Description

Technical Field

[0001] The present application relates to the field of fire management technology, and in particular to a cable trench zoning management method, system, storage medium and electronic equipment. Background Art

[0002] Cable trench is an underground passage or trench structure used to lay and protect various types of cables such as power cables and communication cables. However, the concentrated distribution of a large number of cables brings certain fire hazards, so effective fire prevention monitoring and management of cable trenches is crucial.

[0003] In related technologies, the cables in the cable trench are usually managed uniformly by average segmentation. The specific method is to divide the cable trench into multiple management sections according to a certain length, and each section is further divided into several fire protection zones. A zone control cabinet is set in each fire protection zone to monitor the environmental parameters and cable status in the area and take corresponding fire prevention measures when abnormalities occur. However, in practice, due to the complex environmental conditions of each section along the cable trench, the average segmentation method leads to a low utilization rate of the control cabinet, making the fire management plan for the cable trench not sophisticated enough. Summary of the invention

[0004] The present application provides a cable trench zoning management method, system, storage medium and electronic equipment, which can improve the utilization rate of control cabinets and provide a refined fire management plan for cable trenches.

[0005] In a first aspect, the present application provides a cable trench zoning management method, the method comprising: Calculate the fire risk values ​​of multiple sampling points in the cable trench and generate a fire risk polyline corresponding to the cable trench; Dividing the cable trench into a plurality of sections to be managed according to the fire risk polyline, wherein the fire partitions in the sections to be managed are provided with partition control cabinets; According to the fire risk type of the section to be managed, the partition control cabinet is controlled to execute the fire management plan corresponding to the fire risk type.

[0006] By adopting the above technical solution, the sections to be managed can be scientifically and reasonably divided according to the actual distribution of fire risks, avoiding the problem of inaccurate section division in the traditional zoning method. By calculating the fire risk polyline and combining it with the management capability of the partition control cabinet, dynamic adjustment of the sections to be managed is achieved, so that the risk level of each section can match the control capability of the control cabinet, thereby improving the utilization rate of the control cabinet. According to the specific fire risk type of different sections to be managed, personalized fire management solutions are automatically configured for the corresponding partition control cabinet. Compared with the unified management strategy in the prior art, a more refined fire management solution can be provided.

[0007] Optionally, the calculating of the fire risk values ​​of the plurality of sampling points in the cable trench includes: Obtain soil information, spatial information, cable density information, cable position relationship information and oxygen ratio information of sampling points in the cable trench; The soil information, the space information, the cable density information, the cable position relationship information and the oxygen ratio information are weighted and summed to obtain the fire risk value of the sampling point.

[0008] By adopting the above technical solution, the fire risk value calculated by weighted summation can comprehensively evaluate the potential fire hazard level of each sampling point by comprehensively considering the above multiple information. Compared with considering only a single factor such as temperature and current, this multi-parameter comprehensive evaluation method is more comprehensive and scientific, and can more accurately reflect the actual risk level.

[0009] Optionally, calculating the fire risk values ​​of multiple sampling points in the cable trench to generate a fire risk polyline corresponding to the cable trench includes: Calculating fire risk values ​​of multiple sampling points in the cable trench, and calculating a first difference between the fire risk values ​​of adjacent sampling points; Determine whether the first difference is greater than a preset first threshold; If the first difference is greater than the first threshold, setting a first sampling point between adjacent sampling points, and calculating a first fire risk value corresponding to the first sampling point; A fire risk polyline corresponding to the cable trench is generated according to the fire risk value and the first fire risk value.

[0010] By adopting the above technical solution, by analyzing the differences in fire risk values ​​of adjacent sampling points, new sampling points are added in areas with significant risk changes, thereby improving the precision and accuracy of the fire risk polyline generated in the end. This approach of dynamically adjusting the sampling density makes the polyline more consistent with the actual risk distribution.

[0011] Optionally, dividing the cable trench into a plurality of sections to be managed according to the fire risk polyline includes: Calculate the integral value of the fire risk polyline on the horizontal axis to obtain the integral area corresponding to the length of the cable trench; The cable trench is divided into a plurality of sections to be managed according to the integrated area.

[0012] By adopting the above technical solution, the integral area comprehensively reflects the cumulative fire risk level along the cable trench, which can more comprehensively measure the overall risk status of a section of the area compared to considering only the risk value of a certain point. The segment division based on the integral area can ensure that the risk level of each section to be managed is relatively balanced, avoiding the problem of unreasonable division of high and low risk areas that may be caused by the traditional equidistant division method.

[0013] Optionally, dividing the cable trench into a plurality of sections to be managed according to the integrated area includes: Acquire the configuration parameters of the partition control cabinet and determine the standard management area of ​​the partition control cabinet; Obtaining the peak point of the fire risk polyline; The length of the cable trench is laterally extended with the peak point as the starting center point until the integral area meets the standard management area, and the section where the integral area meets the preset standard management area is determined as the section to be managed.

[0014] By adopting the above technical solution, the standard management area is first determined based on the actual configuration parameters of the partition control cabinet, ensuring the scientific nature and operability of the division, so that each section to be managed can match the management capacity of the control cabinet. Secondly, by identifying the peak point of the fire risk polyline, the high-risk area is accurately located, providing a key reference point for section division. With the peak point as the starting center point for horizontal expansion, the management needs of high-risk areas are given priority, effectively improving the pertinence of resource allocation. At the same time, the integral area is matched with the standard management area to ensure that the risk level of each section to be managed can be fully controlled. This dynamically adjusted division method not only takes into account the actual situation of risk distribution, but also takes into account the capacity limitations of management equipment, thereby realizing the refinement and personalization of cable trench zoning management.

