摘要: 本发明涉及一种基于4-20mA回路取电的802.15.4e无线设备低功耗组网方法,包括以下步骤:无线设备回路取电;构建面向超低能耗应用的无线网络;无线设备实现基于上述无线网络的单向时间同步;基于上述时间同步的基础上完成邻居发现;无线设备同无线网络交互;上述过程随着储能监测模块监测电量的结果进行暂停。本发明通过不停地切换信道来检测报文实现快速节能的单向时间同步,在时间同步的基础上通过监听普通报文代替传统的监听信标帧,改进邻居发现的监听次序,仅在信标帧可能出现的时隙打开监听,其余时间休眠,既节省了信道搜索的时间,又降低了邻居发现所产生的能耗,进而降低整个网络组建的时间和能耗。
英文摘要: The invention relates to a 4-20mA circuit electricity taking-based low-power-consumption networking method for 802.15.4e wireless equipment. The method comprises the following steps: performing circuit electricity taking on wireless equipment; establishing an ultralow-energy-consumption application-oriented wireless network; realizing one-way time synchronization based on the wireless network through the wireless equipment; finishing neighbor discovery on the basis of the time synchronization; interacting the wireless equipment with the wireless network; pausing the process along with the electric quantity measurement result of an energy storage monitoring module. The messages are detected by continuously switching channels so as to realize rapid and energy-saving one-way time synchronization, the traditional monitored beacon frame is replaced by monitoring common messages on the basis of time synchronization, a monitoring order of neighbor discovery is improved, the monitoring is started at the time slot in which a beacon frame possibly occurs only, the beacon frame is in a sleep state in the rest time, the channel searching time is saved, the energy consumption generated by the neighbor discovery is reduced, and the time and the energy consumption of establishing the whole network are further reduced.
