Abstract
Description
A type of electronic fence for campus security Technical Field
[0001] This utility model relates to the field of campus security technology, and in particular to a campus security electronic fence. Background Technology
[0002] Electronic fences are the most advanced perimeter security alarm systems, mainly composed of three parts: an electronic pulse generator, front-end accessories, and a back-end control system. Typically, the electronic pulse generator is installed outdoors along the existing perimeter wall (such as a brick wall, concrete wall, or iron fence). The pulse generator itself is also usually outdoors, transmitting alarm signals to the control keyboard at the back-end control center via signal transmission equipment. This displays the zone's operational status and allows for remote arming and disarming control of the external pulse generator.
[0003] In the existing technology, schools usually use facial recognition at the gate and electronic fences on brick walls to prevent students or outsiders from entering and leaving the campus. However, the electronic fences used are generally single-unit structures, and the metal blocking lines of the electronic fences are set to one side. This makes it easy for students or outsiders to avoid the electronic fences when climbing over the brick walls, which reduces the security effect of the electronic fences. Summary of the Invention
[0004] The present invention aims to provide a campus security electronic fence to overcome or at least partially solve the above-mentioned problems.
[0005] To achieve the above objectives, the technical solution of this utility model is specifically implemented as follows:
[0006] This utility model provides a campus security electronic fence, including a metal blocking line, a pulse host, and a microprocessor terminal. The pulse host is connected to the metal blocking line and the microprocessor terminal respectively through wires. Two sets of metal blocking lines are provided, and the two sets of metal blocking lines are symmetrically installed on two sets of rotating arms and pass through the rotating arms. A rotating disk is fixedly connected to the lower part of the rotating arm. The rotating disk is installed on a fixed base and is rotatably connected to the fixed base through a rotating shaft. The fixed base is welded and fixed to a fixed frame. Multiple positioning slots are formed in a ring array on the outer periphery of the fixed base. Positioning pins are connected to the rotating disk, and the external parts of the positioning pins are matched and set on the positioning slots.
[0007] As a further embodiment of this utility model, the fixing frame has a U-shaped structure, and pin holes are provided on both the left and right sides of the fixing frame.
[0008] As a further embodiment of this invention, a metal rod is connected between the pulse generator and the metal blocking line, and the metal rod is buried in the ground.

[0016] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
[0017] Referring to Figures 1-4, an embodiment of the present invention provides a campus security electronic fence, including a metal blocking line 4, a pulse host 6, and a microprocessor terminal 7. The pulse host 6 is connected to the metal blocking line 4 and the microprocessor terminal 7 respectively through wires. Two sets of metal blocking lines 4 are provided, and the two sets of metal blocking lines 4 are symmetrically installed on two sets of rotating arms 3 and pass through the rotating arms 3. A rotating disk 5 is fixedly connected to the lower part of the rotating arm 3. The rotating disk 5 is installed on the fixed base 2 and is rotatably connected to the fixed base 2 through a rotating shaft. The fixed base 2 is welded and fixed to the fixed frame 1. Multiple positioning slots 21 are opened in a ring array on the outer periphery of the fixed base 2. Positioning pins 51 are connected to the rotating disk 5, and the external parts of the positioning pins 51 are matched and set on the positioning slots 21.
[0018] The fixing frame 1 has a U-shaped structure, and pin holes are provided on both the left and right sides of the fixing frame 1. The U-shaped structure design allows the fixing frame 1 to be fitted onto the brick wall, and the explosion-proof bolts pass through the pin holes and connect to the brick wall, thereby fixing the fixing frame 1 to the brick wall.
[0019] A metal rod is also connected between the pulse generator 6 and the metal blocking line 4, and the metal rod is buried in the ground to achieve the purpose of grounding.
[0020] In use, the metal blocking wires 4 are first installed through the rotating arm 3, with three wires in each group, all placed on the same side. Then, the two groups of metal blocking wires 4 and the rotating arm 3 are installed on the left and right fixed seats 2, respectively. The fixing frame 1 is then fixed to the top of the brick wall, and the metal blocking wires 4 are connected to the pulse host 6 and the microprocessor terminal 7. Then, as needed, the left rotating arm 3 is rotated outward around the central axis of the rotating shaft, and the right rotating arm 3 is rotated outward around the central axis of the rotating shaft. The rotating arm 3 is then positioned using the positioning pin 51, which enables the two groups of rotating arms 3 and metal blocking wires 4 to be deployed in opposite directions. This allows for simultaneous blocking and interception of the top of the brick wall from the left and right sides, increasing the difficulty for students and outsiders to climb over the wall and improving the security effect.
[0021] The pulse generator 6 is installed in an outdoor stainless steel rainproof box to protect it. When the electronic fence is working, the pulse generator 6 is connected to an external power source and transmits pulses to the metal barrier line 4.
[0022] The pulse generator 6 and the metal barrier wire 4 create a circuit upon contact with a person or object. The power exciter in the pulse generator 6 then converts the power into brief, high-voltage pulses, which are transmitted to the exposed metal barrier wire 4, releasing an electrical pulse approximately once per second. Contact with the metal barrier wire 4 during this pulse completes the circuit and triggers the shock, causing an electric shock. The impact depends on the voltage, the energy of the pulse, the degree of contact between the receiver and the fence and ground, and the path of the current through the body; it can range from barely noticeable to uncomfortable, painful, or even fatal.
[0023] The pulse generator 6 also transmits the alarm signal to the back-end microprocessor terminal 7 through the signal transmission device and performs the alarm operation.
[0024] The above are merely embodiments of this application and are not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
