Description

Technical Field

[0001] This invention relates to data processing technology, and more particularly to a wireless intelligent fire alarm method and a stand-alone alarm device. Background Technology

[0002] Petroleum holds an irreplaceable position as an energy source for numerous sectors, including daily economic life, national industrial production, and aerospace and military industries. Oil tanks are currently one of the most important mediums for petroleum storage. While a secondary sealing technology is used on the floating roof of oil tanks, it is not completely sealed, leaving a possibility of small amounts of chemical liquids and gases leaking from the sealing rings. These leaked gases are prone to ignition under natural conditions such as high solar temperatures and lightning strikes, making fire detection particularly important.

[0003] Currently, fire alarm technology for oil storage tanks mainly relies on manual inspection. Maintenance personnel periodically inspect the tanks with portable detection equipment and assess fire risks based on experience. However, this method is limited by inspection cycles and personnel availability, making 24-hour continuous monitoring impossible. Furthermore, it lacks the ability to identify small, initial fires, leading to delayed alarms. In addition, while some tank farms have introduced stand-alone wireless alarm devices, the installation lacks scientific planning, making it difficult to quickly locate faults and further impacting alarm reliability.

[0004] Therefore, there is an urgent need to provide a wireless intelligent fire alarm method and a stand-alone alarm device that can improve the accuracy of fire alarms. Summary of the Invention

[0005] In view of the above problems, the present invention is proposed to provide a wireless intelligent fire alarm method and a stand-alone alarm device that overcomes or at least partially solves the above problems.

[0006] According to one aspect of the present invention, a wireless intelligent fire alarm method is provided, comprising the following steps: Based on the obtained top view of the corresponding oil storage tank, the analysis is carried out, and the determined idle area of ​​the oil tank is divided according to the oil level of the corresponding oil storage tank to obtain the circumferentially arranged installation areas. Install corresponding independent alarm devices in each installation area, and control each independent alarm device to collect alarm data. If the fire alarm value output by any stand-alone alarm device exceeds the preset alarm value, a fire prediction map corresponding to the stand-alone alarm device is constructed based on the top view of the oil tank and displayed. The response determines that any standalone alarm device has a fault attribute based on fault detection performed on each standalone alarm device, constructs a fault indication diagram corresponding to the standalone alarm device based on the top view of the oil tank, and displays it.

[0007] Optionally, in the method according to the present invention, analysis is performed based on the obtained top view of the corresponding oil storage tank, and the determined idle area of ​​the oil tank is divided based on the oil level height of the corresponding oil storage tank to obtain circumferentially arranged installation areas, including: An image is acquired at a preset distance and height from the oil storage tank. If the obtained top view does not completely cover the oil storage tank, the corresponding reference height is adjusted successively based on the preset distance and height. The response is based on the first top view obtained by any successive adjustment to completely cover the oil storage tank, and the first top view is determined as the top view of the oil tank. An image coordinate system is established based on the center point of the corresponding oil storage tank determined by the top view of the oil tank. The top view of the oil tank is segmented based on the image coordinate system, and secondary image acquisition is performed on the segmented regions of the oil storage tank corresponding to different coordinate quadrants to obtain the top view of each region. The top view of each region is analyzed, and the determined idle areas of the oil tanks are divided based on the oil level of the corresponding oil storage tanks to obtain the circumferentially arranged installation areas.

[0008] Optionally, in the method according to the present invention, the top view of the oil tank is segmented based on the image coordinate system, and secondary image acquisition is performed on the segmented regions of the oil storage tank corresponding to different coordinate quadrants to obtain the top view of each region, including: The top view of the oil tank is segmented based on the image coordinate axes of the corresponding image coordinate system, and the segmented regions of the oil storage tank corresponding to different coordinate quadrants are determined based on the obtained segmented images. A secondary image is acquired of the segmented region by gradually moving away from the center point of the segmented region. The secondary top view corresponding to the segmented region is located at the edge of any of the obtained secondary top views and is then determined as the region top view. The environment acquisition unit flies away from the segmented region, controls the environment acquisition unit to perform secondary image acquisition on the segmented region, and determines the secondary top view as the region top view in response to the image edge of any secondary top view corresponding to the segmented region.

[0009] Optionally, in the method according to the invention, determining the secondary top view as the region top view by responding to the segmented region corresponding to the image edge of any obtained secondary top view includes: Extract the image portion that indicates the segmentation region from the segmented image to obtain the region image; Determine the coordinate axes of the corresponding image coordinate system located in the region image, and compare each secondary top view obtained with the region image; The response determines that the region image is covered by any secondary top view based on the comparison results, and the endpoint of the line segment of the corresponding coordinate axis is located at the contour vertex of the top view contour of the corresponding secondary top view. It then determines that the segmented region is located at the image edge of any obtained secondary top view and identifies the secondary top view as the region top view.

[0010] Optionally, in the method according to the invention, the top view of each region is analyzed, and the determined idle area of ​​the oil tank is divided based on the oil level height of the corresponding oil storage tank to obtain circumferentially arranged installation areas, including: The top view of each region is divided into arrays, and the elevation of each array point is collected to obtain the elevation value of each point. If there is an elevation difference between any point elevation value and the corresponding oil storage tank reference elevation value that is outside the allowable elevation range, the array point corresponding to the elevation value of that point is determined as an occupied point, and the occupied points in adjacent positions are connected to obtain each occupied area. The installation safety distance is determined based on the oil level of the corresponding oil storage tank, and an annular installation area corresponding to the installation safety distance is formed along the outline of the corresponding oil storage tank based on the top view of the area. If there is an overlap between the ring-shaped installation area and any occupied area, the corresponding overlapping portion of the ring-shaped safety area is updated to obtain the circumferentially arranged installation areas.

[0011] Optionally, in the method according to the invention, in response to the existence of an overlap between the annular installation area and any occupied area, the annular safety area is updated for the corresponding overlapping portion to obtain circumferentially arranged installation areas, including: The annular installation area is divided into corresponding circumferential arrays to obtain preparatory areas with the same preset sensing distance. If any preparatory area overlaps with any occupied area, the center mapping point of the corresponding oil tank center point and the center preparatory point of the corresponding preparatory area are determined based on the top view of the area, and a center connection line is generated to connect the center mapping point and the center preparatory point. The control preparation area moves laterally along the annular extension direction of the corresponding annular installation area based on the overlapping part, and determines the lateral movement value corresponding to the lateral movement based on the determination that there is no overlapping part based on the lateral movement. The control area moves vertically along the central connecting line toward the central mapping point, and based on the vertical movement, it is determined that there is no overlapping part, and the corresponding vertical movement value is determined. Based on the horizontal and vertical movement values, the preparation area is updated with the minimum corresponding value to obtain the installation areas arranged circumferentially.

[0012] Optionally, in the method according to the present invention, in response to a fire alarm value output by any independent alarm device exceeding a preset alarm value, a fire prediction map corresponding to the independent alarm device is constructed based on a top view of the oil tank and displayed, including: If the fire alarm value output by any stand-alone alarm device exceeds the preset alarm value, the stand-alone alarm device is designated as the reference device, and the excess value of the corresponding preset alarm value is determined based on the fire alarm value. Starting from the reference device, the device distance between each other independent alarm device and the reference device is determined based on the circumferential arrangement, and the alarm radiation value is determined based on the device distance; The radiation consequence value for each other standalone alarm device is determined by summing the baseline alarm value and the radiation value of each alarm. If the radiation consequence value of any other stand-alone alarm device is less than the corresponding fire alarm value it outputs, the stand-alone alarm device is identified as a risk device. Based on the top view of the oil tank, the installation area of ​​the corresponding benchmark device is marked as the first mark, and the installation area of ​​the corresponding risk device is marked as the second mark, forming a fire prediction map that is sent to the management terminal for display.

