THE MONITORING SYSTEMS OF THE TEMPERATURE OF THE ETERNAL FROZEN SOILS
(pp. 54-59)

Abstract. This article describes the problems of functioning of the railway and oil and gas complex in the territories of permafrost soils under the influence of geocryological processes in the soil. For monitoring and control of these processes are considered technical tools and options for enterprises in the system, such as temperature sensors multizone digital MDTS 0922 with the possibility of periodic operational monitoring by the controller PCDS-1/100, continuous monitoring in realtime using controllers SCDS-1/100 and SCDS-6/200 and Autonomous monitoring using loggers LDS-1/100 SD and LDS-1/100 RM. Example use of this equipment at the facilities of LLC “Gazprom dobycha Nadym”. Developed a monitoring system of the temperatures used for field determination of soil temperature according to GOST 25358–82 where required to obtain data on the temperature of frozen, freezing soils. The implementation of technical solutions allows to increase the measurement accuracy and reliability, to simplify the existing system of monitoring temperatures, to expand their applications. The developers of JSC “NPP “Etalon” attempted to eliminate the disadvantages of the known systems for monitoring temperature, such as complexity, high cost, low accuracy and weak tightness that lead to failure of devices in industrial applications. The architecture of the developed measuring system is very flexible and allows, depending on the tasks to implement online, offline, or continuous monitoring of the temperature of the soil under the foundations of buildings and structures, along the roadbed of Railways, etc., thereby ensuring the health and safety of functioning of objects in the permafrost.

Keywords: permafrost, longterm changes, monitoring, soil temperature, trend, multizonal gage, controller, system.
