[0034] The fixed headgear for electroencephalogram examination in neurology is a medical fixed cap used during electroencephalogram examination to help fix the electroencephalogram electrodes, ensure that the electrodes can be accurately placed at the predetermined positions on the patient's head, and thus obtain accurate and reliable electroencephalogram data.

[0035] In the fixed headgear for electroencephalogram examination in related technologies, after the electrodes are fixed, if the quality of the electroencephalogram data signals obtained by the electrodes is not high (poor signal stability, poor signal credibility, etc.), it is usually necessary for people to manually adjust the electrode positions multiple times until the quality of the electroencephalogram data signals obtained by the electrodes is good, which is time-consuming and laborious.

[0036] Based on this, to improve the technical problem in related technologies that it is time-consuming and laborious to manually adjust the electrode positions multiple times by people to a position where good-quality electroencephalogram data signals can be obtained, the embodiments of this application provide the following solutions.

[0037] Please refer to Figure 1The embodiment of the present application provides a fixed headgear 100 for electroencephalogram examination in neurology, and the fixed headgear 100 for electroencephalogram examination in neurology includes a wearing part 10 and a plurality of fixing parts 20, wherein:

[0038] The wearable portion 10 is used to be worn on the user's head. The wearable portion 10 is provided with a plurality of moving grooves and a plurality of positioning holes, and each positioning hole corresponds to at least one moving groove.

[0039] The fixing part 20 is movably arranged on the wearable part 10, and the fixing part 20 includes a mounting mechanism 21, a rotating mechanism 22 and a fixing mechanism 23. The mounting mechanism 21 is movably arranged on the wearable part 10 along a movable groove, the rotating mechanism 22 is rotatably arranged on the mounting mechanism 21, and the fixing mechanism 23 is arranged on the rotating mechanism 22.

[0040] Among them, the mounting mechanism 21 is used to fix the rotating mechanism 22 to the wearable part 10, the rotating mechanism 22 is used to drive the fixing mechanism 23 to rotate around the rotating mechanism 22, and / or drive the fixing mechanism 23 to approach or move away from the rotating mechanism 22, the fixing mechanism 23 can pass through the positioning hole to contact the user's scalp, and the fixing mechanism 23 is used to contact the electrode to the user's scalp.

[0041] It can be understood that the wearing part 10 is a helmet-like structure. For example, the wearing part 10 can be a plastic helmet, a carbon fiber helmet, etc., but is not limited thereto. The positioning hole is a hole that passes through the wearing part 10. For example, the positioning hole can be a circular hole, a square hole, etc., but is not limited thereto. The moving groove is a groove opened on the side of the wearing part 10 away from the user's head. For example, the moving groove can be a T-slot, a triangular groove, etc., but is not limited thereto.

[0042] The fixing part 20 is a device that can fix the electrode on the user's scalp. The mounting mechanism 21 is a mechanism that can fix the rotating mechanism 22 and the fixing mechanism 23 on the wearable part 10. For example, the mounting mechanism 21 can be a magnetic fixing device, a conflict fixing device composed of bolts and nuts, etc., but is not limited to this. The rotating mechanism 22 is a mechanism that can rotate and drive the fixing mechanism 23 to rotate. For example, the rotating mechanism 22 can be a cylindrical clamping rotating device, a cylindrical sleeve rotating device, etc., but is not limited to this. The fixing mechanism 23 is a mechanism that can fix the electrode on the user's scalp. For example, the fixing mechanism 23 can be a buffer cylinder, a micro cylinder, etc., but is not limited to this.

[0043] From the above, it can be seen that the neurology EEG examination fixed headgear 100 provided in the embodiment of the present application fixes the neurology EEG examination fixed headgear 100 on the user's head through the wearable part 10, and then fixes the mounting mechanism 21 and the rotating mechanism 22 on the wearable part 10 through the fixing mechanism 23, and then drives the fixing mechanism 23 to move above the scalp where the electrode needs to be fixed by the rotation of the rotating mechanism 22, and finally fixes the electrode through the positioning hole in a resistance manner on the user's scalp to obtain a position where a brain wave signal of qualified quality can be obtained through the fixing mechanism 23, thereby avoiding the time-consuming and laborious problem of manually moving the electrode to a position where a brain wave signal of qualified quality can be obtained.

