We have all purchased product that the checkout clerk had to pass over a special electronic pad before they placed the item into the bag.我們都購買了產品,結帳員必須通過一個特殊的電子墊放在面前,他們的項目入包裡。
Why did the clerk have to do that?為什麼辦事員必須這樣做嗎?
Chances are, they were deactivating an electronic device attached to, or hidden within, the product you purchased.機遇是,他們被關閉電子設備重視,或隱藏在,你的產品購買。
Source tagging is the process of adding a small electronic device to a product in order to deter shrinkage (theft).來源標記的過程中增加一個小型電子器件的產品,以阻止收縮(盜竊) 。 The device sets off a store alarm if it is not deactivated at the time of checkout.該裝置集了商店報警如果不能停用的時候結帳。
To everyone but would-be thieves, source tagging creates a win-win-win situation: the devices allow retailers to focus on honest customers instead of worrying about shoplifters; product manufacturers are being provided more shelf space for items that are normally considered high shrink; and customers are able to handle product that is normally stowed out of sight.每個人,但將成為小偷,源標籤創造一個雙贏的局面:在設備允許零售商將重點放在客戶而不是誠實的擔憂商店扒手;產品製造商正在提供更多的貨架空間的項目,通常認為是高萎縮;和客戶能夠處理的產品,通常是存放消失在視線之外。 The benefits so far outweigh any negatives that industry experts expect more and more product to contain these devices.這樣的好處遠遠大於任何底片,工業專家預計,越來越多的產品包含這些設備。
But who will apply these devices?但誰將適用於這些設備? Most retailers want the tags to be applied during the manufacturing or packaging process instead of at the retail level.大多數零售商想要的標籤,以適用於在生產或包裝過程而不是在零售層面。 Not only does it eliminate the possibility of employee tampering but it also makes the process of stocking shelves more efficient.它不僅消除的可能性員工篡改但它也使儲存過程中更有效率的貨架。
RFID Packaging Primer RFID的包裝物
August 15, 2008 08年8月十五日
In the simplest terms an RFID packaging system consists of a tag (transponder) and a reader (interrogator).最簡單的術語包裝的RFID系統由標籤(轉發器)和讀者(審訊) 。
The technology of RFID packaging deals with the remote collection of information stored on a tag using radio frequency communications.該技術的RFID包裝處理遠程收集的信息存儲在標籤上使用無線電頻率通信。 The information stored on the tag can range from as little as an identification number, to kilo-bytes of data written to and read from the tag, to dynamic information maintained on the tag, such as temperature histories.信息存儲在標籤上可以從只有一個身份證號碼,以千字節的數據寫入和讀取的標籤,以保持動態信息的標籤,如溫度的歷史。 The information from the tag/reader combination is either presented to a human operator typically using a hand-held device with a alpha-numeric display or a host computer which automatically manages the information.該信息的標籤/閱讀器組合是不是提交給一個人的運營商通常使用的手持設備與字母數字顯示器或主機電腦自動管理的信息。
Frequency 頻率
Critical performance variables in an RFID packaging system involve the range at which communication can be maintained, the size of the information space contained on the tag, the rate at which the communication with the tag can take place, the physical size of the tag, the ability of the system to “simultaneously” communication with multiple tags, and the robustness of the communication with respect to interference due to material in the path between the reader and the tag.關鍵業績變數的RFID包裝系統涉及的範圍上的溝通才能維持,大小的信息空間上所載的標記,這一比率在這次會議上交流的標記可以進行,物理大小的標記,則能力系統“同時”通信與多個標籤,並在穩健的通信方面的干擾由於材料間的路徑讀取器和標籤。 Several factors determine the level of performance that can be achieved in these variable.有幾個因素確定的性能水平,可以實現在這些變數。 The factors include the legal/regulatory emission levels allowed in the country of use, whether or not a battery is included in the tag to assist its communication back to the reader, and the frequency of the RF carrier used to transport the information between the tag and the reader.的因素包括:法律/監管的排放水平允許在該國使用,而不論是否電池已被列入標記,以協助其通訊回到讀者,和頻率的射頻載波用來運輸之間的信息標籤和讀者。
Over the course of decades of RFID package development, industry has evolved RFID packaging solutions that variously trade the regulatory constraints, the signal propagation characteristics of various RF carrier frequencies, and the economics of tag size and optional batteries.在過去的幾十年的RFID封裝的發展,工業已演變的RFID包裝解決方案,不同的貿易管制的限制,信號傳播特性的各種射頻載波頻率,而經濟學的標籤大小和可選的電池。 These solutions employ only a few RF frequencies around which the vast majority of RFID systems are fielded today.這些解決方案採用只有少數RF頻率圍繞著絕大多數的RFID系統是派出了今天。 The RF frequencies include relatively narrow bands centered at: 125/134KHz or low frequency (LF) 13.56MHz or high frequency (HF) 433/869/915MHz or ultra-high frequency (UHF) 2.45/5.8GHz or micro-wave (uW).射頻頻率包括相對狹窄帶為中心,網址是: 125/134KHz或低頻( LF ) 13.56或高頻( HF ) 433/869/915MHz或超高頻( UHF ) 2.45/5.8GHz或微型波(威斯康星) 。
