DETAILED DESCRIPTION

[0030] The embodiments of the present invention will be described with reference to the accompanying drawings. In the figures, identical or corresponding parts are denoted by the same reference numerals, and repeated descriptions are simplified or omitted as appropriate. The present invention is not limited to the following embodiments, and any component of the embodiments may be modified or omitted without departing from the spirit of the present invention.

[0031] Implementation Method 1

[0032] Figure 1 This is a configuration diagram of the elevator system 1 according to the first embodiment.

[0033] An elevator system 1 is applied to a building. The building has multiple floors. In this example, the building is divided into multiple zones. In this example, each zone is located on any floor. At least a portion of the zones in the building is allocated to tenants. Tenants may be, for example, shops or offices that occupy the building for a short period of time, such as a day or an hour. Alternatively, a tenant may be a business that allows users to use a portion of the zone allocated to them for their work, for a short period of time, such as a day or an hour. Alternatively, a tenant may be a non-territorial office (open office) with a free-address system where staff members do not have fixed seats. Examples of tenants include shared office spaces, rental offices, shared offices, and paid study rooms. Multiple zones may be allocated to a single tenant. In this case, some or all of the zones may be located on different floors. In this example, one zone is allocated to each floor of the building.

[0034] A hoistway (not shown) is provided in the building. A hoistway is a vertically long space extending across multiple floors. Landings (not shown) are located on each floor of the building. Landings are places adjacent to the hoistway.

[0035] In this example, a user of the elevator system 1 carries a portable terminal 2. Portable terminal 2 is a mobile information terminal equipped with wireless communication functionality. Portable terminal 2 is, for example, a smartphone. Portable terminal 2 is equipped with a function for presenting information received via wireless communication to the user. Portable terminal 2 presents information to the user, for example, via a screen display. Alternatively, portable terminal 2 may present information to the user via voice, for example. The wireless communication function installed in portable terminal 2 enables direct communication with other devices, for example, via short-range wireless communication, or via a wide-area communication network such as the Internet.

[0036] 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.

[0037] 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 uses the driving force generated by the hoisting machine 6 to travel in the hoistway, thereby transporting users and the like between multiple floors. When the car 7 stops at a certain floor, users enter the car 7 from the landing of that floor or get off the car 7 from the inside to the landing of that floor. The car 7 has a car door 9. The car door 9 is a device that can be opened and closed when the car 7 stops at a certain floor, allowing users to enter the car 7 from the landing of that floor or get off the car 7 from the inside to the landing of that floor. The car 7 has a scale 10. The scale 10 is a device that measures the load weight of the car 7. The car 7 is set to a maximum load weight. The control panel 8 is the part that controls the movement of the car 7 and other operations. The control panel 8 controls the movement of the car 7 including departure, acceleration, deceleration, and parking of the car 7 and opening and closing of the car door 9. The control panel 8 obtains the measured value of the load weight of the car 7 measured by the scale 10.

[0038] The elevator call registration device 4 is a device that accepts elevator call registration operations performed by users. The elevator call registration device 4 accepts, for example, landing call operations. In this case, the elevator call registration device 4 is located at the landing of each floor. A landing call at a particular floor is performed, for example, by a user boarding a car 7 of any elevator 3 from that floor. Furthermore, the elevator call registration device 4 accepts, for example, car call operations. In this case, the elevator call registration device 4 is located inside the car 7 of each elevator 3. A car call in a particular car 7 is performed, for example, so that the user boarding that car 7 can specify their destination floor.

[0039] The group control device 5 is a device that manages the operation of the elevators 3 in the elevator system 1. The group control device 5 is installed in a building and includes a control unit 11, a storage unit 12, an estimation unit 13, a totaling unit 14, a prediction unit 15, and a presentation unit 16.

[0040] The control unit 11 is a part equipped with the function of obtaining and controlling the status of each elevator 3. The status information of the elevator 3 obtained by the control unit 11 includes call information related to the elevator 3 and status information of the car 7 of the elevator 3. The status information of the car 7 includes information such as the 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 information such as the call allocation 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 plan of each elevator 3 through call allocation and other means. The control panel 8 of each elevator 3 controls the operation of the elevator 3, such as the travel of the car 7, according to the operation plan of the control unit 11.

[0041] The storage unit 12 is a component equipped with information storage. It stores tenant identification information, which is used to identify tenants residing in the building, in association with area information for the area assigned to that tenant. Area information for an area includes the area's designated occupancy limit and the floor on which the area is located.

[0042] The estimation unit 13 is a component equipped with a function of estimating the number of passengers aboard the car 7 of each elevator 3. The estimation unit 13 estimates the number of passengers aboard based on the state of the elevator 3 obtained by the control unit 11. For example, the estimation unit 13 estimates the number of passengers aboard the car 7 at a given floor based on information on changes in the measured value of the scale 10 installed on the car 7 when the car 7 stops at that floor.

[0043] The totaling unit 14 is a unit equipped with a function of totaling the number of users using the area allocated to the tenant. The totaling unit 14 totals the number of users based on the number of people getting on and off the cars 7 of each elevator 3 estimated by the estimation unit 13, for example.

[0044] The prediction unit 15 is a component equipped with a function for predicting whether an area allocated to a tenant can be used. The prediction unit 15 predicts whether a user who boards a car 7 of any elevator 3 with the tenant as their destination can use the area. The prediction unit 15 predicts whether the area can be used based on the number of passengers estimated by the estimation unit 13, the number of passengers counted by the count unit 14, and the information stored in the storage unit 12.

