Translated fromChinese技术领域technical field
本发明涉及通信技术领域，尤其涉及一种商品条码与电子标签的转换方法与系统。The invention relates to the field of communication technology, in particular to a method and system for converting commodity barcodes and electronic labels.
背景技术Background technique
条码技术出现于20世纪40年代，因其成本低、采集信息准确率高等特点在各个行业得到了广泛的应用，其中包括物流、仓储，图书馆，银行，pos收银系统，医疗卫生、零售商品、服装、食品服务以及高科技电子产品等等，商品条码为其最具代表性的应用典范，商品条码是实现商业现代化的基础，是商品进入超级市场、POS扫描商店的入场券，它已成为商品进入超市的必备条件。Barcode technology appeared in the 1940s and has been widely used in various industries due to its low cost and high accuracy of information collection, including logistics, warehousing, libraries, banks, POS cash register systems, medical and health care, retail goods, Clothing, food service and high-tech electronic products, etc., commodity barcode is the most representative application model. Commodity barcode is the basis for realizing commercial modernization, and it is the entry ticket for commodities entering supermarkets and POS scanning stores. It has become A necessary condition for goods to enter the supermarket.
EAN商品条形码亦称通用商品条形码，由国际物品编码协会制定，通用于世界各地，是目前国际上使用最广泛的一种商品条形码。而EAN-13商品条码则为其最主要的结构，主要应用于超级市场和其它零售业，因此这种是我们比较常见的，随便拿起身边的一个从超市买来的商品都可以从包装上看得到，是我国在国内推行使用最广泛的商品条形码。条码技术虽然是当今最流行的标识技术，但因其固有的缺陷，不能满足快速、实时、准确的信息采集和处理。现代物流的标准化和高效化已成为了衡量物流的重要指标，这就要求物流企业必须实时和精确地了解、掌握整个物流环节上包括采购、存储、包装、运输、流通加工、配送、销售到服务等等环节中实时的变化和发展。RFID电子标签技术具有可读写能力、快速大批量的数据扫描、抗污染能力和耐久性强、使用寿命长、穿透性无屏障阅读能力强、数据记忆容量大以及安全性高等特点，能够广泛应用在现代物流供应链上的生产管理、运输管理、仓库管理、物料跟踪、运载工具和货架识别、商店等场合。而且其能实现其在现代物流中具有相当重要的的应用价值，也是未来物流行业发展的一个趋势。EAN commodity barcode, also known as universal commodity barcode, is formulated by the International Article Numbering Association and is commonly used all over the world. It is currently the most widely used commodity barcode in the world. The EAN-13 commodity barcode is its most important structure, mainly used in supermarkets and other retail industries, so this is more common for us, and you can pick up a commodity bought from a supermarket around you and you can check it from the package. It can be seen that it is the most widely used commodity bar code in my country. Although barcode technology is the most popular identification technology today, it cannot meet the requirements of fast, real-time and accurate information collection and processing due to its inherent defects. The standardization and efficiency of modern logistics have become an important indicator of logistics, which requires logistics companies to understand and master the entire logistics link in real time and accurately, including procurement, storage, packaging, transportation, circulation processing, distribution, sales and service. Real-time changes and developments in other links. RFID electronic tag technology has the characteristics of readable and writable ability, fast and large-scale data scanning, strong anti-pollution ability and durability, long service life, penetrating barrier-free reading ability, large data memory capacity and high security. Applied in production management, transportation management, warehouse management, material tracking, carrier and shelf identification, stores and other occasions in the modern logistics supply chain. Moreover, it can realize its very important application value in modern logistics, and it is also a trend in the development of the logistics industry in the future.
EPC中文称为产品电子代码。EPC的载体是RFID电子标签，并借助互联网来实现信息的传递。2003年10月国际上成立EPC GLOBLE全球组织推广EPC和物联网的应用。欧、美、日等发达国家在全力推动符合EPC技术电子标签应用，全球最大的零售商美国沃尔玛宣布：从2005年1月份开始，前100名供应商必须在托盘中使用EPC电子标签，2006年必须在产品包装中使用EPC电子标签，我国近几年来的EPC电子标签的发展也日益迅猛，其必然会成为一个发展趋势。EPC is called Product Electronic Code in Chinese. The carrier of EPC is RFID electronic tag, and realizes the transmission of information by means of the Internet. In October 2003, the EPC GLOBLE global organization was established internationally to promote the application of EPC and the Internet of Things. Developed countries such as Europe, the United States, and Japan are making every effort to promote the application of electronic tags that comply with EPC technology. The world's largest retailer, Wal-Mart, announced that starting from January 2005, the top 100 suppliers must use EPC electronic tags in pallets. EPC electronic tags must be used in product packaging. In recent years, the development of EPC electronic tags in my country has become increasingly rapid, and it will inevitably become a development trend.
