The invention provides a sleeping control device and method. The device at least comprises a mobile side, a
detector and a cloud side
server, is used for determining theoretical sleeping state information corresponding to body signals based on a preset
database through a sleeping analysis
algorithm, and is characterized in that the cloud side
server completes the correction and demonstration process of the theoretical sleeping state information on the basis of the before-sleeping feeling, after-sleeping feeling, actual sleeping state information and / or external condition information input by the user through the mobile side, and the mobile side is configured to retrieve the actual sleeping state information and related information stored in the cloud side
server and / or the mobile side through self-definition keywords, external conditions and / or physical features by the user. By making the sleeping feeling of the user related to the actual sleeping state of the user, the personalized sleeping state guiding can be more effectively conducted, and the ability of controlling the sleeping state by the user is trained and improved.
