RFID Application in container monitoring the rise of intelligence in global ports

recently, the California Institute of public policy released a report on improving port security. They believe that the use of radio frequency electronic tags (RFID) and all-weather remote sensor systems for container monitoring can not only improve the security level of ports, but also bring obvious commercial benefits to enterprises. With the development of Global trade and the improvement of ship capacity, about 5.8 billion tons of goods are transported by sea every year, that is, 80% of the global trade volume, but only about 5% of containers will be tested. How to protect the safety of 11million containers transported by 46000 ocean ships to 4000 ports around the world has become an issue of great concern. After the "9/11" incident, the United States paid more attention to this issue. With the help of modern information and communication technology, new technologies including RFID chips, sensors, authentication technology, tracking technology and detection technology were applied in ports. Improving the level of intelligence is one of the development directions

the "container security initiative" (CSI) has been put forward in the global anti-terrorism strategic deployment of the United States. The initiative aims to establish a mechanism to protect the security of global shipping container trade. In 2002, CSI began to use information technology to identify and inspect high-risk goods in containers. Through global positioning technology (GPS), electronic tag technology (RFID) and sensor technology, the container security system will make the whole transportation process of containers in intelligent and networked monitoring. These measures can not only effectively strengthen the government's supervision of goods and improve the level of national security protection, but also help shippers timely understand the transportation status of goods and prevent the loss of goods. It can be said that the intelligent inspection of ports and containers has achieved the goal of "killing many birds with one arrow", so many governments around the world have begun to actively promote the implementation of this initiative

it can meet the requirements of durability testing, testing of the relationship between tightening range and pressure, and testing of spring tightening under specific pressure. In January 2005, general electric safety group released an electronic system for the container safety market, and completed a commercial test of cross sea transportation in cooperation with Chinese container enterprises. 18 containers equipped with Ge security system were transported from mainland China ports to the United States through Hong Kong. Before shipment, technicians recorded the first loading and sealing information of the container with a handheld RFID reader. Fixed RFID readers are installed in Hong Kong port and Long Beach port in the United States to record the whole process of unloading full containers from the ship. When the container arrived at its destination, General Electric factory in California, technicians used a handheld RFID reader again to read various information recorded in the transmission process. The information shows that 12 of the 18 containers were not opened, but 5 of them were opened during transportation, and the remaining 1 was opened after sealing and before sailing. In this way, the shipper can fully understand the transportation process of the container

with RFID installed, the second generation ABS not only enters the mass-produced containers, but can record their sealing, opening and other information, but cannot provide more detailed information. In contrast, sensors can provide richer functions. The sensors installed in the container can detect factors that need special attention, such as radiation, biology, light, object motion, temperature, explosives and specific chemicals. In the summer of 2004, the Korean government began to plan the "smart container" project, which was officially launched in December 2004. This project, called "RFID maritime logistics", is equipped with smart RFID and sensors on the "smart container". On the way from Busan Port to the west coast of the United States and major ports in Europe, with the help of the monitoring of transportation security system software, background managers can get all kinds of information in real time, so as to strengthen the efficiency and security of international trade between South Korea and other countries

although experimental projects have been carried out, with the popularity of sensors in the field of containers, cost has become the main problem that people must solve. Behind the trend of intellectualization, there are huge expenses - not only new containers, but more than 30 million existing dry cargo containers in the world need to be transformed. The transformation cost of installing RF tags in each container is about $200, which is a huge expense of more than $6billion (more than the total annual output value of the global container manufacturing industry). If a more advanced sensor system is installed, the cost per container will increase by $500

port management should balance the relationship between safety and cost. Therefore, how to eliminate the impact on economic development while promoting intelligence has become a "headache" for governments of all countries. Shortening the customs clearance time and improving the real-time control ability of goods are the current main measures. For example, container importers using RFID will have priority in entering the United States. For those importers who do not do so, it will take more time for the goods to pass the customs, "Paul said. In this way, it also depends on the breakthrough in cost. Shippers who have high requirements for transportation time will tend to use intelligent containers. Experiments in ports such as Los Angeles have confirmed this

this port test system uses real-time location system technology to automatically collect container data entering and leaving the freight yard, so as to improve the speed and accuracy of container handling at the terminal. At the same time, RFID is affixed to all trailers and trailers in the freight yard affiliated to the port of Los Angeles, so that the container data collection process is fully automated. At present, all containers entering and leaving the dock are transported on trailers. The system can instantly identify the containers on the trailers with RF tags and confirm their positions. This measure will effectively reduce the container handling and circulation time (it is estimated that the time saved can reach more than half a day)