[0013] Optionally, in the method according to the invention, the method further includes: Standalone alarm devices in installation areas that have not been marked with the first or second mark are identified as edge devices, and a timed task with a continuously preset duration is established for each edge device. The response is based on a timed task to determine that the fire alarm value output by any edge device for a preset duration shows an increasing trend. Based on the top view of the oil tank, the installation area of ​​the corresponding edge device will be marked in a third way.

[0014] Optionally, in the method according to the invention, the response to determining that any independent alarm device has a fault attribute based on fault detection of each independent alarm device, constructing and displaying a fault indication diagram corresponding to the independent alarm device based on a top view of the oil tank, includes: If the fire alarm value output by any stand-alone alarm device is less than the preset standard value, it is determined that the stand-alone alarm device has a fault attribute. If the radiation consequence value of other stand-alone alarm devices corresponding to any reference device is greater than or equal to the corresponding fire alarm value output by that stand-alone alarm device, it is determined that the stand-alone alarm device has a fault attribute. Based on the ring-shaped safety zone, the area between each installation area in an adjacent location is defined as the interval area, and the interval area on both sides of the stand-alone alarm device with fault attributes is defined as the identification area. Fault identifiers are generated based on the identified regions to indicate the location of stand-alone alarm devices.

[0015] According to another aspect of the present invention, a stand-alone alarm device is provided, comprising: Equipment housing; and A cover located at the top of the equipment housing for sealing the equipment housing; The device housing includes a temperature sensing unit, a processing unit for executing the wireless intelligent fire alarm method as described in any one of claims 1-8, and a battery unit for powering the temperature sensing unit and the processing unit. The processing unit is connected to a communication antenna, and a sensing probe corresponding to the temperature sensing unit extends out of the housing cover.

[0016] According to another aspect of the present invention, a wireless intelligent stand-alone fire alarm device is provided, comprising: The area planning module is configured to analyze the corresponding oil storage tank based on the obtained top view of the oil tank, and divide the determined idle area of ​​the oil tank based on the oil level of the corresponding oil storage tank to obtain the installation areas arranged in a circumferential direction. The alarm acquisition module is configured to install corresponding independent alarm devices in each installation area and control each independent alarm device to acquire alarm data. The fire prediction module is configured to respond to any standalone alarm device outputting a fire alarm value greater than a preset alarm value, and to construct and display a fire prediction map corresponding to the standalone alarm device based on the top view of the oil tank. The fault detection module is configured to respond to a fault detection of each standalone alarm device to determine if any standalone alarm device has a fault attribute, construct a fault indication diagram corresponding to the standalone alarm device based on the top view of the oil tank, and display it.

[0017] According to the solution of the present invention, the present invention can effectively solve the technical problems of alarm lag, unreasonable equipment layout, and difficulty in fault location in the traditional mode, and significantly improve the accuracy, timeliness and reliability of oil tank fire alarm, providing intelligent technical protection for oil tank safety. Specifically, it can be reflected as follows: 1. This invention divides the installation area circumferentially based on the top view of the oil tank and the height of the oil surface. It can realize the targeted layout of independent alarm devices, which can abandon the blindness of traditional random deployment or fixed-point installation. The installation points are planned only in the idle area of ​​the oil tank and evenly distributed circumferentially. This ensures that there are no blind spots in high-risk areas such as the sealing ring at the top of the oil tank. At the same time, it can accurately reach the top area of ​​the tank that is difficult for humans to reach by means of robots, avoiding the positional deviation of manual installation. This allows each independent alarm device to cover the preset monitoring range. It lays the foundation for alarm accuracy from the hardware layout level and solves the technical problems of missed monitoring of key areas and many false alarms in redundant areas caused by the lack of scientific planning in the installation of traditional equipment. 2. This invention does not require regular personnel inspections. The equipment can monitor fire-related parameters such as ambient temperature 24 hours a day without interruption. It can quickly respond to parameter changes caused by initial minor fires. Moreover, when the alarm value exceeds the preset threshold, it does not only output a simple alarm signal, but also constructs a fire prediction map based on the top view of the oil tank. That is, the specific location of the stand-alone alarm device is clearly identified through a visual chart, which indirectly locks the fire hazard area and the possible spread trend, providing accurate handling guidance for operation and maintenance personnel and greatly reducing the risk of alarm lag. 3. This invention links fault detection with a fault indication diagram, enabling rapid location and timely handling of faulty equipment. Specifically, it allows for real-time fault detection of each independent alarm device. Once a fault is detected, a fault indication diagram is immediately generated based on the top view of the oil tank, clearly marking the installation area and location of the faulty device. This solves the technical problem of difficulty in locating faults in traditional wireless independent alarm devices. Maintenance personnel no longer need to check each device individually; they can directly and accurately locate the faulty device for repair or replacement based on the indication diagram, preventing long-term failure of faulty equipment and the formation of monitoring blind spots. Furthermore, the distinct display of fault indications and fire alarms prevents misjudgments or omissions due to equipment malfunctions, ensuring the overall reliability of the alarm system and further improving the accuracy of fire alarms.

Detailed Implementation

[0018] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0019] To address the problems existing in the prior art, the inventors proposed the solution of this invention. One embodiment of this invention provides a wireless intelligent fire alarm method, which can be executed in a computing device, wherein the computing device can be understood as a terminal with data functionality, such as a mobile phone or an electrical appliance.

[0020] Figure 1 A flowchart of a wireless fire intelligent alarm method according to an embodiment of the present invention is shown, as follows: Figure 1 As shown, the method proposed in this embodiment begins with step S1, which includes the following: Based on the obtained top view of the corresponding oil storage tank, the analysis is performed, and the determined idle area of ​​the oil tank is divided according to the oil level of the corresponding oil storage tank to obtain the circumferentially arranged installation areas.

[0021] For example, in this embodiment, by obtaining a precise top view of the oil tank, analyzing idle areas, and dividing the installation area based on the oil level, the installation location of the stand-alone alarm device can be ensured to be scientifically and rationally positioned, providing a foundation for timely fire alarms. Specifically: First, this embodiment can acquire images of the corresponding oil storage tank based on the server control environment acquisition unit to obtain a top view of the oil tank that can fully present the state of the top of the oil tank. Here, the top view of the oil tank can intuitively reflect key information such as the regional distribution and the location of existing facilities on the top of the oil tank, providing a comprehensive and accurate visual basis for subsequent idle area judgment, avoiding misjudgment of installation area due to missing information, and ensuring the accuracy of idle area division. Next, the server can perform a comprehensive analysis based on the obtained top view of the oil tank to identify the idle areas of the oil tank that are not occupied by existing facilities and meet the installation conditions of independent alarm equipment. In other words, the analysis of the top view can accurately exclude areas occupied by existing equipment, pipelines, etc., to avoid conflicts in the installation of independent alarm equipment. At the same time, it ensures that the idle areas have the space conditions for equipment installation, laying the foundation for the subsequent division of installation areas and improving the rationality of installation planning. Finally, after determining the unused areas of the oil tank, the server can further divide the unused areas based on the oil level of the corresponding oil storage tank, ultimately obtaining circumferentially arranged installation areas. It can be noted that the oil level is a key safety parameter for oil storage tanks. Combining this with the division of installation areas ensures that each installation area is far away from the oil surface coverage area and potential risk areas, avoiding the impact of oil level fluctuations on the operation of independent alarm devices. At the same time, the circumferential arrangement allows the independent alarm devices to be evenly distributed on the top of the oil tank, achieving all-round coverage of the oil tank with no monitoring blind spots. This ensures that in the event of a fire in any area, nearby independent alarm devices can quickly capture the signal, greatly improving the timeliness of fire alarms and meeting the high requirements for fire prevention and control of oil storage tanks.

