The invention relates to a high voltage transmission tower patrol system based on a GNSS (global navigation satellite system) and a two-dimension code, belonging to the field of the equipment maintenance. The high voltage transmission power patrol system comprises a tower two-dimension code nameplate which is arranged on a high voltage transmission tower, a patrol handheld terminal carried by the patrol personnel, a high voltage transmission tower data center which is arranged in a control center or a management center and a user terminal; an integrated intelligent patrol and information management system is realized on the basis of multimode GNSS point positioning, precise point positioning of GNSS/SBAS (satellite-based augmentation system), two-dimension code, GIS (geographic information system) and mobile communication network technology, a precise patrol position is provided by virtue of GNSS, the traditional patrol point is substituted by the two-dimension code, a wireless data transmission link is provided by the mobile communication network, the real-time dynamic information multimedia management system is realized by virtue of the GIS system, a more convenient, rapid, efficient and practical information management means is provided, and the high voltage transmission tower patrol system is an ideal high voltage transmission tower patrol and information management system.
