Description

  The present invention relates to an elevator operation system for transporting passengers to each floor of a building.

  The elevator hall on each floor of the building is provided with a call button for calling a car to the elevator hall. For example, a passenger who wants to move from the first floor to the fourth floor presses a call button on the first floor to register a car call and waits for the arrival of the car. Car call registration is displayed when the call button is lit. Then, after the car arrives at the first floor and stops, the passenger gets into the car and presses the destination floor button in the car to register the destination floor. In response to this registration, the car moves toward the destination floor. Passengers get off the car after it arrives at the destination floor and stops. The car then moves to the next destination floor or the nearest elevator hall where the car call registration is.

  By the way, many passengers rush to the elevator hall on the floor with the building, and the elevator hall may be crowded with the passengers. In this case, one of the passengers in the elevator hall presses the call button to register the car call and waits for the arrival of the car. And after the car arrives at the elevator hall, passengers get into the car. At this time, if the elevator hall is congested, everyone cannot ride in the car and passengers remain in the elevator hall. Then, after the car moves and the call button turns off, the passengers remaining in the elevator hall press the call button again to register the car call.

  When the preceding car moves to a predetermined floor, passengers in the car get off and the car becomes empty, the car moves toward the elevator hall where the car call is registered. For example, it moves from the fourth floor toward the crowded first floor. At this time, if a car call is registered on a floor other than the crowded first floor, for example, the third floor, the car is temporarily on the third floor on the way to the first floor even though the first floor is crowded. Stop and then move to the first floor. For this reason, the waiting time on the first floor is prolonged, and the elevator hall on the first floor becomes increasingly crowded, and passengers waiting for the car on the first floor become annoyed.

  By the way, in JP-A-2006-151533, a sensor for detecting the number of passengers waiting for a car in the elevator hall is provided in the elevator hall of each floor, and a sensor for detecting the number of passengers in the car is provided in the car. It is disclosed that the operation of the elevator is controlled according to the number of people waiting in the elevator hall or the number of people in the car.

JP 2006-151533 A

  In Patent Document 1, for example, when a car moves from the fourth floor to the third floor, there is a car call registration on the third floor, but when passengers in the car do not plan to get off on the third floor, the elevator on the third floor The sensor of the hall detects the presence or absence of passengers in the elevator hall, and if there is no passenger, even if a car call is registered, it will pass through the elevator hall on the third floor without stopping so as to prevent useless stops I have to.

  Also, for example, when a car moves from the 4th floor to the 3rd floor, there is a car call registration on the 3rd floor, there are passengers who reach the capacity in the car, and there are no plans for that passenger to get off on the 3rd floor Sometimes, the number of passengers in the car is detected by a sensor to determine that the number of passengers has been reached, and even if there is a car call registration on the 3rd floor, it stops at the 3rd floor elevator hall It is intended to prevent useless stops by passing without.

  As described above, in Cited Document 1, the number of people waiting in the elevator hall or the number of people in the car is detected so as to prevent an unnecessary stop of the elevator so as to operate efficiently. When passengers rush into the hall and become crowded, elevators cannot be operated to eliminate the crowd.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an elevator operation system that can efficiently operate an elevator so as to quickly eliminate the congestion when a passenger rushes into the elevator hall on a certain floor and becomes crowded. It is said.

The block diagram which shows the structure of the control circuit of the elevator. The flowchart which shows the flow of operation | movement of the elevator.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 shows the overall configuration of the elevator. A hoistway 1 is provided in the building, and a car 2 is suspended in the hoistway 1 via a rope 3. A machine room 4 is provided in the upper part of the hoistway 1, and a hoisting machine 5 as a driving means for driving the car 2 and a control panel 6 as a control means for controlling the hoisting machine 5 are provided in the machine room 4. Is provided.

Entrance halls 10 are provided in the elevator halls on each floor of the building, and operation panels 11 are provided on the sides of these entrances and exits 10, respectively. As shown in FIG. 2, the operation panel 11 is provided with an upward call button 11a and a downward call button 11b as car calling means. The lowermost operation panel 11 is provided with only the upward call button 11a, and the uppermost operation panel 11 is provided with only the lower call button 11b.
In addition, in the elevator hall on each floor, a human sensor 13 is provided as a human detection means. As shown in FIG. 2, for example, three human sensors 13 are arranged at the upper part of the entrance 10 so as to be arranged side by side at a predetermined interval. These human sensors 13 detect the presence or absence of passengers waiting for the arrival of the car 2 in the elevator hall. 2 is a door device that opens and closes the entrance 10.

  As shown in FIG. 3, each call button 11a, 11b and each human sensor 13 are connected to the control panel 6, and a signal when each call button 11a, 11b is operated is sent to the control panel 6, The car call is registered by the signal, and the car 2 is controlled to move to the elevator hall in which the call buttons 11a and 11b are operated during normal operation. When the call buttons 11a and 11b are operated, the call buttons 11a and 11b are turned on to display registration of the car call and are turned off when the car 2 arrives.

