The process of construction of the computer systems of the fire warning is the research object. The aim of the thesis is an increase of efficiency of work of the fire warning by perfection of the off-wire computer systems of the fire warning due to the development of new models, methods and components of such systems on the base of ZigBee technology. A mathematical vehicle, which is based on the methods of theory of automatic control, theory of the oscillating systems with the concentrated parameters, theory of electric chains, methods of electroanalogies, theory of algorithms and also theory of decision of tasks of placing and coverage, was used. Practical value of the obtained results is: 1. The practical value of work consists in leading by the competitor's scientific positions to the concrete engineering decisions, that allowed construction and experimental verification of pre-production models of the computer systems of the fire warning and their components. 2. The worked out methods of construction of topology of computer networks of the fire warning allow shorten time on determination of fact of fire to 40 %, and also decrease the amount of radio centers in the computer system on 36-54 %. 3. Application of the offered schematic and functional design of blocks of the computer systems allowed work out typical radio centers on the base of the ZigBee modules with an autonomous feed with the use of piezoceramic primary transformers of the fire warning (PPTFW). 4. The software products (with the use of the object-oriented programming languages), which allow to design the topological structures of the computer systems of the fire warning on the base of ZigBee technology, are worked out. 5. The calculations on the example of construction of the off-wire signaling for the 11th corps of the Black Sea State University named after Petro Mohyla in Mykolaiv, showed that the use of the solutions offered in-process allowed to save to 14 % dedicated financial resources. Novelty of scientific results of the dissertation: 1. The method of construction of topology of computer networks from ceiling (PPTFW) due to the application of check point, double decision of task of placing taking into consideration the different types of components of network, that allows to build the topology of computer networks from ceiling and wall PPTFW with the use of wireless technology of communication of ZigBee data, got further development. 2. The method of construction of topology of computer networks from ceiling and wall PPTFW for the construction of single network within the limits of one the apartment, which has two realization at the stage-by-stage construction of ceiling, and then wall transformers and at their simultaneous placing, what the amount of radio centers of computer networks of the fire warning allows decrease, has been firstly worked out. 3. The method of sensing of maximum ranges between radio components of wireless computer network on the basis of application of radial models due to the development of method of surplus of multibeam models with approaching the difference of powers of signals to the set value, that allows to dispose the radiocomponents of computer network on distances with the assured connection between them got further development. 4. The schematic and functional design of blocks of the computer systems, in which the design of primary transformer comes true at the functional level, and microcontroller part - at the schematic and functional technology, what allows to simplify the process of design of blocks of the computer systems of the fire warning, is first offered and investigational. Scientific positions, conclusions, suggestions and recommendations, which are expounded in dissertation, articles and other publications, can be used for creation of the computer systems of the fire warning on the base of ZigBee technology, and also in the educational process at preparation of specialists of technical specialities.
