Description

Technical Field

[0001] The present invention relates to acupoint bioelectric signal detection technology, and in particular to a test anxiety detection method and device based on acupoint bioelectric signal. Background Art

[0002] According to a study by the national mental health institution CEIBS, 61% of students have varying degrees of test anxiety, of which 26% have severe test anxiety. Students often experience anxiety when facing exams, which may manifest in a variety of psychological and physiological symptoms. Psychological symptoms include tension, fear, difficulty concentrating, memory loss, mood swings, lack of confidence, and excessive imagination. Physiologically, students may procrastinate, avoid exams, fidget, and have trembling hands and sweating. Physical symptoms may include insomnia, dizziness, headaches, nausea and vomiting, pale complexion, cold limbs, chest tightness and shortness of breath, loss of appetite, gastrointestinal discomfort, and frequent urination. In extreme cases, test anxiety may cause students to experience emotional tension, rapid heartbeat, rapid breathing, and high blood pressure in the examination room. Severe cases may lead to serious psychological disorders and suicidal behavior.

[0003] Therefore, people are in urgent need of testing their test anxiety so as to better understand their test anxiety and take appropriate measures to improve and regulate it, so as to achieve the goal of early detection, early intervention and early treatment. Currently, there are two methods for testing test anxiety: subjective testing and objective testing.

[0004] Among them, subjective testing refers to testing the test anxiety level of the subjects based on subjective questionnaires, self-recording forms, etc. Common test anxiety scales include the Sarason Test Anxiety Scale (TAS) and the Chinese version of the Test Anxiety Scale (PAF). These scales contain a series of questions, requiring the subjects to choose answers based on their actual situation, and then judge the anxiety level based on the scores. There are subjective scoring, difficulty in unifying the scoring standards, and easy to be affected by memory and other personal abilities. There may even be phenomena such as the subjects deliberately concealing their true feelings to cater to the intentions of the examiner. Therefore, this detection method cannot avoid its inherent shortcomings of low validity and reliability, and cannot achieve real-time dynamic detection.

[0005] Objective testing refers to the use of instruments, equipment and other tools to test the psychological, physiological and biochemical parameters of the human body. It can be divided into physiological testing equipment and imaging testing equipment.

[0006] In terms of physiological testing equipment, although the heart rate variability analyzer can detect heart rate-related indicators, individual differences in basic heart rate, daily exercise habits, and small body movements during testing can interfere with the measurement results, resulting in limited accuracy. Electrocardiographs and sphygmomanometers can only reflect the electrophysiological activity of the heart and blood pressure conditions, but test anxiety causes many physiological changes that they cannot fully cover, making it difficult to accurately determine the degree of anxiety.

[0007] In terms of imaging testing equipment, functional magnetic resonance imaging (fMRI) and positron emission tomography (PET) are not only expensive to purchase and operate, but also require professional technicians to operate, and the process is cumbersome. The radioactivity of PET makes it not frequently used for general test anxiety testing. The basic differences in EEG activity between individuals are huge, and the correlation between its waveform changes and anxiety is complex. It is difficult for non-professionals to accurately analyze and interpret it, which is not conducive to widespread promotion.

[0008] In summary, the existing technology lacks scientific, accurate and efficient test anxiety detection technology and needs innovation. Summary of the invention

[0009] The purpose of the present invention is to overcome the above-mentioned problems and provide a test anxiety detection method based on acupoint bioelectric signals. The test anxiety detection method determines whether anxiety exists by detecting changes in acupoint electrical signals of the human body, which is more scientific, accurate and efficient.

[0010] Another object of the present invention is to provide a test anxiety detection device based on acupoint bioelectric signals.

[0011] The purpose of the present invention is achieved through the following technical solutions:

[0012] A method for detecting test anxiety based on acupuncture bioelectric signals, comprising the following steps:

[0013] (1) placing the acupoint signal collection terminal on the acupoint surface of the user;

[0014] (2) collecting bio-analog signals of a plurality of acupoints of the user through the acupoint signal collection terminal, and obtaining a plurality of bio-digital signals according to the plurality of bio-analog signals; the plurality of bio-digital signals correspond to the plurality of acupoints one by one;

[0015] (3) calling a pre-stored acupoint test anxiety database, and obtaining a weight ratio factor corresponding to each acupoint from the preset acupoint test anxiety database;

[0016] (4) processing the multiple biological digital signals in combination with the weighted proportional factors of each acupoint to obtain the test anxiety state value;

[0017] (5) Obtaining a test anxiety threshold value from the acupoint test anxiety database, and comparing the test anxiety state value with the test anxiety threshold value to obtain and output a test anxiety detection result.

[0018] (6) If the test anxiety state value is greater than or equal to the severe test anxiety threshold, a test anxiety reminder signal is issued to relieve the test anxiety and prevent accidents caused by excessive test anxiety.

