Description

Technical Field

[0001] The present invention belongs to the technical field of fire protection, and specifically refers to an intelligent fire warning and extinguishing system inside a building. Background Art

[0002] In terms of building fire safety, traditional technologies have significant deficiencies. At present, the fire protection system in a building is often composed of multiple relatively independent subsystems, lacking an effective integration and coordinated operation mechanism.

[0003] Common smoke alarm systems only trigger fire sprinklers when a certain concentration of smoke is detected. They are single-function and passive, and cannot issue early warnings before a fire occurs, such as when the electrical system is abnormally heated, or when lines are aged and produce trace amounts of smoke. Fire alarm buttons can usually only trigger broadcast alarms for evacuation notifications after being manually pressed, and cannot actively monitor fire risks and prevent them in advance. The monitoring system mainly focuses on security monitoring, such as the safety protection of personnel and objects, and does not pay enough attention to fire safety testing. It is difficult to accurately identify signs of fire risks in the picture, such as abnormal heating of electrical equipment, the initial appearance of small flames, etc., and it is impossible to effectively integrate monitoring information into the fire warning system.

[0004] The electrical system monitoring is disconnected from other fire protection systems, and its monitoring data of electrical parameters cannot be shared and comprehensively analyzed with smoke alarm, monitoring and other systems, making it difficult to detect and warn of fire hazards caused by electrical failures at an early stage. Each system operates independently, and information transmission is not smooth, and it is impossible to form an organic whole to conduct all-round, multi-level real-time monitoring and analysis of fire risks. This decentralized fire protection system is difficult to achieve efficient and accurate early warning and fire extinguishing linkage when faced with complex and changeable fire situations, and cannot meet the growing demand for fire safety in modern buildings. The present invention aims to break down the barriers between such systems, build a highly integrated and intelligently coordinated fire warning and fire extinguishing system, and comprehensively improve the fire protection efficiency of buildings. Summary of the invention

[0005] In order to solve the problem of insufficient information transmission and response speed of traditional fire protection systems in the above-mentioned prior art, the present invention proposes an intelligent fire warning and extinguishing system inside a building, which can accurately detect fires, provide efficient warnings, and effectively and quickly extinguish fires.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is as follows: an intelligent fire warning and fire extinguishing system inside a building, comprising a monitoring image detection module, an electrical data monitoring module, a manual alarm module, an environmental monitoring module, an intelligent analysis and warning module, a risk elimination module and a fire extinguishing execution module, wherein:

[0007] The monitoring image detection module is used to connect with the existing monitoring system in the building, regularly obtain the real-time monitoring images of each area for image detection, and identify whether a fire has occurred;

[0009] The manual alarm module is provided with fire alarm buttons distributed in various areas of the building. When a person in the building discovers a fire, pressing the fire alarm button can directly send an alarm signal to the intelligent analysis and early warning module;

[0010] The environmental monitoring module is equipped with sensors for detecting fire in each room and passage in the building, including smoke sensors, infrared sensors, and temperature sensors. The environmental monitoring module transmits the data collected by these sensors to the intelligent analysis and early warning module to assist it in fire risk judgment and early warning;

[0011] The intelligent analysis and warning module receives and comprehensively analyzes the data from the monitoring image detection module, the electrical data monitoring module, the manual alarm module and the environmental monitoring module, evaluates the risk of fire occurrence and determines whether a fire has occurred, sends a fire risk warning signal to the risk elimination module when the risk of fire occurrence is assessed to be high, and sends a fire confirmation warning signal to the fire extinguishing execution module when it is determined that a fire has occurred;

[0012] The risk elimination module is used to notify staff to go to the fire risk area to eliminate the risk after receiving the fire risk warning signal;

[0013] After receiving the fire confirmation warning signal, the fire extinguishing execution module starts the corresponding fire extinguishing device and performs the fire extinguishing operation according to the specific situation of the fire, including controlling the water spraying of the sprinkler system, starting the gas fire extinguishing device, and commanding the fire-fighting robot to perform the fire extinguishing operation.

[0014] Furthermore, the monitoring image detection module includes a timing acquisition submodule, a positioning submodule, an image detection submodule and a fault detection submodule, wherein:

[0015] The timed acquisition submodule is used to set the time interval for acquiring surveillance images at a fixed time. The time interval parameters can be flexibly adjusted according to different areas, different time periods and security requirements of the building, and the surveillance images of each surveillance camera are acquired from the surveillance system according to the set time;

[0016] The positioning submodule quickly determines the specific location coordinates of the fire location in the building by obtaining the camera number corresponding to the monitoring screen and combining it with the installation location information of each camera pre-recorded by the monitoring system in the building, and transmits it to the intelligent analysis and warning module;

[0017] The image detection submodule performs image detection on the acquired image and uses image recognition technology to determine whether there is fire in the image. If fire is detected, the relevant information and image data are transmitted to the intelligent analysis and warning module;

[0018] The fault detection submodule monitors the working status of each surveillance camera in real time. If a surveillance camera fault is detected, resulting in a missing feedback image, a warning message is immediately issued. The warning message is transmitted to the relevant monitoring management terminal and the intelligent analysis and early warning module to timely troubleshoot the monitoring fault.

