The National Museum of Fine Arts of Taiwan (National Museum of Fine Arts) recently launched a hybrid radio frequency identification system to manage artworks in warehouses, the movement of tourists and determine the location of artworks in exhibition halls in real time.The solution is provided by EPC Solutions, which includes active and passiveRFIDCarts, warehouse stationary passive RFID outlets, passive tags attached to artwork and software to manage data. Liu TH, president of EPC Solutions Taiwan, said that the system also includes a reader that reads warehouse information and cart information.
The main building of the National Art Museum of Taiwan covers an area of 37,953 square meters and the outdoor sculpture park covers an area of 102,000 square meters. It is the largest art museum in Asia. The museum has 20,000 works of art from all over the world. The main building of the museum is a three-story building with a basement area of about 14,600 square meters.
In order to ensure the safety of the artworks exhibited or stored in the museum, the museum has deployed a system based on RFID technology since 2006, and 433MHz RFID tags will be attached to the staff and artworks. The reader captures the ID number on the tag, so the museum’s software can tell if the artwork is moving and keep it safe based on the employee’s path.
However, due to size and cost, it is impossible to put labels on all artworks. In addition, active tags themselves can cause false alarms. To make matters worse, this solution cannot yet support data on the movement of artworks between warehouses and exhibition halls.
So, to solve this problem, EPC attaches one Gen2 UHF passive tag for every 20,000 artworks. These tags are ALN-9654 tags provided by Alien Technologies. In addition, EPC mounts the FlexAnt reader to the wall using coaxial cable. In this way, data on the status of the artwork can be provided in real time.
The company mounts a Microprogram-supplied MP-1303 active 900MHz tag on each hauler, which transmits the hauler’s real-time location within the building. Each truck is also equipped with a passive RFID reader, FlexAnt antenna for reading artwork tags. To track the active tags on each vehicle, the museum has also installed 15 Alien ALR-9900+ EPC Gen 2 RFID readers, so that the museum knows whether a delivery vehicle is in the warehouse or between warehouses and exhibition halls. state.
EPC also installed 16 stationary ALR-9900+ at the warehouse exitReader, Futaba software is deployed in the back-end system of the museum for data management. In addition, the museum has installed a camera at each exit. If the software detects that the item is being moved, the camera provides a video of the artwork passing through the exit. At this time, employees can also use the ATID AT-870 handheld reader to search for specific objects for spot checks.
In addition, EPC has developed a dual-band 900 MHz, 125 KHz active RFID system to track the location of visitors and workers within the warehouse. Every visitor gets a badge with a built-in RFID tag. In this way, the museum is informed of the visitor’s location throughout the warehouse and exhibition area.
All 433MHz active readers will be replaced. So far, EPC has installed an ALR-9900+ 902-928 MHz reader in one of the museum’s exhibit halls. The system also uses FlexAnt cable antennas to provide high-precision positioning data without the need for active tags.
“It looks like a normal coaxial cable,” Liu said. The cable is flexible and can be extended in length according to actual conditions. Essentially, it is a UHF antenna and emits electromagnetic waves 20 to 30 meters long. Liu added that EPC’s FlexAnt has been in commercial use for about a year.
The cables are usually installed behind the display wall and are therefore not visible. “It can be installed in any environment, including metal,” Liu points out. EPC is currently promoting the technology.
In the near future, the museum will install Alien readers in another 23 exhibition halls, Liu said. Starting next month, the Gome Museum Art Bank intends to lease modern artworks to corporations and other private institutions. So museums will put labels on these artworks. In this way, it is possible to record the rental, the time of return, and the object.
