processor such as a CPU execute a program stored in the memory. For example, the camera unit as the camera 13 may have a processor functioning as a human detection means (human sensor) that detects the presence or absence of a person in the shooting range from the image captured by the imaging section. Also, the camera unit as the camera 13 may have a processor functioning as a brightness detection means that detects the illuminance of light in the shooting range from the image captured by the imaging section.
[0045] Sensor 14 detects information indicating the state of the area illuminated by lighting fixture 12. For example, sensor 14 includes an illuminance sensor (brightness detection means) that detects brightness. As a specific example, an illuminance sensor serving as sensor 14 detects the brightness of a surface onto which light is irradiated from lighting fixture 12. Sensor 14 may also include a human presence sensor (human detection means) that detects the presence or absence of a person. However, when camera 13 functions as human detection means or brightness detection means, sensor 14 may be omitted from the configuration of camera-equipped lighting device 11.
[0046] Next, the configuration of a control system of lighting control device 20 in lighting control system 1 according to an embodiment will be described. As shown in FIG. 3, the lighting control device 20 includes a processor 21, a system memory 22, a data memory 23, communication interfaces (I / F) 24, 25, a display unit 26, an operation unit 27, and the like. The processor 21 executes programs to realize various processes. The processor 21 is composed of, for example, a CPU. The system memory 22 is composed of memories such as ROM, RAM, and NVM. The processor 21 functions as a control unit that realizes various processing functions by working with the system memory 22. For example, the processor 21 executes programs using the system memory 22 to realize each processing function described below. In this case, the programs executed by the processor 21 are stored in non-volatile memory in the system memory 22 or in the data memory 23.
[0047] The data memory 23 is composed of a rewritable non-volatile memory such as a hard disk drive (HDD) and a solid state drive (SSD). For example, the data memory 23 stores application programs executed by the processor 21, setting information, and the like. The data memory 23 also stores setting information indicating a control method for lighting fixtures to be instructed to the camera-equipped lighting device 11. The data memory 23 also stores images captured by the camera 13 and detection information detected by the sensor 14 for each camera-equipped lighting device 11. The lighting control device 20 may store information in a storage device of an external device connected for communication with the lighting control device 20. In other words, some or all of the information stored in the data memory 23 may be stored in a storage device of an external device connected to the lighting control device 20.
[0048] The communication interface 24 is a communication unit for communicating with the camera-equipped lighting device 11, which is equipped with the lighting fixture 12, the camera 13, and the sensor 14. The communication interface 24 includes an interface corresponding to the communication interface equipped in the control unit 15 of the camera-equipped lighting device 11. The communication interface 25 is a communication unit for communicating with the analysis device 30. The communication interface 25 includes an interface corresponding to a communication interface provided in the analysis device 30. In the configuration example shown in FIG. 1, the communication interface 25 is a second communication interface for the lighting control device 20 as the lighting system 10 to communicate with the analysis device 30.
[0049] The display unit 26 is a display that displays information. The display unit 26 is composed of, for example, a liquid crystal display or an organic EL device. For example, the display unit 26 displays the proposed lighting control method, layout change, or part replacement based on the analysis result of the data accumulated by the analysis device 30. The display unit 26 may also display an image captured by the camera 13 of the camera-equipped lighting device 11. The operation unit 27 is composed of, for example, an input device for the operator to input operation instructions.
[0050] Next, the configuration of the analysis device 30 in the lighting control system 1 according to an embodiment will be described. FIG. 4 is a block diagram showing an example of the configuration of a control system of the analysis device 30 in the lighting control system 1 according to the embodiment. As shown in FIG. 4, the analysis device 30 includes a processor 31, a system memory 32, a data memory 33, and a communication interface (I / F) .
[0051] The processor 31 executes programs stored in the system memory 32 or the data memory 33 to realize each processing function described below. The processor is composed of, for example, a CPU. The system memory 32 is composed of memories such as ROM, RAM, and NVM. The processor 31 functions as a control unit that realizes various processing functions by cooperating with the system memory 32. For example, the processor 31 executes programs using the system memory 32 to realize each processing function described below. The programs executed by the processor 31 are stored in the non-volatile memory of the system memory 32 or the data memory 33.
