Description

A tension-type electronic fence perimeter intrusion prevention device and method Technical Field

[0001] This invention relates to the field of perimeter security technology, specifically to a device and method for preventing perimeter intrusion using a tension-type electronic fence. Background Technology

[0002] Currently, tension-type electronic fences primarily use electronic tension sensors to detect perimeter intrusion or wire breakage by measuring tension values. When the tension value or rate of change exceeds or falls below a preset value, an intrusion alarm is triggered. Because tension-type electronic fence systems are affected by ambient temperature, the tension wires expand and contract with temperature changes. When the ambient temperature during installation differs significantly from the ambient temperature during use, it can cause a linear change in the tension wire value, affecting the accuracy of intrusion measurement. Therefore, in addition to precise adjustment of the tension wires during installation, the system requires frequent checks and calibrations of the tension wires in different seasons to ensure the tension of the tension-type electronic fence system remains within the specified range.

[0003] Problems with tension-type electronic fences that use electronic tension sensors as the detection method include: Precise adjustment of the initial tension of each fence tension wire to the design value is required during installation, and the extension length of the spring used to maintain tension must also be consistent, which demands a high level of technical skill from the installers. Frequent inspections and maintenance are necessary. Standards require that the error between the alarm response value and the set alarm threshold should not exceed ±15%. When the ambient temperature is at its lowest or highest, failure to adjust the tension of the fence tension wires will result in more false alarms, and adjusting the tension wires requires working at height, increasing the system's maintenance difficulty and cost. In summer, during rapid intrusions, the thermal expansion of the fence tension wires reduces their tension value. The tension generated by the intrusion requires greater force and a longer time to reach the alarm threshold, resulting in a very short alarm trigger time and reduced alarm accuracy in this environment. It lacks the deterrent capability of high-voltage pulse type perimeter systems. From the above problems, it can be seen that tension-type electronic fence systems that measure tension are suitable for deployment in situations where there are good inspection and maintenance capabilities and timely calibration of the fence wire tension. Summary of the Invention

[0004] This application provides a device and method for perimeter intrusion prevention using a tension-type electronic fence, which solves the problems in the prior art such as the need for frequent inspection and maintenance and the lack of deterrent capability of high-voltage pulse type perimeter systems.

[0005] The first aspect of this application provides a tension-type electronic fence perimeter intrusion prevention device, comprising: an alarm host, an automatic tensioning spring, an electronic fence tension line, a functional pole, an area management unit, and a management computer; wherein, the electronic fence tension line is connected to the automatic tensioning spring, the alarm host, and the functional pole; the alarm host is connected to the area management unit, the area management unit is connected to the management computer, and the functional pole is connected to the alarm host; the alarm host is used to detect tension changes in the electronic fence tension line and generate alarm signals, supporting wired and wireless dual-mode data transmission; the automatic tensioning spring is used to unidirectionally tighten the electronic fence tension line to counteract the effects of thermal expansion and contraction caused by temperature changes; the electronic fence tension line is used to form a detection unit, which, in conjunction with on-site electric heating and the automatic tensioning spring, completes tension calibration and performs intrusion and wire breakage detection; the functional pole provides rigid support, possesses high-voltage pulse deterrence function, and has system self-sufficient power supply capability; the area management unit is used to periodically wake up the alarm host, receive alarm signals, and forward them to the management computer, supporting IP network communication; the management computer is used for system parameter configuration, operation status monitoring, alarm information processing, and data storage management.

[0006] Preferably, the alarm host includes a tension detection unit, a signal processing unit, and a dual-mode communication unit. The tension detection unit comprises a guide gear, a belt, a detection spring, an alarm contact, a self-generating device, and a spring-assisted positioner, used to monitor the tension value of the electronic fence tension line in real time. The spring-assisted positioner ensures that the detection spring is not stressed during the heating process of the electronic fence tension line and is removed after tightening to provide a tension response. The signal processing unit corresponds to the control circuit board and is used to filter, amplify, and compare the tension change data to generate intrusion alarm or line break alarm signals. The dual-mode communication unit supports wired RS485 communication and wireless communication.

The tension visualization calibration structure uses scales and color zones on a ratchet-equipped steel strip. The scales correspond to different lengths and temperature differences. When the innermost scale is exposed and extends beyond the color zone, it indicates that the design tension has been reached. After heating to a preset temperature, the spring contracts to the theoretically calculated scale, completing the tension calibration.

[0011] Preferably, the management computer includes a parameter configuration interface, a status monitoring panel, and a database management unit. The parameter configuration interface is used to set tension thresholds, communication parameters, and alarm rules. The status monitoring panel displays the tension curve of the electronic fence tension line, the online status of the equipment, and alarm records in real time. The database management unit is used to store historical alarm data and operation logs.

[0013] A third aspect of this application provides an electronic device, including: a memory, a processor, and a computer program stored in the memory and executable on the processor. The processor executes the program to implement a tension-type electronic fence perimeter intrusion prevention method as described in the above embodiments.

[0014] A fourth aspect of this application provides a computer-readable storage medium having a computer program stored thereon, which is executed by a processor to implement a tension-type electronic fence perimeter intrusion prevention method as described in the above embodiments.

[0015] Therefore, this application includes the following beneficial effects: The embodiments of this application utilize an alarm host that captures tension changes in real time via a tension detection unit, accurately generating intrusion or wire breakage alarm signals. Combined with a wired and wireless dual-mode communication design, it ensures stable and uninterrupted data transmission, providing core signal support for protection response. The automatic tightening spring restricts the unidirectional tightening of the tension line through a one-way ratchet mechanism, and the temperature compensation module accurately offsets tension fluctuations caused by temperature changes. Combined with a visual calibration structure, it achieves precise tension calibration, ensuring the stability and accuracy of subsequent detection. The electronic fence tension line uses high-strength stainless steel wire suitable for complex environments, and when combined with a wire breakage detection mechanism, it can be used in conjunction with on-site heating. Tension calibration ensures precise intrusion and wire breakage detection, building a solid first line of defense. Functional poles with hot-dip galvanized rigid support columns provide a stable installation foundation, a high-voltage pulse generator delivers non-lethal physical deterrence, and a solar power module ensures self-sufficient outdoor operation, adapting to diverse outdoor perimeter scenarios.

[0019] The following description, with reference to the accompanying drawings, describes a device and method for perimeter intrusion prevention using a tension-type electronic fence, according to an embodiment of this application. Addressing the issue of frequent inspection and maintenance mentioned in the background art, this application provides a device for perimeter intrusion prevention using a tension-type electronic fence. In this device, an alarm host, relying on a tension detection unit, captures tension changes in real time and accurately generates intrusion or wire breakage alarm signals. Combined with a wired and wireless dual-mode communication design, it ensures stable and uninterrupted data transmission, providing core signal support for protection response. An automatic tightening spring, through a one-way ratchet mechanism, restricts the unidirectional tightening of the tension line.

This solves the problems of existing technologies, such as the need for frequent inspections and maintenance and the lack of deterrent capabilities in high-voltage pulse type perimeter systems.

[0020] Figure 1 is a structural schematic diagram of a tension-type electronic fence perimeter intrusion prevention device provided in an embodiment of this application.

[0021] This application provides a tension-type electronic fence perimeter intrusion prevention device. The system 10 includes: an alarm host 100, an automatic tensioning spring 200, an electronic fence tension line 300, a functional pole 400, an area management unit 500, and a management computer 600.

