AI Technical Summary
Existing elevator systems fail to account for landing congestion, leading to potential overcrowding at through floors due to passengers unknowingly selecting congested entrances and exits.
The elevator system employs cameras at each landing to assess congestion levels, controlling which car door opens first based on comparative congestion analysis, and uses alarms to guide passengers to less crowded areas.
This approach effectively reduces congestion at through floors by directing passengers to less crowded entrances, enhancing passenger convenience and reducing the risk of overcrowding.

If it is determined that the first landing is more crowded than the second landing corresponding to the second car door on the through floor, the control device determines that the second car door will be the first car door to open on the through floor, and the first landing alarm broadcasts that the second car door will open on the through floor. Furthermore, the control device will open the first car door if a waiting period has elapsed after the second car door has opened on a connecting floor and a landing call has been made from the first landing. If no landing call has been made from the first landing after the second car door has opened on a connecting floor, the control device will close the second car door without opening the first car door. . [Effects of the Invention]
[0007] According to this disclosure, on a through-floor level, the second elevator car door corresponding to the second elevator landing, which is different from the first elevator landing that is determined to be crowded, opens first. This makes it possible to suppress congestion at the elevator landings on the through-floor level. [Brief explanation of the drawing]

[0009] The embodiments for implementing this disclosure will be described with reference to the attached drawings. In each drawing, the same or corresponding parts are denoted by the same reference numerals. The explanation of such parts will be simplified or omitted as appropriate.
[0010] Embodiment 1. Figure 1 is a schematic diagram of a building equipped with the elevator system according to Embodiment 1. Figure 2 is a horizontal cross-sectional view of the elevator car of the elevator system according to Embodiment 1 when it is stopped at a through floor.
[0011] In the elevator system 1 shown in Figure 1, the hoistway 2 penetrates each floor of the building 3. This embodiment shows a machine-room-less elevator system 1.
[0012] The elevator car 4 is installed inside the hoistway 2. The elevator car 4 can move up and down inside the hoistway 2 by a hoisting machine (not shown). The elevator car 4 is a two-way entrance / exit type elevator car. In a two-way entrance / exit type elevator car 4, entrances / exits are provided in two directions. Specifically, the elevator car 4 is provided with two car doors: a front car door 5a and a rear car door 5b.
[0013] The front car door 5a corresponds to one entrance and is provided on one side of the car 4. The front car door 5a comprises a front door panel 6a and a front drive unit 7a. The front door panel 6a is provided so as to be openable and closable at one entrance of the car 4. The front drive unit 7a is a motor. The front drive unit 7a opens or closes the front door panel 6a based on a control command.
[0014] The rear car door 5b corresponds to the other entrance, which is a different entrance from the other entrance, and is located on a side of the car 4 that is different from the front car door 5a. For example, the rear car door 5b is located on the side opposite to one of the other entrances. The rear car door 5b comprises a rear door panel 6b and a rear drive unit 7b. The rear door panel 6b is installed at the other entrance of the car 4 so as to be openable and closable. The rear drive unit 7b is a motor. The rear drive unit 7b opens or closes the rear door panel 6b based on a control command.
[0015] Multiple landings 8 are provided on each floor of the building 3. Each of the multiple landings 8 faces the hoistway 2. In the elevator system 1, through floors are set up. Through floors are floors from which the car 4 can be entered and exited from either of its two entrances. On the through floors, a front landing 8a and a rear landing 8b are provided from among the multiple landings 8. Front landing 8a is the landing corresponding to one entrance of the car 4. Rear landing 8b is the landing corresponding to the other entrance of the car 4.
[0016] A plurality of landing doors 9 are respectively provided at the entrances and exits of a plurality of landings 8. On the through floor, a front landing door 9a and a rear landing door 9b among the plurality of landing doors 9 are provided. The front landing door 9a is provided at the entrance and exit of the front landing 8a. The rear landing door 9b is provided at the entrance and exit of the rear landing 8b.
