Resistance torque real-time adjusting method, system and equipment and readable storage medium

Abstract

The invention provides a resistance torque real-time adjusting method. The method comprises a test link and an application link. In the test link, the control module obtains, establishes and stores a corresponding relation table of the rotating speed, the current and the torque; in the application link, the control module receives a target torque instruction, and the target torque instruction comprises a target resistance torque; monitoring the real-time rotating speed of the resistance wheel; according to the corresponding relation table, the target torque instruction and the real-time rotating speed, a regulation and control current is calculated; regulation and control current is input into the electromagnet, and real-time adjustment of resistance torque is achieved. And when the rotating speed of the resistance wheel changes, the control module can recalculate the regulation and control current to keep the target resistance torque constant. Therefore, the resistance torque can be accurately adjusted in real time, the method is suitable for various electromagnetic control resistance wheel products, each electromagnetic control resistance wheel product has an independent product characteristic table (a corresponding relation table of rotating speed, current and torque), and the resistance torque does not need to be adjusted by adopting average data of a plurality of electromagnetic control resistance wheel products.

Description

technical field [0001] The present invention relates to the technical field of electromagnetically controlled resistance wheels, in particular to a method, system, device and readable storage medium for real-time adjustment of resistance torque for electromagnetically controlled resistance wheels. Background technique [0002] The electromagnetic control resistance wheel is to pass current to both ends of the electromagnet. When the resistance wheel rotates, the magnetic field lines are cut, and an eddy current is formed on the surface of the resistance wheel. That is, drag, which creates a drag torque on the outer ring of the wheel. Direct current or current of different waveforms (such as square wave, sine wave, etc.) is applied to both ends of the electromagnet to maintain a certain voltage, or maintain a certain current, so that the electromagnet can generate continuous resistance torque to the resistance wheel. [0003] At present, taking the exercise mode of the exerc...

Problems solved by technology

[0003] At present, taking exercise bike riding as an example, the speed of the resistance wheel changes at any time, and the current also fluctuates randomly, which will cause the resistance torque generated by the electromagnetically controlled resistance wheel to be unstable and unbalanced, making people feel when riding. The torque is unstable, unbalanced, heavy and light, which affects the experience and fitness effect

In this regard, the existing solution is to obtain a reference value by comparing statistical methods to adjust the current input to the electromagnet to adjust the torque when the resistance wheel rotates. However, this method cannot be applied to every electromagnetic control. Resistance wheel (different electromagnetic control resistance wheels have differences, under the same current, the resistance torque produced by each electromagnetic control resistance wheel is different, and the corresponding resistance torque is also different under different speeds and different currents), adjust the resistance generated by the current according to this The torque will have problems such as insufficient stability, insufficient balance, and deviation in accuracy.
