Specifically, it relates to a method and device for acquiring multiple types of physiological electrical signals with a portable multi-device and multi-electrode configuration. Background Art

[0002] Physiological electrical signals are bioelectrical changes generated during the activity of biological tissues. They are multi-dimensional time series signals of voltage changes obtained through electrode guidance, amplification, recording, and display, and can accurately reflect the state of different biological tissues during movement.

[0003] Existing technologies usually use fixed or desktop devices for physiological electrical signal acquisition. The methods for acquiring physiological electrical signals using existing fixed or desktop devices can usually only acquire a single type of physiological electrical signal or can only obtain physiological electrical signals at one location at a time. They cannot simultaneously acquire physiological electrical signals at different locations or acquire different types of physiological electrical signals corresponding to the same location. It is necessary to repeatedly acquire physiological electrical signals by moving the fixed device and the desktop device, resulting in extremely low efficiency of physiological electrical signal acquisition.

First, multiple flexible electrodes are used to synchronously collect physiological electrical signals at different positions, so as to improve the collection efficiency. Secondly, after different physiological electrical signals are collected by the multiple flexible electrodes, multiple signal collectors are used to synchronously obtain and process the multiple physiological electrical signals of the multiple flexible electrodes, so as to improve the data - processing efficiency of the signal collectors by reducing the amount of data that each signal collector needs to process.

[0118] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0119] Embodiment 1

[0120] When the prior art uses fixed devices and desktop devices to collect physiological electrical signals, it can often only be fixed at one position to collect physiological electrical signals, and the types of collected signals are single. It is impossible to synchronously collect physiological electrical signals of different positions and different types, thereby reducing the efficiency of physiological electrical signal collection.

[0121] In response to this, this embodiment discloses a method for collecting multiple types of physiological electrical signals with a portable multi-machine and multi-electrode, including a collection device with a plurality of signal collectors and a plurality of flexible electrodes; any one of the signal collectors is used to obtain the collection signals of all the flexible electrodes; the plurality of flexible electrodes are used to collect multiple physiological electrical signals under different skin surfaces. Specifically, the process of collecting physiological electrical signals based on the collection device is as Figure 1 shown, specifically, including:

[0122] Step S101: Based on a preset collection requirement, determine the type of physiological electrical signal to be collected by each signal collector.

[0123] Step S102: Configure the signal collection parameters corresponding to each signal collector according to the type of physiological electrical signal to be collected.

[0124] Step S103: Send the signal collection parameters to the corresponding signal collector, so that the signal collector synchronously obtains the collection signals corresponding to the type of physiological electrical signal to be collected from the corresponding flexible electrode according to the signal collection parameters.

[0125] In the embodiments of the present disclosure, in the above acquisition method, first, the flexible electrode can be used to acquire physiological electrical signals at any position, thereby realizing signal acquisition in a distributed area. Further, when the flexible electrode is fixed to the skin surface at the position to be measured, since various types of physiological electrical signals are acquired by the flexible electrode and the physiological electrical signals acquired by the flexible electrode are relatively weak, it is necessary to set up a signal collector to process the physiological electrical signals sent by the flexible electrode, so as to obtain clearer physiological electrical signals subsequently. Specifically, when using the signal collector to process the physiological electrical signals sent by the flexible electrode, in order to improve the efficiency of signal processing, multiple signal collectors in an idle state are selected to perform signal processing simultaneously to improve the efficiency of signal acquisition. Among them, a corresponding type of physiological electrical signal to be acquired is matched for each signal collector performing signal acquisition to improve the accuracy of the signal collector during signal processing.

[0126] In an implementation manner of this embodiment, when using the signal collector to acquire the physiological electrical signals sent by the flexible electrode for processing, it is necessary to ensure that the signal collector is in an idle state, that is, not connected to other flexible electrodes for signals, so as to avoid repeated selection of the signal collector, thereby affecting the acquisition of physiological electrical signals.

[0127] Specifically, when selecting the signal collector for current signal acquisition, that is, when step 101 assigns the type of physiological electrical signal to be acquired to the signal collectors in an idle state, the selection of the signal collector in the idle state can be performed through the following steps, including:

[0128] Step S1011: Obtain the status data corresponding to each signal collector to determine several signal collectors in an idle state.

[0129] Step S1012: Based on the preset acquisition requirements, determine the type of physiological electrical signal to be acquired by each signal collector in an idle state.

[0130] In the above preferred selection scheme, multiple signal collectors in an idle state are selected from multiple signal collectors in an idle state to process the physiological electrical signals sent by the flexible electrode simultaneously, which not only avoids the delay of signal acquisition caused by the activation of useless signal collectors, but also uses multiple signal collectors to improve the efficiency of signal processing, thereby improving the efficiency of signal acquisition.

[0131] In a certain implementation manner of this embodiment, when it is determined that the signal collector in an idle state performs signal acquisition, since the flexible electrode can acquire various types of physiological electrical signals, in order to ensure the accurate acquisition of each type of physiological electrical signal, the signal collector in an idle state can be configured according to actual needs to realize the synchronous acquisition of multiple physiological electrical signals by one signal collector or the synchronous acquisition of multiple physiological electrical signals based on multiple signal collectors.

[0132] Specifically, when controlling the idle-state signal collector to classify the physiological electrical signals sent by the flexible electrode fixed on the surface of the skin to be measured and output the first physiological electrical signals corresponding to the types of the physiological electrical signals, that is, when configuring the signal acquisition parameters corresponding to the idle-state signal collector through step 102, the following steps can be preferentially carried out, including:

[0133] Step S1021: According to the type of the physiological electrical signal to be acquired, determine the types of sub-physiological electrical signals to be acquired by each signal channel in each idle-state signal collector.

