Description

Technical Field

[0001] The present invention relates to the technical field of fence security, and in particular to a tension fence with a climbing alarm function. Background Art

[0002] A tension fence is a common device used to set up a perimeter to prevent people or other organisms from entering a specific area, usually set up around specific places such as factory areas and campuses to ensure the safety and stability inside these places. However, common tension fences only have basic physical interception functions, and their safety levels cannot meet the requirements of some special places, such as airports and nuclear power plants. To solve this problem, some improvements have been made to the existing tension fences.

[0003] For example, the prior art with the publication number CN219066222U discloses a perimeter alarm system for a tension fence with a climbing monitoring function. The system includes a tension host, a support rod, and a terminal rod. A tension control board and a tension module are arranged inside the tension host, and an anti-climbing module is also arranged inside the tension host. A nine-axis sensor connected to the tension control board through a group of power supplies and signal lines is arranged inside the anti-climbing module, and the tension control board is connected to an alarm host through an explosion-proof box and a circuit. The system monitors the climbing situation of the tension host in real time, enhances the protection of the tension host, and an alarm will also occur if an outsider uses the host as a pedal.

[0004] However, this prior art still has defects. For example, the system is easily interfered by non-human external forces during operation, causing the system to misjudge that someone is climbing in some cases and issue false alarms, and its detection accuracy is not high and its stability is not good.

[0048] As Figure 1 shown, the tension fence with a climbing alarm function proposed by the present invention includes:

[0049] A fence base layer 100, which is jointly enclosed by a plurality of node units 110 and fence units 120 distributed between adjacent node units 110;

[0050] A sensing and detection layer 200, installed on the fence base layer 100, for detecting changes in the external force applied to the fence base layer 100;

[0051] A central execution layer 300, including a central control unit 310 and an action execution unit 320, for judging whether a climbing behavior occurs on the fence base layer 100 according to the detection result of the sensing and detection layer 200, so as to execute corresponding preset actions.

[0052] As Figure 2 shown, based on the structures and functions of the above-mentioned sensing and detection layer 200 and central execution layer 300, the tension fence with a climbing alarm function of the present invention will perform the following steps when working:

[0053] Step S10: Obtain the change in the external force applied to the fence base layer 100;

[0054] Step S20: Judge whether a climbing behavior occurs on the fence base layer 100 according to the change in the external force on the fence base layer 100;

[0055] Step S30: Execute corresponding preset actions according to the judgment result.

[0056] For the convenience of description and understanding, the technical features of the sensing and detection layer 200 and the central execution layer 300 and the steps they perform during operation will be further explained in specific embodiments below.

[0057] Specifically in the embodiments, the sensing and detection layer 200 installed on the fence base layer 100 will detect in real time whether the fence unit 120 on the fence base layer 100 is affected by an external force, as well as the magnitude and change of the external force received when it is determined that an external force is applied. Data transmission and exchange between the sensing and detection layer 200 and the central execution layer 300 are achieved through communication connection or directly through circuit connection. Based on this, after detecting the change data of the external force applied to the fence base layer 100, the sensing and detection layer 200 will transmit the change data of the external force to the central execution layer 300. After obtaining the change data of the external force applied to the fence base layer 100, the central control unit 310 in the central execution layer 300 will determine whether a climbing behavior has occurred on the fence base layer 100 based on the change of the external force on the fence base layer 100. Then, the central control unit 310 will issue a control command and / or other data to the action execution unit 320 according to the judgment result, driving the action execution unit 320 to execute corresponding preset actions.

[0058] Among them, the above-mentioned action execution unit 320 can be understood as including one or more of an alarm device, a photographing device, and a display device, and the above-mentioned preset actions vary depending on the devices and equipment. For example, when the action execution unit 320 is an alarm device, the above-mentioned preset action is to emit an alarm sound. When the action execution unit 320 is a photographing device, the above-mentioned preset action is to photograph the pictures of the node unit 110 and the vicinity of the fence unit 120. When the action execution unit 320 is a display device, the above-mentioned preset action is to display a warning picture and / or the picture taken by the photographing device, etc.

[0059] When the central control unit 310 determines whether a climbing behavior has occurred on the fence base layer 100 based on the change of the external force on the fence base layer 100, it will issue a control command and / or other data to the above-mentioned alarm device, display device, photographing device, etc., to make them start working.

