Description

[Technical field]

[0001] The present disclosure relates to a facility management system and a facility management method. [Background technology]

[0002] JP 2019-92049 A (Patent Document 1) discloses a facility management system that is configured so that staff (cleaners, security guards, facility maintenance staff, etc.) who move around the facility carry sensors that measure the situation within the facility and use the measurement data from the sensors to grasp the situation within the facility.

[0003] In this facility management system, the sensor measures the temperature, humidity, etc. around the current location, generates sensor information including the measurement data, the measurement date and time, and the sensor's location information, and transmits it to the management device. The management device identifies the position of the sensor on the facility's drawing data at the measurement date and time of the sensor data from the location information included in the sensor information. The management device then superimposes a symbol image corresponding to the sensor that detected the abnormality on the sensor's location on the facility's drawing data to generate a facility management drawing, and displays the facility management drawing on a display.

[0004] The management device also periodically collects sensor information and compiles multiple pieces of sensor information of the same type to provide various information about the situation inside the facility. For example, the management device compiles the temperatures measured by each temperature sensor at a certain point in time to generate a temperature distribution (heat map) image inside the facility, and displays the generated temperature distribution image by superimposing it on the drawing data of the facility. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2019-92049 A Summary of the Invention [Problem to be solved by the invention]

[0006] According to the facility management system described in Patent Document 1, it is possible to inform a facility manager of what kind of abnormality has occurred and where in the facility from a facility management drawing. For example, if a symbol image of a temperature sensor is displayed in a certain room, the facility manager can know that the room temperature in that room is abnormal. In addition, the facility manager can grasp the temperature situation in the facility from a temperature distribution image.

[0007] On the other hand, one of the factors that can cause discomfort to users moving along the corridors in a facility is the temperature difference that occurs along the corridor. Even if the temperature in each area along the corridor is normal, if the temperature difference between two areas is large, there is a concern that users moving between the two areas will feel uncomfortable. However, since the facility management drawing does not display a symbol image indicating an abnormal temperature difference, and the temperature distribution image does not contain information on the temperature difference, there is a problem that the facility manager cannot easily grasp from the facility management drawing in which section of the corridor a temperature difference that makes users feel uncomfortable is occurring.

[0008] The present disclosure has been made to solve such problems, and the object of the present disclosure is to provide a facility management system and a facility management method that can easily grasp temperature differences that may cause discomfort to users moving through the corridors within the facility. [Means for solving the problem]

[0009] A facility management system according to one aspect of the present disclosure includes a management device that manages the temperature within a facility, a sensor, an acquisition means, and a transmission means. The sensor moves with the mobile object along a passageway along which facility users move and measures the temperature within the facility. The acquisition means acquires location information of the sensor. The transmission means transmits the measurement data and location information of the sensor to the management device. The management device receives the measurement data and location information from the transmission means. The management device calculates the temperature difference between adjacent areas on the passageway from the received measurement data and location information. The management device generates a facility management drawing that represents the temperature environment within the facility by superimposing a first image, in which an arrow indicates the direction of movement in which a temperature difference of a predetermined threshold or more occurs, on the passageway in the drawing data of the facility.

[0010] A facility management method according to one aspect of the present disclosure is a facility management method for managing a temperature inside a facility. The facility management method includes a step of acquiring measurement data of a sensor that moves with a mobile object along a passageway where facility users move and measures the temperature inside the facility, a step of acquiring position information of the sensor, a step of calculating a temperature difference between adjacent areas on each area on the passageway from the acquired measurement data and the position information, and a step of superimposing a first image, in which an arrow indicates a movement direction in which a temperature difference equal to or greater than a predetermined threshold occurs, on the passageway in the drawing data of the facility, to generate a facility management drawing showing the temperature environment inside the facility. Effect of the Invention

[0011] According to the present disclosure, temperature differences that may cause discomfort to users moving through the corridors of a facility can be easily understood from a facility management drawing. [Brief description of the drawings]

[0013] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. In the drawings, the same or corresponding parts are designated by the same reference characters and the description thereof will not be repeated.

[0014] <Facility management system configuration> 1 is an overall configuration diagram of a facility management system according to an embodiment of the present disclosure. Facility management system 100 according to the present embodiment is a system for managing the temperature within facility 1 used by many people, such as an office building or a shopping mall. In the following, a shopping mall will be described as an example of facility 1 to which facility management system 100 according to the present embodiment is applied.

