DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] As a core technology for exploring the frontiers of brain science and promoting human-computer interaction, brain-computer interface (BCI) technology has become a key element in global technological competition. Its development has made the leap from proof-of-concept to practical application, with breakthroughs in technology from non-invasive to invasive, signal transmission from low-throughput to high-throughput, and system architecture from wired to wireless interaction. Non-invasive BCI devices record EEG activity using high-density electrode arrays on the scalp surface, but the signals suffer a significant loss of detail and spatial resolution after passing through the biological tissue barrier. Invasive BCIs surgically implant electrodes into the cortex and utilize a headstage to acquire neural signals. These devices can accurately detect the firing of single or multiple neurons, becoming a key trend in BCI development. For computers to recognize the EEG signals captured by the headstage, equally high-throughput signal acquisition and processing devices are required to process these signals and meet diverse application scenarios.

[0019] To this end, this application provides a neural signal transmission solution to improve the flexibility of neural signal transmission and minimize the impact on transmission efficiency.

[0020] See also Figure 1 As shown, an embodiment of the present application discloses a neural signal transmission method, which is applied to a signal processing end, wherein the signal processing end includes a wired receiving module and a wireless receiving module; the method includes: Step S11: Determine 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.

[0021] In this embodiment, the number of the wired receiving modules and the number of the wireless receiving modules are both plural, and the number of the wireless receiving modules is not greater than the number of the wired receiving modules.

[0022] Specifically, the signal processing end includes multiple wired receiving modules and wireless receiving modules, and the number of wireless receiving modules is not greater than the number of 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 to say, when the target transmission mode is the wired transmission single mode, the wireless receiving module is controlled to be disconnected from the wired receiving module. When the target transmission mode is the wireless transmission single mode, all wireless receiving modules are controlled to be connected to the wired receiving module. It can be understood that a wireless receiving port is a single port. The receiving module is connected to a wired receiving module, rather than multiple wireless receiving modules being connected to the same wired receiving module. When the target transmission mode is a mixed mode of wired transmission and wireless transmission, some wireless receiving modules are controlled to be connected to the wired receiving module, and different wireless receiving modules are connected to different wired receiving modules. It can be seen that the wired receiving port ensures the normal use of the basic functions of the device and can stably collect signals. The wireless receiving module increases the function of the device without affecting the original function, expands the application scenarios, ensures that the subjects can move freely, and the design of the signal receiving method is suitable for a variety of application scenarios.

[0023] In a specific case, the signal processing end includes 4 wired receiving modules, that is, 4 wired receiving ports, each wired receiving port can receive 128 channels of signals. When all ports are used at the same time, the device collects a total of 512 channels of signals, and the wireless bandwidth exceeds 200Mbps. That is to say, if it is a single wired transmission mode, the neural signals are received through 4 wired receiving modules. If it is a single wireless transmission mode, the 4 wired receiving modules are controlled to be connected to the 4 wireless receiving modules, so that the neural signals can be received through the 4 wireless receiving modules, and then the received neural signals are forwarded to the 4 wired receiving modules. If it is a mixed mode of wired transmission and wireless transmission, some wired receiving modules are controlled to be connected to some wireless receiving modules, so that the neural signals are received through the wired receiving modules that are not connected to the wireless receiving modules, and also through the wireless receiving modules, and then the neural signals received by the wireless receiving modules are forwarded to the wired receiving modules. Therefore, when transmitting neural signals, no matter which mode is used, 512 channels of signals can be selected for transmission, so high-throughput signal transmission can be achieved.

[0024] In this embodiment, each preset neural signal transmission mode includes a single wired transmission mode, a single wireless transmission mode, and a mixed mode of wired and wireless transmission. That is to say, this embodiment supports wired transmission, wireless transmission, and a mixed mode of wired and wireless transmission of neural signals, making its application scenarios more flexible.

[0025] It should be noted that this embodiment transmits the subject's neural signal from the signal acquisition end to the signal processing end, and then transmits it from the signal processing end to the host computer, which involves the transmission of neural signals, and in order to carry out signal transmission more reasonably, some processing of the neural signals is also required.

[0026] Step S12: determining a target receiving module from the wired receiving module and the wireless receiving module based on the target transmission mode.

