Description

Technical Field

[0001] The present application relates to the field of monitoring and early warning technology, and more particularly to an intelligent monitoring and alarm system and method for escape routes. Background Art

[0002] Take tunnel construction, for example. The geological conditions are complex and prone to sudden geological disasters, making various safety accidents prone to occur during construction. The "Technical Specifications for Highway Engineering Construction Safety" and the "Guidelines for Highway and Waterway Engineering Construction Safety Standardization" specify that escape routes should be provided during tunnel excavation in areas with weak surrounding rock. These escape routes are constructed using φ800mm steel pipes. The escape routes start at the end of the newly constructed secondary lining, no more than 5 meters away from the end. The routes are laid from the lining working face to an appropriate location within 20 meters of the excavation face. The pipes are laid along one side of the initial support toward the tunnel face, with a reserved working rope inside the pipes to facilitate escape, rescue, communication, and the transport of various items.

[0003] In actual applications, existing escape routes still have shortcomings such as low intelligence and poor accessibility to accident rescue, which are mainly reflected in the following aspects: (1) Once a tunnel collapse or door collapse accident occurs during construction, the communication line between the construction site and the outside world is often cut off due to the collapse or collapse accident, resulting in the backstage and relevant rescue personnel being unable to clearly understand the type of accident and related specific circumstances; (2) When an accident occurs, it is impossible to issue an alarm or warning in time, resulting in the inability of people on the construction site to enter the escape passage in the first place; and the escape passage in the existing technology cannot effectively count the number and distribution of people entering the escape passage; The existence of the above problems increases the difficulty of rescue at the scene of tunnel construction accidents and reduces the survival rate of on-site construction workers. Therefore, it is of great significance to upgrade the intelligent and digital transformation of escape routes. Summary of the Invention

[0004] In view of the fact that the intelligence level of tunnel construction escape passages in the existing technology is generally low, which makes it difficult to make accurate warnings of accidents, and after the accident occurs, it is difficult for the outside world to promptly determine the cause of the accident and the situation of the personnel on the scene, which is not conducive to accident rescue. The first purpose of this application is to provide an intelligent monitoring and alarm system for escape passages, which can monitor the relevant parameters in the tunnel and then make analysis and warnings of accidents. When an accident occurs, it can promptly guide on-site construction personnel into the escape passage and send the accident scene environment and personnel situation data to the background, which is conducive to the development of accident rescue and investigation work and reduces the casualty rate of accident personnel. Based on the above-mentioned intelligent monitoring and alarm system, the second purpose of this application also proposes an intelligent monitoring and alarm method for escape passages. The specific scheme is as follows: An intelligent monitoring and alarm system for escape routes, comprising: The recognition and warning module is configured to collect and obtain various monitoring data and, based on a set recognition model, analyze and output accident warning signals of different levels; The on-site recording module includes a data storage component and a personnel status acquisition component, configured to continuously collect and store, and / or collect and store ID information and location information of each person on the construction site in response to the accident warning signal; An accident alarm module is configured to receive the accident warning signal and output corresponding on-site sound and light prompt signals and monitoring background warning signals in response; A communication module, comprising at least two data communication links, configured to realize communication connection between construction site equipment and monitoring background, receive the accident warning signal and construction site personnel status information and output it to the monitoring background; A control module configured to coordinate and control the working status of each functional module; The personnel status acquisition component includes: An on-site personnel monitoring unit includes an image recognition submodule connected to the on-site image acquisition device for identifying personnel ID information and positions in an image, and for identifying and outputting first personnel ID information and first position information; The channel personnel monitoring unit includes a radio frequency tag worn by on-site personnel and multiple radio frequency identifiers set in the escape channel. In response to a specific level of accident warning signal, it identifies and outputs the second person ID information and second location information entering the escape channel.

