Description

Technical Field

[0001] The utility model relates to a headband device, in particular to an electroencephalogram recognition headband device, belonging to the technical field of biometric identification. Background Art

[0002] As a new type of biometric feature, electroencephalogram (EEG) signals are electrical signals generated by the activities of neurons in the cerebral cortex. Depending on the individual's brain activity pattern, they have a high degree of individual dependence. At the same time, each individual's thinking state is different and cannot be forged or replicated. Therefore, EEG signals cannot be stolen or forged, and have the unique characteristics of each individual, with uniqueness. Different from biometric features such as fingerprints that are easily affected by external factors, EEG signals have relatively high stability.

[0003] Currently, the existing EEG-based identity recognition and authentication generally perform EEG-based identity recognition based on four categories: resting state, visual evoked potential, motor imagery, and event-related potential. During the identity recognition process, corresponding tasks need to be completed according to requirements to complete the identity recognition. For example, when encountering uncooperative criminals, it is difficult to ensure the accuracy of the identity recognition result, resulting in the unreliability of the existing EEG-based identity recognition and authentication. EEG signal acquisition needs to be carried out under specific task conditions, greatly reducing the universality and practicality.

[0004] Therefore, it is urgent to improve the EEG recognition headband device to solve the above problems. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will cooperate with the drawings and embodiments to detail the implementation manners of the present application, so as to fully understand how the present application uses technical means to solve technical problems and achieve the realization process of technical effects and implement accordingly.

[0022] As Figures 1-4As shown in the figure, the brain pattern recognition headband device provided in this embodiment includes a headband main body 1. An acquisition module installation groove 101 is formed inside the headband main body 1. An EEG acquisition module 2 is fixedly connected inside the acquisition module installation groove 101. The EEG acquisition module 2 is used to capture and collect electroencephalogram signals and transmit them to a computer. The main function of the EEG acquisition module 2 is to amplify, filter, and digitally process these weak bioelectrical signals and transmit them to the subsequent analysis and processing system. The EEG acquisition module 2 is located at the left side position of the headband main body 1. On one side wall of the headband main body 1, a first installation groove 102, a reference electrode installation groove 103, a second installation groove 104, and a ground electrode installation groove 105 are formed. A first active electrode 3 is fixedly connected to the inner wall of the first installation groove 102. A reference electrode 4 is fixedly connected to the inner wall of the reference electrode installation groove 103. The reference electrode 4 is used to establish a potential reference and increase signal comparison. A second active electrode 5 is fixedly connected to the inner wall of the second installation groove 104. The first active electrode 3 and the second active electrode 5 are in contact with the scalp to collect electroencephalogram signals. The recorded electroencephalogram signal is the difference between the active electrode and the reference electrode. A ground electrode 6 is fixedly connected to the inner wall of the ground electrode installation groove 105. The ground electrode 6 is used to reduce interference and balance the potential. The first active electrode 3, the reference electrode 4, the second active electrode 5, and the ground electrode 6 are all electrically connected to the EEG acquisition module 2. One ends of the first active electrode 3, the reference electrode 4, the second active electrode 5, and the ground electrode 6 all extend outside one side wall of the headband main body 1. Through the cooperation of the ground electrode 6 and the electrically connected first active electrode 3, reference electrode 4, second active electrode 5, and ground electrode 6, electroencephalogram signals of the user are collected. The collected data is compared with the input data to determine the identity of the user.

[0023] Secondly, as Figure 3 and Figure 4 shown, the reference electrode installation groove 103 is located at the middle position of the headband main body 1. The first installation groove 102 and the second installation groove 104 are symmetrically distributed on both sides of the reference electrode installation groove 103. The ground electrode installation groove 105 is located at the position away from the reference electrode installation groove 103 in the direction of the second installation groove 104. The heights of the first installation groove 102, the reference electrode installation groove 103, and the second installation groove 104 are flush. The height of the ground electrode installation groove 105 is slightly lower than that of the second installation groove 104. The first installation groove 102 is used to fixedly support the first active electrode 3. The reference electrode installation groove 103 is used to fixedly support the reference electrode 4. The second installation groove 104 is used to fixedly support the second active electrode 5. The ground electrode installation groove 105 is used to fixedly support the ground electrode 6.

[0024] Furthermore, as Figure 1As shown in the figure, a hook surface of a Velcro 7 is fixedly connected to one side wall of the headband body 1. The hook surface of the Velcro 7 is located at the left side position of the headband body 1. A loop surface of the Velcro 8 is fixedly connected to the side wall of the headband body 1 away from the hook surface of the Velcro 7. The loop surface of the Velcro 8 is located at the right side position of the headband body 1. The length of the loop surface of the Velcro 8 is greater than the length of the hook surface of the Velcro 7. The side wall of the hook surface of the Velcro 7 away from the headband body 1 is movably connected to the side wall of the loop surface of the Velcro 8 away from the headband body 1. By the cooperation of the hook surface of the Velcro 7 and the loop surface of the Velcro 8, the headband body 1 is fixed on the head of the user. The size of the headband body 1 can be adjusted by adjusting the position where the hook surface of the Velcro 7 is pasted on the loop surface of the Velcro 8, which is suitable for users with different head diameters and is convenient for wearing the headband body 1.

[0025] Furthermore, as Figure 1 shown in the figure, a sign board 9 is fixedly connected to the side wall of the headband body 1 away from the hook surface of the Velcro 7. The sign board 9 is located at the middle position of the headband body 1. The sign board 9 is used for pasting signs and information transmission.

[0026] As Figures 1-4 shown in the figure, the principle of the electroencephalogram recognition headband device provided in this embodiment is as follows: when a user uses a computer, this electroencephalogram recognition headband device needs to be worn for identity confirmation. The headband body 1 is worn on the head, so that the first active electrode 3, the reference electrode 4, and the second active electrode 5 are located on the upper side of the forehead. Then, the headband body 1 is fixed on the head of the user by the cooperation of the hook surface of the Velcro 7 and the loop surface of the Velcro 8. Then, the electroencephalogram signal is transmitted to the EEG acquisition module 2 through the first active electrode 3, the reference electrode 4, the second active electrode 5, and the ground electrode 6. After being processed by the EEG acquisition module 2, it is transmitted to the computer for data comparison, and the identity of the user can be determined.
