[0011] 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.

[0012] Embodiment 1 FIG. 1 is a configuration diagram of a building to which the elevator system according to the first embodiment is applied.

[0013] 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. One of the plurality of landings 5 ​​is shown in Fig. 1.

[0014] The hoisting machine 6 is provided in the machine room 4. The main ropes 7 are wound around the hoisting machine 6. The car 8 is provided inside the hoistway 3. The car 8 is hung on one side of the main ropes 7. The counterweight 9 is provided inside the hoistway 3. The counterweight 9 is hung on the other side of the main ropes 7.

[0015] The car 8 is provided with a car door 10, a door detector 11, and an alarm 12. The car door 10 is provided at the entrance / exit of the car 8. The door detector 11 is provided above the car door 10. The door detector 11 can detect whether the car door 10 is open or closed. For example, the alarm 12 is a speaker. The alarm 12 is provided inside the car 8.

[0016] The control panel 13 is provided in the machine room 4. The control panel 13 is electrically connected to the hoisting machine 6 and the devices provided in the car 8. The control panel 13 can control the elevator system 1 as a whole.

[0017] The elevator system 1 includes a notification system 20. The notification system 20 creates information to urge passengers inside the car 8 to maintain social distance, i.e., to keep passengers apart by a specified distance. The notification system 20 includes a piezoelectric detector 21 and a notification device 22.

[0018] The piezoelectric detector 21 is provided on the floor of the car 8. For example, the piezoelectric detector 21 is laid over the entire floor of the car 8. The piezoelectric detector 21 can detect pressure received from an object in contact with the upper surface, which is the floor. The piezoelectric detector 21 can emit a signal indicating the position where the pressure is detected.

[0019] A plurality of markers 23 are provided on the upper surface of the piezoelectric detection device 21. For example, the plurality of markers 23 are figures drawn on the upper surface of the piezoelectric detection device 21. Specifically, the plurality of markers 23 are figures indicating where passengers should stand, such as "Please get on here." The plurality of markers 23 are arranged at a specified distance from each other.

[0020] The plurality of markers 23 may be mats placed on the upper surface of the piezoelectric detection device 21. For example, the plurality of markers 23 may have written thereon information specifying the standing position of the passenger. In this case, the piezoelectric detection device 21 can detect pressure received from an object in contact with the upper surface via the plurality of markers 23.

[0021] For example, the alarm device 22 is provided in the machine room 4. The alarm device 22 is electrically connected to the control panel 13. Although not shown, the alarm device 22 is electrically connected to the piezoelectric detector 21.

[0022] When the elevator system 1 is operating normally, the hoist 6 is driven to rotate based on commands from the control panel 13. The main rope 7 moves following the rotation of the hoist 6. The car 8 and counterweight 9 move up and down in opposite directions following the movement of the main rope 7. When the car 8 arrives at the landing 5, the car door 10 opens. The door detector 11 transmits a signal indicating the open state of the car door 10 to the control panel 13. The alarm device 22 receives the signal indicating the open state of the car door 10 via the control panel 13.

[0023] Thereafter, a plurality of passengers board the car 8. The control panel 13 controls the car 8 to move to the next landing 5. Specifically, the control panel 13 closes the car door 10 and then rotates the hoist 6.

[0024] When the car door 10 is closed, the door detector 11 transmits a signal indicating the closed state of the car door 10 to the control panel 13. The alarm device 22 receives the signal indicating the closed state of the car door 10 via the control panel 13. When the alarm device 22 receives the signal indicating the closed state of the car door 10, the alarm system 20 determines whether the distance between passengers is greater than a specified distance, i.e., whether the passengers are maintaining social distance.

[0025] Specifically, the piezoelectric detection device 21 transmits a signal indicating the position of pressure received from each of the multiple passengers to the alarm device 22. If any of the multiple markers 23 is empty and there is a passenger who is not standing on one of the multiple markers 23, the alarm device 22 determines that the passenger is not maintaining social distance based on the signal received from the piezoelectric detection device 21. In this case, the alarm device 22 transmits a first alarm command to the control panel 13 to notify the passenger that they should move onto the marker 23. When the control panel 13 receives the first alarm command, it causes the alarm 12, which is a speaker, to issue a voice message such as "Please move onto the marker."

[0026] When there are passengers on all the markers 23 but there is a passenger who is not standing on a marker 23, the alarm device 22 determines, based on the signal received from the piezoelectric detection device 21, that the number of passengers inside the car 8 exceeds the number appropriate for maintaining social distancing. In this case, the alarm device 22 transmits a second alarm command to the control panel 13 to notify passengers that they should disembark from the car 8 at the next platform 5. When the control panel 13 receives the second alarm command, it causes the alarm 12 to issue a voice message such as "Those who cannot get on the marker are requested to disembark."

