Description

Technical Field

[0001] The invention relates to the technical field of highway isolation alarm devices and isolation monitoring, and in particular to a highway isolation fence dismantling prevention alarm device and an alarm method. Background Art

[0002] Highway fences, also known as highway guardrails, are an isolation device installed on the side of highways to prevent animals and people from entering the highways privately. They have the functions of protection and safety warning for highways, and can prevent people and animals from entering the highways by mistake and causing traffic accidents to a certain extent. Existing highway fences are mostly installed on one side of the highway by multiple fences, and then the different fences are fixed and connected side by side by welding or screws. In terms of daily inspection and maintenance, highway fences are mainly maintained by law enforcement and maintenance personnel on site walking or low-speed inspections, which to a certain extent requires more manpower and personnel energy for inspection. Due to the long distance of the highway, there are many fences deployed correspondingly, and the manual inspection method is relatively inefficient, especially when one or a few fences in the local area are opened or damaged, the inspectors often cannot promptly report to the monitoring center, so they are easily illegally invaded by other personnel. In addition, when a car accident occurs and the fence is knocked open, it is also impossible to promptly report to the police for processing, which is inconvenient.

[0003] At present, the literature discloses the deployment of cameras on both sides of the highway to assist in remote inspections, but the performance requirements of the cameras are high and the number is large, which means that the implementation and deployment of this solution requires a lot of capital costs. At the same time, for some areas with dense vegetation, the fence is often partially blocked, which will weaken the role of remote monitoring using cameras. Some other literature discloses the deployment of infrared monitoring devices on the fence to monitor people climbing over the fence, but for scenes where animals collide or other external forces shake the fence, causing the fence to shift or fall, the infrared monitoring method also has the problem of difficulty in timely sensing.

[0004] Therefore, in order to improve the efficiency of highway maintenance and inspection and save costs at the same time, how to provide a highway fence anti-dismantling alarm device that can timely warn and alarm the collapse, illegal dismantling or destruction of the fence in a convenient implementation to assist the highway maintenance department in carrying out maintenance work is a research topic of very positive and practical significance. Summary of the invention

[0005] In view of this, the purpose of the present invention is to propose a highway fence anti-dismantling alarm device and alarm method which has a simple structure, is easy to deploy, has good alarm feedback reliability, and can provide early warning feedback for fence fixation instability.

[0006] To achieve the above technical objectives, the technical solution adopted by the present invention is as follows:

The device includes a connecting wire, a housing, a controller, a power supply, a communication module and a wire break monitoring unit arranged in the housing. The controller is electrically connected to the power supply, the communication module and the wire break monitoring unit respectively. The connecting wire is connected to the wire break monitoring unit; the connecting wire spans at least one isolation fence and is attached or relatively fixed to the surface of the isolation fence; when the isolation fence undergoes relative displacement, the connecting wire is affected by the isolation fence and is stressed. When the connecting wire breaks, the wire break monitoring unit feeds back the wire break state of the connecting wire to the controller, so that the controller outputs an alarm message through the communication module.

[0008] As a possible implementation manner, further, the connecting wire in this solution is a connecting wire, which is connected to a signal source.

[0019] Wherein, the end of the connecting wire sequentially passes through the through hole, the inner ring of the annular structure of the slider and the avoidance hole, and then is connected to the wire break monitoring unit; the part of the connecting wire passing through the inner ring of the annular structure of the slider is fixedly connected to the slider through a fixing member; when the connecting wire is pulled by the force of detaching from the housing, it drives the slider to move or apply force in the direction close to the pressure sensor, and when the slider is in contact with the pressure sensor, the pressure sensor feeds back the sensed pressure to the controller.

[0020] Based on the above, this solution also provides a method for preventing the demolition and alarming of highway isolation fences, which applies a server and multiple above-mentioned highway isolation fence anti-demolition alarm devices; the server accesses the Internet, and multiple above-mentioned highway isolation fence anti-demolition alarm devices are fixedly arranged at intervals on different isolation fences, and they are all communicatively connected to an external communication base station through their own communication modules to access the server, and the server is also communicatively connected to a supervision background and / or a supervision terminal.

