The Application Of RFID In Cool Chain Wang Naiqian 5100309318 Li Yining 5100309296 He Yi 5100309186 Zheng Zhoulong 5080309369 Hong Xingzhu 5070309249 Yang Ziwen 5100729002 Abstract—This research discusses the application of RFID in cool chain.The RFID based system consists of a smart tag and a commercial reader/writer. A commercial reader/writer was used for reading and writing data on the smart tag, with a wireless reading distance of 10 cm, in real-time at any time of the food chain. The results concerning a demonstration of the system along an intercontinental fresh or frozen food logistic chain are reported here. The efficient and effective tracking of cool chain conditions is one of the main points to be addressed. In the future, RFID will greatly improve the efficiency of logistics if it widely used for the control and management system of logistics. I. INTRODUCTION Cool-chain logistics management refers to a systematic logistics project which the temperature-sensitive products are always provided in low-temperature environment in every aspect such as production, storage, transportation, marketing and consumption, to ensure quality goods, reduce wear and tear of logistics. It is also a low-temperature logistics process which based on refrigeration technology. Cool is a supply chain system which ensures that the core requirements of maintaining low-temperature environment for the purpose of maintaining perishable goods quality, so it has higher requirements than the general logistics system at room temperature. Avoiding significant personal accident due to food, medicines which lack of effective cool chain logistics management, are the responsibility of the government and enterprises. The original means of monitoring techniques are the biggest technical bottlenecks in our country now.The main crux of the technical is: artificial measurement and paper records, no unified data system support, bad real-time, regulatory out of touch, evidence difficulties, failure to determine responsibility, no warning and the loss rate is high. In this regard, the industry hopes the application of advanced RFID technology in the temperature required management such as logistics management and production flow management. The smart tag, attached on the product to be tracked integrates light, temperature and humidity sensors, a microcontroller, a memory chip, low power electronics and an antenna for RFID communications. These sensor logged data can be stored in the memory together with traceability data.Temperature changes will be recorded in the RFID tags with temperature sensors for the quality and meticulous, real-time management of the fresh products.Due to the progress of the technology standardization and IP network driven by demand for efficient information transmission, RFID is closer to practical system. In addition the rapid development of IP network and information management technology has provided a broad space for RFID information and RFID application. This research mainly discussed about the cool chain logistics,the RFID technique, and the cases where RFID is applied, and the RFID-application in the cool chain logistics as well. At last,the problems and future will be considered. II. COOL CHAIN Cool chain is a logistic system that provides a series of facilities for maintaining ideal storage conditions for perishables from the point of origin to the point of consumption in the food supply chain. The chain needs to start at the farm level (e.g. harvest methods, Pre-cooling) and cover up to the consumer level or at least to the retail level. A well organized cool chain reduces spoilage, retains the quality of the harvested products and guarantees a cost efficient delivery to the consumer given adequate attention for customer service. A. Constitution The main feature of the chain is that if any of the links is missing or is weak, the whole system fails.The Cool chain logistics infrastructure generally consists of: Pre-cooling facilities, Cold Storages, Refrigerated, Carriers, Packaging, Warehousing, Information Management systems (Traceability and Tracking) etc. B. Objective The temperature controlled supply chains or cool chains are a significant proportion of the retail food market. The market shares of fast foods, ready meals and frozen products have increased in recent years. There are several food temperature levels to suit different types of products. Frozen, cold chilled, medium chilled, and exotic chilled are some of the frequently used nomenclatures with specified temperature ranges, depending on the products, whether it is meat or ice cream or potatoes or bananas. With the growing demands to keep and distribute temperature sensitive products in potent condition, organizations are seeking better solutions to maintain and monitor cool chain. The success of implementing cool chain management involves continual monitoring of product temperature throughout distribution and having appropriate corrective action plans in place. A streamlined, well maintained cool chain helps to: Reduce costs, Improve product integrity, Increase customer satisfaction, Reduce wastage and returns of expired stock. III.

