Embodiment 1.
FIG. 1 is a configuration diagram of an elevator system 1 according to the first embodiment.

FIG. 1 shows an example of the configuration of the building system 2 including the elevator system 1. The building system 2 is applied to a building having a plurality of floors. The building to which the building system 2 is applied has a free address area. The free address area is an area that spans multiple floors. The free address area is an area in which a user who uses the area uses an vacant seat without having a specific fixed seat. The free address area is, for example, the area of the office where the user works. Alternatively, the free address area may be, for example, an area such as a library or a museum where a user browses materials such as books. In this example, the user of the free address area can use any of the floors of the plurality of floors provided with the free address area.

The building system 2 includes a monitoring device 3 and a management device 4. The monitoring device 3 is a device that monitors the state of the building. The state of the building includes, for example, the floor information of each floor and the power demand of the building. The floor information includes, for example, floor temperature information, availability information, energy consumption information, and the like. The floor temperature of a floor is, for example, the air temperature on the floor. In the floor where the free address area is provided, the floor temperature may be, for example, the air temperature in the free address area. Floor availability is monitored for floors where free address areas are provided. The vacancy status of a floor is, for example, the number of vacant seats or the vacancy rate on the floor. The amount of energy used on a floor is the amount of energy used on that floor. The energy consumption of a floor is, for example, the amount of energy used for air conditioning of the floor. The management device 4 is a device that manages the environment of the building. The management device 4 manages, for example, the operation of an air conditioner (not shown) provided in a building.

In the building, a hoistway (not shown) will be provided. The hoistway is a vertically long space that spans multiple floors. A landing 5 is provided on each floor. A landing operation panel 6 and a first infrared sensor 7 are provided at the landing 5 on each floor.

The landing operation panel 6 is a device that accepts the operation of the user of the elevator system 1. The landing operation panel 6 accepts user operations using, for example, a touch panel. The operation accepted by the landing operation panel 6 is, for example, an operation of calling the landing. The landing call operation is an operation in which the user calls the car 8 from the landing 5. The landing operation panel 6 accepts the operation of calling the landing of the user who moves to the area of the free address.

The first infrared sensor 7 is a device that measures the temperature of the user of the elevator system 1 at the landing 5 by infrared rays. The user of the elevator system 1 is, for example, a person. The first infrared sensor 7 measures the body temperature of a person at the landing 5 as the temperature of a user who is a person. The body temperature measured here is the temperature of the body surface. The elevator system 1 may be used by a non-human moving body such as a robot. At this time, the first infrared sensor 7 measures the surface temperature of the moving body at the landing 5 as the temperature of the user.

The elevator system 1 includes a plurality of baskets 8, a plurality of control panels 9, and a group management device 10.

Each car 8 is provided on the hoistway. Each car 8 is a device for transporting a user or the like between a plurality of floors by traveling in a vertical direction on a hoistway. Each car 8 includes a car operation panel 11 and a second infrared sensor 12. The car operation panel 11 is a device that accepts the operation of the user of the elevator system 1. The car operation panel 11 accepts user operations by, for example, a plurality of buttons. The operation accepted by the car operation panel 11 is, for example, a car calling operation. The car calling operation is an operation in which the user specifies the destination floor from the car 8. The second infrared sensor 12 is a device that measures the temperature of the user of the elevator system 1 in the car 8 by infrared rays.

Each control panel 9 corresponds to any of the baskets 8. Each control panel 9 is a part that controls the operation of the corresponding car 8. The operation of the car 8 includes, for example, running of the car 8.

The group management device 10 includes a floor information acquisition unit 13, a call information acquisition unit 14, a user information acquisition unit 15, and a call processing unit 16.

The floor information acquisition unit 13 is a part that acquires floor information of each floor. The floor information acquisition unit 13 is connected to the monitoring device 3 so that, for example, the floor information can be acquired.

The call information acquisition unit 14 is a part that acquires user call information. The call information acquisition unit 14 acquires information on the landing call received by the landing operation panel 6. The call information acquisition unit 14 acquires information on the car call received by the car operation panel 11. The call information acquisition unit 14 outputs the acquired call information to the call processing unit 16.