[0021] As a preferred example of implementation options, preferably, in the method of this solution, the connecting wire of the highway isolation fence anti-demolition alarm device is a connecting wire, which spans at least one isolation fence and is connected to a signal source, and the signal source transmits signals through the connecting wire, and the wire break monitoring unit receives the signals transmitted by the signal source through the connecting wire.

[0022] On the above basis, the alarm method described in this solution includes:

[0023] The signal source outputs a first signal in an active or passive manner through a connecting wire connected thereto at a preset time frequency;

[0024] The controller of the anti - tampering alarm device for highway isolation fences monitors the first signal transmitted through the connecting wire according to preset conditions through the disconnection monitoring unit. When a signal interruption occurs, the controller outputs an alarm message to the server through the communication module;

[0025] After receiving the alarm message, the server transmits it to the supervision background and / or supervision terminal connected to the server through communication.

[0026] As a preferred example of implementation, preferably, the anti - tampering alarm devices for highway isolation fences in this solution all have unique number information.

[0027] As an example, the alarm message in this solution is transmitted to the supervision background and / or supervision terminal in one or more of the ways of telephone, text message, and WeChat message; the alarm message is attached with the location information and / or number information of the anti - tampering alarm device for highway isolation fences that outputs the alarm message.

[0028] As a preferred example of implementation, preferably, in the method of this solution, the anti - tampering alarm device for highway isolation fences further includes a storage unit, and the controller also records the reception time of the first signal monitored in the storage unit to generate monitoring information.

[0029] As a preferred example of implementation, preferably, in the method of this solution, the controller also aggregates and records the component working parameters of the anti - tampering alarm device for highway isolation fences into a work log at a preset time frequency and stores it in the storage unit; the component working parameters include the power of the power supply.

[0030] As a preferred example of implementation, preferably, in the method of this solution, the controller also actively uploads the work log and monitoring information in the storage unit to the server at a preset time frequency, and the server stores the uploaded work log and monitoring information in groups according to the number information of the anti - tampering alarm device for highway isolation fences.

[0031] As a preferred example of implementation, preferably, in the method of this solution, when the supervision background and / or supervision terminal is communicatively connected to the server, it can retrieve the work log and monitoring information corresponding to the anti - tampering alarm device for highway isolation fences in the server.

[0032] As an example of a preferred implementation option, preferably, in the method of this solution, the connecting wire of the highway isolation fence anti-removal alarm device penetrates into the housing and is connected to the wire break monitoring unit provided in the housing. A through hole for penetrating the connecting wire is provided on the housing, and a force sensing component connected to the connecting wire is further provided on the housing. The force sensing component is electrically connected to the controller and is used to monitor the force condition of the connecting wire; on this basis, the alarm method of this solution further includes:

[0033] The controller obtains the force condition of the connecting wire in real time or at a preset time frequency through the force sensing component, and generates force monitoring information;

[0034] Determine the magnitude of the force on the connecting wire at different time points according to the force monitoring information, compare it with a preset force threshold, then record the duration or number of times that the force on the connecting wire is greater than the preset force threshold within a preset time period, and then generate and output an isolation fence early warning information according to preset conditions;

[0035] The isolation fence early warning information is attached with the position information and / or number information of the highway isolation fence anti-removal alarm device that outputs the isolation fence early warning information; it also includes isolation fence support instability information or isolation fence suspected damage information.

