Description

  Embodiments described herein relate generally to an elevator system and a notification device.

  Normally, when an elevator car arrives at the landing on each floor, the door is automatically opened after a certain period of time. Further, when a person already in the car operates the door closing button, the door closing is forcibly started even within a predetermined time.

  Here, if the person who is going to get in is in a place away from the car that is open, there is a case where it is not possible to get on the door due to the passage of time or due to the operation of the person in the car. In order to solve such a problem, a method of extending the door opening time when a person on the hall is detected by a sensor has been considered.

(First embodiment)
FIG. 1 is a diagram illustrating a configuration of an elevator system according to the first embodiment. Here, a group management system having a plurality of cars will be described as an example, but a so-called “single elevator” in which one car operates each floor is also applicable.

  The group management control device 10 is provided with various functions for group management control of each car such as hall call assignment control. In the present embodiment, the group management control device 10 includes a notification unit 11, a landing person information acquisition unit 12, and a door opening extension unit 13 as functions used when each car is opened at the landing. It has been.

-About the alerting | reporting part 11 The alerting | reporting part 11 performs the process for alert | reporting the door opening time (time until a car door opens from the time of opening a car door) and the driving | running | working direction (up direction or down direction) which arrived at the landing. . The notification target is an elevator user, that is, a person in the hall and a person in the car. Specifically, the notification unit 11 outputs a notification command at a predetermined timing to the hall notification devices 21a, 21b,... And the car notification devices 31a, 31b,. Information (sound information) is used to notify the door opening time and driving direction (see FIGS. 4 to 11).

  In the group management system having a plurality of cars, a notification unit 11 may be provided for each car, or one notification unit 11 may be provided for each car. . When there is one notification unit 11 for each car, the door opening time and driving direction of the car with the door open are notified. In this case, if there are a plurality of cars whose doors are open at the same time, notification is made in accordance with a predetermined standard, such as matching the car with the shortest (or longest) door opening time.

-About the boarding person information acquisition part 12 The boarding person information acquisition part 12 is related to the person who exists in the boarding directly from the person information detection apparatus 2a, 2b ... installed near the boarding of each car, or via the person information collection part 101. Information (hereinafter referred to as landing person information) is acquired. The person information collecting unit 101 may be provided in the group management control device 10.

The boarding person information is any one of the following, or an arbitrary combination.
(A) Position of person
Position coordinates based on a specific point on the landing
(B) Person movement speed
Movement speed by walking and running. It may be calculated based on the position coordinates.
(C) Human movement trajectory
Information that links the position of the person moving on the hall in time series. What was calculated | required based on the said position coordinate may be used.
(D) Human behavior
Raise your hand, run, etc.
(E) Personal ID (identification)
This is an ID given to the elevator user in advance, and is used when adjusting the door opening time by identifying oneself.

  As the person information detection devices 2a, 2b,... For detecting these pieces of information, for example, cameras are used. In other words, a camera is installed at a place where the person information of the hall is obtained, and the person is detected by analyzing the image of the camera, and the position, moving speed, moving locus, behavior, and personal ID are detected in real time. .

  “Real time” as used herein includes the meaning of “immediately” or “immediately”. That is, even if a camera is used, there is time to analyze the image of the camera, so that the situation of passengers waiting for an elevator at the landing on each floor is detected immediately or almost immediately.

  In addition, about the method of specifying a person using a camera, a generally known method shall be used and a means in particular will not be ask | required. Further, a method of acquiring personal information using RFID (Radio Frequency Identification) or the like may be used. Furthermore, a method using a personal authentication device may be used.

-About the door opening extension part 13 The door opening extension part 13 determines whether the door opening extension is possible based on the door opening / closing information when the person on the landing is detected by the hall person information acquiring unit 12. If the door can be extended, the door opening time of the car will be extended more than usual.

  Normally, when the car arrives at the landing and opens the door, the door starts to be closed after a predetermined time has elapsed (for example, after 4 seconds). At this time, when the door opening button in the car is pressed, the count for the predetermined time is cleared and the door is opened again. Further, when the door closing button in the car is pressed while the door is open, the door closing is forcibly started even within the predetermined time.

  The door opening extension unit 13 determines that the door opening extension is possible when door closing information by pressing the door closing button is not input. If the door can be extended, the door extension portion 13 extends the door opening time of the car and reflects the extended time in the door opening time notified by the notification portion 11 at that time.

