Details of the control system 1 according to the present embodiment will be described below.

The control system 1 includes a plurality of (20 in this embodiment) operating devices 2 and a control device 3 .

The twenty operating devices 2 are arranged one by one on the desks of the twenty seats 5, respectively. That is, the plurality of operating devices 2 correspond to the plurality of seats 5 on a one-to-one basis. When distinguishing the 20 operating devices 2, they are referred to as a first operating device SW1, a second operating device SW2, a third operating device SW3, . . . , a twentieth operating device SW20.

The operation device 2 is a switch device that notifies the surroundings of the usage status of the seat 5 on which the device (operation device 2) is installed, and outputs the usage status to the control device 3 by a radio signal.

The operation device 2 includes an operation section 21 , a display section 22 , a power generation section 23 and an output section 24 .

The operation unit 21 is configured to move according to a user's input operation. In the present embodiment, the operation unit 21 is configured to allow a reciprocating slide operation along one direction as an input operation. The operation unit 21 has, for example, a knob on which a user's finger is hooked, and can be reciprocated between a first position, which is one end of a movement range along one direction, and a second position, which is the other end. configured as possible. The operation unit 21 performs, as input operations, a first operation of moving from the first position to the second position and a second operation of moving from the second position to the first position.

The display unit 22 is configured to display the usage status of the corresponding seat 5 . The display unit 22 has two notations, for example, the notation "present" indicating that the seat 5 is in use and the notation "absent" indicating that the seat 5 is vacant. . According to the movement of the operation unit 21, the display unit 22 selectively exposes one of the two notations (“presence” and “absence”) and selectively covers the other notation. is configured as For example, when the display unit 22 moves integrally with the operation unit 21, only one of the notations is exposed from the opening of the housing. For example, in a first state in which the operation unit 21 is at the first position, the notation "Present" on the display unit 22 is exposed, and in a second state in which the operation unit 21 is at the second position, "Exit" is displayed on the display unit 22. ” appears. As a result, the usage status of the seat 5 can be notified to the surroundings by the exposed notation on the display section 22 .

The power generation unit 23 is configured to generate power according to the user's input operation to the operation unit 21 . The power generation section 23 has, for example, a coil and a magnet. The magnet is configured to move along with the slide operation (input operation) of the operation unit 21 . A slide operation (input operation) to the operation unit 21 changes the distance between the coil and the magnet, thereby generating electric power by electromagnetic induction. Note that the power generation unit 23 may have a piezoelectric element and may be configured to generate vibration power by vibrating the piezoelectric element as the operation unit 21 moves.

The output unit 24 is a wireless communication module capable of transmitting wireless signals. The output unit 24 is configured to transmit a radio signal using power generated by the power generation unit 23 due to the movement of the operation unit 21 when the operation unit 21 moves.

That is, the operation information is information indicating the movement direction of the operation unit 21, and the operation unit 21 has changed from the first state to the second state, or the operation unit 21 has changed from the second state to the first state. or indicates In other words, the operation information indicates whether the position of the operation unit 21 after being moved by the input operation is the first position (“Present” notation) or the second position (“Exiting” notation).

Identification information is information for identifying the operation device 2 . In this embodiment, a unique address assigned to each operating device 2 is used as identification information. The identification information is stored, for example, in a memory of the operating device 2 .

For example, when the user starts using the seat 5, the operation device 2 is input-operated so that the operation unit 21 changes from the second state (“leave seat” notation) to the first state (“presence” notation). By doing so, it outputs operation information and identification information. Further, for example, the operation device 2 is input-operated by the user so that the operation unit 21 changes from the first state (“presence” notation) to the second state (“remaining” notation) when the use of the seat 5 is finished. By doing so, the operation information and the identification information are output. In other words, the operation information output by the operation device 2 indicates the start and end of use of the seat 5 , in other words, the presence or absence of a person on the seat 5 .

The control device 3 includes a communication section 31 , a device control section 32 and a storage section 33 .

