Detailed Description

A mode for carrying out the present invention will be described with reference to the accompanying drawings. In the drawings, the same or corresponding portions are denoted by the same reference numerals, and overlapping description is simplified or omitted as appropriate.

Embodiment mode 1

Fig. 1 is a configuration diagram of an elevator system 1 according to embodiment 1.

In fig. 1, an example of the structure of a building system 2 comprising an elevator system 1 is shown. 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 (also called hot-clearing) area. A 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 does not have a specific fixed seat but uses an empty seat. The free address area is, for example, an office area where a user works. Alternatively, the free address area may be an area such as a library or a library in which the user views the material. In this example, any of a plurality of floors provided with a free address area can be used by a user of 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 a building. The state of the building includes, for example, floor information of each floor and a power demand of the building. The floor information includes, for example, floor temperature information, free condition information, energy usage information, and the like. The floor temperature of a floor is, for example, the air temperature at 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. The free state of the floor is monitored for the floor where the free address area is provided. The vacant status of a floor is, for example, the number of vacant seats or the vacant seat rate in the floor. The energy usage of a floor is the amount of energy used in connection with that floor. The energy usage amount of a floor is, for example, the amount of energy used for air conditioning of the floor. The management apparatus 4 is an apparatus that manages the environment of the building. The management device 4 manages the operation of an air conditioner, not shown, installed in a building, for example.

A building is provided with a hoistway not shown. The hoistway is a vertically long space that spans a plurality of floors. Each floor is provided with a landing 5. A landing 5 on each floor is provided with a landing operating panel 6 and a first infrared sensor 7.

The landing operating panel 6 is a device that receives an operation by a user of the elevator system 1. The landing operation panel 6 receives an operation of a user, for example, through a touch panel or the like. The operation received by the landing operation panel 6 is, for example, a landing call operation. The hall call operation is an operation in which a user calls the car 8 from the hall 5. The hall operation panel 6 receives a hall call operation by a user who wants to move to a free address area.

The first infrared sensor 7 is a device for measuring the temperature of a user of the elevator system 1 located in the landing 5 by using infrared rays. The user of the elevator system 1 is e.g. a person. The first infrared sensor 7 measures the body temperature of a person present at the landing 5 as the temperature of the user of the person. The body temperature measured here is the body surface temperature. 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 located at the landing 5 as the temperature of the user.

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

Each car 8 is installed in a hoistway. Each car 8 is a device that transports users and the like between a plurality of floors by traveling in a vertical direction in a hoistway. Each car 8 is provided with a car operating panel 11 and a second infrared sensor 12. The car operating panel 11 is a device that receives an operation by a user of the elevator system 1. The car operation panel 11 receives user operations through a plurality of buttons and the like, for example. The operation received by the car operation panel 11 is, for example, a car call operation. The car call operation is an operation in which a user designates a destination floor from the car 8. The second infrared sensor 12 is a device for measuring the temperature of a user of the elevator system 1 riding on the car 8 by using infrared rays.

Each control panel 9 corresponds to an arbitrary car 8. Each control panel 9 controls the operation of the corresponding car 8. The operation of the car 8 includes, for example, traveling of the car 8.

The group control 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 acquiring unit 13 is a part that acquires floor information of each floor. The floor information acquiring unit 13 is connected to the monitoring device 3 so as to acquire floor information, for example.

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

The user information acquiring unit 15 is a part that acquires information of a user of the elevator system 1. The user information acquiring unit 15 acquires information such as a measured value of the user temperature measured by the first infrared sensor 7. The user information acquiring unit 15 acquires information such as a measured value of the user temperature measured by the second infrared sensor 12. The user information acquiring unit 15 is provided with a function of determining whether or not there is an abnormality based on the acquired information. When determining that there is an abnormality, the user information acquiring unit 15 reports the abnormality to the monitoring device 3. The report to the monitoring device 3 may be made by the floor information acquisition unit 13.

The call processing section 16 is a section that processes calls of users. The call processing in the call processing section 16 includes, for example, selection of a destination floor of a call and assignment of a call to any car 8 of the plurality of cars 8.

The destination floor in the call processing section 16 is selected based on the floor information of each floor acquired by the floor information acquisition section 13, the call information acquired by the call information acquisition section 14, and the user information acquired by the user information acquisition section 15. The destination floor is selected, for example, according to the comfort temperature of the user. Here, the comfortable temperature of the user is calculated in the call processing section 16 based on the temperature of the user acquired by the user information acquiring section 15, for example.

