[0002] The traditional electronic fence management method does not fully consider the topographic differences of different sections of the national boundary, and also ignores the safety requirement differences of each section of the national boundary, resulting in over-deployment of electronic fence in some areas, causing resource waste, or insufficient coverage in critical areas, forming a control loophole, for example, in mountainous border sections, due to complex terrain and serious signal attenuation, the traditional uniform deployment of electronic fence often appears a large number of coverage blind areas, which provides an opportunity for illegal border crossing behavior; while in the plain border section, the over-dense setting points will cause device energy consumption. At the same time, there is a lack of direct intervention means for vehicles crossing the border, and the coverage correlation degree of the electronic fence lacks a quantitative evaluation system, so that the management personnel cannot judge the actual protection performance of each section of the fence, that is, it is impossible to dynamically optimize according to the actual situation.

[0061] In order to make the above objectives, characteristics and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0062] In the following description, a lot of specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other different ways from the description, and those skilled in the art can make similar generalizations without departing from the concept of the present application, so the present application is not limited to the specific embodiments disclosed below.

[0063] Secondly, the "one embodiment" or "embodiment" referred to herein means that the specific features, structures or characteristics can be included in at least one implementation of the present application. "In one embodiment" appearing in different places in the specification does not mean the same embodiment, nor is it an embodiment that is separate from or mutually exclusive with other embodiments.

[0064] Reference Figs. 1-3 As shown in the figure.

[0065] Embodiments further illustrate an electronic fence prevention and management method and system proposed by the present application.

[0066] An electronic fence prevention and management method, the method comprising the following steps:

[0067] Obtaining real-time positioning information of the vehicle, comparing the real-time positioning information with a preset electronic fence area; wherein the electronic fence area is formed by connecting lines of geographic coordinate points to cover the target area;

[0068] If the real-time positioning information of the vehicle is located within the electronic fence area, then control the vehicle to drive normally;

[0069] If the real-time positioning information of the vehicle is located outside the electronic fence area, then trigger a reminder signal;

[0070] After triggering the reminder signal and lasting for a preset time, if the vehicle is still located outside the electronic fence area, then output a restriction instruction to the engine control unit to control the engine speed to linearly decrease to a limit value; wherein the vehicle terminal has an anti-disassembly function, when it is detected that the vehicle terminal is illegally disassembled, then output an inhibition start instruction to the engine control unit to make the vehicle unable to start.

[0071] Continuously obtaining real-time positioning information of the vehicle, comparing it with a preset electronic fence area. The electronic fence area here is formed by connecting lines of geographic coordinate points, for example, in order to control the illegal out-of-border behavior of a certain brand of all-terrain vehicle, a plurality of key geographic coordinate points around the national border are selected, and these points are sequentially connected to enclose an electronic fence covering the target control area of the national border.

[0072] When the real-time positioning of the vehicle is in the electronic fence area, the vehicle is controlled to drive normally, for example, when the vehicle drives in the area where the vehicle is legally sold in the country, the engine and power system are not restricted and can be freely driven. If the real-time positioning of the vehicle appears outside the electronic fence area for the first time, a prompt signal is triggered immediately, for example, when the vehicle temporarily drives out of the electronic fence near the national border due to the driver's operation error, the platform end of the vehicle and the APP end of the driver will receive prompt information synchronously. After the prompt signal is triggered, if the vehicle is still outside the electronic fence area within a preset time (for example, set to 10 minutes), a restriction instruction is output to the engine control unit to control the engine speed to linearly decrease to a limit value, so that the vehicle slows down slowly to avoid driving risks caused by sudden stop.

[0073] The Tbox terminal on the whole vehicle has a disassembly prevention function, and the ECU cannot start normally after the Tbox is disassembled; when the vehicle positioning exceeds the range, the vehicle platform end and the app end immediately perform out-of-range prompting, and after a certain time of prompting, the ECU and the instrument end cooperate with the Tbox terminal to perform speed limiting operation and prompting.

