In this embodiment, the fire fighting device 130 may be configured to perform fire extinguishing and fire fighting treatment on the target area in response to the abnormal detection result of the first type detection device 110; and performing an exhaust fire control process on the target area in response to the abnormality detection result detected by the second type detection device 120.
In this embodiment, if it is known from the detection results of the first type detection device 110 and the second type detection device 120 that there is a risk of fire or the like in the target area, the fire fighting treatment for the target area may be a fire fighting treatment. If it is known from the detection results of the first type of detection device 110 and the second type of detection device 120 that there may be a risk of toxic gas or the like in the target area, the fire fighting treatment for the target area may be an exhaust treatment, a ventilation treatment or the like.

The double detection equipment provided by the embodiment detects the target area, so that whether the target area is safe or not can be determined more accurately, corresponding fire-fighting measures are carried out based on more accurate detection results, and the safety of the target area is improved.
Consider the case of a target area where smoke, a target class of gas, is present that may cause the detection equipment installed within the target area to fail. In order to better enable detection of the target area, the fire protection system 100 also functions better. As shown in fig. 3, the fire protection system 100 may also be configured with a third type of mobile detection device 140 for detecting environmental data of the target area.
The third type of detection device 140 may not be installed in the target area. The third type detection device 140 is a movable device, and when the third type detection device 140 needs to be used, the third type detection device 140 is moved to a range capable of detecting the environmental data of the target area, so as to detect the environmental data of the target area.
In this embodiment, the fire fighting device 130 may be further configured to perform fire fighting treatment on the target area in response to the abnormality detection result detected by the third type detection device 140.
Considering that the target area has different potential safety hazards under the condition of different functions, when the target area has fire hazards, fire extinguishing or smoke extinguishing treatment is needed for the target area. Based on this, as shown in fig. 2, the fire apparatus 130 may include a fire extinguishing apparatus 131.
The fire extinguishing apparatus 131 may be configured to perform fire extinguishing treatment on the target area in response to an abnormal detection result of the first type detection apparatus 110 detecting that smoke exists in the target area. The fire extinguishing apparatus 131 may be configured to perform fire extinguishing treatment on the target area in response to an abnormality detection result that the first type detection apparatus 110 detects that the concentration of smoke of the target area is greater than a safe value.
For example, if the first type of detection device 110 detects that smoke is present in the target area, or the smoke concentration in the target area is greater than a specified value, it may indicate that there is a risk of fire in the target area. In this case, the fire extinguishing apparatus 131 may be activated to reduce the concentration of smoke in the target area, and intervene in the environment of the target area in advance to improve the safety of the target area.
Alternatively, the fire extinguishing apparatus 131 may be a gas fire extinguishing apparatus for performing fire extinguishing treatment on the target area by spraying a specified gas to the target area.
The specified gas may be, for example, heptafluoropropane or the like, which can be used for fire extinguishment.
In some implementations, one or more gas fire suppression devices may be provided on top of the target area, and when the first type of detection device 110 detects that smoke is present in the target area, or the smoke concentration in the target area is greater than a specified value, the one or more gas fire suppression devices on top are activated to eject fire suppressing gas to prevent the target area from catching fire.
Alternatively, the fire extinguishing apparatus 131 may be a liquid fire extinguishing apparatus for performing fire extinguishing treatment on the target area by spraying a specified liquid to the target area.

In this embodiment, the fire extinguishing system 100 may be provided with both a gas fire extinguishing apparatus and a liquid fire extinguishing apparatus, or may be provided with only a gas fire extinguishing apparatus. The number and types of the fire extinguishing apparatuses 131 may be appropriately configured according to the size of the scene of the target area. For example, the larger the target area, the more fire suppression devices 131 may be deployed; the smaller the target area, the fewer fire suppression devices 131 may be deployed.
Considering that the target area has different potential safety hazards under the condition of different roles, when the target area has toxic gas hidden hazards, the target area needs to be subjected to toxin expelling treatment. Based on this, as shown in fig. 2, the fire apparatus 130 may include an exhaust apparatus 132.
The exhaust device 132 may be configured to perform an exhaust treatment on the target area in response to the second type detection device 120 detecting that the target area has the abnormal detection result of the target type gas. The exhaust device 132 may also be configured to perform an exhaust treatment on the target area in response to the second type detection device 120 detecting that the target area has an abnormal detection result that the concentration of the target type gas is greater than the safe value.

The temperature detection device may be an infrared sensor by which the temperature of the target area is detected. The temperature sensor may be any other device capable of detecting temperature, such as a thermometer.
For example, the target area may be provided with a detection window, and the infrared sensor may detect temperature data of the target area through the detection window.
For example, when the temperature of the target area is detected to be too high, which indicates that the target area may be in risk of fire, the fire extinguishing device 131 in the fire extinguishing device 130 may be activated to perform a temperature-reducing fire extinguishing process on the target area.
Alternatively, the environmental data may include gas data; the third type of detection device 140 may include a gas detection device for detecting gas data of the target area.

Of course, the gas detection device may also integrate the functionality of the first type of detection device 110 and the second type of detection device 120.
In order to facilitate moving the third type of detection device 140, and the third type of detection device 140 may better enable detection of the target area, a mounting bracket may be configured for the third type of detection device 140.
The mounting bracket may be a movable, rotatable, retractable bracket, for example. When the third type of detection device 140 is required to be used, the mounting bracket can be moved to move the third type of detection device 140 mounted on the mounting bracket to a place to be detected, and the target area can be detected by the third type of detection device 140.
For example, the angle of the mounting bracket may be adjusted to drive the third type of detection device 140 to adjust the detection angle to better detect the target area.
Through the supplementary detection of the third type of detection device 140, the inspection result of the target area can be more comprehensive and reliable, and the fire protection device 130 can better cope with potential safety hazards possibly existing in the target area, so that the safety of the target area is improved.

Alternatively, the plurality of fire apparatuses 130 may be uniformly distributed on the top inside the test box 200. For example, if different types of fire apparatuses 130 are included in the plurality of fire apparatuses 130, the different types of fire apparatuses 130 may be alternately arranged at the top inside the test box 200.
In this embodiment, the third type of detection device 140 of the fire protection system 100 may be disposed outside the test box 200. To facilitate the detection of the third type of detection device 140 within the test box 200, as shown in fig. 4, an inspection window 210 may be provided on the test box 200.