[0060] Among them, the above-mentioned fence base layer 100 can be understood as a conventional fence-type protection mechanism. Among them, the node unit 110 can be understood as a vertical pole or vertical pile in a common fence-type protection mechanism, mainly playing a role in fixing and supporting, and multiple vertical poles together form the basic framework of the fence base layer 100. The above-mentioned fence unit 120 can be understood as a fence component in a common fence-type protection mechanism, and the fence component can be composed of multiple crossbars. The two ends of each crossbar are respectively fixedly connected to the vertical poles on both sides of the fence unit 120, and together with the vertical poles, they play a basic physical blocking function.

[0061] In addition to the technical features of the above-mentioned fence base layer 100, sensing and detection layer 200, and central execution layer 300, such as Figure 1 and Figure 4As shown, the basic solution of the tension fence with a climbing alarm function according to the present invention further includes the following technical features:

[0062] The sensing and detection layer 200 includes:

[0063] The primary detection unit 210, including a morphological change component 211 and a degree monitoring component 212, is used to make a deformation reaction to the external force applied to the fence base layer 100 and detect the degree of the deformation reaction;

[0064] The secondary detection unit 220, including an electrical induction component 221 and a circuit monitoring component 222; when the degree of the deformation reaction exceeds a preset degree, the electrical induction component 221 starts to work to make an electrical reaction to the external force applied to the fence base layer 100, and the circuit monitoring component 222 is used to detect the change of the electrical reaction.

[0065] As Figure 3 shown, based on the structures and functions of the above-mentioned primary detection unit 210 and secondary detection unit 220, the tension fence with a climbing alarm function according to the present invention will perform the following steps during operation:

[0066] Step S100: Obtain the degree of the deformation reaction caused by the external force applied to the fence base layer 100;

[0067] Step S200: Determine whether the degree of the deformation reaction exceeds a first preset value;

[0068] Step S300: If it exceeds the first preset value, obtain the degree of the change of the electrical reaction caused by the external force applied to the fence base layer 100;

[0069] Step S400: Determine whether the degree of the change of the electrical reaction exceeds a second preset value;

[0070] Step S500: If it exceeds the second preset value, determine that a climbing behavior has occurred on the fence base layer 100 and perform a corresponding preset action.

[0071] For the convenience of description and understanding, the following further explains and illustrates the technical features of the above-mentioned sensing and detection layer 200 and central execution layer 300, as well as the structure of the above-mentioned fence base layer 100 and the steps they perform during operation, in specific embodiments.

[0072] Specifically in the embodiments, the primary detection unit 210 and the secondary detection unit 220 are respectively connected to the central control unit 310 in the central execution layer 300 through communication connections or directly through circuit connections to achieve data transmission and exchange between the two. The primary detection unit 210 installed on the fence base layer 100 will react to the external force applied to the fence base layer 100 in real time by deforming and detect the degree of the deformation reaction, and then transmit the degree data of the deformation reaction to the central control unit 310. After the central control unit 310 obtains the degree data of the deformation reaction caused by the external force applied to the fence base layer 100, it will judge whether the degree of the deformation reaction exceeds a first preset value. If it exceeds the first preset value, the central control unit 310 will send a control instruction to the secondary detection unit 220 to drive it to work. The secondary detection unit 220 starts to detect the degree of change in the electrical reaction caused by the external force applied to the fence base layer 100, and then transmits the degree data of the change in the electrical reaction to the central control unit 310. After the central control unit 310 obtains the degree data of the change in the electrical reaction caused by the external force applied to the fence base layer 100, it will judge whether the degree of change in the electrical reaction exceeds a second preset value. If it exceeds the second preset value, the central control unit 310 will judge that a climbing behavior has occurred on the fence base layer 100 and send a control instruction to the action execution unit 320 to drive it to execute the corresponding preset action.

[0073] In a more specific embodiment, the form change component 211 installed on the fence base layer 100 will react to the external force applied to the fence base layer 100 in real time by deforming. After that, the degree monitoring component 212 connected to the form change component 211 will detect the degree of the deformation reaction, and then transmit the degree data of the deformation reaction to the central control unit 310. After the central control unit 310 obtains the degree data of the deformation reaction caused by the external force applied to the fence base layer 100, it will judge whether the degree of the deformation reaction exceeds a first preset value. If it exceeds the first preset value, the central control unit 310 will send a control instruction to the secondary detection unit 220 to drive it to work. The electrical induction component 221 starts to detect the electrical reaction caused by the external force applied to the fence base layer 100. After that, the circuit monitoring component 222 connected to the electrical induction component 221 starts to detect the degree of change in the electrical reaction, and then transmits the degree data of the change in the electrical reaction to the central control unit 310. After the central control unit 310 obtains the degree data of the change in the electrical reaction caused by the external force applied to the fence base layer 100, it will judge whether the degree of change in the electrical reaction exceeds a second preset value. If it exceeds the second preset value, the central control unit 310 will judge that a climbing behavior has occurred on the fence base layer 100 and send a control instruction to the action execution unit 320 to drive it to execute the corresponding preset action.

