When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0035] As attached Figure 1 -Appendix Figure 7 As shown, this utility model provides a fence-climbing detection and early warning device, including a main body 1, a sensing mechanism 2, an alarm mechanism 3, and a battery 4 and a controller 5 electrically connected to the sensing mechanism 2 and the alarm mechanism 3. The main body 1 integrates the sensing mechanism 2, the alarm mechanism 3, the battery 4, and the controller 5 into one unit, ensuring the integrity of the device. It also simplifies installation by allowing the sensing mechanism 2, the alarm mechanism 3, the battery 4, and the controller 5 to be mounted together on the fence 6. The sensing mechanism 2 senses whether there are people near the fence 6, thus determining if someone is preparing to climb over it, or whether someone is currently climbing over the fence 6. The alarm mechanism 3 sounds an alarm when it detects someone preparing to or currently climbing over the fence 6, thus preventing the climber from doing so and alerting nearby staff. The battery 4 supplies power to the sensing mechanism 2, the alarm mechanism 3, and the controller 5. The controller 5 receives signals from the sensing mechanism 2 and controls the alarm mechanism 3 to sound an alarm when the sensing mechanism 2 detects someone preparing to or currently climbing over the fence 6.

[0036] The main body 1 includes a mounting base plate 11, a connector 12, and a mounting side plate 13. The mounting base plate 11 is installed between the bottom of the post 61 of the guardrail 6 and the bottom of the mounting groove 621 of the base 62. In this case, the mounting base plate 11 is confined within the mounting groove 621 of the base 62, providing excellent installation stability and ensuring the reliable fixation of the entire guardrail crossing detection and early warning device to the guardrail 6. It reliably adapts to harsh environments such as vibration and strong winds in the installation environment of the guardrail 6. Furthermore, when a pressure sensor 21 is installed at the bottom of the mounting base plate 11, the weight of a person supporting the guardrail 6 can be applied to the pressure sensor 21 to detect whether someone is crossing the guardrail 6. The mounting side plate 13 is installed on the side of the guardrail 6 above the base 62, where the post 61 is located. The mounting side plate 13 is used to install the human proximity sensor 22 and the alarm mechanism 3 in the sensing mechanism 2, allowing the human proximity sensor 22 to easily detect human movement and enabling the alarm mechanism 3 to provide a clear and conspicuous alarm. The connector 12 is used to install to the side of the post 61 of the guardrail 6, and to connect the mounting base plate 11 and the mounting side plate 13. The connector 12 is used to ensure the integrity of the mounting base plate 11 and the mounting side plate 13, and to simplify the overall installation difficulty.

[0037] The sensing mechanism 2 includes a pressure sensor 21 disposed at the bottom of the mounting base plate 11 and / or a human proximity sensor 22 disposed on the mounting side plate 13 and arranged facing the front / rear of the guardrail 6. Preferably, the sensing mechanism 2 includes a pressure sensor 21 and a human proximity sensor 22, thereby realizing a dual alarm for both preparation to climb over and current climbing over. Specifically, when the human proximity sensor 22 detects that someone is within a set distance of the guardrail 6 and stays for a set time, it determines that someone is preparing to climb over the guardrail. At this time, the audible alarm 31 can play a warning voice such as "Climbing over is prohibited. Please stay away from the guardrail and pay attention to safety" and turn on the warning light 32. When the pressure sensor 21 detects a sudden increase in pressure, it determines that someone is climbing over the guardrail 6. At this time, the audible alarm 31 can play a warning voice such as "Danger! Please stop climbing over" and turn on the warning light 32.

[0038] The alarm mechanism 3 includes a sound alarm 31 and / or a warning light 32 arranged on the mounting side plate 13. Preferably, the alarm mechanism 3 includes a sound alarm 31 and a warning light 32 to improve the warning effect. The sound alarm 31 can be used to broadcast a warning voice or to play a warning sound effect, depending on the actual needs.

[0039] The fence-climbing detection and early warning device provided by this utility model can issue an alarm for actions that are about to be or are in the process of climbing over the fence. Its well-integrated structure makes it compact and reliable, allowing for convenient and quick installation onto existing fences 6 without requiring modifications. This significantly reduces the cost of deployment and facilitates widespread adoption. Furthermore, the device is stable and reliable once installed on the fence 6, making it suitable for harsh environments where the fence 6 is located.

[0040] In one embodiment, a fitting block 111 is provided above the mounting base plate 11 and fitted into the hollow of the post 61 of the guardrail 6. In this embodiment, by providing the fitting block 111, the fixing stability of the mounting base plate 11 and the post 61 can be improved, further enhancing the installation stability of the guardrail crossing detection and warning device. On the other hand, the guardrail crossing detection and warning device can be pre-installed on the post 61 and then installed on the base 62 in conjunction with the post 61, simplifying the installation process. Specifically, the fitting block 111 can first be embedded into the bottom of the post 61, at which point the mounting base plate 11 abuts against the bottom surface of the post 61. Then, the connector 12 and the mounting side plate 13 are fixed to the side wall of the post 61. Finally, the post 61 is inserted into the mounting groove 621 of the base 62 to complete the installation. Furthermore, the fitting block 111 can also improve the structural strength of the bottom of the post 61, thereby improving the structural stability of the guardrail 6.

