Description

Description: TECHNICAL FIELD The present invention relates to an elevator service floor selection apparatus that can set and cancel an elevator floor landing prohibited floor by a simple operation.

[Technical background of the invention and its problems]

Recently, the usage of buildings has been diversified,
Especially in small and medium-sized buildings, so-called multi-tenant buildings, which have different stores and offices on each floor, are increasing.

In such buildings, the hours and days when the stores and offices work are different, but if the elevator stops on that floor during the hours and days when the stores and offices are closed, it is a crime prevention measure. Since it is often unfavorable, there is an increasing demand for elevators having a function of prohibiting landing of an elevator on a specific floor by a simple manual operation.

At present, one of the following three methods is used as a method for responding to such a request from a customer.

1) A service change switch is installed near the hall pushbuttons on each floor of the elevator.

2) A method of providing a switch for each floor on the car operation panel in the elevator car.

3) The car operation panel is equipped with a car button switch for service floor selection, and the service floor is registered using this car button.

However, these methods have the following drawbacks.

That is, in the method of 1), it is necessary to provide each floor response switch in the vicinity of the landing push button on each floor, which increases the cost, and when the operator specifies the flooring prohibited floor or cancels it. It is inconvenient to go to the floor.

The methods of 2) and 3) have better operability than the method of 1), but they have the drawback that the floor to be landed on can be easily changed due to mischief, etc. To avoid this, a different key is used for each floor. The cost will increase if a switch or the like is used. In addition, in the methods of 2) and 3) above, it is possible to install a switch in the manager's room and have the manager operate it in order to avoid mischief, but the manager is always in the manager's room. Not limited to this, especially in small and medium-sized buildings where no manager is resident.

For this reason, a person equivalent to the person on duty in the floor of the building operates the elevator so that it will not land on the floor during the final use of the elevator, and prohibits landing on the first use on the day of work. There has been a demand for the appearance of a service floor selection device that can easily cancel designation and prevent mischief.

[Object of the Invention]

The present invention has been made in view of the above circumstances in the background art, and only a specific person who knows a personal identification code can select an elevator landing prohibited floor with a simple operation, which is inexpensive and simple. An object is to provide an elevator service floor selection device.

Example of Invention

 Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows a schematic configuration of the present invention. A signal of a car button 1, a signal of a service floor switch 2 and a signal of a door opening button 3 provided on a car operation panel are small-sized through an input buffer 5 of a control device 4. It is input to the computer 6.

Upon receiving the above-mentioned input signal, the small-sized computer 6 performs necessary arithmetic processing, outputs the result through the output buffer 7, and outputs it to the car call response lamp 8.

FIG. 2 is a block diagram for explaining the operation of the elevator service floor selection device having the configuration shown in FIG. 1. When service floor selection is performed, when the service floor switch 2 attached to the car operation panel is operated, FIG. The small-sized computer 6 performs the following arithmetic processing.

That is, when the service floor switch 2 is pressed, a signal is given to each processing element of the car call storage 9, the car call mask 10, the password decoding 11, and the service floor determination 12, and the car call stored until that time is saved. , Preparation for car call mask evacuation, PIN code and service floor decision,
The elevator leaves normal operating conditions.

Next time the car button 1 is pressed, this signal is
Sent to and decoded. The number of code digits (for example, three digits) of the car call is set in advance, and the secret code for each floor is also set in advance. If the decoding is successful, the signal is sent to the service floor decision 12.

Next, when the car button 1 on the floor corresponding to the service floor is pressed and the conditions are satisfied, a success signal is output and the car call mask 10
To a new call answer mask is created.
Further, in order to announce that the condition is satisfied, the flicker control 13 causes the car call response lamp 8 on the corresponding response floor to flicker for a predetermined time. The flicker function may be omitted and the car call response lamp may be turned on for a predetermined time (or while the car button 1 is pressed). Further, the door open button 3 is used as a check signal for clearly determining whether the signal of the car button 1 is the personal identification code or the floor signal corresponding to the personal identification code.

When the service floor selection operation is completed in this way, the control device 4 remakes the car call and the car call mask to a state suitable for the service floor by turning off the service floor switch 2, and restores the elevator to the general service. The service floor selection is completed by this series of operations.

FIGS. 3 (a) and 3 (b) show an example of a flicker time chart. For example, FIG. 3 (a) shows that the lighting time is shortened for the announcement that the service to the floor becomes unanswered by selecting the service floor, In b), conversely, the service floor can be identified by prolonging the lighting time for announcements that have become the response floor.

FIG. 4 is a flow chart showing the basic operation of the operation in FIG. 2. When the service floor switch is operated, the existing car call is saved, and the identification code, the identification of the relevant floor and the verification with the identification code are performed. If it is established, the selection mask (response floor mask) is changed, the car call response lamp on the target floor is caused to flicker, the saved existing car call is returned and determined (required mask), and the processing is ended.

FIG. 5 is a flow chart in the case where a door open button is used as a specific existing switch in order to facilitate discrimination between the personal identification code and the floor input signal corresponding thereto. Further, FIG. 6 is a flow chart in the case where the car call response lamp on the elevator-corresponding floor is caused to flicker when the secret code and the floor corresponding thereto coincide.

As described above, according to the present invention, it is not necessary to provide a switch for service floor selection corresponding to each floor in the conventional system,
In addition, it is not necessary to have a resident manager, and it is possible for a specific person to choose whether the response of the elevator on the floor targeted by that person can be landed or prohibited, so it is possible to prevent crime on each floor on holidays or at night. Very informative.

In the above description, the door open button is used as a signal for clarifying the identification code and the relevant floor, but other existing signal sources (for example, door close button, door release button, etc.) are used. Alternatively, a dedicated switch may be used. Further, the response lamp may be lit while the car button is being pressed, or a sounding body that emits a sound when the car button is pressed may be provided to appeal to the hearing. Further, when the personal identification code is forgotten, the car call response lamps may be turned on in the personal identification code order by operating a dedicated switch or a combination of existing switches (for example, a service floor switch and a car button on the relevant floor).

〔The invention's effect〕

As described above, according to the present invention, it is possible to provide an inexpensive elevator service floor selection device that allows a specific person to select an elevator service of a corresponding floor with a relatively simple operation, and is also useful for crime prevention. It is possible to prevent the use of the elevator due to mischief for children.
