Device for measuring stay wire of tower based on radio frequency identification

The utility model provides a device for measuring a stay wire of a tower based on radio frequency identification. The device comprises a stay wire reel buried underground, an RFID electronic tag, a mobile reader and a portable computer, wherein the RFID electronic tag is arranged on the stay wire reel, and the mobile reader is connected with the portable computer. The mobile reader respectively transmits a radio frequency signal in at least three positions, and the portable computer calculates actual geographical coordinates of the central point of the stay wire reel according to the radio frequency signals transmitted by the mobile reader and received response signals. Due to good penetration of the RFID anti-metal electronic tag, survey personnel can determine the actual geographical coordinates of the central point of the stay wire reel conveniently, quickly and accurately through the reader and does not need to find a part, going out from the ground, of a stay wire rod manually. The device can be used in