[0045] The notification unit 16 is a component equipped with a function to notify users of available floors in the car 7. The notification unit 16 performs notifications based on, for example, the availability predicted by the prediction unit 15. The notification unit 16 performs notifications via, for example, the mobile terminal 2 held by the user. The notification unit 16 transmits information about available floors to the mobile terminal 2 via wireless communication. The notification unit 16 transmits information to the mobile terminal 2 via direct wireless communication. In this case, the notification unit 16 may be, for example, the landing where the user is waiting or a wireless beacon located in the car 7 in which the user is riding. Alternatively, the notification unit 16 may transmit information to the mobile terminal 2 via a wide area communication network such as the Internet. In this case, the mobile terminal 2 identifies the landing where the user is waiting or the car 7 in which the user is riding based on wireless signals emitted by a wireless beacon located in the car 7 in which the user is riding. The mobile terminal 2 may select information to present to the user based on the identified landing or car 7. Alternatively, the presenting unit 16 may present information to the user by, for example, causing a notification device (not shown) to notify the user of the floor information of the available area. In this case, the notification device is disposed, for example, at the landing where the user is waiting or in the car 7 in which the user is boarding. The notification device provides notification through visual information such as a display or auditory information such as voice.

[0046] Figure 2 This is a front view of the call registration device 4 according to the first embodiment.

[0047] exist Figure 2 , an example of a call registration device 4 that is disposed at a hall and receives operations for hall calls is shown.

[0048] The elevator 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 that accepts the operation of the floor call made by the user who wants to move to the upper floor. The down button is a button that accepts the operation of the floor call made by the user who wants to move to the lower floor. The display 18 is a part that presents information to the user at the floor by displaying. The display 18 displays information such as the current position of the car 7 or the direction of travel of the car 7. Here, the elevator 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. In addition, the elevator call registration device 4 may also serve as a notification device.

[0049] Figure 3 This is a diagram showing an example of the hardware configuration of the control panel 8 according to the first embodiment.

[0050] The functions of the control panel 8 can be implemented by a processing circuit. The processing circuit includes at least one processor 8a and at least one memory 8b. The processing circuit includes the processor 8a and the memory 8b and may also include at least one dedicated hardware device, or the processing circuit may include at least one dedicated hardware device instead of the processor 8a and the memory 8b.

[0051] When the processing circuit includes a processor 8a and a memory 8b, the various functions of the control panel 8 are implemented using software, firmware, or a combination of software and firmware. At least one of the software and firmware is described as a program. This program is stored in the memory 8b. The processor 8a implements the various functions of the control panel 8 by reading and executing the program stored in the memory 8b.

[0052] The processor 8a is also known as a CPU (Central Processing Unit), a processing device, an arithmetic device, a microprocessor, a microcomputer, or a DSP. The memory 8b is composed of, for example, nonvolatile or volatile semiconductor memory such as RAM (Random Access Memory), ROM (Read Only Memory), flash memory, EPROM (Erasable Programmable Read Only Memory), or EEPROM (Electrically Erasable Programmable Read Only Memory).

[0053] When the processing circuit has dedicated hardware, the processing circuit is implemented by, for example, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), or a combination thereof.

[0054] Each function of the control panel 8 can be implemented separately by a processing circuit. Alternatively, each function of the control panel 8 can be implemented collectively by the processing circuit. Each function of the control panel 8 can also be implemented partially by dedicated hardware and others by software or firmware. Thus, the processing circuit implements each function of the control panel 8 using dedicated hardware, software, firmware, or a combination thereof.

[0055] Figure 4 This is a diagram showing an example of the hardware configuration of the group management device 5 according to the first embodiment.

[0056] The functions of the group management device 5 can be implemented by a processing circuit. The processing circuit includes at least one processor 5a, at least one memory 5b, and a clock 5c. The processing circuit includes the processor 5a, memory 5b, and clock 5c and may also include at least one dedicated hardware. Alternatively, the processing circuit may include at least one dedicated hardware instead of the processor 5a, memory 5b, and clock 5c.

[0057] When the processing circuit includes a processor 5a and a memory 5b, the various functions of the group management device 5 are implemented using software, firmware, or a combination of software and firmware. At least one of the software and firmware is described as a program. This program is stored in the memory 5b. The processor 5a reads and executes the program stored in the memory 5b to implement the various functions of the group management device 5. When the processing circuit includes a clock 5c, the functions of the group management device 5 that require time information are implemented using a combination of software, firmware, and the clock 5c.

[0058] The processor 5a is also called a CPU, a processing device, an arithmetic device, a microprocessor, a microcomputer, or a DSP. The memory 5b is composed of, for example, a nonvolatile or nonvolatile semiconductor memory such as RAM, ROM, flash memory, EPROM, or EEPROM.

[0059] In the case where the processing circuit has dedicated hardware, the processing circuit is implemented by, for example, a single circuit, a complex circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination thereof.

[0060] Each function of the group management device 5 can be implemented separately by a processing circuit. Alternatively, each function of the group management device 5 can be implemented collectively by the processing circuit. Each function of the group management device 5 can also be implemented partially by dedicated hardware and others by software or firmware. In this way, the processing circuit implements each function of the group management device 5 using dedicated hardware, software, firmware, or a combination thereof.

[0061] Next, use Figures 5 to 9 , an example of presenting information to users in the elevator system 1 will be described.

[0062] Figures 5 to 8 This is a diagram showing an example of data handled in the elevator system 1 according to the first embodiment.

[0063] exist Figure 5shows an example of information stored in storage unit 12. Storage unit 12 stores tenant identification information in association with area information. Storage unit 12 may also store the same tenant identification information in association with multiple areas. In this example, the area information includes information such as the floor containing the area, the maximum number of people allowed in the area, and the hours of use set for the area.