The control device 3 has, for example, a microcomputer with a processor and memory. The microcomputer functions as the device control unit 32 by executing the program stored in the memory by the processor. The program executed by the processor is recorded in advance in the memory of the microcomputer here, but may be recorded in a non-temporary recording medium such as a memory card and provided, or may be provided through an electric communication line such as the Internet. may be

That is, the communication section 31 acquires the operation information and the identification information from the operation device 2 . The communication unit 31 may directly receive the wireless signal output from the operation device 2 or may receive it via a relay device or the like. A communication method between the communication unit 31 and the relay device may be wireless communication or wired communication.

The device control section 32 is configured to control the lighting device 4 based on the operation information and identification information included in the wireless signal from the operation device 2 . Specifically, when the device control unit 32 receives the operation information and the identification information from the operation device 2 via the communication unit 31, the device control unit 32 refers to the storage unit 33 to search for the lighting device 4 to be controlled. Control is performed to turn on or off the obtained lighting equipment 4 .

The storage unit 33 is configured by a storage device selected from ROM (Read Only Memory), RAM (Random Access Memory), EEPROM (Electrically Erasable Programmable Read Only Memory), or the like.

The storage unit 33 stores correspondence relationships between the plurality of operating devices 2 and the plurality of lighting devices 4 . Each lighting device 4 is associated with a plurality of operating devices 2 . In this embodiment, the lighting device 4 is associated with the operating device 2 provided on the seat 5 directly below the lighting device 4 and the operating devices 2 around this operating device 2 . Specifically, the lighting device 4 includes an operation device 2 provided on the seat 5 directly below the device itself (the lighting device 4), and eight directions (0°, 45°, 90° °, 135°, 180°, 225°, 270°, 315°). Here, in FIG. 2, the upward direction, upper right direction, right direction, lower right direction, downward direction, left downward direction, left direction, and upper left direction with respect to the central operating device 2 are 0°, 45°, and 90°, respectively. °, 135°, 180°, 225°, 270°, and 315°.

Further, the tenth lighting device L10 is associated with the tenth operating device SW10 provided on the tenth seat D10 directly below. The tenth seat D10 is arranged at the lower end position in FIG. Therefore, the tenth lighting device L10 is positioned in five directions (0°, 45°, 90°, 270°, 315°) out of the eight directions around the tenth seat D10. , fourteenth and fifteenth operating devices SW4, SW5, SW9, SW14 and SW15.

Further, the storage unit 33 stores the operating state (at-seat state, away state) of each of the plurality of operation devices 2 and the operating state (lighting state, off-state) of each of the plurality of lighting devices 4 . Specifically, the storage unit 33 stores a data table that associates the operation state of each lighting device 4 with the operation state of the corresponding operation device 2 (see Table 1).

In Table 1, the operating state of each operating device 2 is the absent state, and the operating state of each lighting device 4 is the off state.

When the device control unit 32 receives the operation information and the identification information from the operation device 2, the device control unit 32 refers to the data table stored in the storage unit 33 to search for the lighting device 4 to be controlled, and performs the control obtained by the search. Control is performed to turn on or off the target lighting device 4 .

The device control unit 32 searches for a plurality of lighting devices 4 corresponding to the operation device 2 that has been input-operated. Then, if the operation information indicates that the position of the operation unit 21 after being moved by the input operation is the first position (notation of “presence”), the device control unit 32 selects the plurality of positions obtained by the search. Lighting control for lighting all the lighting devices 4 is performed. At this time, if the lighting device 4 is already in the lighting state, the lighting state of the lighting device 4 is maintained.

Further, when the operation information indicates that the position of the operation unit 21 after being moved by the input operation is the second position (notation “leave”), the device control unit 32 controls each lighting device obtained by the search. 4 is extinguished when all of the plurality of corresponding operation devices 2 are in the second state (leaving state). The device control unit 32 maintains the lighting state of each lighting device 4 obtained by the search if at least one of the corresponding plurality of operating devices 2 is in the first state (the presence state). Let

The detailed operation of the device control unit 32 will be described in the following operation example section.