[0044] In some embodiments, please refer to Figures 2 to 3 The mounting mechanism 21 includes a first mounting member 211 , at least one fixing member 212 and a second mounting member 213 .

[0045] At least one fixing member 212 The fixing member 212 is rotatably disposed on the first mounting member 211 .

[0046] The second mounting member 213 is connected to an end of the fixing member 212 away from the first mounting member 211 .

[0047] Among them, the second mounting member 213 is arranged on the wearable part 10 and is located in the movable groove, the fixing member 212 passes through the movable groove and is respectively connected to the first mounting member 211 and the second mounting member 213, the wearable part 10 is partially located between the first mounting member 211 and the second mounting member 213, the rotating mechanism 22 is rotatably arranged on the side of the first mounting member 211 away from the wearable part 10, and the fixing member 212 is used to drive the second mounting member 213 to approach or move away from the first mounting member 211.

[0048] It can be understood that the first mounting member 211 is a plate-like structure, for example, the first mounting member 211 can be a plastic plate, an aluminum plate, etc., but not limited thereto. The fixing member 212 is a mechanism that can drive the second mounting member 213 to move closer to or away from the first mounting member 211, for example, the fixing member 212 can be a tightening device composed of bolts and nuts, a guide rod cylinder, etc., but not limited thereto. The second mounting member 213 is a plate-like structure, and the width of the second mounting member 213 can be less than the width at the bottom of the moving groove and greater than the width at the notch of the moving groove, for example, the second mounting member 213 can be a plastic plate, an aluminum plate, etc., but not limited thereto.

[0049] With such a setting, by making the width of the second mounting member 213 smaller than the width at the bottom of the moving groove and larger than the width at the notch of the moving groove, the second mounting member 213 can move along the moving groove within the moving groove without falling out from the notch of the moving groove. Then, the fixing member 212 drives the second mounting member 213 to approach or move away from the first mounting member 211, so that the second mounting member 213 and the first mounting member 211 simultaneously abut against the wearing part 10 located between the second mounting member 213 and the first mounting member 211, thereby preventing the second mounting member 213 and the first mounting member 211 from moving.

[0050] In some embodiments, please refer to Figures 2 to 3 together. The rotating mechanism 22 includes a rotating cylinder 221, a first rotating member 222, a rotating rod 223, a rotating driving member 224, a second rotating member 225, and a telescopic driving member 226.

[0051] The rotating cylinder 221 is disposed on the first mounting member 211, and a rotating accommodation space is provided inside the rotating cylinder 221.

[0052] The first rotating member 222 is located inside the rotating accommodation space and is disposed on the side of the rotating cylinder 221 close to the first mounting member 211.

[0053] The rotating rod 223 is located inside the rotating accommodation space and is disposed on the side of the first rotating member 222 away from the first mounting member 211.

[0054] The rotating driving member 224 is located inside the rotating accommodation space and is disposed on the rotating rod 223.

[0055] The second rotating member 225 is located inside the rotating accommodation space and is disposed on the power output end of the rotating driving member 224. The second rotating member 225 meshes with the first rotating member 222.

[0056] The telescopic driving member 226 is disposed on the side of the rotating rod 223 away from the first rotating member 222.

[0057] Wherein, the rotating driving member 224 is used to drive the second rotating member 225 to rotate, thereby driving the rotating rod 223 to rotate, and further driving the telescopic driving member 226 to rotate. The fixing mechanism 23 is disposed on the telescopic rod of the telescopic driving member 226, and the telescopic driving member 226 is used to drive the fixing mechanism 23 to approach or move away from the rotating cylinder 221.

[0058] It can be understood that the rotating cylinder 221 is a cylindrical tubular structure. For example, the rotating cylinder 221 can be a plastic cylinder, an aluminum cylinder, etc., but is not limited thereto. The first rotating member 222 is a kind of gear. For example, the first rotating member 222 can be a spur gear, a helical gear, etc., but is not limited thereto. The rotating rod 223 is a cylindrical structure. For example, the rotating rod 223 can be a plastic rod, an aluminum rod, etc., but is not limited thereto. The rotation driving member 224 is a kind of driving mechanism. For example, the rotation driving member 224 can be a stepper motor, a brushless motor, etc., but is not limited thereto. The second rotating member 225 is a kind of gear. The second rotating member 225 can be in the same plane as the first rotating member 222. For example, the first rotating member 222 can be a spur gear, a helical gear, etc., but is not limited thereto. The telescopic driving member 226 is a mechanism capable of driving the fixing mechanism 23 to approach or move away from the rotating cylinder 221. For example, the telescopic driving member 226 can be a micro cylinder, a slide cylinder, etc., but is not limited thereto.

