[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Example

[0021] Please refer to Figure 1The present invention provides a glasses system with a guiding function for chemical fires. The protective indicating glasses are provided with a central control system and a wind direction identifier, a regional sound and light alarm, a flame detector and a flame identification video monitor connected to the central control system. The central control system controls the wind direction identifier, the regional sound and light alarm, the flame detector and the flame identification video monitor. The central control system includes a logic judgment control system and a DCS data analysis unidirectional processor and a GDS data analysis single processor. The DCS data analysis unidirectional processor is connected to the DCS control system, and the GDS data analysis single processor is connected to the GDS control system; wherein the GDS is a distributed control system, the wind direction identifier is used to monitor the wind direction information at the fire scene, the regional sound and light alarm is used to emit sound and light signals, and the flame detector is used to detect the flame at the fire scene. The flame recognition video monitor is used to monitor the flame situation at the fire scene in real time and identify it. The logic judgment control system is used to determine the dangerous situation and analyze the reasonable escape route based on the collected information. The GDS data analysis single processor and other sources of real-time data, including the size of the fire, the direction of spread, the smoke concentration, the wind direction and speed, the distribution of dangerous gases, the distribution of personnel, the structure of the building, etc., comprehensively understand the situation on the scene and provide a rich information basis for the analysis of the escape route. It mainly relies on AI algorithm (artificial intelligence algorithm) and Dijkstra algorithm (Dijkstra algorithm, which is a typical shortest path algorithm used to calculate the shortest path from a specific vertex in a graph or network to all other vertices) optimization, considering factors such as distance, obstacles, personnel traffic capacity, and the location of the safe exit to calculate the optimal escape route.

[0022] Mainly rely on dynamic updates: The logic judgment control system should be able to monitor changes in the fire scene in real time and dynamically update the escape route based on the new data. If the fire suddenly changes direction, a new dangerous area appears, or the original passage is blocked, the system should immediately recalculate the escape route and convey the updated information to personnel in a timely manner.

[0023] Mainly rely on simulation verification: During the system development and testing stage, by building a virtual model of the chemical plant, a large number of fire simulation experiments are carried out to verify the rationality of the analyzed escape routes. According to the simulation results, the system is adjusted and optimized to improve its reliability in practical applications.

[0024] The wind direction identifier integrates the methods of identifying wind direction and wind force into one, and is divided into mechanical mode: a cup anemometer is used, which consists of three or four conical or hemispherical hollow cup shells. When the wind blows from different directions, the cups will rotate at different speeds, and the wind direction is determined by measuring the rotation speed and direction of the cups; another electronic mode: an ultrasonic wind direction sensor, which calculates the wind direction by emitting ultrasonic waves in different directions and measuring the time difference of ultrasonic waves propagating in the air; synchronous analysis of mechanical and electronic modes ensures the optimal data of environmental wind direction.

[0025] The wind direction identifier should be resistant to high temperatures, dust, and water, ensuring that it can still work normally under extreme conditions; use high-temperature resistant materials to manufacture key components, such as the sensor housing is made of high-temperature resistant alloys, tungsten-molybdenum alloys or ceramic materials can be selected, which can withstand high temperatures without deformation or damage. The internal electronic components should be selected to be able to work stably in high-temperature environments, and high-temperature grade integrated circuits and resistors and capacitors should be used. An effective heat dissipation design should be adopted, and heat sinks, ventilation holes or liquid cooling should be added to prevent equipment failure due to overheating. Dust-proof features: install dust filters or filters to prevent dust from entering the sensor. , while not affecting air circulation and wind direction detection, the interfaces and gaps of the equipment are sealed to prevent dust from penetrating through the gaps, and a surface coating with a self-cleaning function is used to prevent dust from adhering, or the dust is automatically shaken off by vibration, etc. Waterproof characteristics: The shell can be waterproof and sealed according to the on-site environment to achieve a higher waterproof level, such as IP67 or higher. All interfaces and connections use waterproof plugs, sealing rings and other waterproof measures to ensure that moisture cannot enter the internal circuit. The internal circuit adopts moisture-proof treatment, such as applying moisture-proof coating or using moisture-proof packaging materials to prevent water vapor from eroding electronic components. In addition, in order to further improve the reliability of the wind direction identifier under extreme conditions, redundant design is added, and backup sensors or backup circuits can be automatically switched when the main component fails to ensure uninterrupted operation; strict environmental tests are carried out, including high temperature aging test, dust and water test, vibration shock test, etc., to verify the performance and reliability of the equipment in harsh environments. Equipped with a fault monitoring and alarm system, once the equipment is abnormal, it can send an alarm to the central control system in time so that corresponding measures can be taken.

[0026] The wind direction identifier should be able to continuously monitor wind direction information in real time and promptly feed back the latest data to the central control system so that escape strategies and instructions can be adjusted in a timely manner.

[0027] The regional sound and light alarm has a variety of preset alarm modes, which can send out sound and light signals with different frequency, timbre and brightness combinations according to the severity of the fire and the different danger zones.

