Technical Field

[0001] The present invention relates to the technical field of fire protection engineering, and particularly to a fire alarm linkage method, system, device and medium based on heterogeneous devices. Background Art

[0002] In the networking application of existing fire alarm systems, generally only the networking between fire alarm main controllers of the same series and the same model is supported, and the information interaction of such same-specification main controllers is realized by adding a graphic display device. However, with the renovation and upgrade of building fire protection systems, the main controller devices installed in different periods often come from different manufacturers or different series, and their communication protocols, data formats, and interface standards are incompatible with each other, resulting in a lack of effective networking implementation methods between old and new fire alarm main controllers.

[0003] Existing graphic display devices are usually bound to specific main controller models and cannot be compatible with other series or third-party devices. If all main controllers are directly replaced, problems such as high renovation costs and long construction periods will be faced; if the original system is retained and an attempt is made to network with the new system, due to the lack of a unified data interaction standard, information collection, summary, and transmission between the old and new systems cannot be carried out, forming information islands. The lack of information communication between systems results in the control center being unable to achieve cross-system synchronous information display, transmission, and control, and the fire protection devices cannot form an effective linkage, seriously restricting the overall response ability and safety guarantee level of the fire protection system. Summary of the Invention

[0004] The present invention provides a fire alarm linkage method, system, device and medium based on heterogeneous devices, and its main purpose is to improve the linkage level of fire protection devices.

Based on the equipment action commands, the preset fire-fighting equipment is activated using the preset second type of fire alarm host to obtain the equipment linkage feedback signal. The second type of fire alarm equipment is a device that uses a different communication protocol than the first type of fire alarm equipment.

[0006] Optionally, the process of encapsulating the on-site fire alarm information to obtain the host's initial alarm signal includes: Obtain the alarm device address, event type, and status value from the on-site fire alarm information to obtain the fire alarm address, alarm event type, and fire alarm status.

[0009] Optionally, the fire alarm control panel model identification model includes convolutional layers, attention layers, fully connected layers, and a softmax classifier. The step of inputting the standard format alarm data sample into the preset fire alarm control panel model to obtain the alarm control panel model of the first type of fire alarm control panel includes: The standard format alarm data sample is input into the fire control panel model identification model, and the data features are extracted using the convolutional layer to obtain the alarm data features; The alarm data features are weighted and averaged using the attention layer to obtain weighted alarm data features. The fully connected layer is then used to integrate the weighted alarm data features to obtain a feature classification vector. The probability distribution vector of each preset model category is obtained by using the softmax classifier to calculate the probability of the feature classification vector. Extract the target probability value from the probability distribution vector of each preset model category, and use the preset model category corresponding to the target probability value as the alarm host model of the first type of fire alarm host.

[0010] Optionally, the step of mapping the unified alarm information to a preset base map to obtain the alarm point location and alarm point device identifier includes: Extract the identifier code of the point to be mapped from the unified alarm information and obtain the base map database, wherein the base map database includes a mapping relationship table, and the mapping relationship table includes the point number, the base map labeled equipment area and the equipment identifier; The identification code of the point to be mapped is compared with the point number in the mapping table to obtain the comparison result; Based on the comparison results, the device area corresponding to the identifier code of the point to be mapped is located on the preset base map to obtain the location of the alarm point, and the device identifier of the alarm point location is associated with it to obtain the device identifier of the alarm point.

[0018] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0019] This application provides a fire alarm linkage method based on heterogeneous devices.

The server includes, but is not limited to, a single server, a server cluster, a cloud server, or a cloud server cluster.

[0020] Reference Figure 1 The diagram shown is a flowchart illustrating a fire alarm linkage method based on heterogeneous devices according to an embodiment of the present invention. In this embodiment, the fire alarm linkage method based on heterogeneous devices includes the following steps S1-S5: S1. Obtain on-site fire alarm information, encapsulate the on-site fire alarm information to obtain the host initial alarm signal, perform dynamic protocol tracking and field semantic parsing on the host initial alarm signal to obtain structured alarm information.

[0021] Understandably, by encapsulating on-site fire alarm information and performing dynamic protocol tracking and field semantic parsing, the original alarm signals are converted into structured alarm information, enabling alarm data from different models of fire alarm control panels to be uniformly identified and parsed.

[0022] Among them, the initial alarm signal of the host refers to the original alarm data packet generated by the first type of fire alarm host after encapsulating and processing the on-site fire alarm information. It conforms to the host's own private communication protocol format and has not yet undergone protocol conversion. Its format is strongly related to the specific host model and cannot be directly recognized by other hosts of different models.

