Description

Technical Field

[0001] This invention belongs to the field of property fire protection based on digital twins, specifically relating to a centralized fire protection control system and method based on dynamically generated digital twins. Background Technology

[0002] According to the national standard "Code for Design of Automatic Fire Alarm Systems GB50116-2013", for protected objects with two or more fire control rooms, or protected objects already equipped with two or more centralized alarm systems, a control center alarm system should be adopted. The design of a control center alarm system should comply with the following provisions: When there are two or more fire control rooms, a main fire control room should be designated; the main fire control room should be able to display all fire alarm signals and linkage control status signals, and control important fire-fighting equipment; fire-fighting equipment in each sub-fire control room can transmit and display status information to each other, but should not control each other.

[0003] According to the current regulations and future development trends of fire control rooms in various regions: fire control rooms should be managed by their management units under a 24-hour duty system, with no fewer than two people on duty per shift; if all control functions of the fire control room can be remotely operated through the city's fire remote monitoring system, no fewer than one person on duty per shift.

[0004] According to the above regulations, during the planning and construction phases of property fire protection systems, the fire information from the fire control sub-control rooms must be connected to the centralized control room to achieve complete point-to-point control, and the networks between the fire control sub-control rooms must not interfere with each other.

[0005] In the actual evolution of fire protection construction, introducing fire signals from sub-control rooms to a centralized control room requires not only the construction of an independent network but also multi-line control capabilities from the centralized fire control center. However, the current centralized control room suffers from a lack of a bus network; multiple fire control panels deployed in various sub-control rooms are not interconnected, resulting in centralized monitoring being merely "monitoring without controlling," failing to meet fire safety regulations. On the other hand, to achieve centralized management, there are currently two main approaches: (1) Some properties deploy fire control panels in the fire control sub-control room and the central control room respectively, and use a direct connection between the two panels to achieve centralized networking of data in the sub-control room. In this method, the uplink and downlink data share a single data channel. When the downlink data volume is large, it will affect the transmission of uplink monitoring and alarm data; and the capacity utilization rate of the fire control panel in the central control room is less than 10%. This method not only increases the energy consumption of the central control room and improves the power usage efficiency (PUE) value, but also significantly increases the deployment cost of the fire protection system and the cost of monitoring personnel in the central control room.

[0006] (2) Each fire control room's main unit reports data independently, making it impossible to achieve the goal of data supplementation or linkage between multiple main units.

[0007] Meanwhile, the current centralized monitoring process also suffers from problems such as the inability to promptly identify false alarms and a lack of analytical capabilities in linking monitoring alarms. This necessitates property management staff frequently visiting the site for verification. This not only increases the workload of the on-duty personnel but also requires multiple staff members to be on duty to ensure timely follow-up on issues.

[0008] This invention innovatively provides a centralized fire control system and method based on dynamically generated digital twins. By employing digital methods, it overcomes the shortcomings of existing remote control methods for fire control panels, which require full transmission of all status and button signals, leading to high implementation difficulty, long development cycles, and an inability to dynamically adapt to changes in the number of fire control panels. This allows for remote centralized control of the fire control panel.

[0009] This invention also proposes a remote verification method for the status of fire control panels based on video analysis, which avoids inconsistencies between the status data of the fire control panel and the actual equipment status caused by mistransmission or omission during the transmission of status signals, thereby improving the reliability and security of the centralized control method for fire control panels. Summary of the Invention

[0010] The purpose of this invention is to provide a fire-fighting centralized control system and method based on dynamically generated digital twins, to replace existing fire-fighting centralized control methods, and to solve the following problems in the existing fire-fighting centralized control process: First, when devices are connected point-to-point, a large amount of invalid data reporting occupies bandwidth and affects the timeliness of valid data reporting, and when downlink data is sent in batches, link congestion causes alarm data to be unable to be reported in a timely manner; Second, in the many-to-one centralized reporting and control scheme, it is impossible to automatically complete the false alarm suppression, missed alarm supplementation and point-to-point precise control.

[0011] In view of the above problems, this application provides a centralized fire protection control system and method based on dynamically generated digital twins.

[0012] The first aspect disclosed in this application provides a method for centralized fire control based on dynamically generated digital twins, the method comprising the following steps: S1: Prepare data, centrally control the system's pre-configured digital twin service and configuration files, and complete the registration and configuration of the sub-control room host; The centralized control system includes: a configuration management module for registering sub-control room hosts and configuring cascading relationships; a digital twin scheduling management module for creating and monitoring the status of digital twin services; a data receiving and distribution module for receiving requests from sub-control room hosts and distributing them to the corresponding digital twin services; and a data delivery module for sending control commands to sub-control room hosts. The digital twin module comprises a monitoring and alarm module, a fire control module, a video analytics module, a user interface module, and a database module: the monitoring and alarm module captures and processes fire alarms; the fire control module issues fire alarms and controls the hosts; the video analytics module verifies alarms and checks execution results using a video analytics model; the user interface module builds a graphical interface; and the database module stores data. Each module deploys corresponding services.