[0074] Among them, the above electrical reaction can be a current change, a potential change, a resistance change, etc. The electrical induction component 221 is an electrical component that will undergo a current change, a potential change, or a resistance change when subjected to an external force. Correspondingly, the circuit monitoring component 222 can detect the current change, potential change, or resistance change of the electrical induction component 221 or the circuit where it is located.

[0075] Of course, when the primary detection unit 210 responds to the external force applied to the fence base layer 100 and completes the detection of the degree of the deformation response, it is not limited to the central control unit 310 being able to obtain this data. The secondary detection unit 220 can also be configured to be associated with the primary detection unit 210. When the primary detection unit 210 responds to the external force applied to the fence base layer 100 and completes the detection of the degree of the deformation response, the primary detection unit 210 can also directly respond and start working.

[0076] In addition to the technical features of the above fence base layer 100, primary detection unit 210, secondary detection unit 220, and central execution layer 300, as Figure 5 , Figure 6 shown, the basic solution of the tension fence with a climbing alarm function of the present invention further includes the following technical features:

[0077] The fence unit 120 includes a plurality of blocking components 121. The blocking component 121 includes a rigid core 122 and a deformable housing 123. The deformable housing 123 is sleeved on the rigid core 122, and there is an installation gap between the deformable housing 123 and the rigid core 122;

[0078] The form change component 211 and the electrical induction component 221 are both disposed inside the deformable housing 123, and the degree monitoring component 212 and the circuit monitoring component 222 are both installed on the node unit 110.

[0079] For the convenience of description and understanding, the following further explains the technical features of the above fence unit 120, form change component 211, and electrical induction component 221.

[0080] The blocking component 121 can be understood as the horizontal rail in a common fence. The rigid core 122 can be a hollow or solid metal rod-shaped member, such as a steel pipe, which is used to play a basic physical blocking role. The deformable housing 123 can be understood as the outer skin layer made of plastic or rubber, and this outer skin layer wraps around the outer surface of the metal rod-shaped member. During assembly, there is an installation gap between the inner surface of the outer skin layer and the metal rod-shaped member, which is used to accommodate the shape-changing component 211 and / or the electrical induction component 221. The shapes of the shape-changing component 211 and the electrical induction component 221 are similar to the above-mentioned metal rod-shaped member, presenting an elongated strip or rod shape. The shape-changing component 211 and the electrical induction component 221 run across the fence unit 120 and are respectively connected in a matching manner with the degree monitoring component 212 and the circuit monitoring group provided on the node unit 110.

[0081] Among them, as Figure 10 , Figure 11 shown, the degree monitoring component 212 and the circuit monitoring component 222 are installed on the node unit 110 through the assembly box 130. The assembly box 130 is a box-shaped structure with one end open;

[0082] The shape-changing component 211 includes a traction member 213 located in the installation gap. The degree monitoring component 212 includes a rotating shaft member 214, a torsion spring 215 and an angle trigger device 216 installed on the rotating shaft member 214. The end of the traction member 213 extends and winds around the rotating shaft member 214;

[0083] During installation, the open end of the assembly box 130 is buckled on the node unit 110 to form a closed installation cavity. The rotating shaft member 214 is located in the installation cavity and installed on the assembly box 130. One end of the torsion spring 215 abuts against the node unit 110, and the other end of the torsion spring 215 abuts against the inner wall of the assembly box 130; under the action of the torsion spring 215, the traction member 213 is in a taut straight state.

[0084] Among them, as Figure 5 , Figure 9 , Figure 10 shown, the above-mentioned assembly box 130 can be fixedly installed on the node unit 110 by the cooperation of nuts and screw holes.

[0085] Specifically in the embodiment, on the two outer side walls of the assembly box 130 that are opposite to each other and close to the open end, there is an outer ear respectively. On the node unit 110, there are screw holes that match the aperture, quantity and installation position of the outer ears on the assembly box 130. The stud of the nut passes through the outer ear and is screwed into the screw hole on the node unit 110, and finally the assembly box 130 is firmly installed on the node unit 110.

