[0052] The cable safety alarm device, method and equipment based on the wildfire spread model provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0053] Embodiment 1

[0054] Figure 1 Schematic diagram of the structure of the cable safety alarm device based on the wildfire spread model provided in the first embodiment of the present application. Figure 1 As shown, the specific steps include:

[0055] The recognition result acquisition module 101 is used to obtain the recognition result of the satellite positioning system on whether there is a mountain fire in the mountainous area where the monitoring cable is laid;

[0056] The spread data acquisition module 102 is used to acquire the location of the wildfire and the spread data of the wildfire when the wildfire is identified;

[0057] A spreading speed calculation module 103, used to calculate the spreading speed of the wildfire in the direction toward the cable according to the spreading data;

[0058] An estimated time determination module 104 is used to determine the estimated time for the wildfire to spread to the affected area of ​​the monitoring cable according to the spreading speed;

[0059] The alarm module 105 is used to generate an alarm message when the estimated duration is less than the set duration.

[0060] The application scenario of this solution can be the scenario of security monitoring of cables after laying cables in mountainous areas.

[0061] Based on the above scenario, it can be understood that the executor of this scenario can be an intelligent monitoring terminal, such as a desktop computer, a laptop computer, a tablet computer, and an interactive multimedia device, etc., and no excessive limitations are made here.

[0062] The satellite positioning system may be a Beidou navigation positioning system or a GPS (Global Positioning System) positioning system.

[0063] In this solution, an interface for receiving satellite wildfire monitoring can be set in advance for the monitoring system of the monitoring cable, so that when a wildfire is found, the corresponding information can be received in time.

[0064] The satellite positioning system's identification result of whether a wildfire exists may include whether a wildfire exists or not.

[0065] When the presence of a wildfire is identified, the location of the wildfire and the spread data of the wildfire are obtained. Among them, the location of the wildfire can be the location of the fire source when the wildfire occurs. When the location of the fire source is uncertain, the location of the wildfire obtained in real time can also be used as the location of the wildfire. It can be understood that the location of the wildfire can be collected together with the wildfire monitoring information. In addition to the location of the wildfire, the spread data of the wildfire can be obtained. Among them, the spread data of the wildfire can include the formation time of the wildfire, such as the wildfire has been formed for 6 hours, the scale data of the wildfire, such as the wildfire has formed an area of ​​about 1 square kilometer, in addition to this, it can also include the fire intensity data of the wildfire, such as the fire intensity increased sharply in the first hour, and the fire intensity has decayed in the next 5 hours. In addition, it can also include the speed change data of the spread of the wildfire, such as the spread speed is faster in the first 2 hours, and there is basically no faster spread in the next few hours.

[0066] In this solution, after the wildfire spread data is obtained, the spread speed of the wildfire in the direction toward the cable can be calculated based on the spread data.

[0067] The spreading speed can be expressed in m / h, and the spreading speed can be affected by various factors, such as the type of fire source, surrounding vegetation, wind speed and direction, and weather factors. In this solution, since relevant data can be obtained through satellites in the early stages of wildfire formation, the speed information of wildfire can be further determined based on the image data taken by satellites at different times. For example, the spreading speed of wildfire in each direction can be determined based on the expansion range of the wildfire in each direction.

[0068] In this solution, since the monitoring cable needs to be maintained to ensure the safe operation of the cable, the spread speed of the wildfire needs to be calculated in the direction toward the cable. In this solution, the direction toward the cable can be one or more. For example, the wildfire may spread at different speeds at different locations in the direction toward the cable. In this case, the spread speed needs to be calculated for each location to ensure the control of the spread speed of the wildfire and the safe operation of the monitoring cable.

[0069] In this solution, the estimated time for the wildfire to spread to the affected area of ​​the monitoring cable can be determined based on the spreading speed. It can be understood that the affected area can be pre-demarcated or automatically generated based on the location of the cable. For example, in the direction of cable laying, the distance of 200 meters on each side is the affected area. In this solution, the distance can also be changed or manually input based on the importance of the cable, the terrain factors around the cable, etc. For example, the distance can be increased in mountainous terrain, while the distance can be reduced in plain areas such as grasslands, because the grasslands in plain areas have a lower spreading speed after the fire is formed, and the fire does not have a very large impact on the operating safety of the cables installed at high altitudes.

