Description

Technical Field

[0001] This invention relates to the field of electric vehicle charging safety protection technology, specifically to a multi-scenario intelligent alarm fire extinguishing remote control electric vehicle charging station. Background Technology

[0003] With the widespread use of electric bicycles, electric motorcycles, and other personal transportation vehicles, the demand for centralized charging in both public and private settings continues to grow. Existing conventional electric vehicle charging stations have limited structural functionality and generally suffer from shortcomings in fire safety protection, making them prone to fire accidents.

[0004] Currently, traditional charging stations only have basic power on / off and simple overcurrent protection functions. Their safety monitoring methods are limited, relying mainly on single temperature or current sensors for anomaly detection. This results in weak resistance to environmental interference and susceptibility to problems such as missed fire alarms and false alarms triggered by environmental factors. Furthermore, existing equipment lacks a tiered fire-fighting response structure, making it impossible to match appropriate response measures based on the severity of the hazard. The thermal runaway of electric vehicle power batteries is characterized by its suddenness, persistence, and susceptibility to reignition. Single fire extinguishing methods are insufficient for long-term fire control, and residual battery heat can easily trigger secondary reignition, posing significant safety hazards.

[0005] Furthermore, existing charging stations have low levels of intelligence, often only equipped with simple local alarms. Managers cannot remotely obtain real-time information on equipment operation, charging anomalies, and fires, relying heavily on manual on-site inspections. In unattended scenarios, fire response is delayed, easily leading to fire spread and property damage. Moreover, traditional equipment has a fixed structure and poor adaptability, making it difficult to integrate with various installation environments such as underground parking lots, residential areas, outdoor streets, industrial parks, and commercial garages, limiting its general usability.

[0006] In summary, existing electric vehicle charging stations suffer from several technical deficiencies, including limited monitoring dimensions, frequent false alarms and missed alarms, insufficient fire protection capabilities, lack of reignition prevention, lack of remote management and control, and poor adaptability to different scenarios. Summary of the Invention

[0008] Purpose of the invention This invention addresses the shortcomings of existing technologies, such as incomplete monitoring methods, delayed fire response, susceptibility to battery reignition, lack of intelligent control, and limited applicability. It provides a remotely controlled electric vehicle charging station with multi-scenario intelligent alarm and fire suppression capabilities. By combining hardware architecture with hierarchical linkage control logic, this invention achieves multi-source collaborative monitoring, hierarchical fire response, closed-loop reignition prevention and control, and remote centralized management, effectively improving charging operation safety and adaptability to multiple scenarios. Technical solution

[0010] To achieve the above objectives, the present invention adopts the following technical solution: A multi-scenario intelligent alarm and fire extinguishing remote control electric vehicle charging station includes a main charging structure, a multi-source sensing module, a central control unit, a graded fire extinguishing actuator, a remote communication module, and a power supply management module; the multi-source sensing module, the graded fire extinguishing actuator, the remote communication module, and the power supply management module are electrically connected to the central control unit.

[0011] The multi-source sensing module is used to collect images of temperature, smoke, and flames around the charging station, as well as charging current and voltage operation signals in real time, and transmits the collected data to the central control unit in real time. The central control unit has a built-in multi-condition cross-fusion judgment logic to perform linkage verification on multi-source monitoring signals, reduce the judgment error caused by environmental interference of single sensor data, and classify and identify different risk states such as equipment abnormality, battery overheating, initial fire, and severe thermal runaway. When an abnormality or fire hazard is identified, the power supply management module is linked to cut off the charging power supply, and according to the level of danger, the graded fire extinguishing actuators are controlled to perform corresponding protection and fire extinguishing actions.

[0012] The remote communication module enables two-way data interaction with the remote management platform, uploading equipment operating status, alarm information, and fire extinguishing execution records in real time. It also receives remote control commands from the platform to complete remote monitoring and remote operation management of the equipment.

[0013] Furthermore, the multi-condition cross-fusion judgment logic is a hardware-adaptive operating rule that relies on multiple sets of on-site monitoring data for collaborative judgment: simultaneously collecting multiple sets of parameters such as ambient temperature, smoke concentration, flame image features, and charging current and voltage, and setting graded thresholds; when a single monitoring parameter is abnormal, it is judged as an equipment warning state; when two or more sets of parameters are simultaneously abnormal, it is judged as an initial fire; when three or more sets of parameters are simultaneously abnormal, it is judged as a severe thermal runaway hazard. Different risk levels correspond to different handling procedures, effectively avoiding misjudgment problems caused by environmental factors.

[0014] Furthermore, the multi-source sensing module includes a temperature detection component, a smoke detection component, a flame visual recognition component, a current acquisition unit, and a voltage acquisition unit, simultaneously covering environmental fire monitoring and electrical operation fault monitoring.

[0015] Furthermore, the graded fire extinguishing mechanism includes an early warning ventilation unit, an aerosol fire extinguishing unit, and a fine water mist or dry powder fire extinguishing unit, which respectively correspond to the three levels of response needs: early warning protection, initial fire, and severe fire. The graded mechanisms are independently triggered and linked, taking into account both response efficiency and protection rationality.