[0036] Adopting the above technical solution, compared with the prior art, the present invention has the following beneficial effects: This solution ingeniously sets an alarm device on the highway isolation fence. By deploying the connecting wire of the alarm device across the isolation fence, the connecting wire is pulled by the shaking of the isolation fence and breaks due to the force, so as to indirectly judge whether there is an abnormal situation of the isolation fence being disassembled or toppled. When the connecting wire uses a wire or other cables that can transmit signals, a signal can be input to it, and then the controller of the highway isolation fence monitors whether the signal is interrupted through the wire break monitoring unit to achieve an efficient and timely judgment of the disassembly and toppling states of the isolation fence; enabling the management personnel and patrol personnel in the background to timely learn about the abnormal situation of the isolation fence on the highway; on this basis, this solution also sets a force sensing component on the housing of the device, connects the force sensing component to the connecting wire to monitor the force state of the connecting wire, thereby judging whether the isolation fence shakes or is in other unstable states during a certain period, and generating relevant isolation fence early warning information accordingly, providing on-site inspection and maintenance tips for the background management personnel and patrol personnel, making the inspection work of the highway more targeted.

[0048] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be specifically noted that the following embodiments are only used to illustrate the present invention, but do not limit the scope of the present invention. Similarly, the following embodiments are only partial embodiments of the present invention rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0049] Combined with Figures 1 to 10 As shown in one of them, a highway isolation fence anti - tampering alarm device 200 in this embodiment is applied to the security of the isolation fence 100 on the highway. There are multiple isolation fences 100, which are installed on the side of the highway. The device includes a housing 210, a connecting wire 220, and a controller 230, a power supply 240, a communication module 231, and a wire break monitoring unit 250 arranged in the housing 210. The controller 230 is electrically connected to the power supply 240, the communication module 231, and the wire break monitoring unit 250 respectively, and the connecting wire 220 is connected to the wire break monitoring unit 250.

[0050] In this solution, multiple highway isolation fence anti - tampering alarm devices 200 can be deployed on different isolation fences 100, and then communicate with a base station near the highway (4G or 5G communication) to form an isolation fence anomaly monitoring system. By feeding back the monitoring situation to the background server, remote alarm supervision of the isolation fence 100 on the highway side can be realized. In this solution, the integrable unit modules such as the controller 230, the communication module 231, and the wire break monitoring unit 250 can be uniformly deployed on a circuit board 300 to achieve integration and improve the installation convenience.

[0051] In Figure 1 、 Figure 2 Or Figure 5 Based on the above - mentioned, combined with Figure 8 Or Figure 10 As shown, when the device in this solution is implemented, the connecting wire 220 straddles at least one isolation fence 100 and is attached to or relatively fixed to the surface of the isolation fence 100. When the isolation fence 100 undergoes relative displacement, the connecting wire 220 is affected by the isolation fence 100 and is stressed. When the connecting wire 220 breaks, the wire break monitoring unit 250 feeds back the wire break state of the connecting wire 220 to the controller 230, so that the controller 230 outputs an alarm message through the communication module 231.

[0052] In this solution, after establishing a communication connection with a base station near the highway, the communication module 231 can realize data interaction with the cloud platform 501 pre - deployed on the server to achieve efficient feedback of alarm information.

[0053] In this solution, the connection line 220 serves as a characteristic object for determining whether the isolation fence 100 has been removed, toppled, or other abnormal conditions. The connection line 220 can be made of conductive or light - guiding materials, that is, the main body of the connection line 220 is made of metal wires or light - guiding materials, and then an outer skin is coated. Since the connection line 220 spans multiple isolation fences 100 during wiring and is attached or relatively fixed to the surface of the isolation fence 100; when the isolation fence 100 undergoes relative displacement, the connection line 220 is affected by the isolation fence 100 and is stressed. By inputting a signal to the connection line 220 and then monitoring the interruption of the signal, it can indirectly determine whether the connection line 220 is broken, and then determine whether the corresponding isolation fence 100 has been removed or toppled (the "removed" state caused by human or non - human factors), so as to provide more timely and accurate information feedback for the inspection personnel and make the inspection and maintenance work more efficient.

[0054] In the solution of this embodiment, taking the connection wire as the material of the connection line 220 as an example, the signal source for inputting a signal to it can be an internal signal source or an external signal source.

