FIG. 4 is a diagram illustrating a detection range 60 of the image sensor 5. FIG. 4 is an example of an image obtained by capturing an image from the ceiling to the floor with a camera mounted on the image sensor 5. The image sensor 5 is arranged, for example, in the center of the detection range 60. The detection range 60 of the image sensor 5 of the present embodiment is a square area of 7.2 m square on the floor surface. The area and shape of the detection range 60 are not limited to this. The detection range 60 varies depending on the type, performance, and detection accuracy of the camera used for the image sensor 5.

The image sensor 5 divides the space having the detection range 60 into a plurality of detection blocks 61, and detects the presence or absence of a person for each of the plurality of detection blocks 61. The image sensor 5 acquires an image for each detection block 61, compares the acquired image with a base image stored in advance, and detects the presence or absence of a person.

One detection block 61 is a 0.9 m square. The detection blocks 61 are arranged in eight rows on one side of the detection range 60. The detection range 60 has 64 detection blocks 61. The area and shape of the detection block 61 and the arrangement of the plurality of detection blocks 61 are not limited to this. Further, the number of detection blocks 61 included in one detection range 60 may be plural.

The imaging range of the camera mounted on the image sensor 5 is wide-angle. The detection may be masked at the outer peripheral portion of the imaging range of the image sensor 5. That is, the camera may be used by arbitrarily narrowing the detection range. Further, a higher performance image sensor 5 may be used. For example, the detection range 60 of 7.2 m square may be divided into 256 blocks having 16 rows on each side for detection.

FIG. 4 shows an example in which a plurality of chairs 10, a round table 11, a quadrangular table 12, and a counter table 13 are laid out in a space having a detection range of 60. The plurality of chairs 10 provided around the round table 11 include those that fit in one detection block 61 and those that straddle two detection blocks 61. Further, each of the plurality of chairs 10 provided around the square table 12 and the counter table 13 fits in one detection block 61.

As an initial setting of the control system 100, the management device 8 allocates and sets each position of the plurality of chairs 10 and the corresponding detection block 61. By detecting a person in the detection block 61, the management device 8 determines that the user is sitting in the seat arranged in the detection block 61. In addition, the management device 8 determines that the seats arranged in the detection block 61 that does not detect a person are vacant seats.

The image sensor 5 is equipped with an algorithm for detecting the intrusion, movement, stay, and passage of an object. When the image sensor 5 detects the intrusion, movement, or passage of a person, it does not immediately determine that the person has been seated. When a person stays in the detection block 61 for a predetermined time or longer, the image sensor 5 detects the presence of the person in the detection block 61. That is, when the image sensor 5 detects that the moving object has stopped and stayed for a predetermined time, it determines that the moving object is seated.

When the image sensor 5 determines that a person is seated on the detection block 61, the image sensor 5 transmits the information for identifying the detection block 61 and the stay state to the controller 1. Further, when it is detected that the user in the seat has left, the image sensor 5 transmits the information for identifying the detection block 61 to the controller 1 and the absence state.

FIG. 5 is a diagram illustrating a seat identification number. An identification number is assigned to each of the multiple seats. As an example, in FIG. 5, identification numbers 1 to 19 are assigned to each of a plurality of seats. The plurality of seats with the identification numbers are displayed together with the vacant seat information in the layout diagram displayed on the display device 9. The identification number is required when the management device 8 maps the seat position to the layout drawing.

FIG. 6 is a diagram for explaining the numbers assigned to the detection block 61. Serial numbers 1 to 64 are assigned to the plurality of detection blocks for management. The controller 1 or the management device 8 has a function of arbitrarily setting the number of detection blocks 61. As a result, even if the number of detection blocks 61 changes due to the performance of the camera or the like, the serial number can be automatically changed.

FIG. 7 is a diagram for explaining the correspondence between the seat identification number and the detection block 61. The seat number in FIG. 7 indicates a seat identification number. The management device 8 creates and stores a table that associates the identification numbers of the plurality of seats with the plurality of detection blocks 61. Thereby, the management device 8 can associate each seat with which detection block 61 is installed. Not limited to this, the management device 8 may store the correspondence between the plurality of seats and the plurality of detection blocks 61.

Information on the presence or absence of a person in each detection block 61 detected by the image sensor 5 is transmitted to the management device 8 via the controller 1 and the gateway device 7. The management device 8 extracts the seat identification number corresponding to the detection block 61 from the serial number and the table of the detection block 61 included in the received data. As a result, the management device 8 determines whether the seats are present or vacant for each of the plurality of seats.