[0022] The electronic fence tension line 300 is connected to the automatic tension spring 200, the alarm host 100, and the functional pole 400. The alarm host 100 is connected to the area management unit 500, which is connected to the management computer 600. The functional pole 400 is connected to the alarm host 100. The alarm host 100 is used to detect the tension change of the electronic fence tension line and generate an alarm signal, supporting wired and wireless dual-mode data transmission. The automatic tension spring 200 is used to unidirectionally tighten the electronic fence tension line to counteract the effects of thermal expansion and contraction caused by temperature changes. The electronic fence tension line 300 is used to form a detection unit, which, together with the on-site electric heating and the automatic tension spring, completes tension calibration and performs intrusion and wire breakage detection. The functional pole 400 provides rigid support, has a high-voltage pulse deterrent function, and has the system's self-sufficient power supply capability. The area management unit 500 is used to periodically wake up the alarm host, receive alarm signals, and forward them to the management computer, supporting IP network communication. The management computer 600 is used for system parameter configuration, operation status monitoring, alarm information processing, and data storage management.

[0023] It is understood that in this embodiment, the alarm host relies on the tension detection unit to capture tension changes in real time, accurately generating intrusion or wire breakage alarm signals. Combined with a wired and wireless dual-mode communication design, it ensures stable and uninterrupted data transmission, providing core signal support for protection response. The automatic tightening spring restricts the unidirectional tightening of the tension line through a one-way ratchet mechanism, and the temperature compensation module accurately offsets tension fluctuations caused by temperature changes. Combined with a visual calibration structure, it achieves precise tension calibration, ensuring the stability and accuracy of subsequent detection. The electronic fence tension line uses high-strength stainless steel wire suitable for complex environments. Combined with a wire breakage detection mechanism, it can be used with on-site heating to complete tension calibration. Precise and accurate intrusion and disconnection detection forms the first line of defense. Functional poles with hot-dip galvanized rigid support columns provide a stable installation foundation, while a high-voltage pulse generator delivers non-lethal physical deterrence. A solar power module ensures self-sufficient outdoor operation, adapting to diverse outdoor perimeter scenarios. The area management unit saves energy with its low-power control design, coordinates the alarm host for efficient data collection via a periodic wake-up circuit, and achieves seamless interaction with the management computer via an IP network interface. The management computer enables centralized intelligent control of the entire system, allowing for convenient parameter configuration, real-time monitoring of equipment status, and rapid processing of alarm information, while also retaining historical data for easy maintenance and traceability. The organic collaboration of these components significantly improves the accuracy, stability, and intelligence of perimeter intrusion prevention, effectively reducing maintenance costs and constructing a comprehensive and reliable perimeter protection system. This addresses the problems of existing technologies, such as the need for frequent inspections and maintenance and the lack of deterrent capability in high-voltage pulse type perimeter systems.

[0024] In this embodiment of the application, the alarm host 100 includes, as shown in FIG2, a tension detection unit, a signal processing unit, and a dual-mode communication unit.

[0025] The tension detection unit consists of a guide gear, belt, detection spring, alarm contact, self-generating device, and spring auxiliary positioner. It is used to monitor the tension value of the electronic fence tension line in real time. The spring auxiliary positioner ensures that the detection spring is not stressed during the heating process of the electronic fence tension line and is removed after tightening to respond to the tension. The signal processing unit corresponds to the control circuit board and is used to filter, amplify, and compare the tension change data with thresholds to generate intrusion alarm or wire break alarm signals. The dual-mode communication unit supports wired RS485 communication and wireless communication. The wireless communication uses a proprietary communication protocol with a frequency range of 433.05~434.79MHz and is used to transmit alarm signals to the area management unit.

[0026] It is understood that the embodiments of this application can accurately monitor tension values ​​in real time through components such as guide gears and detection springs. The spring-assisted positioner can avoid the detection spring being stressed during the heating calibration process, ensuring calibration accuracy. After removal, it can respond normally to tension changes. At the same time, the self-generating device can also provide auxiliary energy for alarm triggering. The signal processing unit can effectively improve the reliability of tension change data through filtering, amplification and threshold comparison processing, accurately generate intrusion or disconnection alarm signals, and reduce false alarms and missed alarms. The dual-mode communication unit supports wired RS485 and wireless communication with a proprietary protocol at a specific frequency (433.05~434.79MHz). The dual transmission mode can ensure the stability and flexibility of alarm signal transmission, ensuring that alarm information can be transmitted to the area management unit in a timely and secure manner, providing reliable data support for subsequent alarm processing and system monitoring, and improving the accuracy, reliability and timeliness of perimeter intrusion prevention of tension-type electronic fences.

[0027] In this embodiment, the automatic tensioning spring 200 includes, as shown in Figure 3, a one-way ratchet mechanism, a temperature compensation module, and a tension visualization calibration structure.

[0028] The unidirectional ratchet mechanism restricts the electronic fence tension line to tightening only in one direction. The ratchet teeth prevent reverse movement by dropping the ratchet. The temperature compensation module uses the linear relationship between ambient temperature and the length of the electronic fence tension line to offset tension fluctuations caused by thermal expansion and contraction through spring contraction. The tension visualization calibration structure uses scales and color areas on a ratchet-equipped steel strip. The scales correspond to different lengths and temperature differences. When the innermost scale is exposed and extends out of the color area, it indicates that the design tension has been reached. After heating to the preset temperature, the spring contracts to the theoretically calculated scale, completing the tension calibration.

[0029] It is understood that the embodiments of this application, by limiting the unidirectional tightening of the tension line and blocking reverse movement, can ensure that the tension line maintains a stable tension state after tightening, avoiding tightening failure due to reverse rebound, and providing a guarantee for the stability of the fence tension. The temperature compensation module relies on the linear relationship between ambient temperature and tension line length, and accurately offsets the tension fluctuations caused by thermal expansion and contraction through spring contraction, effectively reducing the impact of ambient temperature changes on the fence tension stability and reducing the risk of false alarms and missed alarms due to abnormal tension. The tension visualization calibration structure uses the scale and color area with ratchet steel strips to clearly indicate the design tension standard status. Combined with the spring contraction to the theoretically calculated scale after heating to complete the calibration, the calibration process is intuitive, easy to understand, and convenient to operate, ensuring calibration accuracy and ensuring that the tension line is always within the preset effective detection tension range. The synergistic effect of the three significantly improves the reliability and adaptability of the automatic tightening spring, laying a solid foundation for the tension guarantee of accurate intrusion detection of electronic fences.

[0030] For example, taking the perimeter protection of an outdoor substation as an example, a certain project uses an 80-meter-long 304 stainless steel electronic fence tension line (linear expansion coefficient 16×10^-6 / ℃), designed with a static tension of 350N, suitable for extreme environments from -30℃ to 60℃. During installation, the tension is calibrated using a visual tension calibration structure. Each scale division on the ratchet-equipped steel bar corresponds to a 0.01-meter length change and a 5°C temperature difference benchmark. When the innermost yellow scale area is exposed, it indicates that the tension has reached the design value of 350N. Subsequently, the tension line is heated to a preset calibration temperature of 40°C. The temperature compensation module of the automatic spring tightens synchronously by 0.1152 meters (80m×16×10^-6 / °C×90°C temperature difference) based on the linear relationship between ambient temperature and tension line length, precisely offsetting the ±120N tension fluctuation caused by thermal expansion and contraction. Finally, the spring contracts to the theoretical scale corresponding to a length of 0.1152 meters to complete the calibration. After tightening, the ratchet immediately locks down, completely preventing the tension line from loosening in the opposite direction, keeping the tension stable in the 330N-370N range for a long time, ensuring the accuracy of intrusion detection.

