[0001]

BACKGROUND OF THE INVENTION The disclosed technology relates to a conventional RFID card which is easy to carry, can record information and can be updated in a non-contact manner, adds a diffusion type infrared technology, and uses a data logger via a gateway to perform ID at a short distance. It belongs to the technical field of a system with high security accuracy that performs a detection function and a detection function of presence or absence of a person or an object in a vast space.

[0002]

2. Description of the Related Art As is well known, in recent years, ID cards have been widely used in financial institutions, health institutions, research institutions, etc. to perform functions of detecting intrusion, departure, and existence period of such facilities. ing.

[0003] Conventionally, generally used RFI
The D card is of a size that is convenient to carry, and can store received information in an electronic circuit and can be updated by non-contact communication.

The RFIDs are classified into five types, such as an electromagnetic coupling type, an electrostatic coupling type, an electromagnetic floating type, a microwave type, and an optical type, according to a spatial transmission medium type, and are widely used among them. In the electromagnetic induction system, a long wave band (mainly 250 k or less) or a medium wave band (13.56 MHz) is used.
The information transmission / reception communication is performed by using the electromagnetic wave of (1), the coil as an antenna such as an ID tag, and the induced voltage due to the induced magnetic flux of the two coils.

Since the induced voltage for communication is proportional to the strength of the magnetic flux of the antenna and the number of turns of the coil of the ID tag, the communication distance is in units of m, and the amount of information is several kilobytes. The appropriate recording procedure is selected.

[0006] Further, the ID tag can be changed into a card size, a business card size, or a coin type or a stick type in accordance with a system requirement, but in reality, a business card size is used. It is heavily used.

[0007] On the other hand, it is conceivable to employ a diffusion type infrared ray that emits light in a unit of several seconds to several minutes as a tag function. However, in this type of method, the communication distance is greatly increased, and a badge (transmitter) and a reader are used. (Receiver) The distance between the receiver and the receiver becomes longer, or the unilateral entry / exit of the automatic door or the electronic lock is more effective than the individual detection function of the RFID card in the entrance path. Unable to respond, individual ID
There is a disadvantage that the operation corresponding to
ID cards have the disadvantage that it is difficult to respond individually to the entry and exit of a large number of people and things in Elijah.

[0008] In Japan, since the output of radio waves is regulated by the provisions of the Radio Law, cards having a communication distance of several centimeters are increasingly used. Therefore, for the purpose of use, it is mainly used for a simple security function system for detecting a simple entry or exit of a person or an object into a space of a predetermined narrow area at an entrance or an office.

Thus, in the diffusion type infrared technology, a person or an object carrying an ID tag that has entered a reception range of a reader (receiver) is transmitted and received in a very short time of milliseconds to receive the ID tag. Adjustment of automatic door opening / closing time, opening / closing of electronic lock, ON / OFF of lighting by location confirmation within the range, location confirmation when moving, and flow line management
Although it can be applied to a wide range of applications, such as when the reception distance of the reader (receiver) is large, for example, when a large number of people or things enter the reception area at once, the automatic door and electronic lock open and close smoothly. If you enter the room,
When a plurality of IDs are known, there is an inconvenience that it is difficult to control the operation corresponding to each ID.

[0010] Therefore, there is a pressing need to develop a system that operates only in response to a person or an object permitted to an area such as a predetermined room. However, there is a disadvantage that a system corresponding to these has not been devised yet. there were.

Further, there is a disadvantage that a system for performing operation control that satisfies both needs requires a considerably high cost.

[0012]

OBJECTS OF THE INVENTION The object of the invention of this application is to take advantage of the above-mentioned mutually different techniques based on the above-mentioned prior art,
In order to eliminate the disadvantage, the conventional RFID ID tag is improved to provide a detection function by a diffused infrared ray that can reach not only a linear direction at a predetermined distance but also a predetermined bent direction, and furthermore, a specific area. Not only that, even in a narrow area having a passage that passes directly, it is possible to ensure that the arriving infrared rays can function in badges (transmitters) and readers. The hybrid ID is not provided.