[0070] In this solution, after obtaining the wildfire spread speed, the estimated time for the wildfire to spread to the edge of the affected area can be combined with the influence area of ​​the monitoring cable, and an alarm message is generated when the estimated time is less than the set time. The set time can be 2 hours, or a longer or shorter time. In this solution, after obtaining the spread speed, it is necessary to estimate the time for the wildfire to spread to the edge of the affected area. During the estimation calculation, one or more of the above-mentioned fire source type, surrounding vegetation, wind force and direction, and weather factors can also be considered. Furthermore, the accuracy of the estimated calculation of the estimated time can be improved.

[0071] The technical solution provided in this embodiment includes an identification result acquisition module, which is used to obtain the identification result of the satellite positioning system on whether there is a wildfire in the mountainous area where the monitoring cable is laid; a spread data acquisition module, which is used to obtain the location of the wildfire and the spread data of the wildfire when the presence of the wildfire is identified; a spread speed calculation module, which is used to calculate the spread speed of the wildfire in the direction of the cable according to the spread data; an estimated time determination module, which is used to determine the estimated time for the wildfire to spread to the affected area of ​​the monitoring cable according to the spread speed; and an alarm module, which is used to generate an alarm message when the estimated time is less than the set time. The above technical solution can obtain the time for the wildfire to spread to the area that affects the safe operation of the cable by calculating the spread speed of the wildfire, so as to issue an alarm prompt, and can ensure the safe operation of the monitoring cable after the wildfire occurs, and avoid huge economic losses caused by cable damage.

[0072] In one embodiment, optionally, the device further comprises:

[0073] An environmental information acquisition module, used to obtain wind direction information and wind speed information in the mountainous area where the monitoring cable is laid;

[0074] Accordingly, the spreading speed calculation module is specifically used for:

[0075] The spreading speed of the wildfire in the direction toward the cable is calculated according to the spreading data, the wind direction information and the wind speed information.

[0076] Among them, the environmental information acquisition module can be used to obtain environmental information in mountainous areas. In this solution, the environmental information can include wind direction information and wind speed information in mountainous areas. It should be noted that the wind direction information and wind speed information can be real-time information or statistical information. For example, the wind direction information and wind speed information in weather information can be obtained through micro-meteorological data, or the wind direction information and wind speed information can be obtained through sensors. The above two methods of obtaining wind direction information and wind speed information are real-time information. It is also possible to use statistical data. For example, in July, the mountainous area blows southwest wind from 8 to 12 o'clock every morning, with a wind speed of level 3, and there is no wind from 12 o'clock to 15 o'clock every day. Northeast wind blows from 15 o'clock to 19 o'clock every afternoon, with a wind speed of level 5. The current wind direction and wind speed information can be determined according to the current system time. In this case, it can be determined that the wind direction information and wind speed information are based on statistical information, not real-time information. However, the statistical information also has a certain accuracy and can be used to calculate the spread speed of wildfires.

[0077] After obtaining the wind direction information and wind speed information, the wildfire spread data can be combined to calculate the wildfire spread speed in the direction of the cable. For example, if the wind direction information is consistent with the direction of the wildfire toward the cable, the spread speed will be accelerated. Conversely, if the wind direction information is opposite to the direction of the wildfire toward the cable, the spread speed will be slowed down. At the same time, while speeding up and slowing down the spread speed, different wind forces will affect the spread speed. For example, if the wind direction information is consistent with the direction of the wildfire toward the cable, the greater the wind speed, the greater the acceleration of the spread speed. If the wind direction information is opposite to the direction of the wildfire toward the cable, the greater the wind speed, the greater the slowdown of the spread speed.

[0078] Through such a setting, this scheme can take into account wind direction information and wind speed information while calculating the spread speed, which can improve the accuracy of the spread speed calculation and can accurately estimate the time it takes for the wildfire to spread to the affected area, thereby improving the protection effect of the monitoring cable and preventing the wildfire from affecting the safe operation of the cable.

[0079] In one embodiment, optionally, the device further comprises:

[0080] A vegetation information acquisition module, used to acquire vegetation information in the mountainous area where the monitoring cable is laid;

[0081] Accordingly, the spreading speed calculation module is specifically used for:

[0082] The spreading speed of the wildfire in the direction toward the cable is calculated based on the spreading data and the vegetation information.

[0083] In this solution, the vegetation information of mountainous areas may include the tree content per unit area in the mountainous areas, and the weed coverage per unit area, etc. In addition, it may also include the tree height in the mountainous areas, the weed height in the mountainous areas, etc. In addition, it may also include the growth status of trees in the mountainous areas due to seasonal reasons, and the growth status of weeds, for example, weeds are in a budding state in spring, in a lush growth state in summer and early autumn, and in a withered state in late autumn and winter, etc.