The user information acquisition unit 15 is a part that acquires user information of the elevator system 1. The user information acquisition unit 15 acquires information such as a measured value of the user's temperature measured by the first infrared sensor 7. The user information acquisition unit 15 acquires information such as a measured value of the user's temperature measured by the second infrared sensor 12. The user information acquisition unit 15 is equipped with a function of determining the presence or absence of an abnormality based on the acquired information. When the user information acquisition unit 15 determines that there is an abnormality, the user information acquisition unit 15 issues a report to the monitoring device 3. The notification to the monitoring device 3 may be performed through the floor information acquisition unit 13.

The call processing unit 16 is a part that processes a user's call. The call processing in the call processing unit 16 includes, for example, selection of the destination floor of the call and allocation of the call to any one of the plurality of cars 8.

The destination floors selected by the call processing unit 16 are selected by the floor information of each floor acquired by the floor information acquisition unit 13, the call information acquired by the call information acquisition unit 14, and the user information acquisition unit 15. It is performed based on the acquired user information. The destination floor is selected, for example, based on the user's comfortable temperature. Here, the comfortable temperature of the user is calculated by, for example, the call processing unit 16 based on the temperature of the user acquired by the user information acquisition unit 15.

The call processing unit 16 is connected to each control panel 9 so that the information of the call can be output to the control panel 9 corresponding to the car 8 to which the call is assigned. The information on the call includes information on the selected destination floor.

The call processing unit 16 operates based on a switchable operation mode. The operation mode of the call processing unit 16 is switched between a plurality of modes including a normal mode and an energy saving mode. During the normal operation of the elevator system 1, the operation mode of the call processing unit 16 is set to the normal mode. The operation mode of the call processing unit 16 is switched based on, for example, a mode switching signal input from the monitoring device 3. The mode switching signal may be input through the floor information acquisition unit 13.

In this example, the monitoring device 3 outputs a mode switching signal based on the power demand of the building as follows, for example. The monitoring device 3 estimates the future power demand based on the power demand of the building up to now. The monitoring device 3 outputs a mode switching signal for switching to the energy saving mode when the estimated value of the future power demand exceeds a preset threshold value.

Next, the comfortable temperature used for selecting the destination floor will be described with reference to FIG.
FIG. 2 is a diagram showing an example of a comfortable temperature in the elevator system 1 according to the first embodiment.
The horizontal axis of FIG. 2 represents the temperature of the user. The vertical axis of FIG. 2 represents the comfortable temperature.

The comfortable temperature is the temperature included in the comfortable temperature range. The comfortable temperature range is the temperature range between the lower limit comfortable temperature and the upper limit comfortable temperature. The comfortable temperature range includes the central comfortable temperature. The central comfortable temperature is an intermediate temperature between the lower limit comfortable temperature and the upper limit comfortable temperature. The central comfortable temperature is an example of a comfortable temperature.

The lower limit comfortable temperature is calculated by a monotonous non-increasing relationship with respect to the user's temperature. Here, the monotonically non-increasing relationship may be, for example, a relationship by a step function including one or more discontinuities, a relationship by a monotonically decreasing function, or a relationship by a function combining these. A monotonically decreasing function is, for example, a linear function with respect to the user's temperature, a piecewise polynomial or rational function with respect to the user's temperature, a logarithmic function with a monotonically decreasing gradient with respect to the user's temperature, or a gradient with respect to the user's temperature. Includes monotonically increasing exponential functions and the like. The lower limit comfort temperature is calculated, for example, by a monotonically decreasing function with respect to the user's temperature. In this example, the lower limit comfort temperature is calculated as a linear function with respect to the user's temperature.

The upper limit comfortable temperature is calculated by a monotonous non-increasing relationship with respect to the user's temperature. Here, the monotonically non-increasing relationship may be, for example, a relationship by a step function including one or more discontinuities, a relationship by a monotonically decreasing function, or a relationship by a function combining these. A monotonically decreasing function is, for example, a linear function with respect to the user's temperature, a piecewise polynomial or rational function with respect to the user's temperature, a logarithmic function with a monotonically decreasing gradient with respect to the user's temperature, or a gradient with respect to the user's temperature. Includes monotonically increasing exponential functions and the like. The upper limit comfortable temperature is calculated by, for example, a monotonically decreasing function with respect to the user's temperature. In this example, the upper limit temperature is calculated as a linear function with respect to the user's temperature.

The upper limit comfortable temperature is a temperature higher than the lower limit comfortable temperature. In this example, the rate of change of the upper limit comfortable temperature with respect to the user's temperature is equal to the rate of change of the lower limit comfortable temperature with respect to the user's temperature.