[0134] Step S1022: For any idle-state signal collector: for any signal channel of this idle-state signal collector, configure the channel signal acquisition parameters corresponding to this signal channel according to the type of the sub-physiological electrical signal corresponding to this signal channel.

[0135] Step S1023: Take all the channel signal acquisition parameters in this idle-state signal collector as the signal acquisition parameters corresponding to this idle-state signal collector.

[0136] In the above preferentially selected solution, by configuring signal parameters for each idle-state signal collector, the signal collector can use different signal channels to obtain different types of physiological signals, so as to simultaneously collect various physiological electrical signals fed back by the electrode, thereby improving the efficiency of signal acquisition. Or set the same signal collector to collect one type of physiological electrical signal, so as to collect multiple physiological electrical signals through multiple signal collectors, improving the accuracy of signal acquisition while improving the efficiency of signal acquisition.

[0137] In a certain implementation manner of this embodiment, when configuring the signal channels of each idle-state signal collector, based on the main differences in frequency and amplitude among different types of physiological electrical signals, for this, in order to improve the signal screening of the signal collector, specifically, when performing the signal acquisition parameter configuration of the signal channels in step 103, the parameter configuration can be preferentially carried out through the following steps, including:

[0138] Step S1031: For any signal channel of each idle-state signal collector, obtain the signal amplitude and signal frequency according to the type of the sub-physiological electrical signal corresponding to this signal channel.

[0139] Step S1032: Configure the amplification parameter and filtering parameter of this signal channel according to the signal amplitude and the signal frequency.

[0140] Step S1033: Take the amplification parameter and the filtering parameter as the channel signal acquisition parameters corresponding to this signal channel.

[0141] In the above preferred solution, when using the signal collector to collect different physiological electrical signals, by configuring the amplification parameters and filtering parameters of each signal channel, so that each signal channel can only process specific types of physiological electrical signals, it is possible to enable a signal processor to process different types of physiological electrical signals, thereby improving the efficiency and accuracy of signal collection. It is also possible to batch-set the parameters of all signal channels in a signal collector, so that a signal collector collects one type of physiological electrical signal, thereby ensuring the efficiency and accuracy of signal collection through multiple signal collectors.

[0142] On the other hand, the embodiments of the present disclosure also disclose a portable multi-machine multi-electrode multi-type physiological electrical signal collection device for improving the efficiency and accuracy of signal collection. Specifically, for the structural composition of the collection device, please refer to Figure 2 which mainly includes a controller 1, several signal collectors 2 and several flexible electrodes 3.

[0143] Among them, the signal collector 2 is signal-connected to the flexible electrode 3, and any one of the signal collectors 2 is used to obtain the collection signals of all the flexible electrodes 3.

[0144] Several of the flexible electrodes 3 are used to collect various physiological electrical signals under different skin surfaces.

[0145] Any one of the signal collectors 2 is signal-connected to the controller 1.

[0146] The controller 1 is used to perform the following steps:

[0147] Step S1: Based on the preset collection requirements, determine the type of physiological electrical signal to be collected by each signal collector 2.

[0148] Step S2: According to the type of physiological electrical signal to be collected, configure the signal collection parameters corresponding to each signal collector 2.

[0149] Step S3: Send the signal collection parameters to the corresponding signal collector 2, so that the signal collector 2 synchronously obtains the collection signals corresponding to the type of physiological electrical signal to be collected from the corresponding flexible electrode 3 according to the signal collection parameters.

[0150] In a certain implementation manner of the embodiments of the present disclosure, when collecting physiological electrical signals, the shapes of the skin surfaces at different positions are different and some differences are huge. For this reason, in order to ensure that the physiological electrical signals under different skin surface shapes can be obtained according to the flexible electrode 3, several of the flexible electrodes 3 are set to have different shapes, and the flexible electrodes 3 with different shapes are used to adhere to different skin surfaces for collecting various physiological electrical signals under different skin surfaces.

Among them, the signal electrode sheets are arranged in an array on the first surface of the flexible base to form a plurality of signal acquisition channels capable of collecting different types of physiological electrical signals, and then different types of physiological electrical signals are collected simultaneously to improve the signal acquisition efficiency.

[0157] In a certain implementation manner of this embodiment, based on the fact that the signal collector 2 sends its own status data to the controller 1 so that the controller 1 selects an idle signal collector in the idle state. For this reason, a processor is provided in the signal collector 2.

[0158] Among them, the processor is signal-connected to the controller 1 and is used to obtain the status data of the signal collector 2 itself and send the status data to the controller 1 so that the controller 1 executes the following steps:

[0159] Step S4: Obtain the status data sent by the processor to determine a number of idle signal collectors.

[0160] Step S5: Based on the preset acquisition requirements, determine the types of physiological electrical signals to be collected by each of the idle signal collectors.

[0161] In the above preferred solution, a processor is arranged in the signal collector 2 to obtain the status data of each signal collector 2 itself, so that the controller 1 selects a plurality of signal collectors 2 in the idle state according to the status data uploaded by the processor to process all the physiological electrical signals sent by the flexible electrode 3 at the same time, so as to improve the acquisition efficiency of the signal collector and further improve the efficiency of signal acquisition.

