Description

The monitoring method of sleep and fatigue monitoring class wrist-watch device and normalization dingus

Technical field:

The present invention relates to the method and apparatus of sleep and fatigue monitoring.

Background technology:

Along with social development and scientific and technological progress, urban life rhythm is accelerated operating pressure and is increased, and there are sleeping problems in various degree in many people, usually feels tired and tired, if can not get for a long time paying attention to damaging possibly health.Monitoring to sleep quality and fatigue state has more and more caused the concern of modern medicine.For the staff in some special posies, such as pilot and driver etc., their drowsiness and fatigue even can lead to major accident, damage other people safety and health, therefore must pay much attention to people's fatigue state and sleep state.

In addition, people's sleep state and fatigue state can constantly change along with the conditions such as environment, time, workload and factor, just want to understand and grasp more accurately and must long-time continuous monitor, just need a kind of Low Power Consumption Portable equipment that can carry, long-time all weather operations when not affecting people's normal operation and life.

Lead the sleep detection instrument is present the most frequently used sleep detection means more, is internationally recognized goldstandard, is widely used in each large medical institutes.But, because volume is larger, human body sensor connects more, the reasons such as line complexity are only suitable for using on hospital bed, and the place to use environment is limited, and comfort level is not good enough, can't be for daily sleep and fatigue monitoring.

For solve lead more sleep detection instrument cost high, consume the problems such as large, complicated operation, comfort level be poor, people have developed the noiseless sleep detection analyser of mattress formula.Instrument system is comprised of list/a plurality of mattresses and the other device of bed, transmission line, central control box and main frame, in use procedure, the measured only need couch and get final product on mattress, without pasting electrode, the comfort level that this has improved sleep monitor greatly, reduced the complexity operated.At present this kind of method is exclusively used in Sleeping Center and laboratory, serves the special personnel such as pilot, driver, athlete, also exist the instrument volume greatly, not portable, the problem such as environment for use is limited.

The fatigue detecting aspect, common method has eeg measurement, flicker fusion frequency, noopsyche test, action measure of the change at present.These methods need special instrument and equipment to realize, such as electroencephalograph, electrode, and flashing rate instrument, eyeshield, noopsyche test questionnaire or software, human action camera, sign shiner.

The problems such as existing fatigue and sleep monitor instrument and method ubiquity volume equipment are large, the environment for use condition is limited, all portable long-time round-the-clock measurement can't be under people work the living condition, realized, the requirement of daily monitoring and health care can't be met.

Summary of the invention:

Goal of the invention: for a set of human body portable sleep and fatigue detecting equipment with independent intellectual property right is provided, can long-time round-the-clock human body sleep state and fatigue state, safeguard health, improve the quality of living.Self sleeping of the crowds such as pilot, driver, athlete monitored to feedback and prompting in time, safeguard work safety, protection individual and other people security of the lives and property with fatigue state.
