Hereinafter, embodiments will be described with reference to the drawings.
(First embodiment)
First, the first embodiment will be described.
FIG. 1 is a plan view showing a first example of an arrangement form in a boarding / alighting direction of sensors for passenger identification of an elevator car in the first embodiment.
A sensor 2, which is an infrared sensor for detecting passengers at the entrance / exit of the car, is attached to the car door panel 3 of the car room 1 of the elevator car in the present embodiment. The sensor 2 may be attached to the back angle of the car frame, for example. The sensor 2 may also be used as a sensor that has been used to detect a conventional obstacle.
FIG. 2 is a front view showing an example of an arrangement in the height direction of the passenger discrimination sensor of the elevator car in the first embodiment. FIG. 3 is a diagram illustrating an example of an arrangement in the height direction of the passenger discrimination sensor of the elevator car according to the first embodiment.
FIG. 2 is a front view of the doorway from the inside of the car. As shown in FIGS. 1 to 3, the sensors 2a, 2b, 2c, 2d, 2e, and 2f are used. The sensors 2a, 2b, 2c, 2d, and 2e are sensors 2a, 2b, 2c, 2d, and 2e from a height close to the floor of the car at predetermined intervals along the height direction of the car room 1 of the car. It is provided in the order. In the present embodiment, an example in which five sensors are provided along the height direction of the car cab 1 will be described. However, the present invention is not limited to this. For example, several tens of sensors such as 50 are provided in the car cab 1. You may make it provide for every predetermined space | interval along a height direction.
Each sensor 2 includes an infrared transmission unit and a reception unit, and is provided so as to be opposed to one and the other across the entrance / exit.
The transmitter of the sensor 2a transmits infrared rays having the optical axis 4a shown in FIGS. 2 and 3 to the receiver. The transmitter of the sensor 2b transmits infrared rays having the optical axis 4b shown in FIGS. 2 and 3 to the receiver. The transmission unit of the sensor 2c transmits infrared rays having the optical axis 4c shown in FIGS. 2 and 3 to the reception unit. The transmission unit of the sensor 2d transmits infrared rays having the optical axis 4d illustrated in FIGS. 2 and 3 to the reception unit. The transmission unit of the sensor 2e transmits infrared rays having the optical axis 4e illustrated in FIGS. 1 to 3 to the reception unit. Each sensor 2 outputs a detection signal of an object when the object blocks infrared rays.
  In addition, the sensor 2f is attached to a location where the sensor 2a is installed as viewed from the inside of the car room along the direction of getting in and out of the car room 1 and outside the location where the sensor 2a is installed as seen from the car room. The transmission unit of the sensor 2f transmits infrared rays having the optical axis 4f illustrated in FIG. 1 to the reception unit. The sensor 2f may be attached at a location adjacent to the mounting location other than the sensor 2a along the direction of getting in and out of the cab 1, so that a passenger with a short height or a bag with a low height can be detected. In addition, for example, it is desirable to be a location adjacent to the attachment location of any of the sensors 2a, 2b, and 2c along the direction of getting in and out of the cab 1. Further, as described above, a plurality of sensors may be attached in parallel along the boarding / alighting direction. For example, the sensor 2f is attached to a place adjacent to the place where the sensor 2a is attached along the direction of getting in and out of the car room 1, and another place adjacent to the place where the sensor 2b is attached along the direction of getting in and out of the car room 1 A sensor may be attached.
  The mounting location of the sensor 2f is outside the mounting location of the sensors 2a to 2e when viewed from the inside of the car. Therefore, when the passenger gets into the car room from outside the car room, the infrared optical axis 4f from the outer sensor 2f is blocked first, and any of the infrared optical axes 4a to 4e from the inner sensors 2a to 2e is blocked. I will block it later.
  When the passenger gets out of the car room from the car room, one of the infrared light axes 4a to 4e from the sensors 2a to 2e is blocked first, and the infrared light axis 4f from the sensor 2f is blocked later. It will be.
