Description

[0002] In the field of fire safety management of cultural relic buildings, it is crucial to give timely and accurate early warnings of fire risks. Existing early warnings for the fire safety of cultural relic buildings mostly rely on single-type sensor data or simple threshold judgments. For example, early warnings are made only based on smoke concentration or temperature data. However, the internal environment of cultural relic buildings is complex, and single data is difficult to comprehensively reflect the real fire risk situation. When there are environmental interferences causing abnormal fluctuations in sensor data, or when multiple fire-related factors exist simultaneously but do not reach the triggering conditions of a single threshold, traditional early warning methods may produce false alarms or missed alarms, and cannot achieve accurate judgment and classification early warning of the fire safety risks of cultural relic buildings, affecting the timeliness and effectiveness of subsequent emergency handling.

In addition, corresponding early warning signals are sent according to the grading results, so that the management personnel can quickly and intuitively understand the fire risk level, so as to take targeted emergency measures, improve the accuracy and effectiveness of the fire safety early warning of cultural relic buildings, and more effectively ensure the safety of cultural relic buildings. Description of the Drawings

[0048] Figure 1 is the flow chart of the present invention. Detailed Embodiments

[0049] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0050] Refer to Figure 1 As shown, the method for grading and early warning of fire safety of cultural relic buildings based on event driving includes the following steps:

[0051] Obtain the monitoring data in the cultural relic building, and the monitoring data includes fire-related parameter data;

[0052] Based on the event driving mechanism, judge whether to trigger an early warning event according to the preset event trigger conditions.

[0053] If a warning event is triggered, the monitoring data is analyzed and processed;

[0054] Based on the analysis and processing results, the fire safety of cultural relics buildings is graded according to the preset classification rules;

[0055] According to the classification results, warning signals of corresponding levels are issued.

[0056] Specifically, this method adopts an event-driven mechanism, which changes the traditional passive monitoring mode. By actively acquiring fire-related parameter data, the subsequent analysis and processing process is started only when the preset trigger conditions are met, thus avoiding invalid data processing and saving computing resources. In practical applications, the system only starts in-depth analysis when an event with a possible fire risk is detected, reducing unnecessary resource consumption. Through the analysis and processing of monitoring data and graded warning, different levels of warning signals can be issued in a targeted manner according to the actual situation of fire risks. Compared with the traditional single-mode warning, the accuracy and effectiveness of the warning are improved, so that managers can respond quickly according to the warning level, take appropriate emergency measures, and more effectively protect the safety of cultural relics buildings.

[0057] The fire-related parameter data includes at least one of smoke concentration data, temperature data, open flame detection data, and combustible gas concentration data;

[0058] The obtaining of monitoring data in the cultural relic building specifically includes: collecting fire-related parameter data in real time through sensors arranged in the cultural relic building, and transmitting the collected data to a data processing module.

[0059] Specifically, various types of sensors are used to collect fire-related data of different dimensions to capture signs of fire from multiple angles. Because when a fire occurs, parameters such as smoke, temperature, open flames, and combustible gas concentrations often change. Multiple data complement and verify each other, and can more comprehensively and accurately reflect the fire risk situation. Compared with relying solely on a single data, the possibility of false alarms and missed alarms is greatly reduced. For example, when the smoke concentration in the environment rises briefly due to non-fire factors, combined with other data such as temperature, it can avoid misjudgment as a fire. At the same time, real-time data collection and transmission ensures the timeliness of the data, providing a reliable basis for subsequent rapid judgment and handling of fire risks.

[0060] The preset event triggering conditions include: at least one of the smoke concentration exceeding a first preset threshold, the temperature exceeding a second preset threshold, an open flame being detected, and the combustible gas concentration exceeding a third preset threshold;

[0061] Based on the event-driven mechanism, determining whether to trigger a warning event according to the preset event triggering conditions specifically includes: comparing the collected fire-related parameter data with the corresponding preset thresholds. If the preset event triggering conditions are met, it is determined that a warning event is triggered.

