Abstract

PURPOSE: To prevent the abuse of a release button for the purpose of mischief, a crime, or the like by constituting a release function impeding system in such a way that release function does not act even if a release button is pressed again in a specified period after pressing the release button. CONSTITUTION: This system is provided with a reference voltage generating circuit 2 for generating predetermined reference voltage Eo, and an integrating circuit 3 connected to a release button 300 and outputting successively integrated generated voltage (e) in association with pressing-down of the release button 300. The voltages Eo, (e) are inputted to a comparator 4. The comparator 4 outputs a signal for energizing a release function impeding relay 400 in the case of the reference voltage Eo being larger than the generated voltage (e). A normally open contact 400a is closed by energizing the release function impeding relay 400, and in a closed period of the normally open contact 400a, release function does not work even if the release button is pressed down. At a time point of the generated voltage (e) reaching the reference voltage Eo, the relay 400 is de-energized so as to be releasable thereafter at the time of pressing the release button 300.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an elevator destination floor release function blocking system that temporarily interrupts the release function of a destination floor button by operating an in-car operation panel of the elevator. It is something.

[Conventional technology]

FIG. 4 is a diagram showing the circuit configuration of a conventional system for registering and canceling the destination floor of an elevator.

Corresponding to the destination floor of the elevator, car buttons (1), car call relays (101), ... (106), ..., and normally closed contacts (201b), ... (206b), ...
are connected in series, and each car button (
1) Call relay (101), -(108)
, -... normally open contacts (101a), ... (106a
), ... are connected in parallel. Click the basket button (1
) and a release button (300) are connected to form a circuit. In such a circuit configuration, if you want to register the 6th floor as the destination floor, for example, press the car button (1) corresponding to the 6th floor and press the release button (30
0), a closed circuit is constructed through the car button (1), the car call relay (106), and the normally closed contact (206b), and the normally open contact (108a) is activated by the operation of the car call relay (108). The circuit is closed, a closed circuit is formed, the destination floor is registered, and the elevator starts ascending or descending to the designated destination floor, the 6th floor.

In this case, after pressing the car button (1) for registering the destination floor, if the user realizes that he has made a mistake and wants to cancel the registration, he can press the cancel button (300). Then, the above-mentioned closed circuit is opened, and the normally open contact (toaa
) will open again, and the previously registered destination floor will be cancelled. In this manner, the conventional circuit for registering and canceling the destination floor of an elevator is configured such that the function for canceling the destination floor registration can be used regardless of the time or number of times.

Therefore, in the conventional system, after specifying the destination floor on the in-car operation panel and pressing the car button (1), if you realize that you pressed the wrong button and press it again, the previously registered destination floor is always canceled. It had become.

[Problem that the invention seeks to solve]

The conventional system was configured as described above, so
When a destination floor is registered by pressing a car button on the in-car operation panel, there was no ability to prevent abuse of the function to release the button. Therefore, the problem of the release button being misused by unlimited use for purposes such as mischief or crime has been eliminated.

This invention was made in order to solve the above-mentioned problems, and the invention was made in order to solve the above-mentioned problems. The purpose of the present invention is to provide a release function blocking system.

[Means for solving problems]

The elevator destination floor release function prevention system according to the present invention includes a car button for registering the destination floor of the elevator, a release button for releasing the registered destination floor, and a car button that is reset to a predetermined value in response to pressing of the release button. an integrating circuit that sequentially outputs the generated voltage integrated over a period of time; and an integrating circuit that compares the generated voltage with a reference voltage and presses the release button if the reference voltage is greater than the generated voltage within the predetermined period. A release function blocking relay is provided to inhibit the release function of the destination floor.

[Operation] If the release button is pressed twice or more within a predetermined period, the blocking system in this invention considers this to have been pressed for the purpose of mischief or crime, and energizes the release function blocking relay. It will not work even if you press the release button again. When a predetermined period of time has elapsed, the release function blocking relay is deenergized and the release button is activated again.

