RFID智能文件柜RFID smart file cabinet
本实用新型涉及一种文件柜，尤其涉及一种可精确区域定位的RFID智能文件柜。The utility model relates to a file cabinet, in particular to an RFID intelligent file cabinet capable of precise area positioning.
传统文件柜为方便查找通常进行分类按区域进行文件或物品存放，并在每个区域或每个文件上对应位置粘贴标识，这种方式存在如下问题：Traditional file cabinets are usually classified for easy searching, and files or items are stored by area, and the labels are pasted in corresponding areas in each area or each file. This method has the following problems:
(1)文件需按指定位置存放；(1) Documents must be stored in the designated location;
(2)无法实现自动盘存清点，人工盘点费时费力，工作量很大；(2) It is impossible to realize automatic inventory inventory, manual inventory is time-consuming and laborious, and the workload is large;
(3)人工存放不可避免会有差错发生，存放位置和次序打乱后再查找会很困难；(3) Manual storage will inevitably lead to errors, and it will be difficult to find the storage location and order after it is disrupted;
(4)无法实时掌握在库情况，无法准确掌握在库位置；(4) It is impossible to grasp the situation in the library in real time, and it is impossible to accurately grasp the location of the library;
(5)管理效率低，容易出差错，缺乏安全管理手段。(5) Low management efficiency, easy error, and lack of security management tools.
已有基于RFID技术的文件柜，主要分两类：一类是没有定位能力的，在柜内装设的天线有一个或几个，目的是能实现自动盘存功能；另外一类是可精确定位的，类似文件夹的形式，一个柜内由多层此类集成RFID功能的文件夹组成，这种文件柜单柜管理文件数量比较有限一般不超过几百份。There are two kinds of file cabinets based on RFID technology, which are mainly divided into two categories: one is that there is no positioning capability, one or several antennas are installed in the cabinet, the purpose is to realize the automatic inventory function; the other is the precise positioning. In the form of a folder, a cabinet consists of multiple layers of such RFID-enabled folders. The number of files in a single cabinet is generally limited to a few hundred.
效率很低难以提高，对于内部组成为文件夹型式的可精确定位的文件柜，查找效率提升了，但对于大批量文件管理应用场合会大幅度升高成本，需要配备数量可观的文件柜，占用更多的空间。所以有必要研究一种实现精确区域定位功能的文件柜进行大批量文件的高效管理。For the high-efficiency management of large-volume files, the above two types of file cabinets are difficult to meet the requirements, and the file cabinets that can be automatically inventoried but have no positioning capability can be used for file pick-and-place and search.
The efficiency is very low and it is difficult to improve. For the accurately-positionable file cabinet with internal folder type, the search efficiency is improved, but for large-volume file management applications, the cost will be greatly increased, and a considerable number of file cabinets need to be equipped. More space. Therefore, it is necessary to study a file cabinet that implements precise regional positioning function for efficient management of large-volume files.
