Abstract

PROBLEM TO BE SOLVED: To newly provide a reaction switch method for automatic door and its device such that a person does not falter to fall down by laying an extremely thin mat having a simple structure.SOLUTION: A downward antenna is provided above a gateway along an automatic door, and an extremely thin mat having a plurality of reaction tags for reaction transmission each including an IC tag embedded in a scattered state is load on the floor under the gateway. When a person or body steps on the mat to cut off a reaction signal between the antenna and the reaction tags, so that the automatic door is automatically opened.

Description

  The present invention relates to a reaction switch method such as opening and closing of an automatic door using an antenna and a mat, and an apparatus therefor.

Japanese Utility Model Laid-Open No. 7-21980, issued prior to the filing of the present invention, describes that a paragraph part a is formed in a flooring material, and mat switches 17 and 20 having a thickness are laid on the paragraph part a. .
The mat switches 17 and 20 each have a thickness when a plus or minus electrode connected to each other by electric wiring is placed in a space, so that a step is eliminated by providing a paragraph portion on the flooring 14.

Japanese Utility Model Publication No. 7-21980

  However, the mat switch requires many complicated processes including electric wiring for its formation, and it takes time to lay and becomes expensive. In addition, the mat switch has a thickness as described in the above publication. There is a problem in that a person trips over and falls if a paragraph part is provided on the surface and not laid.

  The present invention lays an ultra-thin mat formed by embedding a plurality of reaction tags including a downward-facing antenna on an entrance / exit along an automatic door and a reaction tag including an IC tag below the entrance / exit. This problem is solved by automatically opening the automatic door by blocking a reaction signal between the antenna and the reaction tag by stepping on a person or an object.

  According to the present invention, since the mat switch can be remarkably thinned, there is an effect that even if the mat is placed as it is without forming a paragraph or the like on the floor surface, a person or an object does not trip and fall.

  Since the mat eliminates the need for electric power by embedding the reaction tag, it has the effect of eliminating the need for lead wires and the like that have been connected in the past, making the equipment simple and free of failure.

  There is an effect that it is easy to prevent dogs and cats from opening the automatic door even if they step on the mat.

  By detecting the reaction order of a plurality of reaction tags, there is an effect that it is possible to confirm the movement of a person or an object in the traveling direction.

  There is an effect that it can be used for crime prevention by setting the antenna and reaction tag as one set and facing each other.

Sectional drawing which shows the mat structure of a prior art example

In the present invention, a transmission / reception antenna is mounted downward on an entrance / exit along an automatic door, and a plurality of reaction tags including IC tags that transmit in response to transmission of the antenna are scattered below the entrance / exit at appropriate intervals. A very thin mat, which is horizontally embedded, is laid, and a person or an object rides on the mat and steps on one or more reaction tags to cut off the reaction for the antenna. There is a reaction switch method with an antenna and mat, such as opening an automatic door by operating.
In addition to IC tags, reaction tags can be replaced with other tags as long as they have the same quality.

  FIGS. 1 and 2 show a first embodiment in which electromagnetic waves are freely set in the middle of the upper and lower entrances and exits along the automatic door 1 by specifying a certain angle such as a sector, a radial, or an oblique direction. A pole in which a transmission / reception antenna 2 capable of transmitting electromagnetic waves is mounted downward, and a plurality of IC tags 4 having thin and small squares are horizontally embedded on the floor 3 below so as to be scattered at regular intervals. A thin mat 5 is laid and the antenna 2 is adjusted in the direction of each IC tag 4. When a person or an object comes on the mat 5 and steps on the IC tag 4 to cut off the electromagnetic wave between the antenna 2 and the antenna 2, the automatic door 1 is opened through the reading reader 6 connected to the antenna 2 and the controller 7. .

  When a person or an object enters the room from the opened automatic door 1, the automatic door 1 is closed because the electromagnetic wave between the antenna 2 and the IC tag 4 is released.

  Conventionally, as shown in FIG. 6, when a space 8 extending horizontally is provided in the mat 5 and a large number of upper and lower electrodes 9a and 9b are provided in this space and the electrode 9a is stepped on and brought into contact with the electrode 9b, the lead wire 10 Since the automatic door 1 is opened by sending an open signal to the automatic door through the mat, since the mat 5 has a thickness, the front surface of the automatic door 1 is formed with a dent corresponding to the thickness of the mat 5 so as to eliminate the step. Then, it took a lot of time and expense to install the mat 5 there, but since the present invention only embeds the extremely thin IC tags 4 so as to be scattered, the mat 5 Is extremely thin and can be formed in a short time, so that it can be used without stumbling by simply laying without forming a concave step and without requiring wiring such as a lead wire.

  In order to prevent the automatic door 1 from opening even when a dog, cat or the like gets on the mat 5, it does not react unless two or three IC tags 4 within a certain interval are stepped on simultaneously to block electromagnetic waves. It can also be.

  In addition, it is possible to confirm the movement of the person or the object passing through the mat 5 such as the traveling direction by identifying and detecting the reaction order of the plurality of IC tags 4 at intervals.

  Since the IC tag 4 is built into the mat and does not reduce its effect even if it gets wet with water or dust adheres, the mat of the present invention is maintained and managed even when compared to an electrode contact / separation type mat and an infrared detection system. Therefore, it can be used continuously for a long time with few failures. Note that the mat 5 in which the transmission / reception antenna 2 and the IC tag 4 are embedded can be relatively disposed on the left and right wall surfaces 3a and 3b with the automatic door 1 interposed therebetween as shown in FIG.

  FIG. 4 shows a second embodiment of the present invention. As a key point of a house or the like, for example, a set of the transmission / reception antenna 2 and the IC tag 4 is relatively arranged on a certain section on the fence 11 and both sides of the entrance. Thus, an intrusion prevention alarm is issued when a person or object enters the relative arrangement section.

  In addition, by placing the transmitting / receiving antenna 2 and the IC tag 4 as a set relative to the entrance of a restricted area such as a factory or the operation position of a mechanical facility, entry into the prohibited area is prevented and there is no operator on the mat. It can also be used for applications such as stopping the machine in a state. In these cases, safety and accuracy of confirmation can be further enhanced by combining access permission and machine operation with an approved separate identification reaction tag.

  FIG. 5 shows a third embodiment of the present invention, in which the transmission / reception antenna 2 is directed downwardly above the exhibit placement table 12 in the exhibition room, and the IC tag 4 is attached below the exhibit A on the placement table 12 directly below. Thus, an alarm is issued when the exhibit A placed on the mounting table 12 disappears due to being taken away.

  In any case, the present invention always monitors a reaction tag by a transmission / reception antenna and uses it as a reaction switch for controlling an operation device or the like as a so-called fail-safe when the monitoring state between the antenna and the reaction tag is interrupted. It is something that can be done.

  With a simple and thin mat embedded with a reaction tag including an electromagnetic wave transmission / reception antenna and an IC tag, the automatic door can be opened and closed stably over a long period of time, and it can be used for various crime prevention and safety devices. It is widely used.