[0023] Structured alarm information refers to alarm data extracted and recombined into a unified format after dynamic protocol tracking and field semantic parsing of the initial alarm signal of the host. It eliminates the differences in private protocols of different hosts and presents them in a standardized field structure (such as location number, alarm type, timestamp, etc.), which facilitates subsequent protocol conversion and cross-system processing.

[0024] Further, the process of encapsulating the on-site fire alarm information to obtain the host's initial alarm signal includes: Obtain the alarm device address, event type, and status value from the on-site fire alarm information to obtain the fire alarm address, alarm event type, and fire alarm status. The fire alarm address, the alarm event type, and the fire alarm status are encapsulated into a data packet structure of a preset length to obtain a fire alarm data packet; A preset protocol header, preset checksum, and preset end flag are added to the fire alarm data packet to obtain the initial alarm signal of the host.

[0025] Among them, the alarm device address refers to the unique number or code of the on-site detection device in the fire alarm system, which is used to identify the specific device from which the alarm originates; the event type refers to the classification identifier of the alarm information, such as fire alarm, fault, feedback, supervision, etc.; the status value refers to the specific value or code describing the current working status of the device, such as normal (0), fire alarm (1), fault (2), etc. The three together constitute the core field of on-site fire alarm information, which is used to determine the source, nature and severity of the alarm.

[0026] The protocol header is a fixed sequence of bytes added at the beginning of the data packet to identify the communication protocol version, data packet type, or synchronization information. The checksum is a redundant check field calculated based on the data packet content using a specific algorithm (such as CRC or checksum) to verify the integrity of data transmission. The end marker is a specific character or byte sequence added to the end of the data packet to identify the termination boundary of the data packet. These three elements together constitute the frame structure of the host's initial alarm signal, ensuring that the signal is correctly identified, verified, and parsed in the communication link.

[0027] Furthermore, the step of performing dynamic protocol tracing and field semantic parsing on the initial alarm signal of the host to obtain structured alarm information includes: The communication data stream of the initial alarm signal of the host is obtained to obtain the original communication data packet; The flow of the original communication data packets is traced, and a fixed field sequence in the original communication data packets is identified based on the flow of the data packets to obtain a candidate set of protocol fields; Acquire alarm data for different event types, compare the protocol field candidate set with the alarm data for different event types to obtain field differences, and construct a field semantic mapping table based on the field differences; Based on the field semantic mapping table, the original communication data packet is segmented and semantically labeled to obtain structured alarm information, wherein the structured alarm information includes host identifier, device number, device type, event type and location information.

[0028] Among them, the original communication data packet refers to the unparsed underlying binary data unit obtained from the communication data stream of the initial alarm signal of the host. It completely retains the original communication format sent by the first type of fire alarm host, including original fields such as protocol header, data payload, and check bit, and is the basic data source for subsequent protocol tracing and field parsing.

[0029] Among them, data packet flow refers to the transmission direction and arrangement sequence characteristics of the original communication data packets in the communication sequence, including the order of data packets, the positional offset of fields within data packets, and the structural change patterns between data packets of different event types, which is used to identify the distribution patterns of fixed and variable fields in data packets.

[0030] The protocol field candidate set refers to the set of candidates that may constitute protocol fields obtained by tracing the flow of data packets and identifying fixed field sequences in the original communication data packets. It includes information such as the position offset of the field, the length of the field, and the field value rules, providing a basic reference for subsequent field comparison and semantic parsing.

[0031] Among them, field differences refer to the variation patterns in field values, field lengths, or field existences between different event types after comparing the candidate set of protocol fields with alarm data of different event types. By analyzing field differences, the semantic information carried by each field can be inferred, such as distinguishing device number, event type, status value, etc.

[0032] The field semantic mapping table is a reference table constructed based on field differences to map the field positions in the original communication data packet to specific semantic information. It defines the position offset, field length, and corresponding semantic meaning of each field in the data packet, such as host identifier, device number, device type, event type, and location information. It is the core basis for realizing field segmentation and semantic annotation.

[0033] S2. Perform protocol conversion on the structured alarm information to obtain unified alarm information, and identify the alarm host model of the first type of fire alarm host based on the unified alarm information.

[0034] Understandably, by converting structured alarm information into unified alarm information and automatically identifying the model of the first type of fire alarm control panel based on the unified information, the standardization of alarm data across models and the adaptive identification of control panel models can be achieved.

