Description

Technical Field

[0001] This invention belongs to the field of fire protection technology, and in particular relates to an integrated emergency evacuation system and its operation method for escape and rescue. Background Technology

[0002] With economic development and the accelerating pace of urban construction, the number of large public buildings, such as shopping malls, hospitals, office buildings, rail transit, and schools, is gradually increasing. These buildings often have complex internal spaces and dense populations, making emergency evacuation difficult in the event of a fire, which can easily lead to mass casualties. Therefore, these public places have become the focus of emergency fire supervision by departments at all levels and the key to social fire prevention and control.

[0003] However, most effective safety measures currently focus on fire prevention. Escape and rescue at fire scenes remain largely self-help oriented, with rescuers relying on personal experience and existing knowledge. Escapees often passively wait for rescue or employ incorrect self-rescue methods. To address this, many companies have launched smart fire protection systems that use positioning and navigation technology to indicate evacuation routes for trapped individuals or provide firefighters with the location of trapped people. While these systems can reduce casualties to some extent, the unpredictability and influencing factors of fires mean that the situation inside buildings only becomes increasingly complex and dangerous. Such technologies often only develop strategies for escapees or rescuers, failing to share emergency evacuation information and fire scene conditions comprehensively among relevant personnel. This can easily lead to incorrect judgments by escapees or rescuers due to information asymmetry, resulting in missed opportunities, reduced efficiency, and rescue and evacuation failing to achieve the desired results. Summary of the Invention

[0004] The purpose of this invention is to provide an integrated emergency evacuation system and operation method for escape and rescue, aiming to solve the problem that in existing smart fire protection systems, emergency evacuation information and fire scene conditions cannot be fully shared among relevant personnel, which easily leads to erroneous judgments by escapees or rescuers due to information gaps, resulting in rescue and evacuation failing to achieve the expected results.

Users can access the system through terminal devices to obtain navigation routes, pre-stored building floor plans, and location information of other users, helping the public to evacuate quickly. Simultaneously, the terminal module provides both a rescuer mode and an escaper mode. The rescuer mode includes a map marking function, allowing rescuers to mark areas of danger, congestion, etc., on the map. This marking information is then sent to the terminal devices of all other users via the emergency evacuation module. Given the complex building structures and unpredictable fire situations, in the event of an unexpected situation where fire detectors or other fire-fighting equipment fail to detect a fire alarm, rescuers can promptly notify other users through the marking information, serving as a reminder and warning to escapers and helping them avoid danger zones. The system can reduce the workload of rescue personnel.

The emergency evacuation module also uploads its communication and records with the terminal module to the cloud platform, allowing on-site commanders and the fire command center to promptly understand the situation inside the building and make more accurate and real-time judgments. This invention effectively reduces information asymmetry among people inside a fire, increases the escape probability of escapees, improves the rescue efficiency of rescue personnel, and solves the problem of untimely and inadequate information access for the fire command center at the rescue site. It maximizes the utilization of information in emergency situations, increasing the success rate of rescue efforts. Attached Figure Description

[0075] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0076] The specific implementation of the present invention will be described in detail below with reference to specific embodiments:

[0077] Example 1:

[0078] Embodiment 1 of the present invention provides an integrated emergency evacuation system for escape and rescue, see Figure 1 It includes a terminal module, a fire alarm module, an emergency evacuation module, and a cloud platform module;

[0079] The terminal module includes several terminal devices, which are used to receive and display navigation routes and user location information sent by the emergency evacuation module; it is also used to provide rescuer mode or escaper mode according to the user's identity. The rescuer mode includes a map marking function, and its marking information is sent to each terminal device through the emergency evacuation module.

[0080] The fire alarm module is used to collect alarm information from fire detectors in the building and transmit it to the emergency evacuation module.

[0081] The emergency evacuation module is used to obtain the location information of the terminal device, generate navigation routes and send them to the terminal module; transmit message information with the terminal module to realize mutual communication between users; and also to upload the information content and records of its exchanges with the terminal module to the cloud platform module.

[0082] The cloud platform module is used to store information uploaded by the emergency evacuation module and grant information sharing permissions to accessing devices.

[0083] The terminal module in this application is a portable module that realizes positioning, navigation, communication, and display functions. The terminal devices that make up the terminal module in this application include, but are not limited to: smartphones, smartwatches, fire helmets containing terminal devices, firefighter protective clothing containing terminal devices, and fire escape protective clothing containing terminal devices. The terminal devices are equipped with a display module, a wireless positioning module, an electronic compass, an electronic gyroscope, and an accelerometer. After the user carries the terminal device, the emergency evacuation module can locate the user's specific location coordinates in the building and display these location coordinates on a map in real time. The data is then uploaded to the cloud platform module via wired means such as CAN, Ethernet, or fiber optics. All users with terminal devices can view each other's locations. The fire command center and fire commanders can also access the cloud platform module through the device to view the user's location, thereby realizing real-time monitoring of the site plan. The cloud platform module includes a server, platform services, and application services. Users such as the fire command center and fire commanders can access the cloud platform module through devices such as PCs, smartphones, and tablets via wired or wireless communication methods to obtain information.

