[0003] Currently, in order to continuously monitor the fire-fighting status, it is necessary to perform time-sharing image capture and processing of the fire-fighting scene. However, since the content of each frame of the fire-fighting scene output in time is different, the enhancement algorithms required to obtain the best image quality are also different. How to match the optimal enhancement algorithm for different fire-fighting scene content is one of the technical problems that need to be solved at present. Summary of the invention

[0005] According to the present invention, a fire extinguishing management system is provided, the system comprising: The linkage control mechanism is respectively connected to the fire extinguishing actuator and the visual acquisition mechanism provided on the fire-fighting vehicle to realize the synchronous linkage control of the fire extinguishing nozzle direction of the fire extinguishing actuator and the visual acquisition direction of the visual acquisition mechanism; A visual acquisition mechanism, connected to the linkage control mechanism, for performing visual acquisition of the fire extinguishing scene near the fire fighting vehicle under the drive of the linkage control mechanism, so as to obtain and output a corresponding fire extinguishing scene image; An analysis and processing mechanism is arranged on a fire truck and connected to the visual acquisition mechanism, comprising an information extraction device, a parameter measurement device and a network application device, wherein the network application device is respectively connected to the information extraction device and the parameter measurement device, and the analysis and processing mechanism is used to obtain the resolution of the received fire extinguishing scene image, the number of foreground pixels and the brightness values corresponding to the pixels, and simultaneously obtain the signal-to-noise ratio and contrast of the fire extinguishing scene image, and use a BP neural network model after completing multiple learning to intelligently identify the maximum noise amplitude of the processed image obtained after the fire extinguishing scene image is enhanced using the enhancement algorithm based on the algorithm mark data corresponding to the enhancement algorithm used, the resolution of the fire extinguishing scene image, the number of foreground pixels and the brightness values corresponding to the pixels, and the signal-to-noise ratio and contrast of the fire extinguishing scene image; An amplitude comparison mechanism, connected to the analysis and processing mechanism, is used to use the enhancement algorithm corresponding to the smallest maximum noise amplitude among the maximum noise amplitudes obtained by the BP neural network model after multiple learning by various enhancement algorithms as the target enhancement algorithm; A picture playing mechanism, arranged inside the fire truck and connected to the amplitude comparison mechanism, for enhancing the fire extinguishing scene image using the target enhancement algorithm to obtain a dynamic enhanced picture for on-site playback; Among them, various enhancement algorithms include histogram equalization enhancement algorithm, logarithmic image enhancement algorithm, exponential image enhancement algorithm and high contrast preservation enhancement algorithm.
[0006] It can be seen that the present invention has at least the following four significant substantive features: Substantive feature A: Introducing a customized analysis and processing mechanism including an information extraction device, a parameter measurement device and a network application device, wherein the network application device is connected to the information extraction device and the parameter measurement device respectively, thereby providing necessary hardware resources for analyzing the optimal enhancement algorithm; Substantive feature B: obtaining the resolution of the received fire-fighting scene image, the number of foreground pixels and the brightness values corresponding to each pixel, and obtaining the signal-to-noise ratio and contrast of the fire-fighting scene image, and using the BP neural network model after completing multiple learning to intelligently identify the maximum noise amplitude of the processed image obtained after the fire-fighting scene image is enhanced using the enhancement algorithm based on the algorithm mark data corresponding to the enhancement algorithm used, the resolution of the fire-fighting scene image, the number of foreground pixels and the brightness values corresponding to each pixel, and the signal-to-noise ratio and contrast of the fire-fighting scene image; Substantive feature C: The enhancement algorithm corresponding to the maximum noise amplitude with the smallest value among the maximum noise amplitudes obtained by the BP neural network model after multiple learning is used as the target enhancement algorithm for various enhancement algorithms, thereby completing the intelligent analysis of the best enhancement algorithm for the fire extinguishing scene image; Substantive feature D: A linkage control mechanism is adopted on the fire-fighting vehicle to realize the synchronous linkage control of the direction of the fire-extinguishing nozzle of the fire-extinguishing actuator and the field of view acquisition direction of the visual acquisition mechanism, wherein the coverage angle of the direction of the fire-extinguishing nozzle of the fire-extinguishing actuator is the same as the coverage angle of the field of view acquisition direction of the visual acquisition mechanism, and the field of view acquisition action of the visual acquisition mechanism is only performed during the fire spraying process of the fire-extinguishing nozzle of the fire-extinguishing actuator.
[0007] The fire extinguishing management system of the present invention is intelligently designed and logically compact. Since various enhancement algorithms can be respectively adopted as the target enhancement algorithm, the enhancement algorithm corresponding to the smallest maximum noise amplitude among the maximum noise amplitudes obtained by the BP neural network model after multiple learning is used, thereby completing the intelligent analysis of the best enhancement algorithm for the fire extinguishing scene image.