[0028] A positioning module is installed inside the protective indicator glasses. The positioning module adopts personal beacon technology to ensure the accuracy and stability of positioning. For example, in the early stage of a fire, a relatively mild but continuous sound and light alarm is issued to alert people. When the fire spreads or the danger increases, it switches to a strong, rapid and eye-catching sound and light signal to strongly warn people to take quick escape action.

[0029] The protective indicator glasses have a protective device that can effectively block the high temperature, smoke and harmful gases generated by the fire from damaging the wearer's eyes; the protective device includes lenses made of high-temperature resistant materials, a sealed frame structure and a device for filtering harmful gases; the protective indicator glasses have a built-in indication module that can receive escape route indication information sent by the central control system and display it to the wearer in an intuitive manner; the indication module can provide instructions to the wearer through projection displays on the lenses, flashing indicator lights or voice prompts; the protective indicator glasses have a communication function and can maintain real-time communication with the central control system, and feed back the wearer's location and status information to the central control system; the communication function uses wireless beacon technology, and the individual use protective indicator glasses are designed to be lightweight and comfortable, which is convenient for the wearer to use for a long time in an emergency.

[0030] The flame recognition video monitor is a camera with high resolution and wide-angle field of view installed at the site of the chemical plant. It obtains real-time video images to cover a larger monitoring area. It performs pre-processing operations such as denoising, enhancement and graying on the collected images to improve image quality and reduce interference, and highlight the characteristics of the flame. It extracts flame-related features from the pre-processed images, including color, shape, texture, flickering frequency, etc., among which flames usually have unique color characteristics of red, orange and yellow combination, as well as irregular dynamic shapes and certain flickering frequencies. It uses machine learning or deep learning algorithms, such as support vector machines, decision trees, convolutional neural networks, etc., to perform pattern recognition on the extracted features. After training on a large number of images containing flames and non-flames, the model can determine whether there is a flame in the image based on the extracted features, and estimate the type, size and location of the flame. The above processing and recognition process is continuously performed on newly collected images to realize real-time monitoring of the flame situation at the fire scene. When a flame is detected, the system issues an alarm and transmits relevant information to the central control system. The monitored flame data is analyzed and recorded, covering the time, location, development trend, etc. of the flame, to provide data support for subsequent accident investigation and emergency response.

[0031] Access to the DCS control system is used to obtain relevant process parameters; the DCS control system is used for high-performance data acquisition and conversion system: it can quickly and accurately collect a large amount of process parameter data from the DCS control system and convert it into a format that can be recognized and processed by the central control system. Intelligent data analysis engine: using machine learning and data mining technology, in-depth analysis of the collected process parameter data is carried out to extract valuable information and potential trends. Real-time data processing and monitoring platform: with powerful real-time processing capabilities, it can process and monitor the incoming process parameter data in real time and detect abnormal situations in time. Distributed data storage system: used to store a large amount of process parameter historical data, supporting fast retrieval and query for data analysis and traceability. Data fusion and integration system: it can fuse and integrate process parameters from the DCS control system with data from other monitoring systems to provide more comprehensive and accurate information. Risk assessment and early warning module: based on process parameter data and preset risk models, it assesses potential risks and issues an alarm in time when the early warning threshold is reached. Visual display and interactive interface: the process parameter data and analysis results are presented to operators in an intuitive and clear way, supporting real-time interaction and operation.

[0032] The GDS control system is used to obtain gas detection information; when the GDS control system is connected, it will first continue to receive real-time data from various gas sensors, including detailed information such as the concentration value, detection location, and detection time of different types of gases. The system will preliminarily screen and organize these raw data to remove obvious abnormal values ​​and noise interference. Then, the preliminarily processed data will be compared with the preset safety thresholds. These thresholds are set according to relevant chemical safety standards and regulations, as well as the characteristics of specific chemical equipment and the hazardous properties of the gases involved. For the concentration data of a single gas, if it exceeds the corresponding safety threshold, the system will immediately mark it as a dangerous state and trigger the corresponding alarm mechanism. However, the analysis of the GDS control system is not limited to the concentration judgment of a single gas. It will also comprehensively consider the interaction and synergistic effects of multiple gases. For example, some gases may cause more serious harm when mixed, or the presence of one gas may affect the detection accuracy of another gas. The system uses complex algorithms and models to evaluate the potential dangers of these gas combinations. At the same time, the GDS control system will analyze the changing trend of gas concentrations. If the concentration of a certain gas rises rapidly in a short period of time, even if the current concentration has not yet reached the safety threshold, the system will regard it as a potential danger signal, because this may indicate that the dangerous situation is rapidly deteriorating. In addition, the system will further optimize the judgment based on the operating status of the chemical plant, the process flow, and environmental factors (such as temperature, pressure, etc.). For example, under specific production links or process conditions, the appearance or concentration changes of certain gases may have special significance. Through the above multi-dimensional and comprehensive data analysis, the GDS control system can accurately determine whether the gas conditions in the chemical plant are safe, and make corresponding decisions in a timely manner, such as sounding an alarm, starting ventilation equipment, and notifying the central control system to adjust the escape route, etc., to ensure the safety of personnel and the safe operation of the chemical plant.

[0033] The present invention is simple to operate, convenient to use, and suitable for comprehensive promotion and application. Although the embodiments of the present invention have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