[0062] Specifically, setting clear preset thresholds as event triggering conditions and comparing the collected data with them can quickly determine whether there is a fire risk. This quantitative judgment method enables the system to automatically identify potential fire risks without the need for manual real-time monitoring and judgment, improving the timeliness of early warning. Moreover, the setting of multiple triggering conditions covers the main characteristic manifestations during a fire. No matter what stage the fire is in, there are corresponding triggering conditions for monitoring, further improving the reliability and comprehensiveness of the early warning system.

[0063] The analysis and processing of the monitoring data specifically include:

[0064] Performing filtering processing on the collected smoke concentration data to remove noise data;

[0065] Performing trend analysis on the temperature data to obtain the temperature change rate;

[0066] Performing feature extraction on the open fire detection data to determine the location and scope of the open fire;

[0067] Performing concentration gradient analysis on the combustible gas concentration data.

[0068] Specifically, adopting targeted analysis and processing methods for different types of data improves the usability and accuracy of the data. Filtering processing can remove noise interference in the smoke concentration data, making the data more accurately reflect the actual smoke situation; performing trend analysis on the temperature data not only focuses on the current temperature but also considers the temperature change trend, enabling earlier detection of fire hazards because the temperature usually shows a specific upward trend during a fire; performing feature extraction on the open fire detection data helps accurately determine the location and scope of the open fire, providing key information for subsequent fire fighting and rescue; performing concentration gradient analysis on the combustible gas concentration data can understand the diffusion situation of combustible gases and judge the possibility and scope of fire spread. Through these analyses and processing, more accurate and reliable data support is provided for subsequent fire safety grading, thereby improving the accuracy and effectiveness of the entire early warning system.

[0069] The classification of the fire safety of cultural relics buildings according to the preset classification rules specifically includes:

[0070] Establishing a classification evaluation model, the formula is:

[0071]

[0072] Among them, is the comprehensive fire safety score, is the smoke concentration score, is the temperature score, is the open fire score, is the combustible gas concentration score, , , , are the weight coefficients corresponding to the respective parameters;

[0073] According to the comprehensive fire safety score , fire safety grading is carried out according to a preset score range.

[0074] Specifically, by establishing a grading evaluation model, comprehensively considering the scores of various fire-related parameters, and combining their respective weight coefficients to calculate the comprehensive fire safety score, it is possible to comprehensively and objectively evaluate the fire safety status of cultural relic buildings. Different fire-related parameters have different importance in the occurrence and development of a fire. Setting weight coefficients can highlight the influence of key factors. Compared with simply making a judgment based on a single piece of data or a small amount of data, this comprehensive evaluation method can more accurately reflect the true degree of fire risk. Grading according to the preset score range divides the fire risk into different levels, enabling managers to clearly understand the current fire risk level faced by cultural relic buildings, so that corresponding prevention and emergency measures can be taken according to different levels, realizing the refined management of fire risk and improving the efficiency and effect of fire safety management of cultural relic buildings.

[0075] The specific preset score range is as follows:

[0076] When the comprehensive fire safety score meets , the fire safety grading is level one;

[0077] When , the fire safety grading is level two;

[0078] When , the fire safety grading is level three;

[0079] Among them, the boundary values of each score range include the lower limit value and do not include the upper limit value.

[0080] Specifically, clearly define the specific grading intervals to make the fire safety grading have clear criteria and operability. This quantitative grading method enables managers to intuitively judge the fire safety level of current cultural relic buildings, avoiding the ambiguity and subjectivity of grading. Different grades correspond to different degrees of fire risks, and managers can quickly formulate and implement corresponding countermeasures according to the grading results. For example, for first-level risks, strengthen daily inspections and monitoring; for third-level risks, immediately take measures such as emergency evacuation and fire extinguishing preparations, improving the pertinence and effectiveness of emergency responses and further ensuring the safety of cultural relic buildings.

[0081] The sending of corresponding-level warning signals according to the grading results specifically includes:

[0082] If the fire safety grading is first level, a low-frequency and low-intensity warning signal is sent through an audible and visual alarm;

[0083] If the fire safety grading is second level, a medium-frequency and medium-intensity warning signal is sent through an audible and visual alarm;

[0084] If the fire safety grading is third level, a high-frequency and high-intensity warning signal is sent through an audible and visual alarm.

