In order to further improve the Internet of Things technology and ensure the ability and effect of the on-line monitoring system for electric energy metering. A parameter monitoring method of electric energy metering system based on Internet of Things technology is proposed. In this paper, the necessity and composition of the transmission line online monitoring system based on the Internet of Things technology are summarized. The sensing layer carries out real-time data exchange by using wireless communication interfaces and controlled devices, or supervises the components of intelligent sensors in a consistent way, and collects the information effectively, and classifies the real-time data into the controller. The network layer communication equipment is used to accurately transmit the collected information to the electric power network system, and it provides further reference for the management of various equipment scheduling. By using different information transmission methods, the unified information can transmit the perceived data to the circuit system, and the data can be classified and processed in a unified way. And all the effective information is collected in the controller for real-time data forwarding; The most important function of the application layer is to further process the information from the network layer, and at the same time, store it in a unified code, and then judge whether there are some faults in the line according to the information. At the same time, the problems existing in the running circuit are concretely speculated by comparing the values of normal operation and variables. With the intelligent development of on-line monitoring system for transmission lines, we need to further expand various technologies such as state sensors, and further establish and improve the intelligent monitoring model for transmission and transformation equipment.
