Description

Technical Field

[0001] This invention relates to elevator control systems. Background Technology

[0002] In existing control systems for wheelchair-accessible elevators, a camera is installed above the car entrance / exit. The images captured by the camera are analyzed by an image analysis device. The image analysis device determines whether a wheelchair user is present at the landing. Even if it is determined that no wheelchair user is present at the landing, if the wheelchair-only call button inside the car is activated, the control device registers the same call as if a regular call button had been activated (for example, see Patent Document 1).

[0003] Patent Document 1: Japanese Patent Application Publication No. 2019-151453

[0004] In the existing control system of wheelchair-accessible elevators as described above, even if the dedicated wheelchair call button is pressed, a regular call is also registered even if the user is not a wheelchair user. Therefore, regular calls are also registered for users other than wheelchair users, such as those using strollers or baby carriages, who wish to have the same control as wheelchair users, reducing convenience. Summary of the Invention

[0005] The present invention was made to solve the above-mentioned problems, and its purpose is to provide an elevator control system that can not only detect wheelchair users, but also more accurately detect wheelchair-equipped users, including wheelchair users, thereby improving convenience.

[0006] The elevator control system of the present invention includes: an acceleration sensor that detects the acceleration of movement of the car compartment and sends an acceleration detection signal; an information processing unit that receives and processes the acceleration detection signal, thereby determining whether a wheelchair-equipped user exists among at least one user moving between a landing and the car compartment; and an operation control unit that performs control related to the operation of the car based on the determination result of the information processing unit. The information processing unit stores specific vibration information, which is information related to the vibration generated in the car compartment when a wheelchair-equipped user moves between a landing and the car compartment. The information processing unit determines whether a wheelchair-equipped user exists by comparing the vibration-related value of the car compartment obtained by processing the acceleration detection signal with the specific vibration information.

[0007] The elevator control system according to the present invention can not only detect wheelchair users, but also more accurately detect wheelchair-equipped users, including wheelchair users, thereby improving convenience. Attached Figure Description

[0015] 8: Car; 11: Car room; 12: Car door; 16: Dedicated button on the landing side; 18: Dedicated button on the car side; 21: Operation control unit; 22: Accelerometer sensor; 23: Information processing unit. Detailed Implementation

[0016] Hereinafter, Embodiment 1 will be described with reference to the accompanying drawings.

[0017] Implementation Method 1

[0018] Figure 1 This is a schematic structural diagram of the elevator device according to Embodiment 1, showing a machine-room-less elevator. In the figure, a support beam 2 and a main control device 5 are provided at the top of the shaft 1.

[0019] The traction machine 3 is supported on the support beam 2. The traction machine 3 includes a drive sheave 4, a traction machine motor (not shown), and a traction mechanism brake (not shown). The traction machine motor 13 rotates the drive sheave 4. The traction mechanism brake keeps the drive sheave 4 stationary. Furthermore, the traction mechanism brakes the rotation of the drive sheave 4.

[0020] The suspension body 7 is wound around the drive pulley 4. Multiple ropes or multiple belts are used as the suspension body 7.

[0021] The car 8 and counterweight 9 are suspended by the suspension body 7 and move up and down within the hoistway 1 by rotating the drive sheave 4. The main control unit 5 controls the raising and lowering of the car 8 by controlling the traction machine 3.

[0022] Inside hoistway 1, there is a pair of car guide rails (not shown) and a pair of counterweight guide rails (not shown). The pair of car guide rails guide the car 8 to rise and fall. The pair of counterweight guide rails guide the counterweight 9 to rise and fall.

[0023] The car 8 has a car frame 10, a car compartment 11, and a car door 12. The suspension body 7 is connected to the car frame 10. The car compartment 11 is supported by the car frame 10. A car entrance and exit are provided in the car compartment 11. The car door 12 opens and closes the car entrance and exit.

[0024] A door controller 13 is installed on the car 8. The door controller 13 controls the opening and closing of the car door 12.