[0162] In a certain implementation manner of this embodiment, a signal connection is established between the signal collector 2 and the flexible electrode 3, and various physiological electrical signals sent by the flexible electrode 3 are classified and processed to output different types of physiological electrical signals. For this, a plurality of signal channels are arranged in the signal collector 2, and each of the signal channels is in signal connection with the controller 1.

[0164] Each of the signal channels is in signal connection with the flexible electrode interface of the flexible electrode 3; each of the signal channels receives the channel signal acquisition parameters sent by the controller 1 and a plurality of physiological electrical signals sent by the flexible electrode interface; and obtains the sub-physiological electrical signal corresponding to the channel signal acquisition parameters from the plurality of physiological electrical signals according to the channel signal acquisition parameters.

[0165] The above preferred solution arranges a plurality of signal channels in the signal collector 2, and configures signal parameters for different signal channels of each signal collector 2 in the idle state, so that the signal collector 2 can use different signal channels to obtain different types of physiological signals, and simultaneously collect a variety of physiological electrical signals fed back by the flexible electrode 3, so as to improve the efficiency of signal acquisition.

[0166] In a certain implementation manner of this embodiment, when the controller 1 configures the channel signal acquisition parameters corresponding to any signal channel of any idle-state signal collector according to the type of sub-physiological electrical signal corresponding to the signal channel, it can preferably be realized through the following steps:

[0169] Step S8: The controller 1 takes the amplification parameter and the filtering parameter as the channel signal acquisition parameter corresponding to this signal channel, and sends the channel signal acquisition parameter to the corresponding signal channel.

[0170] In the above preferred solution, when using the signal collector to collect different physiological electrical signals, by configuring the amplification parameter and the filtering parameter of each signal channel, so that each signal channel can only process a specific type of physiological electrical signal, it can not only enable a signal processor 202 to process different types of physiological electrical signals, thereby improving the efficiency and accuracy of signal acquisition, but also batch-set the parameters of all signal channels in a signal collector 2, so that a signal collector 2 collects a type of physiological electrical signal, thereby ensuring the efficiency and accuracy of signal acquisition through multiple signal collectors.

[0171] In a certain implementation manner of this embodiment, based on the amplification parameter and the filtering parameter configured by the controller 202 by the signal channel, corresponding types of physiological electrical signals are collected. For this, a signal amplifier and a filter can be set in any of the signal channels; wherein, the signal amplifier is signal-connected to the controller 1; the input end of the signal amplifier is signal-connected to the flexible electrode interface, and the signal amplifier is used to perform the following steps:

[0177] Step S13: Obtain the sub-physiological electrical signal corresponding to the filtering parameter from the multiple initial sub-physiological electrical signals, and filter the sub-physiological electrical signal to obtain the filtered sub-physiological electrical signal.

[0178] In the above preferred solution, by setting a signal amplifier and a filter in the signal channel, when using the signal collector 2 to collect different physiological electrical signals, by configuring the amplification parameter and the filtering parameter of each signal channel, so that each signal channel can only process a specific type of physiological electrical signal, it can not only enable a signal processor 202 to process different types of physiological electrical signals, thereby improving the efficiency and accuracy of signal collection, but also batch-set the parameters of all signal channels in a signal collector 2, so that a signal collector 2 collects a type of physiological electrical signal, thereby ensuring the efficiency and accuracy of signal collection through multiple signal collectors 2.

[0182] The common-mode rejection driving electrode sheet is used to receive the inverted amplified voltage sent by any of the signal channels and the voltage of each signal electrode sheet, so as to adjust the voltage according to the inverted amplified voltage and send the adjusted voltage to the corresponding signal electrode sheet.

[0183] In the above preferred solution, the common-mode rejection driving electrode sheet is set to adjust the voltage of different signal electrode sheets on the flexible electrode, so that the signal electrode sheet can improve the accuracy of signal collection according to the adjusted voltage.

[0184] In a certain implementation manner of this embodiment, based on the setting of the common-mode rejection driving electrode sheet in the flexible electrode 3, a common-mode rejection driving circuit can be set in the signal collector 2.

In order to ensure the normal operation of the signal collector 202, a collector power supply can be arranged in the signal collector 2. Further, based on actual requirements, in the process of the signal collector 2 obtaining physiological electrical signals through the signal channels and sending them to the controller 1, it may be necessary to perform processing such as analog-to-digital conversion and denoising on the physiological electrical signals. Therefore, a collector main control chip can be arranged in the signal collector 2 to receive the instructions sent by the controller 1 and perform the corresponding processing on the physiological electrical signals output by the signal channels. At the same time, based on the signal connection between the signal collector 2 and the controller 1, it is used to receive the instructions sent by the controller 1 or send corresponding signals to the controller 1. In order to ensure the security of the signal connection or reduce the resource occupation of the collector main control chip and the signal channels, a collector external device can be arranged in the signal collector 2 to make the collector external device responsible for the corresponding communication.

[0189] Specifically, the collector main control chip, the multiple signal channels, and the processor are respectively electrically connected to the collector power supply, so that the collector power supply supplies power to the collector main control chip, the multiple signal channels, and the processor.

[0190] The controller 1 and the collector main control chip are respectively signal-connected to the collector external device, so that the collector external device receives the instructions sent by the controller and sends the instructions to the collector main control chip.

[0191] The processor is signal-connected to the collector main control chip, so that the collector main control chip controls the processor to obtain the status data of the signal collector itself according to the instructions.

[0192] The collector power supply is signal-connected to the collector main control chip, so that the collector main control chip manages the collector power supply according to the instructions.

