Description

Relaxation control system, relaxation control device, and relaxation control method

[0001] The present disclosure relates to a relaxation control system, a relaxation control device, and a relaxation control method for individually controlling the temperatures of multiple seats.

[0002] Some outdoor facilities, such as outdoor stadiums, have seats with heating or cooling functions installed in the spectator seats and player benches. However, when temperature control is performed on a more or less general basis, such as by area, the temperature control is extremely inefficient.

[0003] For this reason, technologies for individually controlling the temperatures of multiple seats have recently been proposed. For example, Patent Document 1 describes a technology in which a sheet-like device is installed in each of multiple seats, and the sheet-like device has a built-in heater and control unit, and the control unit controls the heater in the same sheet-like device.

[0004] Japanese Patent Application Laid-Open No. 2019-133572

[0005] However, in the technology described in Patent Document 1, the seat-like device installed in each of the multiple seats needs to have the function of controlling the heater in that seat, which makes each seat-like device expensive and poses an issue with the operating costs of the system as a whole.

[0006] Therefore, in view of the above-mentioned problems, the object of the present disclosure is to provide a relaxation control system, a relaxation control device, and a relaxation control method that can perform efficient temperature control for multiple seats equipped with heating or cooling functions while reducing operating costs.

[0007] A relaxation control system according to one embodiment comprises an optical fiber laid to pass through a plurality of seats equipped with a heating or cooling function; a communication unit that transmits pulsed light to the optical fiber and receives an optical signal from the optical fiber; a detection unit that detects whether or not a person is seated in each of the plurality of seats based on the optical signal received from the optical fiber; and a control unit that individually controls the heating or cooling function of a seat detected as occupied by the detection unit.

[0008] A relaxation control device according to one embodiment includes a communication unit that transmits pulsed light to an optical fiber laid to pass through a plurality of seats equipped with a heating or cooling function and receives an optical signal from the optical fiber; a detection unit that detects whether or not a person is seated in each of the plurality of seats based on the optical signal received from the optical fiber; and a control unit that individually controls the heating or cooling function of a seat detected as occupied by the detection unit.

[0009] One embodiment of a relaxation control method is a relaxation control method using a relaxation control device, and includes a communication step of transmitting pulsed light to an optical fiber laid so as to pass through a plurality of seats equipped with a heating or cooling function, and receiving an optical signal from the optical fiber; a detection step of detecting, for each of the plurality of seats, whether or not a person is seated in that seat based on the optical signal received from the optical fiber; and a control step of individually controlling the heating or cooling function of the seat for which occupancy is detected by the detection step.

[0010] According to the above-described aspects, it is possible to provide a relaxation control system, a relaxation control device, and a relaxation control method that can efficiently control the temperature of multiple seats equipped with heating or cooling functions while reducing operating costs.

[0012] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. Note that the following description and drawings have been omitted and simplified as appropriate for clarity of explanation. In addition, in the following drawings, the same elements are given the same reference numerals, and duplicate explanations are omitted as necessary.

[0013] First Embodiment First, a configuration example of a relaxation control system according to the first embodiment will be described. Fig. 1 is a diagram showing a configuration example of a relaxation control system according to the first embodiment. Fig. 2 is an explanatory diagram of the drawing elements shown in Fig. 1.

[0014] As shown in FIG. 1, the relaxation control system according to the first embodiment includes an optical fiber 20 , a communication unit 31 , a detection unit 32 , and a control unit 33 .

[0015] The optical fiber 20 is laid so as to pass through a plurality of seats 10. The plurality of seats 10 are installed, for example, in spectator seats or player benches in an outdoor facility such as an outdoor stadium. Here, the seats 10 are equipped with a heating / cooling device 11 that heats and cools the seating surface. The heating / cooling device 11 is realized by a heater, a cooling heater, or the like. As described above, in the example of FIG. 1 , the seat 10 has both a heating function and a cooling function, but this is not limited thereto, and the seat 10 may have either a heating function or a cooling function. Furthermore, the seat 10 is not limited to the function of heating and / or cooling the seating surface, and may also have a function of blowing hot air and / or cold air onto a person, for example.

[0016] As will be described later, the optical fiber 20 is used to detect the presence of a person (such as a spectator or a player in the example of FIG. 1 ) in the seat 10. For this purpose, the optical fiber 20 may be passed through the seat surface or back surface of the seat 10. In the example of FIG. 1 , the optical fiber 20 is passed through the seat surface of the seat 10.

[0017] The communication unit 31 transmits pulsed light to the optical fiber 20. Backscattered light is then generated as the pulsed light is transmitted through the optical fiber 20. The communication unit 31 receives the backscattered light from the optical fiber 20 as an optical signal.

