An electric bed, comprising: a bed body, a plurality of bed planks, a wake-up device, a clock and a main control box (2). The main control box (2) is electrically connected to the wake-up device and the clock, and is applicable for storing a wake-up time. The electric bed further comprises a monitoring module (1). The monitoring module (1) comprises a processing module and a sensor, wherein the sensor is electrically connected to the processing module, and is applicable for monitoring whether a user has left the bed； if the sensor monitors that the user has not left the bed, the processing module activates the wake-up device when the wake-up time on the clock is due according to the stored wake-up time； and if the sensor monitors that the user has left the bed, the processing module does not activate the wake-up device when the wake-up time on the clock is due. The electric bed can automatically decide whether to perform the wake-up function, thereby improving the degree of intelligentization, and can further comprise a wireless communication module (3) for receiving the wake-up time and the wake-up mode set by an intelligent terminal, which increases the user's operation freedom.
