RFID air cargo management

RFID (Radio Frequency ID, radio frequency identification) technology was born during World War II. In the past two decades, as the application technology environment has matured, RFID has sprung up, attracting the attention of many companies.

Compared with traditional barcodes, RFID has the following advantages: no light source is needed, and data can even be read through external materials; long service life, able to work in harsh environments; data can be written and accessed; the content of the label can be dynamic Change; can handle multiple tags at the same time; the data access of the tags is protected by a password, and the security is higher; the objects attached to the RFID tags can be tracked and located.

These unique features of RFID have won the favor including air transportation. In recent years, with the rapid development of air cargo business worldwide and the widespread application of automatic sorting technology, higher requirements have been put forward in air cargo logistics for improving the efficiency of freight and reducing the error rate of sorting. The application of RFID technology in air cargo management can provide users with improved efficiency and reduced error rates from cargo agent receipt to airport cargo station, security inspection, boarding, and ground service handover, and can monitor the implementation position of cargo . This provides reliable technical means for the air cargo industry to further increase transportation capacity, rationally utilize transportation resources, and improve service quality. Increase the visibility of goods; reduce operating costs; improve customer service levels and customer satisfaction.

The application of RFID solutions to airport cargo management needs to solve the problem of data collection/analysis and establish a basic data source for air cargo transportation management.

Establish a high-efficiency, low-cost and accurate air cargo tracking system to meet the requirements of the transportation safety management department for real-time monitoring of all international air cargo. By using active RFID electronic tags and reading and writing equipment, the airport can establish a new process for automatically tracking all air cargo to ensure the safe flow of millions of international cargo at the airport.

From the airport, the cargo company to the airport deploys 2.4GHz readers provided by Bayside Technology to collect trucks and cargo in real time, so as to optimize the airport’s arrangements and scheduling for air cargo loading and unloading.

When the airport receives the cargo information from the air cargo company, it will arrange the unloading space of the cargo yard in advance according to the cargo name, category, flight, route, truck number and other information.

The freight company sets up points to install readers along the way to the airport. The airport control center monitors the trucks on the way in real time and knows the location of the trucks in time; the airport can adjust the parking space according to the difference between the arrival time of the trucks reported by the freight company and the actual possible arrival time. In addition, an anti-theft electronic lead seal is installed on the carriage to ensure the safety of the goods in transit.

When the truck arrives at the airport, it enters the parking lot and waits for the unloading space. The airport control center reasonably dispatches the unloading trucks according to the queue status of unloading trucks, cargo information and flights, so as to ensure the unloading of air cargo and clothing.

The goods are loaded into the warehouse, and the readers installed in the warehouse can read the information of the goods with active tags in real time, and check whether the goods for the scheduled flight are ready in time, and check whether the goods are in the correct position in the warehouse.

When the plane arrives at the airport and waits for the cargo to enter the warehouse, the reader installed at the cargo entrance of the aircraft reads the cargo warehousing information. The reader immediately turns off the electronic tag after receiving the cargo warehousing information, and the active electronic tag enters sleep since then Mode, until the RFID device is reactivated when the cargo gets off the plane, it will start to work again.
