Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention targets a plurality of elevators installed in parallel for a plurality of four floors, and selects and determines an answering machine to respond to a common hall call. The present invention relates to group management control of elevators, and in particular to an elevator control method that takes into consideration the possibility that the hall call detection function may fail.

[Technical background of the invention]

Elevator group management control is performed in order to efficiently operate a plurality of elevators installed in parallel.

The group management thoracotomy device selects the most suitable machine for the generated hall call based on the information of various elevators, and sends the output of the assignment to the individual operation control device of that elevator. The individual controller of the elevator that receives the assignment output selects the hall call direction based on this hall call assignment.

If the hall call detection device that detects hall calls becomes unable to detect hall calls for some reason, even if the group management control device and the individual control devices of each elevator are normal, Since call information is no longer input, it becomes impossible to output hall call allocation information to the individual control devices of each elevator machine.

Conventionally, in such cases, failure detection information of the hall call detection function was input to the individual control device of each elevator machine, and in order to deal with the inability to detect a hall call, even if the group management control device was normal, each elevator Switch off the control between the individual control device of each elevator machine and the group management control device.P1 For each elevator machine alone, each floor can be stopped, skipped, or f-operated, or some floors determined for each elevator machine can be operated. In an effort to ensure the minimum level of service to passengers, the train stopped operations at each floor between the two.

However, in this case, there is no hall call information, so the number of unnecessary stops increases significantly, and each elevator takes almost the same length of time, and the round trip time becomes extremely long. Once clustered in close proximity,
Since the so-called continuous operation of stopping at each floor continues for a while, the waiting time at each floor becomes significantly longer, and the operating efficiency deteriorates significantly.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide an elevator control method that can improve operating efficiency by shortening the waiting time at the hall as much as possible even in cases where hall call detection becomes impossible.

[Summary of the invention]

The present invention is characterized in that when it becomes impossible to detect a hall call, departure interval control is performed on a specific floor to cause each elevator machine to stop at each floor.

[Embodiments of the invention]

An embodiment of the present invention will be described by taking as an example a case where the number of group management control types is three aircraft, that is, three aircraft, A to C, are group controlled.

Figure #12 shows an example of the format of the control output output from the group management control device rjIt2 to the individual control devices 81 to 8@ of each car.

Next, a control method according to this embodiment will be explained based on such a configuration.

When the hall call detection function is normal, the group management control device 7 in FIG. The call is transmitted via transmission line 5. Also, the landing call logic.

When the hall call detection function is disabled, the evening circuit 6 transmits information that the hall call detection is impossible to the #-# physical control device 1 via the transmission line 2t. This gives d −1ffi *l

In the departure interval control routine between 1.12 and 12, each elevator is controlled based on the information of each car that was previously input.

No. 4114 (1), (b) is a flowchart showing eleven details of the departure interval control routine, and the details will be explained to him.

Following this routine, the information for the hall call detection function described above is input, and if the disabled state continues, the operation returns to the first stage of the operation at the time of failure of detection, and the above-mentioned operation continues until the hall call detection function is closed again. control.

Next, details of the departure interval control routine shown in FIGS. 4(a) and 4(b) will be explained.

This routine is a control routine that has a function of controlling the interval between elevators that are stopped at each floor to be constant. Originally, in this embodiment, this control routine is executed from the group management control device 7 to each elevator control device Jl.
This is done for a-8@, and the group management control device 1 restrains returning elevators at the standard floor based on the car information of each elevator, and returns them to the standard floor at regular intervals according to traffic requirements. The idea is to control each elevator by starting the train.

FIG. 4(a) is a routine that generates a control output for restraining the car that has returned to the reference floor and a reset output for the designated car that is to depart next.

First, it is determined whether each elevator is the leading one, and for the leading elevator, the connector 82 is advanced, and the previous leading elevator, that is, the floor currently in the middle, is manually changed to the car position (il) of the elevator that is currently in stop operation at each floor. When that position exceeds a certain set value, that is, when the car departs from the previous reference floor and is further away from the setting II floor where there is a floor difference, a car restraint reset output is given to the designated starting car at that point. The car restraint on the reference floor of that car is released and each floor is stopped.At the same time, the previous car storage table 0
The LDSC is updated and the starting machine storage table is reset to determine the next starting designation.

On the other hand, for each car other than the car designated as the advance car, we check whether the car position has returned to the standard floor, and when the car position reaches the standard floor, we take measures to prevent the car from immediately starting the stop operation at each floor. A car restraint set output is given to the corresponding car, and as a result, the corresponding car waits on the reference floor with its doors closed.

# following Figure 4 6)! Figure 4 (b) is a routine that generates a designated starting set output as the designated starting aircraft is reset, and it is determined whether or not there is a designated starting aircraft, and if there is no designated starting aircraft, it is restrained at the standard floor. Read the presence or absence of a car, and if there is a car restricted number, select the 1ws among them.
By selecting a car as the starting car and giving the specified starting set output to that car, the door of the corresponding car is opened, and the car moves on the reference floor until the distance from the previous car exceeds a certain value. to bound.

By controlling the trains to depart from the reference floor at regular intervals in this manner, it is possible to effectively prevent the so-called "dunf" operation of multiple cars, where each floor is stopped.

It should be noted that the present invention is not limited to the embodiment described above and shown in Figure RkiK, and can be implemented with various modifications within the song without changing its gist - For example, in the above embodiment, in the standard floor The departure interval is controlled based on the position of the last starting corner, that is, the mutual positional distance between the cars. However, the departure interval may also be controlled not only on the standard floor but also on both ends of the standard floor and the top floor. Departure intervals may be controlled not only by time but also by time, and when dividing a service floor into zones, etc., departure intervals may be controlled on floors based on certain criteria for each zone. Same goes for these cases! j1! Alms can be processed using a similar routine.

Further, although information on hall calls is not input, wasteful driving can be prevented to some extent by predicting traffic demand based on the weight of each car, the number of car calls, etc., and changing the departure interval setting value LIMIT.

FIG. 5 shows a flowchart of an example of the operation in such a case.

Figures 1 and 5 show connectors B21 and 8 in Figure 4.
This routine is inserted between 22 and 22. When this routine is first entered, the average number of car calls occurring in one round of operation of each car is calculated, KCALN, and this KCALN is compared with the preset number of car calls, LIMITI. S, K.C.A.
Only when LN is greater than or equal to LIMITI, the departure interval setting 1* LIMITI is lowered by the correction value HO8EI and subsequent processing is performed.

〔Effect of the invention〕

According to the present invention, even if a hall call detection function fails due to an elevator group management control system in which a plurality of elevators are installed in parallel and a service elevator is selectively determined and responds to a common hall call, By performing departure interval control, it is possible to provide an elevator control method that can shorten the waiting time at the landing as much as possible and improve the operating efficiency.
