[0001] This invention relates to the field of alarm signal processing technology, and in particular to a method for processing alarm signals from a gas alarm detector. Background Technology

[0002] A gas alarm detector is a device used to detect the concentration of a specific gas. Once the detected gas concentration exceeds a preset threshold, it will issue an alarm signal. This type of device is widely used in industrial safety, home security, and environmental monitoring to ensure personnel safety and environmental protection. In traditional gas alarm detector alarm signal processing methods, the gas concentration in the air is typically detected and compared with a preset alarm threshold; if it exceeds the threshold, an alarm is triggered.

[0003] However, traditional gas alarm detector alarm signal processing methods have some limitations and shortcomings: false alarms may occur due to environmental factors or sensor performance, leading to unnecessary panic and waste of resources; data processing is usually relatively simple and cannot be adapted to changes in the environment. Therefore, there is an urgent need for a gas alarm detector alarm signal processing method that can adapt to alarm methods in complex environments. Summary of the Invention

[0006] In some embodiments of this application, determining the installation scenario of the gas alarm detector based on the address code includes: A gas alarm detector installation table is pre-set, which includes the address code of the gas alarm detector and the address code corresponds to the installation scenario of the gas alarm detector. The address code of the gas alarm detector is determined based on the gas concentration signal; Based on the gas alarm detector installation table, the installation scenario of the gas alarm detector is determined according to the address code.

[0007] In some embodiments of this application, environmental data of the gas alarm detector installation scenario is obtained, including: Based on the installation scenario of the gas alarm detector, select the environmental detector corresponding to the installation scenario, and obtain the environmental data of the installation scenario based on the environmental detector; The environmental data includes temperature, humidity, air pressure, and air circulation.

[0009] In some embodiments of this application, the gas concentration alarm threshold is calculated according to the following formula:

[0010] in, Indicates the gas concentration alarm threshold. Indicates the initial gas concentration threshold. This represents the first influence coefficient. This represents the second influence coefficient. The third influence coefficient is represented by T, where T represents temperature, W represents humidity, P represents air pressure, and F represents air circulation rate.

[0011] In some embodiments of this application, the alarm signal includes: gas concentration value, gas leak level, and gas leak location.

[0012] In some embodiments of this application, generating an alarm signal based on the gas concentration value and the gas concentration alarm threshold includes: The gas concentration value is compared with the gas concentration alarm threshold. If the gas concentration is not higher than the gas concentration alarm threshold, no alarm signal is generated. If the gas concentration value is higher than the gas concentration alarm threshold, then the gas concentration difference between the gas concentration value and the gas concentration alarm threshold is determined, the gas leakage level is determined based on the gas concentration difference, and an alarm signal is generated based on the gas concentration signal and the gas leakage level.

[0013] In some embodiments of this application, determining the gas leakage level based on the gas concentration difference includes: A first gas concentration difference, a second gas concentration difference, and a third gas concentration difference are preset, and the first gas concentration difference, the second gas concentration difference, and the third gas concentration difference increase sequentially; The gas leakage level is set according to the relationship between the gas concentration difference and the first gas concentration difference, the second gas concentration difference, and the third gas concentration difference; If the gas concentration difference is less than the first gas concentration difference, then the gas leakage level is set to the first gas leakage level L1; If the gas concentration difference is greater than or equal to the first gas concentration difference, and the gas concentration difference is less than the second gas concentration difference, then the gas leakage level is set to the second gas leakage level L2. If the gas concentration difference is greater than or equal to the second gas concentration difference, and the gas concentration difference is less than the third gas concentration difference, then the gas leakage level is set to the third gas leakage level L3.

Obviously, the drawings described below are only embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on the provided drawings without creative effort.

[0017] Figure 1 This is a flowchart illustrating the alarm signal processing method for a gas alarm detector according to the present invention. Detailed Implementation

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0019] like Figure 1 As shown, the present invention provides a method for processing alarm signals of a gas alarm detector, the method comprising: S1. The gas alarm detector is address-encoded to form an address code, which is unique and non-repeating.

[0020] S2 receives a gas concentration signal from a gas alarm detector, the gas concentration signal including a gas concentration value and an address code.

[0021] S3, determine the installation scenario of the gas alarm detector based on the address code.

[0022] S4. Obtain environmental data of the gas alarm detector installation scene, and set the gas concentration alarm threshold based on the environmental data.

[0023] S5, generate an alarm signal based on the gas concentration value and the gas concentration alarm threshold, and perform an audible and visual alarm.

[0024] In some embodiments of this application, an address encoder is used to encode the gas alarm detector, and the address code is unique and non-repeating.