[0059] With such a setting, by arranging the first rotating member 222, the rotating rod 223, the rotation driving member 224, and the second rotating member 225 in the rotation accommodating space of the rotating cylinder 221, it is avoided that the user's hair enters the internal mechanical structure and causes harm to the user. When the rotation driving member 224 drives the second rotating member 225 to rotate clockwise or counterclockwise, since the first rotating member 222 is fixedly arranged on the rotating cylinder 221, the second rotating member 225 meshing with the first rotating member 222 can move clockwise or counterclockwise along the circumferential direction of the first rotating member 222, thereby driving the rotation driving member 224, the rotating rod 223, and the telescopic driving member 226 to rotate clockwise or counterclockwise along the circumferential direction of the first rotating member 222, so that the projection of the driving direction of the telescopic driving member 226 in the direction parallel to the user's neck and towards the user's leg can contact the position on the user's scalp where the electrode needs to be fixed.

[0060] In some embodiments, please refer to Figure 2 and Figure 4 , the fixing mechanism 23 includes a fixing driving member 231, a limiting cylinder 232, a limiting plate 233, and a plurality of elastic members 234.

[0061] The fixing driving member 231 is arranged on the telescopic rod of the telescopic driving member 226.

[0062] The limiting cylinder 232 is arranged on one side of the fixing driving member 231 close to the power output end of the fixing driving member 231. The limiting cylinder 232 has a limiting accommodating space inside. A limiting through hole communicating with the limiting accommodating space is opened on the side of the limiting cylinder 232 away from the fixing driving member 231. The power output shaft of the fixing driving member 231 can be partially located in the limiting accommodating space and partially pass through the limiting through hole.

[0063] The limiting plate 233 is located within the limiting accommodation space and is disposed on the power output shaft of the fixed driving member 231.

[0064] A plurality of elastic members 234 are located within the limiting accommodation space and between the limiting plate 233 and the limiting through-hole. One end of the elastic member 234 is connected to the limiting plate 233, and the other end of the elastic member 234 is connected to the inner wall of the limiting cylinder 232.

[0065] Wherein, the end of the power output end of the fixed driving member 231 away from the telescopic driving member 226 is used to dispose the electrode. The fixed driving member 231 is used to drive the electrode to abut against and touch the user's scalp, or drive the electrode away from the user's scalp.

[0066] It can be understood that the fixed driving member 231 is a driving mechanism capable of driving the electrode to abut against or away from the user's scalp. For example, the fixed driving member 231 can be a micro cylinder, a slide cylinder, etc., but is not limited thereto. The limiting cylinder 232 is a cylindrical structure. For example, the limiting cylinder 232 can be a plastic cylinder, an aluminum cylinder, etc., but is not limited thereto. The limiting plate 233 is a plate-like structure, and the area of the limiting plate 233 can be larger than the area of the limiting through-hole. For example, the limiting plate 233 can be a plastic plate, an aluminum plate, etc., but is not limited thereto. The elastic member 234 is a spring. For example, the elastic member 234 can be a helical spring, an annular spring, etc., but is not limited thereto.

[0067] With such a setting, when it is necessary to abut the electrode against the user's scalp, the fixed driving member 231 drives the power output end closer to the user's scalp, and the electrode disposed at the end of the power output end closer to the user's scalp abuts against the user's scalp with a preset force (a force that can fix the electrode to the user's scalp but will not cause harm to the user). The limiting plate 233 can prevent the power output end of the fixed driving member 231 from being too close to the user's scalp. When it is not necessary to abut the electrode against the user's scalp, the fixed driving member 231 drives the power output end away from the user's scalp, and at the same time, the elastic member 234 drives the limiting plate 233 away from the user's scalp, so that the electrode in contact with the user's scalp does not come into contact with the user's scalp, avoiding the problem of time-consuming and laborious manual movement of the electrode.

