Therefore, the present invention has significant technical advantages and social benefits and is worthy of promotion and application in the field of fire safety in charging stations.

[0121] In summary, the implementation process of the intelligent charging station fire early warning alarm system and method is as follows:

[0122] (I) Workflow of the early warning system:

[0123] 1. Data collection and preprocessing

[0124] The starting point of the early warning system is data collection. Intelligent sensing units, including temperature sensors, smoke detectors, flame recognition cameras, combustible gas sensors and other high-precision devices, are deployed at key locations in the charging station to collect key parameters such as ambient temperature, smoke concentration, flame signs, and combustible gas concentration in real time. These data are transmitted to the data processing and analysis module via wired or wireless means.

[0125] During the data preprocessing stage, the system will clean, denoise, and correct the received raw data to ensure the accuracy and reliability of the data. At the same time, it will reasonably estimate or interpolate the missing data to ensure the data integrity for subsequent analysis.

[0126] 2. Risk assessment and model prediction:

[0127] The preprocessed data is sent to the data processing and analysis module for in-depth analysis. This module uses advanced machine learning or deep learning algorithms to conduct a comprehensive analysis of multi-dimensional environmental data to assess potential fire risks. The algorithm will consider historical data, environmental change trends, weather factors and other factors to perform complex pattern recognition and risk assessment.

[0128] On this basis, the system will also use predictive models to predict fire risks in the future. The predictive model will combine current data and historical data to analyze the development trend of fire risks and provide strong support for decision-making.

[0129] 3. Early warning information release:

[0130] When the risk assessment results reach the preset threshold or the model predicts that a fire risk is about to occur, the early warning system will issue early warning information to relevant personnel through a variety of methods, including but not limited to APP push, SMS notification, email reminder, etc. The early warning information usually includes the specific location, level, and recommended response measures of the fire risk, so that relevant personnel can take timely action.

[0131] (II) Collaborative workflow of the alarm system

[0132] 1. Receive warning signals and make judgments:

[0133] After the alarm system receives the warning signal sent by the early warning system, it will first verify and judge the signal. This step is mainly to ensure the accuracy and reliability of the warning signal and prevent false alarms or malicious alarms. The verification process may include verifying the signal source, checking data consistency, etc.

[0134] If the early warning signal is confirmed to be valid, the alarm system will determine whether it is necessary to trigger the alarm mechanism based on the preset alarm conditions and logic. These conditions may include the fire risk assessment level, risk duration, changes in environmental factors, etc.

[0135] 2. Alarm triggering and information release:

[0136] Once the alarm triggering conditions are met, the alarm system will quickly activate the alarm mechanism. At this time, the alarm information release module will release the fire alarm information to relevant personnel through multiple channels, including but not limited to sound and light alarms (emitting high-decibel sirens and flashing lights at the charging station), voice broadcasts (playing preset fire alarm voice messages), APP push (sending detailed alarm information to the user's mobile phone), SMS notifications (sending fire alarm SMS messages to users) and emergency phone calls (automatically dialing the preset emergency contact number).

[0137] The content of the alarm information usually includes key information such as the specific location, time, risk level, recommended evacuation routes and self-rescue measures of the fire, so that relevant personnel can quickly understand the fire situation and make correct responses.

[0138] 3. Linkage control and initial fire extinguishing:

[0139] When the alarm is triggered, the alarm system will automatically start or control the fire-fighting facilities in the charging station through the linkage control unit for initial fire extinguishing. The linkage control unit will establish a communication interface with the fire-fighting facilities, receive and execute control instructions, and according to the fire situation and control strategy, the system will give priority to starting fire-fighting facilities such as automatic sprinkler fire extinguishing systems, gas fire extinguishing systems or smoke exhaust systems for preliminary control.

[0140] During the initial firefighting process, the system will monitor the development of the fire in real time and adjust the control strategy as needed. If the fire is controlled or weakened, the system will continue to monitor; if the fire intensifies or spreads to other areas, the system will immediately notify relevant personnel and take further response measures.
