Abstract: Using the analysis of the advantages and disadvantages of a previously developed split-system-fire detector model, in which thermoelectronic protection modules, smoke and gas sensors are installed that detect dangerous fire factors and leakage of household gas, the need to use multi-split systems with two or three internal units is proved one of which is mandatory installed in a room with gas appliances (oven, gas heating installation, etc.) and is combined with a gas meter having an electromagnet A thermomagnetic separator of air (TMSA) is installed in each indoor unit, which separates and removes oxygen through the drain hose to the outside, and returns inert gases (nitrogen, carbon dioxide, etc.) to the room, which ensures explosion prevention or fire suppression. The novelty lies in the use of TMSA, protected by the patent for invention RUS 2428242, to suppress the dangerous factors of fire and explosion (FEPD) in case of leakage of household gas. The results indicate the effectiveness of the use of multi-split systems modified in this way, for their fire and explosion protection.The value of the proposed modernization lies in the massive use of split-systems, which allows to radically solve the problem of fire protection of the residential sector.

Abstract: The object of the research is the mobile networks. The subject of the research is the algorithms that allow to determine the optimal location of base stations, as well as such equipment capacity that will be enough to serve subscribers with an acceptable level of overloads and other requirements for quality of service. The goal is to design the network in terms of the criterion for minimizing the cost of all network elements, taking into account the expected number of subscribers and traffic. The specificity of the objective function and its arguments, as well as constraints, allows to define the problem under investigation as a conditional optimization problem and apply the tools used in these cases to solve it. As a result, a generalized algorithm for solving problems of structural synthesis for systems whose distinctive feature is the presence of mobile subscribers and base stations that service them by receiving and transmitting a signal is described. A comparative analysis of existing approaches to solving the problem allowed us to formalize the objective function and limitations. The usefulness of the results is the possibility of their use (after the implementation of algorithms for solving the problem) for the design and implementation of modern mobile communication systems.

Abstract: In this article the transformations model the split-systems-firefighters of the announcer is presented to the automated installation fire and explosion protection of the apartment / an individual house. The offered approach uses aspiration properties a Split system (room air course where the internal block is installed) that allows to carry out early detection of dangerous factors of the fire (smoke) and explosion (leak of household gas), at installation in the internal block of the smoke fire announcer with the GSM module and also the sensor which finds leak of household gas in the individual house. The methodology of "transformation" consists in installation in the internal Split system block of a thermomagnetic separator of air (TMSA), and on a gas pipe of the apartment - the gas meter with the built-in sensor and the electromagnetic valve which blocks supply of gas on a signal of the built-in sensor and also at operation of the gas sensor in the internal block a split system. The novelty will be that at detection of dangerous factors of the fire and explosion in the apartment or in an individual house, the notification of the relevant services and TMSA which deletes oxygen from premises on the street joins, leaving nitrogen, than suppression of fire and dilution of the explosive environment is provided.

Abstract: The subject of the paper is the infrastructure of air traffic management and control of airspace usage by small and unmanned aircrafts in the lower segment of the airspace classes C, G. The development of unmanned aircrafts and the lack of technical means of monitoring and identification of small aerial vehicles shows the need to find new solutions to ensure the safety and efficiency of flying at low altitudes. Analysis of air navigation and ATM development history shows that the modern stage is characterized by the use of the dependent surveillance system based on the transmission of the aircraft coordinates by the on-board GLONASS/GPS equipment.  A comparative analysis study of the effectiveness of electronic communication networks and telecommunications, data-communications and receiving/transmitting equipment using dependent surveillance for small and unmanned aircraft is performed with the goal of creating a modern air navigation, ATM and communication system at low altitudes. Low carrying capacity and energy efficiency of the light aircraft necessitate the use of  low power and low weight equipment. This in turn generates new requirements for the radio technical air support systems.  The study determined that out of existing satellite systems, aviation technology and mobile digital cellular communications, the mobile GSM/GPRS communication system is more efficient and effective.  The novelty of the article: a set of technical and regulatory conditions allowed the author to develop a method of air traffic management based on GLONASS/GPS equipment and GSM/GPRS communication networks in airspace classes C, G.

