[0015] It should also be understood that the term " / and" as used in the specification and appended claims of the present application refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0016] In the related art, electronic fence intrusion detection may only be able to detect that an object has touched, but it is difficult to determine the specific situation of the touching object (such as whether someone maliciously intrudes, an animal accidentally touches, or other objects accidentally touch, etc.) and type, and it is difficult to accurately determine whether someone has intruded, which may result in false alarms and missed alarms, leading to low security and reliability of the protected area of the electronic fence. To solve the above problems, the embodiments of the present application provide an electronic fence intrusion detection method and an electronic fence device.

[0017] In this method, by continuously receiving a touch signal, touch feature detection is performed based on the touch signal to obtain touch information; then, intrusion information is determined according to the situation of the touch object that touches the electronic fence indicated by the touch information, which can effectively determine the specific situation of the touch object, including whether it is a malicious intrusion, an accidental touch by an animal, or an accidental touch by other objects, etc., so as to accurately determine whether someone or other objects have intruded. This method can not only detect that an object has touched, but also determine the specific situation and type of the touch object, and accurately determine whether someone has intruded, improving the security and reliability of the protected area of the electronic fence.

[0018] The electronic fence intrusion detection method provided by the embodiments of the present application can be applied to an electronic fence intrusion detection device. At this time, the electronic fence intrusion detection device is the execution subject of the electronic fence intrusion detection method provided by the embodiments of the present application, and the embodiments of the present application do not impose any restrictions on the specific type of the electronic fence intrusion detection device.

[0019] For example, the electronic fence intrusion detection device further includes a control device; the control device can be a tablet computer, a notebook computer, a desktop computer, a smart large screen, a computer, etc., but is not limited thereto.

[0020] To better understand the electronic fence intrusion detection method provided by the embodiments of the present application, the following is an exemplary introduction to the specific implementation process of the electronic fence intrusion detection method provided by the embodiments of the present application.

[0021] Figure 1 The schematic flowchart of the electronic fence intrusion detection method provided by the embodiments of the present application is shown. The electronic fence intrusion detection method includes: S100, continuously receiving a touch signal; where the touch signal is a signal obtained after the electronic fence is touched by a touch object.

[0022] It can be understood that continuously receiving touch signals means continuously receiving touch signals generated by the electronic fence. These touch signals may originate from a variety of touch objects, including but not limited to people, animals, or other inanimate objects. It can be continuously detected by a sensor. The control device is communicatively connected to the sensor, and the sensor transmits the detected signal to the control device; the sensor is connected to the electronic fence and can capture and transmit these touch signals to the receiving unit in real time; for example, the sensor can be a pressure sensor, an infrared sensor, or a microwave sensor, etc. The sensor can detect the physical changes or signals generated when the electronic fence is touched and convert them into electrical signals for transmission.

[0023] In a possible implementation, after S100, continuously receiving touch signals, it includes: S101, when a touch signal is received, obtain the position of the touch object; where the position of the touch object is the azimuth value of the touch object.

[0024] Exemplarily, when a touch signal is received, the specific position of the touch object can be determined by multiple installed sensor arrays; the sensor array can capture the precise position information when the touch object contacts the electronic fence, thereby generating a touch position map, and obtaining the position of the touch object according to the touch position map; where the sensor array can be an array, and can include an infrared sensor array, a microwave sensor array, or a pressure sensor array, etc. The sensor array can accurately locate the position of the touch object through infrared radiation, microwave reflection, or pressure change respectively; the infrared sensor array can determine the position of the touch point by detecting the difference in infrared radiation; the microwave sensor array locates the touch object through the reflection time and intensity of the microwave signal; while the pressure sensor array directly identifies the touch position through the pressure distribution.

[0025] S102, extract the position information of the boundary of the electronic fence; where the position information is used to indicate multiple azimuth values of the boundary.

[0026] It can be understood that the multiple azimuth values of the boundary indicated by the position information can be understood that the shape of the boundary is circular or square or irregular. A single azimuth value can be understood as a point, then multiple azimuth values are multiple points that make up a circle or a square or an irregular shape, that is, multiple azimuth values form the boundary.

