Problems solved by technology
However, the above-mentioned technologies all use the method of setting a fixed alarm threshold for monitoring. Due to the different layout positions and detection sensitivities of different detectors, it is easy to cause the fire to be formed due to the delay when the alarm triggering conditions are met, resulting in missed The prime time to identify and extinguish fires has been lost, often leading to disasters, causing loss of property and people

The invention discloses a fire early warning method and an early warning system. The method comprises the following steps: acquiring real-time data acquired by a fire detector in a monitored target area; outputting a preliminary early warning result of the monitored target area according to the similarity between the real-time data collected by the fire detector and the stored historical fire data; and outputting a final early warning result based on the condition that the same type of early warning results continuously appear in the preliminary early warning results. According to the technical scheme provided by the invention, the problems of low accuracy and high time delay of a traditional fire alarm method are solved.
Description
technical field [0001] The invention relates to the field of fire safety, in particular to a fire early warning method and an early warning system. Background technique [0002] Fire is one of the most destructive accidents that may occur. If the fire is not detected in time, it will cause immeasurable damage to public property safety and personal safety. Therefore, timely early warning of fire can avoid the damage caused by fire to the greatest extent. Fire early warning is usually monitored by fire detectors such as smoke sensors and temperature sensors. Traditional fire early warning technology sets a fixed alarm threshold for fire detectors such as smoke sensors and temperature sensors. If the signal collected by any single sensor exceeds the alarm threshold, then Trigger the fire alarm signal and start the automatic fire extinguishing system. This method has a high probability of causing false fire alarms. Then, in order to avoid a single sensor failure or false alarm,...
