[Abstract]:In order to secure a safer production environment, the supervision of safety production should always ensure the safety of the people's life and property, maintain social stability, promote the healthy, rapid and sustainable development of the national economy as the primary task and purpose, in order to improve the level of safety management as far as possible. Under the big background of spheroidization, the supervision and management of safety production will continue to face new problems and new situations. Therefore, how to realize the dynamic supervision and management of production safety in our province and in our country and to innovate the management mode suitable for the national conditions of our country have become an urgent problem to be solved. The planning of emergency rescue route is an urgent problem to be solved in order to guide the efficient allocation of relief materials, effectively carry out emergency rescue and reduce the casualties and property losses to the maximum extent. In general, explosion is the most serious case in the accident, so the impact range of the explosion must be calculated and analyzed. In the event of an accident, it is important to get a correct and feasible route to the location of the accident. However, it is very difficult to find a most convenient path because of road construction, traffic accidents, rush hours, and other unpredictable factors. Therefore, how to choose a convenient and efficient rescue in the disaster period. It is an urgent problem to be solved for the arrival of fire vehicles in the disaster period, the delivery of relief materials and the arrival of the rescue experts, which is an urgent problem to be solved. This paper focuses on the problems that need to be solved in the supervision and emergency rescue of major hazard sources at home and abroad, focusing on the major hazard sources based on the cloud environment. The optimization and decision of the emergency rescue route are studied, including: (1) clarifying the concept of emergency cloud, analyzing its organizational characteristics, service mode, and explaining the advantages of the new ICT environment to the operation of the emergency cloud, and making certain analysis on the definition of emergency cloud services, organization mode and emergency cloud, and putting forward the results. The service mode needs to be provided, and the service content and operation process under this model are explained in detail, and the related contents of the operation process and the advantages of organizational change are discussed and analyzed. (2) research on the influence range and the distribution of the stress field of the unclosed space combustible gas cloud explosion disaster, and the non enclosed space combustible gas The distribution law of stress field produced by gas cloud explosion is derived, and the stress values of different locations in different sizes of gas clouds are calculated by programming independent equation solver. (3) through the gas cloud model established in this paper, the influence of the explosion of flammable gas clouds under the obstacle conditions is systematically studied. The distribution of range and stress field, the change of pressure field in the explosion process and the distribution of pressure variation at the external plate barrier are described. The relationship between some obstacles in the gas cloud and the explosion strength is discussed. The computer soft parts are compiled and the distribution of the maximum pressure field of the open space explosion is distributed. And compared the calculation results under the condition of the explosion field in the air cloud. (4) the study of the emergency rescue route and optimization algorithm in the period of disaster. A method to judge the real time road condition is designed, and the three positioning navigation techniques of GPS, GIS and GPRS are used as technical support to monitor the driving condition of the rescue vehicle and convert it into data information. The monitoring center receives, filters, analyses, and makes a reasonable judgment on the road conditions at that time. In view of the shortcomings of the Dijkstra algorithm, the selection and optimization algorithm of weighting coefficients under each road condition are proposed. Under the premise of ensuring accuracy and reasonable accuracy, the process of searching the optimal path can be simplified. (5) the importance of the cloud environment is important. Study on the optimization and application of emergency rescue route in the period of dangerous source disaster. Taking Huainan as the research object, the construction of emergency rescue command system for major hazard sources under the cloud environment in Huainan is discussed in detail. The emergency platform system for Huainan safety production is designed and realized, and the basic principles should be met in the implementation process of this system. The contents of the standard and construction were studied in depth. And the software was compiled according to the research results, which provided a guarantee for the safety production of Huainan. The research results effectively realized the emergency rescue command in the period of heavy hazard in the cloud environment, and provided the security for the enterprise production safety under the new situation.
