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 detection devices, although a heart rate variability analyzer can detect heart rate-related indicators, factors such as the individual's different basal heart rates, differences in daily exercise habits, and minor body movements during detection can all interfere with the measurement results, resulting in limited accuracy. Electrocardiographs and sphygmomanometers can only reflect the cardiac electrophysiological activities and blood pressure conditions, but there are numerous physiological changes caused by test anxiety, which they cannot comprehensively cover and are difficult to accurately determine the degree of anxiety.

[0007] In terms of imaging detection devices, functional magnetic resonance imaging (fMRI) and positron emission tomography (PET) not only have high equipment purchase and operation costs, but also require professional technical personnel for operation, and the process is cumbersome. The radioactivity of PET makes it impossible to be frequently used for ordinary test anxiety detection. The basic differences in electroencephalogram (EEG) activities among individuals are extremely large, and the relationship between its waveform changes and anxiety is complex, making it difficult for non-professionals to accurately analyze and interpret, which is not conducive to wide promotion.

[0008] In summary, there is a lack of scientific, accurate, and efficient test anxiety detection technologies in the existing technologies, and innovation is needed. Summary of the Invention

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

[0010] Another purpose 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 test anxiety detection method based on acupoint bioelectric signals includes the following steps:

[0013] (1) Place the acupoint signal acquisition end on the surface of the user's acupoints;

[0014] (2) Collect the bio-simulation signals of multiple acupoints of the user through the acupoint signal acquisition end, and process multiple bio-digital signals based on the multiple bio-simulation signals; the multiple bio-digital signals correspond to the multiple acupoints one by one;

[0015] (3) Call the pre-stored acupoint test anxiety database, and obtain the weight ratio factors corresponding to each acupoint from the preset acupoint test anxiety database;

[0016] (4) Process the multiple bio-digital signals in combination with the weight ratio factors of each acupoint to obtain a test anxiety state value;

[0017] (5) Obtain the test anxiety threshold from the meridian point test anxiety database, compare the size of the test anxiety state value and the test anxiety threshold, and obtain and output the test anxiety detection result.

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

[0019] A preferred solution of the present invention is that in step (3), the calculation method of the weight ratio factor of each meridian point is as follows:

[0020] Use a system state electronic measuring instrument to act on the twelve yuan-source points and eight confluence points of the eight extra meridians on the left and right sides of the body surface of students with test anxiety, measure the bioelectric signal values of their meridian points, perform statistical analysis with SPSS26.0 software, and use the Spearman correlation analysis formula Conduct a correlation study to obtain the meridian points related to test anxiety and their correlation coefficients:

[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 coefficients of each meridian point, the weight ratio factors of each meridian point can be calculated:

[0023] sum of left Shenmen + right Chongyang + right Shenmai;

[0024] n is the meridian point;

[0025]

[0026] A preferred solution of the present invention is that in step (5), the test anxiety threshold includes 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, output a detection result indicating that the current state is normal, and continue to detect the test anxiety state; if the test anxiety state value is greater than or equal to the mild test anxiety threshold, output a detection result indicating that the current state is test anxiety and send a reminder signal.

[0028] By continuously detecting the test anxiety state when the test anxiety state value is less than the mild test anxiety threshold, it is beneficial to ensure the continuous monitoring and evaluation of the test anxiety state of the test taker; by outputting an audio signal with a fast rhythm and strong stimulation when the test anxiety state value is greater than or equal to the mild test anxiety threshold and less than the moderate test anxiety threshold, the arousal degree of anxiety is increased; by outputting an audio signal with a slow rhythm, weak stimulation and relatively soothing when the test anxiety state value is greater than or equal to the severe test anxiety threshold, the test anxiety emotion is relieved, and at the same time, the test taker or others in the same environment as the test taker are warned, reducing the impact on the student's mentality caused by excessive anxiety, and at the same time providing a risk warning of the severity of psychosomatic problems caused by excessive anxiety, 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 and less than the moderate test anxiety threshold, the detection result of mild test anxiety is output and displayed, and the warning module is used to control the sound generator or buzzer or client device to emit a reminder sound at the first decibel value; otherwise, compare the size of the current test anxiety state value with the severe test anxiety threshold;

[0030] If the current test anxiety state value is greater than or equal to the moderate test anxiety threshold and less than the severe test anxiety threshold, the detection result of moderate test anxiety is output and displayed, and the warning module is used to control the sound generator or buzzer or client device to emit a reminder sound at the second decibel value; otherwise, while outputting and displaying the detection result of severe test anxiety, the warning module is used to control the sound generator or buzzer or client device to emit a reminder sound at the third decibel value, and control the vibrator or client device to enter the 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 state value into levels for reminder, different signal reminders are realized at different levels of test anxiety, improving the rationality of the layout, and being able to better warn the test taker and their caregivers, and being able to better avoid accidents.