[0019] In a preferred embodiment of the present invention, in step (3), the weight proportional factor of each acupoint is calculated as follows:

[0020] The system state electronic measuring instrument was used to act on the twelve original acupoints on the left and right sides of the body surface of the students with test anxiety and the eight eight meridian intersection acupoints to measure the bioelectric signal values ​​of the acupoints. The SPSS26.0 software was used for statistical analysis and the Spearman correlation analysis formula was used. A correlation study was conducted to obtain the acupoints and their correlation coefficients related to test anxiety:

[0021] The left Shenmen point is 0.285, the right Chongyang point is 0.331, the left Jinggu point is 0.305, the right Jinggu point is 0.320, the left Zulinqi point is 0.304, the left Taibai point is 0.283, the left Qiuxu point is 0.265, the right Gongsun point is 0.332, the left Taixi point is 0.298, the left Lieque point is 0.270, the left Neiguan point is 0.275, the left Zhaohai point is 0.271, the right Yangchi point is 0.290, the left Shenmai point is 0.367, and the right Shenmai point is 0.296;

[0022] According to the correlation coefficient of each acupoint, the weight ratio factor of each acupoint can be calculated:

[0023] sumLeft Shenmen+Right Chongyang+Right Shenmai;

[0024] n is a meridian point;

[0025]

[0026] In a preferred embodiment of the present invention, in step (5), the test anxiety threshold comprises a mild test anxiety threshold, a moderate test anxiety threshold and a severe test anxiety threshold;

[0027] If the test anxiety state value is less than the mild test anxiety threshold, the test result indicating that the current state is normal is output, and the test anxiety state continues to be detected; if the test anxiety state value is greater than or equal to the mild test anxiety threshold, the test result indicating that the current state is test anxiety is output, and a reminder signal is issued.

[0028] By continuing to detect the test anxiety state when the test anxiety state value is less than the mild test anxiety threshold, it is helpful to ensure continuous monitoring and evaluation of the test anxiety state of the test subject; by outputting a fast-paced, highly stimulating audio signal when the test anxiety state value is greater than or equal to the mild test anxiety threshold but less than the moderate test anxiety threshold, the degree of anxiety awakening is increased; by outputting a slow-paced, less stimulating, and more soothing audio signal when the test anxiety state value is greater than or equal to the severe test anxiety threshold, the test anxiety is relieved, and at the same time, the test subject or other people in the same environment as the test subject are warned, the impact on the student's mentality caused by excessive anxiety is reduced, and at the same time, a risk warning of the severity of psychosomatic problems caused by excessive anxiety is provided, effectively preventing accidents caused by excessive test anxiety.

[0029] Further, if the current test anxiety state value is greater than or equal to the mild test anxiety threshold value but less than the moderate test anxiety threshold value, the detection result of mild test anxiety is output and displayed, and the sounder or buzzer or user terminal device is controlled by the warning module to emit a reminder sound at a first decibel value; otherwise, the current test anxiety state value is compared with the severe test anxiety threshold value;

[0030] If the current test anxiety state value is greater than or equal to the moderate test anxiety threshold but less than the severe test anxiety threshold, the detection result of moderate test anxiety is output and displayed, and the sounder or buzzer or user-end device is controlled by the warning module to emit a reminder sound at a second decibel value; otherwise, while outputting and displaying the detection result of severe test anxiety, the sounder or buzzer or user-end device is controlled by the warning module to emit a reminder sound at a third decibel value, and the vibrator or user-end device is controlled to enter a vibration state; the first decibel value is greater than the second decibel value, and the second decibel value is greater than the third decibel value.

[0031] By dividing the test anxiety status values ​​into levels and providing reminders, different signal reminders can be provided at different levels of test anxiety, thereby improving the rationality of the layout, providing better warnings to the test subjects and their caregivers, and better avoiding accidents.

[0032] A test anxiety detection device based on acupuncture bioelectric signals comprises an acupuncture signal acquisition terminal and an intelligent processing terminal. The acupuncture signal acquisition terminal is provided with multiple terminals and all are electrically connected to the intelligent processing terminal. The intelligent processing terminal comprises a controller, a display and a power supply. The controller is electrically connected to the display and the power supply respectively.

[0033] In a preferred embodiment of the present invention, the intelligent processing terminal further comprises an alarm device, which is electrically connected to the controller. By adding an alarm device to warn the test taker and related persons, it is helpful to reduce the occurrence of accidents caused by test anxiety.

[0034] Furthermore, the alarm device is one or more of a vibrator, a speaker, and a warning light.

[0035] In a preferred embodiment of the present invention, a Bluetooth module and / or a GSM module are integrated on the controller. By adding a Bluetooth module and / or a GSM module, it is advantageous to send the test anxiety test result of the test subject to personnel related to the test subject, which can better avoid the occurrence of accidents caused by test anxiety.

[0036] In a preferred embodiment of the present invention, the intelligent processing terminal further comprises a housing, wherein the controller, display and power supply are all arranged in the housing, and a plurality of function keys are arranged on the housing, through which all detection operations can be controlled.

