METHOD OF MONITORING WORKER LOCATION DURING OVERHEAD TRANSMISSION LINE REPAIR AND MAINTENANCE OPERATIONS, AND DEVICE

Disclosed are a method of monitoring worker location during overhead transmission line repair and maintenance operations, and a device. The method comprises: writing geographic coordinate information of an overhead power transmission circuit into a comprehensive process risk management and control main station system for electric power-related operations, and writing a worker location monitoring algorithm into the comprehensive process risk management and control main station system for electric power-related operations; reading geodetic coordinates of a repair and maintenance operation site, and reading geodetic coordinates of a worker being monitored; solving a distance therebetween on the basis of an algorithm approximating an arc length of an ellipsoid with a chord length; determining whether the distance exceeds an outside-of-monitoring threshold; if not, constructing a planar coordinate system of an activity area, and solving for the activity area on the basis of a vector triangle-based area algorithm;