[0032] A test anxiety detection device based on acupoint bioelectric signals, comprising an acupoint signal acquisition end and an intelligent processing terminal. A plurality of acupoint signal acquisition ends are provided and are all electrically connected to the intelligent processing terminal. The intelligent processing terminal includes a controller, a display and a power supply. The controller is electrically connected to the display and the power supply respectively.

[0033] A preferred solution of the present invention, wherein the intelligent processing terminal further includes a warning device, and the warning device is electrically connected to the controller. By adding a warning device, warning the test taker and relevant persons is beneficial to reducing the occurrence of accidents caused by test anxiety.

[0034] Furthermore, the warning device is one or more of a vibrator, a loudspeaker, 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 the Bluetooth module and / or the GSM module, it is beneficial to send the test anxiety detection results of the test taker to the personnel related to the test taker, and 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 includes a housing, the controller, the display, and the power supply are all arranged in the housing, and a plurality of function keys are arranged on the housing, and all operations of the detection can be controlled through the plurality of function keys.

[0037] Furthermore, the acupoint signal acquisition end is connected to the controller of the intelligent processing terminal through a wire, and a storage groove for storing the acupoint signal acquisition end is arranged on the side wall of the housing.

[0038] Furthermore, an automatic wire winding mechanism for automatically winding the wire is arranged in the housing. The automatic wire winding mechanism includes a wire winding wheel and a wire winding driving mechanism. The wire winding wheel is rotatably connected to a mounting seat through a wire winding rotating shaft, and the mounting seat is fixedly arranged in the housing; one end of the wire is fixedly connected to the wire winding wheel, and the other end of the wire is fixedly connected to the acupoint signal acquisition end; the wire winding driving mechanism includes a wire winding driving motor and a wire winding transmission assembly. The wire winding driving motor is fixedly arranged in the housing and is electrically connected to the controller. The wire winding transmission assembly includes a synchronous belt and belt pulleys. The synchronous belt and the belt pulleys are connected between the wire winding driving motor and the wire winding rotating shaft to achieve power transmission. Through the above structure, driven by the wire winding driving motor, the wire winding wheel can rotate in the corresponding direction, so as to wind the wire on the wire winding wheel and realize automatic wire winding.

[0039] Furthermore, the wire winding transmission assembly further includes a transmission shaft, and the transmission shaft is connected to the wire winding driving motor through a coupling; there are multiple groups of the synchronous belts and the belt pulleys. Each group of belt pulleys has two belt pulleys. One of the belt pulleys in the same group is coaxially arranged on the transmission shaft, and the other belt pulley in the same group is arranged on the wire winding rotating shaft through a one-way bearing. The belt pulley is connected to the two belt pulleys in the corresponding group;

[0040] In the wire winding state, the one-way bearing transmits the power on the corresponding belt pulley to the wire winding rotating shaft. In the wire unwinding state, the one-way bearing disconnects the power connection between the corresponding belt pulley and the wire winding rotating shaft.

[0041] With the above structure, a single motor can be shared to complete multiple sets of wire winding operations, which is beneficial to simplifying the structure and reducing costs. Further, by providing a one-way bearing, during wire winding, the one-way bearing is locked, so that the power on the corresponding pulley is transmitted to the wire winding rotating shaft to complete the wire winding work; during wire unwinding, 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 winding rotating shaft and performing independent wire unwinding work without affecting other wire winding wheels, which is very ingenious.