[0027] Next, the piezoelectric detector 21 will be described with reference to FIG. Fig. 2 is a top view of the piezoelectric detection device of the elevator system in embodiment 1. Note that the illustration of the plurality of markers 23 is omitted in Fig. 2.

[0028] As shown in FIG. 2, the piezoelectric detection device 21 includes a plurality of piezoelectric detectors 21a and a transmitter 21b.

[0029] For example, each of the plurality of piezoelectric detectors 21a is a thin piezoelectric sensor. For example, the piezoelectric detector 21a has a square detection surface with each side measuring 2 cm. When pressure is applied to the detection surface, the piezoelectric detector 21a passes a current. As shown in FIG. 2, the plurality of piezoelectric detectors 21a are closely spaced on the floor of the car 8. In other words, the plurality of piezoelectric detectors 21a form the floor of the car 8. The plurality of piezoelectric detectors 21a are divided into a plurality of sections according to their installation positions.

[0030] Although not shown, for example, transmitter 21b is provided under the floor of car 8. Transmitter 21b is electrically connected to alarm device 22. Transmitter 21b is electrically connected to multiple piezoelectric detectors 21a. Transmitter 21b can detect current from piezoelectric detector 21a. When transmitter 21b detects current from one of the multiple piezoelectric detectors 21a, it transmits a signal to transmitter 21b indicating that the piezoelectric detector 21a has detected pressure. Note that transmitter 21b may also be provided on top of car 8.

[0031] Next, the sections set in the piezoelectric detector 21 will be described with reference to FIG. FIG. 3 is a top view of the piezoelectric detection device of the elevator system according to the first embodiment.

[0032] As shown in FIG. 3, the plurality of piezoelectric detectors 21a on the floor surface of the car 8 are divided into a plurality of sections. The plurality of sections includes a first section S1 and a second section S2. For example, the plurality of piezoelectric detectors 21a are set up in nine square sections. That is, the plurality of piezoelectric detectors 21a are set up in a grid pattern of three rows and three columns. In this case, the nine sections consist of four first sections and five second sections. For example, one section is a square with one side measuring 50 cm.

[0033] The first sections S1 are sections indicated by diagonal lines in FIG. 3. Specifically, the four first sections S1 are sections at the four corners of the nine sections. The multiple first sections S1 are not adjacent to each other. That is, two first sections S1 do not share the same side. Note that two first sections S1 may be adjacent to each other diagonally. That is, two first sections S1 may share a vertex.

[0034] The multiple first sections S1 are spaced apart by more than a specified distance. Here, the distance between two first sections S1 is the distance between the center of one first section S1 and the center of another first section S1. The specified distance is set to a distance that allows social distancing to be maintained inside the car 8. For example, the specified distance is 1 meter.

[0035] The second section S2 is a section among the multiple sections that is not one of the first sections S1. For example, the second section S2 is set to be located between two first sections S1.

[0036] 3 are provided inside the first sections S1, respectively. That is, the positions of the markers 23 correspond to the positions of the first sections S1.

[0037] Next, the notification device 22 will be described with reference to FIG. FIG. 4 is a block diagram of the elevator system according to the first embodiment.

[0038] As shown in FIG. 4, the notification device 22 includes a receiving unit 24, a position detecting unit 25, and a notification unit .

[0039] The receiving unit 24 receives control information for the elevator system 1 from the control panel 13. For example, the receiving unit 24 receives an output signal of the door detector 11 from the control panel 13. The receiving unit 24 receives a signal from the transmitter 21b of the piezoelectric detection device 21.

[0040] The position detection unit 25 identifies the position of the piezoelectric detector 21a corresponding to the signal received by the receiving unit 24 from the transmitter 21b. The position detection unit 25 identifies the position of the piezoelectric detector 21a corresponding to the signal on the floor of the car 8. In other words, when a passenger gets on the piezoelectric detector 21a and a signal is output from the piezoelectric detector 21a, the position detection unit 25 identifies the position of the passenger on the floor of the car 8.

[0041] The position detection unit 25 detects whether the identified passenger is located in the first section or the second section. When there are multiple passengers inside the car 8, the position detection unit 25 detects the section in which each of the multiple passengers is located.

[0042] For example, when the receiving unit 24 receives a signal from the piezoelectric detector 21a that belongs to any one of the first sections, the position detecting unit 25 detects that the passenger is located in that first section.

