The detection device 100 includes: a measurement belt 9 , a plurality of measurement nodes 1 attached to the measurement belt 9 and at least one data collection node 2 .
测量带9可以是块状、圆形或其它形状，在优选的实施例中，测量带9应优选为长条带状。在具体实施例中，由于附着在测量带9上的多个测量节点1要与人体皮肤接触，因此，测量带9优选采用弹性材料，可保证多个测量节点1能够很好地与皮肤接触，并且能够控制测量带9对人体皮肤施加的压力。The measuring tape 9 can be block, circular or other shapes, and in a preferred embodiment, the measuring tape 9 should preferably be in the shape of a long strip. In a specific embodiment, since a plurality of measurement nodes 1 attached to the measurement belt 9 will be in contact with human skin, the measurement belt 9 is preferably made of an elastic material, which can ensure that the plurality of measurement nodes 1 can be in good contact with the skin, And it can control the pressure exerted by the measuring belt 9 on the skin of the human body.

Multiple rows of measurement nodes 1 can be arranged on the measurement belt 9 , and in a preferred embodiment, the plurality of measurement nodes 1 are arranged in an array.
数据收集节点2与各个测量节点1信号连接，收集各测量节点1采集的人体体表待测区域的电信号数据。每个测量节点1将其采集的电信号数据只发送给一个数据收集节点2；每个数据收集节点2可收集多个测量节点1采集的电信号数据。在优选的实施例中，由于测量带9为弹性材料，能够伸长或缩短，因此，为了确保测量节点1与数据收集节点2之间的数据线不被损坏，应优选采用可伸缩的导线耦合需要信号连接的测量节点1和数据收集节点2。The data collection node 2 is signal-connected with each measurement node 1, and collects the electrical signal data of the area to be measured on the human body surface collected by each measurement node 1. Each measurement node 1 sends the electrical signal data collected by it to only one data collection node 2; each data collection node 2 can collect electrical signal data collected by multiple measurement nodes 1. In a preferred embodiment, since the measuring band 9 is an elastic material, it can be stretched or shortened.

Measurement node 1 and data collection node 2 that require a signal connection.
在一种具体实施例中，请参考图3，每个测量节点1包括：激励源模块11、测量电极模块12和信号分析模块13。其中，In a specific embodiment, please refer to FIG. 3 , each measurement node 1 includes: an excitation source module 11 , a measurement electrode module 12 and a signal analysis module 13 . in,
激励源模块11用于接触人体体表待测区域，产生激励人体体表待测区域的电信号。在一种具体实施例中，激励源模块2可以采用现有的激励信号方式，例如方波信号、正弦信号等。激励待测区域的电信号优选为电流信号，可以通过一对激励电极(111和112)施加到人体待测皮肤区域，激励电极(111和112)优选采用柔性干电极。一种激励方式为：直接数字频率合成电路(DDS)113按一定模式输出正弦电压信号，而后由压控电流源(VCCS)114输出恒定激励电流，通过激励电极(111和112)加载于人体皮肤上，当然，考虑到直接数字频率合成电路(DDS)113输出的电压信号比较微弱或有噪音，因此，直接数字频率合成电路(DDS)113输出的电压信号在输入压控电流源(VCCS)114之前，还可以经放大滤波电路115进行放大和滤波。The excitation source module 11 is used for contacting the area to be measured on the body surface of the human body to generate electrical signals for exciting the area to be measured on the body surface of the human body. In a specific embodiment, the excitation source module 2 may use an existing excitation signal, such as a square wave signal, a sinusoidal signal, and the like. The electrical signal to excite the area to be measured is preferably a current signal, which can be applied to the skin area of the human body to be tested through a pair of excitation electrodes (111 and 112). The excitation electrodes (111 and 112) are preferably flexible dry electrodes. One excitation method is: the direct digital frequency synthesis circuit (DDS) 113 outputs a sinusoidal voltage signal according to a certain pattern, and then the voltage-controlled current source (VCCS) 114 outputs a constant excitation current, which is loaded on the human skin through the excitation electrodes (111 and 112) Of course, considering that the voltage signal output by the direct digital frequency synthesis circuit (DDS) 113 is relatively weak or noisy, therefore, the voltage signal output by the direct digital frequency synthesis circuit (DDS) 113 is input to the voltage-controlled current source (VCCS) 114 Before, amplification and filtering can also be performed by the amplification and filtering circuit 115 .
