Testing device and analysis method of posture of sailboard

The present invention relates to a test device and windsurfing posture analysis methods, devices including portable measuring instrument onboard, real-time monitor and analyzer. Portable measuring instrument onboard sail positive node and the negative node adhered to sail on the mast, the support rod is connected to packet hoop, hoop package by the locking pin on the mast. Embedded real-time display on the front sail and sail node negative node analyzer is in the coach boat, sail positive node receiving the data uploaded via GPRS communication link, and data processing. Analysis of the device is used to sail positive nodes and nodes synchronous data acquisition board via Bluetooth communication link can be simultaneously measured in windsurfing speed, track parameters, post-processing and data storage display. The present invention is capable of understanding the movement of windsurfing and accurately find a breakthrough to improve Athletes develop more effective training program for the coaches to provide a reliable basis.