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

The call processing unit 16 operates based on the 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 normal operation of the elevator system 1, the operation mode of the call processing section 16 is set to the normal mode. The operation mode of the call processing unit 16 is switched, for example, in response to a mode switching signal input from the monitoring device 3. The mode switching signal may be input by the floor information acquisition unit 13.

In this example, the monitoring device 3 outputs a mode switching signal in accordance with the power demand of the building, for example, as follows. The monitoring device 3 estimates the future power demand from the power demand of the building up to the present time. 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.

Next, the comfort temperature used for selecting the destination floor will be described with reference to fig. 2.

Fig. 2 is a diagram showing an example of comfort temperature in the elevator system 1 according to embodiment 1.

The horizontal axis of fig. 2 represents the temperature of the user. The vertical axis of fig. 2 represents comfort temperature.

The comfort temperature is a temperature contained within a comfort temperature range. The comfort temperature range is a temperature range between a lower comfort temperature and an upper comfort temperature. The comfort temperature range includes the central comfort temperature. The center comfort temperature is a temperature intermediate the lower comfort temperature and the upper comfort temperature. The center comfort temperature is an example of a comfort temperature.

The lower comfort temperature is calculated by a monotonically non-increasing relationship with respect to the temperature of the user. Here, the relationship of the monotone non-increase may be, for example, a relationship based on a step function including one or more discontinuous points, a relationship based on a function of the monotone decrease, a relationship based on a function in which these are combined, or the like. The monotonically decreasing function includes, for example, a linear function with respect to the temperature of the user, a piecewise polynomial function or rational function with respect to the temperature of the user, a logarithmic function in which the gradient monotonically decreases with respect to the temperature of the user, or an exponential function in which the gradient monotonically increases with respect to the temperature of the user. The lower comfort temperature is calculated, for example, by a monotonically decreasing function with respect to the temperature of the user. In this example, the lower comfort temperature is calculated as a linear function with respect to the temperature of the user.

The upper limit comfort temperature is calculated by a monotonically non-increasing relationship with respect to the temperature of the user. Here, the relationship of monotonic non-increase may be a relationship based on a step function including one or more discontinuous points, a relationship based on a function of monotonic decrease, a relationship based on a function combining these, or the like. The monotonically decreasing function includes, for example, a linear function with respect to the temperature of the user, a piecewise polynomial function or rational function with respect to the temperature of the user, a logarithmic function in which the gradient monotonically decreases with respect to the temperature of the user, or an exponential function in which the gradient monotonically increases with respect to the temperature of the user. The upper limit comfort temperature is calculated, for example, by a monotonically decreasing function with respect to the temperature of the user. In this example, the upper limit temperature is calculated as a linear function with respect to the temperature of the user.

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

The center comfort temperature is calculated by a monotonically non-increasing relationship with respect to the temperature of the user. Here, the relationship of monotonic non-increase may be a relationship based on a step function including one or more discontinuous points, a relationship based on a function of monotonic decrease, a relationship based on a function combining these, or the like. The monotonically decreasing function includes, for example, a linear function with respect to the temperature of the user, a piecewise polynomial function or rational function with respect to the temperature of the user, a logarithmic function in which the gradient monotonically decreases with respect to the temperature of the user, or an exponential function in which the gradient monotonically increases with respect to the temperature of the user. The central comfort temperature is calculated, for example, by a monotonically decreasing function with respect to the temperature of the user. In this example, the center comfort temperature is calculated as a linear function with respect to the temperature of the user. The central comfort temperature is for example the arithmetic mean temperature of the lower comfort temperature and the upper comfort temperature. In this example, the rate of change of the center comfort temperature with respect to the temperature of the user is equal to the rate of change of the lower limit comfort temperature with respect to the temperature of the user and the rate of change of the upper limit comfort temperature with respect to the temperature of the user.

For example, when the body temperature of the human user is 36.0 ℃, the lower limit comfortable temperature is set to 23.0 ℃. In addition, the upper comfort temperature is set to 25.0 ℃. The central comfort temperature was set to 24.0 ℃.

Next, the functions of the elevator system 1 will be described with reference to fig. 3 to 5.