[0043] The notification unit 26 generates a first notification command or a second notification command based on the information on the passenger's position detected by the position detection unit 25. Specifically, the notification unit 26 determines whether or not a passenger is located in the second zone. If the notification unit 26 determines that a passenger is located in the second zone, it determines whether or not there is a first zone among the multiple first zones in which no passenger is located. If the notification unit 26 determines that there is a first zone in which no passenger is located, it generates a first notification command. If the notification unit 26 determines that there is no first zone in which no passenger is located, that is, that passengers are located in all of the first zones, it generates a second notification command. When the notification unit 26 generates the first notification command or the second notification command, it transmits the generated command to the control panel 13.

[0044] The notification unit 26 determines whether or not the car door 10 (not shown in Fig. 4) is in a closed state based on the output signal of the door detector 11 received by the receiving unit 24. If the notification unit 26 determines that the car door 10 is not in a closed state, the notification unit 26 does not generate a first notification command. Specifically, for example, if the notification unit 26 determines that the car door 10 is not in a closed state, the notification unit 26 does not perform an operation to determine whether or not to make the car a second section.

[0045] Next, the process performed by the notification system 20 will be described with reference to FIG. FIG. 5 is a flowchart for explaining an outline of the processing of the notification system of the elevator system according to the first embodiment.

[0046] In FIG. 5, when the notification system 20 receives information from the control panel 13 that the car 8 has arrived at the hall 5, it starts the processing shown in the flowchart.

[0047] In step S01, the notification system 20 determines whether the car door 10 is in a closed state.

[0048] If it is determined in step S01 that the car door 10 is not in the closed state, the notification system 20 repeats the operation of step S01.

[0049] If it is determined in step S01 that the car door 10 is in the closed state, the notification system 20 performs the operation of step S02. In step S02, the notification system 20 determines whether or not a passenger is located in the second section.

[0050] If it is determined in step S02 that no passenger is located in the second section, the notification system 20 ends the processing shown in the flowchart.

[0051] If it is determined in step S02 that a passenger is located in the second section, the notification system 20 performs the operation of step S03. In step S03, the notification system 20 determines whether or not there is a first section among the multiple first sections in which no passenger is located.

[0052] If it is determined in step S03 that there is a first section where no passenger is located, the notification system 20 performs the operation of step S04. In step S04, the notification system 20 generates a first notification command and transmits it to the control panel 13. Thereafter, the notification system 20 ends the processing shown in the flowchart.

[0053] In step S03, if it is determined that there is no first section among the plurality of first sections in which no passengers are located, that is, if it is determined that passengers are located in all of the first sections, the notification system 20 performs the operation of step S05. In step S05, the notification system 20 creates a second notification command and transmits it to the control panel 13. Thereafter, the notification system 20 ends the processing shown in the flowchart.

[0054] According to the first embodiment described above, the elevator system 1 includes a car 8, an alarm 12, and an alarm system 20. The alarm system 20 includes a piezoelectric detector 21 and an alarm device 22. The alarm device 22 includes a receiver 24, a position detector 25, and an alarm unit 26. When the alarm device 22 determines, based on the signal from the piezoelectric detector 21, that a second section S2 where a passenger is located exists and that a first section S1 where no passenger is located exists, the alarm device 22 generates a first alarm command to cause the alarm 12 to issue an alarm urging the passenger to move to the first section S1. For example, passengers who hear the alarm move to a position where social distancing can be maintained. This prevents passengers from getting too close to each other.

[0055] Furthermore, when the alarm device 22 determines that there is a second section S2 where passengers are located and that passengers are located in all of the first sections S1, it generates a second alarm command. The second alarm command is a command to issue a warning to urge passengers to disembark from the car 8. This makes it possible to prevent a number of passengers who are unable to maintain an appropriate distance from continuing to move in the car 8. As a result, it is possible to prevent passengers from getting too close to each other.

[0056] The elevator system 1 also includes a door detector 11. The door detector 11 transmits a signal indicating the state of the door of the car 8 to the alarm device 22. When the door of the car 8 is in an open state, the alarm device 22 does not generate a first alarm command. This makes it possible to prevent an alarm from being issued while a passenger is getting on or off the car 8. As a result, it is possible to prevent unnecessary alarms from being issued.

[0057] The operation of step S01 in the flowchart of FIG. 5 may be performed by the alarm unit 26 after step S03 and before step S04, rather than before step S02. At this time, if the alarm device 22 determines that the door of the car 8 is not in an open state, it generates a first alarm command. If the alarm device 22 determines that the door of the car 8 is in an open state, it ends the processing of the flowchart without generating the first alarm command. Furthermore, the operation of step S01 may be performed after step S03 and before step S05. At this time, if the alarm device 22 determines that the door of the car 8 is not in an open state, it generates a second alarm command. If the alarm device 22 determines that the door of the car 8 is in an open state, it ends the flowchart without generating the second alarm command.