[0017] A plurality of landing operation panels 10 are provided on the sides of the landing doors 9 at each of the plurality of landings 8. The landing operation panel 10 receives an input of a landing call from a user. On the through floor, a front landing operation panel 10a and a rear landing operation panel 10b among the plurality of landing operation panels 10 are respectively provided at the front landing 8a and the rear landing 8b.
[0018] The elevator system 1 is provided with a front landing camera 11a and a rear landing camera 11b. The front landing camera 11a is provided at the front landing 8a. For example, the front landing camera 11a is provided above the front landing door 9a. The front landing camera 11a can capture an image of the front landing 8a. The rear landing camera 11b is provided at the rear landing 8b. For example, the rear landing camera 11b is provided above the rear landing door 9b. The rear landing camera 11b can capture an image of the rear landing 8b.
[0019] The front landing annunciator 12a is provided at the front landing 8a. For example, the front landing annunciator 12a is a speaker. The rear landing annunciator 12b is provided at the rear landing 8b. For example, the rear landing annunciator 12b is a speaker. The car annunciator 13 is provided inside the car 4. For example, the car annunciator 13 is a speaker. Note that at least one of the front landing annunciator 12a, the rear landing annunciator 12b, and the car annunciator 13 may be a device that notifies a user of information using not only sound but also light, etc. In this case, at least one of the front landing annunciator 12a, the rear landing annunciator 12b, and the car annunciator 13 may include not only a speaker but also an indicator light, a character display panel, etc.
[0020] The control device 14 is installed inside the hoistway 2 as a control panel. The control device 14 can control the elevator system 1 as a whole. Specifically, the control device 14 controls the operation of the elevator car 4. The control device 14 controls the opening and closing operation of the front car door 5a or the rear car door 5b by transmitting control commands to the front drive unit 7a or the rear drive unit 7b. In particular, when the elevator car 4 stops at a through floor, the control device 14 uses the images captured by the front landing camera 11a and the rear landing camera 11b to determine which of the front car door 5a and the rear car door 5b will open first at the through floor.
[0021] As shown in Figure 2, the elevator car 4 is equipped with an elevator control panel 15. The elevator control panel 15 receives destination floor input from passengers in elevator car 4.
[0022] Although not shown in the diagram, on the through floor, the front landing door 9a opens together with the front door panel 6a by receiving force from the front drive unit 7a. On the through floor, the rear landing door 9b opens together with the rear door panel 6b by receiving force from the rear drive unit 7b.
[0023] Next, the control device 14 will be explained using Figure 3. Figure 3 is a block diagram of the elevator system in Embodiment 1.
[0024] As shown in Figure 3, the control device 14 includes an operation control unit 16, a determination unit 17, a door control unit 18, and a notification unit 19.
[0025] The operation control unit 16 controls the operation of the elevator car 4.
[0026] The determination unit 17 acquires image information from the front boarding camera 11a and the rear boarding camera 11b. The determination unit 17 uses the image showing the front boarding 8a to calculate the front boarding congestion level, which is the degree of congestion at the front boarding 8a. The determination unit 17 uses the image showing the rear boarding 8b to calculate the rear boarding congestion level, which is the degree of congestion at the rear boarding 8b. The congestion level is a measure of how crowded boarding 8 is, and is an index value that indicates the density of people present at boarding 8.
[0027] The determination unit 17 compares the congestion level at the front and the congestion level at the back to determine which of the front boarding area 8a and the back boarding area 8b is more crowded. Specifically, if the congestion level at the front is greater than the congestion level at the back, the determination unit 17 determines that the front boarding area 8a is more crowded than the back boarding area 8b. If the congestion level at the back is greater than the congestion level at the front, the determination unit 17 determines that the back boarding area 8b is more crowded than the front boarding area 8a.
[0028] The door control unit 18 controls the opening and closing operations of the front car door 5a and the rear car door 5b. When the car 4 arrives at a through floor, the door control unit 18 determines which of the front car door 5a and the rear car door 5b will open first, using the determination result of the determination unit 17.