[0015] Optionally, before the step of horizontally extending the length of the cable trench with the peak point as the starting center point, the step further includes: Obtaining the slopes on both sides of the peak point; The expansion rate when the length of the cable trench is expanded laterally is determined according to the slope.

[0016] By adopting the above technical solution, the method of determining the expansion rate based on the slope introduces an adaptive mechanism, so that the segment division process can be flexibly adjusted according to the specific situation of the risk distribution. In areas where the risk changes more drastically (larger slope), the system will adopt a slower expansion rate to ensure that high-risk areas can be more finely divided and managed; while in areas where the risk changes relatively slowly (smaller slope), a faster expansion rate can be used to improve the division efficiency. This slope-based dynamic expansion method not only improves the accuracy of the division of the sections to be managed, but also optimizes resource allocation, so that limited management resources can be more reasonably allocated to areas with different risk characteristics.

[0017] Optionally, controlling the partition control cabinet to execute a fire management plan corresponding to the fire risk type according to the fire risk type of the section to be managed includes: If the fire risk type is a cable fault fire risk type, a first fire management plan corresponding to the cable fault fire risk type is generated, and the partition controller is controlled to execute the first fire management plan, wherein the first fire management plan is used to improve the monitoring intensity of the cables in the area to be managed; or, If the fire risk type is an external interference fire risk type, a second fire management plan corresponding to the external interference fire risk type is generated, and the partition controller is controlled to execute the second fire management plan, wherein the second fire management plan is used to increase the monitoring intensity of the environment in the area to be managed.

[0018] By adopting the above technical solutions, the two main types of fire risks, cable failure and external interference, are distinguished, providing a clear classification basis for risk management. For the cable failure fire risk type, the system generates the first fire management plan, focusing on improving the monitoring intensity of cables in the management area; and for the external interference fire risk type, the system generates the second fire management plan, focusing on improving the monitoring intensity of the environment in the management area. This differentiated management strategy enables the system to respond to fire risks from different sources in a targeted manner, improving the accuracy and efficiency of risk management.

[0019] In a second aspect, the present application provides a cable trench partition management system, the system comprising: A risk polyline generation module is used to calculate the fire risk values ​​of multiple sampling points in the cable trench and generate a fire risk polyline corresponding to the cable trench; A section division module, used for dividing the cable trench into a plurality of sections to be managed according to the fire risk polyline, wherein the fire partitions in the sections to be managed are provided with partition control cabinets; The management module is used to control the partition control cabinet to execute the fire management plan corresponding to the fire risk type according to the fire risk type of the section to be managed.

[0020] In a third aspect, the present application provides a computer storage medium, wherein the computer storage medium stores a plurality of instructions, wherein the instructions are suitable for being loaded by a processor and executing any one of the above methods.

[0021] In a fourth aspect, the present application provides an electronic device, comprising a processor, a memory and a transceiver, wherein the memory is used to store instructions, the transceiver is used to communicate with other devices, and the processor is used to execute the instructions stored in the memory so that the electronic device performs any one of the methods described above.

[0022] In summary, the beneficial effects brought about by the technical solution of this application include: By adopting the above technical solution, the sections to be managed can be scientifically and reasonably divided according to the actual distribution of fire risks, avoiding the problem of inaccurate section division in the traditional zoning method. By calculating the fire risk polyline and combining it with the management capability of the partition control cabinet, dynamic adjustment of the sections to be managed is achieved, so that the risk level of each section can match the control capability of the control cabinet, thereby improving the utilization rate of the control cabinet. According to the specific fire risk type of different sections to be managed, personalized fire management solutions are automatically configured for the corresponding partition control cabinet. Compared with the unified management strategy in the prior art, a more refined fire management solution can be provided. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] See also Figure 1 , is a flow chart of a cable trench zoning management method provided in an embodiment of the present application. The method can be implemented by a computer program, can be implemented by a single-chip microcomputer, or can be run on a cable trench zoning management system based on the von Neumann system. The computer program can be integrated into an application or run as an independent tool application. The specific steps of the cable trench zoning management method are described in detail below.

[0029] S101: Calculate the fire risk values ​​of multiple sampling points in the cable trench and generate a fire risk polyline corresponding to the cable trench.

[0030] The cable trench refers to an underground passage or trench structure used to lay and protect various types of cables such as power cables, communication cables, etc. In the embodiment of the present application, it can be understood as a linearly extended closed or semi-closed space for accommodating, supporting and protecting a large number of cables.

[0031] Among them, the fire risk value refers to a numerical indicator used to quantitatively assess the possibility and potential degree of harm of a fire at a specific location or area. In the embodiment of the present application, it can be understood as a comprehensive representation of the probability and severity of a fire at a specific sampling point in the cable trench. This is a comprehensive value obtained by considering multiple factors, reflecting the degree of fire risk at the location corresponding to the sampling point.

[0032] Among them, the fire risk polyline refers to a graphical representation method used to intuitively display the fire risk distribution of the cable trench along its length. In the embodiment of the present application, it can be understood as a polyline graph formed by connecting the fire risk values ​​of multiple sampling points in the cable trench. This polyline represents the length or distance of the cable trench on the horizontal axis, and the vertical axis represents the fire risk value of the corresponding position. The fire risk polyline is used to intuitively present the fire risk status of each part of the cable trench, help identify high-risk areas, and provide a basis for the zoning management of the cable trench.