[0016] Furthermore, the main charging structure integrates fireproof partitions, flame-retardant protection, and ventilation and heat dissipation structures, which can prevent the spread of open flames and is suitable for various installation and use scenarios such as indoor enclosed spaces and outdoor open venues.

[0017] Furthermore, this device is also equipped with a local audible and visual alarm unit, which is connected to the central control unit and simultaneously issues a local warning signal when an anomaly or fire is detected.

[0018] Furthermore, the remote communication module adopts wireless communication transmission to adapt to different site network deployment conditions; the central control unit integrates a data storage unit to uniformly store sensor monitoring data, charging operation records, alarm logs and fire extinguishing operation records, meeting the needs of safety traceability and equipment operation and maintenance query.

[0019] This invention also provides an intelligent control method adapted to the above-mentioned charging stations, which relies on the equipment hardware carrier to realize fully automatic closed-loop management and control, and fully covers the entire process of real-time data acquisition, intelligent hierarchical judgment, hierarchical emergency response, continuous monitoring of reignition, and remote data synchronization.

[0020] Beneficial effects

[0021] Compared with existing conventional technologies, the present invention has the following technical advantages: 1. Multi-source collaborative monitoring ensures accurate and reliable judgment. Employing a multi-parameter cross-validation judgment mode overcomes the susceptibility of single sensors to environmental interference, reducing the probability of false alarms and missed fire detections, and improving the accuracy of risk identification.

[0022] 2. Tiered fire suppression and coordination to prevent reignition risk. A multi-tiered response structure is adopted to match the needs of different fire levels. Combined with continuous monitoring after fire suppression, a closed-loop protection is formed to suppress reignition caused by residual heat from the battery.

[0023] 3. Remote intelligent management and control, adaptable to unattended operation. Supports remote status viewing, anomaly alarms, and remote command control, reducing reliance on manual on-site inspections, lowering daily operation and maintenance costs, and improving emergency response speed.

[0024] 4. Modular protective structure, suitable for multiple scenarios. The overall structure has flame-retardant, heat-insulating, fireproof, and ventilation and heat dissipation properties, and can be widely adapted to various charging scenarios such as underground garages, residential areas, industrial parks, commercial areas, and outdoor public spaces.

[0025] 5. Operational data retention ensures compliance and traceability. All operational, alarm, and fire suppression data are stored and archived uniformly, facilitating subsequent equipment maintenance, safety inspections, and compliance traceability management. Attached Figure Description

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0031] The multi-scenario intelligent alarm fire extinguishing remote control electric vehicle charging station disclosed in this invention consists of a physical hardware structure and a linkage control system. All control logic and judgment rules rely on hardware devices to achieve stable operation.

[0032] The main charging structure serves as the foundation for the overall equipment. It adopts a flame-retardant protective shell and has an independent fireproof compartment inside. The charging interface, electronic control module, and fire-fighting components are arranged in separate zones. At the same time, a through-type heat dissipation channel is set up to effectively dissipate the heat accumulated during equipment operation, avoid high temperature accumulation in the confined space, and suppress the lateral spread of open flame through physical barrier structure. It is suitable for complex usage environments such as enclosed garages, outdoor exposure, and limited ventilation.

[0033] The multi-source sensing module collects on-site environmental and equipment operating parameters in real time around the clock, including key information such as ambient temperature, smoke concentration, flame shape characteristics, charging circuit current, and operating voltage, and continuously uploads the real-time monitoring signals to the central control unit.

[0034] After receiving all monitoring data, the central control unit completes the status classification judgment through the built-in multi-condition cross-fusion judgment logic: when a single sensor parameter shows a slight abnormality, it is judged as an equipment warning, and the local audible and visual alarm is immediately activated, and the warning information is pushed to the remote management platform to prompt the operation and maintenance personnel to check for potential hazards in advance; when both temperature and smoke parameters exceed the threshold simultaneously, it is judged as an initial thermal runaway of the battery, and the power supply of the charging circuit is immediately cut off, and the ventilation unit and aerosol fire extinguishing unit are activated simultaneously to quickly suppress the spread of the initial fire; when multiple sets of parameters such as temperature, smoke, and flame detection simultaneously trigger the warning conditions, it is judged as a severe thermal runaway accident, and the advanced fire extinguishing unit is automatically activated to implement full-area fire control.

[0035] After the fire is extinguished, the central control unit maintains continuous monitoring, continuously collects on-site environmental parameters, and captures in real time warning signals of reignition such as temperature rise and residual smoke. If necessary, it will trigger secondary protection and fire extinguishing actions to build a long-term closed-loop prevention and control system.

[0036] The entire process of equipment operation data is automatically stored in the built-in data storage unit, including charging records, sensor monitoring data, alarm records, and fire-fighting execution records, facilitating later retrieval and verification. The remote management platform can issue control commands via wireless communication links to realize remote management functions such as remote start / stop of equipment, parameter configuration, forced power-off, and status inspection.

[0037] The invention has a stable overall structure, rigorous control logic, and high degree of software and hardware synergy. It can meet the fire safety management and control needs of centralized charging in multiple scenarios, and has strong practicality and adaptability, making it suitable for widespread application.
