Description

  The present invention relates to an elevator system and an elevator group management control method.

  Elevators transport many users smoothly and safely every day as a means of vertical movement in buildings. Particularly in a large building, since there are a large number of users, a plurality of elevators are installed, and these plurality of elevators are collectively managed as one group by a group management system.

Such a comprehensively managed elevator system requires the users on each floor of the building to control the elevator operation as efficiently as possible to reduce the waiting time at the user's landing. .
For such efficient elevator operation control, it is important to detect the status of the elevator landing with a sensor.

  For example, Patent Document 1 is known as an example of detecting an elevator landing using an imaging device. The technology described in Patent Document 1 is provided with an imaging device that images an elevator landing or its vicinity in an upper frame portion of the elevator platform, a curtain plate portion that forms the upper frame, or a landing call registration device. Yes. Then, the operation of switching the operation mode by discriminating the wheelchair user by the image recognition of the imaging device is performed.

  Patent Document 2 discloses an example in which a camera in a car detects a passenger waiting at the landing when the car arrives at the landing and the door is opened, and detects whether the passenger can get into the car. It is shown.

JP 2001-302121 A JP 2017-160001 A

  However, the technique described in Patent Document 1 captures an image of a user at a landing by providing an imaging device in the upper frame portion of the three-way frame of the elevator, the curtain plate portion forming the upper frame, or the landing call registration device. . In this method, since the elevator user himself can see well that the picture is taken, the elevator user himself may feel uncomfortable or disliked, and there was a problem that the actual introduction was difficult .

  Moreover, providing an imaging device in a three-way frame has many problems in terms of the design of the elevator. That is, the elevator platform is an important position in the building in terms of design, and the three-way frame is selected with emphasis on design as well as the platform door. For this reason, there is also a situation that it is not permissible for the owner or manager of the building to provide the imaging device in the three-way frame.

  In addition, since the landing call registration device is usually provided at a position lower than the average height of the user, if the imaging device is provided in the landing call registration device, the field of view is blocked by the user at the front and the imaging is performed. There is a risk that the range that the device can detect is limited. In particular, there are many cases where only a part of users near the door can be detected at the time of congestion such as at work or lunch.

  On the other hand, the technique described in Patent Document 2 is a method of detecting a passenger waiting at a landing when the car arrives at the landing and the door is opened by a camera in the passenger car. In this method, since passengers at the landing can be known after the car has arrived at the landing, there is a problem that the response is delayed. For example, even if it is detected that it is not possible to ride after the arrival of the car and the next car is pulled back to the floor, the passenger will wait for a long time until the next car arrives in addition to the time already waiting. have to wait.

  Patent Document 2 also shows an example in which a camera is installed on the ceiling of a landing place other than the car. However, in this case, the design of the landing site becomes worse, the user feels uncomfortable being photographed, and the power supply and communication to the ceiling camera must be routed inside the building etc. Many challenges remain.

  Based on the above problems, an object of the present invention is to provide an elevator system that can appropriately detect the situation of the elevator landing without giving the user unpleasant consciousness and without affecting the design of the landing. And an elevator group management control method.

In order to solve the above problems, for example, the configuration described in the claims is adopted.
The present application includes a plurality of means for solving the above-mentioned problems. To give an example, the present invention is an elevator system that operates by placing a user on a car at a landing, in the vicinity of an elevator landing door. And a guide device having both functions of a reservation guide light for notifying the user of the elevator number to be dispatched in response to the landing call and an arrival guide light for notifying the arrival of the elevator number at the landing point, A number detection device including a sensor provided in the guidance device and detecting a user waiting for the elevator car is provided.

  Further, the elevator system of the present invention is calculated by a landing number calculating device that calculates the number of landings based on detection information from one or a plurality of number detecting devices provided in the elevator of the landing, and a landing number calculating device. An elevator group management control device is provided for controlling the operation of the elevator car based on the number of landing users.

  And in the elevator system of the present invention, two or four people detection devices are arranged on the diagonals on both ends of the elevator hall, and all the detection areas of these people detection devices are the entire hall. The number-of-people detection apparatus is arranged so that the number-of-people detection direction is toward the center of the ride.

According to the present invention, it is possible to appropriately detect the status of the elevator landing without adversely affecting the design of the landing without causing the user to be aware that the photograph is being taken, so that the operation efficiency of the elevator is remarkably improved. Can be made.
Problems, configurations, and effects other than those described above will become apparent from the following description of embodiments.

<Embodiment example of the present invention>
Embodiments of the present invention will be described below in detail with reference to the drawings.
FIG. 1 is a diagram showing an overall configuration example of an elevator system according to an embodiment of the present invention (hereinafter referred to as “this example”). FIG. 1 shows the state of an elevator landing when detecting the number of users on any floor in a building.

  As shown in FIG. 1, the elevator system of this example includes a hall lantern 1, a number detection device 2 incorporated in the hall lantern 1, an elevator landing door 3, a three-way frame 4 surrounding the landing door, and a landing call button 5. Is provided. Here, since the hall lantern 1 includes a reservation guide light and an arrival guide light for the elevator car, it can also be referred to as a “guide device”.

  Further, FIG. 1 shows a detection direction 2a of the elevator user 6 and the number of people detection device 2 and a detection area 7 (a region sandwiched between two dashed lines). Furthermore, the elevator system of this example controls the operation of the elevator system based on information from the boarding number calculation device 8 and the boarding number calculation device 9 that detect the boarding number based on information from the plurality of people detection devices 2. An elevator group management control device 9 is provided. The elevator hall 10 includes a guide line 11 for a user waiting at the landing, and a waiting area 12 that matches the field of view of the number detection device 2 defined by the guide line 11.

The example of FIG. 1 is an example in which a number detection device 2 having a number detection function is incorporated in the hall lantern 1 installed in the three-way frame 4 or in the vicinity of the three-way frame 4 in the elevator platform 10. Here, the three-way frame 4 is a name including three frames, that is, the left and right frames of the landing door 3 and the upper frame. The number detection device 2 will be described in detail with reference to FIG.
First, when the hall call button 5 is pressed and a hall call is newly registered, the hall lantern 1 of the elevator number assigned to the hall call by the elevator group management control device 9 emits light (lights up). In other words, the hall lantern 1 serves as a guide device that notifies that the elevator number is called on the floor.

  For this reason, the hall lantern 1 is sometimes referred to as a reservation guide lamp in order to make an allocation reservation for elevators. In particular, in the elevator group management of the immediate reservation method in which the elevator car is reserved and guided immediately at the landing call registration, the hall lantern 1 continues to be lit from the call registration to the arrival of the elevator car, so the user can select the reserved elevator car. It can be confirmed at any time.

In addition, even when performing group management of elevator cars that do not have an immediate reservation function, the hall lantern 1 that is a guidance device emits light immediately before arrival of the assigned elevator car and notifies the arrival, so the hall lantern 1 Also called arrival guide light.
Hereinafter, the hall lantern 1 will be described as a guide device having functions including a reservation guide light and an arrival guide light. Note that the number-of-people detection device 2 may be configured by a laser sensor, an infrared sensor, a heat detection sensor, or the like in addition to a normal camera provided with an image sensor.

  Returning to FIG. 1 again, the description will be continued. The number detection device 2 is provided inside the hall lantern 1 and detects the number of users 6 waiting in front of the elevator number guided by the hall lantern 1.

Here, the following 1) -5) are mentioned as an advantage which provides the number-of-people detection apparatus 2 in the hall lantern 1. FIG.
1) As shown in FIG. 1, the user 6 waits for the elevator at the position where the hall lantern 1 can be seen in order to confirm the reserved elevator and the arrival time, so the hall lantern 1 is installed. It is easy to confirm the user 6 from the position where the user is located.
2) Since the number-of-people detection device 2 is stored inside the hall lantern 1, the number of users 6 can be detected without causing the user to feel uncomfortable about being photographed.
3) Since the hall lantern 1 is at a high position so that it can be easily seen from the user 6, it is easy to look down on the user 6 at the landing, and a blind spot that blocks the field of view of the number detection device 2 is unlikely to occur.

4) The hall lantern 1 is provided with a power supply line for light emission and a communication line for controlling the timing of turning on, turning off, and blinking from the building. Eliminates the need for troublesome wiring work and processing work.
5) Since the number-of-people detection device 2 is housed inside the hall lantern 1, the design of the landing is not damaged and the design of the building is not adversely affected.

  Data detected by the number-of-people detecting device 2 provided in the hall lantern 1 is collected in the landing number-of-people calculating device 8 through a communication line. The boarding number calculation device 8 combines the data from the number detection devices 2 of a plurality of elevators at the landing 10 on the floor to calculate the final detection value of the number of users at the landing 10.

