AUTOMATED SYSTEM OF INDUSTRIAL OBJECTS CONTROL Russian patent published in 2016 - IPC E21F17/18 H04W64/00 

FIELD: communication.

SUBSTANCE: invention relates to control and communication and can be used in automated systems of control and monitoring, in particular for monitoring and determining locations of equipment and personnel, transmission of data, voice and industrial parameters in real time from terminal equipment. Automated system of industrial objects control comprises a ground part with a centralized control center and an underground part accommodating an equipment. Centralized control center of the ground part includes: a server or several servers, an automated enterprise control system (AECS) for centralized control, data collection, processing, display and archiving information on the object of monitoring, a network controller for control, configuration and diagnostics of the network elements and their interaction, a switch or switches of the main local area network (LAN) on the surface and media converters with intrinsically safe optical radiation. Underground part includes: one or several segments of an underground explosion-proof LAN built on the basis of explosion-proof Ethernet switches, a radio subnet or local radio networks (LRN), which via radio gates are connected with segments of the underground LAN. Each radio subnet has one or several radio gates connected to the same or different segments of the underground LAN, each LRN includes radio routers connected to each other and to the radio gates with wire interfaces RS-422 or via radio channel IEEE 802.15.4. Explosion-proof LAN segment switches are connected to each other and to at least one media converter and with the surface part by optical Ethernet interface 100 BaseFX with intrinsically safe optical radiation, the radio gate is connected to one of the switches with an explosion-proof LAN via an Ethernet interface 10 Base-T. System comprises: an explosion-proof power supply source of the intrinsically safe AC voltage of 12 V connected by means of an intrinsically safe power supply line with the voltage of 12 V with an explosion-proof accumulator source of the intrinsically safe voltage of 12 V and an explosion-proof power source of the intrinsically safe DC voltage of 45 V.

EFFECT: invention allows providing the possibility of determining locations of industrial equipment and its service personnel with provision of a secure access over the Internet.