The central comfortable temperature is calculated by a monotonous non-increasing relationship with respect to the user's temperature. Here, the monotonically non-increasing relationship may be, for example, a relationship by a step function including one or more discontinuities, a relationship by a monotonically decreasing function, or a relationship by a function combining these. A monotonically decreasing function is, for example, a linear function with respect to the user's temperature, a piecewise polynomial or rational function with respect to the user's temperature, a logarithmic function with a monotonically decreasing gradient with respect to the user's temperature, or a gradient with respect to the user's temperature. Includes monotonically increasing exponential functions and the like. The central comfort temperature is calculated, for example, by a monotonically decreasing function with respect to the user's temperature. In this example, the central comfort temperature is calculated as a linear function with respect to the user's temperature. The central comfortable temperature is, for example, the arithmetic mean temperature of the lower limit comfortable temperature and the upper limit comfortable temperature. In this example, the rate of change of the central comfortable temperature with respect to the user's temperature is equal to the rate of change of the lower limit comfortable temperature and the rate of change of the upper limit comfortable temperature with respect to the user's temperature.

For example, when the body temperature of a human user is 36.0 ° C, the lower limit comfortable temperature is set to 23.0 ° C. The upper limit comfortable temperature is set to 25.0 ° C. The central comfortable temperature is set to 24.0 ° C.

Subsequently, the function of the elevator system 1 will be described with reference to FIGS. 3 to 5.
3 and 5 are diagrams showing an example of selection of a destination floor by the call processing unit 16 according to the first embodiment.
FIG. 4 is a diagram showing an example of determination by the user information acquisition unit 15 according to the first embodiment.

FIG. 3 shows an example of selecting the destination floor in the normal mode. In this example, the building has 20 floors from the 1st floor to the 20th floor. The free address area covers 19 floors from the 2nd floor to the 20th floor.

In FIG. 3, the floor temperature of each floor is shown. In FIG. 3, the vacancy rate is shown as the vacancy status of each floor. In this example, the user is a person. The user's body temperature is 36.0 ° C. The user moves from the platform 5 on the first floor, which is the departure floor, to the area of the free address.

The first infrared sensor 7 measures the temperature of the user at the landing 5 on the first floor, which is the departure floor. The user information acquisition unit 15 acquires the measured value of the temperature of the user from the first infrared sensor 7. The user information acquisition unit 15 outputs the acquired information to the call processing unit 16.

The floor information acquisition unit 13 acquires the floor information of each floor from the monitoring device 3. Here, the floor information acquired by the floor information acquisition unit 13 in the normal mode includes at least information on the floor temperature. In the example shown in FIG. 3, the floor information acquired by the floor information acquisition unit 13 includes information on the floor temperature and information on the vacancy rate. The floor information acquisition unit 13 outputs the acquired floor information to the call processing unit 16.

The user performs the operation of calling the landing on the landing operation panel 6 on the first floor, for example, as follows.

The landing operation panel 6 displays, for example, one button corresponding to the entire free address area on the touch panel. In this example, the landing operation panel 6 displays one button corresponding to the range from the second floor to the 20th floor. The user registers a landing call to the floor in the range where the free address area is provided by operating the button.

Alternatively, the landing operation panel 6 may display, for example, a plurality of buttons corresponding to each of the plurality of floors provided with the free address area on the touch panel. In this example, the landing operation panel 6 displays 19 buttons corresponding to each of the floors from the second floor to the 20th floor. The user registers a landing call to the floor range where the free address area is provided by operating any of the 19 buttons. In this example, no matter which of the 19 buttons the user operates, a landing call to the same range is registered.

The call information acquisition unit 14 acquires information on the user's landing call from the landing operation panel 6. The call information acquisition unit 14 outputs the acquired information to the call processing unit 16.

The call processing unit 16 receives information on the landing call that moves to the free address area from the landing operation panel 6. At this time, the call processing unit 16 selects the destination floor of the received call, for example, as follows.

The call processing unit 16 calculates the lower limit comfortable temperature and the upper limit comfortable temperature based on the temperature of the user. In this example, the call processing unit 16 calculates the lower limit comfortable temperature as 23.0 ° C. based on the user's body temperature of 36.0 ° C. Further, the call processing unit 16 calculates the upper limit comfortable temperature as 25.0 ° C. based on the user's body temperature of 36.0 ° C. The call processing unit 16 extracts a floor whose floor temperature is within the comfortable temperature range from a plurality of floors provided with a free address area as a candidate for a destination floor. In this example, the floor temperature of the second floor is 23.1 degrees. The floor temperature of the 17th floor is 24.2 ° C. At this time, the call processing unit 16 extracts the second floor and the 17th floor as candidates for the destination floor.

