Multi-heterogeneous alarm data integrated linkage fire extinguishing intelligent fire extinguishing system

Abstract

The invention relates to the technical field of fire extinguishing, and discloses a multi-heterogeneous alarm data integrated linkage fire extinguishing intelligent fire extinguishing system. The system comprises a fire alarm fire extinguishing linkage host, a fire sensing subsystem, a video alarm discrimination subsystem, an Internet of Things terminal input system, a fire linkage expansion cardand a water-based fire extinguishing subsystem; the alarm prevention and fire extinguishing linkage host is connected with the fire sensing subsystem, the video alarm discrimination subsystem, the Internet of Things terminal input system and the fire protection linkage expansion card, and the fire protection linkage expansion card is connected with the water-based fire extinguishing subsystem. According to the invention, a fire can be discovered in the early stage, false alarm of a detector can be avoided through the input of various alarm signals, the alarm authenticity can be remotely rechecked and discriminated through video monitoring, and on-site timely fire extinguishing can be realized through the design of the intelligent fire extinguishing integrated box.

Description

technical field [0001] The invention relates to the technical field of fire fighting and extinguishing, in particular to an intelligent fire extinguishing system for multi-heterogeneous alarm data integration and linkage fire extinguishing. Background technique [0002] Today, with the rapid development of science and technology, high-rise buildings and various household appliances continue to increase, power consumption continues to increase, and the probability of fires is also increasing year by year, endangering the personal safety of residents and causing immeasurable losses. Fire safety There is no delay in our work. In the face of fire, rescue is our last line of defense. What we need to do is to continuously strengthen fire awareness and focus on "prevention first, combining prevention and elimination" to effectively do a good job in fire safety. [0003] The traditional fire alarm in our country uses a wired temperature-sensing smoke detection system, which is gener...

AI Technical Summary

Problems solved by technology

[0004] 1. When a fire breaks out, the alarm will be issued only when the temperature above 65 degrees and thick smoke are felt. At this time, the ground temperature should be above 600 degrees. If the fire in the defense zone starts to burn from the outermost side, it will reach the ceiling detector The time required will be longer. At this time, the fire has spread in a large area, and the fire cannot be effectively controlled, resulting in greater personal and property losses;

[0005] 2. Due to the fear of false alarms from the temperature-sensing and smoke detectors, the central control room will generally send personnel to the scene to identify the authenticity of the fire, which again delays the time for fire rescue;

[0006] 3. When the alarm information reaches the central control room, if there is no on-duty personnel in the fire control room, or the firefighters are sleeping or playing games while on duty, the fire will continue to burn. There are many such cases;

[0007] 4. When the alarm information reaches the central control room, if there is a person on duty in the central control room, the person on duty will start the automatic sprinkler system. It will take at least 10-20 minutes from the start to the on-site sprinkler, and the fire cannot be controlled in time;

[0008] 5. Once the fire sprinkler system is started, it will continue to flow until there is no water in the pipe, resulting in the same fire and flood in traditional fire protection, forming a secondary disaster;

[0009] In order to solve the above problems, the country has promoted the Internet of Things alarm system, and the NB smoke alarm system and the LoRa smoke alarm system have appeared successively. It is found that the smoke can realize the alarm in seconds, but this kind of product that can detect fire in the early stage also has false alarms, It is impossible to review and identify the authenticity of the alarm and the defects of being unable to extinguish the fire. For this reason, we propose a smart fire protection system with multi-heterogeneous alarm data integration and linkage fire extinguishing