[0022] Furthermore, in this embodiment, the aforementioned "analysis based on the obtained top view of the corresponding oil storage tank, and division of the determined idle area of ​​the oil tank based on the oil level of the corresponding oil storage tank to obtain the circumferentially arranged installation areas" may also include the following steps: An image is acquired at a preset distance and height from the oil storage tank. If the obtained top view does not completely cover the oil storage tank, the corresponding reference height is adjusted successively based on the preset distance and height. The response is based on the first top view obtained by any successive adjustment to completely cover the oil storage tank, and the first top view is determined as the top view of the oil tank. An image coordinate system is established based on the center point of the corresponding oil storage tank determined by the top view of the oil tank. The top view of the oil tank is segmented based on the image coordinate system, and secondary image acquisition is performed on the segmented regions of the oil storage tank corresponding to different coordinate quadrants to obtain the top view of each region. The top view of each region is analyzed, and the determined idle areas of the oil tanks are divided based on the oil level of the corresponding oil storage tanks to obtain the circumferentially arranged installation areas.

[0023] For example, in this embodiment, the analysis based on the obtained top view of the oil tank to determine each installation area can be specifically implemented based on the following method steps: First, the server can control the environmental acquisition unit to fly to a acquisition position at a preset distance and height from the oil storage tank to acquire an image. Here, the preset distance and height is a preliminary acquisition height based on the common size of oil storage tanks, providing a basic positional reference for the initial image acquisition. At the same time, the server can judge the coverage of the obtained top view. If the top view does not completely cover the oil storage tank, it means that the current acquisition height cannot completely capture the information of the top of the tank. At this time, the server controls the environmental acquisition device to adjust the corresponding reference height step by step based on the preset distance and height. It can be noted that the step-by-step adjustment method can avoid the acquisition deviation caused by a large adjustment at once. By gradually optimizing the acquisition height, it is ensured that a top view that completely covers the oil storage tank can be obtained in the end, providing complete image data of the top of the tank for subsequent analysis and avoiding misjudgment of the installation area due to missing area information. Subsequently, the response completely covers the oil storage tank with a top view obtained from each successive adjustment. The server can determine this top view as the top view of the oil tank. As mentioned above, the fully covered top view of the oil tank can completely present key information such as the regional distribution and facility location on the top of the oil tank, providing a reliable image basis for subsequent idle area judgment and installation area division. Furthermore, the server can establish an image coordinate system based on the center point of the corresponding oil storage tank determined based on the top view of the oil tank. Here, establishing a coordinate system based on the center point of the oil tank can provide a unified coordinate reference for subsequent image segmentation and area positioning, avoiding deviations in area location judgment caused by inconsistent reference standards and improving the accuracy of subsequent operations. Next, the server can segment the top view of the oil tank based on the established image coordinate system, thereby decomposing the complete top view of the oil tank into segmented regions corresponding to different coordinate quadrants. It can be explained that by segmenting according to coordinate quadrants, the complex top area of ​​the oil tank can be decomposed into multiple independent small areas, which facilitates the subsequent targeted collection of detailed information of each area and avoids blurring of local details due to the large size of a single image acquisition. Then, after completing the division of the segmented areas, the server can control the environmental acquisition unit to perform secondary image acquisition on the segmented areas corresponding to different coordinate quadrants of the oil storage tank, and obtain the top view of each area. Since the secondary acquisition focuses on the segmented small areas, it can obtain clearer area details, ensuring that key information is not missed when judging the idle areas in the future, and further improving the accuracy of the installation area division. Finally, after obtaining the corresponding area top view, the server can perform detailed analysis on each area top view, accurately identifying the occupied and idle areas on the top of the oil storage tank based on image details. At the same time, combined with the oil level height of the corresponding oil storage tank, the identified idle areas of the tank are divided, ultimately resulting in circumferentially arranged installation areas. It can be noted that the detailed analysis of the area top view ensures accurate identification of idle areas, avoiding misjudging occupied areas as idle areas. At the same time, the division based on oil level height ensures that the installation areas are far away from oil surface coverage and potential risk areas. Furthermore, the circumferentially arranged installation areas enable the independent alarm equipment to achieve omnidirectional coverage of the top of the oil tank, with no monitoring blind spots. This provides accurate location information for the subsequent deployment of independent alarm equipment, ensuring that the independent alarm equipment can quickly capture signals when a fire occurs, significantly improving the timeliness of fire alarms.

[0024] In this embodiment, the environmental acquisition unit may be, for example, a drone that integrates image acquisition and elevation acquisition functions. The specific implementation of the environmental acquisition unit is not specifically limited in this embodiment. In another implementation, the environmental acquisition unit may also be implemented based on a tracked robot, which will not be described in detail in this embodiment.

[0025] Furthermore, in this embodiment, the aforementioned "segmenting the top view of the oil tank based on the image coordinate system, and performing secondary image acquisition on the segmented regions corresponding to different coordinate quadrants of the oil storage tank to obtain the top view of each region" may further include the following steps: The top view of the oil tank is segmented based on the image coordinate axes of the corresponding image coordinate system, and the segmented regions of the oil storage tank corresponding to different coordinate quadrants are determined based on the obtained segmented images. A secondary image is acquired of the segmented region by gradually moving away from the center point of the segmented region. The secondary top view corresponding to the segmented region is located at the edge of any of the obtained secondary top views and is then determined as the region top view. The environment acquisition unit flies away from the segmented region, controls the environment acquisition unit to perform secondary image acquisition on the segmented region, and determines the secondary top view as the region top view in response to the image edge of any secondary top view corresponding to the segmented region.

[0026] For example, in this embodiment, obtaining the corresponding region top view based on secondary image acquisition can be specifically achieved based on the following method steps: First, the server can segment the top view of the oil tank based on the image coordinate axes of the corresponding image coordinate system. It should be noted that the image coordinate axes are a unified coordinate reference previously established based on the center point of the oil tank. Using this as the basis for segmentation can ensure that the segmented area corresponds accurately to the coordinate quadrant, avoiding blurred segmentation boundaries or misalignment of areas, and making the positional information of each segmented area clear and specific. At the same time, after acquiring the segmented image, the server can determine the segmented areas of the oil storage tank corresponding to different coordinate quadrants based on the segmented image. Here, the clear segmentation of the area can break down the top of the oil tank into multiple independent units that are easy to analyze in detail, laying the foundation for subsequent targeted collection of details of each area and avoiding the omission of local information due to the large overall image. Next, the server can control the environmental acquisition unit to stop at the center point of each segmented area. Since the center point is the geometric center of the segmented area, controlling the acquisition unit to stop here can ensure that the lens can evenly cover the entire segmented area during subsequent secondary acquisitions, avoiding the loss of area edge information due to acquisition position offset. In addition, using the area center point as the starting position for acquisition can ensure that the acquisition standards of different segmented areas are consistent, improve the comparability of the top view of each area, and provide a unified reference for subsequent cross-regional idle area judgment. Subsequently, the environmental acquisition unit flies away from the segmented area. The server can control the environmental acquisition unit to perform secondary image acquisition on the segmented area. It can be explained that controlling the environmental acquisition unit to fly away from the segmented area can gradually expand the acquisition field of view, ensuring that the secondary top view can cover the complete range of the segmented area and avoid incomplete regional information due to the acquisition distance being too close. Finally, after obtaining the secondary top view, the server can perform edge determination on the secondary top view. If the corresponding segmented area is located at the image edge of any of the obtained secondary top views, it means that the secondary top view has completely captured the boundary and details of the segmented area. At this time, the server can determine the secondary top view as the area top view, ensuring that the area top view not only completely covers the segmented area but also has clear detail information. This provides high-quality image data for subsequent accurate analysis of the occupancy status of the segmented area and the division of idle areas, thereby ensuring accurate division of the installation area, ensuring that the stand-alone alarm equipment is deployed without blind spots, and improving the timeliness of fire alarms.

