For the target channel, i.e., the first road 91, in this embodiment, a predetermined channel, all of the passageways within the entire monitored cell 90, which are capable of running fire trucks, may be part of the road, for the way of setting only part of the roads as target channels, these target channels are required to be able to reach any point where a fire may occur, i.e. at least to reach the fire-fighting access points of any building of the monitored cell 90, the arrangement position of the cameras 3 is preferably arranged in a redundant manner on the basis of the principle that they can fully cover the target channels, and the arrangement of the intelligent street lamp 4 can meet the illumination requirement, and can be along the traveling direction of the target passage, at the position of the smart street lamp 4 on the previous pole, the light emitted by the indicating unit of the smart street lamp 4 on the next pole can be seen as a basic principle, and a redundant arrangement is preferably adopted. In the present embodiment, all the channels, i.e. the road sections with their middle lines represented by dashed lines in fig. 1, are used.
For the congestion information of the target access, in order to divide the target access into different target road segments according to a predetermined rule, and compose the congestion information of the whole target access by using the congestion information of the different target road segments, in this embodiment, the division rule is specifically to divide the target access into different target road segments by using the intersection of two roads as a node, as shown in fig. 1, for example, by using the intersection 910, 911, 912 as a node beside the No. 5 building, the target road segments 913, 914, 915, 916, 917, 918, and 919 can be divided, if the divided target road segments include more than two fire-fighting access points, the divided target road segments are further divided into corresponding sub-target road segments according to the fire-fighting access points, for example, fire-fighting access points 811, 812, 813, and 814 of No. 2 building, No. 3 building, No. 4 building, and No. 5 building are laid on the target road segment 918, therefore, the target road segment 918 is further divided into 5 target road segments, 9180, 9181, 9182, 9183 and 9184 respectively, and a camera 3 is required to be arranged at the junction of the target street lamps. Of course, other division rules may be used for division to reflect the unblocked status of the target passage in the monitored cell 90, that is, the target passage can reach those positions but cannot reach those positions, specifically, whether the target passage can reach the position of the fire-fighting equal altitude point of the building corresponding to the fire point.
Acquiring the blocking information on the target road section, specifically acquiring an image acquired by a camera 3 fixed on a lamp post corresponding to the intelligent street lamp 4 through image processing; the image processing step comprises the steps of acquiring a plurality of images aiming at the same scene at different time points, and identifying the position of a channel occupying object according to the plurality of images. The specific method is to adopt the technical scheme disclosed by the prior art such as the background technology patent literature and the like. The following method may also be adopted, in which a reference background image that is shot in advance and stored in the memory 222 is used to perform image recognition on target images acquired at different time intervals by using a background method, to acquire an occupied object on a road, and according to photos shot at different time points, whether the occupied object is a moving object is judged, if the occupied object is a moving object, the occupied object is not considered to be an occupied object, the reference background image is a photo shot without any occupied object on a channel, a specific processing method is to acquire a gray level image of the reference background image and a subsequently acquired image, then a difference is obtained between gray level values of pixel points of the subsequently processed image and the reference background image, and an absolute value is taken, then, an image frame after the difference is subjected to binarization processing based on a preset threshold, and then two colors of white and black represent the background and the occupied object. For the images obtained by subsequent photographing, segmentation can be performed according to an edge recognition algorithm and the road dentition of the road as a boundary, and partial images of the road are reserved as subsequent analysis objects.
A path construction step S2 of constructing a standby fire passage path that can be cleared from the target passage entrance of the monitored cell 90 to the fire point, based on the location information and the congestion information of the fire point.
Acquiring blocking information of different target road sections in a road network in the monitored cell 90, and constructing a continuously arranged candidate path which can be unblocked from a target channel entrance to a fire point by utilizing the target road sections in an unblocked state; and screening more than one path from the paths to be selected as standby fire fighting access paths.
As shown in fig. 1, the smoke detector 13 of the 10005 room of floor 3 in which the smoke detector 13 is installed is triggered by smoke. At this time, the fire-fighting access 816 and 817 of the monitored cell 90 are used as planning starting points of the route, and the route reaching the fire-fighting equal altitude point 812 of the building No. 3 has the fire-fighting access 816, the node 910, the link 915, the link 9180, the link 9181 and the link 9182 which are connected in sequence to form the route 1, or the fire-fighting access 816, the node 910, the link 915, the node 911, the link 919, the node 912, the link 9184 and the link 9183 which are connected in sequence to form the route 2, or the fire-fighting access 817, the link 916, the node 911, the link 919, the node 912, the link 9184 and the link 9183 which are connected in sequence to form the route 3, or the fire-fighting access 817, the link 916, the node 911, the link 9180, the link 9181 and the link 9182 which are connected in sequence to form the route 4.
The route which can be cleared to the fire-fighting equivalent altitude 812 is screened out according to the congestion information of the road section, for example, it is judged that the road section 9180 constitutes a congested road section because a large truck or a small car is parked thereon for a long time, and at this time, only the route 1 and the route 3 constitute the candidate route.
The specific method for screening the paths of the standby fire fighting passageways from the paths to be selected includes the following methods, and the selection can be carried out according to specific conditions, and of course, the selection can also be carried out according to other rules.
(1) According to the shortest route principle, more than two routes are screened out from the routes to be selected, the shortest route is used as a current standby fire fighting access, and the other routes are used as standby fire fighting accesses, such as screening routes 1 and 3, because the inlet of the route 1 is positioned beside the side of the large road and close to the coming direction of a fire fighting team, the route 1 is used as the current standby fire fighting access, and the route 3 is used as the standby fire fighting access.
(2) And along the wind direction at the fire point, screening channel paths close to the fire point from the downstream side of the fire point from the candidate paths, taking the shortest path as a current standby fire fighting channel, taking the other paths as standby fire fighting channels, and acquiring the wind direction of the other paths as standby fire fighting channels in an image recognition mode or a wind vane sensor mode, wherein the wind direction of the selected paths is blown from the 3 rd building to the 2 nd building, so that the path 1 and the path 3 meet the requirements, and at the moment, the path 1 is taken as the current standby fire fighting channel, and the path 3 is taken as the standby fire fighting channel. For the image identification mode, the image of the side surface of the building No. 3 acquired by a camera arranged at a fire-fighting ascending point 812 is taken as a reference image, the image of the previous time is taken as an image to be processed, the gray values of the two images converted into the gray map are subtracted, the absolute value is obtained, binarization processing is carried out again, image information with smoke is acquired, and the wind direction is judged according to the image information of the smoke acquired twice.
