[0044] Other features and advantages of the present invention will be described in the following specification, and, in part, will be obvious from the specification, or will be understood by implementing the present invention. The objectives and other advantages of the present invention can be achieved and obtained by the structures specifically pointed out in the written specification and the drawings.

[0045] The technical solutions of the present invention will be further described in detail below through the drawings and embodiments. Description of the Drawings

In the drawings:

[0049] Figure 3 is a block diagram of a dust filtering device according to an embodiment of the present invention. Detailed Embodiments

[0050] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present invention, and are not intended to limit the present invention.

[0051] As Figure 1 - Figure 2 shown, an embodiment of the present invention provides an intelligent safety explosion-proof system, including: a sealed container, and a dust filtering device, a temperature control device, a moisture control device, and a protective gas control device disposed within the sealed container; wherein,

[0052] The dust filtering device is used to monitor the dust concentration within the sealed container, and when it is determined that the dust concentration is greater than a preset dust concentration threshold, perform dust filtering processing;

[0053] The temperature control device is used to monitor the temperature within the sealed container, and when it is determined that the temperature is not within a preset temperature range, perform temperature control processing;

[0054] The moisture control device is used to monitor the moisture content within the sealed container, and when it is determined that the moisture content is not within a preset moisture content range, perform moisture control processing;

[0055] The protective gas control device is used to monitor the flow rate and pressure of the protective gas within the sealed container, and when it is determined that the flow rate is not within a preset flow rate range and / or the pressure is not within a preset pressure range, perform protective gas control processing.

[0056] The working principle of the above technical solution: The dust filtering device continuously monitors the dust concentration within the sealed container. When the detected dust concentration exceeds the preset safety threshold, it automatically starts the dust filtering process, such as capturing dust particles in the air through a filter to reduce the risk of forming an explosive dust cloud. The temperature control device monitors the temperature within the sealed container to ensure it is within a safe operating range. If the temperature exceeds the preset range (too high or too low), the heating or cooling system is automatically adjusted to maintain a suitable temperature environment and prevent chemical reactions or material stability problems caused by abnormal temperatures. The moisture control device monitors and adjusts the moisture content within the sealed container. When the detected moisture content deviates from the preset range, the system can maintain the moisture at a safe level through humidification or dehumidification measures, avoiding risks such as corrosion, short circuits caused by excessive moisture, or static electricity accumulation caused by insufficient moisture. The protective gas control device monitors the flow rate and pressure of the protective gas within the sealed container. Protective gases (such as nitrogen, argon, etc.) are used to reduce the probability of forming an explosive mixture. When the detected flow rate or pressure is not within the preset range, the system automatically adjusts the gas supply to ensure the effectiveness and safety of the protective gas.

[0057] Advantages of the above technical solution: By integrating sensors and an automatic control system, real-time and accurate monitoring of the environment inside the sealed container is achieved. Before potential hazards occur, preventive measures are taken through automatic adjustment or alarm prompts to reduce the accident risk. Dust, temperature, moisture, and protective gas are comprehensively controlled to effectively prevent explosions and other safety accidents. Microenvironment control is carried out, which facilitates the rapid construction of an environment control space. The controlled area is small, which is conducive to improving the accuracy of environment control. At the same time, it is conducive to energy conservation and emission reduction, and improves the utilization rate of resources.

[0058] According to some embodiments of the present invention, the sealed container includes a container and a glass container.

[0059] As Figure 3 shown, according to some embodiments of the present invention, the dust filtering device includes:

[0060] A laser dust counter for obtaining the dust concentration inside the sealed container;

[0061] A first control module for receiving the dust concentration sent by the laser dust counter, comparing it with a preset dust concentration threshold, and obtaining a first comparison signal;

[0062] A dust removal module for receiving the first comparison signal and performing dust filtering when it is determined that the first comparison signal indicates that the dust concentration is greater than the preset dust concentration threshold.

