Fire alarm grading early warning system based on Internet of Things

Abstract

The invention provides a fire alarm grading early warning system based on the Internet of Things. The system comprises a quantitative flammable gas sensor, a temperature sensor, a central processing unit and an Internet-of-Things module; the quantitative flammable gas sensor is used for detecting the concentration of flammable gas in the environment; the temperature sensor is used for detecting the temperature of a monitored object; the central processing unit is used for conducting operation according to the concentration of the flammable gas and the temperature to predict a possible fire situation and conducting grading early warning according to the emergency degree of the abnormal temperature change; the Internet-of-Things module is used for combining the quantitative flammable gas sensor, the temperature sensor and the central processing unit into an Internet-of-Things cloud platform. The system achieves the effect of taking preventive measures under an intelligent algorithm by collecting the abnormal concentration change of the the flammable gas in the data operation environment of the corresponding sensors and the abnormal temperature change of the monitored object and conducting grading early warning according to the emergency degree of the abnormal changes.

Description

technical field [0001] The invention relates to the field of fire alarm early warning, in particular to a fire alarm graded early warning system based on the Internet of Things. Background technique [0002] The prior art generally uses a combustible gas sensor to detect the concentration of combustible gas in the environment. When the concentration reaches a certain threshold, the horn is directly driven to use a high-decibel sound alarm; limited to the place where the incident occurred. In addition, the existing technology obtains the ambient combustible gas concentration to reach a certain concentration threshold and alarms, but cannot detect the change process of gas concentration, or detect the smoke generated by combustion or fire to alarm, and cannot determine in advance whether the environment has reached the temperature trend of combustion and The specific amount of combustible gas is used to comprehensively predict and alarm. At the same time, the alarm is limited...

In addition, the existing technology obtains the ambient combustible gas concentration to reach a certain concentration threshold and alarms, but cannot detect the change process of gas concentration, or detect the smoke generated by combustion or fire to alarm, and cannot determine in advance whether the environment has reached the temperature trend of combustion and The specific amount of combustible gas is used to comprehensively predict and alarm. At the same time, the alarm is limited to the local area and cannot be effectively and quickly transmitted to relevant personnel and related departments.
