Problems solved by technology

However, my country's current "Code for Fire Protection Design of Buildings" (GB50016-2006) does not provide for the installation of automatic fire alarm systems for residential buildings.
Through research, it is found that the existing smoke detectors are prone to failure, disconnection or battery damage, lack of battery undervoltage detection, false alarms, and extremely unstable work

Abstract

The invention relates to the technical field of fire control, and specifically relates to a household smoke alarm based on a single-chip microcomputer. The smoke alarm based on a single-chip microcomputer is composed of a data acquiring and processing unit, a single-chip microcomputer and an output unit, wherein the data acquiring and processing unit and the output unit are connected with the single-chip microcomputer. The smoke concentration value of the environment is displayed directly through a liquid crystal display, so that users or people rushing to the site can directly know the smoke concentration value of the environment and make better and more appropriate judgment and treatment, and the function of smoke detection is achieved. The smoke alarm of the invention has the advantages of simple structure, accurate test results, convenient use and easy promotion.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to a household smoke alarm based on a single-chip microcomputer. Background technique [0002] In recent years, there have been 6 to 7 million fires worldwide each year, of which residential fires account for more than 80%. According to the statistical report "Smoke Alarms for Home Fires in the United States", it is found that for every 1,000 reported fires, if there are smoke alarms and wet sprinklers, the death rate caused by fires can be reduced by 84%. The installation of home fire alarm systems has already been promoted and implemented in foreign countries, and many countries strictly implement them with corresponding laws and regulations. However, my country's current "Code for Fire Protection in Building Design" (GB50016-2006) does not provide for the installation of automatic fire alarm systems in residential buildings. Through research, it is found that the existi...