[0086] The above-mentioned traction member 213 can be understood as a traction rope. Under normal conditions, under the action of the rotating shaft member 214 and the torsion spring 215, the traction rope in the installation gap between the deformable housing 123 and the rigid core 122 is in a taut straight state. When the fence unit 120 in the fence base layer 100 is subjected to an external force, that is, when the railing of the fence is climbed and held by a person, the deformable housing 123 will be deformed by the external force. After that, the form change component 211, that is, the traction rope, will be deformed by the extrusion of the inner wall of the deformable housing 123, changing from a taut straight state to a bent state. Then, the rotating shaft member 214 will be rotated by the traction of the traction rope wound thereon, and the angle triggering device 216 will detect the rotation angle of the rotating shaft member 214 in real time.

[0087] Specifically in the embodiment, when the rotation angle of the rotating shaft member 214 detected by the angle triggering device 216 exceeds the preset angle value, it is determined that the deformation reaction degree exceeds the first preset value, and the central control unit 310 sends a control instruction to the secondary detection unit 220 to drive it to work. The electrical induction component 221 starts to detect the electrical reaction caused by the external force applied to the fence base layer 100. After that, the circuit monitoring component 222 connected to the electrical induction component 221 starts to detect the change degree of the electrical reaction. If the change degree of the electrical reaction exceeds the second preset value, the central control unit 310 determines that a climbing behavior has occurred on the fence base layer 100 and sends a control instruction to the action execution unit 320 to drive it to execute the corresponding preset action.

[0088] In addition, when someone tries to damage the detection function of the fence by removing the assembly box 130 from the node unit 110, due to the removal of the assembly box 130, the two ends of the torsion spring 215 respectively abutting against the inner wall of the assembly box 130 and the surface of the node unit 110 will lose their restraint. The rotating shaft member 214 will rotate when the torsion spring 215 returns to its original shape, and the rotation angle of the rotating shaft member 214 detected by the angle triggering device 216 will ultimately exceed the preset angle value, that is, the deformation reaction degree exceeds the first preset value. The central control unit 310 sends a control instruction to the secondary detection unit 220 to drive it to work, and finally sends a control instruction to the action execution unit 320 to drive it to execute the corresponding preset action, such as alarming.

[0089] In a technical solution, the angle triggering device 216 includes an angle sensor. When the angle sensor detects that the rotation angle of the rotating shaft member 214 exceeds the preset angle value, the electrical induction component 221 and the circuit monitoring component 222 start to work.

[0090] Specifically in the embodiment, when the fence unit 120 in the fence base layer 100 is subjected to an external force, that is, when the railing of the fence is climbed and held by a person, the deformable housing 123 will be deformed by the external force. After that, the shape change component 211, that is, the traction rope, will be deformed by the extrusion of the inner wall of the deformable housing 123, changing from a taut straight state to a bent state. Subsequently, the rotating shaft member 214 will be driven to rotate by the traction rope wound around it. The angle sensor provided on the rotating shaft member 214 will detect the rotation angle change data of the rotating shaft member 214 in real time and transmit the angle change data to the central control unit 310. When the central control unit 310 determines that the rotation angle of the rotating shaft member 214 shown in the angle change data exceeds the preset angle value, it is finally determined that the deformation reaction degree exceeds the first preset value. After that, the central control unit 310 will send a control instruction to the secondary detection unit 220 to drive it to work, and finally determine whether a climbing behavior has occurred on the fence base layer 100 based on the detection result of the secondary detection unit 220, and whether to send a control instruction to the action execution unit 320 to drive it to execute the corresponding preset action.

[0091] In another technical solution, the angle trigger device 216 includes a cam member installed at the end of the rotating shaft member 214 and a switch circuit matching the cam member; the switch circuit is connected in series with the secondary detection unit 220 and is used to control the switch of the circuit where the secondary detection unit 220 is located;

[0092] The cam member and the switch circuit are configured such that when the rotation angle of the rotating shaft member 214 reaches and exceeds the preset angle value, the outermost end of the cam member abuts against the switch of the switch circuit to turn on the switch circuit, and the electrical induction component 221 and the circuit monitoring component 222 start to work.

