Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0082] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0083] Example 1, reference Figure 1 , which is the first embodiment of the present invention, provides a GDS alarm centralized control system, including the following steps:

[0084] Data acquisition module, priority processing module, alarm generation module, control module, data management module and optimization module;

[0085] The data acquisition module is used to collect gas concentrations in the environment using a variety of sensors to obtain original monitoring data;

[0086] Furthermore, the gas sensor MICS-6814 based on electrochemical principle was selected;

[0087] Install a corresponding electrochemical gas sensor at each predetermined location. Each sensor is connected to an A / D converter via a cable to convert the analog signal into a digital signal, and use OPC UA as a protocol conversion gateway.

[0088] After receiving the digital signal from the sensor, the central processing unit calculates the actual gas concentration and obtains the original monitoring data, which is expressed as:

[0089]

[0090] Where C is the actual concentration of the target gas, V s is the currently measured voltage value, V0 is the baseline voltage in the absence of target gas, S is the sensitivity coefficient, which is a fixed parameter of the sensor, and C0 is a predetermined calibration value;

[0091] It should be noted that the electrochemical-based gas sensor MICS-6814 was selected not only for its high sensitivity and good linear response characteristics, but also for its excellent stability and long service life in industrial environments. The use of OPC UA as a protocol conversion gateway ensures seamless communication between devices of different brands and improves the compatibility and scalability of the system.

[0092] Priority processing module, used to pre-process the original monitoring data and dynamically adjust the alarm priority according to the preset safety threshold to obtain filtered and graded data information;

[0093] Furthermore, all received gas concentration data are preliminarily processed to remove obvious outliers;

[0094] Set the corresponding safety threshold according to different gas types. The expression is:

[0095]

[0096] Among them, P is the alarm priority, C is the actual concentration of the target gas, T low , T mid , T high There are three safety thresholds: low, medium and high;

[0097] Combine the gas concentration data processed by the above steps and its corresponding alarm priority P to form new data information;

[0098] Each record contains two key fields, namely the gas concentration and the corresponding alarm priority;

[0099] It should be noted that when pre-processing the original monitoring data, removing outliers can not only reduce the system's false alarm rate, but also improve the accuracy of alarm decisions. By setting different security thresholds and dynamically adjusting alarm priorities, the system can more accurately identify potential risks and take corresponding measures based on the actual threat level, thereby improving the overall safety management level.

[0100] The intelligent alarm generation module is used to analyze and judge the filtered and classified data information using alarm logic. When the conditions are met, the corresponding alarm signal is generated and notifications are sent to relevant personnel according to the priority mechanism to obtain the alarm signal and notification information;

[0101] Furthermore, according to different alarm priorities, specific alarm trigger conditions are set, and alarm levels are introduced to determine whether to alarm. The expression is:

[0102]

[0103] Among them, A is the alarm level, ranging from 0 to 3, with a larger value indicating a higher degree of urgency; P is the alarm priority, ranging from 1 to 4, with a larger value indicating a higher degree of urgency;

[0104] When A>0, the corresponding alarm signal is triggered;

[0105] For each data record, if its corresponding alarm level A is greater than 0, a corresponding alarm signal is generated;

[0106] Alarm signals include gas type, actual gas concentration, alarm priority and alarm level;

[0107] According to the alarm level A, select different notification methods to send notifications to relevant personnel;

[0108] When A=1, the relevant operators are notified via internal system messages or low-priority emails;

[0109] When A=2, the relevant operators will be notified via SMS or instant messaging tools, and a highlighted warning will be displayed on the system interface;

[0110] When A=3, all relevant operators will be notified immediately through multiple channels such as phone calls, text messages, instant messaging tools, etc., and a red emergency warning will be displayed on the system interface;

[0111] Define the function N(A) to select the notification method. The expression is:

[0112]

[0113] Where N(A) is the notification method selected according to the alarm level, and A is the alarm level;

[0114] Send notifications to relevant personnel based on the selected notification method N(A);

[0115] It should be noted that the introduction of the alarm level mechanism can not only refine the urgency of the alarm information, but also select appropriate notification methods according to different levels of alarms to ensure that key information can be quickly conveyed to relevant personnel. The multi-level notification mechanism effectively avoids the problem of information overload and improves the speed and efficiency of emergency response.