[0064] exist Figure 6 , an example of the number of passengers estimated by the estimation unit 13 is shown. When the call registration device 4 receives a landing call operation at any floor, the estimation unit 13 obtains the landing call information from the control unit 11. At this time, the estimation unit 13 generates a table of the number of passengers. Figure 6 The data shown is an example of a passenger boarding and alighting table. The passenger boarding and alighting table manages information on the number of passengers estimated by the estimation unit 13. The number of passengers boarding and alighting includes the number of passengers boarding and the number of passengers disembarking. The estimation unit 13 estimates the number of passengers boarding and alighting, for example, as follows.

[0065] In this example, a landing call is made at the landing on the first floor. On the first floor, multiple users, including the user who made the landing call, are waiting for the arrival of a car 7. The control unit 11 then assigns the landing call to a desired elevator 3. The control panel 8 of the elevator 3 assigned the landing call causes the car 7 to travel to the first floor.

[0066] In this example, car 7 stops at the 1st floor at 9:00:00 and opens its doors 9. In this example, no users disembark from car 7 at the 1st floor landing. Therefore, the scale 10 does not measure the decrease in load weight associated with the users' disembarkation. A user waiting for car 7 to arrive at the 1st floor landing boards car 7 with its doors 9 open. At this point, the scale 10 measures an increase in load weight as the user boards. In this example, the scale 10 measures an increase of 50% of the maximum load weight of car 7. The change in load weight measured by the scale 10 is recorded in the boarding and alighting table. The user who boards car 7 registers a car call for their destination floor using the call registration device 4 installed inside car 7. In this example, the user whose destination floor is the tenant with tenant identification information "00001" makes a car call to the 5th floor. Furthermore, a user whose destination is the tenant with tenant identification information "00002" makes a car call with the 10th floor 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 its car door 9 and departs from the 1st floor upward.

[0067] The estimation unit 13 estimates the number of people getting on and off the car 7 on the first floor based on the number of people equivalent to the maximum load-bearing weight of the car 7. In this example, the maximum load-bearing weight of the car 7 is equivalent to the weight of 20 users. Since the scale 10 does not measure the decrease in the load-bearing weight after the car door 9 is opened on the first floor, the estimation unit 13 estimates the number of people getting off the car 7 on the first floor to be 0. On the other hand, the scale 10 measures an increase of 50% of the maximum load-bearing weight before the car door 9 is closed on the first floor, so the estimation unit 13 estimates the number of people getting on and off the car 7 on the first floor to be 10. The number of people getting on and off the car 7 on the first floor estimated by the estimation unit 13 is recorded in the number of people getting on and off table.

[0068] Then, after the car 7 stops at the 5th floor at 9:00:30, the car door 9 opens. A user whose destination is the tenant with the tenant identification information "00001" gets off the car 7 with the car door 9 opened to the landing on the 5th floor. At this time, the scale 10 measures the decrease in the load weight as the user gets off. In this example, the scale 10 measures a decrease of 25% of the maximum load weight of the car 7. On the other hand, there are no users who get on the car 7 from the landing on the 5th floor. Therefore, the scale 10 does not measure the increase in the load weight as the users get on. Then, the car 7 closes the car door 9 and departs from the 5th floor upward.

[0069] The estimation unit 13 estimates the number of people boarding and alighting the car 7 on the 5th floor based on the number of people corresponding to the maximum load capacity of the car 7. Since the scale 10 measured a 25% decrease in the maximum load capacity after the car door 9 opened on the 5th floor, the estimation unit 13 estimates the number of people alighting on the 5th floor to be 5. On the other hand, the scale 10 did not measure the increase in the load capacity before the car door 9 closed on the 5th floor, so the estimation unit 13 estimates the number of people boarding and alighting on the 5th floor to be 0.

[0070] Then, at 9:01:00, car 7 stops at the 10th floor and opens its car door 9. A user whose destination is the tenant with tenant identification information "00002" gets off car 7 with its car door 9 open at the 10th floor landing. At this time, as the user gets off, the scale 10 measures a decrease in the load. In this example, the scale 10 measures a decrease of 25% of the maximum load of car 7. Then, a user who was waiting for the arrival of car 7 at the 10th floor landing gets on car 7 with its car door 9 open. At this time, as the user gets on, the scale 10 measures an increase in the load. In this example, the scale 10 measures an increase of 10% of the maximum load of car 7. Then, car 7 closes its car door 9 and departs from the 10th floor.

[0071] The estimation unit 13 estimates the number of people boarding and alighting the car 7 on the 10th floor based on the number of people corresponding to the maximum load capacity of the car 7. Since the scale 10 measured a 25% decrease in the maximum load capacity after the car door 9 opened on the 10th floor, the estimation unit 13 estimates the number of people alighting on the 10th floor to be 5. Furthermore, since the scale 10 measured a 10% increase in the maximum load capacity before the car door 9 closed on the 10th floor, the estimation unit 13 estimates the number of people boarding the car 7 on the 10th floor to be 2.

[0072] exist Figure 7 , there is shown an example of the totaling of the number of users by the totaling unit 14. The totaling unit 14 generates a table of the number of users. Figure 7 The data shown is an example of a user number table. The user number table is a table that manages information on the number of users for each area counted by the counting unit 14. The counting unit 14 counts the number of users, for example, as follows.

[0073] The totaling unit 14, for example, totals the number of users based on the number of people boarding and alighting estimated by the estimating unit 13. For example, when a user has gotten off the car 7 at any floor, the totaling unit 14 deems that the user has used the area included in the floor after getting off and adds the user to the number of users. For example, when a user has boarded the car 7 at any floor, the totaling unit 14 deems that the user has finished using the area included in the floor and subtracts the user from the number of users. The number of users totaled by the totaling unit 14 is recorded in the user number table. For example, when the utilization time of an area ends, the totaling unit 14 resets the information of the area in the user number table.

