Research And Application Of Health Monitoring System Of Xi’an Olympic Sports Center Stadium Based On WSN

With the growth of national economy and the progress of science and technology,China’s construction industry has developed rapidly.At present,China has become the country with the largest number of skyscrapers in the world.All kinds of super high and long-span buildings are emerging.These buildings are not only huge in volume,unique in building shape,but also complex in structure system.In particular,the large-scale stadiums and gymnasiums that are being built all over the country are not only the sports center of the local people,but also the new landmark of the city.The superstructure(canopy)of these large-scale stadiums mostly adopts the form of long-span space steel structure,which has the characteristics of light weight,excellent bearing capacity and seismic performance.However,due to the complexity of long-span space structure,the stress range of main structural members changes greatly,which is highly sensitive to the use environment temperature and humidity,and the corrosion factors in the environment have a great impact on the long-term safety of the structure As a densely populated public building,the safety of use is the primary task of venue management.In order to ensure the safety of personnel and use,it is of great practical significance to grasp the safety status of buildings in real time and carry out health monitoring of buildings.Taking Xi’an Olympic Sports Center Stadium as the research object,this paper monitors the safety performance of the building structure in the whole process of building construction and use.Based on wireless sensor network,a wireless monitoring system based on ZigBee technology and GPRS technology is established,which realizes the realtime collection,wireless remote transmission and storage of monitoring data,and develops a long-distance B/S architecture The effective health monitoring information management system can provide reliable data for users to grasp the health status of buildings in real time.The main research contents are as follows:(1)Based on the analysis of health monitoring technology at home and abroad,using wireless sensor technology and wireless communication technology to design the overall framework of the stadium health monitoring system of the Olympic Sports Center,then according to the determined monitoring parameters and data transmission scheme,the wireless remote health monitoring data collection system is designed,and the hardware design,software design of the wireless monitoring node are completed Network debugging,so as to realize the real-time monitoring and remote transmission of the underlying data.(2)Aiming at the problem of sensor network coverage,the optimization model of wireless sensor network coverage is established,and the model is simulated by swarm intelligence algorithm.The results show that the artificial fish swarm algorithm is superior to the social particle swarm algorithm in optimizing the coverage of wireless sensor network,which improves the coverage of sensor network,reduces the overlap of monitoring area coverage and blind area phenomenon,so as to realize the effective allocation of network resources and extend the service life of wireless sensor network.(3)Establish health monitoring database based on SQL server,realize the storage and management of monitoring data,develop health monitoring information management platform based on B/S architecture,and complete the visual display of monitoring data.
