FIELD: information technologies.
SUBSTANCE: invention may be used for redundant local networks used in one or several complicated industrial objects, for instance marine moorages for shipment of carbohydrates. Specified local network is arranged in the form of ring, one part of which is mounted on stationary part of object, and another one - on its full-circle part, with formation of two points of manifold break, one of break points is arrange din the form of optical fibre rotary connector, and the other one - in the form of radio access system, at the same time specified local network comprises manager of redundancy, which connects or disconnects ends of network manifold when errors are detected or not detected in the network.
EFFECT: invention provides for the possibility to build reliable redundant local network at several objects or in object made of stationary and full-circle parts.