The call processing unit 16 selects a more vacant floor as a destination floor with higher priority based on the availability information from the floors extracted as candidates for the destination floor. In this example, the vacancy rate on the second floor is 0%. The vacancy rate on the 17th floor is 20%. At this time, the call processing unit 16 selects the 17th floor as the destination floor of the user.

Alternatively, the call processing unit 16 may select a floor whose floor temperature is closer to the central comfortable temperature as the destination floor with higher priority. The call processing unit 16 calculates the central comfortable temperature based on the temperature of the user. In this example, the call processing unit 16 calculates the lower limit comfortable temperature as 24.0 ° C. based on the user's body temperature of 36.0 ° C. The call processing unit 16 searches for a floor whose floor temperature is close to the central comfortable temperature from a plurality of floors provided with a free address area. In this example, the floor temperature of the 17th floor is 24.2 ° C, which is the closest to the central comfortable temperature. At this time, the call processing unit 16 selects the 17th floor as the destination floor of the user.

The call processing unit 16 assigns the call for which the destination floor has been selected to one of the plurality of baskets 8. The call processing unit 16 determines whether the temperature of the user measured at the landing 5 is higher than a preset threshold value. The threshold value is set to, for example, a value equal to or higher than the average body temperature of a human user. When it is determined that the temperature of the user is equal to or lower than the threshold value, the call processing unit 16 selects the car 8 to be assigned based on, for example, the operation efficiency of the elevator system 1. On the other hand, when it is determined that the temperature of the user is higher than the threshold value, the call processing unit 16 preferentially allocates the car 8 having fewer users. Here, the number of users in each car 8 is calculated based on the landing call information and the car call information acquired by the call information acquisition unit 14.

The call processing unit 16 outputs the selected destination floor information and the user temperature information to the management device 4. The information input to the management device 4 is used for the operation of the air conditioner. The management device 4 estimates the comfortable temperature of the user who has moved to each floor, for example, based on the input information. The management device 4 operates the air conditioner based on the estimated comfortable temperature.

The call processing unit 16 outputs the information of the call including the information of the selected destination floor to the control panel 9 corresponding to the car 8 to which the call is assigned. The control panel 9 into which the call information is input causes the corresponding car 8 to run on the departure floor of the user in accordance with the call.

The call processing unit 16 outputs the call information including the information of the car 8 to which the call is assigned and the selected destination floor to the landing operation panel 6 provided on the departure floor of the user. The landing operation panel 6 provided on the departure floor of the user notifies the selected destination floor and the assigned car 8. The landing operation panel 6 gives a notification by, for example, displaying on a touch panel or making a voice announcement by a speaker.

Since the user does not have a specific fixed seat, any floor with a free address area can be used in the same way. In this example, the user waits for the car 8 to which the call is assigned at the landing 5 on the departure floor in order to move to the notified destination floor.

After that, the car 8 to which the call is assigned stops on the departure floor. The second infrared sensor 12 measures the temperature of the user who gets in the car 8 stopped on the departure floor. The user information acquisition unit 15 acquires the measured value of the temperature of the user from the second infrared sensor 12. The user information acquisition unit 15 determines the presence or absence of an abnormality based on the acquired user temperature information.

FIG. 4 shows an example of determination by the user information acquisition unit 15.
The horizontal axis of FIG. 4 represents the time. The vertical axis of FIG. 4 represents the measured value of the measured user temperature.

In the user information acquisition unit 15, the person determination temperature range and the abnormal temperature range are set in advance. The person determination temperature range is a temperature range used for determining whether or not the user is a person. The abnormal temperature range is a temperature range used for determining the presence or absence of an abnormality for the user. The human determination temperature range is set to, for example, a temperature range from 34.0 ° C to 40.0 ° C. The lower limit temperature of the abnormal temperature range is set to a temperature higher than, for example, the upper limit temperature of the human judgment temperature range.

The user information acquisition unit 15 makes a determination based on a change in the measured value of the user's temperature with the passage of time. The change in temperature with the passage of time is measured at a preset measurement time t from the start of measurement to the end of measurement. The measurement time t is set to, for example, several seconds.

