AI Technical Summary

Technical Problem

The magnetic field distribution of wireless charging stations varies greatly, and different groups of people have different tolerances to magnetic field strength. Existing technologies are unable to detect and warn pedestrians in real time to protect their health.

Method used

Design a safety magnetic field critical point detection device, including a base, a walking component, a stake, first and second detection components, and a control component. The device detects the magnetic field strength and controls its movement to the critical point, and uses a warning component to alert pedestrians.

Benefits of technology

It enables visualized and graded detection of the magnetic field distribution of wireless charging stations, effectively preventing pedestrians from entering harmful magnetic fields and protecting their health.

Abstract

This invention provides a safety magnetic field critical point detection device and a method for hierarchical detection of magnetic field distribution. The safety magnetic field critical point detection device includes a base, a pile, a first detection component, a second detection component, and a control component. A walking component is located at the bottom of the base. The pile is located on the upper side of the base and has a warning component. The first detection component is connected to the pile and is used to detect the field strength at the location of the pile. The second detection component is connected to the pile and is adapted to rotate around the pile to detect the field strength around the pile. The control component is electrically connected to the walking component, the first detection component, and the second detection component, and internally stores the critical point field strength. The control component is adapted to control the walking component to move the pile to the critical point field strength based on the field strength detected by the first and second detection components. The hierarchical detection method of magnetic field distribution, based on the above-mentioned safety magnetic field critical point detection device, can realize hierarchical visualization of magnetic field distribution.