[0068] The embodiment of the present application further provides a control method for a fixed headgear for electroencephalogram examination in neurology. The control method for a fixed headgear for electroencephalogram examination in neurology includes:

[0069] Obtain basic information; wherein, the basic information includes at least one distribution information, the distribution information includes at least one fixed area, at least one position information corresponding to the fixed area, and a moving range corresponding to the position information, the fixed area reflects the hole area coverage area of the positioning hole, the position information reflects the relative position of the fixing part 20 fixed on the moving groove corresponding to the positioning hole corresponding to the fixed area, and the moving range reflects the movable area of the fixing mechanism 23 of the fixing part 20 corresponding to the position information on the fixed area corresponding to the position information.

[0070] Obtain analysis information based on the basic information; wherein, the analysis information includes at least one intensity information corresponding to the distribution information, the intensity information includes the electroencephalogram signals received at each different position on the fixing part 20 corresponding to the position information corresponding to the fixed area within a preset time period by the electrodes on the fixing part 20, and the electroencephalogram signals are the electroencephalogram signals generated by the user in a preset environment.

[0072] Control the fixing part 20 to fix the electrode based on the electrode fixing position information.

[0073] As can be seen from the above, for the control method of the fixed headgear for electroencephalogram examination in neurology provided by the embodiments of the present application, by obtaining at least one basic information including at least one distribution information including at least one fixed area, at least one position information corresponding to the fixed area, and a moving range corresponding to the position information, the area on the user's scalp where the electrode can be fixed and the position of the fixing part 20 that can fix the electrode within this area are determined, providing a basis for subsequent steps. Then, based on the basic information, analysis information including at least one intensity information corresponding to the distribution information and reflecting the electroencephalogram signals at each different position on the fixed area within a preset time period is obtained, providing a basis for determining the fixing position of the electrode on the user's scalp. Further, based on the analysis information, electrode fixing position information including at least one contact position reflecting the position of the electrode on the corresponding fixed area is obtained, avoiding abnormal electroencephalogram signals received by the electrode due to inappropriate contact positions between the electrode and the user's scalp, thus affecting the doctor's judgment. Finally, based on the electrode fixing position information, the fixing part 20 is controlled to fix the electrode, reducing manual operation and improving work efficiency.

[0074] The control method for the fixed headgear in neurology electroencephalogram examination provided by the embodiments of the present application can be applied to the fixed headgear 100 for neurology electroencephalogram examination. At this time, the fixed headgear 100 for neurology electroencephalogram examination is the execution subject of the control method for the fixed headgear in neurology electroencephalogram examination provided by the embodiments of the present application. The embodiments of the present application do not impose any restrictions on the specific type of the fixed headgear 100 for neurology electroencephalogram examination.

[0075] To better understand the control method for the fixed headgear in neurology electroencephalogram examination provided by the embodiments of the present application, the following provides an exemplary introduction to the specific implementation process of the control method for the fixed headgear in neurology electroencephalogram examination provided by the embodiments of the present application.

[0076] Figure 5 The schematic flowchart of the control method for the fixed headgear in neurology electroencephalogram examination provided by the embodiments of the present application is shown. The control method for the fixed headgear in neurology electroencephalogram examination includes:

[0077] S100, obtaining basic information; wherein, the basic information includes at least one distribution information, the distribution information includes at least one fixed area, at least one position information corresponding to the fixed area, and a moving range corresponding to the position information.

The electroencephalogram signals are the electroencephalogram signals generated by the user in a preset environment.

[0080] It can be understood that the preset environment can be the environment where the user is watching a specific video or the environment where the user is in a calm state, etc., but not limited to this. The way to obtain the analysis information based on the basic information can be to receive the brain wave signals received by the fixed part 20 at different positions within the corresponding movement range and analyze the quality of the received brain wave signals, or to send the basic information to the doctor and then receive the data sent back by the doctor, etc., but not limited to this. Obtaining the analysis information based on the basic information can provide a basis for subsequent steps.

[0081] In a possible implementation, please refer to Figure 6 , S200, obtaining analysis information based on the basic information, including:

[0082] S210, obtaining regional intensity information based on the distribution information; wherein, the regional intensity information corresponds to a fixed region, and the regional intensity information includes at least one intensity information.

