【detailed description】

Specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. As shown in FIG. 1, an implementation of a brainwave data transmission system includes a brain wave detector, a client for brain wave detection analysis, and a server for brain wave detection analysis. The brain wave detector is connected to the client by wired or wireless connection, such as: Bluetooth communication, wiFH3⁄4, optical fiber communication, coaxial cable communication, serial communication and parallel communication; the client can communicate with the Internet, LAN, mobile communication network, etc. Server connection.

The brain wave detector is used to detect brain wave signals. For example, the hair with the publication number CN101677774A can be selected! Apply for a disclosed head-mounted portable brainwave detector. The brainwave detector includes at least a frame mountable to a user's head, one or more dry active sensors on the frame for detecting an original brainwave analog signal of the user, and processing the original brainwave analog signal as a representation A processing unit for real-time brainwave digital signals of the user's mental state. The processing unit of the brain wave detector can use the NeuroSky company to produce the ThmkGear series of brain wave processing chips, which can process the original brain wave analog signals and calculate the following real-time brain wave data values per second. _:

l, Att _: Concentration value, this unsigned one byte value indicates the user's current "Attention" index, that is, the intensity of the user's "concentration" level or "attention" level, for example, when You can enter a highly focused state and you can control your mental activity steadily. The value of the index will be high. The index value ranges from 0 to 100. Mental states such as upset, mental paralysis, inequality, and anxiety all reduce the Att value.

2, Med value: Relaxation value, this unsigned one byte value indicates the user's current "meditation"

(Meditation) Index, which is the level of user's "calmness" or "relaxation". The value of the index is 0 to 100. The value of Med reflects the mental state of the user, not his physical state, so Simply relaxing the whole body muscle does not quickly increase the Med value. However, for most people, in normal circumstances, physical relaxation usually helps to relax the mental state. Increased level of meditation and brain activity There is a clear correlation between the reductions. Long-term observations show that closing the eyes allows the brain to reduce the level of mental activity in the brain without having to deal with the sight seen through the eyes. Therefore, closing the eyes is usually an effective way to increase the value of Med. Mental states such as mental paralysis, anxiety, and anxiety, as well as sensory stimuli, will lower the Med value.

Further details of the Thiiikgear series of brainwave processing chips are available at -htt :〃 www.neurosky.com.cn/kfz—newsadetail.aspx?Newsn>=58. It can be understood that in addition to the above-mentioned head-mounted portable brain wave detector, the brain wave detector can also use a desktop or other type of brain wave detector, and the brain wave detector can also use other brain wave processing chips, and only need to be able to It is sufficient to output the above-mentioned Att value concentrated force value) and the Med value (relaxation force value).
