Modifications that can be easily conceived by those skilled in the art are naturally included in the scope of disclosure. In order to clarify the explanation, in the drawings, the size, shape, etc. of each part may be changed with respect to the actual embodiment and represented schematically. In a plurality of drawings, the corresponding elements may be given the same reference numerals and detailed description may be omitted.

(First Embodiment)
FIG. 1 is a diagram showing a configuration of an elevator system according to the first embodiment. Although the description will be given here by taking one car as an example, the same configuration is used for a plurality of cars.

A camera 12 is installed above the doorway of the car 11. Specifically, the camera 12 is installed in the curtain plate 11a covering the upper part of the entrance / exit of the car 11 with the lens portion tilted directly downward, or on the landing 15 side or the inside of the car 11 by a predetermined angle. ..

The camera 12 is a small surveillance camera such as an in-vehicle camera, has a wide-angle lens or a fisheye lens, and can continuously capture images of several frames (for example, 30 frames / second) per second. The camera 12 is activated when the car 11 arrives at the landing 15 on each floor, and takes a picture including the vicinity of the car door 13 (the entrance / exit of the car 11).

The shooting range at this time is adjusted to L1 + L2 (L1 >> L2). L1 is a shooting range on the landing side, and has a predetermined distance from the car door 13 toward the landing 15. L2 is an imaging range on the car side, and has a predetermined distance from the car door 13 toward the back of the car. It should be noted that L1 and L2 are ranges in the depth direction, and the range in the width direction (direction orthogonal to the depth direction) is at least larger than the width of the car 11.

At the landing 15 on each floor, a landing door 14 is installed at the arrival port of the car 11 so as to be openable and closable. The landing door 14 engages with the car door 13 when the car 11 arrives to open and close. The power source (door motor) is on the car 11 side, and the landing door 14 only opens and closes following the car door 13. In the following description, it is assumed that the landing door 14 is also open when the car door 13 is open, and the landing door 14 is also closed when the car door 13 is closed.

Each image (video) continuously captured by the camera 12 is analyzed and processed in real time by the image recording device 20. Although the image recording device 20 is taken out from the car 11 for convenience in FIG. 1, the image recording device 20 is actually housed in the curtain plate 11a together with the camera 12.

The image recording device 20 is used as a device for detecting the user situation on each floor using the captured image of the camera 12 and recording the detection result. Specifically, the "user status of each floor" is the number of passengers getting on and off the car 11 on each floor, and the number of passengers getting on and off the car 11 including the number of passengers getting off the car 11. The more people get on and off the floor, the more crowded it is.

The image recording device 20 includes a storage unit 21 and a user detection unit 22. The storage unit 21 has a buffer area for sequentially storing images taken by the camera 12 and temporarily storing data necessary for processing by the user detection unit 22. It should be noted that the storage unit 21 may store an image that has been subjected to processing such as distortion correction, enlargement / reduction, and partial cropping as preprocessing for the captured image. The storage unit 21 is provided with a user status table 21a for managing the user status (number of users) detected by the user detection unit 22 for each floor.

The user detection unit 22 has a predetermined image processing function, and detects a user who gets on and off the car 11 from the shooting range (L1 + L2) of the camera 12 when the car 11 stops on an arbitrary floor. do. The user detection unit 22 counts the number of users detected from the captured image of the camera 12 in a predetermined time unit, and sets the floor information indicating the floor as the user status of the floor in which the car 11 is stopped. It is associated and recorded in the user status table 21a.

FIG. 2 shows an example of the user status table 21a. In this example, the number of users is recorded in units of 1 hour, but the number of users may be recorded in units of 30 minutes, for example. In addition, the number of users may be recorded separately for the morning and afternoon hours. Alternatively, a preset congestion time zone (for example, 9:00 to 10:00, 12:00 to 13:00, 17:00 to 18:00) and a quiet time zone (for example, 9:00 to 10:00, The number of users may be recorded separately (time zones other than 12:00 to 13:00 and 17:00 to 18:00). The elevator control device 30 may have a part or all of the functions of the image recording device 20.

