Research On Smart Grid On-line Monitoring Technique Based On Internet Of Things

With the increasing pressure of the global resources and environment and the rapid development of science and technology productivity,the demand for electricity in all walks of life is increasing,and the demand for power supply reliability is increasing gradually.Thus,the operation of the power grid is facing enormous pressure.This is undoubtedly a test of the security and stability of the power grid system.Because transmission lines are often distributed in complex and complex areas of the environment,the complex and changeable actual geographic environment will affect the normal operation of transmission lines to a certain extent,such as high wire temperature,voltage and current failure,wire tension and conductor icing,and so on.To find out the fault points and solve the corresponding problems.In this paper,based on the above problems,and according to the actual situation,a certain number of sensors with perceptual function are installed in a certain area.It is beneficial to discover problems in time,reduce the occurrence of major accidents,and play a good role in solving the problems mentioned above,and can reduce the workload of the staff.This paper mainly completes the design of the software and hardware circuit for the on-line detection of transmission lines.Through on-line detection of the transmission lines,it can master the running state of the transmission line in real time.It can detect the voltage,current,wire temperature in the transmission line,the tension of the wire and the icing of the wire,and the running letter of the transmission line.The interest is displayed on the upper computer interface,and it can grasp the information of the transmission line in time.While reducing the workload of the staff,it can also achieve the purpose of improving the efficiency.In order to verify and evaluate the effectiveness and advantages and disadvantages of the onlinemonitoring system based on the Internet of things technology,the routing protocol in the network layer in the three layer network structure of the Internet of things is studied.The AODV routing protocol in the network layer is optimized,and the work of the backup route is added on the basis of the original protocol.As a result,the main routing and backup routing can be switched adaptively to reduce the dependence on the main path.In the experiment,small,medium and large networks are selected for simulation.In the simulation process,the packet delivery rate,the end to end average delay,the normalized load and the route initiation frequency are selected respectively in the simulation process.The simulation results show that the improved protocol improves the success rate of packet reception,further reduces the delay,reduces the normalized load,and greatly reduces the number of route discovery.