  In the present embodiment, the car cab 1 of the car is connected to a suspension weight via a sheave provided on a rotating shaft of a hoisting machine (not shown) and a main rope wound around the baffle sheave. As the sheave rotates by driving the hoisting machine, the car room 1 moves up and down in the hoistway in the opposite direction to each other along with the suspension weight by the frictional force between the sheave and the main rope. Moreover, the raising / lowering method of the cab 1 is not limited to the above-described rope suspension type, and may be a rope winding barrel type or a hydraulic type, for example.

In the example shown in FIG. 6, the sensors 2 a to 2 e are incorporated in the car entrance / exit column 5, and the sensor 2 f is attached to the inside of the door panel 3.
FIG. 7 is a block diagram illustrating an example of a functional configuration of the elevator control device for the elevator according to the first embodiment.
As shown in FIG. 7, the elevator control device 20 of the elevator of this embodiment includes sensor detection signal input units 21 a, 21 b, 21 c, 21 d, 21 e, 21 f, a sensor detection presence / absence recognition unit 22, a passenger type determination unit 23, a movement A direction determination unit 24, an operation control unit 25, and a storage device 26 are included.
  The sensor detection signal input unit 21a inputs a detection signal from the sensor 2a. The sensor detection signal input unit 21b inputs a detection signal from the sensor 2b. The sensor detection signal input unit 21c inputs a detection signal from the sensor 2c. The sensor detection signal input unit 21d inputs a detection signal from the sensor 2d. The sensor detection signal input unit 21e inputs a detection signal from the sensor 2e. The sensor detection signal input unit 21f inputs a detection signal from the sensor 2f.
The sensor detection presence / absence recognition unit 22 recognizes whether or not a detection signal is input by each of the sensor detection signal input units 21a to 21f.
Based on the recognition result by the sensor detection presence / absence recognition unit 22, the movement direction determination unit 24 determines whether the movement direction of the passenger passing through the entrance / exit of the car is boarding or getting off.
  The passenger type discriminating unit 23 discriminates the type of passenger passing through the entrance / exit of the car and its moving direction based on the recognition result by the sensor detection presence / absence recognizing unit 22 and the discrimination result by the moving direction discriminating unit 24, and By determining the type of passenger who gets on or off the car, the number of passengers currently in the car is determined for each type of passenger. In this embodiment, the type of passenger is classified into an adult, a child, a wheelchair user, and a passenger who carries luggage.
  The operation control unit 25 controls the raising / lowering of the car according to the call registration, and the passenger type discrimination unit 23 determines the number of passengers currently in the car for each type of the passenger. In addition, door opening / closing control suitable for this passenger type is performed.

The control program for memorize.
Next, the operation of the elevator having the configuration shown in FIG. 1 will be described.
FIG. 8 is a flowchart illustrating an example of a processing operation for determining a passenger type and a boarding / alighting direction by an elevator according to the first embodiment.
FIG. 9 is a diagram illustrating an example of a determination pattern of the passenger boarding / alighting direction by the elevator according to the first embodiment.
FIG. 10 is a diagram illustrating an example of a determination pattern indicating that the type of passenger by the elevator according to the first embodiment is an adult.
FIG. 11 is a diagram illustrating an example of a determination pattern indicating that the type of passenger by the elevator according to the first embodiment is a child.
FIG. 12 is a diagram illustrating an example of a determination pattern indicating that the type of passenger by the elevator according to the first embodiment is a wheelchair user.
FIG. 13 is a diagram illustrating an example of a determination pattern indicating that the type of passenger by the elevator according to the first embodiment is a passenger carrying a load.
In the initial state, it is assumed that the sensors 2a to 2f do not detect an object. When the passenger blocks the infrared rays from any of the sensors 2a to 2f (step S1), the sensor that blocks the transmitted infrared rays outputs a detection signal to the elevator control device 20.
