進一步來說，在處理器120計算出運動器材的運動特徵資訊SFI之後，處理器120可以接續比較運動特徵資訊SFI以及標準運動特徵資訊SIFO以獲得比較結果CR。接著，處理器120可依據比較結果CR以判斷出運動器材當前的運動型態，並對應地產生提示訊息PM至通訊裝置140。Furthermore, after the processor 120 calculates the motion characteristic information SFI of the sports equipment, the processor 120 may continue to compare the motion characteristic information SFI and the standard motion characteristic information SIFO to obtain the comparison result CR. Then, the processor 120 can determine the current movement pattern of the sports equipment based on the comparison result CR, and generate a prompt message PM to the communication device 140 accordingly.
舉例來說，當處理器120依據比較結果CR判斷出啞鈴處於鍛鍊二頭肌部位之運動型態時，處理器120可依據此運動型態以及對應的運動特徵資訊SFI以產生提示訊息PM至通訊裝置140。其中，本實施例的提示訊息PM可例如是指示運動者目前鍛鍊的部位以及運動器材在該運動型態下的運動快慢、動作幅度、消耗能量與正確度等相關資訊。For example, when the processor 120 determines that the dumbbell is in the movement pattern of exercising the biceps based on the comparison result CR, the processor 120 can generate the prompt message PM to the communication based on the movement pattern and the corresponding movement characteristic information SFI. Device 140. The prompt message PM in this embodiment may, for example, indicate the part where the athlete is currently exercising and related information such as the speed, range of motion, energy consumption and accuracy of the exercise equipment in the exercise mode.
在另一方面，通訊裝置140可經由藍芽通訊協定以無線的傳輸方式來與行動裝置160進行通訊。在實際的應用上，行動裝置160可以透過應用程式（APP）或圖型化介面（GUI）來對運動監測裝置100的處理器120進行相關設定，並對應地提供設定訊號SS至通訊裝置140與處理器120。相對的，通訊裝置140可以以無線的傳輸方式來將提示訊息PM提供至行動裝置160，以使行動裝置160可依據提示訊息PM來顯示與紀錄運動者的運動資訊。On the other hand, the communication device 140 can communicate with the mobile device 160 through wireless transmission via Bluetooth communication protocol. In actual applications, the mobile device 160 can perform relevant settings on the processor 120 of the motion monitoring device 100 through an application program (APP) or a graphical interface (GUI), and correspondingly provide the setting signal SS to the communication device 140 and Processor 120. In contrast, the communication device 140 can provide the prompt message PM to the mobile device 160 through wireless transmission, so that the mobile device 160 can display and record the athlete's sports information according to the prompt message PM.
順帶一提的是，在另一些實施例中，運動監測裝置100可以更包括肌電信號感測器（Electromyography Sensor，EMG sensor）（未繪示）。所述肌電信號感測器耦接至處理器120。運動監測裝置100可透過兩個電極貼片來監測運動者的肌肉狀態，並對應地產生肌電信號至所述肌電信號感測器。藉此，處理器120可依據比較所述肌電信號與一參考值以判斷運動者的疲勞程度。其中，當所述肌電信號的大小大於或等於所述參考值時，表示運動者的肌肉已呈現疲勞狀態，此時運動監測裝置100可透過提示訊息PM來建議運動者需停止相關訓練。Incidentally, in other embodiments, the motion monitoring device 100 may further include an electromyography sensor (EMG sensor) (not shown). The myoelectric signal sensor is coupled to the processor 120 . The exercise monitoring device 100 can monitor the athlete's muscle status through two electrode patches, and generate electromyographic signals to the electromyographic signal sensor accordingly. Thereby, the processor 120 can determine the fatigue level of the athlete based on comparing the electromyographic signal with a reference value. When the size of the electromyographic signal is greater than or equal to the reference value, it means that the athlete's muscles have become fatigued. At this time, the sports monitoring device 100 can advise the athlete to stop relevant training through the prompt message PM.
依據上述的說明可以得知，在本實施例中，運動者可以透過行動裝置160來依據提示訊息PM而得知目前的運動情形，且可藉由運動監測裝置100所提供的相關資訊與建議來進行動作上的調整，以提升整體的運動效果。此外，若運動者想要更換運動器材來進行運動，也僅需要將運動監測裝置100重新貼附於另一健身器材的特定位置上即可重新進行監測動作，使得運動監測裝置100能夠應用於不同的健身器材上，並且可以提升運動者在透過健身器材進行特定運動型態時的便利性。According to the above description, it can be known that in this embodiment, the athlete can know the current exercise situation through the mobile device 160 according to the prompt message PM, and can use the relevant information and suggestions provided by the exercise monitoring device 100 to Make movement adjustments to improve the overall movement effect. In addition, if the athlete wants to change sports equipment for exercise, he only needs to reattach the sports monitoring device 100 to a specific position of another fitness equipment to perform the monitoring action again, so that the sports monitoring device 100 can be used in different applications. on fitness equipment, and can improve the convenience of athletes when performing specific exercise types through fitness equipment.