[0015] 1 shows an elevation view of a certain floor of a facility 1. Each floor is provided with a passageway along which users 2, such as shoppers, can move. Additionally, the facility 1 is equipped with air conditioning equipment 40 to maintain a temperature environment on each floor that is comfortable for users 2. The air conditioning equipment 40 has multiple indoor units arranged at appropriate distances on each floor.

[0016] As shown in FIG. 1, a facility management system 100 includes a terminal device 10, a server 20, a controller 30, an air conditioning facility 40, a sensor 50, and a plurality of wireless communication devices 60-1, 60-2, . . .

[0017] Staff members 3 are employed in the facility 1. The staff members 3 are, for example, cleaners, security guards, facility maintenance personnel, etc. The staff members 3 carry terminal devices 10 while working. The terminal devices 10 are portable computers such as smartphones, PDAs (Personal Digital Assistants), tablet terminals, and notebook computers.

[0018] The staff member 3 further carries a sensor 50. The sensor 50 is a sensor that measures the situation within the facility 1. The sensor 50 includes a sensor that measures the temperature within the facility 1. The sensor 50 may further include sensors that measure humidity, carbon dioxide concentration, illuminance, sound volume, and the like within the facility 1. By having the staff member 3 carry the sensor 50, when the staff member 3 moves along the corridors within the facility 1, the sensor 50 also moves along the corridors together with the staff member 3. The staff member 3 corresponds to one embodiment of a "mobile object." The mobile object is not limited to the staff member 3, and may be, for example, a self-propelled robot that moves autonomously within the facility 1.

[0019] The sensor 50 and the terminal device 10 communicate with each other by a short-distance wireless communication method. For the short-distance wireless communication method, a communication method conforming to the BLE (Bluetooth Low Energy, "Bluetooth" is a registered trademark) standard or a communication method conforming to the NFC (Near Field Communication) standard can be used. For example, the sensor 50 is equipped with a transmitter conforming to the BLE standard and transmits a signal including data measured by the sensor 50 (measurement data). The terminal device 10 receives the signal transmitted by the sensor 50. The terminal device 10 has a clock means for obtaining the measurement date and time of the received measurement data.

[0020] A plurality of wireless communication devices 60-1, 60-2... (hereinafter sometimes collectively referred to as "wireless communication device 60") are installed at appropriate distances, for example, on a ceiling 65 of each floor. Specifically, the corridor of each floor is divided into a plurality of areas, and a plurality of wireless communication devices 60 are installed corresponding to each of the plurality of areas.

[0021] Each wireless communication device 60 and the terminal device 10 communicate with each other by a short-distance wireless communication method such as a communication method conforming to the BLE standard or a communication method conforming to the NFC standard. For example, the wireless communication device 60 is a beacon conforming to the BLE standard and is configured to transmit a signal within a radius of several meters. The signal transmitted by the wireless communication device 60 includes an ID for identifying the wireless communication device itself.

[0022] The terminal device 10 acquires signals from multiple wireless communication devices 60 in the vicinity. The closer a wireless communication device 60 is to the terminal device 10, the stronger the signal strength received from that wireless communication device 60. The terminal device 10 determines the relative position between each wireless communication device 60 and the terminal device 10 based on the difference in reception strength from each wireless communication device 60. Then, the terminal device 10 identifies the current position of the terminal device 10 from the relative positions between each wireless communication device 60 and the terminal device 10 and the positions of each wireless communication device 60 within the facility 1. The current position of the terminal device 10 corresponds to the current position of the sensor 50. That is, the terminal device 10 acquires position information of the sensor 50 from the reception strength from each wireless communication device 60.

[0023] In this embodiment, a configuration has been described in which location information of the sensor 50 is obtained from the reception strength from each wireless communication device 60, but the location information of the sensor 50 may also be obtained using a GPS function installed in the terminal device 10.