[0083] It can be understood that the way to obtain the regional intensity information based on the distribution information can be to control the fixed part 20 to respectively obtain the user's brain wave signals at different positions within the corresponding movement range and confirm the brain wave signals obtained at different positions as the regional intensity information, or to receive the specific position information input by the doctor and confirm the brain wave signals obtained by the fixed part 20 at the specific position information as the regional intensity information, etc., but not limited to this. Obtaining the regional intensity information based on the distribution information can provide a basis for subsequent steps.

[0084] In a possible implementation, please refer to Figure 6 , S210, obtaining regional intensity information based on the distribution information, including:

[0085] S211, obtaining acquisition points based on the movement range; wherein, the acquisition points reflect the positions of the electrodes on the movement range, and the number of acquisition points is at least 2.

[0086] It can be understood that the way to obtain the acquisition points based on the movement range can be to divide the movement range into multiple regions with equal areas according to a preset number and confirm the positions where at least three regions are in contact as the acquisition points, or to send the movement range to the doctor and confirm the position data sent back by the doctor as the acquisition points, etc., but not limited to this. Obtaining the acquisition points based on the movement range can provide a basis for subsequent steps.

[0087] In a possible implementation, please refer to Figure 6 , S211, obtaining acquisition points based on the movement range, including:

[0088] S2111, establishing an analysis coordinate system based on the movement range and ensuring that the movement range is placed within the first quadrant of the analysis coordinate system.

[0089] It can be understood that establishing an analysis coordinate system based on the movement range means projecting the movement range onto a two-dimensional coordinate system and ensuring that any point on the projection of the movement range is within the first quadrant of the two-dimensional coordinate system. Establishing an analysis coordinate system based on the movement range and ensuring that the movement range is within the first quadrant of the analysis coordinate system can provide a basis for subsequent steps.

[0090] S2112. Obtain a projected X value, a nearest X value, a projected Y value, and a nearest Y value based on the movement range and the analysis coordinate system. Among them, the projected X value is the numerical value of the length of the projection of the movement range on the X-axis of the analysis coordinate system, the nearest X value is the numerical value of the shortest distance from the projection of the movement range on the X-axis of the analysis coordinate system to the origin of the analysis coordinate system, the projected Y value is the numerical value of the length of the projection of the movement range on the Y-axis of the analysis coordinate system, and the nearest Y value is the numerical value of the shortest distance from the projection of the movement range on the Y-axis of the analysis coordinate system to the origin of the analysis coordinate system.

[0091] It can be understood that when the movement range is projected onto the X-axis of the analysis coordinate system, the projection direction can be along the Y-axis direction of the analysis coordinate system. When the movement range is projected onto the Y-axis of the analysis coordinate system, the projection direction can be along the X-axis direction of the analysis coordinate system, but it is not limited to this. The method of obtaining the projected X value based on the movement range and the analysis coordinate system can be, for example, subtracting the X-axis coordinate value of the point on the line segment of the projection of the movement range on the X-axis of the analysis coordinate system that is closest to the origin from the X-axis coordinate value of the point on the line segment that is farthest from the origin, but it is not limited to this. The method of obtaining the nearest X value based on the movement range and the analysis coordinate system can be, for example, confirming the X-axis coordinate value of the point on the line segment of the projection of the movement range on the X-axis of the analysis coordinate system that is closest to the origin as the nearest X value, but it is not limited to this. The method of obtaining the projected Y value based on the movement range and the analysis coordinate system can be, for example, subtracting the Y-axis coordinate value of the point on the line segment of the projection of the movement range on the Y-axis of the analysis coordinate system that is closest to the origin from the Y-axis coordinate value of the point on the line segment that is farthest from the origin, but it is not limited to this. The method of obtaining the nearest Y value based on the movement range and the analysis coordinate system can be, for example, confirming the Y-axis coordinate value of the point on the line segment of the projection of the movement range on the Y-axis of the analysis coordinate system that is closest to the origin as the nearest Y value, but it is not limited to this. Obtaining the projected X value, the nearest X value, the projected Y value, and the nearest Y value based on the movement range and the analysis coordinate system can provide a basis for subsequent steps.

[0092] S2113. Divide the projected X value by m to obtain a step X value, and divide the projected Y value by m to obtain a step Y value. Among them, m is greater than or equal to 2.