[0084] This invention provides an integrated emergency evacuation system for escape and rescue. Users can access the system via terminal devices to obtain navigation routes, pre-stored building floor plans, and location information of other users, facilitating rapid evacuation. Simultaneously, the terminal module offers both a rescuer mode and an escaper mode. The rescuer mode includes a map marking function, allowing rescuers to mark areas of danger, congestion, etc., on the map. This marking information is then sent to the terminal devices of all other users via the emergency evacuation module. Given the complex building structures and unpredictable fire situations, in the event of an unexpected situation where fire detectors or other fire-fighting equipment fail to detect a fire alarm, rescuers can promptly notify other users through the marking information, serving as a reminder and warning to escapers, helping them avoid dangerous areas, and reducing the workload of rescuers. Furthermore, the emergency evacuation... The distribution module acts as a relay module, providing a channel for users to exchange messages, enabling communication between rescuers and evacuees, or among rescuers themselves, thus improving rescue efficiency. The emergency evacuation module also uploads its communication and records with the terminal module to a cloud platform. On-site commanders and the fire command center can use this information to understand the situation inside the building in a timely manner and make more accurate and real-time judgments. This invention establishes an information chain between evacuees, rescuers, the fire command center, and rescue commanders, effectively reducing information gaps among people inside the fire scene, increasing the probability of escape for evacuees, improving rescue efficiency, and solving the problem of untimely and inadequate information access for the fire command center. It maximizes the utilization of information in emergency situations, increasing the success rate of rescue efforts.

[0085] Preferably, the terminal module includes a personnel classification unit, a personalized navigation unit, a map unit, and a communication unit;

[0086] The personnel classification unit is used to obtain and identify user identity, classifying users as rescuers or escapers. Users can choose to be rescuers or escapers on their terminal devices, and the personnel classification unit will classify the terminal into rescuer mode or escaper mode based on the user's selection.

[0087] The personalized navigation unit is used to obtain navigation routes sent by the emergency evacuation module. There are multiple navigation routes, and the personalized navigation unit filters multiple navigation routes to obtain a personalized navigation route. The main difference between rescuers and escapees is that rescuers are equipped with self-contained breathing apparatus and can pass through areas with dense smoke but no high-temperature flames. Based on this filtering condition, corresponding personalized navigation routes can be provided for rescuers and escapees respectively, to prevent escapees without breathing apparatus from accidentally entering smoky areas and getting injured, to help rescuers find trapped escapees as soon as possible, and to help escapees evacuate quickly and safely.

[0088] The map unit displays building floor plans, user location information, and personalized navigation routes. It also enables map marking, sending map markings made by rescue personnel to the emergency evacuation module and displaying the markings. The terminal module pre-stores floor plans for each floor of the building. Users can see personalized navigation prompts overlaid on the floor plans on the terminal device's display module. Rescue personnel can mark specific areas on the floor plans on the display module. Map marking categories include blocked areas, dangerous areas, searched areas, and areas requiring reinforcement. Map markings can be sent to all connected terminal devices via the emergency lighting's wireless module and simultaneously uploaded to the cloud platform module by the emergency lighting controller. Map markings are updated in real-time by rescue personnel and promptly displayed to other users and the fire command center, enabling real-time synchronization of on-site events and status information among multiple key stakeholders. This maximizes information utilization in emergency situations and improves the success rate of rescue operations.

[0089] The communication unit is used to send user-input messages to the emergency evacuation module and to receive messages sent by the emergency evacuation module. Messages include text messages and voice messages, presented in the form of messages. Compared with traditional equipment such as fire telephones, it does not require confirmation of whether someone is receiving or answering the call, eliminating the confirmation time at the beginning of communication. Moreover, text messages can be viewed repeatedly or voice messages can be listened to repeatedly, improving the success rate of information retrieval.

[0090] Preferably, the emergency evacuation module includes an emergency lighting controller and several emergency lighting fixtures distributed throughout the building. The emergency lighting controller is connected to the several emergency lighting fixtures via a terminal two-wire bus, and the emergency lighting fixtures are equipped with wireless modules. The emergency lighting controller has the ability to display floor plan graphics and information processing capabilities. The emergency lighting controller stores the protected locations, i.e., the floor plans or BIM drawings of each floor of the building, and the drawings indicate the precise installation locations of the emergency lighting fixtures.

