Embodiment 1

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

The elevator system 1 is applied to a building. The building has a plurality of floors. In this example, the building is divided into a plurality of areas. In this example, each area is included in an arbitrary floor. In a building, at least a portion of the area is allocated to tenants hosting the building. The tenant is, for example, a store or office that enters a building in a short time such as a day or an hour. Alternatively, the tenant may be a merchant or the like that uses a part of the area allocated to the tenant by the user for a job or the like of the user in a short time such as a unit of one day or a unit of hour. Alternatively, the tenant may be an office (Non-Territorial Office, open office) or the like using a free address of a seat of a worker who does not fix the worker. The tenant is, for example, a shared office space, a leasing office, a shared office, or a fee-based exercise room, etc. Multiple regions may also be allocated to one tenant. In this case, part or all of the plurality of areas may be included in different floors. In this example, 1 floor of the building includes 1 zone.

A hoistway, not shown, is provided in a building. The hoistway is a vertically long space extending over a plurality of floors. A landing, not shown, is provided on each floor of the building. The landing is a place adjacent to the hoistway.

In this example, a user of the elevator system 1 holds the portable terminal 2. The mobile terminal 2 is a portable information terminal equipped with a wireless communication function. The mobile terminal 2 is, for example, a smart phone. The mobile terminal 2 has a function of presenting information received by wireless communication to a user. The mobile terminal 2 presents information to the user by displaying a screen, for example. Alternatively, the mobile terminal 2 may present information to the user by voice, for example. The wireless communication function mounted on the mobile terminal 2 may be, for example, direct communication with other devices through short-range wireless communication or the like, or may be communication with other devices through a wide area communication network such as the internet.

The elevator system 1 includes one or more elevators 3, one or more call registration devices 4, and a group control device 5. In this example, the elevator system 1 includes a plurality of elevators 3 and a plurality of call registration devices 4.

Each elevator 3 includes a hoisting machine 6, a car 7, and a control panel 8. The hoisting machine 6 is a device that generates driving force. The car 7 is a device that travels in a hoistway by a driving force generated by the hoisting machine 6, and conveys users and the like between a plurality of floors. When the car 7 stops at any floor, the user gets into the car 7 from the landing at that floor or gets out of the car 7 to the landing at that floor. The car 7 is provided with a car door 9. The car door 9 is the following device: when the car 7 stops at any floor, the elevator can be opened and closed so that a user can get in the car 7 from the landing at that floor or get out of the car 7 to the landing at that floor. The car 7 is provided with a scale 10. The scale 10 is a device for measuring the load of the car 7. The car 7 is set with a maximum bearing weight. The control panel 8 is a part for controlling the operation such as the running of the car 7. The control panel 8 controls the operation of the car 7, including departure, acceleration, deceleration, and stopping of the car 7, and opening and closing of the car door 9. The control panel 8 obtains a measurement value of the load weight of the car 7 measured by the scale 10.

The call registration device 4 is a device that receives a call registration operation performed by a user. The call registration device 4 receives, for example, an operation of a hall call. At this time, the call registration device 4 is disposed at each floor landing. The landing call at a certain floor is operated by, for example, a user who rides on the car 7 of the arbitrary elevator 3 from the floor. The call registration device 4 receives, for example, an operation of a car call. At this time, the call registration device 4 is disposed inside the car 7 of each elevator 3. The operation of the car call in a certain car 7 is performed, for example, so that the destination floor of the user can be designated by the user who has entered the car 7.

The group control device 5 is a device that manages the operation of the elevator 3 in the elevator system 1. The group control device 5 is disposed in a building. The group control device 5 includes a control unit 11, a storage unit 12, an estimation unit 13, a summation unit 14, a prediction unit 15, and a presentation unit 16.

The control unit 11 is a part on which functions for acquiring and controlling the states of the elevators 3 are mounted. The status information of the elevator 3 acquired by the control unit 11 includes call information on the elevator 3, status information of the car 7 of the elevator 3, and the like. The status information of the car 7 includes information such as a measured value of the load weight measured by the scale 10 of the car 7. The status information of the elevator 3 controlled by the control unit 11 includes call assignment and the like related to the elevator 3. The control unit 11 is connected to the control panel 8 of each elevator 3. The control unit 11 manages the operation plans of the respective elevators 3 by call allocation or the like. The control panel 8 of each elevator 3 controls the operation of the elevator 3 such as the running of the car 7 in accordance with the operation plan of the control unit 11.

The storage unit 12 is a part on which a function of storing information is mounted. The storage unit 12 stores tenant identification information for identifying a tenant who has entered a building in association with area information of an area allocated to the tenant. The area information of an area includes information of a rated number of persons set for the area and which floor the area is included on.

The estimating unit 13 is a part equipped with a function of estimating the number of passengers in the car 7 of each elevator 3. The estimating unit 13 estimates the number of passengers based on the state of the elevator 3 acquired by the control unit 11. The estimating unit 13 estimates the number of passengers on the car 7 at an arbitrary floor, for example, based on information on a change in a measured value of a scale 10 provided to the car 7 when the car 7 stops at the floor.

The aggregation unit 14 is a unit that has a function of aggregating the number of users who are using the area allocated to the tenant. The totaling unit 14 counts the number of passengers based on the number of passengers of the cars 7 of each elevator 3 estimated by the estimating unit 13, for example.

The prediction unit 15 is a part on which a function of predicting whether the area allocated to the tenant can be used is mounted. The prediction unit 15 predicts availability of the user who takes the tenant as a destination and rides the car 7 of the arbitrary elevator 3. The prediction unit 15 predicts availability based on the number of passengers estimated by the estimation unit 13, the number of users counted by the counting unit 14, and the information stored in the storage unit 12.