  The door opening / closing management unit 103 manages the door opening / closing state of each car. The door control unit 104 controls the opening / closing operation of the doors 4a, 4b,. The door opening / closing information input unit 102, the door opening / closing management unit 103, and the door control unit 104 may be provided separately from the group management control device 10 for each car, or the group management control device 10 may be provided.

  By these methods, when the car is open at the landing, it is possible for the person who has come to the landing to grasp instantly how long the car is open. A person in the car can also know the door opening time.

(B) Method of visually informing door opening time and driving direction FIG. 7 is a diagram showing a method of notifying the door opening time and driving direction using a lamp for each driving direction as a notification device. ) Shows a case where the car is driven downward, and FIG. 5B shows a case where the car is driven upward.

  The hall notification devices 21a, 21b... And the car notification devices 31a, 31b... Are provided with a plurality of lamps 51a, 51b arranged in a line as shown in FIGS. To do. The lamp 51a is an upward lamp having an upward arrow shape, and is lit when the car goes upward. The lamp 51b is a downward lamp having a downward arrow shape, and is lit when the car goes downward.

  Here, when the car goes upward, the door opening time and the upward driving operation are notified by reducing the number of lamps 51a to be lit as the door opening time of the car becomes shorter. Similarly, when the car goes downward, the door opening time and the downward driving are notified by decreasing the number of lamps 51b that are lit as the door opening time of the car becomes shorter.

  FIG. 8 is a diagram showing a method for notifying the door opening time and the driving direction by the blinking interval of the lamps according to the driving direction as a notification device.

  The hall notification devices 21a, 21b... And the car notification devices 31a, 31b... Are provided with at least two lamps 52a, 52b arranged in two upper and lower stages as shown in FIG. When the car goes upward, the lamp 52a is turned on, and the blinking interval of the lamp 52a is shortened (that is, blinked quickly) as the door opening time of the car becomes shorter. Similarly, when the car goes downward, the lamp 52b is turned on, and the blinking interval of the lamp 52b is shortened (that is, blinked quickly) as the door opening time of the car becomes shorter.

  FIG. 9 is a diagram showing a method for notifying the door opening time and the driving direction using a display device as a notification device.

  The hall notification devices 21a, 21b,... And the car notification devices 31a, 31b,... Are provided with a display 53 made of, for example, an LCD (Liquid Crystal Display) as shown in FIG. The display 53 displays the current door opening time in real time, and further displays a symbol indicating the driving direction of the car.

  By these methods, when the car is open at the landing, it is possible to instantly know how long the car that has arrived at the landing has been opened and in which direction it will go. . A person in the car can also know the door opening time and driving direction.

(C) Method for Aurally Notifying Door Opening Time FIG. 10 is a diagram illustrating a method for notifying the door opening time using a speaker as a notification device.

  The hall notification devices 21a, 21b,... And the car notification devices 31a, 31b,... Are provided with a speaker 61 that is a sound generating device as shown in FIG. The interval of the sound generated from the speaker 61 is gradually advanced according to the door opening time of the car.

(D) Method of Auditively Notifying Door Opening Time and Driving Direction FIG. 11 is a diagram showing a method of notifying the door opening time and driving direction using a speaker as a notification device.

  The hall notification devices 21a, 21b,... And the car notification devices 31a, 31b,... Are provided with a speaker 61 that is a sound generating device, as shown in FIG. The interval of the sound generated from the speaker 61 is gradually advanced according to the door opening time of the car. Furthermore, the pitch of the sound is changed in accordance with the driving direction, such as “low sound → high sound” when the driving direction of the car is upward, and “high sound → low sound” when the driving direction is downward.

  By these methods, even when the door cannot be seen directly at the landing, the door opening time and the driving direction can be instantly grasped by sound information. Moreover, even visually impaired people can be recognized and can ride safely. The person in the car can also instantly grasp the door opening time and driving direction from the sound information.

  Note that the visual notification method and the auditory method described above may be combined.

  Also, for example, the normal door opening time is notified by lighting the lamp, the door opening extended time is notified by sound from the speaker, or the normal door opening time is notified by lamp lighting, and the door opening extended time is indicated by the lamp. The notification method may be changed between the normal door opening time and the extended door opening time, such as notification by blinking.

Next, the door opening extension part 13 is demonstrated with reference to a flowchart.
FIG. 12 is a flowchart showing the processing of the door opening extension 13 of the elevator system in the first embodiment. Note that the processing of this flowchart is repeated, for example, every 0.1 [s].

  In the following, a case will be described in which the car 30a shown in FIG. 3 is taken as an example and this car 30a arrives at a landing on an arbitrary floor and opens.

