ABSTRACT:
A dynamic information monitoring system for skiing exercise includes an acceleration sensing module for detecting an acceleration signal of a skier during skiing, a GPS signal receiving module for receiving a GPS signal, a microprocessor for receiving the GPS signal received by the GPS signal receiving module and the acceleration signal detected by the acceleration sensing module, and a display unit connected to the microprocessor for showing dynamic information about a skier in skiing. The microprocessor converts data strings of the speeds over ground or times and coordinate positions in the GPS signal received by the GPS signal receiving module into real moving speeds of the skier during skiing, and calculates the acceleration of the ski. The uphill and/or downhill inclination angle and height of a ski of the skier is calculated based on the acceleration of the ski, the acceleration signal received by the acceleration sensing module as well as the acceleration of gravity.