[0084] In this solution, the vegetation information in the mountainous area will directly affect the development trend of the wildfire. For example, if the weeds in the mountainous area are withered and the trees are tall, the wildfire will spread very quickly. However, if the weeds in the mountainous area are lush and the trees in the mountainous area are short, and the vegetation coverage per unit area is small, the wildfire will spread slower. Therefore, in the process of calculating the wildfire spread speed, the vegetation information and the wildfire spread data can be combined to accurately calculate the spread speed of the wildfire toward the cable, improve the calculation accuracy, and ensure the safe operation of the cable.

[0085] Through such a setting, this scheme can take into account the growth status of vegetation in the process of calculating the spreading speed, and can provide more reference information for calculating the spreading speed, thereby improving the accuracy of the spreading speed calculation.

[0086] In one embodiment, optionally, the device further comprises:

[0087] A slope information acquisition module, used to acquire the slope information of the mountainous area where the monitoring cable is laid;

[0088] A path slope statistics module, used to count the slope statistics on the path from the location where the wildfire occurs to the affected area of ​​the monitoring cable;

[0089] Accordingly, the spreading speed calculation module is specifically used for:

[0090] The spreading speed of the wildfire in the direction toward the cable is calculated based on the spreading data and the statistical results of the slope.

[0091] In this solution, the statistical result of the slope on the path from the location of the wildfire to the affected area of ​​the monitoring cable can be the statistical result of the slope on the path from the location of the wildfire to the affected area. For example, the path is 1000 meters, of which the first 300 meters are uphill sections with a slope of 20 degrees, the middle 400 meters are downhill sections with a slope of 15 degrees, and the last 300 meters are uphill sections with a slope of 25 degrees. It can be known that in the process of the spread of wildfires, if it is an uphill section on a path, the spread speed of the wildfire will increase, and if it is a downhill section, the spread speed of the wildfire will slow down. This solution can specifically determine the statistical result of the slope on the path from the location of the wildfire to the affected area by obtaining the height information of each location in the mountainous area. Among them, the statistical results may include how many uphill sections and how many downhill sections the path contains, the length and slope of each section, and so on.

[0092] Through such a setting, this scheme can take into account the slope information on the path from the location of the wildfire to the affected area during the calculation of the spread speed, and can provide more reference information for calculating the spread speed, thereby improving the accuracy of the spread speed calculation.

[0093] Embodiment 2

[0094] Figure 2 This is a schematic diagram of the structure of the cable safety alarm device based on the wildfire spread model provided in the second embodiment of the present application. This solution makes a better improvement on the above embodiment, and the specific improvement is: the spread speed calculation module is specifically used to: adopt the wildfire spread statistical model, perform data matching according to the formation time data and scale data in the wildfire spread data, and use the matched target data as the spread speed.

[0095] like Figure 2 As shown, specifically including the following:

[0096] The recognition result acquisition module 201 is used to obtain the recognition result of the satellite positioning system on whether there is a mountain fire in the mountainous area where the monitoring cable is laid;

[0097] The spread data acquisition module 202 is used to acquire the location of the wildfire and the spread data of the wildfire when the wildfire is identified;

[0098] A spreading speed calculation module 203, used to calculate the spreading speed of the wildfire in the direction toward the cable according to the spreading data;

[0099] An estimated time determination module 204 is used to determine the estimated time for the wildfire to spread to the affected area of ​​the monitoring cable according to the spreading speed;

[0100] An alarm module 205 is used to generate an alarm message when the estimated duration is less than the set duration;

[0101] The spreading speed calculation module 203 is specifically used for:

[0102] A wildfire spread statistical model is used to match the formation time data and scale data in the wildfire spread data, and the matched target data is used as the spread speed.

[0103] The wildfire spread statistical model can be a model obtained by statistically analyzing historical wildfire data. The model can combine the wildfire formation time data, such as M hours after the fire was formed, with the wildfire scale data, such as the current burned area has reached N square meters, to match the data and obtain the matched target data as the wildfire spread rate.

[0104] In this solution, we can use the historical wildfire data as a basis and use the matching results as the spread speed of the wildfire. This can better determine the future spread trend of the wildfire and prepare for subsequent emergency responses. It can effectively avoid the problem of being unable to respond in a timely and effective manner due to the inability to calculate the spread speed of the wildfire.