[0063] Working principle of the above technical solution: The laser dust counter uses the principle of laser scattering to accurately measure the dust particle concentration inside the sealed container. The laser dust counter emits a laser beam. When the laser beam encounters dust particles, scattering occurs, and the intensity of the scattered light is proportional to the number and size of the dust particles. By detecting the intensity of the scattered light, the dust concentration can be calculated. The first control module receives the dust concentration data sent by the laser dust counter and compares it with the preset dust concentration threshold. The first control module has a preset dust concentration threshold built in, which is set according to the safety operation requirements of the substances inside the sealed container. When receiving the dust concentration data sent by the laser dust counter, the first control module will immediately make a comparison and generate a first comparison signal. If the dust concentration exceeds the threshold, the first comparison signal will indicate that the dust concentration is too high. When the dust removal module receives the first comparison signal indicating that the dust concentration is too high, it starts the dust filtering process, captures and removes the dust particles in the air through a filter, thereby reducing the dust concentration inside the sealed container.

[0064] Advantages of the above technical solution: The laser dust counter provides high-precision dust concentration measurement to ensure the accuracy of monitoring results. The fast communication and response mechanism between the first control module and the dust removal module can quickly take measures when the dust concentration exceeds the standard. Through effective dust filtration treatment, the risk of forming an explosive dust cloud in the closed container is reduced, improving the safety of the system. The dust filtration device integrates a laser dust counter, a first control module, and a dust removal module to achieve precise monitoring and effective control of the dust concentration in the closed container, providing an important safety guarantee for the intelligent safety explosion-proof system.

[0065] According to some embodiments of the present invention, the temperature control device includes:

[0066] A temperature sensor for obtaining the temperature signal inside the closed container;

[0067] A second control module for receiving the temperature signal and determining whether it is within a preset temperature range to obtain a second comparison signal;

[0068] A temperature adjustment module for receiving the second comparison signal and performing temperature control processing when it is determined that the second comparison signal indicates that the temperature is not within the preset temperature range.

[0069] Working principle of the above technical solution: The temperature sensor uses technologies such as thermistors, thermocouples, or digital temperature sensors to sense the change in ambient temperature and convert it into a readable signal. The second control module receives the temperature signal from the temperature sensor and compares it with the preset temperature range. The second control module has preset temperature range thresholds, which are set according to the safe operating temperature of the substances inside the closed container. When the temperature signal is received, the second control module immediately makes a comparison and generates a second comparison signal. If the temperature exceeds the preset range (too high or too low), the second comparison signal will indicate that the temperature is abnormal. The temperature adjustment module starts temperature control processing when it receives the second comparison signal indicating temperature abnormality. The temperature adjustment module includes components such as heaters, coolers, fans, or heat exchangers. When the second control module sends a temperature abnormality signal, the temperature adjustment module will automatically start and change the temperature inside the closed container by adjusting the heating or cooling power until the temperature returns to the preset safe range.

[0070] Advantages of the above technical solution: The temperature sensor provides high-precision temperature measurement to ensure the accuracy of monitoring results. The fast communication and response mechanism between the second control module and the temperature regulation module can quickly take measures when the temperature is abnormal. Through effective temperature control processing, safety hazards such as out-of-control chemical reactions, substance stability problems, or explosions caused by too high or too low temperature can be prevented. The temperature control device realizes precise monitoring and effective control of the temperature in the closed container by integrating the temperature sensor, the second control module, and the temperature regulation module, which helps to improve the overall safety and reliability of the system.

[0071] According to some embodiments of the present invention, the moisture control device includes:

[0072] A humidity sensor for obtaining a moisture content signal in the closed container;

[0073] A third control module for receiving the moisture content signal and determining whether it is within a preset moisture content range to obtain a third comparison signal;

[0074] A humidity regulation module for receiving the third comparison signal and performing moisture control processing when it is determined that the third comparison signal indicates that the moisture content is not within the preset moisture content range.

[0075] Working principle of the above technical solution: The humidity sensor precisely measures the moisture content in the closed container and converts it into an electrical signal or a digital signal. The humidity sensor uses technologies such as capacitive, resistive, thermal conductivity, or optical to sense changes in environmental humidity. The third control module receives the moisture content signal from the humidity sensor and compares it with the preset moisture content range. The third control module has preset moisture content range thresholds built in, and these thresholds are set according to the safe operating humidity of the substance in the closed container. When receiving the moisture content signal, the third control module will immediately make a comparison and generate a third comparison signal. If the moisture content exceeds the preset range (too high or too low), the third comparison signal will indicate that the moisture content is abnormal. The humidity regulation module starts moisture control processing when it receives the third comparison signal indicating abnormal moisture content. The humidity regulation module includes components such as a humidifier, a dehumidifier, a ventilation system, or an air dryer. When the third control module sends a signal indicating abnormal moisture content, the humidity regulation module will automatically start and change the humidity by increasing or decreasing the moisture content in the closed container until the humidity returns to the preset safe range.

