A novel embedded sleep-monitoring alarm equipment

A novel sleep-monitoring alarm equip-ment based on embedded technology and ARM chips is designed in this paper. The data of sphygmic signal was measured by piezo-film sphygmo-transducers and processed by an embedded microcontroller. The sphygmic data of a person´s sleeping in normal case is compared with those detected by the transducer designed in this paper to judge whether the person´s sleeping condition is normal. The sleeping quality will be improved by using the excitor-device to disturb the insomnia mechanism without affecting the user´s sleeping process. Once any abnormal condition occurs, an alarm signal will send out. The equipment can solve the problem caused by the first-aid of the heart disease and have bright market.
