    摘要: The present invention relates to a low power consumption networking method of an 802.15.4e wireless device that takes power used on a 4-20 mA 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.

    摘要: The present invention provides an AP handover method based on double wireless network interface cards. A mobile terminal actively scans the signal strength of an AP, compares the scanned signal strength with the signal strength of a currently accessed AP, and if the signal strength is greater than the signal strength of the current AP, starts handover; otherwise, continuously scans till the handover succeeds. To reduce the handover delay and in accordance with the characteristic that the moving paths are basically fixed in industrial application scenarios, the present invention provides a pre-learning mechanism, that is, before formal application, information such as the location of the AP and the handover sequence in the application scenario is learned and stored in a terminal node, so that specific scanning and handover can be implemented in formal application. The present invention solves the problem of rapid AP handover in the industrial mobile network scenario, the double wireless network interface cards are used to achieve handover without interruption, and the pre-learning mechanism is used in specific industrial application scenarios, so the scanning delay is further reduced.