[0027] In this embodiment, the target receiving module is determined from the wired receiving module and the wireless receiving module based on the target transmission mode, including: if the target transmission mode is the wired transmission single mode, each of the wired receiving modules is determined as a target receiving module, and the wireless receiving module is controlled to disconnect from the wired receiving module.

[0028] The preset neural signal transmission modes include a single wired transmission mode, a single wireless transmission mode, and a mixed mode of wired and wireless transmission. That is to say, according to the requirements of different scenarios, a suitable target transmission mode can be selected.

[0029] When the target transmission mode is a wired transmission single mode, that is, only a wired receiving module is needed to transmit neural signals, then all wired receiving modules can be determined as target receiving modules. At this time, it is necessary to control the wireless receiving module to disconnect from the wired receiving module. Furthermore, it is also necessary to control the wired receiving module to connect to the wired sending module of the signal acquisition end through an HDMI cable (High Definition Multimedia Interface Cable) so that the current neural signal transmitted by the signal acquisition end can be received through the wired receiving module. For example Figure 2 The first specific wired transmission mode schematic diagram and Figure 3 As shown in the second specific wired transmission mode diagram, if the signal acquisition end is only equipped with a single head amplifier, that is to say, when the signal acquisition end is transmitting the signal, only a single wired sending port can be used to send the signal. At this time, the signal processing end also has only a single wired receiving module connected to the wired sending module. This situation is suitable for scenarios with a single subject and low requirements for the subject's freedom of movement. The wired mode has high signal anti-interference ability, stability and low latency; if the signal acquisition end is equipped with multiple head amplifiers, that is to say, when the signal acquisition end is transmitting the signal, multiple wired sending ports can be used to send the signal. At this time, the signal processing end can also have multiple wired receiving modules connected to multiple wired sending modules. It is suitable for experimental scenarios with multiple subjects and low requirements for the subject's freedom of movement. It can collect EEG signals of multiple subjects at the same time to improve experimental efficiency.

[0030] When the target transmission mode is wireless transmission mode only, that is, only wireless transmission is performed, then all wireless receiving modules can be determined as target receiving modules. At this time, it is necessary to control the connection between the wireless receiving modules and the wired receiving modules. Figure 4 The first specific wireless transmission mode diagram shown is that if the signal acquisition end is equipped with a single head amplifier and the device is in wireless mode, then that is to say, when the signal acquisition end is transmitting signals, it can transmit signals through a single wireless transmission module. At this time, the signal processing end can only have a single wireless receiving module responsible for receiving neural signals, and this single wireless receiving module is connected to a single wired receiving module. It is suitable for a single subject and has high requirements for the subject's freedom of movement. The subject can move freely within the signal receiving range and will not be bound by the wires, which reduces the loss of experimental equipment to a certain extent. For example, when mice are used as subjects, the data acquisition wires are prevented from being bitten. For example Figure 5The second specific wireless transmission mode diagram shown is that if the signal acquisition end is equipped with multiple head amplifiers and the device is in wireless mode, then that is to say, when the signal acquisition end is transmitting signals, it can transmit signals through multiple wireless sending modules. At this time, the signal processing end can have multiple wireless receiving modules responsible for receiving neural signals, and these multiple wireless receiving modules are connected to multiple wired receiving modules. It is suitable for scenarios where multiple subjects are conducting experiments at the same time. The wireless signal receiving mode avoids the situation where multiple data transmission lines are entangled with each other during the experiment, ensuring that multiple subjects can move freely and the accuracy of the signal acquisition by the device will not be reduced. Each receiving module corresponds to a head amplifier, which expands the number of animals that can be experimented synchronously.

[0031] 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, then some 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 among the wired receiving modules are determined as second target wired receiving modules, and the target wireless receiving modules are controlled to connect to the first target wired receiving modules. For example Figure 6 A specific hybrid transmission mode schematic diagram is shown, in which the signal acquisition end is equipped with multiple head amplifiers, and the device is in hybrid mode, at which time wired and wireless signals can be transmitted simultaneously. Specifically, there are 3 head amplifiers, of which the neural signals collected by 2 head amplifiers are transmitted to the signal processing end through wireless mode, that is, the first wireless transmitting module of the signal acquisition end transmits the neural signal to the first wireless receiving module of the signal processing end, and the second wireless transmitting module of the signal acquisition end transmits the neural signal to the second wireless receiving module of the signal processing end. The neural signal collected by one of the head amplifiers is transmitted to the signal processing end through wired mode, that is, the wired transmitting module of the signal acquisition end is connected to the wired receiving module of the signal processing end through an HDMI cable, and then the neural signal is transmitted to the signal processing end. It can be seen that the device now has the advantages of both wired and wireless modes.

