[0048] Smoke sensors, heat sensors, and flame detectors were deployed on various floors and in functional areas of the building. These sensors are connected to the control terminal via wired or wireless means to collect environmental data in real time and transmit it to the control terminal.

[0049] Additional GPS positioning, wind speed, wind direction, and air humidity detection modules were deployed to provide more comprehensive environmental information.

[0050] Deployment of early warning and alarm modules:

[0051] Audible and visual alarm devices were installed in the building's public areas and key locations. When the control terminal analyzes abnormal environmental data, these alarm devices will automatically trigger, emitting clear audible and visual signals to alert personnel to evacuate.

[0062] Image recognition module deployment:

[0063] High-definition cameras were deployed at key locations within the building to capture on-site video images. These cameras are connected to a control terminal, sending the image data to an image recognition module for intelligent analysis.

[0064] The image recognition module uses the image processing library of the OpenHarmony platform to identify key information such as the location of the fire source and the evacuation of personnel, and sends the analysis results to the control terminal and remote monitoring center.

[0065] System startup and initialization:

[0066] After the system starts up, each functional module automatically initializes to ensure it is in optimal working condition. The control terminal begins receiving environmental data from various sensors and performs real-time processing and analysis.

[0067] Fire warning and response:

[0068] When a sensor detects abnormal environmental data, such as excessive smoke concentration or rising temperature, the control terminal will immediately trigger an early warning signal and issue a local alarm through an audible and visual alarm device.

[0069] At the same time, the system sends alarm information to the remote monitoring center, and the fire department responds quickly and dispatches fire brigades to the scene.

[0070] Execute module actions:

[0071] Based on the results from the data processing and analysis module, the control terminal sends instructions to the execution module. For example, when the fire risk level is determined to be high, the automatic fire extinguishing device will be activated to perform fire extinguishing operations.

[0072] Smoke exhaust fans and emergency lighting equipment will also turn on automatically upon command, providing clear evacuation routes and sufficient lighting.

[0073] User interaction and manual control:

[0074] Firefighters can view system status, receive warnings and alarms through a user interface, and manually control the system by inputting commands as needed. For example, they can manually start or stop a fire extinguishing device.

[0075] Image recognition and decision support:

[0076] High-definition cameras capture real-time video images of the scene and send them to an image recognition module for intelligent analysis. The recognition results provide crucial information such as the location of the fire source and the evacuation status of personnel, offering strong support for firefighters' firefighting and rescue operations.

[0077] This intelligent fire protection system based on OpenHarmony can accurately warn of fire risks, respond quickly, and effectively control the fire.
