Sleep sign state detection device

The utility model provides a sleep physical sign state detection device. The sleep physical sign state detection device comprises a bed body, a terminal carrier and a sensing belt used for detecting physical sign signals. The terminal carrier is fixed on one side of the bed body and comprises a signal processing device and a signal transmitting device which are connected with each other; a first end of the sensing belt is fixedly connected with the terminal carrier, and a second end of the sensing belt is movably connected with one side, back to the terminal carrier, of the bed body; wherein the sensing belt is in signal connection with the signal processing device through the signal transmitting device; when the second end of the sensing belt is connected with the side, back on to the terminal carrier, of the bed body, the sensing belt is transversely laid on the upper surface of the bed body. When the sensing belt detects a physical sign signal, the sensing belt transmits the physical sign signal to the sig
