Design And Implementation Of Home Intelligent Security System

With the rapid development of social economy and the continuous improvement of science and technology,the traditional living environment has gradually exposed many security problems.Due to the rapid growth of urban floating population and the frequent occurrence of burglary cases,the traditional security measures can not meet people's needs.In order to protect the community and family security,a flexible and reliable security system is in urgent need.Therefore,the study of intelligent security system has a very important significance and value.Aiming at the disadvantages of traditional intelligent security system,such as difficulty of wiring,serious dependence on PC,high cost of development and so on,a scheme of home intelligent security system based on embedded technology and Wifi+NRF905 as its internal communication protocol is proposed in this paper,in order to solve the remote control of home Appliances and home security issues.The specific work is as follows.First of all,by analyzing the Internet of things and other related technologies,the overall scheme of home intelligent security system is designed.The scheme is based on ARM11 as the core control chip,through the mobile network and wireless transceiver module,the communication between the client and ARM and ARM and the terminal node is achieved.Terminal nodes include intelligent monitoring system,indoor lighting and temperature acquisition.Secondly,the main modules of the system are selected and the circuit is designed.S3C6410 is determined as the main control chip,MSP430 is node controller,as well as DS18B20 and other hardware devices.In addition,the hardware circuit of the ARM minimum system,video surveillance,infrared radiation and lighting equipment is designed.In the software,a mobile phone App of remote control and viewing the home node equipment is designed based on Android system.At the end of ARM,the software platform is set up,including the transplantation of bootloader,Linux kernel and file system.According to the specific needs,server and database environment is built on the platform,a number of interface scripting is compiled.In the MSP430 side,the driver and Application program of the node is compiled.Finally,the software and hardware test platform is built through the above design.During the testing process,the mobile phone App can receive the information effectively,and can send the control command successfully.The running effect of the system can meet the design requirements basically.Through the design of the hardware and software of the home intelligent security system,the system test platform is built in this paper.The operation results show that the mobile phone App can obtain real-time video monitoring information through infrared alARM,realizing off-on control of lighting system and the acquisition of indoor temperature information.The test results are feasible and practical.It has certain reference value in the intelligent security system industry.
