Tamper evident cargo container seal bolt lock

摘要

Systems and methods for a tamper-evident cargo container seal bolt lock are disclosed herein. The device can include a bolt member having a conductive medium running the axial length of the bolt, and a receiving member for locking the bolt into place. A battery-driven sensory circuit including a memory, a processor, and a timing circuit can be disposed within the receiving member such that a continuous circuit is formed from one circuit pin over the conductive medium through the length of the bolt and back to a second pin. The sensory circuit is configured to sense whether the circuit has been interrupted (e.g., if the bolt has been cut). In the event of an interruption, the circuit can record the time and/or date in memory. This information can then be transmitted to an RFID reader/interrogator if a dispute arises as to when the lock had been broken.

主权项

1. A bolt lock device comprising:
a bolt member comprising an electrically conductive medium running between a first end of the bolt member and a second end of the bolt member; and a receiving member adapted to receive the first end of the bolt member, the receiving member comprising a battery-operated sensory circuit with memory and pins adapted to form an electrically conductive pathway through the conductive medium of the bolt member after the first end of the bolt member has been inserted into the receiving member; wherein the sensory circuit is adapted to detect whether the circuit has been interrupted and record in the memory the date and time that the circuit was interrupted.
