COMMUNICATION SUBSYSTEM OF CONTROL SYSTEMS OF UNMANNED AIRCRAFT UNDER EMERGENCY CONDITIONS

Background. The article is devoted to the construction on the basis of the principle of the hierarchy of the communication subsystem of a mobile telemedicine complex equipped with a heterogeneous group of unmanned aerial vehicles and functioning in emergency conditions. Materials and methods. Three levels of radio communication are proposed: the upper level corresponds to long-range (space) radio communication, with the means of which a mobile telemedicine complex is equipped, the middle level corresponds to medium-range radio communication, with the means of which an unmanned aerial vehicle is equipped, coordinating a flight task of a heterogeneous group of unmanned aerial vehicles and unmanned aerial vehicles of a heterogeneous group; the lower level corresponds to short-range radio communications, the means of which are equipped with an unmanned aircraft of a heterogeneous group and sedentary objects in the emergency zone. Structural diagrams are considered and characteristics of long-range, medium and shortrange radio communications are given. Results. It is shown that the proposed organization of the communication subsystem of a mobile telemedicine complex, equipped with a heterogeneous group of unmanned aerial vehicles and operating in emergency conditions, makes it possible to functionally distribute tasks solved by individual unmanned aerial vehicles of a heterogeneous group, and then integrate the results obtained. Conclusion. According to the authors, the construction on the basis of the principle of the hierarchy of the communication subsystem of a mobile telemedicine complex equipped with a heterogeneous group of unmanned aerial vehicles and operating in emergency conditions allows solving resource-intensive and complex problems in medicine and in the elimination of the consequences of emergencies.
