Description

Technical Field

[0001] This invention belongs to the field of electronic fence technology, specifically an electronic fence and its control method. Background Technology

[0002] An electronic fence is a modern perimeter security product. Its working principle is to generate a high-voltage electric field on the fence line by a pulse signal emitted by the host. When an intruder touches or approaches the fence line, it will change the distribution of the electric field, thereby triggering an alarm.

[0003] The barriers on existing electronic fences are usually fixed to the fence posts, and the spacing between the top and bottom of the barriers is fixed and cannot be adjusted. Intruders can study or try to find a position with a larger gap between the barriers and then crawl through the gaps to successfully break through the fence's protection and enter the protected area, causing the electronic fence's protective function to fail. Summary of the Invention

[0004] The purpose of this invention is to address the problem that the fixed ropes on existing electronic fences cannot be adjusted, allowing intruders to enter the protected area through gaps in the ropes, thus rendering the electronic fence's protective function ineffective. This invention provides an electronic fence and its control method.

[0005] The technical solution adopted in this invention is as follows:

[0006] An electronic fence includes:

[0007] The column body has symmetrically arranged sliding holes on both sides, and the column processor and the sound and light alarm are fixedly installed on the adjacent sides of the upper end of the column body respectively.

[0008] A rope spacing adjustment mechanism includes several movable boxes slidably installed at equal intervals within a column body. Each movable box has two rope-blocking bodies at both ends, and each rope-blocking body passes through two sliding holes. A U-shaped fixing plate is fixedly installed at the bottom of the column body. Transmission rods are rotatably installed on both sides of the U-shaped fixing plate and both sides of the movable boxes. The connections between the transmission rods are hinged together. A round rod is fixedly installed between the transmission rods on both sides of the U-shaped fixing plate. The two ends of the round rod pass through both sides of the U-shaped fixing plate and are rotatably connected to it. A ring gear is fixedly installed on the round rod. A first cylinder is fixedly installed at the bottom of the U-shaped fixing plate. The first cylinder has a first trigger. A first long toothed rod is fixedly connected to the telescopic end of the first cylinder, and the first long toothed rod meshes with the ring gear.

[0009] The movable box has round holes on both sides, and a rotating rod is rotatably installed between the inner walls of the movable box. The lower end of the rotating rod passes through the lower end of the movable box, and a rotating wheel is fixedly installed on the rotating rod. Both sides of the rotating wheel are provided with rope-blocking fixing mechanisms, and the bottom of the movable box is provided with a rope-blocking tensioning mechanism.

[0010] The rope-stopping mechanism includes a connecting box fixedly installed on the surface of the rotating wheel, a clamping plate slidably installed inside the connecting box, a second cylinder fixedly installed on one side of the connecting box, the telescopic end of the second cylinder passing through one side of the connecting box and fixedly connected to the clamping plate, the end of the rope-stopping body passing through a round hole and set inside the connecting box, and a second trigger provided on the second cylinder.

[0011] The rope tensioning mechanism includes a circular gear fixedly connected to the lower end of the rotating rod. The bottom of the movable box is provided with a second long toothed rod that meshes with the circular gear. A fixing block is fixedly connected to one side of the second long toothed rod. A third cylinder is fixedly installed at the lower end of the movable box. A third trigger is fixedly installed on the third cylinder. The telescopic end of the third cylinder is fixedly connected to the fixing block.

[0012] The bottom of the movable box is fixedly connected to an L-shaped limiting rod, and a limiting hole is opened on one side of the L-shaped limiting rod. The second long toothed rod and the fixing block are respectively slidably installed in the L-shaped limiting rod and the limiting hole.

[0013] The lower end of the column body is fixedly connected to a mounting base.

[0014] A control method for an electronic fence includes the following steps: First, connect the control terminal to the fence host, turn on the host power, set the initial spacing of the barrier ropes and pulse signal parameters in the terminal software, and save them to the host storage unit. Start the host self-test program to check whether the relevant equipment modules are normal. If there is a fault, send fault information to the preset terminal through the audible and visual alarm. Then, enter the spacing adjustment interface of the terminal, input the rising or falling height value or the target spacing to make the spacing of the barrier ropes change accordingly. Then, the signal generation module continuously sends pulse high-voltage signals to the barrier ropes. When an object approaches or touches the barrier ropes, the electric field changes. The signal detection and control module transmits the changed signal to the column processor. The column processor analyzes the signal change amplitude, duration, frequency, etc. according to the preset algorithm. If it determines that there is an intrusion, it triggers the audible and visual alarm. At the same time, it sends alarm information to the monitoring center server through the communication module. Finally, inspect the stability of the fence columns, the status of the barrier ropes, the performance of the spacing adjustment device, the function of the alarm device, the communication status of the communication module, etc., according to the preset cycle, record the problems, and then adjust the system parameters according to the actual situation. The host storage data is backed up and analyzed regularly, and the security strategy is optimized based on the analysis results.

