DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. The embodiment described below has technically preferable limitations for carrying out the present invention, but does not limit the scope of the invention to the following. In all drawings used to explain the following embodiments, the same reference numerals are used for similar parts unless otherwise specified. In the following embodiments, repeated explanations of similar configurations and operations may be omitted.

[0012] [First embodiment] The control system 1 is a system for controlling air conditioning equipment and lighting equipment installed in a facility. In this embodiment, a case where the control system 1 is applied to a terminal building of an airport will be described. In the following description, the terminal building of an airport will also be simply referred to as a "terminal building."

[0013] A terminal building is composed of a plurality of virtually divided areas. FIG. 1 and FIG. 2 are diagrams showing an example of a virtually divided area in a terminal building. In a departure lobby of a terminal building, for example, as shown in FIG. 1, areas E1 to E21 may be set by dividing the area in accordance with the arrangement of boarding gates. In an arrival lobby of a terminal building, for example, as shown in FIG. 2, areas E22 to E33 may be set by dividing the area in accordance with the arrangement of turntables installed in a baggage claim area. As another example, a terminal building may be divided into areas to set area E in accordance with the arrangement of lighting equipment or air conditioning equipment. How to divide the areas is determined in advance by, for example, an administrator of the control device 10. Information on the predetermined area division is stored in, for example, a storage unit (not shown) of the control device 10. The control system 1 controls the lighting equipment and air conditioning equipment installed in each divided area.

[0014] (Configuration of control system 1) First, the control system 1 of the present embodiment will be described with reference to Fig. 3 and Fig. 4. Fig. 3 is an explanatory diagram for explaining the control system 1 in the present disclosure. Fig. 4 is a block diagram for explaining an example of the configuration of the control system 1 according to the present disclosure.

[0015] The control system 1 includes a control device 10 and a surveillance camera 41. The control device 10, the control plan storage unit 30, and the surveillance video storage unit 40 are communicably connected to each other via a network NW. In this embodiment, the control plan storage unit 30 and the surveillance video storage unit 40 are configured as independent units, but they may be stored in a single storage device. Furthermore, the control plan storage unit 30 and the surveillance video storage unit 40 may be configured to be built into the control device 10.

[0016] The control device 10 is a device that controls the air conditioning equipment 60 and the lighting equipment 50. Therefore, the control device 10 is connected to the air conditioning equipment 60 and the lighting equipment 50 so as to be able to communicate with each other. The control device 10 is realized by a device such as a server, a cloud, or a personal computer (PC). The configuration of the control device 10 will be described later.

[0017] The control plan storage unit 30 is a database that stores the control plan for the lighting devices 50 and the control information for the air conditioners 60. The control plan for the lighting devices 50 and the control plan for the air conditioners 60 are assumed to be determined in advance by, for example, an administrator of the control device 10.

[0018] An example of the control plan for the lighting device 50 is shown in Fig. 6. The control plan for the lighting device 50 includes at least identification information of the divided areas, date and time information, and information on the maintained illuminance. In the example of Fig. 6, the identification information of the divided areas indicates "terminal information" and "boarding gate number". Also, in the example of Fig. 6, the date and time information indicates "date" and "time". In the example of Fig. 6, a maintained illuminance of 0 [lx] means that the lighting device 50 is turned off.

[0019] The control plan of the lighting device 50 is planned to change the maintenance illuminance according to the time period during which each area is used. For example, the control plan is planned to turn off the lighting device 50 during the time period during which the area is expected not to be used for a while. If the time period during which the area is expected not to be used is short, the control plan may be planned to lower the value of the maintenance illuminance (for example, 50 [lx]) without turning off the lighting device 50. During the time period during which the area is used, the maintenance illuminance of the lighting device 50 is planned to be the recommended setting value (for example, 500 [lx]). For example, in the case of a departure lobby, the time period before and after the departure time of an airplane is the time period during which the area near the boarding gate is used, so the maintenance illuminance is planned to be 500 [lx]. Other time periods are not used, so the maintenance illuminance is planned to be 0 [lx]. For example, in the case of an arrival lobby, the area is used for a while from the arrival time of the airplane using the area, so the maintenance illuminance is planned to be 500 [lx]. Since the room is not in use outside of these times, the maintained illuminance is planned to be 0 [lx].