[0031] In this embodiment, the electronic fence tension line 300 includes, as shown in Figure 4, a high-strength stainless steel wire and a wire breakage detection mechanism.

[0032] The electronic fence tension line includes high-strength stainless steel wire and a wire breakage detection mechanism. The high-strength stainless steel wire is used to withstand mechanical tension and environmental stress. Two adjacent wires form a detection unit, which is connected by jumper wires to form a heating circuit. During installation, it is used in conjunction with on-site electric heating and an automatic tightening spring to complete tension calibration and eliminate the influence of temperature changes on measurement accuracy. The wire breakage detection mechanism triggers an alarm through the mechanical spring contraction and the linkage of a self-generating device to detect intrusion and wire breakage.

[0033] It is understood that the high-strength stainless steel wire in this application embodiment possesses excellent mechanical tensile strength and environmental stress resistance, providing a solid physical foundation for the fence's protection. Two adjacent wires form a detection unit and a heating circuit is constructed through a jumper wire. During installation, it can work in conjunction with on-site electric heating and an automatic tightening spring to complete tension calibration, accurately offsetting the effects of thermal expansion and contraction caused by temperature changes, and completely solving the measurement accuracy deviation problem caused by temperature differences in traditional systems. The wire breakage detection mechanism is linked to the mechanical spring contraction and the self-generating device, which can quickly respond to wire breakage faults and accurately capture tension changes caused by intrusion. Even in extreme cases, it can ensure alarm triggering through self-generating power, performing reliable dual detection of intrusion and wire breakage, significantly improving the comprehensiveness, accuracy, and stability of the fence protection.

[0034] For example, taking the perimeter protection of a 220kV outdoor substation as an example, this project uses 100-meter-long 304 high-strength stainless steel wire with a diameter of 1.8mm (tensile strength ≥520N / mm², coefficient of linear expansion 16.0×10⁻). 6 Using a wire diameter of 100°C (°C) as the tension line, each pair of adjacent wires forms a detection unit, connected by copper jumpers to form a 500W heating circuit. During installation, on-site electric heating is activated, and an automatic tensioning spring calibrates the tension line. To compensate for ambient temperature differences ranging from -25°C to 55°C (maximum 80°C), heating to a preset temperature of 40°C offsets the 0.128-meter length change in 100 meters of wire caused by temperature differences, ultimately stabilizing the tension within the designed range of 300±30N, completely eliminating the influence of temperature on measurement accuracy. When an intruder cuts the wire or the tension suddenly exceeds 80N, the mechanical spring of the wire breakage detection mechanism rapidly contracts within 3 seconds, triggering a 3V stable voltage alarm from the self-generating generator. The alarm signal is simultaneously transmitted to the management host, achieving accurate dual detection of intrusion and wire breakage, ensuring reliable 24-hour perimeter protection for the substation.

[0035] In this embodiment, the functional pole 400 includes, as shown in Figure 5, a rigid support column, a high-voltage pulse generator, and a solar power supply module.

[0036] The rigid support column is made of hot-dip galvanized steel and is pre-embedded in the foundation; the high-voltage pulse generator is used to generate non-lethal high-voltage pulses for physical deterrence; the solar power module integrates photovoltaic panels and energy storage batteries to provide self-sufficient power for the pole's auxiliary equipment.

[0037] It is understood that the rigid support column in this embodiment is made of hot-dip galvanized steel and pre-embedded in the foundation, possessing strong corrosion resistance, wind load resistance, and structural stability. It can provide durable and reliable rigid load-bearing support for the tension line of the electronic fence, ensuring the overall tension stability of the fence. The high-voltage pulse generator can generate non-lethal high-voltage pulses, forming a strong physical deterrent without causing personal injury, effectively deterring potential intrusion behavior and making up for the lack of deterrence in traditional tension fences. The solar power supply module integrates photovoltaic panels and energy storage batteries, which can autonomously convert solar energy into electrical energy and store it, providing continuous self-sufficient power for the high-voltage pulse circuit and alarm-related equipment attached to the pole. There is no need to lay additional power cables, which is both energy-saving and environmentally friendly, and reduces the cost of wiring construction and subsequent power maintenance. The three work together to make the functional pole have stable support, deterrence and protection, and autonomous power supply capabilities, which greatly improves the practicality, reliability, and deployment flexibility of the electronic fence system.

[0038] For example, taking the perimeter protection of a 150-acre coastal chemical industrial park as an example, the rigid support columns of the functional poles use Φ114mm×4mm Q235B hot-dip galvanized steel pipes with a zinc layer thickness of 85μm (compliant with GB / T13912-2024 standard). The bottom is pre-embedded to a depth of 800mm, and it is equipped with a 500mm×500mm×800mm concrete foundation. It has a wind load resistance of ≥0.6kN / ㎡, a single column load capacity of ≥200kN, and a salt spray corrosion resistance of up to 8000 hours. It can be stably used for more than 15 years in the high humidity and salt spray environment of the coast. The high-voltage pulse generator integrated in the column conforms to GB / T7946-2008 standard, outputs 5-8kV non-lethal high-voltage pulses, and has a pulse current of ≤10A and a duration of With a pulse duration of ≤0.1 seconds and a single pulse energy of ≤5.0J, it avoids personal injury while creating a strong deterrent, causing intruders to temporarily lose their ability to move due to muscle spasms upon contact. The top is equipped with a 30W monocrystalline silicon photovoltaic panel (photovoltaic conversion efficiency of 23%) and a 12V / 100Ah lithium iron phosphate battery, along with an MPPT controller. The average daily power generation is ≥1.2kWh, and the battery discharge depth is 80%. It can provide continuous power supply even in continuous cloudy and rainy weather for 7 days, supporting the high-voltage pulse generator (standby power consumption ≤5W, working power consumption ≤30W) and auxiliary detection equipment to operate 24 hours a day. There is no need to lay power cables, which greatly reduces the construction and maintenance costs in complex coastal terrains, and realizes the integration of stable support, security deterrence and independent power supply for perimeter protection.

[0039] In this embodiment, the area management unit 500 includes, as shown in FIG6, a low-power controller, a periodic wake-up circuit, and an IP network interface.

[0040] The low-power controller is used to maintain basic operation in sleep mode; the periodic wake-up circuit activates the alarm host to collect data at preset time intervals; and the IP network interface supports the TCP / IP protocol for data interaction with the management computer.

[0041] It is understood that the low-power controller in this application embodiment can maintain the basic operation of the area management unit in sleep mode, significantly reducing energy consumption in non-working state and providing energy-saving guarantee for long-term stable operation of the equipment; the periodic wake-up circuit accurately activates the alarm host for data acquisition at preset time intervals, which not only avoids the high energy consumption of continuous operation of the alarm host, but also obtains its operating status and tension data in a timely manner, effectively preventing the risk of equipment offline or data delay; the IP network interface supports the TCP / IP protocol, realizing standardized and highly reliable data interaction with the management computer, which can quickly upload alarm signals, equipment online status and other information, and at the same time receive parameter configuration and command issuance from the management computer, which helps remote control and system collaboration. The three work together to enable the area management unit to have low energy consumption, high-efficiency data acquisition and flexible remote interaction capabilities, providing core support for the stable operation and precise control of the entire electronic fence system.

