FIELD: information technologies. ^ SUBSTANCE: system is developed, in which in case of various development of emergency situations in the field, resulting in disturbed communication, communication is automatically recovered between technological objects of the lower level of the system hierarchy, and also an automatic changeover is carried out to reserve radial and reserve circular optic fibre communication systems (OFCS), which does not result in loss of communication between system objects, at the same the system provides for the possibility to arrange control of field equipment, both from the main node station and from a control node station, and also from any of the node stations. In the system faulty communication lines are identified, on the basis of which failed OFCS are repaired. The multi-level distributed OFCS provides for reliable uninterrupted high-speed control of process equipment and meets requirements of safety for hazardous technological processes of gas-condensate mixture production and transportation for its processing. ^ EFFECT: development of a reliable multi-level distributed optic fibre communication system. ^ 6 cl, 13 dwg |
