Description
Technical Field
[0001] This utility model belongs to the field of electronic fences, and in particular relates to a security device that uses electronic fences. Background Technology
[0002] An electronic fence is an advanced perimeter security alarm system, consisting of an electronic fence control unit and front-end detection fences. The control unit generates and receives high-voltage pulse signals and triggers an alarm when the front-end detection fence is in a state of contact with the wire, short circuit, or open circuit, simultaneously sending an intrusion signal to the security alarm center. The front-end detection fence is a physical perimeter composed of poles and metal wires. Multi-level networking can be achieved through a control keyboard or software. An electronic fence is an active intrusion prevention fence that counters intrusion attempts, repelling intruders, delaying intrusion time, and not threatening human life. It also sends intrusion signals to security monitoring equipment, ensuring that management personnel can promptly understand the situation in the alarm area and take rapid action.
[0003] Currently, most electronic fences in China are installed along existing walls (such as brick walls, cement walls, or iron fences), i.e., wall-top electronic fences. They offer high security and do not occupy surrounding land. However, these walls are generally quite long, requiring security personnel to spend a considerable amount of time locating the alarm trigger point. This can lead to security personnel being unable to promptly resolve the alarm's cause. Although some areas have surveillance cameras installed, by the time they review the footage, the intruder may have already entered the fence and disappeared from the camera's view. In this case, security personnel would have to review the surveillance footage one by one to find the alarm trigger point. Therefore, there is a need for a technology that, in addition to applying electronic fence technology, can also quickly alert security personnel to the location of the alarm trigger point when an intruder triggers the electronic fence alarm. Utility Model Content
[0004] The purpose of this invention is to provide a security device that uses an electronic fence, which can quickly alert security personnel to the location of the alarm trigger point when an intruder triggers the electronic fence alarm.
[0005] The security equipment using an electronic fence includes a first fence, with an electronic fence installed on the top left of the first fence. A second fence is fixed to the top right of the first fence. Several trigger plates are arranged in a front-to-back pattern on the top of the second fence. Pressure sensors are installed in the area below each trigger plate on the top of the second fence. Each trigger plate is mounted on the upper end of the second fence by a spring support assembly. The spring support assembly allows the trigger plate to move up and down relative to the top of the second fence and ensures that there is a gap between the trigger plate and the corresponding pressure sensor when the trigger plate is stationary. A fixed rod is installed on the left end of the first fence. A monitoring camera for capturing the situation around the first fence and an audible and visual alarm for issuing an alarm when the pressure sensor senses pressure are mounted on the fixed rod.
[0006] Furthermore, the spring support assembly includes several telescopic rods fixed to the bottom of the trigger plate. A cavity is provided in the upper end of the second wall. The lower end of each telescopic rod independently passes through the top of the second wall and is fixed to the bottom of the cavity. A spring is independently fitted on each telescopic rod. One end of the spring is fixed to the bottom of the trigger plate, and the other end is fixed to the bottom of the cavity. When the spring is in a stationary state, there is a certain gap between the bottom of the trigger plate and the sensing end of the pressure sensor.
[0007] Furthermore, both the left and right walls of the trigger plate are fixed with side plates for blocking the gap between the trigger plate and the second wall.
[0008] Furthermore, the first enclosure includes a lower retaining wall and an upper retaining wall. The upper retaining wall is fixed to the top of the lower retaining wall by several columns. Several iron railings are vertically arranged between two connected columns, with equal spacing between them. One end of each iron railing is fixed to the lower retaining wall, and the other end is fixed to the upper retaining wall.
[0009] Furthermore, a warning sign is fixed to the right side wall of the second fence.
[0010] Furthermore, the second wall has an overall structure that slopes upwards and to the right.
