[0068] Step S150, based on the information of people who enter the cultural and tourism venue in the same batch, the location information of the designated person in the cultural and tourism venue is obtained to rescue the designated person.

[0069] In a specific embodiment, the present invention proposes a digital fire control method applied to cultural and tourism venues. By integrating the Internet of Things, big data analysis, AR guidance, intelligent positioning and remote monitoring technology, it monitors the status of fire-fighting equipment and the location of personnel in real time, and provides dynamic evacuation routes in emergency situations, ensuring efficient response in emergencies such as fires and minimizing casualties and property losses.

[0070] See also Figure 2 As shown, in this embodiment, it includes: a server terminal, multiple interactive panels and multiple locators. Among them, the interactive panel can be an AR panel, which can not only improve the safety experience and navigation effect of tourists, but also serve as a communication device with the locator. The communication method between the server terminal and the interactive panel, and between the interactive panel and the monitor is usually optical fiber communication. Considering special circumstances, such as fire, the backup communication method can adopt Lora or NB-lot communication.

[0071] In this embodiment, the server terminal is also connected to a database system, and the database stores information of each node (interactive panel). The communication method between the interactive panel and the tracker and between the tracker and the tracker is Bluetooth communication. It should be noted that the distance of Bluetooth communication generally does not exceed 10m, but this does not mean that an interactive panel must be arranged within 10m, that is, the interactive panel can generally be set inside the fork in the road indoors. The locator includes a tracker and a monitor. The locator can be integrated into the monitor of the cultural and tourism equipment respectively, for example, it can be set in the glass window cabinet of the cultural and tourism equipment, and the inside of the temporary pass worn by the tourist can be used as the location of the tracker.

[0072] In this embodiment, steps 1 to 7 are included.

[0073] Step 1: Receive heartbeat data between each monitor and the interactive panel in real time.

[0074] Among them, heartbeat data is the basic concept in communication, which is used to determine whether the communication is connected online.

[0075] Step 2, in response to an abnormality in the received heartbeat data, such as an alarm message or no heartbeat data is received within a specified time, different strategies are given. For "issuing an alarm message", step 4 is executed, otherwise, step 3 is executed.

[0076] Step 3, further determine whether the monitor that does not receive the heartbeat data on a regular basis fails or generates an alarm.

[0077] It should be noted that an AR panel can usually be associated with multiple monitors to determine whether the data of other monitors around the monitor that has not received heartbeat data is abnormal, so as to distinguish whether the monitor is in an alarm state or a fault state.

[0078] Step 4: The interactive panel collects the flow data information of the tracker.

[0079] When the alarm is confirmed in step 3, the communication function of the tracker is activated. Since the interactive panel and the tracker are connected via Bluetooth, the interactive panel can only receive the tracker within a certain range. It can be expressed as:

[0080] .

[0081] in, Indicates the tracker ID. Indicates the current timestamp, Indicates that the tracker is numbered The distance of the tracker (ranging information), where , Indicates timestamp The number of all other trackers that can be received.

[0082] In this embodiment, the distance measurement information may generally adopt Bluetooth Low Energy (BLE) distance measurement technology, which generally uses RSSI (Received Signal Strength Indicator) to estimate the distance between two devices, and the stronger the RSSI value, the closer the distance between the devices.

[0083] Specifically, two positioning tags continuously exchange signals via BLE, and the receiver estimates the distance between the two devices by measuring the received signal strength (RSSI) and combining it with the known signal strength attenuation model. Although the accuracy of BLE ranging is relatively low, usually within the range of 8-10 meters, its power consumption is low and it is suitable for use in devices that do not require high accuracy and need to run for a long time, in order to reduce power consumption and increase battery life.

[0084] It should be noted that the coverage of the interactive panel should cover all forks in the road. For passages without forks in the road, the interactive panel may not be set.

[0085] Step 5: Determine the current optimal escape route in real time based on the traffic data information.

[0086] Step 5 specifically includes step 5.1 to step 5.3.

[0087] Step 5.1, based on the traffic data information, determine the crowd density value of the current node.

[0088] Specifically, nodes (interaction panel) The population density value It can be shown as follows:

[0089] ,

[0090] .

[0091] in, Indicates that it is from The crowd density information obtained from the traffic data information of the tracker is numbered All data flow information of the interactive panel at time, according to Sort the data by size from small to large, and select the top 30% to 50% of the data flow information as the collection .

[0092] Step 5.2, based on the crowd density value of the node and the crowd density value of the historical road section, calculate the crowd density value of the road section.

[0093] Step 5 is executed regularly (for example, every 2s to 5s) according to the specific situation on site. Therefore, when step 5.2 is executed for the first time, the historical weight of the road section can be initialized to the average of the crowd density values ​​of the two nodes.

[0094] Among them, the crowd density value of the road section can be expressed as follows:

[0095] .

[0096] In the formula, is the time interval, and Respectively represent nodes With Node The road section between and The crowd density value under and is the directivity coefficient, respectively represents the interactive panel Interaction Panel Is it pointing to this section? Refers to the node With Node The number associated with the road segment between The monitor at the time The value below, Refers to the number The impact of the monitor on the road section.

