Problems solved by technology

[0002] With the promotion of national health and fitness for all, more and more outdoor fitness equipment is installed all over the country. Human limb strength training is an important item of fitness. A permanent magnet self-generator with low-speed, low-voltage, and high-current power generation capacity is used as resistance. The resistance source of the trainer is an option to ensure safe short-stroke movement, but the large current backflow generated by the permanent magnet self-generator during fast movement will also demagnetize and damage its magnets while providing resistance; in addition, due to changes in movement speed The induced current change will change the resistance, and deviate from the resistance level set value; this has become the defect of using permanent magnet self-generator

Abstract

The invention relates to a control circuit and a control method for an outdoor resistance training device, and solves the problems that a magnet is demagnetized and damaged while resistance is provided by large current backflow generated by a permanent magnet self-generator in fast movement through the design of the control circuit and the control method; and the current change caused by the change of the movement speed changes the resistance and deviates from the resistance level set value. The control circuit comprises a permanent magnet self-generator, a rectifying and filtering unit, a backflow adjusting unit, a sampling and digitizing unit and a central control unit, wherein the permanent magnet self-generator, the rectifying and filtering unit and the backflow adjusting unit are electrically connected in sequence and then are connected to the central control unit; and the input end of the sampling and digitizing unit is electrically connected with the backflow adjusting unit, and the output end of the sampling and digitizing unit is connected to the central control unit.
