[0050] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0051] Brain-computer interface technology, as a core technology for exploring the frontiers of brain science and promoting human-computer interaction, has become a commanding point of global technology competition. Its development has made a leap from concept verification to practical application, with a breakthrough from non-invasive to invasive in the technical path, a leap from low flux to high flux in signal transmission, and a transition from wired connection to wireless interaction in system architecture. Non-invasive BCI devices record brain electrical activity through a high-density electrode array on the scalp surface, but the details and spatial resolution of the signal are severely lost after passing through the biological tissue barrier. Invasive BCI implants electrodes into the cortex through surgery and uses a headstage to obtain neural signals, which can accurately detect single or multiple neuron discharges, becoming an important trend in BCI development. In order for the computer to recognize the brain electrical signals collected by the headstage, a signal acquisition and processing device with equally high flux is needed to process these signals and meet different application scenarios.

[0052] Therefore, the present application correspondingly provides a neural signal transmission scheme to improve the flexibility of neural signal transmission and minimize the impact on transmission efficiency.

[0053] Referring to Figure 1 As shown in the figure, the embodiment of the present application discloses a neural signal transmission method applied to a signal processing end, which includes a wired receiving module and a wireless receiving module; the method includes:

[0054] Step S11: determining a target transmission mode from each preset neural signal transmission mode; wherein each of the preset neural signal transmission modes includes a wired transmission single mode, a wireless transmission single mode, and a mixed mode of wired transmission and wireless transmission.

[0055] In this embodiment, the number of the wired receiving modules and the wireless receiving modules is multiple, and the number of the wireless receiving modules is not greater than the number of the wired receiving modules.

[0056] Specifically, the signal processing end includes multiple wired receiving modules and wireless receiving modules, and the number of the wireless receiving modules is not greater than the number of the wired receiving modules. The wired receiving module is specifically a wired receiving port, each wired receiving port can be used independently, and the wireless receiving module is detachable, so the wireless receiving module can be connected or disconnected with the wired receiving port, that is, when the target transmission mode is the wired transmission single mode, the wireless receiving module is controlled to be disconnected with the wired receiving module, when the target transmission mode is the wireless transmission single mode, all wireless receiving modules are controlled to be connected with the wired receiving module, it can be understood that one wireless receiving module is connected with one wired receiving module, instead of multiple wireless receiving modules being connected with the same wired receiving module, when the target transmission mode is the mixed mode of wired transmission and wireless transmission, part of the wireless receiving modules are controlled to be connected with the wired receiving module, and different wireless receiving modules are connected with different wired receiving modules, it can be seen that the wired receiving port ensures the normal use of the basic function of the device, and the signal can be stably collected, the wireless receiving module increases the function of the device on the basis of not affecting the original function, expands the application scene, ensures that the subject can freely move, and the design of the receiving signal mode is suitable for multiple application scenes.

[0057] In a specific case, the signal processing end includes 4 wired receiving modules, i.e. 4 wired receiving ports, each wired receiving port can receive signals of 128 channels, so when all the ports are used at the same time, the device collects signals of 512 channels, the wireless bandwidth is more than 200 Mbps, that is, if it is a wired transmission single mode, the neural signals are received through the 4 wired receiving modules, if it is a wireless transmission single mode, the 4 wired receiving modules are connected with the 4 wireless receiving modules, then the neural signals can be received through the 4 wireless receiving modules, and the received neural signals are forwarded to the 4 wired receiving modules, if it is a mixed mode of wired transmission and wireless transmission, part of the wired receiving modules are connected with part of the wireless receiving modules, so the neural signals are received through the wired receiving modules which are not connected with the wireless receiving modules and through the wireless receiving modules, and the neural signals received by the wireless receiving modules are forwarded to the wired receiving modules, therefore, when the neural signals are transmitted, no matter which mode is selected, signals of 512 channels can be transmitted, so high-throughput signal transmission can be realized.

[0058] In the embodiment, each preset neural signal transmission mode includes a wired transmission single mode, a wireless transmission single mode and a mixed mode of wired transmission and wireless transmission, that is, the embodiment supports wired transmission, wireless transmission and mixed transmission of wired transmission and wireless transmission of neural signals, so that the application scenarios are more flexible.