  The sensor detection presence / absence recognition unit 22 recognizes the presence / absence of detection signal input by each of the sensor detection signal input units 21a to 21e, and recognizes that all of the sensor detection signal input units 21a to 21e are inputting detection signals. In the case (YES in step S2), the passenger type determination unit 23 does not change the recognition result from the start of recognition of the detection signal input to the end of recognition, as shown in FIG. 10, for example, the passengers are detected from the sensors 2a to 2e. If all of the infrared optical axes 4a to 4e are blocked (YES in step S3), it is determined that the passenger who blocked the infrared rays from the sensors 2a to 2e is an adult (step S4).
  When the sensor detection presence / absence recognition unit 22 recognizes the presence / absence of detection signal input by all of the sensor detection signal input units 21a to 21e (YES in step S2), the passenger type determination unit 23 starts the recognition from While the recognition that the detection signal is input by at least one of the sensor detection signal input units 21a to 21e is maintained, the recognition end of the detection signal input is recognized, that is, the sensor detection signal input unit. In the case where a change occurs in the recognition result of the detection signals from other sensors before the detection signals are input by all of 21a to 21e (NO in step S3), the infrared rays from the sensors 2a to 2e are blocked. The passenger is determined to be an adult carrying a luggage such as a carry bag (step S5).
  Specifically, in the case of determining “NO” in step S3, for example, at the start of recognition of the detection signal input, the passenger blocks all of the infrared optical axes 4a to 4e from the sensors 2a to 2e. After the start of recognition, the passenger does not block the infrared optical axes 4a, 4b, 4d and 4e from the sensors 2a, 2b, 2d and 2e, and then does not block the infrared optical axes 4c from the sensor 2c and from the sensor 2b. While the infrared optical axis 4b is again blocked, the infrared optical axis 4a from the sensor 2a is blocked again, so that the recognition of the detection signal input from any of the sensors 2a to 2e is maintained. This is a case where the presence / absence of recognition of the detection signal input of another sensor changes.
  In addition, when the sensor detection presence / absence recognition unit 22 recognizes that a detection signal from a part of the sensor detection signal input units 21a to 21e is input (NO in step S2), the passenger type determination unit 23 is, for example, 11, there is no change in the recognition result from the start of recognition of input of the detection signal to the end of recognition, that is, the passenger blocks the infrared optical axes 4a to 4c from the sensors 2a to 2c, and infrared rays from other sensors. If not blocked (YES in step S6), it is determined that the passenger who blocks the infrared rays from some of the sensors 2a to 2e is a child (step S7).
  In addition, when the sensor detection presence / absence recognition unit 22 recognizes that a detection signal is input by a part of the sensor detection signal input units 21a to 21e (NO in step S2), the passenger type determination unit 23 recognizes. From the start, the recognition that the detection signal is being input by at least one of the sensor detection signal input units 21a to 21e is maintained, and the recognition of the detection signal is started from the recognition start of the detection signal. If there is a change in the recognition result of the detection signal from another sensor before the input is stopped (NO in step S6), the passenger who blocks the infrared rays from some of the sensors 2a to 2e is a wheelchair user or shopping It is determined that the passenger is carrying a luggage such as a cart (step S8).
  Here, the passenger type determination unit 23 maintains the recognition that the detection signal is input by two or less of the sensor detection signal input units 21a to 21e from the start of the recognition. When a change occurs in the recognition result of the detection signal from another sensor from the start of input recognition to the end of recognition, it is determined that the passenger who blocks the infrared rays from some of the sensors 2a to 2e is a wheelchair user. .
  Specifically, for example, as shown in FIG. 12, the passenger type determination unit 23 recognizes that the passenger blocks only the infrared optical axes 4 a to 4 b from the sensors 2 a to 2 b at the start of recognition of the detection signal input. After the start, when the infrared optical axes 4c to 4d from the sensors 2c to 2d are further blocked, it is determined that the passenger is a wheelchair user.