[0033] In this embodiment, first, multiple sampling points are selected along the length direction of the cable trench, and the intervals between these sampling points can be determined according to the actual situation and management requirements of the cable trench. For each sampling point, multiple parameters including soil information, spatial information, cable density information, cable position relationship information, and oxygen ratio information are collected. The fire risk value of each sampling point is then obtained based on these parameters. Finally, the fire risk values ​​of all sampling points are connected in order of their positions in the cable trench to form a continuous fire risk broken line. The horizontal coordinate of this broken line represents the length of the cable trench, and the vertical coordinate represents the fire risk value at the corresponding position. The fire risk broken line generated by this method can intuitively display the fire risk distribution of each part of the cable trench, and clearly reflect the high and low changes and trends of the risk. This provides an important basis for subsequent zoning management, enabling managers to quickly identify high-risk areas, reasonably divide management sections, and formulate targeted fire prevention and response measures.

[0034] Based on the above embodiment, as an optional implementation, calculating the fire risk values ​​of multiple sampling points in the cable trench can be implemented by the following steps S201-S202.

[0035] S201: Obtain soil information, spatial information, cable density information, cable position relationship information, and oxygen ratio information of sampling points in the cable trench.

[0036] Among them, soil information refers to a series of parameters and data that describe the characteristics of the geological environment in which the cable trench is located. In the embodiment of the present application, it can be understood as a comprehensive characterization of the physical, chemical and mechanical properties of the soil or rock around the cable trench. Soil information is used to evaluate the stability, thermal conductivity and impact of the cable trench on the spread of fire, and is one of the important input parameters for calculating the fire risk value. Specifically, soil information may include soil type (such as sand, clay, rock, etc.), water content, density, porosity, thermal conductivity, resistivity and other characteristics. These characteristics directly affect the heat dissipation capacity, humidity and structural stability of the cable trench, thereby affecting the operating environment of the cable and the potential fire risk.

[0037] Among them, spatial information refers to a data set that describes the geometric characteristics and spatial layout of the cable trench and its internal structure. In the embodiment of the present application, it can be understood as a detailed description of the size, shape, direction and internal space utilization of the cable trench. Spatial information is used to evaluate factors such as the ventilation conditions, heat accumulation, fire spread path and fire extinguishing difficulty of the cable trench, and is one of the key input parameters for calculating the fire risk value. Specifically, spatial information may include geometric parameters such as the length, width, depth, cross-sectional shape, slope, turning angle of the cable trench, and the distribution of the internal space, such as the location, number of layers and spacing of the cable rack, the size and distribution of the vents, the width of the maintenance passage, etc. This information directly affects the air circulation, heat dissipation and possible paths of fire spread inside the cable trench. For example, a narrow or curved cable trench may cause heat accumulation and local changes in oxygen concentration, increasing the risk of fire; while reasonably set vents and sufficiently spacious maintenance passages may reduce the risk.

[0038] Among them, the cable density information refers to a data indicator that describes the concentration of cable distribution in the cable trench. In the embodiment of the present application, it can be understood as a quantitative representation of the number, total cross-sectional area or total weight of cables in a unit space. Specifically, the cable density information may include the number of cables per meter in length, the sum of the cable cross-sectional areas per unit area, the weight of cables per unit volume, etc. Areas with high cable density generally mean a higher risk of fire, because it not only provides more combustible materials, but also may lead to heat accumulation and difficulty in heat dissipation. For example, densely arranged cables may hinder air circulation and increase the risk of local overheating; at the same time, when a fire occurs, high-density areas may produce more intense fires and spread faster.

[0039] Among them, the cable position relationship information refers to a data set that describes the relative spatial layout and distance between the cables in the cable trench. In the embodiment of the present application, it can be understood as a detailed description of the spacing between cables, the hierarchical distribution, and the relative position relationship with the cable trench wall and other structures. Specifically, the cable position relationship information may include the minimum spacing between cables, the distance between the cables and the trench wall, the number of layers of cables on the rack and the arrangement of each layer, the relative positions of different types of cables (such as high-voltage and low-voltage cables), etc. This information directly affects the heat distribution and transfer efficiency in the cable trench, as well as the propagation path of potential fires. For example, closely arranged cables may cause local heat accumulation and increase the risk of overheating; and the mixed arrangement of different types of cables may affect the starting point and spread speed of the fire.

[0040] Among them, the oxygen ratio information refers to a data indicator that describes the oxygen content in the air in the cable trench. In the embodiment of the present application, it can be understood as a quantitative representation of the oxygen concentration in the air at different positions and time points in the cable trench. Specifically, the oxygen ratio information may include the percentage of oxygen concentration at each sampling point in the cable trench, the time variation trend of oxygen concentration, and the comparison value with the standard atmospheric oxygen content. This information directly reflects the ventilation conditions and potential fire risks inside the cable trench. Oxygen is a necessary element to support combustion, and its concentration directly affects the probability of fire and the intensity of combustion. For example, a low oxygen environment may reduce the risk of fire, but it may also cause accelerated aging of cable insulation materials; while a high oxygen environment may increase the probability of fire and the severity of the fire.

[0041] In specific implementation, multiple sampling points are first selected along the length of the cable trench. The intervals between these sampling points can be determined according to the actual length and complexity of the cable trench. Usually, a sampling point can be set every 10-50 meters. The density of sampling points can be appropriately increased in areas with large changes in cable density or complex spatial structures. For each sampling point, a variety of methods and equipment are used to collect the required information.