The presentation unit 16 is a part having a function of presenting the floor of the available area to the user of the car 7. The presentation by the presentation unit 16 is performed, for example, in accordance with the availability predicted by the prediction unit 15. The presentation by the presentation unit 16 is performed by, for example, the portable terminal 2 held by the user. The presentation unit 16 presents information to the user by transmitting floor information of the available area to the mobile terminal 2 by wireless communication, for example. The presentation unit 16 transmits information to the mobile terminal 2 by direct wireless communication, for example. In this case, the presentation unit 16 is, for example, a hall where the user is waiting, or a wireless beacon disposed in the car 7 where the user sits. Alternatively, the presentation unit 16 may transmit information to the mobile terminal 2 via a wide area communication network such as the internet. At this time, the mobile terminal 2 recognizes the hall where the user is located or the car 7 where the user is located from a wireless signal transmitted from a hall where the user is waiting or a wireless beacon or the like arranged in the car 7 where the user is located. The mobile terminal 2 may select information to be presented to the user, for example, based on the identified hall or car 7. Alternatively, the presentation unit 16 may present information to the user by, for example, notifying floor information of the available area by a notification device, not shown. In this case, the notification device is disposed, for example, at a hall where the user is waiting or at a car 7 where the user sits. The notification device performs notification by displaying visual information such as a display or audible information such as voice.

Fig. 2 is a front view of the call registration device 4 according to embodiment 1.

Fig. 2 shows an example of the call registration device 4 which is disposed in a hall and receives an operation of a hall call.

The call registration device 4 includes a button unit 17a and a display 18. The button unit 17a includes an up button and a down button. The up button is a button for receiving an operation of a hall call by a user who is going to move to an upper floor. The down button is a button for receiving an operation of a hall call by a user who is going to move to a floor below. The display 18 is a part for presenting information to a user at the landing by displaying. The display 18 displays, for example, information such as the current position of the car 7 or the traveling direction of the car 7. Here, the call registration device 4 may be provided with a lamp or a speaker instead of the display 18, or may be provided with a lamp or a speaker together with the display 18. The call registration device 4 may also serve as a notification device.

Fig. 3 is a diagram showing an example of the hardware configuration of the control panel 8 according to embodiment 1.

The functions of the control panel 8 may be implemented by a processing circuit. The processing circuit is provided with at least 1 processor 8a and at least 1 memory 8b. The processing circuit may include at least one piece of dedicated hardware in addition to the processor 8a and the memory 8b, or may include at least one piece of dedicated hardware instead of the processor 8a and the memory 8b.

In the case where the processing circuit includes the processor 8a and the memory 8b, each function of the control panel 8 is realized 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 8 b. The processor 8a realizes the functions of the control panel 8 by reading out and executing programs stored in the memory 8 b.

The processor 8a is also called a CPU (Central Processing Unit: central processing unit), a processing device, an arithmetic device, a microprocessor, a microcomputer, or a DSP. The Memory 8b is constituted by a nonvolatile or volatile semiconductor Memory such as RAM (Random Access Memory: random access Memory), ROM (Read Only Memory), flash Memory, EPROM (Erasable Programmable Read Only Memory: erasable programmable Read Only Memory), EEPROM (Electrically Erasable Programmable Read Only Memory: electrically erasable programmable Read Only Memory), or the like.

In the case of processing circuitry having dedicated hardware, the processing circuitry is implemented, for example, by a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC (Application Specific Integrated Circuit: application specific integrated circuit), an FPGA (Field Programmable Gate Array: field programmable gate array), or a combination thereof.

The functions of the control panel 8 can be realized by a processing circuit, respectively. Alternatively, the functions of the control panel 8 can be realized by a processing circuit. With respect to the functions of the control panel 8, one part may be implemented by dedicated hardware, and the other part may be implemented by software or firmware. Thus, the processing circuitry implements the functions of the control disk 8 by dedicated hardware, software, firmware, or a combination thereof.

Fig. 4 is a diagram showing an example of the hardware configuration of the group control device 5 according to embodiment 1.

The functions of the group control device 5 can be realized by a processing circuit. The processing circuit is provided with at least 1 processor 5a, at least 1 memory 5b and a clock 5c. The processing circuit may further include at least 1 piece of dedicated hardware, while the processing circuit includes the processor 5a, the memory 5b, and the clock 5c, or may include at least 1 piece of dedicated hardware instead of the processor 5a, the memory 5b, and the clock 5c.

In the case where the processing circuit includes the processor 5a and the memory 5b, each function of the group control device 5 is realized 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 5 b. The processor 5a reads out and executes a program stored in the memory 5b to realize each function of the group control device 5. When the processing circuit includes the clock 5c, the function requiring time information among the functions of the group control device 5 is realized by a combination of software, firmware, or the like and the clock 5c.

The processor 5a is also called a CPU, a processing device, an arithmetic device, a microprocessor, a microcomputer, a DSP. The memory 5b is constituted by a nonvolatile or nonvolatile semiconductor memory such as RAM, ROM, flash memory, EPROM, EEPROM, or the like, for example.

In the case of processing circuitry provided with dedicated hardware, the processing circuitry is implemented, for example, by 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 group control device 5 can be realized by a processing circuit. Alternatively, the functions of the group control device 5 may be realized by a processing circuit. The functions of the group control device 5 may be implemented in part by dedicated hardware, and the other parts may be implemented in software or firmware. Thus, the processing circuit implements the functions of the group management device 5 by dedicated hardware, software, firmware, or a combination thereof.

Next, an example of presenting information to a user in the elevator system 1 will be described with reference to fig. 5 to 9.

Fig. 5 to 8 are diagrams showing examples of data handled in the elevator system 1 of embodiment 1.

