[0067] Compared with the prior art, the present invention has the following beneficial effects:

[0068] 1. The present invention proposes a smart wristband with fatigue reminder and method thereof. In the prior art, smart wristbands often lack certain fatigue reminder functions, which may cause the wearer to become overly tired. However, the wristband of the present invention is internally provided with a sensor unit, a microprocessor, a wireless communication unit, a power module, and a vibration unit. The sensor unit detects the wearer's physical condition value, sends the detection result to the microprocessor for processing, and determines the wearer's fatigue status. The microprocessor then sends different signals to the fatigue reminder system based on the wearer's fatigue status to remind the wearer of fatigue.

[0069] 2. The present invention proposes a smart wristband with fatigue reminder and method thereof. In the prior art, once the wristband wearer enters a fatigue state while performing tasks that require concentration, it may pose a great danger. The fatigue reminder system of the present invention includes a status receiving module, an information preset module, a fatigue reminder module, a signal transmission module, and an instruction sending module. The fatigue reminder system is configured to emit different fatigue signals according to the wearer's fatigue level. Through vibration and voice reminders, the wearer can receive corresponding reminders when the body enters different degrees of fatigue, preventing the user from becoming overly fatigued, improving the user experience, and avoiding excessive fatigue that may affect the wearer's physical health, or the danger of fatigue when performing tasks that require high concentration, such as driving.

[0070] 3. The present invention proposes a smart wristband with fatigue reminder and its method. In the prior art, smart wristbands often have poor fatigue detection effects. However, the sensor unit of the present invention includes a heart rate sensor module, a blood oxygen sensor module, an electromyography sensor module, and a pressure sensor module. The sensor unit is configured to sense and detect body status values ​​including heart rate, blood oxygen, electromyography, and muscle tightness. When the human body enters a fatigue state, various body numerical indicators will change accordingly. Analysis based on the values ​​obtained by the sensor unit makes the detection and judgment of the wearer's fatigue state more accurate.

[0071] 4. The present invention proposes a smart wristband with fatigue reminder function and its method. In the prior art, the reminder function provided by the smart wristband is easily ignored by the user, resulting in the wristband being unable to provide an effective reminder function and being useless. The wireless communication unit of the present invention includes a wireless network module and a Bluetooth module. The wireless communication unit can send signals to the user terminal device and issue pop-up reminders through the user terminal device, so that the wearer can understand his or her fatigue status in real time while working, and appropriately relax and adjust to reduce and relieve his or her fatigue level, combine work and rest, and improve the wearer's control and understanding of his or her physical health status.

[0072] 5. The fatigue reminder smart bracelet and method proposed in the present invention accurately obtain the wearer's fatigue behavior experience by analyzing the acquired signal data, and at the same time generate a corresponding monitoring report to accurately record the wearer's fatigue behavior experience, thereby ensuring the accuracy of the wearer's reminder.

[0073] 6. The fatigue reminder smart bracelet and method proposed in the present invention help to accurately obtain the data transmission error rate by calculating the data transmission delay, thereby evaluating the data transmission efficiency of the wireless communication unit based on the data transmission error rate. At the same time, the data transmission efficiency accurately measures whether the data transmission of the wireless communication unit is qualified, thereby improving the timeliness of monitoring the data transmission of the wireless communication unit, and also helping to improve the accuracy and efficiency of data transmission when the wireless communication unit is transmitted to other user terminal devices.