  In addition, since the passenger type determination unit 23 maintains the recognition that the detection signal is input by four or less of the sensor detection signal input units 21a to 21e from the start of the recognition, the detection signal is input. When the recognition results of detection signals from other sensors change from the start of recognition to the end of recognition, passengers who block out infrared rays from some of the sensors 2a to 2e are passengers who carry luggage such as shopping carts. Determine that there is.
  Specifically, for example, as shown in FIG. 13, the passenger type determination unit 23 recognizes that the passenger blocked only the infrared optical axes 4 a to 4 c from the sensors 2 a to 2 c at the start of recognition of the detection signal input. After the start, when the infrared optical axes 4d to 4e from the sensors 2d to 2e are further blocked, it is determined that the passenger is a passenger carrying a luggage such as a shopping cart.
The sensor detection presence / absence recognition unit 22 recognizes the start timing of the detection signal input by each of the sensor detection signal input units 21a to 21f.
After discrimination in steps S4, S5, S7, and S8, as shown in FIG. 9, the detection target 6 first detects the sensor by blocking the infrared optical axis 4f from the outside sensor 2f when viewed from the inside of the car. The presence / absence recognition unit 22 recognizes that the detection signal input by the sensor detection signal input unit 21f corresponding to the sensor 2f has been input first, and as shown in FIG. Of the infrared rays from the inner sensors 2a to 2e described above within a predetermined time in which it can be considered that the infrared rays from the sensors 2a to 2e are continuously passed. If one of the sensor detection signal input units 21a to 21e corresponding to the sensors 2a to 2e recognizes that the detection signal is input later by blocking any of them later (step S9). ES), the moving direction discriminator 24, passengers blocking the infrared rays from at least a portion of the sensor 2a~2e is determined that passengers riding in the elevator car (step S10).
  Moreover, after discrimination | determination by step S4, S5, S7, S8, the sensor detection presence-and-recognition recognition part 22 recognizes the input of the detection signal by any of the sensor detection signal input parts 21a-21e first. When the detection signal input by the sensor detection signal input unit 21f is later recognized within a predetermined time during which the infrared rays from any of the sensors 2a to 2e and the infrared rays from the sensor 2f are considered to have passed continuously (in step S9) NO), the moving direction determination unit 24 determines that the passenger who blocks the infrared rays from at least some of the sensors 2a to 2e is a passenger who gets off the car (step S11).
  Passenger type determination unit 23 is a determination result before boarding or getting off when it is determined in step S10 that a passenger has entered the car or in step S11 that a passenger has got off the car. By adding or subtracting the number of passengers for each type in the car, the current number of passengers in the car after getting on or off the car is determined for each type, and the determination result is stored in the storage device 26. (Step S12).
  For example, if it is determined in step S10 that one passenger has entered the car, the passenger type determination unit 23 determines that the passenger type is a child in the car if the passenger type is determined to be a child in step S7. As a result, the determination result stored in the storage device 26 is updated to the determination result for each type of the current number of passengers in the car after boarding.
  In addition, if it is determined in step S11 that one passenger has got off the car from the passenger car, the passenger type determining unit 23 determines that the passenger type is a child in the car if the passenger type is determined to be a child in step S7. As a result, the determination result stored in the storage device 26 is updated to the determination result for each type of the current number of passengers in the car after getting off.
  When the car reaches the destination floor, the operation control unit 25 determines the door opening / closing speed of the car according to the type of the current number of passengers in the car, which is the discrimination result by the passenger type discrimination unit 23. Or the waiting time from the door opening to the door closing start is controlled (step S13).
  Specifically, the determination result indicating that the passenger type determination unit 23 determines that at least one child passenger is currently in the car at the time of landing of the car is the storage device 26. When the child gets out of the car, the operation control unit 25 opens and closes the door at a door opening / closing speed slower than the normal door opening / closing speed so that the child does not pose a danger. In addition, the door opening / closing control is performed so that the door is closed when various buttons are not pressed even after a normal waiting time until the door closing starts.