[0005] Through the above technical solution, the collection of various monitoring data and the combination of the set algorithm model can provide early warning or type identification of accidents. As a result, the accident warning module can output corresponding audio and visual prompt signals in advance, prompting on-site construction personnel to take appropriate risk avoidance actions. By using the image acquisition device installed at the construction site and combining it with the image recognition algorithm to identify the ID information and location of each person, the status of each construction personnel at the time of the accident can be known. The radio frequency tags worn by the construction personnel and the radio frequency identifiers installed in the escape route can clearly know the personnel information of the construction personnel entering the escape route and their location information within the escape route. The above solution can provide early warning before the accident occurs, reducing on-site casualties. After the accident occurs, the monitoring background can quickly determine the accident type through the identification and warning module. At the same time, the on-site recording module can immediately determine the distribution of personnel on the construction site, facilitating the rapid and accurate formulation of rescue and disaster relief plans, thereby reducing the accident casualty rate.

[0006] Furthermore, the identification and early warning module includes a monitoring data acquisition component and a monitoring data processing component, wherein: The monitoring data acquisition component includes: A vibration signal detection component, comprising a plurality of vibration detection sensors arranged in escape passages and construction sites, for detecting and outputting vibration detection signals; Sound signal detection components, including multiple sound sensors installed in escape routes and construction sites, for detecting and outputting sound detection signals; A stress detection component, including a resistance strain sensor or an optical fiber strain sensor, is used to detect stress changes at a set location on the construction site and output a stress detection signal; Image acquisition unit, including multiple cameras, used to capture image information of a set area on the construction site and output it; A temperature detection component, comprising a plurality of temperature sensors, for detecting and outputting temperature detection signals; A humidity detection component, comprising a plurality of humidity sensors, for detecting and outputting a humidity detection signal; The monitoring data processing component includes: The data conversion component is connected to the monitoring data acquisition component and is used to convert each detection signal into a set type of data format and output it; A data processing unit, having a built-in recognition model for predicting or identifying the type, level, and location of an accident based on each detection signal, receives each converted detection signal data and generates accident warning signals of different levels based on the recognition model; The result output component is configured to be data-connected with the on-site recording module, the accident warning module and the communication module, receives the accident warning signals of different levels and outputs them to the setting module after data conversion.

The sound and light prompt submodule set up on site can quickly guide and prompt on-site personnel to evacuate and avoid danger when an accident occurs, thereby reducing the probability of casualties after the accident.

It includes multiple communication relay nodes arranged at set intervals in the escape channel, which are used to transmit the data in the data storage component to the monitoring background via the Bluetooth communication network.

[0013] Through the above technical solution, different levels of accident warning signals correspond to different communication links or their combinations, which can ensure that after an accident occurs, various environmental status information data and personnel status information data of the construction site can be transmitted to the monitoring background in a timely and stable manner, so that external staff can know the detailed situation of the construction site and have an intuitive and clear understanding of information such as the type of accident, which is convenient for formulating risk elimination and rescue plans and reducing the probability of casualties caused by accidents; in addition, in the above solution, different types of communication links are responsible for the transmission of different types of data. Communication links with smaller communication bandwidth and easily affected by accidents are mainly responsible for transmitting short and necessary data, while communication links with communication bandwidth that is not easily interfered with, such as optical fiber communication sub-modules, are used to transmit detailed and large amounts of data, effectively ensuring communication quality.

[0014] Furthermore, the communication control submodule also includes or is connected to: A data importance level determination unit is configured to be connected to the data of the identification and warning module, and to classify and mark the importance level of each detection signal data according to the correlation between each detection signal data and the accident type and accident location; A data size detection unit is configured to be data-connected to the field recording module and is used to calculate and mark the data volume of each detection signal data, personnel ID information and location information in the data storage component; a communication duration estimating unit configured to be data-connected to the communication module, obtain the data communication status of each communication link, and generate the data transmission duration required for each communication link for each data to be transmitted based on the data transmission bandwidth of each communication link and the data volume of each data to be transmitted; The communication link allocation unit selects the corresponding communication link for each data to be transmitted based on the importance level, data volume and data transmission time required for each communication link, combined with the reliability evaluation results of each communication link and based on a set algorithm.

[0015] Through the above technical solution, an appropriate data transmission link can be allocated to each data to be transmitted based on the importance level of the data to be transmitted and the reliability assessment results of the communication link. This can ensure that various detection signal data, personnel ID information and location information data at the construction site can be transmitted to the monitoring background, facilitating the formulation of disaster relief and rescue plans and reducing the casualty rate of accidents.