  The detected value of the number of users is transmitted from the landing number calculation device 8 to the elevator group management control device 9. In the elevator group management control device 9, based on the detected value of the number of users, it is determined whether or not there is no leftover due to the full capacity of the car scheduled to be assigned to the platform 10. Then, when it is determined that an unloading occurs, the elevator group management control device 9 performs additional allocation of a new elevator number to the floor in advance.

  As a result, particularly when the elevator landing 10 on the floor is congested, it is possible to avoid a situation where the user 6 waits for a longer time due to unloading due to a full space, so that the operation efficiency of the elevator number can be improved. Is possible. The elevator group management control device 9 is a control device for optimally managing the operation of the plurality of elevator machines, particularly when there are a plurality of elevator cars at the landing 10.

As described above, the hall lantern 1 is provided in the vicinity of the landing doors 3 of the elevators at the landing 10. In the elevator system of this example, a form in which the number detection device 2 is incorporated in all or some of the hall lanterns 1 in the same hall 10 can be considered. It is not always necessary to provide the number detection device 2 in every hall lantern 1.
Therefore, it is possible to perform control with variations on how to use which of the plurality of person detection devices 2 in the landing 10 and how to detect the landing user more efficiently and with high accuracy. The control of the plurality of person detection devices 2 is executed by the elevator group management control device 9.

  Returning to FIG. 1 again, the description will be continued. For example, in the case of a camera having an image sensor, the number of people detection device 2 in the hall lantern 1 is a landing door of an elevator car in which the hall lantern 1 is installed rather than the angle 2a in the field of view of the image sensor. It is good to incline so as to face the direction of 3 side. The reason is that, as the psychology of the user 6, there is a desire to get on the reserved elevator machine as quickly as possible, and there is a tendency to wait near the landing door 3 of the elevator machine.

  For this reason, if the direction 2a of the field of view of the sensor is directed in a region around the hall lantern 1 of the elevator number where the landing is called and close to the landing door 3, the user 6 can be easily detected. The view direction 2a of the number detection device 2 shown in FIG. 1 represents such an example.

  Furthermore, as shown in FIG. 1, if a waiting area 12 that matches the field of view of the number detection device 2 is provided with the guide wire 11 for the user 6 waiting at the elevator landing 10 facing the landing door 3, the accuracy is improved. The number of users 6 can be detected. In this case, the guide line 11 for the user 6 is provided in the vicinity of the hall lantern 1, and it is important to make the standby area 12 set by the guide line 11 coincide with the detection area 7 of the number detection device 2.

  As described above, according to the elevator system including the number-of-people detection device 2 combined with the hall lantern 1, the user 6 does not unconsciously feel uncomfortable, and the design (design) of the landing 10 There is no negative impact. Furthermore, since the power supply line and the communication line can be easily secured, and the number of users 6 waiting at the landing 10 can be detected from a position close to the user 6 waiting for the elevator at a position where the number of people detection is high. It can be detected easily and with high accuracy. Moreover, since the additional elevator number can be promptly assigned at the time of congestion based on this detection information, the operation efficiency of the elevator can be increased.

  In the example of FIG. 1, the number detection device 2 provided in the hall lantern 1 is used to detect the number of users 6 at the landing 10. However, when a camera having an image sensor is used as the number-of-people detection device 2, the number-of-people detection device 2 can be used not only for detecting the number of people on the platform but also for detecting the status of the elevator platform 10 as a whole. For example, whether the user 6 at the landing 10 is about to get into the car or not can be determined from the user's operation status.

In particular, since the user 6 who is going to get into the car is likely to see the hall lantern 1 for confirmation, the image sensor in the hall lantern 1 recognizes the line of sight of the user 6 and moves to the elevator car. It is also possible to determine boarding.
It is also an important function to detect that there is no person (unmanned) in the entire platform 10. For example, if it is known that the entire platform 10 is unmanned, if there is an elevator that arrives at the platform 10 at the final car call, if all passengers in the cage have got off, the waiting for the door opening time to expire You can start immediately without closing the landing door. As a result, useless door opening time can be eliminated, so that the operation time of the elevator can be shortened.

In addition, even if a landing call is registered by mistake or when a landing call is registered by mischief, it can be determined in advance, and the allocation of the elevator number to that floor is canceled to suppress useless driving You can also
Such unmanned detection of the landing 10 requires that the entire elevator station landing be widely detected. For this reason, the number detection device 2 of the hall lantern 1 of all elevator stations at the landing 10 is operated. Thus, it is conceivable to detect the entire platform 10. Thus, the point that the entire hall 10 can be easily detected is also an advantage of providing the number-of-people detection device 2 in the hall lantern 1.

<Processing function of elevator system in this example>
FIG. 2 is a diagram for explaining the entire processing from the number detection device 2, the landing number calculation device 8, and the elevator group management control device 9 in the elevator system of this example shown in FIG.
As shown in FIG. 2, here, the number detection device 2 will be described as being provided in all elevators at the landing 10 on each floor. However, as already explained, it is not necessary to provide the number detection device 2 in all elevator elevators at the landings on each floor, and the number of people detection devices 2 provided in the hall lantern 1 of the elevator numbers on all floors is as follows: It doesn't have to be the same. The number of people detection devices 2 installed can be changed as appropriate according to the usage status of elevator elevators on each floor.

As shown in FIG. 2, the number detection device 2 installed in the elevator landing 10 on each floor includes a detection unit (camera) 20 and a number calculation processing unit 21. The number of people calculation processing unit 21 includes a head detection processing unit 22 and a count processing unit 23.
Also, the landing number calculating device 8 calculates the number of users 6 at the landing 10 when there is a landing call. That is, the boarding number calculation device 8 is based on the information from one or a plurality of number detection devices 2 provided at the halls 10 on each floor, and the users 6 at the halls 10 around the assigned elevators for the hall calls on each floor. Calculate the number of people. The calculation of the number of users is performed by the landing number calculation processing unit 81 of the landing number calculation device 8.

  Further, the elevator group management control device 9 includes a leftover occurrence prediction processing unit 91 and an additional allocation processing unit 92. In FIG. 2, the elevator group management control device 9 and the landing number calculating device 8 are described separately, but these can also be realized as one computer system. In FIG. 2, the fact that the boarding number calculation device 8 and the elevator group management control device 9 are surrounded by a one-dot chain line (not indicated) indicates that it can be realized as one computer system. In other words, some functions in the elevator group management control device 9 can be used for calculating the number of passengers. In such a case, the hall number calculation device 8 and the elevator group management control device 9 can be collectively referred to as an elevator group management control device in a broad sense.

  First, the state of the platform 10 near the assigned elevator number is photographed by the detection unit (camera) 20 of the number detection device 2. Then, the head detection processing unit 22 of the number calculation processing unit 21 detects the head of the user 6 at the landing 10 from the captured image. In addition, since a well-known technique is used about the detection of the user's 6 head, it is not explained in full detail here.

The number of heads of the user 6 detected by the head detection processing unit 22 is supplied to the count processing unit 23, where the heads of the user 6 are counted and the user 6 of the landing 10 is counted. The number of people is calculated. The calculation process of the number of landing users 6 is performed by the number detection device 2 installed in the elevator number on each floor where the landing call is made, thereby detecting the number of users 6 at the landing 10 waiting for the assigned elevator number. Is done.
However, as will be described later, the detection of the number of users 6 at the landing 10 is not necessarily performed only by the number detection device 2 arranged in the assigned elevator. A method of accurately detecting the number of users 6 at the landing 10 using information from a plurality of people detection devices 2 installed at elevators provided at the landings 10 is also conceivable. The elevator group management control device 9 controls which number of passengers is detected using information from the number detection device 2 installed in which elevator.

  The number of landing users 6 detected by the number detection device 2 installed in the elevator landing 10 on each floor, that is, the number of users 6 on the landing floor 10 where the landing call is made, is set in each floor floor. It is supplied from the number detection device 2 to the landing number calculation device 8. In other words, the boarding number calculation device 8 determines the value of the boarding number detected by the number detection device 2 in front of the elevator on each floor, the board call information of each floor controlled by the elevator group management control device 9, and the assigned elevator for the call. The number of users 6 at the landing 10 is calculated based on the information on the number machine.

  Here, a case will be described as an example where, when an upward landing call is generated on the third floor, the number of users 6 for the third floor upward landing call is calculated. Here, it is assumed that the assigned elevator number on the third floor is the second elevator. In this case, there is a high possibility that the user 6 at the landing 10 on the third floor is waiting in front of the second elevator which is the assigned elevator. The same applies to the case where the second assigned car is being guided in the immediate reservation guidance system in which the hall lantern 1 of the assigned elevator is immediately turned on when the landing call button is pressed.

  At this time, based on the number of people detected by the number detection device 2 of the elevator floor 10 on the third floor, the number of users 6 waiting in front of the second elevator machine that is the assigned elevator car is calculated. And as already explained, when detecting the number of users at the landing 10 on the 3rd floor, only the elevator number 2 number detection device 2 may be used, but the elevator number around the elevator number 2 or the facing elevator You may make it use the number detection apparatus 2 of a machine.