[0074] The vehicle terminal has a disassembly prevention function, and if it is detected that the vehicle terminal is disassembled illegally, an engine control unit output prohibition start instruction is immediately output, so that the vehicle cannot start. For example, in order to illegally transport the vehicle out of the country, the illegal person tries to disassemble the vehicle terminal to evade control, at this time the vehicle will be intercepted because it cannot start, and the possibility of illegal exit is completely blocked.

[0075] Obtain electronic fence data and electronic fence characteristic factors of each section of the national border in the target area;

[0076] Based on the electronic fence data, the coverage correlation degree between the electronic fence set points in each section of the national border is evaluated to obtain a first correlation coefficient;

[0077] The electronic fence characteristic factors and the first correlation coefficient are processed to obtain a second correlation coefficient;

[0078] Based on the first comprehensive correlation coefficient, a second comprehensive correlation coefficient of the electronic fence set coverage data affected by the electronic fence characteristic factors is evaluated;

[0079] The second comprehensive correlation coefficient and the second correlation coefficient are processed to obtain a processing result, and the target area is divided into a control area one and a control area two according to the processing result; the electronic fence of the control area one and the control area two is parameter configured according to the electronic fence set coverage data.

[0080] The correlation fluctuation value is obtained by difference operation between the second comprehensive correlation coefficient and the second correlation coefficient, and the purpose is to quantify the correlation difference between the two. For example, assuming that the second comprehensive correlation coefficient of a certain section of the national border is 0.8, and the second correlation coefficient is 0.6, the correlation fluctuation value is 0.2.

[0081] The reference correlation interval is dynamically adjusted according to the historical coverage stability data and the border security demand. For example, in the plain area of the border, the historical coverage stability data is good, so the border security demand is relatively stable, and the reference correlation interval is set to 0.1-0.3; while in the mountainous area, due to the complex terrain, the historical coverage stability data fluctuates greatly, and the border security demand is higher, so the reference correlation interval is 0.05-0.25.

[0082] According to the relationship between the correlation fluctuation value and the reference correlation interval, the control area is divided. If the correlation fluctuation value is within the reference correlation interval, it is determined that the electronic fence coverage state of the corresponding section is stable coverage, and the section corresponding to the stable coverage is divided into control area one. For example, the correlation fluctuation value of a certain section is 0.2, so the correlation fluctuation value of the section is within the reference correlation interval of the plain area, and the area is control area one. According to the electronic fence setting coverage data of control area one, the signal transmission power and monitoring frequency of the electronic fence are optimized, and the energy consumption is reduced under the premise of ensuring the coverage quality, such as adjusting the signal transmission power from 5W to 4W and the monitoring frequency from once every minute to once every two minutes.

[0083] If the correlation fluctuation value exceeds the reference correlation interval, it is determined that the electronic fence coverage state of the corresponding section is dynamic fluctuation coverage, and the section corresponding to the dynamic fluctuation coverage is divided into control area two. For example, the correlation fluctuation value of a certain mountainous area is 0.3, which exceeds the reference correlation interval of 0.05-0.25 in this area, so the area is control area two. According to the electronic fence setting coverage data of control area two, the electronic fence setting point density is increased, the signal strength is improved, and the monitoring interval is shortened. For example, the setting point density is increased from 5 per kilometer to 8 per kilometer, the signal strength is improved from 40dBm to 50dBm, and the monitoring interval is shortened from once every two minutes to once every minute, and if necessary, a three-dimensional protection network is established by integrating radar and infrared multi-sensor equipment.

[0084] The electronic fence setting coverage data refers to the coverage range, signal strength and overlap rate data of the electronic fence setting point. It can accurately judge the coverage of the electronic fence in different areas, so as to formulate reasonable parameter configuration scheme for control area one and control area two, and realize the management of the electronic fence in the target area.

[0085] Real-time monitoring of the position information of the vehicle in the target area, when the vehicle exceeds the electronic fence area, the engine speed is linearly reduced by the telematics processor, if the telematics processor is detected to be removed, the electronic control unit is controlled to be powered off, and finally the electronic fence prevention and management result is output.

[0086] Real-time monitoring of the position information of the vehicle in the target area is continuously carried out, and the position coordinates of the vehicle are obtained through real-time communication between the positioning base station and the vehicle terminal. For example, the vehicle terminal in the border control area sends position information every 10 seconds.