Abstract: The research subject is the system of management of a machine tool hydraulic system used for hydraulic drive power supply of metal-cutting machines. The article contains the results of simulation modeling of the system in the MathLab software package and analyzes the transitional processes of these models. The authors show that the quality if a hydraulic station management determines reliability and productivity of a particular cutting unit. This problem is especially topical for cutting machines with computer numerical control used for deep-hole drilling with carbide drills within the wings for cutting oil input. Cutting oil input through the cutting zone in many aspects depends on the presence and the condition of chips in drill channels in the function of embedding (to 9d). The authors perform the simulation of pump performance management in the function of changing consumption using the MathLab modeling, since when achieving the critical pressure of 65-70 MPa, forced ejection of a drill from a cutting zone is necessary, and sometimes it is impossible to perform in reality. The authors propose simulation models, which help analyze the hydraulic station performance without technological equipment. The article considers the system of a hydraulic station management on the basis of micro PLCs Siemens S7-224XP. The authors analyze the management subsystem for a controller realizing the temperature control and cutting oil consumption law.

Abstract: The research subject is the methods and means of creation of computerized process control systems of especially dangerous industrial objects (CPCS EIO). Such objects are controlled with special safety requirements, which are described in technical regulations and safety guidelines, which are obligatory for especially dangerous industrial objects. If the EIO projects undergo state expertize for compliance with such requirements and guidelines, CPCS’s compliance with them is only confirmed by the protocol between economic entities based on the testing methodology composed by them. Using he example of computer-aided engineering systems, the authors of this work develop the methodology of automation of creation of CPCS EIO, which guarantees implementation of the above mentioned safety requirements and guidelines. The scientific novelty of the study consists in, firstly, the development of a method of description of dynamic links of engineering and technical models of elements of an object, which optimize the performance of technical processes in controllers; secondly, the creation of a software and hardware complex of simulation of an object of automation, which helps realize virtual implementation of a CPCS EIO without an object to test the effectiveness of the required security facilities.

Abstract: The research object is a robot designed for work as a part of mobile systems, and execution of tasks, involving hazardous factors, such as explosive objects removal and disposal, nuclear works or works in aggressive chemical and biological environment. Among a variety of types of mobile robots, wheeled ground mobile robots are of a particular practical interest nowadays. At the present time, a new stage of robotic technology and automatization, based on micromechanics and nanotechnologies, is developing; there is a real opportunity to significantly increase the adaptability of automatized and automatic systems, and extend the sphere of their application. Robots are controlled by the system of independent control of left and right wheel turn. The scientific novelty consists in the method of detection of suspect objects (obstacles) and the robot’s coordinates, and, consequently, the coordinates of the suspect object, by the robot. A suspect object is detected and identified as a hazardous object with the help of an infrared sensor reacting at the obstacle. Robots are controlled by automatic controlled systems.

Abstract: The authors consider the problems of organization and functioning of transport and energy infrastructures, inflicting the most significant socio-economic losses both in Russia and abroad. The results of the system research allow assuming that if the “technological progress products” inflict losses on the nature and the individual, it means that some person or a group of people (designers, law-makers, managers, officials, etc.), interested in the development of such products or just not knowing about the damage, is behind such a product. The research methodology is based on the models of transport and heat-power engineering emissions; their correlation with the global warming model is evident. However, using thermodynamics and molecular physics for the interpretation of modeling results, the authors prove that climatic cataclysms are caused not by the “greenhouse effect”, but by the atmosphere volume growth due to the “geosphere burning out” (the recovered hydrocarbon fuel) and the wastes dispersing in the atmosphere. The scientific novelty of the study consists in, firstly, the development of bio-tunnels, implementing nature-like technologies of wastes absorption and the restoration of the burnt out oxygen, secondly, in the development of adaptive systems of transport and energy infrastructures management according to the functions of production of the entropy, restoring three nature oxygen, water and carbon cycles, and thirdly and most importantly, in the creation of adaptive taxation systems, allowing creating the proposed synergistic systems.

Abstract: The subject of this research is the quality of fireproof surfaces (FS), technological processes of their production and control, as well as means of controlling the longevity of FS materials and units on location. The goal of this research is to optimize the quality control over the FS during production and development of a model of portable automated complex (PAC) that would allow determining the stage of “aging” of FS on location. The work also presents a synthesis of an online system of communication between objects, volunteer fire departments and supervisory authorities for insuring fire safety during use of materials and constructs with FS. Based on the systemic analysis of the existing fire safety products made from wood, metals, resins and polymers, the authors develop methodology for determination of fire resistance of samples with FS using baro-electro-thermo-acoustic analyzer and create “samples” for further diagnostics of their aging on location. The novelty of this research, protected by a patent registered in the Russian federation, consists in development of PAC, which allows determining the stage of “aging” of FS on location, as well as the model of online system of communication between objects, volunteer fire departments and supervisory authorities for insuring fire safety during use of materials and constructs with FS.