[0035] Among them, the first type of fire alarm host refers to the source fire alarm host that receives on-site fire alarm information. It can be an old system host, responsible for encapsulating and processing on-site fire alarm information, converting it into host initial alarm signal that conforms to its own communication protocol format, and serving as the initiator of alarm information in cross-system networking schemes.

[0036] Unified alarm information refers to standardized alarm data that conforms to standard communication protocols (such as MODBUS / TCP / IP) generated after the structured alarm information is converted by the communication protocol conversion card. It eliminates the differences in private protocols between different series and models of fire alarm control panels, presents the alarm content in a unified format, and facilitates the central control software to perform subsequent point mapping and linkage processing.

[0037] Among them, the alarm host model refers to the specific product model of the first type of fire alarm host identified by the protocol characteristics, data format or specific field identifier in the unified alarm information. It is used to determine the communication protocol specifications, data parsing rules and linkage logic compatibility of the host, and is a prerequisite for realizing information exchange and collaborative linkage between hosts across series and models.

[0038] Further, the step of identifying the alarm host model of the first type of fire alarm control panel based on the unified alarm information includes: The alarm data stream in the unified alarm information is obtained, and the alarm data stream is cleaned and normalized to obtain alarm data samples in a standard format. The alarm data sample in the standard format is input into the preset fire alarm control panel model recognition model to obtain the alarm control panel model of the first type of fire alarm control panel.

[0039] Among them, the alarm data stream refers to the data sequence of unified alarm information output by the communication protocol conversion card and continuously transmitted in the central control software. It contains standardized alarm data from the first type of fire alarm host and is the data source for subsequent data cleaning and format normalization processing.

[0040] Among them, the standard format alarm data sample refers to the alarm data that conforms to the preset input specifications after the alarm data stream has been cleaned and normalized. It eliminates noise, redundancy and format differences in the original data and presents them with a unified feature dimension, which is used to input the fire control panel model for model identification.

[0041] Among them, the fire alarm control panel model identification model refers to a pre-trained machine learning or deep learning model that takes standard format alarm data samples as input, learns the protocol characteristics, field distribution patterns or data patterns in the alarm data, and outputs the corresponding alarm control panel model to achieve adaptive identification of communication protocols across series and models of control panels.

[0042] Among them, the alarm host model refers to the specific product model of the first type of fire alarm host determined after classifying and identifying alarm data samples in standard format through the fire host model identification model. It is used to guide subsequent protocol parsing rule calls, linkage logic adaptation, and cross-system instruction generation.

[0043] The fire alarm control panel model identification model includes a convolutional layer, an attention layer, a fully connected layer, and a softmax classifier.

[0044] Further, the step of inputting the standard format alarm data sample into a preset fire alarm control panel model identification model to obtain the alarm control panel model of the first type of fire alarm control panel includes: The standard format alarm data sample is input into the fire control panel model identification model, and the data features are extracted using the convolutional layer to obtain the alarm data features; The alarm data features are weighted and averaged using the attention layer to obtain weighted alarm data features. The fully connected layer is then used to integrate the weighted alarm data features to obtain a feature classification vector. The probability distribution vector of each preset model category is obtained by using the softmax classifier to calculate the probability of the feature classification vector. Extract the target probability value from the probability distribution vector of each preset model category, and use the preset model category corresponding to the target probability value as the alarm host model of the first type of fire alarm host.

[0045] Among them, alarm data features refer to the feature vectors that reflect the local patterns and structural regularities of alarm data after feature extraction from standard format alarm data samples through convolutional layers. They retain the key information in the alarm data and are the basic feature representations for subsequent attention weighting and classification recognition.

[0046] Among them, weighted alarm data features refer to the feature vector obtained by weighting alarm data features using the attention layer. By assigning different weights to features of different dimensions, the contribution of key features to the recognition results is enhanced, and the influence of redundant or irrelevant features is suppressed, thereby improving the accuracy of model recognition.

[0047] Among them, the feature classification vector refers to the high-dimensional feature vector obtained after integrating the features of the weighted alarm data using the fully connected layer. It maps the weighted features output by the attention layer to the feature space corresponding to the preset number of model categories, providing a discriminative feature representation for subsequent Softmax classification.

[0048] The probability distribution vector refers to the set of probability values ​​corresponding to each preset model category obtained after calculating the probability of the feature classification vector using the Softmax classifier. Each probability value represents the confidence level of the alarm data sample belonging to the corresponding model category, and the sum of the probabilities of all categories is 1.

