A spraying fire-extinguishing method based on multi-fire probe linkage detection comprises the following steps:

s1, in any one spraying fire extinguishing node, a fire probe detects a fire signal in real time and transmits a detection result to a central processing unit;

s2, when the fire probe detects fire information, the central processing unit controls the camera to start, controls the fire extinguishing switch to close, and controls the first three-dimensional holder and the second three-dimensional holder to rotate, so that the detection direction of the fire probe and the shooting direction of the camera are opposite to a fire occurrence point, and the spraying direction of the fire extinguishing nozzle is opposite to the fire occurrence point;

s3, water from a tap water pipe flows to a third end of a second T-shaped connecting pipe 5 through a check valve 1, a control valve 2 and a first T-shaped connecting pipe 3, water in a water tank 4 flows to a first end of the second T-shaped connecting pipe 5 through a second electromagnetic valve 9, after being converged in the second T-shaped connecting pipe, the water is pressurized through a booster pump 6, and then flows to a spraying module through a first electromagnetic valve 7 to be sprayed and put out a fire;

s4, the central processing unit takes fire detection information from the fire probe, video image information from the camera and positioning information from the positioning module as fire signal acquisition results and stores the fire signal acquisition results in the storage module;

s5, uploading a fire signal acquisition result to a background monitoring server by the central processing unit through the wireless communication module;

s6, when receiving a fire signal acquisition result uploaded by the spraying fire-extinguishing node, the background monitoring server determines the position of a fire point according to positioning information contained in the fire signal acquisition result, displays the fire point on a GIS map of a fire detection area, and simultaneously displays video image information of the fire point for monitoring by workers;

s7, the background monitoring server sends a cooperative detection instruction to other spraying fire extinguishing units around the fire occurrence point, wherein the cooperative detection instruction comprises the position of the fire occurrence point and a detection control command; and displaying information returned by cooperative detection of other spraying fire-extinguishing nodes around the fire occurrence point to workers for the workers to judge the fire spreading degree, determining whether a fire-fighting task is generated according to a judgment result, and distributing the fire-fighting task to the fire-fighting workers through a background communication module when the fire-fighting task is generated.

When the spraying fire-extinguishing node uploads information to the background monitoring server, if the wireless communication module of the spraying fire-extinguishing node is disconnected with the background monitoring server, the information is transmitted to other spraying fire-extinguishing nodes in a networking communication mode, and then the wireless communication module of the other spraying fire-extinguishing nodes uploads the information to the background monitoring server.

In step S7, after the background monitoring server sends the cooperative detection instruction to the other spraying fire-extinguishing nodes around the fire occurrence point, the process of performing the cooperative detection on the other spraying fire-extinguishing nodes around the fire occurrence point includes:

for any spraying fire-extinguishing node around the fire occurrence point, after receiving a cooperative detection instruction, controlling a second three-dimensional holder in the fire detection device to rotate, so that a camera and a fire probe in the detection device are aligned with the fire occurrence point, and transmitting information from a positioning module, the camera and the fire probe to a background monitoring server by the spraying fire-extinguishing node;

in the step S7, when the staff determines the fire spreading degree according to the fire signal acquisition result of the fire occurrence point and the information uploaded by other surrounding spraying fire extinguishing nodes, if it is found that the fire is gradually reduced or extinguished under the action of the spraying fire extinguishing device, a fire fighting task does not need to be generated; and if the fire is still enlarged and cannot be effectively restrained, generating a fire fighting task.