The elevator control device 30 controls the operation of various devices (destination floor buttons, lighting, etc.) installed in the car 11. The elevator control device 30 includes a door open / close control unit 31. The door opening / closing control unit 31 controls the opening / closing of the door of the car door 13 when the car 11 arrives at the landing 15. In the present embodiment, the door opening / closing control unit 31 sets the door opening waiting time of each floor in the door opening control table 31a in hours based on the user status (number of users) of each floor obtained from the image recording device 20. Has the function of

FIG. 3 shows an example of the door open control table 31a.
In the door opening control table 31a, the door opening waiting time of each floor is set for each predetermined time unit. In the figure, Ta is the reference time, α is the extension time with respect to the reference time, and β is the shortened time with respect to the reference time. The reference time Ta is determined by the size of the car 11 and the like. The times of α and β may be the same or different values. The time unit is the same as that of the user status table 21a shown in FIG. 2, for example, every hour.

The door opening / closing control unit 31 refers to the user status table 21a to make the door opening waiting time on the floor with a large number of users longer than Ta by α (Ta + α), and waits for the door opening on the floor with a small number of users. Make the time shorter than Ta by β (Ta-β). The user status table 21a and the door opening control table 31a may be created as one table and managed by the image recording device 20 side or the elevator control device 30 side.

FIG. 4 is a diagram showing a configuration of a portion around the doorway in the car 11.
A car door 13 is provided at the entrance and exit of the car 11 so as to be openable and closable. In the example of FIG. 4, a two-door double door type car door 13 is shown, and the two door panels 13a and 13b constituting the car door 13 open and close in opposite directions along the frontage direction (horizontal direction). .. The "frontage" is the same as the entrance / exit of the car 11.

Front pillars 41a and 41b are provided on both sides of the doorway of the car 11, and surround the doorway of the car 11 together with the curtain plate 11a. The "front pillar" is also referred to as an entrance / exit pillar or an entrance / exit frame, and a door pocket for accommodating the car door 13 is generally provided on the back side. In the example of FIG. 4, when the car door 13 is opened, one door panel 13a is housed in a door bag 42a provided on the back side of the front pillar 41a, and the other door panel 13b is provided on the back side of the front pillar 41b. It is stored in the door bag 42b.

A display 43, an operation panel 45 on which a destination floor button 44 and the like are arranged, and a speaker 46 are installed on one or both of the front pillars 41a and 41b. In the example of FIG. 4, the speaker 46 is installed on the front pillar 41a, the display 43 and the operation panel 45 are installed on the front pillar 41b. Here, a camera 12 having a wide-angle lens is installed in the central portion of the curtain plate 11a above the entrance / exit of the car 11.

FIG. 5 is a diagram showing an example of a captured image of the camera 12. The upper side is the landing 15, and the lower side is the inside of the car 11.

The car door 13 has two door panels 13a and 13b that move in opposite directions on the car sill 47. The same applies to the landing door 14, which has two door panels 14a and 14b that move in opposite directions on the landing sill 18. The door panels 14a and 14b of the landing door 14 move in the door opening / closing direction together with the door panels 13a and 13b of the car door 13.

The camera 12 is installed above the doorway of the car 11. Therefore, when the car 11 opens at the landing 15, as shown in FIG. 1, a predetermined range (L1) on the landing side and a predetermined range (L2) in the car are photographed. The image recording device 20 is installed at the upper part of the doorway of the car 11 together with the camera 12, and analyzes and processes the image information obtained from the camera 12 to detect the user getting on and off the car 11. As the image analysis method, a generally known method is used, and detailed description thereof will be omitted here.

In the present embodiment, the camera 12 and the image recording device 20 are installed in the car 11, but as shown in FIG. 6, for example, the camera 51 and the image recording device 52 may be installed on the ceiling of the landing 15 on each floor. good. The camera 51 photographs the vicinity of the entrance / exit of the car 11 and sends the captured image to the image recording device 52. The image recording device 52 has the same function as the image recording device 20, and when the car 11 stops at the landing 15 on each floor and opens the door, the image taken by the camera 12 is used to get on and off the car 11. Detects and records the number of users.

