When it is detected in step B10 that the passenger has boarded the car, the hall button OFF failure determination unit 5 performs the operation of step B11. If it is not detected in step B10 that the passenger has boarded the car, the hall button OFF failure determination section 5 performs the operation of step B12.

In step B11, the hall button OFF failure determination unit 5 identifies that the hall call button OFF failure of the elevator occurs in the hall call button in the same direction as the car traveling direction of the detected floor. Then the flow ends.

In step B12, the hall button OFF failure determination unit 5 determines that the hall call button OFF failure of the elevator occurs in the hall button in the direction opposite to the running direction of the car on the detected floor. Then the flow ends.

In step B13, the elevator failure determination system determines whether or not the detected floor where it is determined that the hall button has an OFF failure is the lowest floor. If it is determined in step B13 that the detected floor is the lowest floor, the elevator failure determination system performs the operation of step B7. If the detected floor is not determined to be the lowest floor in step B13, that is, if the detected floor is the highest floor, the elevator failure determination system performs the operation of step B14.

In step B14, the hall button OFF failure determination unit 5 determines that the hall button OFF failure of the elevator occurs in the DOWN direction hall button of the detected floor. Then the flow ends.

Next, with reference to FIG. 5, operation of service to passengers by the elevator failure determination system when an elevator hall button OFF failure occurs on a specific floor will be described.
FIG. 5 is a flow chart for explaining an overview of the operation of the elevator failure determination system according to the first embodiment.

If it is not determined in step C1 that the detection floor and which side of the hall button, UP direction or DOWN direction, the OFF failure has occurred can not be identified, the flow ends.

At step C<b>2 , the person detection device 2 performs an operation of detecting a person near the hall call registration device 1 . When the person detection device 2 detects a person near the hall call registration device 1 in step C2, the elevator failure determination system performs the operation of step C3. If the person detection device 2 does not detect a person near the hall call registration device 1 in step C2, the flow ends.

In step C3, the elevator failure determination system determines whether or not a hall call has been registered even after a preset time has elapsed while a person has been detected at the detection floor. If the hall call is not registered at the detection floor even after the preset time has elapsed in step C3, the hall button OFF failure determination section 5 performs the operation of step C4. If a hall call is registered at the detected floor before the preset time elapses in step C3, the hall button OFF failure determination unit 5 performs the operation of step C8.

At step C4, the hall button OFF failure determination unit 5 determines that the hall button has an OFF failure at the detected floor. The call automatic registration unit 7 automatically registers the hall call at the detected floor. The hall call registration device 1 turns on the hall registration lamp. After that, the elevator failure determination system performs the operation of step C5.

In step C5, the elevator failure determination system determines whether the detected floor is an intermediate floor. If the detected floor is determined to be an intermediate floor in step C5, the elevator failure determination system performs the operation of step C6. If the detected floor is not determined to be an intermediate floor in step C5, the flow ends.

At step C6, the car reaches the detected floor. A boarding detection device 4 detects that a passenger has boarded the car.

According to the first embodiment described above, the elevator failure determination system determines that the hall call button is out of order by detecting a person near the hall. Therefore, even if the hall call button itself is physically out of order, the failure can be determined.

Further, the elevator failure determination system can determine a physical failure of the hall call button by software.

Further, when it is determined that the hall call button is out of order, the hall call registration device 1 automatically registers the hall call to the hall where the hall call button is judged to be out of order. Therefore, even if the hall call button is out of order, the service to the hall can be continued.

Further, the platform call registration device 1 notifies the outside that the platform call has been automatically registered. Therefore, it is possible to inform the person near the hall that the hall call has been registered.

In addition, the hall button OFF failure determination unit 5 allocates a car to a hall where it is determined that the hall call button is out of order, and when an upward car call is registered in the car after the car is dispatched, an upward direction of the hall is selected. is determined to be out of order. Therefore, the direction of the malfunctioning hall call button can be specified.

In addition, the hall button OFF failure determination unit 5 allocates a car to a hall where it is determined that the hall call button is out of order, and when a downward car call is registered in the car after the car is dispatched, is determined to be out of order. Therefore, the direction of the malfunctioning hall call button can be identified.

Further, when the hall where it is determined that the hall call button is out of order is located on the lowest floor, the hall button OFF failure determination unit 5 judges that the up hall call button is out of order. Therefore, the direction of the malfunctioning hall call button can be specified.

Further, when the hall where it is determined that the hall call button is out of order is located on the top floor, the hall button OFF failure determination unit 5 judges that the down hall call button is out of order. Therefore, the direction of the malfunctioning hall call button can be specified.

Further, when the hall where it is determined that the hall call button is out of order is located on an intermediate floor and there is a car running in the direction passing through the hall, the hall call registration device 1 registers the vehicle in the same direction as the car running direction. The hall call is automatically registered, and when it is detected that a passenger has boarded the car at the hall, the hall call button in the same direction as the traveling direction of the car is out of order. If it is not detected that a passenger has boarded the car at the hall, it is determined that the hall call button in the direction opposite to the traveling direction of the car is out of order. Therefore, the direction of the malfunctioning hall call button can be specified.

Further, when a hall call is registered from the hall call button determined to be out of order, the hall button OFF failure determination unit 5 cancels the failure determination. Therefore, when the failure is resolved, normal operation can be resumed.

The elevator failure determination system also determines whether the car is certain to stop at the particular floor or whether the car doors are in service when a person is detected at the landing. For this reason, it is already confirmed that the car will stop at the relevant hall, so if the hall call is not registered, it is possible not to judge that there is a failure. As a result, erroneous fault detection can be prevented.

Instead of the person detection device 2, a camera provided at the hall may detect the motion of a person near the hall. Even in this case, the direction of the faulty hall call button can be identified.

As described above, the elevator failure determination system of the present disclosure can be used for elevators.