[0029] Specifically, if the determination unit 17 determines that the front landing 8a is more crowded than the rear landing 8b, the door control unit 18 decides to open the rear car door 5b, which is the car door corresponding to the less crowded landing, as the second car door. If the determination unit 17 determines that the rear landing 8b is more crowded than the front landing 8a, the door control unit 18 decides to open the front car door 5a as the second car door.
[0030] After the elevator car 4 arrives at the through floor and comes to a stop, the door control unit 18 opens the second elevator car door that it has decided to open first. The door control unit 18 keeps the first elevator car door that is not the second elevator car door that it has decided to open first (the front elevator car door 5a and the rear elevator car door 5b) closed.
[0031] If elevator car 4 is on a through floor and receives a landing call from the first landing control panel of the first landing corresponding to the first car door, the door control unit 18 opens the first car door after a waiting period has elapsed since opening the second car door. When opening the first car door, the door control unit 18 may keep the second car door open or may close the second car door.
[0032] The notification unit 19 controls the content of the notifications made by the front landing notification device 12a, the rear landing notification device 12b, and the elevator car notification device 13.
[0033] Next, using Figure 4, we will explain an example of the congestion level calculated by elevator system 1. Figure 4 is a schematic diagram of an example of a building to which the elevator system in Embodiment 1 is applied. In Figure 4, the control device 14 is not shown.
[0034] As shown in Figure 4, in this example, elevator system 1 is installed to connect the platform level 3X and the ticket gate level 3Y of building 3, which is a station. Platform level 3X is a through level. Ticket gate level 3Y is not a through level. On platform level 3X, the number of people present around the entrances and exits of the front platform 8a and the rear platform 8b changes fluidly in response to events such as train arrivals and departures. If stairs are installed near the front platform 8a, the area around the entrance and exit of the front platform 8a may become temporarily congested with people trying to descend the stairs immediately after a train arrives.
[0035] The control device 14 has a region set for each landing 8 to be used for calculating the degree of congestion. The front region Ea, indicated by a dashed line, is the region corresponding to the front landing 8a. The front region Ea is set to any range including the entrance and exit of the front landing 8a. The rear region Eb, indicated by a dashed line, is the region corresponding to the rear landing 8b. The rear region Eb is set to any range including the entrance and exit of the rear landing 8b.
[0036] The front platform camera 11a captures an image of the area including the front region Ea. The control device 14 uses the image captured by the front platform camera 11a to calculate the number of people inside the front region Ea as the front congestion level of the front platform 8a. The control device 14 calculates the number of people including not only people stationary inside the front region Ea, but also people moving inside the front region Ea. Therefore, the front congestion level includes not only the influence of people stationary near the entrance / exit of the front platform 8a in order to board the train car 4, but also the influence of people waiting for the train near the front platform 8a, and the influence of people moving around the front platform 8a. The control device 14 may also calculate the total area of images other than the ground in the front region Ea as the front congestion level.
[0037] The rear boarding camera 11b captures an image of the area including the rear region Eb. The control device 14 uses the image captured by the rear boarding camera 11b to calculate the number of people inside the rear region Eb as the rear congestion level of the rear boarding 8b. The control device 14 calculates the number of people including not only those stationary inside the rear region Eb, but also those moving inside the rear region Eb. Therefore, the rear congestion level includes not only the influence of people stationary near the entrance / exit of the rear boarding 8b in order to board the car 4, but also the influence of people waiting for the train near the rear boarding 8b, and the influence of people moving around the rear boarding 8b. The control device 14 may also calculate the total area of images in the rear region Eb that are not the ground as the rear congestion level.
[0038] Next, we will explain some of the operations performed by the elevator system 1 using Figure 5. Figure 5 is a flowchart illustrating a partial overview of the operation of the elevator system in Embodiment 1.
[0039] The flowchart in Figure 5 explains the case where the front boarding area 8a is more crowded than the rear boarding area 8b. The crowded front boarding area 8a is also called the first boarding area. The front car door 5a corresponding to the first boarding area is also called the first car door. The less crowded rear boarding area 8b is also called the second boarding area. The rear car door 5b corresponding to the second boarding area is also called the second car door.