(Operation example)
Next, an operation example of the control system 1 of this embodiment will be described with reference to FIGS. 3A to 3D. 3A to 3D schematically show the position and operating state (lighting state, light-out state) of each lighting device 4. FIG. 3A to 3D, the lighting state of the illumination device 4 is indicated by dot hatching.

Here, as an initial state, it is assumed that all the operation devices 2 are in the absent state and all the lighting devices 4 are in the off state (see FIG. 3A).

First, assume that the first user (first user) uses the thirteenth seat D13. The first user performs an input operation on the thirteenth operating device SW13 provided on the thirteenth seat D13 so as to change from the second state (away state) to the first state (presence state). Thereby, the thirteenth operation device SW13 outputs the operation information and the identification information to the control device 3 .

The control device 3 receives operation information and identification information from the thirteenth operation device SW13. The device control unit 32 refers to the database of the storage unit 33 (see Table 1) to search for the lighting device 4 corresponding to the thirteenth operating device SW13. The lighting devices 4 corresponding to the thirteenth operating device SW13 are the seventh to ninth, twelfth to fourteenth, seventeenth to nineteenth lighting devices L7 to L9, L12 to L14, and L17 to L19.

Here, the operation information received by the control device 3 indicates that the position of the operation unit 21 after being moved by the input operation is the first position (notation of "presence"). Therefore, the device control unit 32 performs lighting control to light the 7th to 9th, 12th to 14th, 17th to 19th lighting devices L7 to L9, L12 to L14, and L17 to L19 obtained by the search. . By this lighting control, the seventh to ninth, twelfth to fourteenth, seventeenth to nineteenth lighting devices L7 to L9, L12 to L14, and L17 to L19 are turned on (see FIG. 3B). Also, the operating state of the operating device 2 and the operating state of the lighting device 4 stored in the storage unit 33 are updated (see Table 2).

Next, assume that a second user (second user) uses the tenth seat D10. The second user performs an input operation on the tenth operating device SW10 provided in the tenth seat D10 so as to change from the second state (away state) to the first state (presence state). Thereby, the tenth operation device SW10 outputs the operation information and the identification information to the control device 3 .

The control device 3 receives operation information and identification information from the tenth operation device SW10. The device control unit 32 refers to the database (see Table 2) of the storage unit 33 to search for the lighting device 4 corresponding to the tenth operating device SW10. The lighting devices 4 corresponding to the tenth operating device SW10 are the fourth, fifth, ninth, tenth, fourteenth and fifteenth lighting devices L4, L5, L9, L10, L14 and L15.

Here, the operation information received by the control device 3 indicates that the position of the operation unit 21 after being moved by the input operation is the first position (notation of "presence"). Therefore, the device control unit 32 performs lighting control for lighting the fourth, fifth, ninth, tenth, fourteenth, and fifteenth lighting devices L4, L5, L9, L10, L14, and L15 obtained by the search. . By this lighting control, the fourth, fifth, ninth, tenth, fourteenth, and fifteenth lighting devices L4, L5, L9, L10, L14, and L15 are turned on (see FIG. 3C). Here, since the ninth and fourteenth lighting devices L9 and L14 are already in the lighting state, the lighting state is maintained. Also, the operating state of the operating device 2 and the operating state of the lighting device 4 stored in the storage unit 33 are updated (see Table 3).

Next, it is assumed that the first user who has been using the thirteenth seat D13 leaves the seat. The first user performs an input operation on the thirteenth operating device SW13 provided on the thirteenth seat D13 so as to change from the first state (presence state) to the second state (absence state). Thereby, the thirteenth operation device SW13 outputs the operation information and the identification information to the control device 3 .

The control device 3 receives operation information and identification information from the thirteenth operation device SW13. The device control unit 32 refers to the database (see Table 3) of the storage unit 33 to search for the lighting device 4 corresponding to the thirteenth operating device SW13. The lighting devices 4 corresponding to the thirteenth operating device SW13 are the seventh to ninth, twelfth to fourteenth, seventeenth to nineteenth lighting devices L7 to L9, L12 to L14, and L17 to L19.