[0018] The detection unit 32 can identify the position where the optical signal was generated (the distance of the optical fiber 20 from the communication unit 31) based on the time difference between the time when the pulsed light was transmitted from the communication unit 31 to the optical fiber 20 and the time when the optical signal was received by the communication unit 31 from the optical fiber 20. Therefore, the detection unit 32 can identify the optical signal generated in each of the multiple sheets 10 by comparing the position where the optical signal was generated with a correspondence table such as that shown in Fig. 3. The correspondence table of Fig. 3 may be stored in advance in a memory (not shown) or the like.

[0019] Therefore, the detection unit 32 identifies the optical signal generated by each of the plurality of seats 10, and detects whether or not a person is seated in that seat based on the identified optical signal.

[0020] When a person sits in the seat 10, vibrations and distortions occur in the seat 10. As a result of the vibrations and distortions, the characteristics (e.g., wavelength) of the optical signal transmitted through the optical fiber 20 passing through the seat 10 change.

[0021] Therefore, the detection unit 32 can detect the vibrations and distortions caused by sitting on each of the multiple seats 10 by analyzing the characteristics of the optical signals generated in each of the multiple seats 10 from the optical signals received by the communication unit 31.

[0022] Therefore, the detection unit 32 may detect whether a person is seated in each of the plurality of seats 10 by detecting vibrations and distortions generated in that seat 10. In this case, the detection unit 32 may detect occupancy by comparing the vibration pattern and distortion pattern generated in the seat 10 with vibration patterns and distortion patterns generated when a person is seated that have been previously learned by machine learning (pattern matching). Alternatively, the detection unit 32 may detect occupancy based on whether the vibration intensity and distortion amount generated in the seat 10 are within a predetermined range. Furthermore, the detection unit 32 is not limited to detecting occupancy using both vibration and distortion, and may detect occupancy using either vibration or distortion.

[0023] Furthermore, when a person sits in the seat 10, the person's body heat causes a temperature change in the seat 10. This temperature change also causes the characteristics (e.g., wavelength) of the optical signal transmitted through the optical fiber 20 passing through the seat 10 to change.

[0024] Therefore, the detection unit 32 can detect temperature changes resulting from seating on each of the plurality of seats 10. Therefore, the detection unit 32 may detect whether a person is seated on each of the plurality of seats 10 by detecting not only the vibrations and distortions generated in each of the plurality of seats 10 but also the temperature generated in each of the plurality of seats 10. In this case, the detection unit 32 may detect seating by comparing the vibration pattern, distortion pattern, and temperature pattern generated in each of the seats 10 with the vibration pattern, distortion pattern, and temperature pattern generated when a person is seated that have been learned by machine learning in advance (pattern matching). Alternatively, the detection unit 32 may detect seating based on whether the vibration intensity, distortion amount, and temperature generated in each of the seats 10 are within a predetermined range.

[0025] In this way, by detecting seating using not only the vibrations and distortions generated in the seat 10 but also the temperature, the possibility of falsely detecting that a person is seated when a large or heavy item is placed on the seat is reduced, thereby improving the accuracy of seating detection.

[0026] To provide the seat heating service or seat cooling service, the control unit 33 individually controls the heating function or cooling function of the plurality of seats 10. Here, controlling the heating function or cooling function means, for example, turning the heating function or cooling function on or off or adjusting the temperature according to the outdoor temperature or the like.

[0027] Specifically, when the detection unit 32 detects that an occupant is seated in any of the seats 10, the control unit 33 individually controls the heating function or cooling function of the seat 10. The examples in Figures 1 and 2 are based on the assumption that the outdoor temperature is low, such as in winter, and the control unit 33 individually controls the heating function of the seat 10 to provide the seat heating service.

[0028] The communication unit 31, the detection unit 32, and the control unit 33 may be provided in the same device or in separate devices. The detection unit 32 and the control unit 33 may also be provided on the cloud.

[0029] Next, a description will be given of an example of a schematic flow of operations of the relaxation control system according to the embodiment 1. Fig. 4 is a flow chart showing an example of a schematic flow of operations of the relaxation control system according to the embodiment 1.

[0030] As shown in FIG. 4, first, the communication unit 31 transmits pulsed light to the optical fiber 20 (step S11), and receives backscattered light corresponding to the pulsed light from the optical fiber 20 as an optical signal (step S12).

[0031] Next, the detection unit 32 identifies the optical signal generated by each of the plurality of seats 10, and detects whether or not a person is seated in that seat based on the identified optical signal (step S13).

[0032] Next, the control unit 33 determines whether or not there is a seat 10 for which an occupant has been detected by the detection unit 32 (step S14). If there is a seat 10 for which an occupant has been detected in step S14 (Yes in step S14), the control unit 33 individually controls the heating function or cooling function of the seat 10 for which an occupant has been detected (step S15).