Fig. 5 shows an example of information stored in the storage unit 12. The storage unit 12 stores tenant identification information in association with area information. The storage unit 12 may store the same tenant identification information in association with a plurality of pieces of area information. In this example, the area information of the area includes: information including the floor of the area, the rated number of people set for the area, and the utilization time set for the area.

Fig. 6 shows an example of the number of passengers estimated by the estimating unit 13. When the call registration device 4 receives an operation of a hall call at an arbitrary floor, the estimating unit 13 acquires information of the hall call from the control unit 11. At this time, the estimating unit 13 generates a boarding pass table. The data shown in fig. 6 is an example of a passenger count table. The boarding and disembarking person table is a table for managing information of the boarding and disembarking person estimated by the estimating unit 13. The number of passengers includes the number of passengers and the number of passengers getting off the stairs. The estimating unit 13 estimates the number of passengers, for example, as follows.

In this example, the operation of the landing call is performed at the landing of layer 1. At floor 1, a plurality of users including users who have performed a landing call wait for an arbitrary car 7 to arrive. Then, the control unit 11 assigns the hall call to any elevator 3. The control panel 8 of the elevator 3 to which the hall call is assigned moves the car 7 to the floor 1.

In this example, car 7 is at time 9:00:00 is parked at level 1, the car door 9 is opened. In this example, no user is descending from the car 7 at the landing of floor 1. Therefore, the weight scale 10 does not measure a decrease in the load weight associated with the user getting off the elevator. A user waiting for the arrival of the car 7 at the landing of the 1 st floor rides on the car 7 with the car door 9 opened. At this time, the weight scale 10 measures an increase in the load weight with the riding of the user. In this example, the scale 10 measures a 50% increase in the maximum load bearing weight of the car 7. The change in the load weight measured by the scale 10 is recorded in the passenger/landing person table. The user who has landed on the car 7 performs an operation of registering a car call of a destination floor using the call registration device 4 provided inside the car 7. In this example, a user who is a tenant of tenant identification information "00001" performs an operation of a car call of 5 floors as a destination floor. Further, the user who is the destination of the tenant identification information "00002" performs an operation of a car call having 10 floors as the destination floor. The control panel 8 controls the operation of the car 7 so that it travels to the registered destination floor and stops. The car 7 closes the car door 9 and starts from the floor 1 upward.

The estimating unit 13 estimates the number of passengers on the car 7 at the floor 1 from the number of passengers corresponding to the maximum load weight of the car 7. In this example, the maximum load weight of the car 7 corresponds to the weight of 20 users. Since the balance 10 does not measure the decrease in the load weight after the car door 9 is opened at the level 1, the estimating section 13 estimates the number of passengers getting off at the level 1 as 0. On the other hand, since the scale 10 measures a 50% increase in the maximum load weight before the car door 9 is closed at the level 1, the estimating unit 13 estimates the number of passengers at the level 1 as 10. The number of passengers at level 1 estimated by the estimating unit 13 is recorded in the passenger number table.

Then, the car 7 at time 9:00:30 are parked at 5 floors, the car door 9 is opened. A user who is a destination of tenant identification information "00001" steps down from car 7 with car door 9 opened to a landing of 5 floors. At this time, the weight scale 10 measures a decrease in the load weight as the user gets off the elevator. In this example, the balance 10 measures a 25% reduction in the maximum load bearing weight of the car 7. On the other hand, no user is riding the car 7 from the landing of 5 floors. Therefore, the scale 10 does not measure an increase in the load weight associated with the riding of the user. Then, the car 7 closes the car door 9, and starts from the 5 floors upward.

The estimating unit 13 estimates the number of passengers on the car 7 at the 5 floors from the number of passengers corresponding to the maximum load weight of the car 7. Since the balance 10 measures a 25% reduction in the maximum load weight after the car door 9 is opened at 5 floors, the estimating section 13 estimates the number of passengers getting off at 5 floors as 5. On the other hand, the scale 10 does not measure an increase in the load weight before the car door 9 is closed at 5 floors, and therefore the estimating section 13 estimates the number of passengers at 5 floors as 0.

Then, the car 7 at time 9:01:00 is parked at 10 floors, the car door 9 is opened. A user who is a destination of tenant identification information "00002" gets off from car 7 with car door 9 opened at a landing of 10 floors. At this time, the weight scale 10 measures a decrease in the load weight as the user gets off the elevator. In this example, the balance 10 measures a 25% reduction in the maximum load bearing weight of the car 7. Then, the user waiting for the arrival of the car 7 at the landing of 10 floors rides on the car 7 with the car door 9 opened. At this time, the weight scale 10 measures an increase in the load weight with the riding of the user. In this example, the scale 10 measures a 10% increase in the maximum load bearing weight of the car 7. Then, the car 7 closes the car door 9, starting from the 10 floors.

The estimating unit 13 estimates the number of passengers on the car 7 at the 10 floors from the number of passengers corresponding to the maximum load weight of the car 7. Since the balance 10 measures a 25% decrease in the maximum load weight after the car door 9 is opened at 10 floors, the estimating unit 13 estimates the number of passengers getting off at 10 floors as 5. Further, since the scale 10 measures a 10% increase in the maximum bearing weight before the car door 9 is closed at the 10 floors, the estimating section 13 estimates the number of passengers at the 10 floors as 2.

Fig. 7 shows an example of the total number of users by the total unit 14. The summing unit 14 generates a utility model. The data shown in fig. 7 is an example using a human figure. The usage person table is a table for managing information on the number of users in each area counted by the counting unit 14. The totaling unit 14 counts the number of users, for example, as follows.

