Embodiment Construction

[0029] Such as figure 1 As shown, a monitoring device for the computer operator's health includes a micro-power biological radar front-end that radiates a narrow pulse signal non-contact to the computer operator. The echo signal is output to the USB acquisition card through variable delay and related detection. The USB acquisition card digitizes the breathing and heartbeat signals and connects them to the data processing module in the computer for result display and control for subsequent software processing; at the same time, it provides 8 The digital high and low level controls the variable delay line in the front end of the micropower biological radar, realizes the tomographic scanning of the distance, and provides +5V power supply to the entire hardware system.

[0030] The micropower bioradar front-end includes a pulse signal source, a narrow pulse shaping circuit, a variable delay line circuit, a correlation detection circuit, an integrator and a differentiator. The fro...

Abstract

The invention discloses a device and a method for monitoring the health of a computer operator; the device comprises a micro-power bio-radar front end used for radiating a narrow pulse signal to the computer operator in a non-contact way; a breath or heartbeat echo signal which is reflected by the chest wall of the computer operator is output into a universal serial bus (USB) acquisition card by the micro-power bio-radar front end through variable delay and related detection; and output of the USB acquisition card is connected with a data processing module used for result displaying and controlling. The method for monitoring the health of the computer operator can be used for detecting the breath signal and the heartbeat signal of the computer operator in a non-contact way and processing by a variable delay line, adaptive filtering, autocorrelation analysis, power spectrum estimation and the like, thus effectively inhibiting other movement interference of the operator, accurately monitoring the respiratory rate and the heart rate of the computer operator, comparing the respiratory rate and the heart rate with the preset threshold values, and giving out an alarm for prompting or automatically turning off a computer so as to force the computer operator to have a rest.

Description

technical field [0001] The invention relates to a device and method for monitoring human health, in particular to a device and method for monitoring the health of computer operators through non-contact detection of breathing rate or heart rate. Background technique [0002] With the advancement of science and technology, modern office syndrome, especially "high-tech disease" has gradually become a modern occupational disease. The computer can be said to be one of the greatest inventions of this century. With it, the way people work, live and study has undergone epoch-making changes. With the popularization of the Internet and computers, people rely more and more on computers. Many people work at desks in front of computers all day long, addicted to the Internet world of unlimited communication. But when it brings various conveniences to people, it also brings troubles thereupon. People are more or less worried that engaging in computer work for a long time will have many ad...