  In other words, the number of users 6 at the landing 10 can be calculated using the number detection device 2 attached to a plurality of elevators at the landing 10. However, in this case, the same person may be detected by the number detection device 2 provided in a plurality of elevators. In such a case, counting is performed by eliminating duplication of the same person by a known method. .

  The detection process for eliminating the duplication is a process in the case where the number of people detecting devices 2 around the assigned elevator number is detected, and this deduplication processing is the number-of-places calculating process of the boarding number calculating device 8. This is performed by the unit 81. That is, when the elevator call of the elevator number is made, the landing number calculation processing unit 81 of the landing number calculation device 8 performs duplication by processing the number detection values from the plurality of number detection devices 2 around the assigned elevator number. The number of excluded users is calculated. Note that the hall call information on each floor and the information related to the elevator number assigned to the call are transmitted from the elevator group management control device 9 to the hall number calculating device 8 by communication.

  The elevator group management control device 9 uses the number-of-users data of the user 6 for each landing call sent from the landing number calculation device 8, and the unloading occurrence prediction processing unit 91 causes the unloading user who has not been able to get on the car at the landing 10 to the left. Predict the occurrence of This prediction is performed on the basis of the predicted value of the number of people in the car, the number of landing calls, and the number of people who can board the car. The details of the processing performed by the unrecorded occurrence prediction processing unit 91 will be described later with reference to the flowchart of FIG.

When it is predicted by the unloading occurrence prediction processing unit 91 that an unloading of the user 6 has occurred, the additional allocation processing unit 92 adds an assigned elevator number that is directed in the direction (upward or downward) of the floor. .
As described above, the number of users 6 with respect to a landing call generated on a certain floor can be determined by providing the configuration including the number-of-people detection device 2, the landing number calculation device 8, and the elevator group management control device 9 shown in FIG. Can be detected more accurately. At this time, it is important to narrow down the number of users 6 to an appropriate area before the assigned number. Further, even when many of the users 6 are left behind using the information regarding the number of users of the landing call, an additional elevator number is allocated in advance by prediction. As a result, the waiting time of the user 6 can be significantly shortened.

<Description of the internal structure of Hall Lantern 1>
FIG. 3 shows a structural example of a hall lantern 1 that functions as a guide device (reservation guide light) in the elevator system (see FIG. 1) of this example. 3A is a front view of the hall lantern 1, and FIG. 3B is a side view. The example of FIG. 3 is an example of a structure in which the number-of-people detection device 2 is provided in the hall lantern 1, and the number-of-people detection device 2 is disposed on the bottom of the hall lantern 1. The example in FIG. 3 is merely an example, and as will be described later, the hall lantern (guidance device) 1 with the number detection device 2 used in the elevator system of the present example is not limited to this example.

  As shown in FIG. 3A, a reservation guide lamp as a guide device includes a hall lantern 1, a cover 1a that covers the light emitting portion of the hall lantern 1, and a cover 1b that covers the number of people detection device 2 below the hall lantern 1. , A dummy cover 1c on the upper side of the hall lantern 1 is provided. In addition, the reservation guide lamp includes a downward light emitting unit 1d for notifying reservation guidance for an elevator heading downward, and an upward light emitting unit 1e for notifying reservation guidance for an elevator heading upward. Further, a light shielding plate 1 f for blocking light from the light emitting portion of the hall lantern 1, a polarizing plate 1 g for blocking light from outside light, and a number detection device 2 are provided.

  Next, as shown in FIG. 3B, in addition to the above, the reservation guide lamp used in the elevator system of the present example is common to the hall lantern 1 main body composed of the light emitting sections 1d and 1e and the number detection device 2. Circuit board 1h. The hall lantern 1 has a power line 1i that supplies power to the circuit board 1h, and a communication line 1j that connects the circuit board 1h and the boarding number calculation device 8 or the elevator group management control device 9.

  In addition, as shown in FIG. 3A, the number detection device 2 is provided at the lower bottom of the hall lantern 1. If it is the position of this lower side bottom part, when detecting the condition of the boarding place 10, there is nothing which obstructs a visual field, and the thing which obstructs the light from the hall lantern 1 can also be decreased. The covering cover is composed of three parts. That is, the cover 1a that covers the light emitting portions 1d and 1e of the hall lantern 1 main body, the cover 1b that covers the number detection device 2 at the bottom bottom of the hall lantern 1, and the dummy cover 1c on the upper ceiling of the hall lantern 1.

Here, the cover 1b covering the number-of-people detecting device 2 must pass through the field of view of the number-of-people detecting device 2 such as a camera. Therefore, the cover 1b is preferably made of a material such as acrylic resin and a color that makes it difficult to see the internal camera. The cover 1c is provided as a dummy so as to maintain the vertical symmetry of the appearance of the hall lantern 1, and has the same appearance as the cover 1b.
By providing a cover having such a structure, the number of people detection device 2 can be made difficult to be noticed by the user 6, and the design of the appearance of the hall lantern 1 can be maintained in the same form as the conventional one.

Further, when the photographing device included in the number-of-people detection device 2 is an image sensor such as a camera, detection of the user 6 is hindered by light from the light emitting portions 1d and 1e of the hall lantern 1 and lighting from the landing. May be. In order to prevent this, the hall lantern 1 used in the elevator system of the present example is provided with a light shielding plate 1f and a polarizing plate 1g.
The light shielding plate 1 f is disposed between the light emitting portion 1 d of the hall lantern 1 and the number of people detection device 2 and has a function of preventing light from the hall lantern 1. The polarizing plate 1g is provided to prevent the influence of ambient external light.

  In particular, as shown in FIG. 3, when the number detection device 2 is provided at the lower bottom of the hall lantern 1, the light shielding plate 1f and the polarizing plate 1g are provided without interfering with the visibility of the landing 10 located below the hall lantern 1. It is convenient because it can be arranged.

Next, as shown in FIG. 3 (B), a power line 1i and a communication line 1j provided in the hall lantern 1 of the conventional elevator system are newly added in the elevator system of this example. Is shared.
For this reason, as shown in FIG. 3B, a common circuit board 1h for the hall lantern 1 main body (comprising the light emitting portions 1d and 1e) and the number of people detection device 2 is provided. Then, the power supply line 1i and the communication line 1j are wired on the circuit board 1h and distributed on the common circuit board 1h so that the hall lantern 1 and the number-of-people detection device 2 are used.

Further, as described in the background art section, if the number detection device 2 is installed alone on the wall or ceiling of the elevator hall, it is difficult to ensure power supply and communication. In particular, since it is necessary to supply power by wire, construction on the hoistway side and building side for wiring is newly required.
However, in the example of FIG. 3, since the wiring used in the hall lantern 1 used in the original conventional elevator system is used, no special wiring work for the number-of-people detection device 2 is necessary.

  Further, there is an advantage that the hall lantern 1 may be replaced with the hall lantern 1 with the number detection device 2 from the conventional one without changing the wiring or the like in the existing elevator. In particular, it is advantageous to retrofit the existing hall lantern 1 with the number-of-people detection device 2 so that the hall lantern 1 of this example can be obtained. That is, in the case of a building that becomes very crowded after the elevator elevator in the building is operated, the number of people on the landing 10 can be easily detected by replacing the hall lantern 1 with the number detecting device 2 as shown in FIG. This increases the possibility of improving operational efficiency.

  As shown in FIG. 3B, the direction 2a of the field of view of the number detection device 2, that is, the direction 2a of the lens is inclined downwardly from the landing 10 (see FIG. 1) when viewed in a vertical plane. Yes. Thereby, when the number detection device 2 is provided at the lower bottom portion of the hall lantern 1, it is possible to detect the user 6 waiting in the vicinity of the landing door immediately below the number detection device 2. Therefore, the shooting angle of the number detection device 2 can be determined so that the detection area includes the vicinity of the landing door and the center of the landing 10, and the number of users 6 can be detected more accurately. Become.

<Processing procedure of elevator system in this example>
FIG. 4 is a flowchart showing a procedure of the number-of-people detection process for the user 6 at the landing 10 regarding the elevator system shown in FIG. FIG. 4 shows a series of processes for detecting the number of people using a hall lantern with the number of people detection device 2.

  First, it is determined whether there is a new landing call registration on the target floor (S1). If there is no new landing call registration (No in S1), it waits until there is a new landing call registration. When there is a new landing call registration (Yes in S1), an elevator number is assigned to the landing call and the hall lantern 1 of the assigned elevator number is turned on (S2). Then, it is checked whether or not the hall lantern 1 is turned on (S3).