[0105] The following is a simple example of a code skeleton for a statistical model that simulates the spread of wildfires. Please note that this is just a basic example:

[0106]

[0107]

[0108] Example usage:

[0109] grid_size=100;

[0110] ignition_probability=0.001;

[0111] spread_probability=0.5;

[0112] model=ForestFireModel(grid_size,ignition_probability,spread_probability); model.simulate(100);

[0113] model.visualize();

[0114] Specifically, this basic model can be expanded and improved according to actual physical laws, data requirements, research purposes, etc. For example, considering the impact of factors such as wind direction, terrain, and vegetation type on the spread of wildfires, the following is an example with the wind direction factor added:

[0115]

[0116]

[0117]

[0118] Example usage:

[0119] grid_size=100

[0120] ignition_probability=0.001

[0121] spread_probability=0.5

[0122] wind_direction = 'north'

[0123] model=AdvancedForestFireModel(grid_size,ignition_probability,spread_probability,wind_direction)

[0124] model.simulate(100)

[0125] model.visualize();

[0126] The technical solution provided in this embodiment determines the spread speed of wildfires through a wildfire spread statistical model, and can combine historical wildfire data to make a more accurate estimate of the spread speed of wildfires, thereby improving the accuracy of the calculation results of the wildfire spread speed.

[0127] On the basis of the above technical solution, optionally, the spreading speed calculation module is specifically used to:

[0128] Determining the estimated direction of spread between the location of the wildfire and the area of ​​influence of the monitoring cable;

[0129] A wildfire spread statistical model is adopted to perform data matching based on the formation time data and scale data in the wildfire spread data, as well as any one of the wind direction information and wind speed information, the vegetation information and the slope statistical information, and the matched target data is used as the spread speed in each estimated spread direction.

[0130] Among them, before estimating the spread speed of the wildfire, the estimated spread direction between the location of the wildfire and the affected area can be determined first. Specifically, the range of monitoring cables that the wildfire may spread to can be determined based on the location of the wildfire and the direction of the monitoring cable, and the location of the wildfire is used as the origin to make a ray to the range, so as to obtain the estimated spread direction of the wildfire. It can be understood that the determination of the estimated spread direction can be displayed based on a graphical interface. After obtaining the estimated spread direction, the staff can make adjustments based on experience. For example, after recognizing that the staff has relevant experience or authority, the estimated spread direction can be adjusted according to the adjustment instructions input by the staff, and then the estimated spread direction of the final output is obtained. It should be noted that after the staff makes adjustments, the staff's adjustment results can also be screened for rationality to avoid introducing erroneous estimated spread directions due to staff misoperation, or ignoring the estimated spread direction that is very likely to damage the safety of cable operation.

[0131] After determining the estimated spread direction, a wildfire spread statistical model can be used to perform data matching based on the formation time data and scale data in the wildfire spread data, as well as any one or more of the wind direction information and wind speed information, the vegetation information, and the statistical information of the slope. For example, data matching can be performed based on wind direction information, wind speed information, and vegetation information, or it can be performed based on vegetation information and statistical information of the slope, and so on, and the matched target data can be used as the spread speed in each estimated spread direction.

[0132] The present technical solution provides a solution for determining the estimated spread direction, and further determines the wildfire spread speed based on the wildfire spread statistical model according to the estimated spread direction. In the process of determining the wildfire spread speed, any one or more of the wind direction information and wind speed information, vegetation information and slope statistical information can be used for data matching, so that the matching result is more accurate and the spread speed in each estimated spread direction is more accurate.

[0133] On the basis of the above technical solutions, optionally, the device further includes:

[0134] The impact area determination module is used to determine the impact area of ​​the monitoring cable according to the installation height and installation direction of the monitoring cable, the cable parameters and working parameters of the monitoring cable, and the tower material and tower spacing of the monitoring cable.

[0135] Among them, the determination of the impact area can be related to the installation height of the monitoring cable. For example, the higher the installation height, the smaller the impact range can be. The determination of the impact area can also be related to the installation direction. For example, the size of the impact area can be different for different installation directions. For example, the installation direction is along the ridge, or the installation direction is across the ridge. The demarcation of the impact area of ​​the two is different. In addition, the different cable parameters, working parameters, etc. of the monitoring cable will also result in different impact areas. For example, the cable parameters are high-temperature resistant cables or non-high-temperature resistant cables, cables with insulation layers or bare wire cables. At the same time, different working parameters will also result in different impact areas, such as high-voltage cables or ordinary cables, main line cables or branch cables, etc. In addition, it is necessary to consider that the tower material and tower spacing of the monitoring cable can also be used to determine the impact area of ​​the monitoring cable. Among them, the tower material is a steel tower or a concrete tower. In addition, the different spacing between towers, such as 50 meters or 100 meters, can be used as a basis for determining the impact area of ​​the monitoring cable.