[0037] Furthermore, the acupoint signal collection terminal is connected to the controller of the intelligent processing terminal through a wire, and the side wall of the shell is provided with a storage groove for storing the acupoint signal collection terminal.

[0038] Furthermore, an automatic wire-reeling mechanism for automatically winding up the wire is provided in the housing, and the automatic wire-reeling mechanism includes a wire-reeling wheel and a wire-reeling driving mechanism, and the wire-reeling wheel is rotatably connected to a mounting seat through a wire-reeling rotating shaft, and the mounting seat is fixedly arranged in the housing; one end of the wire is fixedly connected to the wire-reeling wheel, and the other end of the wire is fixedly connected to the acupuncture point signal collection end; the wire-reeling driving mechanism includes a wire-reeling driving motor and a wire-reeling transmission assembly, and the wire-reeling driving motor is fixedly arranged in the housing, and the wire-reeling driving motor is electrically connected to the controller, and the wire-reeling transmission assembly includes a synchronous belt and a pulley, and the synchronous belt and the pulley are connected between the wire-reeling driving motor and the wire-reeling rotating shaft to realize power transmission. Through the above structure, under the drive of the wire-reeling driving motor, the wire-reeling wheel can rotate in the corresponding direction, so that the wire is wound on the wire-reeling wheel, and automatic wire-reeling is realized.

[0039] Furthermore, the wire-taking transmission assembly further comprises a transmission shaft, which is connected to the wire-taking drive motor through a coupling; the synchronous belt and the pulley are provided in multiple groups, and the same group of pulleys is provided with two pulleys, one of the pulleys in the same group is coaxially arranged on the transmission shaft, and the other pulley in the same group is arranged on the wire-taking rotating shaft through a one-way bearing, and the pulley is connected to the two pulleys in the corresponding group;

[0040] In the line-reeling state, the one-way bearing transmits the power on the corresponding pulley to the line-reeling shaft, and in the line-releasing state, the one-way bearing disconnects the power connection between the corresponding pulley and the line-reeling shaft.

[0041] Through the above structure, one motor can be shared to complete multiple groups of wire-reeling operations, which is conducive to simplifying the structure and reducing costs. Furthermore, by setting a one-way bearing, when winding the wire, the one-way bearing is locked, so that the power on the corresponding pulley is transmitted to the wire-reeling shaft to complete the wire-reeling work; when releasing the wire, the inner ring and the outer ring of the one-way bearing rotate relative to each other, thereby disconnecting the power connection between the corresponding pulley and the wire-reeling shaft, and performing a separate wire-reeling work without affecting other wire-reeling wheels, which is very clever.

[0042] Furthermore, the automatic wire-winding mechanism further comprises an in-place disconnection structure, which comprises a mounting shaft, a guide wheel assembly, a disconnection fork, a reset spring and a limiter;

[0043] The installation shaft is fixedly connected to the installation seat, and the axis of the installation shaft is parallel to the axis of the take-up shaft;

[0044] The guide wheel assembly comprises two semi-guide wheels formed by dividing a V-shaped guide wheel from a central plane perpendicular to the axis, the two semi-guide wheels are rotatably connected to the mounting shaft, and a wire groove with a V-shaped cross section and variable width is formed between the two semi-guide wheels; a disconnecting drive section is provided on the conductor, and the size of the disconnecting drive section is larger than the size of the conductor; a limiting ring for limiting one of the semi-guide wheels is fixedly provided on the mounting shaft;

[0045] The disconnecting fork comprises a fork body and a fork portion, wherein the fork body is slidably sleeved on the mounting shaft, and the fork portion is provided with two forks, both extending in the direction of the one-way bearing, and the two fork portions are respectively located on both sides of the one-way bearing;

[0046] The return spring is slidably mounted on the mounting shaft, and the two ends of the return spring are respectively pressed against the disconnection fork and the mounting seat; the end of the disconnection fork away from the return spring is pressed against the other half guide wheel;

[0047] A transverse sliding structure is provided between the one-way bearing and the corresponding pulley, and the transverse sliding structure comprises a transverse sliding groove arranged on the pulley and a transverse sliding rail arranged on the one-way bearing; the limiter is used to limit the transverse movement of the pulley corresponding to the one-way bearing;

[0048] The axis of the one-way bearing is longer than the axis of the corresponding pulley. The inner surface of the inner ring of the one-way bearing is provided with an annular disconnecting groove and a power transmission groove. The annular disconnecting groove is provided and multiple are evenly arranged along the axis direction; the power transmission groove runs through the inner surface of the inner ring of the one-way bearing, and the extension direction of the power transmission groove is parallel to the axis of the one-way bearing; the take-up shaft is provided with multiple power transmission bosses evenly arranged along the axis direction;

[0049] In the power transmission state, the power transmission boss is located in the power transmission groove, and the conducting wire is located in the V-shaped wire groove. At this time, the width of the V-shaped wire groove is the smallest; in the power disconnection state, the power transmission boss is located in the annular disconnection groove, and the disconnection drive section is located in the V-shaped wire groove. At this time, the width of the V-shaped wire groove is the largest, and the acupoint signal collection end is located in the corresponding storage groove.

