Research on the meter´s pulse signal processing based on sleep-monitoring alarm system

It is essential to study pulse signal processing while researching the embedded sleep-monitoring alarm system. Through the improvement of thin-film pulse sensor, the sensor location-related issues are solved. At the same time, low frequency filtering, second-level enlargement, and multiple analysis by using an embedded microprocessor are involved. Comparing the pulse parameters during human sleep under normal circumstances and the actual measurement of the pulse parameters can determine whether the sleep condition is normal. Under the condition of not influencing the users´ sleep, the stimulator disturbs their insomnia mechanism and then improves the sleep quality. Signs of sudden cardiovascular and cerebrovascular diseases are notified by the alarm signal that is sent out immediately under unusual circumstances.
