Pedaling work computing method, system and intelligent pedals

Abstract

The invention provides a pedaling work computing method, a computing system and intelligent pedals. By virtue of a computing system, work done by a user who pedals a bicycle device is computed, wherein the bicycle device comprises the intelligent pedals which are arranged at the ends, relative to a fluted disc, of cranks and orientation sensors which are used for detecting rotating angles of the cranks. According to the method, pedaling force of the user exerting on the intelligent pedals is detected by virtue of pressure sensors on the intelligent pedals, and the rotating angles of the crankswhen the intelligent pedals are pedaled by the user are detected by virtue of the orientation sensors, so that work done by the user on the intelligent pedals is computed in accordance with the pedaling force which is detected at various time points within a force application time interval of the user and the rotating angles of the cranks. With the application of the technical solution, the workdone by the user who pedals the pedals of the bicycle can be precisely computed.

Description

technical field [0001] The present invention relates to a work calculation method and device, and in particular to a stepping work calculation method, system and intelligent pedal. Background technique [0002] Today, with the increasing popularity of sports, jogging, swimming and cycling are all very popular sports. When users ride a bicycle, they want to know how many calories they burn during the ride. At present, the products on the market use torque detectors to measure the work. It uses the torque value between the big chainring and the crank of the bicycle to integrate the angle, and the data of the work done by the crank on the big chain can be obtained, and used for conversion. calories consumed by the patient. [0003] Figure 1A to Figure 1C It is a relationship diagram between the force exerted by the existing user on the pedal of the bicycle and the rotation angle of the crank. Wherein, the direction in which the user steps on the bicycle pedal will change wi...

AI Technical Summary

Problems solved by technology

Under all the other states, the user must calculate the component force in the direction perpendicular to the crank 14 (as Figure 1B The component force F1 shown, Figure 1C The component force F2 shown), and the component force in the direction parallel to the crank 14 is lost as negative work

It can be seen that the above products can only calculate the work done by the bicycle, but this value will be smaller than the actual work done by the user, resulting in inaccurate calorie conversion
