Description

  The present invention relates to an elevator apparatus that avoids a collision between passengers when getting on and off.

  Normally, elevator passengers know that there are people who get off or get in for the first time when the elevator door opens. For this reason, if the person getting out of the car and the person getting in are in a hurry, they often collide.

In order to avoid a collision between passengers, Japanese Patent Laid-Open No. 5-43153 (Patent Document 1) and Japanese Patent Laid-Open No. 2001-16353 (Patent Document 2) first detect a landing call or a car call, or a car. Passengers are detected to determine if there are people getting out of or getting into the car. And before landing (before opening the door), passenger information on the arrival floor is notified to passengers in the car and waiting passengers at the landing using voices, symbols and character displays, so that the flow of people is smooth. To avoid collisions.
JP-A-5-43153 JP 2001-16353 A

  However, in the above-mentioned conventional example, passenger information on the arrival floor is notified by voice, symbol or character display before landing (before opening the door). It is not controlled in conjunction with. For this reason, notification may start immediately before the door is opened, and in this case, sufficient notification cannot be made before the door is opened. Thus, when the notification time is short, the passenger may get on and off without noticing the notification, and the passengers may collide with each other. Moreover, it is difficult for a disabled person or an elderly person who is incapacitated even when alerted to take a collision avoiding operation in a short time, and may collide with a passenger getting out of the car. In the future, because the number of physically disabled people and elderly people will be mixed and will use the elevator, it is expected that many situations as described above will occur.

  SUMMARY OF THE INVENTION In view of the above circumstances, an object of the present invention is to provide an elevator device that can prevent passengers from colliding with each other when getting on and off an elevator car.

  In order to achieve the above object, the present invention provides a waiting passenger detection means for detecting a waiting passenger near a landing door, a passenger detection means for detecting a passenger in a car, a waiting person in a hall, and a passenger in a car. Based on the notification means for performing voice guidance, the registration status of hall calls and car calls on each floor, the detection results of the waiting passenger detection means and passenger detection means, and the voice guidance status of the notification means, And a control means for controlling.

  According to the elevator apparatus according to the present invention, it is possible to prevent the passengers from colliding with each other when the elevator car gets on and off.

This elevator control device 12 is responsible for some of the control items for various operations and operations such as elevator up / down, stop, door open / close, voice / display guidance, etc. The hall call registration circuit 13, the passenger detection circuit 14, the car call registration circuit 15, the waiting customer detection circuit 16, and the determination circuit 17 are provided.

  The hall call registration circuit 13 receives destination floor data sent when a passenger in the elevator car 1 registers a destination floor by pressing a hall call button provided in the hall call operation device 2. The hall call registration circuit 13 holds the received destination floor data until the elevator car 1 reaches the destination floor and the call is deleted, and supplies the data to the determination circuit 17.

  The passenger detection circuit 14 receives passenger detection data output when a passenger in the elevator car 1 is detected by the passenger detection device 5. When the passenger detection circuit 15 receives the passenger detection data, the passenger detection circuit 15 supplies this data to the determination circuit 17.

  The car call registration circuit 15 receives car call data that is output when an up call or down call is instructed by pressing a button of the car call operating device 9 in the hall. When the car call registration circuit 15 receives the car call data, the car call registration circuit 15 holds the data until the landing door 6 is opened and supplies the car call data to the determination circuit 17.

  The waiting customer detection circuit 16 receives waiting customer detection data output when the waiting customer detection device 8 detects a waiting customer in the hall. Upon receiving the waiting customer detection data, the waiting customer detection circuit 16 supplies the data to the determination circuit 17.

  A hall call registration circuit 13, a passenger detection circuit 14, a car call registration circuit 15 and a waiting customer detection circuit 16 are connected to the determination circuit 17, and data registered or detected from these circuits is supplied. Then, in the elevator car 1 based on the notification execution signal received from the announcer output circuit 18 and the waiting passenger detection data from the waiting passenger detection circuit 16 when the passenger hall voice guidance performs voice notification of the passenger information. And it is determined whether a message is supplied to the car voice guidance device 3, the hall hall voice guidance device 10, the car display device 4, and the hall hall display device 11, and whether the door is automatically opened.

  The announcement output circuit 18 constitutes notification means, selects data corresponding to the traveling direction of the elevator car 1 from preset announcement data, and selects the selected announcement data from the in-car voice guidance device 3. And output to the hall hall voice guidance device 10. As for the content of the guide announcement from the hall hall voice guidance device 10, in the case of the up direction in accordance with the traveling direction of the elevator car 1, for example, “An upward elevator will come. Please open widely. " In the case of the down direction, an announcement such as “An elevator in the downward direction will come. There are people getting off, please open the front of the door.” Is given to the waiting passengers in the hall.

  The timing setting circuit 19 sets the timing for supplying the announcement signal to the elevator car 1 and the car voice guidance device 3, the hall hall voice guidance device 10, the car display device 4, and the hall hall display device 11.

  Next, the operation of the first embodiment will be described with reference to the flowchart of FIG. The flowchart shown in FIG. 2 shows the door opening control, and prevents the landing door from being automatically opened even if the user lands on the floor until the voice notification ends.

  When the elevator stops at the destination floor during the operation of the elevator, first, the determination circuit 17 determines whether or not a voice is being output by the hall hall voice guidance device 10 (step S1). If no sound is output, it means that there is no waiting customer, and the door is automatically opened after landing (step S4).