[0193] All the signal channels are signal-connected to the main control chip of the collector, so that the main control chip of the collector controls any of the signal channels to collect corresponding sub-physiological electrical signals, and obtains each of the sub-physiological electrical signals to store, save or transmit the sub-physiological electrical signals.

At the same time, the main control of the collector is provided to process the physiological electrical signals collected by the signal collection board, so as to adapt to different collection requirements and improve the functionality of the signal collector.

[0195] In a certain implementation manner of this embodiment, when referring to Figure 2 the shown collection device to collect physiological electrical signals, based on the large number of signal collectors 2 and the flexible electrodes 3 used, if the signal collectors 2 and the flexible electrodes 3 are carried scattered for signal collection, it is easy to cause the loss of accessories. To this end, in order to facilitate the carrying of the collection device as Figure 2 shown, a signal collection base station can be additionally provided for storing the signal collectors 2 and the flexible electrodes 3.

[0196] Specifically, base station external devices are provided in the signal collection base station; among them, the signal collection base station includes a base station power supply and a base station main controller; the base station power supply is electrically connected to the base station main controller for supplying power to the base station main controller; the base station main controller is signal-connected to all the signal collectors 2; the base station main controller is signal-connected to the controller 1, so that the controller 1 controls the base station main controller to read the status data of the signal collectors 2 and configure the signal collection parameters of the signal collectors.

[0197] Further, the signal collection base station further includes a base station housing, a plurality of interfaces and a plurality of signal collector storage holes; among them, the base station power supply, the base station main controller, and each of the signal collector storage holes are fixed inside the base station housing; the signal collector storage holes are used for placing any signal collector 2; each of the interfaces is respectively installed on one side of the corresponding signal collector storage hole; the downlink port of any interface is signal-connected to any signal collection channel of all the signal collectors 2 and the base station main controller; the uplink port of the interface is signal-connected to the controller 1, so that the controller 1 controls the signal collection base station and the signal collectors 2 to obtain all the physiological electrical signals sent by the flexible electrodes 3.

[0198] In the above solution, a signal acquisition base station is set as the instruction transfer station between the controller 1 and the signal collector 2. After the signal acquisition base station is set, the controller 1 can synchronously control multiple signal collectors 2 through the signal acquisition base station, thereby improving the control efficiency and the signal acquisition efficiency. At the same time, the signal acquisition base station is provided with base station external devices, and interfaces are set in the base station external devices to complete the control of the signal collector 2 by the controller 1 through the interfaces. At the same time, signal collector storage holes are set in the base station external devices to store multiple signal collectors 2 at the same time, thereby facilitating the carrying of multiple signal collectors 2 for signal acquisition at any time.

[0199] In a certain implementation manner of this embodiment, when using the flexible electrode 3 and the signal collector 2 to collect physiological electrical signals, in order to fix the flexible electrode 3 and the signal collector 2 on the surface of the skin to be measured and stably collect signals, a fixing base can be set to fix the flexible electrode 3 and the signal collector 2.

Secondly, after different physiological electrical signals are collected by the multiple flexible electrodes, multiple signal collectors are used to synchronously obtain and process the multiple physiological electrical signals of the multiple flexible electrodes, so as to improve the data processing efficiency of the signal collectors by reducing the amount of data that each signal collector needs to process. Among them, in order to obtain all the physiological electrical signals collected by the multiple flexible electrodes through the signal collectors, the signal collection type corresponding to each signal collector can be determined first, and the signal collection parameters corresponding to each signal collector can be configured according to the signal collection configuration, and then each signal collector is controlled to select the corresponding type of physiological electrical signal from the physiological electrical signals sent by the flexible electrodes for collection, so as to realize the synchronous collection of multiple types of physiological signals and improve the signal collection efficiency.

[0203] Embodiment 2

[0204] Existing physiological electrical signal collection devices are usually fixed or desktop devices. These devices are bulky and can often only be installed at fixed positions for signal collection, that is, they cannot be easily carried to adapt to a wide range of application scenarios, and at the same time, they cannot adapt to the variability of the detection positions. Often, it is necessary to manually move the device to adapt to different positions on the skin surface, and thus distributed detection cannot be achieved. Further, existing physiological electrical signal collection devices can often only collect single - type signals. If the collection of multiple types of physiological electrical signals is to be realized, multiple devices need to be coordinated for signal collection, which not only requires a long collection time, but also cannot guarantee the accuracy of signal acquisition.

[0205] To solve the above - mentioned technical problems, this embodiment discloses a portable multi - machine and multi - electrode device for collecting multiple types of physiological electrical signals, which realizes flexible, efficient, and accurate collection of physiological electrical signals in different environments and application scenarios. Specifically, for the distributed collection of physiological electrical signals, first, flexible electrodes with different shapes and functions are set in the collection device, so as to select the flexible electrode that fits the skin shape according to the skin shape at the position to be measured and fix it on the position to be measured, and the distributed - position collection of physiological electrical signals can be realized.

[0206] Further, to change the situation that existing devices can only collect single - type physiological electrical signals, this embodiment sets multiple signal channels on the flexible electrodes to realize the collection of multiple types of physiological electrical signals through the multiple signal channels.

[0207] In a certain implementation manner of this embodiment, a flexible electrode is provided, which has multiple signal acquisition channels and a quadrilateral shape, for collecting physiological electrical signals at the positions of the upper and lower arms, the body trunk, the upper and lower legs, the neck, and the unilateral face. Specifically, for the structural composition of the flexible electrode, please refer to Figure 3 , which mainly includes a male gold finger plug-in interface 101, an electrode-side gold finger plug-in interface base 102, a signal connection area 103, a flexible electrode substrate 104, an array signal electrode sheet 105, a reference electrode sheet 106, and a common-mode rejection driving electrode sheet 107.

