Abstract

The invention discloses an intelligent elevator fireproof method and system. A temperature parameter, a smoke parameter, a lateral-moving parameter and an acceleration parameter of an elevator are monitored in real time through a sensor, when the temperature parameter and the smoke parameter are higher than standard parameters, a control device sends out an alarm signal for warning and sends out an extinguishment signal to put out a fire, and a power source is cut off at the same time. Before the fire occurs, the elevator generally operates abnormally, for example, the elevator shakes or is abnormal in operation speed, so that the lateral-moving parameter and the acceleration parameter of a lift car are monitored, when the lateral-moving angle of the lift car is beyond the limit value or the acceleration speed is beyond the limit value, the control device prejudges that a fire is about to happen, the control device can lower the standard temperature parameter and the standard smoke parameter of a server, the trigger difficulty of an extinguishment device is lowered, the extinguishment device can be started when or before the fire happens, and safety is greatly improved.