[0042] Soil quality information can be obtained by measuring soil type, water content, density and other parameters through soil sampling and analysis, geological radar detection and other methods. Spatial information can be obtained by measuring the geometric size, shape and internal structure layout of the cable trench using equipment such as laser rangefinders and 3D scanners. Cable density information can be obtained by calculating the number of cables or total cross-sectional area per unit space through on-site surveys and cable wiring diagrams. Cable position relationship information can be obtained by recording the relative position and spacing between cables with the help of high-precision cameras or 3D modeling technology. Oxygen ratio information can be obtained by sampling and measuring at different locations and time points using portable gas analyzers.

[0043] This comprehensive data collection method can provide detailed information on all aspects of the cable trench, thereby achieving comprehensive coverage of factors affecting fire risk. Soil information reflects the geological environment characteristics of the cable trench, affecting heat conduction and structural stability; spatial information describes the geometric characteristics of the cable trench, determining ventilation conditions and fire spread paths; cable density information and position relationship information together reflect the distribution of combustibles and potential hot spots; and oxygen ratio information is directly related to the occurrence and development conditions of fire.

[0044] S202: Perform weighted summation on soil quality information, space information, cable density information, cable position relationship information, and oxygen ratio information to obtain a fire risk value of the sampling point.

[0045] When it comes to specific implementation, it is first necessary to standardize the information to ensure that different types of data can be compared and calculated on the same scale. This can be achieved by converting each piece of information into a standardized score within a unified range, where a lower score indicates that the factor has a smaller impact on the fire risk and a higher score indicates a greater impact. The standardization process takes into account the characteristics of each piece of information and the potential impact on the fire risk.

[0046] Next, weights are assigned to each factor based on its relative importance to fire risk. The assignment of weights is a critical step that reflects the importance of different factors in fire risk assessment. This process can be determined based on expert experience, historical data analysis, or the results of machine learning models. For example, cable density information and oxygen ratio information may have a more direct impact on fire risk than soil quality information, so higher weights can be given.

[0047] Finally, by multiplying each standardized information by its corresponding weight and adding up all the results, a comprehensive fire risk value is obtained. This risk value is a single value that represents the fire risk level of the sampling point after taking all factors into consideration.

[0048] Based on the above embodiment, as an optional implementation, in order to improve the accuracy of the fire risk polyline, that is, whether the spacing of the sampling points is accurately selected, the following steps S301-S304 may be adopted.

[0049] S301: Calculate fire risk values ​​of multiple sampling points in the cable trench, and calculate a first difference in fire risk values ​​of adjacent sampling points.

[0050] The first difference refers to the degree of difference in the fire risk values ​​between two adjacent sampling points. In the embodiment of the present application, it can be understood as the numerical difference between the fire risk values ​​of adjacent sampling points obtained by calculation, and this difference reflects the spatial variation trend of the fire risk of the cable trench. Specifically, the first difference can be obtained by calculating the absolute value of the difference between the fire risk values ​​of two adjacent sampling points. The larger this value is, the more significant the change in fire risk between two adjacent sampling points; conversely, the smaller the value is, the more stable the fire risk in the adjacent area is.

[0051] In specific implementation, the absolute value of the difference between the fire risk values ​​of two adjacent sampling points is calculated according to the spatial order of the sampling points, which is the first difference. This process requires traversing all adjacent pairs of sampling points to obtain a series of first differences. The significance of calculating the first difference is to reveal the spatial variation characteristics of the fire risk of the cable trench. A larger first difference indicates that there are significant differences in the fire risks of adjacent areas, which may be potential boundaries of different risk level partitions; while a smaller first difference indicates that the fire risks of adjacent areas are relatively consistent and may belong to the same risk level area. By analyzing the distribution of the first difference, areas with drastic risk changes can be identified.

[0052] S302: Determine whether the first difference is greater than a preset first threshold.

[0053] In specific implementation, it is first necessary to determine a suitable preset first threshold. The preset first threshold can be determined based on historical data analysis, expert experience judgment, or statistical methods. In practical applications, it may be necessary to find the threshold that best suits a specific cable trench environment through repeated trials and adjustments.

[0054] After determining the preset first threshold, the calculated first difference of each pair of adjacent sampling points is compared with the threshold. If the first difference is greater than the preset first threshold, it is determined that there is a significant change in fire risk between the pair of adjacent sampling points; conversely, if the first difference is less than or equal to the preset first threshold, it is considered that the change in fire risk between the pair of adjacent sampling points is not significant.

[0055] S303: If the first difference is greater than the first threshold, a first sampling point is set between adjacent sampling points, and a first fire risk value corresponding to the first sampling point is calculated.

[0056] The first sampling point refers to a newly set sampling point between two adjacent sampling points whose first difference is greater than a preset first threshold. In the embodiment of the present application, it can be understood as an additional new risk assessment position in the area identified as having significant risk changes in the cable trench. The first sampling point is used to improve the sampling accuracy of the area with significant risk changes.

[0057] The first fire risk value refers to the fire risk value calculated for the newly set first sampling point. In the embodiment of the present application, it can be understood that when the first difference between two adjacent sampling points is greater than the preset first threshold, the fire risk level of the newly added first sampling point is evaluated. The first fire risk value is used to provide more detailed risk distribution information, enhance the accuracy of risk assessment and the precision of zoning management.

[0058] In this embodiment, the system compares the first difference of each pair of adjacent sampling points with a preset first threshold. When it is found that the first difference exceeds the first threshold, it indicates that there is a significant risk change between the two sampling points. At this time, the system will add a new sampling point between the two sampling points, namely the first sampling point. The position of the first sampling point can be set in the middle of the two original sampling points, or it can be adjusted according to the specific situation. After setting the first sampling point, the system will immediately perform a fire risk assessment on the newly added sampling point and calculate the corresponding first fire risk value.

