Embodiment
[0019] Embodiment: the intelligent fire prevention method of elevator, this method specifically comprises the following steps;
[0020] (1) Real-time monitoring of the temperature parameters, smoke parameters, lateral movement parameters and acceleration parameters of the elevator by sensors; the temperature parameters and smoke parameters of the monitoring elevator are monitored by temperature sensors and smoke sensors arranged in the car and the shaft respectively; The lateral movement parameter of the monitoring elevator is monitored by a lateral inclinometer arranged on the outer wall of the car.
[0021] (2) Transmit the temperature parameters, smoke parameters, side movement parameters and acceleration parameters collected by the sensor to the control device, and the control device sends the above parameters to the display device, and compares the above collected parameters with the standard parameters stored in the server in real time Compared;
[0022] (3) When the la...

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.
Description
technical field [0001] The invention relates to an elevator, in particular to an elevator intelligent fire prevention method and system thereof. Background technique [0002] At present, with the continuous development of the attached elevator industry and the improvement of public safety awareness, the requirements for elevator fire safety are getting higher and higher. Now the fire protection measures of elevators are generally just to install temperature and smoke sensors in the elevator car. When it is detected that the temperature and smoke value reach the set value, the fire extinguisher will be automatically activated to extinguish the elevator car. Yet existing fire prevention method can only carry out fire extinguishing after fire takes place, and this moment fire has reached a certain level, and the fire extinguishing effect of fire extinguisher is not ideal. Therefore, how to predict the fire hazard before the fire hazard occurs, thereby reducing the difficulty o...
