ELECTRONIC SEAL FOR FREIGHT CONTAINERS

It is a device that maintains the features of the most advanced commercial systems and completely lacks the mechanical parts of current electronic seals. The invention of the seal includes a microprocessor that is responsible for the integral management of the equipment, an Internet connection system through mobile phone networks, a communications module for short-range communication with users' smartphones and a positioning module that allows the real-time position of containers of goods in transit to be known. The fastening mode is magnetic and incorporates sensors for metal and proximity detection. The magnetic fastening system is completely secure and resistant to shocks and vibrations during transport. The sensors provide a preventive indication of whether an attempt has been made or whether the seal has been tampered with. The elimination of mechanical elements makes possible a compact and sealed design, reduced in size and weight, and very cost-effective in manufacturing. The system is completed with a fleet management application in the cloud, an app for local control of the seal, and a wireless charging module capable of managing an extensive set of seals and preparing them for multiple cycles of use.
