Elevator calling button and elevator operation unit having the same and method for driving elevator operation unit

The present invention relates to an elevator, and in particular, an elevator call button having a function that can inform the information of the floor by voice just by touching the floor with a finger before selecting and driving the elevator operating panel and the elevator operating panel having the same. It's about how.

For modern people who use tall buildings, elevators are an indispensable device.

In general, the passenger must press the call button of the floor in the elevator car to travel to the desired floor in the elevator. In this way, when the call button is pressed, the elevator driving control device detects this and notifies the passenger by lighting a call registration LED indicating that the floor is selected. Then, the service to guide the passenger to the floor is in progress.

An elevator having such a function can be used without inconvenience for passengers other than the visually impaired. However, when the visually impaired are used, it is inconvenient that the call button information of the desired floor cannot be known. This requires an elevator call button for visually impaired people to know the call button information of the desired floor.

An elevator call button according to the prior art will be described with reference to the accompanying drawings.

The metal plate 16 disposed on the circuit board 11, the dimming plate 17 arranged to have a predetermined distance from the push button switch 12 on the inner surface of the metal plate 16, and the push button switch 12. It consists of a spring 18 provided to return.

The elevator call buttons as described above are arranged in a plurality of elevators at a predetermined interval as many as the number of floors of the building.

As described above, the conventional elevator call button is provided with a concave-convex portion 15 in braille on the call button so that the visually impaired person can move to a desired floor.

However, such a conventional elevator call button has the following problems.

First, it takes a lot of time to find out the information of the floor by reading the uneven portion 15 in which the blind is braille.

Second, it is difficult to recognize the fact that the information on the floor is read incorrectly and the push button switch is pressed incorrectly.

Third, the area of the floor number is limited because the call button should be secured as much as the concave-convex portion 15 in braille, and there is a limit in reducing the area of the elevator call button.

In order to solve the above problems, the present invention is an elevator call button that can inform the information of the floor by voice just by touching the floor before selecting the finger, and the elevator operating panel and elevator driving panel having the same The purpose is to provide.

The touch plate is made of a conductive metal plate to detect a change in capacitance.

And, the elevator operating panel according to an embodiment of the present invention having an elevator call button having the above configuration is provided with a plurality of call buttons having a touch plate and a touch sensing circuit to detect and output a change in capacitance of the user. A floor call button switch unit; A control button switch for controlling the door opening and closing of the elevator; A voice guidance apparatus for audibly notifying the floor information and the driving registration state of the touched call button; The floor call button switch unit, the control button switch and the voice control device is characterized in that it consists of a control panel control unit.

In addition, a plurality of call buttons of the call button switch unit are provided in proportion to the number of floors of the building.

In addition, the elevator driving panel driving method according to an embodiment of the present invention comprises a first step of determining whether the finger touches the elevator call button; If it is determined that the finger touches the elevator call button, outputting the touched number of the corresponding floor by voice; A third step of determining whether the push button switch of the call button of the touched floor is pressed; A fourth step of guiding a call registration tone by voice when the push button switch is pressed; If the push button switch is pressed is characterized in that it comprises a fifth step of lighting the LED of the call button.

The elevator call button of the present invention having the above configuration features and the driving method of the elevator operating panel and the elevator operating panel having the same have the following effects.

First, since the information of the floor can be voiced by simply touching the elevator call button without checking the braille, it is easier for the visually impaired to select the desired floor.

Second, since the conventional buttons are not required in the call button, in the case of the call button having the same size as in the related art, an area capable of displaying the floor number is increased, thereby improving visibility of the floor number.

Third, since the information of the layer to be registered is first voiced before registering the call button, it is possible to prevent a mistake in pressing the call button.

Fourth, since it is possible to be notified whether a call is registered in the corresponding layer according to the operation of the call button by the call registration tone, there is a convenience of confirming that the operated call button is registered.

Fifth, since the metal plate can be used as a touch plate without changing the metal plate of the call button, it is easy to implement a touch call button.

Prior to examining a specific embodiment of the present invention, the present invention is implemented by adding a touch switch to the mechanical button switch of the floor call button of the elevator, it is necessary to first understand the operating principle of the touch switch. In particular, the present invention uses a capacitive touch switch, and the principle thereof will be described.

