It’s suggested to adjust the existing normative documents, in particular the first version of GOST R 8.596-20xx “State system for ensuring the uniformity of measurements. Metrological assurance for measuring systems. Main principles”. The aim of the proposed adjustment is to legitimate the nuclear power plants complex measuring systems application, taking into account their peculiarities in the sphere of state regulation of ensuring the unity of measurements. Generally complex measuring systems possess all features of the adaptive and intelligent measuring systems, which parameters and algorithms can vary during operation. Therefore, it is proposed for adaptive and intelligent measuring systems and for branched measuring channels, to provide the possibility of dividing into separate measuring components without the whole system or channel approving. The systems and channels measuring components are proposed to be considered as approval measuring instruments, which interaction is regulated by certified measurement techniques. When selecting the boundaries of the measuring system or channel, it is proposed to provide the possibility to be guided by the reasonability of the sorting the technical means or operations involved in parameter control as metrologically significant. In addition, it is proposed to introduce a statute that allows to avoid the type approving of the "degenerate" systems consisting of one or more simple channels formed only by the measuring means.

Use of the technical (computer) vision systems for Earth remote sensing is considered. An overview of software and hardware used in computer vision systems for processing satellite images is submitted. Algorithmic methods of the data processing with use of the trained neural network are described. Examples of the algorithmic processing of satellite images by means of artificial convolution neural networks are given. Ways of accuracy increase of satellite images recognition are defined. Practical applications of convolution neural networks onboard microsatellites for Earth remote sensing are presented.

This article presents the rationale and methodology for developing an intrinsically safe device, namely, a hydrostatic fiber optic sensor with a position-sensitive detector for monitoring the level of oil products in large-capacity tanks at oil depots and during pumping in a raw material warehouses. This device suitable for continuous monitoring of the liquid level, based on the measurement of a hydrostatic column of liquid with automatic offset of changes in the density of the liquid. Offset is carried out by means of a displacer (a fully submerged float), inside which a housing with a position-sensitive detector (PSD) is integrated. Theoretical validation of the bellows suspension usage for a displacer is given. During filling a container with a liquid whose level is measured, liquid hydrostatically applies pressure over the entire effective area of the measuring bellows, the movement of which is recorded by an optical triangulation sensor using the reflected infrared ray incident on the bottom of the bellows. The principle of the triangulation sensor operation is based on the geometric properties of the triangles. The pulses of infrared radiation come through a fiber optic cable. In order to measure the movement of the surface (the bottom of the bellows) by measuring the movement of the reflected beam, a position-sensitive detector is used, which is located in a remote controller. In this device for the intrinsic safety problem solution, optical inputs of a fiber optic flat cable are located in the active zone of the sensor, which is connected to the optical inputs of a position-sensitive detector, operated on the principles of photoelectric effect. The light spot moving along the sensitive zone and converted by the detector into a one-dimensional signal proportional to the distance to the object.