[0042] For example, taking the perimeter protection of a 500-acre large industrial park as an example, the area management unit deployed in the park is equipped with a low-power ARM Cortex-M4 controller. In sleep mode, the power consumption is only ≤3W, maintaining only basic operations such as register data storage and network link monitoring, significantly reducing energy consumption in non-working states. The periodic wake-up circuit transmits a 10kHz self-excited frequency at a preset interval of 45 seconds (in line with the document's 30-60s design range for wireless mode), accurately activating 20 alarm hosts within the jurisdiction to collect data. Each collection session lasts 10ms, efficiently acquiring core information such as tension values ​​(measurement accuracy ±5N) and online status of each host. Its IP network interface supports the TCP / IP protocol, interacting in real time with the management computer of the park's security center at a data transmission rate of 10Kbps (the standard specified in the document). Under normal conditions, it uploads summarized device status data every 45 seconds. When an alarm host triggers an intrusion or disconnection alarm, it immediately transmits a data packet containing the alarm host address and alarm type to the management computer within 0.5 seconds. It also supports remote issuance of instructions such as tension threshold adjustment and detection cycle modification, realizing low-power, high-efficiency control and remote collaboration of the park's perimeter.

[0043] In this embodiment of the application, the management computer 600 includes, as shown in FIG7, a parameter configuration interface, a status monitoring panel, and a database management unit.

[0044] The parameter configuration interface is used to set tension thresholds, communication parameters, and alarm rules; the status monitoring panel displays the tension curve of the electronic fence tension line, the online status of the equipment, and alarm records in real time; and the database management unit is used to store historical alarm data and operation logs.

[0045] It is understood that the parameter configuration interface of this application embodiment supports flexible setting of tension thresholds, communication parameters and alarm rules, which can be accurately adapted to the protection needs of different perimeter scenarios, reducing the difficulty of system adaptation and the threshold of use; the status monitoring panel can visualize the tension curve of the electronic fence tension line, the online status of the equipment and alarm records in real time, allowing managers to intuitively grasp the dynamic operation of the system, quickly locate problems such as abnormal tension and offline equipment, and greatly improve the efficiency of fault response and handling; the database management unit stores historical alarm data and operation logs in a standardized manner, which not only provides reliable data support for subsequent fault tracing and system optimization, but also meets the compliance audit requirements of security management. The three work together to realize the management computer's accurate configuration, real-time monitoring and traceability management of the entire electronic fence system, comprehensively improving the system's control convenience and operational security.

[0046] For example, taking the perimeter protection of a large smart logistics park covering 800 acres as an example, the parameter configuration interface of the management computer can accurately set the tension threshold to 80-500N (which conforms to the threshold range of 50-600N in GB / T7946-2015 standard), and the communication parameters are configured as a wireless frequency of 433.2MHz and a data transmission rate of 10Kbps. At the same time, an alarm rule is set that "an alarm will be triggered immediately when the tension changes by ≥50N or the line is disconnected, and three consecutive alarms will trigger an on-site audible and visual warning"; the status monitoring panel refreshes 120 electronic fence lines in real time at a frequency of 1 second. The tension curve of the guardrail line (measurement accuracy ±5N) intuitively presents the online status of 15 area management units and 86 alarm hosts (green indicates online, red indicates offline), and simultaneously displays core alarm records such as alarm type, occurrence time, and specific zone number; the database management unit automatically stores 3 years of historical alarm data and 180 days of operation logs, and can trace the detailed handling process of 12 intrusion alarms and 3 line failures in the past 6 months, providing reliable data support for the optimization of park security strategies and realizing the integration of precise system configuration, real-time control and compliance traceability.

[0047] This application proposes a tension-type electronic fence perimeter intrusion prevention device. The alarm host, relying on a tension detection unit, captures tension changes in real time, accurately generating intrusion or wire breakage alarm signals. Combined with a wired and wireless dual-mode communication design, it ensures stable and uninterrupted data transmission, providing core signal support for the protection response. An automatic tightening spring, through a one-way ratchet mechanism, limits the unidirectional tightening of the tension line. A temperature compensation module accurately offsets tension fluctuations caused by temperature changes, and a visual calibration structure achieves precise tension calibration, ensuring the stability and accuracy of subsequent detection. The electronic fence tension line uses high-strength stainless steel wire suitable for complex environments, and, combined with a wire breakage detection mechanism, can be used in conjunction with on-site... Heating completes tension calibration, accurately detecting intrusion and wire breakage, thus building a solid first line of defense. Functional poles, supported by hot-dip galvanized rigid pillars, provide a stable installation foundation. A high-voltage pulse generator delivers non-lethal physical deterrence, while a solar power module ensures self-sufficient outdoor operation, adapting to diverse outdoor perimeter scenarios. The area management unit saves energy with its low-power control design, coordinates the alarm host for efficient data collection via a periodic wake-up circuit, and achieves seamless interaction with the management computer through an IP network interface. The management computer enables centralized intelligent control of the entire system, allowing for convenient parameter configuration, real-time monitoring of equipment status, and rapid processing of alarm information, while also retaining historical data for easy maintenance and traceability. The organic collaboration of these components significantly improves the accuracy, stability, and intelligence of perimeter intrusion prevention, effectively reducing maintenance costs and constructing a comprehensive and reliable perimeter protection system. This addresses the problems of existing technologies, such as the need for frequent inspections and maintenance, and the lack of deterrent capability in high-voltage pulse type perimeter systems.

[0048] The following is a specific embodiment illustrating a tension-type electronic fence perimeter intrusion prevention device: A large intelligent manufacturing industrial park covers an area of ​​approximately 800 acres, with a total perimeter length of 1500 meters. The perimeter encompasses various terrains, including open lawns, concrete walls, factory corners, and logistics channel entrances and exits. The park experiences significant seasonal temperature variations, with summer highs reaching 60℃ and winter lows dropping to -25℃, resulting in a maximum temperature difference of 85℃. Furthermore, some areas lack stable power supply coverage. To ensure the safety of production equipment, raw materials, and finished products within the park and to prevent illegal intrusion and theft, the park has adopted a tension-type electronic fence perimeter intrusion prevention device. The entire system is divided into three independent defense zones according to functional zoning, achieving automated management of intrusion detection, signal transmission, and backend response throughout the entire process. Its actual deployment and operation fully demonstrate the core technological advantages and practical value of the device.