[0027] Exemplarily, the position information of the boundary of the electronic fence can be obtained by pre-surveying the electronic fence, and the survey results can be stored in the storage unit. The boundary position information includes but is not limited to the perimeter of the electronic fence, the coordinates of each key point, etc. These information serve as the basis for subsequent judgment of whether the touch object invades.

[0028] S103. Perform position analysis based on the position information of the touched object and the position of the boundary to determine whether the position of the touched object is within the position of the electronic fence.

[0029] Exemplarily, by the azimuth value of the touched object indicated by the position of the touched object and the multiple azimuth values of the boundary indicated by the position information of the boundary, determine all the azimuth values within the boundary formed by the multiple azimuth values. If the azimuth value of the touched object indicated by the position of the touched object is the same as one of all the azimuth values within the boundary formed by the multiple azimuth values, it proves that the position of the touched object is within the position of the electronic fence.

[0030] With such a setting, it can be accurately determined whether the touched object is located within the protected area of the electronic fence. If the touched object is indeed within the electronic fence, further analysis can be continued based on the touch information, laying a foundation for subsequent intrusion detection.

[0031] In a possible implementation, please refer to Figure 2 , S103. Perform position analysis based on the position information of the touched object and the position of the boundary to determine whether the position of the touched object is within the position of the electronic fence, including: S1031. Obtain the fence area of the electronic fence according to the multiple azimuth values indicated by the position information of the boundary; It can be understood that the fence area is enclosed by multiple azimuth values. The area within the fence area is the area to prevent intrusion, such as a campus area, a factory area, etc., but not limited to this.

[0032] S1032. Extract the fence area of the electronic fence to obtain all the azimuth values of the fence area.

[0033] Exemplarily, extract all the azimuth values within the fence area to obtain all the azimuth values of the fence area. For example, a circle, a square, or an ellipse, the interior of the circle, square, or ellipse is the area, and all the points inside the circle, square, or ellipse are the azimuth values within the area.

[0034] S1033. Compare the azimuth value of the touched object with all the azimuth values of the fence area for coincidence.

[0035] Exemplarily, compare the azimuth value of the touched object with all the azimuth values of the fence area for equality.

[0036] S1034. In the case where the coincidence comparison is completed, if 0 azimuth values of the fence area are the same as the azimuth value of the touched object, it will be determined that the position of the touched object is not within the position of the electronic fence.

[0037] It can be understood that if there are 0 azimuth values of the fence area among all the azimuth values of the fence area that are the same as the azimuth value of the touched object, it can be understood that the touched object is not within the fence area; for example, in the case where the coincidence comparison is completed, for example, there are A, B, C, D, E, F, G, H, and I within a circle. If the azimuth value of the touched object is X, it proves that the touched object is not inside the circle; another example is that all the coordinate values within a square area are from (1, 1) to (1, 10), from (2, 1) to (2, 10),..., from (10, 1) to (10, 10); if the coordinate value of the touched object is (11, 8), since (11, 8) is the same as one of the coordinate values within the square area, it proves that the touched object is not within the square area.

[0038] In a possible implementation manner, please refer to Figure 2 , the method further includes: In the case where the coincidence comparison is completed, if at most 1 azimuth value of the fence area among all the azimuth values of the fence area is the same as the azimuth value of the touched object, it will be determined that the position of the touched object is within the position of the electronic fence.

[0039] Exemplarily, if there is 1 azimuth value of the fence area among all the azimuth values of the fence area that is the same as the azimuth value of the touched object, it can be understood that the touched object is within the fence area; for example, in the case where the coincidence comparison is completed, there are A, B, C, D, E, F, G, H, and I within a circle. If the azimuth value of the touched object is C, it proves that the touched object is inside the circle; another example is that all the coordinate values within a square area are from (1, 1) to (1, 10), from (2, 1) to (2, 10),..., from (10, 1) to (10, 10); if the coordinate value of the touched object is (5, 8), since (5, 8) is the same as one of the coordinate values within the square area, it proves that the touched object is within the square area.

