UHF RFID tag reader with aiming function

An UHF radio frequency identification tag reader with aiming function, especially a wireless radio frequency antenna with a aiming portion, which achieves a high aiming function for quickly aiming a radio frequency identification tag to be read Frequency radio frequency identification tag reader.

Radio Frequency Identification (RFID) is a common non-contact wireless communication technology. It is implemented by at least one RFID reader and a plurality of RFID tags. The composition, because of its high data security, reusability, good penetrability, fast reading speed, etc., has gradually replaced traditional barcode recognition, and has been widely used in daily life, such as medical, logistics, and identity. Identification, transportation, military, library, store, monitoring, etc. can be seen; please refer to "1", which is a conventional UHF RFID tag reader 10, as shown in the figure The frequency band of the applied radio frequency antenna is 865~960Mhz, and the effective sensing distance It can be about 1~10 meters. The application is mainly to lengthen the sensing distance for easy operation and use. However, since the radio wave transmitted by the radio frequency antenna is a directional wave, in the long-distance sensing process, The farther the radio wave is from the radio frequency antenna, the more serious the narrowing is. Therefore, if the user cannot align the radio frequency antenna to the radio frequency identification tag 11 to be sensed at a long distance, the remote sensing is often not detected. In the case of the radio frequency identification tag 11, it is common for a user to continuously change the position of the UHF radio frequency identification tag reader 10 during the operation, which is often caused by an overall operation. Inconvenience, in addition, the process of continuously emitting radio wave induction is also easy to cause the power of the UHF RFID tag reader 10 to be quickly exhausted.

In view of the above problems and needs, the creator has analyzed and studied the structural design of the conventional UHF RFID tag reader based on years of experience in related design, and can design and solve the above problems. Therefore, the main purpose of this creation is to provide an UHF RFID tag reader with an aiming function that can quickly and accurately read radio frequency identification tags and save power loss.

For the above purposes, the UHF RFID tag reader with aiming function is composed of a radio frequency antenna and a control. The wireless radio frequency antenna is assembled at the front end of the controller, and the physical appearance of the radio frequency antenna is formed with a targeting portion; that is, when a user wants to use the aiming When the function UHF RFID tag reader reads a radio frequency identification tag at the far end, the user can first visually align the sight of the radio frequency antenna with the eye, and make the line of sight, the aiming part and the radio frequency The identification tag forms a straight line, and then the controller activates the radio frequency antenna to emit a radio wave, so that the fast aiming and accurate sensing can be achieved, thereby improving the conventional UHF RFID tag reader cannot be quickly aligned. The problem of the radio frequency identification tag; in addition, after aiming at the radio frequency identification tag, the reading operation can also make the power be effectively used to save power.

Please refer to "Figure 2", which is a three-dimensional appearance of the creation. As shown in the figure, the UHF RFID tag reader 20 with aiming function is mainly used in this creation. The radio frequency antenna 202 is formed by a controller 201 and a radio frequency antenna 202. The radio frequency antenna 202 is formed with a targeting portion 2021 and is formed into a circular through hole shape. For example, the aiming portion 2021 can be formed into other types, such as a cross hole, a diamond hole, etc., and is not limited thereto. Referring to the figure, the radio frequency antenna 202 is shown. The system is disposed at one end of the controller 201 and is electrically and electrically connected to the controller 201. Referring to the figure, the controller 201 has a display screen 2014 and one or more operations. The key 2016 can be used by the user to operate and view the information. When a user operates the controller 201, the radio frequency antenna 202 can be driven to transmit a radio wave, and then to a remote radio frequency. Identify the label for sensing; The shape of the radio frequency antenna 202 is mainly optimized for circular applications, but may be formed into a polygonal shape or an irregular shape.

Please refer to "Figure 3", which shows the electrical composition of the creation. For the schematic diagram, please refer to "Figure 4". As shown in the figure, the UHF RFID tag reader 20 with aiming function is mainly composed of the controller 201 and the radio frequency antenna 202, and the controller 201 Further, there is a microprocessor unit 2011, an RF signal processor unit 2012, a memory module 2013, a display screen 2014, a power module 2015, an operation button 2016, and a directional light-emitting element 2017, wherein The radio frequency antenna 202 and the radio frequency signal processor unit 2012 are electrically coupled, and further, the radio frequency signal processor unit 2012, the memory module 2013, the display screen 2014, the power module 2015, the operation keys 2016, and the directional light-emitting elements. 2017, electrically coupled to the microprocessor unit 2011, respectively, the radio frequency antenna 202 is used for transmitting and receiving radio waves (transmitting radio waves S1, receiving the identification signal S2), and the radio frequency signal processor unit 2012 is used to actuate the radio frequency The antenna 202 transmits radio waves, and the power module 2015 provides the power required by each module.