[0052] The data memory 33 is configured with a rewritable non-volatile memory such as a hard disk drive (HDD) and a solid state drive (SSD). For example, the data memory 33 stores application programs executed by the processor 31 and setting information. The data memory 33 also stores various data related to the lighting space targeted for lighting control by the lighting system 10. Note that part or all of the information stored in the data memory 33 described in this embodiment may be stored in a storage device of an external device connected to the analysis device 30.
[0053] The communication interface 34 is an interface for external communication. The communication interface 34 is an interface for communicating with the lighting control device 20, and may include an interface corresponding to the communication interface 24 included in the lighting control device 20.
[0054] Next, information such as BIM data that the analysis device 30 stores in a storage device such as the data memory 33 will be described. In the above-described exemplary configuration of lighting control system 1, data memory 33 of analysis device 30 stores various data related to the lighting space targeted for lighting control by lighting system 10. According to the example shown in Fig. 4, data memory 33 of analysis device 30 stores building information 41, lighting operation information 42, work content information 43, fixture information 44, and reference information 45, etc.
[0055] The building information 41 includes information such as BIM data related to buildings (facilities such as offices and factories) as lighting spaces subject to lighting control by the lighting system 10. For example, the building information 41 includes BIM data indicating the positions and directions (orientations) of walls, windows, doors, and the like in a building that serves as a lighting space. The building information 41 also includes BIM data indicating the installation positions and installation directions of the lighting fixtures 12, cameras 13, sensors 14, and the like in the building.
[0056] The lighting operation information 42, the work content information 43, and the fixture information 44 are information acquired from the lighting control device 20 of the lighting system 10. The lighting operation information 42 includes information indicating the content of lighting control (on / off, dimming, color adjustment, etc.) performed by each camera-equipped lighting device 11 on the lighting fixtures 12 during operation of the lighting system 10. The lighting operation information 42 may also include information indicating the state of the lighting area of the lighting fixtures 12 detected by the sensor 14 (brightness, presence or absence of people, etc.).
[0057] The work content information 43 and the fixture information 44 are information obtained by the lighting control device 20 (or the control unit 15) performing image analysis (image recognition) on the images captured by the camera 13 of each camera-equipped lighting device 11. The work content information 43 is information indicating the number of people present in the lighting area (shooting range) estimated from the image captured by the camera 13 and the work being performed by the people present in the lighting area (e.g., paper work, PC work, meetings, breaks, etc.).
[0058] The fixture information 44 is information indicating the state (e.g., type, position, etc.) of the fixtures present in the lighting area (shooting range) recognized from the image captured by the camera 13. Furthermore, the fixture information 44 stored in the data memory 33 may be updated when the type and position of the fixtures indicated by the fixture information as the image recognition result for the image captured by the camera 13 obtained from the lighting system 10 changes.
[0059] The reference information 45 is information indicating reference or recommended setting values for creating proposal contents such as a lighting control method, layout, and part replacement proposed according to the actual operating situation in the lighting space. The reference information 45 includes information indicating recommended (reference) values for lighting control (brightness, light color, etc.) recommended for various types of work. For example, the reference information 45 includes recommended lighting control values for paper work, PC work, meetings, and breaks as work contents. As a specific example, in the reference information 45, the recommended lighting control value for paper work is set to have a higher illuminance than the recommended lighting control values for PC work and meetings, and the recommended lighting control value for breaks is set to a color temperature that provides a relaxing effect.
[0060] Furthermore, the reference information 45 includes recommended (reference) values for the layout indicating the type and position of fixtures recommended depending on the work content. For example, the reference information 45 includes information indicating a recommended layout (type, number, arrangement, etc. of fixtures) corresponding to the number of people present in the lighting area and the type of work. As a specific example, the reference information 45 may set recommended values for proposing the type, number, arrangement, etc. of chairs and tables depending on the number of people holding a meeting in a specific area, or set recommended values for proposing the type, number, arrangement, etc. of chairs and sofas depending on the number of people taking a break in a specific area.