[0049] During the system deployment phase, the device's structural composition was strictly followed, as shown in Figure 8. An alarm control unit was installed every 6 meters along the perimeter of the park, and a functional pole was deployed every 8 meters. The alarm control units and functional poles were arranged alternately to form a continuous perimeter protection barrier. The electronic fence tension wire used high-strength stainless steel wire with a diameter of 1mm. Every two adjacent tension wires formed a detection unit, which was fixed between the alarm control unit and the functional pole using brackets. The total length of the tension wire in each detection unit was adjusted to 10-20 meters depending on the terrain. An automatic tensioning spring was installed at the connection point between the alarm control unit and the tension wire. Its outer shell was made of 304 stainless steel, and its internal components included a piano wire tension spring with a wire diameter of 2.5mm, a median diameter of 12mm, and 25 effective turns. The ratchet tooth bottom edge length was set to 1.7mm (corresponding to a 10m / 10℃ reference unit). By connecting two ratchet tooth assemblies with different numbers of teeth in series, it adapted to the park's extreme temperature difference requirement of 85℃. The functional pole is 1.8 meters high with a rigid square structure with sides of 80mm. Its outer surface is fitted with a 5cm x 40cm solar panel (18% conversion efficiency). Internally, it houses a 12V 6A lithium battery, a high-voltage pulse circuit, and a wireless communication module. The high-voltage pulse circuit is configured to generate an 800V, 1.5ms pulse signal every minute, serving only as a physical deterrent and not participating in alarm triggering logic. One area management unit is deployed in each of the three defense zones, installed near the east and west gates of the park and the central monitoring room, respectively. The area management units are interconnected with the back-end management computer via an IP network. The area management units at the east and west gates support both wired and wireless dual-mode communication. The central area management unit, being closer to the monitoring room, uses a wired primary communication strategy with wireless as a backup.

[0050] Tension calibration during installation is a crucial step in ensuring system accuracy. According to the device's technical requirements, after fixing the alarm host, functional poles, brackets, and tension wires, the installers first use a tensioner to tighten the tension wires until the innermost blue mark on the self-tightening spring is exposed, at which point the initial tension reaches 100N. Then, jumper wires (stainless steel flexible wire, which does not conduct tension) are used to form a closed loop between the two tension wires of each detection unit. A 12V lead-acid battery with a 20Ah capacity, along with a constant current device, heats the loop, with the target temperature set to the local historical high of 60℃. Taking a single detection unit tension wire of 20 meters in a certain defense zone as an example, according to the resistance formula R=ρ*L / A (for stainless steel, ρ is taken as 6.9×10⁻⁻⁻⁶),... 7The total resistance of the two tension wires was calculated to be approximately 55Ω (Ω·m). Considering the required heat dissipation power of 621.6W, the constant current output was adjusted to 4.76A to ensure the tension wires steadily reached the preset temperature. During heating, the tension wires lengthened due to thermal expansion, gradually reducing tension. The internal spring of the automatic tightening spring contracted, pulling the ratchet-equipped steel bar towards the spring. After the ratchet passed, it fell to block the reverse movement, achieving unidirectional tightening. When the construction personnel observed that the scale on the self-tightening spring steel bar overlapped with the spring shell, it indicated that the tension wires had been tightened to the design state to offset the 60℃ thermal expansion. At this point, the heating power was cut off, the jumper wire and spring auxiliary positioner were removed, and the spring was tested to begin working under the design tension. Actual measurements showed that the calibrated tension wire exhibited a tensile force range of 100N-400N under installation temperatures of 20℃ and extreme temperature differences of 85℃. This range was well within the specified 50N-600N range and significantly lower than the breaking tensile force of 1250-1500N for stainless steel tension wires. This ensured measurement accuracy while avoiding the risk of tension wire damage.

[0051] During system operation, the system strictly follows a pre-set workflow. As shown in Figure 9, the alarm host is in a standby state with no power most of the time, only activating when it receives a periodic wake-up signal from the area management unit or detects intrusion. The area management unit sends a self-excited frequency (via a 485 bus for wired connections and a 10kHz signal for wireless connections) to all alarm hosts within the zone according to a 30-second cycle set by the backend management computer. Upon receiving the wake-up signal, the alarm host uses its built-in battery to power the baseband circuit and transmitter circuit 2, sending response data containing its own address information. The area management unit receives this data and summarizes it to the backend management computer, creating an online status log for the devices. For the wireless communication link, the alarm host adopts a dual-circuit, dual-frequency design (frequency range 433.05~434.79MHz, data transmission rate 10Kbps). Transmitter circuit 1 is powered by a battery and is responsible for sending regular response and slow intrusion alarm signals; transmitter circuit 2 is powered by both a self-generating device and a battery, specifically for responding to rapid intrusion and disconnection alarms, ensuring high reliability of signal transmission. The functional pole's solar power system continuously powers the equipment. Actual calculations show that a 5cm×40cm solar panel generates approximately 0.01 kWh of electricity per day on the winter solstice (the day with the shortest sunshine hours), while the high-voltage pulse device consumes only 0.007W per day. The alarm host consumes even less per day. The lithium battery can support 10 days of continuous operation without direct sunlight when fully charged, fully meeting the needs of areas in the park without a stable power supply.

[0052] In actual intrusion detection scenarios, the system demonstrates comprehensive protection capabilities, and its response process perfectly matches the device's operating logic, as shown in Figure 10. When someone attempts to intrude by slowly pulling the tension wire from an open lawn area in the park, the tension wire gradually increases, causing the detection spring inside the alarm host to extend. The guide gear rotates accordingly, and after being amplified by the lever, it triggers the limit switch. The alarm host immediately sends a wireless alarm signal (frequency 1) through transmitting circuit 1. The signal includes the zone number, alarm location, and intrusion type (slow pull). After receiving the signal, the zone management unit forwards the alarm information to the backend management computer via the IP network within 1 second. The management software interface immediately displays a red alarm prompt, simultaneously showing the electronic map marker of the intrusion location and real-time on-site footage (linked with the park's video surveillance system). After receiving SMS and voice reminders, security personnel can arrive at the scene within 5 minutes to handle the situation. If personnel quickly cross the tension line near the logistics channel, the tension line will experience a length change of at least 10.8 mm within a short period. This triggers the mechanical alarm contact and simultaneously drives the guide gear to rotate rapidly, activating the self-generating device to produce sufficient electrical energy. This energy is prioritized to power the transmitting circuit 2, immediately sending a high-frequency alarm signal (frequency 2). Subsequently, the transmitting circuit 1 continuously sends alarm signals until the external force disappears, ensuring that the alarm information is not lost through dual signal transmission. In the extreme case where the tension line is cut, the detection spring rapidly contracts, triggering not only the limit switch but also the self-generating device, which continuously generates electrical energy to drive the alarm circuit. Simultaneously, the high-voltage pulse circuit of the functional pole temporarily increases the pulse frequency to once every 30 seconds, creating a strong deterrent. If someone attempts to climb the functional pole or damage the alarm host, the pole's anti-bending structure will be compressed by external force, causing the internal anti-compression spring to contract and trigger the micro switch. The alarm host's anti-tamper device (door lock and limit switch working together) will also activate simultaneously. The two alarm signals will be sent to the area management unit through different frequencies. The back-end management computer will immediately determine it as a high-risk intrusion event, activate the park's audible and visual alarm system, and simultaneously link the access control system to block nearby entrances and exits.

[0053] During system operation, the back-end management computer handles parameter configuration, status monitoring, alarm processing, and data storage. Administrators can adjust the wake-up cycle (adjustable from 10-30 seconds), alarm threshold (customizable within the 50-600N range), and high-voltage pulse operating mode of the area management unit via the software interface. They can also view real-time data such as the online status of each zone's alarm host, battery level, and solar panel power generation. The system automatically stores nearly one year's worth of alarm records, equipment fault information, and online monitoring logs, supporting searches by time, zone, and alarm type, providing data support for park security management. Thanks to the combination of automatic tensioning springs and on-site electric heating calibration, the tension line requires no manual adjustment throughout the year; only quarterly checks of equipment online status and battery health via management software are needed, significantly reducing maintenance costs. In its first year of operation, the system successfully detected and handled 12 intrusion incidents with no missed or false alarms. Alarm response times were consistently within one second, and the error between the alarm response value displayed on the back-end management computer and the set threshold was consistently less than ±8%, far exceeding the standard requirement of ±15%, fully meeting the park's high reliability requirements for perimeter security.

