| description | The utility model discloses an intelligent fire prevention method and system of an elevator. The temperature parameter, the smoke parameter, the lateral displacement parameter and the accelerated speed parameter of the elevator are monitored through a sensor in real time. When the temperature parameter and the smoke parameter are higher than standard parameters, a control device sends out an alarm signal for caution, an extinguishment signal is sent out for extinguishment, and meanwhile a power supply is switched off. Before a fire happens, the elevator abnormally operates in general, it is shown that the elevator shakes or the operating speed is abnormal, and therefore the lateral displacement parameter and the accelerated speed parameter of a car are monitored. When the lateral displacement angle of the car exceeds a limiting value or the accelerated speed exceeds a limiting value, the control device pre-judges that the fire is about to happen, the standard parameters of temperature and smoke in a server ca |