[0061] Furthermore, the reference information 45 includes information indicating the replacement timing and the notification timing for replacement of each part in the lighting system 10. For example, the reference information 45 includes information indicating the replacement timing of a part that serves as a light source in the lighting fixture 12 and the notification timing for notifying the replacement. The analysis device 30 refers to the standard information 45 and analyzes the building information 41, lighting operation information 42, work content information 43 and fixture information 44 stored in the data memory 33 to propose lighting control, layout, or part replacement, etc., according to actual operations.
[0062] Next, the operation of the lighting control system 1 according to the embodiment will be described. First, an example of the operation of the camera-equipped lighting device 11 of the lighting system 10 in the lighting control system 1 according to the embodiment will be described. In the lighting system 10, the processor 15a of the control unit 15 of each camera-equipped lighting device 11 performs lighting control of the lighting fixtures 12 in accordance with the lighting control setting information. The lighting control setting information includes setting values indicating the state (on / off, dimming, color adjustment) of the lighting fixture 12 in accordance with the situation of the lighting area (brightness and the presence or absence of people). In other words, the processor 15a of the control unit 15 of the camera-equipped lighting device 11 detects the state of the lighting area from the image captured by the camera 13 or the detection signal of the sensor 14, and performs lighting control of the lighting fixtures 12 in accordance with the lighting control setting information in accordance with the detected state of the lighting area.
[0063] For example, processor 15a of control unit 15 of each camera-equipped lighting device 11 controls lighting fixtures 12 in accordance with the brightness detected by sensor 14 as brightness detection means or the brightness detected from an image captured by camera 13. Also, processor 15a of control unit 15 of each camera-equipped lighting device 11 controls lighting fixtures 12 in accordance with the result of human detection using sensor 14 or camera 13 as human detection means.
[0064] In addition, in the lighting system 10, the control unit 15 of each camera-equipped lighting device 11 communicates with the lighting control device 20 and supplies various information to the lighting control device 20. For example, the processor 15a of the control unit 15 transmits information (lighting operation information) indicating the control result of the lighting fixture 12 to the lighting control device 20 at a predetermined timing (e.g., a predetermined cycle). The processor 15a of the control unit 15 also transmits images captured by the camera 13 (e.g., moving images captured at a predetermined frame rate) to the lighting control device 20 at a predetermined timing. Furthermore, the processor 15a of the control unit 15 may also include information indicating the detection result by the sensor 14 in the lighting operation information and supply it to the lighting control device 20.
[0065] Furthermore, in the lighting system 10, the control unit 15 of each camera-equipped lighting device 11 communicates with the lighting control device 20 and updates the lighting control setting information in accordance with the lighting control method specified by the lighting control device 20. For example, when the processor 15a of the control unit 15 of each camera-equipped lighting device 11 receives the lighting control method for the lighting fixtures 12 from the lighting control device 20, it updates the lighting control setting information stored in the memory 15b to the lighting control method specified by the lighting control device 20.
[0066] Next, the operation of the lighting control device 20 of the lighting system 10 in the lighting control system 1 according to the embodiment will be described. FIG. 5 is a flowchart for explaining an example of the operation of the lighting control device 20 of the lighting system 10 in the lighting control system 1 according to the embodiment. In the lighting system 10, the processor 21 of the lighting control device 20 acquires lighting operation information indicating the lighting control results for the lighting fixtures 12 from each camera-equipped lighting device 11 (step ST11). For example, the processor 21 acquires lighting operation information including the identification information of each camera-equipped lighting device 11 from each camera-equipped lighting device 11. Here, the lighting operation information includes the identification information of the camera-equipped lighting device 11, the control results of the lighting fixtures 12, the detection results of the sensor 14, and information such as the time.
[0067] Processor 21 of lighting control device 20 supplies the lighting operation information acquired from each camera-equipped lighting device 11 to analysis device 30 (step ST12). For example, processor 21 of lighting control device 20 supplies the lighting operation information acquired from each camera-equipped lighting device 11 to analysis device 30 at a predetermined timing.
[0068] The processor 21 of the lighting control device 20 also acquires images captured by the camera 13 from each of the camera-equipped lighting devices 11 (step ST13). The processor 21 acquires from each of the camera-equipped lighting devices 11 the images captured by the camera 13, to which information such as the identification information of each of the camera-equipped lighting devices 11 and the time of capture has been added.