[0025] Landing doors 14 are installed at each of the multiple floors. At each floor, the landing doors 14 open and close the entrances and exits. In addition, at each floor, the landing doors 14 open and close in conjunction with the car doors 12 when the car 8 stops at a floor.

[0026] At each floor, there are multiple floor operation buttons for calling the elevator car 8. Each floor's multiple floor operation buttons include one or two standard floor buttons 15 and one or two dedicated floor buttons 16. The dedicated floor buttons 16 are for wheelchair users.

[0027] Inside the car compartment 11, there are multiple in-car operation buttons for specifying the destination floor. These buttons include multiple standard car-side buttons 17 and at least one dedicated car-side button 18. The dedicated car-side button 18 is for wheelchair users.

[0028] Figure 2 This is a block diagram showing the elevator control system according to Embodiment 1. The elevator control system includes an operation control unit 21, an acceleration sensor 22, and an information processing unit 23. The operation control unit 21 includes a main control device 5 and a door controller 13.

[0029] Figure 2 Although not shown in the figure, noise that is not needed for signal processing is removed in the acceleration sensor 22 or the information processing unit 23 as required.

[0030] Although Figure 1 The details are omitted, but the acceleration sensor 22 is disposed in the car compartment 11. More preferably, the acceleration sensor 22 is disposed in the center of the lower surface of the floor portion of the car compartment 11. Furthermore, the acceleration sensor 22 has at least one axis, detects the acceleration of the movement of the car compartment 11 relative to the car frame 10, and sends an acceleration detection signal.

[0031] Although Figure 1The details are omitted, but the information processing unit 23 is, for example, installed on the car 8. Furthermore, the information processing unit 23 receives and processes acceleration detection signals from the acceleration sensor 22. Thus, the information processing unit 23 determines whether a wheelchair-equipped user exists among at least one user moving between the landing and the car compartment 11.

[0032] Wheelchair equivalent users include wheelchair users and users who should perform the same controls related to the operation of the car 8 as wheelchair users. Specifically, wheelchair equivalent users include wheelchair users, trolley users, shopping cart users, stroller users, wheeled suitcase users, and bicycle users, etc.

[0033] In addition, the information processing unit 23 can also determine, based on the acceleration detection signal, whether there is a user deliberately shaking the car room 11 during the movement of the car 8.

[0034] The information processing unit 23 has a transmission and reception unit 23a, a signal processing unit 23b, a comparison and determination unit 23c, an information storage unit 23d, and a learning unit 23e as functional blocks.

[0035] The transmitting and receiving unit 23a receives acceleration detection signals from the accelerometer 22. Furthermore, the transmitting and receiving unit 23a transmits and receives signals with the operation control unit 21.

[0036] Specific vibration information is stored in the information storage unit 23d. This specific vibration information relates to the vibrations generated in the car compartment 11 when a wheelchair-equipped user moves between the landing and the car compartment 11. In Embodiment 1, the specific vibration information relates to the frequency of vibrations in the car compartment 11. Furthermore, the specific vibration information is information obtained in advance through AI learning, i.e., machine learning.

[0037] Learning section 23e, for example, obtains specific vibration information through machine learning after the elevator installation is completed and before the start of normal service. Machine learning, for example, is supervised learning.

[0038] In supervised learning, multiple users, including wheelchair-equipped users and ordinary users who are not wheelchair-equipped users, are designated as samples. Furthermore, the acceleration detection signal obtained from the accelerometer 22 when each sample moves between the landing and the car compartment 11 is designated as input data, and whether each sample is an ordinary user or a wheelchair-equipped user is designated as output data.

[0039] After the elevator system begins normal service, the signal processing unit 23b processes and performs Fourier transform on the acceleration detection signal from the acceleration sensor 22, thereby determining the frequency of vibration of the car compartment 11 as a value related to the vibration of the car compartment 11. The Fourier transform is a real-time Fourier transform processing method. For example, there is the short-time Fourier transform, etc.

