The invention discloses an electricity approach alarming method and device. The method comprises that the electric field intensity at the boundary of the maximal safety distance of an electrified body to be measured is set as the threshold of the electric field intensity in advance; electric field signal of different parts of the human body are received, and the electric field intensities of the different parts of the human body are measured; electric field intensities of the different parts of the human body are corrected, and whether the corrected electrify field intensities are greater than the threshold of the electric field intensity is determined; and if the corrected electrify field intensities are greater than the threshold of the electric field intensity, alarm is raised against exceeding of the safety distance limit. According to the electricity approach alarming method, the electric field is corrected by setting the weight, and influence of human body induction and electric field sensors on the precision of the electric field measurement is eliminated; the different weights are set to measure the electric field intensities of the different parts of the human body and the distance to the electrified body, so that the field intensity and safe distance are measured at the same time; and functions of portable equipment are integrated, load of maintenance staff can be alleviated in the live-line work process, and the working efficiency is improved.