[0059] It should be noted that in the embodiment, the neural signals of the subjects are transmitted from the signal collection end to the signal processing end, and then transmitted from the signal processing end to the host computer, wherein the transmission of the neural signals is involved, and in order to more reasonably transmit the signals, some processing is also needed for the neural signals.

[0060] Step S12: determining target receiving modules from the wired receiving modules and the wireless receiving modules based on the target transmission mode.

[0061] In the embodiment, the determination of the target receiving modules from the wired receiving modules and the wireless receiving modules based on the target transmission mode includes: if the target transmission mode is the wired transmission single mode, each wired receiving module is determined as a target receiving module, and the wireless receiving modules are controlled to be disconnected from the wired receiving modules.

[0062] Each preset neural signal transmission mode includes a wired transmission single mode, a wireless transmission single mode and a mixed mode of wired transmission and wireless transmission, that is, according to different scene requirements, a suitable target transmission mode can be selected from the modes.

[0063] When the target transmission mode is a wired transmission single mode, that is, only a wired receiving module is needed to transmit the neural signal, all wired receiving modules can be determined as target receiving modules. At this time, the wireless receiving module needs to be controlled to be disconnected with the wired receiving module, and further, the wired receiving module needs to be controlled to be connected with the wired transmission module of the signal acquisition end through an HDMI line (High Definition Multimedia Interface Cable, that is, a high-definition multimedia interface line) so that the current neural signal transmitted by the signal acquisition end can be received through the wired receiving module subsequently. For example Figure 2 the first specific wired transmission mode diagram shown in Figure 3 the second specific wired transmission mode diagram shown in, if the signal acquisition end is provided with only a single head amplifier, that is, the signal acquisition end can only send signals through a single wired transmission port when transmitting signals, at this time, the signal processing end also has only a single wired receiving module connected with the wired transmission module. This case is suitable for a single subject and a scene with low requirement for the activity freedom of the subject, and the wired mode has high signal anti-interference ability, stability and low time delay; if the signal acquisition end is provided with multiple head amplifiers, that is, the signal acquisition end can send signals through multiple wired transmission ports when transmitting signals, at this time, the signal processing end can also have multiple wired receiving modules connected with multiple wired transmission modules, which is suitable for multiple subjects and an experimental scene with low requirement for the activity freedom of the subjects, and can collect the electroencephalogram signals of multiple subjects to improve experimental efficiency.

[0064] When the target transmission mode is a wireless transmission single mode, that is, only wireless transmission is performed, all wireless receiving modules can be determined as target receiving modules, at this time, the wireless receiving module needs to be controlled to be connected with the wired receiving module. For example Figure 4 the first specific wireless transmission mode diagram shown in, if the signal acquisition end is provided with a single head amplifier and the device is in a wireless mode, that is, the signal acquisition end can transmit signals through a single wireless transmission module when transmitting signals, at this time, the signal processing end can only have a single wireless receiving module responsible for receiving neural signals, and the single wireless receiving module is connected with a single wired receiving module, which is suitable for a single subject and a scene with high requirement for the activity freedom of the subject. The subject can freely move within the signal receiving range and will not be bound by the wire, which reduces the loss of experimental equipment to a certain extent, for example, when a mouse is used as a subject, the data acquisition wire is avoided from being bitten. For example Figure 5The second specific wireless transmission mode shown in the schematic diagram is that if the signal acquisition end is configured with multiple head-mounted amplifiers and the device is in a wireless mode, that is, the signal acquisition end can transmit signals through multiple wireless transmission modules during signal transmission, at this time, the signal processing end can have multiple wireless receiving modules responsible for receiving neural signals, and the multiple wireless receiving modules are connected with multiple wired receiving modules, which is suitable for the scene where multiple subjects perform experiments at the same time, and the wireless receiving signal mode is adopted to avoid the situation that multiple data transmission lines are entangled with each other during the experiment, so that multiple subjects can freely move, and the accuracy of the signal collected by the device will not be reduced, and each receiving module corresponds to a head-mounted amplifier, which expands the number of animals that can be simultaneously experimented.