[0050] The working principle of the above-mentioned in-place disconnection structure is:

[0051] After completing the detection work, it is necessary to retract the acupoint signal collection end and the wire. At this time, it is in the power transmission state. The power transmission boss of the wire-reeling shaft is located in the power transmission groove of the one-way bearing. Under the drive provided by the wire-reeling drive motor, the wire-reeling transmission assembly transmits power to the one-way bearing, and then the power transmission boss on the wire-reeling shaft drives the wire-reeling shaft to rotate, thereby driving the winding wheel to reel in the wire, and guiding the wire through two semi-guide wheels. At this time, the width of the V-shaped wire groove is the smallest.

[0052] At the tail end of the winding work, after the disconnection drive section on the guide line enters the V-shaped wire groove, due to the large size of the disconnection drive section, when the winding drive motor is pulled, the disconnection drive section will stretch out another half guide wheel (the width of the V-shaped wire groove becomes larger at this time), so that the other half guide wheel moves in the direction of the reset spring and pushes the disconnection fork, and then the disconnection fork shifts the one-way bearing through the fork part, so that the one-way bearing moves laterally relative to the corresponding pulley, and at the same time the reset spring is squeezed and deformed to store energy until the power transmission boss of the winding shaft is located in the annular disconnection groove of the one-way bearing, entering the power disconnection state, at this time the width of the V-shaped wire groove is the largest, and the acupoint signal collection end is stored in the corresponding storage groove. The advantage of this is that the winding wheel of this group can be disconnected from the power transmission chain without hindering the winding work of other winding wheels, not only realizing the sharing of a power, but more importantly, it can also realize separate winding without affecting the work of other winding wheels, which is very clever and suitable for occasions where the extension lengths of each acupoint signal collection end are different.

[0053] When it is necessary to pull out the acupoint signal collection end for collection work, the disconnecting drive section on the guide line will first leave the V-shaped wire groove. At the same time, the reset spring releases potential energy to restore deformation, driving the disconnecting fork to move in the direction of the other half guide wheel, and then the one-way bearing is moved by the fork part to perform a lateral reset movement relative to the corresponding pulley until the power transmission boss of the take-up shaft is located in the power transmission groove of the one-way bearing and returns to the power transmission state, so that the wire can be smoothly retracted when the line is taken up.

[0054] Furthermore, a plurality of wiring guide wheels are provided in the housing, which can not only change the direction of the wire, but also extend the length of the non-reeling portion of the wire to meet different needs.

[0055] Compared with the prior art, the present invention has the following beneficial effects:

[0056] 1. The present invention is based on the theory of acupuncture points in traditional Chinese medicine. It determines whether there is test anxiety and the test anxiety state by real-time detection of changes in electrical signals of acupuncture points, thereby ensuring a high correlation between parameters, reducing the influence of subjective factors, and improving system reliability. During detection, it is only necessary to align the acupuncture points and select the corresponding parameters before starting the detection, which is convenient for the test subject to use the detection himself, and is more scientific, accurate, and efficient.

[0057] 2. The present invention uses bioelectric signals on acupoints to conduct comprehensive analysis and judgment of multiple acupoints according to weight proportional factors of different acupoints, thereby improving the accuracy of test anxiety detection, and continuously collects bioelectric signals of acupoints to detect test anxiety in real time, which has higher real-time performance.

[0058] 3. Depending on the severity of the test anxiety, the device can provide different levels of reminder signals, including sound, light and vibration, to ensure that users or caregivers can notice abnormal conditions in time and relieve the anxiety of people who are in severe test anxiety.

[0059] 4. It solves the problems of existing mainstream detection technologies, such as high detection technology difficulty, complex equipment, difficult operation, and resistance from the test subjects. BRIEF DESCRIPTION OF THE DRAWINGS

[0068] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described below in conjunction with embodiments and drawings, but the embodiments of the present invention are not limited thereto.

[0069] See also Figure 1 The test anxiety detection method based on acupuncture bioelectric signals of this embodiment comprises the following steps:

[0070] (1) Place the acupoint signal acquisition terminal on the skin surface of the acupoint, and start the acquisition after the user's breathing becomes stable; specifically, the acupoint signal acquisition terminal and its acquisition principle can refer to the existing technology.

[0071] (2) The bio-analog signals of the multiple acupoints of the user are collected through the acupoint signal collection terminal, and multiple bio-digital signals are obtained according to the multiple bio-analog signals; the multiple bio-digital signals correspond to the multiple acupoints respectively.

