Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to distribution management of merchandise or articles for which an object to be identified is to be instantly identified in a remote state, process control in manufacturing, and management of personnel such as vehicles or vehicles.

[0002]

2. Description of the Related Art Conventionally, although there are those having a primary electromagnetic wave transmitting section, a secondary electromagnetic wave transmitting section, a secondary electromagnetic wave receiving section and an identification control section as constituent elements, the secondary electromagnetic wave transmitting section has a primary electromagnetic wave receiving and It is, so to speak, a device body having an antenna and an electric circuit for transmitting secondary electromagnetic waves. There is a so-called bar code system in a system device that identifies products and articles relatively close to each other. In this, an electromagnetic wave such as a laser beam having a specific wavelength is applied to a selectively reflecting pattern portion (bar code) provided on an object to be identified, and the presence / absence of the reflection is used as an identification signal.

[0003]

The above-mentioned conventional technique is
In the former case, since the secondary electromagnetic wave transmission section constitutes the device body, it is complicated, bulky and expensive, and the range of use is restricted. In the latter bar code system, the bar code printing or reading device requires high precision. Use in remote conditions has a difficult problem. According to the present invention, the identification of the identification object can be instantly realized at a very low cost in a remote state, and the above-mentioned problems can be solved.

[0004]

The present invention mainly comprises a primary electromagnetic wave transmitting section, a secondary electromagnetic wave transmitting section, a secondary electromagnetic wave receiving section and an identification control section.

[0005]

With this structure, the primary electromagnetic wave is radiated to the secondary electromagnetic wave transmitting section by supplying required energy such as electric power to the primary electromagnetic wave transmitting section. At this time, the primary electromagnetic waves are generally in the form of radio waves, far infrared rays, visible rays, ultraviolet rays, X-rays, etc. depending on the wavelength and energy thereof, and can be generated by oscillation by an electric circuit, heating of an object, discharge or other methods. Further, it is possible with the conventional technique to give directivity to these and to transmit them if necessary. Only the secondary electromagnetic wave transmitter is provided on the identification target. The main component of this is 1
Atom that is physically excited by the next electromagnetic wave and emits a secondary electromagnetic wave of a specific wavelength. It is formed as an ink and is directly printed on the object to be identified or attached by a separately printed label-like object. Or, it can be mounted as it is. The secondary electromagnetic wave receiving unit and the identification control unit detect the secondary electromagnetic wave by a method according to each of the above modes, and identify whether or not the secondary electromagnetic wave is a preset secondary electromagnetic wave. By combining a plurality of primary electromagnetic waves and secondary electromagnetic waves or scanning the primary electromagnetic waves, it is possible to use the combination and order of the secondary electromagnetic waves as a signal, and the diversity of the identification object can be dramatically increased. . The control unit controls each component itself or the whole.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiment of the present invention shown in FIG. 1 will be described below. In the figure, (1) is the primary electromagnetic wave transmitter, (2)
Is a secondary electromagnetic wave transmitter, (3) is a secondary electromagnetic wave receiver,
(4) is an identification control unit, and (5) is an identification object, and the secondary electromagnetic wave transmission unit of (2) is provided in this. Further, (1) the primary electromagnetic wave transmitting unit, (3) the secondary electromagnetic wave receiving unit, and (4) the identification control unit may constitute a device on the identification side and be integrated together. For convenience of explanation, (10) shows a primary electromagnetic wave and (20) shows a secondary electromagnetic wave.

As an example, when an ultraviolet ray generating lamp is used in the primary electromagnetic wave transmitting section (1) and a fluorescent substance made of a rare earth element is used in the secondary electromagnetic wave transmitting section (2), the primary of the former (1) is used. The wavelength of the electromagnetic wave (10) is 352 nm, but the secondary electromagnetic wave (2
0) has a wavelength of 62% depending on the type of the fluorescent substance of the latter (2).
It is known that red of 5 nanometers, green of 535 nanometers, blue of 445 nanometers, and the like can be obtained. In the secondary electromagnetic wave transmitting section (2), these substances are displayed on the surface of the identification object (5) by printing or the like based on a predetermined combination or order. The plurality of rectangles in FIG. 1 have different kinds of compositions,
Further, a rectangle represented by a broken line including each rectangle indicates a set of them. The identified object (5) is actually a product, a material,
It is composed of objects such as vehicles. As a result, the secondary electromagnetic wave (20) detected by the secondary electromagnetic wave receiving unit (3) is identified and controlled by the identification control unit (4) by collating the combination or order according to the type with the promise signal. The order signal can be identified by scanning the secondary electromagnetic wave transmitting section in the predetermined direction by the secondary electromagnetic wave receiving section (3) and / or the primary electromagnetic wave transmitting section (1). The combination of the method of the primary electromagnetic wave transmission unit (1) and the combination of the secondary and primary transmission units (2) is possible other than this example.

FIG. 1 is a block diagram of the system unit.

[0009]

As described above, according to the electromagnetic wave response identification system device of the present invention, the identification signal provided on the object to be identified does not require high precision because it does not depend on the conventional fine optical method. In addition, it is possible to easily and inexpensively identify a variety of objects to be identified by printing with an ink containing a specific substance instead of a device having a circuit for receiving and transmitting electromagnetic waves. In particular, by combining several kinds of secondary electromagnetic waves, the presence or absence of transmission of these secondary electromagnetic waves is suitable for remote identification, and a great deal of development is expected in fields that were relatively restricted in the past.
