Fire monitoring and automatic fire extinguishing system and working method thereof

Abstract

The invention discloses a fire monitoring and automatic fire extinguishing system and a working method thereof. The system comprises a fire source monitoring system, a monitoring center and an automatic fire extinguishing system. The method comprises the steps: through a far-infrared high-definition automatic zoom thermal imager and a visible light high-definition fog-penetrating camera of the fire source monitoring system, acquiring thermal imaging and visible light images of a mountain forest in real time; then, respectively meshing the thermal imaging and the visible light images, further judging whether a fire source point exists in each thermal imaging grid and each image grid or not through an algorithm; and if the fire source point exists in the thermal imaging and the image in thesame grid, determining that a fire occurs at the position, so that the fire position can be sent to the automatic fire extinguishing system for automatic fire extinguishing. According to the invention, when an early fire source occurs, the early fire source can be found in time and accurately positioned for early warning, and meanwhile, the fire source can be extinguished quickly after early warning to prevent the fire source from developing into a larger fire, so that the property loss is effectively reduced, and the time required for extinguishing the fire is shortened.

Description

technical field [0001] The invention relates to a fire monitoring and automatic fire extinguishing system and a working method thereof, belonging to the technical field of automatic fire extinguishing. Background technique [0002] Fire is one of the important disasters that cause personal injury. In many fields such as mountains, forests, petroleum, chemical industry, fire protection, prisons, military and many other fields, how to reduce the loss of fire to people and property, that is, how to find the early fire source and timely extinguish the fire is the key technical issues to be resolved. Among them, the occurrence of forest fires is often due to the untimely discovery. When the fire is discovered, the fire is already large, which makes it very difficult to put out the fire. A lot of people and property are invested, with little effect, and finally cause a large number of casualties and huge property losses. At present, the existing forest fire alarm system is genera...

Problems solved by technology

However, in this way, when an early fire occurs in the forest, because the smoke produced is less and the fire source point is small, the existing method of temperature measurement and smoke monitoring cannot find the early fire source, resulting in early detection and early warning. The fire source has developed into a larger fire; at this time, the emergency rescue plan is activated and personnel are organized to fight the fire, and it is no longer possible to quickly extinguish the fire; in addition, the existing fire extinguishing methods are mainly manual fire extinguishing, fire fighting robots plus water pumps or fire pumps firefighting station

These fire extinguishing needs manual participation in the whole process, resulting in the inability to timely extinguish the fire at a specific location after receiving the fire warning, and because the fire is large, it may also affect the safety of firefighters