[0059] S304: Generate a fire risk polyline corresponding to the cable trench according to the fire risk value and the first fire risk value.

[0060] First, the system collects the fire risk values ​​of all the original sampling points and the first fire risk values ​​of the first sampling points added in the area where the risk changes significantly. Then, these data points are arranged in the order of their spatial positions in the cable trench. For each data point, its horizontal axis represents the position in the cable trench (which can be the distance from the starting point of the cable trench), and the vertical axis represents the corresponding fire risk value or the first fire risk value. Next, the system connects these data points in their spatial order to form a polyline. This polyline is the fire risk polyline of the cable trench.

[0061] S102: Divide the cable trench into a plurality of sections to be managed according to the fire risk polyline, and set a partition control cabinet in the fire partition within the section to be managed.

[0062] The section to be managed refers to an independent management unit divided in the cable trench. In the embodiment of the present application, it can be understood that the cable trench is divided into several continuous sections, each section is equipped with a partition control cabinet for independent management. The section to be managed is used to realize the partition management of the cable trench, improve the management efficiency and system reliability.

[0063] Among them, the fire partition in the section to be managed refers to a blocked area in the cable trench. In the embodiment of the present application, it can be understood as the cable trench area between two adjacent blocking devices in a section to be managed. Fire partitions are used to achieve refined fire management and control of cable trenches. Specifically, fire partitions are divided by installing blocking devices in the cable trench. The area between every two adjacent blocking devices is defined as a fire partition. This division method ensures that each fire partition is a relatively independent and controllable unit.

[0064] The partition control cabinet refers to an intelligent control device installed in the fire partition of the cable trench. In the embodiment of the present application, it can be understood as a dedicated control device set in each fire partition for managing and controlling the partition. The partition control cabinet is used to receive various alarm signals in the fire partition and send corresponding control instructions to achieve real-time monitoring and intelligent management of specific areas of the cable trench.

[0065] In this embodiment, areas with higher risks and areas with relatively lower risks can be identified based on the trend of the fire risk polyline. In areas with higher risks, smaller sections to be managed can be set to achieve more refined management; while in areas with lower risks, the scope of the sections to be managed can be appropriately expanded. This risk-based segment division method can optimize resource allocation and concentrate limited management resources where they are most needed. After determining the sections to be managed, each section to be managed is further divided into several fire partitions. The division of fire partitions is usually based on physical blocking devices, and the area between every two adjacent blocking devices is defined as a fire partition.

[0066] In each fire partition, a partition control cabinet is set up. As the core management device of the fire partition, the partition control cabinet is responsible for receiving alarm signals from various sensors and monitoring equipment in the area and sending corresponding control instructions. This setting makes each fire partition a relatively independent management unit, which can quickly respond to and handle local problems while keeping in touch with the entire cable trench management system.

[0067] Based on the above embodiment, as an optional implementation, step S102 also includes S401-S102.

[0068] S401: Calculate the integral value of the fire risk polyline on the horizontal axis to obtain the integral area corresponding to the length of the cable trench.

[0069] Among them, the integral area refers to the area of ​​the region enclosed by the curve and the coordinate axis in the coordinate system. In the embodiment of the present application, it can be understood as the area of ​​the closed area formed between the broken line and the horizontal axis in the fire risk line graph. The integral area is used to quantitatively evaluate the cumulative fire risk level in a specific section of the cable trench and provide data support for management decisions. In the context of cable trench fire risk management, the concept of integral area is innovatively applied to risk assessment. The horizontal axis of the fire risk line graph usually represents the length or position of the cable trench, and the vertical axis represents the fire risk level at the corresponding position. Therefore, the area between the bottom of the broken line and the horizontal axis not only reflects the risk level of a certain point, but also represents the cumulative risk in a section of the area. The calculation of the integral area can be achieved by numerical integration methods, such as the trapezoidal method or the Simpson method. This method converts the continuous risk distribution into a quantifiable value, so that the risk levels of different sections can be directly compared.

[0070] In specific implementation, it is first necessary to determine the interval of integration, that is, the position of the starting point and the end point of the cable trench on the horizontal axis. Then, a numerical integration method, such as the trapezoidal method or the Simpson method, can be used to calculate the area under the fire risk polyline. Taking the trapezoidal method as an example, the length of the cable trench can be divided into several small intervals of equal length, and the risk value of each small interval can be approximated as the average of the risk values ​​of its two end points. By calculating the area of ​​each small interval and summing them up, the integral area corresponding to the length of the entire cable trench can be obtained. In actual operation, a computer program can be used to implement this calculation process. First, the data points of the fire risk polyline are entered into the program, and then the integral interval and division accuracy are set. The program will automatically calculate the area of ​​each small interval and accumulate them to obtain the total integral area.

[0071] S402: Divide the cable trench into a plurality of sections to be managed according to the integrated area.

[0072] In this embodiment, the standard integral area value corresponding to the partition control cabinet is used as the basis for division. This method combines the quantitative risk assessment results with the actual management equipment to achieve a more accurate and practical segment division.

[0073] Each partition control cabinet has an upper limit of its management capacity, which can be quantified by the standard integral area value. The standard integral area value actually represents the maximum risk level that a partition control cabinet can effectively manage. In this way, it can be ensured that each section to be managed has a management capacity that matches its risk level.