[0024] The server 20 manages the temperature within the facility 1. The server 20 and the terminal device 10 are connected to be able to communicate with each other via a network such as the Internet. The terminal device 10 generates sensor information including measurement data of the sensor 50, the measurement date and time of the measurement data, and location information of the sensor 50, and transmits the generated sensor information to the server 20. The server 20 uses the sensor information received from the terminal device 10 to generate a facility management drawing showing the temperature environment within the facility 1. The server 20 has a display unit 27, and displays the generated facility management drawing on the display unit 27.

[0025] When the server 20 receives a user operation from a user such as a facility manager specifying operating conditions such as the set temperature of the air conditioning equipment 40, the server 20 generates a control signal for controlling the air conditioning equipment 40 based on the received user operation, and transmits the generated control signal to the controller 30. The server 20 will be described in detail later.

[0026] In the present embodiment, the terminal device 10 and the sensor 50 are carried by the staff member 3, and the terminal device 10 acquires the measurement data of the sensor 50 from the sensor 50, generates sensor information, and transmits it to the server 20. However, the terminal device 10 and the sensor 50 may be integrally formed. As long as the staff member 3 is allowed to carry the sensor 50 and is configured to transmit to the server 20 the measurement data acquired by the sensor 50, the measurement date and time of the measurement data, and the sensor information including the location information of the sensor 50, there is no need to be particularly limited with regard to the configuration within the facility 1.

[0027] The controller 30 is communicatively connected to the air conditioning equipment 40. Although not shown, the air conditioning equipment 40 has a plurality of indoor units arranged at an appropriate distance on each floor. The controller 30 and the server 20 are communicatively connected via a network. The controller 30 receives a control signal for controlling the operation of the air conditioning equipment 40 from the server 20. The control signal includes a temperature change command for changing the set temperature of each indoor unit. The controller 30 controls the operation of the air conditioning equipment 40 in accordance with the control signal provided from the server 20. Specifically, the controller 30 changes the set temperature of each indoor unit in accordance with the temperature change command.

[0043] <Facility Management System Operation> Next, the operation of facility management system 100 according to the present embodiment will be described.

[0044] Fig. 3 is a flowchart showing the procedure of the processing executed by the terminal device 10, the server 20, and the controller 30. In Fig. 3, a series of processing executed by the terminal device 10 is shown on the left, a series of processing executed by the server 20 is shown in the center, and a series of processing executed by the controller 30 is shown on the right. Hereinafter, step is abbreviated as S. The series of processing shown in the flowchart of Fig. 3 is executed at each predetermined control cycle. The processing executed by the terminal device 10, the processing executed by the server 20, and the processing executed by the controller 30 may be configured to be executed at mutually different control cycles.

[0045] (Operation of terminal device 10) In S01, the terminal device 10 receives a signal including measurement data from the sensor 50. The terminal device 10 stores the received measurement data in the storage device 14 in association with the measurement date and time of the measurement data.

[0046] In S02, the terminal device 10 acquires location information of the sensor 50 from the reception strength of the signal received from each wireless communication device 60. The terminal device 10 stores the location information of the sensor 50 in the storage device 14 in association with the measurement data of the sensor 50 and the measurement date and time of the measurement data.

[0047] In S03, the terminal device 10 generates sensor information including the measurement data of the sensor 50, the measurement date and time of the measurement data, and location information of the sensor 50, which are stored in the storage device 14, and transmits the generated sensor information to the server 20.

[0048] (Server 20 operation) In S11, the server 20 determines whether or not sensor information has been received from the terminal device 10. If the sensor information has been received (YES in S11), the server 20 stores the received sensor information in the storage device 24 in S12.

[0049] Fig. 4 is a diagram showing an example of the sensor information. As shown in Fig. 4, the sensor information includes measurement data of the sensor 50, data on the measurement date and time of the measurement data, and location information of the sensor 50. The measurement data of the sensor 50 includes the temperature measurement value by the sensor 50.

[0050] FIG. 4 shows a table created based on sensor information received from the sensor 50 between 13:00 and 14:00 on August 10, 2023 for the 3F floor in the facility 1. For example, the first row of the table in FIG. 4 shows that the temperature near the north entrance 1 on the 3F is 26.5°C at 13:00 on August 10, 2023. The second row of the table shows that the temperature near the east plaza on the 3F is 26.0°C at 13:03 on August 10, 2023.