These frequency values are commonly referred to the RFID packaging technology.這些頻率值通常被稱為的RFID封裝技術。 Thus, tags and readers combinations are described as employing LF, HF, UHF, or uW technology.因此,標籤和讀取器的組合被稱為用人低頻,高頻,超高頻,或威斯康星大學的技術。
Passive/Active Tags 無源/有源標籤
Within any one technology there is a wide variety in tag performance reflecting semiconductor chip performance, tag antenna size and efficiency, and whether a battery is included in the tag.在任何一個技術有各種各樣的標記業績反映半導體芯片的性能,標籤天線尺寸和效率,以及是否電池已被列入標記。 There are two broad classes of tags with respect to the source of energy used to power the tags: passive tags or those that receive their energy solely from the RF field supplied by the reader, or active tags that have a battery to boost the read range of the tag.有兩大類的標籤方面的能源用於電力的標籤:無源標籤或那些接受它們的能源完全由射頻場提供的讀者,或主動標籤,有一個電池,以提高閱讀範圍的標記。
Read Range 讀取範圍
In many cases there is a sharp delineation between the read range of two classes of tags employing passive technology, those that have a relatively short read range and those that have a relatively long read range, especially at LF and HE Like many radio systems, short range RFID systems tend to be less expensive and relatively easy to design and build.在許多情況下,有一個鮮明的劃定範圍改為兩班的標籤採用無源技術,那些相對較短的閱讀範圍和那些相對較長的讀取距離,尤其是在低頻和何象許多無線電系統,短RFID系統的範圍往往是費用較低,比較容易設計和建造。 Long range RFID packaging systems tend to be more expensive and difficult to build.遠距離RFID的包裝系統往往是較為昂貴,而且很難建立。 Typically, the range performance of RFID packagin systems is determined to a major extent by the reader, the power of the signal it radiates and the sensitivity of its receiver.通常情況下,各種性能的RFID packagin系統確定的重大程度上受到讀者的力量它的信號輻射和靈敏度的接收器。
Anti-Collision 防撞
In many applications it is desirable to communicate with a tag when other similar tags are simultaneously visible to the reader.在許多應用中是可取的溝通標籤時其他類似的標記,同時可見的讀者。 In the case of tagging pigs, it is unlikely two pigs will need to be in the read space at the same time.對於標註豬,也不可能兩個豬將需要在閱讀空間同一時間舉行。 In the case of library books an important design feature is the ability to read and “check-out” multiple books as the same time.在圖書的一個重要設計特點是能夠讀取和“退房”多本書的同一時間。 The ability of the tag/reader system to talk unambiguously with one tag at a time is determined by the anti-collision algorithm used to identify each tag and establish a communication session with the tag.的能力,標籤/閱讀器系統,以毫不含糊地談論同一個標籤上的時間是確定的防碰撞算法用來確定每個標籤和建立一個溝通會議的標記。
Tag/Reader Communication Protocols 標籤/閱讀器的通信協議
How information is communicated to and from the tag has historically been determined by the original designer of the semiconductor device in the tag.如何傳達信息,並從標籤歷來是確定的原始設計的半導體器件中的標記。 These protocols vary widely in the ways the carrier is modulated, the data is encoded, read, write, verify commands are structured, how multiple tags are read without interfering with one another, and whether privacy or security services are provided.這些協議有很大差異的,承運人的方式調製,數據編碼,讀,寫,核實命令的結構,如何多個標籤是只讀不干預彼此,以及是否隱私或安全提供服務。 These varying protocols have relative advantages and disadvantages, depending upon the application being considered.這些不同的協議有相對優勢和劣勢,根據申請正在審議中。
Standards 標準
Over time RFID manufacturers and users have typically concluded that while there are advantages to having several communication protocols from which to choose for any application, there would at each frequency be an advantage to settling on one protocol, or at most a couple of protocols, which multiple suppliers could offer chips and readers.隨著時間的推移, RFID的製造商和用戶通常都得出結論說,儘管有優勢,有幾個通訊協議可供選擇的任何申請,將在每個頻率的優勢來解決的一個協議,或最多一對夫婦的議定書,這多個供應商可以提供芯片和閱讀器。
The appearance of these standards is relatively recent and reflects the work of industry bodies including the UCC and the EAN, the International Standard Organization ISO, and national bodies like ANSI in the US Many of these standards are new or are in the process of being defined and there is considerable uncertainty what their form will ultimately be.出現的這些標準是比較近期的,反映了工作的行業機構,包括統一編碼委員會和國際物品編碼,國際標準化組織國際標準化組織,機構和國家機構一樣的ANSI在美國的許多這些標準是新的或正在被界定有相當大的不確定性是其形式將最終。
Summary 綜述
The RFID industry today represents a dynamic attempt by manufacturers and users to build and deploy solutions reflecting trade-offs between a wide range of technical, political, and regulatory constraints. RFID產業的今天是一個動態的企圖製造商和用戶建立和部署解決方案的反映之間的權衡了廣泛的技術,政治和管理上的限制。 It is in this dynamic environment that SAMSys provides RFID readers which enable end-users, system integrators, and automatic data capture (ADC) equipment suppliers to make timely and safe decisions about how to employ RFID.正是在這個不斷變化的環境, SAMSys公司提供RFID讀取器,使最終用戶,系統集成,自動數據採集( ADC )的設備供應商作出及時和安全的決定如何運用RFID技術。
