Application of electronic tags in container recycling

electronic tags (also known as transponder) are the most advanced non-contact induction technology at present. It automatically identifies the target object and obtains relevant data through RF signals. Since 1998, Texas Instruments (TI) of the United States and Philips of the Netherlands announced that they had developed a cheap non-contact induction chip. By 2000, the international organization for standardization had written this non-contact induction chip into the international standard iso15693. At present, many companies around the world are doing research on radio frequency identification (RF ID) technology, and embedding RF ID chips, namely electronic tags, into their products for real-time tracking, promotion and anti-counterfeiting of goods. Intellident is a system integration manufacturer specializing in data tracking using bar codes and smart labels. In the first half of 2004, georgiapa2cfic in Atlanta cooperated with it to test embedding RF ID electronic labels into its corrugated boxes. A Finnish company has also developed an RF ID electronic tag with an antenna attached to a paper package. The application of RF ID technology to logistics management can better ensure the close combination of supply chain management, so as to improve production efficiency and obtain great profits, taking the Class B1 Standard in the new national standard GB8624 ⑵ 012 "classification of flammability of building materials and products" as an example

1 working principle

electronic tag is the carrier of data information, which is usually composed of coupling elements (coil, microwave antenna) and memory and microelectronic chip used to store relevant application identification information. The data information in the information memory should be obtained through the reader. A typical reader/writer includes high-frequency module (transmitter and receiver), control unit and coupling element (antenna). Electronic tags can be divided into active electronic tags and passive electronic tags according to whether there is power on them, and can be divided into read-only tags and read-write tags according to the different types of internal memory. Generally, the electronic tag does not have its own power supply. When it enters the working area of the reader, the antenna receives the specific electromagnetic wave sent by the reader, and the coil on the tag will generate induced current, which will be rectified and charge the capacitor. The capacitor voltage is used as the working voltage after being stabilized. At this time, the chip on the reader or tag completes the data modification and storage functions. The advantage of passive electronic tag is that it has a permanent service life

electronic tag is a non-contact automatic identification technology, which automatically identifies and obtains relevant data through radio frequency signals without manual intervention. Compared with the barcode that quickly and accurately confirms the tracking target object, the advantages of electronic tag are as follows:

1) data can be read through external materials (no visibility requirements)

2) waterproof, antimagnetic, high temperature resistant, can work in poor working environment, and has a long service life

3) can be embedded or attached to different types of products

4) the reading distance range is improved, and there is no need for linear alignment scanning

5) less time to write data and large amount of stored information

6) multiple cards can be read at the same time, and the information on the label in motion can be read

7) ultra thin and various sizes make it can be packaged in paper and plastic products (PVC, PET), which can be used in different occasions, and can also be laminated to press cards. RF ID advocates believe that this technology is closely linked with the electronic supply chain and is expected to replace bar code scanning technology in the next few years

2 acquisition of electronic labels

the printing industry plays an important role in the production of electronic labels. Printing antennas in electronic labels with conductive ink can greatly reduce the production cost of RF ID electronic labels. In the initial stage of the production of electronic labels, the method of printing will be mainly used, but in the end, the method of mass production should be used, such as flexographic printing and gravure printing. The silk printing process used in the manufacture of antenna coils is described below. Using this method, the coil with arbitrary shape can be directly printed on an embedded film. The "printing color" used is the so-called polymer thick film (PTF). It is composed of powder of conductive materials (such as silver, copper, graphite), liquid solvent and artificial resin as reinforcement. After drying, it is embedded into the film to form a printed line of conductive film. The conductivity of the film will decrease after lamination, because the heating and pressurization effects will increase the contact point between the particles of the mixed powder. Connect the printed coil with a chip or a module. The usual welding process is reviewed by the laboratory qualification department. It is invalid for the polymer thick film. One way is to use the flip - chip process, that is, the pressure welding point of the chip without shell is directly placed down on the connection position of the coil and connected through conductive adhesive. At present, printers and electronic ink manufacturers can produce electronic labels with a micro processing capacity of nearly 100bit, which is enough to provide information similar to that provided by bar codes, such as manufacturer, product serial number and batch number

using silk printing technology to obtain the antenna in the electronic label can be produced on a large scale and improve production efficiency. However, due to the difference between the production process of electronic labels and traditional label printing, printing enterprises need large equipment investment, human investment, staff training, and the purchase of corresponding supporting software, development tools, quality control tools, etc. Therefore, the entry threshold is high, which is a challenge. Nevertheless, RF ID electronic label printing enterprises are constantly improving and innovating their processes to minimize the cost of printing and pave the way for the application of RF ID electronic labels