[0016] Furthermore, the intelligent monitoring and alarm system also includes: The SOS call submodule includes a button trigger component and a voice trigger component set at a set position in the escape passage, which is connected to the communication module signal, detects and outputs an SOS signal to the monitoring background according to the trigger state of the button trigger component or the voice trigger component; The real-time communication submodule includes a microphone and a player, which is used to collect the voice information of people in the escape channel and output it to the monitoring background and play the voice data of the monitoring background; The infrared sensing submodule includes multiple infrared human body detection sensors set at set positions in the escape channel, which are used to detect the number of people in the escape channel and output the escape channel human body detection signal to the monitoring background; The emergency rescue submodule includes a first aid box and a tablet computer arranged on the first aid box, wherein the tablet computer is loaded with first aid instruction video data.

[0017] Through the above technical solution, people who enter the escape channel can send a rescue request to the monitoring background outside the tunnel through the SOS call sub-module. The specific situation of the escape channel and the construction site can be reported to people outside the tunnel using the voice call sub-module, so that relevant personnel can understand the accident situation and the current status of the people. The infrared sensing sub-module can be used to further determine the number of people in the escape channel, and combined with the output results of the channel personnel monitoring unit, the statistical accuracy of the number of trapped people can be improved.

[0018] Furthermore, the intelligent monitoring and alarm system also includes a channel integrity detection module for detecting damage to the escape route, including: a sound determination submodule configured to detect voiceprint data corresponding to a sound source at a set position in the escape passage transmitted to a target position, and determine the extent of damage to the escape passage based on the voiceprint data; and / or The optical fiber determination submodule includes an optical fiber arranged along the length of the escape passage and an optical signal transceiver module, and determines the degree of damage to the escape passage based on the wavelength or phase change of the optical signal in the optical fiber.

[0020] Furthermore, the monitoring and alarm system also includes: Personnel movement monitoring modules are deployed at the construction site and on personnel's personal devices to monitor the location and posture of each person at the construction site. a response speed detection module, connected to the accident warning module and the personnel movement monitoring module, receiving the accident warning signal and starting a timer, analyzing and calculating the position and posture changes of each person on the construction site within a set period of time since the accident warning signal was issued, and outputting a vibration warning signal based on the analysis results; The vibration warning module includes multiple vibrators worn on the personal devices of on-site construction workers.

[0028] Embodiments of the present application are described in detail below, examples of which are illustrated in the accompanying drawings.

[0029] Throughout this specification, reference to the terms "certain embodiments," "one embodiment," "some embodiments," "illustrative embodiments," "examples," "specific examples," or "some examples" means that a specific feature, structure, material, or characteristic described in conjunction with the embodiment or example is included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0030] An intelligent monitoring and alarm system for escape routes, such as Figure 1 As shown, it mainly includes an identification and warning module 100, a scene recording module 200, an accident alarm module 300, a communication module 400 and a control module 600.

[0031] The recognition and warning module 100 is used to collect and obtain various set monitoring data and analyze and output accident warning signals of different levels based on the set recognition model.

[0032] In the embodiment of this application, combined with Figure 2 As shown, the above-mentioned identification and warning module 100 includes a monitoring data acquisition component 110 and a monitoring data processing component 120. Figure 1 As shown, the monitoring data acquisition component 110 mainly includes an image acquisition component 114 , a vibration signal detection component 111 , a sound signal detection component 112 , a stress detection component 113 , a temperature detection component 115 and a humidity detection component 116 .

[0033] The image acquisition component 114 includes multiple cameras for capturing and outputting image information of a set area of ​​the construction site.

[0034] The vibration signal detection component 111 includes a plurality of vibration detection sensors arranged at set intervals in the escape passage and the construction site, and the plurality of vibration detection sensors form a vibration monitoring network for detecting the vibration frequency of the escape passage pipe body, the inner wall of the tunnel and the ground. In the embodiment of the present application, the above-mentioned vibration detection sensor preferably adopts a piezoelectric vibration sensor, which has the characteristics of high precision, high sensitivity and durability. The above-mentioned vibration monitoring network can detect and output vibration detection signals. At the same time, according to the relative position relationship between each vibration detection sensor and the vibration detection signal, it can quickly know the source and attenuation of the vibration, and then infer the type, intensity and location of the accident. The sound signal detection component 112 includes a plurality of sound sensors arranged in the escape passage and the construction site, which are mainly used to detect and output sound detection signals of accidents such as explosions and landslides. The type, intensity and location of the accident can be further determined in conjunction with the vibration detection signal.

