Embodiment

[0021] Embodiment: sound and light feedback safety alarm device

[0022] like figure 2 As shown, the device is composed of an EEG acquisition module, an EEG amplification filter conversion module, an EEG analysis and calculation module, a real-time analysis data and baseline value comparison module, an alarm threshold setting and activation module, and an alarm reminder module.

[0023] ●The EEG signal is very weak, the amplitude range: 20V~200V, the frequency range: 1~30Hz. In addition, EEG signals have the following characteristics:

[0024] 1) The randomness and non-stationarity are quite strong.

[0025] 2) EEG signals are non-linear.

[0026] 3) The background noise of the collected EEG signal is relatively complex, including 50Hz power frequency interference, contact noise between electrodes and skin, and interference of common-mode signals between electrodes and ground, etc.

[0027] ●The whole system consists of impedance test, level measurement, differential ampl...

Abstract

The present invention relates to a safety monitoring prompting device. Said device is characterized by that it can dynamically monitor the cerebral waking state of worker engaging in dangerous operation by means of monitoring electrical activity of brain, and when said device finds that his consciousness state is being in abnormal waking state, it can utilize physical stimulation modes of sound, light, electricity, heat and wind to prompt said worker.

Description

technical field [0001] The present invention relates to a safety monitoring prompting device, in particular to a method for dynamically monitoring the waking state of the brains of workers engaged in dangerous operations by monitoring the state of brain electrical activity, and when it is found that the state of consciousness is abnormally waking , light, electricity, heat, wind and other physical stimuli to remind users. The device can be widely used in any workers who may be in serious danger such as driving, high-altitude operations, and important instrument operations. technical background [0002] Using EEG acquisition technology, four different types of brain waves can be detected when people are in different states of consciousness. When we are in a highly awake state (highly excited and tense state), the brain works on a wave band of 13-25 Hz, called the beta wave state; when we are relaxed and awake (moderately awake), the brain operates at 8-12 Hz In the early st...
