1 Basic situation of the company
Shenzhen Baisha Logistics was established by Baisha Group in 1992, with a total investment of 250 million yuan and a registered capital of 60 million yuan. A few years later, Baisha Logistics has become a well-known third-party logistics company far and near. At present, Baisha Logistics has a modern warehouse building of 40,000 square meters, a modern single-story steel structure warehouse of 7,000 square meters, and a comprehensive platform building of 15,000 square meters.
2 Questions raised
Some customers of Baisha Logistics have a fast update speed, and often require certain products to be shipped out of the warehouse according to the designated barcode. According to the previous logistics management model, Baisha Logistics could not confirm the precise location of each item. Although the products have barcodes, they are in the thousands of square meters. Look for a few barcodes in the warehouse. Is it easy to talk about? Baisha Logistics often has to send more than a dozen people to look for, and even the manufacturer has sent several people to search one by one, resulting in serious waste of manpower and material resources. In addition, in order to facilitate the search for goods, it is necessary to leave more passages when stacking goods, so that the warehouse utilization rate is only 30%. Both the customer and Baisha Logistics are dissatisfied with this. In this case, how to improve efficiency and warehouse utilization has become a problem for Baisha Logistics.
3 Application of RFID technology
The emergence of RFID has solved the problem of Baisha Logistics.
In Baisha LogisticsRFIDIn the system, the biggest “secret” lies in the electronic label on the tray. This electronic tag with a length of about 8 cm and a width of about 2 cm is like a small memory, which can store about 1,000 bytes. The user installs this electronic tag on the pallet. Before the goods are put into the warehouse, they only need to read the barcode information of the items on the pallet with a handheld reader, and then enter it into the electronic label, and all the goods information on this pallet will be stored in In the terminal computer, that is, in the fixed reader. With the handheld reader, the information entry work before storage can be completed in the workshop of the production plant thousands of miles away.
In the Baisha Logistics warehouse, when the goods are out of the warehouse, the loan number that needs to be out of the warehouse is first input into the computer, and the computer immediately displays the shipping bitmap, and transmits the form of the result team list to the handheld reader. The operator can find the goods smoothly through the instructions of the handheld computer, pull up the pallet of loaded goods, scan the electronic label on the pallet through the handheld reader, and then press the “out of library” button, the goods on the pallet can be Out of the library.
If the goods on the pallet are different from what is displayed in the computer, the monitoring doors located on both sides of the warehouse gate will sound an alarm. This batch of goods needs to be processed again in accordance with the “out of warehouse” process until there are no errors.
The application of Baisha Logistics’ RFID system is the “pallet + barcode” management that combines RFID and barcode. In other words, “electronic tags” are installed on nearly a hundred pallets, and each item is still “barcode”. The RFID system uses the dynamic information of the electronic tag to manage the static information of the bar code. Each process of the movement of the goods is automatically recorded and processed by the tag and the reader. This has avoided a large part of mechanical repetitive labor, so the current warehouse management efficiency and accuracy have been greatly improved. The warehouse utilization rate of Baisha Logistics has been increased from the original 30% to 80%. At the same time, since the pallets are reused, the electronic tags are also reused accordingly, so that the hardware cost has been effectively controlled.
At present, although Baisha Logistics’ RFID system is still in the trial operation stage, it has shown great development potential. It is a typical combination of RFID technology and bar code, and is the first to apply RFID technology to warehouse management in my country.
In the United States, Ship2Save has officially launched an intelligent warehouse facility using RFID systems. This is the most advanced warehouse with automated equipment in North America. These devices can not only control inventory, but also distinguish various goods and detect the movement of goods. If goods are taken without being recorded, the facility will issue an alarm. Conrad, the company’s senior business analyst, pointed out that the technology used in this smart warehouse facility can ensure the safety of all customer goods. When using traditional passive tags, the goods must be monitored at the specified reading point; while using active tags, whether someone wants to move the goods, or someone wants to break the tag or try to tear off the tag, or someone tries to stop the reader Read the tag, the device will know. And when those who try to do these things realize that they are doing it in vain, the warehouse is automatically locked, and the warehouse manager will be alerted at any time.
4. Obstacles to the development of RFID in warehousing and logistics
Whether from Ship2Save in the United States or Baisha Logistics in my country, we can see the high education and accuracy of RFID storage logistics with cockles. RFID technology replaces the existing bar code technology and will become an inevitable trend in warehousing and logistics. The application of RFID technology in warehousing and logistics is gaining momentum.
For warehousing and logistics, the biggest obstacle currently restricting the RFID carbon exhibition is technical standards. At present, there are two coding systems for the application of RFID in logistics: one is the UID coding system proposed by the Japanese UID Center (the center is actually the Japanese electronic label standardization organization). Japanese electronics manufacturers support this camp. , Information companies and printing companies, etc., have a total of 352; the other camp is the EPC electronic product coding standard proposed by the US EPC (Electronic Product Code) Universal Association. More than 100 circulation companies in the United States and Europe, including the world’s largest retailer Wal-Mart Chain Group and British Tesco, are all members of EPC. At the same time, they are supported by technical research by IBM, Microsoft, and Auto-ID Lab in the United States.
Due to the difference between the two coding systems, the application and development of RFID technology are seriously affected. There are ten unique identification codes in each RFID tag of Tuanwei. If its data formats are many and are incompatible with each other, then RFID products with different standards cannot be used universally. This is a problem for the circulation of goods under economic globalization. Very unfavorable. The issue of data format standards involves the interests and security of each country.
How to make these standards compatible with each other so that an RFID product can circulate smoothly around the world is an important and urgent problem that needs to be solved at present.
Another problem that needs to be resolved is the price of electronic tags, which is also an important aspect that affects the application of RFID. Because warehousing is to store large quantities of items, if each item is affixed with electronic tags and each tag is expensive, the storage cost will also be greatly increased. Only when the price of electronic tags drops can it be possible to order and use RFID in batches. Otherwise, not every manufacturer can afford the cost brought about by the high price of electronic tags. It is reported that Japan has established a low-price strategy for electronic tags. The national project called “Echo Project” hosted by the Ministry of Economy, Trade and Industry of Japan has undertaken to develop a price of 5 yen within two years from August 2, 2004. Technical development of electronic tags. The goals of the “Echo Project” can be summarized as follows: One is to reduce prices, and the other is to comply with national standards and regulations.
Other aspects, such as radio frequency receiving distance limitation, radio frequency radiation to the human body, and the frequency limitation faced by RFID, are also obstacles in the development of RFID.