[0011] Furthermore, the distance between two adjacent trigger plates is less than 0.5 cm.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] This invention utilizes a trigger plate and pressure sensor at the top of the second fence to detect intruders before they touch or damage the electronic fence. Security personnel can then quickly pinpoint the location of the alarm trigger via surveillance camera footage and an audible and visual alarm. This allows them to quickly understand the cause of the alarm and respond promptly. Furthermore, it can eliminate alarms caused by animal contact before the audible and visual alarm sounds, reducing unnecessary patrols. The trigger plate is connected to the second fence via a spring support assembly, allowing it to move up and down relative to the top of the second fence. The spring support assembly also increases the lower limit of the pressure required for the trigger plate to contact the pressure sensor, preventing birds, insects, and other animals from landing on the trigger plate and causing frequent pressure readings, thus reducing the workload of security personnel.

Detailed Implementation
[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
[0019] Example 1
[0020] This embodiment describes a security device using an electronic fence, which includes a first wall 1. An electronic fence 5 is installed on the top left of the first wall 1. The first wall 1 is connected end to end and encloses the protected area, blocking intruders. The electronic fence 5 is installed on top of the electronic fence 5. If an intruder wants to climb over the first wall 1, he will inevitably touch or damage the electronic fence 5. Once the fence is touched or damaged, causing an open circuit or short circuit, the receiving port of the pulse host will not receive the pulse signal or the resistance between the two transmitting ends will be too small. The host will then issue an alarm to remind security personnel that someone has climbed over the wall.
[0021] like Figure 1 and Figure 3 As shown, the first enclosure 1 includes a lower retaining wall 1.1 and an upper retaining wall 1.4. The upper retaining wall 1.4 is fixed to the top of the lower retaining wall 1.1 by several columns 1.3. Several iron railings 1.2 are vertically arranged between two connected columns 1.3, with equal spacing between them. One end of each iron railing 1.2 is fixed to the lower retaining wall 1.1, and the other end is fixed to the upper retaining wall 1.4. In this embodiment, the first enclosure 1 composed of the lower retaining wall 1.1, iron railings 1.2, columns 1.3, and upper retaining wall 1.4 can have high strength and a large top installation area, while also reducing construction costs and shortening the construction period to a certain extent compared to pure cement walls and brick walls.
[0022] A second wall 6 is fixed to the top right of the first wall 1. Several trigger plates 9 are arranged in a front-to-back pattern above the second wall 6. Pressure sensors 10 are installed on the area below each trigger plate 9 at the top of the second wall 6. In this embodiment, the left side of the first wall 1 is the protected area, and an intruder must climb over the right side of the first wall 1 to enter. Therefore, when climbing over the first wall 1, the intruder will first climb over the second wall 6 and then over the electronic fence 5. During the process of climbing over the second wall 6, downward pressure will inevitably be applied to the trigger plates 9. At this time, the pressure sensors 10 will sense the change in pressure. Therefore, the trigger plates 9 and pressure sensors 10 at the top of the second wall 6 can detect the intruder's intrusion behavior before the intruder touches or damages the electronic fence 5. Figure 3 As shown, the distance between two adjacent trigger plates 9 is less than 0.5 cm. The tiny gap between the two adjacent trigger plates 9 allows each trigger plate 9 to operate independently, and also restricts the intruder from having to use the trigger plate 9 to climb over the second wall 6, thus ensuring that the device can detect the intruder's illegal behavior in advance.
[0023] refer to Figure 3 A warning sign 12 is fixed on the right side wall of the second perimeter wall 6. In this embodiment, the warning sign 12 can initially warn and deter intruders.
