Description
- This application claims the benefit of U.S. Provisional Application No. 60/872,165, entitled “RFID Systems,” filed on Dec. 1, 2006, which application is incorporated herein by reference.
- The present invention is directed, in general, to reader systems and, in particular, to a modular reader portal and method of forming the same.
- While the core technologies that support radio frequency identification (“RFID”) systems have been around for some time, the applications that drive the use thereof have been slow to market. The aforementioned trend has been turning in an impressive fashion as the size and cost of the RFID tags has decreased and the sensitivity of RFID readers has increased. Moreover, the market forces, especially with respect to the supply chain in the retail industry, are pulling the RFID technologies into the mainstream and literally onto the shelves.
- With respect to the supply chain, portals (e.g., RFID portals) including readers (e.g., RFID readers) are employed to read identification tags (e.g., RFID tags) on boxes and the like as products move from one location to another within the supply chain. During RFID deployments (e.g., hardware installations), it is difficult to properly determine portal configurations to install a fixed RFID portal. For instance, varying sizes are required portal-to-portal and customer-to-customer. Install locations are often changed at the last minute (e.g., customer requirements change), which can make even proper planning and design a challenge at the time of installation. Due to building constraints, the RFID portals may not be anchored to a wall (e.g, metal buildings may not provide sufficient structural support for a wall mount like a concrete wall). Dock leveler equipment may or may not be present (pit levelers may be cut into the floor of the facility), or there may be other obstructions that require some flexibility like dock seals, dock lamps, or trailer safety light panels.
- There are other design flaws of typical RFID portals. For instance, cables are often exposed, which can be damaged or severed by material handling equipment. The assembly holes may be misaligned, or manufacturing defects may occur due to a lack of reference edges. This adds much time for proper assembly onsite and can result in rework time needing to be done onsite.
- The manufacturing lead times on the hardware portals can vary from two to six weeks depending on the workload at the manufacturer sites as well as the design of the portal that is specified. These lead times can cause critical installation schedule problems if the RFID portal designs are not pre-built. An additional challenge with custom portals is that they are more expensive to produce.
- Accordingly, what is needed in the art is a modular reader system including a portal employable in several configurations, preferably using standardized components, that overcomes the deficiencies in the prior art.
- These and other problems are generally solved or circumvented, and technical advantages are generally achieved, by advantageous embodiments of the present invention that include a modular reader portal and method of forming the same. In one embodiment, the modular reader portal includes first and second vertical stanchions including a telescopic segment configured to adjust a height thereof. The modular reader portal also includes a horizontal stanchion including a telescopic segment to provide an adjustable horizontal crossbar between the first and second vertical stanchions. The modular reader portal further includes a reader attached to one of the first and second vertical stanchions and the horizontal stanchion configured to read an identification tag located on a product passing near the modular reader portal.
- In another aspect, the present invention provides a method of forming a modular reader portal. The method includes forming first and second vertical stanchions with a telescopic segment configured to adjust a height thereof. The method also includes forming a horizontal stanchion with a telescopic segment to provide an adjustable horizontal crossbar between the first and second vertical stanchions. The method further includes attaching a reader to one of the first and second vertical stanchions and the horizontal stanchion configured to read an identification tag located on a product passing near the modular reader portal.
- The foregoing has outlined rather broadly the features and technical advantages of the present invention in order that the detailed description of the invention that follows may be better understood. Additional features and advantages of the invention will be described hereinafter which form the subject of the claims of the invention. It should be appreciated by those skilled in the art that the conception and specific embodiment disclosed may be readily utilized as a basis for modifying or designing other structures or processes for carrying out the same purposes of the present invention. It should also be realized by those skilled in the art that such equivalent constructions do not depart from the spirit and scope of the invention as set forth in the appended claims.
- For a more complete understanding of the present invention, and the advantages thereof, reference is now made to the following descriptions taken in conjunction with the accompanying drawings, in which:
-
FIG. 1 illustrates a system level diagram of an embodiment of an RFID system constructed according to the principles of the present invention; -
FIG. 2 illustrates a block diagram of an embodiment of an RFID tag constructed according to the principles of the present invention; and -
FIGS. 3 to 7 illustrate diagrams of portions of modular reader portals constructed according to the principles of the present invention. - The making and using of the presently preferred embodiments are discussed in detail below. It should be appreciated, however, that the present invention provides many applicable inventive concepts that can be embodied in a wide variety of specific contexts. The specific embodiments discussed are merely illustrative of specific ways to make and use the invention, and do not limit the scope of the invention. Unless otherwise provided, like designators for devices employed in different embodiments illustrated and described herein do not necessarily mean that the similarly designated devices are constructed in the same manner or operate in the same way. The present invention will be described with respect to an exemplary embodiment in a specific context, namely, an RFID system including an RFID portal that is not only rugged, but is also flexibly used in a number of install configurations to ease assembly and installation as well as reduce costs and manufacturing lead times. While the exemplary embodiments are described with respect to an RFID system and portal, those skilled in the art should understand that the principles of the present invention are applicable to any reader system and modular reader portal including, without limitation, bar code readers and optical readers.
