Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator operating apparatus, and more particularly to an elevator operating apparatus that utilizes a privately-generated power source during a power outage and performs an elevator-originated control operation, which is an elevator rescue operation during a power outage. .

[0002]

2. Description of the Related Art The current self-starting control operation in an elevator of this type is described in the Erekyo standard JEAS-413, and is intended for the early rescue of passengers trapped in a car due to a power failure and the minimum building function. The purpose is to maintain. Specific operations include a return operation for rescue of passengers in the car and a continuous operation for maintaining functions in the building when the private power source is established.

In the current elevator, the shift to the self-starting control operation depends only on the customer power failure detection contact, as described in the Erekyo standard JEAS-413. That is, when the customer power supply power failure detection contact detects a power failure, the operation shifts to the control operation at the time of in-house power generation without judgment of in-house power generation or power purchase.

[0004]

As described above, in the current elevator, since the transition to the self-start control operation is performed only by relying on the customer power failure detection contact, For example, if the customer power failure detection circuit is accidentally or accidentally cut off by mistake, the customer power failure detection contact with the elevator will be in a power failure, and the elevator will not actually be a power failure, but power will be purchased. There is a problem that it will be used to carry out ATC control at home. When such a situation occurs, even if it is not a power failure, it will be a big problem that the elevator which is the transportation means in the vertical direction of the building is stopped by carrying out the control operation at the time of in-house departure.

The present invention has been made in order to solve such a problem, and by providing a power failure detecting means on the elevator side, and the power failure detecting means detects a power failure, the customer power failure can be detected. An object of the present invention is to obtain an elevator control device that can prevent unnecessary self-starting control operation even when a malfunction occurs.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiment 1. FIG. 1 is a block diagram showing a configuration of an elevator operating device according to a first embodiment of the present invention. In the figure, 1 is a customer power supply power failure detection contact, which is connected to a customer power supply 2 described later,
It is for detecting whether or not the customer-supplied power supply 2 has a power failure.
Reference numeral 2 is a customer-supplied power supply (power purchase), which is a power supply that the customer purchases from a power company. Reference numeral 3 denotes an in-house power source, which is a power source generated by the in-house power generator 2 when the in-house power source 2 fails to operate the in-house generator. Reference numeral 4 denotes an elevator power failure detection means, which is provided in the elevator and detects the power failure of the customer-supplied power supply 2 on the elevator side. The elevator power failure detection means 4 uses, for example, an elevator control (micro) computer, and is set so that when the private power source 3 is established, the elevator is energized and the elevator control computer starts up. The power-on detection, which operates when the computer starts up, is used to detect a power failure. Reference numeral 5 is a customer power supply power failure detection malfunction output means, which detects that the customer power supply power failure detection contact 1 has malfunctioned and outputs it to the outside. Reference numeral 6 denotes an elevator operating means, which operates the elevator by obtaining electric power from the customer-supplied power supply 2 or the private power supply 3.

FIG. 2 shows an example of a processing flow of the elevator operating apparatus of FIG. The process of self-start control operation when a power failure occurs will be described with reference to FIG. It should be noted that this processing flow is executed in a predetermined cycle after being started when the elevator control computer is started up.

It is assumed that a power failure occurs and the private power source 3 is established while the power is being supplied from the customer's power source 2 and the normal operation is performed. When the private power source 3 is established, the elevator is energized by the power from the private power source 3, and the elevator control computer starts up. When the elevator control computer starts up, in step S1,
A determination process of "is the elevator control computer start-up flag OFF?" Is performed. At this point, the flag is still OFF, but since the privately-generated power source 3 is on, the process proceeds to step S2 and step S2.
In, the elevator control computer start-up flag is set, and then in step S3,
The elevator blackout detection flag is set (ie,
Transition those flags from OFF to ON).

In the subsequent processing of the execution cycle which is carried out in the predetermined cycle, "whether the computer rising flag for elevator control is OFF" in step S1.
Since the flag is ON, the process proceeds to the determination process of “whether one minute or more has elapsed after setting the elevator control computer startup flag” in step S4, and the determination result is “NO (one minute or more has not elapsed. ) ”, The process proceeds to step S7,“ Is the customer power supply power failure detection contact detected a power failure? ”. Although “1 minute or more” is described as an example here, the time “1 minute” is not limited to this, and may be any value as long as it is a predetermined time. Is good.

Since a power failure has occurred and the customer power supply power failure detection contact 1 has detected a power failure, the result of the determination in step S7 is "Y".
ES (power failure detection) ", the process proceeds to step S8" Elevator power failure detection flag is ON "and the elevator power failure detection flag is ON, so step S8
Proceeding to 9, the elevator control computer commands the control operation at private departure.

On the other hand, when one minute has passed after the establishment of the private power source,
In the determination process of "whether one minute or more has elapsed after setting the elevator control computer startup flag" in step S4, the determination result is "YES (one minute or more has elapsed)",
In step S5 and step S6, the elevator control computer rising flag and the elevator power failure detection flag are reset (that is, those flags are returned from ON to OFF).

Next, by mistake, not the power failure but the customer-supplied power supply 2
The following describes an example of the processing in the case where the normal operation is continued when the power of the customer power failure detection contact 1 is cut off when the power supply is normal. Since the elevator control computer start-up flag is ON in the determination processing of "whether the elevator control computer start-up flag is OFF" in step S1, "1 minute or more has elapsed after setting the elevator control computer start-up flag". Go to the determination process of. Since the determination result is "NO (one minute or more has not elapsed)", the process proceeds to step S7, "Is the customer power supply power failure detection contact detected a power failure?" Customer power supply 2
Is actually normal, but in this case,
Since the power of the customer power failure detection contact 1 is cut off,
The determination result in step S7 is "YES (power failure detection)", and the "elevator power failure detection flag is 0" in step S8.
However, since the detection result of the elevator power failure detection means 4 is "no power failure", the elevator power failure detection flag is OFF, and it is clear that the customer power failure detection contact 1 has malfunctioned. In step S10, the fact that the customer power failure detection contact 1 is malfunctioning is output to the outside of the elevator, and as a matter of course, in step S11, the normal operation is continued without shifting to the self-start control operation. .

As described above, in the conventional self-starting control operation, since the elevator itself does not detect the power failure, it is carried out based on the power failure detection information supplied by the customer.
If the power failure detection information supplied by the customer is falsely detected for some reason,
There was a problem that the elevator erroneously operated at home control and the elevator could not be used, but in the present invention, since the power failure is also detected on the elevator side, the power failure can be reliably grasped and supplied to the customer by any chance. Even when the power failure detection is erroneously detected, it is possible to prevent the unnecessary self-start control operation from being performed. Further, in the present invention, since the elevator power failure detection means is configured by diverting the existing elevator control computer, it does not require a special device and is an inexpensive method, and a power failure on the elevator side. Detection can be realized.

In the above description of the embodiment, an example in which the power failure related information supplied from the customer is detected only by the customer power failure detection, and the elevator side detects the power failure with the control computer standing up However, the same effect can be obtained even in the case where there is a private power supply establishment contact that detects that the private power supply has been established.

Further, although the above-described embodiment has been described in the case of one elevator, the same effect can be obtained in the case of a group management type elevator.

Further, in the case of a group management type elevator,
Elevator power failure detection flags are sent from each unit control panel to the group management, and on the condition that the elevator power failure detection flags of all units in the bank have detected a power failure on the group management side, control operation at private departure is performed You can also do so.

When the elevator power failure detection flag does not operate and the customer-supplied power failure detection information operates,
Customer-supplied outage detection information Malfunction information can be easily notified to the outside of the elevator.