测量电极模块12用于接触人体体表待测区域，采集人体体表待测区域的电信号，优选采集电压信号。在一种具体实施例中，测量电极模块12的采样电极(121和122)接触人体待测皮肤区域，采样得到的电压信号，并输出给信号分析模块13，在优选的实施例中，测量电极模块12还可以将采样得到的电压信号经放大消噪后再输出给信号分析模块13。需要说明的是，每对采样电极(121和122)应位于一对激励电极(111和112)之间；采样电极(121和122)也应优选采用柔性干电极。The measuring electrode module 12 is used to contact the area to be measured on the body surface of the human body, and collect electrical signals, preferably voltage signals, of the area to be measured on the body surface of the human body. In a specific embodiment, the sampling electrodes (121 and 122) of the measuring electrode module 12 contact the skin area to be measured of the human body, and the voltage signal obtained by sampling is output to the signal analysis module 13. In a preferred embodiment, the measuring electrodes The module 12 can also output the sampled voltage signal to the signal analysis module 13 after amplifying and eliminating noise. It should be noted that each pair of sampling electrodes (121 and 122) should be located between a pair of excitation electrodes (111 and 112); the sampling electrodes (121 and 122) should preferably also be flexible dry electrodes.
信号分析模块13耦合至测量电极模块12，根据测量电极模块12采集的电信号分析人体体表待测区域的电特性并输出电特性数据。在优选的实施例中，输入信号分析模块13的信号为数字信号，因此，在测量电极模块12和信号分析模块13之间还可以优选耦合模数转换器(图3中ADC2)对测量电极模块12输出的采样信号进行模数转换。电特性可以根据需要进行分析，电特性可以包括幅值、和/或相位。以电特性包括幅值和相位为例进行说明。信号分析模块13包括相角检测单元131和幅值检测单元132，相角检测单元131包括两个信号输入端。测量电极模块12输出的电压信号分成两路，一路耦合至相角检测单元131的一个信号输入端，另一路耦合至幅值检测单元132。其中，幅值检测单元132可以采用现有的电路方案实现，例如得到一路采样信号后，幅值检测单元42通过逐一比较采样值，找出最大采样值，然后对获得的最大采样值除以前置放大的倍数(增益倍数)，即为人体体表待测区域采集到的电压信号的幅值。；相角检测单元131的另一个信号输入端耦合至激励源模块11，具体为直接数字频率合成电路(DDS)113的信号输出端，用于输入直接数字频率合成电路(DDS)113的电压信号。需要说明的是，如果激励源模块11的电压信号经放大滤波电路115进行放大和滤波，则应输入放大和滤波后的电压信号。在优选的实施例中，相角检测单元131采用数字鉴相方式，因此，激励源模块11的电压信号输入相角检测单元131之前还应通过模数转换器(如图3中ADC1)进行模数转换。在一种具体实施例中，相角检测单元131可以通过数字鉴相器基于CORDIC算法(CoordinateRotationDigitalComputer)实现。The signal analysis module 13 is coupled to the measurement electrode module 12, and analyzes the electrical characteristics of the area to be measured on the human body surface according to the electrical signals collected by the measurement electrode module 12 and outputs electrical characteristic data. In a preferred embodiment, the signal of the input signal analysis module 13 is a digital signal, therefore, it is also possible to preferably couple the analog-to-digital converter (ADC2 in Fig. 3) to the measurement electrode module between the measurement electrode module 12 and the signal analysis module 13 12 output sampling signals for analog-to-digital conversion. The electrical characteristics can be analyzed as needed, and the electrical characteristics can include amplitude, and/or phase. Take electrical characteristics including amplitude and phase as an example for illustration. The signal analysis module 13 includes a phase angle detection unit 131 and an amplitude detection unit 132, and the phase angle detection unit 131 includes two signal input terminals. The voltage signal output by the measuring electrode module 12 is divided into two paths, one path is coupled to a signal input terminal of the phase angle detection unit 131 , and the other path is coupled to the amplitude detection unit 132 . Among them, the amplitude detection unit 132 can be implemented by using an existing circuit scheme. For example, after obtaining one channel of sampling signals, the amplitude detection unit 42 finds the maximum sampling value by comparing the sampling values one by one, and then divides the obtained maximum sampling value by the preceding The amplification factor (gain factor) is the amplitude of the voltage signal collected from the area to be measured on the surface of the human body. Another signal input terminal of the phase angle detection unit 131 is coupled to the excitation source module 11, specifically the signal output terminal of the direct digital frequency synthesis circuit (DDS) 113, for inputting the voltage signal of the direct digital frequency synthesis circuit (DDS) 113 . It should be noted that if the voltage signal of the excitation source module 11 is amplified and filtered by the amplification and filtering circuit 115, the amplified and filtered voltage signal should be input. In a preferred embodiment, the phase angle detection unit 131 adopts a digital phase detection method, therefore, the voltage signal of the excitation source module 11 should also be analog-to-digital converter (such as ADC1 in Figure 3) before the input phase angle detection unit 131. number conversion. In a specific embodiment, the phase angle detection unit 131 may be realized by a digital phase detector based on a CORDIC algorithm (CoordinateRotationDigitalComputer).