Nowadays, many touch switches are used in mobile phones and home appliances. Among such touch switches, the capacitive touch switch detects the capacitance generated in the human body and determines the presence or absence of the operation, and thus the appearance of the switch can be hidden.

The capacitive touch switch is a switch that senses the touch of the human body, which can be expressed as a "switchless switch", which goes beyond the concept of a conventional switch. In other words, it is a method of detecting a capacitance of a human body and is mounted inside a case of an application device to detect external contact. Accordingly, there is no need for a mechanical device for installing a separate switch on the outside of the product and there is no mechanical operation, so it has a great superiority in terms of design and reliability.

The principle of detecting the capacitance of the human body in such a capacitive touch switch is made by detecting a change in capacitance generated by the user's human body 31 and the surrounding environment.

At this time, the capacitance caused by the user's human body 31 and the surrounding environment, as shown in Figure 3, the first capacitance (Cx1) generated between the floor 32 and the sensor 33 used as the ground and And a second capacitance Cx2 generated between the human body 31 and the sensing electrode 34, and a third capacitance Cx3 generated between the human body 31 and the bottom 32.

The capacitance generated by the human body 31 and the surrounding environment is only a very small capacity (a few pF), and how accurately it is detected is important.

As such a capacitive sensing method, a method of detecting and changing the frequency generated by the capacitance converted by the human body is used.

For example, as shown in FIG. 4A, when there is no contact with the human body, the total capacitance Cto is Co, and the period of the frequency generated from the frequency generator 41 is To.

However, as shown in FIG. 4B, when touched by the human body, the total capacitance Ct becomes Co + Cbody, and as a result, the period of the frequency generated from the frequency generator 41 changes to To + ΔT. do. In this way, even the smallest change can be detected by sensing the capacitance sensed by the touch of the human body.

As described above, the present invention applies the feature of the capacitive touch switch to the elevator call button, and implements by adding a touch switch to the mechanical button switch.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings and embodiments.

The touch plate 56 is formed of a conductive metal plate to detect a change in capacitance, and the touch sensing circuit unit 59 turns on / off a change in capacitance of the touch plate 56. It distinguishes and outputs by signal.

The LEDs 53 may be arranged in plural so as to have a predetermined interval on the edge portion of the printed circuit board 51.

In addition, the light control plate 57 serves to evenly light the light emitted from the LED 53 to the floor number 54, and is also reflected on the edge of the touch panel 56, and thus the driving registration state of the call button. It may be configured to have a larger area than the touch plate 56 so as to know.

A plurality of elevator call buttons provided with the touch plate 56 and the touch sensing circuit unit 59 are arranged in the elevator of the building at predetermined intervals by the number of floors of the building.

Hereinafter, an elevator operating panel according to an embodiment of the present invention having the above-mentioned elevator call button will be described.

As shown in FIG. 7, the elevator operating panel 70 according to an exemplary embodiment of the present invention includes a plurality of call buttons provided with a touch plate and a touch sensing circuit to detect and output a change in capacitance. A call button switch unit 71, a control button switch 72 for controlling the door opening and closing of the elevator, a voice guidance device 73 for audibly informing the floor information and the driving registration state of the touched call button; The control panel switch 74 controls the floor call button switch unit 71, the control button switch 72, and the voice guidance apparatus 73.

For reference, the elevator is provided with an elevator running control device 75 for controlling the elevator running through communication with the elevator operating panel having the above configuration.

Referring to the configuration operation of the elevator operating panel having the above configuration, as shown in Fig. 7 and 8, first, it is determined whether the finger touched the elevator call button (S81), if the finger touched the number of the floor touched To output the voice through the voice guide device 73 (S82). At this time, if it is determined that the call button is not touched, the standby state (S80) is maintained.

In the above operation, the operation of determining whether the call button is touched and guiding the floor number to the voice is as follows. When the capacitance change is detected and the touch sensing circuit unit 59 outputs an ON signal, the ON signal of the touch sensing circuit unit 59 is transmitted to the control panel controller 74, and the control panel control The device 74 outputs the information on the touched floor through the voice guide device 73 as a voice (S82).