[0072] The acupoint test anxiety database is pre-stored in the data storage module of the intelligent processing terminal, or the acupoint test anxiety data to be set can be entered and stored in the memory before or during the detection by means of touch input signals in the display of the intelligent processing terminal; or the acupoint test anxiety data to be set can be entered and stored in the data storage module of the intelligent processing terminal by means of key input before or during the detection, thereby forming an acupoint test anxiety database in the intelligent processing terminal.

[0073] (3) calling a pre-stored acupoint test anxiety database, and obtaining a weight proportional factor corresponding to each acupoint from the preset acupoint test anxiety database; wherein the weight proportional factor calculation method of each acupoint is:

[0074] The system state electronic measuring instrument was used to act on the twelve original acupoints on the left and right sides of the body surface of the students with test anxiety and the eight eight meridian intersection acupoints to measure the bioelectric signal values ​​of the acupoints. The SPSS26.0 software was used for statistical analysis and the Spearman correlation analysis formula was used. A correlation study was conducted to obtain the acupoints and their correlation coefficients related to test anxiety:

[0075] The left Shenmen point is 0.285, the right Chongyang point is 0.331, the left Jinggu point is 0.305, the right Jinggu point is 0.320, the left Zulinqi point is 0.304, the left Taibai point is 0.283, the left Qiuxu point is 0.265, the right Gongsun point is 0.332, the left Taixi point is 0.298, the left Lieque point is 0.270, the left Neiguan point is 0.275, the left Zhaohai point is 0.271, the right Yangchi point is 0.290, the left Shenmai point is 0.367, and the right Shenmai point is 0.296.

[0076] According to the correlation coefficient of each acupoint, the weight ratio factor of each acupoint can be calculated:

[0077] sum left shenmen + r right chongyang right shenmai;

[0078] n is a meridian point;

[0079]

[0080] (4) Multiple biological digital signals are combined with the weighted proportional factors of each acupoint to obtain the test anxiety state value.

[0081] (5) Obtaining a test anxiety threshold value from the acupoint test anxiety database, and comparing the test anxiety state value with the test anxiety threshold value to obtain and output a test anxiety detection result.

[0082] Furthermore, the test anxiety threshold includes a mild test anxiety threshold, a moderate test anxiety threshold and a severe test anxiety threshold.

[0083] If the test anxiety state value is less than the mild test anxiety threshold, the test result indicating that the current state is normal is output, and the test anxiety state continues to be detected; if the test anxiety state value is greater than or equal to the mild test anxiety threshold, the test result indicating that the current state is test anxiety is output, and a reminder signal is issued.

[0084] By continuing to detect the test anxiety state when the test anxiety state value is less than the mild test anxiety threshold, it is helpful to ensure continuous monitoring and evaluation of the test anxiety state of the test subject; by outputting a fast-paced, highly stimulating audio signal when the test anxiety state value is greater than or equal to the mild test anxiety threshold but less than the moderate test anxiety threshold, the degree of anxiety awakening is increased; by outputting a slow-paced, less stimulating, and more soothing audio signal when the test anxiety state value is greater than or equal to the severe test anxiety threshold, the test anxiety is relieved, and at the same time, the test subject or other people in the same environment as the test subject are warned, the impact on the student's mentality caused by excessive anxiety is reduced, and at the same time, a risk warning of the severity of psychosomatic problems caused by excessive anxiety is provided, effectively preventing accidents caused by excessive test anxiety.

[0085] Further, if the current test anxiety state value is greater than or equal to the mild test anxiety threshold but less than the moderate test anxiety threshold, the detection result of mild test anxiety is output and displayed, and the sounder or buzzer or user-end device is controlled by the warning module to emit a reminder sound at a first decibel value; otherwise, the current test anxiety state value is compared with the severe test anxiety threshold.

[0086] If the current test anxiety state value is greater than or equal to the moderate test anxiety threshold but less than the severe test anxiety threshold, the detection result of moderate test anxiety is output and displayed, and the sounder or buzzer or user-end device is controlled by the warning module to emit a reminder sound at a second decibel value; otherwise, while outputting and displaying the detection result of severe test anxiety, the sounder or buzzer or user-end device is controlled by the warning module to emit a reminder sound at a third decibel value, and the vibrator or user-end device is controlled to enter a vibration state; the first decibel value is greater than the second decibel value, and the second decibel value is greater than the third decibel value.

[0087] By dividing the test anxiety status values ​​into levels and providing reminders, different signal reminders can be provided at different levels of test anxiety, thereby improving the rationality of the layout, providing better warnings to the test subjects and their caregivers, and better avoiding accidents.

[0088] Specifically, the above-mentioned audio reminder signal complies with the safety and performance standards of the Technical Review Specifications for ECG Monitoring Products (2017 Edition).