[0093] Specifically in the embodiment, when the fence unit 120 in the fence base layer 100 is subjected to an external force, that is, when the railing of the fence is climbed and held by a person, the deformable shell 123 will be deformed by the external force. After that, the shape change component 211, that is, the traction rope, will be deformed by the extrusion of the inner wall of the deformable shell 123, changing from a taut straight state to a bent state. Subsequently, the rotating shaft member 214 is driven to rotate by the traction rope wound thereon. The cam member provided at the end of the rotating shaft member 214 will rotate together with the rotating shaft member 214. When the rotation angle of the rotating shaft member 214 reaches and exceeds the preset angle value, the outermost end of the cam member abuts against the switch of the switch circuit to turn on the switch circuit, and the series circuit where the electrical induction component 221 and the circuit monitoring component 222 are located is turned on. Then, the electrical induction component 221 starts to detect the electrical reaction caused by the external force applied to the fence base layer 100. After that, the circuit monitoring component 222 connected to the electrical induction component 221 starts to detect the change degree of the electrical reaction and transmits the data of the change degree of the electrical reaction to the central control unit 310. After obtaining the data of the change degree of the electrical reaction caused by the external force applied to the fence base layer 100, the central control unit 310 will judge whether the change degree of the electrical reaction exceeds the second preset value. If it exceeds the second preset value, the central control unit 310 determines that a climbing behavior has occurred on the fence base layer 100 and sends a control command to the action execution unit 320 to drive it to execute the corresponding preset action.

[0094] In one of the embodiments, the cam member functions as a switch, and a conductive metal member is provided at its outermost end. When the outermost end of the cam member abuts against the switch break valve port of the switch circuit, both ends of the switch break valve port will be respectively connected to the metal member on the outermost end of the cam member, and the series circuit where the electrical induction component 221 and the circuit monitoring component 222 are located will be turned on and start to work.

[0095] In another embodiment, the cam member functions to push the switch. The switch circuit is provided with a switch break valve port, a valve port connecting member matching the switch break valve port, and a driven member connected to the valve port connecting member. The driven member will abut against the cam member and move under its push. The cam member and the driven member are configured such that when the outermost end of the cam member contacts the driven member, the valve port connecting member just moves to the switch break valve port under the push of the driven member, turning on the switch circuit.

[0096] Among them, the above-mentioned switch circuit is arranged inside the side wall of the assembly box 130, and the driven member is located in the guiding groove opened in the side wall of the assembly box 130. The opening end position of the guiding groove matches the cam member.

[0097] During the process that the outermost end of the cam member rotates and gradually approaches the follower, under the pushing action, the follower will displace in the guiding groove, thereby pushing the valve port connecting member connected thereto. When the outermost end of the cam member abuts against the follower, the valve port connecting member is pushed by the follower to the switching open / closed valve port, so that the switching circuit is turned on, and the electrical induction component 221 and the circuit monitoring component 222 start to work.

[0098] Among them, the above valve port connecting member can be understood as a metal component with electrical conductivity.

[0099] In one embodiment, the electrical induction component 221 includes a piezoelectric electrical member 224 located in the installation gap, and the circuit monitoring component 222 is connected to the piezoelectric electrical member 224 to detect the electrical changes on the piezoelectric electrical member 224 in real time.

[0100] Specifically in the embodiment, after the electrical induction component 221 and the circuit monitoring component 222 start to work, if an external force is applied to the blocking component 121 to squeeze the deformable housing 123 and the piezoelectric electrical member 224 inside it, the piezoelectric electrical member 224 will generate a potential change, and this potential change will be transmitted to the circuit monitoring component 222. The circuit monitoring component 222 will detect and identify the existence of this potential change and related parameter characteristics to determine the degree of electrical response change caused by the external force applied to the fence base layer 100. If the degree of electrical response change exceeds the second preset value, the central control unit 310 determines that a climbing behavior has occurred on the fence base layer 100 and sends a control instruction to the action execution unit 320 to drive it to execute the corresponding preset action.

[0101] Among them, the above parameter characteristics related to the potential change can include the number of point sets of the potential change and the position of the point set of the potential change on the piezoelectric electrical member 224. Usually, when a person holds the blocking component 121 with their hand, multiple fingers of one hand will each form a squeezing point to squeeze the piezoelectric electrical member 224 respectively. However, due to the characteristics of the hand, these squeezing points will be very close to each other, and the points of the potential change generated by one hand will be concentrated together. The set composed of multiple points of the potential change that are very close to each other generated by one hand is the point set of the potential change.

[0102] In one embodiment, when the circuit monitoring component 222 detects that the number of point sets of the potential change is equal to or greater than two, it is determined that the degree of electrical response change exceeds the second preset value. Then, the central control unit 310 determines that a climbing behavior has occurred on the fence base layer 100 and sends a control instruction to the action execution unit 320 to drive it to execute the corresponding preset action. Through this solution, it is possible to avoid misjudging other accidental force-bearing behaviors as someone climbing the fence, greatly improving the accuracy of identification.