  If the hall lantern 1 is turned on in step S3 (Yes in S3), detection of the number of users 6 in the landing area in front of the landing door of the assigned elevator is started (S4). This number detection is performed by the number detection device 2 added to the hall lantern 1. That is, the number of people detection of step S4 is mainly performed using the number of people detection device 2 of the hall lantern 1 provided in the assigned elevator number. If it is determined in step S3 that the hall lantern 1 is not lit (No in S3), the process waits until the hall lantern 1 is lit.

  As described above, the number detection device 2 provided in the elevator number at the landing on each floor may be either one or a plurality, but the number detection value detected by the number detection device 2 is calculated as the number of people on the landing. After being processed by the device 8, it is transmitted to the elevator group management control device 9 (S5). Then, in the elevator group management control device 9, it is determined whether or not the number of landings 10 calculated by the landing number calculating device 8 exceeds the fullness determination threshold for the assigned elevator number (S6).

  When the determination in step S6 is a full determination and the occurrence of unloading is predicted (Yes in S6), an elevator elevator is additionally allocated to the floor (S7). Then, it is determined whether or not the car of the assigned elevator number has arrived at the landing (S8). If it is not determined in step S8 that the elevator car has arrived at the landing (No in S8), the process of detecting the number of people in step S5 is repeated until the elevator arrives at the landing 10. If it is determined in step S8 that the car of the assigned elevator number has arrived at the landing (Yes in S8), the elevator group management control device 9 is the detection mode with the number of people getting on and off the car. Switch to the number of people detection mode when the car arrives (S9).

  In addition, when the determination of step S6 is not a full determination (No of S6), the process of step S9 is performed without performing the process of step S7 and step S8. The reason for switching the number of people detection mode in step S9 is that there are both a user who gets off the car and a user who gets into the car when the assigned elevator number arrives. That is, if the assigned elevator number is before arrival at the landing, only the user 6 waiting at the landing needs to be detected, so the situation changes before and after the arrival of the assigned elevator number.

  Next, it is determined whether or not the assigned elevator has departed from the landing 10 (S10). If it is determined in step S10 that the assigned elevator number has departed from the landing (Yes in S10), the remaining number detection is performed to detect the number of unloaded items when the assigned elevator number is full. The mode is executed (S11). If it is determined in step S10 that the assigned elevator number has not left the landing 10 (No in S10), the process in step S9 is repeated.

In addition, in the process of step S7, the remaining allocation is predicted and the elevator unit is additionally allocated. However, when there are more leftovers than predicted or when there are fewer leftovers than expected, the leftovers are left. Detect the result of the number of people. Then, additional allocation is performed, additional allocation is changed, and additional allocation is canceled.
As a result, the remaining number detection mode ends after a predetermined time has elapsed, and the number detection for the assigned car number is ended (S12). Thereafter, the process returns to step S1 to repeat the detection of the number of people.

  As described above, by taking advantage of the characteristics of the number detection device 2 provided in the hall lantern 1, the number of people detection processing linked to the elevator control operation by the hall lantern 1 or the number detection device 2 can be performed more accurately. The number of elevator users at the platform can be detected, and as a result, the operation efficiency of the elevator can be improved.

  As described in the flowchart of FIG. 4, the feature of the elevator system of this example is that after the landing call registration, the elevator number assigned to the call is determined, and the hall 10 of the elevator number is used after the hall lantern 1 is turned on. The point is to start detecting the number of people.

  Further, in the group management control of the immediate reservation method in which the assigned elevator number is set immediately when the landing call button is pressed, when the hall lantern 1 is lit, there is a high possibility that the users 6 gather there. Therefore, more accurate detection of the number of users is possible if the number of persons is detected around the area of the assigned elevator number, that is, the position of the hall lantern 1 when the assigned elevator number is lit. In addition, during the passenger getting on and off after the assigned elevator arrives at the landing, detection is performed in a detection mode corresponding to the passenger. Further, if there is a user who has not been able to get in due to the full capacity of the car after departure, the number of persons will be detected as the remaining number.

<Description of operation of specific example of number detection process>
FIG. 5 is a time chart for explaining the operation of the number of people detection process corresponding to the flowchart of FIG. The time chart of FIG. 5 represents a time chart A1 showing the time lapse of the state of the hall lantern 1, a time chart A2 showing the time lapse of the state of the number detection process, and a time chart A3 showing the time lapse of the detected number of persons. ing. The time axis A4 of these three time charts is synchronized with the time charts A1 to A3.

  First, the time chart A1 of the hall lantern 1 shows two states of lighting and extinguishing, as indicated by the vertical axis A5. A new hall call is registered at the point of the symbol A5 on the vertical axis, the assigned elevator number is immediately selected, and the hall lantern 1 of the elevator number is turned on (A6). Thereafter, the hall lantern 1 continues to be lit (A7), and when it is before arrival of the elevator car of the assigned elevator (A8), the hall lantern 1 is in a blinking state (A9) in order to notify it.

  When the assigned elevator number arrives at the landing 10, it is turned off (at time A10). Thereafter, the hall lantern 1 remains off, the car is closed (at A11), and leaves the landing (at A12). Then, the remaining number of people process is completed (at time A13).

  A time chart A2 showing the passage of time in the state of the number of people detection process represents two states of turning on and off the number of people detection process, as indicated by the vertical axis A14. When the hall lantern 1 is turned on, the number detection is turned on (A15), and the number detection is turned off upon arrival of the assigned elevator. No special processing is performed in the period (A16) from the arrival of the assigned elevator to the door closing. In the flowchart of FIG. 4, the period from the arrival of the assigned elevator number to the door closing is a different number detection mode at the time of getting on and off (not shown). Then, after the elevator is closed, the number of persons is detected again in a predetermined time (A17). Here, the number of people left behind after departure of the elevator is detected.

  Next, a time chart A3 showing the elapsed time of the detected number of people represents the number of people detected on the vertical axis A18. The detection of the number of passengers is started from the time when the hall lantern 1 of the assigned elevator number is turned on and the number of persons detection process is turned on, and the number of users is detected as time passes as indicated by a curve A19. The alternate long and short dash line A20 is a fullness determination threshold value for the elevator car, and when the number of detected persons exceeds this threshold value (A21), the occurrence of unloading is predicted and processing for additional allocation of elevator cars is performed. I do.

  The number of persons continues to be detected until the assigned elevator number arrives (A22). The number data calculated by the boarding number calculation device 8 is sequentially transmitted to the elevator group management control device 9 and reflected in the group management control of the elevator number. Then, the elevator number restarts detection of the number of persons after the door is closed (A23), and detects the number of unreserved persons determined after a predetermined time (A24).

  As described above, in the elevator system of the present example, the timing for starting the number of people detection is extremely important, and this number of people detection timing is provided in the assigned elevator number after registration of a new landing call. After hall lantern 1 lights up. When the hall lantern 1 is extinguished when the assigned elevator car arrives, the detection of the number of people ends. During this time, the elevator group management control device 9 shares the communication line of the number detection device 2 and the communication line of the hall lantern 1 to perform group management control of a plurality of elevator units based on the number of users 6 at the landing 10. It can be carried out. Further, the landing number calculating device 8 can detect the number of users 6 more accurately and in a timely manner by such a temporal operation.

<Description of different structural example (second example) of hall lantern 1>
FIG. 6 shows an example of a hall lantern 1 (reservation guide light) according to the elevator system of this example, which has a structure different from that shown in FIG. 3 is different from the hall lantern 1 shown in FIG. 3 in that the number-of-person detection devices 2b and 2c are provided on both upper and lower sides of the main body (light emitting portion) of the hall lantern 1. As a result, the detection area of the landing 10 can be further expanded and the accuracy of detecting the number of people can be increased. Further, as will be described later, it is possible to appropriately avoid the light emitted by the hole lantern 1. In FIG. 6, the same components as those in FIG.

6 is different from FIG. 3 in that a number detection device 2c on the upper side of the light emitting unit which is the main body of the hall lantern 1 is provided. In accordance with this structure, similarly to the lower side, the cover 1b ₁ for the upper number detection device 2c, the light shielding plate 1f ₁ for blocking the light of the light emitting part of the hall lantern 1, and the polarizing plate 1g ₁ for avoiding the influence of external light Is provided. These components are the same as the lower cover 1b, the light shielding plate 1f, and the polarizing plate 1g.

In the hall lantern 1 having the structure shown in FIG. 6, light due to the emission of the hall lantern 1 can be further avoided. Specifically, the number of users 6 at the landing 10 is detected by the upper detection device 2c when the lower light emitting unit 1d is in the light emitting state, and the lower side when the upper light emitting unit 1e is in the light emitting state. The number of users 6 at the landing 10 is detected by the detection device 2b.
In this way, the upper number of people detection device 2c and the lower number of people detection device 2b are switched according to the lighting state of the upper light emitting unit 1e and the lower light emitting unit 1d, so that the influence of the light emission of the hall lantern 1 can be reduced. It can be avoided as much as possible.

