Core Tip: RFID, as one of the core technologies of the Internet of Things, enters the logistics field and gradually replaces commodity barcodes, bringing new technology applications to the existing logistics field. Among them, RFID technology-based logistics turnover box development combined with information network platform Construction, the logistics unit will be tracked from single product to packaging combination and pallet, and the whole chain tracking and traceability management will be realized.

As one of the focus technologies of the Internet of Things, RFID enters the logistics category and slowly replaces commodity barcodes, bringing new skills to the existing logistics category. The RFID-based logistics turnover box grows and integrates with the information collection platform. Supporting, the logistics unit will be tracked from single product to packaging combination and pallet, and the supply chain will be tracked and traced. Suppliers at all levels (especially for packaging companies) that make operations and their property chains have changed in logistics.

The turnover of the turnover container logistics company has a high demand for the distribution of raw materials. Taking the electronic product manufacturing operation as an example, the original information required by the company is a semi-product, which is in the process of its procurement. It is often requested that the supplier deliver the product through a specific packaging container (crate) in accordance with a certain specification ratio.

In the procurement of such large-scale production enterprises, in addition to the suppliers of the original materials, there are also suppliers of specific containers, called packaging materials suppliers, who will manufacture reusable totes according to the needs of enterprises.

From the point of view of the high and low travel customers and suppliers involved in the turnover chain business chain, the data supplier including the production company (hereinafter referred to as A) and manufacturing operations (hereinafter referred to as B1, B2, B3...) and packaging materials (Turnover box) suppliers (hereinafter referred to as C1, C2, C3...) and third party logistics.

The operation process is as follows:

● Class A enterprises shall determine the original data orders according to the production requirements, and request the design requirements of the turnover boxes according to the specifications of the original materials;

● The B-type enterprise will place an order to purchase the turnover box. After receiving the confirmation, the packaging material enterprise will produce the product according to the customer's demand and transport the turnover box to the designated network of the B-type enterprise;

● Class B enterprises transport the totes carrying the original materials to the designated network of the Class A enterprises;

●A class enterprise receives the parts after receiving the tote, and returns the tote to the class B customer. After the week B receives the specified amount of life, it completes a turnover cycle of the tote. Peaceful journey.

The process of smooth turnover of the turnover box, this model of logistics process involves production companies, suppliers, packaging materials companies and third-party logistics companies, too many confession links, so that there is a lot of troubles in the process of turnover container logistics Topics (especially for packaging companies):

● High loss of single product: The loss and damage of the turnover box are evenly distributed at 8%/month. The operation of multiple turnovers in the process of circulation increases the possibility of loss, in the absence of information tracking and retrospective management. As a result, when the loss of obligations is divided, it is impossible to obtain a clear definition, which is borne by the weak individual in cooperation.

● Long and smooth cycle: Long-term single-turn process and low application rate. Because of multi-party cooperation and hard work, many turnover boxes are idle after application, while other demanders have to order again from scratch, resulting in capital. Splurge.

● Manipulation process chaos: divergence of control processes between different enterprises, and the manipulation of capital, especially in the inventory management of the totes.

Utilization of RFID Technology in Turnover Logistics

When presenting the above topics, how to use the Internet of Things skills to solve useful problems? The use of RFID technology is a future.

RFID has the characteristics of remote interval recognition, rapid recognition and reflection, information storage capacity and compliance, which makes it a powerful thing to replace the QR code for warehousing and transportation logistics management.

Under the support of the Internet-based information system, RFID can make the daily management of logistics become dynamic, timely, and transparent.

In order to meet the actual needs of the rapid growth of all business chains, all parties in the tote logistics chain hope to realize the same governance of turnover, turnover, rapid turnover, and active inspection and entry in order to calculate the turnover rate through the process of informationization. Next, one of the focus technologies of the Internet of Things is the use of RFID in tote logistics.

RFID skills combined with totes

RFID turnover box overall design RFID turnover box consists of two sub-systems of electronic tags and browsers. The electronic tag is installed on the tote, and the utility model is used for storing the tote identification information, the tote loading information, the waybill information, etc., and the browser is used for reading and writing the electronic tag on the tote.

The information disposition process of the RFID container includes the process of disposing the information on the site of the control site, and it is also the process of the tote into the process, and also includes the in-process information disposal process, which is also the process of the tote transport.

Anti-theft: transport vehicle body electronic seal, integrated door sensor and light sensor, complete the intrusion monitoring of the tote loading body, meet the anti-terrorism and anti-theft requests, etc.; meet the safety request; supervise the condition of the vehicle transportation; Record and store.

Therefore, the RFID container must have the following three-year-night basis: it is possible to closely monitor and actively state the movement of anyone who intends to misappropriate the tote at the on-site, and accurately show that this movement does not have any prestige. Partial prior consent; may, on the premise of decree and on-site agreement, be willing to pay the relevant information to ensure that the parties supply the dynamic and specific status within the supply chain; they can directly send out the contents of the totes from the totes, Relevant data such as status and packing list.

