Technical Field

[0001] This utility model belongs to the field of security monitoring technology, and in particular relates to a low-current remote alarm fence. Background Technology

[0002] With the rapid development of the social economy, the construction of various new energy projects, water conservancy and hydropower projects, electrical engineering projects and civil engineering projects is constantly advancing. These projects face many safety challenges during construction and operation, such as equipment theft, illegal intrusion, and personnel accidentally entering dangerous areas. These problems may not only lead to property losses, but also cause safety accidents and threaten the safety of people's lives.

[0003] Traditional security measures typically employ physical fences and manual patrols. While physical fences can provide some protection, their effectiveness against organized theft or vandalism is limited. Manual patrols, on the other hand, require a significant manpower investment and are difficult to maintain 24 / 7, often resulting in blind spots. Furthermore, in remote areas or harsh environments, manual patrols are even more challenging and costly.

[0004] This invention designs a low-current remote alarm fence to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A low-current remote alarm fence includes a negative base post, a positive base post, a fence wire assembly, an alarm device, and a power generation device. The fence wire assembly is installed between the negative base post and the positive base post, the alarm device is installed on the positive base post, and the power generation device is connected to the alarm device.

[0007] The alarm device is equipped with a microcontroller, a monitoring component, and an audible and visual alarm component. The monitoring component is connected to the fence wire assembly and the microcontroller, and includes a Hall current sensor and a resistance monitoring module.

[0008] As a preferred embodiment, the negative electrode base column is provided with a longitudinally extending groove, and a number of interconnecting conductive plates are installed in the groove at intervals. The positive electrode base column is provided with an insulating isolation strip and a number of sets of interconnecting conductive plates arranged longitudinally at intervals. The interconnecting conductive plate sets include positive and negative interconnecting conductive plates distributed diagonally. The positive and negative interconnecting conductive plates are located on the left and right sides of the insulating isolation strip, respectively. One end of the fence conductor group is connected to the interconnecting conductive plate, and the other end of the fence conductor group is connected to the positive and negative interconnecting conductive plates.

[0009] As a preferred embodiment, the fence conductor group includes several horizontal conductor groups, which are arranged longitudinally between the negative electrode base post and the positive electrode base post. Each horizontal conductor group includes a first horizontal conductor and a second horizontal conductor distributed vertically. One end of the first horizontal conductor and the second horizontal conductor in the same group are connected to the same connecting conductor, and the other end of the first horizontal conductor and the second horizontal conductor in the same group are respectively connected to the positive electrode connecting conductor and the negative electrode connecting conductor in the same group.

[0010] As a preferred embodiment, the fence conductor group also includes several longitudinal conductors, which are arranged laterally between the negative and positive base posts and are connected to the transverse conductor group. The first and second transverse conductors are both exposed metal conductors, while the longitudinal conductors are fully insulated conductors.

[0011] As a preferred option, the power generation device is an axial flow wind power generation device, and the alarm device is equipped with a battery and a charging management module, with the power generation device connected to the charging management module.

[0012] As a preferred option, the audible and visual alarm component includes an audible alarm, a flashlight, a wireless communication module, and an alarm controller.

[0013] As a preferred option, a monitoring camera device is also included, which is connected to the microcontroller.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] 1. When an external object comes into contact with the fence conductor group, it causes a change in the resistance within the fence conductor group, which in turn causes a change in current. After the Hall current sensor detects the current fluctuation, the microcontroller triggers the operation of the audible and visual alarm component to achieve the alarm purpose. This monitoring method based on current changes has high sensitivity and high reliability, which can effectively prevent external damage and illegal intrusion, ensure the safe operation of electrical equipment, reduce power outages caused by safety accidents, and improve the stability of the power grid and the reliability of power supply.

[0022] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following embodiments or drawings are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0023] A low-current remote alarm fence, such as Figures 1 to 5 As shown, it includes a negative base column 1, a positive base column 2, a fence wire assembly 3, an alarm device 4, and a power generation device 5. The fence wire assembly 3 is installed between the negative base column 1 and the positive base column 2. The alarm device 4 is installed on the positive base column 2. The power generation device 5 is connected to the alarm device 4.

[0024] The alarm device 4 is equipped with a microcontroller, a monitoring component, and an audible and visual alarm component. The monitoring component is connected to the fence wire group 3 and the microcontroller respectively. The monitoring component includes a Hall current sensor and a resistance monitoring module.

[0025] The microcontroller is used to process the signals from the Hall current sensor and the resistance monitoring module and to control the audible and visual alarm components. The Hall current sensor is used to monitor the current changes in the fence wire group 3. The resistance monitoring module monitors the resistance value changes in real time through a Wheatstone bridge and an amplifier. Information transmission between the devices is carried out through fiber optic or wireless communication.