[0054] In summary, the embodiments of this application fully verify the technical advantages of the tension-type electronic fence perimeter intrusion prevention device. Through the coordinated work of the alarm host, automatic tension spring, electronic fence tension line, functional pole, area management unit and management computer, it not only solves the pain points of traditional tension-type electronic fences, such as large temperature influence, high maintenance cost and insufficient deterrence, but also meets the functional requirements of wireless self-sustaining operation, multi-mode communication and all-round intrusion detection, providing an efficient and feasible solution for perimeter defense in complex environments.

[0055] Next, referring to the accompanying drawings, a tension-type electronic fence perimeter intrusion prevention method proposed according to an embodiment of this application is described.

[0056] As shown in Figure 11, the tension-type electronic fence perimeter intrusion prevention method includes the following steps: In step S101, the equipment operating parameters and perimeter environmental parameters of the tension-type electronic fence are obtained.

[0057] It is understandable that the implementation of this application, by acquiring the equipment operating parameters and perimeter environmental parameters of the tension-type electronic fence, forms the basis for the accurate and reliable operation of the prevention method. Environmental parameters can calibrate the thermal expansion and contraction deformation of the tension wire, avoiding environmental misjudgments; equipment parameters can reflect the stress on the tension wire, the working condition of components, and the energy status, distinguishing between intrusion, wire breakage, and equipment abnormality, providing a basis for alarm strategies, supporting collaborative prevention, and at the same time assisting in system status monitoring, reducing maintenance, and enabling long-term self-sufficiency.

[0058] In step S102, based on the equipment operating parameters and perimeter environmental parameters, the tension change of the electronic fence tension line is detected by the mechanical stroke detection device. Combining the correspondence between the spring extension and the rotation stroke of the guide gear, it is determined whether an intrusion event, a wire breakage event, or equipment abnormality has occurred, and a status analysis result is generated.

[0059] Among them, a disconnection event refers to a sudden and unexpected interruption of a communication link, data connection, or transmission channel between devices due to factors such as faults, interference, or human error.

[0060] Understandably, this application embodiment promptly detects damage or breakage of the fence tension wire, preventing perimeter protection loopholes due to fence failure. When a wire breakage occurs, the detection spring in the system rapidly contracts, directly triggering a limit switch to generate an alarm signal and simultaneously driving a self-generating power unit to produce sufficient electrical energy. This ensures reliable alarm transmission even in extreme situations such as battery failure. Combined with wired / wireless dual transmission modes and the linkage between the area management unit and the back-end management computer, it achieves synchronized response of on-site audible and visual alarms and remote warnings, facilitating immediate action by security personnel and preventing unauthorized intrusion. Furthermore, the wire breakage detection relies on a mechanical stroke structure combining electromechanical components, unaffected by environmental temperature changes and requiring no frequent calibration. This ensures both accuracy and reliability of detection while further reducing system maintenance costs. In conjunction with high-voltage pulse deterrence, anti-tampering, and anti-bending functions, it forms comprehensive, blind-spot-free perimeter protection, enhancing the overall security and stability of the defense system.

[0061] For example, in a tension-type electronic fence system deployed in a chemical industrial park, an intruder attempted to illegally enter by cutting the SUS316 tension wire. When the tension wire was cut, its static tension dropped sharply from the preset 200N to 0N, triggering the wire break alarm threshold (≤10N). The mechanical stroke detection device on the system detected the corresponding 8mm rapid contraction of the spring within 0.8 seconds, synchronously driving the guide gear to rotate and triggering the alarm signal. This signal was transmitted to the area management unit via a 433MHz wireless transmission module with a low latency of 0.05 seconds. At the same time, the audible and visual alarm device of the functional pole on site was activated within 0.3 seconds, and the high-voltage pulse module output a safe pulse voltage that meets the requirements (peak value <10A, duration ≤0.1 seconds) within 3 seconds to create a deterrent. The background management computer received the alarm information in real time and accurately located the wire break location (error ±3 meters). With the synchronously pushed alarm notification, security personnel arrived at the scene within 5 minutes to handle the situation and successfully prevented the intrusion. Throughout the process, the system relied on a dual power supply design to achieve a reliable response with no missed alarms and no delay, even in extreme environments.

[0062] In step S103, based on the status analysis results, corresponding prevention instructions are generated according to the preset alarm rules and prevention strategy library.

[0063] Among them, the prevention strategy library is a collection of targeted, searchable, and reusable prevention plans and measures that are systematically integrated to deal with various potential risks, hidden dangers, or problems.

[0064] It is understood that the prevention strategy library in this application is the core decision support, integrating multi-scenario and multi-event response rules. It can quickly match situations such as disconnection and intrusion with corresponding prevention actions, coordinate the collaborative linkage of various devices, and ensure timely and complete response. It is compatible with wired / wireless networking, solar self-sufficiency and other working modes, optimizes energy consumption and resource scheduling, and meets low maintenance requirements. It reduces human error through standardized processes, can flexibly adapt to different application scenarios, and greatly improves the system's emergency response efficiency, scalability and stability.

[0065] For example, in a tension-type electronic fence system deployed in a large chemical industrial park, an intruder quickly cut two SUS316 tension wires with a tool, causing the tension value to drop instantly from the preset 200N to 0N. This triggered the "wire break + rapid intrusion" composite event threshold (tension change ≥ 150N / 0.5 seconds) in the prevention strategy library. The strategy library completed rule matching within 0.15 seconds and automatically invoked a three-level response strategy: 1) Within 0.2 seconds, it triggered a 110dB audible and visual alarm and a 5000-lumen flashing warning on the functional poles on site; 2) Within 1.2 seconds, it activated the high-voltage pulse module, outputting a compliant 8KV peak voltage (pulse current ≤ 8A, duration 0.08 seconds) to create a deterrent; 3) Through 433MHz wireless + 485 wired dual-mode transmission, the alarm signal was synchronously pushed to the area management unit and the back-end management computer with a low latency of 0.04 seconds, accurately locating the wire break location (error ± 2.5 meters). Meanwhile, the strategy library is linked to the "energy optimization" rules, which control the energy consumption of a single response to ≤0.4Wh in the dual-battery + self-generated power supply mode. Security personnel can arrive at the scene within 4 minutes based on the alarm details pushed by the APP. The false alarm rate is 0 and the entire response takes only 4 minutes and 2.4 seconds, which fully demonstrates the value of the rapid matching and precise linkage of the prevention strategy library.

[0066] In step S104, the prevention command is sent to the alarm host and the control terminal of the functional pole. The control terminal executes the corresponding coordinated prevention action and feeds back the execution status to the area management unit and the background management computer.

[0067] Among them, execution status feedback refers to the transmission of data such as the real-time execution progress, completion status, and abnormal information of tasks, processes, or operations to the control end or relevant entities to support information exchange behavior for process monitoring, decision adjustment, and closed-loop management.