[0027] Furthermore, in this embodiment, the aforementioned "responding to the image edge of any obtained secondary top view corresponding to the segmented region, and determining the secondary top view as the region top view" may further include the following steps: Extract the image portion that indicates the segmentation region from the segmented image to obtain the region image; Determine the coordinate axes of the corresponding image coordinate system located in the region image, and compare each secondary top view obtained with the region image; The response determines that the region image is covered by any secondary top view based on the comparison results, and the endpoint of the line segment of the corresponding coordinate axis is located at the contour vertex of the top view contour of the corresponding secondary top view. It then determines that the segmented region is located at the image edge of any obtained secondary top view and identifies the secondary top view as the region top view.

[0028] For example, in this embodiment, determining the top view of a region based on the image edge of any obtained secondary top view corresponding to the segmented region can be specifically implemented based on the following method steps: First, the server can extract the image portion that indicates the segmentation region from the segmented image to obtain the corresponding region image. It can be noted that the segmented image is the image obtained by segmenting the top view of the oil tank based on the image coordinate system. Extracting the portion that indicates the segmentation region can separate the complete outline of the segmentation region and form a clear benchmark template. This avoids interference from other irrelevant image regions during subsequent comparisons, ensuring the uniqueness and accuracy of the comparison object and laying a clear reference foundation for subsequent judgment on whether the secondary top view meets the requirements. Next, the server can determine the coordinate axes of the corresponding image coordinate system in the regional image. The image coordinate system is a unified spatial reference previously established based on the center point of the oil tank. Defining the coordinate axes in the regional image can provide a unified positional reference standard for the comparison of the secondary top views, avoiding positional judgment deviations caused by the lack of coordinate reference. At the same time, the server can compare each obtained secondary top view with the regional image one by one. Here, through pixel-level comparison, it can intuitively determine whether the secondary top view covers the regional image, whether the coverage is complete, and whether the position of the coordinate axes in the secondary top view meets the requirements. This provides a quantitative basis for subsequent edge determination, replacing subjective visual observation and greatly improving the objectivity and accuracy of the comparison results. Finally, based on the comparison results, if the region image is covered by any secondary top view and the endpoints of the corresponding coordinate axis line segments are located at the vertices of the top view contour of the corresponding secondary top view, the server can clearly identify that the segmented region is located at the edge of the image in that secondary top view. It can be explained that the coverage of the region image ensures that the secondary top view completely captures all the details of the segmented region without missing information, avoiding incomplete analysis of the subsequent idle region due to missing images. The endpoints of the coordinate axis line segments being located at the vertices of the top view contour further verify that the segmented region is located at the edge range in the secondary top view, ensuring that the field of view of the secondary top view is wide enough to fully present the boundary and surrounding environment of the segmented region. This provides sufficient image information for subsequent accurate identification of occupied areas and division of idle areas, ensuring the integrity and accuracy of the region top view. It also provides high-quality image data for subsequent installation area division, thereby ensuring that the independent alarm equipment can be deployed evenly and without blind spots on the top of the oil storage tank, ensuring that the independent alarm equipment can quickly capture signals when a fire occurs, and greatly improving the timeliness of oil storage tank fire alarms.

[0029] In addition, in this embodiment, the above-mentioned "analyzing the top view of each region and dividing the determined idle areas of the oil tanks based on the oil level height of the corresponding oil storage tanks to obtain the circumferentially arranged installation areas" may also include the following steps: The top view of each region is divided into arrays, and the elevation of each array point is collected to obtain the elevation value of each point. If there is an elevation difference between any point elevation value and the corresponding oil storage tank reference elevation value that is outside the allowable elevation range, the array point corresponding to the elevation value of that point is determined as an occupied point, and the occupied points in adjacent positions are connected to obtain each occupied area. The installation safety distance is determined based on the oil level of the corresponding oil storage tank, and an annular installation area corresponding to the installation safety distance is formed along the outline of the corresponding oil storage tank based on the top view of the area. If there is an overlap between the ring-shaped installation area and any occupied area, the corresponding overlapping portion of the ring-shaped safety area is updated to obtain the circumferentially arranged installation areas.

[0030] For example, in this embodiment, determining the installation area based on the analysis of the top view of the area can be achieved through the following specific method steps: First, the server can divide the top view of each region into an array, thereby breaking down the top view of the region into regularly arranged array points. It can be noted that the array division involved in this embodiment can achieve grid-like coverage of the top view of the region, ensuring that no region is missed, and providing clear point basis for subsequent fine-grained acquisition. At the same time, the server's further controllable environmental acquisition unit performs elevation acquisition on each array point to obtain the elevation value of each point. Since elevation acquisition can distinguish whether there are protrusions or occupancy of array points through height data, it can avoid the omission of subtle occupancy areas caused by relying solely on image visual judgment, and improve the accuracy of occupancy area identification. Next, if there is an elevation difference between any point elevation value and the corresponding oil tank reference elevation value that is outside the allowable elevation range, it indicates that the array point has an abnormal protrusion or is occupied by other facilities. At this time, the server can identify the array point corresponding to the elevation value of the point as the occupied point, and further connect the occupied points in adjacent positions to obtain each occupied area. That is, by connecting adjacent occupied points, a complete outline of the occupied area can be formed, clarifying the uninstallable range on the top of the oil tank, avoiding conflicts between the subsequent installation area and the occupied area, ensuring that there are no physical obstacles to the installation position of the independent alarm device, and ensuring the normal operation of the device. Subsequently, the server can determine the installation safety distance based on the oil level height of the corresponding oil storage tank. It should be noted that the oil level height is directly related to the fire risk range of the oil storage tank. Setting the installation safety distance can ensure that the independent alarm device is far away from the area that may be affected by oil level fluctuations, avoiding equipment failure or signal distortion caused by oil level factors. After determining the installation safety distance, the server can further form a ring-shaped installation area corresponding to the installation safety distance based on the top view of the area along the outline of the corresponding oil storage tank. This lays the foundation for the subsequent circumferentially arranged installation areas, initially achieving ring-shaped coverage of the top of the oil tank, and providing a layout framework for the all-round monitoring of the independent alarm device. Finally, if the ring-shaped installation area overlaps with any occupied area, it indicates that there are conflicting areas in the initially formed ring-shaped area that cannot be installed. At this time, the server can update the corresponding overlapping parts of the ring-shaped installation area. Here, the corresponding update process can remove the parts of the ring-shaped area that overlap with the occupied area, ensuring that the final installation areas are all conflict-free and risk-free usable areas. Through the above updates, the installation areas are finally arranged in a circumferential pattern. The circumferential arrangement of the installation areas allows the independent alarm devices to be evenly distributed on the top of the oil tank, achieving full coverage without monitoring blind spots. This ensures that when a fire occurs, the nearby independent alarm devices can quickly capture the fire signal, greatly improving the timeliness of fire alarms in oil storage tanks and meeting the high requirements of fire prevention and control.