[0025] In this embodiment, to ensure accurate positioning and efficient management of the gas alarm detectors, an advanced address encoder is used to provide detailed address encoding for these detectors. Each address code is carefully designed to ensure its uniqueness and non-repeatability. This means that among numerous detectors, no single detector's address code will be the same as any other detector, thus avoiding address code confusion and misuse. This unique address encoding method not only improves the reliability of the gas alarm system but also greatly facilitates subsequent maintenance and management.

[0026] In some embodiments of this application, determining the installation scenario of a gas alarm detector based on the address code includes: having a preset gas alarm detector installation table, the gas alarm detector installation table including the address codes of gas alarm detectors, the address codes corresponding to the installation scenarios of the gas alarm detectors; determining the address code of the gas alarm detector based on the gas concentration signal; and determining the installation scenario of the gas alarm detector based on the gas alarm detector installation table and the address code.

[0027] In this embodiment, a gas alarm detector installation table is pre-set, which records the address codes of the gas alarm detectors. Each address code corresponds to an installation scenario for the gas alarm detector, including the installation location and environment. The installation scenario of the gas alarm detector is determined based on the address code of the received gas concentration signal.

[0028] Understandably, the first step is to create a detailed gas alarm detector installation schedule. This schedule will record the unique address code of each gas alarm detector, accurately pinpointing its exact location. This address code records not only the detector's physical location but also its installation environment. These environments include, but are not limited to, the detector's intended use location and surrounding environment.

[0029] When the detector is operational, it monitors the surrounding gas concentration in real time and transmits this information along with an address code. Upon receiving these signals, the receiver uses the address code to determine which detector emitted the signal, thus accurately assessing the gas concentration in the detector's installation environment. This allows for effective monitoring and management of gas concentrations based on the detector's installation location, ensuring the safety of people and property. It also facilitates the rapid location of affected areas and the implementation of appropriate countermeasures in emergencies such as gas leaks, thereby ensuring personnel safety and minimizing property damage.

[0030] In some embodiments of this application, obtaining environmental data of the gas alarm detector installation scenario includes: selecting an environmental detector corresponding to the installation scenario of the gas alarm detector, and obtaining environmental data of the installation scenario based on the environmental detector; wherein, the environmental data includes temperature value, humidity value, air pressure value, and air circulation rate.

[0031] In this embodiment, an environmental detector is also installed at the installation location of the gas alarm detector. After determining the installation scene of the corresponding gas alarm detector through the address code, environmental data is obtained through the environmental detector of the corresponding installation scene. The environmental data includes temperature, humidity, air pressure, and air circulation rate.

[0032] Understandably, the installation location of a gas alarm detector is also the location of an environmental detector; the two work together to ensure the accuracy of safety monitoring. After determining the address code of a specific gas alarm detector, the installation scenario of that detector can be accurately identified. Subsequently, based on the environmental detector corresponding to that specific scenario, various key data about that environment can be effectively collected. This environmental data is multifaceted, including but not limited to temperature, humidity, air pressure, and air circulation. The collection of this data is crucial for the operation of the gas alarm detector because it comprehensively reflects the specific conditions of the monitored environment, thereby ensuring that the gas alarm detector can respond promptly and accurately in potentially hazardous situations.

[0033] In some embodiments of this application, setting a gas concentration alarm threshold based on the environmental data includes: setting an initial gas concentration threshold corresponding to the gas based on the type of gas detected by the gas alarm detector; setting a gas concentration threshold adjustment amount based on the environmental data; and setting the gas concentration alarm threshold based on the initial gas concentration threshold and the gas concentration threshold adjustment amount.

[0034] In this embodiment, different gases have different concentration thresholds. The corresponding concentration threshold can be set according to the type of gas, and the concentration threshold can be adjusted according to environmental data, namely temperature, humidity, air pressure and air circulation rate, to obtain the gas concentration alarm threshold.

[0035] Understandably, various gases have specific concentration thresholds, which serve as the benchmark for determining whether a gas has reached a dangerous level. First, based on the functions and characteristics of the installed gas alarm detectors, the type of gas being monitored is identified, and an initial gas concentration threshold is set accordingly. This initial threshold is a baseline value used to determine whether the gas concentration exceeds a safe range. Subsequently, combined with real-time collected environmental data, such as temperature, humidity, and air circulation, an adjustment amount for the gas concentration threshold is calculated. This adjustment amount is to address the impact of changes in environmental factors on the gas concentration monitoring results, ensuring the sensitivity and accuracy of the alarm system. Finally, the initial gas concentration threshold and the gas concentration threshold adjustment amount are added to obtain the final gas concentration alarm threshold. This threshold will serve as the basis for the alarm system to determine whether the gas concentration has reached a dangerous level. Once the detected gas concentration exceeds this threshold, an alarm will be immediately triggered, alerting personnel through sound, light, or other means to take necessary measures to ensure personnel safety and environmental stability.

