Abstract
In this paper, an LED screen with ultra-low power consumption is developed. The work proposes methods for modeling mechanical and electronic systems. The combination of these scientific works gives us an opportunity to reduce power consumption. Spatial-mechanical sweep is developed, which allows to refuse decoding circuits, which in turn consume 35-40% of the total power consumption. We studied the setup of SDRAM controller for reading video data stored in memory or entering data into memory, and developed a code for reading data from the controller memory and outputting it to the data bus on demand of the output device. The results of this study can be widely used by the system for the integrated operation of the evacuation information system in training mode in order to train and mobilize personnel responsible for evacuation, as well as to keep all information and communication resources in readiness.
