A detection device for cooling apparatuses of a container data center (CDC) includes a processor, a card reader, and a radio frequency identification (RFID) label. The RFID label includes a detection unit received inside the CDC, and wirelessly communicates with the card reader through the detection unit. The detecting unit detects statuses of the cooling apparatuses and environmental parameters of the CDC, and in response to the status of at least one of the cooling apparatuses and at least one of the environmental parameters of the CDC changing, the detection unit electrically isolates the RFID chip from the antenna.
