Empirical Research on Applicability of RFID System to Large Library

RFID技术是即将到来的普适计算时代的一项核心IT技术。它具有非接触式通信、大内存、免电池等特点。它将用于许多已经提供了磁卡和条带的服务。图书馆是这项技术的一个很有前途的应用领域，因为图书馆的工作，特别是处理资料，既费时又费力。减少盘点时间和柜台数量对图书馆来说将是一个巨大的好处。本研究的目的是探讨RFID系统对大中型图书馆的影响，而RFID标签系统的发展趋势调查是本研究的重要对象。我们走访了国内外图书馆和RFID相关厂商，交流了信息和意见。我们还参观了与射频识别相关的展览，如汽车ID博览会，我们在九州大学图书馆的奇库什分馆安装了射频识别标签系统，并调查了…的效果图书馆工作的ID标签更多。我们首先在大约5,000本书上贴上13.56 MHz的标签，然后再附加2万个ID标签。作为结果，我们知道自助结账机和图书检测系统在操作程序中实际上是有用的，并且与使用条形码扫描仪相比，使用方便的RFID读取器检查书籍大大缩短了检查时间。我们也认识到了一些问题。例如，由于现有的RFID阅读器不足以同时检测多个方向的多个RFID标签，因此无法使用智能书架进行实时盘点，因此我们在一些RFID阅读器制造商的帮助下，研究了具有新的高精度RFID阅读器的智能书架对新的图书馆服务的适用性。我们的实验表明，智能书架足够准确地检测到贴在书架内书籍上的所有RFID标签，即使有些书是倾斜的或水平放置的。此外，当从书架上取出一本书时，我们可以立即发现没有书，因为读者只检测到书架上的标签。当我们在厚度约为6毫米的薄期刊上贴标签时，准确率相当低。然而，当我们交替地在期刊的两个不同位置上贴标签时，准确率正在急剧增加。这种智能书架将使图书馆能够提供新的图书馆服务，例如具有更精确图书位置的OPAC，尽管目前许多图书馆为了节省人力而引入了RFID系统。较少

RFID technology is a core IT technology in the coming ubiquitous computing era. It has great features such as contactless communication, big memory, battery-less and so on. It will be used many services that have been provided with magnetic cards and barcordes. The library is a promising application field for the technology, since the library work, especially dealing with materials, is time- and labor-consuming. Reduction of time for inventory and number of counters will be a great benefit for libraries. The goal of this research is to investigate the effect of the RFID system to middle and large libraries.The trend survey of RFID tag systems is an important object of this research. We have visited domestic and foreign libraries and RFID related makers to exchange of information and opinions. We have also visited RFID related exhibitions, such as AUTO-ID Expo.We have installed a RFID tag system to the Chikushi branch library of Kyushu University Library, and investigated the effect of … More the ID tags to library jobs. We started by attaching 13.56MHz tags to about 5,000 books, and then additional 20 thousand ID tags have attached. As the results we know that self-checkout machines and book detection systems are practically useful with operational procedures, and that checking books with a handy RFID reader reduce drastically checking time compared to time with a barcorde scanner. We have also recognized some problems. For example, real-time inventory is impossible using intelligent bookshelfs, because existing RFID readers are not enough to detect many RFID tags in many orientations simultaneously.So we have investigated the applicability of intelligent bookshelfs with new, highly accurate RFID readers to new library services with the help of some RFID reader maker. Our experiments show that the intelligent bookshelf are accurate enough to detect all RFID tags attached to books within the bookshelf, even if some books are inclined or laid horizontally. Moreover, we can find absence of a book right away when it is taken from the bookshelf, since the readers detect only tags within the bookshelf. When we attach tags to thin periodicals with around 6mm thick, the accuracy is quite low. However, the accuracy is increasing drastically, when we attach tags on two different positions of the periodicals alternately. Such intelligent bookshelves will enable library to provide new library services, such as OPAC with more precise book positions, although currently the RFID system is introduced into many libraries for the sake of laborsaving.
