Embodiment 1
[0032] Such as figure 1 Shown, a kind of meridian detector, comprises the power supply of power supply and controller connected, also comprises the meridian signal sensor that is used to measure the meridian resistance value and the meridian signal collector that is used to collect the meridian resistance value signal, the meridian signal The signal output end of the sensor is connected with the signal input end of the meridian signal collector, and the signal output end of the meridian signal collector is connected with the controller.
[0033] In the above embodiment, in order to avoid the error generated by the AC signal excitation and conversion measures, the power supply is connected to the meridian signal sensor and the controller respectively, wherein the meridian signal sensor is controlled by the power supply Directly supply power, and at the same time, in order to ensure the normal operation of the controller with the same power supply, the controller is connected wi...
Embodiment 2
[0037] Such as figure 1 As shown, a meridian detector, its basic structure setting and detection method are the same as embodiment 1, specifically, in order to ensure that the measured data does not deviate from the original meridian real state, a meridian signal sampling circuit is also provided, and the meridian signal The sampling circuit is connected in series with the meridian signal sensor and the power supply; when detecting, the meridian signal sampling circuit is connected in series with the meridian signal sensor, the measured meridian and the power supply to form a closed loop.
[0038] In the above embodiment, in order to ensure the accuracy of the measurement and the safety of the human body, the current of the closed loop is preferably 30 μA-100 μA, and the meridian resistance measured by the meridian signal sensor is preferably ≤1050 KΩ.
Embodiment 3
[0040] Such as figure 1 As shown, a meridian detector, its basic structure setting and detection method are the same as embodiment 1 or embodiment 2, specifically, it also includes the following settings: the meridian signal sensor includes a fixed measurement end and a mobile measurement end, wherein the The fixed measurement terminal is connected with the negative terminal of the power supply, and the mobile measurement terminal is connected with the positive terminal of the power supply; the fixed measurement terminal includes a fixed electrode connected to the measurement wire, and the mobile measurement terminal includes a The measuring electrodes to which the measuring leads are connected. When measuring, the meridian signal sensor measures the meridian resistance value of the meridian to be measured through its fixed measuring end and moving measuring end, wherein, when detecting, preferably, the fixed measuring end is always fixedly placed in the general path of human ...
