Provided is portable sleep monitoring equipment. Hospitals normally adopt polysomnography system to detect patients' electroencephalograms, electro-oculograms, lower jaw electromyograms, oro-nasal airflow, breathing movement, electrocardiograms, blood oxygen, snore, limb movement, positions and other parameters, and then the patients' deep and light sleep cycles and quality are analyzed. The portable sleep monitoring equipment includes a power supply management unit, a communication unit and an acceleration sensor and further includes a physical sign monitoring module; the physical sign moduleis provided with a red light LED, an infrared light LED and a photosensor; a shell of the portable sleep monitoring equipment is made of a light-proof material, and the portions, corresponding to theLEDs and the photosensor, of the shell are made of a light transmittance material. The communication unit includes a wireless communication unit, an information relay unit and a server, wherein the information relay unit and the server are communicated through a network. The physical signs monitored by the physical sign monitoring module include pulse waveform, heart-rate values, blood oxygen values and blood vessel microcirculation parameters.
