TECHNOLOGICAL INFORMATION COLLECTION SYSTEMS

The use of the outdated technological communication systems such as Iskra, currently in operation at gas and oil pipeline transportation enterprises does not allow monitoring the technological parameters of remote objects of communication systems and electrical complexes. The problem also lies in the need to ensure centralization and support of the network with the maximum degree of autonomy of operation. It is necessary to monitor, analyze emergency situations and manage safety, while reducing the volume of transmitted information. The purpose of the study is to develop an integrated automated distributed system for collecting technological information from gas industry facilities. Materials and methods. The algorithms are implemented in a program written in the C++ programming language for ATmega 328 microcontrollers. A practical test of the system’s performance was carried out at the facilities of the Cheboksary linear production communications center (hereinafter LPC) of Gazprom Transgaz Nizhny Novgorod LLC. Results. To implement the collection of technological information, the Modbus network protocol and the Atmega 328 microcontroller were selected. In order to increase the autonomy of the technological information collection system, the volume of transmitted information was reduced, the structure of the software package was developed and the program code was written. An interface connection of the existing communication equipment and the programmable microcontroller was made. Thus, the automated process information collection system was successfully implemented at the facilities of the Cheboksary linear production communications center of main gas pipelines. The decisions made based on the incoming information are transmitted in the form of control commands directly to remote actuators, ensuring the reliability of the entire infrastructure. Conclusions. The implementation of the proposed method of remote collection of technological information made it possible to ensure prompt adoption of measures to eliminate violations in electrical complexes and communication systems.
