| The weight transfer is one of the most important parameters in the process of golf swing and high-quality weight transfer graph is the major reference to judge the normalization of actions. As golfing is widespread, it's significant to design weight transfer analyzer suitable for the public to practice their golfing skill.The weight transfer detecting system is introduced in this paper. The strength of two legs can be tested by weighing sensor of which the signal processing circuit is designed. The system, using 32 bits low power consumption microprocessor LPC2368 of ARM7TDMI-S as the control core and the uC/OS_II as the embedded operating system, can display and analyze the weight transfer data. The hardware circuit is constituted mainly by the sections of data collecting, core processor, displaying, data storing and power supplying. The function is that the output data from the weighing sensor will be extracted after the enlargement and filtration and then be transformed into digital signal by A/D converter and be uploaded to PC through serial port and be analyzed by the PC. At the same time, the analysis of the weight transfer graph can be implemented on the ARM. Data can be displayed on the LCD and stored in the CD card as the form of txt. The software section includes mainly embedding the uC/OS_II operating system for LPC2368 and process the modular design. The interface is designed by using VC++ and then the curve-sorting identifying programme is designed.According to the field debugging, the expected goal of weight transfer data collecting, storing, waveform display and classification etc. is achieved, which provides the basis to the design of the new type golf swing trainers and golf swing analyzer. |