[0074] exist Figure 8 , there is shown an example of the availability prediction performed by the prediction unit 15. The prediction unit 15 generates an availability table. Figure 8 The data shown is an example of an availability table. The availability table is a table that manages information on availability for each area predicted by the prediction unit 15. The prediction unit 15 predicts availability, for example, as follows.

[0075] The prediction unit 15 calculates the number of people available from that point on for each area by, for example, subtracting the number of people using the area calculated by the calculation unit 14 from the rated number of people for that area stored as area information in the storage unit 12. Based on the number of people boarding and alighting estimated by the estimation unit 13, which has not yet been calculated by the calculation unit 14, the prediction unit 15 predicts that users riding the car 7 will not be able to use the area from that point on if the number of people getting off a certain floor exceeds the number of people available in the area included in that floor. On the other hand, if the number of people getting off a certain floor is less than the number of people available in the area included in that floor, the prediction unit 15 predicts that users riding the car 7 will be able to use the area from that point on.

[0076] The presenting unit 16 presents the prediction result of the predicting unit 15 to the user who will board the car 7 from now on. For example, the presenting unit 16 presents the floor and availability of each area. The presenting unit 16 may also present the number of available people for each available area.

[0077] Next, use Figure 9 An operation example of the elevator system 1 will be described.

[0078] Figure 9 This is a flowchart showing an operation example of the elevator system 1 according to the first embodiment.

[0079] In step S101, the control unit 11 determines whether a landing call has been made at any floor. If the determination result is "No," the elevator system 1 completes the process related to information presentation to the user. If the determination result is "Yes," the control unit 11 assigns the landing call to any car 7. The elevator system 1 then proceeds to step S102.

[0080] In step S102, the estimation 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 landing call is allocated. Then, the process of the elevator system 1 proceeds to step S103.

[0081] In step S103, the control unit 11 determines whether the car 7 to which the landing call is assigned has responded to all registered car calls. If the determination result is "No", the processing of the elevator system 1 proceeds to step S102. If the determination result is "Yes", the processing of the elevator system 1 proceeds to step S104.

[0082] In step S104, the estimation unit 13 estimates the number of passengers boarding and alighting the car 7 to which a landing 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.

[0083] In step S105, the prediction unit 15 calculates the number of available passengers for each area based on the number of passengers totaled by the totaling unit 14 and the area information stored in the storage unit 12. The prediction unit 15 predicts the availability of each area based on the calculated number of available passengers and the number of passengers boarding and alighting the car 7 estimated by the estimation unit 13. The process of the elevator system 1 then proceeds to step S106.

[0084] In step S106, the presenting unit 16 presents the prediction result of the prediction unit 15 on the availability of the car 7 to the user who will board the car 7 from then on. In this case, the presenting unit 16 presents the information to the user who is waiting for the car 7 at the landing, for example. Alternatively, the presenting unit 16 may present the information to the user inside the car 7 when the user boards the car 7 from the landing. The processing of the elevator system 1 related to the information presentation to the user then ends.

[0085] As described above, the elevator system 1 of Embodiment 1 includes a control unit 11, a storage unit 12, an estimation unit 13, a prediction unit 15, and a presentation unit 16. The control unit 11 acquires and controls the status of the elevator 3. The elevator 3 is installed in a building having multiple floors. The storage unit 12 stores tenant identification information for identifying tenants in association with area information. The tenant identification information identifies the tenant to whom at least a portion of an area of ​​the building is allocated. The area information includes the capacity of the area allocated to the tenant and the floor information of the area. The estimation unit 13 estimates the number of passengers boarding and alighting the elevator car 7 of the elevator 3 based on the status of the elevator 3 acquired by the control unit 11. The totaling unit 14 totals the number of users in the areas allocated to the tenants. The prediction unit 15 predicts whether the area allocated to the tenant is available for use based on the number of passengers estimated by the estimation unit 13, the number of users totaled by the totaling unit 14, and the information stored in the storage unit 12. The presentation unit 16 presents the floors of the available areas to users riding in the elevator car 7 based on the availability predicted by the estimation unit 15.

[0086] With this configuration, the floors of the available areas are displayed to the user, making it easier to understand the conditions at the destination. This prevents situations where a user discovers that the area is unavailable after reaching their destination, thereby reducing operational efficiency caused by such users repeatedly using the elevator 3. Furthermore, since users can know the available areas in advance, it is possible to prevent a single user from entering multiple floors as their destination, including areas where availability is unclear. This reduces unnecessary call registrations, thereby minimizing a reduction in the operational efficiency of the elevator system 1. Furthermore, since the available areas can be understood based on the conditions at the destination, user convenience can be further improved.

[0087] Furthermore, the presentation unit 16 presents available floors via the mobile terminal 2 held by the user.

[0088] According to such a configuration, the user can know whether or not the service is available through the portable terminal 2 that the user possesses, thereby further improving the convenience of the user.

[0089] Furthermore, the estimation unit 13 estimates the number of people getting on and off the car 7 based on the measurement value change information of the scale 10 that measures the load weight of the car 7 .

[0090] According to such a configuration, the number of passengers on and off can be estimated based on the measured value of the scale 10 mounted on the car 7 of the elevator 3, so that the elevator system 1 can be configured more easily.

