Description

Technical Field

[0001] This utility model relates to the technical field of RFID box-type desktop scanning equipment, specifically a box-type desktop scanning equipment based on RFID technology. Background Technology

[0002] RFID (Radio Frequency Identification) technology is a type of automatic identification technology that uses wireless radio frequency for non-contact two-way data communication. It reads and writes RFID electronic tags using wireless radio frequency to achieve the purpose of identifying targets and exchanging data. RFID box-type desktop scanning equipment is a desktop scanning device that uses RFID technology as its main component and IO controllers and industrial control host computers as auxiliary components. With the widespread application of RFID technology, various scanning devices with RFID technology as their core technology are being used in more and more scenarios. Among them, desktop equipment is the leader because it has significant advantages such as rapid deployment and low cost.

[0003] Most desktop scanning devices on the market are single-item scanners, capable of scanning a limited number of items (less than 10). When scanning entire boxes of goods, two problems arise.

[0004] First: The quantity is too large, so the RFID signal transmission power needs to be increased. This will cause the RFID to read surrounding products, resulting in misreading and cross-reading.

[0005] Second: The RFID transmission power is too low, which makes it impossible to scan the entire box of products completely, resulting in missed readings.

[0006] To address this, a box-type desktop scanning device based on RFID technology is proposed. Utility Model Content

[0007] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0008] Therefore, the technical solution adopted by this utility model is as follows:

[0009] A box-type desktop scanning device based on RFID technology includes a main body and an auxiliary body. The main body includes a metal housing, an RFID reader / writer located in the middle of the inner cavity of the metal housing, an IO controller located in the middle of the inner cavity of the metal housing and close to the RFID reader / writer, an RFID antenna located on the side of the inner cavity of the metal housing, a wooden panel for covering the inner cavity of the metal housing, and a scanning button located on the outer surface of the metal housing. The auxiliary body includes an industrial control host computer electrically connected to the internal components of the metal housing, a speaker located on the side wall of the industrial control host computer, and an industrial power adapter installed inside the industrial control host computer.

[0010] Preferably, the height of the metal casing is in the range of 15-28 cm.

[0011] Preferably, there are two scanning buttons, both of which are electrically connected to the IO controller.

[0012] Preferably, the number of RFID antennas is four, and the four RFID antennas are evenly distributed at the four corners of the inner cavity of the metal shell.

[0013] Preferably, the maximum adjustment angle of the RFID antenna is 30°.

[0014] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0015] In this invention, a metal casing is used to block RFID signals, preventing misreading and cross-reading. The wooden panel does not block the signal, and the read / write position is set on the wooden panel, enabling large-scale and rapid read / write. Furthermore, four RFID antennas are set at the four corners of the metal casing, so that the signal is reflected by the metal casing and finally concentrated at the center of the wooden panel, further ensuring the function of reading up to one hundred RFID electronic tags and improving the practicality of the device.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0022] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a box-type desktop scanning device based on RFID technology.

[0023] Example 1:

[0024] Combination Figure 1 and Figure 2 As shown, this utility model provides a box-type desktop scanning device based on RFID technology, including a main body and auxiliary mechanisms. The main body includes a metal housing 110, an RFID reader / writer 120 disposed in the middle of the inner cavity of the metal housing 110, an IO controller 130 located in the middle of the inner cavity of the metal housing 110 and close to the RFID reader / writer 120, an RFID antenna 140 disposed on the side of the inner cavity of the metal housing 110, a wooden panel 150 for covering the inner cavity of the metal housing 110, and a scanning button 160 disposed on the outer surface of the metal housing 110. The height range is 15-28CM. There are four RFID antennas 140, which are evenly distributed in the four corners of the inner cavity of the metal housing 110. The maximum adjustment angle of the RFID antennas 140 is 30°. There are two scanning buttons 160, which are electrically connected to the IO controller 130. The auxiliary mechanism includes an industrial control host computer 210 electrically connected to the internal components of the metal housing 110, a speaker 220 set on the side wall of the industrial control host computer 210, and an industrial power adapter 230 installed inside the industrial control host computer 210.

[0025] Specifically, the metal casing 110 is used to block RFID signals and eliminate external interference. At the same time, the wooden panel 150 on the top does not block RFID signals, so reading and writing can be performed through the top. Furthermore, the wood properties of the wooden panel 150 make it more wear-resistant and durable.

[0026] In addition, the height range of the metal casing 110 is set between 15-28cm, which can effectively meet the current usage scenarios. When the metal casing 110 is lower than 15cm, misreading and misreading will occur, while when it is higher than 25cm, the weight will increase too much, making it very troublesome to move.

[0027] The working principle and usage process of this utility model are as follows: First, adjust the angle of the RFID antenna 140 according to the actual scene. The maximum adjustment angle is 30°. After adjustment, cover the wooden panel 150, place the RFID electronic tag to be scanned on the wooden panel 150, and press one of the scanning buttons 160 on both sides of the metal housing 110 to start scanning. After scanning, it can be broadcast through the speaker 220 or directly recorded and the next scan can begin. Finally, the device can be inspected and maintained regularly.

[0028] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