[0076] Beneficial effects of the above technical solution: The humidity sensor provides high-precision moisture content measurement to ensure the accuracy of monitoring results. The fast communication and response mechanism between the third control module and the humidity regulation module can quickly take measures when the moisture content is abnormal. Through effective moisture control processing, potential safety hazards such as corrosion, short circuit caused by excessive moisture content or static electricity accumulation caused by too low moisture content are prevented, ensuring the environmental stability and safety inside the closed container. The moisture control device realizes precise monitoring and effective control of the moisture content inside the closed container by integrating a humidity sensor, a third control module, and a humidity regulation module, providing an indispensable safety guarantee for the intelligent safety explosion-proof system. This integrated moisture control solution helps improve the overall performance and reliability of the system.

[0077] According to some embodiments of the present invention, the protective gas control device includes:

[0078] A flow sensor for obtaining the flow signal of the protective gas inside the closed container;

[0079] A pressure sensor for obtaining the pressure signal of the protective gas inside the closed container;

[0080] A fourth control module for receiving the flow signal, judging whether it is within the preset flow range to obtain a fourth comparison signal; receiving the pressure signal, and judging whether it is within the preset pressure range to obtain a fifth comparison signal;

[0081] A protective gas control module for receiving the fourth comparison signal and the fifth comparison signal, and performing protective gas control processing according to the fourth comparison signal and / or the fifth comparison signal.

[0082] Working principle of the above technical solution: The flow sensor accurately measures the flow rate of the protective gas in the closed container and converts it into an electrical signal or a digital signal. The flow sensor uses technologies such as thermal, differential pressure, vortex street, or magnetic induction to measure the flow velocity and flow rate of the protective gas. It can capture the flow situation of the protective gas in the closed container in real time and convert it into a readable signal for subsequent processing. The pressure sensor accurately measures the pressure of the protective gas in the closed container and converts it into an electrical signal or a digital signal. The pressure sensor uses technologies such as piezoresistive, capacitive, piezoelectric, or resonant to sense the change in the pressure of the protective gas. It can capture the pressure state of the protective gas in the closed container in real time and convert it into a readable signal for subsequent processing. The fourth control module receives the flow signal from the flow sensor and compares it with the preset flow range; at the same time, it receives the pressure signal from the pressure sensor and compares it with the preset pressure range. The fourth control module is built-in with preset flow range thresholds and pressure range thresholds, which are set according to the safety operation requirements of the substances in the closed container. When receiving the flow signal and the pressure signal, the fourth control module will immediately make a comparison and generate a fourth comparison signal and a fifth comparison signal respectively. If the flow or pressure exceeds the preset range, the corresponding comparison signal will indicate an abnormality. When the protective gas control module receives the fourth comparison signal or the fifth comparison signal indicating an abnormality, it starts the protective gas control process. The protective gas control module includes components such as a gas flow controller, a pressure regulator, a valve, or a gas supply system. When the fourth control module sends a flow or pressure abnormality signal, the protective gas control module will automatically start and maintain the flow rate and pressure of the protective gas in the closed container within a safe range by adjusting the gas flow rate, pressure, or switching the gas supply source, etc.

[0083] Advantages of the above technical solution: The flow sensor and the pressure sensor provide high-precision flow rate and pressure measurements, ensuring the accuracy of the monitoring results. The fast communication and response mechanism between the fourth control module and the protective gas control module can quickly take measures when the flow or pressure is abnormal. Through effective protective gas control processing, it prevents safety hazards such as out-of-control chemical reactions, material oxidation, and explosion caused by abnormal flow or pressure, ensuring the environmental stability and safety in the closed container. The protective gas control device realizes the accurate monitoring and effective control of the protective gas in the closed container by integrating the flow sensor, the pressure sensor, the fourth control module, and the protective gas control module.