[0091] In addition, when a plurality of areas allocated to different tenants are included in one floor, the totaling unit 14 may estimate which area the users who get off the elevator on that floor will use and total the estimated areas. The totaling unit 14 may also, for example, multiply the number of people who get off the elevator on that floor by the ratio corresponding to the tenant to obtain the number of people using that floor as the total number of people. The ratio corresponding to the tenant is, for example, a ratio corresponding to the area of ​​the area on that floor or the rated number of people. As a more specific example, the totaling unit 14 may, for example, when three people get off the elevator on a floor that includes an area with a rated number of 10 and an area with a rated number of 20, calculate the total number as if one person used the former area and two people used the latter area.

[0092] Furthermore, the estimation unit 13 can also estimate the number of people getting on and off the car 7 based on the number of landing 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 landing calls and car calls, the number of these calls corresponds to the number of people getting on and off the car 7. Therefore, the estimation unit 13 can estimate the number of people getting on and off based on the number of these calls. For example, the estimation unit 13 estimates the number of people getting on the elevator at any floor based on the number of landing calls at the landing of that floor. Furthermore, the estimation unit 13 estimates the number of people getting off the elevator at any floor based on the number of car calls with any floor as the destination, for example.

[0093] Implementation Method 2

[0094] In Embodiment 2, the differences from the example disclosed in Embodiment 1 are described in particular detail. Any features in the example disclosed in Embodiment 1 may be adopted as well as features not described in Embodiment 2.

[0095] In this example, the call registration device 4 receives a destination call operation that specifies the departure floor and destination floor. In this case, the call registration device 4 is, for example, located at the lobby level. A destination call is made by a user boarding a car 7 of any elevator 3 from the lobby level. During a destination call, the user enters their destination floor. This determines that the lobby level, where the call registration device 4 is located, is the departure floor for the destination call, and the floor entered by the user is the destination floor for the destination call. Alternatively, the call registration device 4 may be located at the lobby level of each floor.

[0096] The control unit 11 assigns the destination call received by the call registration device 4 to an arbitrary car 7. The control panel 8 of the elevator 3 assigned the destination call causes the car 7 to travel to the departure floor of the destination call.

[0097] Figure 10 This is a front view of the call registration device 4 according to the second embodiment.

[0098] The call registration device 4 includes a numeric keypad unit 17b and a display 18. The numeric keypad unit 17b includes a plurality of numeric buttons that allow the user to input a destination floor. The display 18 displays information identifying the elevator 3 assigned to the destination call by the control unit 11, for example, to the user who has made a destination call. In this example, the elevator 3 assigned to the landing call, elevator A, is displayed to the user.

[0099] Figure 11 This is a diagram showing an example of data handled in the elevator system 1 according to the second embodiment.

[0100] exist Figure 11 , an example of the number of passengers estimated by the estimation unit 13 is shown. When the call registration device 4 receives a destination call, the estimation unit 13 obtains information about the destination call from the control unit 11. At this time, the estimation unit 13 generates a table of the number of passengers based on the destination call. Figure 11 The data shown is an example of a table of the number of passengers boarding and alighting based on a destination call. The estimation unit 13 estimates the number of passengers boarding and alighting, for example, as follows.

[0101] In this example, five users each made a destination call to the 5th floor as their destination floor at the call registration device 4 located at the 1st floor landing until 9:00:00. Furthermore, five users each made a destination call to the 10th floor as their destination floor at the call registration device 4 located at the 1st floor landing until 9:00:00. Furthermore, one user made a destination call to the 1st floor as their destination floor at the call registration device 4 located at the 10th floor landing until 9:01:00. The control unit 11 assigns these destination calls to the elevator 3 of elevator No. A. The control panel 8 of elevator No. A causes the car 7 to travel to the 1st floor.

[0102] The estimation unit 13 estimates the number of people getting on and off the car 7 of the elevator No. A on each floor based on the number of destination calls of the elevator 3 assigned to the elevator No. A. The estimation unit 13 estimates the number of people getting on and off as if each user has performed a destination call operation. When each user performs a destination call operation, the number of destination calls corresponds to the number of people getting on and off the car 7. The estimation unit 13 estimates the number of people getting on the elevator at the 1st floor to be 10 based on the number of destination calls with the 1st floor assigned to the elevator No. A as the departure floor. In addition, the estimation unit 13 estimates the number of people getting off the elevator at the 5th floor to be 5 based on the number of destination calls with the 5th floor assigned to the elevator No. A. In addition, the estimation unit 13 estimates the number of people getting off the elevator at the 10th floor to be 5 based on the number of destination calls with the 10th floor assigned to the elevator No. A. The number of people getting on and off at each floor estimated by the estimation unit 13 is recorded in the number of people getting on and off table.

[0103] The totaling unit 14, for example, totals the number of users based on the number of people boarding and alighting estimated by the estimating unit 13. For example, if a user disembarks from the elevator car 7 on any floor, the totaling unit 14 deems that the user will use the area included in that floor after disembarking and adds the user to the number of users. For example, if a user is about to board the elevator car 7 on any floor, the totaling unit 14 deems that the user has finished using the area included in that floor and subtracts the user from the number of users. The number of users totaled by the totaling unit 14 is recorded in the user number table. For example, when the usage time of an area ends, the totaling unit 14 resets the information for that area in the user number table.

[0104] The prediction unit 15 calculates the number of people available from that point on for each area by, for example, subtracting the number of people using the area calculated by the calculation unit 14 from the rated number of people for that area stored as area information in the storage unit 12. Based on the number of people boarding and alighting estimated by the estimation unit 13, which has not yet been calculated by the calculation unit 14, the prediction unit 15 predicts that users who intend to use the car 7 from that point on will not be able to use the area if the number of people getting off a certain floor exceeds the number of people available in the area included in that floor. On the other hand, if the number of people getting off a certain floor is less than the number of people available in the area included in that floor, the prediction unit 15 predicts that users who intend to use the car 7 from that point on will be able to use the area.

