Abstract
The invention provides a time synchronization method of an electric power wireless sensor network based on a power transmission line. The time synchronization method comprises the following steps: each node in the electric power wireless sensor network detects an electric signal on the power transmission line and judges whether the electric signal passes the zero point; otherwise, the detection is continued, and if so, the zero point passing times of the electric signal are counted; and a sensor node works or sleeps with the zero point passing times as a standard time. The time synchronism of the nodes of the electric power wireless sensor network can be effectively guaranteed to ensure the data interaction of the entire network, moreover, the properties of the electric power wireless sensor network can be satisfied, and the service lives of the nodes of the electric power wireless sensor network are satisfied.