[0040] The comparison and determination unit 23c determines whether there is a wheelchair user by comparing the frequency obtained by the signal processing unit 23b with specific vibration information.

[0041] The operation control unit 21 performs controls related to the operation of the car 8 based on the determination result of the information processing unit 23.

[0042] The operation control unit 21 provides two operating modes for the car 8: normal mode and wheelchair mode.

[0043] When the dedicated button 16 on the landing side or the dedicated button 18 on the car side is operated, the operation control unit 21 determines, based on the determination result of the information processing unit 23, whether there is a wheelchair-equipped user among at least one user associated with the call based on the operation. If a wheelchair-equipped user is determined to be present, wheelchair mode is selected as the operating mode. If no wheelchair-equipped user is determined to be present, normal mode is selected as the operating mode.

[0044] The operation control unit 21 controls the operation of the car 8, including at least one of the following: control of door opening non-interference time, control of opening and closing speed, and control of door opening time.

[0045] The door-opening non-interference time control refers to the time control for maintaining the car door 12 in the fully open state. The door-opening non-interference time in wheelchair mode is longer than the door-opening non-interference time in normal mode.

[0046] Opening and closing speed control refers to controlling the opening and closing speed of the car door 12. The opening and closing speed in wheelchair mode is lower than that in normal mode.

[0047] The door opening timing control controls the timing of the opening action of the car door 12. In normal mode, the opening action begins just before the car 8 stops at the floor, that is, before the car 8 comes to a complete stop. In wheelchair mode, the opening action begins after the car 8 stops at the floor and comes to a complete stop.

[0048] Furthermore, if the information processing unit 23 determines that there is a user deliberately shaking the car compartment 11 while the car 8 is in motion, the operation control unit 21 may also select wheelchair mode as the operating mode.

[0049] For example, if the dedicated button 16 on the landing side has been activated and it is determined that there is a wheelchair user among at least one user who has moved from the landing to the car compartment 11, the operation control unit 21 may extend the door opening non-interference time or make the door closing speed low.

[0050] Furthermore, even if the dedicated button 16 on the floor side has been activated but it is determined that there is no wheelchair user who has moved from the floor to the car compartment 11, the operation control unit 21 will not extend the door opening non-interference time, nor will it make the door closing speed low.

[0051] Furthermore, if, although the dedicated button 16 on the landing side is not operated, it is determined that there is a wheelchair user among at least one user who has moved from the landing to the car compartment 11, the operation control unit 21 may extend the door opening non-interference time or make the door closing speed low.

[0052] Furthermore, if it is determined that a wheelchair user has moved from the landing to the car compartment 11 and then selected the destination floor using the dedicated button 18 on the car side, the operation control unit 21 will begin the door opening operation after the car 8 has completely stopped at the destination floor. In this case, the operation control unit 21 can extend the door opening non-interference time at the destination floor or set the door closing speed to a low speed.

[0053] Furthermore, even if the dedicated button 18 on the car side has been activated but it is determined that there is no wheelchair user who has just moved from the landing to the car compartment 11, the operation control unit 21 will begin the door opening operation before the car 8 stops at the destination floor. In addition, in this case, the operation control unit 21 will not prolong the door opening non-interference time at the destination floor, nor will it reduce the opening and closing speed.

[0054] Furthermore, if, although only the regular button 17 on the car side has been operated, it is determined that at least one user who has just moved from the landing to the car compartment 11 is a wheelchair user, the operation control unit 21 may begin the opening operation after the car 8 has completely stopped at the destination floor. In this case, the operation control unit 21 may extend the door-opening non-interference time at the destination floor and may also make the door-closing speed low.

[0055] Figure 2 The block diagram shown is not limited to Figure 1 Machine-room-less elevators are also applicable to elevator systems with machine rooms, hydraulic elevators, and other types of elevator systems.

