The conventional fire detection is to detect the concentration of smoke and the concentration of gas generated by other combustion after the occurrence of the fire, and to alarm or automatically extinguish the fire after the detection reaches the concentration value of the fire (the fire water valve is opened to extinguish the fire), so that a problem exists in that the whole fire detection is performed after the occurrence of the fire rather than in that the fire is prevented, and the side surface has low efficiency of the whole fire detection, and the conventional fire detection needs to monitor the whole environment in real time so as to realize the fire detection (whether the fire is detected or not rather than whether the fire is possible). Secondly, along with the development of society, the electric fire caused by irregular electricity consumption of a user and ageing of an electric wire becomes one of the indispensable detection items for fire detection, but the gravity center of the existing mode is not in terms of how to detect the electric fire, but how to set a safety circuit to carry out tripping protection on a circuit so as to avoid the electric fire, so that an abnormal situation exists, namely the phenomenon that the electric fire is caused by the use of a large power for a long time after the user privately wiring cannot be avoided, and the protection circuit is arranged in all sockets and the socket to prevent the fire from happening based on the common technology, so that the production cost of the socket is greatly increased, and the problem that the protection circuit works inaccurately due to the ageing of the socket also exists. Based on the problems, a fire detection method is provided, so that the fire detection efficiency is improved.

The fire detection method is applied to a fire detection system, the fire detection system comprises a fire controller and a plurality of fire detectors, the fire controller is respectively connected with the plurality of fire detectors, and when environment acquisition information of the fire detectors is received, the fire detection method determines whether the environment acquisition information is matched with preset fire abnormality information or not, wherein the preset fire abnormality information comprises increment abnormality information and temperature point abnormality information; if the electric quantity information in the environment acquisition information is matched with the increment abnormal information, determining a detection control instruction based on the environment acquisition information; performing fire detection according to the detection control instruction and the environment acquisition information; if the temperature information in the environment acquisition information is matched with the temperature point abnormality information, determining a behavior detection instruction based on the environment acquisition information, and determining behavior detection information corresponding to the behavior detection instruction; if the behavior detection information is matched with the preset user operation behavior, fire detection is performed based on the behavior detection information, the acquired environment acquisition information is matched, further the increment abnormality information or the processing mode of the temperature point abnormality information is selected based on the environment acquisition information, fire detection is performed according to the detection control instruction and the environment acquisition information during the increment abnormality information processing, and fire detection is performed based on the behavior detection information when the temperature point abnormality information, so that the problem that the image acquisition equipment or the fire detection equipment is required to continuously detect images or other data of a target area in the prior art, and further the phenomenon that the whole detection system is required to continuously detect is avoided.

Based on the hardware structure, the embodiment of the fire detection method is provided.

An embodiment of the present application provides a fire detection method, referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of the fire detection method of the present application.

In this embodiment, the fire detection method is applied to a fire detection system, the fire detection system includes a fire controller and a plurality of fire detectors, the fire controller is respectively connected with the plurality of fire detectors, and the fire detection method includes:

step S10, if the environment acquisition information of the fire detector is received, determining whether the environment acquisition information is matched with preset fire disaster abnormal information, wherein the preset fire disaster abnormal information comprises increment abnormal information and temperature point abnormal information;

in this embodiment, when the environment collection information collected by the fire detector is received, it is determined whether the environment collection information is matched with the preset fire disaster abnormal information, and when the temperature information, the electric quantity information in the environment collection information are not matched with the temperature point abnormal information and the increment abnormal information in the preset fire disaster abnormal information, the step of receiving the environment collection information of the fire detector is continuously executed based on the normal operation, wherein the normal operation refers to the operation of executing the acquisition according to the period or the trigger factor. The preset fire disaster abnormal information at least comprises increment abnormal information and temperature point abnormal information, the environment acquisition information at least comprises temperature sensing and electricity consumption sensing information in the whole detection environment, the increment abnormal information is electricity consumption increment abnormal information in the whole environment, the temperature point abnormal information is temperature point abnormal information in the whole environment, and detection of electric fire and normal fire can be processed in a targeted manner through detection of the environment acquisition information, so that the fire disaster detection functionality and accuracy are guaranteed.