[0074] In specific implementation, it is first necessary to determine the standard integral area value corresponding to the partition control cabinet. This value is usually determined based on the technical parameters, management capabilities and actual operating experience of the partition control cabinet. Factors that may need to be considered include the signal processing capabilities of the control cabinet, the number of connected sensors, response time, etc. Once this standard value is determined, the cumulative integral area can be calculated along the length of the cable trench. Starting from the starting point of the cable trench, the integral area is accumulated along the fire risk polyline. When the accumulated integral area reaches or exceeds the standard integral area value for the first time, the point is marked as the end point of a section to be managed and the starting point of the next section to be managed. Set up a partition control cabinet at this dividing point. Then, reset the cumulative area to zero, continue to calculate forward, and repeat this process until the entire length of the cable trench is processed.

[0075] Based on the above embodiment, as an optional implementation, step S402 also includes S501-S503.

[0076] S501: Acquire the configuration parameters of the partition control cabinet and determine the standard management area of ​​the partition control cabinet.

[0077] Among them, the configuration parameters of the partition control cabinet refer to a series of technical indicators and set values ​​used to describe and set the functional characteristics and operating status of the partition control cabinet. In the embodiment of the present application, it can be understood as a set of key parameters of the control cabinet that are directly related to the cable trench fire risk management. These parameters are used to optimize the performance of the partition control cabinet so that it can effectively manage and monitor the fire risk of the cable trench section to be managed.

[0078] The standard management area refers to a benchmark value used to quantify the management capability of the partition control cabinet, which reflects the risk level of the cable trench area that can be effectively managed by a single partition control cabinet under ideal conditions. In the embodiment of the present application, it can be understood as an integral area value corresponding to the configuration parameters of the partition control cabinet, which represents the maximum risk area that the control cabinet can effectively monitor and manage under its standard configuration.

[0079] In the cable trench fire risk management system, obtaining the configuration parameters of the partition control cabinet and determining its standard management area is a key step, which directly affects the subsequent segmentation and risk management effect. The implementation of this step begins with the comprehensive collection and analysis of various configuration parameters of the partition control cabinet, including but not limited to signal processing capability, the number of connectable sensors, response time, data storage capacity, communication protocol, backup power supply capacity, etc. The purpose of collecting these parameters is to fully understand the performance characteristics and management capabilities of the partition control cabinet and provide a basis for determining the standard management area. In specific implementation, it is necessary to establish a mathematical model to quantify the relationship between the various configuration parameters of the partition control cabinet and its management capability. This model may involve complex algorithms and needs to consider the mutual influence and weight between parameters. For example, signal processing capability and the number of connectable sensors may have a greater impact on the standard management area, while the backup power supply capacity may have a smaller impact. Secondly, it is necessary to appropriately adjust and calibrate the model in combination with the actual situation of the cable trench, such as environmental conditions, risk distribution characteristics, etc. This may involve field testing and historical data analysis to ensure the accuracy and applicability of the model.

[0080] S502: Obtain the peak point of the fire risk polyline.

[0081] In this embodiment, the fire risk polyline is drawn based on the risk factors at different locations along the cable trench, where the peak points represent the areas with the highest risk, which require special attention and key management. The purpose of obtaining these peak points is to accurately identify the most dangerous areas in the cable trench, thereby optimizing resource allocation and improving the overall risk management effect. This is achieved through numerical analysis methods, such as using derivative methods or local maximum search algorithms. Specifically, the system calculates the rate of change of the risk value point by point along the polyline, and when a point is found where the risk value changes from increasing to decreasing, it can be identified as a peak point.

[0082] S503: Extend the length of the cable trench laterally with the peak point as the starting center point until the integrated area meets the standard management area, and determine the section whose integrated area meets the preset standard management area as the section to be managed.

[0083] The implementation starts with the identified peak point. The system will expand in both the left and right directions with this point as the center. During the expansion process, the system continues to calculate the accumulated integral area. The integral area here is the integral of the risk value over the distance, reflecting the overall risk level in a section of the area. The expansion process will continue until the accumulated integral area reaches or just exceeds the predetermined standard management area. This standard management area is calculated based on the configuration parameters of the partition control cabinet and represents the maximum risk area that the control cabinet can effectively manage under ideal conditions.

[0084] In actual operation, the system needs to consider the physical characteristics and environmental factors of the cable trench. For example, if the physical separation points of the cable trench (such as firewalls, corners, etc.) are encountered during the expansion process, it may be necessary to naturally divide the segment at these points. In addition, if another risk peak point is encountered during the expansion process, the system needs to evaluate whether to merge the two high-risk areas into one section to be managed, or to divide it between the two points. This decision may need to consider multiple factors, such as the distance between the two peak points, the difference in risk levels, etc.

[0085] In order to ensure the continuity and comprehensiveness of management, after determining a section to be managed, the system will continue to process the remaining undivided areas, and may select the next risk peak point as the new starting center point, repeating the above process until the entire cable trench is completely divided into multiple sections to be managed. In this process, it may happen that the integrated area of ​​the last section fails to fully reach the standard management area. In this case, the system can decide whether to merge it into the adjacent section or manage it as a separate small section according to actual needs.

[0086] Based on the above embodiment, as an optional implementation, before step S503, the method further includes obtaining the slopes on both sides of the peak point; and determining the expansion rate when the length of the cable trench is horizontally expanded according to the slope.

[0087] The specific implementation process first needs to calculate the slopes on both sides of the peak point. The system will select a certain range of data points on both sides of the peak point, and fit the local risk change curve through these data points. Then, the slopes on both sides of the peak point are calculated using numerical analysis methods (such as differential method or curve fitting method). These slopes reflect the rate of change of the risk value near the peak point. A larger slope indicates that the risk value changes rapidly, and a smaller slope indicates that the risk value changes slowly.