[0051] FIG. 5 is a diagram showing the movement route of the staff member 3 and a part of the sensor information shown in FIG. 4. FIG. 5 shows floor plan data (plan view) of the 3rd floor in the facility 1. The arrow W in the figure represents the movement route of the staff member 3. In the example of FIG. 5, the staff member 3 moves from the north entrance 1 on the 3rd floor to the east plaza, the north passage, the west passage, the south passage, and the east passage in this order. As the staff member 3 moves, the measurement position of the sensor 50 changes. The sensor 50 measures the temperature at the current position and transmits the measurement data to the terminal device 10 carried by the staff member 3. The numerical value T in the figure indicates the temperature measurement value by the sensor 50. The terminal device 10 generates sensor information including the measurement data of the sensor 50, the measurement date and time of the measurement data, and the position information of the sensor 50 for each control period, and transmits the sensor information to the server 20.

[0052] Returning to FIG. 3, in S13, the server 20 sets an abnormal range of temperature within the facility 1 and a temperature change direction representing the temperature difference occurring along the corridor, as shown on the facility management drawing, according to the season to which the measurement date and time of the measurement data belongs.

[0053] The abnormal temperature range is set in consideration of the temperature in the facility 1 at which the user 2 can be comfortable. Generally, the optimum temperature for a user to be comfortable is -10°C of body temperature. The comfortable temperature changes according to the season. In some cases, the comfortable temperature is 25 to 28°C in summer and 18 to 22°C in winter. Therefore, in S13, if the measurement date and time of the measurement data belongs to summer, the abnormal temperature range in the facility 1 is set to 27°C or higher. If the measurement date and time of the measurement data belongs to winter, the abnormal temperature range in the facility 1 is set to 19°C or lower. The facility manager can use the input unit 26 to set the abnormal temperature range for each season in advance.

[0054] The temperature difference occurring on the passage means the temperature difference between any area of ​​the passage and the area adjacent to that area. The temperature change direction representing the temperature difference occurring on the passage corresponds to the movement direction in which this temperature difference occurs. The temperature change direction includes the movement direction in which the temperature rises as the user 2 moves (hereinafter also referred to as the "temperature rise direction"), and the movement direction in which the temperature falls as the user 2 moves (hereinafter also referred to as the "temperature fall direction").

[0055] The server 20 sets the temperature change direction, which represents the temperature difference occurring on the passageway, according to the season to which the measurement date and time of the measurement data belongs, taking into consideration whether the temperature difference occurring on the passageway may cause discomfort to the user 2 moving along the passageway. In one aspect, when the measurement date and time of the measurement data belongs to the summer season, the server 20 sets the temperature change direction, which represents the temperature difference occurring on the passageway, to the temperature increasing direction. This is because, in the summer season, moving from a low temperature area to a high temperature area is more likely to cause discomfort to the user 2 than moving from a high temperature area to a low temperature area.

[0056] On the other hand, if the measurement date and time of the measurement data belongs to winter, the server 20 sets the temperature change direction, which represents the temperature difference occurring along the passage, to a temperature decreasing direction. This is because, in winter, moving from a high temperature area to a low temperature area is more likely to cause discomfort to the user 2 than moving from a low temperature area to a high temperature area.

[0057] In S14, the server 20 detects, from among the multiple areas of the passage, an area in which the temperature falls within the abnormal range (hereinafter also referred to as an "abnormal temperature area") based on the sensor information stored in the storage device 24. In S14, the server 20 determines for each area whether the temperature falls within the abnormal range set in S13. Specifically, when the measurement date and time of the measurement data falls in summer, the server 20 detects an area in which the temperature is 27°C or higher. When the measurement date and time of the measurement data falls in winter, the server 20 detects an area in which the temperature is 19°C or lower. FIG. 5 shows an abnormal temperature area R1 when the measurement date and time falls in summer.

[0058] Next, in S15, the server 20 calculates the temperature difference occurring in the passage based on the sensor information stored in the storage device 24. In S15, the server 20 calculates the temperature difference between each area of ​​the passage and an adjacent area. Specifically, for each row of the table in Fig. 4, the server 20 calculates the difference (temperature difference) between the measured temperature value in that row and the measured temperature value in the row adjacent to that row in the vertical direction.