[0065] When the target transmission mode is a mixed mode of wired transmission and wireless transmission, that is, both wireless transmission and wired transmission are performed, part of the wireless receiving modules are determined as target wireless receiving modules, the wired receiving modules corresponding to the target wireless receiving modules are determined as first target wired receiving modules, and the wired receiving modules other than the first target wired receiving modules are determined as second target wired receiving modules, and the target wireless receiving modules are connected with the first target wired receiving modules. For example Figure 6 A specific mixed transmission mode shown in the schematic diagram is that the signal acquisition end is configured with multiple head-mounted amplifiers, and the device is in a mixed mode, at this time, both wired and wireless signals can be transmitted, specifically, there are three head-mounted amplifiers, among which the neural signals collected by two head-mounted amplifiers are transmitted to the signal processing end through the wireless mode, that is, the first wireless transmission module of the signal acquisition end transmits the neural signals to the first wireless receiving module of the signal processing end, and the second wireless transmission module of the signal acquisition end transmits the neural signals to the second wireless receiving module of the signal processing end, and the neural signals collected by one head-mounted amplifier are transmitted to the signal processing end through the wired mode, that is, the wired transmission module of the signal acquisition end is connected with the wired receiving module of the signal processing end through the HDMI line, and then transmits the neural signals to the signal processing end, so that the device has the advantages of both wired and wireless modes at this time.

[0066] Step S13: If the target receiving module includes the wireless receiving module, the first current neural signal transmitted by the signal acquisition end is received through the wireless receiving module, and the first current neural signal is data frame supplemented to obtain a supplemented neural signal, and the target neural signal is obtained based on the supplemented neural signal.

[0067] In this embodiment, the signal acquisition end includes multiple wireless transmission modules. It can be understood that the signal acquisition end can include multiple wireless transmission modules, and because there is a corresponding relationship between the wireless transmission module and the target receiving module, the number of wireless transmission modules is the same as the number of wireless receiving modules included in the target receiving module.

[0068] In the embodiment, the first current neural signal transmitted by the signal collection end through the wireless receiving module includes: determining a target wireless receiving module from each wireless receiving module; receiving the first current neural signal transmitted by a target wireless transmitting module through the target wireless receiving module; wherein the target wireless transmitting module is a wireless transmitting module in the signal collection end corresponding to the target wireless receiving module.

[0069] If the target receiving module includes a wireless receiving module, it means that the transmission mode includes a wireless transmission mode, that is, it can be a wireless transmission single mode or a hybrid mode, but regardless of which transmission mode, wireless transmission is required, and signal reception is required through a wireless receiving module. For example, a total of 4 wireless receiving modules are included, but only 2 of them are target wireless receiving modules, that is, only 2 of them need to be used for wireless reception, so only these two are determined as target wireless receiving modules. Similarly, if all 4 wireless receiving modules are target wireless receiving modules, signal reception needs to be performed through all 4 wireless receiving modules. After determining the target wireless receiving module, the first current neural signal transmitted by the target wireless transmitting module is received through the target wireless receiving module. It can be understood that the target wireless transmitting module is a wireless transmitting module in the signal collection end corresponding to the target wireless receiving module. Among them, the target wireless transmitting module can be first determined in the signal collection end, and then the target wireless receiving module corresponding to the target wireless transmitting module is determined from the signal processing end. It can also be that the target wireless receiving module of the signal processing end is first determined, and then the target wireless transmitting module of the signal collection end is determined, that is, the target wireless transmitting module and the target wireless receiving module are corresponding.

[0070] In the embodiment, the target wireless receiving module is determined from each wireless receiving module, including: if the target transmission mode is the wireless transmission single mode, each wireless receiving module is determined as a target wireless receiving module, a first target wired receiving module corresponding to the target wireless receiving module is determined from each wired receiving module, and the target wireless receiving module is controlled to be connected with the first target wired receiving module; if the target transmission mode is the hybrid mode, part of the wireless receiving modules are determined as target wireless receiving modules, the wired receiving modules corresponding to the target wireless receiving modules are determined as first target wired receiving modules, and the wired receiving modules other than the first target wired receiving modules in each wired receiving module are determined as second target wired receiving modules, and the target wireless receiving module is controlled to be connected with the first target wired receiving module.

