Abstract. Analyzed the scope and types of automated information systems containing subsystems of the "measuring sensor -element processing". On the basis of the Queuing theory a model of evaluating the properties of information flow in the subsystem. The time spent by the sensor data generation and processing time of the output data array to the processing elements described by an arbitrary distribution law. Using little's formula the analytical solution allows to estimate the required level of performance of the subsystem. The research of the obtained solution in the range of parameters of interest. On the basis of General theoretical solutions identified four private practical case, different values of the coefficients of variation of information flows.

Abstract.A general structure of an automatic fire detection system and the results of a study video analysis algorithms for detecting based on contour analysis. Given contour extraction processes objects in the image and make decisions about the discovery of fire or the absence thereof. Experimental researches on the video images of the forest area done with the use of the developed structure of the automatic fire detection system.