The totaling unit 14 counts the number of the passengers based on the number of the passengers estimated by the estimating unit 13, for example. For example, when a user who has stepped off from the car 7 exists at an arbitrary floor, the totaling unit 14 considers that the user uses the area included in the floor after the user has stepped off, and adds the area to the number of users. For example, when a user who has landed on the car 7 is present at an arbitrary floor, the totaling unit 14 considers that the user has finished using the area included in the floor and subtracts the area from the number of users. The number of users counted by the counting unit 14 is recorded in a user number table. The totaling unit 14 resets (reset) the information of the area in the usage person table, for example, when the usage time of the area ends.

Fig. 8 shows an example of the availability prediction by the prediction unit 15. The prediction unit 15 generates a availability table. The data shown in fig. 8 is an example of a availability table. The availability table is a table for managing information of availability of each area predicted by the prediction unit 15. The prediction unit 15 predicts availability as follows, for example.

The predicting unit 15 calculates the number of persons available from this point on for each area by subtracting the number of persons used in the area, which is counted up by the counting unit 14, from the rated number of persons in the area, which is stored as area information in the storing unit 12. The predicting unit 15 predicts that the user of the car 7 cannot use the area from the time when the number of passengers on a floor is equal to or greater than the available number of passengers in the area included in the floor, based on the number of passengers estimated by the estimating unit 13, which has not been counted up by the counting up unit 14. On the other hand, when the number of persons getting off a floor is lower than the available number of persons in the area included in the floor, the prediction unit 15 predicts that the area is available to the user who has taken the car 7 from the beginning.

The presentation unit 16 presents the prediction result of availability by the prediction unit 15 to the user of the car 7 from that point forward. The presentation unit 16 presents, for example, the floor of each area and availability of the area. The presentation unit 16 may present the available number of people for the available area.

Next, an operation example of the elevator system 1 will be described with reference to fig. 9.

Fig. 9 is a flowchart showing an example of the operation of the elevator system 1 according to embodiment 1.

In step S101, the control unit 11 determines whether or not a landing call is operated on an arbitrary floor. If the determination result is no, the process of the elevator system 1 related to the information presentation to the user ends. If the determination result is yes, the control unit 11 assigns a hall call to any car 7. Then, the process of the elevator system 1 proceeds to step S102.

In step S102, the estimating unit 13 obtains a change in the load weight measured by the scale 10 at the stop floor of the car 7 to which the hall call is assigned. Then, the process of the elevator system 1 proceeds to step S103.

In step S103, the control unit 11 determines whether or not the cars 7 to which the hall call is assigned respond to all the registered car calls. If the determination result is no, the process of the elevator system 1 proceeds to step S102. If the determination result is yes, the process of the elevator system 1 proceeds to step S104.

In step S104, the estimating unit 13 estimates the number of passengers on the car 7 to which the hall call is assigned, based on the change in the load weight measured by the scale 10. Then, the process of the elevator system 1 proceeds to step S105.

In step S105, the predicting unit 15 calculates the available number of persons for each area based on the number of persons thus far counted by the counting unit 14 and the area information stored in the storage unit 12. The prediction unit 15 predicts whether or not each area is available based on the calculated available number of persons and the number of passengers of the car 7 estimated by the estimation unit 13. Then, the process of the elevator system 1 proceeds to step S106.

In step S106, the presentation unit 16 presents the prediction result of availability by the prediction unit 15 to the user of the car 7 from that point forward. At this time, the presentation unit 16 presents information to the user waiting for the car 7 at the landing, for example. Alternatively, the presentation unit 16 may present information to the user in the car 7 when the user gets on the car 7 from a landing. Then, the process of the elevator system 1 related to the information presentation to the user ends.

As described above, the elevator system 1 according to embodiment 1 includes the control unit 11, the storage unit 12, the estimation unit 13, the prediction unit 15, and the presentation unit 16. The control unit 11 acquires and controls the state of the elevator 3. The elevator 3 is provided in a building having a plurality of floors. The storage unit 12 stores tenant identification information for identifying a tenant in association with the area information. The tenant identification information is used to identify a tenant assigned with at least a partial area of a building. The area information includes rated persons of an area allocated to the tenant and floor information of the area. The estimating unit 13 estimates the number of passengers in the car 7 of the elevator 3 based on the state of the elevator 3 acquired by the control unit 11. The totalizing unit 14 totals the number of users assigned to the area of the tenant. The prediction unit 15 predicts whether or not the area allocated to the tenant can be used, based on the number of passengers estimated by the estimation unit 13, the number of users counted by the counting unit 14, and the information stored in the storage unit 12. The presentation unit 16 presents the floor of the available area to the user of the car 7 based on the availability predicted by the prediction unit 15.

According to this configuration, the floor of the available area is presented to the user, and thus the situation of the destination can be easily grasped. This can suppress occurrence of a situation in which the user is not able to use the elevator 3 after the user moves to the destination, and thus can suppress a decrease in the operation efficiency caused by the user moving again using the elevator 3. Further, the user can grasp the available area in advance, and therefore, it is possible to suppress a situation in which 1 user inputs a plurality of floors including an area of unclear availability as destination floors. This can suppress wasteful call registration, and therefore can suppress a decrease in the operation efficiency of the elevator system 1. Further, since the available area can be grasped according to the condition of the destination, the convenience of the user can be further improved.

The presentation unit 16 presents the available floors by the portable terminal 2 held by the user.

According to this configuration, the user can grasp availability by the portable terminal 2 held by the user, and thus the user's convenience can be further improved.

The estimating unit 13 estimates the number of passengers on the car 7 based on the measurement value change information of the scale 10 for measuring the load weight of the car 7.

According to this configuration, the number of passengers is estimated from the measurement value of the scale 10 mounted on the car 7 of the elevator 3, and thus the elevator system 1 can be more easily constructed.

