An Innovative Time Synchronization Algorithm for Wireless HART Networks

摘要

WirelessHART is widely used in the field of industrial process control. The communication between the devices is performed using Time Division Multiple Access (TDMA) with time slots of 10ms. In addition, a series of actions must be completed in the slot unit of 10 ms, including the data reception, transmission and acknowledge, etc. Time synchronization is the most important premise to ensure the communication secure, reliable and conflict-free.