[0035] Stress detection element 113 primarily comprises a resistive strain sensor or a fiber optic strain sensor. In the present embodiment, a fiber optic strain sensor is preferably used. The optical fiber is positioned at a specific location within the tunnel, such as a support structure or load-bearing structure, to detect stress changes at a specific location within the construction site and output a stress detection signal. Using such a fiber optic strain sensor can detect even small, continuous deformations at these specific locations, thereby providing early warning of accidents such as collapses.

[0036] Temperature detection element 115 includes multiple temperature sensors for detecting and outputting temperature detection signals. In the embodiments of this application, temperature detection in the tunnel is preferably achieved using a distributed fiber optic temperature measurement system. Humidity detection element 116 includes multiple humidity sensors, located on the inner wall of the tunnel, for detecting and outputting humidity detection signals at the construction site. By monitoring the temperature and humidity at the construction site, it is possible to optimize concrete pouring parameters and, based on changes in on-site temperature and humidity, predict accidents such as water seepage.

[0037] The monitoring data processing component 120 includes a data conversion component 121 , a data processing component 122 and a result output component 123 .

[0038] Because the output data formats of each detection component vary, to facilitate processing, data converter 121 is digitally connected to the signal output terminals of each detection component in monitoring data acquisition assembly 110. It receives the detection signal data and then converts each detection signal into a predetermined data format for output. In practice, data converter 121 primarily includes a filtering and noise reduction module and an A / D conversion module, which converts analog signals into digital signals within a predetermined range.

[0039] The data processing unit 122 is equipped with a recognition model for predicting or identifying the type, level and location of accidents based on various detection signals, receiving the converted detection signal data and generating accident warning signals of different levels based on the recognition model. In the embodiment of the present application, the above-mentioned data processing unit 122 can adopt a single-chip microcomputer or an FPGA module. The recognition model is mainly used to find monitoring data or a combination thereof that matches each accident type, and then output the corresponding accident warning signal. For example, when the stress at the support structure in a certain area is monitored to gradually increase and exceed the set threshold, it can be determined to output a collapse accident warning signal; for example, when the vibration detection signal of a certain area is detected to be consistent with the vibration frequency caused by the collapse, it can be determined that a collapse accident has occurred in the area. At the same time, the amplitude and frequency of the sound detection signal can be retrieved to further determine the type of accident, and finally a collapse accident warning signal is output.

[0040] The result output component 123 is configured to be data-connected with the on-site recording module 200, the accident alarm module 300 and the communication module 400, and receives the recognition results output by the single-chip microcomputer or FPGA module, that is, accident warning signals of different levels, and then outputs them to the setting function module after data conversion. For example, the output accident warning signal is directly output to the sound and light prompt sub-module in the accident alarm module 300 after DA conversion and isolation amplification, or a corresponding control signal is output according to the level of the accident warning signal. For example, when the accident level requires on-site personnel to evacuate immediately, the above-mentioned control signal controls the activation of certain functional units in the on-site recording module 200, or activates certain detection components set up at the construction site.

[0041] The above technical solution can provide accurate early warning of accidents based on multiple monitoring data, or accurately know the type, intensity and location of the accident after it occurs, which is helpful for accident classification and subsequent investigation of the cause of the accident, and also helps in the formulation of relevant risk elimination and remediation plans.

[0042] In order to record the personnel and environmental conditions at the construction site and facilitate early warning analysis and subsequent analysis of the cause of the accident, in the embodiment of the present application, the on-site recording module 200 includes a data storage component 210, a personnel status acquisition component 220, and an environmental status acquisition component 230, which are used to continuously collect and store and / or collect and store construction site environmental status data and personnel status data in response to the accident warning signal.

[0043] The above-mentioned environmental status data includes various environmental parameters of the construction site, such as ambient temperature and humidity data, tunnel wall vibration data, stress change data at specific locations, etc. The personnel status data includes the ID information and distribution location information of each personnel at the construction site.

[0044] In detail, the personnel status acquisition component 220 includes an on-site personnel monitoring unit 221 and a channel personnel monitoring unit 222 .