[0026] This device can be installed around hazardous areas, such as deep foundation pits and high slopes. When personnel or objects accidentally enter, the alarm device 4 can promptly issue an alarm to remind on-site personnel to pay attention to safety, and at the same time notify management personnel to take appropriate measures to avoid safety accidents.

[0027] This device uses a safe voltage such as 12V or 24V and is equipped with a leakage protection device at the power supply end to prevent injury or death when an external object comes into contact with it. Its alarm principle is that any external object will have resistance. When an external object comes into contact with the fence wire group 3, it will cause the resistance inside the fence wire group 3 to change, thereby causing a change in current. After the Hall current sensor detects the current fluctuation, the microcontroller triggers the sound and light alarm component to run, thus achieving the alarm purpose.

[0028] This current-change-based monitoring method is highly sensitive and reliable, effectively preventing external damage and illegal intrusion, ensuring the safe operation of electrical equipment, reducing power outages caused by safety accidents, and improving the stability and reliability of the power grid.

[0029] The negative electrode base column 1 and the positive electrode base column 2 are made of carbon fiber or environmentally friendly rigid plastic. When there are more than two negative electrode base columns 1 and positive electrode base columns 2, the negative electrode base columns 1 and positive electrode base columns 2 are arranged alternately.

[0030] The negative electrode base column 1 is provided with a longitudinally extending groove 11, and a number of spaced connecting conductors 12 are installed in the groove 11. The positive electrode base column 2 is provided with an insulating isolation strip 21 and a number of sets of longitudinally spaced connecting conductors. The connecting conductors include diagonally distributed positive connecting conductors 23 and negative connecting conductors 24. The positive connecting conductors 23 and negative connecting conductors 24 are located on the left and right sides of the insulating isolation strip 21, respectively. One end of the fence conductor group 3 is connected to the connecting conductors 12, and the other end of the fence conductor group 3 is connected to the positive connecting conductors 23 and negative connecting conductors 24.

[0031] Insulating strip 21 separates the positive connecting piece 23 and the negative connecting piece 24 to prevent short circuit between the positive connecting piece 23 and the negative connecting piece 24.

[0032] The fence conductor group 3 includes several horizontal conductor groups, which are arranged longitudinally between the negative electrode base post 1 and the positive electrode base post 2. Each horizontal conductor group includes a first horizontal conductor 32 and a second horizontal conductor 33 distributed vertically. One end of the first horizontal conductor 32 and the second horizontal conductor 33 in the same group is connected to the same connecting conductor 12, and the other end of the first horizontal conductor 32 and the second horizontal conductor 33 in the same group are respectively connected to the positive electrode connecting conductor 23 and the negative electrode connecting conductor 24 in the same group.

[0033] There are four sets of transverse conductors. The number of connecting conductors 12 and connecting conductors is the same and there are at least four sets. Connecting conductors 12, first transverse conductors 32, positive connecting conductors 23, monitoring components, negative connecting conductors 24, and second transverse conductors 33 form a loop, ultimately forming four loops.

[0034] The first horizontal conductor 32, the second horizontal conductor 33, and the connecting conductor 12, the positive connecting conductor 23, and the negative connecting conductor 24 are fixed by soldering and bolting.

[0035] The fence conductor group 3 also includes several longitudinal conductors 34, which are arranged laterally between the negative base post 1 and the positive base post 2. The longitudinal conductors 34 are connected to the transverse conductor group. The first transverse conductor 32 and the second transverse conductor 33 are both exposed metal conductors. The longitudinal conductors 34 are fully insulated conductors. The longitudinal conductors 34 are not electrically connected to the transverse conductor group, so there will be no short circuit.

[0036] The longitudinal guide 34 serves two purposes: firstly, it reduces the gaps within the transverse guide group, preventing small animals from crossing the fence guide group 3; secondly, it increases the connection strength of the transverse guide group, preventing damage to the transverse guide group when external objects come into contact with it.

[0037] The power generation device 5 is an axial flow wind power generation device. The blades of the axial flow wind power generation device are made of alloy metal, which is lightweight, has high hardness, and is corrosion resistant.

[0038] The alarm device 4 is equipped with a storage battery and a charging management module. The power generation device 5 is connected to the charging management module and can also provide additional power supply methods such as bypass mains power and solar power.

[0039] The sound and light alarm component includes a sound alarm, a flashlight, a wireless communication module, an alarm controller, and a monitoring camera 7. The monitoring camera 7 is connected to a microcontroller, which controls the monitoring camera 7 to work in conjunction with the sound and light alarm component.

[0040] After the sound and light alarm component is triggered, the monitoring camera 7 captures external objects, the sound alarm sounds, the flashlight flashes at high frequency, and sends the image captured by the monitoring camera 7 and the information that the sound and light alarm component has been triggered to the monitoring backend.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
