Sleep is the rest stage for energy recovery and storage after daily activities The sleep quality in this stage is closely related to health Temperature, humidity, oxygen content, noise, illumination, anion, etc of the sleeping environment are connected with the sleep quality tightly In order to gain better sleep effect, it is necessary to provide sleeping environment which can be automatically adjusted according to physiological parameters This paper designs the blood oxygen saturation and heart rate signal collector using MSP430F2274 and CC2500 as core module based on the development tool eZ430-RF2500 from Texas Instruments, achieves to collect process and wirelessly transmit pulse signals, and provides measurement methods of physiological parameters for the sleeping environment regulating system%睡眠是人在一天活动后进行精力恢复和能量贮存的休复阶段.该阶段的睡眠质量好坏与身体健康密切相关,而睡眠环境的温度、湿度、氧含量、噪音、光照、负离子等与睡眠质量有着紧密的联系.为了让人可以获得最佳睡眠效果,有必要提供可根据人体生理参数进行自动调节的睡眠环境.基于TI公司的eZ430-RF2500开发工具,设计开发了以MSP430F2274芯片和CC2500芯片为核心模块的血氧与心率信号检测环节,实现对脉搏波信号的采集、处理与无线发送,为睡眠环境调节系统提供前级人体生理参数的测量手段.
