Research And Implementation Of Data Security Monitoring System For Household Electricity In The Environment Based On Internet Of Things

Electric power information monitoring is a basic and important step in the construction of ubiquitous power Internet of things.The household electricity data security monitoring system is a specific application form of ubiquitous power Internet of things at residential side of electricity information monitoring.Moreover,it is an important measure for electric power sector constructing more efficient,safer and more intelligent power system.Therefore,this paper studies the security monitoring system of household electricity data in the Internet of things,which ensuring the user monitoring the specific household electricity situation under the condition of safe transmission of household electricity data.The main research contents of this paper are as follows:? The functional requirements and key technologies of household electricity data security monitoring system were studied.Considering the research status of Internet of things and family consumption monitoring system,in terms of neglected safety power of the electricity data,and user monitoring large time delay problem,we determine the functional requirements of the system and key to it,and build a system architecture based on the Internet of four layer model.? The core hardware of the system was designed and implemented.Combined with the key technologies required by the system,the hardware structure block diagram of the sensing layer is designed.By comparing the component parameters in power consumption data collection data module and time management module,the core hardware of the system,such as the power data acquisition terminal in the sensing layer,the routing node and the protocol conversion gateway are realized.? A safe transmission scheme for household electricity data was proposed.We propose a RFID legal authentication scheme which completing the authentication of the incoming request node by RFID hardware and pull encryption algorithm to avoid Zig Bee wireless transmission vulnerable to illegal nodes.A hybrid encryption scheme based on improved digital signature is proposed to construct a second secure transmission line and to solve the problem that pseudo-ciphertext-signature pair can also pass the signature.By analyzing and testing the ability of these two schemes to resist security attacks,it is proved that both schemes can improve the security of electricity data transmission.? The edge computing platform was designed.The edge computing technology is integrated into the protocol transformation gateway and the edge computing platform is constructed?By adopting the edge cloud collaborative work mode and designing the functional architecture and tasks of the edge computing platform,the power data is transferred to the cloud server platform after local processing,and the risk of privacy data leakage in the cloud is reduced.Experimental results show that the edge computing platform has faster service response speed.? The system website and mobile terminal APP were designed and implemented.Combined with the system function requirements,the user can monitor the household electricity situation of each region and each time period personally and remote control of power data acquisition terminal on and off state in the condition of the appropriate development environment and the system website and APP function design.Tested by experiment,the system website and mobile terminal APP can meet the functional requirements of the system by tests.