[0091] Emergency lighting fixtures are used to locate terminal devices to obtain user location information, and to receive or transmit information to terminal devices wirelessly; emergency lighting fixtures include emergency lighting fixtures and emergency signage fixtures.

[0092] The emergency lighting controller is used to generate navigation routes and to exchange marking and message information with the terminal device through the emergency lighting. In this embodiment, the emergency lighting is equipped with a wireless module, which works with the user's terminal device via Bluetooth or satellite to achieve indoor positioning and communication functions. In some other embodiments, other wireless modules such as UWB and WiFi can also be used.

[0093] The fire alarm module includes a fire monitoring controller and several fire detectors distributed throughout the building. The fire monitoring controller is connected to the fire detectors via a terminal 2 bus. The fire monitoring controller is used to acquire the alarm status and location information of the fire detectors and send it to the emergency lighting controller. The fire monitoring controller is connected to the emergency lighting controller via wired communication, i.e., CAN or Ethernet. The fire detectors include smoke detectors, heat detectors, and composite smoke and heat detectors.

[0094] Preferably, the map unit is also used to automatically mark escaping personnel as stationary for extended periods and send the data of these automatic markings to the emergency evacuation module; it is also used to receive and display the data of these automatic markings on the building floor plan; the data of these automatic markings is uploaded to the cloud platform module by the emergency evacuation module; the automatic marking of long-term stationary states is achieved by calculating the changes in acceleration and angular acceleration of the escaping user's terminal device over a certain period of time to mark them urgently. If an escaping person remains stationary for an extended period, they may be unconscious or trapped in a dangerous situation; the principle of sending and displaying the automatic markings of long-term stationary states is the same as that of map markings, which is equivalent to alerting rescuers that the user is in danger, allowing the fire command center and all rescuers to obtain the specific location of the trapped person in a timely manner, facilitating subsequent rescue work.

[0095] Preferably, the emergency evacuation module is also used to record evacuation drills; the emergency lights record the users' location information in real time and transmit the location information to the emergency light controller for storage; the emergency lights acquire records of the location changes of the terminal devices used by the users during the evacuation drill over time, integrate them into a location data packet, and send it to the emergency light controller for storage. The location data packet contains the terminal device ID, time, and coordinate data; when it is necessary to replay the record, it is only necessary to parse the data packet in chronological order at the emergency light controller to mark the location of specific personnel, thereby constructing a record of the location changes of all personnel during the escape over time.

[0096] Example 2:

[0097] Embodiment 2 of the present invention provides an operation method for an integrated emergency evacuation system for escape and rescue. The operation method is based on the integrated emergency evacuation system for escape and rescue described in Embodiment 1. The implementation process of the map marking function in this method is described in [link to embodiment 1]. Figure 2 As shown, it includes the following steps:

[0098] S01. The user's terminal device automatically connects to the wireless module of the emergency light fixture via Bluetooth or StarFlash; in this embodiment, the wireless module of the emergency light fixture is Bluetooth or StarFlash; in some other embodiments, other wireless modules such as UWB and WiFi can also be used.

[0099] S02. Rescue personnel use terminal devices to select local areas on the building floor plan for map marking and select map marking categories;

[0100] S03. The terminal device generates a "map marker" data packet based on the marker information input by the user and sends it to the emergency lighting fixture connected to the user's terminal device. The "map marker" data packet contains the terminal device ID, building number, floor number, coordinate position (x, y) on the floor plan, map marker category, and creation time.

[0101] S04. The emergency lighting fixtures send the "map marker" data packet to the emergency lighting fixture controller via the terminal 2 bus;

[0102] S05. The emergency lighting controller parses the "map marker" data packet, synchronizes the parsed data to the cloud platform module, and saves the operation record;

[0103] S06. The emergency lighting controller sends the "map marker" data packet to all emergency lighting fixtures through the terminal two bus. The emergency lighting fixtures that receive the "map marker" data packet forward the "map marker" data packet to the connected terminal devices.

[0104] S07. The terminal device parses the "map marker" data packet and displays the parsed data on the building floor plan;

[0105] Map marker categories include blocked area markers, danger area markers, searched area markers, and areas requiring reinforcement markers; see the screenshot showing the map marker function. Figure 3 The on-site building structure is complex and there are many uncertainties. In the event of an unexpected situation where fire detectors and other fire-fighting equipment fail to detect a fire alarm, rescuers can promptly notify other users and the fire command center through map marking information. This serves as a reminder and warning to those escaping, helping them avoid dangerous areas and reducing the workload of rescuers.

[0106] The preferred implementation process for personalized navigation routes is shown below. Figure 4 As shown, it includes the following steps:

[0107] S11. The user's terminal device automatically connects to the wireless module of the emergency light fixture via Bluetooth or Starlight. After obtaining the user's location information, the emergency light fixture sends it to the emergency light fixture controller. The emergency light fixture controller generates multiple navigation routes and sends them to the terminal device through the emergency light fixture.