[0105] The notification unit 16 notifies users who are about to board the car 7 of the predicted availability result produced by the prediction unit 15. For example, the notification unit 16 notifies each area of ​​the floor and availability of the area. The notification unit 16 may also indicate the number of available passengers for each available area. The notification unit 16 may also use the display 18 of the call registration device 4 as a notification device to notify users of the predicted availability result. The notification unit 16 may also prompt users who have entered an unavailable destination floor to re-enter their destination floor.

[0106] As described above, the estimation unit 13 of the elevator system 1 according to the second embodiment estimates the number of people getting on and off the car 7 based on the number of destination calls assigned to the car 7 by the control unit 11. A destination call is a call that specifies a departure floor and a destination floor.

[0107] Generally, destination calls are often made by individual users. Therefore, the number of passengers getting on and off can be estimated with greater accuracy based on the number of users and the corresponding number of destination calls.

[0108] Alternatively, the estimation unit 13 may combine the estimation of the number of passengers alighting and boarding based on the change in the measured value of the scale 10 with the estimation of the number of passengers alighting and boarding based on the number of destination calls. For example, the estimation unit 13 may estimate the number of passengers alighting and boarding at a floor where a call registration device 4 for accepting destination calls is located based on the number of destination calls, and may also estimate the number of passengers alighting and boarding at a floor where a call registration device 4 for accepting landing calls from undetermined destination floors is located based on the change in the measured value of the scale 10.

[0109] Alternatively, a destination call may be made, for example, using a user's portable terminal 2. When registering a destination call, the user enters both the departure floor and the destination floor into the portable terminal 2. The departure floor and the destination floor may also be pre-set in the portable terminal 2 by the user, for example. The portable terminal 2 transmits the destination call information to the control unit 11 via a wide area communication network such as the Internet.

[0110] Implementation 3

[0111] In Embodiment 3, differences from the example disclosed in Embodiment 1 or 2 are described in particular detail. Any features not described in Embodiment 3 may be adopted from the examples disclosed in Embodiment 1 or 2.

[0112] Figure 12 It is a configuration diagram of an elevator system 1 according to a third embodiment.

[0113] 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 for managing entry and exit of at least any area in the building. The entry and exit management device 19 manages users entering and exiting areas in the building by using user identification information for identifying the users. Here, the user identification information is, for example, information such as a number uniquely assigned to the user. In this case, the user identification information is stored in, for example, an identification body such as an IC card held by the user. Alternatively, the user identification information may be biometric information such as the user's fingerprint information, vein information, or iris information. The entry and exit management device 19 includes a reading device 20 for reading the user identification information of each user. The reading device 20 reads the user identification information from the identification body held by the user, for example, by short-range wireless communication. Alternatively, the reading device 20 may also read, for example, the user's biometric information as the user identification information.

[0114] In this example, the call registration device 4 cooperates with the reader 20 of the entry and exit management device 19. Alternatively, the call registration device 4 and the reader 20 may be integrated. After the reader 20 reads the user identification information, the call registration device 4 accepts a call registration operation from the user identified by the user identification information. For example, the call registration device 4 accepts a destination call registration operation.

[0115] Next, use Figure 13 and Figure 14 , an example of information presentation to users in the elevator system 1 will be described.

[0116] Figure 13 and Figure 14 This is a diagram showing an example of data processed in the elevator system 1 according to the third embodiment.

[0117] exist Figure 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 area information stored in the storage unit 12 in association with the tenant identification information includes information such as the floor containing the area, the maximum number of people set for the area, whether security settings are set for the area, user identification information identifying users who can use the area, and the hours of use set for the area.

[0118] exist Figure 14 , shows an example of the number of passengers estimated by the estimation unit 13. When the call registration device 4 receives a destination call, the estimation unit 13 obtains the destination call information from the control unit 11. At this time, the estimation unit 13 generates a table of the number of passengers based on the destination call. Figure 14The data shown is an example of a table of the number of passengers boarding and alighting based on a destination call. The estimation unit 13 estimates the number of passengers boarding and alighting, for example, as follows.

[0119] In this example, the reader 20 located at the landing on the 1st floor reads the user's user identification information "00001" until 9:00:00. At this point, the call registration device 4 accepts a destination call from the user with the 5th floor as the destination floor. The control unit 11 determines whether the user's available area is on the 5th floor, which is the destination floor. For example, the control unit 11 determines that all users can use the area with a security setting of "no." For example, the control unit 11 determines that users who have pre-registered user identification information can use the area with a security setting of "yes," and that users who have not registered user identification information cannot use the area. If the control unit 11 determines that the available area for the user with user identification information "00001" is on the 5th floor, the control unit 11 assigns the user's destination call to the car 7 of any elevator 3. On the other hand, if the control unit 11 determines that the user's available area is not on the 5th floor, the control unit 11 does not assign the user's destination call to the car 7 of the elevator 3.

[0120] Furthermore, the reader 20 located at the landing station on the 1st floor reads the user's user identification information "00030" until 9:00:00. At this time, the call registration device 4 accepts the destination call operation made by the user with the 10th floor as the destination floor. The control unit 11 determines whether the available area of ​​the user is on the 10th floor, which is the destination floor. If the control unit 11 determines that the available area of ​​the user with the user identification information "00030" is on the 10th floor, the control unit 11 assigns the user's destination call to the car 7 of any elevator 3. On the other hand, if the control unit 11 determines that the user's available area is not on the 10th floor, the control unit 11 does not assign the user's destination call to the car 7 of the elevator 3.