[0093] It can be understood that setting m greater than or equal to 2 can ensure that the number of acquisition points obtained is greater than or equal to 2. Dividing the projected X value by m to obtain a step X value and dividing the projected Y value by m to obtain a step Y value can provide a basis for subsequent steps.

[0094] Exemplarily, assume m = 3, the projected X value = 9, and the projected Y value = 12. Then the step X value = 9 / 3 = 3, and the step Y value = 12 / 3 = 4.

[0095] S2114, step a: The value obtained by multiplying the step X value by n and adding the nearest X value is confirmed as the acquired X value, and the value obtained by multiplying the step Y value by n and adding the nearest Y value is confirmed as the acquired Y value. The coordinates formed by the acquired X value and the acquired Y value are confirmed as the acquisition points; where the initial value of n is equal to 1.

[0096] It can be understood that confirming the value obtained by multiplying the step X value by n and adding the nearest X value as the acquired X value, confirming the value obtained by multiplying the step Y value by n and adding the nearest Y value as the acquired Y value, and confirming the coordinates formed by the acquired X value and the acquired Y value as the acquisition points can provide a basis for subsequent steps.

[0097] Exemplarily, assume the step X value = 3, the nearest X value = 5, the step Y value = 4, the nearest Y value = 6, and n = 1. Then the acquired X value = 3 * 1 + 5 = 8, the acquired Y value = 4 * 1 + 6 = 10, and the coordinates of the acquisition point are (8, 10).

[0098] S2115: Determine whether the value obtained by adding 1 to the value of n is greater than m. If the value obtained by adding 1 to the value of n is less than or equal to m, then add 1 to the value of n in step a and repeat step a; if the value obtained by adding 1 to the value of n is greater than m, then do not repeat step a.

[0099] It can be understood that determining whether the value obtained by adding 1 to the value of n is greater than m is to determine whether m acquisition points have been obtained. If the value obtained by adding 1 to the value of n is less than or equal to m, it means that m acquisition points have not been obtained yet. If the value obtained by adding 1 to the value of n is greater than m, it means that m acquisition points have been obtained.

[0100] Exemplarily, assume m = 3 and the value of n in step a = 1. Then when passing through step S2115, 1 + 1 = 2 < 3. Then change the value of n in step a to 2 and repeat step a.

[0101] Assume m = 2 and the value of n in step a = 2. Then when passing through step S2115, 2 + 1 = 3 > 2, then jump out of the loop.

[0102] S212: Control the fixing part 20 to move the electrodes to each acquisition point respectively and stay at each acquisition point for a preset time period.

[0103] It can be understood that the preset time period can be 10 seconds, 30 seconds, etc., but is not limited thereto. The way for the control fixing part 20 to move the electrode to the acquisition point can be to control the rotation driving part 224 to drive the second rotating part 225 to rotate so as to drive the telescopic driving part 226 to rotate, and enable the position of the acquisition point to intersect with the extension line of the elongation driving direction of the telescopic driving part 226, and then control the telescopic driving part 226 to drive the fixed driving part 231 so that the fixed driving part 231 is located above the acquisition point, and then control the fixed driving part 231 to drive the electrode on the end of the power output rod of the fixed driving part 231 close to the user's scalp to contact the user's scalp with a preset force (which can be 1N, 1.2N, etc., but is not limited thereto), etc., but is not limited thereto. Controlling the fixing part 20 to move the electrode to each acquisition point respectively and stay at each acquisition point for a preset time period can provide a basis for subsequent steps.

[0104] S213, receive the electroencephalogram signal sent when the electrode stays at the acquisition point, and confirm the electroencephalogram signal as intensity information.

[0105] It can be understood that receiving the electroencephalogram signal sent when the electrode stays at the acquisition point and confirming the electroencephalogram signal as intensity information can provide a basis for subsequent steps.

[0106] S214, confirm all the intensity information and the acquisition points corresponding to the intensity information as regional intensity information.

[0107] It can be understood that confirming all the intensity information and the acquisition points corresponding to the intensity information as regional intensity information can provide a basis for subsequent steps.

[0108] S220, confirm all the regional intensity information as analysis information.

[0109] It can be understood that confirming all the regional intensity information as analysis information can provide a basis for subsequent steps.