[0108] S12. Determine if the current user is a rescuer; if yes, exclude navigation routes that pass through Class A areas; if no, exclude navigation routes that pass through Class A or Class B areas; set the remaining navigation routes after exclusion as personalized navigation routes.

[0109] S13. Display a personalized navigation route on the current user's terminal device;

[0110] S14. The emergency lighting controller obtains the latest alarm status and location information of the fire detectors from the fire monitoring controller, regenerates multiple navigation routes, and sends them to the current user's terminal device through the emergency lighting.

[0111] S15. Determine if there is any new fire alarm information; if yes, return to step S12; if no, maintain the display of the current personalized navigation route.

[0112] Class A areas are those where both smoke detectors and heat detectors are installed, and both detectors alarm simultaneously; or areas where only a combined smoke and heat detector is installed, and both the smoke and heat detection components of the combined smoke and heat detector alarm simultaneously.

[0113] Category B areas are those where both smoke detectors and heat detectors are installed, and the smoke detector alarms while the heat detector does not; or areas where only a combined smoke and heat detector is installed, and the smoke detection part of the combined smoke and heat detector alarms while the heat detection part does not.

[0114] The main difference between rescuers and escapees is that rescuers are equipped with self-contained breathing apparatus (SCBA) and can traverse areas with dense smoke but no high-temperature flames; while in the aforementioned Class A and B areas, both Class A and B areas pose a danger to escapees, while only Class A areas pose a danger to rescuers. Users select their role as either rescuer or escapee on their terminal device. If the user selects escapee, all Class A and B areas on the map, as well as the blocked and dangerous areas marked on the map, are automatically considered impassable and avoided during personalized navigation; if the user selects rescuer, all Class A areas on the map, as well as the areas marked as blocked and dangerous, are considered impassable and avoided during personalized navigation. Blocked and dangerous areas marked on the map are considered impassable and should be avoided during personalized navigation. Other evacuation routes, including fire elevators, are usable. The personalized navigation function provides differentiated navigation paths for escapees and rescuers wearing self-contained breathing apparatus. While protecting escapees, it improves the accessibility of the scene for rescuers, enabling them to pass through areas with smoke but no fire, thus improving rescue efficiency. It can also automatically adjust the user's personalized navigation route in real time based on fire alarm information from the fire monitoring controller and map marking information from rescuers, making the escape route more efficient and reasonable.

[0115] The preferred implementation process for the long-term static automatic marking function is as follows: Figure 5 As shown, it includes the following steps:

[0116] S21. The user's terminal device automatically connects to the wireless module of the emergency light fixture via Bluetooth or Starlight, and the connected emergency light fixture sends the coordinate information and fixture ID of the emergency light fixture to the user's terminal device.

[0117] S22. Calculate the distances d1, d2, and d3 between the user's terminal device and the three emergency lights using the RSSI values. Calculate the coordinates of the user's terminal device using the three-point positioning method based on the light IDs of the three emergency lights.

Figure 8 ;

[0130] In the absence of signal, inertial navigation is used: When the terminal device cannot establish a communication connection with at least three emergency lights and the basic conditions for wireless positioning are not met, the inertial navigation algorithm will be used based on the data from the accelerometer and electronic gyroscope in the device terminal to calculate and display the current position change of the user terminal device until the terminal device re-establishes a wireless connection with at least three emergency lights.

[0140] S39. The terminal device parses the "message information" data packet to obtain the message information;

[0141] The messages can be in text or audio format; users can repeatedly view or listen to the messages on their devices, improving the success rate of information retrieval; the fire command center can also view message records through the cloud platform to understand the situation on site.

[0142] Preferably, the implementation process for recording evacuation drills is as follows: Figure 10 As shown, it includes the following steps:

[0143] S41. The user's terminal device automatically connects to the wireless module of the emergency light fixture via Bluetooth or StarFlash, and the connected emergency light fixture sends the coordinate information and fixture ID of the emergency light fixture to the user's terminal device.

[0147] S45. The emergency lighting controller parses the "user location" data packet and synchronizes the parsed data to the cloud platform module for storage;

[0148] When playback is needed, simply parse the location data packets at the emergency lighting controller and mark the locations of all users in chronological order to construct a record of the changes in the positions of all personnel during the escape over time. The evacuation drill recording function allows users to conduct evacuation drills in realistic evacuation scenarios. The movement trajectory of each user carrying a terminal device will be recorded in the emergency lighting controller over time. After the evacuation is completed, the trajectory can be queried to review the accident and optimize the evacuation plan. The evacuation drill recording function can obtain more valuable and realistic data than existing computer simulation drills, and can also enhance people's fire safety awareness and increase their escape experience.
