[Figure 6] FIG. 10 is a block diagram of an elevator system according to a second embodiment. DETAILED DESCRIPTION OF THE INVENTION

[0010] The embodiments of the present disclosure will be described with reference to the accompanying drawings. In each drawing, the same or corresponding parts are designated by the same reference numerals. Duplicate descriptions of these parts will be appropriately simplified or omitted.

[0011] Embodiment 1 FIG. 1 is a configuration diagram of a building to which the elevator system according to the first embodiment is applied.

[0012] The elevator system 1 in FIG. 1 is installed in a building 2. A hoistway 3 passes through each floor of the building 2. A machine room 4 is installed directly above the hoistway 3. A plurality of landings 5 ​​are installed on each floor of the building 2. Each of the plurality of landings 5 ​​faces the hoistway 3.

[0013] The hoisting machine 6 is provided in the machine room 4. The main rope 7 is wound around the hoisting machine 6. The car 8 is suspended on one side of the main rope 7 inside the hoistway 3. The counterweight 9 is suspended on the other side of the main rope 7 inside the hoistway 3.

[0014] The car notification device 10 includes a car display 11 and a car speaker 12. For example, the car display 11 is a liquid crystal display. The car display 11 is provided inside the car 8. The car display 11 can notify users inside the car 8 of the information by displaying the information on a screen. The car speaker 12 is provided inside the car 8. The car speaker 12 can notify users inside the car 8 of the information by emitting the information as sound.

[0015] The weighing device 13 is provided at the bottom of the basket 8. The weighing device 13 can measure the weight inside the basket 8.

[0016] The plurality of hall doors 14 are provided at the entrances and exits of the plurality of halls 5, respectively. The plurality of hall operating panels 15 are provided at the plurality of halls 5, respectively.

[0017] The plurality of hall notification devices 16 are provided at the plurality of halls 5, respectively. Each of the plurality of hall notification devices 16 includes a hall display 17 and a hall speaker 18. For example, the hall display 17 is a liquid crystal display. For example, the hall display 17 is provided next to the hall door 14. The hall display 17 can notify users present at the hall 5 of the information by displaying the information on a screen. The hall speaker 18 is provided at the hall 5. The hall speaker 18 can notify users present at the hall 5 of the information by emitting the information as sound.

[0018] The control panel 19 is provided in the machine room 4. The control panel 19 can control the entire elevator system 1. The notification control device 20 is provided in the machine room 4. The notification control device 20 is electrically connected to the car notification device 10, the plurality of hall notification devices 16, and the control panel 19.

[0019] The elevator system 1 includes a call server device 21. For example, the call server device 21 is provided in a building separate from the building 2. The call server device 21 can communicate with the control panel 19 via a communication network.

[0020] The mobile terminal 22 is carried by a user of the elevator system 1. For example, the mobile terminal 22 is a smartphone capable of activating a dedicated application. The mobile terminal 22 can communicate with the call server device 21 via a communication network.

[0021] When the elevator system 1 is operating normally, the control panel 19 drives the hoist 6 to rotate. The main rope 7 moves following the rotation of the hoist 6. The car 8 and the counterweight 9 move up and down in opposite directions following the movement of the main rope 7. The car 8 then arrives at the destination floor.

[0022] During certain peak hours, such as in the morning or evening, the number of people using the elevator system 1 temporarily increases. In this case, it is expected that the car 8 will become congested, for example, as passengers attempt to board the car 8 when it is nearly full. For example, during certain peak hours, the notification control device 20 causes each of the hall notification devices 16 to notify all passengers of information urging them to make a call, including the destination floor. A user makes a call by operating the portable terminal 22 carried by the user. Specifically, the user operates the portable terminal 22 to launch a dedicated application. The portable terminal 22 accepts input of the destination floor of the car 8 from the user based on the dedicated application. The portable terminal 22 identifies the floor on which the user is currently located as the departure floor based on radio waves from a beacon device (not shown) installed at the hall 5. The portable terminal 22 transmits call information, including the departure floor and the input destination floor, to the call server device 21 via a communication network.

[0023] When the call server device 21 receives the call information, it identifies the building 2 corresponding to the call information. The call server device 21 transmits the call information to a control panel 19 installed in the identified building 2. The control panel 19 operates the car 8 based on the call information from the call server device 21.

