Servo motor torque control system in fitness rehabilitation instrument and control method

Abstract

The invention discloses a servo motor torque control system in a fitness rehabilitation instrument and a control method. The system comprises a fitness rehabilitation instrument, a servo motor, an intelligent control panel, an identity recognition module, a main controller, a cloud server and a sensor, wherein the servo motor is connected with the fitness rehabilitation instrument and used as a resistance device of the fitness rehabilitation instrument; the main controller is used for controlling the torque of the servo motor according to preset target resistance parameters and current user exercise information detected by a sensor in real time. The system has the effects that constant torque control can be provided, the problems that resistance generated in a conventional weighing mode islarge in inertia, speeds cannot be changed too rapidly in the exercise process, and the explosive power exercise effect is not good, can be solved, the torque can be controlled according to parametervariations, the problem that the resistance generated in the conventional weighing mode is not applicable to the whole exercise process, and only single exercise modes are available, can be solved, resistance curves (parameters) are stored in the main controller or a cloud service platform, the system is customized for users by exercise experts or rehabilitation doctors, and scientific healthy training can be provided for users.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a servo motor torque control system and control method in fitness and rehabilitation equipment. Background technique [0002] At present, domestic strength training equipment generally has problems such as single load, large starting inertia, unstable process force, and low degree of automation. How to integrate modern advanced servo motor control technology into sports rehabilitation training equipment and change the current fitness rehabilitation equipment It is common to use metal weight plates or physical equipment to adjust the friction method to adjust the current situation of exercise intensity. [0003] In fitness rehabilitation treatment, appropriate exercise intensity and methods are particularly important. In the current rehabilitation treatment, rehabilitation patients exercise with bare hands or simple equipment, and at the same time need rehabilitation doctors t...

AI Technical Summary

Problems solved by technology

[0004] The present invention firstly provides a servo motor torque control system in fitness rehabilitation equipment. The system generates different torques through the servo motor to simulate the fitness rehabilitation equipment with different loads, so that it can provide users with resistance under different postures, and solve the problem Traditional fitness equipment counterweight, air resistance or electromagnetic control flywheel resistance system has the problem of inconstant resistance caused by its own mass with the acceleration of movement.
