Description

Brain wave triggered non-contact alarm device

The technical field is as follows:

the utility model belongs to the technical field of intelligent electron, especially indicate the technique of being applied to in the aspect of the individual safety protection warning, mainly relate to the non-contact warning, specifically are a non-contact alarm device that brain wave triggered for individual safety is guarded against oneself and is reported to the police.

Background art:

at present, portable alarm devices on the market can be divided into four categories: the starting modes of the contact type objects, the induction type objects, the mobile phone App and the intelligent alarm are mostly active triggering, and the mobile phone App and the intelligent alarm are limited by various conditions in emergency, so that the mobile phone App and the intelligent alarm cannot perform set functions due to the fact that active intervention cannot be performed. The object alarm is similar to a wolf-proof alarm, and the product is a small help-calling sound, is mostly made into a small hanging ornament, can send buzzing sound up to 120 decibels by contacting a switch under dangerous conditions, and cannot provide positioning information and the function of emergency help-seeking alarm. The induction type object adopts a passive infrared detector, and the human body close to the induction type object is detected through infrared induction so as to trigger an alarm. The intelligent products such as the intelligent defense alarm afraid of can start the GPS positioning function and the recording function by pressing the switch by the user and collect the position information and the voice information. After the alarm operation is confirmed through feedback, the sound recording and the position information are sent to the mobile phone through the Bluetooth module, and then the information is edited and sent to the storage contact through the mobile phone APP. And if the feedback cancels the alarm operation, stopping the operation. The mobile phone App and other products are more modern than objects, and can trigger an alarm by shaking the mobile phone, plugging an earphone jack and the like, and position and send information to emergency contacts or public security departments.

In the patent design of patent design "portable intelligent security initiative alarm" that patent number is CN206991514U, a portable alarm is disclosed, which comprises a housin, the PCB board, bee calling organ, power and bolt, be provided with a socket on its PCB board, it is corresponding, be provided with a jack on the casing, above-mentioned bolt passes the setting of jack pluggable formula on the socket, under the bolt extracted state, bee calling organ and L ED alarm lamp open, bee calling organ sends the high decibel alarm sound, L ED alarm lamp incessantly glimmers and then scares away the suspect who has illegal intention.

Wearing simulation see fig. 5. The TGAM will read the user's electroencephalogram data in real time after the headband is properly worn, and the TGAM data can be parsed and stored in the Arduino Mega2560 master control board by TGAM communication code in the Arduino Mega2560 master control board. This is the normal state of the device.

After the alarm operation is completed, the user manually enters the mobile phone APP to cancel the alarm state and recover to the normal state.

If the Arduino Mega2560 main control board calculates that the user is in an abnormal state currently through the startle detection algorithm based on the euclidean distance, but the user does not perform the rapid blink operation and the Arduino Mega2560 main control board calculates that the blink frequency of the user is not higher than the set threshold value through the double-downsampling blink detection algorithm, the device is called to enter the calibration state, the Arduino Mega2560 main control board records the maximum value of the euclidean distance in the startle detection algorithm based on the euclidean distance currently as a reference value, the minimum threshold value of the startle detection algorithm based on the euclidean distance is updated to be the reference value, and then the normal state of the device is recovered.