[0032] 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 frame-interpolated to obtain a frame-interpolated neural signal, and the target neural signal is obtained based on the frame-interpolated neural signal.

[0033] In this embodiment, the signal acquisition terminal includes multiple wireless transmission modules. It is understandable that the signal acquisition terminal can include multiple wireless transmission modules. Because there is a corresponding relationship between the wireless transmission modules and the target receiving modules, the number of wireless transmission modules is the same as the number of wireless receiving modules included in the target receiving modules.

[0034] In this embodiment, the receiving of the first current neural signal transmitted by the signal acquisition end through the wireless receiving module includes: determining a target wireless receiving module from each of the wireless receiving modules; receiving the first current neural signal transmitted by the target wireless transmitting module through the target wireless receiving module; wherein, the target wireless transmitting module is a wireless transmitting module in the signal acquisition end corresponding to the target wireless receiving module.

[0035] If the target receiving module includes a wireless receiving module, it means that the transmission mode includes a wireless transmission mode, that is, it may be a single wireless transmission mode or a mixed mode. However, no matter which transmission mode is used, wireless transmission is required, and signals need to be received through the wireless receiving module. For example, there are a total of 4 wireless receiving modules, 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, signals need to be received through these 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 the wireless transmitting module corresponding to the target wireless receiving module in the signal acquisition end. Among them, the target wireless transmission module can be first determined in the signal acquisition end, and then the target wireless receiving module corresponding to the target wireless transmission module can be 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 transmission module of the signal acquisition end is determined. In other words, the target wireless transmission module and the target wireless receiving module correspond to each other.

[0036] In this embodiment, the determining of the target wireless receiving module from each of the wireless receiving modules includes: if the target transmission mode is the wireless transmission single mode, determining each of the wireless receiving modules as the target wireless receiving module, determining a first target wired receiving module corresponding to the target wireless receiving module from each of the wired receiving modules, and controlling the target wireless receiving module to be connected to the first target wired receiving module; if the target transmission mode is the mixed mode, determining some of the wireless receiving modules as the target wireless receiving modules, determining the wired receiving module corresponding to the target wireless receiving module as the first target wired receiving module, determining the wired receiving modules other than the first target wired receiving module in each of the wired receiving modules as the second target wired receiving module, and controlling the target wireless receiving module to be connected to the first target wired receiving module.

[0037] If the target receiving module includes a wireless receiving module, then it means that the target transmission mode is a wireless transmission single mode or a mixed mode. When the target transmission mode is a 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, and 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 connect to 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 D), and 4 wireless receiving modules (wired receiving module B, wireless receiving module C, wireless receiving module D). b, wired receiving module c, wired receiving module d), then 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, and 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 to the wired receiving module a, the wireless receiving module B is connected to the wired receiving module b, the wireless receiving module C is connected to the wired receiving module c, and the wireless receiving module D is connected to the wired receiving module d. When the target transmission mode is a hybrid mode, some 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 module among the wired receiving modules are determined as second target wired receiving modules. The target wireless receiving modules are controlled to be connected to the first target wired receiving module. For example, if the signal processing end has a total of four wireless receiving modules (i.e., wireless receiving module A, wireless receiving module B, wireless receiving module C, and wireless receiving module D) and four wired receiving modules (wired receiving module a, wired receiving module b, wired receiving module c, and wired receiving module d), wireless receiving module A and wireless receiving module B among the wireless receiving modules are determined as target wireless receiving modules, wired receiving module a and 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. The wireless receiving module A is controlled to be connected to the wired receiving module a, and the wireless receiving module B is controlled to be connected to the wired receiving module b.

