Description

Technical Field

[0001] The present invention belongs to the technical field of fire protection, and relates to a laboratory intelligent fire protection system based on visual positioning and sensor detection, and a method for extinguishing fire by using the laboratory intelligent fire protection system based on visual positioning and sensor detection. Background Art

[0002] In traditional laboratory firefighting scenarios, firefighting relies primarily on manual operation of fire extinguishers. Operators need to be physically close to the fire, exposing themselves to an extremely dangerous environment. In many cases, traditional firefighting methods have a slow response time, and it takes a significant amount of time from the moment a fire is discovered to the moment the operator retrieves the fire extinguisher and rushes to the fire site. In environments like laboratories, many materials and equipment are extremely sensitive to the spread of fire. A short delay can cause the fire to spread rapidly, resulting in irreparable damage.

[0003] Existing fire detection systems mainly rely on temperature and smoke alarm sensors, and use sensor data to determine whether a fire has occurred. However, due to the influence of factors such as the sensor's own accuracy and the environment, the detection results will be inaccurate to a large extent, delaying the best time to extinguish the fire. For laboratory equipment, the inability to accurately locate the fire source and fire situation will cause the fire to spread, which will affect the remaining intact equipment and cause unnecessary losses.

[0004] For example, a Chinese patent discloses a fire protection system with intelligent fire protection equipment [application number: 201910927423.0], which includes a fire pump, a microcontroller, a sensor device, a wireless module, a server, a mobile terminal, a fire control center and an intelligent fire protection equipment. Although this invention patent can use the infrared sensor in the intelligent fire protection equipment, the detection element will convert the infrared radiation detected and received into a weak voltage signal, which will be amplified by the field effect tube installed in the probe and output to the outside. After detecting that a person is passing or nearby, it will be converted into an electrical signal and sent to the single-chip microcomputer. The single-chip microcomputer stores the information in a memory. At the same time, the single-chip microcomputer reads the location information and GPS positioning information pre-stored in the memory and sends it to the server through the SIM module. During the rescue process, the firefighters can use the mobile terminal to check in real time whether there are people near the intelligent fire protection equipment. At the same time, they can check the specific floor location of the intelligent fire protection equipment and carry out targeted rescue of people remaining on the floor where the fire occurred.

[0005] However, the above-mentioned problem of being unable to accurately locate the fire point and accurately extinguish the fire at the fire point still exists. Summary of the Invention
