Abstract

The invention relates to a low-power-consumption optical fiber electronic seal comprising an optical fiber connector, an optical fiber, an optical transceiver module, a timing unit, a main controller, a serial port communication module and a data storage device. An optical signal transmitted by the optical fiber is converted into an electric signal through the optical transceiver module to be input into the main controller, the optical fiber connector is connected with the optical transceiver module, and when the optical fiber is turned on or off, a pin of the optical transceiver module transmits the electric signal to the main controller, the main controller immediately reads the electrical signal into instantaneous time in the timing unit, and a data, time and the state of optical fiber are stored into the data storage device. The low-power-consumption electronic seal operates with low power consumption, improves efficiency of on-site inspection, reduces the risk of sealing nuclear material and is high in tamper-proof capacity.

Description

technical field [0001] The invention relates to the technical field of nuclear material control, in particular to a novel low-power optical fiber electronic seal. Background technique [0002] Nuclear material accounting and control is the main means of international nuclear safeguards and domestic nuclear material control. Nuclear material control plays an important role in timely detection of theft, illegal use, and illegal transfer of nuclear materials, and timely detection of unauthorized access to nuclear materials by verifying the integrity of physical objects or containers. Unauthorized access to nuclear material may be for the purpose of stealing or destroying nuclear material in containers, rooms, buildings, trucks, railcars, packages or equipment. Elements of nuclear material control include: containment, surveillance, access control, detection / review. Sealing technology is an important technical means of nuclear material control. It is a tamper indicating devic...