[0121] Furthermore, the reader 20 located at the landing on the 10th floor reads the user's user identification information "00025" until 9:01:00. At this point, the call registration device 4 accepts the user's destination call operation with the 1st floor as the destination floor. The control unit 11 determines whether the user's available area is within the 1st floor, which is the destination floor. For example, if the destination floor is the lobby floor, the control unit 11 determines that all users can use that floor.

[0122] The estimation unit 13 estimates the number of passengers boarding and alighting the elevator car 7 of the elevator 3 at each floor based on the number of destination calls assigned to the elevator 3. Since each user performs a destination call, the estimation unit 13 estimates the number of passengers boarding and alighting by assuming that the number of destination calls corresponds to the number of passengers boarding and alighting the elevator car 7. The number of passengers boarding and alighting estimated by the estimation unit 13 at each floor is recorded in a passenger boarding and alighting table.

[0123] The totaling unit 14, for example, totals the number of users based on the number of people getting on and off estimated by the estimation unit 13. For example, when a user gets off the car 7 on any floor, the totaling unit 14 deems that the user will use the area included in the floor after getting off and adds the user to the number of users. In this case, if the area where the user identification information of the user is registered is located on the floor, the totaling unit 14 may also deem that the user will use the area and add the user to the number of users. For example, when a user gets on the car 7 on any floor, the totaling unit 14 deems that the user has finished using the area included in the floor and subtracts the user from the number of users. In this case, if the area where the user identification information of the user is registered is located on the floor, the totaling unit 14 may also deem that the user has finished using the area and add the number of users. The number of users totaled by the totaling unit 14 is recorded in the number of users table. For example, when the usage time of the area ends, the totaling unit 14 resets the information of the area in the number of users table.

[0124] For example, the prediction unit 15 calculates the number of people available for each area from that point forward by subtracting the number of users counted by the counting unit 14 from the rated number of people for that area stored as area information in the storage unit 12. For users whose number of users has not yet been counted by the counting unit 14, if the available number of people in the area they wish to use is 0, the prediction unit 15 predicts that the user will not be able to use that area. On the other hand, for users whose number of users has not yet been counted by the counting unit 14, if the available number of people in the area they wish to use is greater than 0, the prediction unit 15 predicts that the user will be able to use that area.

[0125] The notification unit 16 presents the predicted availability result of the prediction unit 15 to the user who has made a destination call. For example, the notification unit 16 may present, for each zone, the floor and availability of that zone. The notification unit 16 may also present the number of available passengers for each available zone. The notification unit 16 may also use the display 18 of the call registration device 4 as a notification device to present the predicted availability result to the user. The notification unit 16 may also prompt a user who has entered an unavailable destination floor to re-enter their destination floor.

[0126] Next, use Figure 15 An operation example of the elevator system 1 will be described.

[0127] Figure 15 This is a flowchart showing an operation example of the elevator system 1 according to the third embodiment.

[0128] In step S201, the control unit 11 determines whether a user, whose user identification information has been read by the reader 20 of the entry and exit management device 19, has made a destination call. If the determination result is "No," the processing 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. Based on the user identification information and the area information stored in the storage unit 12, the control unit 11 determines whether to restrict the allocation of the destination call of the identified user. If the control unit 11 determines that the allocation of the destination call is not restricted, it allocates the destination call to any car 7. The processing of the elevator system 1 then proceeds to step S202.

[0129] In step S202, the estimation unit 13 acquires information on the destination call of the car 7 assigned to the elevator 3. Then, the process of the elevator system 1 proceeds to step S203.

[0130] In step S203, the estimation unit 13 estimates the number of people boarding and alighting the car 7 of the elevator 3 based on the departure floor and destination floor of each user's destination call. Then, the process of the elevator system 1 proceeds to step S204.

[0131] In step S204, the prediction unit 15 calculates the number of available passengers for each area based on the number of passengers totaled by the totaling unit 14 and the area information stored in the storage unit 12. The prediction unit 15 predicts the availability of each area based on the calculated number of available passengers and the number of passengers boarding and alighting the car 7 estimated by the estimation unit 13. The process of the elevator system 1 then proceeds to step S205.

[0132] In step S205, the presenting unit 16 presents the prediction result of the prediction unit 15 regarding availability to the user who will then board the car 7. In this case, the presenting unit 16 presents the information to the user who has made a destination call, for example. The processing of the elevator system 1 related to the presentation of information to the user then ends.

[0133] As described above, the elevator system 1 of the third embodiment acquires user identification information for identifying users entering and exiting areas allocated to tenants from the entry and exit management device 19. The entry and exit management device 19 manages the entry and exit of users into and out of areas allocated to tenants.

[0134] The totaling unit 14 also totals the number of users using the area using the number of people entering and leaving the area based on information obtained from the entry and exit management device 19. The number of people entering and leaving the area is estimated by the estimating unit 13 as, for example, the number of people getting on and off the cars 7 at the floors including the area.

[0135] According to such a configuration, the number of users of an area is counted in correspondence with the user, thereby making it possible to count the number of users with higher accuracy.

[0136] The storage unit 12 also stores the tenant identification information of a tenant in association with the user identification information identifying a user who can use the tenant. The control unit 11 identifies the user who has registered a call and intends to board the car 7 based on the user identification information obtained from the entry and exit management device 19. If the user identification information of the user who registered the call does not identify a user who can use the tenant, the control unit 11 restricts the allocation of the call to the car 7.

[0137] According to such a configuration, even if a user inputs a floor where no available area exists as a call destination floor, the call will not be registered, thereby further improving the safety of the building.

