The invention discloses an EMS resistance controller. The EMS resistance controller comprises a switch power module, a power supply driving module used for carrying out driving management on the switch power module, a DC output module connected to the power supply driving module, a DC / DC converter, a voltage sampling module and a constant current driving module, wherein the DC / DC converter, the voltage sampling module and the constant current driving module are connected to the output end of the DC output module. The voltage sampling module collects changing conditions of the voltage output by the DC output module in real time and feeds back the changing conditions to the power supply driving module to make the power supply driving module adjust the oscillation frequency of the DC output module. A buffering module connected to the output end of the DC / DC converter is provided with a control signal input interface and a speed sensing signal input interface, wherein the control signal input interface is electrically connected with a control mechanism of a magnetic control vehicle, and the speed sensing signal input interface is electrically connected with a motor of the magnetic control vehicle. The constant current driving module is connected to the output end of the buffering module through a current amplification module, and the current sampling module is connected to the output end of the constant current driving module and used for collecting current signals of an electromagnet of the magnetic control vehicle in real time. A linear mode is adopted by the EMS resistance controller for adjustment, and accurate control over the motor of the magnetic control vehicle can be achieved.
Description
technical field [0001] The invention relates to the technical field of magnetic control vehicle control, and specifically provides an EMS resistance controller. Background technique [0002] The magnetic control car is a popular fitness equipment. It adjusts the resistance of the magnetic control car by controlling the distance between the magnet of the magnetic control car and the metal flywheel, so as to achieve the requirements of different exercise intensities. [0003] The way to adjust the resistance of the traditional magnetic vehicle is as follows: the user controls the speed of the magnetic vehicle motor through the control mechanism, and then the motor controls the distance between the magnetic vehicle magnet and the metal flywheel by rotating the cable or the principle of leverage. Realize the adjustment of the resistance of the magnetic control vehicle. However, the control mechanism of the traditional magneto-controlled vehicle lacks the precision of motor cont...
