Description
Technical Field
The invention relates to elevator safety equipment, in particular to a method and a device for preventing an elevator from accidents.
Background
Elevators are installed in high buildings at present, but in use, some accidents occur due to the carelessness of parents or the delay of the actions of elders. Individual children can take the elevator alone to leave the home door due to being not intelligible, and after the infants leave the home door, certain personal safety events occur. There is a media report, when old people in one year takes a grandchild, a child enters the elevator and presses a floor button first, but because the old people slow in movement, the elevator is closed and the child takes alone when the old people do not enter the elevator. Children cannot see adults and walk back and forth in the elevator, while old people are worried about waiting outside the elevator below, but the elevator cannot stop and return to the original floor. After the elevator arrives at the corresponding floor, the children do not know how to do the elevator due to sudden things, and the children go out of the elevator, go back in the elevator and finally go out of the elevator. While other younger relatives are also quickly coming to the elderly, contacting property and alarming, they can only urgently wait outside elevators and on other floors, looking for toddlers. When the infant comes and returns and does not find the adult, the infant alone runs beside the window in the floor corridor, and the infant is anxious to find the adult because the infant does not think about the danger outside the window, and the infant climbs out of the window, so that the life is lost. Therefore, the safety measures of the conventional elevator for the situations are not sound enough, and the safety is low.

if yes, sending the key signal to an elevator control device to control an elevator to run to a floor corresponding to the key signal;
if not, go to S2;
s2, the key signal comprises an elevator inner key signal and an elevator outer key signal, and whether the key signal only exists in the elevator or not is judged;
if not, judging that the key signal has an elevator external key signal, sending the elevator external key signal to an elevator control device to control the elevator to run to a floor corresponding to the elevator external key signal, and returning to S2;
if yes, judging that the key signal only has an in-elevator key signal, sending an alarm signal to an alarm, and sending the in-elevator key signal to an elevator control device to control the elevator to stop.
From the above description, the beneficial effects of the present invention are: when the situation that a key in the elevator is pressed down and a light curtain formed by the remote infrared transmitter and the remote infrared receiver is not shielded is detected, the situation that only infants possibly stay in the elevator alone exists, the elevator is controlled to stop at the moment and the alarm is controlled to give an alarm, the infants are prevented from staying to other floors along with the operation of the elevator alone and being separated from relatives, and therefore the situation of accidents is avoided, and the safety is improved.
Further, the step S2, if only the intra-elevator key signal is present, of transmitting the alarm signal to the alarm includes:
if only the key signal in the elevator exists, acquiring a pyroelectric infrared signal sent by a pyroelectric infrared sensor, and judging whether the elevator is occupied or not according to the pyroelectric infrared signal;
