Wherein, RFID signs response module 1 does not have the problem of the missed measure label that sliding sleeve switch instrument rotation leads to. When the sliding sleeve opening and closing tool passes through one RFID label point, the RFID card reader of the sliding sleeve opening and closing tool can read the information of the RFID label, the central processing module compares whether the read information of the RFID label is consistent with the information of the RFID label stored in the setting process, if the information is inconsistent, the target sliding sleeve is not opened, and the sliding sleeve opening and closing tool can continue to move; if the information is consistent, the target sliding sleeve at the position needs to be opened, the action execution mechanical structure is triggered at the moment, the target sliding sleeve is locked by the ejection mechanical structure, and the pipeline blockage is formed at the position.
