Radio-frequency sealing protection device

The invention discloses a radio-frequency sealing protection device. The radio-frequency sealing protection device comprises a single chip computer, as well as a radio-frequency IC closed ring, an electromagnetic closed mechanism, an RFID reading device and an electromagnetic unlocking control mechanism, wherein enciphering information is stored in the radio-frequency IC closed ring, the electromagnetic closed mechanism is used for locking and unlocking the radio-frequency IC closed ring, the RFID reading device is used for reading the enciphering information of the radio-frequency IC closed ring, the electromagnetic unlocking control mechanism is used for controlling the electromagnetic closed mechanism, a hollow inner ring is arranged in the radio-frequency IC closed ring, the RFID reading device and the electromagnetic unlocking control mechanism are connected with the single chip computer, the RFID reading device is used for reading the enciphering information of the radio-frequency IC closed ring in real time, and the single chip computer cuts off the power supply of a gauge when the enciphering information of the radio-frequency IC closed ring cannot be read out. The radio-frequency sealing protection device has the advantages of sealing, theft prevention and capability of giving an alarm.