S2-2: The data receiving and distribution module of the centralized control system receives and parses the connection establishment request to obtain the host ID and request type; S2-3: If the request type is a registration request, the digital twin scheduling and management module starts the corresponding digital twin service with the host ID as the identifier, registers the access path of the user interface with the centralized control system, generates the access entry of the current host digital twin service in the centralized control system, and changes the digital twin status of the current host in the digital twin scheduling and management module.

Error correction data is periodically summarized to iteratively train the video analytics service's video analytics model.

[0013] Preferably, step S3 specifically includes the following steps: S3-1: The centralized control system receives data reported by the main unit in the sub-control room and parses the main unit ID; S3-2: If the host ID is registered and the digital twin service is running normally, the monitoring data will be forwarded to the monitoring and alarm service corresponding to the host's digital twin service; if the digital twin service is abnormal, an abnormal alarm notification for the digital twin service will be issued; if the host ID is not registered, the monitoring data will be discarded. S3-3: If the reported data is alarm data, the alarm verification process will be triggered immediately; if the reported data is monitoring data, the status of the current host panel in the digital twin service will be updated, and confirmation will be sent to the sub-control room host. The sub-control room host will then update the uplink status. S3-4: The video analytics service performs alarm verification, obtains the alarm time of the alarm data to be verified, extracts the alarm identifier from the video stream data one minute before and after the alarm time, compares it with the alarm data, and returns a confidence value to the monitoring alarm service corresponding to the current host digital twin service. S3-5: The monitoring alarm service responds based on the confidence value: if the alarm is true, a control command is sent to the control room host for fire handling, and the status of the current host panel in the digital twin service is updated; if it is a suspected alarm, alarm information is sent according to the configured channel to notify manual handling.

[0014] Preferably, step S4 specifically includes the following steps: S4-1: The user interface service of the digital twin of the control room host provides a command input keyboard, and the fire control service carries the host ID to transmit the control command data entered by the user to the monitoring and alarm service; S4-2: Send the control command data to the control module in the sub-control room; S4-3: The control module in the sub-control room forwards the control command to the corresponding sub-control room host according to the host ID in the control command; S4-4: The video acquisition module collects the execution results of the control commands and reports them to the video analysis service.

S2-2: The data receiving and distribution module of the centralized control system receives and parses the connection establishment request to obtain the host ID and request type; S2-3: If the request type is a registration request, the digital twin scheduling and management module starts the corresponding digital twin service with the host ID as the identifier, registers the access path of the user interface with the centralized control system, generates the access entry of the current host digital twin service in the centralized control system, and changes the digital twin status of the current host in the digital twin scheduling and management module.

[0032] S3: The control room host reports monitoring data, the centralized control system forwards the data to the corresponding digital twin service, executes alarm response, and verifies the alarm through video analysis service.

[0033] like Figure 3 As shown, the specific steps include: S3-1: The centralized control system receives data reported by the main unit in the sub-control room and parses the main unit ID; S3-2: If the host ID is registered and the digital twin service is running normally, the monitoring data will be forwarded to the monitoring and alarm service corresponding to the host's digital twin service; if the digital twin service is abnormal, an abnormal alarm notification for the digital twin service will be issued; if the host ID is not registered, the monitoring data will be discarded.

[0038] For example, a residential community may have six sub-control rooms and one centralized control system. The six sub-control rooms are constructed in phases as the buildings are delivered, and are gradually connected to the centralized control system. The following example illustrates the specific implementation process of the method described in this application's embodiments, using the process of connecting two fire alarm control panels in sub-control room 05 to the centralized control system for fire alarm data reporting and centralized control as an example.

[0039] S1: Data Preparation In the centralized control system, the fire alarm control panel for sub-control room 05 is pre-configured. Configuration parameters include: sub-control room number "05", equipment serial numbers (SN) "jyw21011" and "jyw21012" respectively, and the physical location of the sub-control room "Building 8, Basement 1". After the configuration information is submitted, the system automatically generates corresponding digital twin service identifiers: Digital twin ID for host jyw21011: dt025_jyw_105_001; Digital twin ID for host jyw21012: dt025_jyw_105_002. The configuration management module in the centralized control system completes resource requests and pre-configures monitoring alarm services, video analysis services, command issuance services, and user interface services for the two hosts respectively. All services are initially set to "offline". Simultaneously, an alarm notification policy is configured: confirmed alarms are notified by telephone; suspected alarms are notified via SMS and in-system messages. All of the above configuration data are persistently stored in the database module of the centralized control system's digital twin application system.

