The present invention relates to an RFID reader having multiple antennas, and more particularly, to an RFID reader having multiple antennas capable of identifying RFID tag information received through multiple antennas using one RFID reader. It is about.
In general, RFID (Radio Frequency Identification) is an automatic recognition technology using a radio frequency refers to a wireless communication technology that reads or records information of a tag in a non-contact state through an antenna using a radio frequency.
An example of using such an RFID is an RFID reader, which includes an antenna for receiving RFID tag information and an RFID engine unit for identifying RFID tag information received through the antenna.
In particular, the conventional contact RFID reader is composed of an antenna for receiving the RFID tag information and the RFID engine unit for identifying it integrally.
Therefore, no matter how close the contact RFID reader is used, each antenna and the RFID engine unit are inevitably used.
Such RFID readers are widely used in various places and fields such as subway gates (aka 'gates'), large discount counters, airport customs, libraries, etc. It is uneconomical to install the RFID reader equipped with the engine unit integrally.
This is because about 90% of the production cost of the RFID reader is in the RFID engine department.
In addition, since the existing RFID reader and server are connected by wire, complex wire construction is required to apply such a system to an existing building.
Accordingly, an object of the present invention is to solve the above problems, and an object of the present invention is to provide an RFID reader with multiple antennas, which has a structure that can drastically reduce manufacturing costs by arranging and using several antennas in one RFID engine. To provide.
Another object of the present invention is to provide an RFID reader having multiple antennas having a structure capable of identifying which antenna receives RFID tag information received through a plurality of antennas.
Still another object of the present invention is to provide an RFID reader that is easy to install since the RFID tag information is wirelessly transmitted and received to the server.
The present invention for achieving the above object;
An antenna unit comprising a plurality of antennas for receiving RFID tag information wirelessly transmitted from the RFID tag; A switching unit for sequentially identifying a plurality of antennas constituting the antenna unit and receiving the RFID tag information; Sending / receiving information received from the RFID engine unit and the RFID engine unit to the second wireless transmitting and receiving unit of the server by wirelessly identifying the unique information of the RFID tag received by the switching unit and the antenna information received the unique information of the RFID tag It is a basic feature of the first radio transmitter and receiver.
Hereinafter, the features will be understood by the embodiments described in detail with reference to the accompanying drawings attached to the RFID reader having a multi-antenna according to the present invention.
At this time, Figure 1 is a circuit configuration of the RF ID reader having a multi-antenna according to the present invention, Figure 2 is a system configuration diagram provided with an RF ID reader having a multi-antenna according to the present invention.
First, according to FIG. 1, the
In this case, the
The
In more detail, the antenna unit emits radio waves oscillated by the
Such a plurality of antennas (ANT1 ~ ANT8) sequentially radiates the radio waves generated by the
In addition, the
On the other hand, Figure 2 is a system configuration diagram having an
At this time, the
Such a system, for example, when installed in the entrance of the subway, the
Of course, the control of the LCD or LED, which is a display means for expressing a message such as the amount of money or permission to pass when a subway user moves, it is natural that the
In this case, the antennas ANT1 to ANT8 may install only the antennas ANT1 to ANT5 in the case of five entrances according to the characteristics of the installation place.
Hereinafter, an operation process of an RF ID reader having a multiple antenna according to the present invention will be described with reference to FIGS. 1 and 2.
When the
As such, when the unique information of the
In this case, the
Therefore, the
Although the preferred embodiment of the present invention has been described above, the scope of the present invention is not limited thereto, and the scope of the present invention extends to the scope of the present invention to be substantially equivalent to the embodiment of the present invention. Various modifications can be made by those skilled in the art without departing from the scope of the present invention.
As described above, according to the present invention, by arranging and using a plurality of antennas (ANT1 to ANT8) in one
In addition, since the RFID tag information is transmitted and received to the server wirelessly to the RFID engine, it is possible to pursue the ease of installation.