[0042] Further, the automatic wire winding mechanism further includes a position-reached disconnection structure, which includes a mounting shaft, a guide wheel set, a disconnection fork, a return spring, and a limiting member;

[0043] The mounting shaft is fixedly connected to the mounting seat, and the axis of the mounting shaft is parallel to the axis of the wire winding rotating shaft;

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

[0045] The disconnection fork includes a fork body and fork parts. The fork body is slidably sleeved on the mounting shaft, and there are two fork parts which both extend towards the direction of the one-way bearing, and the two fork parts are respectively located on both sides of the one-way bearing;

[0046] The return spring is slidably sleeved on the mounting shaft, and both ends of the return spring respectively abut against the disconnection fork and the mounting seat; the end of the disconnection fork away from the return spring abuts against the other semi-guide wheel;

[0047] A transverse sliding structure is provided between the one-way bearing and the corresponding pulley, and the transverse sliding structure includes a transverse sliding groove provided on the pulley and a transverse sliding rail provided on the one-way bearing; the limiting member 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. An annular disconnection groove and a power transmission groove are provided on the inner surface of the inner ring of the one-way bearing, and multiple annular disconnection grooves are provided and arranged evenly along the axis direction; the power transmission groove penetrates through the inner surface of the inner ring of the one-way bearing, and the extending direction of the power transmission groove is parallel to the axis of the one-way bearing; multiple power transmission bosses are provided on the wire winding rotating shaft and arranged evenly 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] The present invention has the following beneficial effects compared with the prior art:

[0056] 1. Based on the theory of traditional Chinese medicine acupoints, the present invention determines whether there is test anxiety and the state of test anxiety by real-time detecting the change of electrical signals of acupoints, ensuring a large parameter correlation, reducing the influence of subjective factors, improving the system reliability. During detection, just align with the acupoints and select the corresponding parameters to start detection, which is convenient for the subjects to use in self-detection, and is more scientific, accurate and efficient.

[0057] 2. By using the bioelectrical signals on the acupoints and based on the weight ratio factors of different acupoints, the present invention conducts comprehensive analysis and judgment of multiple acupoints to improve the accuracy of test anxiety detection, continuously collects the bioelectrical signals of acupoints, and real-time detects the test anxiety of the human body, with higher real-time performance.

[0058] 3. According to the severity of the test anxiety state, the device can provide different levels of reminder signals, including sound, light and vibration, to ensure that users or caregivers can timely notice the abnormal state and relieve the anxiety of people in the severe test anxiety state.

[0059] 4. It solves the problems existing in the existing mainstream detection technologies, such as high detection technical difficulty, complex equipment, difficult operation, and the subjects are prone to have a resistant psychology. 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 will be further described below in conjunction with embodiments and drawings. However, the implementation manners of the present invention are not limited thereto.

[0069] Refer to Figure 1 , the examination anxiety detection method based on acupoint bioelectric signals in this embodiment includes the following steps:

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

[0071] (2) Collect the bio-simulation signals of multiple acupoints of the user through the acupoint signal acquisition end, and process multiple bio-digital signals according to the multiple bio-simulation signals; the multiple bio-digital signals correspond to the multiple acupoints one by one.

[0072] The acupoint examination anxiety database is pre-stored in the data storage module of the intelligent processing terminal, or alternatively, the acupoint examination anxiety data to be set can be typed and stored in the memory through the touch input signal in the display of the intelligent processing terminal before or during the detection; or, the acupoint examination anxiety data to be set can also be typed and stored in the data storage module of the intelligent processing terminal through the button input before or during the detection, so as to form an acupoint examination anxiety database in the intelligent processing terminal.

[0073] (3) Call the pre-stored acupoint examination anxiety database, and obtain the weight ratio factors corresponding to each acupoint from the preset acupoint examination anxiety database; wherein, the calculation method of the weight ratio factors of each acupoint is:

[0074] Use the system state electronic measuring instrument to act on the twelve yuan-acupoints on the left and right sides and the eight confluence points of the eight extra meridians on the body surface of the students with examination anxiety, measure the bioelectric signal values of their acupoints, perform statistical analysis with SPSS26.0 software, and use the Spearman correlation analysis formula to conduct a correlation study to obtain the acupoints related to examination anxiety and their correlation coefficients:

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

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

[0077] sum of left Shenmen + r of right Chongyang and right Shenmai;

[0078] n is the acupoint;

[0079]

[0080] (4) Combine multiple biological digital signals and process them with the weight ratio factors of each acupoint to obtain the test anxiety state value.