[0087] When it is monitored that the vehicle exceeds the electronic fence area, the first level response is triggered, and the engine speed is linearly reduced by the telematics processor. Linear reduction means that the engine speed is continuously reduced at a rate until the vehicle speed is reduced to a safe range. Assuming that the initial engine speed of the vehicle is , the linear reduction rate is , the unit is revolutions / second, and after a time of , the engine speed , for example, when a vehicle exceeds the electronic fence, the engine speed is 2000 revolutions / minute, i.e. about 33.3 revolutions / second, and the system sets the reduction rate to 5 revolutions / second. After 5 seconds, the engine speed is reduced to 33.3-5x5=8.3 revolutions / second, and the vehicle will gradually slow down due to insufficient power, thereby avoiding the vehicle from continuing to cross the border.

[0088] If the system detects that the telematics processor is removed, the second level response is triggered, i.e. the electronic control unit is powered off. The electronic control unit is the core control component of the vehicle, and after being powered off, the vehicle will immediately stall, thereby being unable to continue driving.

[0089] The platform end enables the opening / closing of the electronic fence function, when it is selected to be closed, the vehicle can normally drive in and out of the vehicle declaration area without prompting. The Tbox terminal anti-disassembly function can be enabled by the platform end to open / close, the Tbox terminal message sends the "anti-disassembly flag bit 0x01 (anti-disassembly effective)" by default, and when the anti-disassembly function closing signal sent by the platform end is received, the Tbox terminal message sends the "anti-disassembly flag bit 0x00 (anti-disassembly ineffective)". The state can be repeatedly switched, and when the terminal is not connected, the Tbox anti-disassembly function setting is accurate to the last setting.

[0090] The ECU and instrument end receive the corresponding Tbox terminal anti-disassembly function message for 3 times, and set according to the corresponding message and need to be powered off and stored by the ECU and instrument end itself.

[0091] If the vehicle cannot obtain valid positioning information after ACC ON, the timer is paused. If the valid positioning information obtained after ACC ON is out of range and valid positioning information cannot be obtained again, the timer continues, and if valid positioning information within the range is obtained, the timer is cleared.

[0092] Key data of the entire process, including vehicle position trajectory, boundary crossing time, response measure execution, and device state, are recorded after the above monitoring and response operations are completed, and finally the electronic fence prevention and management results are output. These results can provide data support for subsequent optimization of border control strategies, equipment maintenance and upgrading, thereby improving the effectiveness of border control.

[0093] The electronic fence data includes electronic fence set point quantity and distribution data.

[0094] The electronic fence characteristic factors include electronic fence set density characteristics, border length characteristics, regional terrain characteristics, and border demand characteristics.

[0095] The electronic fence data includes electronic fence set point quantity and distribution data. The set point quantity refers to the number of electronic fence devices deployed on a certain section of the border. The distribution data details the spatial location information of each set point, including relative orientation and spacing. Such distribution data provides a spatial basis for subsequent calculation of coverage range and correlation degree.

[0096] The electronic fence characteristic factors include electronic fence set density characteristics, border length characteristics, regional terrain characteristics, and border demand characteristics. The electronic fence set density characteristics refer to the number of electronic fence set points per unit length of the border, and the calculation formula is: set density = set point quantity / border length.

[0097] The border length characteristics are the actual mileage of each section of the border. Different lengths of the border require different resource inputs and coverage strategies when deploying electronic fences. For example, a 20-kilometer-long border and a 50-kilometer-long border have obvious differences in set point quantity planning. A longer border requires more set points or a more optimized distribution method to ensure coverage.

[0098] The regional terrain characteristics cover the terrain types of the border region, such as mountains, plains, water areas, and terrain complexity. Different terrains have a significant impact on the propagation of electronic fence signals and the deployment of devices. The signal of electronic fence in mountainous terrain is easily attenuated by the mountain barrier, and the number of set points needs to be increased or the signal transmission power needs to be improved when deploying the device. The signal propagation in plain terrain is relatively smooth, and the spacing between set points can be appropriately increased.

