Description

Technical Field

[0001] The present invention relates to the technical field of fire early warning and disposal, and in particular to a fire early warning and rapid disposal system based on wireless communication and management. Background Art

[0002] In the field of fire warning and disposal technology, traditional fire warning and disposal systems have many shortcomings.

[0003] From the perspective of communication technology, some traditional wireless communication methods are not very secure and are prone to information leakage during data transmission. For fire protection systems, data security is related to the safety of life and property. Information leakage may lead to the theft or tampering of key fire protection information, making the system unable to perform its warning and disposal functions normally, and delaying the best time for fire rescue.

[0004] In terms of system architecture, the traditional system architecture has poor flexibility and is difficult to adapt to the diverse needs of buildings or regions of different sizes. When facing large-scale venues such as large commercial complexes and industrial parks, it is impossible to easily expand the system to achieve full coverage; when applied in small venues, there may be a waste of resources and lack of the ability to flexibly adjust according to actual conditions.

[0005] In terms of equipment deployment and maintenance, traditional systems have difficulties in equipment connection and wiring. For example, point-type fire detectors have a limited monitoring range and require a large number of deployments to achieve monitoring of a certain area, which not only increases costs but may also result in blind spots. Moreover, traditional wiring methods are complex and difficult to construct in some special environments (such as ancient buildings and complex terrain areas), and signal transmission is susceptible to interference and attenuation, resulting in high equipment installation and maintenance costs and cumbersome maintenance work.

[0006] The timeliness and effectiveness of fire extinguishing response also need to be improved. Traditional fire extinguishing devices often have slow response speeds and are difficult to quickly control fires in the early stages of a fire. Some systems are unable to accurately monitor and quickly respond to different areas. When a fire occurs, the corresponding fire extinguishing equipment cannot be activated in time, causing the fire to spread and cause greater losses.

[0007] In order to better solve the above problems, we propose a fire warning and rapid disposal system based on wireless communication and management. Summary of the invention

[0008] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a fire early warning and rapid disposal system based on wireless communication and management.

[0011] Preferably, the regional control unit host includes a data storage module, a data analysis module, an early warning decision module, and a fire extinguishing equipment control module.

[0012] Preferably, the regional control unit host also includes an emergency rescue equipment dispatching module and a personnel evacuation guidance module.

[0013] Preferably, the emergency rescue equipment dispatching module dispatches emergency rescue equipment according to information such as the location and scale of the fire using geographic information system technology, plans the best rescue route and tracks the location and status of the equipment in real time; the personnel evacuation guidance module issues evacuation instructions and guidance information through the broadcasting system, electronic display screens and other equipment in the building, and uses the intelligent lighting system to provide emergency lighting in the evacuation passage and guide personnel evacuation by flashing lights.

[0014] Preferably, the data storage module uses a large-capacity database server to store various types of data transmitted from the temperature-sensing cable detector and the fire-prevention start monitoring module in real time.

[0015] Preferably, the data analysis module adopts big data analysis technology and artificial intelligence algorithm and combines historical fire data, environmental parameter data and various data transmitted from the temperature sensing cable detector and the fire prevention start monitoring module to establish a fire prediction model, predict the possibility of fire occurrence and development trend, and at the same time perform abnormal detection on the data of the temperature sensing cable detector and the fire prevention start monitoring module. The early warning decision module determines that a fire has occurred or is about to occur based on the results of the data analysis module, formulates an early warning plan, determines the early warning level, and sends different types of early warning information to relevant departments and personnel to initiate an emergency plan. The fire extinguishing equipment control module is connected to the ultra-fine dry powder automatic fire extinguishing device. After receiving the fire early warning signal, the ultra-fine dry powder automatic fire extinguishing device is automatically started to extinguish the fire according to the instructions of the early warning decision module, and the operating status of the ultra-fine dry powder automatic fire extinguishing device is monitored in real time.

[0016] Preferably, the regional control unit host is powered by a fire power supply, and the fire power supply adopts V alternating current.

[0017] Preferably, the fire prevention start monitoring module includes a fire sensor and an environmental parameter sensor.

[0018] Preferably, the fire sensor is used to collect smoke concentration, temperature, flame characteristics in real time and convert them into electrical signals, and the environmental parameter sensor is used to collect humidity, wind speed, air pressure in real time and convert them into electrical signals.

[0019] Preferably, the fire sensor and the environmental parameter sensor are both equipped with a wireless transmission unit, and the fire sensor and the environmental parameter sensor are both provided with a self-diagnosis and self-adaptive adjustment function module.

Compared with some traditional wireless communication methods, it has significantly improved security performance, which is particularly important for the field of fire protection system that has extremely high security requirements. At the same time, this distributed architecture design allows the system to be flexibly expanded according to actual needs, and the number of regional control unit hosts can be easily increased or decreased to meet the fire warning and disposal needs of buildings or regions of different sizes, thereby improving the versatility and adaptability of the system;

[0022] 2. In the present invention, the LoRa communication module has the characteristics of long distance and low power consumption, which enables the deployment of devices such as temperature-sensing cable detectors and fire-prevention start-up monitoring modules in a larger area without having to consider wiring and signal attenuation issues, thereby reducing the cost and difficulty of system installation and maintenance. At the same time, the low power consumption characteristic prolongs the service life of the equipment and reduces the workload of frequent battery replacement or maintenance. Each fire-prevention start-up monitoring module can be connected to an ultra-fine dry powder automatic fire extinguishing device, which can achieve accurate monitoring and rapid response to different areas. Once a fire occurs in a certain area, the corresponding fire-prevention start-up monitoring module can quickly start the ultra-fine dry powder automatic fire extinguishing device to extinguish the fire, thereby improving the timeliness and effectiveness of fire extinguishing.

[0023] 3.

When the temperature reaches the set threshold, the temperature-sensing cable detector can send out a fire warning signal in time. Compared with some traditional point-type fire detectors, the temperature-sensing cable detector has a wider monitoring range and can detect fire hazards earlier;

[0024] 4. In the present invention, compared with some battery-powered systems, the 220V AC power supply is more stable and reliable, and can ensure the stability of the system during long-term operation. At the same time, the fire power supply, as a power supply specifically for providing power for fire-fighting equipment, has higher safety and reliability, ensuring that the system can work normally when a fire occurs.