[0020] An example of the control information for the air conditioner 60 is shown in Fig. 7. As shown in Fig. 7, the control information for the air conditioner 60 is information that links the illuminance to be maintained of the lighting device 50 with the set temperature of the air conditioner 60. The air conditioner 60 is controlled according to the illuminance to be maintained of the lighting device 50. In other words, the air conditioner is controlled in conjunction with the control of the lighting device. For example, when the lighting device 50 is turned off, the set temperature of the air conditioner 60 is changed in conjunction with this to the recommended temperature for energy saving (e.g., 28 degrees).

[0021] The surveillance video storage unit 40 is a database that stores surveillance video acquired from a surveillance camera 41 installed in a terminal building. There may be one or more surveillance cameras 41. The surveillance camera 41 acquires images of a number of virtually divided areas. The images acquired by the surveillance camera 41 are transmitted to the surveillance video storage unit 40. The information stored in the surveillance video storage unit 40 is referenced by the prediction unit 11 of the control device 10.

[0022] The lighting device 50 is a lighting device installed in the terminal building. The lighting device 50 may be singular or plural. The air conditioning device 60 is an air conditioning device installed in the terminal building. The lighting device 50 may be singular or plural. Information indicating the locations of the lighting devices 50 and the air conditioning devices 60 is stored in, for example, a memory (not shown) held by the control unit 13 of the control device 10.

[0023] (Configuration of control device 10) Next, the control device 10 of the present embodiment will be described with reference to Fig. 4 and Fig. 5. The control device 10 includes a prediction unit 11, a plan modification unit 12, and a control unit 13.

[0024] The prediction unit 11 is an example of a prediction means for predicting the degree of congestion in each area of ​​a facility consisting of multiple areas, using movement information of facility users. The prediction unit 11 predicts the degree of congestion for a predetermined period including the current time. The degree of congestion refers to the density of people in each area. For example, the degree of congestion is expressed as a numerical value from 0 to 1 as shown in FIG. 8. A higher value of the degree of congestion means a higher degree of congestion, i.e., a higher density of people.

[0025] The predetermined period including the current time is a period between the current time and a time in the future from the current time. The future time is determined in advance by an administrator of the control device 10. For example, the prediction unit 11 predicts the congestion degree from the present to one hour later.

[0026] The facility user's movement information is information related to the movement of the facility user within the facility. In this embodiment, the facility user's movement information refers to images from the surveillance camera 41 stored in the surveillance video storage unit 40. It should be noted that the facility user's movement information is not limited to the above-mentioned examples. For example, the facility user's movement information may be passenger check-in information or gate passage information. A method of using this information will be described later in the second embodiment.

[0027] The prediction unit 11 predicts the degree of congestion of each area using the images stored in the surveillance video storage unit 40. For example, as disclosed in Patent Document 1, the prediction unit 11 may predict the flow of people and predict the degree of congestion of each area using the predicted flow of people. In another example, the prediction unit 11 may calculate the current number of people in each area from the images of the surveillance camera 41 and predict the degree of congestion of each area using the calculated number of people. The prediction unit 11 predicts the degree of congestion of each area at a time interval predetermined by the administrator of the control device 10.

[0028] The plan modification unit 12 is an example of a plan modification means that modifies the control plan of the lighting devices 50 installed in each area in accordance with the congestion degree predicted by the prediction unit 11. The plan modification unit 12 refers to the control plan of the lighting devices 50 stored in the control plan storage unit 30. The plan modification unit 12 refers to the congestion degree predicted by the prediction unit 11 and the control plan of the lighting devices 50, and modifies the control plan based on a predetermined rule.

[0029] A specific example in which the plan change unit 12 changes the control plan for the lighting device 50 will be described with reference to FIG. 6, FIG. 8, and FIG. 9. In the area of ​​the boarding gate number 160 of the terminal T1, a lighting control plan as shown in FIG. 6 is established. FIG. 8 shows an example of the congestion degree predicted by the prediction unit 11 for this area. For example, it is assumed that a rule is determined in advance such that the maintenance illuminance is set to 500 [lx] when the congestion degree is 0.3 or more, and the maintenance illuminance is set to 0 [lx] when the congestion degree is less than 0.3. The plan change unit 12 refers to the congestion degree predicted by the prediction unit 11, and specifies that the congestion degree will be 0.3 or more at 12:55. The plan change unit 12 also specifies that the congestion degree will be less than 0.3 at 13:35. The plan change unit 12 changes the control plan for the lighting device 50 as shown in FIG. 9 based on the time determined based on the predetermined rule. The plan change unit 12 may link the post-plan change time to the control plan stored in the control plan memory unit 30, as in the example of Figure 9, or may change the control plan stored in the control plan memory unit 30 by overwriting it.