[0103] Among them, the piezoelectric electrical component 224 is made of a piezoelectric material. When the piezoelectric material is deformed by an external force, the piezoelectric material will emit a potential change signal.

[0104] In another embodiment, the electrical induction component 221 includes a conductive member 225 embedded on the outer surface of the deformable housing 123, and the circuit monitoring component 222 is connected to the conductive member 225 to detect the electrical changes on the conductive member 225 in real time.

[0105] Specifically, in the embodiment, after the electrical induction component 221 and the circuit monitoring component 222 start to work, if an external force is applied to the blocking component 121, the person applying the force will directly contact the conductive member 225 on the outer surface of the deformable housing 123 in the blocking component 121, and the current on the circuit where the conductive member 225 is located will change. The circuit monitoring component 222 will detect and identify the existence of this current change to determine the degree of change in the electrical reaction caused by the external force applied to the fence base layer 100. If the difference between the degree of change in the electrical reaction and the current change exceeds the second preset value, the central control unit 310 determines that a climbing behavior has occurred on the fence base layer 100 and sends a control instruction to the action execution unit 320 to drive it to execute the corresponding preset action.

[0106] The first preset value in the above text can be understood as values of different natures according to different implementation schemes. For example, when the angle triggering device 216 is an angle sensor, the first preset value can be a preset angle value; when the angle triggering device 216 includes a cam member installed at the end of the rotating shaft member 214 and a switch circuit matching the cam member, the first preset value can be a preset angle value, or the angular displacement value that the cam member travels from the normal state to its most distal end when it abuts against the driven member, or the linear displacement value that the driven member or the valve port connecting member travels from the initial state to the moment when the switch circuit is turned on.

[0107] The second preset value in the above text can be understood as the number of potential change point sets or the current change value according to different schemes.

[0108] In one embodiment, as Figure 12 shown, the action execution unit 320 further includes a video acquisition unit 321, and the video acquisition unit 321 includes a plurality of shooting devices distributed on the node unit 110;

[0109] The number of shooting devices and their installation positions on the node unit 110 are configured such that when all the shooting devices are turned on simultaneously, the video acquisition unit 321 can acquire all the video picture information around the fence base layer 100.

[0110] Among them, the video acquisition unit 321 is connected to the central control unit 310. When the circuit monitoring component 222 detects two or more electrical change points on the electrical induction component 221, the central control unit 310 determines that a climbing behavior has occurred on the fence base layer 100, and controls the shooting device on the node unit 110 closest to the electrical change point to start collecting the video picture information in its vicinity.

[0111] In one embodiment, as Figure 12 shown, the action execution unit 320 further includes a content display end 322 for displaying the video picture information collected by the video acquisition unit 321.

[0112] Among them, the above-mentioned content display end 322 can be understood as a screen device with the ability to display dynamic text and patterns.

[0113] In addition, the content display end 322 can also output visual graphics for the data presented to the user, such as charts, animations, electronic maps, etc., to facilitate the user to understand in real time the information monitored by the tension fence with a climbing alarm function of the present invention and the current state of the fence system.

[0114] In one embodiment, as Figure 12 shown, the action execution unit 320 further includes:

[0115] The sound and light control component 323 includes a lighting device and a sound - emitting device distributed on the node unit 110, and the sound and light control component 323 is connected to the central control unit 310;

[0116] The information alarm component 324 is used to obtain the judgment result of the central control unit 310 on whether a climbing behavior has occurred on the fence base layer 100, and controls the corresponding lighting device and sound - emitting device to give a reminder according to the judgment result.

[0117] Specifically in the embodiment, when the central control unit 310 determines that a climbing behavior has occurred on the fence base layer 100, it will send a control instruction to the action execution unit 320, that is, the sound and light control component 323 and the information alarm component 324, to drive the sound and light control component 323 to emit light signals and sound signals to deter the climber, and to drive the information alarm component 324 to send out alarm information to remind the security personnel.

[0118] The technical features of the above - described embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above - described embodiments are described. However, as long as the combinations of these technical features do not conflict, they should be considered as the scope recorded in this specification.

[0119] In addition, the above-described embodiments merely represent several implementation manners of the present invention. Their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications, substitutions, and improvements can be made, and these should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the claims.
