Abstract
Abstract. Aiming at the problem that the existing methods of collecting and processing information of potential location safety hazards in scenic spots can not identify and analyze real-time potential hazards quickly and accurately, a real-time method and system of collecting and analyzing information of potential location safety hazards for tourists in intelligent scenic spots under the environment of Internet of Things is proposed.The set of method and system includes: collecting geographical coordinate information of potential safety hazards threatening visitor through the handheld terminal, and connecting the collected data and the spatial analysis request to the GIS spatial analysis server through the Web server in real time, so as to realize the buffer analysis considering the gradient; based on the knowledge base of secure locations in scenic spots and internet of things equipment, such as rainfall-sensor and water depth sensors, the radius of hidden danger buffer and parameter information of warning level are calculated in real time, and the knowledge formed in the analysis process is saved. By comparing and analyzing the historical information of Location Safety Knowledge Base, the temporal and spatial variation rules of newly added hidden danger features are discovered to determine the optimal value of hidden danger parameters. Then, through the geographic information system network service software, the new hidden danger buffer element layer is sent to the handheld terminal in real time, so as to avoid the impact of unsafe tourist caused by the untimely updating of hidden danger information in scenic spots, and improve the efficiency of safe production in scenic spots.
Highlights
With the development and application of new technologies such as mobile communication, Internet of Things and cloud computing, the concepts of Smart Earth, Smart City and Smart Scenic Spot(Chen et al.,2012) have been born since 2008.The concept of intelligent scenic spot has added new connotation to the informationization construction of scenic spot(Shao et al.,2010)(Dang et al.,2011)
In view of the existing problems, this paper proposes a real-time collection and analysis method and system of potential location safety hazard information for intelligent scenic spots under the environment of the Internet of Things(Jia,2010).Considering the change of slope in scenic spots, and the hidden danger buffer zone of topographic slope is analyzed with the collected data of point hidden danger, line hidden danger and surface hidden danger
A real-time acquisition and analysis system for potential location safety hazard information of intelligent scenic spots based on Internet of Things provides a set of real-time data acquisition and analysis system based on spatial database and spatial analysis server, which significantly reduces the workload of data acquisition and collation in the later period, and improves the speed of updating potential location safety hazard information of scenic spots
Summary
With the development and application of new technologies such as mobile communication, Internet of Things and cloud computing, the concepts of Smart Earth, Smart City and Smart Scenic Spot(Chen et al.,2012) have been born since 2008.The concept of intelligent scenic spot has added new connotation to the informationization construction of scenic spot(Shao et al.,2010)(Dang et al.,2011). There are few studies on the safety supervision and intelligent early warning of "smart scenic spots".In recent years, only representative achievements have been reported: Wang Qiuju's framework research and Empirical Analysis on the early warning of tourist flow in scenic spots based on network attention(Wang et al.,2014); Youweibin's construction and application of the early warning system of ecological security in the world's dual heritage sites(You et al.,2014).This shows that the domestic research on intelligent early warning of scenic spots is still a weak link, and there is still much room for improvement on the basis of existing research results.Safety is the basis of tourism development It is the guarantee for the smooth development of tourism activities, and the prerequisite for tourism development (Hua et al.,2009).The safety of tourists is very important for scenic spots.The natural scenery, which is emphasized by the words "strange" and "dangerous", often hides many hidden dangers of nature and man-made that threaten tourists.With the vigorous development of the intelligent tourism industry and the increasing number of scenic spots, the security problems of scenic spots are increasing day by day.Many scenic spots have complex topography and landforms, and there are many hidden dangerous and threatening areas with point, line and surface shapes, which are randomly distributed in the scenic area, which poses a great threat to the location safety of tourists in scenic spots.The influence range of hidden dangers in scenic spots is different according to the types of hidden dangers, and it changes with the month or precipitation. The real-time and spatial analysis technology of GIS is used to plot the potential hidden danger threat range in scenic spots.It can collect and analyze the existing hidden danger data in real-time space to meet the requirement of real-time updating and storage of intelligent scenic spots, and solve the key problems of inaccurate updating of hidden danger information and inaccurate location security information of tourists in scenic spots for early warning of hidden danger
