Time synchronization plays a key role in the wireless sensor networks (WSN).High precise time synchronization is all application foundation in distributed control systems. In order to realize united time, the united time service system or the time server must be established. Based on wireless sensor networks, information fusion automatically analyzes and monitors information under the certain criterion, in order to complete the necessary decision-making and assessment missions, obtain consistency interpretation and description of tested object and allow the system to obtain superior performance than its various components. Based on wireless sensor network building, time synchronization technology and fault-tolerance time synchronization strategy were studied and the error analyses are given, the time correct value algorithm and the analyses to the synchronization result are proposed.