[0056] Figure 3This is a graph showing the characteristics of uniaxial vibrations in the vertical direction of the car compartment 11 when a regular user and a wheelchair-equipped user enter the car 8, respectively. The car compartment 11 is supported by the car frame 10. When a user moves from the landing to the car compartment 11 and from the car compartment 11 to the landing, vibrations occur in the car compartment 11 due to weight changes within the car compartment 11 and the accompanying impacts on the car compartment 11.

[0057] Furthermore, the impact exerted on the car compartment 11 during movement between the landing and the car compartment 11 differs between ordinary users and wheelchair-equipped users. This difference results in differences in the frequency characteristics of the vibrations generated in the car compartment 11.

[0058] exist Figure 3 In this context, frequency A is the frequency of vibration generated when a regular user moves from the landing to the car compartment 11. Furthermore, frequency B is the frequency of vibration generated when a wheelchair-equipped user moves from the landing to the car compartment 11, and it is lower than frequency A.

[0059] The information processing unit 23 processes the acceleration detection signal from the acceleration sensor 22 and converts the vibration generated in the car chamber 11 into a spectrum diagram in real time to determine whether there is frequency B.

[0060] Figure 3 The term "normal door closing" refers to the time when the door opens without interfering with the normal closing time. The information processing unit 23 performs a determination of whether there is a wheelchair user during the period from the start of door opening to the normal door closing time when the car stops at floor 8.

[0061] exist Figure 3 In the example, three regular users and one wheelchair-equivalent user were detected moving from the landing to the car compartment 11. Even when a regular user and a wheelchair-equivalent user moved into the car compartment 11 simultaneously, the presence of a wheelchair-equivalent user was determined by detection frequency B.

[0062] exist Figure 3 In the example, although a single axis in the vertical direction of the car is used, depending on the position of the acceleration sensor 22 installed in the car 8, more than one axis can also be used for determination.

[0063] Figure 4 It is shown Figure 2 A flowchart of the operation of the information processing unit 23. The information processing unit 23 repeatedly executes... Figure 4 The processing.

[0064] First, in step S101, the information processing unit 23 receives and acquires an acceleration detection signal from the acceleration sensor 22. Next, in step S102, the information processing unit 23 processes the acceleration detection signal to obtain the frequency of the vibration generated in the car chamber 11.

[0065] Then, in step S103, the information processing unit 23 compares the frequency of the vibration generated in the car compartment 11 with specific vibration information to determine whether there is a wheelchair user. Then, in step S104, the information processing unit 23 sends the determination result to the operation control unit 21.

[0066] In this elevator control system, the accelerometer 22 detects the acceleration of the car 11 and sends an acceleration detection signal. The information processing unit 23 receives and processes the acceleration detection signal, thereby determining whether a wheelchair user is present among at least one user moving between the landing and the car 11. Then, the operation control unit 21 performs control related to the operation of the car 8 based on the determination result of the information processing unit 23.

[0067] The information processing unit 23 stores specific vibration information. Furthermore, the information processing unit 23 determines whether there is a wheelchair user by comparing the value related to the vibration of the car 11 obtained by processing the acceleration detection signal with the specific vibration information.

[0068] Therefore, it can not only detect wheelchair users, but also more accurately detect wheelchair-equivalent users, including wheelchair users, thus improving convenience.

[0069] Methods that determine user categories by analyzing images of users obtained from cameras require advanced image recognition processing and complex judgment processing. Furthermore, it is difficult to determine the category of users located behind other users from camera observation. Additionally, due to the various shapes and sizes of wheelchairs, it is difficult to accurately detect wheelchair users. Moreover, it is also difficult to detect wheelchair-equipped users other than wheelchair users.

[0070] In this regard, the elevator control system of Embodiment 1 calculates the vibration frequency based on the acceleration detection signal, making the process simple. Furthermore, it allows for determination of the presence or absence of wheelchair-equipped users regardless of the number and location of users. Moreover, it enables more accurate detection of various types of wheelchair users and more accurate detection of wheelchair-equipped users other than wheelchair users.

