Design Of Smart Home Security System Based On 4G Network

With the help of wireless communication,sensors and embedded technology,smart home security system realizes real-time monitoring of indoor environment,mainly in order to prevent illegal intrusion,which can provide a strong basis for solving the incident.Firstly,this topic introduces the related wireless communication technology,combines with the characteristics of smart home security system,chooses ZigBee network as the networking technology,and compares three kinds of common ZigBee network topology structure,finally chooses star network topology structure as the system of this topic.The network topology.The selected ZigBee network technology has the advantages of low cost and low power consumption.It can detect and repair the faults accurately and quickly.It includes the functions of collecting,detecting data,processing information by transmitter,detecting and controlling environment.This topic constructs a smart home security system based on ZigBee technology.With the help of microprocessors,sensors and ZigBee RF chips,we can set up environmental parameters together.The environmental parameters need to be monitored include smoke concentration,temperature and humidity,etc.To realize online monitoring,and help with 4G technology.Users can realize remote monitoring and timely find various situations in the house and make timely response.Finally,we can test the main functions and security of smart home security system.After testing,it is found that the system can collect all kinds of data on the spot,give an accurate alarm in time after the occurrence of events that need to be alarmed,and use the mobile phone to view the remote situation,receive the relevant data,so that users can realize remote operation very conveniently.The system is stable in the process of operation,can achieve the expected design goals,and can meet the security needs of ordinary families.Figure14;Table6;Reference42...
