Meridian and collateral detector data acquisition system based on signal differential amplification circuit

Abstract

The invention discloses a meridian and collateral detector data acquisition system based on a signal differential amplification circuit. The meridian and collateral detector data acquisition system is mainly composed of a detector data acquisition system and a probe assembly, a grab handle and a main controller which are all connected with the detector data acquisition system. The grab handle is connected with the probe assembly. The detector data acquisition system is composed of a central controller and an LED display, a USB interface, an instrument parameter prestoring module, an A / D conversion module and a power supply which are all connected with the central controller. The meridian and collateral detector data acquisition system is characterized in that a signal regulation filter circuit and the signal differential amplification circuit are sequentially connected between the probe assembly and the A / D conversion module in series, and a voltage stabilization, rectification and filter circuit is connected between the central controller and the power supply in series. By means of the meridian and collateral detector control system, data accuracy of detection and stability of detected data are effectively improved, and data acquisition accuracy of a human body meridian and collateral detector is improved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a data acquisition system of a meridian detector based on a signal differential amplifier circuit. Background technique [0002] Because in life, people often engage in a lot of physical and mental work, so they often feel physically and mentally exhausted. At this time, people will usually obtain their own physical condition through the data collected by the human meridian detector, so that it is convenient to adopt reasonable methods to relieve fatigue. [0003] However, the data acquisition system of the human body meridian detector in the prior art is relatively simple, its stability is poor, and the collected data is inaccurate, which leads to inaccurate results of the human body condition obtained from the detection. Contents of the invention [0004] The purpose of the present invention is to overcome the defects of relatively simple data acquisition system, p...