[0071] If the target receiving module includes a wireless receiving module, it means that the target transmission mode is wireless transmission single mode or mixed mode. When the target transmission mode is wireless transmission single mode, and in order to achieve high-throughput signal transmission, each wireless receiving module is determined as a target wireless receiving module, a first target wired receiving module corresponding to the target wireless receiving module is determined from each wired receiving module, and the target wireless receiving module is controlled to be connected with the first target wired receiving module. For example, the signal processing end has a total of 4 wireless receiving modules (i.e. wireless receiving module A, wireless receiving module B, wireless receiving module C, wireless receiving module D), 4 wired receiving modules (wired receiving module a, wired receiving module b, wired receiving module c, wired receiving module d), the wireless receiving module A, the wireless receiving module B, the wireless receiving module C, and the wireless receiving module D are all determined as target wireless receiving modules, the wired receiving module a, the wired receiving module b, the wired receiving module c, and the wired receiving module d are all determined as first target wired receiving modules, and then the wireless receiving module A is controlled to be connected with the wired receiving module a, the wireless receiving module B is controlled to be connected with the wired receiving module b, the wireless receiving module C is controlled to be connected with the wired receiving module c, and the wireless receiving module D is controlled to be connected with the wired receiving module d. When the target transmission mode is mixed mode, part of the wireless receiving modules are determined as target wireless receiving modules, the wired receiving modules corresponding to the target wireless receiving modules are determined as first target wired receiving modules, the wired receiving modules other than the first target wired receiving modules in each wired receiving module are determined as second target wired receiving modules, and the target wireless receiving modules are controlled to be connected with the first target wired receiving modules. For example, the signal processing end has a total of 4 wireless receiving modules (i.e. wireless receiving module A, wireless receiving module B, wireless receiving module C, wireless receiving module D), 4 wired receiving modules (wired receiving module a, wired receiving module b, wired receiving module c, wired receiving module d), the wireless receiving module A and the wireless receiving module B in the wireless receiving modules are determined as target wireless receiving modules, the wired receiving module a and the wired receiving module b are determined as first target wired receiving modules, and the remaining wired receiving module c and wired receiving module d are determined as second target wired receiving modules, and the wireless receiving module A is controlled to be connected with the wired receiving module a and the wireless receiving module B is controlled to be connected with the wired receiving module b.

[0072] It can be understood that, in the process of determining the target wireless receiving module from the wireless receiving modules, when the target transmission mode is the wireless transmission single mode, only part of the wireless receiving modules can be determined as the target wireless receiving module, and then the first target wired receiving module corresponding to the target wireless receiving module is determined from the wired receiving modules, and the target wireless receiving module and the first target wired receiving module are connected, but the remaining wired receiving modules do not participate in the signal transmission. When the target transmission mode is the mixed mode, after determining that the wired receiving module corresponding to the target wireless receiving module is determined as the first target wired receiving module, part of the wired receiving modules in the wired receiving modules except the first target wired receiving module can be selected to determine as the second target wired receiving module, that is, the wired receiving modules in the wired receiving modules except the first target wired receiving module and the second target wired receiving module do not participate in the signal transmission.

[0073] In this way, according to various signal transmission scenarios, appropriate target wireless receiving modules and target wired receiving modules can be selected, and the application scenarios are more flexible and more diverse.

[0074] In the embodiment, the first current neural signal is an encoded neural signal transmitted by the wireless transmitting module based on the frequency division multiplexing mechanism, and the encoded neural signal is a signal obtained by encoding the current original neural signal by the wireless transmitting module.

[0075] In the process of transmitting the signal by the signal acquisition end through the wireless transmitting module, the current original neural signal of the subject is first acquired, and then the digitized current original neural signal is encoded to obtain an encoded neural signal, and the encoded neural signal is transmitted to the wireless receiving module of the signal processing end based on the frequency division multiplexing mechanism, that is, the first current neural signal received by the wireless receiving signal is the encoded neural signal. Among them, the signal acquisition end specifically Manchester encodes the digitized current original neural signal, so that the signal quality can be determined, but the data rate of the encoded neural signal is reduced to half of the original, and in order to prevent signal aliasing, the signal acquisition end uses the frequency division multiplexing technology to send the wireless signal.

[0076] Manchester coding uses the transition of the level to represent the binary information to be transmitted, and in the case of no level transition in a long period of time, any binary sequence can be encoded, and the bit error caused by low-frequency direct current drift in the low-pass analog circuit and the loss of the synchronous clock signal in this case are prevented.