[0099] The border demand feature is a control strength requirement determined according to the security level of the border. For example, if there are frequent cross-border criminal activities in a border section, the control strength corresponding to the border demand feature is high, and the deployment of the electronic fence requires a higher setting density and a more sensitive monitoring mechanism. In areas with a lower security level, the control strength is relatively low, and the deployment of the electronic fence is relatively loose. For example, the military sensitive area of the border has a high border demand feature, and is equipped with multi-sensor fusion monitoring equipment, while the border demand feature of the border farming and pastoral area is low to middle level, and the monitoring equipment is relatively simple.

[0100] The electronic fence feature factor and the first correlation coefficient are processed to obtain a second correlation coefficient, specifically including the following steps:

[0101] According to the electronic fence feature factor, the coverage correlation degree between the electronic fence setting points in each section of the national border is evaluated to obtain a first comprehensive correlation coefficient; wherein the first comprehensive correlation coefficient includes a density influence correlation coefficient, a length influence correlation coefficient, a terrain influence correlation coefficient and a demand influence correlation coefficient;

[0102] According to the electronic fence setting density feature in the electronic fence feature factor, the coverage correlation degree between the electronic fence setting points in each section of the national border is evaluated to obtain the density influence correlation coefficient;

[0103] According to the national border length feature in the electronic fence feature factor, the coverage correlation degree between the electronic fence setting points in each section of the national border is evaluated to obtain the length influence correlation coefficient;

[0104] According to the regional terrain feature in the electronic fence feature factor, the coverage correlation degree between the electronic fence setting points in each section of the national border is evaluated to obtain the terrain influence correlation coefficient;

[0105] According to the border demand feature in the electronic fence feature factor, the coverage correlation degree between the electronic fence setting points in each section of the national border is evaluated to obtain the demand influence correlation coefficient;

[0106] The density influence correlation coefficient, the length influence correlation coefficient, the terrain influence correlation coefficient and the demand influence correlation coefficient are comprehensively correlated to obtain the first comprehensive correlation coefficient.

[0107] The first comprehensive correlation coefficient and the first correlation coefficient are processed and analyzed to obtain setting optimization information;

[0108] The first comprehensive correlation coefficient and the first correlation coefficient are compared to obtain a similarity value;

[0109] If the similarity value is greater than or equal to a preset similarity threshold, then according to the electronic fence data and the actual correlation influence relationship, the electronic fence setting of each section of the national border in the target area is performed to obtain an electronic fence setting result;

[0110] If the similarity value is less than the preset similarity threshold, optimization information is set for the electronic fence output of each section of the national boundary line in the target region.

[0111] The national boundary line is divided according to the set optimization information to obtain a control edge section and a coverage center section, and electronic fence setting coverage data of the control edge section and the coverage center section are obtained respectively.

[0112] The coverage correlation degree of the electronic fence setting coverage data is evaluated to obtain a second correlation coefficient.

[0113] The coverage correlation degree between the electronic fence setting points in each section of the national boundary line is evaluated based on the electronic fence characteristic factors to obtain a first comprehensive correlation coefficient. The higher the density in the electronic fence setting density feature, the more dense the setting points, and the more sufficient the coverage overlap between adjacent setting points. The density influence correlation coefficient is evaluated accordingly. By judging the coverage range overlap of the setting points under the density, the density influence correlation coefficient is obtained as 0.8. If the setting points are not reasonably distributed in a long national boundary line, a coverage breakpoint occurs. The coverage correlation degree between the electronic fence setting points in each section of the national boundary line is evaluated in combination with the length feature of the national boundary line to obtain a length influence correlation coefficient. For example, for a 3000 km long national boundary line, the length influence correlation coefficient is 0.7 due to the uniform distribution of the setting points. In terms of regional terrain features, mountainous terrain can cause serious attenuation of the electronic fence signal and reduce the coverage correlation degree, while plain terrain is conducive to signal propagation and has a high coverage correlation degree. The terrain influence correlation coefficient is obtained accordingly, such as a terrain influence correlation coefficient of 0.5 for a mountainous section and a terrain influence correlation coefficient of 0.9 for a plain section. In terms of border demand features, high security demand areas require a high coverage correlation degree, and low demand areas can appropriately reduce the coverage correlation degree, thereby obtaining a demand influence correlation coefficient. For example, the demand influence correlation coefficient of a high demand area is 0.9, and the demand influence correlation coefficient of a low demand area is 0.6. The density influence correlation coefficient, the length influence correlation coefficient, the terrain influence correlation coefficient, and the demand influence correlation coefficient are comprehensively correlated and evaluated, which can be achieved by weighted summation. Assuming that the weights of the factors are w1, w2, w3, and w4, and w1+w2+w3+w4=1, the first comprehensive correlation coefficient is w1×density influence correlation coefficient+w2×length influence correlation coefficient+w3×terrain influence correlation coefficient+w4×demand influence correlation coefficient. For example, for a certain section of the national boundary line, w1=0.3, w2=0.2, w3=0.3, and w4=0.2, and the correlation coefficients of the factors are 0.8, 0.7, 0.5, and 0.9 respectively. The first comprehensive correlation coefficient is 0.3×0.8+0.2×0.7+0.3×0.5+0.2×0.9=0.24+0.14+0.15+0.18=0.71.