  Furthermore, by dividing the detection areas of the upper number detection device 2c and the lower number detection device 2b, it is also possible to target a wider area of the landing 10. For example, the lower number detection device 2b detects a landing area near the hall lantern 1, and the upper number detection apparatus 2c detects a landing area far from the hall lantern 1. As a result, the entire region from the hall lantern 1 toward the landing 10 can be widely detected. As a result, for example, the present invention can be applied even when the area where the elevator user waits is very crowded.

<Description of different structural example (third example) of hall lantern 1>
FIG. 7 is a diagram showing a structural example (third example) different from the first example of FIG. 3 and the second example of FIG. 6 in the hall lantern 1 in the elevator system of this example.
In the third example, the number-of-people detection device 2 is arranged on the side surface of the light-emitting unit that is the main body of the hall lantern 1. In other words, the third example detects the situation of the landing 10 when it is difficult to arrange up and down as in the first or second example shown in FIG. 3 or FIG. It becomes an effective structure when it is easy. Also in FIG. 7, the same components as those in FIG.

  As described above, the part of the example of FIG. 7 that is different from the example of FIGS. 3 and 6 is that the number-of-people detection device 2 is arranged on the side surface of the light emitting part of the hall lantern 1. In accordance with this structure, similarly to the lower side, a cover 1k for the side surface side, and a light shielding plate 1m for blocking light from the light emitting portions 1d and 1e of the hall lantern 1 are provided. These components are the same as those of the cover 1b and the light shielding plate 1f provided on the lower side of FIG.

<Description of the method for detecting the number of passengers at the platform>
FIG. 8 is a diagram showing an example of the number of people detection processing method for detecting the number of users 6 at the landing 10 in the elevator system of this example shown in FIG.
The example shown in FIG. 8 shows a detection method for avoiding the influence of the light of the light emitting part of the hall lantern 1 when the number of people detection device 2 detects the number of people.

In the example of FIG. 8, a short turn-off period is provided when the hall lantern 1 is turned on, and the number of landings is detected during the turn-off period. The following three methods are conceivable.
1) A method of providing a short turn-off time every 5 to 10 seconds, for example, every 5 to 10 seconds, and detecting the number of landing user 6 while the lights are turned off.
2) In accordance with the increasing tendency of the number of users 6 at the landing, when the number of people increases in a short time such as when it is crowded, a light-off time is provided in a short cycle, and when the number of people hardly increases such as during a quiet time, the light is turned off with a long cycle A method of setting time and detecting the number of users 6 at the landing while the lights are off,
3) A method of providing a blinking period in which lighting and extinguishing are repeated in a short time, and detecting the number of users 6 at the landing while the blinking period is extinguished.

In any of the above methods 1) to 3), an extinguishing period is provided to detect the number of passengers at the landing while the light emitting part of the hall lantern is extinguished.
Hereinafter, an operation example of the processing related to the above 1) will be described with reference to FIG. FIG. 8 illustrates the processing operation of 1) above with two time waveform graphs, and the upper graph B1 shows the time waveform of the light emission state of the hall lantern 1. FIG.

On the other hand, the lower graph B <b> 2 shows a time waveform of the detection processing state of the number detection device 2. The horizontal axis B3 represents the same time axis as the upper graph B1.
First, the vertical axis B4 of the time waveform graph B1 of the light emission state of the hall lantern 1 indicates that there are two light emission states of the hall lantern 1, that is, the light-off state B5 and the light-on state B6.

As shown in the upper graph B1 in FIG. 8, short turn-off periods B8a, B8b, and B8c are provided between the turn-on periods B7a, B7b, and B7c.
In the lower graph B2, which is a time waveform graph of the detection processing state of the number detection device 2, the vertical axis B9 indicates the on / off state of the number detection processing. That is, two states of an on state B10 where the number of people is detected and an off state B11 where the number of people is not detected are shown.

  As already described, the number detection by the number detection device 2 is performed intermittently during the extinguishing period. This is because the number of passengers at the platform basically has a characteristic of increasing with time and is less likely to fluctuate greatly, so such intermittent detection is considered to be no problem. For this reason, the number of people detection apparatus 2 detects the number of people by intentionally providing the turn-off times B8a, B8b, and B8c as shown in FIG.

The turn-off time B8a of the hall lantern 1 shown in FIG. 8 may be as short as possible so as not to be mistaken for a failure by the user 6, but on the other hand, the number of passengers at the landing can be sufficiently detected within the turn-off time B8a. It is necessary to secure a long time.
Considering the characteristics of the human eye, for example, if it is 10 milliseconds or less, there is a high possibility that the user will not notice the turn-off time. Therefore, if the light extinction time is approximately 10 milliseconds or less, it may be possible to detect the number of users without the user noticing intermittent light extinction.

  If the turn-on time and the turn-off time of the hall lantern 1 are controlled as shown in FIG. 8, the light emitted from the hall lantern 1 poses a problem in incorporating the number of people detection device 2 into the hall lantern 1 and prevents the number of people from being detected. Can be prevented. This means that the hall lantern 1 can be turned on and off, and the number of people detection process 2 can be turned on and off on the elevator system side. Furthermore, it is known that there is no particular problem in terms of control even if the number of users is detected intermittently, for example, every 5 to 10 seconds.

<Specific example of the method for detecting the number of passengers at the landing (1)>
FIG. 9 shows a specific example (1) of the method of detecting the number of users at the landing in the elevator system of this example. FIG. 9 is a top view of the entire elevator hall as seen from above. Hereinafter, a method for detecting the number of users will be described with reference to FIG.

  As shown in FIG. 9, six elevator elevators 101 to 106 that are group-managed are arranged so as to face each other. That is, the first car 101, the second car 102, and the third car 103 are arranged on the left side of the landing 10, and the fourth car 104, the fifth car 105, and the sixth car 106 are arranged facing the right side of the landing 10.

  FIG. 9 shows a situation where a plurality of users 6 entering the elevator platform 10 from the platform entrance 14 are waiting in front of the elevator 2 102 assigned to the platform call. Here, as indicated by reference numerals 201 to 206, the hall lantern 1 is provided in each elevator unit (units 1 to 6).

  Here, in the example of FIG. 9, there is only one entrance to the landing 10 in a state where it cannot pass through the landing. In such a case, the normal hall lantern 1 is usually attached at a position that is easy to see from the entrance side. Accordingly, in the left elevators 101 to 103, the hall lanterns 201 to 203 are arranged on the left side of the elevator doors, and in the right elevators 104 to 106, the hall lanterns 204 to 206 are the elevator doors. It is arranged on the right side.

  In addition, it can be arbitrarily determined according to the situation of the landing 10 whether the hall lantern 1 is disposed on the left or right side of the landing door of the elevator. Even when there are a plurality of entrances to the platform 10 (for example, two places), the hall lantern 1 is arranged on the side close to the entrance where a relatively large number of users 6 enter (same as the example in FIG. 9). Sometimes. Further, in the left and right elevators, it is also conceivable to arrange the position where the hall lantern 1 is arranged, for example, on either the right side or the left side of the landing door.

In any case, among the hall lanterns 201 to 206, one or more hall lanterns 1 have the structure including the number-of-people detection device 2 shown in FIG. 3, and in the example of FIG. An example in which the left elevator No. 2 102 is assigned to a landing call of 6 is shown. FIG. 9 shows a state where the hall lantern 202 of the elevator No. 2 102 assigned by the landing call is lit.
Although the structure of the hole lantern 1 (202) is shown on the right side of FIG. 9, the structure of the hole lantern 202 is the same as the structure of the hole lantern 1 shown in FIG.

As described above, the hall lantern 202 of the No. 2 machine 102 that is the assigned elevator machine has the light emitting part 1d lit, and the user 6 gathers in front of the elevator No. 2 machine 102 assigned around the hall lantern 202. And wait for the arrival of the car.
The number detection device 2 is attached to the lower side of the hall lantern 202 of the elevator No. 2 102. The number detection device 2 has a detection area 7 surrounded by a one-dot chain line around the landing area around the No. 2 machine from this position. The number of users 6 at the landing 10 is detected.

  In the case where the number-of-people detection device 2 is a camera having an image sensor, for example, the center axis 2a in the detection direction of the sensor is inclined in the direction of the landing door 302 from the straight line 2d drawn in front of the hall lantern 202. It is set to face. As a result, the number detection device 2 can set the detection area 7 in front of the landing door 302.

  In general, the user 6 who is scheduled to board the second elevator 102 that is the assigned elevator waits at a position where he can visually recognize the hall lantern 202 and can easily enter the car. That is, as shown in FIG. 9, it is considered that the hall lantern 202 of the elevator No. 2 102 is gathered on the landing door 302 side of the No. 2 machine 102. For this reason, when the central axis of the detection direction is directed to the direction 2a inclined toward the landing door rather than the straight line drawn in front of the hall lantern 202 as described above, the number of users 6 can be detected more accurately. Can do.