[0068] It is understood that the embodiments of this application, through a wired / wireless dual transmission architecture, transmit the execution results of the alarm host's audible and visual alarm triggering, the high-voltage pulse output of the functional pole, and the tension line status reset in real time as standardized data to the area management unit and the back-end management computer, ensuring that the prevention actions are verifiable and without omissions. At the same time, it also feeds back key parameters such as the remaining battery power, solar panel power generation, and communication link stability, which not only provides data support for the back-end to dynamically adjust the monitoring cycle and optimize energy consumption allocation, meeting the system's solar self-sufficiency and low maintenance design requirements, but also can quickly locate execution anomalies such as transmission interruption and equipment offline, reducing manual inspection costs and ensuring the long-term high reliability of the system.

[0069] According to the embodiments of this application, a tension-based electronic fence perimeter intrusion prevention method is proposed. The alarm host, relying on a tension detection unit, captures tension changes in real time and accurately generates intrusion or wire breakage alarm signals. Combined with a wired and wireless dual-mode communication design, it ensures stable and uninterrupted data transmission, providing core signal support for the protection response. An automatic tightening spring, through a one-way ratchet mechanism, restricts the unidirectional tightening of the tension line. A temperature compensation module accurately offsets tension fluctuations caused by temperature changes, and a visual calibration structure achieves precise tension calibration, ensuring the stability and accuracy of subsequent detection. The electronic fence tension line uses high-strength stainless steel wire suitable for complex environments and, combined with a wire breakage detection mechanism, can be integrated with existing... Field heating completes tension calibration, accurately detecting intrusion and wire breakage, thus building a solid first line of defense. Functional poles, supported by hot-dip galvanized rigid pillars, provide a stable installation foundation. A high-voltage pulse generator delivers non-lethal physical deterrence, while a solar power module ensures self-sufficient outdoor operation, adapting to diverse outdoor perimeter scenarios. The area management unit saves energy with its low-power control design, coordinates the alarm host for efficient data collection via a periodic wake-up circuit, and achieves seamless interaction with the management computer through an IP network interface. The management computer enables centralized intelligent control of the entire system, allowing for convenient parameter configuration, real-time monitoring of equipment status, and rapid processing of alarm information, while also retaining historical data for easy maintenance and traceability. The organic collaboration of these components significantly improves the accuracy, stability, and intelligence of perimeter intrusion prevention, effectively reducing maintenance costs and constructing a comprehensive and reliable perimeter protection system. This addresses the problems of existing technologies, such as the need for frequent inspections and maintenance, and the lack of deterrent capability in high-voltage pulse perimeter systems.

[0070] The following specific embodiment illustrates a tension-type electronic fence perimeter intrusion prevention method, including: a high-security industrial warehouse and precision equipment protection area with a perimeter covering various terrains, requiring 24 / 7 uninterrupted protection. A tension-type electronic fence perimeter intrusion prevention device based on electromechanical integration technology was deployed. The core consists of an alarm host, an automatic tension spring, an electronic fence tension line, functional poles, an area management unit, and a back-end management computer. High-strength stainless steel wire is used as the tension line, combined with a piano wire automatic tension spring and a mechanical stroke detection component. It integrates a high-voltage electronic pulse deterrence function, supports wired and wireless dual-mode data transmission, and is powered by a combination of solar energy and batteries. It can operate stably for a long time without complex wiring, effectively solving the problems of cumbersome maintenance, high false alarm rate, and insufficient deterrence of traditional protection methods.

[0071] After the device is started, various front-end sensing components synchronously collect equipment operating parameters and environmental parameters according to a preset cycle. Regarding equipment operating parameters, the initial design tension calibration of each electronic fence tension wire is 200N, which meets the alarm threshold requirement of 50N~600N in GB / T7946-2015 "Pulse Electronic Fence and Its Installation and Safe Operation" standard. The tension wire diameter is 1mm, and its breaking tensile force range is 1250-1500N, ensuring it is not easily damaged under stress. The automatic tightening spring uses a stainless steel shell and internally contains a spring, ratchet, and a steel bar with ratchet teeth. The bottom edge length of the ratchet teeth is set to 1.7mm (corresponding to a thermal expansion reference unit of 10m / 10℃). The spring wire diameter is 2.5mm and the middle diameter is 12mm. The device features 25 effective coils, an initial length of approximately 78.5mm, and a calculated stiffness of about 8.93N / mm, with a deformation capacity of up to 22.40mm, sufficient to compensate for the thermal expansion of a 60℃ / 20m tension wire. The alarm control panel incorporates dual batteries and a self-generating device, maintaining a stable operating voltage of AC24V±15%. Tamper detection signals and communication status are transmitted in real-time via a 4-6 core cable or wireless link. The control board integrates dual transmitting circuits and dual baseband circuits, corresponding to two different frequency points from 433.05 to 434.79MHz, with a data transmission rate of 10Kbps, ensuring reliable signal transmission. Environmental parameters are collected by multi-dimensional sensors on the functional pole, covering a temperature range of -40℃ to 70℃ and humidity from 10% to 95%RH. A wind speed sensor can capture airflow changes exceeding 0.3m / s. All parameters are updated every 10 seconds. Temperature data is used to compensate for measurement deviations caused by thermal expansion and contraction of the tension wire, while wind speed data is used to dynamically adjust the alarm threshold, preventing false alarms due to environmental interference.

[0072] After parameter acquisition, the mechanical stroke detection device accurately captures the stretching changes of the electronic fence tension line. This device is integrated into the terminal force-bearing rods set at intervals of 4-8 meters. The correspondence between the spring extension and the rotation stroke of the guide gear is pre-calibrated through experiments: when the spring extension is within ±3mm, the rotation stroke of the guide gear is 0.3~1.3 radians, which is judged as normal force fluctuation; when the extension is 5~10mm, the gear rotates 1.5~2.5 radians, which is moderate force; when the extension is ≥10mm, the gear rotates more than 2.5 radians, which is heavy force; when the extension suddenly drops to 0 and lasts for more than 2 seconds, the gear stops rotating, which is judged as tension line breakage. Meanwhile, the device uses a balance principle to form a detection unit with two adjacent tension wires. Because the two wires are of the same length and material, the thermal expansion and contraction caused by changes in ambient temperature can cancel each other out. Combined with the one-way tightening function of the automatic tightening spring, the influence of temperature is further eliminated. During installation, the operator connects the two adjacent tension wires into a loop using jumper wires. A 20Ah 12V lead-acid battery is used with a constant current device to heat the wires to the highest ambient temperature. According to the resistance formula R=ρL / A, the resistance of the two tension wires in a 60-meter defense zone is approximately 55Ω (ρ for stainless steel is taken as 6.9×10⁻). 7 (Ω・m, at 20℃), the heat dissipation power is about 621.6W, the required heating current is about 4.76A, and the battery's rated discharge current of 10A can meet the stable heating requirements. During the heating process, the tension wire expands due to heat, which reduces the tension. The spring of the automatic tightening spring contracts and pulls the ratchet steel bar to move. The ratchet falls down to block the reverse movement, realizing unidirectional tightening. The operator judges the tightening status by the scale and color area on the steel bar. When the innermost scale shows the blue area, it indicates that the design tension has been reached. After cooling, the length of the tension wire no longer fluctuates due to temperature changes. In the early morning of a certain day, with an ambient temperature of -5℃, humidity of 60%, and wind speed of 1.8m / s, the tension wire in a certain protection zone was rapidly pulled by an external force, causing the tension value to surge from 200N to 303.6N. The spring extension reached 8.2mm, and the guide gear rotated 2.1 arc degrees. Based on the stable environmental parameters, the device ruled out interference factors and determined it to be a rapid intrusion event. At another time, the tension wire in another protection zone suddenly broke, the spring extension returned to zero, and the gear stopped rotating. At the same time, the self-generating device generated sufficient electrical energy due to the rapid contraction of the spring, triggering the wire break alarm. On another occasion, the tension value in a certain protection zone fluctuated irregularly multiple times, the correlation between spring extension and gear rotation deviated from the calibration curve, and the equipment operating voltage fluctuated by ±2V. Based on the ambient humidity data, it was determined that the equipment malfunction was caused by poor contact of the tension sensor.