[0077] In this embodiment, the data padding on the first current neural signal to obtain the padded neural signal comprises: frequency band separation on the first current neural signal to obtain each single-channel neural signal; decoding on each single-channel neural signal to obtain decoded neural signals; and data padding on the decoded neural signals to obtain the padded neural signals.

[0078] It can be understood that, because the first current neural signal is the encoded neural signal transmitted by the wireless transmission module based on the frequency division multiplexing mechanism, after the wireless receiving module receives the first current neural signal, the first current neural signal needs to be frequency band separated to obtain each single-channel neural signal, i.e., the data signal before frequency division multiplexing is recovered, and then each single-channel neural signal is decoded to obtain decoded neural signals, and the signals are adaptively data padded to ensure that the data rate received by the wired receiving module and the data rate received by the wired transmission single-mode are consistent, and the data processing time of the signal acquisition processing device is not affected.

[0079] In this embodiment, the target neural signal is obtained based on the padded neural signal, comprising: receiving the padded neural signal sent by the target wireless receiving module through the first target wired receiving module; wherein the first target wired receiving module is a wired receiving module corresponding to the target wireless receiving module; and obtaining the target neural signal based on the padded neural signal.

[0080] The wireless receiving module sends the finally obtained padded neural signal to the first target wired receiving module, i.e., to the wired receiving module corresponding to the target wireless receiving module, so that the first target wired receiving module receives the padded neural signal sent by the target wireless receiving module, and obtains the target neural signal based on the padded neural signal.

[0081] Step S14: If the wired receiving module is included in the target receiving module, receiving the second current neural signal transmitted by the signal acquisition end through the wired receiving module, and obtaining the target neural signal based on the second current neural signal.

[0082] It can be understood that if the target receiving module includes a wired receiving module, that is, if there is a wired receiving module involved in the transmission of the signal, the target transmission mode is a wired transmission single mode or a mixed mode. When it is a wired transmission single mode, there is no wireless receiving module involved in the transmission of the signal, the wireless receiving module is disconnected with the wired receiving module, and the wired sending module of the signal acquisition end is connected with the wired receiving module of the signal processing end through the HDMI line, the length of the HDMI line can be 1.5 meters, and the wired receiving module receives the second current neural signal transmitted by the signal acquisition end, at this time, the number of wired receiving modules responsible for receiving the second current neural signal transmitted by the signal acquisition end can be determined according to the specific scene, that is, all wired receiving modules can transmit signals, or part of the wired receiving modules can transmit signals, and then the target neural signal is obtained based on the second current neural signal; when the target transmission mode is a mixed mode, it can be understood that the wired receiving module can be divided into three categories at this time, the first is the first target wired receiving module, that is, this wired receiving module needs to be connected with the target wireless receiving module, and is responsible for receiving the frame-added neural signal transmitted by the target wireless receiving module, the second is the second target wired receiving module, that is, this wired receiving module does not need to be connected with the target wireless receiving module, but needs to be connected with the wired sending module of the signal acquisition end, that is, to ensure that the wired sending module of the signal acquisition end is connected with the wired receiving module of the signal processing end through the HDMI line, and is responsible for receiving the second current neural signal transmitted by the signal acquisition end, and the third is a wired receiving module that does not participate in the transmission of the current neural signal at all, or a standby receiving module, that is, at this time, it does not need to be connected with the signal acquisition end and the wireless receiving module, only when the role of the standby receiving module is converted into the role of the first target wired receiving module or the second target wired receiving module, it will participate in the transmission of the neural signal.

[0083] In the embodiment, the signal processing end further includes a field programmable logic gate array; the field programmable logic gate array is used to convert the second current neural signal or the frame-added neural signal into a target neural signal, and the target neural signal is a single-ended signal.

[0084] The signal processing end further comprises a field programmable logic gate array (FPGA) and a USB chip, the second current neural signal and the neural signal after frame filling are initial differential signals, and a specific type of the initial differential signal is LVDS (Voltage Differential Signaling), that is, the content of the transmission is neural data, and the field programmable logic gate array is responsible for converting the initial differential signal into a single-ended signal. Since the second current neural signal and the neural signal after frame filling come from different ports and there may be a case that multiple ports simultaneously transmit the signals to the field programmable logic gate array at the same time, the field programmable logic gate array needs to separate the signals and then transmit the single-ended signals to the USB chip. Specifically, the signals transmitted by different wired receiving ports are input to different pins of the field programmable logic gate array, the field programmable logic gate array is provided with 8 true differential pins, and the four differential signals transmitted by the four ports are received by pairing the true differential pins. The signals processed by the field programmable logic gate array are transmitted to corresponding pins of the USB chip.

