The invention relates to a double-flat-arm derrick torque monitoring device which comprises a rod body, suspension arms are symmetrically arranged on the left side and the right side of the rod body, a tackle is arranged on the suspension arms in a sliding mode, a crane scale, a laser range finder, a controller, a circular grating encoder and an NFC position recognizer are arranged on the tackle, and a gear on the circular grating encoder is matched with a rack on the suspension arm. The controller is in electric control connection with the laser range finder, the circular grating encoder and the NFC position recognizer, NFC position labels spaced by a first distance are arranged on the suspension arm, and the NFC position labels are located in the induction range of the NFC position recognizer. Compared with the prior art, the method has the advantages of real-time unbalanced torque difference display, over-limit alarm and the like.