[0038] It is understandable that, in the process of determining the target wireless receiving module from each wireless receiving module, when the target transmission mode is wireless transmission single mode, only some of the wireless receiving modules can be determined as the target wireless receiving modules, and then 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 also controlled to be connected to the first target wired receiving module, but the remaining wired receiving modules do not participate in signal transmission. When the target transmission mode is a 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, some of the wired receiving modules other than the first target wired receiving module in each wired receiving module can be selected as the second target wired receiving modules, that is, the wired receiving modules other than the first target wired receiving module and the second target wired receiving module in the wired receiving modules do not participate in signal transmission.

[0039] In this way, appropriate target wireless receiving modules and target wired receiving modules can be selected according to various signal transmission scenarios, making application scenarios more flexible and diverse.

[0040] In this embodiment, the first current neural signal is the neural signal after being encoded and transmitted by the wireless transmission module based on a frequency division multiplexing mechanism, and the encoded neural signal is the signal obtained by encoding the current original neural signal by the wireless transmission module.

[0041] When the signal acquisition end transmits the signal through the wireless transmission module, it first collects the subject's current original neural signal, then encodes the digitized current original neural signal to obtain the encoded neural signal, and then transmits the encoded neural signal to the wireless receiving module of the signal processing end based on the frequency division multiplexing mechanism. In other words, the first current neural signal received by the wireless receiving signal is the encoded neural signal. Among them, the signal acquisition end specifically performs Manchester encoding on the digitized current original neural signal. In this way, the signal quality can be determined. However, since the data rate of the encoded neural signal is reduced to half of the original rate, and in order to prevent signal aliasing, the signal acquisition end uses frequency division multiplexing technology to send wireless signals.

[0042] Manchester coding uses level jumps to represent the binary information to be transmitted. Even if there are no level jumps for a long period of time, it can still encode any binary sequence and prevent bit errors caused by low-frequency DC drift in low-pass analog circuits and the loss of synchronous clock signals in this case.

[0043] In this embodiment, the data frame complementing of the first current neural signal to obtain the frame-complemented neural signal includes: frequency band separation of the first current neural signal to obtain each single-channel neural signal; decoding each of the single-channel neural signals to obtain a decoded neural signal; and data frame complementing of the decoded neural signal to obtain a frame-complemented neural signal.

[0044] It can be understood that because the first current neural signal is the encoded neural signal transmitted by the wireless transmitting module based on the frequency division multiplexing mechanism, after the wireless receiving module receives the first current neural signal, it is also necessary to perform frequency band separation on the first current neural signal to obtain each single-channel neural signal, that is, to restore the data signal before frequency division multiplexing, and then decode each single-channel neural signal to obtain the decoded neural signal, and adaptively perform data interpolation on the signal to ensure that the data rate received by the wired receiving module is consistent with the data rate received by the wired transmission single mode, and will not affect the data processing time of the signal acquisition and processing device.

[0045] In this embodiment, the target neural signal is obtained based on the frame-padded neural signal, including: receiving the frame-padded neural signal sent by the target wireless receiving module through a 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 frame-padded neural signal.

[0046] The wireless receiving module sends the final frame-padded neural signal to the first target wired receiving module, that is, to the wired receiving module corresponding to the target wireless receiving module, so that the first target wired receiving module receives the frame-padded neural signal sent by the target wireless receiving module and obtains the target neural signal based on the frame-padded neural signal.

[0047] Step S14: If the target receiving module includes the wired receiving module, the second current neural signal transmitted by the signal acquisition end is received through the wired receiving module, and the target neural signal is acquired based on the second current neural signal.

[0048] It can be understood that if the target receiving module includes a wired receiving module, that is, if there is a need for the wired receiving module to participate in the transmission of the signal, then 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 participating in the transmission of the signal, then the wireless receiving module is disconnected from the wired receiving module, and the wired sending module of the signal acquisition end is connected to the wired receiving module of the signal processing end through an HDMI cable. The specific length of the HDMI cable can be 1.5 meters, and the second current neural signal transmitted by the signal acquisition end is received through the wired receiving module. At this time, the number of wired receiving modules responsible for receiving the second current neural signal transmitted by the acquisition end can be determined according to the specific scenario. It can be that all wired receiving modules perform signal transmission, or it can be that some wired receiving modules perform signal transmission. Next, 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. Module, that is, this wired receiving module needs to be connected to the target wireless receiving module, and is responsible for receiving the frame-filled 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 to the target wireless receiving module, but needs to be connected to 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 to the wired receiving module of the signal processing end through the HDMI cable, and is responsible for receiving the second current neural signal transmitted by the signal acquisition end. The third is a wired receiving module that does not participate in the current neural signal transmission at all, or in other words, as a backup receiving module, that is, it does not need to be connected to the signal acquisition end or the wireless receiving module at this time. Only when it is converted from the role of the backup receiving module to the role of the first target wired receiving module or the second target wired receiving module will it participate in the transmission of the neural signal.