[0049] Among them, the preset model category refers to all possible fire alarm control panel model classifications predefined during the training phase of the fire control panel model recognition model. Each category corresponds to a specific product model. The category corresponding to the highest probability value in the probability distribution vector output by the model through the Softmax classifier is the recognition result.

[0050] The target probability value refers to the maximum probability value extracted from the probability distribution vector, which represents the model's maximum confidence in the recognition result. The preset model category corresponding to this maximum probability value is the alarm host model recognition result of the first type of fire alarm host.

[0051] The fire alarm control panel model includes the following components: Convolutional layer (CVL) is the feature extraction component, which uses a convolutional kernel to perform sliding window calculations on the input standard-format alarm data samples to extract local features and pattern regularities, outputting alarm data features; Attention layer (ADL) is the feature weighting component, which calculates attention weights for alarm data features and performs weighted processing to enhance the importance of key feature dimensions and suppress redundant information, outputting weighted alarm data features; Fully connected layer (WCL) is the feature integration component, which maps the weighted alarm data features to a feature space corresponding to the preset number of model categories, extracts high-level semantic features through nonlinear transformations, and outputs a feature classification vector; Softmax classifier (Softmax) is the classification output component, which normalizes the probability of the feature classification vector, converts the feature vector into a probability distribution for each preset model category, outputs a probability distribution vector, and takes the category corresponding to the highest probability value as the model recognition result.

[0052] S3. Map the unified alarm information to the preset base map to obtain the alarm point location and alarm point device identifier.

[0053] Understandably, by mapping unified alarm information to preset base maps, abstract alarm codes are converted into specific alarm point locations and device identifiers, enabling monitoring personnel to intuitively and quickly locate the source of the alarm.

[0054] The preset base map refers to the building floor plan data and its associated point mapping information that are pre-stored in the central control software. It is used to convert the abstract unified alarm information into a visual alarm location display.

[0055] The alarm point location refers to the specific area location on the preset base map determined by point mapping. It is presented in the form of equipment area marked on the base map to intuitively show the actual building area where the alarm occurred (such as floor, room, corridor or fire compartment), so that monitoring personnel can quickly locate the fire scene.

[0056] Among them, the alarm point device identifier refers to the identification information of the specific detection device associated with the alarm point location, which is determined through point mapping. It includes the device type (such as smoke detector, manual alarm button, fire hydrant button, etc.) and device number, which is used to identify the specific device from which the alarm originates, so as to facilitate the judgment and execution of subsequent linkage logic.

[0057] Furthermore, the step of mapping the unified alarm information to a preset base map to obtain the alarm point location and alarm point device identifier includes: Extract the identifier code of the point to be mapped from the unified alarm information and obtain the base map database, wherein the base map database includes a mapping relationship table, and the mapping relationship table includes the point number, the base map labeled equipment area and the equipment identifier; The identification code of the point to be mapped is compared with the point number in the mapping table to obtain the comparison result; Based on the comparison results, the device area corresponding to the identifier code of the point to be mapped is located on the preset base map to obtain the location of the alarm point, and the device identifier of the alarm point location is associated with it to obtain the device identifier of the alarm point.

[0058] Among them, the point identification code to be mapped refers to the field value extracted from the unified alarm information and used to identify the unique code of the alarm device. It serves as the input key value for point mapping and is used to query the corresponding background annotation device area and device identifier in the mapping relationship table.

[0059] The base map database refers to the data set stored in the backend of the central control software, used to manage the base map of building floor plans and the mapping relationship between points. It includes base map files, mapping relationship tables, equipment information and other data, providing basic data support for point mapping.

[0060] The mapping table is a core data table stored in the base map database. It is used to establish a one-to-one correspondence between the location number and the equipment area and equipment identifier marked on the base map. It is a key data structure for realizing the transformation from abstract alarm code to visual alarm location.

[0061] Among them, the point number refers to the coded field used to uniquely identify the fire detection equipment in the mapping relationship table. It corresponds to the point identification code to be mapped in terms of value and format, and is the primary key field for matching and comparison during the point mapping process.

[0062] Among them, the device area marked on the base map refers to the specific area location information that is associated with the point number in the mapping relationship table and is pre-marked on the preset base map. It describes the building location (such as floor, room, fire compartment) where the alarm device is located and is used to locate the alarm point on the base map.

[0063] Among them, the device identifier refers to the identification information associated with the location number in the mapping relationship table, which is used to describe the specific attributes of the alarm device. It includes the device type (such as smoke detector, manual alarm button) and device number, which is used to identify the specific device from which the alarm originates.