[0138] The prediction unit 15 also identifies users who have registered their calls and are about to board the car 7 based on user identification information acquired from the entry and exit management device 19. The prediction unit 15 predicts whether the area allocated to the tenant is available for each user based on the user identification information.

[0139] By making such a determination for each user, it is possible to make a more accurate determination of whether or not the data can be used.

[0140] Furthermore, the control unit 11 may restrict allocation of calls to the cars 7 for floors that do not include the area predicted as available by the prediction unit 15. For example, even if a call is made by a user whose user identification information is registered for a certain area and the floor includes the area as the destination floor, the control unit 11 will not allocate the call if the prediction unit 15 predicts that the area is unavailable for the user based on the number of users, etc.

[0141] According to this structure, even if a user can use the destination area for safety reasons, his movement is restricted according to the conditions of the destination. Therefore, the user will use other available areas. This makes it possible to evenly use each area in the building.

[0142] Furthermore, the presenting unit 16 may present a floor of a recommended area among the available areas to a user who has registered for an elevator call and intends to board the car 7, based on the number of passengers estimated by the estimating unit 13, the number of users totaled by the totaling unit 14, and the information stored in the storage unit 12. For example, when multiple areas on different floors are allocated to a single tenant, the presenting unit 16 may present the area with the largest margin of available passengers as a recommended area to the user intending to use the tenant.

[0143] According to such a configuration, the user can designate a destination floor more smoothly by referring to the recommendation of the presentation unit 16 .

[0144] Furthermore, the control unit 11 may automatically register a call with a floor in the area recommended by the presentation unit 16 as the destination floor. For example, the control unit 11 may register a destination call with a floor in the area recommended by the presentation unit 16 as the destination floor without waiting for the user to input the destination floor. The control unit 11 assigns the registered destination call to a car 7 of any elevator 3.

[0145] According to this structure, users do not need to spend time selecting the destination floor and can evenly use each area in the building. As a result, users can avoid unnecessary congestion and the like, and convenience is further improved.

[0146] Implementation 4

[0147] In Embodiment 4, differences from the examples disclosed in Embodiments 1 to 3 are described in particular detail. Any features not described in Embodiment 4 may be adopted from the examples disclosed in Embodiments 1 to 3.

[0148] Figure 16 This is a configuration diagram of an elevator system 1 according to a fourth embodiment.

[0149] A monitoring device 21 is installed in a building employing the elevator system 1. Monitoring device 21 monitors the building's conditions. In this example, monitoring device 21 includes a camera 22 that captures images of the building's interior. Camera 22 is located, for example, at a location such as a landing where it can capture images of elevator 3. Monitoring device 21 determines the number of users boarding and alighting elevator car 7 based on the images captured by camera 22. Monitoring device 21 outputs the number of users determined based on the images as correction information to the estimation unit 13 of the group control device 5.

[0150] In this example, the area information stored in the storage unit 12 in association with the tenant identification information is updated based on information input from outside the group management device 5. Examples of information input from outside the group management device 5 include changes in parameter settings for the elevator 3. Alternatively, information input from outside the group management device 5 may include signals input via the monitoring device 21. This information is input from outside the group management device 5, for example, by a building manager or the like via a terminal device connected to a wide area communication network such as the Internet.

[0151] Next, use Figure 17 An operation example of the elevator system 1 will be described.

[0152] Figure 17 This is a flowchart showing an operation example of the elevator system 1 according to the fourth embodiment.

[0153] The elevator system 1 of the fourth embodiment operates in steps S301 to S304 in the same manner as steps S101 to S104 of the elevator system 1 of the first embodiment. After the estimation unit 13 estimates the number of passengers alighting or boarding, the process of the elevator system 1 of the fourth embodiment proceeds to step S305. Alternatively, the elevator system 1 of the fourth embodiment may operate in the same manner as steps S201 to S203 of the elevator system 1 of the third embodiment, instead of steps S301 to S304. Alternatively, the elevator system 1 of the fourth embodiment may operate in the same manner as steps S201 to S203 of the elevator system 1 of the third embodiment, in parallel with steps S301 to S304. After the estimation unit 13 estimates the number of passengers alighting or boarding, the process of the elevator system 1 of the fourth embodiment proceeds to step S305.

[0154] In step S305, the estimation unit 13 determines whether the 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.

[0155] In step S306, the estimation unit 13 corrects the estimated number of passengers based on the correction information. For example, the estimation unit 13 may make errors in the number of passengers estimated due to differences in weight among users or the weight of luggage carried by users. Alternatively, errors may occur in the estimation unit 13's number of passengers if a user, for example, does not make a destination call and instead rides with another user traveling to the same destination. In such cases, the estimation unit 13 corrects the number of passengers based on the number of passengers included in the correction information. The elevator system 1 then proceeds to step S307.

[0156] In steps S307 and S308, the elevator system 1 of embodiment 4 operates in the same manner as steps S105 and S106 of the elevator system 1 of embodiment 1. Alternatively, the elevator system 1 of embodiment 4 may operate in the same manner as steps S204 and S205 of the elevator system 1 of embodiment 3, instead of steps S307 and S308.

[0157] As described above, the storage unit 12 of the elevator system 1 according to the fourth embodiment updates the area information stored in association with the tenant identification information based on information input from the outside. The information input from the outside is at least one of a signal input from the monitoring device 21 that monitors the condition of the building or a change in the parameter setting of the elevator 3.

[0158] This configuration makes it possible to easily change the area allocation to tenants. For example, when the area allocation to a tenant is for a short period of time, such as a day or an hour, it is possible to more easily perform updates such as changing or canceling the allocation.