[0055] Combined with Figure 4 、 Figure 5 As shown, as an example of a possible implementation method of the external signal source 400, further, the connection line 220 in this solution is a connection wire, which is connected to a signal source, and the signal source is an external signal source 400. The signal source transmits signals through the connection line 220, and the disconnection monitoring unit 250 receives the signals transmitted by the signal source through the connection line 220. Among them, the disconnection monitoring unit 250 includes a signal receiving module 251. After receiving the signal transmitted by the connection line 220 through the signal receiving module 251, it feeds it back to the controller 230 to achieve the monitoring of whether the signal is interrupted. The external signal source 400 can be a signal transmitting device independently deployed in a preset area of the highway, which transmits signals to multiple highway isolation fence anti - removal alarm devices 200 through the connection line 220 to achieve abnormal early warning of the isolation fences 100 in different areas.

[0056] Combined with Figure 2 、 Figure 5 As shown, as an example of the implementation option where the signal source is an internal signal source, preferably, the disconnection monitoring unit 250 in this solution includes a signal receiving module 251 and a signal transmitting module 252. Among them, the signal transmitting module 252 is set as the signal source, and the signal receiving module 251 and the signal transmitting module 252 can be connected to the same connection line respectively, or to different connection lines.

[0057] Among them, combined with Figure 7 、Figure 8 As shown, it shows an example of the deployment state when the signal receiving module 251 and the signal transmitting module 252 can be respectively connected to the same connection line 220. The connection line 220 can be deployed across multiple isolation fences 100 in a looped manner. The signal transmitting module 252 is controlled by the controller 230 to emit signals at a preset time frequency or in real time, and then the signal receiving module 251 receives the signals and forms a transceiver record. When there is only a signal transmission record but no corresponding reception record in the transceiver record, it can be determined that the connection line 220 is interrupted, and then it can be indirectly determined that the isolation fence 100 has been removed, and an alarm message is output accordingly.

[0058] Combined with Figure 9 、 Figure 10 As shown, in this solution, when the signal source is built-in, during implementation, multiple highway isolation fence anti-removal alarm devices 200 can also be deployed at intervals on multiple isolation fences of the highway, and then the connection lines 220 of adjacent highway isolation fence anti-removal alarm devices 200 are connected in sequence. The status monitoring of the isolation fence 100 is realized by gradually sending signals through adjacent highway isolation fence anti-removal alarm devices 200. For example, the controller 230 of the previous highway isolation fence anti-removal alarm device 200 controls the signal transmitting module 252 to emit signals at a preset time frequency or in real time, and then the signal receiving module 251 of the disconnection monitoring unit 250 of the next highway isolation fence anti-removal alarm device 200 receives the signals and forms a reception record. When the time since the last reception recorded in the reception record exceeds a preset duration and there is no corresponding reception record anymore, it can be determined that the connection line 220 is interrupted, and then it can be indirectly determined whether the isolation fence 100 between the adjacent highway isolation fence anti-removal alarm devices 200 has been removed, and an alarm message is output accordingly.

[0059] Combined with Figure 1 、 Figure 2 、 Figure 3 、 Figure 8 Or Figure 10As shown in one of the figures, in this solution, since the connecting wire 220 spans multiple isolation fences 100, especially across the middle or upper part of the isolation fence 100, after the isolation fence 100 is installed, it may undergo a certain small swing due to wind blowing or land vibration, which is a relatively common working condition. To prevent the common small swing condition from causing the connecting wire 220 to break and thus making the highway isolation fence anti - tampering alarm device 200 give false alarms, as a preferred example of implementation, preferably, an elastic buffer section 221 is provided on the connecting wire 220 of this solution. The connecting wire 220 at the elastic buffer section 221 has a first state and a second state. In the first state, the connecting wire 220 is in a non - straight state under the traction force less than the first acting force; in the second state, the connecting wire 220 is in a straight state under the traction force greater than or equal to the first acting force. That is, in this solution, a non - straight connecting wire 220 can be formed as the elastic buffer section 221, so that when the isolation fence 100 undergoes a small movement, the elastic buffer section 221 of the connecting wire 220 can stretch to adapt, avoiding directly breaking the connecting wire 220. Among them, an external auxiliary elastic part can be added, or the outer skin of the connecting wire 220 of the elastic buffer section 221 can be made of an elastic coating material and then curled to form a relatively stable bent section in the unloaded state.