[0084] According to some embodiments of the present invention, the system further includes: a power supply module, arranged on the upper part of the closed container; the power supply module includes a solar panel, an information collection module, a backup battery, and a fifth control module; wherein,

[0085] The solar panel is used to convert solar energy into electrical energy;

[0086] The information collection module is used to collect the working information of the solar panel, calculate the working efficiency of the solar panel according to the working information, and transmit it to the fifth control module;

[0087] The fifth control module is used to receive the working efficiency of the solar panel sent by the information collection module, compare it with a preset efficiency threshold, and when it is determined that the working efficiency is greater than or equal to the preset efficiency threshold, control the solar panel to supply power to the dust filtering device, temperature control device, moisture control device and protective gas control device in the sealed container; when it is determined that the working efficiency is less than the preset efficiency threshold, control the solar panel and the backup battery to supply power to the dust filtering device, temperature control device, moisture control device and protective gas control device in the sealed container.

[0088] The working principle of the above technical solution: The solar panel converts solar energy into electrical energy, providing green and sustainable energy for the entire system. The solar panel consists of multiple photovoltaic cells. When sunlight shines on the photovoltaic cells, photons will excite electrons in the cells, thus generating an electric current. The information collection module collects the working information of the solar panel, such as the inclined plane irradiance, the angle between the solar panel and the ground, the voltage of the solar cell, etc. It monitors the working state of the solar panel in real time and calculates its working efficiency. This efficiency value reflects the ability of the solar panel to convert solar energy into electrical energy under the current conditions. The fifth control module receives the working efficiency of the solar panel sent by the information collection module and decides whether to use the solar panel alone for power supply or to use both the solar panel and the backup battery for power supply according to the preset efficiency threshold. The fifth control module has a preset efficiency threshold built in, and this threshold is set according to the power demand of the system and the performance of the solar panel. When the working efficiency of the solar panel sent by the information collection module is greater than or equal to the preset efficiency threshold, the fifth control module will control the solar panel to supply power to the system alone. When the working efficiency is lower than the preset efficiency threshold, the fifth control module will control both the solar panel and the backup battery to supply power to the system to ensure the stable operation of the system.

[0089] The beneficial effects of the above technical solution: It makes full use of solar energy, a renewable energy source, reduces the dependence on traditional energy sources, and reduces carbon emissions. Through the collaborative work of the information collection module and the fifth control module, the real-time monitoring and intelligent adjustment of the working efficiency of the solar panel are realized, improving the energy utilization efficiency. The existence of the backup battery ensures the stable operation of the system in the absence of sunlight or when the working efficiency of the solar panel is insufficient. The power supply module is a design that integrates environmental protection, intelligence, high efficiency and stability. It provides reliable power support for each safety control device in the sealed container and makes an important contribution to the improvement of the overall performance of the intelligent safety explosion-proof system.

[0090] According to some embodiments of the present invention, the information acquisition module calculates the working efficiency η of the solar panel:

[0091]

[0092] Where q is the electron charge; V is the voltage of the solar cell connected to the solar panel; S1 is the photon flux intensity of the incident sunlight; S2 is the photon flux intensity of radiative recombination; w1 is the inclined plane irradiance received by the solar panel; k is a correction factor with a value in (0, 1); θ is the angle between the solar panel and the ground.

[0093] The working principle of the above technical solution: The working efficiency of the solar panel is an index to measure the ability of the solar panel to convert solar energy into electrical energy. q is the electron charge, which is a constant representing the electric charge carried by an electron. V is the voltage of the solar cell connected to the solar panel, which represents the potential difference generated by the solar panel under light irradiation. S1 is the photon flux intensity of the incident sunlight, which represents the number of photons irradiating on the solar panel per unit time. S2 is the photon flux intensity of radiative recombination, which represents the number of photons that fail to be successfully converted into electrical energy due to various reasons (such as lattice defects, impurities, etc.) inside the solar panel and are re-radiated. w1 is the inclined plane irradiance received by the solar panel, which represents the solar radiation energy received by the solar panel per unit area. k is a coefficient related to the installation angle of the solar panel, used to correct the difference in solar radiation due to different installation angles. θ is the angle between the solar panel and the ground, which represents the inclination angle of the solar panel relative to the ground.