[0110] S300, obtain electrode fixing position information based on the analysis information; wherein, the electrode fixing position information includes at least one contact position, and the contact position reflects the position of the electrode on the corresponding fixed area.

[0111] It can be understood that the way to obtain the electrode fixing position information based on the analysis information can be to judge the quality of the electroencephalogram signals at each position in the analysis information, confirm the position of the acquisition point corresponding to the electroencephalogram signal with better quality as the contact position, and confirm all the contact positions as the electrode fixing position information, or send the analysis information to a doctor and confirm the data returned after the doctor analyzes each electroencephalogram signal as the electrode fixing position information, etc., but is not limited thereto. Obtaining the electrode fixing position information based on the analysis information can provide a basis for subsequent steps.

[0112] In a possible implementation, please refer to Figure 7 , S300, obtaining electrode fixation position information based on the analysis information, including:

[0113] S310, determining whether the frequency of the electroencephalogram (EEG) signal corresponding to each acquisition point in the intensity information is within a preset frequency range, whether the amplitude is within a preset amplitude range, and whether the waveform is a continuous and stable waveform.

[0114] It can be understood that the preset frequency range can be 8 - 13 Hz, 13 - 30 Hz, etc., but is not limited thereto. The preset amplitude range can be 20 - 100 μV, 100 - 150 μV, etc., but is not limited thereto. Determining whether the waveform is a continuous and stable waveform can be to intercept the waveform of the EEG signal within a period of time and compare it with the standard waveform corresponding to the preset environment (for example, when the preset environment is that the user is normal, quiet, awake with eyes closed, the corresponding waveform is sinusoidal, and the rising and falling branches are smooth and symmetric), or to send the EEG signal to a doctor and receive the data returned by the doctor, etc., but is not limited thereto.

[0115] S320, if there is an EEG signal corresponding to an acquisition point in the intensity information whose frequency is within the preset frequency range, the amplitude is within the preset amplitude range, and the waveform is a continuous and stable waveform, then confirm the acquisition point corresponding to the EEG signal as a contact position.

[0116] It can be understood that if there is an EEG signal whose frequency is within the preset frequency range, the amplitude is within the preset amplitude range, and the waveform is a continuous and stable waveform, then the electrode can obtain a qualified EEG signal at this acquisition point, and confirming this acquisition point as a contact position can provide a basis for subsequent steps.

[0117] S330, confirm all the contact positions as electrode fixation position information.

[0118] It can be understood that confirming all the contact positions as electrode fixation position information can provide a basis for subsequent steps.

[0119] S400, controlling the fixing part 20 to fix the electrode based on the electrode fixation position information.

[0120] It can be understood that controlling the fixing part 20 to fix the electrode based on the electrode fixation position information can avoid abnormal EEG signals received by the electrode due to inappropriate contact positions between the electrode and the user's scalp, thus affecting the doctor's judgment, and can improve the problem of time-consuming and laborious electrode fixation by manual means.

[0121] In a possible implementation, please refer to Figure 7, S400, controls the fixing part 20 to fix the electrode based on the electrode fixed position information, including:

[0125] It can be understood that receiving the contact position selected by the doctor and confirming the contact position as the final position can ensure the reliability of the position where the electrode is fixed on the user's scalp.

[0126] S430, controls the fixing part 20 to fix the electrode based on the final position information.

[0127] It can be understood that the method of controlling the fixing part 20 to fix the electrode based on the final position information can be to control the rotation driving part 224 to drive the second rotating part 225 to rotate so as to drive the telescopic driving part 226 to rotate, and make the projection of the final position in the final position information in the direction along parallel to the user's neck and towards the user's leg be able to contact the final position on the user's scalp where the electrode needs to be fixed, then control the telescopic driving part 226 to drive the fixing driving part 231 to make the fixing driving part 231 located above the final position, and then control the fixing driving part 231 to drive the electrode on the end of the power output rod of the fixing driving part 231 close to the user's scalp to contact the user's scalp with a preset force, etc., but not limited to this. Controlling the fixing part 20 to fix the electrode based on the final position information can avoid the abnormal electroencephalogram signals received by the electrode due to the inappropriate contact position between the electrode and the user's scalp, thus affecting the doctor's judgment, and can improve the problem of time-consuming and laborious manual fixing of the electrode.
