具体实施方式Detailed ways
以下结合附图描述本实用新型的具体实现过程，不视为对本实用新型的限制。The specific implementation process of the utility model is described below in conjunction with the accompanying drawings, which is not considered as a limitation of the utility model.

现代科学证实，人在说谎时生理上会发生变化。有一些肉眼可以观察到，如抓耳挠腮、腿脚抖动等一系列不自然的人体动作。还有一些生理变化不易察觉，如：呼吸速率和血容量异常；脉搏加快，血压升高，血输出量增加及成分变化；皮下汗腺分泌增加；眼睛瞳孔放大；胃收缩，消化液分泌异常；肌肉紧张、颤抖。这些生理参量由于受植物神经系统支配，所以一般不受人的意识控制，而是自主的运动，在外界刺激下会出现一系列条件反射现象。Modern science has confirmed that when people lie, physiological changes will occur. There are some unnatural human body movements that can be observed with the naked eye, such as scratching ears and cheeks, shaking legs and feet, and so on. There are also some physiological changes that are not easy to detect, such as: abnormal breathing rate and blood volume; rapid pulse, elevated blood pressure, increased blood output and changes in composition; increased secretion of subcutaneous sweat glands; dilated pupils of the eyes; gastric contraction, abnormal secretion of digestive juices; Nervous, trembling. Because these physiological parameters are dominated by the autonomic nervous system, they are generally not controlled by human consciousness, but autonomous movements.

在具体的测谎过程中，需分阶段进行数据的采集和计算。In the specific polygraph process, data collection and calculation need to be carried out in stages.
在第一测试时段T1中，向被试者提出不涉及测谎内容的常识性问题，以捕捉被试者在正常生理状态下的生理指标。在T1中，脉搏传感器11、呼吸传感器12和皮肤电阻传感器14同时开始周期性的采集数据，并将所采集的数据实时传送至单片机15。该单片机15计算T1中收到的所有数字脉搏信号的平均值作为脉搏参考值。该单片机15计算T1中收到的所有呼吸信号的平均值作为呼吸参考值。具体的，由于呼吸信号包括呼吸频率以及呼吸幅度，故而单片机15可分别对呼吸频率以及呼吸幅度进行计算，以得到呼吸频率参考值以及呼吸幅度参考值。该单片机15计算T1中收到的所有皮肤电阻信号的平均值作为皮肤电阻参考值。In the first test period T1, common-sense questions that do not involve lie detection content are asked to the subject, so as to capture the physiological indicators of the subject in a normal physiological state. In T1 , the pulse sensor 11 , respiration sensor 12 and skin resistance sensor 14 start collecting data periodically at the same time, and transmit the collected data to the single chip microcomputer 15 in real time. The single-chip microcomputer 15 calculates the average value of all digital pulse signals received in T1 as the pulse reference value. The single-chip microcomputer 15 calculates the average value of all respiration signals received in T1 as a respiration reference value. Specifically, since the respiration signal includes respiration frequency and respiration amplitude, the single-chip microcomputer 15 can calculate the respiration frequency and respiration amplitude respectively to obtain a reference value of respiration frequency and a reference value of respiration amplitude. The single-chip microcomputer 15 calculates the average value of all skin resistance signals received in T1 as the skin resistance reference value.
在第二测试时段T2中，正式进入测谎时段，向被试者提出涉及测谎内容的问题，以捕捉被试者的生理指标。在T2中，脉搏传感器11、呼吸传感器12和皮肤电阻传感器14周期性的采集数据，并将所采集的数据实时传送至单片机15。该单片机15计算T2中收到的所有数字脉搏信号的平均值作为脉搏测谎值。该单片机15计算T2中收到的所有呼吸脉搏信号的平均值作为呼吸测谎值，具体可包括呼吸频率测谎值以及呼吸幅度测谎值。该单片机15计算T2中收到的所有皮肤电阻信号的平均值作为皮肤电阻测谎值。In the second test period T2, the polygraph period is formally entered, and the subjects are asked questions related to the content of the polygraph to capture the physiological indicators of the subjects. In T2, the pulse sensor 11, the respiration sensor 12 and the skin resistance sensor 14 collect data periodically, and transmit the collected data to the single-chip microcomputer 15 in real time. The single-chip microcomputer 15 calculates the average value of all digital pulse signals received in T2 as the pulse lie detection value. The single-chip microcomputer 15 calculates the average value of all the respiratory pulse signals received in T2 as the respiratory polygraph value, which may specifically include the respiratory frequency polygraph value and the respiratory amplitude polygraph value. The single-chip microcomputer 15 calculates the average value of all skin resistance signals received in T2 as the skin resistance polygraph value.
T1、T2的具体时长可根据需求预先设定。The specific duration of T1 and T2 can be preset according to requirements.
