Description
Technical Field
The present invention relates to a device for reading brain waves.
Background
Acquiring electrical brain signals has been one of the important means for studying brain physiology and pathology. The electroencephalograph tester thus developed has been widely used. However, the conventional electroencephalogram reading apparatus has relied on electrodes disposed on the head in contact with the skin to obtain the epidermal potential signal at the portion where the brain is in contact with the electrodes, and then the potential signal is converted into an electrical wave signal by an electronic device, and the electrical wave signal is expressed as various waveform signals on an oscilloscope or a printer. The pulse signal into which one converts such an electrode potential signal is defaulted to a brain wave signal. Obviously, this is not a true brain wave signal.
In order to obtain a more realistic wave signal of the brain, a new electronic device is required. The invention provides a device capable of reading brain wave signals. Further reveals the physiological function of the brain and provides support for brain science research and medical treatment.
Disclosure of Invention

The device comprises a Faraday cage for shielding environment signals, a helmet for receiving electric wave signals, a signal modulation detection system, a signal operation and amplification system, an intelligent signal display, a printer and the like. The Faraday cage is used for shielding the brain wave reading device to eliminate clutter in the external electromagnetic environment from interfering the reception of brain waves. The receiving system is a wearable electronic device designed with multiple built-in patch antennas and a grounded seat or bed. The receiving system transfers the received electric wave signal to the tuning and detecting system, and then transmits the selected signal to the signal amplifying and computing system, after computing and amplifying, it is output to the central processor system and the display system. The central processor and the display system are arranged in a host machine and are composed of the central processor, a database and an intelligent video display screen, and the processor and the database in the system can provide a three-dimensional image model corresponding to brain wave signals, so that an image thinking mode expressed by brain waves at a specific frequency is displayed. The display system is additionally provided with a printer, and printing can be performed.

The chip antenna group (9) arranged in the helmet can receive signals of different parts of the head, the tuning detection system (3) is internally provided with the coil group (10) and the detection chip group (11) to detect brain wave signals, and transmit the detected brain waves to the operation amplification system (4) for operation and signal amplification, and after the brain waves are processed by the central processing unit (6), the output end of the operation amplification system is subjected to screen display and printing. An intelligent arithmetic unit (12), an information database (13) and a display screen (14) are arranged in the central processing unit (6), and the signals can be three-dimensionally and visually assembled by comparing and calculating the received information with a large amount of stored data so as to obtain an image thinking model of the signals. Or the obtained information can be processed into a corresponding file and then printed.
Detailed Description
As an example of implementation, the Faraday cage is a metal net cage which is formed by copper wire net plates and has the area of 12 square meters and the height of 3 meters. The brain wave receiving device is a helmet-type receiver. In the sandwich of the helmet, 3 groups of patch antennas are placed, which can be connected individually or selectively in series to transmit the received signal to the tuning detection system through a cable. The tuning vibration detection system consists of 3 groups of coils, and the wire diameters and the turns of the three groups of coils are respectively set according to a high-frequency band, a middle-frequency band and a low-frequency band so as to ensure that various brain wave signals can be received. The detector is composed of a chip set, filters the detected electric waves at the same time, and then outputs the electric waves to the operational amplifier. The detected brain wave signal is amplified through operation and then transmitted to a central processing unit for comparison and calculation, and the obtained information can be printed through a printer in the form of waveform, frequency, three-dimensional simulation and other information, and can also be displayed through an intelligent display.
The intelligent central processing unit has the capability of performing 3D image conversion on the signals, and the received signals are compared with a large amount of information in the database, so that a three-dimensional image model corresponding to the information can be assembled. This is significant in dealing with the dream signal during sleep.