[0114] The first comprehensive correlation coefficient and the first correlation coefficient are processed and analyzed to obtain the set optimization information. First, the two are compared to obtain a similarity value. The similarity value can be calculated as the ratio of the absolute value of the difference to the average value of the two, i.e., similarity value = |first comprehensive correlation coefficient - first correlation coefficient| / ((first comprehensive correlation coefficient + first correlation coefficient) / 2). If the similarity value is greater than or equal to a preset similarity determination threshold, such as a preset similarity determination threshold of 0.2, if the calculated similarity value is 0.15, since the similarity value is less than the preset similarity determination threshold, the electronic fence setting result of each section of the national boundary in the target area is obtained according to the electronic fence data and the actual correlation influence relationship; if the similarity value is 0.25, since the similarity value is greater than the preset similarity determination threshold, the set optimization information of the electronic fence of each section of the national boundary in the target area is output, such as the need to increase the number of set points and adjust the distribution of set points for a section of the national boundary.

[0115] According to the set optimization information, the national boundary is divided into a control edge section and a coverage center section. The control edge section is a relatively weak coverage area of the electronic fence, which is prone to coverage gaps. The coverage center section is a stable coverage area of the electronic fence, which is closely related. For example, according to the set optimization information, the part close to the mountainous area is the control edge section, and the plain hinterland is the coverage center section. Electronic fence setting coverage data of the control edge section and the coverage center section are obtained respectively. These data include coverage range, signal strength, and overlap rate.

[0116] The coverage correlation degree of the electronic fence setting coverage data is evaluated to obtain a second correlation coefficient. First, the spatial distribution characteristics of the electronic fence setting points in the control edge section and the coverage center section are extracted, including relative orientation and distance; the coverage radiation range of adjacent electronic fence setting points is determined through the signal emission parameters of the electronic fence setting points; the overlap area of the coverage radiation range of adjacent electronic fence setting points is calculated, and the initial coverage correlation degree is determined according to the morphological characteristics of the overlap area; the signal attenuation law of different sections under different environmental conditions is judged, and the initial coverage correlation degree is corrected according to the attenuation law; the second correlation coefficient is obtained by weighting the corrected initial coverage correlation degree combined with the spatial distribution characteristics. For example, the distance between the set points in the coverage center section is small, and the signal is strong. After weighting the corrected initial coverage correlation degree, the second correlation coefficient is 0.85, and the second correlation coefficient of the control edge section is 0.55.

[0117] Based on the electronic fence data, the coverage correlation degree between the electronic fence setting points in each section of the national boundary is evaluated to obtain a first correlation coefficient, which includes the following steps:

[0118] The spatial distribution characteristics of the electronic fence setting points in each section of the national boundary are extracted, including the relative orientation and distance of the electronic fence setting points in the national boundary;

[0119] determine the coverage radiation range of adjacent electronic fence setting points through the signal transmission parameters of the electronic fence setting points;

[0120] calculate the overlapping area of the coverage radiation range of adjacent electronic fence setting points, and determine the initial coverage correlation degree according to the morphological characteristics of the overlapping area;

[0121] determine the signal attenuation law of the electronic fence setting points in different environmental conditions in each section of the national border, and correct the initial coverage correlation degree according to the attenuation law;

[0122] combine the spatial distribution characteristics of the electronic fence setting points in each section of the national border to perform weighted processing on the corrected initial coverage correlation degree to obtain a first correlation coefficient.