Further, in the case of an elevator group management system having a plurality of car cars, as shown in FIG. 7, cameras 51a, 51b, 51c ... And image recording devices 52a, 52b, 52c ... Is installed to detect and record the number of users for each car.

Next, the operation of this system will be described.
FIG. 8 is a flowchart showing the operation of the elevator system according to the first embodiment. The process shown in this flowchart is executed by the image recording device 20 and the elevator control device 30.

When the car 11 stops at an arbitrary floor and opens the door, the user detection unit 22 provided in the image recording device 20 acquires an image of the vicinity of the entrance / exit of the car 11 from the camera 12 and obtains an image of the vicinity of the entrance / exit of the car 11 from the image. Detects users getting on and off the car 11 on the floor. The number of users detected by the user detection unit 22 is counted for each predetermined time unit, and is recorded in the user status table 21a provided in the storage unit 21 in association with the floor information (step). S11).

When the car 11 is stopped on each floor, the same process as described above is repeated, and the number of users getting on and off the car 11 on each floor is recorded in the user status table 21a as the user status. In the example of FIG. 2, the result of recording the number of users in an hourly unit is shown. There are some floors where the car 11 does not stop depending on the time of day only by driving for one day, and the number of users may increase or decrease only for that day for some reason. Therefore, it is preferable to obtain the number of users who get on and off the car 11 on each floor for a certain period of time (for example, one week or one month), and record the average number of users per day in the user status table 21a. After a certain period of time has elapsed, the user status of each floor is detected each time while the car 11 is in operation, and the user status table 21a is updated.

After a lapse of a certain period (Yes in step S12), the door opening / closing control unit 31 provided in the elevator control device 30 controls the door opening standby time of each floor as follows using the user status table 21a. When the user status table 21a is in the initial state, for example, immediately after delivery of the elevator, the door opening waiting time on each floor is set to the reference time Ta.

The door open / close control unit 31 checks the number of users on each floor recorded in the user status table 21a, and searches for a floor in which the number of users per unit time is larger or smaller than the standard (step S13). The standard for the number of users is determined by the average number of people getting on and off per unit time, and has a certain range. Here, for example, 45 to 55 people per unit time is used as a standard.

If there is a floor with a larger number of users than the reference time (Yes in step S13), the door opening / closing control unit 31 makes the door opening waiting time in the corresponding time zone longer than the reference time Ta (step S14). .. Specifically, the door open / close control unit 31 sets the door open standby time in the corresponding time zone to Ta + α and records it in the door open control table 31a. On the other hand, if there is a floor where the number of users is less than the standard (Yes in step S15), the door opening / closing control unit 31 shortens the door opening waiting time in the corresponding time zone to be shorter than the reference time Ta (step). S16). Specifically, the door opening / closing control unit 31 sets the door opening waiting time in the corresponding time zone to Ta-β and records it in the door opening control table 31a.

If the number of users per unit time is within the standard range (No in step S15), the door opening / closing control unit 31 sets the door opening waiting time of the floor to the reference time Ta and the door opening control table. Record in 31a (step S17). Then, it is confirmed whether or not the door opening waiting time is set for all the floors in any of the processes of steps S14, S16, and S17 (step S18). If there is a floor for which the door opening waiting time setting has not been completed (No in step S18), the process returns to the process of step S13 for the unset floor. If the door opening waiting time is set for all floors (Yes in step S18), the process ends. For all floors subject to door opening / closing control, the door opening / closing control unit 31 sets the door opening standby time by comparing the number of users obtained from the image recording device 20 with a reference for each hour. As a result, the door open control table 31a as shown in FIG. 3 is created.

After that, when the car 11 is stopped on an arbitrary floor and the door is opened, the door open / close control unit 31 adjusts the door open waiting time with reference to the door open control table 31a. Specifically, the door opening / closing control unit 31 reads out the door opening waiting time corresponding to the current time zone of the floor where the car 11 has stopped from the door opening control table 31a, and during the door opening waiting time, the door opening / closing control unit 31 of the car 11 Keep the door open.