[0085] Step S15: transmitting the target neural signal to the host computer.

[0086] In the embodiment, the signal processing end further comprises a USB chip; wherein the USB chip is used for transmitting the target neural signal to the host computer.

[0087] The signal processing end further comprises a field programmable logic gate array and a USB chip, and the USB chip is a bridge connecting the FPGA and the host computer, that is, the USB chip is a high-speed data channel between the two, and a Type-c port of the USB chip transmits the target neural signal to the host computer, and the host computer is specifically a computer, and the USB chip can be specifically a CYUSB3014 chip. Specifically, in order to achieve better data transmission, the USB chip can further process the target neural signal, that is, the USB chip is used for converting the target neural signal into a target differential signal and transmitting the target differential signal to the host computer. The process of converting the target neural signal into a target differential signal by the USB chip is that the target neural signal is packaged into a USB3.0 protocol data packet, and then the USB standard interface is used to transmit the target neural signal in the form of a differential signal to the computer, so that the computer can recognize the target neural signal.

[0088] The shell of the signal processing end can also be provided with a screen and a knob of a preset size. The knob can control the screen. The signal processing end also includes LED (Light-Emitting Diode Light) lamps corresponding to the wired receiving modules. When the HDMI line is connected to the wired receiving module, the corresponding LED lamp will emit blue light. When any wired receiving module receives the second current neural signal or the neural signal after frame interpolation, the LED lamp corresponding to the wired receiving module will emit red light all the time. That is, the wired receiving module corresponding to the LED lamp emitting red light all the time currently receives the second current neural signal or the neural signal after frame interpolation. Therefore, the user can more clearly and intuitively understand the current signal transmission situation.

[0089] The embodiment can improve the signal acquisition efficiency. The high-throughput design can simultaneously acquire signals of multiple subjects. The neural signals of multiple channels can be efficiently transmitted in parallel, which improves the experimental efficiency and reduces the purchase cost of experimental equipment. The wired transmission mode and the wireless transmission mode can be quickly switched. The wireless receiving module is added to the signal processing end. The signal transmission mode can be changed from the wired mode to the wireless mode. For the signal acquisition end, only a wireless transmitting module needs to be added. For the signal processing end, only a wireless receiving module needs to be added. The data processing time of the signal processing end is consistent with that in the wired transmission mode. In addition, the freedom and comfort of the subject are ensured. The subject can freely move within the signal receiving range. In the wireless transmission mode, the lead is not pulled, and the freedom and comfort of the subject in the experiment are higher. The embodiment has universal applicability and supports flexible configuration, and is suitable for various brain-computer interface application scenarios.

[0090] The application has the advantages that: the signal processing end includes a wired receiving module and a wireless receiving module; the method includes: determining a target transmission mode from each preset neural signal transmission mode; wherein each preset neural signal transmission mode includes a wired transmission single mode, a wireless transmission single mode, and a mixed mode of wired transmission and wireless transmission; determining a target receiving module from the wired receiving module and the wireless receiving module based on the target transmission mode; if the target receiving module includes the wireless receiving module, receiving a first current neural signal transmitted by a signal acquisition end through the wireless receiving module, performing data frame supplementation on the first current neural signal to obtain a supplemented neural signal, and obtaining a target neural signal based on the supplemented neural signal; if the target receiving module includes the wired receiving module, receiving a second current neural signal transmitted by the signal acquisition end through the wired receiving module, and obtaining a target neural signal based on the second current neural signal; and transmitting the target neural signal to an upper computer. It can be seen that the application can realize flexible switching of multi-modal transmission modes to adapt to different experimental scenes, determine a target transmission mode and match a corresponding receiving module, use a wired receiving module to ensure signal stability and low latency in a wired transmission single mode, and be suitable for scenes where the activity freedom of a subject is not high, use a wireless receiving module in combination with data frame supplementation in a wireless transmission single mode and a mixed mode to ensure that the data rate during wireless transmission is consistent with that during wired mode, avoid differences in data processing time sequence caused by coding, and at the same time, release the subject from the restraint of a wire, so that the application is suitable for scenes where the subject needs to move freely or needs to be isolated, and the mixed mode can have the advantages of wired and wireless transmission, and expand the applicability of the system in complex experimental environments.

