Out-of-limit detection method and device for safe region of transformer substation

Abstract

The invention discloses an out-of-limit detection method and device for the safe region of a transformer substation. The method comprises the following steps that: taking any point in the unsafe area of the transformer substation as an original point, and establishing a two-dimensional coordinate system; obtaining the vertex latitude and longitude coordinates of the unsafe area shape of the transformer substation, and generating corresponding vertex plane coordinates; and establishing the linear boundary equations of two adjacent vertex plane coordinates in sequence; obtaining the latitude and longitude coordinates of the current position of operating personnel, and generating the corresponding plane coordinate of the current position of the operating personnel; establishing a linear detection equation for the plane coordinate of the current position of the operating personnel and the plane coordinate of any one detection point in the two-dimensional coordinate system; according to a linear cross calculation formula, obtaining a plurality of intersection plane coordinates; according to an accumulating calculation formula, obtaining an accumulated value; and judging whether the accumulated value is an odd number or not. By use of the method and the device provided by the embodiment of the invention, the problem that an existing unsafe area can not be accurately monitored can be effectively solved.

Description

technical field [0001] The present application relates to the technical field of substation safety monitoring, and in particular to a method and device for detecting limit violation of a substation safety area. Background technique [0002] As the country's requirements for power supply reliability are getting higher and higher, the daily inspection of substations is becoming more and more important. As a special production unit, the substation has a large number of highly charged equipment. On-site workers who are close to live equipment or accidentally touch live equipment may cause irreparable damage to personal and equipment. In order to ensure the personal safety of on-site workers and prevent safety production accidents caused by personal negligence and violation of safety regulations, the power industry has formulated a series of safety regulations, operating specifications and precautionary measures to guide on-site operations. [0003] Since the warning measures ar...