[0040] With such a setting, it can accurately determine whether the touched object is located within the protection area of the electronic fence, providing a key basis for subsequent intrusion detection.

[0041] S200, perform touch feature detection based on the touch signal to obtain touch information; where the touch information is used to reflect the situation of the touched object that touches the electronic fence.

[0042] It can be understood that the touch feature can include but is not limited to touch duration, touch times, the shape of the touched object, etc., but is not limited thereto.

[0043] Exemplarily, after continuously receiving the touch signal, perform touch feature detection, and determine the situation of the touched object that touches the electronic fence according to the touch feature.

[0044] In a possible implementation manner, please refer toFigure 3 , S200, performs touch feature detection based on the touch signal to obtain touch information, including: S210, when the position of the touched object is not within the position of the electronic fence based on the touch signal, performs first feature analysis on the touched object to obtain first information; wherein, the first information is used to indicate the touch duration and touch count of the touched object on the electronic fence.

[0045] Exemplarily, based on the touch signal and when the position of the touched object is not within the position of the electronic fence, performs detection of the touch duration and touch count on the touched object to obtain first information.

[0046] S220, performs false touch judgment on the touch duration and touch count indicated by the first information to obtain judgment information; wherein, the judgment information is used to reflect whether the touched object is a false touch situation or a non-false touch situation, the false touch situation includes passive false touch and active false touch, and the non-false touch situation includes human climbing and / or human intrusion.

[0047] It can be understood that passive false touch can be understood as the branch being blown by the wind, resulting in the branch touching the electronic fence, which is a situation affected by the external environment, so it is passive false touch; active false touch can be understood as actively touching the electronic fence due to foraging or other reasons, so it is active false touch. Active false touch can include animals, such as common pets like cats and dogs or wild animals, etc.; human climbing and / or human intrusion refers to the behavior of someone deliberately climbing the electronic fence or illegally entering the protected area. During the false touch judgment process, it can be judged according to a preset threshold or rule. For example, if the touch duration is extremely short and the touch count is less than the threshold, it proves that it is very likely to be a false touch; on the contrary, if the touch duration is long and the touch count is frequent, both being greater than the preset threshold, it is very likely to be human climbing or intrusion. Further, in order to more accurately judge the situation of the touched object, other information can also be combined for analysis, such as environmental information, time information, etc. For example, in the night or a dim environment, the possibility of animal false touch is higher; while in the day or a well-lit environment, the possibility of human climbing or intrusion is higher.

[0048] In a possible implementation, please refer to Figure 4 , S220, performs false touch judgment on the touch duration and touch count indicated by the first information to obtain judgment information, including: S221, obtains time interval information; wherein, the time interval information is used to indicate the interval time between consecutive touches.

[0049] Exemplarily, the time interval information can be obtained by calculating the time difference between two adjacent touch signals. In the case of continuously receiving touch signals, record the timestamps of each touch signal, and by calculating the difference between two adjacent timestamps, the interval time between consecutive touches can be obtained.

[0050] S222, input the interval time between consecutive touches indicated by the time interval information, the touch duration of the touched object, and the number of touches into the false touch judgment model, and the false touch judgment model makes a judgment according to the judgment logic to obtain judgment information; wherein, the judgment logic includes the judgment logic for passive false touch, the judgment logic for active false touch, and the judgment logic for non-false touch situations. The judgment logic for passive false touch is short-time single touch, that is, T is X, C is Y. The judgment logic for active false touch is high-frequency low-time touch, that is, T is X, C is Y, J is Z. The judgment logic for non-false touch situations is continuous touch and periodic interval, that is, T is X, C is Y, J is Z, where T is the touch duration, C is the number of touches, and J is the interval time indicated by the time interval information.