在零售商品行业中，EPC电子标签应用逐渐普及，其主要采用序列化的全球贸易项目代码(SGTIN)编码结构的EPC电子标签。然而受生产工艺和价格成本所限，还不能广泛应用于标示单个个体。而条码标签具有价格便宜的优势，将两者结合起来应用于商品供应链全过程管理，具有重要的现实意义。在条形码和电子标签共存的环境下，商品流通过程中，采用RFID技术与条码技术结合，来解决电子标签成本和自动数据采集效率之间的矛盾是一条非常合适的途径。在大宗物品上，例如托盘采用电子标签标识，方便出入库管理，在商品单品上，通过后台系统，将电子标签信息转换为条形码，做到单品标识，方便消费者追溯查询。这就需要在电子标签信息和条码信息之间做转换，以保证商品链信息的畅通和追溯与召回的实现。采用电子标签和条码技术应用于商品的标识，对于加强对商品供应链实时监管具有重要意义。In the retail commodity industry, the application of EPC electronic tags is gradually becoming popular, which mainly adopts the EPC electronic tags with serialized global trade item number (SGTIN) coding structure. However, limited by the production process and price cost, it cannot be widely used to mark a single individual. The bar code label has the advantage of being cheap, and it is of great practical significance to combine the two to apply to the whole process management of the commodity supply chain. In the environment where barcodes and electronic tags coexist, in the process of commodity circulation, it is a very suitable way to use the combination of RFID technology and barcode technology to solve the contradiction between the cost of electronic tags and the efficiency of automatic data collection. For bulk items, such as pallets, electronic tags are used to facilitate storage management. On single items, the electronic tag information is converted into barcodes through the background system to achieve single item identification, which is convenient for consumers to trace and query. This requires conversion between electronic label information and barcode information to ensure the smooth flow of commodity chain information and the realization of traceability and recall. The application of electronic label and barcode technology to the identification of commodities is of great significance for strengthening the real-time supervision of commodity supply chains.
综上可知，现有的商品条码，在实际使用上显然存在不便与缺陷，所以有必要加以改进。In summary, the existing commodity bar codes obviously have inconvenience and defects in actual use, so it is necessary to improve them.

a)读取电子标签分区值P＝b84b83b82，若0≤P≤6，继续译码；否则转换停止。a) Read the electronic label partition value P=b84 b83 b82 , if 0≤P≤6, continue decoding; otherwise, the conversion stops.
b)根据表4，获取厂商识别代码的位数M，分离出厂商识别代码部分b81b80...b(82-M)和贸易项代码部分b(81-M)b(80-M)...b38。b) According to Table 4, obtain the number of digits M of the manufacturer identification code, separate the manufacturer identification code part b81 b80 ... b(82-M) and the trade item code part b(81-M) b(80-M ) ...b38 .
c)将厂商识别代码b81b80...b(82-M)当作无符号整数，转换为十进制数表示的L位数字p1p2...pL，提取厂商识别代码。如果L大于12，输入位串是非法的SGTIN-96编码，转换停止；如L等于12、11或者6，则输入位串为不能转换为零售商品条码编码的SGTIN-96编码，转换停止。c) Treat the manufacturer identification code b81 b80 ... b(82-M) as an unsigned integer, convert it into an L-digit number p1 p2 ...pL represented by a decimal number, and extract the manufacturer identification code. If L is greater than 12, the input bit string is an illegal SGTIN-96 encoding, and the conversion stops; as L equals 12, 11 or 6, then the input bit string is an SGTIN-96 encoding that cannot be converted into a retail product barcode, and the conversion stops.
d)将贸易项代码b(81-M)b(80-M)...b38当作无符号整数，转换为十进制数表示的(13-L)位数字i1i2...i(13-L)，提取项目参考代码和指示码。如果(13-L)大于7，则输入位串是非法的SGTIN-96编码，转换停止；如果指示码i1不等于零，则输入位串为不能转换为零售商品条码编码的SGTIN-96编码，转换停止。d) Treat the trade item code b(81-M) b(80-M) ... b38 as an unsigned integer, and convert it to a (13-L) digit i1 i2 ... i represented by a decimal number(13-L) , to extract item reference codes and indicator codes. If (13-L) is greater than 7, then the input bit string is an illegal SGTIN-96 encoding, and the conversion stops; if the indicator code i1 is not equal to zero, then the input bit string is the SGTIN-96 encoding that cannot be converted to retail commodity barcode encoding, Conversion stopped.
e)构造13位数字X13X12...X1，这里X13X12...X(14-L)对应为步骤a)中的p1p2...pL，X(13-L)X(12-L)...X2为步骤b)中的i2i3...i(13-L)。e)
