Research On System Development And Network Deployment For Road Manhole Cover Information Collection

With the rapid development of cities and the acceleration of infrastructure construction,there are more and more underground pipeline lines in urban roads,and the coverage is expanding.As the monitoring entrance of pipeline network,the well cover is also increasing.In recent years,due to the increasing number of road covers,uneven distribution and wider coverage,there are difficulties in management,leading to frequent accidents,affecting the safety of people and vehicles,and bring adverse effects.Considering management and safety,the establishment of online monitoring system is an effective means to solve this problem.The important component of the monitoring system is the information collection.The establishment of a perfect,reliable and effective information collection system helps to reduce the potential safety hazards.Because of the strong ability of information acquisition and processing in wireless sensor networks,it is a com?on way to use wireless sensor networks to achieve information acquisition.Node deployment is related to the accuracy,completeness and timeliness of information acquisition,and it is the first problem to be considered in network deployment.Reasonable deployment mode can ensure network coverage and connectivity,improve work efficiency and optimize network resources.Therefore,it is necessary to focus on the deployment of nodes in combination with on-line monitoring.Firstly,the thesis introduces the research background and significance,related technology and the development status at home and abroad;secondly,on the basis of explaining the overall structure of the online monitoring system,it designs the data collection,reception and distribution system,secondly,it focus on the optimization problem of network deployment,and uses optimization algorithm to seek reasonable planning.Deployment.The main work and innovation of the thesis are as follows:1.The design and development of data receiving and publishing of online monitoring system,and the management and analysis of monitoring data based on the system,to provide practical data support for subsequent node deployment.2.According to the characteristics of information acquisition technology and wireless sensor network technology,the information acquisition node model and network model are established.Aiming at the communication performance and coverage performance of the network,a set of performance evaluation index system for node deployment problem is proposed,and a mathematical model for node deployment problem is established Particle swarm optimization(PSO)is used to solve the deployment optimization problem.3.Aiming at the disadvantage that particle swarm optimization is easy to fall into local optimum,a strategy is proposed to improve particle swarm optimization.The basic particle swarm optimization(PSO)and improved particle swarm optimization(IPSO)are used to solve the node deployment optimization problem.4.The simulation deployment experiment were performed,taking the roads as example.The basic PSO,basic genetic algorithm and improved particle swarm optimization(IPSO)are used to optimize the layout of network nodes.Comparing the results optimized by the three algorithms,the effectiveness and feasibility of the PSO in optimizing wireless sensor deployment was verified.Figures:70,Tables:14,References:66.
