The problem of formation of complex approaches to hardware realization of engineering and technical methods of prevention of emergency situations owing to a fire on potentially dangerous objects in the conditions of damage of power supply of systems of emergency counteraction is considered in the work. The analysis of warning methods used to detect emergencies due to fire at potentially dangerous objects proved that in specific operating conditions, namely damage to the power supply of emergency response systems, known protection methods (hazard identification as its initial stage) are ineffective. At the same time, the use of alternative methods, such as methods based on the phenomenon of acoustic emission, despite their proven ability in other areas of public safety, remains highly questionable because at present there is no appropriate mathemati-cal apparatus on which to form algorithmic and procedural basis. these innovative approaches. It is to solve this urgent problem, the formation of the mathematical apparatus of engineering and technical methods of emergency prevention due to fire in the event of damage to the power supply of emergency response systems, and the above research is directed. Based on the above, the purpose of the study is to form integrated approaches to the hardware implementa-tion of engineering and technical methods of emergency prevention due to fire at potentially dangerous objects in the event of damage to the power supply of emergency response systems. To ensure this goal, the following tasks are solved: the sequence of stages of processing acoustic signals is determined; the general requirements to hardware realization of engineering and technical methods and the gen-eral functional scheme of practical realization of the demanded approach are formed. During the research the sequence of the main stages of processing of acoustic signals from the source of an emergency situation as a result of a fire at a potentially dangerous object is generalized and determined. The general requirements to hardware realization of engineering and technical methods of the prevention of emergency situations owing to a fire on potentially dangerous objects in the conditions of damage of power sup-ply of systems of emergency counteraction are formed. The general example of realization of the functional scheme of engineering and technical methods of preven-tion of emergencies in energy difficult conditions of functioning of potentially dangerous object is considered. Recommendations concerning a possibility of application of required methods in practical activity are resulted. Keywords: emergency situation, engineering and technical methods, acoustic signal, emergency power sup-ply system

The paper considers the problem of accidental destruction of power lines due to external factors, which led to the de-energization of large areas for a long time. Breakdowns can be caused by both mechanical damage and natural disasters - floods and earthquakes and more. As a rule, as a result of an emergency situation, the level of energy supply of large areas decreases. An important methodological aspect in studying the quality of the electrical network is the allocation of hierarchical levels of consideration. Thus, the authors consider the lowest level of functioning of the electrical network, namely the power supply of the emergency response system. Such circumstances, in turn, can lead to the emergence and development of emergencies that lead to significant casualties and destruction. It has been established that some accidents have led to power outages for more than one day. The analysis of features of work of emergency counteraction systems which are used on objects in the conditions of damage of electric networks is carried out. Devices of emergency counteraction of domestic production which have found wide application on objects and continue to be improved and let out are considered in work. Approaches to the use of imported emergency response devices, in terms of operation and installation, are almost the same, as they must meet the requirements of those regulations that are used in Ukraine. It is established that redundancy of power supply of such systems at the expense of rechargeable batteries allows to carry out their uninterrupted work no more than 24 hours. That is, if the power supply of emergency response systems from the traditional power supply network is not restored within 24 hours, such systems will stop working, which may lead to an emergency becoming an emergency. Thus, the further work of the authors will be aimed at finding a way to back up emergency response systems in the event of a power outage from the traditional power grid for a time exceeding the possibility of power supply from the battery. Keywords: emergency destruction, emergency, power grid, emergency response systems, backup power supply.

