The sense of rhythm, the most efficient use of the player's muscle strength, delay the occurrence of muscle fatigue, and reduce the impact of tremor, improve the level of performance on the spot. [Prior Art] In the past, most of the coaches relied on the coach to understand the stability of the archers. They were evaluated by experience, or the researchers used electromyography (EMG) to measure and record the changes in the muscles of the players. To evaluate the stability of the archery player's moment of shooting, and to confirm that the standard deviation of the amplitude of the arrow tip is large, which is one of the factors affecting the score. However, there are two problems in this way. The former is the evaluation of the coach and not objective enough. The subtle changes in the player's movements cannot be immediately detected. The latter is to measure the results of the EMG changes measured by E M G, and then inform the players for some time. The players may have forgotten the feeling at the time. 'The technical level is still not perfect and needs further improvement. The present inventors have invented the invention in view of the disadvantages of the prior art, and after the continuous improvement of the experiment, the invention has been successfully developed. Therefore, how to provide a sensor using an accelerometer as a signal for measuring the tremor signal, the player The acceleration changes caused by the trembling of each part of the arm are converted into sound through a self-developed algorithm. This sound signal is used as a stimulus source for biological feedback, and the player and the coach are immediately informed to change the current posture 201010765 and the strategy 'keep the moment. Stability is the technical focus of the present invention. SUMMARY OF THE INVENTION To achieve the foregoing objective, an athlete feedback diagnosis system of the present invention has a main system architecture including an acceleration sensor, an analog-to-digital device (ADC), a regulator, and a number of position assistants (pDA). A digital analogizer (DAC), a sound signal, the athlete feedback diagnosis system, the action flow: © its multi-channel acceleration sensor is fixed on the left and right arms of the player, and then the analog acceleration signal is amplified. It is converted into a digital signal by an analog-to-digital device (ADC), and the self-developed algorithm is used to analyze the overall tremor status of the current player, and the index parameters of different weights are combined to obtain a stable score. Then, a digital signal is output to the player via the digital analogizer (MC) to correct the current posture. In the beginning, we will directly transmit the multi-channel Tremor signal to the portable signal collector (such as PDA) via Bluetooth technology, and analyze the signal with a program written by ourselves, which can be more flexible to develop and judge. The algorithm of player stability. After the algorithm matures and is converted to the microcontroller for execution, the cost of the system can be further reduced. The focus is on the assistance and early warning of the system, reminding the player to adjust his most suitable bowing posture during the normal practice. The sense of perception of the shooting process will make the most efficient use of the archer muscle strength, delay the occurrence of muscle fatigue and reduce the impact of tremor, and improve the level of performance on the spot. [Embodiment] In order to make the other members of the present invention more convenient to understand the other features and advantages of the present invention, and to achieve the 201010765 effect, the present invention will be described in detail with reference to the accompanying drawings. For the athletes to give back the overall system architecture diagram of the diagnosis system, as can be seen from the figure, the acceleration of the multi-channel is set on the left and right arms of the player 9, and the acceleration signal is amplified by the analog signal (ADC) 2 The digital signal is firstly analyzed by the low-power wireless network system 8' to the self-developed algorithm in the regulator 31, and the tremor status of the current player Zhao is analyzed, and the index parameters of different weights are integrated to obtain a stability. The score is then corrected by the digital analogizer (MC) 4 to the ifc-sound signal to the player to correct the current position. In the beginning, we transmitted the stimuli k of the direct channel to the portable signal collector (such as notebook computer (n〇teb〇〇k) 33) via Bluetooth technology, and analyzed the signal by our own program. It is more flexible to develop an algorithm for judging player stability. By the time the algorithm is mature, switching to the regulator 31 for execution can further reduce the cost of the system. The fixed point of the acceleration sensor 1, the fixed mode, and the selection of the index parameters need to be determined by actual discussion with the player, the coach, and the results obtained by the on-site Dong measurement, wherein the sound signal is converted by the earthquake-to-sound audio system 6. .

A score of stability is then output via the digital analogizer (DAC) 4 to the player to correct the current pose. In the beginning, we will directly transmit the multi-channel tremor frequency (Trem〇r) 7 signal to the portable signal collector (such as the personal digital assistant (pda) 32) via the Bluetooth technology, and use the program written by ourselves to perform the signal. The analysis can be more flexible to develop an algorithm for judging player stability. After the algorithm matures, switching to the regulator 31 for execution can further reduce the cost of the system. The fixed point of the acceleration sensor 1, the fixed mode, and the selection of the index parameters need to be determined by actual discussion with the player, the coach, and the on-site measurement, wherein the sound signal 5 is converted by the Zhenyan to audio system 6. . _ From the above, the advantages of the present invention are as follows: 1.