[0019] Furthermore, the electrical data monitoring module includes a data acquisition submodule and an abnormal feedback submodule, wherein:

[0020] The data acquisition submodule uses sensors to respectively collect different parameter data of the circuit of the electrical system, and the sensors include voltage sensors, current sensors, circuit on / off sensors, and temperature sensors;

[0021] When the abnormality feedback submodule detects data abnormality, it will feed back the data and the installation position of the corresponding sensor to the intelligent analysis and early warning module; the data abnormality includes: voltage and current values ​​higher or lower than the normal range, abnormal circuit disconnection, and temperature higher than the safety threshold.

[0022] Furthermore, the intelligent analysis and early warning module includes a data fusion submodule, a fire risk assessment submodule and an early warning signal generation submodule, wherein:

[0023] The data fusion submodule fuses the data transmitted from the monitoring image detection module, the electrical data monitoring module, the manual alarm module and the environmental monitoring module to form a unified analysis data set;

[0024] The fire risk assessment submodule uses an intelligent algorithm model to conduct a multi-dimensional assessment of fire risk based on the fused data, taking into account factors such as the probability of fire caused by electrical faults, the correlation between abnormal phenomena in the monitoring screen and fire, smoke concentration in environmental monitoring data, infrared radiation abnormalities, and temperature rise; fire risk is divided into five levels, namely no abnormality, low risk (abnormal electrical data, missing monitoring screen), environmental abnormality (temperature sensor detects high temperature, the smoke sensor detects smoke), open fire (monitoring identifies flames, people in the building press the fire alarm button), and large fire (monitoring identifies a large fire, or the temperature sensor detects a high temperature, and the smoke sensor identifies thick smoke), thereby assessing the risk of fire and determining whether a fire has occurred;

[0025] The warning signal generation submodule generates corresponding warning signals according to the fire risk assessment results and different risk levels, and sends a fire risk warning signal to the risk elimination module when the fire risk is assessed to reach the "low risk" level or above, and sends a fire confirmation warning signal to the fire extinguishing execution module when it is judged to reach the "open flame" level or above.

[0026] Furthermore, the risk elimination module includes a personnel information management submodule, a risk analysis and positioning submodule, and a task dispatching submodule, wherein:

[0027] The personnel information management submodule stores the identity information, contact information and duty information of the staff, including detailed information of firefighters and maintenance personnel of various equipment (such as electricians, monitoring equipment maintenance personnel, etc.);

[0028] The risk analysis and positioning submodule analyzes the fire risk warning signal, confirms the location and risk type of fire risk, and accurately locates the area where the risk source is located by deeply analyzing the data transmitted by the intelligent analysis and warning module, combined with the layout information of the building and the distribution of equipment, and determines the risk type, which includes electrical failure risk, environmental abnormality risk (temperature sensor detects high temperature, the smoke sensor detects smoke) and monitoring abnormality risk (such as the lack of monitoring images that may indicate regional hidden dangers);

[0029] The task dispatch submodule selects corresponding staff from the personnel information management submodule to eliminate the risk according to the risk location and risk type determined by the risk analysis and positioning submodule; if it is an electrical fire risk, electricians with relevant qualifications and experience are given priority; if it is a related risk of missing monitoring images, monitoring system maintenance personnel are dispatched; the task dispatch submodule sends risk information and dispatch instructions to the communication terminal of the selected staff to ensure that they can obtain task details in time and go to handle it; the task dispatch submodule will also track the progress of task execution and staff feedback information, and adjust task arrangements or send additional personnel to assist in time.

[0030] Furthermore, the fire extinguishing execution module includes a fire fighting device control submodule, a fire fighting resource allocation submodule and a fire fighting effect evaluation submodule, wherein:

[0031] The fire-fighting device control submodule activates different fire-fighting devices according to the fire situation;

[0032] The fire extinguishing resource allocation submodule allocates fire extinguishing resources in the building, such as the supply and distribution of fire water, the replenishment of fire extinguishing gas, and the dispatch of fire fighting robots;

[0033] The fire extinguishing effect evaluation submodule determines the degree of fire reduction according to the monitoring data and sensor feedback information during the fire extinguishing process (temperature sensors and infrared sensors detect temperature changes, and monitoring images detect changes in flame size), and evaluates the fire extinguishing effect in real time so as to adjust the fire extinguishing strategy in time.

[0034] Furthermore, it also includes an emergency communication module, which includes an internal communication submodule, an external rescue contact submodule and an information broadcast submodule, wherein:

[0035] The internal communication submodule establishes an emergency communication network inside the building to ensure that fire warning information and fire extinguishing instructions can be transmitted between various system modules, equipment and staff in a timely and accurate manner;