impacts on many industries. Radio Frequency IDentification, or RFID, is a low-cost, practical way to identify and keep track of almost anything – from wildlife to goods in a warehouse. The technology centers on electronic ”tags” which store data and respond to a radio frequency reader device. A. RFID Tag An RFID tag is an electronic device about the size of a grain of rice. The tag contains an antenna and a microchip with data storage.When the antenna receives a specialized radio signal, the microchip ”wakes up” and uses the antenna to send a message of its own. A tag can store up to 2 KB of data, far more than bar codes, which are also used to track items. Because the system uses radio waves, an RFID tag still works when embedded inside an object or packaged in a container. With the right radio signal, you can reprogram an RFID tag with new information, making it reusable and useful for a variety of tasks. B. RFID Reader An RFID reader combines the functions of radio transmitter, receiver and data interface. The transmitter activates the tag, the receiver reads the tag’s response and the interface passes information along to a computer or other equipment. The size and configurations of readers varies; some are handheld units, others are stationary, such as the theft detection devices at a retail store’s exit. A stationary reader typically transmits its signal continually, waiting for a tag to pass within a few meters, at which point the tag sends its data. C. Data Retrieval A computer picks up the data sent to it by the RFID reader. The computer may display the tag’s data directly, or it may look the data up in a larger, seperate database. For example, a factory uses RFID tags to keep track of car doors. When a truck delivers doors to the loading dock, a reader scans the tags and passes the information to a computer. The computer finds the tag’s record in a database and marks the record as ”received.” When workers paint the doors, another reader scans the doors and marks their records as ”painted.” In this manner, the factory management can determine exactly how many doors it has, and how many are finished. D. Uses Many companies use RFID tags to track the flow of goods through warehousing, distribution and retail. In the case of recycling, they can even track goods returned. The tiny size of the tags makes them ideal for tracking pets. A veterinarian can implant the tag just under the animal’s skin and programs the tag with the owner’s name and address. Security companies place tags in access cards. A reader detects the card’s presence in your pocket and automatically unlocks doors and turns on lights. Many types of RFID exist, but at the highest level, we can divide RFID devices into two classes: active and passive. Active tags require a power sourcełtheyre either connected to a powered infrastructure or use energy stored in an integrated battery. Passive RFID is of interest because the tags dont require batteries or maintenance. A passive tag consists of three parts: an antenna, a semi- conductor chip attached to the antenna, and some form of encapsulation. 1) Near-field RFID: However, near-field communication has some physical limitations. The range for which we can use magnetic induction approximates to c/2f, where c is a constant (the speed of light) and f is the frequency. 2) Far-field RFID: RFID systems consist of three components in two combinations: a transceiver (transmitter/receiver) and antenna are usually combined as an RFID reader. A basic RFID system consists of three components: An antenna or coil A transceiver (with decoder) A transponder (RF tag) electronically programmed with unique information There are two types of transponders, which correlate to the two major types of RFID tags. Passive transponders and RFID tags have no energy source of their own, relying on the energy given off by the reader for the power to respond. Cheaper, passive RFID tags are the most likely to be used for consumer goods. An active transponder or tag has an internal power source, which it uses to generate a signal in response to a reader. IV. APPLICATION A. Turkey Frozen Meat Retailers The largest frozen product retailer in Turkey, BereketDoner, now is using RFID system provided by RFID Enabled Solu-

This RFID system not only can enhance the visibility during the process of operation, such as the time of plating or weighting, but also can help guard against theft. There placed the RFID reader-writer at the exit, which will lead the system sound the alarm when the theft phenomenon happens. This system includes the reader-writer placed at the scale as well as the exit, and the AIMS data software which is used to store the tag data at the background.

Using Motorola XR400reader-writer to read RFID tag, and send the information about weight, temperature, RFID code number, date of manufacture to AIMS inventory order control system. AIMS software can share the data from SQL data base, and can receive the order information at any time. If the products information is different from the order, the system will make an alarm and show it on the screen. It can also monitor the temperature of the products so that the workers can make some change for goods protection. The system enhances the efficiency of transportation. Test shows that RFID tag can work under minus 40 degree. B. Food Drugs Recently TempTrip Company announced a new onetouch temperature tag, which can simplify the food and medicine supply chain manage process, and this tag using RFID technology would be smarter than before. The new tag using MonzaX-2K chip is at the same size as a credit card with a button on it. After pressing the button, the tag begins to work, and record the temperature through the supply chain. If the temperature out of range, the LED light on the tag would turn red, otherwise the light is green. This tag can be put on the cover, box and the plate, and can store thousands of data. It can work in an environment of -30 +55 degree centigrade, with the accuracy +0.2. When being transported or stored, people can reset the tag and let it record the time and the position information, as well as the temperature. Data can be transferred to TempTrip data base and get the feedback within 24 hours. V. CASE The demand for RFID technology is increasing at a fast pace, especially in the healthcare industry, but not only limited to that. Now, Panalpina has integrated active RFID sensors in a third of its air cargo, since it is temperature sensitive. The company is now using SmartView technology on its cool chain network, and SmartView is also being integrated into the companys IT platforms for seamless launching. The shipments being moved by Panalpina are healthcare shipments for the most part but Panalpina is also responsible for moving pharmaceuticals, chemical pre-products, dangerous and hazardous substances, printing machines and high tech wafers. SmartView is an active RFID-based temperature