[0024] The hall operating panel 15 may also receive input of a destination floor from a user. When a destination floor is input, the hall operating panel 15 transmits call information including the departure floor, which is the floor on which the hall operating panel 15 is installed, and the destination floor to the control panel 19. The control panel 19 operates the car 8 based on the call information from the hall operating panel 15.

[0025] The notification control device 20 stores the number of passengers scheduled to disembark from the car 8 at each floor. When the control panel 19 receives call information, the notification control device 20 acquires the call information from the control panel 19. The notification control device 20 calculates the number of passengers scheduled to disembark from the car 8 at each floor based on the call information. Specifically, when the destination floor included in the call information is the third floor, the notification control device 20 increases the number of passengers scheduled to disembark at the third floor by one. When the car 8 departs from the third floor, the notification control device 20 resets the number of passengers scheduled to disembark at the third floor to zero.

[0026] When the car 8 is in operation, the notification control device 20 causes the car notification device 10 to notify the number of passengers expected to disembark at the next floor where the car 8 will stop. Specifically, the car display 11 displays the next floor and the number of passengers expected to disembark at that floor on a screen based on a command from the notification control device 20. At this time, the car speaker 12 may emit a sound indicating the number of passengers expected to disembark at the next floor. When the car 8 stops at the first floor where one of the multiple halls 5 is installed, the notification control device 20 causes the car notification device 10 to notify the number of passengers expected to disembark at the first floor and a message urging passengers to cooperate in disembarking. Specifically, the car display 11 flashes characters indicating the number of passengers expected to disembark. The car display 11 displays characters urging passengers to cooperate in disembarking. The car speaker 12 emits a sound indicating the number of passengers expected to disembark and a sound urging passengers to cooperate in disembarking.

[0027] The weighing device 13 transmits information indicating the weight inside the car 8 to the control panel 19. The notification control device 20 acquires the information indicating the weight inside the car 8 measured by the weighing device 13 via the control panel 19. When passengers disembark from the car 8, the notification control device 20 calculates the estimated number of passengers who actually disembarked from the car 8 at that floor based on the change in the weight inside the car 8. The notification control device 20 notifies the car notification device 10 of the estimated number of passengers. If the estimated number of passengers who actually disembarked is equal to or greater than the planned number of passengers, the notification control device 20 notifies the car notification device 10 and the hall notification device 16 at that floor that disembarkation has been completed.

[0028] Next, an example of a screen displayed by the car display 11 will be described with reference to FIG. FIG. 2 is a diagram showing a screen displayed by a car display of the elevator system according to the first embodiment.

[0029] 2, for example, the car display 11 displays characters indicating that the next floor is floor 3. The car display 11 also displays characters indicating that the number of passengers expected to get off at floor 3 is four.

[0030] Next, the elevator system 1 will be described with reference to FIG. Figure 3 is a block diagram of the elevator system according to the first embodiment. Note that the car 8 is not shown in Figure 3. Also shown in Figure 3 are one of the multiple hall operating panels 15, one of the multiple hall displays 17, and one of the multiple hall speakers 18.

[0031] As shown in FIG. 3, the notification control device 20 includes a call information acquisition unit 23, a planned number of passengers calculation unit 24, an estimated number of passengers calculation unit 25, a car notification unit 26, and a hall notification unit 27.

[0032] When the control panel 19 receives the call information, the call information acquisition unit 23 acquires the call information from the control panel 19. Note that the control panel 19 may be set to transmit the call information to the call information acquisition unit 23 when it receives the call information.

[0033] The expected number of passengers calculation unit 24 stores information on the expected number of passengers who will disembark from the car 8 on each floor of the building 2 (not shown in Fig. 3). When the call information acquisition unit 23 acquires call information, the expected number of passengers calculation unit 24 identifies the destination floor included in the call information. The expected number of passengers calculation unit 24 adds 1 to the expected number of passengers on the identified destination floor.

[0034] The planned number of passengers calculation unit 24 detects that a car 8 has departed from a certain floor based on information from the control panel 19. In this case, the planned number of passengers calculation unit 24 resets the planned number of passengers at that floor to 0.