[0089] Regarding the setting of sound types: Although the worry component of test anxiety is significantly negatively correlated with learning performance, the tension component of test anxiety is significantly positively correlated with learning performance. Moderate levels of anxiety arousal can better activate cognitive functions and learning performance. Moderate physiological arousal can promote test performance, that is, the more nervous an individual experiences, the better the test score. When test anxious individuals only show physical tension, it can promote learning performance. Therefore, in case of mild test anxiety, fast-paced and highly stimulating audio signals are output to increase the degree of arousal; in case of severe test anxiety, slow-paced and weakly stimulating audio signals are output to relieve test anxiety, such as the sound of waves, rain, birdsong, etc., to provide a sense of calm and relaxation.

[0090] Regarding the sound volume setting: the first decibel audio (mild test anxiety): set at 80-85 decibels. This decibel sound is loud and enhances the degree of awakening of test anxiety; the second decibel audio (moderate test anxiety): set at 70-75 decibels; the third decibel audio (severe test anxiety): set at 60-65 decibels. This decibel audio will not be too harsh or cause panic. It can relieve the test anxiety of the subjects while reminding their caregivers to take immediate action.

[0091] In addition, according to the IEC60601-1-8 standard, the audio frequency is set between 150Hz and 1000Hz, and is one of the four harmonics with the largest sound level. There are four frequency peaks, and the sound level difference between the four maximum frequency peaks is within 15dB; the high priority rise time (tr) and fall time (tf) are 20ms, and the medium and low priorities are 40ms, both of which are intermittent sounds. The high priority pulse interval (ts) is 100ms, and the actual interval time is ts-45ms, i.e. 55ms; the medium priority pulse interval (ts) is 200ms, and the actual interval time = ts-90ms, i.e. 110ms; the low priority pulse interval (ts) is 500ms, only one signal is set, and the actual interval time is not set.

[0092] See also Figure 2-3 The test anxiety detection device based on acupuncture bioelectric signals of this embodiment includes an acupuncture signal acquisition terminal 1 and an intelligent processing terminal. The acupuncture signal acquisition terminal 1 is provided with multiple terminals and all are electrically connected to the intelligent processing terminal (the acupuncture signal acquisition terminal 1 of this embodiment is provided with three terminals, of course, it can also be more). The intelligent processing terminal includes a housing 2, a controller 3, a display 4 and a power supply 5. The controller 3, the display 4 and the power supply 5 are all arranged in the housing 2, and the controller 3 is electrically connected to the display 4 and the power supply 5 respectively. Specifically, the acupuncture signal acquisition terminal 1 includes an electrode probe and a patch. The electrode probe is arranged on the surface of the patch for direct contact with the skin. The patch is used to stick double-sided tape, and is adhered to the skin through the double-sided tape, or other structures that can fix the acupuncture signal acquisition terminal 1 on the corresponding acupuncture point are adopted. The acquisition method of the acupuncture signal acquisition terminal 1 can adopt the existing technology, such as other related technologies such as CN108158572A.

[0093] The working principle of the test anxiety detection device based on acupuncture bioelectric signals of this embodiment is as follows:

[0094] First, multiple acupoint signal acquisition terminals are attached to the corresponding acupoints of the subject, wherein the selection of acupoints can be obtained according to experiments, by selecting fifteen acupoints that are highly related to test anxiety from the twelve original acupoints and eight meridian intersection acupoints in the human body: left Shenmen acupoint, right Chongyang acupoint, left Jinggu acupoint, right Jinggu acupoint, left Linqi acupoint, left Taibai acupoint, left Qiuxu acupoint, right Gongsun acupoint, left Taixi acupoint, left Lieque acupoint, left Neiguan acupoint, left Zhaohai acupoint, right Yangchi acupoint, left Shenmai acupoint, right Shenmai acupoint (the number of acupoints can be 3-15 according to actual needs). Then, turn on the working power supply, and each acupoint signal acquisition terminal will detect the best bio-simulation signal of the corresponding acupoint, and input the best bio-simulation signal into the data acquisition module. The data acquisition module amplifies and filters the bio-simulation signal in turn to obtain a simulation signal that can be input into the intelligent processing terminal. The intelligent processing terminal performs digital-to-analog conversion on the analog signals continuously input by the data acquisition module to obtain biological digital signals corresponding to the analog signals of each acupoint. The size of the biological digital signals can reflect the test anxiety state to a certain extent.

[0095] See also Figure 4-6 The acupuncture point signal acquisition terminal 1 is connected to the controller of the intelligent processing terminal through a wire 6. The side wall of the shell 2 is provided with a storage slot 2-1 for storing the acupuncture point signal acquisition terminal 1. The shell 2 is provided with a plurality of function buttons, and all detection operations can be controlled by the plurality of function buttons.