[0123] First, the spatial distribution characteristics of the electronic fence setting points in each section of the national border are extracted, wherein the relative position refers to the positional relationship of the setting points in the direction of the national border, such as a national border with an east-west direction, and the setting points are located on the north and south sides of the line respectively; the interval is the distance between adjacent setting points. These spatial distribution characteristics are the basis for subsequent analysis of coverage correlation.

[0124] Then, the coverage radiation range of adjacent electronic fence setting points is determined through the signal transmission parameters of the electronic fence setting points. The signal transmission parameters include transmission power and frequency, and different parameters correspond to different coverage radii. Assuming that the transmission power of a setting point is P, according to the technical specifications of the device, the radius R of the coverage radiation range is calculated by the formula , k is a constant related to the type of device. For example, when k = 20 and P = 25 W, R = 100 meters, that is, the coverage radiation range of the setting point is a circular area with a radius of 100 meters and the setting point as the center.

[0125] Then, the overlapping area of the coverage radiation range of adjacent electronic fence setting points is calculated, and the initial coverage correlation degree is determined according to the morphological characteristics of the overlapping area. The morphology of the overlapping area includes the overlapping area and the degree of fit of the overlapping shape. Assuming that the coverage radii of two adjacent setting points are R1 and R2, and the interval is d, there is an overlapping area when d < R1 + R2. The overlapping area is calculated by a geometric formula, and the initial coverage correlation degree is determined by the ratio of the overlapping area to the sum of the areas of the two coverage areas, that is, the initial coverage correlation degree = S 重叠 / (S1+S2), S1=πR1 2 , S2=πR2 2 . For example, R1 = 100 meters, R2 = 100 meters, and d = 150 meters. Through calculation, S 重叠 ≈3.14×(100 2 -(75 2))≈13737.5 square meters, S1+S2=2x3.14x100 2 =62800 square meters, initial coverage correlation degree ≈ 13737.5 ÷ 62800 ≈ 0.22.

[0126] The signal attenuation law of the electronic fence setting point in each section of the national boundary line under different environmental conditions is judged, and the initial coverage correlation degree is corrected according to the attenuation law. Different environmental conditions such as terrain (mountainous area, plain) and climate (rainy day, sunny day) will result in different signal attenuation degrees. Taking the mountainous terrain as an example, the signal attenuation coefficient is 0.8 for each 100-meter-high mountain, that is, the signal strength becomes 80% of the original. If a certain overlapping area is in a mountainous environment, the actual effective coverage correlation degree after attenuation needs to be multiplied by the attenuation coefficient on the basis of the initial coverage correlation degree. Assuming that the attenuation coefficient is 0.7, the corrected coverage correlation degree = 0.22x0.7 = 0.154.

[0127] Finally, the first correlation coefficient is obtained by weighting the corrected initial coverage correlation degree combined with the spatial distribution characteristics of the electronic fence setting point in each section of the national boundary line. The spacing and relative orientation in the spatial distribution characteristics have different importance to the coverage correlation, so different weights are given. Assuming that the weight of the spacing is w5 and the weight of the relative orientation is w6, and w5+w6=1, then the first correlation coefficient = w5x (corrected initial coverage correlation degree 1) + w6x (corrected initial coverage correlation degree 2). For example, the weight of the spacing w5 is 0.6 and the weight of the relative orientation w6 is 0.4 in a certain section of the national boundary line, and the coverage correlation degree due to the spacing factor after correction is 0.154 and the coverage correlation degree due to the relative orientation factor is 0.2, then the first correlation coefficient = 0.6x0.154+0.4x0.2 = 0.0924+0.08 = 0.1724. Through such weighting processing, the influence of the spatial distribution characteristics on the coverage correlation can be comprehensively reflected, so as to obtain the first correlation coefficient.