  In addition, as shown in FIG. 9, when the number of people detection apparatus 2 attached to the hall lantern 202 of the elevator No. 2 102 which is an assigned number machine detects the number of people, it is necessary to take measures against emitted light from the hall lantern 202. That is, the operation for detecting the number of persons during the turn-off by providing the light-shielding plate 1f between the light-emitting portions 1d and 1e and the number-of-people detecting device 2 shown in FIG. 3 and the turn-off time (B8a to B8c) shown in FIG. The combination with is important.

  As described above, in the elevator system of this example, the image sensor used for the number-of-people detection device 2 installed in the hall lantern 1 is the elevator machine of the hall lantern 1 with respect to a straight line drawn straight from the hall lantern 1. The direction is inclined toward the landing door side. By doing so, it becomes possible to more accurately detect the number of users waiting for the arrival of the assigned machine.

<Specific example (2) of method for detecting the number of passengers at a landing>
FIG. 10 shows a specific example (2) of the method for detecting the number of users at the landing, which is different from FIG. 9, in the elevator system of this example. In FIG. 10, the same components as those in FIG.
In FIG. 10, the difference from FIG. 9 is that the number detection device 2 of the hall lantern 205 provided in the elevator No. 5 105 in the position facing the assigned elevator No. 2 102 is the number of the No. 2 machine 102 that is the assigned No. 102. The point is to detect the number of users 6 waiting for arrival.

In the specific example (2) shown in FIG. 10, the number detection device 2 of the hall lantern 205 of the No. 5 machine 105 located in the position facing the No. 2 machine 102 that is the assigned car is included in the detection area 7 surrounded by a one-dot chain line. The number of users 6 of the second machine 102 is detected.
Here, the detection direction 2e of the number-of-people detection device 2 of the hall lantern 205 may be set in the same manner as the method of determining the detection direction 2a described with reference to FIG.

The detection direction 2e of the number-of-people detection apparatus 2 in FIG. 10 is a direction in which the user 6 waiting for the assigned car can be detected from the position facing the second car 102, which is the assigned elevator car, in an appropriate field of view.
As in the example of FIG. 10, the advantage of detecting the number of people using the assigned elevator number from the number detecting device 2 of the facing elevator number facing the assigned elevator number is that the hall lantern 205 is not lit, and the influence of light This is a point that does not need to be considered. The right side of FIG. 10 shows an enlarged view of the hall lantern 205 of the elevator No. 5 105. As shown in this figure, since the light emitting portions 1d and 1e are not lit, a structure without a light shielding plate may be used. The structure of the number detection device 2 can be simplified.

<Overall Configuration Example of Elevator System of Second Embodiment>
FIG. 11 is a diagram showing an example of the overall configuration of an elevator system according to a second embodiment different from the first embodiment shown in FIG. A difference from FIG. 1 is that the number of people detecting device 2 of the hall lantern 1 provided in an elevator near the entrance 14 of the landing 10 is used to detect the user 6 at the landing 10. That is, in the example of FIG. 11, the user 6a who enters the landing 10 from the entrance 14 of the elevator landing is the detection target. In FIG. 11, the same components as those in FIG.

  As shown in FIG. 11, the number detection device 2 incorporated in the hall lantern 1 provided in the elevator number detects the user 6 a entering the landing 10, so that the detection direction 2 f faces the landing entrance 14. On the other hand, in the example of FIG. 1, the detection direction 2a of the number detection device 2 incorporated in the hall lantern 1 is directed toward the landing door 3 in order to detect the number of users 6 waiting for the arrival of the assigned elevator. Is different.

  In the example of FIG. 11, the hall lantern 1 with the number detection device 2 need only be installed in the vicinity of the landing entrance 14, so the number of hall lanterns 1 with the number detection device 2 can be reduced. That is, in the example of FIG. 11, the hall lantern 1 to which the number detection device 2 is attached may be attached to the elevator machine near the entrance 14 of the landing 10 to detect the user 6 a entering from the landing entrance 14. Then, by adding the number of users 6a entering from the landing entrance 14 to the number of users 6 at the landing 10, the number of users waiting for the elevator at the landing can be calculated. That is, instead of directly detecting the number of users 6, the number of users 6 at the landing 10 is estimated indirectly from the number of users 6 a entering the landing 10.

<Specific example (3) of method for detecting the number of passengers at a landing>
FIG. 12 shows a specific example (3) of the method for detecting the number of users 6 at the landing in the elevator system according to the second embodiment shown in FIG. FIG. 12, like FIG. 9, is a top view showing the situation where the entire elevator hall on a certain floor is viewed from above. In FIG. 12, the same elements as those in FIG.

  The example of FIG. 12 is an example in which the user 6a entering the landing is detected by the No. 1 machine 101 and the No. 4 machine 104, which are elevators close to the landing entrance 14. Specifically, the number of people detecting device 2 of the hall lantern 201 of the elevator No. 1 at the entrance 14 of the elevator and the number of people detecting device 2 of the hall lantern 204 of the elevator No. 4 are detected.

Here, the detection direction 2f of the number detection device 2 of the hall lantern 201 and the detection direction 2g of the number detection device 2 of the hall lantern 204 are respectively the direction of the landing entrance 14 with respect to the front direction of the hall lanterns 201 and 204. It is aimed. Thereby, the number of people who enter the landing 10 can be detected more accurately. The number detection device 2 of the hall lantern 201 has a fan-shaped range indicated by a one-dot chain line 7a as a detection area, and the number detection device 2 of the hall lantern 204 similarly has a detection area in the range of a one-dot chain line 7b.
By adding up the number of users 6a entering the landing 10 and the number of users 6 already at the landing, the total number of users 6 waiting for the arrival of the second elevator 102, which is the assigned elevator number, is obtained. It is possible to calculate.

<Number of persons detection method of elevator system in the second embodiment>
FIG. 13 is a flowchart for explaining the process of detecting the number of users 6 at the landing 10 in the elevator system according to the second embodiment shown in FIGS. 11 and 12.
As described below, the user 6a entering the landing 10 from the landing entrance 14 is detected by the number detection device 2 of the hall lanterns 201 and 204 provided in the elevator No. 1 101 and No. 4 104 at the landing entrance 14. Is called.

First, it is determined whether or not the number of people detecting devices 2 of the hall lanterns 201 and 204 has detected the user 6a entering from the entrance 14 of the landing 10 on the floor (S21). If a person entering from the entrance 14 is detected (Yes in S21), the number of persons ΔP entering is detected (S22).
Then, using this detected number of people ΔP, the estimated value P of the waiting number of people at the landing is updated by equation (1) (S23).
P = P + ΔP (1)
If no person entering from the entrance 14 is detected in step S21 (No in S21), the process waits until it is detected.

  Next, it is determined whether or not the car of the assigned elevator number called by the landing call has arrived at the landing 10 on the floor (S24). When it is determined in step S24 that the assigned elevator car has not arrived (No in S24), the processes in steps S21 to S23 are repeated, and the arrival of the assigned elevator car is awaited.

If it is determined in step S24 that the assigned elevator number has arrived (Yes in S24), the number Q of people who have entered the elevator car from the floor is detected (S25). The number of people Q boarded in the car can be detected by the number of people detecting device at the landing 10 and the number of people detecting device (not shown) in the car. As the number of people detection device in the car, a well-known load sensor or a camera installed in the car is used.
Next, it is determined whether or not the assigned elevator car has left the floor (S26). The determination in step S26 is performed by the elevator group management control device 9 shown in FIG.

If it is determined in step S26 that the elevator car of the assigned elevator has departed (Yes in S26), the number of people R remaining at the landing 10 on the floor is calculated by equation (2) (S27). This number R corresponds to the number of passengers left without being able to ride because the car of the assigned car is full.
R = PQ (2)
Here, when R <0, R = 0.

Next, the number of people R remaining at the landing obtained from the equation (2) is set as a new initial value of the estimated number P of waiting people at the landing 10 (S28).
P = R (3)
If the boarding place 10 is not very crowded, the number R of passengers left without being able to ride is “0”. Therefore, the initial value P of the waiting person waiting number P that is newly set is the basic value. Become zero.
If the assigned elevator car does not leave in step S26 (No in S26), the process in step S25 is repeated.

Next, after a lapse of a predetermined time from the departure of the assigned elevator car, it is determined whether or not a new landing call has been registered at the landing 10 on the floor (S29). If there is no new landing call in step S29 (Yes in S29), there should be no person at the landing 10, and the waiting number estimate value P of the landing is reset to P = 0 (S30), and the process is performed. End and return to step S21.
If it is determined in step S29 that a new landing call has been made (No in S29), a new user 6 has appeared on the landing 10, so the processing in step S30 is skipped and the processing in step S21 is performed. Return to.

