Research On The Construction And Evaluation Of Emergency Logistics Information System Based On The Internet Of Things

The7magnitude earthquake occurred in Lushan County of Ya’an City Sichuan eight two on April20,2013,3hours later, the rescue of7times Yushu earthquake was mobilized to the forth strength. The national relief system substantially rebuilt after the Wenchuan earthquake, was showing the timely response and strong ability to mobilize; examined by Yaan earthquake, The country’s emergency response capacity had been greatly improved. Since disaster localities was much in the mountains, often leading communications power outages, road houses destroyed, the disaster situation was difficult to grasp at the first time, so it was difficult to carry out emergency relief work. When disasters happened, the emergency logistics information system based on Internet of things could play a significant role in the whole disaster relief, for instance, urgent and co-ordination dispatching food、 water、medicines、tents and other supplies; summary reporting disaster situations; optimal scheduling emergency vehicles; optimal planning the way forward and so on. When these emergency logistics work was quickly and efficiently carried out in a disaster, it provided good protection for a series of disaster reduction、rescue victims、reconstruction and so on.In this context, the paper mainly discusses how to construct the emergency logistics information system based on Internet of things, and researches the evaluation of the overall information system. The planning、analysis、construction、implementation and evaluation of emergency logistics information system based on Internet of things are discussed one by one.First of all, this paper summarizes the research achievements of predecessors, generalizes and reviews of the previous research papers. Based on the current research status, the overall planning for the emergency logistics information system based on Internet of things is given; the construction goal of information system is put forward, and the system’s technical、economic social feasibility and necessity is analyzed. At the same time, the preliminary investigation and analysis are done to the running situation of the current information system.Second, The information system is analyzed in detail in paper, starting from the needs and functions of information system, the information system of business process is analyzed too. Combining with the system requirements and business process, the system’s overall view and four layers architecture diagram are given; the system running environment and the corresponding development models and tools are studied. Later, each subsystem and the function module of the system are divided and elaborated, and the code is designed. On the basis, the concept、the logical and physical model of database are designed, and the database subsystem is carried out, achieving the goal of the overall building of information system.Finally, the paper discusses the implementation and security factors of the information system, four suggestions are put forward. By choosing scientific and reasonable evaluation method and index, the author makes an evaluation of the information system; And three actual emergency logistics information system are selected to evaluate, then the results of the evaluation are given. In addition, six constructive views are put forward to the emergency disaster relief itself, expecting to offer reference to the improvement of our Country’s emergency logistics.