[0096] See also Figure 4-6 The housing 2 is provided with an automatic wire-reeling mechanism for automatically winding the wire 6, the automatic wire-reeling mechanism includes a wire-reeling wheel 7 and a wire-reeling driving mechanism, the wire-reeling wheel 7 is rotatably connected to a mounting seat 9 through a wire-reeling rotating shaft 8, and the mounting seat 9 is fixedly arranged in the housing 2; one end of the wire 6 is fixedly connected to the wire-reeling wheel 7, and the other end of the wire 6 is fixedly connected to the acupuncture signal acquisition terminal 1; the wire-reeling driving mechanism includes a wire-reeling driving motor 10 and a wire-reeling transmission assembly, the wire-reeling driving motor 10 is fixedly arranged in the housing 2, and the wire-reeling transmission assembly includes a synchronous belt 11 and a pulley 12, and the synchronous belt 11 and the pulley 12 are connected between the wire-reeling driving motor 10 and the wire-reeling rotating shaft 8 to realize power transmission. Through the above structure, under the drive of the wire-reeling driving motor 10, the wire-reeling wheel 7 can rotate in the corresponding direction, so that the wire 6 is wound on the wire-reeling wheel 7, and automatic wire-reeling is realized.

[0097] Specifically, the length of the wire 6 of this embodiment can be adaptively set according to actual needs to meet the needs of most people, with the aim of reaching the main acupuncture points of the human body; of course, multiple different product models can also be divided according to different height ranges, and different models have different wire lengths to adapt to people of different heights.

[0098] See also Figure 4-6 The wire-taking transmission assembly also includes a transmission shaft 13, which is connected to the wire-taking drive motor 10 through a coupling; the synchronous belt 11 and the pulley 12 are provided with multiple groups, and the same group of pulleys 12 is provided with two pulleys 12, one of the pulleys 12 in the same group is coaxially arranged on the transmission shaft 13, and the other pulley 12 in the same group is arranged on the wire-taking shaft 8 through a one-way bearing 14, and the pulley 12 is connected to the two pulleys 12 of the corresponding group; in the wire-taking state, the one-way bearing 14 transmits the power on the corresponding pulley 12 to the wire-taking shaft 8, and in the wire-releasing state, the one-way bearing 14 disconnects the power connection between the corresponding pulley 12 and the wire-taking shaft 8.

[0099] Through the above structure, one motor can be shared to complete multiple groups of winding operations, which is conducive to simplifying the structure and reducing costs. Furthermore, by setting a one-way bearing 14, when winding, the one-way bearing 14 is locked, so that the power on the corresponding pulley 12 is transmitted to the winding shaft 8 to complete the winding work; when releasing the line, the inner ring and the outer ring of the one-way bearing 14 rotate relative to each other, thereby disconnecting the power connection between the corresponding pulley 12 and the winding shaft 8, and performing a separate winding work without affecting other winding wheels 7, which is very clever.

[0100] See also Figure 7-11 The automatic wire-winding mechanism also includes an in-place disconnection structure, which includes a mounting shaft 15, a guide wheel group, a disconnection fork 16, a reset spring 17 and a limiter 18; the mounting shaft 15 is fixedly connected to the mounting seat 9, and the axis of the mounting shaft 15 is parallel to the axis of the wire-winding rotating shaft 8; the guide wheel group includes two semi-guide wheels 19 formed by dividing a V-shaped guide wheel from a central plane perpendicular to the axis, and the two semi-guide wheels 19 are rotatably connected to the mounting shaft 15, and a wire groove with a V-shaped cross-section and variable width is formed between the two semi-guide wheels 19; a disconnection drive section 20 is provided on the conductor 6, and the size of the disconnection drive section 20 is larger than that of the conductor 6 size; a limiting ring 21 for limiting one of the semi-guide wheels 19 is fixedly provided on the mounting shaft 15; the disconnecting fork 16 comprises a fork body and a fork portion 16-1, the fork body is slidably mounted on the mounting shaft 15, the fork portion 16-1 is provided with two and both extend in the direction of the one-way bearing 14, and the two fork portions 16-1 are respectively located on both sides of the one-way bearing 14; the reset spring 17 is slidably mounted on the mounting shaft 15, and the two ends of the reset spring 17 are respectively pressed against the disconnecting fork 16 and the mounting seat 9; the end of the disconnecting fork 16 away from the reset spring 17 is pressed against the other semi-guide wheel 19.

[0101] A transverse sliding structure is provided between the one-way bearing 14 and the corresponding pulley 12, and the transverse sliding structure includes a transverse sliding groove 12-1 arranged on the pulley 12 and a transverse sliding rail 14-1 arranged on the one-way bearing 14; the limiter 18 is used to limit the transverse movement of the pulley 12 corresponding to the one-way bearing 14; the axis of the one-way bearing 14 is longer than the axis of the corresponding pulley 12, and the inner surface of the inner ring of the one-way bearing 14 is provided with an annular disconnecting groove 14-2 and a power transmission groove 14-3, and the annular disconnecting groove 14-2 is provided and multiple are evenly arranged along the axial direction; the power transmission groove 14-3 runs through the inner surface of the inner ring of the one-way bearing 14, and the extension direction of the power transmission groove 14-3 is parallel to the axis of the one-way bearing 14; the winding shaft 8 is provided with multiple power transmission bosses 8-1 evenly arranged along the axial direction.