[0031] It can be explained that, in order to ensure the airtightness of oil storage tanks, the structure of oil storage tanks generally includes a floating roof (single-disc or double-disc), tank walls, tank bottom, and sealing devices. When pumping oil, the floating roof will descend with the oil level, and the top will also decrease. When it descends, the corresponding amount of oil may accumulate on the exposed tank walls. Therefore, in order to prevent the accumulation and sliding of oil from damaging the independent alarm device, this invention can set the corresponding installation safety distance based on the oil level (which can be understood as the height of the highest oil level when storing oil). The greater the oil level, the greater the amount of oil that may continuously accumulate on the surface, and therefore the higher the installation safety distance should be.

[0032] Furthermore, in this embodiment, the aforementioned "responding to the overlap between the annular installation area and any occupied area, updating the corresponding overlapping portion of the annular safety area to obtain the circumferentially arranged installation areas" may further include the following steps: The annular installation area is divided into corresponding circumferential arrays to obtain preparatory areas with the same preset sensing distance. If any preparatory area overlaps with any occupied area, the center mapping point of the corresponding oil tank center point and the center preparatory point of the corresponding preparatory area are determined based on the top view of the area, and a center connection line is generated to connect the center mapping point and the center preparatory point. The control preparation area moves laterally along the annular extension direction of the corresponding annular installation area based on the overlapping part, and determines the lateral movement value corresponding to the lateral movement based on the determination that there is no overlapping part based on the lateral movement. The control area moves vertically along the central connecting line toward the central mapping point, and based on the vertical movement, it is determined that there is no overlapping part, and the corresponding vertical movement value is determined. Based on the horizontal and vertical movement values, the preparation area is updated with the minimum corresponding value to obtain the installation areas arranged circumferentially.

[0033] For example, in this embodiment, updating the annular safety area based on the overlapping portion to obtain the installation area can be specifically implemented based on the following method steps: First, the server can divide the ring-shaped installation area into corresponding circumferential arrays to obtain preparatory areas with the same preset sensing distance. Here, the circumferential array division ensures that the initial preparatory areas are evenly distributed along the ring. The preset sensing distance is a fixed interval set based on the monitoring range of the stand-alone alarm device, which can avoid the subsequent deployment of devices being too dense or too sparse, laying the foundation for full coverage monitoring of the stand-alone alarm device. Furthermore, the clear division of preparatory areas makes subsequent overlap judgment and position adjustment more targeted, avoiding the confusion caused by overall adjustment of the ring area. Next, if any prepared area overlaps with any occupied area, it indicates that the prepared area cannot be directly used as an installation area and needs to be adjusted. At this time, the server can determine the center mapping point of the corresponding oil tank center point (that is, the projection position of the oil tank center point in the area top view) and the center prepared point of the corresponding prepared area (that is, the geometric center position of the prepared area) based on the area top view, and generate a center connection line connecting the center mapping point and the center prepared point. It can be noted that the positioning of the center mapping point and the center prepared point can provide a clear reference benchmark for the subsequent movement of the prepared area, and the center connection line determines the movement path of the prepared area towards the center of the oil tank, ensuring that the adjustment process is systematic and avoiding new conflicts caused by blind movement. Subsequently, the server can control the preparation area to move laterally along the circumferential extension direction of the corresponding annular installation area based on the overlapping part. Since the circumferential extension direction is the circumferential direction of the annular installation area, moving along this direction can avoid overlapping with the occupied area while keeping the relative distance between the preparation area and the outline of the oil tank unchanged. At the same time, the server continuously monitors the movement process. Furthermore, when it is determined that there is no overlapping part based on the lateral movement, the server can control the movement to stop and determine the corresponding lateral movement value. Here, the lateral movement can quickly avoid overlapping conflicts with the same annular position, and the recording of the movement value provides data support for the subsequent selection of the optimal adjustment method, ensuring that the adjustment process is efficient and quantifiable. Simultaneously, the server can also control the preparation area to move vertically along the central connecting line towards the central mapping point (i.e., towards the center of the oil tank). Here, similar to the horizontal movement, the vertical movement can also adjust the distance between the preparation area and the center of the oil tank, making up for the overlap that cannot be avoided by the horizontal movement. Similarly, the movement process is continuously monitored, and when it is determined that there is no overlap based on the vertical movement, the movement is stopped and the corresponding vertical movement value is determined. By combining the vertical movement and the horizontal movement, a two-way adjustment test mechanism is formed to ensure that the preparation area achieves minimal movement and no overlap based on two different movement methods, reducing the impact on other preparation areas. Finally, the server can update the preparation area based on the horizontal and vertical movement values, with the corresponding minimum values. That is, it can choose the adjustment method with smaller movement values ​​(horizontal or vertical movement) to fix the position of the preparation area, resulting in a non-overlapping usable area. This can maximize the preservation of the initial distribution state of the preparation area and avoid imbalance in equipment spacing due to excessive movement. Furthermore, by updating all overlapping preparation areas in the above way, the installation areas arranged in a circumferential manner can be obtained. This allows the independent alarm devices to fully cover the top of the oil storage tank without monitoring blind spots, ensuring that the equipment can quickly capture signals when a fire occurs, and greatly improving the timeliness of oil storage tank fire alarms.

[0034] Step S2 includes the following: Install corresponding independent alarm devices in each installation area, and control each independent alarm device to collect alarm data.

[0035] For example, in this embodiment, a flying-type equipment installation unit can be used to achieve precise deployment and synchronous alarm acquisition of stand-alone alarm devices, ensuring that the stand-alone alarm devices take effect quickly and continuously monitor. Specifically: First, the server controls the equipment installation units to fly to each installation area. Here, the equipment installation units have flight capabilities, which can get rid of the space restrictions on the top of the oil storage tank. The equipment can be transported and installed without personnel entering high-risk areas, which greatly reduces personnel safety hazards. In addition, the installation areas are circumferentially arranged areas based on the analysis of the top view of the oil tank and the oil level. The positions are accurate and there is no occupation conflict. The equipment installation units fly directly to the corresponding areas, which can avoid equipment deployment errors caused by installation position deviations. This ensures that each installation area can be accurately matched with an independent alarm device, laying the foundation for subsequent comprehensive monitoring. Next, after the equipment installation unit arrives at each installation area, the server can further control it to perform the installation operation of the corresponding stand-alone alarm device. That is, the equipment installation unit can preset the installation clamps or fixing mechanisms that match the stand-alone alarm device, which can quickly complete the positioning and fixing of the stand-alone alarm device. Compared with manual installation, the installation efficiency is higher and the stability is stronger, avoiding equipment loosening or displacement caused by human operation errors, ensuring that the stand-alone alarm device can stably collect signals during subsequent use, and reducing the risk of collection failure due to equipment installation problems. Finally, after each stand-alone alarm device is installed, the server can immediately control that device to collect alarm data, ensuring that the data collection parameters of all stand-alone alarm devices are consistent. This avoids delays or false alarms caused by inconsistent parameters, allowing all stand-alone alarm devices to form a collaborative monitoring network that fully covers the top area of ​​the oil storage tank. In the event of a fire, nearby stand-alone alarm devices can detect abnormal signals and trigger alarms immediately, significantly improving the timeliness of oil storage tank fire alarms.

[0036] In addition, the equipment installation unit in this embodiment can also be implemented based on a tracked robot.

[0037] Step S3 includes the following: If the fire alarm value output by any stand-alone alarm device exceeds the preset alarm value, a fire prediction map corresponding to the stand-alone alarm device is constructed based on the top view of the oil tank and displayed.