  When the car 30a arrives at the landing, the door opening extension unit 13 determines whether the car 30a is in the door open state through the door opening / closing management unit 103 (step S11). If the car 30a is in the door open state (Yes in step S11), the door opening extension unit 13 determines whether or not a person on the landing is detected based on the landing person information obtained by the landing person information acquisition unit 12. Is determined (step S12).

  At that time, it may be determined whether or not a person with a willingness to board is detected. As a determination method, for example, if the person information detection device 2a is a camera, based on the image of the camera, the person is in a certain area near the door, the moving speed is a certain value or more, or the movement locus is in the door direction. This is done by analyzing whether it is heading. Further, it may be determined whether the user is on the floor from the personal ID of the person.

  When a person on the landing is detected (Yes in step S12), the door opening extension unit 13 determines whether the door opening extension can be extended through the door opening / closing management unit 103 (step S13). When door opening extension is not possible (when door opening extension is not permitted), for example, when the door opening time has passed a certain period of time, which is a door closing condition, or when the door closing information input means 102 instructs the door closing. For example.

  Alternatively, the time required for the person to get on the car 30a when the door is open may be estimated and used for the determination of the door opening extension. That is, the time required for boarding is estimated from the current position based on attribute information such as the position and moving speed of the person, wheelchair users, and elderly people, and is extended when the estimation result is X seconds or more (for example, X = 10). It is determined that it is impossible.

  When it is determined that the door opening extension is possible (Yes in step S13), the door opening extension unit 13 instructs the door opening / closing management unit 103 to open the door. Thereby, the door opening time of the car 30a is extended more than usual through the door opening / closing management unit 103 and the door control unit 104 (step S14).

  The extension time may be fixed (for example, 3 seconds), or the time required for the person to get on may be estimated, and the door opening time may be extended in consideration of the time.

  However, if a person comes to the landing while the car 30a is open, it may be difficult to leave because the door is extended each time the person is detected. Therefore, when the person in the car 30a performs a specific operation such as pressing the door closing button twice continuously during the door opening extension in step S14, the door opening extension is prohibited. May be.

  Further, the extension determination result is sent from the door opening extension unit 13 to the notification unit 11. In this case, when the car 30a is opened, the notifying unit 11 notifies the normal door opening time through the hall notifying device 21a and the car notifying device 31a corresponding to the car 30a regardless of the presence or absence of a person at the hall. doing. Here, in Step S13, when receiving the determination result that the door opening extension is possible from the door opening extension unit 13, the notification unit 11 includes the normal door opening time including the extension time for the hall corresponding to the car 30a. The notification is made through the notification device 21a and the car notification device 31a.

  As described above, when the door opening time is notified, it is possible to notify including the driving direction. The specific notification method is as described with reference to FIGS. 4 to 11, and visual or audible notification is performed using a lamp (indicator), a display, a speaker, or the like.

  As described above, according to the first embodiment, when a person who has come to the landing is detected when the car is opened, the door opening time is extended, and the current door opening including the extension is included. The time will be announced in the platform and in the car. Therefore, the person who has come to the landing can know when the door is closed, and can ride in peace if there is a margin in the door opening time without performing a dangerous act such as rushing and running. On the other hand, people in the car can know when the door is closed, so they can wait with peace of mind even if the door is extended.

  Furthermore, by notifying the driving direction along with the door opening time, it is possible for both the person who has come to the landing and the person in the car to ride safely without making a mistake in the up and down directions.

(Second Embodiment)
Next, a second embodiment will be described.

  In the first embodiment, the door is extended when a person on the landing is detected regardless of the presence or absence of a person in the car. However, for example, when a large number of people are in the car, there is a possibility that the passenger cannot ride even if the door is extended. Therefore, in the second embodiment, the door opening extension is performed in consideration of the state in the car.

  FIG. 13 is a diagram illustrating a configuration of an elevator system according to the second embodiment. In addition, the same code | symbol is attached | subjected to the same part as the structure of FIG. 1 in the said 1st Embodiment, and the detailed description shall be abbreviate | omitted.

  In the second embodiment, the group management control device 10 includes an in-car person information acquisition unit 14. The in-car personal information acquisition unit 14 acquires information about a person in the car (hereinafter, in-car personal information) directly from the personal information detection devices 2a, 2b,... Or from the personal information collection unit 101 for each car. .

