Abstract

The invention discloses a torsion acquisition system and a pedal sensor, and the torsion acquisition system comprises: a first full-bridge circuit which is configured to output a corresponding first strain voltage according to the resistance value of a first strain unit and the resistance value of a second strain unit; a second full-bridge circuit which is configured to output a corresponding second strain voltage according to the resistance value of the third strain unit and the resistance value of the fourth strain unit, wherein the first strain unit, the third strain unit, the second strain unit and the fourth strain unit are sequentially fixed to the pedal transmission shaft in the circumferential direction of the surface of the pedal transmission shaft; and a signal processing circuit which is configured to output the acquired data according to the first strain voltage and the second strain voltage and calculate torsion transmitted to a crank of the bicycle by the pedal transmission shaft according to the acquired data and a preset comparison program. According to the invention, the torsion transmitted from the pedal transmission shaft to the crank of the bicycle can be calculated more accurately, and high-precision seamless torsion acquisition is realized.

Description

technical field [0001] The application belongs to the technical field of bicycle electronic accessories, and in particular relates to a torque collection system and a pedal sensor. Background technique [0002] In recent years, cycling has become more and more popular with the public. In the past, only professional athletes used power meters, but now it has attracted more and more attention from amateur players. Moreover, the improvement of the power meter to ordinary fans will be even greater than that of professional players. Because the power meter measures the real-time output power rate of the rider, it can allow amateur athletes to better distribute their physical strength. [0003] At present, the power meters on the market generally include chainring type power meters, hub type power meters, crank type power meters, pedal type power meters, etc. Among them, the pedal type power meters are more favored by business enthusiasts because of their convenient installation....
