the monitoring center judges the weight of the carbon dioxide fire extinguisher and the weight of the dry powder fire extinguisher in the data log respectively at set values, if the weight of the carbon dioxide fire extinguisher and the weight of the dry powder fire extinguisher in the data log are not in the set values, the monitoring center sends a carbon dioxide fire extinguisher leakage warning or a dry powder fire extinguisher over warning and specific position information of a corresponding fire box in a building to a mobile phone of an operator on duty in a short message mode for early warning.
9. The method as claimed in claim 8, further comprising the steps of:
the rotary camera acquires images of the carbon dioxide fire extinguisher and the dry powder fire extinguisher in the fire box in real time, and sends acquired image information to the monitoring center through the radio communication module, and the monitoring center displays an image picture acquired by the rotary camera;
the operator on duty judges the mechanical structure state of the carbon dioxide fire extinguisher and the dry powder fire extinguisher through the image picture displayed by the monitoring center, if the mechanical structure of the carbon dioxide fire extinguisher and the dry powder fire extinguisher is in a bad state, the operator on duty judges that the fire box is positioned at the specific position in the building by inquiring the data log sent by the radio communication module in the fire box, so that the operator on duty can timely drive the site for processing;
if the person on duty finds that the angle part of the image picture displayed by the monitoring center is right or not clear enough, the person on duty can use the monitoring center to send a control signal to the driving module through the radio communication module, and then the driving module is controlled to drive the rotary camera to rotate so as to adjust the angle of the rotary camera for collecting the image.
