Embodiment Construction

[0079] Such as Figure 1 ~ Figure 2 Shown is an intelligent human body pH meter and a method for non-invasively detecting human physical and mental health state parameters. The detector includes a PH sensor, a high-impedance amplifier containing CA3140 and an adder containing R3~R7, R11~R12 and LM358 operational amplifiers, and is characterized in that it also includes a MSP430F149 single-chip microcomputer, in which the basic detection program and special-purpose Detection program, the single-chip microcomputer comes with a 12-bit A / D converter, which can convert the 0-2500mv analog signal of sialic acid-base state collected by the pH sensor and processed by the high-impedance operational amplifier and adder into a digital signal, and the single-chip microcomputer Complete the mv-A / D-PH conversion process, and then complete the corresponding technical analysis process according to the special detection program, and at the same time issue instructions to the FLASH voice chip a...

Abstract

The invention discloses an intelligent human-body acid-base detector and a method for detecting parameters of physical and psychological health. The detector comprises a pH sensor, a high-impedance amplifier and an adder. The detector is characterized in that the detector also comprises a MSP430F149 single chip microcomputer in which a basic detection program and a special detection program are written; the single chip microcomputer has a 12-bit A / D converter which can convert 0-2,500 mv analog signals about saliva acid-base state, which are acquired by the pH sensor, subjected to high-impedance operational amplification and processed by the adder, into digital signals; mv-A / D-PH conversion is completed by the single chip microcomputer; corresponding technical analysis is completed according to the special detection program; meanwhile, instructions are sent out to a FLASH speech chip and a display driver chip; and detection results are reported in characters and voice through an LCD and a loudspeaker. The invention is used for detecting and judging the pH value of human body fluid and the fatigue states, physical ability reserve and emotional stress of drivers.

Description

technical field [0001] The invention relates to an intelligent human body acid-base meter and a method for indirect detection of multiple human physical and mental health state parameters in a non-invasive way through saliva pH value analysis, quantitative detection and qualitative analysis of its physiological parameters, and corresponding medical and health care expert suggestions. . Background technique [0002] Classical medicine believes that the healthy body fluids of human beings should be between PH7.35-7.45, and this state is called physiological acid-base balance. Only by maintaining the acid-base balance of body fluids can various physiological functions be in the best state. Once it is in an acidic or alkaline state, it will lead to deterioration of health. Slight imbalance will lead to decline in human body function; severe imbalance will lead to various diseases of unknown cause, and it will not be cured for a long time, seriously endangering health, and its ...