[0069] The processor 21 of the lighting control device 20 executes image analysis processing on the images captured by the camera 13 acquired from each camera-equipped lighting device 11. In this embodiment, the processor 21 of the lighting control device 20 executes a task content estimation process and a fixture recognition process as the image analysis process on the images captured by the camera 13. However, the image analysis process on the images captured by the camera 13 may be executed by the control unit 15 of each camera-equipped lighting device 11. In this case, the lighting control device 20 may acquire the results of the image analysis processing from each camera-equipped lighting device 11 and proceed to step ST16.
[0070] As a task content estimation process, the processor 21 of the lighting control device 20 extracts images in which people are present from the images captured by the cameras 13 acquired from each camera-equipped lighting device 11, and estimates (recognizes) the number of people present in the captured images (lighting area) and the tasks (behavior) performed by the people (step ST14). The processor 21 may detect the presence or absence of people in the captured images from the captured images, or may detect it based on the detection results of a human presence sensor as the sensor 14. For example, the processor 21 acquires successive captured images in which people are present from the images captured by each camera 13 as a moving image, and estimates the task content as the behavior of the people based on changes in the positions and postures of the people in the moving image.
[0071] As a specific example, when the captured image detects that a person is working on paper, the processor 21 presumes that a person is working on paper in the captured range (illumination area). When the captured image detects that a person is operating an input device such as a keyboard facing a display of a personal computer (PC), the processor 21 presumes that a person is working on a PC in the captured range. When the captured image detects that multiple people are talking face to face, the processor 21 presumes that people are having a meeting in the captured range. When the captured image detects that a person is taking a break, the processor 21 presumes that a person is taking a break in the captured range.
[0072] Furthermore, as a fixture recognition process, the processor 21 of the lighting control device 20 recognizes (estimates) the position and type of fixtures present in the shooting range (lighting area) of each camera 13 from the images captured by each camera 13 (step ST15). For example, the processor 21 recognizes the type and position of the fixture by pattern matching with the images captured by the camera 13, and treats the recognition result as fixture information. The processor 21 may also detect fixtures whose position or type has changed by comparing with images captured in the past by the same camera 13, and treat the recognition result of the type and position of the fixture whose state has changed as fixture information.
[0073] After executing image analysis processing including a work content estimation process and a fixture recognition process, processor 21 of lighting control device 20 transmits the result of the image analysis process to analysis device 30 (step ST16). Processor 21 acquires the result of the work content estimation process and the result of the fixture recognition process for each camera-equipped lighting device 11 in lighting system 10. As a result, processor 21 transmits to analysis device 30 the work content and fixture information within the shooting range of camera 13 corresponding to the lighting area of lighting fixture 12 of each camera-equipped lighting device 11.
[0074] Processor 21 of lighting control device 20 repeatedly performs the processes of steps ST11-ST16 above, and also receives a proposal of a lighting control method or layout from analysis device 30 (step ST17).
[0075] When the processor 21 of the lighting control device 20 receives a proposal from the analysis device 30 (step ST17, YES), it displays the proposal content proposed by the analysis device 30 on the display unit 26 (step ST18). The proposal content from the analysis device 30 is a proposal for a lighting control method, a layout change, or a part replacement. The proposal content may be notified to the operator by email or the like. In this case, the proposal content may be displayed on the display unit 26 when the operator opens the email.
[0076] Here, in the case where the proposed content is a lighting control method, if the operator accepts the proposed lighting control method, he or she will instruct the application of the proposed content through the operation unit 27. When processor 21 of lighting control device 20 is instructed by analysis device 30 to apply the proposed lighting control method (step ST19, YES), it performs a process of updating lighting control setting information for target lighting fixtures 12 according to the proposed lighting control method (step ST20). For example, processor 21 identifies camera-equipped lighting device 11 equipped with lighting fixture 12 to which the proposed lighting control method is to be applied, and instructs identified camera-equipped lighting device 11 to update lighting control setting information to setting information according to the lighting control method. In response, control unit 15 of camera-equipped lighting device 11 updates the lighting control setting information for lighting fixture 12 to lighting control setting information according to the proposed lighting control method.