[0030] The control unit 13 is an example of a control means that controls the lighting devices 50 based on the control plan changed by the plan changing unit 12, and controls the air conditioners 60 in conjunction with the control of the lighting devices 50. The control unit 13 controls the lighting devices by referring to the changed control plan. The control unit 13 also controls the air conditioners 60 to be in conjunction with the lighting devices 50 by referring to the changed control plan for the lighting devices 50 and control information for the air conditioners 60.

[0031] (Operation of the control device 10) Next, an example of the operation of the control device 10 in this embodiment will be described with reference to Fig. 10. Fig. 10 is a flowchart showing an example of the operation of the control device 10 according to this embodiment.

[0032] First, the prediction unit 11 predicts the degree of congestion in each area of ​​a facility consisting of a plurality of areas, using movement information of facility users (step S11).

[0033] Next, the plan modification unit 12 modifies the control plan of the lighting devices 50 installed in each area according to the congestion level predicted in step S11 (step S12). For example, the plan modification unit 12 modifies the control plan according to the congestion level value calculated by the prediction unit 11 and a threshold value determined in advance for each maintained illuminance.

[0034] Next, the control unit 13 controls the lighting devices 50 based on the changed control plan (step S13). Furthermore, the control unit 13 controls the air conditioners 60 in conjunction with the control of the lighting devices 50 (step S14). After completing the process of step S14, the control device 10 ends the process.

[0035] (effect) The control device of this embodiment is configured as described above. Next, the effects of the control device of this embodiment will be described.

[0036] The control device of this embodiment includes a prediction unit, a plan change unit, and a control unit. The prediction unit predicts the degree of congestion in each area of ​​a facility consisting of a plurality of areas by using movement information of facility users. The plan change unit changes the control plan of the lighting devices installed in each area according to the degree of congestion predicted by the prediction unit. The control unit controls the lighting devices based on the control plan changed by the plan change unit, and controls the air conditioner in conjunction with the control of the lighting devices. The control plan of the lighting devices is planned to turn off the lighting devices 50 during a time period when it is expected that the area will not be used for a while. The control device of this embodiment predicts the degree of congestion in the area by the prediction unit. For example, when it is predicted that the degree of congestion in the area will be low before the planned time to turn off the lighting devices, the plan change unit changes the control plan so that the planned time to turn off the lighting devices is brought forward. The control device of this embodiment turns on the lighting devices in advance for areas expected to be used, and turns off the lighting devices in advance for areas expected not to be used. By being configured in this way, it is possible to make the user recognize whether the area will be used or not. This is useful, for example, when a boarding gate is changed at an airport. The control device of this embodiment changes the control plan for the lighting devices according to the predicted congestion level. By being configured in this way, the brightness of the lighting is appropriately changed according to whether or not people have actually gathered in the area, and it is possible to achieve both convenience for many facility users when many facility users gather and energy saving when not many facility users gather. Furthermore, the air conditioning device is controlled in conjunction with the control of the lighting device. It is assumed that the facility users do not head to an area where the lights are turned off. For example, in an airport terminal building, if the area near the boarding gate is turned off and the boarding time is still ahead, it is assumed that the facility users will head to another area where the lights are turned on. Therefore, even if the area where the lights are turned off is not at an appropriate temperature, the comfort of the facility users is not impaired. In other words, the control device of this embodiment can achieve further energy saving without impairing the comfort of the facility users.In addition, because air conditioning equipment is controlled in conjunction with lighting equipment, the temperature in areas where use is expected is controlled to the appropriate level by starting the air conditioning equipment in advance. Therefore, when facility users arrive in the area, the temperature is controlled to the appropriate level, allowing them to spend their time comfortably.

[0037] [Second embodiment] Next, a control system 2 and a control device 20 according to a second embodiment will be described with reference to the drawings. In this embodiment, a case where the control system 2 is applied to a terminal building of an airport will be described.

[0038] (Configuration of control system 2) 11 is a diagram for explaining an example of the configuration of the control system 2 according to this embodiment. The control system 2 is configured to have a control device 20 and a surveillance camera 41. It includes a surveillance video storage unit 40, lighting equipment 50, air conditioning equipment 60, a flight information storage unit 70, and a passenger information storage unit 80. The surveillance video storage unit, lighting equipment 50, and air conditioning equipment 60 are the same as those in the first embodiment, so detailed description will be omitted.