[0064] The comparison result refers to the status information obtained after matching the identifier code of the point to be mapped with the point number in the mapping relationship table. It includes two statuses: successful matching or failed matching. When the matching is successful, the corresponding base map annotation device area and device identifier are returned for subsequent base map positioning and device association.

[0065] S4. Generate a linkage control command based on the location of the alarm point, the device identifier of the alarm point, and the model of the alarm host.

[0066] Understandably, by combining the location of the alarm point, the identification of the alarm point equipment, and the model of the alarm host, linkage control commands are generated to ensure coordinated action of fire-fighting equipment and improve the accuracy and compliance of linkage.

[0067] Among them, the linkage control command refers to the standardized command generated by combining the alarm point location, alarm point equipment identification and alarm host model with the national standard linkage logic to control the action of fire-fighting equipment. It includes information such as target equipment identification, action type (such as start, stop), and action parameters, and is encapsulated according to the communication protocol format of the target host, and is used to drive the second type of fire alarm host to start the corresponding on-site fire-fighting equipment.

[0068] S5. Decompose the linkage control command into equipment action commands. Based on the equipment action commands, use the preset second type of fire alarm host to start the preset fire equipment and obtain the equipment linkage feedback signal.

[0069] Understandably, by decomposing the linkage control command into device action commands that the target host can execute, and then activating the corresponding fire-fighting equipment by the second type of fire alarm host, cross-model host device linkage control is realized, and a closed loop is formed through feedback signals to ensure that the action is executed in place.

[0070] The second type of fire alarm equipment is a device that uses a different communication protocol than the first type of fire alarm equipment.

[0071] The second type of fire alarm control panel refers to the target fire alarm control panel that receives linkage control commands and executes the activation actions of fire-fighting equipment. It can be a different series or model of the control panel than the first type of fire alarm control panel, using different communication protocols. It can be used as a new fire alarm control panel and as the execution end of linkage control in cross-system networking schemes, responsible for parsing equipment action commands and driving the on-site fire-fighting equipment to act.

[0072] Among them, the equipment action command refers to the specific control command generated by decomposing and converting the linkage control command according to the communication protocol format of the second type of fire alarm host. It includes information such as the address of the target fire equipment, the action type (such as start, stop) and action parameters, and is used to drive the second type of fire alarm host to perform specific equipment control operations.

[0073] Among them, fire-fighting equipment refers to terminal execution equipment installed at the fire scene for fire prevention, alarm, fire extinguishing or evacuation, including but not limited to smoke exhaust fans, fire pumps, fireproof rolling shutters, audible and visual alarms, fire broadcast systems, gas extinguishing devices, etc., which are started or stopped by the Class II fire alarm host according to the equipment action instructions.

[0074] Among them, the equipment linkage feedback signal refers to the status signal returned by the Class II fire alarm host or field equipment after the fire equipment executes the equipment action command, which is used to confirm the execution status of the action. It includes status information such as successful equipment start-up, failure to start-up, equipment failure, and action completion, which is used to form a closed-loop verification of linkage control to ensure that the fire equipment has acted correctly according to the command.

[0075] Furthermore, after activating preset fire-fighting equipment using the second type of fire alarm control panel based on the device action command and obtaining the device linkage feedback signal, the method further includes: The alarm location is displayed on a preset electronic map based on the location of the alarm point, and the device identifier of the alarm point and the model of the alarm host are marked.

[0076] Among them, the electronic map refers to the interactive graphical interface in the central control software used to visualize the building structure and the distribution of fire-fighting equipment. It is built based on the building floor plan base map in the base map database, and marks the alarm point location, associated equipment identification and alarm host model at the corresponding location according to the point mapping results. The alarm information is presented intuitively through flashing, highlighting and other methods, which makes it easy for monitoring personnel to quickly locate the fire scene and take corresponding measures.

[0077] In this embodiment of the invention, a communication protocol conversion card is debugged and parameter adaptation and network connectivity are completed to obtain a debugged control unit. A first-type fire alarm control panel encapsulates the on-site fire alarm and obtains structured alarm information through dynamic protocol tracking and field semantic parsing. The communication protocol conversion card converts the structured information into unified alarm information and identifies the control panel model. Central control software is acquired, and the unified alarm information is mapped to a preset base map to obtain the alarm point location and device identifier. Linkage control commands are generated according to national standard linkage logic. These commands are decomposed into device action commands executable by a second-type fire alarm control panel, activating the fire equipment and obtaining linkage feedback signals.