该单片机15根据脉搏参考值与脉搏测谎值，可计算得到一脉搏变化率fp，例如：The single-chip microcomputer 15 can calculate a pulse rate of change fp according to the pulse reference value and the pulse lie detection value, for example:
脉搏变化率fp＝(脉搏测谎值-脉搏参考值)/脉搏参考值。Pulse rate of change f p = (pulse polygraph value-pulse reference value)/pulse reference value.
不以此为限，其他可以表现脉搏参考值与脉搏测谎值之间的变化程度的计算公式均可包含于本实用新型的范围内。Not limited thereto, other calculation formulas that can represent the degree of change between the pulse reference value and the pulse polygraph value can be included in the scope of the present invention.
同理，根据呼吸频率参考值与呼吸频率测谎值，可计算得到一呼吸频率变化率fb。根据呼吸幅度参考值与呼吸幅度测谎值，可计算得到一呼吸幅度变化率Ab。根据皮肤电阻参考值与皮肤电阻测谎值，可计算得到一皮肤电阻变化率Rs。Similarly, according to the respiratory frequency reference value and the respiratory frequency polygraph value, a respiratory rate change rate f b can be calculated. According to the breath amplitude reference value and the breath amplitude polygraph value, a breath amplitude change rate A b can be calculated. According to the skin resistance reference value and the skin resistance polygraph value, a skin resistance change rate R s can be calculated.
该单片机15中预先存储有各种变化率所对应的权重值，脉搏权重值a1、呼吸频率权重值a2、呼吸幅度权重值a3、皮肤电阻权重值a4，并根据以下公式(1)，进行测谎计算。The single-chip microcomputer 15 pre-stores weight values corresponding to various rates of change, pulse weight a 1 , respiratory frequency weight a 2 , respiration amplitude weight a 3 , skin resistance weight a 4 , and according to the following formula (1 ) for polygraph calculations.
K＝a1*fp+a2*fb+a3*Ab+a4*Rs (1)K＝a 1 *f p +a 2 *f b +a 3 *A b +a 4 *R s (1)
单片机15对K进行判断，如果K大于一临界值μ，视为被试者的各项生理指标超过阈值，则判定被试者在说谎。如果K小于等于临界值μ，视为被试者的各项生理指标未超过阈值，则判定被试者未说谎。The single-chip microcomputer 15 judges K, if K is greater than a critical value μ, it is considered that each physiological index of the subject exceeds the threshold, and then it is determined that the subject is lying. If K is less than or equal to the critical value μ, it is considered that each physiological index of the subject does not exceed the threshold, and it is determined that the subject has not lied.
单片机15还可与蜂鸣器16和/或显示器17连接。如果单片机15判定被试者说谎，蜂鸣器16可发出警报。或者，由显示器17进行警报的输出显示。进一步的，蜂鸣器16可预先设置有两种不同的鸣响，以分别对应说谎与未说谎的情况，发出不同的提示。显示器17也可对说谎与未说谎这两种情况，分别进行警报的输出显示。在另一实施例中，单片机15可不进行即时警报，而仅进行数据的收集，或者通过连接线传输至其他数据分析处理平台。Single-chip microcomputer 15 can also be connected with buzzer 16 and/or display 17. If the single-chip microcomputer 15 determines that the subject is lying, the buzzer 16 can send an alarm. Alternatively, the output display of the alarm is performed on the display 17 . Further, the buzzer 16 can be preset with two different beeps, so as to give different prompts respectively corresponding to the situation of lying and not lying. Display 17 also can carry out the output display of warning respectively to these two kinds of situations of lying and not lying. In another embodiment, the single-chip microcomputer 15 may not perform an instant alarm, but only collect data, or transmit it to other data analysis and processing platforms through a connection line.
单片机15还可通过用于测谎的其他现有技术中的计算公式进行测谎计算，均在本实用新型的公开范围内。例如，单片机15可计算各个参数的参考值与对应的测谎值之间的比值，当各个参数的比值均处于预先设定的标准值范围时，单片机15将其视为未说谎，当各个参数的比值超出预先设定的标准值范围时，单片机15将其视为说谎。The single-chip microcomputer 15 can also perform lie detection calculations through calculation formulas used in other prior art for lie detection, all within the disclosure scope of the present utility model. For example, the single-chip microcomputer 15 can calculate the ratio between the reference value of each parameter and the corresponding polygraph value. When the ratio of each parameter is in the preset standard value range, the single-chip microcomputer 15 regards it as not lying. When the ratio of exceeds the preset standard value range, the single-chip microcomputer 15 regards it as lying.
在操作方面，仅需将脉搏传感器11、呼吸传感器12、皮肤电阻传感器14的采集端设置在被试者身上，启动测试仪，则测试仪将自动发出测谎的结果，无需操作者进行额外的维护。In terms of operation, it is only necessary to set the collection terminals of the pulse sensor 11, respiration sensor 12, and skin resistance sensor 14 on the subject, start the tester, and the tester will automatically send out the result of the lie detection, without the need for the operator to perform additional operations. maintain.