[0058] The piezoelectric detecting device 21 also includes a plurality of piezoelectric detectors 21a and a transmitter 21b, and can transmit the pressure detected by the piezoelectric detectors 21a as a signal via the transmitter 21b.

[0059] Furthermore, the area of ​​the detection surface of the piezoelectric detector 21a is smaller than the areas of the first section S1 and the second section S2. The first section S1 is set in some regions of the plurality of piezoelectric detectors 21a. The second section S2 is set in some regions of the remaining plurality of piezoelectric detectors 21a where the first section S1 is not set. This improves the accuracy of detecting whether a passenger is located in the first section S1 or the second section S2.

[0060] The piezoelectric detection device 21 may be a smart fabric that detects pressure. Specifically, the piezoelectric detection device 21 may include a fabric and a transmitter. The fabric is made of fibers that change voltage when pressure is applied. The fabric is provided on the floor of the car 8. The transmitter detects the position on the fabric where pressure is applied based on the change in voltage of the fabric fibers. The transmitter transmits a signal indicating that the fabric has received pressure and a signal indicating the position on the fabric where pressure is applied to the alarm device 22. This allows the piezoelectric detection device 21 to be provided at low cost.

[0061] The alarm 12 may have a display for displaying information.

[0062] The plurality of markers 23 may be mats placed on the upper surface of the piezoelectric detection device 21. For example, the plurality of markers 23 may have written thereon information specifying the standing position of the passenger. In this case, the piezoelectric detection device 21 can detect pressure received from an object in contact with the upper surface via the plurality of markers 23.

[0063] The notification device 22 may be provided inside the control panel 13.

[0064] The operation of step S01 in the flowchart of FIG. 5 may be performed by the alarm unit 26 after step S03 and before step S04, rather than before step S02. At this time, if the alarm device 22 determines that the door of the car 8 is not in an open state, it generates a first alarm command. If the alarm device 22 determines that the door of the car 8 is in an open state, it ends the processing of the flowchart without generating the first alarm command. Furthermore, the operation of step S01 may be performed after step S03 and before step S05. At this time, if the alarm device 22 determines that the door of the car 8 is not in an open state, it generates a second alarm command. If the alarm device 22 determines that the door of the car 8 is in an open state, it ends the flowchart without generating the second alarm command.

[0065] Next, an example of hardware constituting the notification device 22 will be described with reference to FIG. FIG. 6 is a hardware configuration diagram of the notification device of the elevator system according to the first embodiment.

[0066] Each function of the alarm device 22 may be realized by a processing circuit. For example, the processing circuit may include at least one processor 100a and at least one memory 100b. For example, the processing circuit may include at least one dedicated hardware 200.

[0067] When the processing circuit includes at least one processor 100a and at least one memory 100b, the functions of the alarm device 22 are implemented 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 implements the functions of the alarm device 22 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 unit, 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.

[0068] 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 alarm device 22 may be realized by a processing circuit. For example, each function of the alarm device 22 may be realized collectively by a processing circuit.

[0069] Some of the functions of the alarm device 22 may be realized by dedicated hardware 200, and the other parts may be realized by software or firmware. For example, the function of transmitting the first alarm command to the control panel 13 may be realized by a processing circuit as the dedicated hardware 200, and functions other than the function of transmitting the first alarm command to the control panel 13 may be realized by at least one processor 100a reading and executing a program stored in at least one memory 100b.

[0070] In this way, the processing circuitry realizes the functions of the notification device 22 by hardware 200, software, firmware, or a combination thereof.

[0071] Embodiment 2 Fig. 7 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.

[0072] As shown in Fig. 7, in the second embodiment, the notification device 22 further includes a direction determination unit 27. The notification device 22 generates a command to notify a passenger inside the car 8 (not shown in Fig. 7) of a third notification command to urge the passenger to face a specified direction. For example, the specified direction is a direction to face one of the sides of the car 8 on which the car door 10 is provided.

[0073] The direction determination unit 27 determines the direction in which the passenger in the car 8 is facing, based on the signal received by the receiving unit 24 from the transmitter 21b. Specifically, the direction determination unit 27 identifies two pressure ranges that are closer than the specified foot determination distance, based on the signal from the transmitter 21b. Then, the direction determination unit 27 identifies a first pressure range that has a larger area of ​​the two pressure ranges. The direction determination unit 27 identifies a second pressure range that has a smaller area of ​​the two pressure ranges.