In addition, when a plurality of areas allocated to different tenants are included in 1 floor, the totalizing unit 14 may estimate which area the user descending on the floor uses and total the areas. The totalizing unit 14 may count, for example, the number of people who have taken off the floor and multiplied by the ratio corresponding to the tenant as the number of people who use the tenant. The proportion corresponding to the tenant is, for example, a proportion corresponding to the area of the floor, the rated number of people, or the like. As a more specific example, the aggregation unit 14 may be configured to consider that 1 person uses the former region and 2 persons use the latter region to aggregate when 3 persons get off a floor including the 10 rated number of persons and the 20 rated number of persons.

The estimating unit 13 may estimate the number of passengers on the car 7 based on the number of hall calls assigned to the car 7 by the control unit 11 and the number of car calls registered from the car 7. When each user performs a landing call and a car call, the number of these calls corresponds to the number of people who have landed on and off the car 7. Therefore, the estimating unit 13 can estimate the number of passengers based on the number of calls. The estimating unit 13 estimates the number of passengers on a landing at an arbitrary floor, for example, from the number of landing calls on the landing. The estimating unit 13 estimates the number of passengers getting off the elevator at an arbitrary floor, for example, from the number of car calls at the floor.

Embodiment 2

In embodiment 2, differences from the example disclosed in embodiment 1 will be described in particular detail. As for the features not described in embodiment 2, any of the features disclosed in the example of embodiment 1 may be employed.

In this example, the call registration device 4 receives an operation of identifying a destination call at a departure floor and a destination floor. At this time, the call registration device 4 is disposed at a hall, for example. The destination call is performed by a user who rides on the car 7 of the elevator 3 from a hall floor, for example. In the operation of the destination call, the user inputs the destination floor. In this way, the hall floor where the call registration device 4 is provided is specified as the departure floor of the destination call, and the floor input by the user is specified as the destination floor of the destination call. The call registration device 4 may be disposed at a landing of each floor.

The control unit 11 assigns a destination call, which the call registration device 4 has received an operation, to an arbitrary car 7. The control panel 8 of the elevator 3 to which the destination call is assigned causes the car 7 to travel to the departure floor of the destination call.

Fig. 10 is a front view of the call registration device 4 according to embodiment 2.

The call registration device 4 includes a number key unit 17b and a display 18. The number key unit 17b includes a plurality of number buttons in a manner that enables the user to input a destination floor. The display 18 displays, for example, information for specifying the elevator 3 to which the destination call is assigned by the control unit 11, to the user who has performed the destination call operation. In this example, elevator 3 of machine a to which a hall call is assigned is displayed to the user.

Fig. 11 is a diagram showing an example of data processed in the elevator system 1 of embodiment 2.

Fig. 11 shows an example of the estimation of the number of passengers by the estimating unit 13. When the call registration device 4 receives an operation of a destination call, the estimating unit 13 acquires information of the destination call from the control unit 11. At this time, the estimating unit 13 generates a boarding and disembarking person table based on the destination call. The data shown in fig. 11 is an example of a boarding and disembarking person table based on a destination call. The estimating unit 13 estimates the number of passengers, for example, as follows.

In this example, the call registration device 4 for the hall arranged in the layer 1 is configured to perform the following processing until time 9:00: up to 00, 5 users each perform an operation of a destination call having 5 floors as destination floors. Further, the call registration device 4 for the hall arranged in the layer 1 reaches the time 9:00: up to 00, 5 users each perform an operation of a destination call having 10 floors as destination floors. Further, the call registration device 4 for the hall arranged at the 10 th floor reaches the time 9:01: up to 00, 1 user performs an operation of a destination call having 1 floor as a destination floor. The control unit 11 assigns these destination calls to the elevator 3 of the machine a. The control panel 8 of the elevator 3 of machine a drives the car 7 to floor 1.

The estimating unit 13 estimates the number of passengers on each floor of the car 7 of the car a based on the number of destination calls allocated to the elevator 3 of the car a. The estimating unit 13 estimates the number of passengers as if each user has performed the destination call operation. When each user performs an operation of a destination call, the number of destination calls corresponds to the number of people who have landed on the car 7. The estimating unit 13 estimates the number of passengers at the floor 1 as 10 based on the number of destination calls having the floor 1 assigned to the machine a as the departure floor. Further, the estimating unit 13 estimates the number of passengers at 5 floors as 5 persons based on the number of destination calls assigned to the machine a and having 5 floors as destination floors. Further, the estimating unit 13 estimates the number of passengers getting off at 10 floors as 5 persons based on the number of destination calls allocated to the machine a and having 10 floors as destination floors. The number of passengers on each floor estimated by the estimating unit 13 is recorded in the passenger number table.

The totaling unit 14 counts the number of the passengers based on the number of the passengers estimated by the estimating unit 13, for example. For example, when a user who has stepped off from the car 7 exists at an arbitrary floor, the totaling unit 14 considers that the user uses the area included in the floor after the user has stepped off and adds the area to the number of users. When a user who is to sit on the car 7 is present on an arbitrary floor, for example, the totaling unit 14 considers that the user finishes using the area included in the floor and subtracts the area from the number of users. The number of users counted by the counting unit 14 is recorded in a user number table. The totaling unit 14 resets the information of the area in the usage person table, for example, when the usage time of the area ends.

The predicting unit 15 calculates the number of persons available from this point on for each area by subtracting the number of persons used in the area, which is counted up by the counting unit 14, from the rated number of persons in the area, which is stored as area information in the storing unit 12. The predicting unit 15 predicts that the user who is to take the car 7 cannot use the area from the time when the number of passengers on a floor is equal to or greater than the available number of passengers in the area included in the floor, based on the number of passengers estimated by the estimating unit 13, which has not been counted up by the counting up unit 14. On the other hand, when the number of persons getting off a floor is lower than the available number of persons in the area included in the floor, the prediction unit 15 predicts that the area is available to the user who is to take the car 7 from this point on.