[0038] For example, in this embodiment, fire information can be visualized and rapidly transmitted by real-time monitoring of alarm values, constructing a predictive map by associating it with the top view of the oil tank, and promptly pushing the data to the management terminal. Specifically: First, the server continuously monitors the fire alarm value output by each independent alarm device (where the fire alarm value is a quantified value of fire-related parameters such as temperature and smoke concentration collected by the independent alarm device), and compares it with the preset alarm value in real time. The corresponding preset alarm value is a safety threshold set based on the fire risk level of the oil storage tank, which can accurately distinguish between normal environmental signals and abnormal fire signals, avoiding false alarms or missed alarms due to improper threshold settings. When the fire alarm value output by any independent alarm device is detected to be greater than the preset alarm value, the subsequent fire prediction map construction process is immediately triggered to ensure that the response can be started quickly after the fire signal is captured, thus buying time for subsequent emergency handling. Next, after triggering the response, the server can construct a fire prediction map corresponding to the stand-alone alarm device based on the previously acquired top view of the oil tank. It can be explained that the top view of the oil tank can completely present key spatial information such as the distribution of installation areas on the top of the oil storage tank and the location of the stand-alone alarm device. Based on this, the prediction map can accurately associate the location of the stand-alone alarm device with the fire alarm information. That is, the installation area of ​​the stand-alone alarm device that outputs a fire alarm value exceeding the threshold can be clearly marked in the top view of the oil tank, intuitively showing the suspected location of the fire. At the same time, based on the monitoring range of the stand-alone alarm device, the potential fire impact range can be initially marked in the prediction map, providing spatial reference for the management to quickly assess the fire situation and avoiding assessment delays caused by ambiguous location information. After the fire prediction map is constructed, the server can immediately send it to the management end for display.

[0039] It can be explained that, in this embodiment, the management terminal can be understood as the terminal used by the management personnel, such as a mobile phone or computer. It can receive and display fire prediction maps in real time, allowing management personnel to quickly grasp the specific location and potential impact range of the fire through visual images without on-site investigation, greatly shortening the fire situation assessment time. At the same time, a clear fire prediction map can provide a direct basis for management personnel to formulate emergency response plans, avoid handling errors caused by unclear information, further improve the emergency response efficiency after the oil storage tank fire alarm, ensure that the fire can be controlled in a timely manner, and meet the high requirements of fire prevention and control for alarm timeliness.

[0040] Furthermore, in this embodiment, the aforementioned "responding to a fire alarm value output by any independent alarm device being greater than a preset alarm value, constructing a fire prediction map corresponding to the independent alarm device based on the top view of the oil tank, and displaying it" may also include the following steps: If the fire alarm value output by any stand-alone alarm device exceeds the preset alarm value, the stand-alone alarm device is designated as the reference device, and the excess value of the corresponding preset alarm value is determined based on the fire alarm value. Starting from the reference device, the device distance between each other independent alarm device and the reference device is determined based on the circumferential arrangement, and the alarm radiation value is determined based on the device distance; The radiation consequence value for each other standalone alarm device is determined by summing the baseline alarm value and the radiation value of each alarm. If the radiation consequence value of any other stand-alone alarm device is less than the corresponding fire alarm value it outputs, the stand-alone alarm device is identified as a risk device. Based on the top view of the oil tank, the installation area of ​​the corresponding benchmark device is marked as the first mark, and the installation area of ​​the corresponding risk device is marked as the second mark, forming a fire prediction map that is sent to the management terminal for display.

[0041] For example, in this embodiment, the formation of the fire prediction map can be achieved based on the following method steps: First, in response to any standalone alarm device outputting a fire alarm value greater than a preset alarm value, the server can designate that standalone alarm device as the baseline device. It can be explained that the baseline device is the initial triggering source of the fire signal, and identifying its identity can provide a core reference starting point for subsequent analysis of the fire spread range. At the same time, based on the difference between the fire alarm value output by the baseline device and the preset alarm value, the excess value of the corresponding preset alarm value can be determined. It should be further noted that the excess value quantifies the fire risk intensity at the baseline device. The larger the excess value, the stronger the initial fire signal and the higher the potential spread risk, providing a quantitative basis for subsequent judgment of the radiation impact of other standalone alarm devices. Next, after determining the reference device, the server can use the reference device as a starting point and, based on the previously divided circumferential installation area, determine the device distance between each of the other independent alarm devices and the reference device. Since the device distance is a physical distance calculated based on the spatial distribution of the installation area, it can intuitively reflect the proximity of other independent alarm devices to the initial point of the fire. After determining the device distance, the server can determine the alarm radiation value based on the device distance. It can be noted that the closer the device is, the greater its corresponding alarm radiation value, that is, the higher the possibility of being affected by the fire at the reference device. Conversely, the farther the device is, the smaller its alarm radiation value, that is, the lower the possibility of being affected. Here, this embodiment can preliminarily predict the potential impact of the fire on the surrounding independent alarm device area by correlating the device distance with the alarm radiation value, avoiding focusing only on a single device and ignoring the overall risk. Subsequently, the server can sum the fire alarm value of the reference device and the alarm radiation value of each other independent alarm device to determine the radiation consequence value of each other independent alarm device. It can be noted that the radiation consequence value comprehensively considers the initial fire intensity and the distance between devices, and can more accurately assess the degree of fire impact that each other independent alarm device area may be affected by. In addition, the radiation consequence value of each other independent alarm device is compared with its actual output fire alarm value. If the radiation consequence value of any other independent alarm device is less than its corresponding output fire alarm value, it means that the fire signal at that independent alarm device is not only affected by the radiation of the reference device, but there may be an independent fire point or the fire has spread to the area. At this time, the independent alarm device can be identified as a risk device, and other high-risk areas besides the reference device can be accurately identified to avoid missing potential fire points. Finally, based on the top view of the oil tank, the server can mark the installation area of ​​the corresponding baseline equipment as the first marker (e.g., a red highlight to clearly identify the initial fire triggering area) and the installation area of ​​the corresponding risk equipment as the second marker (e.g., an orange highlight to clearly identify the secondary risk area). By distinguishing the risk levels through different markers, managers can quickly focus on the core risk areas. At the same time, the top view of the oil tank containing the first and second markers is identified as a fire prediction map and sent to the management terminal for display. Thus, based on the visualized fire prediction map, the management terminal can intuitively grasp the specific location and risk level of the initial fire point and secondary risk points, quickly assess the fire situation without additional investigation, significantly shorten the emergency response time, ensure that managers can formulate targeted disposal plans in a timely manner, and effectively improve the timeliness and accuracy of oil tank fire alarms and disposal.

[0042] Furthermore, if only the installation areas corresponding to the baseline equipment and risk equipment are marked, without paying attention to the status changes of unmarked stand-alone alarm equipment, potential fire risks in edge equipment areas may be overlooked. For example, some edge equipment may have already shown an increasing fire alarm value but have not yet reached the risk assessment threshold. If not monitored and marked in time, the fire may only be discovered when it has spread to the edge area, delaying the alarm timing. Therefore, in order to solve this technical problem, this embodiment may further include the following steps: Standalone alarm devices in installation areas that have not been marked with the first or second mark are identified as edge devices, and a timed task with a continuously preset duration is established for each edge device. The response is based on a timed task to determine that the fire alarm value output by any edge device for a preset duration shows an increasing trend. Based on the top view of the oil tank, the installation area of ​​the corresponding edge device will be marked in a third way.

