Description

[Detailed description of the invention] [Technical field of invention] The present invention relates to an elevator hall calling device.

[Technical background of the invention and its problems]

It is mandatory to install emergency elevators in high-rise buildings and skyscrapers over 31 meters in height, but the elevators that are normally used by general elevator users are mainly passenger elevators that serve multiple floors and multiple elevators. It is common to install group control elevators that operate efficiently.

Emergency elevators are usually installed separately from these passenger elevators, and are often used as passenger elevators, and are used only for some general elevator users and for the loading and unloading of luggage. Used a lot.

However, for general elevator users,
If the location of the passenger elevator landing is far away from the floor plan of the building, or if passenger elevators are expected to be crowded during peak demand for elevators such as lunchtime, and the waiting time at the passenger elevator landing is expected to be long, etc. Nowadays, general elevator users often use not only passenger elevators but also cargo elevators installed separately from passenger elevators.

However, in most cases, one or two of these passenger elevators are operated in fully automatic directional shared operation, and if the elevator serves many floors, it may be difficult to respond to a hall call,
As the number of car calls increases, the time it takes for a car to respond to calls from a certain floor one after another and return to that floor again, so-called one round time, becomes very long.

Therefore, general elevator users who tried to use the cargo elevator instead of the passenger elevator, after registering for a landing call, could not bear the waiting time and returned to the passenger elevator landing, or Move to the destination floor by using stairs, etc.

In this way, even though a hall call has been registered, when the elevator responds to this call, there is no elevator user on that floor, which is hereinafter referred to as a push-and-run. Since the call cannot be clearly distinguished from the general hall call where elevator users are actually waiting, all elevators are forced to respond.
However, if there are many push-and-run calls, the elevator will repeatedly run and stop in vain, which will make one round trip even longer, which is already long, and the service for actual elevator users will be extremely poor.

Actual elevator users include those who carry luggage in and out, and such people cannot use stairs etc. to move to the destination floor, and the response time is extremely long. I have no choice but to wait patiently for the elevator.

Conventionally, in order to distinguish between the actual elevator user's landing call and the push-and-run landing call, and to respond only to the actual elevator user's landing call, a landing sensor that detects people or objects in the landing was installed on each floor. It has been thought that there is no other way than to automatically disable push-and-run landing calls. but,
If a cargo elevator stops at many floors, it is necessary to install a landing sensor on each floor, and it is necessary to prevent people passing through the elevator landing from being detected. The price is high, and in many cases it is not practical to install.

[Purpose of the invention]

The present invention has been developed in view of the above points, and by clearly distinguishing between a push-and-run landing call and a landing call of an actual elevator user, the present invention improves operational efficiency and improves service to actual elevator users. To provide an improved elevator hall calling device.

[Summary of the invention]

In order to achieve the above object, the present invention provides an elevator hall call device that registers and stores hall calls for a plurality of service floors using a push button provided near the hall of each floor, and erases the hall calls by a response from the car. a device that issues an alarm to the hall side when the registered hall call memory time has elapsed for a first predetermined time; and a second predetermined time elapsed for the hall call memory time which is longer than the first predetermined time. a timer device that erases the registered hall call when the first predetermined time has elapsed, and a device that detects a second call registration and issues the alarm after the first predetermined time has elapsed and before the second predetermined time elapses; and a device that interrupts and restarts the operation of the timer device, and counts the time elapsed since each hall call is registered, thereby detecting a hall call after a certain period of time (for example, 3 to 5 minutes) has elapsed. If the elevator responds and the call is not deleted, an alarm will be issued to the hall, and the warning will be forcibly deleted after that (for example, from 5 seconds to 0 seconds), but for hall calls that are re-registered during that time, the above-mentioned fixed conditions will be applied. time (e.g. 3 to 5 minutes)
) Extend your registration.

As a result, instead of a push-and-run landing call,
If there are actual elevator users, re-registration becomes easier and it can be clearly distinguished from push-and-run hall calls, reducing unnecessary elevator operations and unnecessary stops.

[Embodiments of the invention]

Embodiments of the present invention will be described below with reference to the drawings.

