This invention provides a cooperative coverage method for distribution network information perception. The cooperative coverage method includes the following steps: construction of connected cooperative coverage sets, which can cover all target nodes with as few information perception nodes as possible, and maintain the connectivity of each cooperative coverage set with connected sets construction methods based on of hierarchical clustering; Cooperative coverage set scheduling, introducing the concept of energy ratio threshold, dividing the life cycle of the system into multiple time slices, calculating the energy ratio of perception device set in each time slice to realize the set scheduling. The invention realizes the efficient utilization of the energy of the perception device through the construction and scheduling of the connected coverage set in different time slices, and improves the use efficiency of the information perception network.

Cooperative coverage method of information perception for distributed network

A system for monitoring a power transmission line of a power grid, including a first comprehensive sensor () disposed at the intermediate position of a power transmission line between two towers including an altimeter, a first acceleration sensor, a temperature and humidity sensor and a rainfall sensor; a second comprehensive sensor () disposed at the cable connector of the power transmission line including a leakage current sensor, a tension sensor and a wind speed and direction sensor; and a second acceleration sensor () disposed at the intermediate position of the power transmission line between the cable connector of the power transmission line and the first comprehensive sensor (). A method for monitoring a power transmission line of a power grid, including a step of monitoring the sag condition, wind yaw angle, motion and position tracking, flutter conditions, breeze vibration level, fatigue life and icing situation of a power transmission line. The method and system for monitoring a power transmission line of a power grid effectively prevent and reduce incidents of the power transmission line of the power grid based on sensor multi-dimensional sensing technology combined with the advantages of wireless sensor network technology.