[0015] In this system, the user accesses the rope spacing adjustment interface through a control terminal connected to the electronic fence system. In this interface, the user inputs the required vertical rope spacing value or directly sets the rising and falling height value. The control terminal sends the user's input command to the column processor. After receiving the command, the column processor calculates the relevant parameters of the first cylinder according to the preset program and algorithm, and then generates the corresponding first cylinder control signal. Then, it sends a signal to the first trigger on the first cylinder to drive the first cylinder to start, causing the spacing between several moving boxes to change.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0017] In this invention, a rope spacing adjustment mechanism is employed. When adjusting the spacing between the ropes, the required vertical spacing value or the rising and falling height value is set via a control terminal. The control terminal then sends the user-input command to the column processor. Upon receiving the command, the column processor sends a command to the first trigger of the first cylinder, causing the first cylinder to pull the first long toothed rod downwards. This further causes the ring gear to drive the round rod to rotate, resulting in the rotation of the two transmission rods at both ends of the U-shaped fixed plate. Through the transmission of several transmission rods, several moving boxes slide downwards sequentially within the column body. Then, the transmission rods at both ends of the moving boxes rotate on both sides of the moving boxes, reducing the distance between the moving boxes and thus changing the spacing between the rope bodies, thereby improving the protective function of the fence.

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0027] Reference Figures 1-5 An electronic fence includes a post body 10, with symmetrically arranged sliding holes 101 on both sides of the post body 10. A post processor 11 and an audible and visual alarm 12 are fixedly installed on adjacent sides of the upper end of the post body 10, respectively. The post body 10 contains a rope spacing adjustment mechanism, which includes several movable boxes 20 slidably installed at equal intervals within the post body 10. Each movable box 20 has two rope-blocking bodies 13 at both ends, and each rope-blocking body 13 passes through two sliding holes 101. A U-shaped fixing plate 22 is fixedly installed at the bottom of the post body 10. The two ends of the U-shaped fixing plate 22... A transmission rod 21 is rotatably mounted on both sides of several movable boxes 20. The connections between the transmission rods 21 are all hinged to each other. A round rod 23 is fixedly mounted between the transmission rods 21 on both sides of the U-shaped fixed plate 22. The two ends of the round rod 23 pass through both sides of the U-shaped fixed plate 22 and are rotatably connected to the U-shaped fixed plate 22. A ring gear 24 is fixedly mounted on the round rod 23. A first cylinder 26 is fixedly mounted on the bottom of the U-shaped fixed plate 22. A first trigger 261 is provided on the first cylinder 26. A first long toothed rod 25 is fixedly connected to the telescopic end of the first cylinder 26. The first long toothed rod 25 meshes with the ring gear 24.

[0028] Specifically, when adjusting the spacing between the rope-stopping bodies 13, the control terminal sends the user-input command to the column processor 11. After receiving the command, the column processor 11 sends a command to the first trigger 261 of the first cylinder 26 to drive the first cylinder 26 to pull the first long toothed rod 25 downward, further causing the ring gear 24 to drive the round rod 23 to rotate, causing the two transmission rods 21 at both ends of the U-shaped fixing plate 22 to rotate along the circumference of the round rod 23. After being driven by several transmission rods 21, several moving boxes 20 are driven to slide downward in sequence within the column body 10. Then, the transmission rods 21 at both ends of several moving boxes 20 rotate on both sides of the moving boxes 20, making the distance between several moving boxes 20 smaller, thereby changing the spacing between the rope-stopping bodies 13.

[0029] Reference Figure 3 and Figure 4 As shown, the movable box 20 has round holes 201 on both sides to facilitate the insertion of the end of the rope body 13. A rotating rod 30 is rotatably installed between the inner walls of the movable box 20. The lower end of the rotating rod 30 passes through the lower end of the movable box 20. A rotating wheel 31 is fixedly installed on the rotating rod 30. Rope fixing mechanisms are provided on both sides of the rotating wheel 31. A rope tensioning mechanism is provided at the bottom of the movable box 20.

[0030] Reference Figure 2 and Figure 3 As shown, the rope-stopping mechanism includes a connecting box 311 fixedly installed on the surface of the rotating wheel 31. A clamping plate 32 is slidably installed inside the connecting box 311. A second cylinder 33 is fixedly installed on one side of the connecting box 311. The telescopic end of the second cylinder 33 passes through one side of the connecting box 311 and is fixedly connected to the clamping plate 32. The end of the rope-stopping body 13 passes through the round hole 201 and is located inside the connecting box 311. A second trigger 331 is provided on the second cylinder 33. When the rope-stopping body 13 inside the column body 10 is disassembled, the fence terminal sends a command to the second trigger 331 through the column processor 11. The second trigger 331 drives the second cylinder 33 to pull the clamping plate 32 away from the end surface of the rope-stopping body 13, releasing the fixation of the end of the rope-stopping body 13, so as to facilitate the removal of the rope-stopping body 13 from the column body 10.

