[0001] The present invention relates to a building facility control system and a building facility control method. [Background technology]

[0002] Conventionally, air conditioners, elevators, and other equipment installed in buildings are operated according to a predetermined schedule. For example, air conditioners are controlled to start operating at a fixed time, such as 7:00 every morning.

[0003] In response to this, it has been proposed to control the air conditioners in each room in a building based on the schedules of people who are actually planning to enter the building, thereby enabling more appropriate management of building facilities. For example, Patent Document 1 discloses a technique for operating air conditioners according to the entry time by utilizing schedule information of people who are scheduled to enter a building, which is managed by a schedule management system. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2013-89206 A Summary of the Invention [Problem to be solved by the invention]

[0005] In recent years, the number of people in each room in a building has fluctuated irregularly and significantly due to the diversification of work styles, such as teleworking and working from home, especially in office buildings. For example, even in the same room, there are cases where many seats are unoccupied in a certain area, while relatively many seats are occupied in other areas. In such cases, if the air conditioners in each room in the building are operated under the same conditions, there will be some places where the temperature is appropriate and others where it is not, and there will be cases where the air conditioning in the rooms cannot be said to be properly controlled.

[0006] In addition to air conditioners, various building facilities are installed, such as lighting and elevators, and some of these facilities do not need to be controlled at the same timing as air conditioners. In this way, it is desirable to control building facilities in detail for each area and type of facility, but such detailed control has not been possible with conventional technology.

[0007] An object of the present invention is to provide a building equipment control system and a building equipment control method that enable detailed control of building equipment in accordance with actual conditions. [Means for solving the problem]

[0008] In order to solve the above problems, for example, the configurations described in the claims are adopted. The present application includes multiple means for solving the above problems, and one example thereof is a building equipment control system that controls equipment installed in a building, comprising: an information receiving unit that receives reservation information including a usage start time and a seat position from a seat reservation system; an information management unit that stores and manages reservation information and control mapping information including attribute information of the equipment installed in the building; and a control command unit that, when controlling the equipment based on the usage start time of the reservation information managed by the information management unit, issues a control command to start using the equipment at a time earlier than the usage start time of the seat by referring to the control mapping information stored in the information management unit; The building comprises a location information gateway which acquires location information of users inside the building, a number of people remaining determination unit which determines whether a person is remaining at a target seat based on the location information received from the location information gateway, a number of people counting unit which updates the number of reservations based on the reservation information stored in the information management unit, and a number of people comparison unit which compares the number of people remaining determined by the number of people remaining determination unit with the number of reservations obtained by the number of people counting unit, and the control command unit generates and controls a control command for changing the operating state of the equipment when the number of people comparison unit determines that a difference between the predetermined number of people remaining and the number of reservations continues for a certain period of time. Effect of the Invention

[0009] According to the present invention, in a space where each seat is provided, such as an office building, it is possible to appropriately control the building equipment corresponding to each seat, thereby realizing energy savings and providing a comfortable environment.

[Figure 10] FIG. 11 is a block diagram showing an example of the overall configuration of a building facility control system according to a modified example of an embodiment of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, an embodiment of the present invention (hereinafter, referred to as "this example") will be described with reference to the accompanying drawings.

[0012] [Overall system configuration] First, to give an overview of the system of this example shown in Fig. 1, an air conditioning and lighting control system 1, which is the center of the system, obtains reservation information for seats on each floor of a building through data linkage from a seat reservation system 2. Then, the air conditioning and lighting control system 1 stores the obtained data in a database within the air conditioning and lighting control system 1, which will be described later.

[0013] Furthermore, the air conditioning and lighting control system 1 transmits the stored reservation information to a control command server 8 that is installed in the local building 4 and issues control commands. The control command server 8 stores the received reservation information and controls the operation of the equipment based on the stored reservation information, pre-mapped seat information, and information detected by the position information sensor. Here, air conditioning and lighting equipment is used as an example, and the system in this example performs advance operation control of the air conditioning and lighting equipment, and controls suppression operation or stop operation when it detects the presence or absence of people.