control system from Ambient Systems, an award-winning solution for cool chain optimization. Panalpina uses SmartView in its own controlled freight network. With RFID, temperatures can be recorded over-the-air and continuously monitored in the transit warehouse and while on the road when being transferred from the warehouse to the planes take off location. Every 15 minutes, SmartView system will record the temperatures using the RFID sensors, which are attached onto the shipment. Once the plan reached the delivery location, the information is automatically transferred to the central database. The Panalpina routers are typically located in the airport transit warehouses. Panalpina is also currently working on a system, which will make temperature monitoring of individual shipments directly accessible to its customers. VI. PROBLEMS AND FUTURE At present, there has formed a complete system of agricultural products cool chain logistics in some foreign countries such as the United States, Canada, Germany, Italy, Australia, Japan, South Korea and so on. Whats more, in some countries, the cool chain circulation of fresh perishable agricultural products has accounted for 50Cool chain system in our country, however, there are many deficiencies. Firstly, the food cool chain system in our country has not yet formed complete frame. Secondly, with the uneven market culture degree operators engaged in the food cool chain will hinder the development of cool chain area. Thirdly, the lack of corresponding hardware facilities construction and the lack of integration in food cool chain system also plague us. In a word, we need a new technology to save our cool chain system, and this is the RFID. Therefore, RFID has huge potential for cool chain area in China, and will have a bright future. A. Advantages We can draw from the explanations of the students before that the advantage of RFID technology is to integrate the information technology and logistics industry. It not only improves the efficiency of cool chain logistics, more importantly, it has changed the supply chain process, thus makes originally separation system effectively integrate in the supply chain

Problems Many supporters of RFID is very confident, even think that ”the future every grain of sand will have their own RFID tag”. But just like any other new technology, RFID technology although conspicuous and market prospects look good, but today, its development is not as rapid as the media expected. RFID technology is fraught with difficulty in the application process, so is in the cool chain industry. 1) The Cost: Bar code is mainly takes paper as the carrier or the ink printing on surface of commodity packaging, the cost is very low, as long as a few cents. Compared with bar codes, RFID tags are physical chip combined with wireless sensing technology to realize information recognition and acquisition, so the price of RFID tags is higher. For example, in the United States, the cost of one RFID tag is 20-50 cents. It is almost ten times the price of bar codes. In cool chain industry, we use RFID tags to replace the barcode completely, so the demand is very large. After using RFID technology, logistics costs will increase greatly in cool chain. Whats more, to build such a complete supply chain based on RFID technology, we must rely on ”solid” back-end systems. Enterprise must invest to establish an RFID system and a combination of the original system to make a perfect one, so as to achieve the real application of RFID technology in cool chain. Therefore, it will be a lot of costs, and no matter to suppliers, producers or sellers are unwilling to accept. 2) Privacy And Security Issues: i. Personal tracking Customers bought frozen food in the supermarket, and after payment, due to its electronic label is not cleaned up, it will still send information to radio waves by some readers matching with frequency and phase. In this way, customers who buy these frozen food will no doubt by tracking, thus invaded their privacy. ii. Information security The RFID system is likely to become the new target of hackers, and loss of confidential data. 3) Standardization: No matter what kind of industry and what kind of technology, perfect standard system is of vital importance. Wal-Mart, for example, have keen to test the RFID technology. But because of the RFID existing recognition rate, Wal-Mart decided to go slow process of electronic label application. What is related to the standardization? In the cool chain, I think is the temperature, the most important variation in the system. For example, we put the RFID tag on the bottom of products and it will have a result of temperature. However, if we put the tag on the top of same products, it will show another result. C. Methods 1) Five Cents Label: Many enterprises in the cold supply chain is on a low information level and they care about most is often the cost. So, to solve the problem of RFID popularization, the primary task is how to reduce the cost of RFID tags, realize ”five cents label” goal. i. Break the technical problem to reduce components cost in RFID label. ii. Increase the cost of production, thus the cost decline. iii.Relying on the government macroeconomic regulation and control, give more opportunities and space to show abilities of emerging technologies. 2) Solve The Problem Of Safety: The fundamental solution is to improve reliability from the RFID technology, such as killing tag, electronic shielding and so on. 3) Formulate Local Standards: In different places, the development of cool chain industry and preservation conditions for frozen products is different. Therefore, the differences of region determine the necessity of local standard. Have unify, ”localization” of the RFID standards in the supply chain can let enterprises barrier-free in cooperation and information communication. It also can give full play to the function of RFID technology in cool chain logistics. VII. CONCLUSION This research provides a more comprehensive functional solution for cool-chain logistics industry. To ensurecoolchain products in the production, circulation, storage,sales and other aspects of the temperature requirements can reduce the flow loss of metamorphic goods and storage, facilitate retrospective information and help to identify the responsibility of the accident, realize real-time temperature monitoring and recording, improve cool-chain food safety and enhance consumer confidence, thus increasing the economic efficiency of enterprises.RFID technology in China is bound to arise to a process of change in the field of cold-chain logistics management.As a global manufacturing base and one of the main markets of RFID, domestic enterprises of cool chain industry in China will be the biggest RFID users. By RFID technology development and favorable factors such as our upcoming of RFID standards, RFID applications in cool chain will show a trend of rapid development in our country.