[0051] It can be understood that the false touch judgment model takes the interval time between consecutive touches indicated by the time interval information, the touch duration of the touched object, and the number of touches as inputs, makes judgments according to the judgment logic for passive false touch, the judgment logic for active false touch, and the judgment logic for non-false touch situations, and takes the judgment information as the output. The false touch judgment model is obtained by training a large amount of data through the model.

[0052] Exemplarily, in the false touch judgment model, different judgment logics correspond to different combinations of touch characteristics. For example, for passive false touch, taking a branch as an example, the touch caused by the branch being blown by the wind is usually short and single, so the judgment logic is set as short-time single touch, that is, the touch duration T is, for example, 0.3 seconds, and the number of touches C is, for example, 2 times per minute. For false touches by animals such as cats and dogs, since they may move near the electronic fence due to foraging or other reasons, resulting in high-frequency low-time touches, the judgment logic is set as high-frequency low-time touch, that is, the touch duration T is, for example, 0.8 seconds, the number of touches C is, for example, 6 times per minute, and there may be a short time interval J, for example, multiple touches within 2 seconds. For non-false touch situations, such as human climbing or intrusion, since this behavior is usually continuous and may be accompanied by periodic intervals (such as rest or adjusting posture during climbing), the judgment logic is set as continuous touch and periodic interval, that is, the touch duration T is, for example, 5 seconds, the number of touches C is, for example, 3 times), and there is a long time interval J, for example, 5 seconds, to distinguish consecutive touch behaviors, where T can be seconds, minutes, hours, etc. but is not limited to this; C can be the number of times per minute, per second, or per hour, etc. but is not limited to this; J can be in seconds, minutes, hours, etc. but is not limited to this; In addition, the judgment logic for passive accidental touch is not limited to the above-exemplified content (the exemplified content is a branch), and can also be other passive situations, such as touches caused by natural phenomena like rain, hail, or others. Touches caused by these natural phenomena also have the characteristics of short-term single-touch. Similarly, the judgment logic for active accidental touch is not limited to the above-exemplified content (the exemplified content is animals, cats, and dogs), and can also be touches caused by birds, insects, etc., which also have the characteristics of high-frequency and low-duration touch.

[0053] S223, if the currently used judgment logic output by the accidental touch judgment model is short-term single-touch and / or high-frequency and low-duration touch, then determine that the currently touched object is the accidental touch situation reflected by the judgment information.

[0054] Exemplarily, if the currently used judgment logic output by the accidental touch judgment model is short-term single-touch and / or high-frequency and low-duration touch, then determine that the currently touched object is an animal or a plant, that is, determine that the currently touched object is the accidental touch situation reflected by the judgment information.

[0055] S224, if the currently used judgment logic output by the accidental touch judgment model is continuous touch and periodic interval, then determine that the currently touched object is a non-accidental touch situation reflected by the judgment information.

[0056] Exemplarily, if the currently used judgment logic output by the accidental touch judgment model is outputting continuous touch and periodic interval, then determine that the currently touched object is a person, that is, determine that the currently touched object is the accidental touch situation reflected by the judgment information.

[0057] With such a setting, the judgment accuracy of the situation of the touched object can be improved, the situations of false alarms and missed alarms can be reduced, and thus the safety protection effect of the electronic fence can be more effectively guaranteed.

[0058] In a possible implementation manner, if the judgment information reflects that the currently touched object is a non-accidental touch situation, the electronic fence intrusion detection system can further perform an alarm operation. The alarm operation can include but is not limited to emitting an alarm sound, sending an alarm signal to the monitoring center, starting a camera to record video, etc., so as to respond to and process the intrusion event in a timely manner.

[0059] S230, if the touched object reflected by the judgment information is a non-accidental touch situation, perform a second feature analysis on the touched object to obtain second information; where the second information is used to reflect the morphological situation of the touched object.

[0060] Exemplarily, the second feature analysis may include analyzing features such as the shape and size of the touched object. For example, based on the data obtained by the sensor array, the contour shape of the touched object can be analyzed. Further, in combination with other sensor data (such as pressure distribution data), the size of the touched object can be estimated. In addition, the form of the touched object can be inferred by analyzing signals such as the pressure or vibration generated by the touched object on the electronic fence.