  In addition, at the time of landing of the car, the passenger type discriminating unit 23 has determined that one or more wheelchair users or one or more passengers carrying luggage are currently in the car. When the determination result shown is stored in the storage device 26, the operation control unit 25 prevents the passenger from getting caught in the door when the passenger is getting out of the car. The door is opened and closed at the normal door opening and closing speed, and the normal waiting time is extended from the opening of the door. If the call button in the car is not pressed even if this waiting time has passed, the door is closed. The door opening / closing control is performed as described above.
  Also, at the time of landing of the car, one or more children and one or more wheelchair passengers are both in the car or carry one or more kids and luggage in the car. When a determination result indicating that one or more passengers are on the vehicle is stored in the storage device 26, the operation control unit 25 is dangerous to the passengers when both passengers get out of the car. The door is opened and closed at a door opening speed slower than the normal door opening and closing speed, and the normal waiting time is extended from the door opening. Door opening / closing control is performed so that the door is closed when a button is not pressed.
  Further, as described above, when a passenger in the car gets off or gets into the car during the period from when the car arrives to the departure, the passenger type determination unit 23 takes the car or gets off the car. By adding or subtracting the number of passengers for each type, which is the previous determination result, the number of passengers in the car after getting on or off the vehicle is again determined for each type, and the operation control unit 25 Depending on the determination result, door opening / closing control is performed as necessary.
  As described above, in the elevator according to the first embodiment, the number of passengers in the car is determined for each type by determining the type of passenger who blocks the infrared rays from the sensor at the entrance of the car. When the car is landed, if a child is on the car, the door opening / closing control is performed so that the door opens and closes at the first door opening / closing speed slower than the normal door opening / closing speed. Safety and operation when the child passes through the doorway can reduce the risk of the child's hand being caught in the door pocket when the door is opened and the child's hand being caught in the door when the door is closed Efficiency can be improved.
  Also, if the passenger is a wheelchair user or a passenger who carries luggage, it is necessary to lengthen the waiting time until the door closes in order to smoothly get on or get off, in this embodiment, If there are wheelchair users or passengers carrying luggage in the car at the time of landing, the waiting time will be longer than the normal waiting time after the door opens, Since the door closing control is performed so that the door is closed when the call button in the car is not pressed, the convenience and safety when the wheelchair user and the passenger carrying the luggage pass through the entrance of the car are improved. Can do.

FIG. 21 is a flowchart illustrating an example of a processing operation for determining a passenger type and a boarding / alighting direction by an elevator according to the second embodiment.
In the initial state, it is assumed that the sensors 2a to 2e have not detected an object. When the passenger blocks the infrared rays from any of the sensors 2a to 2e (step S21), the sensor that blocks the transmitted infrared rays outputs a detection signal to the elevator control device 20.
Then, the classification of the passenger is determined by the processing from steps S2 to S8 described in the first embodiment.
  After the determination in steps S4, S5, S7, and S8, the load detection signal input unit 31 receives the signal input from the load detector 7 from the timing before the passenger blocks the infrared rays from the sensor 2 to the timing after the passengers block the infrared rays. If this signal is a signal indicating an increase in the load in the car (YES in Step 22), the moving direction determination unit 24 blocks infrared rays from at least a part of the sensors 2a to 2e. It is determined that the passenger is a passenger in the car (step S23).
Moreover, after discrimination | determination by step S4, S5, S7, S8, the load detection signal input part 31 input from the load detector 7 from the timing before a passenger shielded the infrared rays from the sensor 2 to the timing after the infrared rays were shielded. When the signal is recognized and this signal is a signal indicating a decrease in the load in the car (NO in step S22), the moving direction determination unit 24 receives infrared rays from at least a part of the sensors 2a to 2e. It is determined that the passenger who has blocked the passenger is a passenger who has got off the car (step S24).
