Public lavatory refers to a lavatory that provides services to the public in public places. However, the space of the public lavatory compartment is narrow and closed, and when an accident occurs in the lavatory compartment, the public lavatory lacks corresponding early warning and coping measures.

The existing public toilet basically adopts a conventional door lock device, and accidents occurring in the toilet cannot be known from the outside. For example, chinese patent publication No. CN204960564U discloses a door lock system for an environmentally friendly portable toilet, in which an LED manned display screen is mounted on a door of the portable toilet so that a person outside the toilet can directly see whether or not a person is present in the toilet.

Chinese patent publication No. CN108868503A discloses a toilet door automatically locked in a manned state, in which electromagnetic induction and ampere's theorem are mutually matched to provide instant magnetization by instantly generated current, and like poles repel each other to realize a self-locking effect, so that the toilet door is suitable for users who forget to lock the door.

Nowadays, China gradually advances into the aging society, and a series of diseases such as osteoporosis and cardiovascular diseases caused by physiological aging of the old increase the accidents of the old when using the toilet. Particularly in public places where the elderly are moving outside. For example, in an old people living room (such as an old chess and card room, an old exercise place, an old gathering park, etc.), the problem that the old people accidentally fall down and fall down in a public toilet compartment, are not timely rescued, and miss the optimal rescue time often occurs.

Currently, no simple, convenient and effective danger early warning and alarming device specially aiming at the public toilet environment exists. Meanwhile, on one hand, how to reduce the cost and the detection energy consumption in the public toilet environment and reduce the false alarm probability are considered, so that social public resources are better utilized; on the other hand, in public restroom environments, the detection in the restroom compartment needs to take into account the protection of the public privacy.

B. Time determination whether to initiate a primary early warning response:

when the person in the toilet compartment still leaves the toilet without opening the door for more than the preset 'first safe time' (60 minutes in the embodiment), the color of the interior of the door lock is displayed as yellow, and the yellow light flickers and emits a slight buzzing to remind the person in the toilet.

B1 if the person in toilet presses the cancel button, it is determined that no accident has occurred, the internal yellow alarm is cancelled, and the timing module counts again.

B2 if the person in toilet does not cancel the yellow warning at this time, it is considered that there is a possibility of danger in the interior of the toilet compartment, and the color display outside the door also turns yellow, and the yellow light flashes.

C. If other waiters outside the door or toilet management/cleaning personnel find the yellow early warning and press the detection button, the intelligent detection module on the toilet door starts intelligent judgment and detection.

D. If the toilet is warned for a period of time, the personnel in the toilet are not cancelled or safely come out, and the preset second safety time (120 minutes in the embodiment) is exceeded, the intelligent judgment detection is started.

E. When the intelligent determination detection is started, the infrared sensing matrix of the intelligent detection module records the posture data of the user. The infrared induction internal data which induces the user is set to 1, and the infrared induction internal data which does not induce the user is set to 0. Wherein the processor concludes whether the person falls or not, in combination with the now existing, published data set about falls of the person, based on the matrix arrangement of 1 and 0 and the ratio of 1. If the accident happens, starting the secondary alarm response, if the accident happens, canceling the alarm and timing again,

F. after the secondary alarm response is started, the door is automatically opened and a distress signal is immediately sent to the police station/hospital near the public toilet.
