4. Heart rate and blood oxygen detection principle
Oximeter principle is based on reducing hemoglobin (R Hb), oxyhemoglobin (O2 Hb) absorption spectrum
characteristic in the red and near red light area as a basis, used Lambert Beer's law establishing empirical data
processing. The instrument works by using optical detection technology combined with volume pulse oximetry
tracings technology, using two beams of different wavelengths of light (660nm red and 940nm near infrared light)
from the perspective clamp finger-type sensor by irradiating human nail tip then photosensitive element acquires the
measurement signal, after information is processed by the electronic circuitry and microprocessor, the measured
results will be displayed.
5. Remote video monitoring principle
The entire system is Internet-based and run by a local resettlement surveillance cameras, through video server
compression uploading to the Internet, and then transmitted to the video monitoring server monitoring center
through the network, and then use the mobile Internet, landing to video surveillance server, then you can get
monitoring resources. The front surveillance camera is connected wirelessly to the Internet; also you can check
video in your mobile phone using the wireless Internet, which bring users new experience.
6. Detection principle of fetal heart monitoring
Fetal heart monitoring is using ultrasonic detection technology to complete the fetal heart rate detection. Its role
is by monitoring fetal movement and fetal heart rate to reflect the status of the fetus in the mother's body
condition, fetal heart too fast or too slow is problematic performance, you can roughly judge the health of the
baby according to the data of the display.
7. Interactive Voice principle
(1) The voice recognition: use a microphone to record sound, and then send it to an online server, compare it with
database to get the content of dialogue.
(2) A smart answer: use dialogue to search online matching answer, then feedback the answer to the terminal, and
finally read out by the software.