Kasus kebakaran di Rumah Sakit masih tergolong tinggi dan ini sangat merugikan baik untuk pihak Rumah Sakit maupun pengunjung atau pasien yang berobat. maka diperlukan sistem tanggap darurat yang baik dalam menghadapi situasi darurat terutama kebakaran, maka dari itu tujuan dari penelitian ini adalah untuk mengetahui sistem tanggap darurat kebakaran serta bagaimana implementasi prosedur operasional tanggap darurat (emergency response and preparedness) Rumah Sakit 3M Plus. Jenis Penelitian ini adalah observasional dengan pendekatan kualitatif analitik. Analisa yang digunakan adalah triangulasi sumber, metode dan data. Data yang disajikan dalam bentuk matriks dan narasi. Hasil penelitian menunjukkan bahwa sistem tanggap darurat seperti simulasi kebakaran, sarana penyelamatan, dan kesesuaian penerapan APAR masi perlu dievaluasi dan perlu dibenahi kembali agar menjadi sebuah tindakkan yang tepat sewaktu terjadinya kebakaran. Serta masih ada beberapa yang belum sesuai dengan Standar Nasional Indonesia (SNI) maupun permen PU. Sistem proteksi pasif seperti titik kumpul, pintu darurat, tangga darurat tidak memadai. Fire cases in the hospital are still high and this is very detrimental to both the hospital and visitors or patients who seek treatment. Therefore, a good emergency response system is needed in dealing with emergency situations, especially fires, therefore the purpose of this study is to determine the fire emergency response system and how to implement emergency response and preparedness procedures for 3M Plus Hospital. This type of research is observational with a qualitative analytic approach. The analysis used was the triangulation of sources, methods and data. Data presented in the form of a matrix and narrative. The results showed that emergency response systems such as fire simulations, rescue facilities, and suitability of the application of APAR still need to be evaluated and need to be reorganized so that they become an appropriate action when a fire occurs. And there are still some that are not in accordance with the Indonesian National Standard (SNI) and PU candy. Passive protection systems such as gathering points, emergency exits, emergency stairs are inadequate.

The paper proposes the development of new approaches to the creation of emergency response systems using non-traditional power supplies in the event of damage to traditional power supply systems.The main idea of the work is the formation of integrated approaches to alternative methods based on the phenomenon of acoustic emission (AE) using an unconventional power source based on film solar cells on flexible substrates. The creation of photoconverters based on thin films from a variety of materials and compounds is a promising direction in the development of solar energy. Unfortunately, the efficiency of these photoconverters is not yet high enough, but the cost of equipment for their creation, and hence the cost of instrument structures, is already quite acceptable.The investigated solar cells were obtained by the method of thermal vacuum evaporation using a UVN67 vacuum unit with modified internal equipment.After manufacturing, solar cells (SCs) were investigated under standard laboratory conditions adopted for the study of solar cells for ground-based use, i.e. in the AM 1.5 mode with a luminous flux power of 100 mW / cm2 and a temperature of 25 ° C. To study degradation processes in such solar cells after measuring the initial parameters The solar cells were placed in a sealed plastic box and kept for 4 years at a temperature of 15-25 ° СChecking the elements demonstrate high degradation resistance, which provides general requirements for the material and the conditions for its creation promising for use as unconventional sources of power supply for emergency response systems and ensuring the use of information and technical methods for preventing emergency situations as a result of fire in conditions of damage to the power supply of emergency response systems.

The paper addresses the problem of increasing transportation safety due to usage of new possibilities provided by modern technologies. The proposed approach extends such systems as ERA-GLONASS and eCall via service network composition enabling not only transmitting additional information but also information fusion for defining required emergency means as well as planning for a whole emergency response operation. The main idea of the approach is to model the cyber physical human system components by sets of services representing them. The services are provided with the capability of self- contextualization to autonomously adapt their behaviors to the context of the car-driver system. The approach is illustrated via an accident emergency situation response scenario. “ERA-GLONASS” is the Russian state emergency response system for accidents, aimed at improving road safety and reducing the death rate from accidents by reducing the time for warning emergency services. In fact, this is a partially copied European e Call system with some differences in the data being transmitted and partly backward compatible with the European parent. The principle of the system is quite simple and logical: in the event of an accident, the module built into the car in fully automatic mode and without human intervention determines the severity of the accident, determines the vehicle’s location via GLONASS or GPS, establishes connection with the system infrastructure and in accordance with the protocol, transfers the necessary data on the accident (a certain distress signal). Having received the distress signal, the employee of the call center of the system operator should call the on-board device and find out what happened. If no one answers, send the received data to Sistema-112 and send it to the exact coordinates of the team of rescuers and doctors, and the last one to arrive at the place is given 20 minutes. And all this, I repeat, without the participation of a person: even if people caught in an accident will not be able to independently call emergency services, the data on the accident will still be transferred. In this work intended to add some information about applying system project in Uzbek Roads especially mountain regions like “Kamchik” pass. The Kamchik Pass is a high mountain pass at an elevation of 2.306 m above the sea level, located in the Qurama Mountains in eastern Uzbekistan and its length is about 88km.The road to reach the pass is asphalted, but there are rough sections where the asphalt has disappeared. It’s called A373. The old road over the pass was by passed by a tunnel built in 1999. On the horizon, the snow-capped peaks of the Fan Mountains come into view. The pass is located in the Fergana Valley between the Tashkent and Namangan Regions.