[0035] The estimated number of passengers calculation unit 25 acquires information about the weight inside the car 8 measured by the scale device 13 via the control panel 19. The estimated number of passengers calculation unit 25 calculates the estimated number of passengers who actually disembarked from the car 8 based on the change in the weight inside the car 8. For example, the estimated number of passengers calculation unit 25 calculates the estimated number of passengers who disembarked from the car 8 at the first floor, which is the stopping floor, by dividing the amount of decrease in the weight inside the car 8 by a preset human weight.

[0036] The car notification unit 26 acquires information related to the operation of the car 8 from the control panel 19. The car notification unit 26 identifies the next stopping floor for the car 8. The car notification unit 26 creates a first command to notify the second floor, which is the next stopping floor, and the expected number of passengers at the next stopping floor. The car notification unit 26 causes the car notification device 10 to notify the information based on the first command. When the expected number of passengers calculation unit 24 adds the expected number of passengers, the car notification unit 26 recreates the first command and causes the car notification device 10 to notify the information.

[0037] When the car 8 stops at a certain floor, the car notification unit 26 generates a second command to notify the planned number of passengers getting off and to encourage passengers to cooperate in getting off. The car notification unit 26 causes the car notification unit 26 to notify the information based on the second command.

[0038] When the car 8 is parked at a certain floor, the car notification unit 26 determines whether the estimated number of passengers who disembarked at that floor is equal to or greater than the planned number of passengers corresponding to that floor. If the car notification unit 26 determines that the estimated number of passengers is equal to or greater than the planned number of passengers, it generates a third command to notify that disembarkation is complete. Based on the third command, the car notification unit 26 causes the car notification device 10 to notify the information. Note that the car notification unit 26 may also generate a third command and cause the car notification device 10 to notify the information when the estimated number of passengers who actually disembarked is equal to or greater than the planned number plus a specified number.

[0039] When the car notification unit 26 creates the third command, the hall notification unit 27 creates a fourth command that notifies the same content as the third command. Based on the fourth command, the hall notification unit 27 notifies the hall notification device 16 of the floor where the car 8 is stopped of information.

[0040] The hall notification unit 27 creates a fifth command to notify all users of information urging them to make a call including the destination floor during a predetermined specific time period. The hall notification unit 27 causes each of the plurality of hall notification devices 16 to notify information based on the fifth command. Specifically, the hall notification unit 27 causes the hall notification device 16 to notify the users of the urging them to make a call from the mobile terminal 22. Note that the hall notification unit 27 may also cause the hall notification device 16 to notify the users of the urging them to make a call specifying the destination floor from the hall operating panel 15 even if the call has already been registered.

[0041] Next, an outline of the operation of the notification control device 20 will be described with reference to FIG. FIG. 4 is a flowchart for explaining an outline of the operation of the notification control device of the elevator system in the first embodiment.

[0042] The notification control device 20 repeats the operations shown in the flowchart of Fig. 4. During this time, the notification control device 20 continues to update the value of the expected number of passengers. In step S01, the notification control device 20 causes the car notification device 10 to notify the next stopping floor and the expected number of passengers at the next stopping floor.

[0043] Thereafter, the operation of step S02 is performed. In step S02, the notification control device 20 determines whether or not the car 8 has arrived at the next floor.

[0044] If it is determined in step S02 that the train has not arrived at the next floor, the notification control device 20 repeats the operations from step S01 onwards.

[0045] If it is determined in step S02 that the vehicle has arrived at the next floor, the notification control device 20 performs the operation of step S03. In step S03, the notification control device 20 causes the car notification device 10 to notify the expected number of passengers getting off and a message encouraging passengers to cooperate in getting off. At this time, the notification control device 20 may also cause the hall notification device 16 to notify the expected number of passengers getting off and a message encouraging passengers to cooperate in getting off.

[0046] Thereafter, the operation of step S04 is performed. In step S04, the notification control device 20 determines whether or not the estimated number of passengers who have disembarked at the floor is equal to or greater than the planned number of passengers corresponding to the floor.

[0047] If it is determined in step S04 that the estimated number of people is not equal to or greater than the planned number of people, the notification control device 20 repeats the operation of step S04.

