The Desigh Of Intelligent Home System Based On Raspberry Pi

All kinds of household equipment in the traditional smart home system are independent and passive,and they take on all the functions of the family.From a systematic point of view,they are fragmented,disorganized,and not an organic,organized whole.The key difference between the traditional home and the smart home is that the realization of the various functions of the family has been transformed from decentralized and independent mechanical control into integrated and interoperable network management and control.The thesis proposes a design scheme of smart home system based on Raspberry Pi.This system integrates individual and different operating modes of home equipment.According to the people-oriented and the integration of individual needs,the independent passive open mode is transformed into the management and control of active intelligence,and the indoor and living environment can be controlled as much as possible.The system takes Raspberry Pi as the hardware platform and embeds the Raspbian operating system as the software development running environment.The design of smart home system consists of four parts: remote login module,communication access data module,database management module and terminal intermediate control module.The remote login module uses PHP technology,to respond to the dynamics of the browser client requests,data management and service functions.The communication access data module is coupled to some intelligent home devices,it uses shell script technology to filter and discern the data message file in the communication adapter,so as to solve the redundant data from the multiple subsystem.Use Mutt Mail Forwarding technology,then it feedbacks dangerous emergency information to remote client mailboxes.The user privilege system has established in the database management module.Different users of intelligent devices have different operating privileges,and the user also has a linkage operation function to satisfy the needs of individual user control.Terminal intermediate control module is control center,through the shared memory and semaphore control technology to solve a single instruction control multiple subsystem,through the machine learning to generate rule by using the database storage history operation records and ultimately to achieve intelligent management purposes.The main difficulty of design and research is how to break complex instructions or data,then realize linkage operation,and how to realize intelligent management of home,and leave manual constraint control,at the same time both energy saving,low cost,easy to expand and other characteristicsFinally,this thesis tests the functional modules of the smart home system.The obtained sensor entity data is tested by using the initialization rule information and the rule information after the update of the decision tree.The experiment shows that the intelligent home system based on Raspberry Pi is designed to meet the needs of home users,and the operation effect of each module meets the design requirements.At the same time,it proves that the single instruction multiple control and the use of data intelligent generation control rules are viable.It is of great importance to the intelligent application of smart home system.
