Building fire early warning and fire situation assessment system based on internet of things and method thereof

Abstract

The invention discloses a building fire early warning and fire situation assessment system based on the internet of things and a method thereof. Environmental information and electrical information closely related to occurrence of fire in the building are acquired through the building internet of things, feature extraction and data fusion are performed on the acquired information and fire early warning is performed on the building. The building information is acquired by using the building internet of things system, the information from multiple sensors is integrated, data analysis is performed by using the data fusion method and accurate and rapid early warning is performed on the fire situation of the building so that interference signals can be effectively filtered through weight calculation of multiple types of information, the uncertainty and the limitation of the single sensor can be overcome, and the fire early warning and forecasting accuracy of the building can be enhanced andthe fire situation can be effectively assessed.

Description

technical field [0001] The invention relates to a building fire early warning and fire situation assessment system and method based on the Internet of Things. Background technique [0002] With the continuous development of various buildings, the building scale is getting bigger and bigger, the level is getting higher and higher, and the building standards are getting higher and higher. The fire detector is the "sensory organ" of the system, and its function is to monitor whether there is a fire in the environment. Once there is a fire, the feature vector of the fire, such as temperature, smoke, gas, and radiation intensity, is converted into an electrical signal, and an immediate action is sent to the fire alarm controller to send an alarm signal. [0003] At present, commonly used fire detectors include smoke detectors, temperature detectors, special gas detectors, infrared flame detectors and ultraviolet flame detectors. The above-mentioned fire detectors only detect on...

Problems solved by technology

On the other hand, the existing fire alarm methods lack the assessment of the fire situation, and it is difficult to judge the fire development trend and the degree of harm (such as the number of people in the building where the fire broke out), which is not conducive to accurate and rapid rescue.
