| After entering the new century,the tendency of the new technology application,which is "public security system" mixed with the "wireless Internet",has emerged.Not only the mobile phones but also the cameras and other new formats of data collection and analysis can be supported by the new technology.In the context of the emergence of the new application features,since the domestic public security organs have been using the old platform system all the time,which has caused a variety of incommensurate "symptoms",we need to modify and upgrade the system from different angles and levels.In a variety of alternative technology solutions,cloud computing is typical.It is the technology base of modern public security platform.The clouds closed storage,the parallel distributed cost-effective computing and the load balancing and dynamic allocations are the three basic components of the "cloud computing." Ordinary users can get computing performance that normally only supercomputer can achieve and the experience only high-speed computing and mass data can bring via a huge heterogeneous grid which is constituted by all kinds of low configuration terminals.The above form of service is a combination of on-demand allocation,dynamic solver and high user experience.Combined with the feature of the modern police system,such as large volume of data and high proportion of multimedia data type,this paper focuses on the application of mobile police cloud data transmission and management.The main research goal is the data storage management and data transmission bandwidth management issues of the mobile police cloud computing platform.In this paper,the access performance short defects of the mature technology namenode caused by non-multi-nodes are analyzed,and a new solution and corresponding realization method is designed from the perspective of data storage management.The main technology is:repiacing the single node processing technology of the traditional technology with heterogeneous non-unitary independent node cluster to achieve high-performance data,high reliability and storage.In the test of the MongoDB distributed file system,with the further widening and extension of the name scope,the association of node and the end user won't result in the NameNode inefficient cross-overlap.In order to verify the effectiveness of the new scheme,in the experimental environment,we conducted a full coverage test of the reconstructed new scheme,especially for large numbers of users parallel and high data read and write operations.Based on the application of the new program,the reaction time between two parallel service requests on the public security system platform is significantly reduced.Secondly,after the problem of single-node performance short-board,the thesis deeply analyzes the bandwidth of data transmission in wireless network,and puts forward the corresponding optimized solution.The rapid development of mobile applications will inevitably lead to low data transfer rate caused by the wireless network technology and the corresponding infrastructure,lengthy application service response cycle and other basic problems that will seriously affect the perception of the customer.In the existing related technology research,asynchronous JavaScript and XML technology,AJAX and lightweight data exchange format JSON combination can provide a technical solution for a large number of users to synchronize the request operation and for the system to fasten the service request response time.With the massive data on the new data transmission and communication portfolio,we carried out the targeted performance test on public security system platform.The result shows the obvious advantages on its parallel processing and transmission speed,which is extremely significant in practice when further improving the promotion of mobile public security platform.Finally,this paper discusses the two major technical breakthroughs in technology,prospects for practice,how to apply the final optimization scheme described in the text to the actual system,reflecting the value of its use. |
