Other AbstractThe invention relates to the industrial wireless network technology, in particular a low-overhead time synchronization method based on receivers under a star network. By sufficiently considering the application feature of an automatic star wireless network, the time synchronization method provided by the invention comprises the following steps: using a clock source device in the star network as one of receivers by using synchronized thought between the receivers based on IEEE STD 802.11-2007 standard and TDMA mechanism, comparing a receiving time value of the clock source device with that of a slave clock device so that the slave clock device can obtain an accurate time deviation value. Through the adoption of the method disclosed by the invention, the influence from transmission delay to timestamp data is eliminated, the target of precise time synchronization in the premise of high efficiency and low-overhead is realized.