[0039] The flight information storage unit 70 is a database that stores flight information. The flight information is acquired, for example, from a flight information system (FIS) 71 owned by the terminal building, and stored in the flight information storage unit 70. When the flight information in the flight information system 71 is updated, the flight information storage unit 70 updates the stored information.

[0040] The flight information storage unit 70 specifically stores information such as the flight name of the aircraft, the departure time and arrival time of the aircraft, the change in the arrival time, the departure terminal or arrival terminal of the aircraft, the boarding gate number of the aircraft, and the operational status of the aircraft. The operational status of the aircraft specifically indicates the status of the operation of the aircraft, such as departed, arrived, and canceled. Figs. 12 and 13 show an example of flight information stored in the flight information storage unit 70. Fig. 12 is an example of flight information of an aircraft departing from the terminal building. Fig. 13 is an example of flight information of an aircraft arriving at the terminal building.

[0041] The passenger information storage unit 80 is a database that stores check-in information and gate passage information of passengers.

[0042] The passenger check-in information specifically includes information associating aircraft identification information with the number of people who have checked in. The number of people who have checked in is the number of people who will be boarding the aircraft. The aircraft identification information includes the aircraft's flight number and the aircraft's departure time. The passenger check-in information is obtained, for example, from a check-in information management system 81 owned by the airline, and stored in the passenger information storage unit 80.

[0043] Gate passage information is information acquired from gate 82 when a passenger passes through gate 82 where a boarding pass reader is installed. When gate 82 acquires new gate passage information, it sequentially transmits it to passenger information storage unit 80. Gate 82 is installed in a terminal building. A plurality of gates 82 are installed, for example, at security checkpoints, immigration checkpoints, boarding gates, etc. Gate passage information is log information that associates identification information of gate 82, the passing date and time when a passenger holds his / her boarding pass over gate 82, and identification information of the aircraft that the passenger will board (or has boarded). An example of gate passage information is shown in FIG. 15. As shown in FIG. 15, gate passage information includes the passing date and time and the identification information of the boarding pass reader that was passed through.

[0044] (Configuration of control device 20) Next, the configuration of the control device 20 will be described with reference to Fig. 16. The control device 20 includes a prediction unit 21, a plan modification unit 22, a control unit 23, and a planner 24.

[0045] The planner 24 is an example of a planning means that creates a control plan for the lighting devices 50 based on the flight information stored in the flight information storage unit 70. The planner 24 creates the control plan in accordance with predetermined rules.

[0046] The planning unit 24 creates a control plan for the lighting device 50 as shown in FIG. 6 based on, for example, the flight information shown in FIG. 12. For example, a rule is predefined such that the maintenance illuminance of the lighting device 50 is set to a recommended setting value 30 minutes before the departure time, and the lighting device 50 is turned off or the value of the maintenance illuminance is reduced 10 minutes after the departure time. The predefined rule may be a conditional rule. For example, the rule may be such that the lighting device 50 is turned off when the interval between the departure time and the next departure time is one hour or more, and the value of the maintenance illuminance is reduced when the interval between the departure time and the next departure time is less than one hour. The planning unit 24 plans to set the maintenance illuminance of the lighting device 50 to a recommended setting value (e.g., 500 [lx]) 30 minutes before the departure in accordance with the predefined rule. The planning unit 24 plans to turn off the lighting device 50 or the value of the maintenance illuminance is reduced (e.g., 50 [lx]) 10 minutes after the departure in accordance with the predefined rule.

[0047] The planning unit 24 creates a control plan for the lighting device 50 as shown in Fig. 14 based on, for example, the flight information shown in Fig. 13. For example, the planning unit 24 makes a plan to set the maintenance illuminance of the lighting device 50 to a recommended setting value (for example, 500 [lx]) 10 minutes after the arrival of the aircraft using the baggage claim area. For example, the planning unit 24 makes a plan to turn off the lighting device 50 20 minutes after turning on the lighting device 50.

[0048] The prediction unit 21 predicts the degree of congestion in each area using the movement information of the facility users. In this embodiment, the movement information of the facility users includes at least one of the images of the surveillance camera 41 stored in the surveillance video storage unit 40, the check-in information stored in the passenger information storage unit 80, and the gate passage information. A method for predicting the degree of congestion using the movement information of the facility users will be described below. Note that the method for predicting the degree of congestion using the images of the surveillance camera 41 stored in the surveillance video storage unit 40 has been described in the first embodiment, so a description thereof will be omitted here.