[0024] Each trigger plate 9 is mounted on the upper end of the second wall 6 via a spring support assembly. The spring support assembly allows the trigger plate 9 to move up and down relative to the top of the second wall 6 and ensures that a gap remains between the trigger plate 9 and the corresponding pressure sensor 10 when the trigger plate 9 is stationary. Figure 1 and Figure 2 As shown, the spring support assembly includes several telescopic rods 11 fixed to the bottom of the trigger plate 9. A cavity is opened in the upper end of the second enclosure 6. The lower end of each telescopic rod 11 independently passes through the top of the second enclosure 6 and is fixed to the bottom of the cavity. A spring 7 is independently fitted on each telescopic rod 11. One end of the spring 7 is fixed to the bottom of the trigger plate 9, and the other end is fixed to the bottom of the cavity. When the spring 7 is in a stationary state, there is a certain gap between the bottom of the trigger plate 9 and the sensing end of the pressure sensor 10. In this embodiment, the spring support assembly can not only connect the trigger plate 9 and the second enclosure 6, allowing the trigger plate 9 to move up and down relative to the top of the second enclosure 6, but also increase the lower limit of the pressure required for the pressure sensor 10 to touch the pressure sensor 10, thereby avoiding the situation where birds, insects, and other animals land on the trigger plate 9 and cause the pressure sensor 10 to frequently sense pressure, thus reducing the workload of security personnel. In practical applications, the minimum pressure sensed by the trigger pressure sensor 10 can be 5-10N.
[0025] refer to Figure 1 , Figure 2 and Figure 3 Both the left and right sides of the trigger plate 9 are fixed with side plates 8 to cover the gap between the trigger plate 9 and the second wall 6. In this embodiment, the side plates 8 can prevent the body from being supported by the gap between the trigger plate 9 and the second wall 6, and also prevent rainwater from falling on the surface of the pressure sensor 10 and corroding the pressure sensor 10.
[0026] A fixed rod 2 is installed at the left end of the first fence 1. A monitoring camera 4 for capturing images of the area around the first fence 1 and an audible and visual alarm 3 for triggering an alarm when the pressure sensor 10 senses pressure are mounted on the fixed rod 2. In this embodiment, the monitoring footage from the camera 4 and the audible and visual alarm 3 allow security personnel to quickly pinpoint the location triggering the alarm, facilitating a rapid understanding of the cause of the alarm and prompt arrival at the scene. Simultaneously, it can eliminate alarms caused by animal contact when the audible and visual alarm 3 does not sound, reducing unnecessary patrols. Figure 1 As shown, an L-shaped fixing rod 2 is fixed to the left side wall of the upper retaining wall 1.4. The audible and visual alarm 3 and the monitoring camera 4 are both installed on the fixing rod 2. In actual application, a monitoring camera 4 and an audible and visual alarm 3 are set at intervals. Each audible and visual alarm 3 is electrically connected to a microprocessor through a wire. The pressure sensor 10 at the top of the upper retaining wall 1.4 that is closest to the audible and visual alarm 3 is electrically connected to the microprocessor through a wire. Thus, an audible and visual alarm 3 is responsible for an area, while the monitoring camera 4 in an adjacent area monitors that area.
[0027] In this embodiment, a first wall 1 is first built to enclose the protected area. Then, a second wall 6 is built on top of the first wall 1, and an electronic fence 5 is installed. A monitoring camera 4 and an audible and visual alarm 3 are installed at every other end. When an intruder wants to enter the protected area, he will first climb over the first wall 1 and onto the top of the second wall 6. At this time, due to the pressure of the intruder on the trigger plate 9, the spring 7 will be compressed, and the trigger plate 9 will move down and exert pressure on the pressure sensor 10. Then, the audible and visual alarm 3 will be triggered. If the intruder continues to break in, he will touch or damage the electronic fence 5. At this time, the alarm of the security center will be triggered. Security personnel can determine which area has been invaded by checking the status of the audible and visual alarm 3 on the monitoring screen, so that they can quickly rush to the scene.
[0028] Example 2
[0029] This embodiment further illustrates the technology. The second enclosure 6 has a structure that slopes upwards and to the right. Figure 1As shown, this embodiment increases the difficulty for intruders to climb the first wall 1 by fixing the second wall 6 to the top of the first wall 1 in an inclined position facing the upper right, thereby reducing the probability of intruders ignoring the warning signs and forcibly entering the wall.