[0045] The on-site personnel monitoring unit 221 includes an image recognition submodule, data-connected to an on-site image acquisition device, such as an on-site surveillance camera, for identifying personnel ID information and their location within an image. This image recognition submodule is an image recognition program module deployed within the data processor at the construction site and the monitoring backend 500 server. It is used to acquire on-site surveillance images captured by the surveillance camera and identify and output first personnel ID information and first location information. The first personnel ID information includes the personnel's name and number, and the first location information refers to the personnel's location coordinates within the construction site.

[0046] The channel personnel monitoring unit 222 includes a radio frequency tag worn by on-site personnel and multiple radio frequency identifiers set in the escape channel. The radio frequency tag can be an RFID tag, and the corresponding radio frequency identifier is an RFID identifier. Considering that the diameter of the escape channel is usually 80 cm, in order to reduce unnecessary interference, the recognition range of the radio frequency identifier is set to no more than 50 cm, so that when a person enters the escape channel, the RFID tag he wears can be automatically sensed. In the embodiment of the present application, the number of the radio frequency identifiers is multiple and they are arranged along the length of the escape channel, so that the position of each person in the escape channel can be continuously collected and obtained, and the radio frequency identifier is connected to a corresponding controller, such as a single-chip microcomputer control module, which is activated in response to a specific level of accident warning signal, and then identifies and outputs the second person ID information and second position information of the person entering the escape channel. The second person ID information includes the person's name and number, and the second position information refers to the position coordinates of each person in the escape channel.

[0047] In actual applications, the monitoring background 500 can know whether there are people who have not evacuated the accident scene in time, the current approximate location of the people who have not evacuated, etc. by comparing the first person ID information and the second person ID information, which is convenient for subsequent rescue and disaster relief work.

[0048] The environmental state acquisition component 230 is configured to be data-connected to the monitoring data acquisition component 110, and is used to acquire and store the detection signals output by each detection component, such as the stress detection component 113, the temperature monitoring component, etc., and store them in association with the location coordinates of the detection components.

[0049] The data storage component 210 includes a first data storage and a second data storage that are control-connected to the control module 600 .

[0050] The first data storage device is configured to be data-connected to the personnel status acquisition component 220, the environmental status acquisition component 230 and the communication module 400, and is used to temporarily store the detection signal data collected within a set time period and its associated position coordinates, personnel ID information and position information. The data stored in the above-mentioned first data storage device is sent in real time to the monitoring background 500 via the communication module 400 for analysis or storage.

[0051] The second data storage device is configured with a specific data compression algorithm and is data-connected to the first data storage device. It is used to obtain and compress the detection signal data collected during each time period, along with its associated location coordinates, personnel ID information, and location information. This second data storage device is used to store data collected over a longer period of time and store it in an on-site storage device, such as a data storage hard disk. This prevents the loss of monitoring data and allows the relevant monitoring data to be retrieved even after a failure of the communication module 400.

[0052] In the embodiment of the present application, the accident alarm module 300 is configured to be data-connected with the identification and warning module 100, and is configured to receive the accident warning signal, and respond to and output the corresponding on-site sound and light prompt signal and the monitoring background 500 warning signal.

[0053] Detailed, such as Figure 1 As shown, the accident alarm module 300 includes an on-site alarm component 310 and a remote alarm component 320. The on-site alarm component 310 mainly includes an audio and video category storage submodule, an escape route storage submodule, an audio and video control submodule, an intelligent escape route generation submodule, an escape guidance control submodule, an audio and video prompt submodule, and a route indication submodule.

[0054] The sound and light category storage submodule is configured to store the sound and light categories corresponding to each level of accident warning signals in an associated manner. For example, if the green LED light on the scene is on, it means everything is normal; if the yellow LED light is on, it means there is a potential accident hazard and it needs to be carefully checked; if the red LED light is on, it means a serious accident has occurred and emergency evacuation is required. The above sound and light categories correspond to different control codes, which are stored as accident codes in the single-chip computer control module. The escape path storage submodule is configured to store the escape paths and precautions corresponding to each level of accident warning signals in an associated manner. For example, if there is a serious landslide risk above the first entrance of the escape passage, the escape path is changed to the path from the construction site to the second entrance of the escape passage.