[0074] The direction determination unit 27 determines that the direction from the position of the second pressure range to the position of the first pressure range is the direction in which the passenger corresponding to the two pressure ranges faces.

[0075] The notification unit 26 creates a third notification command based on the information on the direction of the passengers determined by the direction determination unit 27. Specifically, the notification unit 26 determines whether or not there are any passengers in the car 8 who are facing a direction other than the specified direction based on the information on the direction of the passengers determined by the direction determination unit 27. If it is determined that there are any passengers who are facing a direction other than the specified direction, the notification unit 26 creates a third notification command. In this case, the notification unit 26 transmits the third notification command to the control panel 13.

[0076] When the control panel 13 receives the third notification command, it causes the alarm 12 to issue a voice message such as "Please face the door to prevent droplets from scattering."

[0077] Next, an example in which the direction determining unit 27 determines the direction will be described with reference to FIG. Fig. 8 is a diagram showing an outline of a piezoelectric detection device of an elevator system according to embodiment 2. Note that in Fig. 8, transmitter 21b and notification device 22 are omitted from illustration.

[0078] 8 shows a foot shape X. The foot shape X represents the shape of the sole of one of the passenger's shoes.

[0079] Some of the piezoelectric detectors 21a receive pressure from one foot of the passenger within the range of foot shape X. Among the piezoelectric detectors 21a, the piezoelectric detector 21a that detected the pressure is indicated by diagonal lines. The transmitter 21b transmits a signal corresponding to the piezoelectric detector 21a indicated by diagonal lines to the alarm device 22.

[0080] Based on the signal from the transmitter 21b, the direction determination unit 27 in the alarm device 22 divides the range indicated by the footprint X, which is the pressure applied by the passenger to the plurality of piezoelectric detectors 21a, into a first pressure range Y and a second pressure range Z. Specifically, for example, the direction determination unit 27 identifies the pressure range in which the number of piezoelectric detectors 21a that detected the pressure is greater as the first pressure range Y. The direction determination unit 27 identifies the pressure range in which the number of piezoelectric detectors 21a that detected the pressure is less as the second pressure range Z.

[0081] Thereafter, the direction determination unit 27 determines that the direction d from the position of the second pressure range Z to the position of the first pressure range Y is the direction in which the passenger corresponding to that pressure range faces.

[0082] Next, the process performed by the notification system 20 in the second embodiment will be described with reference to FIG. FIG. 9 is a flowchart for explaining an outline of the processing of the notification system of the elevator system according to the second embodiment.

[0083] The operations performed in steps S11 to S15 of the flowchart shown in FIG. 9 are the same as the operations performed in steps S01 to S05 of the flowchart shown in FIG.

[0084] If it is determined in step S12 that no passenger is located in the second section, if the operation of step S14 is performed, or if the operation of step S15 is performed, the notification system 20 performs the operation of step S16.

[0085] In step S16, the notification system 20 determines whether or not there is any passenger among the passengers in the car 8 who is facing a direction other than the specified direction.

[0086] If it is determined in step S16 that there is no passenger facing a direction other than the specified direction, the notification system 20 ends the processing shown in the flowchart.

[0087] If it is determined in step S16 that there is a passenger facing a direction other than the specified direction, the notification system 20 performs the operation of step S17. In step S17, the notification system 20 creates a third notification command and transmits it to the control panel 13. Thereafter, the notification system 20 ends the processing shown in the flowchart.

[0088] According to the second embodiment described above, the alarm device 22 further includes a direction determination unit 27. The alarm device 22 determines the direction in which the passenger is facing. When the alarm device 22 determines that there is a passenger who is not facing the specified direction, it generates a third alarm command to notify the passenger to face the specified direction. From the perspective of preventing the spread of infectious diseases that may be transmitted by droplets, it is desirable for passengers to board the car 8 so that they do not face each other. The alarm device 22 can prompt passengers to face in a direction that will prevent them from facing each other. This makes it possible to suppress the spread of infectious diseases.

[0089] Furthermore, the alarm device 22 identifies a first pressure range and a second pressure range. The alarm device 22 determines the direction in which the passenger is facing based on the position of the first pressure range and the position of the second pressure range. Therefore, the alarm device 22 can accurately determine the direction in which the passenger is facing based on the signal from the piezoelectric detection device 21.

[0090] In addition, even if the two pressure ranges are one pressure range that are not separated from each other, the direction determination unit 27 may decompose the one pressure range into two pressure ranges and identify a first pressure range and a second pressure range.
