Mattress-type sleep monitoring and warning device

The invention provides a mattress-type sleep monitoring and warning device, which mainly comprises a sensor unit, a monitoring unit and a remote control unit, wherein the sensor unit is composed of a mattress, a liquid capsule arranged inside the mattress, a liquid conduit connected with the liquid capsule, and a piezoelectric sensor at the tail end of the conduit; the monitoring unit is composed of a signal processing circuit, a storage and a signal transmission circuit; and the remote control unit is composed of a wireless transmission circuit, a signal processing circuit, a displaying and controlling panel and a sound-light alarming device. Change of liquid pressure in the mattress is caused by breathing, heartbeat and body movement of a user; the pressure change information is induced by the piezoelectric sensor, so as to generate corresponding electrical signals; electrical signals are processed by the monitoring unit to form respiratory signals and heartbeat signals by dividing; and when the user stops breathing or heartbeat of the user is abnormal, acousto-optic warning is given out by the remote control unit to remind watchers.