[0081] (5) Obtain the test anxiety threshold from the acupoint test anxiety database, compare the size of the test anxiety state value and the test anxiety threshold, and obtain and output the 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, output a detection result indicating that the current state is normal, and continue to detect the test anxiety state; if the test anxiety state value is greater than or equal to the mild test anxiety threshold, output a detection result indicating that the current state is test anxiety and send a reminder signal.

[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 beneficial to ensure the continuous monitoring and evaluation of the test anxiety state of the subject; by outputting an audio signal with a fast rhythm and strong stimulation when the test anxiety state value is greater than or equal to the mild test anxiety threshold and less than the moderate test anxiety threshold, the degree of anxiety arousal is increased; by outputting an audio signal with a slow rhythm, weak stimulation, and relatively soothing when the test anxiety state value is greater than or equal to the severe test anxiety threshold, the test anxiety emotion is relieved, while warning the subject or others in the same environment as the subject, reducing the impact on the student's mentality caused by excessive anxiety, and at the same time providing a risk warning for the severity of psychosomatic problems caused by excessive anxiety, 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 and less than the moderate test anxiety threshold, the detection result of mild test anxiety is output and displayed, and the buzzer or beeper or the client device is controlled by the warning module to emit a reminder sound at the 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 and less than the severe test anxiety threshold, the detection result of moderate test anxiety is output and displayed, and the buzzer or beeper or the client device is controlled by the warning module to emit a reminder sound at the second decibel value; otherwise, while outputting and displaying the detection result of severe test anxiety, the buzzer or beeper or the client device is controlled by the warning module to emit a reminder sound at the third decibel value, and the vibrator or the client device is controlled to enter the 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 classifying the test anxiety state value levels for reminders, different signal reminders are realized at different levels of test anxiety, improving the rationality of the layout, and being able to better warn the test taker and their caregivers, and better avoid accidents.

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

[0089] Regarding the setting of the sound type: Although there is a significant negative correlation between the worry component of test anxiety and learning performance, there is a significant positive correlation between the tension component in test anxiety and learning performance. Moderate levels of anxiety arousal can better activate cognitive function and learning performance, and moderate physiological arousal can promote test performance, that is, the more tense emotions an individual experiences, the better the test scores, and test anxiety individuals only show a promoting effect on learning performance when they show physical tension. Therefore, an audio signal with a fast rhythm and strong stimulation is output during mild test anxiety to increase the arousal level; an audio signal with a slow rhythm and weak stimulation is output during severe test anxiety to relieve test anxiety emotions, such as the sound of ocean waves, rain, birdsong, etc., providing a feeling of calm and relaxation.

[0090] Regarding the setting of the sound volume: The first decibel audio (mild test anxiety): Set at 80 - 85 decibels, this decibel sound is loud, enhancing the arousal level 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, relieving the test taker's test anxiety emotions while reminding their caregivers to take immediate action.

[0091] In addition, according to the IEC60601-1-8 standard, the audio frequency is set between 150 Hz and 1000 Hz, and it is one of the fourth harmonics with the maximum sound level. There are four frequency peaks, and the sound level difference between the maximum four frequency peaks is within 15 dB; the rise time (tr) and fall time (tf) of the high priority are 20 ms, and those of the medium and low priorities are 40 ms. They are all intermittent sounds. The pulse interval (ts) of the high priority is 100 ms, and the actual interval time is ts - 45 ms, that is, 55 ms; the pulse interval (ts) of the medium priority is 200 ms, and the actual interval time = ts - 90 ms, that is, 110 ms; the pulse interval (ts) of the low priority is 500 ms, and only one signal is set without setting the actual interval time.

[0092] See Figures 2-3 , the test anxiety detection device based on acupoint bioelectric signals in this embodiment includes a plurality of acupoint signal acquisition terminals 1 and an intelligent processing terminal. The acupoint signal acquisition terminals 1 are electrically connected to the intelligent processing terminal (in this embodiment, three acupoint signal acquisition terminals 1 are provided, and of course, there can 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. The controller 3 is electrically connected to the display 4 and the power supply 5 respectively. Specifically, the acupoint 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 paste double-sided tape and is adhered to the skin through the double-sided tape, or other structures that can fix the acupoint signal acquisition terminal 1 on the corresponding acupoints can be adopted. The acquisition method of the acupoint signal acquisition terminal 1 can adopt existing technologies, such as other related technologies like CN108158572A.