[0049] In this embodiment, the signal processing end also 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-filled neural signal into a target neural signal, and the target neural signal is a single-ended signal.

[0050] The signal processing end also includes a field programmable gate array (FPGA) and a USB (Universal Serial Bus) chip. The second current neural signal and the frame-filled neural signal are both initial differential signals. The specific type of the initial differential signal is LVDS (Voltage Differential Signaling), that is, the content transmitted is neural data. The FPGA is responsible for converting the initial differential signal into a single-ended signal. Since the second current neural signal and the frame-filled neural signal come from different ports, and there may be situations where multiple ports transmit signals to the FPGA at the same time, the FPGA needs to separate the signals and then transmit the single-ended signal to the USB chip. Specifically, the signals transmitted by different wired receiving ports are input into different pins of the FPGA. The FPGA has a total of 8 true differential pins, which are paired to receive differential signals transmitted by 4 ports. The signals processed by the FPGA are transmitted to the corresponding pins on the USB chip.

[0051] Step S15: Transmitting the target neural signal to a host computer.

[0052] In this embodiment, the signal processing end further includes a USB chip; wherein the USB chip is used to transmit the target neural signal to a host computer.

[0053] The signal processing end also includes a field programmable logic gate array and a USB chip. The USB chip is a bridge connecting the FPGA and the host computer. That is, the USB chip serves as a high-speed data channel between the two. The Type-C port of the USB chip transmits the target neural signal to the host computer, which is specifically a computer. The USB chip can specifically be a CYUSB3014 chip. Specifically, to achieve better data transmission, the USB chip can also further process the target neural signal. That is, the USB chip is used to convert the target neural signal into a target differential signal and transmit the target differential signal to the host computer. The process of the USB chip converting the target neural signal into a target differential signal is to package the target neural signal into a USB3.0 protocol data packet, and then transmit it to the computer in the form of a differential signal through the USB standard interface, so that it can be recognized by the computer.

[0054] The outer shell of the signal processing end can also be set with a screen and a knob of preset size. The screen can be controlled by rotating the knob. The signal processing end also includes LED (Light-Emitting Diode Light) lights corresponding to each wired receiving module. When the HDMI cable is connected to the wired receiving module, the corresponding LED light will light up blue. When any wired receiving module receives the second current neural signal or the frame-filled neural signal, the corresponding LED light will be constantly red. In other words, the wired receiving module corresponding to the constantly red LED light has currently received the second current neural signal or the frame-filled neural signal, allowing users to understand the current signal transmission situation more clearly and intuitively.

[0055] This embodiment can improve the efficiency of signal acquisition. The high-throughput design can collect signals from multiple subjects at the same time, ensuring that the neural signals of multiple channels can be efficiently transmitted in parallel, improving the efficiency of the experiment and reducing the cost of purchasing experimental equipment. It can also realize rapid switching between wired transmission mode and wireless transmission mode. By adding a wireless receiving module to the signal processing end, the signal transmission mode can be changed from wired mode to wireless mode. For the signal acquisition end, only a new wireless transmitting module needs to be added, and for the signal processing end, only a new wireless receiving module needs to be added. When the wireless transmission mode is implemented, 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 subjects are ensured. The subjects can move freely within the signal receiving range, especially in the wireless transmission mode, avoiding the pulling of wires, and the subjects have higher freedom and comfort in the experiment. It has universal applicability, supports flexible configuration, and is adaptable to various brain-computer interface application scenarios.