Turnover process

● Packaging materials enterprises: The B-type enterprises purchase orders for the turnover boxes. After the packaging materials enterprises receive the confirmation, they will install RFID electronic tags on the turnover box and start the RFID electronic tags with the handheld terminal/fixed terminal according to the customer's needs. Write relevant information, and then transport the totes to the designated venues of the B-type enterprises;

● Class B enterprise: After the tote box reaches the B-type enterprise end, the RFID reader is used to timely record the time and number of the totes, and the safety status of the totes, and send the information to the management. Turnover box information After the B-type customer is confirmed by the RFID management system, the turnover box monitoring homework is started by the RFID monitoring reader. After the turnover box completes the loading part of the homework class, the B-type customer is really an RFID reader to record the time of the turnover box loading work, and confirm the safety status of the turnover box and the internal contents of the box to ensure that the loading container is safe. After that, the transport vehicle will sail to the designated site of A.

● Manufacturing operation: After the tote transport vehicle enters the designated venue of the production enterprise, after the production enterprise has a real RFID reading assembly, the on-site security staff has already obtained the number of the totes and the internal contents of the box. , check the correct receipt of goods and the status of the turnover box;

● The turnover box is returned from the operation A to the B-type client: after receiving the tote, the A-type enterprise collects the parts in the package, and the to-go box is returned to the same type of management and returned to the B-type customer for real operation. The tripartite logistics company completed, after the week B of the B-type customer received the specified life, completed the safe journey of a turnover cycle of the tote.

Building a shared information platform

In the process of operation, a single turnover box is characterized by multi-party interpretation, multi-point storage, and repeated application. Therefore, simply combining the turnover box with the electronic label is the goal of reducing the loss, the same process, accelerating the turnover and improving the overall effectiveness. It is necessary to collect and build an information platform (warehouse management system, etc.) through the transmission and utilization of the Internet of Things to better manage the revolving flow of the tote.

● The purpose of the information platform is to use the totes as the basic unit of logistics, and to purchase the totes from the B-type enterprises to the C-type enterprises, and then put the parts into the turnover box and send them to the designated warehouse (the warehouse), wait for A to turn over. After the box is returned, the data is collected through the RFID tag reading, and the computer is used to manage the information, so as to avoid the loss of the turnover box, improve the turnover efficiency, reduce the labor link, save time, and count the data. Analyze disposition, supply all kinds of data needed for governance, and provide reliable data for the planners.

● The information platform is based on RFID design: the combination of the tote box and the RFID tag is used to number each box, the box number and the label relationship, and the totes are coherently written into the database (ground library). In the process of turnover of the turnover box, the label recognized by the reader/writer obtains the box number, and realizes the standardization management of the turnover box, thereby promoting the accuracy of the production data. In response to the above requirements, the reincarnation application of the toll box will cause data to be messy, and the information verification of each link will be added in the system to ensure the uniqueness of the information of the turnover box in each link. The information platform conducts the validity check on the to-go box of the next link, and links the information of one link in the relationship to ensure the traceability of the information, and eliminates the situation that the tote box moves across the nodes in the cycle.

Market promotion hinders analysis

The RFID-based tote logistics system has not yet been widely used. However, some enterprises have adopted the department's RFID-based totes into the actual operation, and have made significant progress in loss control, turnover efficiency, and process management. If you want to promote in the industry, there are some topics that deserve further consideration.

The first is the tote reform, the new equipment will be installed, which will lead to the increase in the cost of the turnover box. Compared with the long-term benefits, all the high and low-tour enterprises involved in the smooth process are willing to bear, and the added cost is also Dispatch?

Secondly, RFID's own problem, the metal barrier effect easily occurs in the process of turnaround, resulting in the inability to identify the color information, which requires adjustment of the existing manipulation to avoid the problem.

Finally, the techniques are collected and built. The reincarnation process of the turnover box involves multiple cooperative enterprises. In order to manage every step of the operation, all enterprises must be included in the public information platform, so who will build the platform? If other collaborators apply the topic of the platform, it depends on the actual situation.

The RFID-based tote box is just a miniature of the RFID logistics box in the single product segment. The cost of the electronic label is not as high as it was when it first happened, making it more likely to be used in the material industry. At the international level, Wal-Mart has always been committed to promoting the use of RFID in the world (just as its bar code technique has led to a change in the use of information technology), with the goal of producing from a single product to pallet transport via a single logistics unit. Tracking, and thus achieving full traceability and traceability of the supply chain.

RFID technology enters the logistics category, slowly replaces the commodity barcode, and the combination with the logistics box will positively influence the promotion of digital logistics, truly realize the timely and transparent management of the information of the goods, improve the effectiveness of the logistics industry, and then reduce the logistics cost. .
