In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the embodiments described below are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

as shown in fig. 1, the present invention discloses an intelligent fire extinguishing system, which includes a plurality of temperature monitoring probes 100, a central controller 200 electrically connected to the plurality of temperature monitoring probes 100, and an intelligent fire extinguishing apparatus 300 communicatively connected to the central controller 200, wherein the temperature monitoring probes 100 are mainly composed of temperature sensors, and the plurality of temperature monitoring probes 100 monitor air temperatures within a range of nodes at corresponding positions and send temperature data of the nodes at corresponding positions to the central controller 200.

The central controller 200 records the position nodes where the temperature monitoring probes 100 are located to form a circulation path diagram including the position nodes, collects and monitors a plurality of temperature data of the temperature monitoring probes 100, and when the temperature data of one or a plurality of the temperature monitoring probes 100 are abnormal, the central controller 200 sends a cooling instruction or a fire extinguishing instruction to the intelligent fire extinguishing device 300 to control the intelligent fire extinguishing device 300 to move to the corresponding position nodes to extinguish or cool the fire or move to the corresponding position nodes in sequence according to the circulation path diagram to extinguish or cool the fire to each ignition point in sequence.

The central controller 200 includes an acquisition module 201, an analysis module 202, and an alarm module 203, which are electrically connected in sequence, wherein the acquisition module 201 acquires a plurality of temperature data monitored by the temperature monitoring probe 100, and transmits the temperature data to the analysis module 202.

The analysis module 202 is provided with a plurality of temperature threshold values corresponding to the temperature monitoring probes one to one, and the temperature data abnormality includes that the temperature data is located in the temperature threshold values and exceeds the temperature threshold values, specifically:

when the acquired temperature data is within the temperature threshold, the analysis module 202 analyzes and records the temperature data from each temperature monitoring probe 100, and sends a corresponding cooling instruction to the intelligent fire extinguishing apparatus 300, and the intelligent fire extinguishing apparatus 300 receives the cooling instruction, moves the corresponding position node, and reduces the temperature in the corresponding position node by spraying dry ice;

when the acquired temperature data exceeds the temperature threshold, the analysis module 202 immediately sends a fire extinguishing instruction to the intelligent fire extinguishing device 300, and similarly, the intelligent fire extinguishing device 300 moves to the corresponding position node to extinguish the initial fire of the corresponding position node in a dry powder spraying manner.

Through the setting of temperature threshold value for judge the temperature condition of the position node that a plurality of temperature monitoring probe 100 corresponds, when the position node temperature is in the temperature threshold value, cool down corresponding position node, and analysis module 202 can analyze the temperature data in the temperature threshold value of record, corresponding adjustment dry ice jet velocity and injection volume have greatly guaranteed the normal of corresponding temperature node temperature, have guaranteed promptly that the electrical apparatus is worked in normal operating temperature.

Correspondingly, when the temperature data is within the temperature threshold value or exceeds the temperature threshold value, the analysis module 202 sends early warning information or fire alarm information to the corresponding mobile phone and PC terminal through the alarm module 203, and meanwhile, the alarm module 203 sends out sound and light alarms to remind related personnel.

It should be noted that, when the temperature of the location node just rises to the corresponding temperature threshold, the central controller 200 immediately sends a corresponding instruction to the alarm module 203, but does not immediately send a cooling instruction or a fire extinguishing instruction to the intelligent fire extinguishing apparatus 300, and after analyzing the change curve of the temperature data in the corresponding temperature threshold, makes a corresponding judgment to avoid the occurrence of a misjudgment.

The intelligent fire extinguishing device 300 comprises a switching module 301 and a moving module 302, the switching module 301 is a three-way electromagnetic valve or other components with the same functions, the switching module 301 connects and communicates a spraying interface with a tank body for storing dry ice or dry powder according to a received cooling instruction or a received fire extinguishing instruction, and the moving module 302 is matched with a guide rail which is arranged, so that the stability and accuracy of the motion of the intelligent fire extinguishing device 300 are improved.

In addition, be provided with on the guide rail with a plurality of with the proximity switch that the position node corresponds, analysis module 203 shows that certain or more position nodes need when cooling down or put out a fire, control the contact switch-on power supply corresponding with the position node, when removal module 302 removed to the contact switch department of switch-on power supply, analysis module 202 monitored the contact switch disconnection to send corresponding instruction to intelligent extinguishing device 300, make intelligent extinguishing device 300 stop, and begin to cool down or put out a fire the operation to corresponding position node.

In addition, the intelligent fire extinguishing apparatus 300 further comprises a video monitoring module 304 connected with the mobile phone and the PC end in a wireless communication manner, wherein the video monitoring module 304 is used for shooting the field environment and transmitting the shot scene environment to the mobile phone and the PC end, so that the field environment can be known and analyzed remotely.

Just central controller 200 still include with cell-phone and PC end wireless communication connection's remote control module 204, intelligent extinguishing device 300 still include with remote control module 204 wireless connection's receiving module 303, cell-phone and PC end are passed through remote control module 204 with receiving module 303, personnel such as fire fighting watch the picture that video monitoring module 204 was shot on cell-phone and PC end, the condition such as conflagration at further analysis scene, and remote control intelligent extinguishing device 300 carries out more accurate removal, cooling and the operation of putting out a fire, not only is favorable to improving the efficiency of cooling and putting out a fire, and still can be through remote control intelligent extinguishing device 300, carry out work such as daily tour.