The display device 9 includes a screen for displaying a layout diagram or a diagram in which seat positions are mapped. The management device 8 displays information on the presence or absence of seats at the positions of the respective seats on the screen of the display device 9. That is, the display device 9 displays information about vacant seats of a plurality of seats based on the determination result of the management device 8.

Further, the management device 8 can calculate the number of vacant seats and display it on the screen of the display device 9 as information about the vacant seats.

Further, among the plurality of seats shown in FIG. 5, for example, the first seat having the identification number 10 is provided across the plurality of adjacent first detection blocks having the serial numbers 15 and 16. In this case, the management device 8 determines that the first seat is present if there is a person in one or more of the plurality of first detection blocks. Further, the management device 8 determines that the first seat is vacant if no person is present in all of the plurality of first detection blocks.

FIG. 8 is a diagram illustrating the arrangement of the lighting fixture 2. In the present embodiment, 16 lighting fixtures 2 are installed on the ceiling within the detection range 60. The number of lighting fixtures 2 provided in the detection range 60 may be one or more. Each luminaire 2 has a unique address. Therefore, the controller 1 can individually perform ON / OFF control, dimming control, and color temperature control for each address. Further, the plurality of lighting fixtures 2 may be grouped. In this case, a plurality of lighting fixtures 2 can be controlled at the same time for each group.

FIG. 9 is a diagram for explaining the correspondence between the seat identification number and the identification information of the lighting fixture 2. In addition to the allocation of the detection block 61 to the seat identification number shown in FIG. 7, the management device 8 allocates the identification information of the lighting fixture 2 to the seat identification number. The identification information of the luminaire 2 is an individual number or a group number of the luminaire 2. The management device 8 stores a table that associates the identification numbers of the plurality of seats with the identification information of the plurality of lighting fixtures 2. Not limited to this, the management device 8 may memorize the correspondence between the plurality of lighting fixtures 2 and the plurality of seats.

The management device 8 refers to the correspondence between the plurality of lighting fixtures 2 and the plurality of seats, and controls the lighting state of the plurality of lighting fixtures 2 based on the determination results of the presence and absence of the plurality of seats. That is, the management device 8 controls dimming of the lighting fixture 2 corresponding to the detection block 61 included in the data received from the image sensor 5.

For example, the management device 8 increases the dimming rate of the corresponding luminaire 2 when present, and dims or turns off the corresponding luminaire 2 when the person is absent. That is, the management device 8 makes the dimming rate of the lighting fixture 2 that illuminates the seat determined to be present among the plurality of seats higher than the dimming rate of the lighting fixture 2 that illuminates the seat determined to be vacant. As a result, power consumption can be reduced in a space such as a store where the control system 100 is provided. In addition, the effect of lighting the space can be improved.

The table shown in FIG. 9 may be stored in either the management device 8 or the controller 1. Further, the allocation of the identification information of the lighting fixture 2 to the seat identification number may be performed by either the management device 8 or the setting device 6.

Further, the controller 1 may automatically feed back the illuminance value detected by the illuminance sensor 3 to the control of the luminaire 2. That is, the controller 1 may control the lighting state of the luminaire 2 according to the illuminance value. Further, the controller 1 may control the lighting state of the lighting fixture 2 according to the operation of the wall switch. Further, the controller 1 may perform fade-in control or fade-out control in which the dimming rate of the luminaire 2 is continuously and stepwise changed. Further, the controller 1 may perform scheduled operation control for changing the lighting state or the set value of the lighting fixture 2 with the passage of time. Further, the controller 1 can operate by combining these controls.

In the control system 100 of the present embodiment, the actual detection area is photographed by the image sensor 5 to detect the presence or absence of a person in each detection block 61. Further, the presence or absence of each seat is determined by using the correspondence between the plurality of seats and the plurality of detection blocks 61. Therefore, it is possible to easily correspond the positions of a plurality of seats with the information on the presence and absence of seats. Further, even when the layout is changed or the number of seats is changed, the control system 100 can be easily applied to the new environment by updating the table corresponding to the identification numbers of the plurality of seats and the plurality of detection blocks 61. it can. Therefore, the control system 100 can be updated at low cost.

According to the control system 100 of the present embodiment, it is possible to detect the usage status of seats in a store or the like and display the number of vacant seats or the vacant seat position on the screen of the display device 9 installed in the store or the like. Therefore, the user can know the vacant seat information in the store in advance.