In this example, the user information acquisition unit 15 determines that the user is a person when the temperature of the user is within the human determination temperature range during the measurement time t. On the other hand, the user information acquisition unit 15 determines that the user is not a person when the temperature of the user is outside the human determination temperature range at a part or all of the time during the measurement time t. do. A non-human user is, for example, a mobile body. When the user information acquisition unit 15 determines that the user is not a person, the user information acquisition unit 15 determines whether or not the user has an abnormality. The user information acquisition unit 15 determines that an abnormality has occurred in the user when the temperature of the user falls within the abnormal temperature range at a part or all of the time during the measurement time t. do.

In this example, the user information acquisition unit 15 determines that the user is not a person at the time when the temperature outside the human determination temperature range is acquired as the user's temperature. In addition, the user information acquisition unit 15 determines that an abnormality has occurred in the user at the time when the temperature within the abnormal temperature range is acquired as the temperature of the user. The user information acquisition unit 15 may perform both determination as to whether or not the user is a person and determination as to whether or not there is an abnormality in a user who is not a person at the time when the measurement ends.

When the user information acquisition unit 15 does not determine the abnormality of the user, the control panel 9 corresponding to the car 8 to which the user's call is assigned brings the car 8 on which the user has boarded to the destination floor. Run. On the other hand, when determining the abnormality of the user, the user information acquisition unit 15 issues a report of the abnormality to the monitoring device 3. At this time, the control panel 9 corresponding to the car 8 to which the user's call is assigned makes the car 8 stand by, for example, on the departure floor.

FIG. 5 shows an example of selecting the destination floor in the energy saving mode. In this example, the building has 20 floors from the 1st floor to the 20th floor. The free address area covers 19 floors from the 2nd floor to the 20th floor.

In FIG. 5, the amount of energy used on each floor is shown. In this example, the amount of energy used is represented in four stages of "large", "medium", "small", and "none" in descending order. In FIG. 5, the vacancy rate is shown as the vacancy status of each floor. The user moves from the platform 5 on the first floor, which is the departure floor, to the area of the free address.

The floor information acquisition unit 13 acquires the floor information of each floor from the monitoring device 3. Here, the floor information acquired by the floor information acquisition unit 13 in the energy saving mode includes at least information on the amount of energy used. In the example shown in FIG. 5, the floor information acquired by the floor information acquisition unit 13 includes energy usage information and vacancy rate information. The floor information acquisition unit 13 outputs the acquired floor information to the call processing unit 16.

The user registers a landing call to move to the free address area on the landing operation panel 6 on the first floor.

The call processing unit 16 extracts a floor having a "large" energy consumption as a candidate for a destination floor from a plurality of floors provided with a free address area. In this example, the floors with "large" energy consumption are the 2nd, 16th, and 17th floors. At this time, the call processing unit 16 extracts the second floor, the 16th floor, and the 17th floor as candidates for the destination floor. When there is no floor with "large" energy consumption, the call processing unit 16 uses a floor with "medium" energy consumption from a plurality of floors provided with a free address area as a destination floor. It may be extracted as a candidate. Further, when there is no floor with "large" and "medium" energy consumption, the call processing unit 16 selects a floor with "small" energy consumption from a plurality of floors provided with a free address area. It may be extracted as a candidate for the destination floor. Further, the call processing unit 16 sets all the floors provided with the free address area as candidates for the destination floor when there are no floors with "large", "medium", and "small" energy consumption. It may be extracted.

The call processing unit 16 selects a more vacant floor as a destination floor with higher priority based on the availability information from the floors extracted as candidates for the destination floor. In this example, the vacancy rate on the second floor is 0%. The vacancy rate on the 16th floor is 10%. The vacancy rate on the 17th floor is 20%. At this time, the call processing unit 16 selects the 17th floor as the destination floor of the user.

Alternatively, when the energy consumption is expressed numerically, the call processing unit 16 may select the floor with the larger energy consumption as the destination floor with higher priority. For example, the call processing unit 16 selects the floor that uses the largest amount of energy as the destination floor of the user.

Subsequently, an example of the operation of the elevator system 1 will be described with reference to FIGS. 6 and 7.
6 and 7 are flowcharts showing an example of the operation of the elevator system 1 according to the first embodiment.

FIG. 6 shows an example of the operation of the elevator system 1 related to the processing of the user's call.

In step S11, the user information acquisition unit 15 acquires the temperature information of the user at the landing 5 on the departure floor. After that, the operation of the elevator system 1 related to the call processing proceeds to step S12.

