Description

technical field [0001] The invention relates to the field of indoor wireless charging, in particular to an indoor Internet of Things multi-target wireless charging system and a positioning and charging method thereof. Background technique [0002] With the continuous maturity and development of the Internet of Things technology, a large number of sensors and control nodes are built into a network through wireless technology, which plays an extremely important role in the monitoring and management of the system. Long-term energy supply for IoT nodes has been a bottleneck due to lack of means to recharge batteries. The existing solution is to reduce the power consumption of the node as much as possible and prolong the working life of the battery. However, this scheme imposes severe restrictions on the performance and functions of nodes, such as requiring nodes to be in a sleep state for a long time, and only work and communicate for a short time. Although this method effecti...

Problems solved by technology

Long-term energy supply of IoT nodes has been a bottleneck due to lack of means to recharge batteries

However, this technology also has the following problems: first, the light propagates in a straight line, how to accurately align the laser with the photocell, especially how to achieve charging during the movement of the node to be tested; The dead zone problem; Third, how to realize simultaneous charging of multiple charging nodes

These problems severely limit the development of indoor wireless charging technology, and also limit the application and development of the Internet of Things

Therefore, the indoor wireless power supply technology of nodes severely limits the development and application of the Internet of Things
