BEST MODE FOR CARRYING OUT THE INVENTION

Embodiment 1 FIG. FIG. 1 is a configuration diagram of an elevator power outage control operation device according to an embodiment of the present invention. FIG. 2 is a diagram showing a configuration of a control system for performing a power failure control operation in accordance with the presence or absence of a passenger in a car in the apparatus shown in FIG.
In the figure, 1-4 are baskets, 5-8 are each of these baskets 1
4 is a car control device, 9 is a group control device for group-controlling the car control devices 5 to 8, and 10 is a landing on each floor.

Reference numeral 11 denotes a passenger detector, which comprises, for example, a carbon dioxide detector for detecting carbon dioxide (CO ₂ ) contained in human breath, and is attached to each of the baskets 1 to 4. A passenger detector control device 12 controls the carbon dioxide detector 11, which is a passenger detector, and outputs a signal when detecting a certain amount or more of CO ₂ . Reference numeral 13 denotes a car selection calculation device that selects a car to be operated based on a signal transmitted from the control device 12 of each car.

FIG. 3 is a flow chart showing the operation of the driving device shown in FIGS. This operation is also basically controlled entirely by a computer provided in the group control device 9 and operating according to a program.

The operation of the present invention will be described below. When a power failure occurs (step S1), each of the cages 1 to 4 stops at that location. Then, electric power of an auxiliary power supply (not shown) is supplied by private power generation (step S2). At this time,
When an automatic power failure operation switch (not shown) of the group control device 9 is turned on (step S3), a first predetermined power failure operation is performed.
An operation command is generated for the car, for example, car 1 (step S5). The car 1 is controlled and operated according to the operation command.
The vehicle is stopped at the nearest floor (step S6).

Hereinafter, similarly to the first basket, the control is sequentially performed in a predetermined order (for example, the second basket (cage 2) → the third basket (cage 3) → the fourth basket (cage 4)). The driving returns the car to the nearest floor (step S7). If the automatic power failure operation switch is not turned on in step S3, it is determined that there is another abnormality, and the car is not controlled for operation, and the stopped state at the time of power failure is continued (step S4).

The above operation is the same as the conventional one,
According to the present invention, between steps S3 and S5, the detectors 11 mounted in the cages 1 to 4, respectively.
It is determined whether or not has operated (step S9). If it is operating, it is determined whether or not the detected amount (here, the amount of CO ₂ ) is equal to or greater than a specified value (step S10). If there are a plurality of cages having the specified value or more, the operation order of the cages having the specified values or more is calculated (step S11). In this operation order, for example, baskets having a predetermined value or more may be simply determined in the order of arrangement, or the detected amount may be included in one of the factors determining the order.

When an operation command is issued to the first selected car in accordance with the result of the above-described operation order calculation (step S12), the first selected car is moved to the landing 10 on the nearest floor by the control operation. Stopped (step S
13). And if there are multiple baskets that are more than the specified value,
The second selected basket is operated in the same manner (step S1).
4, S15), when all the operations of the passenger detection car are completed (step S16), an operation command is issued to the car in which the passenger is not detected,
The control operation to the nearest floor is performed sequentially in the same manner as in the related art (steps S17 and S18).

Embodiment 2 In the above embodiment, the passenger detector 11 uses a carbon dioxide detector that detects CO ₂ contained in human breath, but uses a heat detector that detects heat radiated from the passenger's body. Can achieve the same effect.

Embodiment 3 Further, a weighing device that is legally required to be attached to the passenger elevator as the passenger detector 11 may be used to detect the weight of the entire car including the passenger, and the same operation can be performed.
