Embodiment 1

[0031] Wireless acquisition system for EEG signal acquisition, such as figure 1 and figure 2 As shown: It includes multiple acquisition terminals for collecting EEG signals at different brain positions. Multiple acquisition terminals are worn on the head in the form of existing EEG caps to collect EEG signals. The acquisition terminals include acquisition modules and processing modules. , conversion module, transmission module and power supply module, the acquisition module signal connection processing module, the transmission module signal connection processing module, the conversion module signal connection processing module, the power supply module is used to supply power to the processing module, and the power supply module can be powered by the power supply in the existing Bluetooth headset The acquisition terminal is wirelessly connected to a recording terminal, and the recording terminal is for the user to carry and wirelessly receive the EEG signal of the acquisition ...

Embodiment 2

[0040] The difference from Embodiment 1 is that the control module also includes a timing unit, the timing unit signal is connected to the control unit, the timing unit timing the EEG signal transmission, the timing unit timing through the internal clock of the control module, the timing duration can be set as required , for example 24 hours, the timing unit sends out a timing sending signal when the timing ends, and the control unit acquires the timing sending signal and obtains the EEG signal in the storage module and sends it to the medical terminal in the background.

[0041] When the abnormal electrode shedding signal and the timing sending signal are obtained at the same time, the control unit of the control module adds a peeling identification segment to the EEG signal, and the control unit sends the EEG signal to the background medical terminal through the communication module when the next timing arrives. Electrical signal, that is, the control unit will send the EEG s...

Embodiment 3

[0045] The difference from Embodiment 1 is that the control unit does not directly send the EEG signal to the judgment unit and the comparison unit, that is, the judgment unit and the comparison unit do not work at the same time, and the control unit first sends the EEG signal to the judgment unit for judgment. When the electrical signal is outside the threshold range, which means that the EEG signal is less than the minimum value, the control unit sends the EEG signal to the comparison unit for comparison.

[0046] The detected EEG signal will be very small due to the electrode falling off or poor contact. At this time, it is only necessary to compare the EEG signal with the lower limit when it is judged that the EEG signal is outside the threshold range and less than the minimum value. When the EEG signal is greater than the maximum value Without comparison, the calculation energy consumption of the system can be saved.

Abstract

The invention relates to the technical field of electroencephalogram signal acquisition, and particularly relates to a wireless acquisition system for electroencephalogram signal acquisition. The system comprises a recording end and a plurality of acquisition ends, wherein the recording end is carried by a user and is used for wirelessly receiving electroencephalogram signals; the acquisition endsare used for acquiring the electroencephalogram signals at different brain positions; the acquisition terminal comprises an acquisition module, a processing module, a conversion module and a sendingmodule. The acquisition module acquires brain electroencephalogram signals and transmits the brain electroencephalogram signals to the conversion module, the conversion module acquires the electroencephalogram signals for conversion and transmits the converted electroencephalogram signals to the processing module, the processing module encapsulates the converted electroencephalogram signals and transmits the encapsulated electroencephalogram signals to the transmitting module, and the transmitting module wirelessly transmits the encapsulated electroencephalogram signals to the recording end for storage. The acquisition end is not directly connected with the recording end through the lead wire to transmit data, so that the movement of a patient is not limited by the lead wire, and the use is more convenient.

Description

technical field [0001] The invention relates to the technical field of EEG signal acquisition, in particular to a wireless acquisition system for EEG signal acquisition. Background technique [0002] The development of information technology in medical technology has made medical technology more and more advanced, and the development of medical technology has also made the diagnosis and treatment of diseases more accurate, convenient and faster. The EEG signal is a spontaneous potential activity generated by the activity of neurons in the brain and always exists. It is an important bioelectrical signal. EEG signals can not only provide a basis for diagnosis of certain brain diseases, but also can be used to assist in judging the efficacy and timely adjusting treatment strategies, such as epilepsy, Alzheimer's disease and hysteria. Therefore, the acquisition of EEG signals is very important. [0003] In the existing EEG signal monitoring system, the EEG signal is collected ...
