judging the fire level according to the acquired real-time image data;
and selecting a supply mode of the fire-fighting medium according to the obtained fire condition grade and the real-time liquid level data of the fire-fighting medium box.
In detail, the following contents are included:
s1: fire fighting water management strategy under normal state
Considering water consumption in non-fire situations such as natural evaporation, drilling, other operation and maintenance operations and the like, only a simpler water replenishing mode is adopted. Monitoring the water level of the water tank through a sensor, and adding water when the water level is lower than a set height in a non-fire mode; when the water level is higher than the set height, the water adding operation is stopped.
Because the problem that the water pressure and the water quantity of the fire hydrant influence the operation effect under the non-fire state does not need to be considered, an additional strategy does not need to be adopted.
Specifically, the default setting of the water level is: in normal mode, water is added when the water level is lower than half of the total height, and the filling is stopped.
S2: fire-fighting water management strategy under fire-fighting operation state
The management strategy thought in the state is 'core area priority'. When fire occurs in the transformer substation, a fire-fighting water management strategy in a fire state is adopted.
Firstly, analyzing image information through images acquired on site, studying and judging the fire condition on site, wherein the fire condition is divided into a large grade, a medium grade and a small grade, and the fire fighting water supply mode is divided into a random adding mode, a set line water adding mode and a warning line water adding mode.
When the large fire (the first level) is judged to exist at present, the robot collects images on site for analysis, and the fire-fighting medium supply equipment connected with the robot working on the large fire site adopts a random and random mode to ensure that the robot working on site can obtain continuous fire-fighting water;
if other robots working simultaneously exist, the fire-fighting medium supply equipment connected with the robots on the site with medium fire (second-level) can be added with water when the water level is lower than the set line (namely, the set line water adding mode); the robot on the small-scale fire (third-level) site can only add water when the robot is lower than the warning line (namely, the warning line water adding mode).
When the maximum fire on the site is the medium fire, the medium fire adopts a random-use random-addition mode, if other robots working simultaneously exist, the robot on the small fire (third level) site can add water when the temperature is lower than a warning line (namely the warning line water adding mode);
when the maximum fire on the site is a small fire, the robot on the site of the small fire (third level) can add water when the robot is lower than a warning line (namely a warning line water adding mode).
It is to be understood that, in other embodiments, the fire level may also be more, such as four levels or five levels or more, and the water adding mode may be expanded by setting a plurality of setting lines or warning lines, such as a first setting line water adding mode, a second setting line water adding mode, a first warning line water adding module, a second warning line water adding mode, and the like, which may be set by a person skilled in the art according to specific situations and will not be described herein again.
In this embodiment, in the fire fighting mode, the set water level of the set line water adding mode is lower than one fourth of the total height, and the water level of the warning line water adding mode is lower than one tenth of the total height.
The operation and maintenance personnel for water level setting can perform self-defined setting through background control, and the details are not repeated here.
In this embodiment, first, a flame region is marked in an acquired video image by a computer vision-based algorithm, as shown in fig. 2;
the marked region is generally determined by a corresponding empirical determination through a rectangular outer frame based on the variation of the area, the length-width ratio, the mass center fluctuation and the like of the rectangle.
Specifically, the method comprises the following steps: four vertexes of the rectangle are marked with coordinates A (a) from the upper left corner in a counterclockwise way 1 ，a 2 )，B(b 1 ,b 2 )、C(c 1 ,c 2 )、D(d 1 ,d 2 ) Then its length m = d can be obtained 2 -a 2 Width n = b 1 -a 1 Then, the length-width ratio K = m/n can be used as a more effective shape characteristic quantity for judgment;
meanwhile, different acquisition devices have different resolutions (which may cause different aspect ratios of the entire screen) and different focal lengths (which may cause different content amounts contained in the screen, that is, different proportions of the marked rectangles in the entire screen), so that the threshold values set for different feature amounts are different, and need to be adjusted according to the device types and experience.
By setting threshold values in different ranges, the size of the fire can be corresponding to the range of the threshold values.
It is understood that in other embodiments, the manual adjustment of the water replenishing mode may be selected, and the whole process of personnel participation is performed, and the result provided by the embodiment is only used as an aid for decision making.