[0014] Next, a specific configuration of the system of this embodiment will be described with reference to FIG. As shown in Fig. 1, the system in this example is composed of an air conditioning and lighting control system (center) 1, a seat reservation system 2, and multiple buildings 4, 5, and 6 in which on-site building facilities are installed and operated. There are many buildings (first building 4, second building 5, ... nth building 6: n is an arbitrary integer) controlled by the air conditioning and lighting control system 1, but the following explanation will be given of the configuration of the first building 4. Note that the second building 5 to the nth building 6 have the same configuration, so duplicate explanations will be omitted.

[0015] The air conditioning and lighting control system 1 has a master information database 1A and a reservation information database 1B. In the drawings, the database is represented as DB. The master information database 1A stores mapping information, which is master information for controlling the facilities of the buildings 4, 5, and 6. The reservation information database unit 1B stores reservation information transmitted from the seat reservation system 2. The air conditioning and lighting control system 1 manages and controls the facilities of the buildings 4, 5, and 6 based on the information stored in each of the databases 1A and 1B.

[0016] The seat reservation system 2 is a system that allows building users (employees) to reserve seats located in buildings 4, 5, and 6 based on their own work schedules. The seat reservation system 2 is composed of a seat reservation database 2A that stores seat reservation information, and a management terminal 2B that manages the reservation information. The management terminal 2B transmits the reservation information stored in the seat reservation database 2A to the air conditioning and lighting control system 1 via the Internet 3. As a result, the seat reservation system 2 and the air conditioning and lighting control system 1 link data and share information about the reservation information.

[0017] A building 4 that is the subject of management of the air conditioning and lighting control system 1 includes a communication device 7, a control command server 8, a management terminal 9, a location information gateway 10, a lighting control gateway 11, an air conditioning control gateway 12, an elevator control gateway 13, and an elevator control device 14. In the drawings, the gateway is represented as GW. The control command server 8 (control command unit) generates control commands for the building facilities in the building 4 and performs processing for transmitting the generated control commands. The communication device 7 is a network device for performing information reception processing and information transmission processing for exchanging data communication between the air conditioning / lighting control system 1 and the control command server 8. The management terminal 9 is a terminal for managing air conditioning, and is a computer terminal provided on-site for viewing the data stored on the control command server 8.

[0018] The location information gateway 10 processes location information data received from the connected receiving terminals 10Aa-10An and performs gateway processing to transmit the data to the control command server 8. The location receiving terminals 10Aa-10An are preferably arranged so as to be able to communicate with all seats in the building 4. The receiving terminals 10Aa to 10An also communicate wirelessly with transmitting terminals 10Ba to 10Bn that transmit location information owned by individuals who enter and leave the building 4 and use seats, and send the location information data of each transmitting terminal 10Ba to 10Bn to the location information gateway 10.

[0019] The lighting control gateway 11 performs a process of converting a control command for building equipment (lighting) generated from the control command server 8 into a processing message for actually controlling the lighting equipment 11A to 11N installed in the building 4. The air conditioning control gateway 12 performs processing to convert control commands for building facilities (air conditioning facilities) generated by the control command server 8 into processing messages for actually controlling the air conditioning facilities 12A to 12N. The elevator control gateway 13 performs a process of converting a control command for a building facility (elevator) generated by the control command server 8 into a processing message for controlling the elevator by the elevator control device 14. In addition, in FIG. 1, examples of building facilities are shown as air conditioning facilities, lighting facilities, and elevator facilities, but building facilities other than air conditioning facilities, lighting facilities, and elevator facilities may also be controlled by the control command server 8.

