Embodiment 1
[0033] Such as Figure 1-2 Shown, anti-trance bracelet of the present invention, vibration sensor module 1, control module 2, vibration module 3, timing module 5, communication module 4 and storage module; Connection; the control module 2 is used to receive the vibration sensor signal and control the vibration of the vibration module 3; the timing module 5, the communication module 4, and the storage module are connected to the control module 2 respectively.
[0034] The timing module 5 is directly connected to the control module 2, or the timing module 5 is connected in series between the vibration module 3 and the control module 2; the control module 2 is used to start the timing function of the timing module 5, and the vibration module 3 vibrates after timing. The design of the timing function can realize comparison and judgment through time delay, avoid misjudgment of the dazed state caused by the stop of instantaneous vibration, and increase the accuracy of judgment. The p...
Embodiment 2
[0040] Based on the anti-trance bracelet of embodiment 1, its anti-trance method is:
[0041] The control module 2 collects the vibration signal through the vibration sensor module 1; when the vibration signal is less than the set value, the control module 2 controls the vibration of the vibration module 3 or controls the vibration of the vibration module 3 after a delay. If the vibration signal reaches the set value during the delay, then Interrupt delay.
[0042] The method can vibrate in time to send a reminder signal, can effectively realize the rapid detection and quick reminder of the device in a daze state, and can quickly judge the amount of daze vibration by comparing the set values, and then through the internal delay of the control unit or connected to it The timing module 5 quickly judges the state of trance, improves the detection speed and efficiency of the device, and at the same time, effectively reduces the structural complexity of the device, reduces the cost...
Embodiment 3
[0044] Based on the anti-trance bracelet of embodiment 1, its anti-trance method is:
[0045] Step 1: After wearing the wristband, the temperature sensor or photoelectric sensor sends a signal to the control module 2, so that the control module 2 enters the working state from the standby state;
[0046] Step 2: The control module 2 receives the vibration signal from the vibration sensor module 1. When the vibration frequency of the vibration signal is lower than 5HZ and the vibration amplitude is less than 0.9cm, the control module 2 controls the timing module 5 to perform timing for 8-12s. , the control module 2 determines that the bracelet user is in a daze state; otherwise, it is judged to be in a non-trance state;
[0047] Step 3: In the timing process, the control module 2 continues to receive the vibration signal of the vibration sensor module 1, when the vibration frequency of the vibration signal is lower than 5HZ and the vibration amplitude is less than 0.9cm, the tim...