[0055] The sound and light control submodule is data-connected to the identification and warning module 100 and the sound and light category storage submodule. It receives the accident warning signal, analyzes its warning level, and outputs a corresponding sound and light control signal. In practical applications, the sound and light control submodule can be integrated into the system control module 600. The sound and light prompt submodule includes multiple LED lights of different colors and a siren connected to the sound and light control submodule. In response to the sound and light control signal, it outputs sound and light prompt information, including lights of different colors and alarm sounds of different frequencies.

[0056] The intelligent escape path generation submodule is configured to be data-connected to the identification and warning module 100 and the on-site recording module 200, receive accident warning signals to determine the accident level, obtain and generate the optimal escape path corresponding to each person based on the ID information and location information of the construction site personnel, so that on-site personnel can enter the escape passage in the fastest and safest way. The escape guidance control submodule is data-connected to the intelligent escape path generation submodule, receives the optimal escape path data and generates guidance control signals. The path indication submodule includes multiple projection lights and a voice player, receives the guidance control signals output by the escape guidance control submodule, projects guidance signs in a set area on the construction site, and plays voice prompt information, such as projecting arrows and other signs on the ground, to guide on-site personnel to enter the escape passage as quickly as possible according to the set path.

[0057] The remote alarm component 320 includes a terminal display device connected to the identification and warning module 100 via the communication module 400, such as a computer monitor in the monitoring room and supporting audio equipment, etc., to prompt the staff in the monitoring room.

[0058] The communication module 400 includes at least two data communication links 440 , which are configured to realize a communication connection between the construction site equipment and the monitoring background 500 , receive the accident warning signal and the construction site personnel status information and output them to the monitoring background 500 .

[0059] Detailed, such as Figure 3 As shown, the communication module 400 includes a communication link 440 detection submodule 410, a communication link 440 selection control submodule 420, a communication control submodule 430, and multiple communication links 440. The communication link 440 detection submodule 410 is configured to detect the data communication status of each communication link 440 and output a reliability assessment result of the communication link 440. In actual applications, communication parameters such as delay and data bandwidth can be obtained by sending test data to the monitoring background 500 and receiving feedback data from the monitoring background 500. The communication link 440 selection control submodule 420 is configured to associate and store accident warning signals of different levels, communication link 440 categories corresponding to different reliability assessment results, or a combination thereof. The communication control submodule 430 is configured to be signal-connected with the communication link 440 detection submodule 410 and the identification and warning module 100, and based on the communication link 440, selects the stored association relationship in the control submodule 420, and autonomously or under control selects a set category of communication link 440 or a combination of different categories of communication links 440 to realize the communication connection between the construction site equipment and the monitoring background 500.

[0060] In the embodiment of the present application, the communication link 440 includes a 4G / 5G communication submodule 441, a fiber optic communication submodule 442, and a Bluetooth networking submodule 443. The 4G / 5G communication submodule 441 is configured to be controlled and connected with the communication control submodule 430, receive the accident warning signal output by the identification and warning module 100 and the personnel ID information and location information output by the personnel status acquisition component 220, and send them to the monitoring background 500. The above-mentioned communication control submodule 430 can be directly separated and set from the control module 600. The fiber optic communication submodule 442 includes a signal modulation unit and a transmission optical fiber. The main body of the transmission optical fiber is configured in the escape passage. The signal modulation unit is control-connected to the communication control submodule 430 and data-connected to the field recording module 200, and is used to obtain and transmit the detection signal data collected in each time period and its associated location coordinates, personnel ID information and location information to the monitoring background 500. The above-mentioned signal modulation unit can be directly implemented by multiplexing the relevant data processing components in the control module 600.

[0061] The Bluetooth networking submodule 443 is connected to the communication control submodule 430 and is data-connected to the on-site recording module 200. It includes multiple communication relay nodes spaced at predetermined intervals within the escape passage, and is used to transmit data from the data storage component 210 to the monitoring backend 500 via the Bluetooth communication network. For example, a Bluetooth Mesh networking module is used to achieve data transmission.

[0062] To ensure that important data is transmitted first, in this application, the communication control submodule 430 also includes or is connected to a data importance level determination unit, a data size detection unit, a communication duration estimation unit, and a communication link 440 allocation unit.