[0043] For example, in this embodiment, the third marker for the edge device can be implemented based on the following method steps: First, the server can identify stand-alone alarm devices in installation areas that have not been marked with the first or second mark as edge devices. It should be noted that, based on the aforementioned content, the first mark corresponds to the baseline device (the initial fire triggering device), and the second mark corresponds to the risk device (the device affected by fire radiation or the device with an independent fire point). Although the unmarked edge devices do not currently meet the high-risk judgment criteria, they are still an important part of oil tank fire monitoring. Therefore, by clarifying the identity of edge devices, we can avoid ignoring edge areas by only focusing on high-risk devices, ensuring that all stand-alone alarm devices are included in the monitoring scope, and laying the foundation for subsequent comprehensive risk warning. Next, the server can establish a timed task with a continuously preset duration based on each edge device. In this embodiment, the preset duration is a fixed monitoring cycle (e.g., 5 minutes) set based on the fire spread speed of the oil storage tank and the collection frequency of the independent alarm device. This ensures that multiple data collections and trend analyses are completed within the time that the fire may spread to the edge area. After the timed task is started, the server will continuously monitor the fire alarm value output by the corresponding edge device and record data changes in real time to avoid trend misjudgment caused by a single monitoring and ensure that subtle changes in the fire alarm value of the edge device can be accurately captured. Finally, the response indicates that the fire alarm value output by any edge device for a preset duration, determined by a timed task, shows an increasing trend. This suggests that the fire risk in the area of ​​that edge device is rising, potentially signaling fire spread or the budding of a localized fire. At this point, the server can add a third marker (e.g., a yellow highlight, distinguishing the risk level from the first and second markers) to the installation area of ​​the corresponding edge device based on the top view of the oil tank. This third marker allows the management to promptly grasp the risk changes in the edge area, enabling early intervention without waiting for the fire alarm value of the edge device to reach a high-risk threshold. Furthermore, the dynamic marking method ensures that the fire prediction map can be updated in real time with the risk status of the edge devices, avoiding information lag caused by static marking. This allows management personnel to comprehensively and promptly grasp the fire risk in each area of ​​the oil storage tank, providing a basis for early deployment of emergency measures, further improving the timeliness of fire alarms in oil storage tanks, and effectively curbing the spread of fire.

[0044] Step S4 includes the following: The response determines that any standalone alarm device has a fault attribute based on fault detection performed on each standalone alarm device, constructs a fault indication diagram corresponding to the standalone alarm device based on the top view of the oil tank, and displays it.

[0045] For example, in this embodiment, the faulty equipment can be identified through fault detection, a fault indication diagram can be constructed by associating it with the upper view of the oil tank, and the information can be promptly pushed to the management terminal to achieve accurate location and visual transmission of fault information. Specifically: First, the server can continuously detect faults in each stand-alone alarm device. Fault detection is achieved by monitoring the output data of the stand-alone alarm devices, ensuring that abnormal device states can be fully captured. When it is determined from the fault detection results that any stand-alone alarm device cannot perform the fire alarm acquisition function normally, it can be determined that the stand-alone alarm device has fault attributes, avoiding faulty devices from being hidden in the monitoring network for a long time and forming blind spots, and providing a clear target for subsequent fault handling. Secondly, after identifying the stand-alone alarm devices with fault attributes, the server can construct a fault indication diagram corresponding to the stand-alone alarm devices based on the previously obtained top view of the oil tank. Since the top view of the oil tank fully presents the distribution of the installation area on the top of the oil storage tank and the positional relationship of each stand-alone alarm device, constructing a fault indication diagram based on it can accurately associate the faulty device with a specific spatial location. Therefore, in the top view of the oil tank, the installation area of ​​the stand-alone alarm device with fault attributes can be clearly marked by specific labels, intuitively displaying the location of the faulty device and making the fault status clear at a glance. Finally, after the fault indication diagram is constructed, the server can send it to the management terminal for display. As mentioned above, since the management terminal is used by management personnel, receiving and displaying the fault indication diagram in real time allows management personnel to quickly grasp the specific location and fault status of the faulty equipment through visual images without on-site inspections. This significantly shortens the fault location time, ensures that the faulty equipment can be restored to normal operation as soon as possible, reduces the duration of monitoring blind spots, ensures the integrity and effectiveness of the oil storage tank fire alarm system, and thus improves the timeliness of fire alarms, meeting the high requirements for fire prevention and control of oil storage tanks.

[0046] Furthermore, in this embodiment, the aforementioned "response based on fault detection of each independent alarm device to determine that any independent alarm device has a fault attribute, constructing a fault indication diagram corresponding to the independent alarm device based on the top view of the oil tank, and displaying it" may also include the following steps: If the fire alarm value output by any stand-alone alarm device is less than the preset standard value, it is determined that the stand-alone alarm device has a fault attribute. If the radiation consequence value of other stand-alone alarm devices corresponding to any reference device is greater than or equal to the corresponding fire alarm value output by that stand-alone alarm device, it is determined that the stand-alone alarm device has a fault attribute. Based on the ring-shaped safety zone, the area between each installation area in an adjacent location is defined as the interval area, and the interval area on both sides of the stand-alone alarm device with fault attributes is defined as the identification area. Fault identifiers are generated based on the identified regions to indicate the location of stand-alone alarm devices.

[0047] For example, in this embodiment, the establishment of the fault indication diagram can be specifically implemented based on the following method steps: First, the server continuously monitors the fire alarm value output by each stand-alone alarm device and compares it with a preset standard value. The preset standard value is the basic signal threshold that the stand-alone alarm device should output when it is working normally. For example, the baseline values ​​corresponding to the ambient temperature and smoke concentration when there is no fire. If the fire alarm value output by any stand-alone alarm device is less than the preset standard value, it indicates that the device may have problems such as signal acquisition failure or sensor failure, and cannot output a valid monitoring signal normally. At this time, the server can determine that the stand-alone alarm device has fault attributes, and can quickly identify faulty devices with abnormal signals, thus avoiding monitoring blind spots caused by device failure. Next, in a scenario where a reference device (a device whose output fire alarm value is greater than a preset alarm value) exists, the server can calculate the radiation consequence value of other independent alarm devices corresponding to any reference device (that is, the sum of the reference alarm value and the alarm radiation value of that device), and compare it with the fire alarm value output by the other independent alarm devices. If the response radiation consequence value is greater than or equal to the fire alarm value output by the corresponding device, it indicates that the independent alarm device does not truly reflect the actual situation affected by the fire of the reference device, and may have faults such as signal transmission delay or data calculation errors, and cannot accurately participate in the fire risk linkage analysis. At this time, it is determined that the independent alarm device has fault attributes, and then the faulty devices with linkage failure can be identified to avoid the deviation in fire judgment caused by abnormal device linkage. Finally, after identifying the stand-alone alarm devices with fault attributes, the server can define the area between adjacent installation areas as interval areas based on the ring-shaped safety zone. It can be explained that the interval area is a transition space between installation areas, and defining its range can provide a reference for the surrounding location of the faulty device. Furthermore, the server can define the interval areas on both sides of the stand-alone alarm devices with fault attributes as identification areas. Here, since the identification area is directly adjacent to the installation area of ​​the faulty device, marking the identification area can form the positioning anchor point of the faulty device in the top view of the oil tank, avoiding the problem of ambiguity that may occur if only the installation area of ​​the faulty device is marked, allowing the management end to quickly locate the approximate range of the faulty device through the identification area. Finally, the server can generate fault identifiers based on the identified areas to point to independent alarm devices. These fault identifiers can be designed as visual elements such as arrows pointing towards the installation area of ​​the faulty device or highlighted borders. One end is associated with the identified area, and the other end precisely points to the independent alarm device with fault attributes, achieving an intuitive association. The top view of the oil tank containing this fault identifier is designated as the fault indication diagram and sent to the management terminal for display. Based on the clear fault identifiers, the management terminal can quickly locate the specific location of the faulty device through the relationship between the identified area and the pointing, without having to check each device one by one. At the same time, it clarifies the criteria for determining the faulty device, provides maintenance personnel with precise maintenance directions, significantly shortens the fault investigation and maintenance time, ensures that the faulty device is restored to normal operation as soon as possible, reduces the duration of monitoring blind spots, and effectively improves the timeliness of oil storage tank fire alarms.