Fig. 3 and 5 are diagrams showing examples of the selection of a destination floor by the call processing part 16 in embodiment 1.

Fig. 4 is a diagram showing an example of the determination performed by the user information acquisition unit 15 according to embodiment 1.

In fig. 3, an example of the selection of a destination floor in normal mode is shown. In this example, the building has 20 floors from 1 floor to 20 floors. The free address area is 19 floors from 2 floors to 20 floors.

In fig. 3, the floor temperatures of the respective floors are shown. In fig. 3, the unoccupied seat rate is shown as the vacant state of each floor. In this example, the user is a human. The body temperature of the user was 36.0 ℃. The user moves from the landing 5 on floor 1 as the starting floor to the free address area.

The first infrared sensor 7 measures the temperature of a user at the landing 5 on floor 1 as the starting floor. The user information acquiring unit 15 acquires the measured value of the temperature of the user from the first infrared sensor 7. The user information acquiring unit 15 outputs the acquired information to the call processing unit 16.

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

The user performs a hall call operation on the hall operation panel 6 on floor 1 as follows, for example.

The landing operating panel 6 displays, for example, one button corresponding to the entire free address area on the touch panel. In this example, the landing operating panel 6 displays one button corresponding to a range from 2 floors to 20 floors. The user registers a hall call for a floor in a range in which a free address area is provided by operating the button.

Alternatively, the landing operating panel 6 may display, on the touch panel, a plurality of buttons corresponding to a plurality of floors provided with free address areas, for example. In this example, the landing operating panel 6 displays 19 buttons corresponding to floors from 2 floors to 20 floors. The user registers a hall call for a range of floors in which a free address area is provided by operating any of the 19 buttons. In this example, even if the user operates any of the 19 buttons, a hall call for the same range is registered.

The call information acquisition unit 14 acquires hall call information of a user from the hall 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 of a hall call moving to a free address area from the hall operating 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 a lower limit comfort temperature and an upper limit comfort temperature from the temperature of the user. In this example, the call processing part 16 calculates the lower limit comfortable temperature to be 23.0 ℃ from the body temperature of the user of 36.0 ℃. The call processing unit 16 calculates the upper comfortable temperature to be 25.0 ℃ from the body temperature of the user of 36.0 ℃. The call processing section 16 extracts, as a candidate of a destination floor, a floor whose floor temperature is included in the comfort temperature range from among a plurality of floors provided with free address areas. In this example, the floor temperature of 2 floors is 23.1 degrees. The floor temperature of the 17 th floor was 24.2 ℃. At this time, the call processing section 16 extracts the 2 nd floor and the 17 th floor as candidates of the destination floor.

The call processing unit 16 selects, as the destination floor, a floor that is more vacant, from among floors extracted as candidates for the destination floor, based on the vacant situation information, with higher priority. In this example, the vacancy rate of 2 layers is 0%. The vacancy rate of 17 layers was 20%. At this time, the call processing section 16 selects the 17 th floor as the destination floor of the user.

Alternatively, the call processing unit 16 may preferentially select a floor whose floor temperature is closer to the center comfort temperature as the destination floor. The call processing section 16 calculates a center comfort temperature from the temperature of the user. In this example, the call processing part 16 calculates the lower limit comfortable temperature to be 24.0 ℃ from the body temperature of the user of 36.0 ℃. The call processing unit 16 searches for a floor whose floor temperature is close to the center comfort temperature from among a plurality of floors provided with free address areas. In this example, the floor temperature of floor 17.2 ℃ is closest to the central comfort temperature. At this time, the call processing section 16 selects the 17 th floor as the destination floor of the user.

The call processing unit 16 assigns a call for which a destination floor is selected to any of the plurality of cars 8. The call processing unit 16 determines whether or not the temperature of the user measured at the hall 5 is higher than a preset threshold value. The threshold is set to a value equal to or higher than the average body temperature of the user who is a human being, for example. 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 assigned car 8, for example, in accordance with 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 portion 16 preferentially assigns the car 8 with a smaller number of users. Here, the number of users boarding each car 8 is calculated from the hall call information and the car call information acquired by the call information acquisition unit 14.

The call processing unit 16 outputs information of the selected destination floor and temperature information of the user 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 comfort temperature of the user who moves 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 section 16 outputs information of the call including 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 to which the call information is input causes the corresponding car 8 to travel to the departure floor of the user in accordance with the call.