[0208] Among them, referring to Figure 3 , in order to facilitate the plugging and unplugging of the flexible electrode, the electrode-side gold finger plug-in interface base 102 is set to connect the male gold finger plug-in interface 101. Among them, in order to increase the force on the electrode-side gold finger plug-in interface base 102 and the finger, boss structures can be added on both sides of the electrode-side gold finger plug-in interface base 102.

[0209] Furthermore, the signal connection area 103 is respectively connected to the electrode-side gold finger plug-in interface base 102 and the flexible electrode substrate 104, so as to transmit the physiological electrical signals collected by the array signal electrode sheets 105 arranged in an array on the flexible electrode substrate 104 to the male gold finger plug-in interface 101; among them, several gold finger contacts can be set on the male gold finger plug-in interface 101 and connected to the array signal electrode sheet 105, the reference electrode sheet 106, and the common-mode rejection driving electrode sheet 107 through the connections on the signal connection area 103. Among them, each electrode sheet is uniquely connected to the gold finger contact through the substrate and the wires on the connection area. Among them, necessary signal connections and substrates can be set on the signal connection area 103; among them, the substrate is connected to the flexible electrode substrate 104; the signal connections are signal-connected to the array signal electrode sheet 105, the reference electrode sheet 106, and the common-mode rejection driving electrode sheet 107 for signal transmission. Preferably, the substrate length of the signal connection area 103 can be set according to different requirements.

[0210] Furthermore, referring to Figure 3 , the array signal electrode sheets 105 are arranged in an array on the flexible electrode substrate 104. The position of each array signal electrode sheet 105 on the flexible electrode substrate 104 and the type and shape of the array signal electrode sheet 105 can be set according to specific signal acquisition requirements and signal acquisition positions. Different array signal electrode sheets 105 on the flexible electrode substrate 104 can form separate signal acquisition channels to collect the same type of physiological electrical signals.

[0211] Furthermore, referring to Figure 3, the reference electrode sheet 106 and the common-mode rejection driving electrode sheet 107 are arranged on the same surface of the flexible electrode substrate 104 together with the array signal electrode sheet 105, and their specific positions can be set according to specific signal acquisition requirements. As Figure 3 shown, the reference electrode sheet 106 and the common-mode rejection driving electrode sheet 107 are distributed on the side where the signal connection area 103 is located; the reference electrode sheet 106 is attached to the potential reference point on the flexible electrode substrate 104 and is electrically connected to the male gold finger pluggable interface 101; the common-mode rejection driving electrode sheet 107 is attached to the potential common-mode rejection point on the flexible electrode substrate 104 and is electrically connected to the male gold finger pluggable interface 101.

[0212] In some embodiments of this embodiment, the shape of the flexible electrode can be set according to the shape of the skin surface where the position to be measured is located. Specifically, the shape of the flexible electrode substrate 104 is set according to the shape of the skin surface, and the arrangement modes of the array signal electrode sheet 105, the reference electrode sheet 106, and the common-mode rejection driving electrode sheet 107 on the flexible electrode substrate 104 are changed according to the shape of the flexible electrode substrate 104.

[0213] Preferably, in some embodiments of this embodiment, a flexible electrode is provided for simultaneously collecting physiological electrical signals at the positions of large-area skin and small-area skin, and the specific structural composition of the flexible electrode is referred to Figure 4 . As Figure 4 shown, two independent electrode signal electrode sheets 201 with single-channel wiring are added to the flexible electrode shown in Figure 3 . Each of the independent electrode signal electrode sheets 201 is distributed on an independent independent electrode substrate 202.

[0214] Refer to Figure 4The flexible electrode shown, the flexible electrode substrate 104 is used to cover the position where large-area skin is located, such as the abdomen, one side of the face, etc., so as to collect corresponding physiological electrical signals through the array signal electrode sheets 105 arranged on the flexible electrode substrate 104. And the independent electrode substrate 202 is used to cover the position where small-area skin is located, such as around the heart, eyes, etc., so as to collect corresponding physiological electrical signals through the independent electrode signal electrode sheets 201 arranged on the independent electrode substrate 202, such as electrocardiogram signals around the heart, electrooculogram signals of the eyes, etc. The independent electrode signal electrode sheet 201 is connected to the signal connection area 103 through an independent signal connection line, that is, the independent electrode connection line 203, and is used to send the collected physiological electrical signals to the male gold finger pluggable interface 101. Specifically, in order to enable the male gold finger pluggable interface 101 to receive the physiological electrical signals transmitted by the independent electrode connection line 203, an independent wiring joint 204 can be provided at the connection between the independent electrode connection line 203 and the signal connection area 103, so as to complete the signal transmission through the independent wiring joint 204.

[0215] In other ways of this embodiment, a flexible electrode is also provided for collecting physiological electrical signals at positions with specific shape features, such as an electrode customized according to the facial shape features of the human body, such as Figure 9 shown.