Referring to fig. 4, fig. 4 is a schematic view of a fire detection system, and the fire detection method of the present application is applied to the fire detection system of fig. 4, and the fire controller 100 may be a system-on-a-chip, and processes collected information of a fire detector (including at least a plurality of temperature detection cameras 400, person detection/monitoring cameras 300, smoke detector and power detector 200) and controls the fire detector to detect in a targeted manner. For example, for a building, smoke detector 1500-1 and smoke detector n500-n may be disposed at different exits of the ventilation duct or smoking and corridor, while temperature sensing camera 400 may be incorporated with person sensing/monitoring camera 300,The camera collects visible light and infrared thermal imaging double-channel monitoring, supports double-light fusion, can detect flames and smoke in real time and timely find primary fires and alarm at the same time, supports smoking behavior analysis and detection and timely early warning of illegal smoking in places such as warehouses, for example, a common household camera can support the function of temperature sensing, so that the cost of the whole fire detection system is greatly saved, various household cameras can be connected into the system to further realize the function of fire detection of the whole system, only the fire controller 100, the smoke detector and the electric quantity detector 200 are needed to be newly added, the electric quantity detector 200 can be arranged at the node of an electric wire, for example, a building is provided with 3 rooms, the electric quantity detector 200 can be connected into the places such as the warehouse through bus branches in the 3 rooms, and the maximum current in corresponding incremental abnormal information can be slightly changed along with time in order to avoid fire caused by the aging of the electric wire. In the following description of the entire system, it is assumed that the detection target is one room, when the fire controller 100 detects the temperature of the entire environment through the temperature detection camera 400, the electric quantity of the entire room is detected through the electric quantity detector 200 installed at the socket interface, or other positions, and the human detection/monitoring camera 300 mainly determines the time of the temperature detection, when there is a fire When a person does not act, the period of temperature detection is increased appropriately, and when a person does not act, the period of temperature detection is prolonged to the maximum, so that different detection periods can be set for different time periods for reasons of artificial cause or electric fire caused by fire. When the electric quantity detector 200 detects that the electric quantity increment is abnormal (the electric quantity increment reaches the current capable of triggering the fire) or the temperature detection camera 400 in the whole area detects that the temperature of one point in the room is greatly at the fire temperature, the electric quantity increment abnormality and the position of the one point in the room are determined, and then the corresponding temperature detection camera is driven by the temperature detection selector 410 to perform targeted detection, the fire controller 100 can not acquire other environment acquisition information (under the condition of normal period operation and no special factor triggering acquisition environment acquisition information) at this time, for example, the temperature detection camera 400-A in the area performs detection work, and other temperature detection cameras, for example, the temperature detection camera 400-M in the M area can be in a dormant state, so that the whole detection efficiency can be improved and the energy consumption can be reduced. When the fire situation is met by detecting the area, the smoke selector 510 is turned on to turn on the smoke detectors 1500-1 to n500-n in a polling manner, so that whether the fire situation is true can be determined, and because the smoke detectors are generally arranged at the ventilation openings, the smoke situation is easier to detect in the fire, and the fire detection accuracy is improved.

Step S21, if the electric quantity information in the environment acquisition information is matched with the increment abnormal information, determining a detection control instruction based on the environment acquisition information;

step S31, fire detection is carried out according to the detection control instruction and the environment acquisition information;

in this embodiment, when the electric quantity information in the environment collection information is matched with the incremental anomaly information, the detection control instruction is determined based on the environment collection information, and then the fire detection of the electric fire factor is performed according to the detection control instruction and the environment collection information. The electric quantity information can be current or instantaneous power flowing in the circuit, the detection control instruction refers to an instruction for performing targeted detection control on the environment, and finally, the specific position with fire risk is detected based on the detection control instruction and time information in the determined environment acquisition information, and the detection mode can be that the temperature is continuously increased or the current is continuously increased in a continuous period of time through a corresponding temperature camera, so that a fire alarm instruction is generated. The high current, the temperature and the high power duration can be properly reduced according to aging, so that the fire factor of electric fire can be accurately detected, and the detection efficiency can be improved by targeted detection when the existence factor of the electric fire is determined.

The temperature information refers to temperature information in the whole detection environment, for example, the temperature information is light red below 30 ℃, the temperature information is light red between 30 and 60 ℃, the temperature information is red between 60 and 110 ℃ and the temperature information is dark red above 110 ℃, so that an abnormal temperature region can be judged, a behavior detection instruction for controlling the region to detect is determined, the behavior detection instruction refers to an instruction for detecting the artificial behavior of the abnormal temperature region, namely, the behavior detection instruction refers to a command for controlling the person detection/monitoring camera to detect the behavior of a person in the corresponding region range, and the behavior detection information refers to the behavior of the person in the region within a specified time. And judging whether the behavior detection information is matched with a preset user operation behavior, if so, carrying out fire detection based on the behavior detection information, if not, detecting whether the temperature has a diffusion trend through the temperature detection camera, if so, generating a fire alarm instruction, and if not, only generating a prompt instruction to prompt the user. The user operation behavior refers to user operation behaviors such as cooking, ignition, smoking, ignition test of a smoke detector and the like, when the behavior detection information is not matched with the preset user operation behavior, the smoke detector at the corresponding position is started to perform smoke detection, so that the problem that the temperature of a specific point of a region is high but no fire phenomenon exists can be solved, for example, the temperature of hot water in a region with high air pressure can reach more than 100 ℃, the phenomenon of misjudgment caused by temperature factors can be avoided, and the accuracy of fire detection can be further ensured.

Further, a flow chart of a fire detection method is provided for this embodiment, referring to fig. 5, in this embodiment, after the fire controller obtains the collected information, it is determined whether the collected information is abnormal in increment or abnormal in temperature point, and when the collected information is not both, the step of obtaining the collected information is continuously performed, where the collected information refers to various collected information, such as electric quantity information, temperature information, character action information, and the like. When the increment is abnormal, a detection control instruction is determined, the target area is detected through the detection control instruction, the target area is detected for a period of time, whether the detected temperature reaches the temperature of fire or not is detected, the targeted detection of the target area is stopped when the detected temperature does not reach the temperature, and when the target area is determined to be the targeted detection area next time (the same area can be continuously used as the target area for a period of time, for example, one day), a user reminding instruction is generated, and the user is reminded. The detection control instruction refers to an instruction for controlling detection of a corresponding fire detector, and the target area refers to an area with abnormal increment.

For example, people have less flow at night, the problem that fire sources are brought into a detection area is generally avoided, the detection period can be properly prolonged, and resources can be saved greatly. When the person detection camera (the person detection/monitoring camera in fig. 4) is used for collecting the person information, and detecting whether the person behavior information exists in the person information, and when the person behavior information does not exist in the person information, the first electric quantity information collected by the electric quantity detector is obtained in real time, the first temperature information collected by the temperature detection camera is obtained at a first preset time threshold, and finally the first temperature information and the first electric quantity information are used as environment collection information.