[0116] The control module is used to analyze alarm signals and notification information using a scenario-based rule engine, activate related devices according to preset linkage strategies, and obtain feedback on device status after execution;

[0117] Furthermore, scenario-based rules can be defined based on different gas types and alarm levels;

[0118] Each scenario rule corresponds to a specific set of operations;

[0119] Define the function to select the corresponding operation, the expression is:

[0120]

[0121] Where R(G,A) is the operation selected based on the gas type G and the alarm level A, G is the gas type, and A is the alarm level;

[0122] Parse each received alarm signal, extract key information, and then select the corresponding action based on the scenario-based rule engine defined above;

[0123] When the detected gas is CO and the alarm level A≥2, select the "Close Valve" operation;

[0124] When the detected gas is NO2 and the alarm level A≥2, select the "Start ventilation system" operation;

[0125] When the alarm level reaches the highest level A=3, select the "Emergency Stop" operation;

[0126] According to the selected operation, send instructions to relevant equipment through the central control system;

[0127] For the "close valve" operation, the system will send a command to the electric valve controller to close the specified valve;

[0128] For the "start ventilation system" operation, the system will send a command to the ventilation system controller to start the corresponding fan;

[0129] After executing the operation of the relevant equipment, obtain the equipment status feedback S from the equipment controller;

[0130] It should be noted that the design of the scenario-based rule engine enables the system to automatically select the optimal operation strategy according to different gas types and alarm levels, realizing intelligent emergency response. Different response measures are taken for different gases such as CO and NO2, which can minimize accident risks and ensure the safety of personnel and facilities.

[0131] The data management module is used to integrate data from multiple sources and store them in a database for unified management and display;

[0132] Furthermore, the integration of multi-source data includes raw monitoring data, filtered and graded data information, alarm signals and notification information, and equipment status feedback after execution;

[0133] Standardize all data received to ensure that each type of data follows a consistent format;

[0134] Integrate data from different sources according to timestamps and establish associations between data. The expression is:

[0135] D={T std ,G,C,P,A,N(A),R(G,A),S};

[0136] Among them, D is the integrated data record, T std is the normalized timestamp, G is the gas type, C is the actual gas concentration, P is the alarm priority, A is the alarm level, N(A) is the notification method selected based on the alarm level, R(G,A) is the operation selected based on the gas type and alarm level, and S is the device operation status;

[0137] Storing the integrated data record D in the central database;

[0138] It should be noted that standardizing and integrating data from multiple sources not only ensures the consistency and comparability of the data, but also provides a solid foundation for subsequent data analysis and optimization. By establishing correlations between data, the system can comprehensively and accurately record the development process of each event, facilitating subsequent tracing and analysis.

[0139] The optimization module is used to analyze the data managed and displayed regularly, evaluate the accuracy of alarms and the efficiency of responses, and optimize the alarm logic, priority settings, and linkage strategies based on the evaluation results to obtain the optimized alarm logic, priority settings, and linkage strategies;

[0140] Furthermore, all received data records are batch processed to calculate the alarm accuracy and average response time in each time period;

[0141] Define the function summary statistics, the expression is:

[0142]

[0143] Where Stats(D) is the statistical result set, and n is the number of data records in the statistical time period;

[0144] Identify problems in the system based on the calculated alarm accuracy Acc and average response time RT;

[0145] Based on the above analysis results, adjust the safety threshold in the alarm logic;

[0147] Optimize the linkage strategy in the scenario-based rule engine based on device operation status feedback;

[0149] It should be noted that regular analysis and evaluation of system data, and optimization of alarm logic, priority settings, and linkage strategies based on the evaluation results, are key steps in achieving system self-improvement and continuous optimization. The closed-loop feedback mechanism can not only promptly discover and resolve problems in the system, but also continuously improve the performance and reliability of the system, ensuring that it is always in the best operating state.
