Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in an elevator operating device when a call processing device is out of order.

Elevators normally operate automatically, stopping only at floors with hall calls or car calls, and passing through floors without such calls.

If the hall call button or car call button becomes unable to detect all floors for some reason, the elevator control device will not know which floor the passenger is waiting for or which floor the passenger wants to go to, and automatic operation in the above sense will occur. becomes impossible. Traditionally, in such cases,
A minimum level of passenger service is ensured by stopping operation at each floor, but stopping at each floor increases the load on the electric motor that drives the elevator, and depending on the type of motor, the amount of heat generated may increase. is too large and may burn out.

Attempts have also been made to improve these drawbacks. For example, when performing stop operation on each floor, it may be possible to prevent departure from a predetermined floor (for example, the lower end floor) for the specified time required for the heat generation of the motor to subside, or to limit the minimum stop time for each floor. Sometimes I do something. However, in both cases, the waiting time for passengers at the terminals is extremely long, and they are highly unpopular. Of course, if a motor with a larger capacity is used, it will generate less heat, but the cost will increase.

The present invention solves the above-mentioned drawbacks, and aims to provide an elevator failure operation device that suppresses heat generation of the electric motor and also prevents the waiting time of passengers waiting at the hall from becoming excessively long.

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

In the figure, +1, -1, +2, -2 are each a separate DC power supply, 1 is an emergency detection relay consisting of a power supply monitoring relay, 1a is its normally closed contact, and 11 to 15 are connected to the landings on the 1st to 5th floors, respectively. Up call button provided,
21 to 25 are car position relay contacts that open when the car arrives at the 1st to 5th floors, respectively; 31 to 35 are 1
~ 31a ~ 35a at the up call registration relay on the 5th floor
41 is the automatic call registration floor selection auxiliary relay, 41a and 41b are the normally open contacts, 42
are automatic call registration floor selection relays, 42a, 42b
is the normally closed device, 42c and 42d are the normally open contacts, 43a and 43b are the first floor arrival relay contacts that close when the car arrives on the first floor, 43c are the first floor arrival relay contacts that also open, and 44a and 44b are the first floor arrival relay contacts. Descending relay contact that closes when the car is descending, 4
Reference numerals 5a and 45b are ascending direction relay contacts which similarly close during ascending, and 51 to 55 are automatic upward call registration relays which, when energized, register upward calls for the 1st to 5th floors, respectively.

Next, the operation of this embodiment will be explained.

Now, when the up call button 11 on the first floor is pressed,
When the car is not on the first floor, the relay 31 is energized and held by the contact 31a to register the first floor up call. Thereafter, when the car reaches the first floor, the car position contact 21 is opened, the relay 31 is deenergized, and the first floor up call is canceled. The same applies to the up call registration relays 32 to 35 on other floors.

Now, for some reason, the power supply + in Figure 1
1, -1 are disconnected, relay 1 is deenergized;
Contact 1a is closed. On the other hand, even if any of the buttons 11 to 14 is pressed, the relays 31 to 35 are not energized, and a hall call cannot be registered.

At this time, it is assumed that power supplies +2 and -2 in FIG. 2 are alive, but both relays 41 and 42 are not energized. Since contacts 1a and 42b are both closed, relays 51, 53, and 55 are energized. This means that the up calls for the 1st, 3rd and 5th floors have been registered, so the cage will service each call.
(The first floor is always registered whenever the power supply +1 or -1 is cut off.) Within that time, the car will arrive at the first floor while descending, and even if there is a moment when it has no direction, it will now have an upward direction. shall be. First, the car is 1
When arriving at the floor, contacts 43a and 44a close,
Since the contact 42a is generally closed, the relay 41
is energized and self-retains by closing contact 41a. Further, the contact 41b is also closed. Next, when you have a rising direction after losing the direction, contact point 4
3b and 45a are closed. Now +2-43b
-45a-41b-42- In the circuit of -2, the relay 42 is energized and held by the contacts 45b and 42c, so the contact 42d is closed and the contact 42b
is open. So, this time, relays 51, 52,
54 is energized, and the up calls for the 1st, 2nd, and 4th floors are registered. When the car services those calls and reaches the first floor again in the down direction, relay 41 is not energized because contact 42a is open. When the direction of the tank is lost, all contacts 43c, 44b, and 45b are opened, so that the relay 42 is deenergized. Then, even if the car moves upward and the contact 45a closes, the relay 42 is not energized because the contact 41b is not closed. Now, as mentioned at the beginning, 1 again
Upbound calls for the floors, 3rd floor, and 5th floor will be registered.

In other words, in this example, if the power to the hall call detection circuit is cut off, each time the car arrives at the first floor, it will service the odd and even floors alternately, even though the car stops at each floor. In comparison, the amount of heat generated by the electric motor and the waiting time for passengers are both smaller.

In this embodiment, only uplink call registration has been described, but downlink calls can also be realized with a similar configuration.

Further, although only the case where the cause of the inability to detect a call is due to power cut-off has been described, it would be even better if a circuit was added to check for other causes.

In addition, the method of call service may be such that the car goes up or down depending on when the car reaches a certain floor, or it may switch between the landings in the upper half of the building and the landings in the lower half of the building, or it may skip the second floor. It may be possible to provide service to all platforms after three laps. Furthermore, the service floor switching condition may be set to time.

Also, although I have not mentioned car calls, as long as the car call circuit is not out of order, it is natural that car calls can be serviced.

Further, the present invention can be applied even when the car call circuit is out of order. However, in that case, it is necessary to specify the floor where the service will be provided in advance.

As explained above, in this invention, when a call circuit fails, all floors are divided into multiple groups and the calls within the group are automatically registered, and the groups are switched depending on the conditions, so the electric motor It is possible to suppress heat generation and reduce breakdowns, and to prevent extreme deterioration of service for passengers.