[0061] In a possible implementation, refer to Figure 5 , S230. If it is determined that the touched object reflected by the judgment information is not a false touch, perform a second feature analysis on the touched object to obtain second information, including: S231. If it is determined that the touched object reflected by the judgment information is not a false touch, perform a vibration signal pattern analysis on the touched object near the electronic fence to obtain first analysis information; wherein, the first analysis information is used to reflect the distribution of the vibration signal.

[0062] Exemplarily, when a touched object approaches the electronic fence, vibrations will be generated. By detecting the vibrations and analyzing features such as the frequency, amplitude, and distribution of these vibration signals, the distribution of the vibration signals of the touched object can be obtained. For example, different objects will generate different vibration signal patterns due to their different masses and shapes. Therefore, by comparing and analyzing the vibration signal patterns, the type or features of the touched object can be preliminarily judged; specifically, perform pattern matching on the vibration signal distribution indicated by the first analysis information to obtain whether the touched object is a preset specific object, and determine the specific type of the touched object according to the obtained specific object; wherein, the specific type includes but is not limited to animals, humans, etc. For example, if the matching result shows that the vibration signal pattern of the touched object matches the preset "cat and dog" pattern, it can be determined that the touched object is an animal such as a cat or a dog. If the matching result matches the "human" pattern, it can be determined that the touched object is a human.

[0063] In a possible implementation, refer to Figure 5 , S231. If it is determined that the touched object reflected by the judgment information is not a false touch, perform a vibration signal pattern analysis on the touched object near the electronic fence to obtain first analysis information, including: S2311. Detect multiple contact areas of the touched object on the fence in real time; wherein, the contact area is the area of the fence touched by the touched object.

[0064] Exemplarily, multiple vibration sensors can be set up to detect multiple contact areas of the touched object with the fence in real time. The vibration sensors can capture the vibration signals generated when the touched object contacts the electronic fence and transmit these signals to the processing unit for analysis; by analyzing these vibration signals, the specific positions and areas where the touched object contacts the electronic fence can be determined. The multiple vibration sensors can be set up successively and at intervals on the fence; among them, the fence can be a campus fence, a corporate or company fence, or other fence structures, etc.

[0065] S2312. Obtain the respective low-frequency values generated when the touched object contacts each contact area according to the multiple contact areas detected in real time.

[0066] It can be understood that this can be achieved by performing signal processing on the vibration sensors set for each contact area. Specifically, after the vibration sensors capture the vibration signals, they will convert them into electrical signals, which contain information such as the frequency and amplitude of the vibration signals. Then, these electrical signals are filtered to remove high-frequency noise and interference and retain the low-frequency components. The low-frequency components reflect the vibration characteristics when the touched object contacts the electronic fence, that is, the required low-frequency values. After obtaining these low-frequency values, further pattern matching and analysis can be performed to determine the type or characteristics of the touched object.

[0067] S2313. Analyze the periodic rise or fall presented by the touched object based on the respective low-frequency values to obtain the touch waveform of the touched object.

[0068] Exemplarily, this can be achieved by performing time series analysis on the low-frequency values. Specifically, the low-frequency values detected in each contact area are arranged in chronological order to form time series data. Then, the periodic changes of the vibration signals generated when the touched object contacts the electronic fence are identified from these time series data; the periodic changes reflect the touch waveform of the touched object. Different characteristics of the touch waveform can be used to further distinguish the type of the touched object. For example, the waveform generated when a human climbs may be significantly different from the waveform generated when an animal runs. By comparing and analyzing these waveform characteristics, the specific situation of the touched object can be judged more accurately.