[0097] It should be noted that if the interactive panel points to the road section, the corresponding directivity coefficient value is 1, otherwise it is -1. The interactive panel points to the road section, which means that the AR panel points the crowd to the optimal escape route.

[0098] Step 5.3, based on the crowd density value of the road section, determine the current optimal escape route at each node.

[0099] Specifically, the crowd density value of a road section is equivalent to the weight of the road section.

[0100] It should be noted that in this timed message, since the interactive panel receives Bluetooth information from multiple locators every second, coupled with alarm anomalies, Bluetooth communication will be interrupted. Therefore, it is necessary to combine the Bluetooth communication between trackers and trackers to obtain a reliable node population density value, and each interactive panel corresponds to a node.

[0101] Step 6: For people who enter the venue in the same batch, firstly, the information of the people who enter the cultural and tourism venue in the same batch can be further determined based on the traffic data information before the fire.

[0102] Specifically, during the escape process, tracking alarm measures can be added in a timely manner. For example, if the flow data information of a companion does not include the ID information of other companions for three consecutive times (the number can be set randomly as needed, depending on the frequency of the appearance of the same person information in the flow data information within a specific time), an alarm will be issued. The ID information needs to be pre-configured before entering the venue.

[0103] Step 7: Rescue designated persons (such as children) based on the traffic data information.

[0104] Specifically, when family members are separated from children or other people with special care needs, they can request location-based rescue of the children or other people with special care needs contained in the traffic data information based on the traffic data information, or they can search and rescue on their own based on the location of the location.

[0105] In this embodiment, by providing full-scene real-time monitoring, fire hazards such as fire or smoke can be accurately detected. In an emergency, the AR panel guides tourists through the best escape route, realizes remote monitoring and maintenance management of the status of fire-fighting equipment, and ensures the real-time reliability of the equipment. It is also based on the positioning system to track the location of tourists and staff in real time to ensure the efficiency of emergency evacuation. In addition, the visualization of system data can provide managers with clear on-site status and decision-making basis. The implementation of this method only requires AR panels and monitors, which are small and convenient, and can ensure that the positioning equipment and locators can run for a long time with low power consumption, while ensuring a wide range of coverage. The fire sensors, locators, AR panels and server terminals are seamlessly integrated to ensure the collaborative work of the system.

[0106] In this embodiment, it is necessary to first install fire monitoring sensors and equipment, and install a variety of fire sensors (such as smoke detectors, temperature sensors, gas detectors, etc.) in cultural and tourism venues to monitor fire hazards in real time. Under the premise that the structure of the ancient building allows, invisible or micro-sensing equipment can be used to minimize the impact on the appearance of the building. Subsequently, the AR panel and interactive guidance system are deployed, and AR panels are set up in the main passages and entrances and exits to display historical and cultural information at ordinary times and as evacuation guidance equipment in emergencies. Through real-time data analysis and combined with the building layout, the system dynamically generates the best evacuation path when a fire occurs and displays it on the AR panel. After that, the positioning system is configured, and the fixed positioning device can be installed in the cultural relics display cabinet, and the mobile positioning device is integrated in the temporary pass of the tourists to track the location information of the tourists in real time to ensure that effective evacuation management can be carried out according to the distribution of the flow of people in the event of an emergency. The server terminal is responsible for collecting data from various sensors and positioning devices for centralized analysis. All fire monitoring equipment is connected to the server via Ethernet or optical fiber communication to ensure efficient data transmission.

[0107] In this embodiment, a backup communication system is set up using LoRa or NB-IoT communication methods to deal with network disconnection problems in special circumstances such as fires. Through the server terminal, the operating status of all fire-fighting equipment is remotely monitored in real time. When the equipment fails or a hidden danger is detected, the system automatically issues a maintenance reminder and generates a detailed report for reference by maintenance personnel. Maintenance tasks and operation records are digitally managed through the platform to ensure the transparency and traceability of each maintenance process. When the sensor detects a fire signal, the system automatically triggers an alarm to notify the fire brigade and management personnel. The AR panel displays the escape route in real time and prompts tourists and staff to evacuate quickly through sound and light. Managers use the system to grasp the location of the fire and the distribution of personnel in real time, and command evacuation and rescue operations. The system stores all monitoring data, fire event logs, evacuation records, etc. in the database for subsequent analysis. Through big data analysis, managers can optimize the layout of fire-fighting equipment, adjust maintenance strategies, and improve the overall fire management level of the venue.

[0108] The digital fire control system for cultural and tourism venues provided by the present invention is described below. The digital fire control system for cultural and tourism venues described below and the digital fire control method for cultural and tourism venues described above can be referenced to each other.

[0112] The fire route planning module is used to obtain the crowd density value of the current node based on the traffic data information, and calculate the crowd density value of the current section based on the crowd density value combined with the crowd density value of the historical section, so as to determine the optimal escape route for the section corresponding to each node.