The presentation unit 16 presents the prediction result of availability by the prediction unit 15 to the user who is to ride the car 7 from this point forward. The presentation unit 16 presents, for example, the floor of each area and availability of the area. The presentation unit 16 may present the number of available persons for the available area. The presenting unit 16 may present the prediction result of availability to the user using the display 18 of the call registration device 4 as a notifying device. The presentation unit 16 may present a presentation for prompting the user who has input the unavailable destination floor to input the destination floor again.

As described above, the estimating unit 13 of the elevator system 1 according to embodiment 2 estimates the number of passengers in the car 7 based on the number of destination calls assigned to the car 7 by the control unit 11. The destination call is a call that determines the departure floor and the destination floor.

Generally, the operation of the destination call is performed by each user. Therefore, the number of passengers can be estimated with higher accuracy from the number of users and the number of corresponding destination calls.

The estimating unit 13 may combine the estimation of the number of passengers based on the change in the measurement value of the scale 10 with the estimation of the number of passengers based on the number of destination calls. The estimating unit 13 may estimate the number of passengers at the floor where the hall is provided with the call registration device 4 that receives the destination call, for example, based on the number of destination calls, and estimate the number of passengers at the floor where the hall is provided with the call registration device 4 that receives the hall call for which the destination call is not specified, based on the change in the measurement value of the scale 10.

The destination call may be performed by, for example, the portable terminal 2 held by the user. For example, when registering a destination call, the user inputs both the departure floor and the destination floor to the mobile terminal 2. The departure floor and the destination floor may be set in advance in the mobile terminal 2 by a user or the like, for example. The mobile terminal 2 transmits information of the destination call to the control unit 11 via a wide area communication network such as the internet, for example.

Embodiment 3

In embodiment 3, differences from the examples disclosed in embodiment 1 or embodiment 2 will be described in particular detail. As for the features not described in embodiment 3, any of the features disclosed in the examples of embodiment 1 or embodiment 2 may be employed.

Fig. 12 is a structural diagram of an elevator system 1 according to embodiment 3.

In a building to which the elevator system 1 is applied, an entry and exit management device 19 is provided. The entry and exit management device 19 is a device that manages entry and exit of at least any area in a building. The entry and exit management device 19 manages users who enter and exit the area in the building by user identification information for identifying the users. Here, the user identification information is information such as a number uniquely assigned to the user. In this case, the user identification information is stored in an identifier such as an IC card held by the user. Alternatively, the user identification information may be biometric information such as fingerprint information, vein information, or iris information of the user. The entry and exit management device 19 includes a reading device 20 that reads user identification information of each user. The reader 20 reads user identification information from an identification body held by a user by, for example, short-range wireless communication or the like. Alternatively, the reading device 20 may read, for example, the biometric information of the user as the user identification information.

In this example, the call registration device 4 cooperates with the reading device 20 of the entry and exit management device 19. The call registration device 4 may be integrated with the reading device 20. After the reading device 20 reads the user identification information, the call registration device 4 receives a call registration operation of the user identified based on the user identification information. The call registration device 4 receives, for example, an operation of destination call registration.

Next, an example of information presentation to the user in the elevator system 1 will be described with reference to fig. 13 and 14.

Fig. 13 and 14 are diagrams showing examples of data processed in the elevator system 1 according to embodiment 3.

Fig. 13 shows an example of information stored in the storage unit 12. The storage unit 12 stores tenant identification information in association with area information. The storage unit 12 stores area information of an area in association with tenant identification information, including information such as a floor including the area, a rated number of persons set for the area, whether or not security setting is present in the area, user identification information for identifying users who can use the area, and a use time set for the area.

Fig. 14 shows an example of the estimation of the number of passengers by the estimating unit 13. When the call registration device 4 receives an operation of a destination call, the estimating unit 13 acquires information of the destination call from the control unit 11. At this time, the estimating unit 13 generates a boarding and disembarking person table based on the destination call. The data shown in fig. 14 is an example of a boarding and disembarking person table based on a destination call. The estimating unit 13 estimates the number of passengers, for example, as follows.

In this example, the reader 20 of the layer station arranged in layer 1 is configured to read out the layer at time 9:00:00, user identification information "00001" of the user is read. At this time, the call registration device 4 receives an operation of the user to call a destination at 5 floors. The control unit 11 determines whether or not the available area of the user is located at 5 floors as destination floors. The control unit 11 determines that all users are available for the area where the security is set to "none", for example. For example, the control unit 11 determines that the user having registered the user identification information in advance is available in the area where the security setting is "present" and determines that the user having not registered the user identification information is unavailable. When it is determined that the available area of the user identification information "00001" is located at 5 floors, the control unit 11 assigns the destination call of the user to the car 7 of any elevator 3. On the other hand, when it is determined that the available area of the user is not at level 5, the control unit 11 does not assign a destination call by the user to the car 7 of the elevator 3.

The reader 20 disposed at the layer station of layer 1 is configured to read out the data at time 9:00:00, user identification information "00030" of the user is read. At this time, the call registration device 4 receives a destination call operation performed by the user and having 10 floors as destination floors. The control unit 11 determines whether or not the available area of the user is located at 10 floors as destination floors. When it is determined that the available area of the user identification information "00030" is located at 10 floors, the control unit 11 assigns the destination call of the user to the car 7 of any elevator 3. On the other hand, when it is determined that the available area of the user is not at level 10, the control unit 11 does not assign a destination call by the user to the car 7 of the elevator 3.