Then, the processes of steps S12 and S13 described in the first embodiment are performed.

The image analysis unit 42 analyzes the image input by the captured image input unit 41.
FIG. 24 is a flowchart illustrating an example of a processing operation for determining a passenger type and a boarding / alighting direction by an elevator according to the third embodiment.
In the initial state, it is assumed that the sensors 2a to 2e have not detected an object. When the passenger blocks the infrared rays from any of the sensors 2a to 2e (YES in step S31), the sensor that blocks the infrared rays being transmitted outputs a detection signal to the elevator control device 20.
Then, the classification of the passenger is determined by the processing from steps S2 to S8 described in the first embodiment.
  After the determination in steps S4, S5, S7, and S8, the image analysis unit 42 reads out the images input within a predetermined time before and after the passenger blocks the infrared rays from the sensor 2 among the images stored in the storage device 26. Then, it is analyzed whether this image is an image in which a passenger passing through the entrance moves toward the inside of the car or an image that moves toward the outside of the car, and the analysis result is output to the moving direction discriminating unit 24 ( Step S32).
  When the analysis result from the image analysis unit 42 is an analysis result that the passenger passing through the doorway moves into the car (YES in step 33), the movement direction determination unit 24 moves in the movement direction. The determination unit 24 determines that the passenger who blocks the infrared rays from at least some of the sensors 2a to 2e is a passenger who has entered the car (step S34).
Moreover, the moving direction discrimination | determination part 24 is an analysis result that the analysis result from the image analysis part 42 is an analysis result that the passenger who passes the entrance / exit moves outside the car (NO in step 33), The movement direction determination unit 24 determines that the passenger who has blocked the infrared rays from at least a part of the sensors 2a to 2e is a passenger who has entered the car (step S35).
Then, the processes of steps S12 and S13 described in the first embodiment are performed.
  As described above, in the elevator according to the third embodiment, the moving direction of the passenger is determined using the detection result of the sensor and the image analysis. Therefore, since the movement direction of the passenger can be determined without using the two types of detection results of the sensor as in the first embodiment, the safety and convenience of the passenger can be improved as in the first embodiment. In addition, the number of sensors installed can be reduced.
(Fourth embodiment)
Next, a fourth embodiment will be described. In the present embodiment, every time a passenger passes through the doorway, it is determined whether the car room is full, and a full-passage operation is performed when the passenger is full.
FIG. 25 is a block diagram illustrating an example of a functional configuration of an elevator control device for an elevator according to the fourth embodiment.
As shown in FIG. 25, in the present embodiment, the elevator control device 20 further includes an occupied area calculation unit 51 and a fullness determination unit 52, as compared to the first embodiment.

Is calculated. In the present embodiment, the reference value of the occupied area per person corresponding to the type of passenger is stored in the storage device 26.
  For example, when the new determination result by the passenger type determination unit 23 is a determination result that two adults are on the car, the occupied area calculation unit 51 calculates the current occupied area calculated. Then, the occupied area obtained by adding the occupied areas corresponding to two adults is calculated as a new occupied area.
  Further, when the new determination result by the passenger type determination unit 23 is a determination result that one wheelchair user got out of the cab 1, the occupied area calculation unit 51 calculates the calculated current occupied area. On the other hand, an occupied area obtained by subtracting the occupied area corresponding to one wheelchair user is calculated as a new occupied area.
  Based on the occupied area calculated by the occupied area calculation unit 51 with respect to a predetermined floor area in the cab 1, the occupancy determination unit 52 determines whether or not the cab 1 is full so that no more passengers can ride. Is determined.
FIG. 26 is a flowchart illustrating an example of processing operations for passenger type, boarding / alighting direction determination, and fullness determination by an elevator according to the fourth embodiment.