[0031] Reference Figure 4As shown, the rope tensioning mechanism includes a spur gear 301 fixedly connected to the lower end of the rotating rod 30. The bottom of the movable box 20 is provided with a second long toothed rod 34, which meshes with the spur gear 301. A fixing block 341 is fixedly connected to one side of the second long toothed rod 34. A third cylinder 35 is fixedly installed at the lower end of the movable box 20. A third trigger 351 is fixedly installed on the third cylinder 35. The telescopic end of the third cylinder 35 is fixedly connected to the fixing block 341. When tensioning the rope bodies 13 at both ends of the column body 10, the fence terminal sends a command to the third trigger 351 through the column processor 11. The third trigger 351 drives the second cylinder 33 to pull the fixing block 341 to slide within the limiting hole 203, causing the second long toothed rod 34 to drive the spur gear 301 to rotate. This further causes the rotating wheel 31 to drive the ends of the rope bodies 13 at both ends to move along the rotation direction of the rotating wheel 31, thus changing the tension of the rope bodies 13 at both ends of the movable box 20.

[0032] Reference Figure 4 As shown, an L-shaped limiting rod 202 is fixedly connected to the bottom of the movable box 20. A limiting hole 203 is opened on one side of the L-shaped limiting rod 202. The second long toothed rod 34 and the fixing block 341 are slidably installed in the L-shaped limiting rod 202 and the limiting hole 203, respectively. The L-shaped limiting rod 202 limits the position of the second long toothed rod 34 to prevent the second long toothed rod 34 from disengaging from the spur gear 301 when it moves.

[0033] Reference Figure 1 As shown, the lower end of the column body 10 is fixedly connected to the mounting base 102, and the mounting base 102 has mounting holes to facilitate the installation of the column body 10 on the wall.

[0034] A control method for an electronic fence includes the following steps: First, connect the control terminal to the fence host, turn on the host power, set the initial spacing of the barrier ropes and pulse signal parameters in the terminal software, and save them to the host storage unit. Start the host self-test program to check whether the relevant equipment modules are normal. If there is a fault, send fault information to the preset terminal through the audible and visual alarm 12. Then, enter the spacing adjustment interface of the terminal, input the rising or falling height value or the target spacing to make the spacing of the barrier ropes change accordingly. Then, the signal generation module continuously sends pulse high voltage signals to the barrier ropes. When an object approaches or touches the barrier ropes, the electric field changes. The signal detection and control module transmits the change signal to the column processor 11. The column processor 11 analyzes the signal change amplitude, duration, frequency, etc. according to the preset algorithm. If it determines that there is an intrusion, it triggers the audible and visual alarm 12 to alarm. At the same time, it sends alarm information to the monitoring center server through the communication module. Finally, inspect the stability of the fence columns, the status of the barrier ropes, the performance of the spacing adjustment device, the function of the alarm device, the communication status of the communication module, etc., according to the preset cycle, record the problems, and then adjust the system parameters according to the actual situation. The host storage data is backed up and analyzed regularly, and the security strategy is optimized based on the analysis results.

[0035] In detail, when the equipment starts its self-test, the self-test program first activates the signal generation module. The signal generation module generates a test pulse signal to check whether it can generate a pulse signal that meets the set parameters. It also internally monitors the generated signal to check the accuracy of the pulse voltage, width, and frequency. If there is a deviation, the error information is recorded. The signal detection and control module then sends a low-intensity detection signal to the rope to determine whether there is an open circuit or short circuit in the rope. If an abnormality is detected, the fault location and type information will be displayed on the host display screen or software interface. Next, the rope spacing adjustment mechanism, rope fixing mechanism, and rope tensioning mechanism are tested to check whether the operation is smooth and whether there is any jamming or abnormal noise in the internal components. If any problem is found during the self-test, the system will issue an alarm sound and flashing light through the audible and visual alarm 12. At the same time, it will send fault information to the preset terminal through the communication module, detailing the fault location and type. If the self-test is all normal, the system enters the standby state and waits for subsequent operation instructions.

[0036] Reference Figure 5As shown, when adjusting the rope spacing, the user enters the rope spacing adjustment interface through the control terminal connected to the electronic fence system. In this interface, the user inputs the required vertical rope spacing value or directly sets the rising and falling height values. The control terminal sends the user's input command to the column processor 11. After receiving the command, the column processor 11 calculates the relevant parameters of the first cylinder 26 according to the preset program and algorithm, and then generates the corresponding control signal for the first cylinder 26. Then, it sends a signal to the first trigger 261 on the first cylinder 26 to drive the first cylinder 26 to start, so that the spacing between the several moving boxes 20 changes, thereby changing the vertical rope spacing. Furthermore, the electronic fence can flexibly reduce the spacing between the rope bodies 13 according to the actual situation, effectively filling these potential protection loopholes, greatly improving the overall protection capability of the fence, and reducing the possibility of successful intrusion.

[0037] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