[0077] As a specific example, when processor 21 is instructed to apply a lighting control method that reduces illuminance in a specific area, processor 21 updates the lighting control setting information of camera-equipped lighting device 11 equipped with lighting fixtures 12 that illuminate the specific area to a setting that reduces illuminance. Also, when processor 21 is instructed to apply a lighting control method that reduces color temperature in a specific area, processor 21 updates the lighting control setting information of camera-equipped lighting device 11 equipped with lighting fixtures that illuminate the specific area to a setting that reduces color temperature. Also, when processor 21 is instructed to apply a lighting control method that increases illuminance in a specific area during a specified time period, processor 21 updates the lighting control setting information of camera-equipped lighting device 11 equipped with lighting fixtures 12 that illuminate the specific area to a setting that reduces illuminance during the specified time period.
[0078] The lighting control device 20 may execute the process of updating the lighting control setting information to a lighting control method proposed by the analysis device 30 without an instruction from an operator. In other words, when processor 21 of lighting control device 20 receives a proposal of a lighting control method from analysis device 30, the processes of steps ST18 and ST20 may be omitted, and processor 21 of lighting control device 20 may instruct camera-equipped lighting device 11 including lighting fixture 12 to which the lighting control method is applied to update the lighting control setting information to setting information corresponding to the lighting control method. This allows control unit 15 of camera-equipped lighting device 11 to update the lighting control setting information to a lighting control method proposed by the analysis device 30 without an operation by an operator.
[0079] 5, the processes of steps ST11-16 may be executed by the control unit 15 of each camera-equipped lighting device 11 in the lighting system 10. In this case, the control unit 15 of each camera-equipped lighting device 11 may supply various information (lighting operation information, work content information, fixture information) to the analysis device 30.
[0080] 5, the processing of steps ST17-20 may be performed by the analysis device 30 using a display device and an operation device connected to the analysis device 30. In this case, the processor 31 of the analysis device 30 may display the proposed content on a display device that is visually recognized by the operator, or update the lighting control setting information of the camera-equipped lighting device 11 according to the proposed lighting control method.
[0081] Next, the operation of the analysis device 30 in the lighting control system 1 according to this embodiment will be described. FIG. 6 is a flowchart illustrating an example of the operation of the analysis device 30 in the lighting control system 1 according to the embodiment. In the lighting control system 1, the analysis device 30 accumulates various information acquired from the lighting control device 20, and analyzes the accumulated information to recommend a lighting control method, recommend a layout change, or whether or not a part replacement notice is required. If there is anything to be suggested based on the analysis process of the accumulated information, the analysis device 30 outputs the suggested content.
[0082] That is, processor 31 of analysis device 30 acquires lighting operation information including lighting control results for lighting fixtures 12 of each camera-equipped lighting device 11 from lighting control device 20 (step ST31). Processor 31 of analysis device 30 accumulates the lighting operation information of each camera-equipped lighting device 11 acquired from lighting control device 20 in data memory 33 (step ST32).
[0083] Furthermore, the processor 31 of the analysis device 30 acquires image analysis results including estimation results of work content and fixture recognition results in the shooting range (lighting area) of the camera 13 for each camera-equipped lighting device 11 from the lighting control device 20 (step ST33). The processor 31 of the analysis device 30 accumulates the image analysis results for each camera-equipped lighting device 11 acquired from the lighting control device 20 in the data memory 33 (step ST34).
[0084] That is, the processor 31 accumulates information indicating the estimation result of the work content for each camera-equipped lighting device 11 in the data memory 33 as work content information 43. The processor 31 also accumulates the recognition result of the fixtures for each camera-equipped lighting device 11 in the data memory 33 as fixture information 44. However, the processor 31 may determine whether or not there has been a change in the type or position of the fixtures based on the recognition result of the fixtures for each camera-equipped lighting device 11, and update the fixture information 44 in the data memory 33 if there has been a change in the fixtures.
[0085] The processor 31 of the analysis device 30 repeatedly performs the processes of steps ST31-34 and determines whether to perform an analysis of data for proposing a lighting control method or the like depending on whether a predetermined analysis execution condition is met (step ST35). As the analysis execution condition, for example, a predetermined period such as one day or one week may be set, or a threshold value for the amount of data accumulated in the data memory 33 may be set. For example, if the analysis is set to be performed every predetermined period, the processor 31 determines whether to perform the analysis depending on whether the predetermined period has arrived. The processor 31 accumulates the lighting operation information, work content information, and fixture information corresponding to each camera-equipped lighting device in the data memory 33 until the analysis execution condition is met.
