Embodiment Construction

[0028] Exemplary embodiments of the present invention will be described below with reference to the accompanying drawings. In the interest of clarity and conciseness, not all features of an actual implementation are described in this specification. It should be understood, however, that in developing any such practical embodiment, many implementation-specific decisions must be made in order to achieve the developer's specific goals, such as meeting those constraints related to the system and business, and those Restrictions may vary from implementation to implementation. Furthermore, it should also be understood that development work, while potentially complex and time-consuming, would at least be a routine undertaking for those skilled in the art having the benefit of this disclosure.

[0029] Here, it should also be noted that, in order to avoid obscuring the present invention due to unnecessary details, only the device structure and / or processing steps closely related to t...

Abstract

The invention discloses a minimized low-power-consumption electroencephalogram collecting and wireless transmission device. The device comprises an electroencephalogram collecting module, a storage display module and a wireless charging module; the electroencephalogram collecting module collects the electroencephalogram through a needle electrode unit, and the electroencephalogram is sent to a signal processing unit to amplify and filter, and the signal after being processed by the signal processing unit is output to a storage display module through a first DA 14580 Bluetooth wireless transmission unit; the storage display module receives the signal output by the first DA 14580 Bluetooth wireless transmission unit through a second DA 14580 Bluetooth wireless transmission unit; the signal is stored in the first SD card unit, and digitally filtered through a STM32F103RCT6 microprocessor unit, so as to store the signal after digital filtering to the second SD unit; at last, the signal is displayed through the LCD display screen.

Description

technical field [0001] The invention relates to an electroencephalogram signal acquisition technology, in particular to a miniaturized low-power consumption electroencephalogram signal acquisition and wireless transmission device. Background technique [0002] The acquisition and research of EEG (Electroencephalogram) provides the basis and foundation for human beings to obtain brain information, treat brain diseases, and help the disabled in their daily lives. Various disciplines such as science and informatics also have far-reaching significance and influence. Acquisition and research of animal EEG signals is a common method for people to conduct brain science research. Therefore, the acquisition equipment for animal EEG signals has always been a research hotspot. The main frequency of the EEG signal is 0.5-100Hz, and the signal amplitude range is 5-300μV. Since μV-level EEG signals are quite weak, they are easily overwhelmed by mV-level external interference and interna...
