Magnetic meridian lock

Abstract

The invention discloses a magnetic meridian lock which comprises a modified compass and a control circuit. A thin conductive wire is arranged above a magnetic needle of the modified compass, electricity can be conducted between the thin conductive wire and a shaft for supporting the magnetic needle, and the shaft is connected with the control circuit by a soft wire; a horseshoe-shaped conductor is arranged on an inner side of a compass box cover and is connected with the control circuit by a soft wire; two ends of the horseshoe-shaped conductor are adjusted and are not in contact with the thin conductive wire above two poles of the magnetic needle when the magnetic needle of the modified compass is stably positioned in the direction of a local magnetic meridian, so that the orientation of a constrained object relative to the local magnetic meridian can be locked; once the direction of the locked object changes, the thin conductive wire on the needle is in contact with the horseshoe-shaped conductor, the control circuit can be switched on, a loudspeaker can be started to generate a sound, and a mobile phone of a user can be dialed. The magnetic meridian lock has the advantages that the magnetic meridian lock is simple in structure, easy operate small in size and low in manufacturing cost, and people can be inspired to utilize magnetic meridians.

Description

technical field [0001] The invention mainly relates to the field of signal and information processing, in particular to a magnetic meridian lock. Background technique [0002] When people sail, travel, and build structures, they often use the direction of the magnetic meridian of the earth as a reference, but when they need to detect the movement of objects or prevent theft, they do not use the magnetic meridian given to us by nature. [0003] For anti-theft, people put locks on their cars, boats or objects, and set up various obstacles to prevent objects from moving for the thief. The "lock" so far is to lock the anti-theft object with a nearby larger object, and it is believed that the larger the locked object, the safer it is. This kind of lock is fully exposed, and the object it locks is visible and tangible. If the thief destroys the lock or destroys the locked fixed object and robs the object, the owner in the distance will have no way of knowing whether his thing...

This kind of lock is fully exposed, and the object it locks is visible and tangible. If the thief destroys the lock or destroys the locked fixed object and robs the object, the owner in the distance will have no way of knowing whether his things are still in place, let alone protect the thief. track and intercept