〔Example〕

An embodiment of the present invention will be described below based on the drawings. 1st
The figure shows a circuit connection diagram of an electric circuit portion used in an embodiment of the present invention.

In the following drawings, the same elements as those of the conventional component shown in FIG. 4 are denoted by the same reference numerals, and detailed explanation thereof will be omitted.

The circuit in Figure 's1 shows the electrical circuit connection diagram of the part corresponding to the 6th floor. The normally open contact (400a) of the release function blocking relay (400) is connected in parallel to the release button (300). The other configuration is almost the same as the conventional case shown in FIG.

FIG. 2 is a block diagram showing an example of a drive circuit for the release function blocking relay (400) provided according to the present invention. A reference voltage generation circuit (2) for generating a predetermined reference voltage E0 is connected to a release button (30G), and as the release button (300) is pressed, it sequentially outputs an integrated generated voltage e. An integrating circuit (3) is provided, and these voltages Eo and e are respectively input to a comparator (4). The comparator (4) outputs a signal for energizing the release function blocking relay (400) when the reference voltage Eo is greater than the generated voltage e. Release function blocking relay (400
) is energized, the normally open contact (4) shown in FIG.
00a) is closed and the normally open contact (400a) is closed, the release function does not work even if the release button (300) is pressed.

FIG. 3 is a waveform diagram showing the operation of an integrating circuit that is reset in response to pressing the release button and sequentially outputs the generated voltage integrated over a predetermined period. (300) is pressed, the integrating circuit (3) shown in FIG. (4) Output. First press the release button (30
0) is pressed at time t1 and pressed again at time t2 after time TI has elapsed.

In this case, the integrating circuit (3) is reset and starts the integrating operation again from time t2, but the generated voltage e at time t2 is the reference voltage E. Since the comparator (4) outputs a drive signal to energize the release function blocking relay, the release function blocking relay (4) responds to this.
00) is activated, and the operation of the release button is prohibited from now on.

Therefore, even if the release button is pressed at time t2, the release function no longer works. On the other hand, the integral port/path (3) that started its integral operation at time t2 successively generates a generated voltage e, and after time To has elapsed from time t2, the difference in the magnitude of the generated voltage e becomes the reference voltage. It becomes equal to the size of Eo. At this point, the comparator (4) is connected to the release function blocking relay (4).
00), the release function blocking relay (4
00) is deenergized and the normally open contact (400a) of the release function blocking relay (400) opens again, so the release button (300)
function is restored. Therefore, at time t3, the release button (3
00), the release function operates.

In this way, the generated voltage e is the reference voltage E. The release function blocking relay (400) is kept energized during the period To until reaching . During this period To, even if the release button (300) is pressed again, the release function will not operate because the blocking relay (400) is working. Release function blocking relay (400) when the generated voltage e reaches the reference voltage E0
By deactivating the button, the release button (300) will be activated from then on when the release button (300) is pressed.

Note that in the embodiment described above, the reference voltage E is used. The release function blocking relay was activated by comparing the generated voltage e with the release button, but the timer activated the release function blocking relay for a certain period of time after pressing the release button, and turned it off after a certain period of time. A similar effect can be obtained by adopting a configuration in which the

Furthermore, a comparator judges the number of people obtained by weighing the number of people in the elevator car using a scale (a) and the number of people obtained from the call counter (b), and the number of people obtained from the call number counter is measured by the scale. Number of people signal obtained by (a)
It is also possible to configure the release function blocking relay to be deenergized in a state where it becomes larger than .

〔Effect of the invention〕

As described above, according to the present invention, after the release button is pressed, the release function is configured so that it does not operate even if the release button is pressed again within a certain period of time, so that the desired floor is not activated for the purpose of mischief or crime. This has the effect of preventing this even if you try to prevent it from stopping.
