Sleep and fatigue monitoring class wrist-watch device
Technical field:
The utility model relates to the device of sleep and fatigue monitoring.
Background technology:
Along with the development of society and the progress of science and technology, urban life rhythm is accelerated working 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.The monitoring of sleep quality and fatigue state has more and more been caused the concern of modern medicine.For the staff in some special posies, such as pilot and driver etc., their drowsiness is with fatigue even can lead to major accident, damages 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, working load 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, and the reasons such as line complexity are only suitable for using at hospital bed, and the place to use environment is limited, and comfort level is not good enough, can't be used 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, the measured only need couch and get final product at mattress in the use procedure, need not to paste electrode, the comfort level that this has improved sleep monitor has greatly reduced the complexity that operates.At present this kind method is exclusively used in Sleeping Center and laboratory, serves the special personnel such as pilot, driver, sportsman, 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, eyeshade, noopsyche test questionnaire or software, human action video 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 can't under people work living condition, realize portable long-time round-the-clock measurement, can't satisfy the requirement of daily monitoring and health care.
The utility model content:
The utility model purpose: for the human body portable sleep and fatigue detecting equipment that a cover has 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, sportsman monitored in time feedback and prompting, safeguard work safety, protection individual and other people security of the lives and property with fatigue state.
In order to reach as above purpose, the utility model is taked following technical scheme: comprise skin resistance sensor, temperature sensor, atmosphere pressure sensor, acceleration transducer; All link to each other with core processor with upper sensor, also comprise the pin-saving chip that links to each other with core processor.
The further technical scheme of the utility model is: described skin resistance sensor is on device and the human body one side of joining two metal electrodes to be arranged, and its effect is the measurement Skin Resistance.
The further technical scheme of the utility model is: it is inner good with electrode contact that described temperature sensor is installed in device, can be with 0.1 ℃ precision measure skin human body skin temperature.
The further technical scheme of the utility model is: also comprise calendar chip, it links to each other with core processor, can provide pin-saving chip for core processor.
The further technical scheme of the utility model is: also comprise the usb data transmission interface that LCDs and data derive.
The further technical scheme of the utility model is: also comprise geomagnetic sensor, its effect is: changing subsidiary human motion and attitude by measuring the orientation, magnetic field, is the important evidence of judging fatigue level of human body.
The further technical scheme of the utility model is:: also comprise three-axis gyroscope, its effect is: measure the human motion situation, for judging that fatigue level of human body provides foundation.
The monitoring method of sleep and fatigue monitoring normalization dingus is characterized in that: comprise following steps:
Uninterruptedly store by dingus monitoring skin next to the skin resistance, Pi Wen, acceleration, atmospheric pressure and to raw data;
The survey data are carried out following calculating: calculate respectively the geometric mean of three-dimensional acceleration on each time point, three-dimensional magnetic field, three dimensional angular speed, formula is as follows
XYZ 3-axis acceleration geometric mean:
XYZ three-axle magnetic field geometric mean:
XYZ three axis angular rate geometric means:
Then top three indexs are superposeed according to separately weight coefficient and obtain the weighted geometric mean;
Y=k
1Y
1+ k
2Y
2+ k
3Y
3K1, k2, k3 are the norm weighting coefficient;
Result of calculation is made the following judgment: at first judge body temperature and skin resistance data whether in range of normal value, thereby judge whether fatigue detection device is worn correctly; Then the weighted geometric mean Y in the unit interval is carried out integration, obtain becoming positively related judge index with activity in the unit interval, skin impedance variation trend is judged human-body fatigue jointly in this index and corresponding time period, if Y value and Skin Resistance variable quantity have all surpassed threshold value, then can obtain according to the size of correlation values the degree of fatigue classification;
Output fatigue results and index.
The further technical scheme of the utility model is: described degree of fatigue is described as Pyatyi, and is 1. not tired, and 2. slight tired, 3. moderate is tired, and 4. severe is tired, and is 5. extremely tired.
Adopt as above the utility model of technical scheme, has following beneficial effect: under the condition that does not affect the routine work life, long-time continuous human body fatigue and sleep state, conveniently self-condition is in time monitored effective Feedback, improve health conditions and quality of life, ensure the personal security of the lives and property.
