Research On Image Fire Alarm System

This thesis focuses on the tunnel environment, video-based intelligent fire detection fire alarm system design process of issue records, also made of the core algorithm improvements. To make paper found in the integrity and logic of the close, the paper carried out some technical content of the original reference, also designed a pilot program to demonstrate the feasibility of the design prototype. Articles in the recognition algorithm based on simulated data, the flame image recognition algorithm the advantages and disadvantages, and there is background interference in the case of the identification results, and finally integrated in the data, put forward the flame detection to improve sensitivity, reduce Fire alarm false alarm rate, it is best to mix the two algorithms for integrated design.The main subject of the design of the tunnel fire flame content of the video image recognition algorithm principle to explain, in the image based on this type of fire detector prototype design, the paper's visual characteristics from the flames of fire starting, fire is discussed in detail the process mechanism, and the fire flames on the frame in image sequence signal characteristics are analyzed in detail and in reference to the basis of these features to complete the mathematical model and identification algorithm design through MATLAB simulation, the simulation results of the validation these recognition algorithm is correct and effective. In the back of paper from the hardware and software to describe the image-based fire detection system works: by CCTV color camera for image extraction and transmission, and then through the identification of DSP algorithms, the system can be set by the state fire response time frame video sequences obtained have fires, while allowing the fire fire alarm control record information and shown in the surveillance system inside the tunnel where the fire of the screen.Paper also discusses the design of a pilot program to verify the theory about the accuracy and reliability of reporting systems and stability.However, as the engineering prototype verification system requires a lot of equipment and tools, and no related products can refer to, but due to time constraints, not writing papers before been validated engineering data. However, the tunnel project on the participation of relevant data to conduct the experiment can achieve good results, so you can believe that this design is feasible.
