OPTICAL-MECHANICAL UNIT FOR CONTROL OF CONNECTION AND FIXATION OF PARTS OF CONTROL OBJECT USING FIBER-OPTICAL CABLE ELEMENTS WITHOUT OPTICAL CONTACT BETWEEN THEM Russian patent published in 2021 - IPC G08B13/186 

FIELD: security systems.

SUBSTANCE: invention relates to optical-mechanical assemblies and can be used in security systems, in particular, to control the state of "open-closed" gates, gates of alarm barriers, control the opening of hatches, control the integrity of networks woven from an optical cable, the safety of individual items of movable property such as a motorcycle, car, boat, airplane, etc. The specified technical result is achieved through the use of an optomechanical unit for monitoring the connection and fixing parts of the test object using fiber-optic cable elements without optical contact between them, consisting of a magnetoactive module containing an optical collimating device with a movable shutter made of magnetic material and made with the ability to connect with an optical cable connected to one part of the controlled object; and a permanent magnet capable of being attached to another part of the test object, and in the operating state of the assembly, the shutter is movable under the action of a permanent magnet.

EFFECT: invention improves the security of protected objects.