[0048] In summary, this embodiment effectively solves the technical problems of alarm lag, unreasonable equipment layout, and difficulty in fault location in the traditional mode, significantly improving the accuracy, timeliness, and reliability of oil tank fire alarms, and providing intelligent technical support for oil tank safety protection. Specifically, this can be reflected in the following: 1. This embodiment divides the installation area circumferentially based on the top view of the oil tank and the height of the oil surface. It can realize the targeted layout of independent alarm devices, which can abandon the blindness of traditional random deployment or fixed point installation. The installation points are planned only in the idle area of ​​the oil tank and evenly distributed circumferentially. This ensures that there are no blind spots in high-risk areas such as the sealing ring at the top of the oil tank. At the same time, it can accurately reach the top area of ​​the tank that is difficult for humans to reach by means of robots, avoiding the positional deviation of manual installation. This allows each independent alarm device to cover the preset monitoring range. From the hardware layout level, it lays the foundation for alarm accuracy and solves the technical problems of missed monitoring in key areas and many false alarms in redundant areas caused by the lack of scientific planning in the installation of traditional equipment. 2. This embodiment does not require regular personnel inspections. The equipment can continuously monitor fire-related parameters such as leaked gas concentration and ambient temperature 24 hours a day. It can quickly respond to parameter changes caused by initial minor fires. Furthermore, when the alarm value exceeds the preset threshold, it does not only output a simple alarm signal, but also constructs a fire prediction map based on the top view of the oil tank. That is, the specific location of the stand-alone alarm device is clearly identified through a visual chart, which indirectly locks the fire hazard area and the possible spread trend, providing precise handling guidance for maintenance personnel and greatly reducing the risk of alarm lag. 3. This embodiment links fault detection with fault indication diagrams, enabling rapid location and timely handling of faulty equipment. Specifically, it allows for real-time fault detection of each independent alarm device. Once a fault is detected, a fault indication diagram is immediately generated based on the top view of the oil tank, clearly marking the installation area and location of the faulty device. This solves the technical problem of difficulty in locating faults in traditional wireless independent alarm devices. Maintenance personnel no longer need to check each device individually; they can directly and accurately locate the faulty device for repair or replacement based on the indication diagram, preventing long-term failure of faulty equipment and the formation of monitoring blind spots. Furthermore, the distinct display of fault indications and fire alarms prevents misjudgments or omissions due to equipment malfunctions, ensuring the overall reliability of the alarm system and further improving the accuracy of fire alarms.

[0049] Figure 2 The diagram illustrates the principle of fire early warning in this embodiment. It can be further explained that, as shown... Figure 2 As shown, its specific operating principle is as follows: At the secondary seal on the top of each storage tank, a wireless temperature probe (i.e., an independent alarm device in this embodiment) can be installed every 2 meters. It should be noted that the number of independent alarm devices is related to the size of the oil storage tank; for example, for a 100,000m³ tank... 3 The storage tank can be installed with up to 100 points, and each probe has a unique identifier. Wireless temperature probes within the same tank group can use technologies such as LoRa as the transmission method and form a star subnet with the receiving gateway. The receiving gateway can be installed in the control room closest to the tank group. It is mainly responsible for receiving temperature monitoring signals and alarm signals from all transmitters within the tank group. After being converted by optical fiber, the temperature monitoring signals and alarm signals can be transmitted to the host computer in the fire central control room via optical fiber. Furthermore, through the software platform, temperature and other data can be recorded and pushed via web pages, mobile apps, SMS, etc., and real-time data sharing with the fire department can be achieved to establish a rapid fire response mechanism and realize the detection of the temperature of the storage tank top and the alarm linkage in case of fire.

[0050] Furthermore, in this embodiment, it can be explained that the wireless temperature probe consists of a 32-bit low-power MCU, a PT1000 temperature probe, and a Lora wireless module. It can combine specific functions such as temperature acquisition, wireless transmission, status self-diagnosis, and remote control, and uses a built-in power supply battery to achieve the corresponding power supply mode, with an ultra-low power consumption design.

[0051] Furthermore, a multi-channel wireless transceiver terminal can consist of two independent, parallel-operating circuit boards. Each circuit board can have its own microcontroller and LoRa chip, and the two circuit boards use different LoRa channels. One board is responsible for receiving temperature data, while the other is responsible for sending remote control commands to the wireless temperature probe. The wireless transceiver terminal forwards data to the host server via a USB interface.

[0052] Figure 3 A schematic diagram of a stand-alone alarm device according to another embodiment of the present invention is shown, wherein, as Figure 3 As shown, the device includes: Equipment housing; and A cover located at the top of the equipment housing for sealing the equipment housing; The device housing contains a temperature sensing unit, a processing unit that executes the wireless fire intelligent alarm method as described in any one of claims 1-8, and a battery unit that powers the temperature sensing unit and the processing unit. The processing unit is connected to a communication antenna, and the sensing probe corresponding to the temperature sensing unit extends out of the housing cover.

[0053] It should be noted that the top of the device housing has a hollow structure, allowing the sensing probe of the temperature sensing unit to extend out of the housing cover. Since the processing unit and battery unit are located inside the device housing, therefore... Figure 3 Not shown.

[0054] Specifically, the stand-alone alarm device involved in this embodiment adopts a low-power mode of periodic pulse current operation. When not in use, the circuit is in sleep mode, with a sleep current ≤6uA. When sampling or data transmission is required, it wakes up from sleep mode and enters working mode, with a voltage not exceeding 3.6V and a maximum instantaneous transmission current of only 130mA, essentially not meeting the conditions for electrostatic spark generation. This meets the explosion-proof requirements for Exia IIB-T4 Ga intrinsically safe devices in GB3836.1-2010 Explosive Atmospheres Part 1: General Requirements for Equipment, GB3836.4-2010 Explosive Atmospheres Part 4: Equipment Protected by Intrinsic Safety "i", and GB3836.20-2010 Explosive Atmospheres Part 20: Equipment with an EPL of Ga.

[0055] Simultaneously, thionyl chloride batteries are used as the power supply. Due to the special chemical properties of thionyl chloride batteries and the fact that the filler is a non-flammable material with low activity, they can operate at very high temperatures, with an annual self-discharge current of less than 1%, a storage life of more than 10 years, and can even operate within a range of -50 to 150°C. This meets the requirements for explosion-proof battery equipment.

[0056] Therefore, the overall equipment meets the following intrinsically safe explosion-proof requirements at the circuit level. The enclosure provides waterproof and dustproof protection to ensure normal circuit operation.

[0057] The outer casing achieves its protective performance in the following ways: The entire housing is an intrinsically safe, explosion-proof cast aluminum enclosure. Except for the probe and antenna leads, the circuitry is completely sealed. An O-ring seal is used at the connection between the top and bottom housings, and the interior is filled with high-temperature resistant resin.
