The basic configuration of the system is RFID, and the memory capacity is only one bit, that is, on or off. The system consists of an RFID tag attached to the object and a scanner at the exit. The RFID tag is activated at the time of installation. When the RFID tag is in the startup state, the proximity of the scanner will be detected. This will generate a warning notice, but the general shopping mall is wide-ranging, and the detection signals of the RFID terminal are mostly fixed. The frequency is searched, and the range that the fixed frequency can search has certain limits. Therefore, it is difficult to determine whether the item exists or not when it is out of the search range. Even if the item is lost, it is impossible to use the rfm system before. As a management and chasing %, in terms of item management, there are still technical deficiencies, and / 2 = two \ 'problems 'for'. Being able to take care of the product's anti-lost device, =2 M3 3 3 624 [New content] In view of this, the purpose of this creation is to use a switchable power signal receiver to expand the scope of item search, thereby improving the efficiency of managing items. . The reason is that, in order to achieve the above object, the RFID-incorporated article anti-lost device comprises at least one radio frequency (RFID) tag, a computerized database and a reader. Each RFID tag is disposed in a package of any item or article, and the RFID tag records a digital code corresponding to one of the configured items, and the computerized database stores the digital code corresponding to each RFID tag ( Code) and an item information. The reader has a signal reader, an antenna and a switching module. The signal reading circuit is configured to transmit an RFID tag through the antenna, and adjust the power of the RF signal through the switching module to detect the RFID tag at different distances. . As described above, the RFID-based item anti-lost device according to the creation is characterized by the use of a radio frequency (RFID) terminal that can switch power to expand the item search range with different powers to confirm whether the item is lost. In order to give your reviewers a better understanding and understanding of the technical features of the creation and the efficiencies achieved, please refer to the preferred examples and the detailed descriptions below. [Embodiment] Hereinafter, an RFID-compliant article anti-lost device according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings. For the sake of understanding, the same components in the following embodiments are denoted by the same reference numerals. Please refer to FIG. 1 , which is a block diagram of the RFID-resistant article anti-lost device of the present invention. In the figure, the RFID-incorporated anti-lost device of the present invention comprises at least one RFID tag 11, a computerized capital M3 3 3 624 library 12 and a reader 13. Each RFID tag u is disposed in any of the articles 10 or the package of the article 10, and the RFID tag n records a digital code (c〇de) lH corresponding to the configured article, wherein the RFID tag 11 is a good one. Band label for readers of different frequencies. In addition, the RFID tag 11 can be active, passive or semi-active according to the modulation mode. The active RFID tag can use its own RF energy to transmit data to the reader, while the passive RFID tag and the semi-active RFID. The tag uses the carrier of the reader to modulate its own signal to transmit data in a modulated φ scattering manner. Although the semi-active tag itself has a battery, it only provides the digital circuit inside the RFID tag. When the reader's energy field is activated, the data is transmitted through the backscatter modulation mode. The computerized database 12 stores a code ll 1 and an item information 121 corresponding to each RFID tag 11 . The reader device includes a signal reading circuit 14, an antenna 15 and a switching module 16, wherein the sfl number reading circuit 14 transmits and receives a wireless RF signal 151 through the antenna 15 to detect the RFID tag 11 and switch through the switch. The module 16 adjusts the power of the RF signal 151 to detect the rFID tag u at different distances. • The above-mentioned digital code (eode) lll can be one of the item 1 product electronic code (EPC), which consists of a header, a general manager code, an object category ^. and a serial number. The header is the first part of the EPC code. It mainly defines the length of the EPC code, the type of identification, and the coding structure of the label. The general manager code has unique characteristics, is an organization code, is also a company code, and is responsible for maintaining the last structure. Two sets of consecutive numbers, the role of the object category code in the EPC coding structure is the form and class of the identified object, and also has unique characteristics, as well as the serial number, which is a continuous number also has a single characteristic, giving objects in the object category The last layer makes the same object distinguish between different individuals. M3 3 3 624 In addition, the reader 13 can integrate different protocols into a reader module and include an alarm system. When the RFID signal of the item 10 does not respond, an alarm can be issued to remind and pay attention to whether the item is Lost. Please refer to FIG. 2, which is a schematic diagram of a preferred embodiment of the RFID-resistant article anti-lost device. In the figure, the RFID-incorporated article anti-lost device of the present invention has a database 22, a reader 23, an antenna 25 and a changeover switch 26. The article 201, the article 202, the article 2〇1, the article 2〇2, and the article 2〇3 are respectively provided with an RFID tag 211, an RFID tag 212, an RFID tag 213, an RFID tag 214, and an RFID tag 215, respectively, when the user is in a space. When searching for the item 201, the item 202, the item 203, the item 204, and the item 205, the search signal of different powers can be generated by the switch 26 by the switch 26, and the item 20, the item 203, the item 204, and the item 204 can be tracked. Item 205, wherein 'switching switch 26 can be controlled by human to determine antenna 25; power, the greater the power, the wider the range searched. The reader 23 is configured to receive the wireless signals of the RFID tag 211, the RFID tag 212, the RFID tag 213, the RFID tag 214, and the RnD tag 215 of the article 201, the article 202, the article 203, the article 2〇2, and the article 2〇3. When the reader 23 starts searching for the item 2〇1, item 2〇2, item 8 1 212, lamp 1〇 tag 213, 叩11) tag 214, and 1^11) the wireless signal labeled '215, the database 22 receives only the wireless signals of the rfid tag 2U, the rfid 2 tag 413, the RFID tag 214, and the RFID tag 215. At this time, the database 22 can send a response message indicating the item 2〇1, the item 203, the item 204, and the item 205. There is a search range, and the location where the item 2〇1, the item 2〇3, the item 2〇4, and the item 205 exist can be known through the search range of different powers. On the other hand, when the reader 22 switches the RFID tag 211 of the device 1, the item 2〇2, and the item 2〇3, and the RFID tag M3 3 3 624 has power, the reader 23 cannot receive the RFID tag of the item 202. At the moment of the wireless signal of 212, the reader 23 sends a warning signal to remind the user to see if the item 202 is lost or is only obscured by other objects and cannot obtain its wireless signal. The database 26 stores related information of the article 201, the article 202, the article 203, the article 204, and the article 205, and can record the location information of the related article. The above is intended to be illustrative only and not limiting. Any changes or modifications that are made without departing from the spirit and scope of this creation shall be included in the scope of the appended patent application.