[0020] [Air conditioning and lighting control system configuration] FIG. 2 is a block diagram showing the configuration of the air conditioning and lighting control system 1. As shown in FIG. 2, the air-conditioning and lighting control system 1 includes an information management unit 1X and an information transmission unit 1Y. The information management section 1X includes a master information database 1A, a reservation information database 1B, and an information update section 1C that performs processing related to the data managed in each of the databases 1A, 1B. The master information database 1A holds mapping information for controlling devices for all buildings. The reservation information database 1B holds reservation information for seats in all buildings based on information from the seat reservation system 2. The information sending section 1D and the information receiving section 1E of the information transmitting section 1Y perform data transmission and reception processing with the seat reservation system 2 and the control command server 8.

[0021] [Configuration of the control server] FIG. 3 is a block diagram showing the configuration of the control command server 8. As shown in FIG. As shown in FIG. 3, the control command server 8 includes a control unit 8X, an information management unit 8Y, and an information transmission unit 8Z. The information transmission unit 8Z includes an information sending unit 8A and an information receiving unit 8B. The information transmission unit 8A performs information transmission processing when there is a data browsing request from the lighting control gateway 11, the air conditioning control gateway 12, or the management terminal 9. The information receiving unit 8B performs reception processing of information from the location information gateway 10, reception processing of device control results from the lighting control gateway 11 and the air conditioning control gateway 12, and reception processing of data transmitted from the air conditioning and lighting control system 1.

[0022] The control unit 8X is composed of a number-of-people comparison unit 8C, a device control unit 8D, a staying-number-of-people determination unit 8E, and a reservation-number counting unit 8F. The number-of-people comparing unit 8C performs an actual comparison between the reservation information stored in the information managing unit 8Y and the presence / absence status of people based on the position information. The device control unit 8D generates control commands for the building facilities (here, air conditioning facilities, lighting facilities, and elevator facilities).

[0023] The stayer number determining unit 8E performs a process of calculating and determining whether people are present or absent and how many people are staying, based on the position information stored in the information managing unit 8Y. The reservation number counting unit 8F counts reservation information for each seat in the building 4 from the reservation information for the building 4 delivered from the air conditioning and lighting control system 1 each time it is updated, and issues an update process command to the information management unit 8Y to update the stored reservation information.

[0024] The information management unit 8Y includes a master information database 8H, a reservation information database 8I, and an information update unit 8G. The information management unit 8Y holds the information stored in each of the databases 8H and 8I, and performs update processing (information management processing) of information to be newly stored in each of the databases 8H and 8I. The master information database 8H holds mapping information for controlling devices present in the information management unit 8Y. The reservation information database 8I holds reservation information within the building 4. The information update unit 8G refers to the reservation information database 8I that manages the reservation information within the building 4, performs editing processing to update the reservation information, and transmits the processing result as a response to the control unit 8X.

[0025] [Data table regarding seat reservation information] FIG. 4 shows the data structure of a reservation information data table relating to seat reservation information, which is held in the reservation information database 8I of the information management unit 8Y in the control command server 8. As shown in FIG. The reservation information data table is made up of fields including a building name 8Ia, a floor 8Ib, a seat number 8Ic, a user 8Id, a user ID 8Ie, a scheduled date 8If, a start time 8Ig, an end time 8Ih, and a pre-operation start time 8Ii.

[0026] The building name 8Ia indicates the name of the local building. The floor 8Ib indicates the floor on which the seat is located. The seat number 8Ic indicates a unique number indicating the reserved seat. The user 8Id indicates the name of the user who reserved the seat. The user ID 8Ie indicates an identification number for identifying the location information transmission terminal owned by the user 8Id. The location information transmission terminal here is, for example, a portable location information transmission terminal such as an employee ID card or a smartphone.

[0027] The scheduled date 8If, the start time 8Ig, and the end time 8Ih indicate the reservation date, the start time, and the end time of the reserved seat. The advance operation start time 8Ii is information indicating how many minutes before the reservation time advance operation is to start for the building equipment related to the corresponding seat. The time to start this advance operation is set based on the advance operation start time of the master information described next.