In step S12, the call information acquisition unit 14 determines whether the landing call to move to the free address area is registered on the landing operation panel 6. When the determination result is No, the operation of the elevator system 1 related to the call processing proceeds to step S11. When the determination result is Yes, the operation of the elevator system 1 related to the call processing proceeds to step S13.

In step S13, the call processing unit 16 determines whether the operation mode is the normal mode. When the determination result is Yes, the operation of the elevator system 1 related to the call processing proceeds to step S14. On the other hand, when the operation mode of the call processing unit 16 is the energy saving mode, the call processing unit 16 sets the determination result to No. At this time, the operation of the elevator system 1 related to the call processing proceeds to step S16.

In step S14, the floor information acquisition unit 13 acquires the floor information of each floor including at least the floor temperature information from the monitoring device 3. After that, the operation of the elevator system 1 related to the call processing proceeds to step S15.

In step S15, the call processing unit 16 corresponds to the procedure described with reference to, for example, FIG. 3 based on the temperature of the user who registered the landing call and the floor information including the floor temperature information. Select the destination floor of the user. The call processing unit 16 assigns the landing call for which the destination floor is selected to any of the cars 8. The landing call for which the destination floor is selected is registered in the assigned car 8. After that, the operation of the elevator system 1 related to the call processing ends.

In step S16, the floor information acquisition unit 13 acquires the floor information of each floor including at least the energy consumption information from the monitoring device 3. After that, the operation of the elevator system 1 related to the call processing proceeds to step S17.

In step S17, the call processing unit 16 selects the destination floor of the user based on the floor information including the energy consumption information, for example, by the procedure described with reference to FIG. The call processing unit 16 assigns the landing call for which the destination floor is selected to any of the cars 8. The landing call for which the destination floor is selected is registered in the assigned car 8. After that, the operation of the elevator system 1 related to the call processing ends.

FIG. 7 shows an example of the operation of the elevator system 1 related to the movement from the departure floor to the destination floor.

In step S21, the user information acquisition unit 15 acquires information on the temperature of the user who rides in the car 8 to which the landing call is assigned. After that, the operation of the elevator system 1 related to the movement from the departure floor to the destination floor proceeds to step S22.

In step S22, the user information acquisition unit 15 determines whether or not the user is a person based on the temperature of the user. When the determination result is Yes, the operation of the elevator system 1 related to the movement from the departure floor to the destination floor proceeds to step S23. When the determination result is No, the operation of the elevator system 1 related to the movement from the departure floor to the destination floor proceeds to step S24.

In step S23, the user information acquisition unit 15 outputs a determination result based on the user's temperature to the control panel 9 corresponding to the car 8 to which the landing call is assigned. The control panel 9 into which the determination result is input causes the corresponding car 8 to travel to the destination floor. After that, the operation of the elevator system 1 related to the movement from the departure floor to the destination floor ends.

In step S24, the user information acquisition unit 15 determines whether or not an abnormality has occurred in the user based on the temperature of the user. When the determination result is No, the operation of the elevator system 1 related to the movement from the departure floor to the destination floor proceeds to step S23. When the determination result is Yes, the operation of the elevator system 1 related to the movement from the departure floor to the destination floor proceeds to step S25.

In step S25, the user information acquisition unit 15 reports an abnormality to the monitoring device 3. The user information acquisition unit 15 outputs a determination result based on the temperature of the user to the control panel 9 corresponding to the car 8 to which the landing call is assigned. The control panel 9 into which the determination result is input causes the corresponding car 8 to stand by on the departure floor. After that, the operation of the elevator system 1 related to the movement from the departure floor to the destination floor ends.

As described above, the elevator system 1 according to the first embodiment includes a user information acquisition unit 15, a floor information acquisition unit 13, and a call processing unit 16. The user information acquisition unit 15 acquires information on the temperature of the user at the landing 5. The temperature of the user at the landing 5 is measured by, for example, a first infrared sensor 7 provided at the landing 5. The floor information acquisition unit 13 acquires floor information. The floor information includes information on the floor temperature of each of a plurality of floors provided with a free address area. When the call of the user who moves to the area of the free address is received, the call processing unit 16 selects the destination floor of the user from the plurality of floors. The destination floor is selected based on the information on the temperature of the user acquired by the user information acquisition unit 15 and the information on the floor temperature of each floor acquired by the floor information acquisition unit 13.