[0216] Specifically, referring to Figure 5 , such as Figure 5 shown, the shape of the flexible electrode substrate 104 of the flexible electrode is set to be consistent with the shape of the face based on the appearance features of the face. Among them, referring to Figure 5 shown, the flexible electrode substrate 104 of the flexible electrode is used to cover the face for collecting full-face electromyogram and electrooculogram. Referring to Figure 5 shown, the array signal electrode sheets 105 are evenly distributed at the blank positions on the flexible electrode substrate 104, while the reference electrode sheet 106 and the common-mode rejection driving electrode sheet 107 are respectively arranged at the upper left and upper right of the face. Specifically, when using Figure 5 shown flexible electrode to collect physiological electrical signals of the face, the multi-channel integrated electrode can be fixed to the human skin surface by using double-sided tape or straps as needed.

[0217] In a certain implementation manner of this embodiment, referring to Figures 3 to 5 shown, according to the collection requirements of physiological electrical signals, flexible electrodes with different shapes are fixed on the skin surfaces at different positions of the human body. For example, Figure 5 shown flexible electrode is fixed on the left and right arms of the human body, Figure 4 shown flexible electrode is fixed on the abdomen and the heart, while Figure 5The flexible electrode shown is fixed to the face to simultaneously collect physiological electrical signals at different positions of the human body, thereby realizing the distributed collection of physiological electrical signals and improving the efficiency of signal collection. In particular, when using electrodes with a multi-channel, high-density array arrangement and a two single-channel wiring independent integration method as shown in Figure 4 , different positions where the electrode patches can be attached form a type of distributed collection based on different electrode configurations.

[0218] In some embodiments of this example, since the physiological electrical signals collected by the flexible electrode are relatively weak and a single flexible electrode can collect multiple physiological electrical signals, to ensure the accuracy of the subsequently obtained physiological electrical signals and accurately distinguish each type of physiological electrical signal collected by the flexible electrode, a signal collector that is signal-connected to the flexible electrode is required. The signal collector is used to receive the physiological electrical signals sent by the flexible electrode and classify and process the physiological electrical signals to output the physiological electrical signals corresponding to each type respectively.

[0219] Specifically, to implement the functions of the signal collector, the structure of the signal collector is set as shown in Figures 6 to 7 . Specifically, referring to Figure 6 and Figure 7 , the signal collector mainly includes a signal collector housing 401, a female electrode interface 402, a switch 403, and a female signal power supply interface 404 of the signal collector. Among them, the signal collector is correspondingly connected to the male gold finger plug interface 101 of the flexible electrode through the female electrode interface 402 to realize the signal transmission between the signal collector and the flexible electrode through the female electrode interface 402 and the male gold finger plug interface 101. Among them, a number of gold finger contacts are provided on the female electrode interface 402, and their quantity and positions correspond one-to-one to the gold finger contacts on the male gold finger plug interface 101 and are respectively connected one-to-one to the independent tiny signal amplifiers and filters inside the signal collector.

[0220] Furthermore, since the signal collector needs to classify and process the physiological electrical signals sent by the flexible electrode, necessary signal circuit boards can be provided inside the signal collector housing 401, which include necessary multi-channel signal processing chips and a common-mode rejection drive reference processing circuit.

[0221] Among them, the multi-channel signal processing chip includes a plurality of independent signal channels. Each of the signal channels is respectively communicatively connected to a signal acquisition channel composed of several array signal electrode sheets 105 in the flexible electrode. Specifically, the positive electrode of each signal channel in the multi-channel signal acquisition chip is electrically connected to the output end of the corresponding signal acquisition channel through the male gold finger pluggable interface 101 and the female electrode interface 402; the negative electrode of each signal channel in the multi-channel signal acquisition chip is electrically connected to the reference electrode sheet 106 through the male gold finger pluggable interface 101 and the female electrode interface 402; the voltage output end of each signal channel in the multi-channel signal processing chip is electrically connected to the input end of the common-mode rejection driving circuit through the male gold finger pluggable interface 101 and the female electrode interface 402, for inputting the average voltage of the acquired physiological electrical signal into the common-mode rejection driving circuit; the output end of the common-mode rejection driving circuit is electrically connected to the common-mode rejection driving electrode sheet 107 through the male gold finger pluggable interface 101 and the female electrode interface 402, for performing reverse amplification on the average voltage and outputting the inversely amplified average voltage to the common-mode rejection driving electrode sheet 107.

[0222] Particularly, since the differences among various physiological electrical signals such as electromyogram, electroencephalogram, electrocardiogram, electrooculogram, and skin electricity are usually manifested as differences in amplitude and frequency, in order to synchronously acquire multiple physiological electrical signals, the multi-channel micro-signal amplifiers and filters included in the multi-channel signal processing chip are independent of each other, and parameters such as amplification and filtering can be independently configured, and are simultaneously independently connected to different channels of the flexible electrode. Specifically, that is, the multi-channel micro-signal amplifiers and filters are connected to form a signal channel, and the multi-channel micro-signal amplifiers and filters in each signal channel are independent of each other. Particularly, the multi-channel micro-signal amplifier is a programmable gain micro-signal amplifier, and the gain of the micro-signal amplifier corresponding to each channel can be set as needed to adapt to the acquisition of physiological electrical signals such as electroencephalogram, electromyogram, electrocardiogram, and electrooculogram in different ranges. The filter is a programmable cascaded filter circuit, and the gain of the filter corresponding to each channel can be set as needed to adapt to the acquisition of physiological electrical signals such as electroencephalogram, electromyogram, electrocardiogram, and electrooculogram in different ranges. Further, the common-mode rejection driving reference processing circuit is mainly composed of a non-inverting follower circuit and an inverting amplification circuit composed of operational amplifiers in cascade.