[0028] One record (one line of information) shown in Figure 4 indicates a reservation for one person, and if there are multiple reservations for one seating location, the record is updated by the information update unit 8G by generating records for the number of people.

[0029] [Master information data table] FIG. 5 shows the data structure of a master information data table (facility attribute data table) that is facility attribute information related to mapping information between building facilities and location information centers, which is managed in the master information database 8H in the control command server 8.

[0030] The master information data table stored in the master information database 8H has fields including a building name 8Ha, a floor 8Hb, a seat number 8Hc, a position information sensor 8Hd, a control device 8He, pre-operation necessity 8Hf, and a pre-operation start time 8Hg. The building name 8Ha indicates the local building name. The floor 8Hb indicates the floor where the seat is located. The seat number 8Hc indicates a unique number that indicates the seat.

[0031] The position information sensor 8Hd indicates the position information receiving terminals 10Aa to 10An associated with the seat indicated by the seat number 8Hc. The control device 8He indicates any one of the lighting equipment 11A to 11N and the air conditioning equipment 12A to 12N, which are building equipment associated with the seat indicated by the seat number 8Hc.

[0032] The advance operation necessity 8Hf indicates whether or not advance operation of the building equipment indicated by the control device 8He is required at the seat indicated by the seat number 8Hc. Pre-operation start time 8Hg indicates how many minutes in advance each building facility will be pre-operated when pre-operation necessity 8Hf indicates "necessary." For example, the first air conditioning unit on the first floor corresponding to seat numbers 001,002 in the ABC building is set to pre-operate 30 minutes before the start of use, and the first lighting unit on the first floor corresponding to the same seat numbers 001,002 is set to pre-operate 10 minutes before the start of use. For other seat numbers, the times for pre-starting the air conditioning equipment and lighting equipment corresponding to each seat are also set, but for all seats, the time for pre-starting the air conditioning equipment is set to be earlier than the time for pre-starting other equipment such as the lighting equipment (lighting start time). In this way, if the building equipment is air conditioning equipment, it is set to start up earlier than other building equipment such as lighting equipment so that the room will be at the set temperature at the reservation start time for each seat, and each seat can be made available in the appropriate condition at the reservation start time. For equipment that operates immediately upon sending a control command, such as lighting equipment, the pre-operation time can be kept to a minimum. Note that for equipment that operates immediately, such as lighting equipment, the pre-operation time can be set to 0 minutes so that it operates at the reservation start time.

[0033] The pre-operation start time 8Hg in the reservation information data table is calculated by referring to the master information database 8H, calculating how many minutes have passed since the pre-operation start time 8Hg from the current start time, and registering the pre-operation start time data.

[0034] [Data linking process for reservation information] Next, an example of processing related to data linkage in the air conditioning and lighting control system 1 based on usage reservation information from the seat reservation system 2 will be described with reference to the sequence diagram shown in Fig. 6. The left side of Fig. 6 shows the processing flow in the air conditioning and lighting control system 1, and the right side shows the processing flow in the seat reservation system 2.

[0035] First, when the seat reservation DB2A is updated, the seat reservation system 2 calls an API (application interface) and transmits the reservation information stored in the seat reservation DB2A to the air conditioning and lighting control system 1 (step S11). The air-conditioning and lighting control system 1 receives the reservation information transmitted in step S11 at the information receiving unit 1E. Then, the information updating unit 1C of the air-conditioning and lighting control system 1 writes the reservation information received from the seat reservation system 1 into the reservation information database 1B (step S12).

[0036] Next, the air-conditioning and lighting control system 1 searches for reservation information stored in the reservation information DB 1B under conditions related to the building 4 by the information updating unit 1C in the air-conditioning and lighting control system 1. The seat reservation information for building 4, which is the search result, is then transmitted to the control command server 8 in building 4 (step S13). Moreover, the air-conditioning and lighting control system 1 returns the above processing result (ACK) to the seat reservation system 1 (step S14).