[0036] In some embodiments of this application, the gas concentration alarm threshold is calculated according to the following formula:

[0037] in, Indicates the gas concentration alarm threshold. Indicates the initial gas concentration threshold. This represents the first influence coefficient. This represents the second influence coefficient. The third influence coefficient is represented by T, where T represents temperature, W represents humidity, P represents air pressure, and F represents air circulation rate.

[0038] In some embodiments of this application, the alarm signal includes: gas concentration value, gas leak level, and gas leak location.

[0039] In this embodiment, the alarm signal includes several important parameters: First, the gas concentration value, which is the level of gas concentration in the environment detected by a precision sensor, and is one of the important indicators for assessing the severity of a gas leak. Second, the gas leak level, which can be classified according to relevant national standards or actual conditions to determine the degree of harm that a gas leak may cause, so as to take appropriate emergency measures. Third, the information on the gas leak location is crucial, as it guides emergency personnel to quickly and accurately locate the leak source, thereby taking effective measures to contain the leak and reduce potential losses. The gas leak location is determined based on the installation location of the gas alarm detector that issued the alarm signal.

[0040] In some embodiments of this application, generating an alarm signal based on the gas concentration value and the gas concentration alarm threshold includes: comparing the gas concentration value with the gas concentration alarm threshold; if the gas concentration is not higher than the gas concentration alarm threshold, then no alarm signal is generated; if the gas concentration value is higher than the gas concentration alarm threshold, then determining the gas concentration difference between the gas concentration value and the gas concentration alarm threshold, determining the gas leakage level based on the gas concentration difference, and generating an alarm signal based on the gas concentration signal and the gas leakage level.

[0041] In this embodiment, the detected gas concentration value is compared in detail with a pre-set gas concentration alarm threshold. During this process, if the detected gas concentration value does not exceed this warning standard (i.e., is lower than or equal to the gas concentration alarm threshold), no alarm signal will be triggered, indicating that the current gas concentration is within a safe range and requires no attention. However, if the detected gas concentration value exceeds the set gas concentration alarm threshold, it means that the gas concentration has reached a dangerous level, requiring further action. In this case, the difference between the gas concentration value and the gas concentration alarm threshold is precisely calculated. This difference reflects the severity of the gas leak. Based on this gas concentration difference, the specific level of the gas leak can be determined, providing a basis for subsequent handling. Once the gas leak level is determined, a corresponding alarm signal is generated by combining the real-time monitored gas concentration signal and the leak level. This alarm signal will be promptly notified to relevant personnel in the form of sound, light, or digital signals, enabling them to quickly take necessary measures to address the gas leak and ensure the safety of personnel and property.

[0042] In some embodiments of this application, determining the gas leakage level based on the gas concentration difference includes: pre-setting a first gas concentration difference, a second gas concentration difference, and a third gas concentration difference, wherein the first gas concentration difference, the second gas concentration difference, and the third gas concentration difference increase sequentially; setting the gas leakage level based on the relationship between the gas concentration difference and the first gas concentration difference, the second gas concentration difference, and the third gas concentration difference; if the gas concentration difference is less than the first gas concentration difference, then the gas leakage level is set as a first gas leakage level L1; if the gas concentration difference is greater than or equal to the first gas concentration difference and the gas concentration difference is less than the second gas concentration difference, then the gas leakage level is set as a second gas leakage level L2; if the gas concentration difference is greater than or equal to the second gas concentration difference and the gas concentration difference is less than the third gas concentration difference, then the gas leakage level is set as a third gas leakage level L3; if the gas concentration difference is greater than or equal to the third gas concentration difference, then the gas leakage level is set as a fourth gas leakage level L4; wherein L1 < L2 < L3 < L4.

[0043] In this embodiment, the specific level of gas leakage can be determined based on the gas concentration difference. The larger the gas concentration difference, the more gas is leaking, and the higher the corresponding gas leakage level.

[0044] In some embodiments of this application, the method further includes storing the alarm signal in an alarm record table to achieve data sharing.

[0045] The alarm record table includes: an alarm signal, used to determine the alarm content of the gas alarm detector; and an alarm time, used to determine the time when the alarm signal was sent.

[0046] In this embodiment, the alarm signal is stored in an alarm log table to achieve data sharing, enabling other systems or personnel to promptly understand and handle relevant situations. The alarm log table plays a crucial role in this process, recording all alarm information in detail, allowing for widespread data sharing and utilization. The alarm log table mainly includes two important parts: alarm signal and alarm time. The alarm signal refers to the abnormal signal detected by the gas alarm detector. This signal clearly indicates the specific content of the alarm, such as what type of gas leaked or which part of the detector malfunctioned. The alarm time refers to the specific time the alarm signal was issued. This time information is crucial for determining the moment the alarm occurred and for subsequent emergency handling. Through such recording, it can be ensured that relevant personnel can react quickly and take effective measures to handle the problem when an alarm event occurs.
