Abstract
Relevance. The need for intelligent video surveillance is due to the lack of control over the situation at unguarded crossings. For this purpose, it is proposed to use a 4G standard system in the frequency range from 1785 to 1805 MHz allocated to Russian Railways.
Objective: to create a model that allows us to study and simulate the dependence of attenuation on the communication range for intelligent video surveillance systems at unguarded railway crossings.
Methods: using the COST-231 Hata mathematical model based on empirical relationships that take into account the type of terrain, the frequency of the radio signal, the size of objects blocking the route, the distance between them, as well as the heights of base station masts and mobile subscriber antennas.
Results: the obtained refined expression of the model for the conditions under consideration determines the dependence of attenuation on the radio channel route on the distance between the base station and the user equipment of video surveillance platforms based on 4G networks for unguarded crossings located on a section outside urban development. The model takes into account the driver's reaction time and the length of the braking distance for rolling stock of various types.
Practical significance: the results of the work can be used in the design of video surveillance systems on railway transport at unguarded crossings, taking into account the speed of trains on the section under consideration.