The figure shows an embodiment of the present invention, and shows a circuit configuration for one hall call. 1 is a hall call button, 2 is a hall call detection relay, 2-1a, 2-2a are normally open contacts of 2, 3 is a hall call registration relay, 3-1a, 3
-2a, 3-3a are the normally open contacts of 3, 4 is the call cancellation normally closed contact when answering a hall call, 5 is the hall call duration detection timer, 5-1b is the normally closed contact of 5, 6 is the hall call alarm timer, 6-1a is 6 normally open contacts,
7 is a re-registration hall call detection relay, 7-1b is its normally closed contact, 8 is a flicker relay for hall call alarm, 8-1b is a normally closed contact of 8, and 9 is a hall call registration light.

First, when an elevator user presses 1, 2 is energized only at that time. When 2 is energized, 2-
1a is closed and 3 is energized only at that time, so 3
-1a is closed and 3 is self-holding. When 3 is excited, 3-3a closes and 9 lights up. Also 3-
Since 2a is also closed, 5 and 6 are pressurized, and both start counting the elapsed time from the call registration.

If the elevator responds to the hall call registered by the elevator user, it is normal;
The details will not be described here, but since 4 is open and 2 is no longer excited, 3-2a is open and 5 and 6 are reset, 3-3a is also open, and 9 is turned off.

However, when a certain period of time (for example, 3 to 5 minutes) has elapsed at 6 before the elevator responds to the hall call, the coil is excited and 6-1a is closed. When 6-1a is closed, 8 is excited, its contact 8-1b opens and closes, and 9 flickers. If the elevator user presses 1 again during that time, 2 will be energized only during that time, so 2-
2a is closed and 7 is excited. As a result, 7
-1b opens and the timers 5 and 6 are reset once, but then start counting again.

If the elevator user does not press 1 again, the time set in step 5 is set longer than the time set in step 6 (for example, from 5 seconds to 10 seconds), but when the time specified in step 5 has passed, the coil is excited and 5-1b opens. Therefore, 3 is no longer energized, the hall call is forcibly erased, and 3-3a
opens and 9 turns off. At that time, 3-1a opens, so 1 is pressed again, 2 is energized, and 2
3 will not be energized again unless -1a is closed. Further, since 3-2a is also opened, 5 and 6 are reset.

According to the above, if the elevator does not respond after registering a hall call, the hall call will be flickered after a certain period of time to issue an alarm, and if there are actual elevator users during that time, it will be easier to register again. ing. However, in the case of a push-and-run hall call where there is no actual elevator user, it is not re-registered during that time, and the hall call is then forcibly deleted, reducing wasteful operation and stoppages and improving elevator operation efficiency. I can do it.

Therefore, the hall calls of these two companies can be clearly distinguished, and the service to actual elevator users can be improved.

The embodiment shown in the figure is described for one hall call, but is actually implemented for all hall calls.

The fixed time period determined for each hall call may be the same for all floors, or may be set separately for each floor call.

Further, the difference between the times set in No. 5 and No. 6 may be the same for all floors, or may be set separately for each floor.

Further, for a hall call for one or more places such as a floor where elevators are actually used frequently, the present invention may be used instead of a normal hall call without forced deletion.

Although one embodiment of the present invention has been described using a relay sequence circuit, it is of course possible to configure this using microcomputer software.

Furthermore, although the present invention is limited to emergency elevators, it can also be used as is for general passenger elevators.

〔Effect of the invention〕

As described above, according to the present invention, in an emergency elevator installed in a high-rise building or a skyscraper exceeding 31 meters, which is mainly used as a passenger elevator, after registering a hall call, the elevator does not respond. If a certain period of time has elapsed, a warning will be issued to the elevator hall, and if there are actual elevator users during that time, it will be easier to register again.
However, in the case of a push-and-run hall call where there are no actual elevator users, the hall call will not be re-registered during that time, and the hall call will then be forcibly deleted. Therefore, it is possible to reduce unnecessary operations and unnecessary stops due to push-and-run landing calls, and improve the operating efficiency of the elevator.

For this reason, it is possible to clearly distinguish between a push-and-run landing call and a landing call made by an actual elevator user without installing a landing sensor to detect people or objects waiting at the landing. service can be improved.
