摘要: The present invention relates to a low power consumption networking method of an 802.15.4e wireless device that takes power based on a 4-20mA loop, which comprises the following steps: a wireless device taking power in a loop; constructing a wireless network that is oriented to an ultra-low power consumption application; the wireless device implementing unidirectional time synchronization based on the preceding wireless network; on a basis of preceding time synchronization, completing neighbor discovery; the wireless device interacting with the wireless network; and pausing a preceding procedure according to a power monitoring result of an energy storage monitoring module. The present invention detects messages through continuously switching channels to implement quick and energy-saving unidirectional time synchronization, replaces traditional listening on beacon frames with listening on common messages on a basis of time synchronization, improves a listening sequence for neighbor discovery, enables listening only at a time slot where the beacon frames may appear and sleeps at other time, not only saving channel search time, but also reducing energy consumption that is generated in neighbor discovery, and thus reducing time and energy consumption of entire network establishment.