[0223] Refer to Figure 7The signal collector shown, after a multi-channel signal processing chip is arranged on the signal circuit board to process various physiological electrical signals obtained, in order to accurately send the processed physiological electrical signals to other devices for processing, storage, etc. of the physiological electrical signals, a signal processor, a memory, wireless and wired signal transceivers, a battery, a power management circuit, a signal indicator, etc. can also be arranged on the signal circuit board. Among them, the signal processor simultaneously processes various physiological electrical signals output by the multi-channel signal processing chip to send the processed signals to other devices.

[0224] In a certain implementation manner of this embodiment, referring to Figure 3 - Figure 5 the flexible electrode shown is signal-connected to Figures 6 to 7 the signal collector shown, so that the physiological electrical signals collected by different signal acquisition channels in the flexible electrode are sent to each signal channel in the multi-channel signal processing chip, so that when each signal channel outputs a type of processed physiological electrical signal, the signal transmission mode between the signal acquisition channel in the flexible electrode and the signal channel is as Figure 8 shown.

[0225] Referring to Figure 8 , S2 represents the flexible electrode, and S1 represents the signal collector signal-connected to the flexible electrode. Among them, PGA in S1 represents a programmable multi-stage differential operation amplifier circuit, and Fil represents a programmable cascaded filter circuit. Each signal channel in the signal collector includes an independent programmable multi-stage differential operation amplifier circuit and a programmable cascaded filter circuit, where 1, 2, 3,..., n represent the number of signal channels; IA in S2 represents a common-mode rejection drive reference processing circuit, which is mainly composed of a non-inverting follower circuit and an inverting amplifier circuit cascaded by operational amplifiers; MCU represents the signal processor in the signal collector, and necessary analog-to-digital conversion ADC circuits, control circuits, power management circuits, etc. can be set in the signal processor; RF represents a data receiving interface.

[0226] And R in S1 represents the reference electrode piece in the flexible electrode, such as Figure 3 , Figure 4 , Figure 5 the reference electrode piece 106 shown; 1, 2,..., n represent different signal acquisition channels in the flexible electrode composed of different array signal electrode pieces 105; G represents a common-mode rejection drive electrode piece, such as Figure 3 , Figure 4 , Figure 5 the common-mode rejection drive electrode piece 107 shown.

[0227] Specifically, referring to Figure 8, when the female electrode interface 402 of the signal collector is signal-connected to the male finger-plug interface 101 of the flexible electrode, the positive signal input terminal “+” of the PGA in each signal channel in the signal collector is independently connected to the array signal electrode sheet 105 in the flexible electrode shown in Figures 3 to 5 or the independent electrode signal electrode sheet 201. And the negative signal input terminals “-” of the PGA in each signal channel in the signal collector are shorted together and then connected to the reference electrode sheet 105 in the flexible electrode shown in Figures 3 to 5 . The analog power neutral terminals “C” of the PGA in each signal channel in the signal collector are shorted together and then connected to the common-mode rejection driving electrode sheet 107 in the flexible electrode shown in Figures 3 to 5 through the common-mode rejection driving reference processing circuit.

[0228] Referring to Figure 8 for the connection method shown, in use, the reference electrode sheet R and the common-mode rejection driving electrode sheet G are attached to one position of the human body along with the flexible electrode, and the array signal electrode sheets or independent electrode signal electrode sheets of different channels are attached to the corresponding human body positions according to different physiological electrical signals to be collected. Among them, the PGA and Fil on different channels are based on their own configured parameters, including amplification factors and filtering parameters, etc. In particular, each channel can be independently configured to adapt to the acquisition requirements of different physiological electrical signals, and classify and process the physiological signals sent by the flexible electrode. In particular, when multiple signal collectors are used for distributed synchronous acquisition of different physiological electrical signals, if different signal collectors collect different physiological electrical signals and the same signal collector collects the same physiological electrical signals, different configurations can be made for different signal collectors, and the parameters of different channels of the same signal collector can be batch-set to achieve the effect of rapid configuration.

[0229] In a certain implementation manner of this embodiment, when based on Figure 3 , Figure 4 or Figure 5 for the flexible electrode shown and Figures 6 to 7 for the signal collector shown to collect the physiological electrical signals at different positions of the human body. Since the flexible electrode and the signal collector are small in volume and independent of each other, in order to ensure the accuracy of the physiological electrical signal acquisition, it is necessary to fix the flexible electrode and the signal collector at the position to be measured to stably collect signals.

[0230] For this, this embodiment provides a fixing base to fix the flexible electrode and the signal collector. Specifically, for the structural composition of the fixing base, please refer to Figure 9 , which mainly includes a flexible base 601, a base strap 602, a movable buckle 603, and a signal collector elastic fixing band 604.

[0231] Referring to Figure 9 , the flexible base 601 can be made of a material with a certain strength and flexibility, and is used to adhere to the human body surface or on the flexible electrode. Its upper part is used to place the signal collector; the base strap 602 is used to Figure 9 fix the fixed base shown in

[0232] to the human body; and the movable buckle 603 is used to stretch and fix the base strap 602; wherein, one end of the fixed base strap 602 is fixedly connected to one end of the flexible base 601, and the other end is movably wound around the movable buckle 603. The signal collector elastic fixing band 604 has a certain elasticity and is used to fix the signal collector to the flexible base 601.