Then, the device control unit 32 responds to each of the 7th to 9th, 12th to 14th, 17th to 19th lighting devices L7 to L9, L12 to L14, and L17 to L19 obtained by the search. The operating states of the plurality of operating devices 2 to be operated are confirmed. For each lighting device 4 obtained by the search, the device control unit 32 sets all of the plurality of operating devices 2 corresponding to the plurality of operating devices 2 except for the thirteenth operating device SW13 to the absent state. If there is, extinguishing control is performed to extinguish the corresponding lighting equipment 4 . In addition, for each lighting device 4 obtained by the search, the device control unit 32 selects at least one operating device 2 among the plurality of corresponding operating devices 2 excluding the thirteenth operating device SW13. is in the occupied state, the lighting state of the corresponding lighting device 4 is maintained.

Here, each of the seventh, eighth, twelfth, thirteenth, seventeenth to nineteenth lighting devices L7, L8, L12, L13, L17 to L19 has a plurality of corresponding operating devices 2 (thirteenth operating device 13SW13 ) is in the away state. Therefore, the device control unit 32 performs extinguishing control to extinguish the seventh, eighth, twelfth, thirteenth, seventeenth to nineteenth lighting devices L7, L8, L12, L13, and L17 to L19. By this extinguishing control, the seventh, eighth, twelfth, thirteenth, seventeenth to nineteenth lighting devices L7, L8, L12, L13, and L17 to L19 are turned off (see FIG. 3D). Each of the ninth and fourteenth lighting devices L9 and L14 includes a tenth operating device SW10 that is in a seated state in the corresponding plurality of operating devices 2 . Therefore, the device control section 32 maintains the lighting states of the ninth and fourteenth lighting devices L9 and L14 (see FIG. 3D). Also, the operating state of the operating device 2 and the operating state of the lighting device 4 stored in the storage unit 33 are updated (Table 4).

In the control system 1 of this embodiment, an operating device 2 is arranged on each seat 5 . Each operation device 2 functions as a switch device for turning on or off the nearest lighting device 4 and surrounding lighting devices 4 . As a result, only the lighting devices 4 around the seat 5 where the passenger is seated are turned on, so unnecessary lighting devices 4 can be turned off, and energy saving can be achieved.

Also, when the user leaves the seat, the lighting equipment 4 except for the area around the seat 5 where the user is still present is turned off. Therefore, the surrounding lighting device 4 remains lit for the user who is present at the seat, so that the feeling of strangeness due to the lighting device 4 being turned off is reduced.

(Modification)
Modifications of the control system 1 of this embodiment will be described below.

The device control unit 32 may turn on all of the plurality of lighting devices 4 when the proportion of the lighting devices 4 in the lighting state (lighting ratio) among the plurality of lighting devices 4 is equal to or greater than the ON threshold.

As the number of users increases, the number of operating devices 2 that are in a seated state increases, so the number of lighting devices 4 that are in a lighting state also increases. The device control unit 32 calculates the proportion (lighting ratio) of the lighting devices 4 in the lighting state among the plurality of lighting devices 4 (the first to twenty-fifth lighting devices L1 to L25), and calculates the lighting ratio and the predetermined ON threshold. compare. When the lighting ratio becomes equal to or higher than the ON threshold, the device control unit 32 collectively turns on all of the plurality of lighting devices 4 (first to twenty-fifth lighting devices L1 to L25). In other words, the equipment control unit 32 also turns on the lighting equipment 4 that does not correspond to the operating device 2 in the presence state. This suppresses sparse lighting when the number of occupied seats 5 is relatively large.

Furthermore, the device control unit 32 determines that the ratio (extinction ratio) of the lighting devices 4 for which all of the two or more corresponding operation devices 2 are in the absent state (second state) among the plurality of lighting devices 4 is equal to or greater than the OFF threshold. , the lighting device 4 in which all of the two or more corresponding operation devices 2 are in the away state (second state) may be turned off.