[0093] The working principle of the test anxiety detection device based on acupoint bioelectric signals in this embodiment:

[0094] First, attach multiple acupoint signal acquisition terminals to the corresponding acupoints of the subject. Among them, the selection of acupoints can be obtained through experiments. By selecting fifteen acupoints highly related to test anxiety among the twelve yuan-acupoints and eight confluence points of the eight extra meridians in the human body: the left Shenmen acupoint, the right Chongyang acupoint, the left Jinggu acupoint, the right Jinggu acupoint, the left Linqi acupoint, the left Taibai acupoint, the left Qiuxu acupoint, the right Gongsun acupoint, the left Taixi acupoint, the left Lieque acupoint, the left Neiguan acupoint, the left Zhaohai acupoint, the right Yangchi acupoint, the left Shenmai acupoint, and the right Shenmai acupoint (the number of acupoints can be selected according to actual needs, which can be 3 - 15). Then, turn on the working power supply, and each acupoint signal acquisition terminal will detect the optimal bio-mimicking signal of the corresponding acupoint and input the optimal bio-mimicking signal into the data acquisition module. The data acquisition module amplifies and filters the bio-mimicking signal in sequence to obtain an analog signal that can be input into the intelligent processing terminal. The intelligent processing terminal performs analog-to-digital conversion processing on the analog signals continuously input by the data acquisition module to obtain bio-digital signals corresponding to the analog signals of each acupoint, and the state of test anxiety is reflected to a certain extent by the magnitude of the bio-digital signals.

[0095] See Figures 4-6 , the acupoint signal acquisition terminal 1 is connected to the controller of the intelligent processing terminal through a wire 6. A storage groove 2 - 1 for storing the acupoint signal acquisition terminal 1 is provided on the side wall of the housing 2, and a plurality of function buttons are provided on the housing 2, and all operations of the detection can be controlled through the plurality of function buttons.

[0096] See Figures 4-6 , an automatic wire winding mechanism for automatically winding the wire 6 is provided in the housing 2. The automatic wire winding mechanism includes a wire winding wheel 7 and a wire winding driving mechanism. The wire winding wheel 7 is rotationally connected to the mounting seat 9 through a wire winding 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 winding wheel 7, and the other end of the wire 6 is fixedly connected to the acupoint signal acquisition terminal 1; the wire winding driving mechanism includes a wire winding driving motor 10 and a wire winding transmission component. The wire winding driving motor 10 is fixedly arranged in the housing 2. The wire winding transmission component includes a synchronous belt 11 and a belt pulley 12, and the synchronous belt 11 and the belt pulley 12 are connected between the wire winding driving motor 10 and the wire winding rotating shaft 8 to achieve power transmission. Through the above structure, driven by the wire winding driving motor 10, the wire winding wheel 7 can rotate in the corresponding direction, so as to wind the wire 6 on the wire winding wheel 7 to achieve automatic wire winding.

[0097] Specifically, the length of the wire 6 in this embodiment can be adaptively set according to actual needs to meet the needs of most people, and the purpose is to be able to reach each main acupoint of the human body; of course, 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] SeeFigures 4-6 The wire take-up drive assembly further includes a drive shaft 13, which is connected to the wire take-up drive motor 10 through a coupling; a plurality of sets of synchronous belts 11 and belt pulleys 12 are provided. Each set of belt pulleys 12 has two belt pulleys 12. One of the belt pulleys 12 in the same set is coaxially arranged on the drive shaft 13, and the other belt pulley 12 in the same set is arranged on the wire take-up rotating shaft 8 through a one-way bearing 14. The belt 11 is connected to the two belt pulleys 12 in the corresponding set; in the wire take-up state, the one-way bearing 14 transmits the power on the corresponding belt pulley 12 to the wire take-up rotating shaft 8. In the wire pay-out state, the one-way bearing 14 disconnects the power connection between the corresponding belt pulley 12 and the wire take-up rotating shaft 8.

