Abstract

A fire alarm control method and system of a smart city. The method comprises the following steps: receiving first image data sent by a camera (101); obtaining coordinates of the camera corresponding to the image data when the number of people in the first image data exceeds a set threshold (102); obtaining complete second image data in the vicinity of the coordinates, analyzing chromaticity of the second image data, and if the analysis result indicates that a smoke chromaticity range exceeds a set range, marking the coordinates as a fire alarm (103). The technical solution has an advantage of smartly controlling fire alarms.

Description

Fire alarm control method and system for smart city

Technical field

The invention relates to the field of communication and intelligent cities, and in particular relates to a fire alarm control method and system for a smart city.

Background technique

Smart city construction is a systematic project. In the smart city system, first of all, urban management is intelligent, and the smart city management system assists in managing the city, followed by intelligent infrastructure including intelligent transportation, intelligent power, intelligent buildings, and intelligent security, including smart medical care, smart home, and intelligence. Social intelligence such as education and intelligent production of intelligent enterprises, intelligent banks, and smart stores will comprehensively improve the modernization level of urban production, management, and operation. Smart city is a fusion of information economy and knowledge economy. The computer network of information economy provides construction wisdom. The basic conditions of the city, while the human brain wisdom of the knowledge economy turns human wisdom into the kinetic energy of urban development. Professor Ji Zhu, Director of the World Economic Research Center of Beijing Technology and Business University, presided over the completion of China's first urban intelligent management system ——Beijing Urban Intelligent Management System” (BCSMS). On this basis, the “China Economic Intelligence Management System” (CESMS), which was designed by Professor Ji Zhu, was officially launched in January 2011. The economy has been included in the intelligent management track. In 2011, the World Economic Intelligence Early Warning System (WESFS) will also be put into operation, and Beijing has become the world's smart economy center.

The existing city's control of fire alarms is mainly based on the control of individual fire alarms, and it is impossible to achieve automatic intelligent control.