Specifically, for example, it is assumed that the car 11 stops on the first floor and opens. As shown in FIG. 3, in the time zone of "6:00 to 7:00", the door opening waiting time is the reference time Ta. On the other hand, even on the same first floor, if the number of users is large during the time zone of "7:00 to 8:00" or "8:00 to 9:00", the door opening waiting time is Ta + α. Is extended by α minutes with respect to the reference time Ta. Therefore, the user can get on and off the car 11 without rushing.

On the other hand, in the case of the second floor, the number of users is small during the time zones of "6:00 to 7:00" and "7:00 to 8:00". The door opening waiting time at this time becomes Ta-β, which is shortened by the time β with respect to the reference time Ta. Therefore, when the number of users is small, it is possible to keep the door open state unnecessarily and prevent the operation efficiency from being lowered.

As described above, according to the first embodiment, the door opening waiting time can be set according to the user situation on each floor. Therefore, on a floor with a small number of users, it is possible to prevent a decrease in operation efficiency by shortening the door opening waiting time. On the other hand, on a floor with a large number of users, it is possible to prevent the door from closing while the user gets on and off by lengthening the door opening waiting time. Furthermore, by monitoring the user status of each floor in a predetermined time unit and setting the door opening waiting time for each time unit, it is possible to flexibly respond to the user situation that changes depending on the time zone. ..

In the first embodiment, the door opening control table 31a in which the door opening waiting time is set for each floor is prepared in advance. For example, when the vehicle is stopped on any floor of the car 11. , The user status table 21a may be referred to to obtain the door opening waiting time of the floor corresponding to the time zone at that time.

By the way, there is known a system that detects a user at a landing using a camera and reflects the detection result in a door opening / closing control in real time. However, in this type of system, the user situation on each floor is not analyzed to determine the door opening waiting time, but the user at that time is captured by the camera and reflected in the door opening waiting time. I'm just there. In this case, if there is a user in the blind spot of the camera, it cannot be reflected in the door opening waiting time.

On the other hand, in this system, the number of users including the number of people getting on the car (number of people getting on) and the number of people getting off the car (number of people getting off) on each floor is recorded as the user status, and the result is recorded as the user status. It is reflected in the open waiting time. Therefore, the user situation on each floor can be correctly reflected in the door opening waiting time. In other words, for example, when a new tenant enters a floor in a building and the number of users on that floor suddenly increases, or when a tenant on a certain floor moves and the number of users on that floor suddenly decreases. There is an advantage that the waiting time for opening the door can be optimized flexibly in response to changes in the user situation on each floor.

(Modification example)
In the first embodiment described above, the door opening waiting time is changed depending on whether the number of users on each floor is larger or smaller than the standard, but the door opening waiting time is set according to the number of users on each floor. It is good as a configuration to be changed.

Specifically, if the number of users is larger than the standard, the larger the number of users, the longer the door opening waiting time, such as Ta + α1, Ta + α2, Ta + α3, etc., depending on the number of users at that time (Ta + α1, Ta + α2, Ta + α3, etc.) α1 <α2 <α3). This makes it possible to prevent the door from closing while the users are getting on and off, even on a floor with a very large number of users.

On the contrary, if the number of users is smaller than the standard, the smaller the number of users, the longer the door opening waiting time, such as Ta-β1, Ta-β2, Ta-β3, etc., depending on the number of users at that time. Is shortened (β1 <β2 <β3). As a result, when there is a floor with a very small number of users, it is possible to close the door as soon as possible to prevent a decrease in operation efficiency.

(Second embodiment)
Next, the second embodiment will be described.
The second embodiment assumes a group management system for elevators having a plurality of cars. Normally, in an elevator group management system, when a landing call occurs on any floor, the fastest arriving car is selected as the assigned car based on the driving information (car position, driving direction, etc.) of each car. .. At that time, the second embodiment is characterized in that the allocation car is selected in consideration of the door opening waiting time of each floor.

FIG. 9 is a diagram showing a configuration of an elevator group management system according to a second embodiment. Although the configuration in which three cars are managed as a group is taken as an example here, the number of cars is not limited to three, and two or more cars may be used.