[0048] If it is determined in step S04 that the estimated number of passengers is equal to or greater than the planned number of passengers, the notification control device 20 performs the operation of step S05. In step S05, the notification control device 20 causes the car notification device 10 and the hall notification device 16 to notify that disembarkation has been completed.

[0049] Thereafter, the operation of step 06 is performed. In step S06, the notification control device 20 determines whether or not the car 8 has departed.

[0050] If it is determined in step S06 that the car 8 has not departed, the notification control device 20 repeats the operation of step S06.

[0051] If it is determined in step S06 that the car 8 has departed, the notification control device 20 performs the operation of step S07. In step S07, the notification control device 20 resets the expected number of passengers for the floor from which the car has departed to zero.

[0052] Thereafter, the notification control device 20 repeats the operations from step S01 onwards.

[0053] In addition, even if the notification control device 20 determines in step S04 that the estimated number of passengers is not equal to or greater than the planned number of passengers, if it determines that the car 8 has departed, it may perform the operation of step S07. After that, the notification control device 20 may perform the operations from step S01 onwards.

[0054] According to the first embodiment described above, the notification control device 20 includes an expected passenger number calculation unit 24 and a car notification unit 26. The car notification unit 26 notifies the car notification device 10 of the expected number of passengers disembarking from the car 8 on the first floor. This allows passengers inside the car 8 to cooperate with the disembarking passengers. At this time, the passengers inside the car 8 can cooperate according to the expected number of passengers disembarking. Specifically, when the expected number of passengers is relatively large, passengers near the entrance / exit of the car 8 can temporarily exit the car 8, for example. This allows passengers to easily disembark from the car 8.

[0055] Furthermore, when the car 8 is moving to the second floor where it will next stop, the notification control device 20 causes the car notification device 10 to notify the number of passengers expected to disembark at the second floor. Therefore, the notification control device 20 can allow the passengers inside the car 8 to make a decision in advance about whether to cooperate with the disembarking operation.

[0056] The notification control device 20 further includes an estimated number of passengers calculation unit 25. When the estimated number of passengers disembarking from the car 8 is equal to or greater than the planned number of passengers, the notification control device 20 issues a notification to that effect. This allows the notification control device 20 to notify users of the timing to end their cooperation with disembarking. For example, a user who has left the car 8 to help with disembarking can quickly return to the inside of the car 8. As a result, the operating efficiency of the elevator system 1 can be improved.

[0057] The notification control device 20 also includes a hall notification unit 27. The notification control device 20 causes the hall notification device 16 to notify the user that they should make a call including the destination floor. For example, a call including the destination floor is a call made from the mobile terminal 22. Therefore, the notification control device 20 can make the expected number of passengers closer to the number of passengers who actually get off the vehicle.

[0058] The elevator system 1 also includes a control panel 19, a car alarm device 10, a weighing device 13, and an alarm control device 20. This allows passengers inside the car 8 to cooperate with passengers getting off. As a result, passengers can easily get off the car 8.

[0059] The elevator system 1 may include a plurality of cars 8 and a plurality of control panels 19. In this case, the elevator system 1 may include a group control device that allocates calls to the plurality of control panels 19.

[0060] The car notification device 10 only needs to include at least one of the car display 11 and the car speaker 12. The car display 11 may be a projector that projects information onto the car door.

[0061] The hall notification device 16 may include at least one of a hall display 17 and a hall speaker 18. The hall display 17 may be a projector that projects information onto the wall of the hall 5 or the hall door 14.

[0062] For example, during rush hours in the morning, the operation of the notification control device 20 may be performed together with other special control operations that the control panel 19 performs during rush hours.

[0063] Next, an example of hardware constituting the notification control device 20 will be described with reference to FIG. FIG. 5 is a hardware configuration diagram of the notification control device of the elevator system according to the first embodiment.

[0064] Each function of the notification control device 20 may be realized by a processing circuit. For example, the processing circuit includes at least one processor 100a and at least one memory 100b. For example, the processing circuit includes at least one dedicated hardware 200.