[0085] Specifically, sending audible and visual warning signals with different intensities and frequencies according to different fire safety gradings realizes the differentiation of warning signals. In this way, managers and relevant personnel can quickly identify the level of current fire risks through the characteristics of the warning signals without checking detailed data and grading information. Low-frequency and low-intensity signals indicate lower risks, reminding relevant personnel to pay attention and take appropriate preventive measures; high-frequency and high-intensity signals indicate higher risks, warning relevant personnel to immediately take emergency response actions. Through the setting of this graded warning signal, the efficiency and accuracy of information transmission are improved, ensuring that relevant personnel can quickly make correct responses in different fire risk situations and effectively enhancing the effect of fire safety warning for cultural relic buildings.

[0086] An event-driven fire safety grading warning system for cultural relic buildings includes:

[0087] A data acquisition module for obtaining monitoring data in the cultural relic building, where the monitoring data includes fire-related parameter data;

[0088] An event judgment module, based on an event-driven mechanism, for judging whether to trigger a warning event according to preset event trigger conditions;

[0089] A data analysis module for analyzing and processing the monitoring data if a warning event is triggered;

[0090] A grading module, which is used to grade the fire safety of cultural relic buildings according to the analysis and processing results in accordance with the preset grading rules;

[0091] An early warning module, which is used to send out early warning signals of corresponding levels according to the grading results.

[0092] Specifically, the functions of each module of the system are clearly defined and cooperate with each other, and the fire safety grading and early warning function of cultural relic buildings based on event-driven are fully realized. The data acquisition module ensures the acquisition of comprehensive and timely monitoring data; the event judgment module quickly judges whether an early warning event is triggered according to the preset conditions and starts the subsequent process; the data analysis module deeply processes the data to improve the data quality; the grading module accurately grades the fire safety based on the processed data; the early warning module sends out corresponding early warning signals according to the grading results. Each module cooperates closely to form an organic whole. Compared with the traditional decentralized early warning system or single-function equipment, the integration degree and collaborative working ability of the system are improved, the efficient operation of the early warning system is ensured, and the fire safety of cultural relic buildings can be more reliably guaranteed.

[0093] The data acquisition module is connected to the event judgment module through a wired transmission line, and transmits the collected monitoring data to the event judgment module in real time;

[0094] A wireless communication method is used to connect the event judgment module and the data analysis module. When the event judgment module determines that an early warning event is triggered, it sends the relevant data to the data analysis module through the wireless network;

[0095] The data analysis module is connected to the grading module through a data bus, and transmits the analysis and processing results to the grading module;

[0096] A serial communication interface is used to connect the grading module and the early warning module. The grading module sends the grading results to the early warning module to trigger corresponding early warnings.

[0097] Specifically, a variety of different connection methods are adopted, and reasonable configuration is carried out according to the characteristics and requirements of data transmission between each module, optimizing the data transmission process inside the system, improving the efficiency and reliability of data transmission, and ensuring the stable operation of the entire early warning system.

[0098] A data buffer queue is set between the event judgment module and the data analysis module, which is used to temporarily store the monitoring data after the early warning event is triggered to ensure the continuity of data processing;

[0099] The early warning module includes a multi-channel early warning unit. The multi-channel early warning unit is respectively connected to an audible and visual alarm device, a short message sending device and a network communication device, and can select the corresponding early warning channel combination to send out early warning signals according to different early warning levels.

[0100] Specifically, a data buffer queue is set between the event judgment module and the data analysis module, which can temporarily store the monitoring data after a warning event is triggered. This is because during the data processing, there may be a situation where the data processing speed does not match the data transmission speed. The data buffer queue can prevent data loss or chaos, ensure the continuity and integrity of data processing, and thus improve the stability of the system. The multi-channel warning unit of the warning module connects various warning devices and selects different warning channel combinations according to different warning levels. For example, for a lower-level warning, only the on-site personnel can be reminded through the acoustic and optical alarm devices; for a higher-level warning, relevant management personnel are notified through the SMS sending device at the same time, and the warning information is released through the network communication device to expand the warning range. This multi-channel warning method can achieve accurate and effective warning information transmission according to the actual needs and risk levels, improve the adaptability and practicability of the warning system, and ensure that relevant personnel can be notified in a timely manner in various situations so as to take corresponding measures to deal with the fire risk.