[0033] As described above, according to the first embodiment, the communication unit 31 transmits pulsed light to the optical fiber 20 and receives backscattered light corresponding to the pulsed light as an optical signal from the optical fiber 20. The detection unit 32 detects, based on the optical signal, whether or not a person is seated in a specified seat 10 for each of the plurality of seats 10. The control unit 33 individually controls the heating or cooling function of the seat 10 for which occupancy is detected.

[0034] This allows for efficient temperature control because the heating or cooling function can be controlled individually for each of the seats 10. Furthermore, because the control unit 33 collectively controls the heating or cooling function, there is no need for each seat 10 to have a function for controlling the heating or cooling function. This allows for reduced operating costs for the entire system.

[0035] <Embodiment 2> Next, a configuration example of a relaxation control system according to embodiment 2 will be described. Fig. 5 is a diagram showing a configuration example of a relaxation control system according to embodiment 2. Fig. 6 is an explanatory diagram of the drawing elements shown in Fig. 5.

[0036] As shown in Figure 5, the relaxation control system of this embodiment 2 differs from the configuration of Figure 1 of the above-mentioned embodiment 1 in that the seat 10 is equipped with a monitor 12 and a speaker 13.

[0037] The monitor 12 is installed on the seat 10 to provide a monitoring service to a person seated in the seat 10. The monitor 12 may be installed in any location and in any manner on the seat 10.

[0038] The speaker 13 is installed in the seat 10 to provide an audio service to a person seated in the seat 10. The speaker 13 may be installed in any location and in any manner on the seat 10. In the example of Fig. 5, the speaker 13 is installed, but headphones may be installed instead of or in addition to the speaker 13.

[0039] The control unit 33 can provide, in the seat 10, a monitoring service using the monitor 12 installed in the seat 10, and an audio service using the speaker 13 (or headphones, not shown) installed in the seat 10. In this way, in the examples of Figures 5 and 6, the control unit 33 can provide both the monitoring service and the audio service, but this is not limiting, and the control unit 33 may be capable of providing either the monitoring service or the audio service.

[0040] Specifically, when there is a seat 10 in which an occupant is detected by the detection unit 32, the control unit 33 provides a monitoring service or an audio service in the seat 10 in which an occupant is detected. However, this is not limited to this, and the control unit 33 may provide both the monitoring service and the audio service in the seat 10 in which an occupant is detected.

[0041] For example, when a sporting event or the like is being held at an outdoor facility, the control unit 33 may provide live video of the game as a monitor service or live audio of the game as an audio service at the seat 10 where occupancy is detected.

[0042] Next, a description will be given of an example of a schematic flow of operations of the relaxation control system according to the second embodiment. Fig. 7 is a flow chart showing an example of a schematic flow of operations of the relaxation control system according to the second embodiment.

[0043] As shown in Fig. 7, steps S21 to S24 are first performed, which are similar to steps S11 to S14 in Fig. 4 of the first embodiment. If step S24 detects that an occupant is seated in a seat 10 (Yes in step S24), the control unit 33 individually controls the heating or cooling function of the seat 10 in which an occupant is detected (step S25), similar to step S15 in Fig. 4 of the first embodiment. Furthermore, the control unit 33 provides a monitoring service using the monitor 12 or an audio service using the speaker 13 (or headphones, not shown) in the seat 10 in which an occupant is detected (step S26).

[0044] As described above, according to the second embodiment, the control unit 33 provides a monitor service using the monitor 12 or an audio service using the speaker 13 (or headphones not shown) in the seat 10 where occupancy is detected.

[0045] This makes it possible to provide additional services such as a monitoring service or an audio service to the person seated in the seat 10. Other effects are the same as those of the first embodiment described above.

[0046] <Other Embodiments> In the above-described embodiment, the communication unit 31, detection unit 32, and control unit 33 are provided separately, but this is not limiting. The communication unit 31, detection unit 32, and control unit 33 may be provided in the same device. Fig. 8 shows an example configuration of a relaxation control system in which the communication unit 31, detection unit 32, and control unit 33 are provided inside the relaxation control device 30. Note that in the relaxation control system shown in Fig. 8, the seat 10 may be provided with a monitor 12 and speaker 13, as in the second embodiment described above.

[0047] In the above-described embodiment, the present disclosure has been described as being applied to seats installed in outdoor facilities such as outdoor stadiums, but is not limited thereto. For example, the present disclosure can also be applied to seats in vehicles (cars, buses, trains, airplanes, etc.).

[0048] <Hardware configuration of relaxation control device according to embodiment> Next, an example of the hardware configuration of a computer 90 that realizes the relaxation control device 30 (Fig. 8) according to the other embodiment described above will be described.
