Research on the Key Technologies of Electronic Test Equipment for Training Assistance to Surfing Coach

By adopting the combination of the modern wireless communication, the sensor and embedded system, we are aiming to establish various key technological indicators above the water for surfing players. Moreover, by developing coach´s portable equipment for training assistance, we try to fix instant indicators and help the coach to control water athletes´ exercising conditions and training effects. The paper has described the design principles and the key technologies of the system in details and carried out theoretical and practical verifications on the testing results of sample equipment. The result is that, this training equipment has a good performance which matches with same foreign products in technological levels, and its functions display more integrity and creativity.
