System for dynamically measuring heat consumption of riding by calorie

The invention discloses a system for dynamically measuring heat consumption of riding by calorie, which is characterized by consisting of a friction generator which forms friction with a bicycle wheel and outputs an alternating current, a power supply treatment module which provides a system power supply, a signal acquisition module for acquiring dynamic data information of riding, a signal processing module which calculates a caloric value and riding parameters, and a man-machine interaction module which displays the operation mode and dynamic data information of the signal processing moduleand shifts modes. When the friction generator provided by the invention is used for calculating the running speed of the bicycle, the dynamic data information can be obtained by a corresponding sensor, so the result of the measurement is accurate and reliable.