The reader 20 of the landing disposed at 10 layers is configured to read at the time 9:01:00, user identification information "00025" of the user is read. At this time, the call registration device 4 receives an operation of the user to call a destination call having a floor 1 as a destination floor. The control unit 11 determines whether or not the available area of the user is located at 1 floor which is the destination floor. For example, when the destination floor is a hall floor, the control unit 11 determines that all users can use the floor.

The estimating unit 13 estimates the number of passengers on each floor of the car 7 of the elevator 3 based on the number of destination calls allocated to the elevator 3. Since the operation of the destination call is performed by each user, the estimating section 13 estimates the number of passengers as if the number of destination calls corresponds to the number of passengers in the elevator car 7. The number of passengers on each floor estimated by the estimating unit 13 is recorded in the passenger number table.

The totaling unit 14 counts the number of the passengers based on the number of the passengers estimated by the estimating unit 13, for example. For example, when a user who has stepped off from the car 7 exists at an arbitrary floor, the totaling unit 14 considers that the user uses the area included in the floor after the user has stepped off and adds the area to the number of users. In this case, when the area in which the user identification information of the user is registered is located on the floor, the totaling unit 14 may be regarded as adding the user to the number of users by using the area. For example, when a user who has landed on the car 7 exists on an arbitrary floor, the totaling unit 14 considers that the user has finished using the area included in the floor and subtracts the area from the number of users. In this case, when the area in which the user identification information of the user is registered is located on the floor, the totaling unit 14 may be regarded as adding the number of users by ending the use of the area. The number of users counted by the counting unit 14 is recorded in a user number table. The totaling unit 14 resets the information of the area in the usage person table, for example, when the usage time of the area ends.

The predicting unit 15 calculates the number of persons available from this point for each area by subtracting the number of persons used in the area, which is counted up by the counting unit 14, from the rated number of persons in the area stored as the area information in the storing unit 12. The predicting unit 15 predicts that the user cannot use the area to be used by the user when the available number of users in the area to be used by the user is 0, for users whose total number of users is not counted as the number of users. On the other hand, the prediction unit 15 predicts that the user is available for the area that the aggregation unit 14 has not summed up as the user, when the available number of users in the area that the user uses is greater than 0.

The presenting unit 16 presents the prediction result of availability of the predicting unit 15 to the user who performed the destination call operation. The presentation unit 16 presents the floors of each area together with the availability of the area, for example. The presentation unit 16 may present the number of available persons for the available area. The presenting unit 16 may present the prediction result of availability to the user using the display 18 of the call registration device 4 as a notifying device. The presentation unit 16 may present a prompt for prompting the user who has input the unavailable destination floor to input the destination floor again.

Next, an operation example of the elevator system 1 will be described with reference to fig. 15.

Fig. 15 is a flowchart showing an example of the operation of elevator system 1 according to embodiment 3.

In step S201, the control unit 11 determines whether or not a user who has read user identification information by the reading device 20 of the entrance/exit management device 19 has performed an operation of a destination call. If the determination result is no, the process of the elevator system 1 related to the information presentation to the user ends. If the determination result is yes, the control unit 11 identifies the user based on the user identification information. The control unit 11 determines whether or not to restrict the allocation of the destination call of the identified user based on the user identification information and the area information stored in the storage unit 12. When determining that the assignment of the destination call is not limited, the control unit 11 assigns the destination call to any car 7. Then, the process of the elevator system 1 proceeds to step S202.

In step S202, the estimating unit 13 acquires information of a destination call assigned to the car 7 of the elevator 3. Then, the process of the elevator system 1 proceeds to step S203.

In step S203, the estimating unit 13 estimates the number of passengers in the car 7 of the elevator 3 from the departure floor and the destination floor of the destination call for each user. Then, the process of the elevator system 1 proceeds to step S204.

In step S204, the predicting unit 15 calculates the number of available persons for each area based on the number of persons to be used thus far counted by the counting unit 14 and the area information stored in the storage unit 12. The prediction unit 15 predicts whether or not each area is available based on the calculated available number of persons and the number of passengers of the car 7 estimated by the estimation unit 13. Then, the process of the elevator system 1 proceeds to step S205.

In step S205, the presentation unit 16 presents the prediction result of availability of the prediction unit 15 to the user who has to ride the car 7 since that time. At this time, the presentation unit 16 presents information to the user who has performed the operation of the destination call, for example. Then, the process of the elevator system 1 related to the information presentation to the user ends.

As described above, the elevator system 1 according to embodiment 3 obtains user identification information for identifying users who enter and exit the area allocated to the tenant from the entry/exit management device 19. The entry and exit management device 19 manages entry and exit of users into and from areas allocated to tenants.

The totalizing unit 14 uses the number of persons entering and exiting the area based on the information acquired from the entrance/exit management device 19 to total the number of persons using the area. The number of passengers in and out of the area is estimated by the estimating unit 13 as, for example, the number of passengers on the car 7 at the floor including the area.

According to this configuration, the number of users in the area is counted up in accordance with the number of users. This enables the number of users to be counted up with higher accuracy.

The storage unit 12 also stores tenant identification information of a tenant in association with user identification information identifying a user who can use the tenant. The control unit 11 identifies the user who is to take the car 7 by performing call registration based on the user identification information acquired from the entrance/exit management device 19. The control unit 11 restricts distribution of the call to the car 7 when the user identification information of the user who performs the call registration is not information identifying the user who can use the tenant.

According to this configuration, even if the user inputs a floor where there is no available area as a call destination floor, the call is not registered, and thus the security of the building can be further improved.