[0086] When the processor 31 of the analysis device 30 determines that the analysis conditions are met and that the analysis should be performed (step ST35, YES), it executes an analysis process of the information stored in the data memory 33 (step ST36). As the analysis process, the processor 31 analyzes the lighting operation information, work content information, and fixture information while referring to the reference information 45 indicating recommended settings, etc., to propose a lighting control method, layout change, part replacement, etc.
[0087] Processor 31 of analysis device 30 estimates how people (workers) are using (actual operation) each lighting area of lighting fixtures 12 (or a specific area consisting of multiple lighting areas) from lighting operation information, work content information, fixture information, etc. Processor 31 determines the lighting control method of lighting fixtures 12 and the layout of fixtures according to the estimated actual operation while referring to reference information 45.
[0088] Below, specific examples of proposal contents created by the processor 31 of the analysis device 30 through analysis processing will be illustrated. For example, the processor 31 of the analysis device 30 proposes layout changes or changes in use of a specific area depending on the utilization rate of people (e.g., workers) in the specific area. As a specific example, the processor 31 proposes a layout change such as removing some or all of the chairs and tables from an area that is rarely used (low utilization rate). The processor 31 may also propose a layout change for an area with a low utilization rate to encourage use of the area for work content different from the work content being performed in the area. The processor 31 also proposes a layout change such as increasing the number of chairs and tables in an area that is always highly utilized.
[0089] Furthermore, the processor 31 of the analysis device 30 proposes (re-proposes) a lighting control method according to how people (workers) use a specific area. That is, the processor 31 may propose a lighting control method that recommends changes in illuminance, light color, etc., in accordance with the reference information 45 indicating the recommended illuminance, color temperature, etc., set for each type of work (work on a PC, work on paper, meeting, break, etc.). As a specific example, the processor 31 refers to the reference information and suggests lowering the illuminance below the current illuminance indicated by the lighting operation information for an area where more people are working on a PC than previously expected. The processor 31 also refers to the reference information and suggests lowering the color temperature for an area where more people are taking a break than previously expected.
[0090] Furthermore, the processor 31 of the analysis device 30 detects changes in illuminance due to the influence of external light caused by the time of day, etc., and proposes (re-proposes) a lighting control method according to the time of day and weather. That is, the processor 31 may detect that the illuminance changes with the time of day due to the influence of light entering through windows, etc., and propose a lighting control method that brings the illuminance of the area to the illuminance indicated by the reference information according to the change in illuminance with time. As a specific example, the processor 31 identifies an area where the afternoon sun shines from the position and direction of windows indicated by the building information 41, and proposes lowering the illuminance during the time period when the afternoon sun shines.
[0091] Furthermore, the processor 31 of the analysis device 30 may detect a change in illuminance due to the influence of external light caused by weather, etc., and propose (re-propose) a lighting control method for changing the illuminance according to the weather. In this case, the analysis device 30 may be connected to a server that provides weather information so that the weather information can be acquired. As a specific example, the processor 31 may propose to reduce the illuminance in an area having a window through which external light enters if the weather is sunny, and to reduce the illuminance if the weather is cloudy or rainy.
[0092] Furthermore, the processor 31 of the analysis device 30 associates lighting control by human operation in a specific area with the work content, estimates the preference of lighting conditions (illuminance, light color, etc.) according to the work content, and proposes a lighting control method that achieves the estimated preference. In this case, the lighting operation information acquired from each camera-equipped lighting device 11 includes a record of lighting control in response to instructions from a mobile terminal such as a remote control or smartphone. As a specific example, if there is a tendency to control the lighting to be lowered when multiple people are having a meeting in a specific area, the processor 31 proposes lowering the illuminance of the lighting device 12 when the camera-equipped lighting device 11 in the specific area detects multiple people.