[0071] Furthermore, when the dedicated button 16 on the landing side or the dedicated button 18 on the car side is operated, the operation control unit 21 determines, based on the determination result of the information processing unit 23, whether there is a wheelchair-equipped user among at least one user associated with the call based on that operation. If a wheelchair-equipped user is determined to be present, wheelchair mode is selected as the operating mode. If no wheelchair-equipped user is determined to be present, normal mode is selected as the operating mode.

[0072] Therefore, even if a regular user accidentally operates the dedicated button 16 on the landing side or the dedicated button 18 on the car side, wheelchair mode will not be selected as long as there is no wheelchair-equipped user among at least one user associated with calling the elevator. Thus, the reduction in the operating efficiency of the car 8 can be suppressed. Consequently, even in an elevator system containing multiple elevator units, the reduction in the overall operating efficiency of the system can be suppressed.

[0073] Furthermore, the controls related to the operation of the car 8 include at least one of the following: control of door opening non-interference time, control of opening and closing speed, and control of door opening timing. Therefore, it is possible to more reliably suppress the reduction in the operating efficiency of the car 8.

[0074] Furthermore, the information processing unit 23 calculates the frequency of vibration of the car compartment 11 as a value related to the vibration of the car compartment 11. Therefore, through simple processing, it is possible to make a more accurate determination related to whether or not a wheelchair-equipped user is present.

[0075] Furthermore, the specific vibration information is obtained in advance through machine learning. Therefore, it is possible to make more accurate determinations related to the presence or absence of wheelchair users, regardless of the differences in each elevator device.

[0076] Furthermore, the machine learning is supervised learning. In supervised learning, multiple users, including wheelchair-equipped users and ordinary users, are designated as samples. The acceleration detection signals obtained from the accelerometer 22 as each sample moves between the landing and the elevator car 11 are used as input data, and whether each sample is an ordinary user or a wheelchair-equipped user is used as output data.

[0077] Therefore, more appropriate specific vibration information can be obtained regardless of the differences in each elevator device, and more accurate determinations can be made regarding whether or not a wheelchair-equipped user is present.

[0078] Alternatively, the acceleration sensor 22 can be installed outside the car chamber 11, such as on the car frame 10, as long as it can detect the acceleration of the car chamber 11.

[0079] Alternatively, dedicated buttons can be located either at the landing or within the car compartment 11. Alternatively, dedicated buttons can be located at a distance from the landing (e.g., at the building entrance). Alternatively, dedicated buttons can be located on a portable terminal.

[0080] In addition, dedicated buttons can also be installed on touch panel-style floor control panels with equivalent functionality. Similarly, settings can be made using 3D (stereoscopic, airborne) buttons or sensor-based operation detection. The types of sensor detection can be set to include light, sound waves (including those inside and outside the audible area), voice, motion, etc.

[0081] In addition, the information processing unit 23 can be installed in a location other than the elevator car 8, or in a location far away from the elevator equipment.

[0082] Furthermore, the controls related to the operation of the car 8 may include controls other than those related to the movement of the car door 12. For example, the controls related to the operation of the car 8 may include the car 8's travel speed, the car 8's acceleration and deceleration, and the control of broadcast content to users.

[0083] Furthermore, methods for obtaining specific vibration information are not limited to machine learning; for example, it can also be derived through computer simulations. That is, specific vibration information can also be information obtained in advance through simulation.

[0084] Furthermore, specific vibration information can also be information using one or more pre-specified threshold values. For example, specific vibration information could also be a threshold value for the frequency of vibration in the car compartment 11, i.e., a frequency threshold. In this case, for example, if the frequency of vibration in the car compartment 11 is lower than the frequency threshold, it is determined that a wheelchair user is present.