[0091] The following is an example of a neural signal transmission mode Figure 7The transmission between the signal acquisition end and the signal processing end is shown in the specific signal collection end and the signal processing end. The transmission mode between the signal acquisition end and the signal processing end includes a single mode of wired transmission, a single mode of wireless transmission and a mixed mode of wired transmission and wireless transmission. In the single mode of wired transmission, the wired sending module of the signal acquisition end and the wired receiving module of the signal processing end are connected through the HDMI line, that is, the HDMI line is used as the loop path of the clock signal. When the head-mounted amplifier of the signal acquisition end collects the neural signal of the subject, the wired sending module transmits the neural signal to the wired receiving module through the HDMI line. In the single mode of wireless transmission, the wired sending module of the signal acquisition end is connected with the detachable wireless transmitting module, and the wired receiving module of the signal processing end is connected with the detachable wireless receiving module. When the head-mounted amplifier of the signal acquisition end collects the neural signal of the subject, the wireless transmitting module encodes the neural signal and then transmits it to the wireless receiving module based on the frequency division multiplexing mechanism. The wireless receiving module separates the received neural signal by frequency, decodes it, and frames the data to obtain the framed neural signal, and then transmits the framed neural signal to the wired receiving module connected with the wireless receiving module. In the mixed mode, part of the wired sending module of the signal acquisition end is connected with the detachable wireless transmitting module, and part of the wired receiving module of the signal processing end is connected with the detachable wireless receiving module. The wired sending module of the signal acquisition end that is not connected with the wireless transmitting module is connected with the wired receiving module of the signal processing end that is not connected with the wireless receiving module through the HDMI line. In this way, when one or more head-mounted amplifiers of the signal acquisition end collect the neural signal of the subject, part of the neural signal of the head-mounted amplifier is transmitted to the signal processing end through the wireless transmission mode, and the other part of the neural signal of the head-mounted amplifier is transmitted to the signal processing end through the wired mode. In this way, the wired and wireless mixed transmission of the neural signal is realized. The signal processing end also includes a computer interface, that is, an upper computer interface. The signal processing end converts the neural signal received by the wired receiving module into a target differential signal, and then transmits the target differential signal to the computer through the computer interface, so that the computer can identify and process the target differential signal.

[0092] Specifically, the signal processing end includes four wired receiving modules and four wireless receiving modules, and each receiving module can receive signals of 128 channels, and the wireless bandwidth exceeds 200 Mbps, if all the receiving modules participate in signal transmission at the same time, the signal processing end can simultaneously transmit signals of 512 channels, it can be seen that the signal processing end supports high-throughput signal transmission, in this way, whether to increase the wireless transmission module in the neural signal transmission process can be selected to realize wired or wireless signal transmission mode, the wireless receiving module in the wireless transmission module can perform data frame supplementation according to different received data rates, so as to realize the same data transmission effect as the wired transmission mode, the signal processing end can process the digital signal transmitted by the signal acquisition end into a signal that can be recognized by a computer, and when multiple ports are used at the same time, high-throughput signal acquisition is realized, the signal acquisition efficiency is improved, and the experimental scene is expanded.

[0094] A transmission mode determination module 11 is configured to determine a target transmission mode from a plurality of preset neural signal transmission modes; wherein each of the preset neural signal transmission modes includes a wired transmission single mode, a wireless transmission single mode, and a mixed mode of wired transmission and wireless transmission.

[0095] A receiving module determination module 12 is configured to determine a target receiving module from the wired receiving module and the wireless receiving module based on the target transmission mode.

[0096] A first receiving module 13 is configured to receive a first current neural signal transmitted by a signal acquisition end through the wireless receiving module if the target receiving module includes the wireless receiving module, and perform data frame supplementation on the first current neural signal to obtain a supplemented neural signal, and obtain a target neural signal based on the supplemented neural signal.

[0097] A second receiving module 14 is configured to receive a second current neural signal transmitted by a signal acquisition end through the wired receiving module if the target receiving module includes the wired receiving module, and obtain a target neural signal based on the second current neural signal.

[0098] A transmission module 15 is configured to transmit the target neural signal to an upper computer.