Further, in the present embodiment, it is not necessary to install a chair equipped with a seating sensor in order to obtain information on the presence or absence of seats. Therefore, the cost incurred when adding a seat can be suppressed. In addition, various types of chairs can be introduced.

As a modification of the present embodiment, the functions of the management device 8 and the controller 1 may be realized by one device. Further, the functions of the management device 8 and the display device 9 may be realized by one device. Further, the space may be divided into a plurality of detection ranges 60. In this case, the image sensor 5 is arranged in each detection range 60.

Further, the image sensor 5 may have a function of comparing the previous image data with the image data captured this time. As a result, the image sensor 5 may detect changes in the layout of a plurality of seats. Further, the management device 8 may automatically correct the correspondence between the plurality of seats and the plurality of detection blocks 61 according to the change in the layout.

Further, the image sensor 5 divides the space into a plurality of detection blocks 61, and detects the presence or absence of a person in each of the plurality of detection blocks 61 provided with at least a plurality of seats. Just do it. For example, the image sensor 5 may automatically set the detection block 61 that detects the layout and detects the presence or absence of a person among the plurality of detection blocks 61 according to the layout.

These modifications can be appropriately applied to the control system according to the following embodiments. Since the control system according to the following embodiment has much in common with the first embodiment, the differences from the first embodiment will be mainly described.

Embodiment 2.
FIG. 10 is a diagram illustrating an object detection position 14. The image sensor 5 of the present embodiment detects the presence or absence of an object in addition to the presence or absence of a person. The image sensor 5 detects that an object is newly placed on the base image by a detection algorithm. The image sensor 5 acquires an image for each of the plurality of detection blocks 61, compares the acquired image with the base image stored in advance, and detects the presence or absence of an object added to the state indicated by the base image.

The image sensor 5 updates the base image at a predetermined time. The predetermined time is determined according to the timing of changing the layout or the timing of newly placing decorations, equipment, etc. in the space. The base image may be updated periodically by the image sensor 5, or may be updated by the user after the layout is changed. For example, the base image may be updated every morning at a fixed time before the store opens. As a result, the image sensor 5 can detect an object that appears after the seat user has moved.

FIG. 10 shows the correspondence between the object detection position 14 and the seat. The object detection position 14 indicates a position where an object is detected. When an object is detected at the position of the number surrounded by a square, the seat with the same number is determined to be present.

FIG. 11 is a diagram for explaining the correspondence between the seat identification number and the object detection position 14 according to the second embodiment. The management device 8 stores a table that associates the identification numbers of the plurality of seats with the object detection position 14. The table shows the detection block 61 in which the object is detected as the object detection position 14. The table contains information indicating, for each of the plurality of seats, which detection block 61 is determined to be present when an object is present. Not limited to this, the management device 8 may memorize the correspondence between the object detection position 14 and the plurality of seats.

After visiting the store, the user may secure a seat and then move to another place to purchase food and drink. In this case, even if the user is not seated, the seat cannot be said to be vacant.

On the other hand, in the present embodiment, not only the seated user but also the luggage or the like temporarily placed by the user to secure a seat can be detected. Therefore, the management device 8 can determine that the user is present by using the information from the image sensor 5 even when the user is not actually seated.

In FIG. 10, the object detection position 14 is on the desk. Not limited to this, the object detection position may be on the chair 10. For each seat, the management device 8 determines that the seat is present when an object is present on or on the desk corresponding to the seat. The image sensor 5 detects the presence or absence of a person or an object at the position of the chair 10, and detects only the presence or absence of an object at the position of the desk.

Further, a plurality of object detection positions 14 may be set for one seat number. For example, in the present embodiment, a plurality of second detection blocks having serial numbers 31 and 32 are set as object detection positions 14 for the second seat having the identification number 11. The management device 8 determines that the second seat is present when an object is present in any of the plurality of second detection blocks.

Further, one object detection position 14 may be set across a plurality of seat numbers. That is, the management device 8 may determine that a plurality of third seats among the plurality of seats are present when an object is present in the third detection block among the plurality of detection blocks 61.

Further, the image sensor 5 may detect the layout and automatically set the detection block 61 that detects the object as the object detection position 14 according to the layout. Further, when the image sensor 5 compares the previous image data with the image data captured this time and detects a change in the layout, the detection block 61 for detecting an object may be automatically changed.