[0040] In step S1, the operation control unit 16 determines whether or not the elevator car 4 will arrive at a through floor. Specifically, if the next floor the elevator car 4 will stop at is a through floor, the operation control unit 16 determines that the elevator car 4 will arrive at a through floor. If the next floor the elevator car 4 will stop at is not a through floor, the operation control unit 16 determines that the elevator car 4 will not arrive at a through floor.
[0041] If it is determined in step S1 that elevator car 4 will not reach the through floor, the operation in step S1 is repeated.
[0042] If it is determined in step S1 that the elevator car 4 has arrived at the through floor, the operation in step S2 is performed. In step S2, the determination unit 17 acquires image information of the first landing from the front landing camera 11a, which is the first camera that images the first landing. The determination unit 17 acquires image information of the second landing from the rear landing camera 11b, which is the second camera that images the second landing. Using the acquired images, the determination unit 17 calculates the first congestion level, which is the congestion level of the first landing, and the second congestion level, which is the congestion level of the second landing.
[0043] Subsequently, in step S3, the determination unit 17 compares the first congestion level and the second congestion level and determines that the first congestion level is greater. In this case, the determination unit 17 determines that the first landing is more crowded than the second landing. The door control unit 18 determines that the second car door will be the first car door to open on the through floor.
[0044] Subsequently, in step S4, the notification unit 19 notifies the car alarm 13 that the rear car door 5b, which is the first car door to open, will open at the through floor. The notification unit 19 also notifies the front landing alarm 12a, which is the first landing alarm installed at the first landing, that the rear car door 5b will open at the through floor. The notification unit 19 also notifies the rear landing alarm 12b, which is the second landing alarm installed at the second landing, that the rear car door 5b will open at the through floor.
[0045] Subsequently, in step S5, the elevator car 4 stops at the through floor. The door control unit 18 opens the second elevator car door, which has been determined to be the first elevator car door to open. The door control unit 18 maintains the closed state of the first elevator car door.
[0046] Subsequently, in step S6, the operation control unit 16 determines whether or not a landing call has been made from the first landing. Specifically, the operation control unit 16 determines whether or not a landing call has been made from the front landing control panel 10a, which is the first landing control panel installed at the first landing. Alternatively, the door control unit 18 may determine whether or not a landing call has been made from the first landing instead of the operation control unit 16.
[0047] If it is determined in step S6 that no landing call has been made at the first landing, the operation in step S7 is performed. In step S7, after a specified time has elapsed, the door control unit 18 closes all the car doors. The operation control unit 16 departs car 4 from the connecting floor. After that, the operation of the flowchart is completed.
[0048] If it is determined in step S6 that a landing call has been made at the first landing, the operation in step S8 is performed. In step S8, the door control unit 18 determines whether a prescribed waiting time has elapsed since the second car door opened.
[0049] If it is determined in step S8 that the waiting time has not elapsed, the operation in step S8 is repeated.
[0050] If it is determined in step S8 that the waiting time has elapsed, the operation in step S9 is performed. In step S9, the door control unit 18 opens a first cage door that is different from the first cage door that is opened. After that, the operation in step S7 is performed. After that, the operation of the flowchart is completed.
[0051] Furthermore, while waiting for the waiting time to elapse in step S8, the notification unit 19 may cause the first landing notification device to notify that the first car door will open soon.
[0052] Furthermore, if the rear boarding platform 8b is more crowded than the front boarding platform 8a, the more crowded rear boarding platform 8b will also be referred to as boarding platform 1. In this case, the less crowded front boarding platform 8a will also be referred to as boarding platform 2.
[0053] According to Embodiment 1 described above, the elevator system 1 has two entrances / exits in the car 4. The car 4 is equipped with a front car door 5a and a rear car door 5b, which are the first and second car doors. The control device 14 determines which car door to open first on a through floor according to the degree of congestion at the landing on that floor. As a result, the elevator system 1 can allow passengers from the car 4 to disembark from the less crowded landing. Consequently, congestion at the landing on the through floor can be suppressed. In addition, passenger convenience can be improved.
