Measurement apparatus and method for determining the magnetic field strength at a specific location using electronic maps

Abstract

The present invention relates to a measurement apparatus and method for determining the magnetic field strength at a designated location using electronic maps. The device consists of a processing unit, a loading unit, a directional marking unit, a conversion unit, a calculation unit, and a display unit. The measurement method involves loading the electronic map, setting the designated location and measurement range, identifying geographical features and dimensions, calculating the characteristic scores of the geographical features relative to the designated location, extracting triangular azimuth integrals and evaluation totals for different evaluation items, calculating the magnetic field strength indicator for the designated location according to the weight ratio, and finally displaying the result on the measuring device. This allows users to understand the magnetic field conditions at the designated location within the measurement range in real time, helping them choose suitable places to live.