[0037] The above steps S11 to S14 are a process flow when the transmitted reservation information is data relating to the next day or later, and there are also cases where the reservation information for the current day is updated. In this case, the same processing as steps S11 to S14 is performed when the reservation information is updated on the seat reservation system 2, but data is searched for using information about building 4 and the current date as conditions, and the subsequent processing of steps S15 to S19 is performed.

[0038] That is, when a change occurs in the reservation information on the day in the seat reservation system 2 (step S15), the API (application interface) is called and the reservation information is transmitted to the air-conditioning and lighting control system 1 (step S16). Then, the air conditioning and lighting control system 1 receives the reservation information transmitted in step S16 at the information receiving unit 1E, and the information updating unit 1C writes the received reservation information in the reservation information DB 1B (step S17).

[0039] Furthermore, the air-conditioning and lighting control system 1 updates the data of the usage reservation information existing in the reservation information DB 1B by the information update unit 1C and transmits it to the local server (control command server 8) (step S18).Then, the air-conditioning and lighting control system 1 returns a response to the seat reservation system 2 notifying that the data writing has been completed (step S19).

[0040] [From advance device control before use begins to processing after the start of the usage period] FIG. 7 shows an example of the processing flow when detecting the presence of a person in a room after the start of usage time zone, starting from advance equipment control before usage starts, assuming air conditioning control, as an example of building equipment. 7 shows, from the left, processing in the control command server 8, processing in the air conditioning control gateway 12, processing in the air conditioning equipment 12A to 12N, processing in the location information gateway 10, and processing in the receiving terminals 10Aa to 10An.

[0041] First, in the control command server 8, the device control unit 8D in the control unit 8X periodically refers to the utilization reservation information data table (FIG. 4) existing in the reservation information DB 8I of the information management unit 8Y (step S21). The control command server 8 determines from the usage reservation information data table referenced in step S21 that in building 4, the "ABC Building," the pre-operation start time 8Ii of the building equipment pre-operation will be required from "8:40 (21 / 08 / 20)" for the seat with seat number 8Ic "001" on the first floor (step S22).

[0042] Next, the control command server 8 refers to the facility attribute information data table (FIG. 5) existing in the master information DB 8H in the information management unit 8Y. In the example of FIG. 5, the position information sensor 8Hd that matches the seat number 8Hc "001" is the "first receiving terminal" and the control device 8He is the "first air conditioning" and the "first lighting", so the control command server 8 selects the "first air conditioning" and the "first lighting" as the building facilities to be operated (step S23).

[0043] Thereafter, when the preliminary-operation start time arrives, the equipment control unit 8D generates a control command for suppressed operation for the preliminary operation to the "first air conditioning" indicated in the column for the control device 8He in the data table in FIG. 5 (step S24). Then, the control command server 8 transmits the generated control command for the inhibited operation from the equipment control unit 8D via the information transmitting unit 8A of the information transmitting unit 8Z to the air conditioning control GW 12 (step S25). The air conditioning control GW12 that has received the control command converts it into transmission data for controlling the device of the "first air conditioning" and transmits the control command to the "first air conditioning" (step S26).

[0044] In accordance with the control command transmitted in step S26, the "first air conditioning" starts suppression operation (step S27). Then, the "first air conditioning" replies to the air conditioning control GW12 that it has responded normally by starting suppression operation (step S28). Then, the air conditioning control GW12 replies to the device control unit 8D of the control command server 8 with the control result for the "first air conditioning" (step S29).

[0045] Next, when the time comes to start using the seat in building 4 with seat number 8Hc "001" shown in Fig. 5, location information is transmitted from the location information transmission terminal "A000000000000001" of user ID 8Ie carried by the user shown in the user 8Id column in Fig. 4. At this time, the first receiving terminal 10Aa (see Fig. 1) detects the location information transmitted from the location information transmission terminal "A000000000000001" (step S30). The detection of the location information here means that the user who reserved the seat is present in the room in which the corresponding seat is located.

