Abstract

PURPOSE:To improve service availability by performing an arithmetic process of whether another elevator is in a position capable of arriving at a generated hall call floor during a count of specified time in the case where door-open time prolonging operation has be done. CONSTITUTION:When door-open prolonging operation takes places, it is inputted into an open-prolonging operation detector, and other elevator position detection and hall call floor detection are carried out, calculating arrival predictive time (t) of another elevator with a predictive operational circuit. A comparison between specified time T and the arrival predictive time (t) takes place, and when the arrival predictive time (t) of the other elevator is shorter than the specified time T, a command for separating an open-prolonging cage 1 from control operation at once is given. Accordingly, a hall call 3 is allotted to a cage 2 so that it comes to the control operation that is less in waiting time. When t>T is the case, the command separating it from the control operation after being counted as long as the specified time. In brief, in this case, such a possibility that a close button might be pushed is high, so the cage 1 is made so as not to be separated from the control operation within the specified time.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an elevator control device.

[Conventional technology]

There is a control device for parallel elevators that organically operates a plurality of elevators that is equipped with a door opening extension device as disclosed in Japanese Utility Model Application Publication No. 51-107774.

When the monthly extension device of at least one of these elevators is activated, the control device of the parallel elevators takes this elevator out of controlled operation after a predetermined time and calls the remaining elevators for service. I'm urging you to do it.

[Problem to be solved by the invention]

Now, in the control device for the parallel elevators mentioned above, while counting the predetermined time to disconnect from the management operation during extended door open time, other elevators are not responding even if they are in a position where they can arrive at the called floor of the hall where the problem occurred. Ta. Therefore, even if a nearby landing call occurs, if the elevator that is opening the door is located between the landing call and other elevators, it will not be able to move until the predetermined time elapses, making it last longer. There are drawbacks.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned drawbacks, and its purpose is to improve the service for hall calls that occur in the vicinity of elevators whose doors are extended open. An object of the present invention is to provide a control device for parallel elevators.

[Means to solve the problem]

The above object can be achieved by calculating whether another elevator is in a position where it can arrive at the called floor of the hall while counting a predetermined time when a door opening time extension operation is performed.

[Effect]

In the case of parallel operation elevators, there is a method in which when the door open time extension operation is performed, the system is disconnected from management operation after a predetermined time, but it is necessary to perform calculation processing to see if other elevators are in a position where they can arrive at the generated hall call and arrive within the predetermined time. When it is determined, other elevators are made to respond to the generated hall call. Thereby, even if it is within a predetermined period of time, a hall call can be responded to immediately.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1.2.3.

FIG. 2A shows a hall call service state when the door opening time of a conventional parallel-operated elevator is extended.

After the door open time extension operation, if the predetermined time T (the time to prevent wasted operation when the "close" button etc. is pressed) has not elapsed, the door open time will be extended. ing. FIG. 2B shows the state after the predetermined time T has elapsed, and car 1 is separated from the management operation, and hall call 3 is assigned to other elevators 1 and 2.

An embodiment of the present invention is shown in FIGS. 1A and 1B.

In the hall call service state before the elapse of the predetermined time T in FIG. is separated from management operation, and car 2
Assign hall call 3 to . By performing this arithmetic processing and separating the car 1 whose door open time is extended from the management operation, the management operation with less waiting time can be achieved. Figure 1B shows the arrival time t for another elevator 2 to reach the floor of hall call 3.
In this case, the "close" button is likely to be pressed, so that the heel 1 is not separated from the management operation within the predetermined time.

FIG. 3 shows a concrete block diagram of the present invention.

When the opening extension operation is performed, it is input to the opening extension operation detection circuit, which detects the position of other elevators, detects the hall call floor, and calculates the arrival time t of other elevators in the prediction calculation circuit. A comparison is made between the predetermined time T and the arrival time 'r of the arrival child 811, and if the predicted arrival time t of another elevator is shorter than the predetermined time T, then immediately.

Gives a command to disconnect the open extension and 1 from management operation. t
>T, after counting the predetermined time, give a command to disconnect from the management operation. This circuit enables the operations shown in Figures 1A and 1B, and improves operating efficiency.

〔Effect of the invention〕

According to the present invention, in an elevator having a door opening time extension function in parallel operation, there is an effect of providing an improvement in operating efficiency when the door opening time extension operation is performed.

Claims (1)

[Claims] (1) If the door opening extension operation is performed in a parallel operation elevator where the door opening time can be extended within the car,
For elevators that have a function that separates the elevator from management operation after a predetermined period of time from the time when the door opening extension device is activated, even if the elevator is disconnected from the control operation after a predetermined period of time, other elevators may respond to a hall call from another floor within the predetermined period. An elevator control device characterized by having a function of identifying that arrival is possible and separating it from management operation.
