From the beginning of the XXI century mankind is experiencing the fourth Industrial Revolution Industry 4.0. This process is a massive introduction of cyber-physics systems, systems for processing and analysis of large data arrays, the use of InternetofThings in industry and automation, and widespread digitization [1]. InternetofThings closely connects various types and types of devices, enterprises, technology, mobile communications, etc. [2]. Such an association within the industry poses high requirements for safety, reliability, speed, uninterrupted work and protection of devices, as well as communication channels between them. On its own, high requirements apply when it comes to objects with critical infrastructure. The category of such include nuclear power plants (NPPs). In this article, a model for data transmission to a crisis center in the event of an accident is proposed. Also presented software and technical implementation of the proposed model. This work is devoted to the creation of a prototype of a software and hardware complex simulating the process of monitoring the NPP power unit. Software-hardware complex is a practical implementation of one of the proposed models of systems after emergency monitoring (RAMS). The development consists of two levels. At the lower level, which is the hardware level, there are sensors, microcontroller, hardware. At the upper level is the information system, which allows within the crisis center to get the values of indicators from the sensors in a convenient and visual form, to store, archive data. In addition, the crisis center has the ability to control the system stabilization of the power unit during an accident, for example, by switching on cooling devices. Data from the power unit can be quickly received by external experts (EEs) located in other countries of the world, without losing time to install software applications or specific software. Crisis center and a group of external experts take decisions on the elimination of the accident or through the usual situation. Due to the proposed model of data transmission, it is possible to obtain as much data as possible about the state of the accident for further liquidation. The article also presents the experimental part of the work.