[0063] The data importance level determination unit is configured to be data-connected to the identification and warning module 100, and to classify and mark each detection signal data according to its correlation with the accident type and the accident location. If the accident type is determined to be a door collapse accident, then the relevant monitoring data will focus on retaining the monitoring data related to the above-mentioned door collapse accident, such as stress detection signal data, sound detection signal data, image data, etc. at the collapse location.

[0064] The data size detection unit is configured to be data-connected to the field recording module 200 and is used to calculate and mark the data volume of each item of detection signal data, personnel ID information, and location information in the data storage component 210. The communication duration estimation unit is configured to be data-connected to the communication module 400 and obtain the data communication status of each communication link 440. Based on the data transmission bandwidth of each communication link 440 and the data volume of each data to be transmitted, it generates the data transmission duration required for each communication link 440 for each data to be transmitted. The communication link 440 allocation unit selects the corresponding communication link 440 for each data to be transmitted based on the importance level, data volume, and data transmission duration required for each communication link 440, combined with the reliability assessment results of each communication link 440, and based on a predetermined algorithm. For example, the unit normalizes the four reference data items (importance level, data volume, data transmission duration, and reliability assessment results) and represents each reference data item with a numerical value. The unit then performs a weighted fusion process on each reference data item to determine the corresponding communication link 440.

[0065] The above technical solution can allocate an appropriate data transmission link to each data to be transmitted based on the importance level of the data to be transmitted and the reliability evaluation results of the communication link 440, thereby ensuring that various detection signal data, personnel ID information and location information data at the construction site can be transmitted to the monitoring background 500, facilitating the formulation of disaster relief and rescue plans and reducing the casualty rate of accidents.

[0066] The intelligent monitoring and alarm system of the present application also includes an SOS call submodule 700, a real-time communication submodule, an infrared sensor submodule, and an emergency rescue submodule, all located in the escape passage. The SOS call submodule 700 includes a key trigger component and a voice trigger component located at a predetermined position within the escape passage. The SOS call submodule 700 is signal-connected to the optical fiber communication submodule 442 or the Bluetooth networking submodule 443 in the communication module 400, and detects and outputs an SOS signal to the monitoring backend 500 based on the trigger status of the key trigger component or the voice trigger component. The real-time communication submodule includes a microphone and a player, which are used to collect voice information from people in the escape passage and output it to the monitoring backend 500 via the optical fiber communication submodule 442 or the Bluetooth networking submodule 443. The real-time communication submodule also receives and plays voice data from the monitoring backend 500.

[0067] The infrared sensing submodule includes multiple infrared human detection sensors installed at designated locations in the escape passage, which are used to detect the number of people in the escape passage and output a human detection signal in the escape passage to the monitoring backend 500. The emergency rescue submodule includes a first aid kit and a tablet computer installed on the first aid kit, which is loaded with first aid instruction video data.

[0068] In the embodiment of the present application, the core of the control module 600 is a single-chip control module, which is used to receive and process various monitoring data, and output corresponding control signals according to the built-in algorithm and control program to control the action and status of each functional module.

[0069] In order to ensure the integrity of the escape channel and facilitate the evacuation of people therein through the escape channel, the intelligent monitoring alarm system described in the present application further includes a channel integrity detection module for detecting damage to the escape channel, mainly including a sound judgment submodule and / or an optical fiber judgment submodule.

[0070] Because the escape tunnel is constructed from multiple pipe sections, any breakage at a pipe joint will alter the sound transmitted along the tunnel. Therefore, the sound determination submodule is data-connected to the control module 600 and configured to detect and obtain soundprint data corresponding to the transmission of a sound source at a set location within the escape tunnel to a target location. Based on the algorithm built into the control module 600 and the soundprint data, the control module 600 determines the extent of damage to the escape tunnel. For example, if the sound from the sound source cannot be transmitted through the escape tunnel, it indicates a break somewhere within the escape tunnel. The sound source can be configured as a striking device, such as a motor-driven hammer, for striking the tunnel wall. The fiber determination submodule includes an optical fiber arranged along the length of the escape tunnel and an optical signal transceiver module. It determines the extent of damage to the escape tunnel based on wavelength or phase changes of the optical signal in the optical fiber, such as monitoring for deformation or breakage of the tunnel. This technical solution can assess the damage status of the escape tunnel, facilitating the evacuation and rescue of trapped personnel.