[0094] The beneficial effects of the above technical solution: Considering the solar radiation energy received by the solar panel, this part of the energy is related to the inclined plane irradiance received by the solar panel and the installation angle of the solar panel. Through the inclined plane irradiance ratio and the angle correction term, we can obtain the corrected solar radiation energy. Considering the process of the solar panel converting the received solar radiation energy into electrical energy. In this process, some photons will be successfully converted into electrical energy, while some photons will fail to be successfully converted due to various reasons, that is, S2. Therefore, the converted electrical energy is expressed as qV(S1 - S2). Dividing the converted electrical energy by the corrected solar radiation energy, we can obtain the working efficiency of the solar panel. This formula comprehensively considers factors such as the voltage of the solar panel, photon flux intensity, inclined plane irradiance, inclined plane irradiance ratio, and installation angle of the solar panel, and can more accurately reflect the working efficiency of the solar panel.

[0095] According to some embodiments of the present invention, the system further includes a monitoring module for:

[0096] Obtaining the monitoring image inside the closed container;

[0097] Process the surveillance image based on the Laplacian of Gaussian function centered at 0 with a Gaussian standard deviation of σ, determine and remove discrete points to obtain the target surveillance image;

[0098]

[0099] Among them, LoG(x, y) is the Laplacian of Gaussian function; x and y are the coordinates of pixel points in the surveillance image, σ represents the standard deviation, π represents the pi, and e represents the natural constant;

[0100] When it is determined that an abnormality has occurred based on the target surveillance image, determine the abnormal area, each staff member's image, and the corresponding coordinate information;

[0101] Take the abnormal area as the first node and the coordinate information as the second node, connect the first node and the second node through a connecting edge to determine the graph data structure of each staff member; the edge weight value of the connecting edge is determined according to the distance between the staff member and the abnormal area;

[0102] Determine the risk level of each staff member according to the graph data structure of each staff member, filter out the staff members whose risk level is greater than the preset risk level, and send an alarm prompt message.

[0103] The working principle of the above technical solution: The monitoring module first obtains the surveillance image inside the closed container in real time through devices such as cameras or image sensors. The LoG function is an operator for image edge detection, which can effectively identify edges and contours in the image. By applying the LoG function, the monitoring module can determine and remove discrete points (such as noise, interference, etc.) in the image, thereby obtaining a clearer and more accurate target surveillance image. In the target surveillance image, the monitoring module uses image processing algorithms (such as object detection, image segmentation, etc.) to identify the abnormal area and each staff member's image, and extract the corresponding coordinate information. The monitoring module takes the abnormal area as the first node and the staff member's coordinate information as the second node, and connects the first node and the second node through a connecting edge to construct the graph data structure of each staff member. The edge weight value of the connecting edge is determined according to the distance between the staff member and the abnormal area, and the closer the distance, the greater the edge weight value. According to the constructed graph data structure, the monitoring module uses risk assessment algorithms (such as graph theory algorithms, machine learning models, etc.) to evaluate the risk level of each staff member. When the risk level of a certain staff member is greater than the preset risk level, the monitoring module will immediately send an alarm prompt message to notify relevant personnel to take corresponding measures in time.

[0104] Advantages of the above technical solution: The monitoring module can monitor the conditions inside the closed container in real time, quickly identify and alarm in case of abnormalities, improving the response speed and accuracy of the system. Using image processing technologies such as the Laplacian of Gaussian function, the monitoring module can remove discrete points in the image, improving the clarity and accuracy of the target monitoring image. By constructing a graph data structure and applying a risk assessment algorithm, the monitoring module can intelligently evaluate the risk level of the staff. Through the integration of advanced image processing technologies and graph data structure analysis, the monitoring module realizes the real-time monitoring of the conditions inside the closed container and intelligent risk assessment, providing a strong guarantee for the safe operation of the system.

[0105] According to some embodiments of the present invention, an energy-saving and environmentally friendly battery workshop is proposed, including battery production equipment and the intelligent safety explosion-proof system as described above.

[0106] Advantages of the above technical solution: By integrating sensors and an automatic control system, real-time and precise monitoring of the environment inside the closed container is achieved. Before potential hazards occur, preventive measures are taken through automatic adjustment or alarm prompts to reduce the accident risk. The dust, temperature, moisture, and protective gas are comprehensively controlled to effectively prevent explosions and other safety accidents. Microenvironment control is carried out, facilitating the rapid construction of an environment control space with a small control area, which is convenient for improving the accuracy of environment control, and at the same time is convenient for energy conservation and emission reduction, improving the utilization rate of resources.