[0056] The beneficial effects of the present application are as follows: the signal processing end described in the present application 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, 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 frame-interpolated to obtain a frame-interpolated neural signal, and a target neural signal is obtained based on the frame-interpolated neural signal; if the target receiving module includes the wired receiving module, the second current neural signal transmitted by the signal acquisition end is received through the wired receiving module, and a target neural signal is obtained based on the second current neural signal; and the target neural signal is transmitted to the host computer. It can be seen that the present application can realize flexible switching of multimodal transmission modes to adapt to different experimental scenarios. By determining the target transmission mode and matching the corresponding receiving module, the wired receiving module can be used in the wired transmission single mode to ensure signal stability and low latency, which is suitable for scenarios where the subject's freedom of movement is not required. In the wireless transmission single mode and hybrid mode, the wireless receiving module is combined with data framing to ensure that the data rate during wireless transmission is consistent with the wired mode, avoiding the data processing timing difference caused by encoding, and at the same time releasing the constraints of the wired on the subject. It is suitable for scenarios where the subject needs to move freely or needs to be isolated, and the hybrid mode can have the advantages of both wired and wireless transmission, expanding the applicability of the system in complex experimental environments.

[0057] Below is Figure 7Taking a specific transmission schematic diagram between a signal acquisition end and a signal processing end as an example, the present application is described accordingly. The transmission modes between the signal acquisition end and the signal processing end include a wired transmission single mode, a wireless transmission single mode, and a mixed mode of wired transmission and wireless transmission. In the wired transmission single mode, it is necessary to connect the wired sending module of the signal acquisition end and the wired receiving module of the signal processing end through an HDMI cable, that is, the HDMI cable also serves as a loop path for the clock signal. When the head amplifier of the signal acquisition end collects the neural signal of the subject, it controls the wired sending module to transmit the neural signal to the wired receiving module through the HDMI cable. In the single wireless transmission mode, the wired sending module of the signal acquisition end is connected to the detachable wireless transmitting module, and the wired receiving module of the signal processing end is connected to the detachable wireless receiving module. When the head amplifier of the signal acquisition end collects the neural signal of the subject, the wireless transmitting module is controlled to encode the neural signal and then transmit it to the wireless receiving module based on the frequency division multiplexing mechanism. The wireless receiving module performs frequency band separation, decoding, and data frame filling on the received neural signal to obtain the frame-filled neural signal, and then transmits the frame-filled neural signal to the wired receiving module connected to the wireless receiving module. In hybrid mode, some of the wired transmission modules on the signal acquisition side are connected to the detachable wireless transmission module, and some of the wired receiving modules on the signal processing side are connected to the detachable wireless receiving module. Furthermore, the wired transmission modules on the signal acquisition side that are not connected to the wireless transmission module are connected to the wired receiving modules on the signal processing side that are not connected to the wireless receiving module via HDMI cables. In this way, when one or more head-mounted amplifiers on the signal acquisition side acquire the subject's neural signals, some of the neural signals from the head-mounted amplifiers are transmitted to the signal processing side via wireless transmission, while other neural signals from the head-mounted amplifiers are transmitted to the signal processing side via wired transmission. This achieves hybrid wired and wireless transmission of neural signals. The signal processing side also includes a computer interface, i.e., a host computer interface. After the signal processing side converts the neural signals received by the wired receiving modules into target differential signals, it then uses the computer interface to transmit the target differential signals to the computer, allowing the computer to perform operations such as identification and processing on the target differential signals.

[0058] Specifically, the signal processing end includes 4 wired receiving modules and 4 wireless receiving modules, and each receiving module can receive signals from 128 channels, and the wireless bandwidth exceeds 200Mbps. If all receiving modules participate in signal transmission at the same time, the signal processing end can transmit signals from 512 channels at the same time. It can be seen that the signal processing end supports high-throughput signal transmission. In this way, it is possible to choose whether to add a wireless transmission module during the neural signal transmission process to achieve wired or wireless signal transmission. The wireless receiving module in the wireless transmission module can perform data interpolation according to the different received data rates, thereby achieving the same data transmission effect as the wired transmission mode. The signal processing end can process the digital signal sent by the signal acquisition end into a signal that can be recognized by the computer, and realize high-throughput signal acquisition when multiple ports are used at the same time, thereby improving signal acquisition efficiency and expanding the experimental scenario.
