Abstract

The invention discloses an infrared thermal imaging fire detection alarm system, relates to a fire detection alarm system and aims to solve the problem that the conventional fire detection is low in real-time property. The infrared thermal imaging fire detection alarm system comprises a master control center, N front-end image acquisition units and M branch control centers, wherein the N front-end image acquisition units are distributed in an area to be monitored; the master control center, N front-end image acquisition units and M branch control centers are accessed to a local area network; and each front-end image acquisition unit perform 24-hour image acquisition by employing a charge coupled device (CCD) camera and a thermal infrared imager. The infrared thermal imaging fire detection alarm system is suitable for fire detection alarm in a forest management area.

Description

technical field [0001] The invention relates to a fire detection and alarm system. Background technique [0002] Most countries monitor the occurrence of forest fires by using monitoring methods such as satellite cloud images or aerial forest protection. However, satellite cloud images are often limited by time, and it is impossible to monitor the fire process in real time, and the cost of aerial forest protection is high. [0003] Forest fires are characterized by suddenness, randomness of disasters, and huge losses in a short period of time. Therefore, once a fire occurs, rescue measures must be taken at an extremely fast speed. Whether the rescue is timely depends mostly on whether the forest fire behavior is discovered in a timely manner, whether the analysis is accurate and reasonable, and whether the decision-making measures are appropriate. It is an inevitable trend in the development of forest fire prevention management to use advanced technology and high-tech mean...