  As described above, the number detection device 2 is installed only in the hall lanterns 201 and 204 of the elevator No. 1 or No. 4 which is the elevator near the entrance 14 described with reference to FIG. However, the number of hall lanterns 1 with the number detecting device 2 having a large number of parts and a special structure can be reduced.

  In addition, when considering the entire building, on floors where more accurate number detection is required, such as the lobby floor where many people gather, hall lanterns 1 provided in all elevator units are equipped with a number detection device 2. It is also possible to do. The general floors other than the lobby are configured such that only the hall lantern 1 of the elevator at the entrance 14 is provided with the number detection device 2, and the number detection device 2 is secured while ensuring the necessary number detection accuracy. The number of attached hall lanterns 1 can be reduced.

<Specific example of the method for detecting the number of passengers at the landing (4)>
FIG. 14 is a diagram illustrating another example of a method for detecting the number of users 6 at the landing 10 in the elevator system of the present example.
FIG. 14 is also a top view of the entire elevator platform 10 on a certain floor as seen from above, like FIG. 9 and FIG. 12, and the same elements as those in FIG. 9 and FIG.

In the example of FIG. 14, all of the six elevators 101 to 106 in the landing 10 are hall lanterns 201 to 206 with the number detection device 2, and the entire landing is detected and used for waiting for the elevator car to be assigned. The number of persons 6 is detected.
As shown in FIG. 14, the number of people detection device 2 from the front, rear, and diagonal directions is given to the user 6 who has been called at the landing and is waiting for the arrival of the assigned elevator car (No. 2 car 102 in this case). The entire platform 10 is covered by the detection area. For this reason, in the example of FIG. 14, it is possible to eliminate the detection blind spot when detecting the number of users 6 at the landing 10. However, on the other hand, since there is also a duplication detection of the same person by a plurality of cameras, the deduplication process is performed by the boarding number calculating device 8 shown in FIG.

  Further, the assigned elevator number is known as the second number 102 from the information regarding the elevator group management in the elevator group management control device 9. For this reason, since the number of persons centering on the area in front of the assigned elevator No. 2 can be detected, the number of users 6 waiting for the elevator No. 2 102 can be detected more accurately.

  Furthermore, according to this method, by using the number detection device 2 installed at the hall lanterns 201 and 204 of the elevator at the entrance 14, the user heading to the assigned elevator 2 102 from the entrance 14 can also be recognized. Can do. For this reason, the total number of users 6 can be predicted at an early stage, and the occurrence of unloading can be predicted and dealt with earlier.

  In the example of FIG. 14, the total number of users 6 is the sum of the number of users 6 already waiting in front of the assigned elevator No. 2 102 and the number of users 6 a entering from the landing entrance 14. calculate. It should be noted that the processing for integrating the results of the respective number detection devices 2 as described above is executed by the landing number calculation device 8 shown in FIG.

  As shown in FIG. 14, when hall lanterns 201 to 206 with the number detection device 2 are installed in all elevators of the landing 10 on the floor, the entire landing 10 can be made a wide detection area. Then, by combining the detection results of the number detection device 2 installed in all these hall lanterns 201 to 206, the number of users 6 can be detected accurately with a wider field of view.

<Specific example (5) of method for detecting the number of passengers at a landing>
FIG. 15 is a diagram illustrating an example of a case where there is no person at the landing as a special example of the method for detecting the number of users 6 at the landing 10 regarding the elevator system of the present example. FIG. 15 is a top view of the entire elevator platform 10 on a certain floor as seen from FIG. 14, and the components are the same as those in FIG.

  FIG. 15 shows a state in which, for example, there is no user at the landing 10 after the car has stopped due to a car call that calls the destination floor and all passengers in the car have got off. In this situation, the elevator group management control device 9 can control the operation of each elevator so that the door of the elevator car is closed before the expiration time reaches the expiration time. . As a result, useless stop time can be eliminated, so that operation efficiency can be improved during busy working hours.

  Further, the elevator group management control device 9 has no people waiting at the landing 10, such as when a mischievous call is made, or even when there is a car call, all users 6 get on the first elevator car. In some cases, it can be detected and the landing call can be canceled. Accordingly, it is possible to reduce useless stops to the floor where the user 6 is not present at the landing 10, so that the operation efficiency can be improved.

  As described above, in order to detect the absence of people at the landing (the number of people is zero), it is necessary to detect the entire landing 10. At this time, since it is necessary to detect that the user 6a does not enter the landing entrance 14, in order to detect the landing 10 and the entrance 14, all the elevators 101 to 106 of the landing 10 are provided with the number detection device 2. It is preferable to install hall lanterns 201-206.

<Another structural example of the hall lantern 1 and the number of people detection device 2>
FIG. 16 shows another structural example of the hall lantern 1 in the elevator system of this example. As in FIG. 3, FIG. 16A is a front view, and FIG. 16B is a side view. Also in FIG. 16, the same elements as those in FIGS. 3 and 6 are denoted by the same reference numerals, and description thereof is omitted.

In the example of FIG. 16, instead of the number-of-people detection devices 2 b and 2 c shown in FIG. 6, power supply and communication connection ports (contact ports) 1 m and 1 n distributed from the power line 1 r and the communication line 1 s of the hall lantern 1 are provided. Prepare. Connection ports (contact ports) 1m and 1n serving as contact points for the power supply and communication are provided on the upper and lower sides of the hall lantern 1, respectively, and light shielding plates 1f and 1f are provided between the light emitting portions 1d and 1e of the hall lantern 1. ₁ is provided.

Further, covers 1o and 1p covering the light emitting portions 1d and 1e of the hole lantern 1 are provided at the lower portion and the upper portion. Connection ports (contact ports) 1m and 1n serving as contact points for the power supply and communication are on the same substrate as the circuit board 1q to which the power supply line 1r and the communication line 1s are connected to the hall lantern 1 main body. Share the line.
As described above, the number of people at the landing 10 is detected by attaching, for example, cameras and image sensors to the connection ports (contact ports) 1m and 1n that are the contact points of the power supply and the communication. be able to.

  Since the hall lantern 1 shown in FIG. 16 has a structure including a connection port (contact port) that serves as a contact point for power supply and communication, a camera, an image sensor, etc. can be freely attached or detached as necessary. There is an advantage that can be. For example, in the initial state, the elevator system is installed in the building with nothing connected to the connection ports (contact ports) 1m and 1n that serve as contact points for the power supply and communication. The detection device 2 can be attached.

For example, after installing the elevator system of this example in a building, when it is found that the landing on a specific floor is very crowded, the person detection device 2 is attached to the hall lantern 1 of the crowded landing 10 as a retrofit. Is also possible. Also, depending on the needs of the building, such as to increase the operating efficiency of the elevator, the number of people detection device 2 including a camera, an image sensor, etc. is retrofitted to one connection port (contact port) of the hall lantern shown in FIG. It can also be attached.
In this case, since a specific floor such as a lobby floor is very crowded, it is possible to detect the number of people by attaching a camera or an image sensor only to that floor, thereby improving the operation efficiency.

<Specific example (6) of method for detecting the number of passengers at a landing>
FIG. 17 is a top view for explaining a method of detecting the number of landing users in the elevator system according to the third embodiment of the present invention.
That is, in the elevator system of the second embodiment shown in FIGS. 11 and 12, there is only one entrance to the landing, but in the example of FIG. 17, there are two entrances to the landing 10. That is, the example which can pass through the platform 10 is shown. In FIG. 17, the same elements as those in FIG.

  As shown in FIG. 17, the elevator platform is provided with two places, an entrance 14a and an entrance 14b. In the example of FIG. 12, since there is only one entrance 14 to the landing 10, all people who enter the landing 10 from the entrance 14 may be considered as elevator users. However, in FIG. 17, since there are two entrances 14a and 14b, it is considered that there are people who use the elevator hall as a passage in addition to those who use the elevator.

  In this case, in order to accurately detect the user 6 waiting for the elevator car to come out of the visitors from the entrance 14a or 14b, the number of people entering and exiting from the entrance 14a and the entrance 14b is obtained by calculation. There is a need. That is, the number detection device 2 must be installed in all the hall lanterns 1 of the elevators at the entrance 14a and the entrance 14b of the platform 10, and the number of people entering and exiting both the entrance 14a and the entrance 14b must be detected. That is, it is necessary to detect both the total number of people ΔP entering the landing 10 and the total number of people ΔE leaving the landing 10.

Specifically, the number-of-person detection devices 2 are provided in the hall lanterns 201 and 204 of the elevator No. 1 101 and the elevator No. 4 104 at the landing entrance 14a, the hall lanterns 203 and 206 of the elevator No. 3 103 and the elevator No. 6 106 at the hall entrance 14b. Is installed. The total number of people ΔP entering the platform 10 is the sum of the number of people ΔPa entering from the entrance 14a and the number of people ΔPb entering from the entrance 14b.
In FIG. 17, the mounting positions of the hall lanterns 201 to 206 are on the left side of all elevators, but are arbitrarily determined based on the design of the landing 10 or the situation of the user 6 entering and leaving the landing 10. It can be decided.