[0041] In one embodiment, the interlocking block 111 is hollow inside and open at the top. That is, the interlocking block 111 is a structure of four rectangularly arranged side plates, which, together with the mounting base plate 11, form a hollow space. The hollow space of the interlocking block 111 is used to install the battery 4 and the controller 5. In this embodiment, the battery 4 and controller 5 are installed inside the hollow space, ultimately located in the bottom hollow space of the column 61. This makes reasonable use of the structural and installation space of the fence-climbing detection and warning device, ensuring a compact structure and preventing any additional increase in the external dimensions of the fence 6 after installation. Furthermore, the column 61 provides physical protection for the battery 4 and controller 5 against dust, water, and impact, reducing the waterproofing requirements of the battery 4 and controller 5 and lowering costs.

[0042] In one embodiment, the connector 12 includes power and signal transmission lines. Preferably, the power and signal transmission lines adopt a ribbon cable structure. The human proximity sensor 22 and the alarm mechanism 3 are electrically connected to the battery 4 and controller 5 inside the hollow of the interlocking block 111 via the power and signal transmission lines. In this embodiment, the connector 12 is used both to connect the mounting base plate 11 and the mounting side plate 13 and to realize power and signal transmission.

[0043] In one embodiment, the connector 12 further includes a wear-resistant layer covering the outside of the power and signal transmission lines. Since a portion of the connector 12 is located on the outer wall of the column 61 and the side wall of the mounting groove 621 of the base 62, friction will occur. By providing a wear-resistant layer, damage to the power and signal transmission lines can be avoided, thus improving their service life.

[0044] In one embodiment, the mounting side plate 13 is also provided with a power supply structure for charging the battery 4, thereby simplifying the charging process. Preferably, the charging mechanism can be a charging interface, which can be connected to a power supply device such as AC power, a charging power source, or a solar power supply, and the specific choice can be made as needed. In other embodiments, a power supply mechanism may not be provided, and the battery 4 can be directly replaced for power replenishment.

[0045] In one embodiment, the connectors 12 and mounting side plates 13 are arranged in a rectangular array of four groups;

[0046] The mounting side plates 13 located on the front and rear sides of the post 61 of the guardrail 6 are used to install human proximity sensors 22, which can then monitor whether pedestrians are approaching the guardrail 6 in the front and rear directions.

[0047] The mounting side plates 13 located on the left and right sides of the post 61 of the guardrail 6 are used to install the alarm mechanism 3, so as to make reasonable use of the side wall space of the post 61. Preferably, each of the two mounting side plates 13 located on the left and right sides of the post 61 is equipped with a sound alarm 31 and a warning light 32 to improve the alarm effect.

[0048] In one embodiment, the mounting side plate 13 is fixedly connected to the side wall of the post 61 of the guardrail 6 via a fastening structure. This serves to secure the mounting side plate 13 to the post 61. Specifically, the fastening mechanism can be bolts or an adhesive layer attached to the inner wall of the mounting side plate 13, which then adheres to the post side wall, greatly simplifying the installation process.

[0049] This utility model also provides a guardrail system, including a guardrail 6 and the aforementioned guardrail crossing detection and early warning device. The guardrail 6 includes at least two sets of parallel posts 61, each post 61 having a detachable base 62 at its bottom, and a guardrail body 63 between adjacent posts 61. At least one base 62 is equipped with a guardrail crossing detection and early warning device; preferably, each base 62 is equipped with a guardrail crossing detection and early warning device to improve the monitoring and alarm range.

[0050] In one embodiment, the mounting groove 621 of the base 62 of the guardrail 6 has a receiving groove 622 for accommodating the connector 12. In this embodiment, the size of the connector 12 is smaller than the size of the receiving groove 622, allowing the connector 12 to be movably arranged within the receiving groove 622. By providing the receiving groove 622, on the one hand, the connector 12 can be prevented from jamming the column 61 within the mounting groove 621, thereby reducing the sensing accuracy of the pressure sensor 21. On the other hand, it can prevent the mounting groove 621 and the column 61 from causing frictional wear on the connector 12, thus improving its service life. This embodiment is a preferred method and involves minor modifications to the base 62.

[0051] The above description is merely an embodiment and does not constitute any limitation on this utility model. Any person skilled in the art can make many possible variations, modifications, or alterations to the technical solution of this utility model without departing from its scope. Therefore, any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model, without departing from its scope, should fall within the protection scope of this utility model.