[0093] Furthermore, the processor 31 of the analysis device 30 may be configured to suggest replacement of a lighting fixture 12 whose usage time (lighting time) is approaching a predetermined replacement time. In this case, the replacement time for each lighting fixture 12 and the replacement proposal period during which the replacement is proposed may be set in the reference information, and the processor 31 may be configured to suggest replacement of a lighting fixture 12 whose usage time (lighting time) calculated from the lighting operation information has reached the replacement proposal time.
[0094] When the analysis process using the accumulated information is completed, the processor 31 of the analysis device 30 judges whether or not there is a suggestion as a result of the analysis process (step ST37). If there is no suggestion as a result of the analysis process (step ST37, NO), the processor 31 returns to the above step ST31 and repeats the above-mentioned process.
[0095] Furthermore, if there is a proposal as a result of the analysis process (step ST37, YES), the processor 31 of the analysis device 30 outputs the proposal content obtained by the analysis process (step ST38). The processor 31 may provide the proposal content obtained by the analysis process to a system administrator or the like. Here, it is assumed that the lighting control device 20 displays the proposal content on the display unit 26 as described above.
[0096] In this case, the processor 31 of the analysis device 30 outputs the proposal content obtained by the analysis process to the lighting control device 20. The proposal content output to the lighting control device 20 includes display data for display on the display unit 26 of the lighting control device 20. The processor 31 of the analysis device 30 may also cause the display unit 26 of the lighting control device 20 to display that there is a proposal based on the accumulated information, and cause the display unit 26 to display display data indicating the proposal content in response to a display instruction from the operator.
[0097] The display data for showing the proposed contents may be display data that displays the proposed contents, such as a lighting control method, a layout change, or replacement of consumables, in 3D using BIM data of the building that is the space to be illuminated. In this case, the processor 31 creates display data showing the proposed contents in a 3D image using the BIM data of the building. This enables the analysis device 30 to display the display data showing the proposed contents as an analysis result of the accumulated information on the display unit 26 as an image that is easy for the operator to intuitively recognize.
[0098] In the above-described process, the analysis device 30 creates proposals such as lighting control methods, layouts, and part replacements by performing analysis processing on the accumulated information. However, the present invention is not limited to this, and the analysis device 30 may create and output a report showing information obtained by analyzing the accumulated information.
[0099] For example, the processor 31 of the analysis device 30 may calculate the energy consumption by each lighting fixture in the lighting system 10 based on the lighting operation information stored in the data memory 33, and create and output a report showing the calculated energy consumption. Specifically, the processor 31 can calculate the energy consumption for a predetermined period of time (e.g., one day, one week, etc.) by acquiring the specifications of the lighting fixtures 12 indicated by the BIM data of the lighting fixtures 12 and the lighting control results for the actual lighting fixtures 12 identified from the lighting operation information.
[0100] This allows processor 31 of analysis device 30 to calculate the energy consumption by each lighting fixture 12 in the entire lighting system 10 by analyzing the information stored in data memory 33. In addition, as an example, processor 31 of analysis device 30 can also create a report showing the energy reduction effect of the proposed lighting control method by calculating the energy consumption before and after updating the lighting control setting information according to the proposed lighting control method described above.
[0101] Furthermore, the processor 31 of the analysis device 30 may create and output a report showing what types of work are frequently performed in each area of the building (lighting space) based on the work content information stored in the data memory 33. Specifically, the processor 31 identifies the number of people and the work content for each lighting area from the work content information, and can create a report showing the work status in each area by aggregating them.
[0102] As described above, in the lighting control system according to the embodiment, the analysis device accumulates lighting operation information indicating the control results of the lighting fixtures, task content information indicating human behavior in the lighting area of the lighting fixtures from images captured by the camera, and fixture information indicating the position and type of fixtures present in the lighting area. The analysis device identifies the actual operation status of the lighting area by analyzing the accumulated information, and proposes lighting control for the lighting fixtures and fixture layouts that match the actual operation in the lighting area.
[0103] As a result, with the lighting control system according to the embodiment, it is possible to propose lighting control and fixture layout that are suited to actual operations, and to provide a comfortable working environment with lighting that suits the actual operating conditions for workers working in lighting areas of lighting fixtures in offices, etc.
[0104] Although some embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention.