The call processing unit 16 outputs information of the call, including information of the car 8 to which the call is assigned and the selected destination floor, to the hall operating panel 6 provided at the user's departure floor. The landing operating panel 6 provided at the user's departure floor notifies the selected destination floor and the assigned car 8. The hall operation panel 6 notifies the user of a display on a touch panel, a voice broadcast through a speaker, or the like.

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

After that, the car 8 to which the call is assigned stops at the departure floor. The second infrared sensor 12 measures the temperature of a user riding on the car 8 stopped at the departure floor. The user information acquiring unit 15 acquires the measured value of the temperature of the user from the second infrared sensor 12. The user information acquiring unit 15 determines whether there is an abnormality based on the acquired temperature information of the user.

Fig. 4 shows an example of the determination performed by the user information acquisition unit 15.

The horizontal axis of fig. 4 represents time. The vertical axis of fig. 4 represents the measured value of the measured temperature of the user.

The user information acquiring unit 15 sets a person determination temperature range and an abnormal temperature range in advance. The person determination temperature range is a temperature range for determining whether or not the user is a person. The abnormal temperature range is a temperature range for determining whether or not there is an abnormality in the user. The human determination temperature range is set to a temperature range of, for example, 34.0 ℃ to 40.0 ℃. The lower limit temperature of the abnormal temperature range is set to a temperature higher than the upper limit temperature of the human determination temperature range, for example.

The user information acquiring unit 15 determines the temperature of the user based on the change of the measured value with the passage of time. The change in temperature with the passage of time is measured for a preset measurement time t from the start of measurement to the end of measurement. The measurement time t is set to several seconds, for example.

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

In this example, the user information acquiring unit 15 determines that the user is not a person when a temperature outside the person determination temperature range is acquired as the temperature of the user. The user information acquiring unit 15 determines that an abnormality has occurred in the user when the temperature within the abnormal temperature range is acquired as the temperature of the user. The user information acquiring unit 15 may determine whether or not the user is a human at the time of completion of the measurement, and may determine whether or not the user is not a human.

When the user information acquiring portion 15 does not determine that the user is abnormal, the control panel 9 corresponding to the car 8 to which the call of the user is assigned causes the car 8 on which the user boards to travel to the destination floor. On the other hand, when the abnormality of the user is determined, the user information acquiring unit 15 reports the abnormality to the monitoring device 3. At this time, the control panel 9 corresponding to the car 8 to which the call of the user is assigned, for example, causes the car 8 to wait at the departure floor.

In fig. 5, an example of the selection of a destination floor in energy saving mode is shown. In this example, the building has 20 floors from 1 floor to 20 floors. The free address area spans 19 floors from floor 2 to floor 20.

In fig. 5, energy usage amounts of respective floors are shown. In this example, the energy usage is represented by 4 levels of "large", "medium", "small", and "none" in order from large to small. Fig. 5 shows the vacant seat ratios as vacant statuses of the respective floors. The user moves from the landing 5 on floor 1 as the starting floor to the free address area.

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

The user registers a hall call moving to a free address area in the hall operation panel 6 of level 1.

The call processing unit 16 receives hall call information moving to a free address area from the hall operating panel 6. At this time, the call processing unit 16 selects the destination floor of the accepted call as follows, for example.

The call processing unit 16 extracts a floor whose energy usage is "large" as a candidate for a destination floor from a plurality of floors provided with a free address area. In this example, the floors whose energy usage amount is "large" are

floors

2, 16, and 17. At this time, the call processing section 16 extracts the 2-, 16-and 17-floors as candidates of the destination floor. In addition, when there is no floor whose energy usage is "large", the call processing unit 16 may extract a floor whose energy usage is "medium" from a plurality of floors provided with a free address area as a candidate for a destination floor. In addition, when there are no floors whose energy usage amounts are "large" and "medium", the call processing unit 16 may extract a floor whose energy usage amount is "small" as a candidate for a destination floor from a plurality of floors provided with a free address area. In addition, the call processing unit 16 may extract all floors provided with a free address area as candidates of destination floors when there are no floors whose energy usage amounts are "large", "medium", and "small".