  If the sound is output, it is determined whether the waiting customer is detected by the waiting customer detection circuit 16 (step S2). When the waiting customer is not detected, the waiting customer is retracted from the front of the door, so that the door is automatically opened after landing (step S4).

  If there is a waiting customer, it is determined whether or not the voice output has ended (step S3). When the voice output is completed, it is assumed that the waiting customer who has confirmed the voice guidance can evacuate from the front of the door, and automatically opens after landing (step S4).

  If the voice output has not ended, the process returns to step S2 without automatically opening the door even when the user lands, and the detection of the waiting customer and the status of the voice output are confirmed (step S5).

  As described above, according to the first embodiment, the landing door is not automatically opened even when the user gets on the floor until the voice notification is finished, so that it is possible to avoid collision between passengers. it can.

<Second Embodiment>
FIG. 3 is a flowchart showing the operation of the second embodiment of the present invention.

  In the second embodiment, as long as a waiting customer is detected in front of the landing door 6, the landing door 6 is not automatically opened even if a car arrives on the floor. .

  That is, when the elevator stops, the determination circuit 17 determines whether or not sound is being output by the hall hall audio guidance device 10 (step S11). If no sound is output, the car is automatically opened after landing (step S14).

  On the other hand, when the sound is output, it is determined whether or not a waiting customer is detected by the waiting customer detection device 8 (step S12). If no waiting customer has been detected, it means that there is no waiting customer in front of the door, so that the repetition of voice / display output is stopped and the door is automatically opened after landing (steps S13 and S14).

  When a waiting customer is detected, voice / display output is repeated (step S15), and the door does not automatically open even after landing (step S16). The waiting customers are evacuated until no one is left (step S12).

  As described above, according to the second embodiment, as long as a waiting customer is detected in front of the landing door 6, the landing door 6 is not automatically opened even when a car arrives on the floor. It is possible to avoid the collision between passengers.

<Third Embodiment>
FIG. 4 is a flowchart showing the operation of the third embodiment of the present invention.

  In the third embodiment, even if it is detected that there is a waiting customer in front of the landing door 6, it is a certain time after landing (for example, about 30 to 60 seconds in which voice notification can be repeated several times is desirable). It is designed to automatically open the door when the time has passed.

  That is, when the elevator stops, the determination circuit 17 determines whether or not a sound is being output by the hall hall voice guidance device 10 (step S21). If no sound is output, it means that there is no waiting customer in front of the door, so the door is automatically opened after landing (step S24).

  When the sound is output, it is determined whether or not a waiting customer is detected (step S22). When no waiting customer is detected, it means that there is no waiting customer in front of the door. Therefore, it is assumed that safety has been confirmed, and the repetition of voice / display output is stopped (step S23), and the door is automatically opened after landing. (Step S24).

  If it is determined that there is a waiting customer, it is determined whether or not a certain time has elapsed since arrival (step S25). When the certain time has elapsed, sufficient waiting time is given to the waiting customer. Therefore, the repetition of the voice / display output is stopped (step S23), and the door is automatically opened after landing (step S24).

  When the predetermined time has not elapsed, the voice / display output is repeated (step S26), and the door is not automatically opened even after landing (step S27). The evacuation of the waiting customer is urged until they are absent (step S22).

  Thus, according to the third embodiment, even if it is detected that there is a waiting customer in front of the landing door, the automatic door is not opened until a certain time has elapsed after landing. It is possible to avoid collision between each other.

<Fourth Embodiment>
FIG. 5 is a flowchart showing the operation of the fourth embodiment of the present invention.

  In the fourth embodiment, when the door is opened in a state where it is detected that there is a waiting customer in front of the landing door 6, a voice notification that “slowly opens” is made before the landing door 6 is opened. The door opens at a lower speed than usual.

  That is, when the elevator stops, the determination circuit 17 determines whether or not a sound is being output by the hall hall voice guidance device 10 (step S31). If no sound is output, the door is automatically opened after landing (step S35).

  When the sound is output, it is determined whether or not a waiting customer is detected (step S32). When no waiting customer is detected, it means that there is no waiting customer in front of the door, so the repetition of voice output is stopped (step S34), and the door is automatically opened after landing (step S35).

  When a waiting customer is detected, it is determined whether or not a certain time has elapsed since arrival (step S33), and when the certain time has elapsed, a voice notification that “slowly opens” is performed. (Step S36), after landing, the door is automatically opened at a low speed (Step S37).

  If the predetermined time has not elapsed, the sound output is repeated (step S38), and even if the user gets on the floor, the door is not automatically opened (step S39), and the process returns to step S32.

  As described above, according to the fourth embodiment, waiting passengers near the landing are detected and passengers get on and off by providing time to perform alerting and avoidance operations before opening the door until there are no waiting passengers near the landing door. Therefore, the collision between passengers can be avoided in advance.

  In addition, waiting passengers near the landing doors are detected, and even if there are passengers near the landing doors, they will not be opened until a certain time has elapsed after landing. Time to perform can be provided reliably and the collision of passengers can be avoided.

  Furthermore, by detecting waiting passengers near the landing doors and guiding the passengers to “slowly open”, the doors will be opened to sufficiently alert the passengers and avoid collisions between passengers. be able to.