[0059] In S16, the server 20 detects an area in the passageway where the temperature difference is equal to or greater than a predetermined threshold (hereinafter, also referred to as an "abnormal temperature difference area"). In this embodiment, the threshold is 2.0°C. The server 20 detects an area where the temperature difference with an adjacent area is equal to or greater than 2.0°C as an abnormal temperature difference area. FIG. 5 shows an abnormal temperature difference area R2.

[0060] In S17, the server 20 uses the detection results in S14 and S16 to generate a facility management diagram showing the temperature environment within the facility 1. In S17, the facility management diagram is generated by superimposing an image showing the temperature abnormal area R1 and the temperature difference abnormal area R2 with arrows on the passage of the diagram data of the facility 1. The server 20 displays the generated facility management diagram on the display unit 27.

[0061] Fig. 6 is a diagram showing a first example of a facility management drawing. The facility management drawing shown in Fig. 6 was generated from the sensor information shown in Fig. 4, and is a facility management drawing for a case where the measurement date and time of the measurement data of the sensor 50 belongs to the summer season.

[0062] As shown in FIG. 6, the abnormal temperature area R1 shown in FIG. 5 is represented by an arrow image A1 on the facility management drawing. The abnormal temperature area R1 is an area where the temperature falls within the abnormal range (27° C. or higher). The direction of the arrow image A1 represents the direction of movement toward the abnormal temperature area R1. The facility management drawing shows an image T1 indicating the measurement data of the sensor 50 alongside the arrow image A1. The arrow image A1 represents the direction in which user 2 should move down the corridor to enter the abnormal temperature area R1. The arrow image A1 corresponds to one example of the "second image."

[0063] Furthermore, the facility management drawing indicates the temperature difference abnormal area R2 shown in FIG. 5 with an arrow image A2. The temperature difference abnormal area R2 is an area where the temperature difference with an adjacent area is equal to or greater than a threshold value (2.0°C). The direction of the arrow image A2 is set based on the temperature change direction set in S13. Specifically, if the measurement date and time of the measurement data belongs to the summer season, the temperature change direction representing the temperature difference accompanying the movement of the user 2 is set to the temperature rising direction. Therefore, the server 20 sets the direction of the arrow image A2 to the temperature rising direction. The temperature rising direction is the direction in which the temperature rises accompanying the movement of the user 2.

[0064] On the facility management drawing, an arrow image A2 is shown in the area corresponding to abnormal temperature difference area R2, pointing in the direction of temperature rise. Arrow image A2 indicates in which direction moving down the corridor will cause a temperature change (temperature rise) of more than the threshold (2.0°C). Along with arrow image A2, the facility management drawing also shows image T2 indicating the temperature difference. Image T2 indicates that moving in the direction of the arrow will result in a temperature rise of +2.0°C. Arrow image A2 corresponds to one example of the "first image."

[0065] 3, in S18, the server 20 determines whether or not the input unit 26 has accepted a user operation specifying an operating condition such as a set temperature of the air conditioning equipment 40. If the input unit 26 has accepted a user operation (YES in S18), the server 20 in S19 generates a control signal for controlling the air conditioning equipment 40 based on the accepted user operation and transmits the generated control signal to the controller 30.

[0066] (Operation of controller 30) In S21, the controller 30 determines whether or not a control signal for controlling the operation of the air conditioning equipment 40 has been received from the server 20. The control signal includes a temperature change command for changing the set temperature of each indoor unit. If the controller 30 has received a control signal from the server 20 (YES in S21), in S22 the controller 30 controls the operation of the air conditioning equipment 40 in accordance with the control signal. In S22, the controller 30 changes the set temperature of each indoor unit in accordance with the temperature change command.

[0067] (Example of facility management drawing) In the above-described embodiment, a facility management drawing (FIG. 6) is illustrated in which the measurement date and time of the measurement data of the sensor 50 falls in the summer season. However, even if the measurement date and time of the measurement data falls in the winter season, a facility management drawing can be generated according to the procedure shown in FIG. 3.