  The control panel 6 has timer means 15, and when the call buttons 11 a and 11 b are turned off from the lighting state by the timer means 15 and the call buttons 11 a and 11 b are pressed again and turned on, the control panel 6 is turned on from the turn-off. The time until is counted. The signal from the human sensor 13 is sent to the control panel 6, and the control panel 6 determines the presence or absence of passengers in the elevator hall based on the signal.

  Next, the operation will be described with reference to the flowchart of FIG.

  Now, for example, in an elevator hall on the first floor, it is assumed that passengers scheduled to go upstairs are flooded and crowded. One of the passengers presses the call button 11a (S1). In response to this, the car call is registered, the call button 11a is turned on (S2), and the car 2 moves toward the elevator hall on the first floor under the control of the control panel 6.

  When the car 2 arrives at the elevator hall on the first floor and stops (S3), the call button 11a is turned off (S4). Passengers in the elevator hall on the first floor get on the stopped car 2 (S5). At this time, since there are a large number of passengers in the elevator hall on the first floor, all of them cannot ride and a part remains in the elevator hall. The passenger in the car 2 designates a target destination floor, and the car 2 moves toward the destination floor in response to this (S6).

On the other hand, the passenger remaining in the elevator hall presses the call button 11a immediately after the car 2 moves (S7). As a result, the car call is registered again, and the call button 11a of the elevator hall on the first floor is turned on (S8).
At this time, the elapsed time T from the turn-off of the call button 11a to the lighting is counted by the timer means 15 of the control panel 6, and it is determined whether the time T is within a predetermined time. For example, the control panel 6 determines whether the time is within 30 seconds or exceeds 30 seconds (S9). Further, based on the detection by the human sensor 13, the presence or absence of passengers in the elevator hall on the first floor is determined by the control panel 6 (S10).

  Then, in S9, it is determined that the time T is within 30 seconds, and when it is determined that there is a passenger in S10, the car 2 arrives at the destination floor, the passenger gets off, and the car 2 is empty. The car 2 is controlled to move to the crowded elevator hall on the first floor with priority over other floors (priority operation: S11). Then, passengers in the elevator hall on the first floor get on the car 2 and move to the target destination floor (S12). At this time, when the passengers cannot complete the car 2 and some passengers remain in the elevator hall, the steps of S7 to S11 are repeated.

  When it is determined in S9 that the time T is longer than 30 seconds, there is no passenger in the elevator hall on the first floor and the call button 11a is not pressed, that is, the congestion has already been eliminated. When the time T is longer than 30 seconds, the car 2 is normally operated under the control of the control panel 6 (S13). When there is a car call in an elevator hall other than the first floor, The car 2 is controlled so as to move.

  Further, in S9, it is determined that the time T is within 30 seconds, and in the next S10, based on the detection by the human sensor 13, there is no passenger in the determination of the presence or absence of passengers in the elevator hall on the first floor. When the determination is made, the car 2 is normally operated (S13), and when the car is called in an elevator hall other than the first floor, the car 2 is controlled to move toward the elevator hall.

  In this way, when the car 2 arrives at the crowded 1st floor elevator hall and a certain number of passengers get on the car 2, but there are passengers that remain unoccupied, the car 2 moves to the destination floor. After being empty, the car 2 moves to the elevator hall on the first floor in preference to the other floors. For this reason, the waiting time in the elevator hall on the first floor can be shortened to quickly eliminate congestion in the elevator hall, and the irritation of passengers waiting in the elevator hall on the first floor can be eliminated.

In S9, even if it is determined that the time T is within 30 seconds, it is determined that there is no passenger in the next determination of the presence of passengers in S10. 11a is pushed, but the passenger in the elevator hall on the first floor leaves the elevator hall by using a staircase and the passenger is no longer in the elevator hall on the first floor. Even in such a case, if the priority operation in which the car 2 moves with priority over the elevator hall on the first floor is executed, the movement of the car 2 is wasted.
Therefore, in this embodiment, when it is determined in S9 that the time T is within 30 seconds, in the next S10, passengers remaining in the elevator hall on the first floor are detected based on the detection by the human sensor 13. When it is determined that there is no car, the car 2 is moved in a normal operation, and when there is a car call in an elevator hall other than the first floor, the car 2 is controlled to move toward the elevator hall. As a result, it is possible to prevent a wasteful operation in which the car 2 moves preferentially to the first floor where there are no passengers, thereby achieving an efficient operation without waste.

  The above description is an example of eliminating congestion in the elevator hall on the first floor. However, when congestion occurs in the elevator hall on other floors, the congestion is eliminated by the same control.