Assume that the user leaves the seat after all of the plurality of lighting devices 4 are turned on by the collective ON control described above. As a result, the number of operating devices 2 in the away state increases. As a result, among the plurality of lighting devices 4, the number of lighting devices 4 for which two or more corresponding operation devices 2 are all in the absent state increases. The device control unit 32 determines the proportion of the lighting devices 4 (the first to twenty-fifth lighting devices L1 to L25) in which all of the two or more corresponding operation devices 2 are in the absent state (light-out ratio). is calculated, and the light-off ratio is compared with a predetermined off-threshold value. When the ratio of light-out becomes equal to or greater than the off-threshold value, the device control unit 32 performs individual off-control to turn off the lighting devices 4 among the plurality of lighting devices 4 for which all of the two or more corresponding operation devices 2 are in the absent state. conduct. As a result, when the state in which the number of seats 5 present is relatively large changes to the state in which the number of seats 5 absent is relatively large, the lighting devices 4 except for the surroundings of the seats 5 present are extinguished. be done. Therefore, energy saving can be achieved.

Note that the ON threshold [%] is preferably a value different from the value obtained by subtracting the OFF threshold [%] from 100%. For example, when both the ON threshold and the OFF threshold are 50%, if the lighting ratio and the OFF ratio change around 50% due to the increase or decrease in the number of occupied seats 5, the lighting device 4 may be repeatedly turned on/off. be. Therefore, in order to suppress the number of times the lighting device 4 is turned on/off, the ON threshold [%] is preferably a value different from the value obtained by subtracting the OFF threshold [%] from 100%. Also, the ON threshold [%] is preferably larger than the value obtained by subtracting the OFF threshold [%] from 100%.

Moreover, the plurality of lighting devices 4 may be classified into a plurality of groups, and the device control section 32 may be configured to perform collective ON control and individual OFF control for each of the plurality of groups.

For example, it is assumed that there are multiple offices 50 and multiple lighting devices 4 are provided in each of the multiple offices 50 . A plurality of lighting devices 4 installed in one office 50 are classified into one group. In other words, each of the offices 50 is provided with a plurality of lighting devices 4 as one group. A plurality of operating devices 2 are provided in each of the plurality of offices 50 . Each of the plurality of operating devices 2 corresponds to lighting equipment 4 provided in the same office 50 as the own device (operating device 2).

The device control unit 32 controls the plurality of lighting devices 4 provided in each office 50 based on the input operations of the plurality of operation devices 2 provided in the same office 50 . In addition, the device control unit 32 performs collective ON control and individual OFF control for each of the plurality of offices 50 (each group). When the ratio of the lighting devices 4 in the lighting state (lighting ratio) out of the plurality of lighting devices 4 belonging to one group is equal to or higher than the ON threshold, the device control unit 32 turns off all of the plurality of lighting devices 4 belonging to the group. Collectively ON control is performed to turn on the LEDs.

A control method according to one aspect provides a control method for controlling a plurality of lighting devices based on operation states of a plurality of operation devices whose operation states change between a first state (seat state) and a second state (away state) due to an input operation. It includes a control step for controlling the operation state of the device 4 to switch between an ON state (lighting state) and an OFF state (extinguishing state). Each of the plurality of lighting devices 4 corresponds to two or more operating devices 2 among the plurality of operating devices 2 . In the control step, when the operation state of the operation device 2 changes to the first state, the operation state and the corresponding operation state of the operation device 2 are stored in association with each of the plurality of lighting devices 4. With reference to section 33, the operation state of lighting device 4 corresponding to operation device 2 is set to the ON state. In the control step, when the operation state of the operation device 2 changes to the second state, the storage unit 33 is referred to, and the lighting device 4 corresponding to the operation device 2 changed to the second state is searched from the plurality of lighting devices 4.