The call processing unit 16 selects, as the destination floor, a floor that is more vacant, from among floors extracted as candidates for the destination floor, based on the vacant situation information, with higher priority. In this example, the vacancy rate of 2 layers is 0%. The vacancy rate of 16 layers was 10%. The vacancy rate of 17 layers was 20%. At this time, the call processing section 16 selects the 17 th floor as the destination floor of the user.

Alternatively, when the energy usage is represented by a numerical value, the call processing unit 16 may select a floor having a larger energy usage as the destination floor with higher priority. For example, the call processing unit 16 selects the floor with the largest energy usage amount as the destination floor of the user.

Next, an operation example of the elevator system 1 will be described with reference to fig. 6 and 7.

Fig. 6 and 7 are flowcharts showing an operation example of the elevator system 1 according to embodiment 1.

Fig. 6 shows an example of the operation of the elevator system 1 related to call handling by a user.

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

In step S12, the call information acquisition section 14 determines whether or not a hall call to be moved to a free address area is registered in the hall operation panel 6. If the determination result is "no", the operation of the elevator system 1 relating to the call handling proceeds to step S11. If the determination result is yes, the operation of the elevator system 1 relating to the call handling proceeds to step S13.

In step S13, the call processing unit 16 determines whether or not the operation mode is the normal mode. If the determination result is yes, the operation of the elevator system 1 relating to the call handling 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 acquiring unit 13 acquires 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 section 16 selects a destination floor of a user who has performed hall call registration, for example, in accordance with the procedure described with reference to fig. 3, based on the temperature of the user and floor information including floor temperature information. The call processing unit 16 assigns a landing call of the selected destination floor to an arbitrary car 8. A landing call for which a destination floor is selected is registered to the assigned car 8. After that, the operation of the elevator system 1 related to the call processing is ended.

In step S16, the floor information acquisition unit 13 acquires floor information of each floor including at least energy usage 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 section 16 selects the destination floor of the user, for example, according to the procedure described with reference to fig. 5, based on the floor information including the energy usage information. The call processing unit 16 assigns a landing call of the selected destination floor to an arbitrary car 8. A landing call for which a destination floor is selected is registered to the assigned car 8. After that, the operation of the elevator system 1 related to the call processing is ended.

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

In step S21, the user information obtaining portion 15 obtains temperature information of a user riding on the car 8 to which a hall call is assigned. Thereafter, the operation of the elevator system 1 relating to the movement from the departure floor to the destination floor proceeds to step S22.

In step S22, the user information acquiring unit 15 determines whether or not the user is a human based on the temperature of the user. If the determination result is yes, the operation of the elevator system 1 relating to the movement from the departure floor to the destination floor proceeds to step S23. If the determination result is "no," the operation of the elevator system 1 relating 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 the determination result based on the temperature of the user to the control panel 9 corresponding to the car 8 to which the hall call is assigned. The control panel 9 to 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 relating to the movement from the departure floor to the destination floor is ended.

In step S24, the user information acquiring unit 15 determines whether or not an abnormality has occurred in the user based on the temperature of the user. If the determination result is "no," the operation of the elevator system 1 relating to the movement from the departure floor to the destination floor proceeds to step S23. If the determination result is yes, the operation of the elevator system 1 relating to the movement from the departure floor to the destination floor proceeds to step S25.

In step S25, the user information acquiring unit 15 reports an abnormality to the monitoring device 3. The user information acquiring unit 15 outputs the result of determination based on the temperature of the user to the control panel 9 corresponding to the car 8 to which the hall call is assigned. The control panel 9 to which the determination result is input causes the corresponding car 8 to wait at the departure floor. After that, the operation of the elevator system 1 relating to the movement from the departure floor to the destination floor is completed.

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

In the free address area, the user can similarly use an arbitrary floor, and therefore the destination floor of the user has room 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 may spend after getting off the car 8. Therefore, the elevator system 1 can improve the possibility that the user feels comfortable after getting off the elevator car 8. In addition, the elevator system 1 can select, as a destination floor, a floor having an environment in which a user such as an unmanned moving body can run well, for the user.

The call processing unit 16 selects a destination floor of a user who has received a call to move to a 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 a temperature range between a lower limit comfort temperature and an upper limit comfort temperature calculated from the temperature of the user as a 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 part 16 selects a destination floor from all of the floors in which the free address area is provided. Here, the lower limit comfort temperature and the upper limit comfort temperature are each calculated by a relationship in which the temperature of the user monotonously increases.

