[0002] The security electronic fence, also known as the electronic perimeter alarm system, is an advanced perimeter protection technology. It constructs an invisible protection barrier through a series of sensors and communication devices to detect and alarm intruders in real time. The security electronic fence mainly consists of three parts: a front-end detection device, an alarm host, and a back-end management software. The front-end detection device usually includes an electronic fence host, a tension electronic fence, a pulse electronic fence, etc. These devices form a closed loop through buried cables or metal nets installed on the wall to form an insurmountable protection area. When an intruder attempts to cross or damage the protection area, the detection device will immediately sense the change and transmit the alarm signal to the alarm host. After receiving the alarm signal, the alarm host will immediately activate the audible and visual alarm and transmit the alarm information to the back-end management software through the network. However, this electronic fence still has the following defects: during the use of the electronic fence, after the safety warning sign has been exposed to wind and rain for a long time, the surface is easily damaged. Therefore, when replacing the warning sign, the existing warning sign is assembled by bolts and other methods during installation, and the installation process is relatively complex, and the later disassembly and maintenance efficiency is relatively low.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figure 1-7 , the present utility model provides the following technical solutions: An electronic fence for security includes a terminal stress rod and an alloy wire. The bottom end of the terminal stress rod is installed on the surface of the wall. An alloy wire is connected to the surface of the terminal stress rod. The other end of the alloy wire is connected to an intermediate rod. A warning sign is connected to the surface of the alloy wire;

[0024] A hook is connected to the back side of the warning sign. A positioning plate is connected to the center of the back side of the warning sign. A hinge is connected to the surface of the positioning plate. The other side of the hinge is connected to an upper cover plate. An insertion block is connected to the bottom surface of the upper cover plate. Elastic buckles are connected to the openings on both sides of the insertion block.

[0025] Preferably: An alarm is installed on the outer wall of the wall. A terminal insulator is installed at the bottom end of the terminal stress rod. A power distribution cabinet is installed on the outer wall of the wall.

[0026] Preferably: The notch of the hook and the notch on the surface of the positioning plate are at the same height. The insertion block and the elastic buckles are both made of plastic. The elastic buckles are of a plastic structure.

[0027] During specific use, the warning sign can be conveniently installed by inserting the insertion block into the opening on the surface of the positioning plate.

[0028] Preferably: Slots adapted to the insertion blocks are formed on the surface of the positioning plate, and the elastic buckle and the opening inside the slot form an elastic clamping structure.

[0029] During specific use, by elastically deforming the elastic buckle, it is convenient to snap the elastic buckle into the inside of the slot, thereby facilitating the stable installation of the upper cover plate.

[0030] Preferably: A sleeve is connected to the top end of the middle rod, a docking seat is connected to the top end of the sleeve, a limiting block is connected to the inner wall of the docking seat, and the limiting block and the opening at the bottom end of the heightening rod form a sliding fit structure.

[0031] During specific use, by sliding the opening at the bottom end of the heightening rod along the limiting block, it is convenient to stably dock the heightening rod on the surface of the docking seat.

[0032] Preferably: A screw rod is threadedly connected to the surface of the docking seat, the other end of the screw rod is connected to a top plate, and the curvature of the surface of the top plate matches the curvature of the surface of the heightening rod.

[0033] During specific use, by rotating the screw rod, it is convenient to drive the top plate to move, facilitating the stable installation of the heightening rod.

[0034] The working principle of the present utility model during specific use: First, assemble the terminal stress rod and the middle rod on the wall. Then, assume the alloy wire and conduct electricity. Specifically, after the pulse generator is powered on during operation, it will send a pulse voltage to the front-end fence, emitting once every approximately 1.5 seconds. The pulse stays on the fence for approximately 0.1 seconds. After a circuit is formed on the front-end fence, the pulse returns to the receiving port of the host. This port receives the feedback pulse signal. At the same time, the host also detects the resistance value between the two transmitting ends. If the front-end fence is damaged, resulting in an open circuit or a short circuit, and the receiving port of the pulse host cannot receive the pulse signal or the resistance between the two transmitting ends is too small, the host will issue an alarm. Then, by changing the installation method of the warning sign, specifically, hang the hook on the back of the warning sign on the alloy wire. Then, rotate the upper cover on the surface of the positioning plate, causing the hinge to rotate. At the same time, insert the plug into the slot on the surface of the positioning plate, and the elastic buckle deforms. Then, it returns to its original position, causing the elastic buckle to engage with the opening of the inner wall of the slot, assembling the warning sign by means of buckling, improving the convenience of assembling the warning sign, and at the same time improving the efficiency of later disassembly and maintenance, enhancing the electrical safety. In addition, by adding a docking seat, it is installed at the top of the middle rod through a sleeve. Then, insert the bottom end of the heightening rod into the docking seat, causing the opening at the bottom end of the heightening rod to slide along the limiting block. Then, rotate the screw rod so that the top plate is in stable contact with the heightening rod. The height of the fence can be increased according to security needs without completely disassembling and replacing the new pole, improving the flexibility of the fence during security protection and facilitating the improvement of security efficiency.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
