Abstract

The invention discloses a wireless torque sensor, which belongs to the field of sensors. The invention aims to solve the problem of low data transmission accuracy of the torque sensor in the prior art. The present invention comprises a hollow cylindrical casing, two metal rings are arranged on the outside of the cylindrical casing, the central axis of the metal ring is collinear with the central axis of the cylindrical casing, and several metal rings are installed on the two metal rings. The infrared diodes arranged in the circumferential direction of the metal rings, the two pins of the infrared diodes are respectively connected to the two metal rings; the invention solves the transmission problem caused by the same frequency wave or carrier bounce in the wireless transmission process. Inaccurate question.

Description

technical field [0001] The invention relates to the field of sensors, in particular to a wireless torque sensor. Background technique [0002] Torque is the most frequently involved parameter in rotating power systems, and there are various measurement methods, but no matter which method is used, how to transmit the measured torque value to the receiving device is a key factor affecting the measurement accuracy. [0003] Data transmission is mainly divided into wired transmission and wireless transmission. [0004] Wired transmission relies on the conductive slip ring to transmit the strain signal detected on the rotating body from the rotating part to the stationary part, but the conductive slip ring must be in frictional contact with the rotating body. Reliable signal fluctuations can easily lead to large measurement errors or even measurement failures. The higher the rotating speed of the rotating body, the more serious the wear and heat will be, and the life of the cond...
