Research On Key Techniques Of Radio Resource Allocation In Relay-enhanced Cellular Networks

In order to alleviate the contradiction of Strong demand and backward managemen in Chengdu dangerous chemicals market, the most important thing is to strengthen safety supervision of dangerous chemicals producing, storage, using, operation, transportation by using advanced technologies. In this paper, research subject is the designing and realization of safety supervision system of dangerous chemicals. By using sound, video, light, temperature, pressure, smoke, RFID and other Internet of things technologies, the safety supervision system monitor the operational status of hazardous chemicals continuously and in real time, achieve the purpose of greatly improving the efficiency of safety supervision.The main research contents is divided into six parts: The research background and significance of the safety supervision of dangerous chemicals in Chengdu City market; The requirement analysis of the safety supervision system of dangerous chemicals in Chengdu City; The design of the safety supervision system of dangerous chemicals in Chengdu City; The implementation of the safety supervision system of dangerous chemicals in Chengdu City, including the implementation of video monitoring based on sensor, real time monitoring, data analysis and early warning based on GIS, equipments and major hazards management, safety supervision of law enforcement, information delivery; The test of the safety supervision system of dangerous chemicals in Chengdu City; The application research of the safety supervision system of dangerous chemicals in Chengdu City; Summary and Outlook.Through the theoretical research and practical application, it has achieved good economic value and social benefits, and provide the basis and technical support for the safety supervision of dangerous chemicals in Chengdu City.
