Abstract
Wireless sensor network has offered possibility for distributed information acquisition of mining equipment. Since the device-related information of different nodes of one device can be integrated, a more accurate decision-making and estimation of the mine equipment operating status can be obtained through study of internal coupling of signals and subsequent analysis of operating conditions of entire equipment. Time synchronization algorithm is a prerequisite for whether the follow-up analysis is correct or not. The RBS (Reference Broadcast Synchronization) time synchronization algorithm suitable for mining equipment vibration perception is analyzed in this paper. In order to solve problems such as big energy consumption and long synchronization convergence time in applications, the improved IRBS (Improved Reference Broadcast Synchronization) time synchronization algorithm is proposed. Finally, the designed network model has been used for comparison on the energy consumption and convergence time of IRBS and RBS. The simulation result shows that energy consumption and synchronization convergence time during synchronization can be significantly reduced with the improved algorithm. The improved algorithm has been successfully applied to equipment monitoring in the Huoer Xinhe Coal Mine of Shanxi Coal Imp&Exp. Group Co., Ltd.
