Embodiment 1

[0016] Embodiment 1: this intelligent safe comprises wireless brain computer earphone and cabinet body, as figure 1 As shown, the surface of the cabinet is provided with a display screen and buttons, and the interior of the cabinet is provided with a microprocessor connected to the display screen and buttons; the wireless EEG earphone is used to collect the user’s EEG signals, Corresponding preprocessing, and transmit the signal to the microprocessor via Bluetooth; the microprocessor is equipped with a Bluetooth receiving device and a buzzer, which is used to identify the received EEG data, obtain password instructions, and combine keystrokes The information realizes the opening and closing control of the safe. The buttons on the surface of the cabinet include switch, confirm, collect EEG, re-collect, reset password and numbers 0-9.

[0017] Such as figure 2 As shown, the wireless EEG headset includes an electrode module, a preprocessing module, a signal conversion module, ...

Embodiment 2

[0018] Embodiment 2: The smart safe needs to set the corresponding relationship between corresponding motor imagery and corresponding letters in advance, where the letters include a, b, c, d, e, and f, and the corresponding relationship between these 6 letters and motor imagery , the default is that the letter a corresponds to the motor imagery of the left hand, b corresponds to the motor imagery of the right hand, c corresponds to the motor imagery of the left foot, d corresponds to the motor imagery of the right foot, e corresponds to the motor imagery of the tongue, and f corresponds to mental arithmetic. The types of motor imagery and the corresponding training can be realized according to the methods in the prior art. The user can randomly select the required number of letters from the 26 letters according to the actual needs and configure the corresponding motor imagery from the above 6 kinds of motor imagery. If the user wants to change the corresponding relationship, he...

Embodiment 3

[0020] Embodiment 3: When the password is all numbers such as 123456, when the user enters the "Please enter the password" interface, the user can directly press 123456, and then click the "OK" button, and the safe will open;

[0021] When the password is a combination of numbers and letters such as a1b234, when the user enters the "Please enter the password" interface, first press the button "Collect EEG". At this time, the microprocessor will display the corresponding letter a on the screen after data analysis. The corresponding motor imagery will be replaced by a "*" after 2 seconds. At this time, the user presses "OK" to enter the next password. If the recognition subtitle is wrong, press "Re-collect" until it is correct. The next step is the user You can directly press "1" to enter the third password input, press "Collect EEG", repeat the same collection steps as letter a, the screen displays the corresponding letter b, click "OK" to enter the next password input, Then th...

Abstract

The invention relates to an intelligent safe case based on a motor imagery brain-computer interface, and belongs to the technical field of human-computer interaction. The device comprises a case body, a wireless brain electric earphone, a display screen, keys and a micro processor. A user wears the wireless brain electric earphone, Bluetooth is used for being connected with the micro processor in the safe case, an unlocking program of the safe case is started, then decoding is conducted according to prompts of the display screen installed on a case door and motor imagery, and accordingly a door lock of the safe case is opened. The motion imagery brain computer interface technology is combined with the design of the safe case, so that the design of the safety case is more diversified, and meanwhile, property of a user is protected more efficiently. The device has the advantages of being high in security protection capability, more diversified in password, good in use reliability and easy to use.

Description

technical field [0001] The invention relates to an intelligent safe based on a motor imagery brain-computer interface, belonging to the technical field of human-computer interaction. Background technique [0002] The brain-computer interface is a communication system that people can use to record brain waves in real time, interpret the thinking of the brain to a certain extent, and translate them into control commands to control computers, household appliances, robots and other equipment. It is to establish a new type of direct communication channel between the human brain and electronic devices, such as computers. Through this channel, people can express ideas through the signals generated by the brain in order to convert them into control commands to provide more convenience and comfort to people's lives. entertainment and improve people's quality of life. [0003] Motor Imagery is one of the important control methods in brain-computer interface technology. This method ma...