[0046] When presence is detected by acquiring the position information in step S30, the position information GW 10 transmits the position information data detected in step S30 to the number of people comparing unit 8C of the control unit 8X in the control command server 8 (step S31). The number of people comparison unit 8C that received the location information data transmitted in step S31 passes the location information data to the staying number of people determination unit 8E, and identifies the number of people detected to be in the room and the transmitting terminal. In addition, the reservation number of people count unit 8F of the control unit 8X refers to the facility attribute information data table (FIG. 5) existing in the master information DB 8H.

[0047] Then, the control command server 8 determines whether the user is present in the room by comparing the current reservation information for the seat with the seat number 8Ic "001" shown in Fig. 4, the determination by the number-of-remaining-persons determination unit 8E, and the data received from the reservation number counting unit 8F. At this time, the control command server 8 determines whether the presence of the user (person) continues for a certain period of time (step S32).

[0048] In step S32, when it is determined that the user has been present in the room for a certain period of time and that the room is occupied, the equipment control unit 8D refers to the equipment attribute information data table (FIG. 5) in the master information DB 8H and selects the equipment to be controlled (step S33). For example, when the position information sensor 8Hd that matches the seat number 8Hc "001" is the "first receiving terminal" and the control device 8He is the "first air conditioning" and the "first lighting", the control command server 8 selects the "first air conditioning" and the "first lighting" as the building equipment to be operated. Then, the device control unit 8D of the control unit 8X generates a normal operation control command for normal operation of the "first air conditioning" (step S34).

[0049] The control command for normal operation generated in step S34 is transmitted from the equipment control unit 8D via the information transmission unit 8A to the air conditioning control GW 12 (step S35). Then, the air conditioning control GW12 that received the control command converts this control command into transmission data for controlling the device for the "first air conditioning" and transmits it to the "first air conditioning" (step S36).

[0050] The "first air conditioning" starts normal operation in accordance with the control command sent in step S36 (step S37), and replies to the air conditioning control GW 12 that normal operation has started (step S38). The air conditioning control GW 12, which receives this reply, replies to the device control unit 8D of the control command server 8 with the control result for the "first air conditioning" control command (step S39).

[0051] In the flow shown in Fig. 7, the process for the "first air conditioning" which is an air conditioning facility has been described as an example, but the "first lighting" which is the lighting facility to be controlled in this embodiment is also controlled in a similar manner. However, as shown in the "pre-start time" column in Fig. 5, the pre-start times are different between the air conditioning facility and the other facilities, and a control command is sent to start the air conditioning facility earlier than the other facilities. The same process is used to control the operation of elevators. For example, the number of elevators in operation can be reduced during times when there are few building users, and increased during times when there are many building users. Furthermore, pre-operation and normal operation are performed in a similar process flow for other building facilities besides air conditioning equipment, lighting equipment, and elevators.

[0052] [Processing when no one is present] Next, an example of the process when it is detected that no one is present during the usage time period will be described with reference to Fig. 8. Fig. 8 uses air conditioning control as an example. 8, like FIG. 7, shows, from the left, processing at the control command server 8, processing at the air conditioning control GW 12, processing at the air conditioning equipment 12A to 12N, processing at the location information GW 10, and processing at the receiving terminals 10Aa to 10An.

[0053] After the seat in building 4 with seat number 8Hc “001” shown in FIG. 5 is actually unoccupied during the usage time, the “first receiving terminal” shown as receiving terminal 10Aa in FIG. 1 transmits the currently detected location information to the location information GW 10 (step S41). The position information GW 10, which has received the current position information data in step S41, transmits the position information data detected in step S41 to the number of people comparing unit 8C in the control command server 8 (step S42).