Since the user can use any floor in the free address area in the same way, there is room for the user's destination floor to be selected by the elevator system 1. The destination floor is selected based on the temperature of the user and the floor temperature of the floor that the user can spend after getting off the car 8. Therefore, the elevator system 1 can increase the possibility that the user feels comfortable after getting off the car 8. Further, the elevator system 1 can select a floor in an environment in which the moving body can operate satisfactorily as a destination floor even for a user such as a moving body who is not a person.

Further, the call processing unit 16 selects the destination floor of the user who received the call to move to the free address area based on the lower limit comfortable temperature and the upper limit comfortable temperature. The call processing unit 16 selects a floor whose floor temperature is included in the temperature range between the lower limit comfortable temperature and the upper limit comfortable temperature calculated from the temperature of the user as the destination floor. When there is no floor whose floor temperature is included in the temperature range between the lower limit comfortable temperature and the upper limit comfortable temperature, the call processing unit 16 performs the destination floor from all of the plurality of floors provided with the free address area. Select a floor. Here, each of the lower limit comfortable temperature and the upper limit comfortable temperature is calculated by a monotonous non-increasing relationship with respect to the user's temperature.
Further, the call processing unit 16 may select the destination floor of the user who has received the call to move to the free address area based on the central comfortable temperature. The call processing unit 16 selects the destination floor by giving priority to the floor whose floor temperature is closer to the central comfortable temperature calculated from the temperature of the user. Here, the central comfortable temperature is calculated by a monotonous non-increasing relationship with respect to the user's temperature.
The monotonically non-increasing relationship may be, for example, a relationship by a step function including one or more discontinuities, a relationship by a monotonically decreasing function, or a relationship by a function combining these. A monotonically decreasing function is, for example, a linear function with respect to the user's temperature, a piecewise polynomial or rational function with respect to the user's temperature, a logarithmic function with a monotonically decreasing gradient with respect to the user's temperature, or a gradient with respect to the user's temperature. It may be an exponential function that increases monotonically.

As a result, for example, a user with a large amount of activity and a high body temperature can spend comfortably on a cool floor with a low floor temperature. In addition, a user having a high body temperature due to moving outdoors, for example, can spend comfortably on a cool floor with a low floor temperature. In addition, a user having a low body temperature due to moving outdoors, for example, can spend comfortably on a warm floor with a high floor temperature. Further, for example, a user with a small amount of activity and a low body temperature can spend comfortably on a warm floor with a high floor temperature. Therefore, the elevator system 1 can further increase the possibility that the user feels comfortable after getting off the car 8.

Further, the call processing unit 16 determines whether the temperature of the user who received the call to move to the free address area is higher than the preset threshold value. When it is determined that the value is higher than the threshold value, the call processing unit 16 preferentially assigns the call of the user to the car 8 in which the number of passengers is less than the plurality of cars 8.

The room temperature of the vacant car 8 is often lower than the room temperature of the crowded car 8 because there are few passengers on board. As a result, for example, a user with a large amount of activity and a high body temperature can spend comfortably in the vacant car 8. In addition, a user having a high body temperature due to moving outdoors, for example, can spend comfortably in an empty car 8. The elevator system 1 can increase the possibility that the user feels comfortable even in the car 8.

Further, the floor information acquisition unit 13 acquires information on the availability of each of the plurality of floors as floor information. When the call of the user who moves to the area of the free address is received, the call processing unit 16 selects the destination floor of the user from the plurality of floors. The destination floor is based on the information on the temperature of the user acquired by the user information acquisition unit 15, the information on the floor temperature of each floor acquired by the floor information acquisition unit 13, and the information on the availability. Be selected.

Since availability information is used to select the destination floor, problems such as no available seats on the selected destination floor are unlikely to occur. In addition, since the availability information is used to select the destination floor, the options such as the seats used by the user on the selected destination floor are widened. Therefore, the elevator system 1 can further increase the possibility that the user feels comfortable after getting off the car 8.

In addition, the user information acquisition unit 15 acquires information on the temperature of the user who rides in the car 8. The temperature of the user riding in the car 8 is measured by, for example, a second infrared sensor 12 provided in the car 8. Based on the change in the temperature of the user over time, the user information acquisition unit 15 determines whether or not the user is a person, and the temperature of the user falls within a preset abnormal temperature range. Determine if it is included. When the user information acquisition unit 15 determines that the user is not a person and the temperature of the user is included in the abnormal temperature range, the user information acquisition unit 15 issues a report to the monitoring device 3. The monitoring device 3 is a device that monitors the state of the building to which the elevator system 1 is applied.