The person information in the car is any one of the following, or any combination.
・ Possible number of passengers How many people can ride in the open car? Calculate from the current number of passengers in the car and the number of people that can be loaded (rated people).
・ Ride space
How much space is available in the car when the door is open?

  As the person information detecting devices 2a, 2b,... For detecting such information, for example, cameras are used as in the first embodiment. At this time, the camera may be installed separately in the landing and in the car, or in any place such as in the landing, in the car, or near the door, and obtain personal information on both the landing and the car. You may be able to do it. Further, a load sensor (not shown) installed in the car may be used.

  In such a configuration, the door opening extension unit 13 performs the door opening extension determination in consideration of the in-car person information acquired by the in-car person information acquisition unit 14. Specifically, in step S13 of FIG. 12 described above, it is determined whether or not the door opening extension is possible based on the number of passengers or the boarding space in the car. For example, when the number of passengers that can be boarded is X or less (such as X = 2), it is determined that the door opening extension is impossible. In addition, when the number of people that can be boarded is X% or less of the loading capacity (X = 20, etc.), the space that can be boarded is X people or less (X = 2), and the space that can be boarded is X% or less of the car interior area ( When X = 20), it may be determined that the door opening extension is impossible.

  Further, the current boarding rate may be obtained based on the person information in the car, and the door opening extension time may be determined according to the boarding rate. The processing at this time is shown in FIG.

  FIG. 14 is a flowchart showing the process of the door opening extension 13 of the elevator system in the second embodiment. Note that the processing of this flowchart is repeated, for example, every 0.1 [s].

  In the following, a case will be described in which the car 30a shown in FIG. 3 is taken as an example and this car 30a arrives at a landing on an arbitrary floor and opens. Steps S21 to S22 are the same as steps S11 to S12 in FIG.

  That is, when the car 30a arrives at the landing, the door opening extension unit 13 determines whether the car 30a is in the door open state through the door opening / closing management unit 103 (step S21). If the car 30a is in the door open state (Yes in step S21), the door open extension unit 13 determines whether or not a person on the landing is detected based on the landing person information obtained by the landing person information acquisition unit 12. Is determined (step S22).

  Here, when the person on the landing is detected (Yes in step S22), the door opening extension unit 13 calculates the current boarding rate based on the in-car person information obtained by the in-car person information acquisition unit 14. (Step S23). The boarding rate can be calculated from the current number of passengers and the number of people that can be loaded (rated people). In addition, this boarding rate may be included as one of the person information in the car, similarly to the above-mentioned number of people who can board and the space where people can board.

  If the current boarding rate is equal to or greater than a preset value, the door opening extension unit 13 determines that door opening extension is not possible. On the other hand, when the current boarding rate is less than a preset value, the door opening extension unit 13 determines that the door opening extension is possible. When it is determined that the door opening can be extended (Yes in step S24), the door opening extension unit 13 determines the door opening extension time according to the current boarding rate, and the door opening / closing management unit 103 is provided for the time. Instruct the door extension. Thereby, the door opening time of the car 30a is extended more than usual through the door opening / closing management unit 103 and the door control unit 104 (step S25). In this case, the lower the current boarding rate (when there is a vacant space), the longer the door opening time is. Conversely, the higher the current occupancy rate (when there is no room in the vacant space), the shorter the door opening time.

  As described above, according to the second embodiment, by extending the door opening in consideration of the state in the car, for example, when the door is almost full, the door is inadvertently extended and the person or the passenger on the landing It is possible to prevent annoying the person in the car. In addition, by determining the time for extending the door opening according to the current boarding rate, when the boarding rate is high, the door opening time can be shortened and the departure can be made as soon as possible. On the other hand, when the boarding rate is low, it is possible to start with a large number of people on the hall by extending the door opening extension time.

(Third embodiment)
Next, a third embodiment will be described.

  In the first embodiment, since the person at the landing is detected by a camera or the like, there is a possibility that the person who has just passed through the landing is erroneously detected and the door is extended. Therefore, in the third embodiment, the door opening extension is performed only when a specific action such as raising a hand is detected.

  FIG. 15 is a diagram illustrating a configuration of an elevator system according to the third embodiment. In addition, the same code | symbol is attached | subjected to the same part as the structure of FIG. 1 in the said 1st Embodiment, and the detailed description shall be abbreviate | omitted.

  In the third embodiment, the group management control device 10 includes an instruction transmission unit 15. The instruction transmission unit 15 instructs the person to take a specific action when it is detected by the hall person information acquisition 12 that there is a person at the hall.

