A comparative analysis of the possibilities of using woven composite materials with specified sensory properties as information and measurement systems of the industrial Internet of Things (IIoT) is presented. It is proposed to consider such woven sensor systems as a basis for building a network interaction environment for components of wireless wearable sensor networks, as well as systems for monitoring the stress-strain state of products made of woven composite materials. To impart sensory qualities to such multilayer 3D fabrics at the stage of their development, it is proposed to modify their structure by introducing threads, on the one hand, having the properties necessary for the formation of data transmission channels, and on the other, being piezoelectric sensors, whose signals allow monitoring the dynamics of changes in the stress-strain state of a woven composite material.The release of a functionally augmented 3D fabric in this way opens up real prospects for conducting a full-scale experiment to study the sensory properties of spatially extended products made of woven composite materials.

In the oil industry, autonomous electric power sources containing renewable energy sources are used to power remote consumers with an occasional load, mainly valve assemblies on pipelines. The need for electric energy sources of this type is determined by the need to install valve assemblies at pipeline intersections with water barriers, at intersections with transport arteries, and in a number of other cases. Very often in such places there are no available power lines or substations. In this case, the only alternative is the use of autonomous sources, or the expensive construction of an extended overhead line. In some cases, the developer decides to abandon the overhead line due to its high cost and the need for additional land acquisition. From the point of view of ecology, such a decision in favor of autonomous sources of electric energy also has an additional positive effect. Since the installation of valve assemblies is dictated mainly by environmental considerations, high requirements are placed on the reliability of power supply. Violation of these conditions can lead to hydraulic shocks in the system and possible destruction and breakage of system elements. A wind turbine or solar panels are undoubtedly an independent source of power supply and, when paired with batteries or a diesel generator set, can formally provide high reliability of power supply. On the other hand, there are periods of time when the power of a wind turbine or solar battery is insufficient to supply a given load. As a consequence, the decision on the reliability of power supply should be made on the basis of additional studies of the static and dynamic stability of the entire electrical power generation complex.