[0069] In addition, the type or behavioral characteristics of the touched object can be further determined based on the touch waveform. For example, by comparing and analyzing the touch waveform with the waveform templates in a preset waveform library, it can be determined whether the touched object is a specific type, such as a human, an animal, etc., or its behavioral characteristics, such as climbing, running, etc. The establishment of the waveform library can be achieved by collecting and analyzing data of a large number of actual touch events, extracting the typical waveforms of different touched objects and behavioral characteristics, and forming them after preprocessing and feature extraction. In the process of waveform matching, methods such as similarity calculation and machine learning can be used to judge the matching degree between the touch waveform and the waveform template, so as to determine the type or behavioral characteristics of the touched object. In addition, in order to further improve the accuracy of the judgment, other sensor data can also be combined for analysis. For example, an infrared sensor, a radar sensor, etc. can be used to detect the movement trajectory and speed of the touched object, or a sound sensor can be used to detect the sound characteristics generated by the touched object, etc. The fusion of multi-source information can be realized through a data fusion algorithm, and the data obtained by different sensors are fused and processed to improve the judgment accuracy of the situation of the touched object.

[0070] S2314, determine first analysis information according to the touch waveform of the touched object.

[0071] Exemplarily, the periodic change reflects the touch waveform of the touched object, and the touch waveform of the touched object is determined as the first analysis information.

[0072] S232, perform a mechanical feature pattern analysis on the touched object near the electronic fence to obtain second analysis information; wherein, the second analysis information is used to reflect the deformation situation of the fence caused by the touched object, and there is an electronic fence at the position of the fence.

[0073] Exemplarily, it can be achieved by setting a pressure sensor or a strain gauge. The pressure sensor or the strain gauge can detect the pressure or deformation caused by the touched object on the electronic fence, and convert these signals into electrical signals for transmission. Specifically, when the touched object contacts the electronic fence, certain pressure and deformation will be generated, which will be captured by the pressure sensor or the strain gauge and converted into corresponding electrical signals. Then, based on these electrical signals, information about the deformation situation of the fence caused by the touched object, that is, the second analysis information, can be obtained.

[0074] In a possible implementation, please refer to Figure 5 , S232, perform a mechanical feature pattern analysis on the touched object near the electronic fence to obtain second analysis information, including: S2321, detect multiple pressure points on the fence in real time; wherein, the multiple pressure points are obtained by the touched object touching the fence.

[0075] It can be understood that multiple pressure points are obtained when the touching object touches the enclosure. It can be understood that after the enclosure is touched, multiple pressure points are formed between the enclosure and the touching object. The real-time detection method can be realized by setting multiple pressure sensors on the enclosure; the pressure sensors can capture the pressure signals generated by the touching object on the enclosure in real time, and convert these signals into electrical signals for transmission to the control device. Specifically, when the touching object contacts the enclosure, a certain pressure will be generated at the contact point, and this pressure will be captured by the pressure sensor and converted into corresponding electrical signals.

[0076] S2322, obtain the formation time of each pressure point based on multiple pressure points; wherein, the formation time of the pressure point is the time when the touching object touches the enclosure.

[0077] Exemplarily, the formation time of each pressure point can be recorded by a timestamp. When the touching object contacts the enclosure, the pressure sensor will immediately capture the pressure signal and record the timestamp at this time, that is, the formation time of the pressure point, and the timestamp can be used for subsequent analysis preparation.

[0078] S2323, obtain the touching path of the touching object according to the time sequence of each pressure point; wherein, the touching path is a path formed by connecting each pressure point in sequence according to the sequence of the formation times of each pressure point.

[0079] Exemplarily, the movement trajectory of the touching object on the enclosure, that is, the touching path, can be determined by analyzing the time sequence of the pressure points. Specifically, sort each pressure point according to the sequence of its formation time, and then connect these pressure points in sequence to obtain the movement path of the touching object on the enclosure. Its touching path reflects the dynamic process of the touching object contacting the enclosure and can be used to further analyze the behavioral characteristics of the touching object, such as climbing, etc. By analyzing the characteristics such as the shape, length, and direction of the touching path, the movement state and behavioral intention of the touching object can be understood more deeply, so as to provide more accurate information for subsequent judgment.