The prediction unit 15 also recognizes a user who performs call registration and who is to ride the car 7, based on the user identification information acquired from the entrance/exit management device 19. The prediction unit 15 predicts whether or not the area allocated to the tenant is available for each user based on the user identification information.

By performing the determination for each user in this manner, it is possible to determine whether or not the use is possible with higher accuracy.

The control unit 11 may restrict the following calls to be assigned to the car 7: the call is a call having a floor that does not include the area predicted to be available by the prediction unit 15 as a destination floor. For example, even if a call made by a user having registered user identification information for a certain area and having a floor including the area as a destination floor is made, the control unit 11 does not assign the call when the prediction unit 15 predicts that the area is unavailable based on the number of users or the like for the user.

According to such a configuration, even a user who can use the destination area in terms of safety can restrict movement of the destination area according to the condition of the destination. Thus, the user will utilize the other areas available. Thereby, each area in the building can be uniformly utilized.

The presenting unit 16 may present the floor of the recommended area among the areas available for the user to take the car 7 by performing call registration based on the number of passengers estimated by the estimating unit 13, the number of users counted by the counting unit 14, and the information stored in the storage unit 12. For example, when a plurality of areas on different floors are allocated to one tenant, the presentation unit 16 may present the area where the margin of the number of available people is the largest as the recommended area to the user who wants to use the tenant.

According to this configuration, the user can more smoothly specify the destination floor by referring to the recommendation of the presenting unit 16.

The control unit 11 may automatically register a call having the floor of the area recommended by the presenting unit 16 as the destination floor. The control unit 11 may register a destination call in which the floor of the area recommended by the presentation unit 16 is the destination floor, for example, without waiting for the user to input the destination floor. The control unit 11 assigns the registered destination call to the car 7 of any elevator 3.

According to this configuration, the user can use each area in the building uniformly without having to use the effort to select the destination floor. This allows the user to avoid unnecessary congestion and the like, thereby further improving convenience.

Embodiment 4

In embodiment 4, differences from the examples disclosed in embodiment 1 to embodiment 3 will be described in particular detail. As for the features not described in embodiment 4, any of the features disclosed in the examples of embodiment 1 to embodiment 3 may be employed.

Fig. 16 is a structural diagram of an elevator system 1 according to embodiment 4.

A monitoring device 21 is provided in a building to which the elevator system 1 is applied. The monitoring device 21 is a device for monitoring the condition of a building. In this example, the monitoring device 21 includes an imaging device 22 that photographs the interior of a building. The imaging device 22 is disposed, for example, in a place such as a landing where the elevator 3 can be imaged. At this time, the monitoring device 21 determines the number of users who have taken up and down the car 7 of the elevator 3 based on the image captured by the imaging device 22. The monitoring device 21 outputs the number of passengers determined from the image as correction information to the estimating unit 13 of the group control device 5.

In this example, the storage unit 12 updates the area information stored in association with the tenant identification information based on information input from outside the group control device 5. The information input from the outside of the group control device 5 is, for example, a setting change of parameters of the elevator 3. Alternatively, the information inputted from the outside of the group control device 5 is a signal inputted through the monitoring device 21, or the like. Such information is input from outside the group control device 5 through a terminal device or the like connected to a wide area communication network such as the internet, for example, by a manager of a building or the like.

Next, an operation example of the elevator system 1 will be described with reference to fig. 17.

Fig. 17 is a flowchart showing an example of the operation of elevator system 1 according to embodiment 4.

In the elevator system 1 of embodiment 4, in steps S301 to S304, the same operation as in steps S101 to S104 of the elevator system 1 of embodiment 1 is performed. After the estimating unit 13 estimates the number of passengers, the process of the elevator system 1 of embodiment 4 proceeds to step S305. Alternatively, the elevator system 1 of embodiment 4 may operate in the same manner as step S201 to step S203 of the elevator system 1 of embodiment 3 instead of step S301 to step S304, or may operate in the same manner as step S201 to step S203 of the elevator system 1 of embodiment 3 in parallel with step S301 to step S304. After the estimating unit 13 estimates the number of passengers, the process of the elevator system 1 of embodiment 4 proceeds to step S305.

In step S305, the estimating unit 13 determines whether or not correction information has been acquired from the monitoring device 21. If the determination result is yes, the process of the elevator system 1 proceeds to step S306. If the determination result is no, the process of the elevator system 1 proceeds to step S307.

In step S306, the estimating unit 13 corrects the estimated number of passengers based on the correction information. For example, the estimation of the number of passengers by the estimating unit 13 may be erroneous due to a difference in weight of each user, a weight of the load carried by the user, or the like. Alternatively, when there is a user who is co-located with another user who is to be moved to the same destination without performing a destination call operation or the like, an error may occur in the estimation of the number of passengers by the estimating unit 13. In this case, the estimating unit 13 corrects the number of passengers based on the number of passengers included in the correction information. Then, the process of the elevator system 1 advances to step S307.

In step S307 to step S308, the elevator system 1 of embodiment 4 operates in the same manner as in step S105 to step S106 of the elevator system 1 of embodiment 1. Alternatively, the elevator system 1 of embodiment 4 may operate in the same manner as in steps S204 to S205 of the elevator system 1 of embodiment 3 instead of steps S307 to S308.

As described above, the storage unit 12 of the elevator system 1 according to embodiment 4 updates the area information stored in association with the tenant identification information based on the information input from the outside. The information inputted from the outside is at least one of a signal inputted by the monitoring device 21 for monitoring the condition of the building and a change in the parameter setting of the elevator 3.

With such a configuration, the area allocation to the tenant can be easily changed. For example, when the area allocation of the building to the tenant is made in a short time such as in a unit of one day or in a unit of hour, the update such as the change or cancellation of the allocation can be more easily performed.