- In an exemplary embodiment, the RFID portal is developed for speed of assembly and ease of installation while retaining critical strength and lighter weight, lowering costs. For visual safety, the RFID portal may be powder coated or painted a safety color (e.g., yellow). The RFID portal components are preferably standardized for flexible use in multiple scenarios. An embodiment of the RFID portal is set forth below. Those skilled in the art, however, understand that the RFID system may employ other modular portal configurations and still fall within the broad scope of the present invention.

FIG. 1 , illustrated is a system level diagram of an embodiment of an RFID system constructed according to the principles of the present invention. The RFID system includes aserver 110, acomputer system 120, and anRFID portal 125 including anRFID reader 130 located on abackplane mounting plate 135 with antennas (designated 140). The computer system 120 (in connection with the server 110) directs theRFID reader 130 to read RFID tag(s) 150 located on a product orhost material 160. TheRFID portal 125 includes first and secondvertical stanchions RFID portal 125 also includes ahorizontal stanchion 180 formed from telescopic segments to form an adjustable horizontal crossbar between the first and secondvertical stanchions vertical stanchions mount plate footings 190 at a base thereof. - While a
single product 160 is illustrated herein, those skilled in the art should understand that the product conceptually may also represent multiple products. In addition, the communication links between respective systems in the RFID system may be wired or wireless communication paths to facilitate the transmission of information therebetween.

More specifically,FIGS. 6A , 6B, 6C, 6D and 6E illustrate a left side view, a top view, a right side view, a bottom view, and a front view, respectively, of the reader enclosure. Additionally,FIG. 7 illustrates a top view of the backplane mounting plate. Of course, the dimensions on the FIGUREs are provided for illustrative purposes only. The reader enclosure illustrated inFIG. 6 provides flexibility in mounting a variety of different components in the same enclosure. As deployment environments may vary, the reader enclosure is adaptable, as is the modular reader portal, to allow for operators to make component changes on site as needed. The backplane mounting plate illustrated inFIG. 7 allows for the reader enclosure ofFIG. 6 to be easily mounted to the backplane, which is assembled to, for instance, a telescopic segment of a horizontal stanchion. The additional benefits for utilizing the reader enclosure are that it permits preassembly and testing prior to arrival on site to expedite the installation process for personnel. Those skilled in the art of modular reader portals understand that the reader enclosure is included as an example and additional embodiments of a reader mounting system for a modular reader portal are well within the broad scope of the present invention. - The readers often utilize external antennas that may be attached to the modular reader portal. Additionally as illustrated in
FIG. 5 , adjustable mounts (designated “AM”) may be used to allow for flexible locations in three dimensions/orientations. The adjustable mounts may also be used for mounting other reader hardware accessories such as a NEMA box for attaching a programmable logic controller (“PLC”) or an input/output (“IO”) device. Again, those skilled in the art understand that the mounts may be used in different ways to accommodate various designs. - Thus, a modular reader portal and method of forming the same has been introduced herein. In one embodiment, the modular reader portal includes first and second vertical stanchions including a sleeve footer stanchion, a sleeve segment, a telescopic segment and a telescopic segment elbow configured to adjust a height thereof. The modular reader portal also includes a mount plate footing at a base of the first and second vertical stanchions. The modular reader portal also includes a horizontal stanchion including a telescopic segment elbow, a telescopic segment and a sleeve segment to provide an adjustable horizontal crossbar between the first and second vertical stanchions. The modular reader portal further includes a reader (e.g., a radio frequency identification reader, a bar code reader and an optical reader) located on a backplane mounting plate and an antenna attached to one of the first and second vertical stanchions and the horizontal stanchion configured to read an identification tag located on a product passing near the modular reader portal. Additionally, the reader is directed to read the identification tag by a computer system. The reader is also enclosed in a reader enclosure. The modular reader portal still further includes adjustable mounts configured to mount the first and second vertical stanchions to one of a floor and a wall.