[0049] First, a method of predicting the degree of congestion in each area using check-in information will be described. The prediction unit 21 periodically refers to the passenger information storage unit 80 to obtain information on the time transition of the number of people who have completed check-in. The prediction unit 21 predicts the degree of congestion in each area based on the time transition of the number of people who have completed check-in. For example, the prediction unit 21 may use a trained congestion prediction model to predict the degree of congestion for a predetermined period including the present by inputting the time transition of the number of people who have completed check-in.

[0050] Next, a method for predicting the degree of congestion in each area using the gate passage information will be described. The prediction unit 21 refers to the passenger information storage unit 80 at regular intervals to obtain gate passage information. The gate passage information is information such as that shown in FIG. 15, which associates the identification information of the gate 82 with the passing date and time when the passenger held the boarding pass over the gate 82. The prediction unit 21 refers to the gate passage information to obtain the transition of the degree of congestion in each area. The prediction unit 21 predicts the degree of congestion in each area using the transition of the degree of congestion.

[0051] The plan modification unit 22 modifies the control plan for the lighting devices 50 created by the planner 24 in accordance with the congestion degree predicted by the predictor 21. The controller 23 controls the lighting devices 50 based on the control plan modified by the plan modification unit 22, and controls the air conditioners 60 in conjunction with the control of the lighting devices 50.

[0052] (Operation of the control device 20) Next, the operation of the control device 20 in this embodiment will be described with reference to Fig. 17. Fig. 17 is a flowchart showing an example of the operation of the control device 20 according to this embodiment.

[0053] The planner 24 creates a control plan for the lighting devices 50 installed in each area (step S21). Specifically, the planner 24 creates the control plan for the lighting devices 50 by referring to the flight information stored in the flight information storage unit 70.

[0054] Next, the prediction unit 21 predicts the congestion level of each area using the movement information of the facility users (step S22). The movement information of the facility users includes at least one of the images of the surveillance camera 41 stored in the surveillance video storage unit 40, the check-in information stored in the passenger information storage unit 80, and the gate passage information.

[0055] Next, the plan modification unit 22 modifies the control plan for the lighting devices 50 created by the planner 24 in accordance with the congestion degree predicted by the predictor 21 (step S23).

[0056] Next, the control unit 23 controls the lighting devices 50 based on the control plan changed by the plan change unit 22 (step S24). The control unit 23 also controls the air conditioners 60 in conjunction with the control of the lighting devices 50 (step S25). After completing the process of step S25, the control device 20 ends the series of processes described above.

[0057] (effect) The control device of this embodiment is configured as described above. In addition to the effects obtained from the control device of the first embodiment, the control device of this embodiment provides the following effects.

[0058] The control device in this embodiment includes a planning unit. The planning unit creates a control plan based on flight information. The flight information includes information on the operational status of an aircraft, such as flight cancellations, and information on time changes. By creating a plan based on the flight information, it is possible to prevent a situation in which, for example, when an aircraft flight is canceled, the lights in an area related to the flight are not turned off even though the area is not in use.

[0059] The control device in this embodiment includes a prediction unit. The prediction unit predicts the degree of congestion in each area of ​​a facility consisting of multiple areas using movement information of facility users. The movement information includes at least one of check-in information, passage information of gates installed in an airport, and video from a surveillance camera installed in the facility. When the movement information is check-in information, the prediction unit predicts the degree of congestion in each area using the number of people who have completed check-in as the check-in information. By using the check-in information, the number of people boarding or the number of people who have boarded the aircraft can be accurately grasped, and therefore the degree of congestion can be predicted more accurately.

[0060] (Modification) In the first and second embodiments, the control system is described as being applied to an airport terminal building, but it may be applied to other facilities without being limited to the above examples. The control device in the present disclosure is effective when applied to a facility such as an airport terminal building that is divided into multiple areas and whose congestion level changes over time. For example, the control system of the present disclosure may be applied to a facility such as a school. When applied to a school, the control plan for the lighting devices is created based on, for example, the school curriculum or timetable. The congestion level is predicted using information such as the video of a surveillance camera installed in the school or the number of students attending a lecture.

[0061] [Computer hardware configuration] The functions of each of the components in each of the embodiments of the present disclosure described above can be realized not only by hardware but also by a computer device and firmware based on program control.

[0062] Fig. 18 is a diagram showing an example of a hardware configuration in which a control device in the present disclosure is realized by a computer device 90 including a processor.