[0232] In a certain implementation manner of this embodiment, based on Figure 9 the fixed base shown in Figure 3 , Figure 4 or Figure 5 when fixing the flexible electrode shown in Figure 8 and the signal collector shown in Figure 10 on the surface of the skin to be measured, it can be referred to

[0233] . Then, the fixed base is placed on the flexible electrode S3, and the base strap 602 is used to fix the fixed base S4 and the flexible electrode S3 on the human arm or other parts. The signal collector elastic fixing band 604 fixes the signal collector S2 to the flexible base 601, and the male gold finger plug-in interface 101 is fixed to the female electrode interface 402, so that the signal on the flexible electrode S3 is connected to the signal collector S2.

[0233] Furthermore, when the signal collector and the flexible electrode are not in use, the signal collector, the flexible electrode and the fixed base need to be properly stored, and functions such as charging the signal collector and signal transmission with the signal collector are carried out during the storage process, so that the entire acquisition device is convenient to carry and move to adapt to different usage scenarios.

[0234] For this, in a certain implementation manner of this embodiment, a signal base station is set up as Figures 11 to 12 shown. Referring to Figures 11 to 12 , the signal base station mainly includes a base station cover 701, a base station box body 702, an accessory storage hole 703, a signal collector storage hole 704, a male signal collector signal power interface 705, a base station box body interface 706, a base station switch 707, etc.

[0235] Furthermore, according to the actual requirements of signal acquisition, in addition to Figures 11 to 12As shown in the figure, the signal base station box also contains necessary circuit boards, which include necessary signal processors, memory, wireless and wired signal transceivers, batteries, power management circuits, signal indicators, etc. In particular, the signal collector receiving hole 704 can receive a number of signal collectors such as Figures 6 to 7 as shown, and the accessory receiving hole 703 can receive flexible electrodes such as Figures 3 to 5 as shown, fixed bases such as Figure 9 as shown, and other items.

[0236] Referring to the signal base station shown in Figures 11 to 12 as shown, the signal collector as shown in Figures 6 to 7 can be placed into the signal collector receiving hole 704. When the signal collector as shown in Figures 6 to 7 is placed into the signal collector receiving hole 704, the male signal power interface 705 of the signal base station and the female signal power interface 404 of the signal collector are docked. At this time, the signal base station can charge the signal collector through the male signal power interface 705 and the female signal power interface 404, and at the same time, the signal base station and the signal collector can complete data transmission through the male signal power interface 705 and the female signal power interface 404.

[0237] In some embodiments of this embodiment, referring to the signal collector shown in Figures 6 to 7 as shown, the signal collector is independently started by manually starting the switch 403 on the signal collector. At this time, the started signal collector saves the data into the memory of the signal collector.

[0238] In some embodiments of this embodiment, referring to the signal base station shown in Figures 11 to 12 as shown and the signal collector shown in Figures 6 to 7 as shown, the switch 403 on the signal collector and the base station switch 707 on the signal base station are manually started so that the several signal collectors and the signal base station can work together. At this time, the several working signal collectors send the data to the signal base station in a wired or wireless manner, and the signal base station can process, analyze, and save the data in real time.

[0239] In some embodiments of this embodiment, referring to the signal base station shown in Figures 11 to 12 as shown and the signal collector shown in Figures 6 to 7 as shown, a controller can be set in the acquisition device to control the signal base station and the signal collector. Among them, the controller can be a computer, mobile phone, or tablet equipped with upper computer software and other devices that can display, process, analyze, and save data in real time.

[0240] In an implementation manner of this embodiment, when the controller controls the signal collector, the controller configures the parameters of the multi-channel micro-signal amplifier and filter in the signal collector, and sends the parameters to the signal collector, so that the signal collector can collect different physiological electrical signals according to the parameters. At the same time, the controller can also send an instruction to the signal processor of the signal collector to control the power supply of the signal collector and control the signal collector to obtain its own status data and feedback the status data.

[0241] Further, when the controller acquires the physiological electrical signals fed back by the signal collector, since multiple signal collectors feed back signals simultaneously, to ensure the accuracy of signal transmission, the controller can control the signal collectors to perform signal synchronization. Specifically, when the controller controls the signal collectors to perform clock synchronization, the following two schemes can be preferentially adopted:

[0242] One; the controller controls the signal collectors to achieve hardware synchronization of the master and slave machines; specifically, the controller selects one of several signal collectors to be used as the master machine, and other signal collector machines as slave machines. Using the time of the master machine as the reference, the slave machines are connected to the master machine in sequence, so that each slave machine records the clock difference between it and the master machine. During signal acquisition, the recorded clock differences are used as the synchronization reference.

[0243] Two: when the controller acquires the signals collected by several signal collectors to be used through wireless or wired means, when the controller receives the data, the signal alignment method is based on the signal reception time.

[0244] In an implementation manner of this embodiment, when the controller controls the signal collector as shown in Figures 11 to 12 through the signal base station as shown in Figures 6 to 7 the working signal collectors send the data to the signal base station through wired or wireless means. The signal base station sends the signal to a computer, mobile phone or tablet installed with upper computer software through wired or wireless means. The computer, mobile phone or tablet installed with upper computer software can display, process, analyze and save the data in real time.

[0245] Further, the clock synchronization of the signal collectors can be performed based on the signal base station. Specifically, the specific process of the clock synchronization is as follows:

[0246] After the signal collectors to be synchronized are powered on, they are respectively placed into the signal collector receiving holes 704 of the signal base station;

[0247] The signal base station sends out a hardware synchronization signal. Each signal collector records its respective initial clock T0 at this time. When collecting and using signals, the signals collected by each signal collector carry the difference Tx between the clock at the time of signal collection and its respective T0. Each signal collector uses Tx as a reference to align and synchronize the signals.
