The specific embodiment
In order further to explain the technical solution of the utility model, the utility model is elaborated below by specific embodiment.
This is novel relates to a kind of fire water monitor automatic fire extinguishing system based on image flame location, as shown in Figure 1, comprise man-machine processing interface 1, central control processor 2, Multiplexing Image Grab Card 4 and some groups of regions module groups 3, these some groups of regions module groups 3 are arranged on respectively in the regional of a large space division, the group several border factually situation that arranges and deciding, every group of described regions module group 3 comprises core processing module 31, big gun body interlocking module 32 and camera 33.
The two-way electrical connection carried out with central control processor 2 in described man-machine processing interface 1, the equal two-way control end that is electrically connected to central control processor 2 of one control end of the core processing module 31 of each group, the two-way electrical connection of control end of another control end and the big gun body interlocking module 32 of organizing separately; The described camera 33 of each group is arranged on the top of the big gun body of the big gun body interlocking module 32 of group separately, and the described camera 33 of each group all is electrically connected to the input of Multiplexing Image Grab Card 4, and the output of this Multiplexing Image Grab Card 4 is electrically connected to the data input pin of central control processor 1.Core processing module 31 is mainly used in controlling the motion conditions of the big gun body of big gun body interlocking module 32 and feedback big gun body interlocking module 32, and big gun body interlocking module 32 mainly comprises big gun body and the accessories such as auxiliary this big gun body motion and detection and location.
Being divided into the processing of flame static nature and flame dynamic features on flame treatment processes, on the flame static nature is processed, can adopt the 8mm focal length, the CMOS simulation camera of 1/3 inch is as gathering image source, utilize the characteristics of flame static nature, flame distinguishes over other luminous object on wave band, by add the optical filter of specific band (corresponding flame wave band) on the sensor of simulation camera, the interference of other light emitting source of filtering realizes basic hardware handles.process for adopting host computer (being central control processor 2) to control on flame dynamic features, obtain image information by multi pass acquisition card 4 from the simulation camera, be transferred to host computer, further extract image information by directshow, utilize this Software of Computer Vision platform of VS2008 to realize the image processing in host computer the image information of extracting, then utilize the image processing function of opencv, utilize context update and mixed Gauss model further to remove the interference of all the other dynamic and non-burning things which may cause a fire disaster objects, for the flame image circularity, frequency, area change, the flame characteristics such as wedge angle feature, get rid of the interference that light source causes, utilize and expand, corrosion, realize guaranteeing the flame information integrity to methods such as growths from all directions, thereby separate flame information, the assurance follow-up work is processed.
during work, one-level fire alarm communication is to central control processor 2, worked by the camera 33 of each group regions module group 3 afterwards, and send the image information of gained to Multiplexing Image Grab Card 4, Multiplexing Image Grab Card 4 is sent to central control processor 2 with the relevant information of each group again, analyze and process by this central control processor 2 information that sends, in analysis is in certain or some zones, the condition of a fire is arranged, send corresponding control instruction to the core processing module 31 of corresponding group by central control processor 2, this group core processing module 31 is controlled big gun body interlocking module 32 after receiving instruction, pass through optocoupler, the force devices such as relay are controlled the big gun body and are moved up and down and spray water, finally realize flame location and accurately fire extinguishing.Described core processing module 31 can also feed back to central control processor 2 with the concrete posture information in the motion of big gun body, thereby IMAQ information and big gun body motion control situation all consist of Closed control, so that system accurately locates constantly flame and in time the pose of big gun body made adjustment.Described some groups of regions module groups 3 all are subjected to the unified control of central control processor 2, and this kind design makes whole system can bring into play the sharpest edges of detection, in time surveys and realizes the automatic scan positioning fire-extinguishing by the regions module group with regard near field.
Described camera 33 with each group is arranged on the top of the big gun body of the big gun body interlocking module 32 of group separately, the scope of fire extinguishing is the large space of the certain limit (for example 50m) centered by the big gun body, camera 33 its scanning fire extinguishings are divided into two steps, the first step is to carry out 360 ° of scannings with a low angle, if find burning things which may cause a fire disaster in scanning process, first the burning things which may cause a fire disaster abscissa is moved to the picture center, regulate again ordinate to the picture center, thereby make gun muzzle of big gun body aim at burning things which may cause a fire disaster, if do not find burning things which may cause a fire disaster, elevation angle carries out rescan; Second step is the setting height(from bottom) by gun muzzle angle that obtains and big gun body, calculates flame from the distance of big gun body, by the parabola compensation algorithm, realizes accurate sprinkling fire.
To sum up, this case fire water monitor automatic fire extinguishing system is specially adapted to detection and the fire extinguishing in large space, utilize cheap, use widely that monitoring camera obtains image information, then based on the quiet behavioral characteristics of flame, from scene, separate concrete flame information, obtain the concrete coordinate of flame kernel, and in conjunction with closed-system structure and multizone distribution design, realize excellent ground control precise positioning flame and accurate sprinkling fire automatically.
