Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] Such as figure 1 As shown, the present invention provides a fire alarm security system based on ultraviolet and image detection technology, the system includes: monitoring site equipment and monitoring computer equipment. The monitoring site equipment includes: monitoring cameras, set up in multiple places that need to implement security monitoring, in order to take images of the monitored areas; ultraviolet data analysis modules, arranged near each monitoring camera, in order to detect Ultraviolet radiation should be processed and analyzed to preliminarily judge whether there is a fire.

[0028] The monitoring computer equipment includes: a comprehensive analysis module that receives digital signals from the monitoring camera and the ultraviolet data analysis module, and when the ultraviolet data analysis module judges that there is a fire, the...

Abstract

The invention discloses a fire hazard alarm safety protection system and method based on a UV and image detection technology. Detected UV radiation data of a monitored area is received, the safety state of the monitored area is pre-determined, and whether UV waveband data carried by flames exist is determined; and image data of the monitored area and a UV data analysis results are received, when it is determined that the UV waveband data carried by the flames exist, the image data is identified, and whether a fire hazard is generated is determined. A UV detector and a monitoring pick-up head are compounded together, under a normal condition, the monitoring pick-up head only carries out normal safety monitoring work, and an image identification algorithm is not started for secondary determination unless the UV detector detects fire hazard signals. A two-stage fire hazard detection mechanism is employed, the correct rate of fire hazard identification is improved, useless calculation of a computer is also reduced, and waste of resources is avoided.

Description

technical field [0001] The invention relates to a fire alarm security system and method based on ultraviolet and image detection technology. Background technique [0002] With the development of urban buildings in the direction of high-rise and densification, the occurrence of fires is becoming more and more frequent, and the losses are also increasing. The importance of fire prevention and control is also becoming more and more obvious. [0003] As the core component of the fire alarm system, fire detectors have roughly experienced the development process from temperature detectors→smoke detectors→gas detectors→photosensitive detectors→video detectors. [0004] Traditional smoke, temperature, and gas detectors judge whether a fire has occurred by detecting smoke generated by combustion, changes in ambient temperature, and harmful gases. It has the disadvantages of limited space applicability, low sensitivity, and slow fire detection speed. [0005] Photosensitive detector...