[0071] When an accident warning signal is issued, the construction site environment may prevent construction workers from receiving the evacuation signal immediately. Therefore, the optimized monitoring and alarm system also includes: a personnel movement monitoring module, a response speed detection module, and a vibration warning module. The personnel movement monitoring module is deployed at the construction site and in the personal devices of each personnel to monitor the position and posture of each personnel at the construction site. Similar to the individual positioning devices used by firefighters in the prior art, the personnel movement monitoring module includes a positioning unit, a wireless receiving terminal, and a personnel positioning monitoring platform. The positioning unit is configured to monitor the motion parameter data of each personnel's displacement, direction angle, height, and inclination in real time through an inertial navigation module, and transmit the data to the personnel positioning monitoring platform via the wireless receiving terminal. The wireless receiving terminal is configured to receive and store the wireless data transmitted by the positioning unit, perform preliminary analysis, and output it to the personnel positioning monitoring platform. Based on the received motion parameter data, the personnel positioning monitoring platform integrates and outputs the position, motion trajectory, and posture data of each personnel at the construction site in real time.

[0072] The response speed detection module is connected to the accident warning module and the personnel movement monitoring module signals, receives the accident warning signal and starts timing, analyzes and calculates the position and posture changes of each person on the construction site within a set period of time after the accident warning signal is issued, and outputs a vibration warning signal based on the analysis results. The vibration warning module includes a plurality of vibrators worn on the personal devices of on-site construction personnel. The vibrators are connected to the control module via wireless signal control, receive and output a vibration action of a set frequency in response to the vibration warning signal. The above-mentioned vibrator includes a vibration motor, an independent power supply and a wireless communication control template. Based on the above scheme, when the on-site construction personnel respond too slowly after the accident warning is issued, a vibration alarm for individuals can be output to remind the personnel on the construction site to evacuate to the escape route as soon as possible.

[0073] Based on the above-mentioned intelligent monitoring and alarm system for escape passages, the embodiment of the present application also discloses an intelligent monitoring and alarm method for escape passages, such as Figure 4 As shown, it mainly includes the following steps: S100, establishing and storing an accident identification model for reflecting the association between each accident type and each monitoring data or a combination thereof; S200, collecting and acquiring various monitoring data and outputting accident warning signals of different levels based on the accident identification model; S300, acquiring a scene image and identifying and outputting first person ID information and first location information based on an image recognition algorithm; S400, collecting and storing construction site environmental status data; S500, in response to a specific level of accident warning signal: S510, outputting corresponding on-site sound and light prompt signals and monitoring background warning signals through the accident alarm module; S520, identifying and outputting the ID information and second location information of a second person who has entered the escape passage through a radio frequency identifier configured in the escape passage and a radio frequency tag on the person; S530, detect the data communication status of each communication link in the communication module, output the communication link reliability assessment result, select the corresponding communication link category or its combination to output various monitoring data, personnel ID information and location to the monitoring background in detail.

[0074] Through the above-mentioned intelligent monitoring and alarm method for escape channels, an early warning can be issued before an accident occurs and the personnel and environmental status data of the construction site can be recorded at the same time, which is convenient for the formulation of subsequent risk elimination and rescue plans. In addition, through on-site accident early warning, construction personnel can be prompted to enter the escape channel in advance. During this process, the number of construction personnel entering the escape channel will be counted, and ultimately the accurate acquisition of personnel status information can be achieved.

[0075] In order to improve the risk avoidance efficiency of workers on the construction site and reduce the casualty rate, the method described in this application also includes: S110, associating and storing the escape routes and precautions corresponding to the accident warning signals of each level; S541, receiving the accident warning signal and determining the accident level, obtaining and matching the optimal escape path corresponding to each person based on the first person ID information and the first location information; S542: Receive the optimal escape route and generate a guidance control signal, controlling the route indication submodule to project a guidance sign and play a voice prompt message in a set area at the construction site.

[0076] The above solution allows personnel at the construction site to evacuate to the escape passage along the best avoidance route, thereby reducing the probability of casualties.

[0077] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