[0099] With the above structure, a single motor can be shared to complete multiple sets of wire take-up operations, which is beneficial to simplifying the structure and reducing costs. Further, by providing the one-way bearing 14, during wire take-up, the one-way bearing 14 is locked, so that the power on the corresponding belt pulley 12 is transmitted to the wire take-up rotating shaft 8 to complete the wire take-up work; during wire pay-out, 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 belt pulley 12 and the wire take-up rotating shaft 8 to perform independent wire pay-out work without affecting other wire take-up wheels 7, which is very ingenious.

[0100] See Figures 7-11 The automatic wire take-up mechanism further includes a position-in-place disconnection structure, which includes a mounting shaft 15, a guide wheel set, a disconnection fork 16, a return spring 17 and a limiting member 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 take-up rotating shaft 8; the guide wheel set includes two semi-guide wheels 19 formed by dividing a V-shaped guide wheel from the central plane perpendicular to the axis. The two semi-guide wheels 19 are rotatably connected to the mounting shaft 15, and a wire groove with a variable width and a V-shaped cross-section is formed between the two semi-guide wheels 19; a disconnection driving section 20 is provided on the wire 6, and the size of the disconnection driving section 20 is larger than the size of the wire 6; a limiting ring 21 for limiting one of the semi-guide wheels 19 is fixedly provided on the mounting shaft 15; the disconnection fork 16 includes a fork body and a fork portion 16-1. The fork body is slidably sleeved on the mounting shaft 15, and two fork portions 16-1 are provided and both extend towards the direction of the one-way bearing 14. The two fork portions 16-1 are respectively located on both sides of the one-way bearing 14; the return spring 17 is slidably sleeved on the mounting shaft 15, and both ends of the return spring 17 are respectively abutted against the disconnection fork 16 and the mounting seat 9; the end of the disconnection fork 16 away from the return spring 17 abuts against the other semi-guide wheel 19.

[0101] A lateral sliding structure is provided between the one-way bearing 14 and the corresponding pulley 12. The lateral sliding structure includes a lateral sliding groove 12-1 provided on the pulley 12 and a lateral sliding rail 14-1 provided on the one-way bearing 14. The limiting member 18 is used to limit the lateral 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. An annular disconnection groove 14-2 and a power transmission groove 14-3 are provided on the inner surface of the inner ring of the one-way bearing 14. A plurality of the annular disconnection grooves 14-2 are provided and arranged uniformly along the axial direction. The power transmission groove 14-3 penetrates the inner surface of the inner ring of the one-way bearing 14, and the extending direction of the power transmission groove 14-3 is parallel to the axis of the one-way bearing 14. A plurality of power transmission bosses 8-1 arranged uniformly along the axial direction are provided on the wire winding rotating shaft 8.

[0102] In the power transmission state, the power transmission boss 8-1 is located in the power transmission groove 14-3, and the wire 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 driving section 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 end 1 is located in the corresponding storage groove 2-1.

[0103] See Figures 7-11 , the working principle of the above-mentioned in-place disconnection structure is as follows:

[0104] After the detection work is completed, it is necessary to retract the acupoint signal acquisition end 1 and the wire 6. At this time, it is in the power transmission state. The power transmission boss 8-1 of the wire winding rotating shaft 8 is located in the power transmission groove 14-3 of the one-way bearing 14. Under the drive provided by the wire winding drive motor 10, the power is transmitted to the one-way bearing 14 by the wire winding transmission assembly, and then the power transmission boss 8-1 on the wire winding rotating shaft 8 drives the wire winding rotating shaft 8 to rotate, so as to drive the wire winding wheel to wind the wire 6, and the wire 6 is guided by the two semi-guide wheels 19. At this time, the width of the V-shaped wire groove is the smallest, 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. Figure 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 current state of the test taker is test anxiety, the controller will control the warning module to sound and / or light up for reminder; while when the test anxiety detection result shows that the current state of the test taker is normal, that is, in a non-test anxiety state, the controller will not control the warning module to sound or light up for reminder, that is, the warning module is in a standby state 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 achieve signal connection through a Bluetooth connection method. When the vibrator achieves signal connection with the controller through a Bluetooth connection method, the vibrator and the controller can be separately set and worn or carried on the test taker and / or the person related to the test taker, so as to strengthen the reminder effect and have a better reminder effect.

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

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