[0085] Furthermore, specific vibration information can also be a threshold value for the acceleration generated in the car compartment 11, i.e., an acceleration threshold. In this case, for example, if the acceleration generated in the car compartment 11 is greater than the acceleration threshold, it is determined that a wheelchair user is present.

[0086] Furthermore, for specific vibration information, the acceleration threshold generated in the car compartment 11 can also be two. In this case, for example, if the acceleration generated in the car compartment 11 is between the two acceleration thresholds, it is determined that a wheelchair user is present.

[0087] Furthermore, the functions of the main control device 5, the door controller 13, and the information processing unit 23 in Embodiment 1 are implemented through processing circuits. Figure 5This is a structural diagram showing a first example of a processing circuit that implements the functions of the main control device 5, the door controller 13, and the information processing unit 23 in Embodiment 1. The processing circuit 100 in the first example is dedicated hardware.

[0088] Furthermore, the processing circuit 100 may be, for example, a single circuit, a composite circuit, a programmable processor, a parallel programmable processor, an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), or a combination thereof. Additionally, the functions of the main control device 5, the gate controller 13, and the information processing unit 23 may be implemented separately by the processing circuit 100, or the functions may be implemented centrally by the processing circuit 100.

[0089] also, Figure 6 This is a structural diagram of a second example of a processing circuit that implements the functions of the main control device 5, the gate controller 13, and the information processing unit 23 in Embodiment 1. The processing circuit 200 of the second example includes a processor 201 and a memory 202.

[0090] In the processing circuit 200, the functions of the main control device 5, the gate controller 13, and the information processing unit 23 are implemented through software, firmware, or a combination of software and firmware. The software and firmware are recorded as programs and stored in the memory 202. The processor 201 implements each function by reading and executing the programs stored in the memory 202.

[0091] The program stored in memory 202 can also be described as a program that causes the computer to execute the steps or methods described above. Here, memory 202 refers to, for example, non-volatile or volatile semiconductor memories such as RAM (Random Access Memory), ROM (Read-Only Memory), flash memory, EPROM (Erasable Programmable Read Only Memory), and EEPROM (Electrically Erasable Programmable Read Only Memory). Furthermore, storable media such as disks, floppy disks, optical disks, compact discs, mini-discs, and DVDs are also memory 202.

[0092] In addition, some of the functions of the above-mentioned parts can be implemented through dedicated hardware, and some can be implemented through software or firmware.

[0093] In this way, the processing circuit can implement the functions of the above-mentioned parts through hardware, software, firmware, or a combination thereof.

Various modifications and substitutions can be made to the embodiments described above without departing from the scope of the claims. Furthermore, there is no limitation on one or more such expressions, and various modifications and substitutions can be made to the embodiments described above without departing from the scope of the claims.

The information processing unit receives and processes the acceleration detection signal, thereby determining whether there is a wheelchair-equipped user among at least one user moving between the landing and the car interior. as well as The operation control unit performs controls related to the operation of the car based on the determination result of the information processing unit. The information processing unit stores specific vibration information related to the vibrations generated in the car cabin when the wheelchair-equipped user moves between the landing and the car cabin. The information processing unit compares the vibration-related value of the car compartment obtained by processing the acceleration detection signal with the specific vibration information to determine whether a wheelchair-equipped user exists. The information processing unit calculates the vibration frequency of the car compartment as a value related to the vibration of the car compartment.

2. The elevator control system according to claim 1, wherein, The operation control unit provides two operating modes for the car: a normal mode and a wheelchair mode. When the operation control unit is activated by a dedicated button used by wheelchair users, it determines, based on the determination result of the information processing unit, whether the wheelchair-equipped user is among at least one user associated with the elevator call based on the operation of the dedicated button. If it is determined that there is a user who is compatible with the wheelchair, the operation control unit selects the wheelchair mode as the operation mode. If it is determined that there is no wheelchair user, the operation control unit selects the normal mode as the operation mode.