[0068] FIG. 7 is a diagram showing the movement route of the staff member 3 and a part of the sensor information. FIG. 7 shows floor plan data (plan view) of the 3rd floor in the facility 1. The arrow W in the figure indicates the movement route of the staff member 3. As in the example of FIG. 5, in the example of FIG. 7, the staff member 3 moves from the north entrance 1 on the 3rd floor to the east plaza, the north passage, the west passage, the south passage, and the east passage in this order. As the staff member 3 moves, the measurement position of the sensor 50 changes. The numerical value T in the figure indicates the measured temperature value at the current position of the sensor 50. The terminal device 10 generates sensor information including the measurement data of the sensor 50, the measurement date and time of the measurement data, and the position information of the sensor 50 for each control period, and transmits the sensor information to the server 20.

[0069] The server 20 detects an abnormal temperature area in a passageway within the facility 1 based on the sensor information stored in the storage device 24. The server 20 detects an area where the temperature is below 19° C. Fig. 7 shows an abnormal temperature area R3 when the measurement date and time falls in the winter season.

[0070] Furthermore, the server 20 calculates the temperature difference occurring along the passage based on the sensor information stored in the storage device 24. The server 20 then detects an area where the temperature difference between the adjacent area and the area is 2.0°C or more as an abnormal temperature difference area. An abnormal temperature difference area R4 is shown in FIG. 7.

[0071] Next, the server 20 generates a facility management drawing by superimposing an image in which the temperature abnormal area R3 and the temperature difference abnormal area R4 are represented by arrows on the passage of the drawing data of the facility 1. The server 20 displays the generated facility management drawing on the display unit 27.

[0072] FIG. 8 is a diagram showing a second example of a facility management drawing. The facility management drawing shown in FIG. 8 is a facility management drawing in the case where the measurement date and time of the measurement data of the sensor 50 belongs to winter. As shown in FIG. 8, in the facility management drawing, the abnormal temperature area R3 shown in FIG. 7 is represented by an arrow image A1. The abnormal temperature area R3 is an area where the temperature belongs to the abnormal range (19°C or less). The direction of the arrow image A1 represents the movement direction toward the abnormal temperature area R1. The facility management drawing shows an image T1 showing the measurement data of the sensor 50 together with the arrow image A1. The arrow image A1 represents in which direction the user 2 should move down the passage to enter the abnormal temperature area R1.

[0073] Furthermore, the facility management drawing indicates the abnormal temperature difference area R4 shown in Fig. 7 with an arrow image A2. If the measurement date and time of the measurement data belongs to winter, the temperature change direction indicating the temperature difference as the user 2 moves is set to a temperature decreasing direction. Therefore, the server 20 sets the direction of the arrow image A2 to a temperature decreasing direction. The temperature decreasing direction is the direction in which the temperature decreases as the user 2 moves.

[0074] On the facility management drawing, an arrow image A2 is shown in the area corresponding to abnormal temperature difference area R4, pointing in the direction of temperature decrease. Arrow image A2 indicates in which direction moving down the corridor will cause a temperature change (temperature decrease) of more than the threshold value (2.0°C). Along with arrow image A2, the facility management drawing also shows image T2 indicating the temperature difference. Image T2 indicates that moving in the direction of the arrow will result in a temperature decrease of -2.0°C.

[0075] As described above, according to the facility management system 100 of this embodiment, the moving direction in which a temperature difference equal to or greater than a threshold occurs is represented on the aisle in the drawing data of the facility 1 by using an arrow image A2. Therefore, the facility manager can easily understand from the facility management drawing which area of ​​the aisle is generating a temperature difference that makes users feel uncomfortable. This allows the facility manager to efficiently control the air conditioning equipment 40 to reduce the temperature difference generated on the aisle. As a result, the discomfort of the users 2 moving through the facility 1 can be reduced.

[0076] Furthermore, facility management system 100 according to this embodiment switches the direction of movement indicated by the arrow between a direction of increasing temperature and a direction of decreasing temperature depending on the season to which the measurement date and time of the measurement data of sensor 50 belongs. In this way, the facility manager can easily grasp the direction of movement that causes temperature differences that make users feel uncomfortable for each season.

[0077] Furthermore, in facility management system 100 according to this embodiment, the direction of movement toward the temperature abnormality area is shown by using an arrow image A1 on the passage in the drawing data of facility 1. This allows the facility manager to know in which direction user 2 should move along the passage to enter the temperature abnormality area. Furthermore, by changing the temperature abnormality range according to the measurement date and time of the measurement data of sensor 50, the facility manager can know the direction of movement that may cause discomfort to users for each season.