It exists as a group management control device 61 and a main controller, and comprehensively controls the operation of a plurality of cars 64a, 64b, 64c. The elevator control devices 62a, 62b, 62c control the operation of the car 64a, 64b, 64c under the control of the group management control device 61. Specifically, the elevator control device 62a controls a motor (winding machine) (not shown) for raising and lowering the car 32a of Unit A, controls opening and closing of doors, and the like. The same applies to the elevator control device 62b and the elevator control device 62c. The group management control device 61, the elevator control devices 62a, 62b, 62c ... Are realized by a computer each equipped with a CPU, a ROM, a RAM, or the like.

Here, the cameras 65a, 65b, 65c and the image recording devices 66a, 66b, 66c are installed in the car 64a, 64b, 64c, respectively. The cameras 65a, 65b, 65c and the image recording devices 66a, 66b, 66c correspond to the camera 12 and the image recording device 20 shown in FIG.

That is, the camera 65a installed in the car 64a of the No. A takes a picture of the vicinity of the entrance / exit of the car 64a and sends the taken image to the image recording device 66a. Similar to the image recording device 20, the image recording device 66a includes a storage unit 21 and a user detection unit 22, and obtains and records the number of users for each time unit on each floor from the captured image of the camera 65a. The same applies to the camera 65b and the image recording device 66b installed in the car 64b of Unit B, and the camera 65c and the image recording device 66c installed in the car 64c of Unit C.

The elevator control device 62a sets the door opening standby time when the car 64a of Unit A stops on each floor based on the number of users for each time unit recorded in the image recording device 66a. The elevator control device 62b sets the door opening standby time when the car 64b of Unit B stops on each floor based on the number of users for each time unit recorded in the image recording device 66b. The elevator control device 62c sets the door opening standby time when the car 64c of Unit C stops on each floor based on the number of users for each time unit recorded in the image recording device 66c.

The landing call buttons 68a, 68b, 68c ... Are installed at the landings 67a, 67b, 67c ... On each floor. For example, when the landing call is registered by operating the landing call button 68a, the group management control device 61 assigns the landing call to any of the car 64a, 64b, 64c. At that time, the group management control device 61 selects the allocation car in consideration of the door opening waiting time of each floor set in each unit, and directs the allocation car to the floor where the landing call is generated.

FIG. 10 is a flowchart showing the operation of the elevator group management system in the second embodiment. The process shown in this flowchart is executed by the group management control device 61. Now, it is assumed that the elevator control devices 62a, 62b, 62c of each unit are individually set to the door opening waiting time of each floor in a predetermined time unit by the method described in the first embodiment.

When a landing call occurs on any floor (Yes in step S21), the group management control device 61 acquires operation information of each unit via the elevator control devices 62a, 62b, 62c (step S22). The driving information includes the current car position, the driving direction, unanswered call information, and the like. "Unanswered calls" include landing calls registered on other floors and car calls (destination calls) registered in the car. Normally, the allocation car is selected based on this operation information, but in the present embodiment, the door opening waiting time of each floor is taken into consideration in the selection of this allocation car.

That is, the group management control device 61 acquires the door opening waiting time of each floor in the current time zone from the elevator control devices 62a, 62b, 62c (step S23). The group management control device 61 performs allocation control based on the door opening waiting time of each floor and the operation information acquired in step S22 (step S24).

Specifically, the group management control device 61 is based on the unanswered call information included in the operation information of each unit, and each of the cars 64a, 64b, 64c is between the current position and the floor where the landing call is generated. Determine which floor to stop at. The group management control device 61 selects the car that can reach the floor where the landing call occurs earliest as the assigned car in consideration of the door opening waiting time in the current time zone for the stop floor, and selects the car that can reach the landing call as the assigned car. Head to the generation floor (step S25).

As described above, according to the second embodiment, when the first embodiment is combined with the elevator group management system, the allocation car is selected in consideration of the door opening waiting time of each floor, thereby transporting efficiency. Can be raised.

According to at least one embodiment described above, it is possible to provide an elevator system capable of appropriately setting the door opening waiting time according to the user situation on each floor.
