The invention relates to an electric bed attitude control system and a control method based on cloud computing. The system comprises a bed body terminal, an intelligent terminal, a cloud end database and a cloud computing server, wherein the bed body terminal, the cloud end database and the cloud computing server are connected to the intelligent terminal. According to the electric bed attitude control system provided by the invention, the bed body terminal can be used for comparing a command signal, which is transmitted from the intelligent terminal, with a recognition signal of the bed body terminal, so that movement attitudes of an electric bed are controlled, and attitude information of the electric bed is uploaded to the intelligent terminal; in addition, by virtue of the intelligent terminal, feedback signals can be transmitted to and stored in the cloud end database; meanwhile, by virtue of the cloud computing server, the attitude information, which is stored in the cloud end database, is read and user's using habits are analyzed so as to recommend optimum attitude data to a user for user's selection; and with the application of the electric bed attitude control system, current movement attitudes of the electric bed can be reflected in real time, so that the electric bed is controlled precisely and intuitively.