[0080] S2324, generate a pressure heat map based on the touching path, and obtain second analysis information according to the pressure heat map.

[0081] Exemplarily, the pressure values of each pressure point on the touch path can be visualized to generate a pressure heat map. The pressure heat map can intuitively display the pressure distribution of the touched object on the fence, that is, the magnitude of the pressure received by different regions. Information about the deformation of the fence caused by the touched object, that is, the second analysis information, can be obtained through the pressure heat map. For example, if the pressure heat map shows that a certain area receives a large pressure and for a long time, it may mean that the touched object climbs or applies a large force in this area, which helps to more accurately judge the type and behavioral characteristics of the touched object.

[0082] With such a setting, potential intrusion events can be detected and processed in a timely manner, improving the security protection ability of the electronic fence. At the same time, by analyzing the characteristics of the touched object in detail, the alarm information can be further enriched, providing a more comprehensive description of the intrusion event for the monitoring center or security personnel and enabling faster response and decision-making.

[0083] S233, obtain the second information according to the first analysis information and the second analysis information.

[0084] Exemplarily, the distribution of the vibration signal indicated by the first analysis information and the deformation of the fence caused by the touched object indicated by the second analysis information are determined as the second information.

[0085] With such a setting, a more comprehensive and accurate judgment of the touched object can be made by integrating the vibration signal and mechanical characteristics, etc. By comparing and analyzing the characteristics in the first analysis information and the second analysis information, the type and behavior of the touched object can be further confirmed, such as whether it is an animal, a human or other object, and its behavioral characteristics, such as climbing, running or staying still, etc., which can improve the security and reliability of the electronic fence system, reduce false alarms and missed alarms, and provide more effective support for security protection.

[0086] In a possible implementation manner, please refer to Figure 3 , the method further includes: If the touched object reflected by the judgment information is a false touch situation, obtain false touch record information; wherein, the false touch record information is used to indicate the time of false touch, the duration of false touch and the number of touches.

[0087] Exemplarily, the false touch recording can be performed by a false touch judgment module, and the recording can be carried out through the false touch judgment module. Specifically, when it is determined that the touching object is a false touch situation such as an animal or a plant, the false touch judgment module will immediately activate the recording function and record information such as the time when the false touch occurs, the duration of the false touch, and the number of touches. Among them, the false touch judgment module can be a dedicated software component, which is communicatively connected to the control device and is part of the electronic fence intrusion detection device; in addition, the false touch judgment module can also continuously optimize and adjust the judgment logic according to historical data and statistical analysis results to adapt to false touch situations under different environments and conditions, and improve the accuracy and reliability of the judgment.

[0088] With such a setting, by analyzing the false touch record information, the high-incidence time periods and areas of false touch events can be understood, so as to make targeted adjustments and optimizations to reduce the occurrence of false touch situations. At the same time, the false touch record information can also provide reference for security personnel, enabling them to more accurately judge and handle intrusion events, and improving the efficiency and accuracy of security protection.

[0089] S240, determine the touch information according to the second information.

[0090] Exemplarily, determine the form condition of the touching object reflected by the second information as the touch information.

[0091] With such a setting, the situation of the touching object can be more comprehensively reflected, providing a basis for subsequent processing and judgment. For example, if the touching object presents a specific shape or size, it may match the known intruder characteristics, thereby further improving the accuracy of intrusion detection.

[0092] S300, determine the intrusion information according to the situation of the touching object that touches the electronic fence indicated by the touch information; where the intrusion information is used to indicate whether there is an intrusion by a person or an animal.

[0093] Exemplarily, determine the touching object that touches the electronic fence indicated by the touch information, and determine whether there is an intrusion by a person or an animal according to the situation (person, animal, plant, etc.) of the determined touching object.

[0094] With such a setting, not only can it be detected that there is an object touching, but also the specific situation and type of the touching object can be judged, accurately judging whether there is an intrusion by a person, reducing the situations of false alarms and missed alarms, and improving the security and reliability of the protected area of the electronic fence.
