Description

technical field [0001] The invention relates to the field of wireless energy transmission, in particular to a wireless energy transmission method and device for a train sensor network. Background technique [0002] With the rapid development of train technology, higher requirements are put forward for the monitoring of different positions and parts of the train. The wired sensor network cannot meet the monitoring requirements of difficult-to-wire areas on the train. The train wireless sensor network based on wireless energy transmission technology does not need to replace the battery or wired charging of the network nodes, which can save labor costs and installation complexity, so that the wireless sensor network can work efficiently and stably. The current wireless energy transfer technologies mainly include electromagnetic induction, magnetic resonance and electric field coupling. However, the energy transmission distance of these technical solutions is relatively limited...
