The control module includes an acquisition module, which is used to acquire the trainee's heart rate parameter data set, rotation rate data set, pressure parameter data set and blood oxygen content, as well as the real-time value and historical value of the corresponding data; a database module, which is used to analyze the trainee's heart rate parameter data set, rotation rate data set and pressure parameter data, and acquire the trainee's training state reference value; a rope resistance compensation parameter control model module, which is used to construct a rope resistance compensation parameter control model, and acquire the historical value of the trainee's training state reference value, and mark it with a timestamp to form a data set, and use the data set to supervise the training, verification and testing of the rope resistance compensation parameter control model until the accuracy of the rope resistance compensation parameter control model meets the preset requirements, and the constructed rope resistance compensation parameter control model is obtained; according to the rope resistance adjustment control database, the real-time value of the trainee's training state reference value is acquired, and the constructed rope resistance compensation parameter control model is input to obtain the rope resistance real-time compensation parameter, which is used to control the electromagnet to provide resistance for the rope.