[0054] The number of people comparison unit 8C of the control unit 8X that received the position information data in step S42 passes the position information data to the staying number of people determination unit 8E, and the staying number of people determination unit 8E determines whether or not a person is present (step S43). Here, the staying number of people determination unit 8E receives the position information data, and at the same time, refers to the facility attribute information data table (FIG. 5) held in the master information DB 8H to acquire the current reservation information for the seat with the seat number 8Hc "001". The staying number of people determination unit 8E then performs a process of determining whether or not a person is present by collating the data received from the reservation number of people counting unit 8F.

[0055] Thereafter, after the seat number 8Hc “001” in building 4 is actually empty during the usage time, the “first receiving terminal” of receiving terminal 10Aa transmits the currently detected location information to location information GW10 (step S44). The position information GW 10, which has received the current position information data in step S44, transmits the position information data detected in step S44 to the number of people comparing unit 8C in the control command server 8 (step S45).

[0056] The number of people comparing unit 8C, which has received the position information data in step S45, determines whether or not a person is present (step S46). That is, the number of people comparing unit 8C refers to the facility attribute information data table (FIG. 5) stored in the master information DB 8H of the information managing unit 8Y, and acquires the current reservation information for the seat with the seat number 8Hc "001". The number of people comparing unit 8C then collates the determination by the staying number of people determining unit 8E with the data received from the reserved number of people counting unit 8F to determine whether or not a person is present.

[0057] From the result of the determination in step S46, the control command server 8 determines whether the seat determined to be unoccupied is a seat during the usage time period (step S47). Furthermore, from the results of the determinations in steps S46 and S47, the control command server 8 determines whether the absence of a person has continued for 5 minutes or more (step S48). Here, when it is determined that the absence of a person has continued for 5 minutes or more (step S49), the control command server 8 selects the building facility corresponding to the relevant seat as a control target (step S50).

[0058] That is, the control command server 8 refers to the equipment attribute information data table (FIG. 5) in the master information DB 8H to determine the control target. For example, when the position information sensor 8Hd that matches the seat number 8Hc "001" is the "first receiving terminal" and the control device 8He is the "first air conditioning" and the "first lighting", the control command server 8 selects the "first air conditioning" and the "first lighting" as the building equipment to be operated.

[0059] Then, the device control unit 8D of the control unit 8X generates a control command for suppression operation for preliminary operation for the "first air conditioning" (step S51). The control command for the suppressed operation generated in step S51 is transmitted from the equipment control unit 8D via the information transmission unit 8A to the air conditioning control GW 12 (step S52). The air conditioning control GW12 that has received the control command converts the received control command into transmission data for controlling the device of the "first air conditioning" and transmits it to the "first air conditioning" (step S53).

[0060] The air conditioner serving as the "first air conditioner" starts suppression operation in accordance with the control command sent in step S53 (step S54). Then, the air conditioner serving as the "first air conditioner" replies to the air conditioner control GW12 that it has responded normally by starting suppression operation (step S55). Having received this response, the air conditioner control GW12 replies to the device control unit 8D of the control command server 8 with the control result for the "first air conditioner" control command (step S56).

[0061] In Fig. 8, as in Fig. 7, the process is explained using the "first air conditioning" which is an air conditioning equipment as an example, but the "first lighting" which is a different control target is controlled using the same process flow. Also, suppression operation when no one is present is performed using the same process flow for other building equipment other than air conditioning equipment and lighting equipment.

[0062] As described above, according to this embodiment, air conditioning equipment and lighting equipment can be controlled in detail for each room or area corresponding to the reserved seat, based on the seat reservation of each user in the building through the seat reservation system 2. In particular, equipment that requires advance operation, such as air conditioning equipment, is operated in detail in advance for each room or area corresponding to the seat to be used, allowing building users to use the building comfortably and optimizing the operating efficiency of the building equipment.

[0063] In addition, if there is no user in the reserved seat or in its vicinity, the equipment in the corresponding room or area will be operated with reduced operation, so that the operating status of the building equipment will be corrected based on actual usage, making it possible to carry out more appropriate operational control of the building equipment.