[0128] Based on the first comprehensive correlation coefficient, a second comprehensive correlation coefficient of the electronic fence setting coverage data affected by the electronic fence characteristic factor is evaluated, which specifically includes the following steps:

[0129] The influence weight of the electronic fence characteristic factor on the electronic fence setting coverage data is judged to divide the electronic fence characteristic factor into different levels according to the influence weight;

[0130] The electronic fence characteristic factor and the electronic fence setting coverage data of each level are associated and mapped according to the first comprehensive correlation coefficient to obtain a characteristic influence coefficient;

[0131] The interaction between different levels of electronic fence characteristic factors is judged, and the characteristic influence coefficient is coupled and corrected according to the interaction strength;

[0132] The coupling corrected feature influence coefficient is dynamically correlated with the first comprehensive correlation coefficient to obtain a second comprehensive correlation coefficient.

[0133] First, the influence weight of the electronic fence feature factor on the historical influence of the electronic fence setting coverage data is determined, and the electronic fence feature factors are hierarchically divided according to the influence weight. In terms of the length of the national border feature, if the point distribution of the longer national border is unreasonable, it is easy to cause obvious fluctuation of the coverage data. According to the significant degree of the historical influence, the weight is determined. In the regional terrain feature, the attenuation influence of the mountain terrain on the coverage data is much greater than that of the plain, so the influence weight of the mountain terrain is higher than that of the plain. In the border demand feature, the high security demand area has high requirements for the integrity of the coverage data, and the influence weight is also higher. Assuming that the influence weight of the setting density feature is w1=0.3, the length of the national border feature is w2=0.2, the regional terrain feature is w3=0.3, and the border demand feature is w4=0.2, the feature factors are divided into different levels according to these weights, such as the core layer (such as setting density, regional terrain), the important layer (such as the length of the national border), the general layer (such as the border demand), etc.

[0134] Then, the electronic fence feature factors of each level are associated with the electronic fence setting coverage data to obtain the feature influence coefficient according to the first comprehensive correlation coefficient. For example, the setting density feature of the core layer, when the first comprehensive correlation coefficient is 0.7, the feature influence coefficient corresponding to the setting density feature is 0.7×w1=0.7×0.3=0.21; the length of the national border feature of the important layer, if the first comprehensive correlation coefficient is 0.7, the feature influence coefficient is 0.7×w2=0.7×0.2=0.14; and the feature influence coefficients of the feature factors of each level are obtained in the same way.

[0135] Then, the interaction between the electronic fence feature factors of different levels is determined, and the feature influence coefficient is coupled and corrected according to the interaction strength. For example, the setting density feature (core layer) and the regional terrain feature (core layer) have interaction, in the case of mountain terrain and high setting density, the synergistic effect of the two makes the change degree of the coverage data greater than the sum of the individual action, assuming that the interaction strength coefficient is 1.2, then the coupling corrected feature influence coefficient of the two feature factors is (0.21+0.21)×1.2=0.504; the interaction between the length of the national border feature (important layer) and the border demand feature (general layer) is weak, the interaction strength coefficient is 0.8, and the coupling corrected feature influence coefficient is (0.14+0.14)×0.8=0.224.

[0136] Finally, the coupling-corrected feature influence coefficient is dynamically correlated with the first comprehensive correlation coefficient to obtain a second comprehensive correlation coefficient. Assuming that the coupling-corrected total feature influence coefficient is C (for example, C = 0.504 + 0.224 = 0.728 in the above example), the second comprehensive correlation coefficient = the first comprehensive correlation coefficient * C + the first comprehensive correlation coefficient * (1-C) * k, k is a dynamic correlation coefficient, which is adjusted according to the actual scene, and here it is assumed that k = 0.5, that is, the second comprehensive correlation coefficient is 0.7 * 0.728 + 0.7 * (1-0.728) * 0.5 = 0.5096 + 0.7 * 0.272 * 0.5 = 0.5096 + 0.0952 = 0.6048. Through such operation, the comprehensive influence of the electronic fence feature factor on the set coverage data can be quantified, so as to obtain the second comprehensive correlation coefficient.
