发明名称 Synchronization of a Plurality of Devices in a Wireless Sensor Arrangement
摘要 Two or more wirelessly networked devices for control or data acquisition functions for real-time application are provided with a error corrected synchronization and data collection process. A single start device transmits a start message, followed by each stop device acknowledging that start message. If one or more stop devices fails to acknowledge the initial start message, one or more start messages are transmitted including an elapsed time since the initial start message. Each stop device receives the initial start message and any subsequent start messages, using the elapsed time in the start message to synchronize a local timer. Upon stop event detection, each stop device records its local timer value and subsequently transmits that value to a collection device or console.