First, determination of the type of passenger and determination of the moving direction are performed by the processing from steps S1 to S11 described in the first embodiment.
Passenger type determination unit 23 is a determination result before boarding or getting off when it is determined in step S10 that a passenger has entered the car or in step S11 that a passenger has got off the car. By adding or subtracting the number of passengers for each type in the car, the number of passengers in the car after getting on or getting off is determined for each type (step S12).
  When the car reaches the destination floor, the operation control unit 25 determines the door opening / closing speed of the car according to the type of the current number of passengers in the car, which is the discrimination result by the passenger type discrimination unit 23. Or the waiting time from the door opening to the door closing start is controlled (step S13).
  The occupied area calculation unit 51 determines the occupied area of passengers and luggage in the floor area in the cab 1 based on the current number of passengers in the car and the type of the passengers determined by the passenger type determining unit 23. The total number is calculated (step S41).
  The fullness determination unit 52 compares the predetermined floor area in the cab 1 with the occupation area calculated by the occupation area calculation unit 51 (step S42). Based on this comparison, the fullness determination unit 52 determines whether or not the ratio of the calculated value of the occupied area to the predetermined floor area in the cab 1 is equal to or greater than the predetermined ratio. It is determined whether or not it is full (step S43).
  When the ratio of the calculated value of the occupied area to the predetermined floor area in the cab 1 is less than the predetermined ratio and the occupancy determination unit 52 determines that the cab 1 is not full (NO in step S43) ), The process returns to step S1.
  In addition, when the ratio of the calculated value of the occupied area to the predetermined floor area in the car room 1 is equal to or greater than the predetermined ratio and the fullness determination unit 52 determines that the car room 1 is full (step The operation control unit 25 performs a full-pass operation that does not cause the car to respond even if the landing call registration on the intermediate floor up to the next destination floor is made (step S44).
  As described above, in the elevator according to the fourth embodiment, when the passenger passes through the doorway, the ratio of the calculated value of the occupied area to the predetermined floor area in the cab 1 is equal to or higher than the predetermined ratio. Even if the loading capacity of the car does not reach the upper limit, it is determined that the car is full and the full capacity driving is performed. Therefore, since it is possible not to perform an extra car response when full, operation efficiency is improved.
  In the present embodiment, the fullness determination unit 52 of the elevator control device 20 determines whether or not the ratio of the calculated value of the occupied area to the predetermined floor area in the car room 1 is equal to or higher than the predetermined ratio. Although it has been described that it is determined whether or not the interior of the room 1 is full, the present invention is not limited to this. For example, the calculated value of the occupied area of passengers and luggage in the car room 1 is calculated from the floor area value in the car room 1. Subtraction, and when the value after this subtraction is below a predetermined value or becomes zero, it may be determined that the interior of the car room 1 is full.
  In the present embodiment, as in the first embodiment, the case where the movement direction of the passenger is determined using the two types of detection results of the sensor 2 has been described, but the second or third embodiment will be described. Of course, this method can also be applied to the case where the moving direction of the passenger is determined by the above method.
  In addition, the operation control unit 25 of the elevator control device 20 in each embodiment waits until the door is closed when the destination floor registration button or the door opening / closing button is operated on the wheelchair user-specific operation panel in the car. Control such as extending
  However, if the passenger type determination unit 23 does not determine that there is a wheelchair user who has blocked the infrared rays from the sensor 2 within a predetermined time before this operation, the wheelchair user-specific operation panel is set as a healthy person. The normal door opening / closing control is performed without performing control such as extending the waiting time until the door closing starts.
  In addition, when the passenger type determination unit 23 determines that the current passenger in the car is only a child, the operation control unit 25 has some risk for this child when an adult or the like is on board. It is predicted that the number will increase in comparison with the manager of the building or the display device of the hall, notifying the building manager or outside the elevator car Call attention to users.
According to each of these embodiments, it is possible to provide an elevator that can perform operation control suitable for the type of passenger in the car.
