Design And Implementmtation Of Intelligent Security Based On WIFI-2.4G Technology

In 2015,Premier Li Keqiang proposed the "Internet+" action plan for the first time in the government work report at the Third Session of the Twelfth National People's Congress,and emphasized the need to develop "Smart City".With the rapid development of the economy,the acceleration of the urbanization and the enhancement of the awareness of national security have continued to increase,and people are paying more and more attention to the safety issues in the living environment.The intelligent security system can meet people's security needs to a certain extent by discovering and eliminating security risks in time,notifying the user of abnormal information and receiving remote control of the user.Therefore,the smart security system has become a very important part of a smart city.It is of great practical value to build an "Internet+Intelligent Security System" and build a new security ecosystem.Based on the in-depth study of related technologies at home and abroad,this paper designs and implements a smart home security system based on WIFI-2.4G wireless technology.The system adds a local intelligent linkage module on the basis of traditional intelligent security devices,enabling the sensors and control devices in the system to be linked in real time,and handling security risks under conditions that cannot be communicated with the outside world due to special circumstances such as disconnection or power failure.Security devices can autonomously handle security threats that occur in their environment,thereby improving the real-time security measures.This system uses 2.4G wireless transmission technology as the local network communication scheme,and designed a set of communication encryption and decryption algorithms to ensure the safety of local communications.The smart home security system designed in this article can discover and manage sensors and control devices in the local network in a self-learning manner.Through sensors,various security-related parameters in the environment are collected and analyzed.When security risks are discovered,they can be handled in accordance with the linkage.The plan calls control equipment to eliminate safety hazards in a timely and effective manner.At the same time,the environmental data is transmitted to the remote server,the server is responsible for analyzing and processing the situation that cannot be handled by the local security equipment,and the corresponding control instruction is sent back to the local security equipment;in addition,the server is also responsible for pushing the abnormal information to the user in time through the mobile communication network.The user can also view the operation status of the security device in real time through the mobile phone application and configure related functions and parameters of the security device.The test results show that the system operation is simple and flexible,and the response to safety hazards is timely and effective.The system realizes the local real-time monitoring of the environment and remotes network management functions,improves the level of security protection of modern families,and has a wide range of practical value.