When an abnormality occurs in the moving body in the car 8, the monitoring device 3 can grasp the occurrence of the abnormality. This makes it possible to promptly deal with the abnormality, including discontinuing the use of the moving body or performing maintenance such as repair.

Further, the call processing unit 16 outputs the selected destination floor information and the user temperature information acquired by the user information acquisition unit 15 to the management device 4. The management device 4 is a device that manages the air conditioning of the building to which the elevator system 1 is applied.

As a result, the management device 4 can manage the air conditioning according to the user spending on each floor. The management device 4 can lower the floor temperature on the floor where many users with high body temperature spend, for example, due to a large amount of activity. The management device 4 can raise the floor temperature on the floor where many users with low body temperature spend, for example, due to a small amount of activity. Therefore, the elevator system 1 can further increase the possibility that the user feels comfortable after getting off the car 8.

Further, the call processing unit 16 operates based on an operation mode in which the normal mode and the energy saving mode can be switched. The floor information acquisition unit 13 acquires information on the energy consumption of each floor as floor information when the operation mode of the call processing unit 16 is the energy saving mode. When the call of the user who moves to the area of the free address is received, the call processing unit 16 selects the destination floor of the user from the plurality of floors. When the operation mode of the call processing unit 16 is the energy saving mode, the destination floor is selected based on the energy consumption information of each floor acquired by the floor information acquisition unit 13.

The call processing unit 16 can allocate the floors spent by the user to each floor according to the amount of energy used by selecting the destination floor. For example, the call processing unit 16 can suppress the amount of energy used by air conditioning in the entire building by concentrating the floors spent by the users.

Further, the operation mode of the call processing unit 16 is switched based on the information of the electric power demand of the building to which the elevator system 1 is applied.

As a result, the amount of energy used in the entire building is suppressed according to the amount of electricity demand. For example, when a high power demand is expected, the elevator system 1 can operate to reduce the energy consumption. The operation of reducing the energy consumption includes, for example, suspending the car 8 to limit the number of cars 8 responding to the landing call, or assigning the call so as to minimize the mileage of the car 8.

The operation mode of the call processing unit 16 may be switched based on a preset schedule. For example, the operation mode may be switched to the energy saving mode during the daytime of the day. Alternatively, the operation mode may be switched to the energy saving mode at night time of the day. Alternatively, the operating mode may be switched to the energy saving mode on business days of the week. Alternatively, the operation mode may be switched to the energy saving mode on a holiday during the week. Alternatively, the operating mode may be switched to the energy saving mode in the summer or winter of the year. Alternatively, the operating mode may be switched to the energy saving mode during the off-season of the year in the building. Further, the operation mode of the call processing unit 16 may be switched by a manual operation such as a building manager.

Also, there may be multiple free address areas in one building. When there is a call from a user who moves to any of the free address areas, the call processing unit 16 selects the destination floor from the floors provided with the free address area. For example, when the free address area is provided on a part of one of the floors, the plurality of free address areas may be provided over the range of the floors overlapping each other.

Further, the landing operation panel 6 may accept an operation of selecting a candidate for the destination floor by the user. For example, when the free address area covers 9 floors from the 2nd floor to the 10th floor, the user selects a range such as the 4th floor from the 3rd floor to the 6th floor as a candidate for the destination floor. You may. At this time, the call processing unit 16 selects the destination floor from the floors selected by the user as candidates, based on the user's temperature, the floor temperature, and the like.

Further, the call information acquisition unit 14 may acquire call information from a mobile terminal possessed by a user in the free address area. The mobile terminal is a portable information terminal such as a smartphone. The call from the mobile terminal includes, for example, information on the departure floor and information for identifying a free address used by the user.

Further, the user information acquisition unit 15 may acquire user information from other devices or devices of the first infrared sensor 7 and the second infrared sensor 12. The user information acquisition unit 15 may acquire information such as a measured value of the temperature of the user measured by the wearable device worn by the user, for example.

Further, the elevator system 1 may include one car 8 and one control panel 9. At this time, the elevator system 1 does not have to be provided with the group management device. A part or all of the floor information acquisition unit 13, the call information acquisition unit 14, the user information acquisition unit 15, and the call processing unit 16 may be provided on the control panel 9.