The call processing unit 16 may select a destination floor of a user whose call to be moved to the free address area has been accepted, based on the center comfort temperature. The call processing unit 16 selects, as the destination floor, a floor whose floor temperature is closer to the center comfort temperature calculated from the temperature of the user with higher priority. Here, the center comfort temperature is calculated by a monotone non-increasing relationship with respect to the temperature of the user.

The relationship of the monotone non-increase may be, for example, a relationship based on a step function including one or more discontinuous points, a relationship based on a function of the monotone decrease, or a relationship based on a function obtained by combining these. The monotonously decreasing function may be, for example, a linear function with respect to the temperature of the user, a piecewise polynomial function or rational function with respect to the temperature of the user, a logarithmic function in which the gradient monotonously decreases with respect to the temperature of the user, or an exponential function in which the gradient monotonously increases with respect to the temperature of the user.

This enables a user with a large amount of activity and a high body temperature to comfortably pass through a cool floor with a low floor temperature. In addition, a user with a high body temperature, for example, who moves from a hot outdoor location, can comfortably pass through a cool floor with a low floor temperature. In addition, a user with a low body temperature, for example, who moves from a cold outdoor location, can comfortably pass through a warm floor with a high floor temperature. In addition, for example, a user with a small amount of activity and a low body temperature can comfortably pass through a warm floor with a high floor temperature. Therefore, the elevator system 1 further improves the possibility that the user feels comfortable after getting off the car 8.

The call processing section 16 also determines whether or not the temperature of the user who has received a call to move to a free address area is higher than a preset threshold value. When it is determined that the number of the users is higher than the threshold value, the call processing unit 16 assigns the call priority of the user to the car 8 having fewer users among the plurality of cars 8.

The temperature of the empty car 8 with fewer passengers is often lower than the temperature of the crowded car 8. This allows a user with a large amount of physical activity and a high body temperature to comfortably pass through the empty car 8. In addition, a user with a high body temperature, for example, who moves from a hot outdoor location, can comfortably pass through the empty car 8. The elevator system 1 can also improve the possibility that the user feels comfortable in the car 8.

The floor information acquiring unit 13 acquires the free state information of each of the plurality of floors as floor information. When receiving a call for a user who moves to a free address area, the call processing unit 16 selects a destination floor of the user from a plurality of floors. The destination floor is selected based on the temperature information of the user acquired by the user information acquiring unit 15, and the floor temperature information and the free state information of each floor acquired by the floor information acquiring unit 13.

Since the vacant status information is used for selecting the destination floor, there is less possibility of a problem that there is no available vacant seat in the selected destination floor. In addition, since the vacant state information is used for selecting the destination floor, options such as a seat used by a user are increased in the selected destination floor. Therefore, the elevator system 1 further improves the possibility that the user feels comfortable after getting off the elevator car 8.

The user information acquiring unit 15 acquires temperature information of a user riding on the car 8. The temperature of the user riding on the car 8 is measured by, for example, a second infrared sensor 12 or the like provided in the car 8. The user information acquiring unit 15 determines whether or not the user is a person and whether or not the temperature of the user is included in a preset abnormal temperature range, based on the temperature change of the user with the elapse of time. The user information acquiring unit 15 reports to the monitoring device 3 when it is determined that the user is not a person and the temperature of the user is included in the abnormal temperature range. The monitoring device 3 is a device for monitoring the state of a building to which the elevator system 1 is applied.

When an abnormality occurs in a moving body riding on the car 8, the monitoring device 3 can grasp the occurrence of the abnormality. This makes it possible to quickly cope with the abnormality, including suspension of use of the mobile body or maintenance such as repair.

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

Thus, the management device 4 can perform air conditioning management according to the users who have spent on the respective floors. The management device 4 can lower the floor temperature in a floor where there are many users whose body temperature is high due to, for example, a large amount of activity. The management device 4 can increase the floor temperature in a floor where there are many users who have low body temperatures due to, for example, a small amount of activity. Therefore, the elevator system 1 further improves the possibility that the user feels comfortable after getting off the elevator car 8.