3 application of electronic labels in container recycling

in recent years, electronic labels have been applied in some practical applications, such as process industry logistics management, air parcel management, terminal container management, etc. At present, the source of containers is the containers of container leasing companies, except for the actual carrier's boxes, part of the NVOCC's boxes and the owner's own boxes. The actual carrier can be the owner of the shipping company, train, car and aircraft, and they control these means of transportation. NVOCC is engaged in the collection, packing, unpacking, inland transportation of container freight and the transfer or inland war business in the operation, but does not operate ships. Shipping companies in China's shipping market mainly operate and manage containers in the following three ways:

1) large domestic shipping companies with relatively strong strength usually set up container management departments within the company, which are specially responsible for the recycling and management of containers. For the container recycling and management related businesses, the container management department of the shipping company establishes corresponding legal relations with the outside world in the name of the shipping company, signs the container equipment handover list in the name of the shipping company, and collects the container pressing fee, etc

2) large foreign shipping companies with relatively strong strength usually set up shipping branches in major ports in mainland China, and set up container management departments within the shipping branches to be responsible for container recycling and management. For container recycling and management related businesses, the container management department of the shipping branch establishes corresponding legal relations with the outside world in the name of the shipping branch, signs the container equipment handover list in the name of the shipping branch, and collects container pressing fees. The shipping branch actually acts as the operator and manager of foreign shipping companies' containers in China

3) some domestic shipping companies with less strength or some foreign shipping companies with less strength that do not set up shipping branches in China usually sign container management agreements with domestic shipping companies or shipping agencies, and entrust domestic shipping companies or shipping agencies and other units to be responsible for the recycling and management of containers in China. For the container recycling and management related businesses, the container management departments of domestic shipping or shipping agency companies establish corresponding legal relations with foreign countries in the name of domestic shipping or shipping agency companies, sign the container equipment delivery list in the name of domestic shipping or shipping agency companies, and charge container pressing fees. In fact, domestic shipping companies or shipping agencies also act as the operators and managers of these shipping companies' containers in China

if, according to the theoretical container handover method, each circulation responsible part complies with the original rules, the containers can be recovered in time, but in fact, it is not as we want. There are cases where containers are not recovered in time and cause damage to containers. For example, if the delivery mode of goods is cy - cy, that is, from the carrier's container yard at the loading port to the carrier's container yard at the unloading port. If this provision is strictly followed, the carrier should unpack the container at the container yard at the unloading port, take out the transported goods from the container, and then hand over the goods to the consignee or its entrusted agent. However, in fact, there is often a long distance between the carrier's container yard and the consignee's warehouse. If we completely follow the above operation method mechanically, it will inevitably add a lot of inconvenience to the consignee. According to maritime customs, the carrier or its entrusted container operator or manager usually gives the complete container full of goods to the consignee or its entrusted agent, and the carrier or its entrusted container operator or manager returns the container to the consignee or its entrusted agent for a few days of free use. The consignee or its entrusted agent will transport the goods to the consignee's warehouse, but in order to ensure that the container is returned on time, the carrier or its entrusted container operator or manager must pay the container pressing fee, and issue a container equipment handover list, specifying the free use period and return location. Sometimes the consignee does not return the container to the designated place on time, which causes a lot of inconvenience

the use of electronic tags on containers means that the electronic tag system is used as an important carrier for the electronization of container information, and the detailed information such as the container number, manufacturer, owner, etc. is input into the electronic tag. When the labeled container passes through the reader, the tag will transmit the product data to the reader, and then the reader downloads the data to the reader. These metal surfaces can form a fine oxide film central processor, Generate container management database. In this way, all the processes of the container from delivery to final unloading can be clearly understood and grasped, so that the container cycle is more smooth, which can help the container recycling Department understand the dynamics of the container in time, and keep in touch with the owner or agent or lessee in time. The contact method can be fax or contact, so as to avoid being abandoned due to being unattended for a long time, and effectively improve the utilization rate of the container. If the frequency of labels of several containers is the same as that of the target object, there may be conflict, so there is anti-collision technology. Therefore, in order to obtain the relevant information of containers accurately and timely, other basic technologies are needed, including database technology, electronic data interchange (EDI) technology and network technology

4 outlook

at present, China's RFID technology is still in its infancy, and has a certain foundation in the application of low-frequency and intermediate frequency products, but there is basically no large-scale mature application case in the high-frequency field; Moreover, the use of electronic labels is closely related to the level of computer information management system and logistics management. In the 1980s, traditional logistics has changed to traditional logistics. Modern logistics includes information industry, distribution industry and warehousing