[0065] When the processing circuit includes at least one processor 100a and at least one memory 100b, each function of the notification control device 20 is realized by software, firmware, or a combination of software and firmware. At least one of the software and firmware is written as a program. At least one of the software and firmware is stored in the at least one memory 100b. The at least one processor 100a realizes each function of the notification control device 20 by reading and executing the program stored in the at least one memory 100b. The at least one processor 100a is also referred to as a central processing unit, processing device, arithmetic unit, microprocessor, microcomputer, or DSP. For example, the at least one memory 100b may be a non-volatile or volatile semiconductor memory such as RAM, ROM, flash memory, EPROM, or EEPROM, a magnetic disk, a flexible disk, an optical disk, a compact disk, a minidisk, or a DVD.

[0066] When the processing circuit includes at least one dedicated hardware 200, the processing circuit may be realized, for example, as a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination thereof. For example, each function of the notification control device 20 may be realized by a processing circuit. For example, each function of the notification control device 20 may be realized collectively by a processing circuit.

[0067] Some of the functions of the notification control device 20 may be realized by dedicated hardware 200, and the other parts may be realized by software or firmware. For example, the function of calculating the estimated number of passengers who actually disembarked from the car 8 may be realized by a processing circuit as dedicated hardware 200, and functions other than the function of calculating the estimated number of passengers may be realized by at least one processor 100a reading and executing a program stored in at least one memory 100b.

[0068] In this way, the processing circuitry realizes the functions of the notification control device 20 by using hardware 200, software, firmware, or a combination of these.

[0069] Although not shown, the functions of the control panel 19, the call server device 21 and the mobile terminal 22 are also realized by processing circuits equivalent to the processing circuits that realize the functions of the notification control device 20.

[0070] Embodiment 2 Fig. 6 is a block diagram of an elevator system according to embodiment 2. Note that parts that are the same as or equivalent to parts in embodiment 1 are given the same reference numerals, and a description of these parts will be omitted.

[0071] In the second embodiment, the notification control device 20 further includes a congestion determination unit 30.

[0072] The congestion determination unit 30 acquires information about the weight inside the car 8 measured by the scale device 13 via the control panel 19. The congestion determination unit 30 estimates the number of users present inside the car 8 based on the weight inside the car 8. When the car 8 is stopped at the platform 5, the congestion determination unit 30 determines whether the number of users inside the car 8 is equal to or greater than a specified upper limit. Specifically, for example, the specified upper limit is half the rated number of users of the car 8. Note that when the weight inside the car 8 is 50% or more of the rated weight, the congestion determination unit 30 may determine that the number of users inside the car 8 is equal to or greater than the specified upper limit.

[0073] The congestion determination unit 30 determines whether the number of users present inside the car 8 is equal to or less than a specified lower limit number of users. Specifically, for example, the specified lower limit number of users is 20% of the rated number of users of the car 8. Note that when the weight inside the car 8 is equal to or less than 20% of the rated weight, the congestion determination unit 30 may determine that the number of users inside the car 8 is equal to or less than the specified lower limit number of users.

[0074] When the congestion determination unit 30 determines that the number of people inside the car 8 is equal to or greater than a specified upper limit, the car notification unit 26 causes the car notification device 10 to notify the passengers that they are being urged to disembark from the car 8. At this time, the car notification unit 26 may also cause the car notification device 10 to notify the passengers that the request to disembark is being explained, such as "Please cooperate in maintaining social distance."

[0075] When the congestion determination unit 30 determines that the number of passengers present inside the car 8 is equal to or less than a specified lower limit, the car notification unit 26 does not generate the first command, the second command, the third command, or the fourth command. That is, in this case, the car notification unit 26 does not perform the notification operation to encourage passengers to get off the car as shown in the flowchart of Fig. 4 in the first embodiment.

[0076] According to the second embodiment described above, the notification control device 20 includes a congestion determination unit 30. When the notification control device 20 determines that the number of passengers inside the car 8 is equal to or less than the lower limit, the notification control device 20 does not cause the car notification device 10 to notify the expected number of passengers who will get off the car 8 on the first floor while the car is stopped. This makes it possible to prevent the notification operation from being performed when the car is not crowded. As a result, it is possible to reduce the power and other requirements required for the notification operation. It is also possible to prevent unnecessary requests for cooperation from passengers.