[0064] [Variations] It should be noted that the embodiment examples described so far have been described in detail in order to explain the present invention in an easily understandable manner, and are not necessarily limited to those having all of the configurations described.

[0065] In addition, the air conditioning / lighting control system 1 shown in FIG. 2 and the control command server 8 shown in FIG. 3 show the schematic configuration required for control, but the air conditioning / lighting control system 1 and the control command server 8 are configured, for example, by implementing a program in a computer device.

[0066] FIG. 9 shows an example of a hardware configuration when the air-conditioning and lighting control system 1 is configured with a computer device. The air conditioning / lighting control system 1 includes a CPU (Central Processing Unit) 1a, a main memory unit 1b, a non-volatile storage 1c, a network interface 1d, an input device 1e, and an output device 1f, all of which are connected to a bus.

[0067] The CPU 1a is an arithmetic processing unit that reads out and executes program code of software that realizes the functions performed by the air-conditioning and lighting control system 1 from the main storage unit 1b or the non-volatile storage 1c. The CPU 1a reads out program codes from the main memory 1b or the non-volatile storage 1c and executes arithmetic processing in the work area of ​​the main memory 1b, thereby configuring various processing function units in the main memory 1b. For example, the main memory 1b is configured with an information management unit 1X and an information transmission unit 1Y shown in FIG. 2.

[0068] The non-volatile storage 1c may be, for example, a large-capacity information storage medium such as a hard disk drive (HDD), a solid state drive (SSD), a memory card, etc. The non-volatile storage 1c stores software that realizes the functions of the air-conditioning and lighting control system 1, data obtained by executing the program, and information serving as the databases 1A and 1B.

[0069] The network interface 1d is, for example, a network interface card (NIC) and is used to transmit and receive data to and from other devices. The input device 1e is composed of devices such as a keyboard connected to a computer device that functions as the air-conditioning and lighting control system 1, and input operations are performed by an administrator of the air-conditioning and lighting control system 1. The output device 1f performs output processing such as displaying the processing results.

[0070] Although FIG. 9 shows the configuration of the air conditioning and lighting control system 1, when the control command server 8 is configured as a computer device, the hardware configuration is the same. Further, some or all of the functions performed by the air conditioning and lighting control system 1 and the control command server 8 may be realized by hardware such as a field programmable gate array (FPGA) or an application specific integrated circuit (ASIC).

[0071] Furthermore, in the above-described embodiment, the air conditioning equipment, lighting equipment, and elevator equipment have been described as building facilities, but other building facilities may also be controlled in a similar manner. The example in FIG. 10 is an application to a robot placed in a building as building equipment. That is, the building facility includes a robot control gateway 15, and the robot control gateway 15 communicates with a security robot control unit 15A, a cleaning robot control unit 15B, and a guide robot control unit 15C. Then, in response to a command from the control command server 8, the robot control gateway 15 issues operating state commands to the robot control units 15A, 15B, and 15C based on the seat reservation information. For example, the control command server 8 instructs the security robot control unit 15A and the cleaning robot control unit 15B to use robots to guard and clean rooms that are no longer occupied, based on the reservation status and the occupancy status of each seat. Alternatively, if there is a room in which the occupancy status is detected to be different from the reservation status, the security robot control unit 15A is instructed to have a robot guard the corresponding room. Furthermore, the control command server 8 instructs the guide robot control unit 15C to provide guidance immediately before the reservation start time. In this way, the robot may be controlled based on the reservation status and the occupancy status of each seat.

[0072] 1 to 3, only control lines and information lines that are considered necessary for explanation are shown, and not all control lines and information lines in the product are shown. In reality, it can be considered that almost all components are connected to each other.

[0073] Furthermore, when the air conditioning / lighting control system 1 and the control command server 8 are configured as a computer device, the programs that realize the air conditioning / lighting control system 1 and the control command server 8 may be stored in a non-volatile storage or memory within the computer device, or may be stored in an external memory, an IC card, an SD card, an optical disk, or other recording medium and transferred for use.