[0054] In particular, to prevent the spread of infectious diseases transmitted through droplets, it is important to avoid creating situations where people are crowded together as much as possible. Passengers in car 4 can disembark at the less crowded boarding area on the connecting floor. As a result, the spread of infectious diseases can be suppressed. In addition, when it is desired to distribute the flow of people fluidly within a building, the flow of people disembarking from car 4 can be distributed.
[0055] Furthermore, the elevator system 1 is further equipped with a first camera and a second camera, which are a front landing camera 11a and a rear landing camera 11b. The control device 14 calculates the first congestion level of the first landing and the second congestion level of the second landing, and quantifies the degree of congestion. In particular, the control device 14 uses the number of people in the first area as the first congestion level. In particular, the control device 14 uses the number of people in the second area as the second congestion level. As a result, the elevator system 1 can more accurately determine the degree of congestion in the first landing and the second landing.
[0056] In addition, in the flowchart of Figure 5, the operation of step S6 may be omitted, and the operation of step S8 may be performed after the operation of step S5. In this case, the door control unit 18 of the control device 14 may open the first car door after the waiting time has elapsed since the second car door was opened, regardless of whether or not a landing call has been made at the first landing. As a result, passengers waiting at the first landing can board the car 4 without having to move toward the second car door.
[0057] Furthermore, the control device 14 opens the first car door when a waiting time has elapsed while a call for a passenger has been made from the first landing control panel. Even in this case, passengers waiting at the first landing can board the car 4 without having to move to the second car door. In addition, it is possible to prevent the first car door from being opened when there are no passengers waiting at the first landing. As a result, the operational efficiency of the car 4 can be improved.
[0058] Furthermore, elevator system 1 may also be a system that includes a machine room.
[0059] Furthermore, the two entrances to the cage 4 do not necessarily have to face each other. For example, in cage 4, the other entrance may be located on a side adjacent to the side of cage 4 on which one entrance is located.
[0060] Furthermore, the determination unit 17 and the door control unit 18 of the control device 14 may be provided in a door controller that integrates and controls the front drive unit 7a and the rear drive unit 7b provided in the car 4. The door controller may also be provided with an notification unit 19.
[0061] The front boarding camera 11a and the rear boarding camera 11b may capture video, which is a series of images rather than still images, and transmit the video information to the control device 14. The determination unit 17 of the control device 14 may calculate the degree of congestion based on the video information.
[0062] Next, an example of the hardware constituting the control device 14 will be explained using Figure 6. Figure 6 is a hardware configuration diagram of the control device for the elevator system in Embodiment 1.
[0063] Each function of the control device 14 can be realized by a processing circuit. For example, the processing circuit comprises at least one processor 100a and at least one memory 100b. For example, the processing circuit comprises at least one dedicated hardware 200.
[0064] When the processing circuit comprises at least one processor 100a and at least one memory 100b, each function of the control device 14 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 at least one memory 100b. At least one processor 100a realizes each function of the control device 14 by reading and executing the program stored in at least one memory 100b. At least one processor 100a is also called a central processing unit, processing unit, arithmetic unit, microprocessor, microcomputer, or DSP. For example, at least one memory 100b is a non-volatile or volatile semiconductor memory such as RAM, ROM, flash memory, EPROM, EEPROM, magnetic disk, flexible disk, optical disk, compact disk, minidisc, DVD, etc.
[0065] If the processing circuit includes at least one dedicated hardware 200, the processing circuit may be implemented as, for example, 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 control unit 14 may be implemented by a processing circuit. For example, each function of the control unit 14 may be implemented together by a processing circuit.
[0066] For each function of the control device 14, some may be implemented by dedicated hardware 200, and others by software or firmware. For example, the function for calculating congestion may be implemented by a processing circuit as dedicated hardware 200, while functions other than the function for calculating congestion may be implemented by at least one processor 100a reading and executing a program stored in at least one memory 100b.
[0067] In this way, the processing circuit realizes each function of the control device 14 using hardware 200, software, firmware, or a combination thereof. [Industrial applicability]
