Mobile Client Of Building Automation System Based On Application Scenario Security Reasoning

With the continuous development of technology in the field of mobile interconnection,people have put forward more demands on intelligent building management,and the Building Management Automation System(BMAS)is developing in the direction of mobile and intensive.However,with the continuous expansion of the functions of the BMAS,the application scenarios of the system are more complex and diversified.Meanwhile,the mobile client itself has security risks such as operational randomness,easy to lose equipment and so on.Based on the above problems,this paper propose a building management automation system based on application scenario security reasoning.The establishment of application scenario security model needs to simulate and analyze the scenarios in the process of building management and control,and consider the factors of different user groups,scene conditions and operation processes.Combined with the algorithm of data threshold condition analysis,process control management,intelligentized allocation of authority and so on,it can effectively avoid the possible engineering security problems in different scenarios and ensure the stable operation of the building system.What's more,it establishes user behavior habit models through behavioral habitual algorithm to verify the rationality of user operation.With the increasing use of users,user behavior habit models are constantly updated to form a long-term mechanism for safety management.This paper selects the mobile client as the control terminal and select the Android client as the main development object.The Android client uses the fragment component to design a simple and friendly client operation interface.Through the data simulation and the real machine test,the application scenario security reasoning model can identify the different application scenarios well,effectively avoid the scene security problems,identify the user behavior habits,and provide better security for the system security.It can basically meet the practical needs of the engineering application.This system provides a train of thought for effectively solving the security problems of the building management control system which is in the process of mobility.On the premise of ensuring the mobility and functional diversity of the system,it gives full consideration to the different security problems of the application scenario and put forward solutions.The system has good application value.