The call processing unit 16 operates based on an operation mode that can switch between the normal mode and the energy saving mode. When the operation mode of the call processing unit 16 is the energy saving mode, the floor information acquisition unit 13 acquires energy usage information of each floor as floor information. When receiving a call for a user who moves to a free address area, the call processing unit 16 selects a destination floor of the user from a plurality of floors. When the operation mode of the call processing section 16 is the energy saving mode, the destination floor is selected based on the energy usage information of each floor acquired by the floor information acquisition section 13.

The call processing section 16 can assign a floor to be used by a user by selecting a destination floor, according to the amount of energy used. For example, the call processing unit 16 can suppress the amount of energy used by the air conditioner in the entire building by concentrating the floors that users spend on them.

The operation mode of the call processing unit 16 is switched according to the power demand information of the building to which the elevator system 1 is applied.

This suppresses the amount of energy used in the entire building in accordance with the amount of power demand. For example, when a high power demand is estimated, the elevator system 1 can perform an operation in which the amount of energy used is suppressed. The operation for suppressing the amount of energy usage includes, for example, stopping the operation of the car 8 to limit the number of cars 8 responding to a hall call, or assigning a call so that the travel distance of the car 8 becomes minimum.

The operation mode of the call processing unit 16 may be switched based on a schedule set in advance. 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 during the night of the day. Alternatively, the operation 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 during the weekend of the week. Alternatively, the operation mode may be switched to the energy saving mode in summer or winter of the year. Alternatively, the operation mode may be switched to the energy saving mode in an idle period of one year in the building. The operation mode of the call processing unit 16 may be switched by manual operation by a building manager or the like.

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

The landing operating panel 6 may receive an operation of selecting a candidate of a destination floor by a user. For example, in the case where the free address area spans nine floors from 2 th floor to 10 th floor, etc., the user may select a range of four floors from 3 th floor to 6 th floor, etc., as candidates for the destination floor. At this time, the call processing unit 16 selects a destination floor from floors selected as candidates by the user, based on the temperature of the user, the floor temperature, and the like.

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

The user information acquiring unit 15 may acquire user information from other devices or apparatuses than the first infrared sensor 7 and the second infrared sensor 12. The user information acquiring unit 15 may acquire information such as a measured value of the temperature of the user measured by a wearable device worn by the user.

The elevator system 1 may include 1 car 8 and 1 control panel 9. In this case, the elevator system 1 may not include the group control device. Some or all of the floor information acquisition part 13, the call information acquisition part 14, the user information acquisition part 15, and the call processing part 16 may be provided in the control panel 9. Some or all of the floor information acquiring part 13, the call information acquiring part 14, the user information acquiring part 15, and the call processing part 16 may be provided in other hardware such as the control panel 9 or the group control device of the elevator system 1. The hardware is, for example, a server computer or the like installed in a building.

Next, an example of the hardware configuration of the elevator system 1 will be described with reference to fig. 8.

Fig. 8 is a hardware configuration diagram of a main part of the elevator system 1 according to embodiment 1.

The functions of the elevator system 1 can be implemented by means of a processing circuit. The processing circuit is provided with at least one processor 100a and at least one memory 100b. The processing circuit may include at least one dedicated hardware 200 together with the processor 100a and the memory 100b, or may include at least one dedicated hardware 200 instead of the processor 100a and the memory 100b.

In the case of a processing circuit provided with a processor 100a and a memory 100b, the functions of the elevator system 1 are implemented by software, firmware or a combination of software and firmware. At least one of the software and the firmware is described as a program. The program is stored in the memory 100b. The processor 100a realizes each function of the elevator system 1 by reading out and executing a program stored in the memory 100b.

The processor 100a is also called a CPU (Central Processing Unit), a Processing device, an arithmetic device, a microprocessor, a microcomputer, or a DSP. The memory 100b is constituted by a nonvolatile or nonvolatile semiconductor memory such as a RAM, a ROM, a flash memory, an EPROM, and an EEPROM.

In the case where the processing circuit includes the dedicated hardware 200, the processing circuit is realized by, for example, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination thereof.

The functions of the elevator system 1 can be implemented by the processing circuit separately. Alternatively, the functions of the elevator system 1 can be realized by the processing circuit in a unified manner. For each function of the elevator system 1, a part may be implemented by dedicated hardware 200 and the other part may be implemented by software or firmware. In this way the processing circuit realizes the functions of the elevator system 1 by means of dedicated hardware 200, software, firmware or a combination thereof.