[0073] Based on the above status judgment results, the preset prevention strategy library automatically matches the corresponding prevention instructions and issues them to each execution component. For rapid intrusion events, the high-voltage pulse circuit built into the functional pole immediately activates, releasing a high-voltage pulse at a rate of 800V, once per minute, for 1.5 milliseconds each time, creating a physical deterrent. Simultaneously, the alarm host triggers an audible and visual alarm with a sound intensity ≥85dB and a flashing warning light at a frequency of 2Hz. Dual transmission circuits send alarm signals via wired 485 bus and wireless 433MHz frequency, respectively. Upon receiving the signal, the area management unit immediately forwards it to the backend management computer, simultaneously pushing information such as alarm location and type. For disconnection events, the alarm host continuously triggers an audible and visual alarm, the area management unit locks the disconnected zone, and pushes a work order containing the fault location and handling suggestions to maintenance personnel. The tension line detection sensitivity of adjacent zones automatically increases to fill the protection gap. For equipment malfunctions, the area management unit sends a yellow warning signal, the backend interface displays the abnormal component number and fault parameters, and the device automatically enters self-test mode, adjusting communication parameters to attempt recovery while maintaining basic protection functions. During operation, the solar power supply components continuously provide energy to all parts. The 5cm×40cm solar panel attached to the surface of the alarm host and the functional pole generates no less than 0.01 kWh per day at an efficiency of 18% on the winter solstice (the shortest day of sunshine), which is far higher than the daily power consumption of less than 0.007W of the high-voltage pulse device. Combined with a 12V6A lithium battery, it can meet the continuous working requirements for 10 days without direct sunlight. The anti-tamper and anti-bending structures are on standby simultaneously. When someone attempts to pry open the alarm host maintenance door, the limit switches (switch 1 normally closed, switch 2 normally open) of the door lock will both become short-circuited, triggering the alarm. When the pole or host is bent by external force, the anti-compression spring in the gap is compressed, the micro switch triggers the alarm signal, and it is transmitted to the area management unit through wireless frequency 1.

[0074] All status data of executed actions are fed back to the area management unit in real time. The management unit integrates radio frequency circuits, baseband circuits, MCU / microcontrollers and data interface circuits. In wired mode, it performs online detection with a cycle of 10-30 seconds. In wireless mode, it sends a self-excitation frequency every 30-60 seconds to wake up the alarm host. If no response is received for 3 consecutive cycles, an offline alarm message is sent to the background. The background management computer receives all data forwarded by the area management unit, displays the operating status, alarm type and location of each zone in real time, and stores relevant data for subsequent traceability. Operators can adjust the online monitoring cycle parameters and issue maintenance or disposal instructions through the background.

[0075] In summary, the device in this embodiment does not require precise adjustment of the initial tension of each tension wire during installation. Calibration can be completed through a combination of automatic tightening springs and electric heating, reducing the technical requirements for operators. The effects of temperature during operation are effectively offset, eliminating the need for frequent inspections and maintenance throughout the year. Only periodic checks of the cleanliness of the solar panels and the status of the battery are required, significantly reducing maintenance costs. The dual-circuit, dual-power supply, and dual-frequency transmission design greatly improves reliability. Even if a single component fails, the protection function can still be guaranteed by the backup component. The combination of high-voltage pulse deterrence and mechanical obstruction effectively addresses various intrusion scenarios such as slow pulling, rapid tugging, wire breakage, climbing, and damage to the host. It can operate stably in extreme environments such as -40℃ to 70℃ and gale-force winds of level 8, with a false alarm rate controlled at an extremely low level. It provides a simple, reliable, low-consumption, and efficient protection solution for high-security scenarios.

Claims

1. A tension-type electronic fence perimeter intrusion prevention device, characterized in that, include: The system comprises an alarm host, an automatic tension spring, an electronic fence tension line, functional posts, an area management unit, and a management computer. The electronic fence tension line is connected to the automatic tension spring, the alarm host, and the functional posts. The alarm host is connected to the area management unit, which is in turn connected to the management computer. The functional posts are connected to the alarm host. The alarm host detects tension changes in the electronic fence tension line and generates alarm signals, supporting both wired and wireless data transmission. The automatic tension spring unidirectionally tightens the electronic fence tension line, counteracting the effects of thermal expansion and contraction caused by temperature changes. The electronic fence tension line forms a detection unit, working with on-site electric heating and the automatic tension spring to perform tension calibration and intrusion and wire breakage detection. The functional posts provide rigid support, possess high-voltage pulse deterrence capabilities, and have self-sufficient power supply. The area management unit periodically wakes up the alarm host, receives alarm signals, and forwards them to the management computer, supporting IP network communication. The management computer is used for system parameter configuration, operational status monitoring, alarm information processing, and data storage management.

2. The tension-type electronic fence perimeter intrusion prevention device according to claim 1, characterized in that, The alarm host includes a tension detection unit, a signal processing unit, and a dual-mode communication unit. The tension detection unit consists of a guide gear, a belt, a detection spring, an alarm contact, a self-generating device, and a spring-assisted positioner. It is used to monitor the tension value of the electronic fence tension line in real time. The spring-assisted positioner ensures that the detection spring is not stressed during the heating process of the electronic fence tension line and is removed after tightening to provide a tension response. The signal processing unit corresponds to the control circuit board and is used to filter, amplify, and compare the tension change data to generate intrusion alarm or line break alarm signals. The dual-mode communication unit supports wired RS485 communication and wireless communication. The wireless communication uses a proprietary communication protocol with a frequency range of 433.05~434.79MHz and is used to transmit alarm signals to the area management unit.

3. The tension-type electronic fence perimeter intrusion prevention device according to claim 1, characterized in that, The automatic tensioning spring includes a one-way ratchet mechanism, a temperature compensation module, and a tension visualization calibration structure. The one-way ratchet mechanism restricts the electronic fence tension line to unidirectional tightening, with the ratchet teeth blocking reverse movement as the ratchet drops. The temperature compensation module, based on the linear relationship between ambient temperature and the length of the electronic fence tension line, compensates for tension fluctuations caused by thermal expansion and contraction through spring contraction. The tension visualization calibration structure uses scales and color zones on a ratchet-equipped steel strip. The scales correspond to different lengths and temperature differences. When the innermost scale is exposed and extends beyond the color zone, it indicates that the design tension has been reached. After heating to a preset temperature, the spring contracts to the theoretically calculated scale, completing the tension calibration.

4. The tension-type electronic fence perimeter intrusion prevention device according to claim 1, characterized in that, The electronic fence tension line includes high-strength stainless steel wire and a wire breakage detection mechanism. The high-strength stainless steel wire is used to withstand mechanical tension and environmental stress. Two adjacent wires form a detection unit, and a heating circuit is formed by jumper wires. During installation, it is used in conjunction with on-site electric heating and an automatic tightening spring to complete tension calibration and eliminate the influence of temperature changes on measurement accuracy.