[0088] After obtaining the slope, the system will determine the rate of horizontal expansion according to the preset algorithm. Generally speaking, the larger the slope, the more drastic the change in risk value. At this time, the rate of horizontal expansion should be slower in order to more finely divide the high-risk area; on the contrary, when the slope is small, the risk value changes more slowly, and a faster expansion rate can be used. The specific expansion rate can be determined by a function that takes the slope as input and outputs the corresponding expansion step. For example, an inverse proportional function can be used to make the expansion rate inversely proportional to the slope.

[0089] S103: According to the fire risk type of the section to be managed, the partition control cabinet is controlled to execute the fire management plan corresponding to the fire risk type.

[0090] Among them, the disaster risk type refers to the classification and summary of various potential risk factors that may cause fires in cable trenches. In the embodiments of the present application, it can be understood as the result of systematic classification of risk sources that may cause fires based on multiple dimensions such as the internal environmental characteristics of the cable trench, the operating status of the cable, and external influencing factors. This classification covers a variety of situations that may cause fires, such as cable overheating, insulation aging, short circuit, arc discharge, accumulation of flammable gas, and intrusion of external fire sources.

[0091] Among them, the fire management plan refers to a comprehensive plan of prevention, monitoring, control and emergency measures formulated for the identified fire risk types and specific risk situations in the cable trench. In the embodiment of the present application, it can be understood as a set of systematic and standardized risk management strategies and specific implementation plans tailored for each section based on the risk assessment results of the cable trench fire risk management system for each section to be managed, combined with the characteristics of different fire risk types.

[0092] The fire management plan is used to regulate daily risk prevention work. According to the risk characteristics of different sections, the plan will specify in detail the frequency and content of regular inspections, the standards and procedures for equipment maintenance, and the control requirements for environmental parameters. For example, for sections with the risk of cable overheating, the plan may require more frequent temperature detection and load monitoring; for sections with the risk of flammable gas accumulation, it may emphasize regular inspection and maintenance of the ventilation system.

[0093] Secondly, the fire management plan is used to guide the configuration and operation of the real-time monitoring system. The plan will determine the key parameters that need to be monitored according to different risk types, set the corresponding alarm thresholds, and specify the response process for different levels of alarms. For example, for arc discharge risks, the plan may require the installation of special arc detectors and set lower alarm thresholds to ensure early detection of problems.

[0094] Thirdly, the fire management plan is used to formulate emergency response strategies. It will pre-set a series of emergency measures for different types and degrees of fire risks, including but not limited to the activation conditions of the automatic fire extinguishing system, personnel evacuation routes, emergency communication plans, etc. These plans can ensure that when a fire occurs, the system and personnel can respond quickly and orderly to minimize losses.

[0095] The specific implementation process first requires the system to determine the main fire risk types for each section to be managed based on the previous risk assessment results. This may include cable overheating, insulation aging, short circuits, arc discharges, flammable gas accumulation and other types. For each risk type, the system has pre-defined fire management plans. These plans include a series of specific implementation plans such as preventive measures, monitoring parameters, alarm thresholds, emergency response strategies, etc. for specific risk types.

[0096] After determining the risk type, the system sends corresponding control instructions to the partition control cabinet responsible for the section to be managed. These instructions activate the functional modules in the control cabinet that correspond to the specific fire management plan. For example, for a section with a risk of cable overheating, the control cabinet may be instructed to start more frequent temperature monitoring, adjust the temperature alarm threshold, and prepare emergency measures such as reducing the load or cutting off the power supply. For a section with a risk of flammable gas accumulation, the control cabinet may be instructed to strengthen the monitoring of gas concentration, adjust the operating parameters of the ventilation system, and prepare emergency exhaust and alarm triggering measures.

[0097] During the execution process, the partition control cabinet will continuously collect data from various sensors and conduct real-time analysis and judgment according to the preset fire management plan. If the monitored parameters exceed the preset threshold, the control cabinet will automatically execute the corresponding preventive or emergency measures according to the provisions of the plan. This may include starting local cooling devices, adjusting ventilation systems, triggering alarms, and even cutting off power when necessary.

[0098] Based on the above embodiment, as an optional implementation, step S103 may include S1031 or S1032.

[0099] S1031: If the fire risk type is a cable fault fire risk type, a first fire management plan corresponding to the cable fault fire risk type is generated, and the partition controller is controlled to execute the first fire management plan, where the first fire management plan is used to increase the monitoring intensity of the cables in the management area.

[0100] Among them, the cable fault fire risk type refers to the potential dangerous factors that may cause fires caused by faults or defects in the cable itself. In the embodiment of the present application, it can be understood as the result of systematic classification of cable faults that may cause fires based on factors such as the internal structure of the cable, material properties, operating status, and external environmental influences. This classification covers a variety of situations that may cause fires, such as line overload, insulation aging, manufacturing defects, installation damage, and joint failure. The cable fault fire risk type is used to provide a special assessment and management framework for cable problems itself for the cable trench fire risk management system. By clarifying different types of cable fault risks, the system can formulate monitoring strategies and preventive measures more specifically. For example, for the risk of line overload type, the system can focus on monitoring the load current and temperature changes of the cable; for the risk of insulation aging type, it may be necessary to combine factors such as the age of the cable and environmental humidity for a comprehensive assessment.

[0101] In actual applications, the system will configure corresponding monitoring equipment and parameters according to these cable fault fire risk types. For example, for cables that may have manufacturing defects or installation damage, the system may arrange more frequent partial discharge detection; for areas that may have joint failure risks, the frequency of infrared thermal imaging detection may be increased. Through this targeted monitoring, the system can detect potential cable faults earlier and take preventive measures in time.

