Research And Application Of Fire Information System In Big Data Environmation

With the continuous improvement of the information system,the fire protection network is also developing rapidly.Computer management is an indispensable part of the fire service business.Computer management has a significant role in improving the fire service and is also great value to the safety of local communities.In order to realize fire information,there are many fire service activities in various places,therefore,we accumulated a large amount of fire fighting experience.However,there are also various problems in the fire service,such as the different time of fire construction and the lack of unified scientific guidance for the fire service,which makes the fire departments in different places unable to effectively use fire information.With the advent of the era of big data,fire services face new challenges.In the big data environment,because of the huge amount of data and the complex data types,the traditional fire information system can be unable to adapt to the development of the era.This paper focuses on the mainstream data platform Hadoop.In order to adapt to the development of the era of big data,we study data backup and access control model,and improve on the hadoop platform.Firstly,this paper introduces the fire information system,and it describes the development of fire information system and the basic model of fire management system.Secondly,this paper introduces the Hadoop platform,and it describes the storage mechanism and replica placement strategy of HDFS(Hadoop Distributed File System).Because of this,we propose a new replica placement strategy which introduces "resource weight value" and realizes dynamic resource weight setting.This new replica placement strategy improves the utilization of cluster resources.Then,we propose a new access control model on the basis of previous research on access control which introduces "user behavior analysis" and realizes the dynamic setting of user access rights,and improves the security performance of information in fire information system.Finally,we validate the two improvements and give the general design of big data fire information system which uses Hadoop platform.Our aim is to improve the fire information system,which is under the information system.
