Abstract：Aiming at the problem that mechanical vibration wireless sensor networks rely on clock synchronization, beacon synchronization, communication between nodes synchronization and low accuracy, a path sensing synchronization trigger method in cluster network is proposed. Firstly, the dual-mode multiplexing method is used to design the node architecture, and the adjoint networking method is proposed to construct the network topology under the cluster network. Next, the path sensing time measurement method with the auxiliary device measurement as the core is proposed to the dependence on beacon and improve the synchronization trigger accuracy. Finally, the maximum time difference compensation and time first synchronous trigger measurement method are proposed to solve the problem time delay compensation and system instruction interruption. The experimental results show that the maximum error of path sensing synchronization trigger is between 50 and 60μs, and the minimum error is between 10 and 16μs.
