Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to an improvement in a device for operating an elevator.

There are various requirements for elevator operation. For example, reducing waiting time at the boarding point, reducing power consumption,
Missing prediction (in an elevator that predicts the car assigned to this call when the landing button is pressed, a car other than the predicted car arrives)
This includes a decrease in passenger traffic, a decrease in the number of crowded passages, and an improvement in ride comfort.

However, most of these demands are often contradictory. For example, if you are trying to shorten the waiting time at the boarding point,
This results in many cars being operated, which increases power consumption. On the other hand, if the number of buses in operation is reduced in order to reduce power consumption, the service will deteriorate and the waiting time at the boarding point will become longer. Furthermore, if cars other than those predicted to be stopped are also stopped in order to shorten the waiting time at the landing, the number of missed predictions will increase. On the other hand, if we try to reduce the number of forecast failures, the waiting time at the boarding point becomes a sacrifice.

Conventionally, as a countermeasure for these problems, measures have been taken to ensure that the requests are not too unbalanced. For example, by controlling the number of vehicles in operation according to the waiting time at the hall, it is possible to prevent the waiting time at the hall from becoming abnormally long or the power consumption from becoming extremely high. In addition, only when the waiting time at the boarding point becomes abnormally long, services can be provided for cars other than the predicted car, thereby preventing extremely long waiting times at the boarding point or an increase in missed forecasts. .

However, the type of building where the elevator is installed,
There are usually differences in the policies of administrators, preferences of users, etc. As mentioned above, it is not always good to control the situation so as to give average satisfaction to each request, so to speak. For example, some buildings prioritize energy savings and encourage the use of stairs with service taking a secondary role, while other buildings (particularly hotels) prioritize customer service over energy savings. Also, some buildings prefer to be able to board quickly even if the forecast is incorrect, while others prefer that the predicted car arrives even if it means waiting a little longer. Furthermore, the strength of the request may vary depending on the conditions. For example, if a request for power saving is received from the power company, power saving is prioritized over service, and if a large number of important customers are expected, service is prioritized over power saving. In addition, during check-in and check-out times at hotels and other facilities, where many guests with large luggage enter and exit, it is important to ensure that the forecast does not fail even if the waiting time is slightly longer (because the forecast does not match, many passengers with large luggage come and go from the elevator boarding). However, during other times, shorter waiting times are desired.

This invention was made from the above-mentioned viewpoint, and aims to provide service-oriented driving,
It is an object of the present invention to provide an elevator operation device that can change a reference signal for operations such as power saving operation, forecast failure reduction operation, etc. according to changes in the situation with a simple operation.

An embodiment of the present invention will be described above with reference to FIGS. 1 to 4.

In the figure, 1 is a control panel located in the control room, 2 is an attendant evaluation input device consisting of a three-point switch that issues a service improvement command signal 2a, a status quo maintenance command signal, and an energy saving enhancement command signal 2b, and 3 is an average waiting time display. 4 is an elevator control device; 5 is a hall call registration signal that is issued when a hall call is registered; 6
is a service evaluation device that calculates the average duration of hall calls (average waiting time) from hall call registration signal 5; 7 is a pulse signal emitted every minute; 8 is a reference signal generator; 9 and 10 are AND circuit, 11
When there is an input on the (+) side, 1 is added to the content,
When there is an input on the (-) side, 1 is subtracted and the data is stored. 11a is the reference signal which is the output, and 12 is the reference signal which is the output, and 12 is the comparison between input A and input B. Input A>Input When B, start command signal 12
13 is a start command signal 1;
2a and a stop command signal 12b, the elevator has an operating device that changes the number of operating units;

Next, the operation of this embodiment will be explained.

Currently, 6 cars are managed as a group, of which 4
It is assumed that one vehicle is in operation and two vehicles are idle. It is assumed that the content (reference value) of the reference signal generator 8 is 20 seconds stored as an initial setting value. In this state, if the average waiting time exceeds 20 seconds, one device will be started, and if it is less than 20 seconds, one device will be put to rest. (It is necessary to provide an appropriate hysteresis to prevent this, but this is omitted.)

The average waiting time calculated by the service evaluation device 6 is
This is displayed on the average waiting time indicator light 3A. Further, the power consumption of the elevator is displayed on the power consumption indicator light 3B. It is assumed that the attendant evaluation input device 2 is in the neutral position and a status quo maintenance command signal is being issued.

Here, for example, if many important customers are expected to use the service and service is to be given more importance than power saving, the staff member tilts the staff evaluation input device 2 upward. As a result, the service improvement command signal 2a is issued, and when the pulse signal 7 is input, it is input to the storage device 11 with addition and subtraction device through the AND circuit 9, and 1 is subtracted from the reference value 20, and 19 is stored. . When the input device 2 is turned down for 5 minutes, the value in the storage device 11 becomes 15. Now, when the average waiting time becomes longer than 15 seconds, the comparator 12 issues the start command signal 12a, and one more car is started and five cars are put into operation, thereby improving the service.

On the other hand, if you have received a request from the electric power company to save electricity and want to prioritize saving electricity rather than services,
The staff member tilts the input device 2 downward. As a result, the energy saving enhancement command signal 2b is issued, and each time the pulse signal 7 is issued, the contents of the storage device 11 are incremented by one. The contents of the storage device 11 are
For example, if it is 40, the comparison device 12 will determine that the average waiting time is
A stop command signal 12b is issued for 30 seconds, and one car is stopped and operated, thereby saving electric power.

In the example, the number of operating vehicles was controlled, but
It is not limited to this. For example, in a device that controls whether to prioritize reducing waiting time or reducing missed forecasts, the driving status display device 3 displays the average waiting time and the missed forecast rate, and the input device 2 displays the service improvement command signal and forecast A 3-point switch is provided to issue a command signal to improve disconnection. Then, the control device 4 is configured to additionally allocate a car other than the predicted car to a hall call for which the average waiting time exceeds a predetermined value, at the expense of a missed forecast. Here, when the input device 2 is issuing the service improvement command signal 2a, the specified amount is changed in the direction of decreasing, and conversely, when the input device 2 is issuing the forecast failure improvement command signal, it is changed in the direction of increasing. In this way, when a service improvement command is issued, additional allocation will occur even if the waiting time becomes slightly longer, and the service will be improved.

In addition, in the embodiment, there is no restriction on the increase or decrease of the reference value by the pulse signal 7, so if the staff forgets or intentionally leaves the input device 2 tilted to either side for a long time, problems may occur. be. In order to prevent this, it is sufficient to find appropriate maximum and minimum values and then make sure that they are not exceeded. Further, it would be even more convenient if the fact that the maximum and minimum values have been reached is indicated by an indicator light or the like.

As described above, the present invention allows the reference signal, which is the reference for operating the elevator in a power-saving manner or in high-service operation with less waiting time, to be changed using an externally provided input device. The operating conditions of the elevator can be changed in accordance with changes in the usage conditions of the building, making it possible to operate the elevator in optimal conditions.

Moreover, the operation of changing this reference signal is automated and simple, as if the input device is left in the input operating state for a required period of time, the reference signal will be progressively changed continuously during that time, improving operability. .

In addition, changes in the case where the elevator is operated with a reduced forecast or a high service operation can be arbitrarily changed according to the usage situation of the building.