Further, the total number of people ΔE exiting from the landing is the sum of the number of people ΔEa exiting from the entrance 14a and the number of people ΔEb exiting from the entrance 14b.
In addition, the number T of people who got off from the elevator number is included in the people leaving from the entrance 14a or the entrance 14b.

<Number of persons detection method of elevator system in the third embodiment>
FIG. 18 is a flowchart for explaining the process of detecting the number of users 6 at the landing 10 in the elevator system according to the third embodiment of the present invention having two doorways shown in FIG.
Hereinafter, the processing of the third exemplary embodiment will be described in detail with reference to FIG. The number of users at the landing is detected by the number detection device 2 provided at the hall lanterns 201 and 204 of the elevators 101 and 104 at the hall entrance 14a and the hall lanterns 203 and 206 at the elevators 103 and 106 at the hall entrance 14b. This is performed by the provided number detection device 2. Here, the platform near the entrance 14a will be described as the first platform, and the platform near the entrance 14b will be described as the second platform.

First, it is determined whether or not a person (ΔP) entering from the entrances 14a and 14b of the No. 1 and No. 2 landings is detected (S31). If no person entering the landing is detected in step S31 (No in S31), the process waits until a person enters the landing. When the entrance of a person is detected from the entrance of the landing in step S31 (Yes in S31), the number ΔP of people entering the landing 10 and the number ΔE of persons leaving the landing are detected (S32). However, in order to exclude the number of people who got off from the unit that arrived immediately before the first visitor was detected from ΔE, the detection of the first person to go out starts after a certain time after the first visitor detection. However, this fixed time is much shorter than the time for passing through the platform as it is.
Then, an estimated value P of the number of users 6 remaining at the landing 10 is calculated by the following equation (4) (S33).
P = P + ΔP−ΔE (4)

  Next, it is determined whether or not one of the elevator Nos. 101 to 106 No. 106 has arrived (S34). If any elevator has not arrived (No in S34), the processes in steps S32 and S33 are repeated until the elevator arrives. That is, the number of landing users 6 calculated by equation (4) is updated in real time until any elevator car arrives.

  If it is determined in step S34 that one of the elevators Nos. 101 to 106 of the elevator No. 1 has arrived (Yes in S34), the number of passengers Q (the number of passengers) who got on the elevator and the disembarkation The number of people T (number of people getting off) is calculated. This calculation is performed by a method similar to the method described with reference to FIG. 14 using the number detection device 2 provided in the hall lantern 1 of the hall 10 and a load sensor (not shown) provided in the elevator car. (S35).

Next, it is determined whether or not the elevator car that has been used for getting on and off has departed (S36). If the elevator number does not leave in step S36 (No in S36), the process in step S35 is repeated.
If the elevator has departed in step S36 (Yes in S36), the number of people R ′ remaining on the floor and the number of passengers R excluding the number of people getting off T from the number of people R ′ are expressed by Equation (5) and ( 6) Calculate according to the equation.
R ′ = P−Q + T (5)
R = PQ (6)
Here, R is the actual number of waiting persons. When R <0, R = 0 and R ′ = T.
Then, a new initial value of the estimated value P of the number of passengers is set using R ′ in the equation (5) (S38).
P = R '(7)

Next, it is determined whether there is no continuation or registration of a new landing call at the landing after a predetermined time has elapsed since the departure of the elevator in step S36 (S39).
If there is no continuation or registration of a new landing call in step S39 (Yes in S39), there should be no person waiting for the elevator at the landing 10 on that floor, and the waiting number estimate P for the landing on that floor is P = Reset to 0 (S40). If it is determined in step S39 that a continuation or new landing call has been registered (No in S39), the process returns to step S32.

  In FIGS. 17 and 18 described above, detection of the number of landings when there are two landing doors has been described. However, even when there are two or more landing doors, the number of landings is detected in the same manner. be able to. In the example of FIG. 17, the number detection device 2 installed in the hall lantern 1 of two elevators adjacent to the landing entrances 14 a and 14 b is used. If it is possible to cover the entire detection range, it may be installed only at one elevator number adjacent to the landing entrance. For example, in the example of FIG. 17, the number detection device 2 may be installed in the hall lantern 1 of each elevator elevator adjacent to the landing entrance 14a and the landing entrance 14b.

FIG. 19 is a conceptual diagram illustrating changes in the number of people waiting at the landing and the number of people in the car corresponding to the processing shown in the flowchart of FIG.
First, it is assumed that the process of step S32 in FIG. 18 is completed and five users 6 are waiting for the assigned elevator number at the landing 10 as shown in FIG. 19A (step in FIG. 18). P of S33 = 5).
At this time, it is assumed that three people are in the elevator car assigned to the elevator car in the situation immediately before arrival on the floor.

  Here, the number of people in the car is detected by a load sensor (not shown) installed in the car. As described above, instead of the load sensor, a camera may be disposed in the car, and the number of people in the car may be detected from an image captured by the camera.

FIG. 19B is a diagram showing a state where the elevator car of the assigned elevator arrives at the floor where the landing call is made and the door of the elevator car is closed. At this time, the estimated value of the number of users of the landing 10 remains the number of waiting people at the landing 5, and this is the final value of the number of landings. Thereafter, a person who gets off the platform from the platform and a person waiting at the platform are mixed, so there is a possibility that the number of users 6 at the platform 10 cannot be accurately detected.
Therefore, the number of halls before the door of the assigned elevator number is opened is determined as the final value of the hall user 6.

  FIG. 19 (c) shows a state where the assigned elevator car has arrived at the landing 10, the elevator car door has opened, and two passengers have exited. In FIG. 19 (c), two people who got off are indicated by dotted lines. The fact that two people got off the elevator car was calculated by the time change of the load sensor value, and it was found that the number of users in the car became one by the two getting off.

FIG.19 (d) has shown the state in which the user of the boarding area 10 boarded the elevator car of the assigned elevator number after FIG.19 (c).
That is, it is detected that the number of passengers in the car after boarding is 4 by the time change of the load sensor value installed in the car of the elevator car. From the difference between the number of load sensor values after the boarding is 4 people (see FIG. 19 (d)) and the load sensor value at the time of getting off the car is 1 person (see FIG. 19 (c)) It can be estimated that three people got in. In step S35 in FIG. 18, Q = 3 and T = 2.

In FIG. 19 (d), the two persons getting off, indicated by the dotted line in FIG. 19 (c), exit the doorway 14a or 14b (see FIG. 18) and are not in the landing 10.
Then, by subtracting three people (Q = 3) who got into this assigned elevator number from the estimated number of waiting people at the landing (5 = P = 5), the number of people left on the landing is two (FIG. 13). In step S27, it can be estimated that R = PQ = 2).

<Specific example (6) of method for detecting the number of passengers at a landing>
FIG. 20 is a top view showing a processing method when there are two entrances to the landing 10, which is the third embodiment of the present invention, as in FIG. FIG. 20 is different from the detection method of FIG. 17 in that the number of halls is detected using two hall lantern number detection devices provided on the two entrance sides of the elevator hall. In FIG. 20, the same elements as those in FIG.

  The difference between the detection methods of FIG. 20 and FIG. 17 is specifically the location of the number-of-people detection device 2 provided in the hall lantern 1 installed in the elevator of the hall 10 and its detection area. In the example of FIG. 20, among the hall lanterns 201 to 206 installed in six elevator units, the number detection device 2 is installed in the hall lantern 201 of the elevator No. 1 101 and the hall lantern 206 of the elevator No. 6 106. .

  As described above, in FIG. 20, the number of persons in each of the hall lantern 201 of the elevator No. 1 101 adjacent to the landing entrance 14b and the hall lantern 206 of the elevator No. 6 adjacent to the landing entrance 14a arranged on the diagonal of the landing are shown. A detection device 2 is installed. For this reason, in the example of FIG. 20, even when another person is photographed between the hall lantern 201 and the target person, the other person is photographed by the number detection device 2 of the hall lantern 206. It is possible to prevent false detection as a person. In other words, by using the two person detection devices 2 provided in the two hall lanterns 201 and 206, the blind spot of the target person is eliminated and a plurality of persons are not erroneously detected as one person.

  Furthermore, in FIG. 20, two people detection devices 2 for photographing the users of the landing 10 are provided, but the number of people is detected in four hall lanterns 1 (201, 203, 204, 206) of the elevator car at the four corners. It is also conceivable to provide the device 2. In this case, it can also be used as a stereo camera in which the detection areas of the four person detection devices 2 are directed toward the inside of the landing 10, thereby further improving the accuracy of detecting the number of persons.