[0040] S2: The equipment in sub-control room No. 05 is powered on and registration is initiated. After the two fire alarm control panels in sub-control room 05 are powered on and complete the network connection, they automatically turn on the host reporting switch and send a link establishment request to the centralized control system. The request message carries the device SN (jyw21011 or jyw21012) and the sub-control room number "05".

[0041] S3: Centralized control system processes power-on registration requests. After receiving a connection request, the data receiving and distribution module of the centralized control system parses the protocol content and extracts the host SN and request type. The system queries the database module to confirm that both SNs "jyw21011" and "jyw21012" are registered. Then: a registration success message is returned to the corresponding sub-control room host; the digital twin scheduling management module, using the host ID as an identifier, starts the digital twin service orchestration template, activating all service instances (including monitoring and alarm modules, video analysis modules, fire control modules, user interface modules, etc.) corresponding to dt025_jyw_105_001 and dt025_jyw_105_002; a new digital twin access point for the two hosts in sub-control room 05 is added to the centralized control system workbench, and the service status is updated to "running". If the SN is not registered, the connection is rejected and the request is discarded.

[0042] S4: Alarm Data Reporting and Forwarding S4-1: Alarm Data Reception and Routing The two main units in sub-control room 05 reported temperature alarms and slight smoke alarms, respectively. Taking main unit jyw21011 as an example: after receiving the alarm data, the data receiving and distribution module of the centralized control system parses the SN as "jyw21011" and queries the database to obtain its corresponding monitoring alarm service ID: service_alertProcess_dt025_jyw_105_001. The system forwards the alarm data to this service instance.

[0043] S4-2: Alarm Information Distribution After receiving an alarm, service_alertProcess_dt025_jyw_105_001 extracts the alarm type (temperature alarm, smoke alarm), alarm time, and alarm identifier, and sends the above information to the corresponding video analytics service instance: service_alertSysAndFix_dt025_jyw_105_001, triggering the alarm verification process.

[0044] S5: Alarm Verification and Error Correction Processing The video analytics service `service_alertSysAndFix_dt025_jyw_105_001` performs the following operations: extracts the alarm time point and obtains video stream data within one minute before and after that time; based on a pre-built video analytics model, it identifies whether there are visual features (such as smoke patterns, abnormal temperature areas, etc.) in the video that match the alarm identifier; calculates the feature matching ratio and outputs the credibility assessment result: temperature alarms with a credibility of 80% are judged as high-credibility suspected alarms; smoke alarms with a credibility of 63% are judged as low-credibility suspected alarms. The monitoring alarm service performs differentiated responses based on credibility: for temperature alarms (credibility 80%), it is considered an alarm requiring a response, immediately issuing control commands to the host `jyw21011` and initiating telephone notification; for smoke alarms (credibility 63%), manual verification is only performed by on-duty personnel through internal messages and telephone notifications.

[0045] S6: Control command issuance and execution result verification The on-duty personnel manually issue an "Activate Alarm Bell" control command through the digital twin user interface module of the main unit jyw21011 in sub-control room 05 of the centralized control system. The user interface module transmits the command and the main unit ID (jyw21011) to the fire control module; the fire control module calls the data distribution module to send the command to the control module in sub-control room 05; the sub-control room control module routes the command to the fire control unit jyw21011 according to the main unit ID; the main unit executes the command, and the alarm bell indicator light starts flashing; the sub-control room video acquisition module captures the execution scene in real time and reports the video stream to the video analysis module of the centralized control system; the video analysis module recognizes the "alarm bell indicator light flashing" state, confirms the command execution is successful, and returns the verification result to the fire control module of the digital twin main unit; the fire control module closes the command flow accordingly, completing the closed-loop control.

[0046] In summary, the fire-fighting centralized control method based on dynamically generated digital twins provided in this application has the following technical effects: (1) It solves the problems of high cost and low equipment utilization rate of point-to-point control in the existing fire centralized control system. It also solves the problems of the inability of centralized monitoring to achieve automated control and the mutual interference of uplink and downlink messages in the link when point-to-point connection is used in the existing fire centralized control system.

[0047] (2) The host digital twin application system in this method can automatically complete the access of the host in the fire control room and dynamically generate a host digital twin with a control panel. The video analysis and monitoring measures of the host in the fire control room can not only reduce false alarms, but also improve the fire prevention capabilities of centralized monitoring through shared data training models.