The contents of the instruction include the following, for example.
-Raise your hand when riding.
・ Please turn your face to the sensor when boarding.
・ When getting on, approach the door side wall.
As a method of instruction transmission, for example, the above contents are guided by voice from a speaker using the hall notification devices 21a, 21b... Installed at the hall, or the above contents are displayed on a monitor.

  Here, the door opening extension unit 13 performs door opening extension only when the person who takes the specific action is detected at the landing by the landing person information acquisition 12. In addition, it is detected by the image analysis of a camera, for example that the person in a hall took the said specific action. The process of the door opening extension part 13 is shown in FIG.

  FIG. 16 is a flowchart showing the processing of the door opening extension 13 of the elevator system in the third embodiment. Note that the processing of this flowchart is repeated, for example, every 0.1 [s].

  In the following, a case will be described in which the car 30a shown in FIG. 3 is taken as an example and this car 30a arrives at a landing on an arbitrary floor and opens. Steps S31 to S32 are the same as steps S11 to S12 in FIG.

  That is, when the car 30a arrives at the landing, the door opening extension unit 13 determines whether or not the car 30a is in the door open state through the door opening / closing management unit 103 (step S31). If the car 30a is in the door open state (Yes in step S31), the door opening extension unit 13 determines whether or not a person on the landing is detected based on the landing person information obtained by the landing person information acquisition unit 12. Is determined (step S32).

  Here, when a person on the landing is detected (Yes in step S32), the door opening extension unit 13 instructs the person to take a specific action through the instruction transmission unit 15 (step S33). Specifically, "Please raise your hand when riding," "Please face your sensor when riding," "Please approach the door side wall when riding" Or it tells the person concerned by display.

  In response to this instruction, when the hall person information acquisition unit 12 detects that the person has taken a specific action (Yes in step S34), the door opening extension unit 13 passes through the door opening / closing management unit 103. It is determined whether or not the door can be extended (step S35).

  As described in the first embodiment, when the door opening extension is not possible (when door opening extension is not permitted), for example, when the door opening time has passed a certain time that is a door closing condition, This is the case when a door closing instruction is received from the door closing information input means 102. Alternatively, the time required for the person to get on the car 30a when the door is open may be estimated and used for the determination of the door opening extension. Further, as in the second embodiment, the door opening extension determination may be performed in consideration of the person information in the car.

  When it is determined that the door opening extension is possible (Yes in step S35), the door opening extension unit 13 instructs the door opening / closing management unit 103 to open the door. Thereby, the door opening time of the car 30a is extended more than usual through the door opening / closing management unit 103 and the door control unit 104 (step S14).

  As described above, according to the third embodiment, when the person at the hall takes a specific action according to the instruction, the door opening is extended so that the person who has just passed through the hall is detected and the door is opened carelessly. Prolonging can be prevented.

  In the example of FIG. 16, the person on the landing is instructed to take a specific action, but if a person who has taken a specific action is detected without giving such an instruction, the door Open extension may be performed. In this case, for example, if you put something like a guide version at the entrance of the boarding area and write a memo such as “Please raise your hand when boarding”, you do not have to give instructions. FIG. 17 shows a process when a specific action instruction is not issued.

  FIG. 17 is a flowchart showing a process in the case where a specific action instruction of the elevator door opening extension 13 in the third embodiment is not issued.

  That is, when the car 30a arrives at the landing, the door opening extension unit 13 determines whether the car 30a is in the door open state through the door opening / closing management unit 103 (step S41). If the car 30a is in the door open state (Yes in step S41), the door open extension unit 13 is a person who took a specific action at the hall based on the hall person information obtained by the hall person information acquisition unit 12 Whether or not is detected is determined (step S42).

  Here, when the corresponding person is detected (Yes in step S42), the door opening extension unit 13 determines whether the door opening extension can be extended through the door opening / closing management unit 103 (step S43). If it is determined that the door opening extension is possible (Yes in step S35), the door opening extension unit 13 instructs the door opening / closing management unit 103 to open the door. As a result, the door opening time of the car 30a is extended more than usual through the door opening / closing management unit 103 and the door control unit 104 (step S44).

  In this way, even if a specific action is not instructed, the person who has taken such action is detected and the door is extended to detect the person who has just passed through the landing as above. It is possible to prevent the door from being extended.

  According to at least one embodiment described above, it is possible to provide an elevator system and a notification device that enable a person who has come to the landing to know the door open state of the car and to get on safely.

  In addition, although some embodiment of this invention was described, these embodiment is shown as an example and is not intending limiting the range of invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention.