[0102] Among them, the first fire management plan refers to a set of comprehensive prevention, monitoring and emergency measures formulated for specific cable fault fire risk types. In the embodiment of the present application, it can be understood as a set of systematic and intelligent risk management strategies formulated based on an in-depth analysis of the cable fault fire risk types, combined with the actual situation and operation requirements of the cable trench. This set of strategies includes specific operations and processes in multiple aspects such as risk assessment, real-time monitoring, early warning threshold setting, automated control measures, and emergency response. The first fire management plan is used to guide the partition control cabinet to accurately manage the cables in a specific area to minimize the risk of fire. It dynamically adjusts the management strategy by integrating various monitoring data to achieve timely identification and effective prevention of potential fire risks. For example, for areas where there is a risk of line overload, the plan may include a series of measures such as setting multi-level load warning values, real-time monitoring of temperature changes, automatic adjustment of heat dissipation equipment, and reducing loads or switching to backup lines when necessary.

[0103] In specific implementation, when the fire risk type is identified as a cable fault fire risk type, the system will generate the corresponding first fire management plan according to this specific risk type and instruct the partition controller to execute the plan. The implementation of this step is based on the fact that cable fault is one of the main causes of cable trench fires. By increasing the monitoring intensity of cables, potential problems can be discovered earlier, thereby effectively reducing the fire risk. In specific implementation, the first fire management plan will first conduct a comprehensive assessment of the cables in the management area to determine the key monitoring objects and key parameters. For example, cables with a long service life or high load may be listed as key monitoring objects. Subsequently, the plan will instruct the partition controller to adjust the configuration and parameter settings of the monitoring equipment. This may include increasing the sampling frequency of the temperature sensor, lowering the trigger threshold of partial discharge detection, or enabling a higher-precision current monitoring mode. In addition, the plan also includes measures such as increasing the inspection frequency or deploying mobile monitoring equipment to provide more comprehensive cable status information. When executing these measures, the partition controller will adjust the monitoring strategy in real time to ensure that the monitoring resources are optimally configured. By implementing this management plan, the system can significantly improve its ability to perceive the cable status and achieve early warning of potential faults. This not only provides maintenance personnel with more adequate response time, but also supports the formulation of more accurate preventive maintenance strategies.

[0104] S1032: If the fire risk type is an external interference fire risk type, a second fire management plan corresponding to the external interference fire risk type is generated, and the partition controller is controlled to execute the second fire management plan, where the second fire management plan is used to increase the monitoring intensity of the environment within the management area.

[0105] Among them, the external interference fire risk type refers to the potential dangerous factors that may cause fires caused by external environmental factors or human operations in the cable trench. In the embodiment of the present application, it can be understood as the fire risk caused by various external reasons other than the cable itself. These risk sources may come from environmental changes, human operational errors, construction interference, natural disasters and other aspects. The external interference fire risk type covers a variety of situations that may cause fires, such as abnormal environmental temperature and humidity, flooding, foreign body intrusion, construction damage, earthquake impact, etc. In actual applications, the system will configure corresponding monitoring equipment and early warning mechanisms according to these external interference fire risk types. For example, in order to deal with the risk of foreign body intrusion, the system may install video surveillance or infrared detection devices; in order to prevent the impact of earthquakes, seismic sensors may be equipped and corresponding emergency plans may be formulated. Through this targeted monitoring and early warning, the system can more quickly discover potential external interference risks, so as to take preventive or response measures in time.

[0106] Among them, the second fire management plan refers to a set of comprehensive prevention, monitoring, response and recovery measures formulated for external interference fire risk types. In the embodiment of the present application, it can be understood as a systematic management strategy specifically for dealing with fire risks caused by external factors. It covers multiple links such as risk identification, environmental monitoring, early warning mechanism, emergency response, personnel management and post-event recovery, aiming to effectively manage and reduce fire risks caused by external interference. In practical applications, the second fire management plan is implemented through a partitioned control cabinet. The control cabinet adjusts the operating parameters of various monitoring equipment according to the instructions in the plan, analyzes the collected environmental data in real time, and initiates corresponding early warning or emergency measures when an abnormality is detected. For example, when an abnormal increase in temperature is detected in the cable trench, the control cabinet may first start the ventilation and cooling equipment. If the situation continues to deteriorate, it may trigger a higher level alarm or initiate an emergency plan.

[0107] When implemented, the second fire management plan will first conduct a comprehensive assessment of environmental factors in the managed area to determine key monitoring parameters and key areas of concern. For example, low-lying areas that are susceptible to flooding may be listed as key monitoring targets. Subsequently, the plan will instruct the partition controller to adjust the configuration and parameter settings of existing environmental monitoring equipment, or add new monitoring equipment. This may include increasing the sampling frequency of temperature and humidity sensors, lowering the alarm threshold of water level sensors, or adding foreign object intrusion detection devices. At the same time, the second fire management plan will also optimize the data analysis algorithm so that the system can more sensitively capture abnormal changes in environmental conditions. For example, multi-parameter joint analysis technology may be used to comprehensively consider multiple factors such as temperature, humidity, and air pressure to more accurately predict potential environmental risks. In addition, the plan may also include measures such as increasing the frequency of environmental inspections or deploying mobile monitoring equipment to provide more comprehensive environmental status information. When implementing these measures, the partition controller will dynamically adjust the monitoring strategy based on real-time environmental data to ensure that monitoring resources are optimally configured. By implementing this management plan, the system can significantly improve its ability to perceive changes in the external environment and achieve early warning of potential external interference risks.
