睡眠监测的控制系统

Control system of sleep detection

目的:在不影响被测者睡眠过渡过程的情况下,准确测评睡眠过渡状态,研究入睡的历程、失眠的机制以及解除失眠的有效措施。方法:融合认知科学、生物控制论和信息论,借鉴、利用认知行为学控制失眠的理论、方法,以及现代微电子技术和计算机技术的新成果,根据人类睡眠过渡过程的特征,构造客观、定量、无干扰、不唤醒的更接近人类自然睡眠方式的新研究方法,以ARM微控制器和VxWorks实时操作系统为基础的“微型腕式嵌入式计算机”来中断从清醒到睡着这一过渡过程中的失控思维活动。结果:“腕式嵌入式计算机”的微小结构(包括传感器)以及它与环境的独立,保证了机-脑接口的无干扰性。使用者的反应只需以任意方式的手指微动表达,而传感器检测到的信号的真伪通过实时处理、模式识别便可确认,则保证了机-脑接口的无唤醒性。结论:机-脑接口有利于入睡,对睡眠没有干扰和唤醒。

AIM： In order to monitor and evaluate the sleep, transition state and research on course of sleep, basic mechanisms of insomnia and effective measure to relieve insomnia under the natural sleep. METHODS： The new research method which syncretize cognitive science, biology cybernetics and information theory, utilize the theory and method of insomnia controlling of cognitive ethology as well as the new harvest of modern micro-electronic technique and computer technique were objective and quantificational without interference. This method was more close to the natural sleep mode of human being and it interrupted the actives which lose control of thought with a small wrist-watch Like embedded computer which was based on VxWorks real time operation system and ARM processor. RESULTS： The small size and free connection of wrist-watch like embedded computer ensured that the computer-brain interface had no interference to transition. With the non-restriction and micro-action detection technique based on the embedded computer, the subject＇s reaction was expressed by bending the finger slightly in any direction, and the truths of signals from sensor were determined by real-time processing and pattern recognizing. So the detection technique ensured that computerbrain ,interface did not wake up subject. CONCLUSION： The computer-brain interface can make people fall asleep quickly and do not wake up or interfere with subject.