[0102] In the power transmission state, the power transmission boss 8-1 is located in the power transmission groove 14-3, and the conductor 6 is located in the V-shaped wire groove. At this time, the width of the V-shaped wire groove is the smallest; in the power disconnection state, the power transmission boss 8-1 is located in the annular disconnection groove 14-2, and the disconnection drive node 20 is located in the V-shaped wire groove. At this time, the width of the V-shaped wire groove is the largest, and the acupoint signal acquisition terminal 1 is located in the corresponding storage groove 2-1.

[0103] See also Figure 7-11 The working principle of the above-mentioned in-place disconnection structure is:

[0104] After completing the detection work, it is necessary to retract the acupuncture point signal collection terminal 1 and the wire 6. At this time, it is in the power transmission state. The power transmission boss 8-1 of the wire-reeling shaft 8 is located in the power transmission groove 14-3 of the one-way bearing 14. Under the drive provided by the wire-reeling drive motor 10, the wire-reeling transmission assembly transmits the power to the one-way bearing 14, and then the power transmission boss 8-1 on the wire-reeling shaft 8 drives the wire-reeling shaft 8 to rotate, thereby driving the winding wheel to reel in the wire 6, and guiding the wire 6 through the two semi-guide wheels 19. At this time, the width of the V-shaped wire groove is the smallest, such as Figure 8 .

[0105] At the tail end of the winding operation, after the disconnecting drive section 20 on the guide line enters the V-shaped wire groove, due to the large size of the disconnecting drive section 20, when the wire winding drive motor 10 pulls, the disconnecting drive section 20 will push outward the other half guide wheel 19 (at this time, the width of the V-shaped wire groove becomes larger), so that the other half guide wheel 19 moves in the direction of the reset spring 17 and pushes the disconnecting fork 16, and then the disconnecting fork 16 shifts the one-way bearing 14 through the fork portion 16-1, so that the one-way bearing 14 moves laterally relative to the corresponding pulley 12, and at the same time the reset spring 17 is squeezed and deformed to store energy, until the power transmission boss 8-1 of the wire winding shaft 8 is located in the annular disconnecting groove 14-2 of the one-way bearing 14, and enters the power disconnection state. At this time, the width of the V-shaped wire groove is the largest, as shown in FIG. Fig. 9 The acupuncture point signal collection terminal 1 is stored in the corresponding storage slot 2-1. The advantage of this is that the winding wheel of the group can be disconnected from the power transmission chain without hindering the winding work of other winding wheels. Not only can the power be shared, but more importantly, it can also be wound separately without affecting the work of other winding wheels. It is very clever and suitable for occasions where the extension lengths of each acupuncture point signal collection terminal 1 are different.

[0106] When it is necessary to pull out the acupoint signal collection terminal 1 for collection work, the disconnecting drive section 20 on the guide line will first leave the V-shaped wire groove. At the same time, the reset spring 17 releases potential energy to restore deformation, driving the disconnecting fork 16 to move in the direction of the other half guide wheel 19, and then through the fork part 16-1, the one-way bearing 14 is shifted to perform a lateral reset movement relative to the corresponding pulley 12 until the power transmission boss 8-1 of the winding shaft 8 is located in the power transmission groove 14-3 of the one-way bearing 14, and returns to the power transmission state, so that the wire 6 can be smoothly retracted when winding.

[0107] See also Figure 5 A plurality of wiring guide wheels 22 are provided in the housing 2. The wiring guide wheels 22 can not only change the direction of the wire 6, but also extend the length of the non-reeling portion of the wire 6 to meet different needs.

[0108] Specifically, the intelligent processing terminal further includes an alarm device, which is electrically connected to the controller 3. By adding an alarm device to warn the test subject and related persons, it is helpful to reduce the occurrence of accidents caused by test anxiety.

[0109] Furthermore, the alarm device is one or more of a vibrator, a speaker, and a warning light.

[0110] When the test anxiety detection result shows that the subject's current state is test anxiety, the controller will control the warning module to make a sound and / or light up a reminder; when the test anxiety detection result shows that the subject's current state is normal, that is, it is not in a test anxiety state, the controller will not control the warning module to make a sound or light up a reminder, that is, the warning module is in standby mode at this time.

[0111] The vibrator in this embodiment can be directly connected to the controller through a wire to achieve signal connection, or can be connected to the controller through a Bluetooth connection. When the vibrator is connected to the controller through a Bluetooth connection, the vibrator and the controller can be separately set and worn or carried by the subject and / or a person related to the subject, which can enhance the reminder effect and have a better reminder effect.

[0112] Specifically, a Bluetooth module and / or a GSM module are integrated on the controller 3. By adding a Bluetooth module and / or a GSM module, it is beneficial to send the test anxiety detection result of the test subject to personnel related to the test subject, which can better avoid the occurrence of accidents caused by test anxiety.

[0113] The above is a preferred embodiment of the present invention, but the embodiment of the present invention is not limited to the above content. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principles of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