[0060] Focusing on Figure 3 , to prevent the connecting wire 220 of the elastic buffer section 221 from losing its elastic recovery ability too quickly after long - term use, as a preferred example of implementation, preferably, a spring 222 (external auxiliary elastic part) is sleeved on the elastic buffer section 221 of the connecting wire of this solution. The two ends of the spring 222 are connecting sections 2221, which are respectively fixedly connected to the connecting wire 220 at both ends of the elastic buffer section 221 through straps 223 (or other fixing parts). In this case, after the connecting wire 220 of the elastic buffer section 221 is stretched, the elastic recovery of the spring 222 can be used to assist in resetting.

[0061] In this solution, indirectly judging the "being removed" situation of the isolation fence 100 through the signal on - off condition of the connecting wire 220 can obtain better monitoring feedback at the result level, but it has limitations for some situations during the occurrence process. For example, when the isolation fence 100 is blown by animals or wind and its fixation to the ground becomes unstable and shakes, it is difficult to judge through the signal on - off of the connecting wire 220.

[0062] To facilitate the recording of monitoring information, as a preferred example of implementation, preferably, this device of this solution further includes a storage unit 260, and the storage unit 260 is used to store the monitoring information received and recorded by the controller 230; among them, the controller 230 also outputs the monitoring information through the communication module 231.

[0063] Focusing on Figure 2 、 Figure 4 、 Figure 6 、 Figure 8 、 Figure 10 As shown in, based on the unstable situation of the isolation fence 100, as a preferred implementation option example, preferably, the connecting line 220 in this solution penetrates into the housing 210 and is connected to the disconnection monitoring unit 250 provided in the housing 210. A through hole 211 for penetrating the connecting line 220 is provided on the housing 210. A force sensing component 270 connected to the connecting line 220 is also provided on the housing 210. The force sensing component 270 is electrically connected to the controller 230 and is used to monitor the force condition of the connecting line 220.

[0064] As a preferred implementation option example of the force sensing component 270, preferably, the force sensing component 270 in this solution includes:

[0065] A connecting sleeve 271, which is a circular tubular structure. One end of it is fixed in the inner wall area of the housing 210 where the through hole 211 is provided. The virtual axis of the connecting sleeve 271 passes through the through hole 211;

[0066] A slider 272, which is an annular structure. Its outer contour is adapted to the inner wall of the circular tubular structure of the connecting sleeve 271;

[0067] A connecting cover 273, which covers the other end of the connecting sleeve 271, and a relief hole 2731 is provided in the middle thereof;

[0068] A pressure sensor 280, which is fixedly arranged on the inner wall of the housing 210 on one side of the through hole 211 and is located inside the connecting sleeve 271. The pressure sensor 280 is electrically connected to the controller 230.

[0069] Among them, the end of the connection line 220 sequentially passes through the through hole 211, the inner ring 2721 of the annular structure of the slider 272, and the avoidance hole 2731, and then is connected to the disconnection monitoring unit 250; the part of the connection line 220 passing through the inner ring 2721 of the annular structure of the slider 272 is fixedly connected to the slider 272 through a fixing member 2722 (such as a clamp or an adhesive block); in this implementation form, when the connection line 220 is pulled by the force of detaching from the housing, it drives the slider 272 to move or apply force in the direction approaching the pressure sensor 280. When the slider 272 is in contact with the pressure sensor 280, the pressure sensor 280 feeds back the sensed pressure to the controller 230, so as to realize the monitoring of the tensile condition of the connection line 220; and by monitoring the tensile condition of the connection line 220, it is possible to realize the monitoring of whether the isolation fence 100 shakes due to unstable installation or being pushed by external objects such as animals or people, so as to provide more timely maintenance warning feedback for the patrol personnel.

[0070] Based on the above content and Figures 1 to 10 one of the schematic bases, focusing on combining Figure 4 or Figure 6 As shown, this solution also provides a method for preventing the removal and alarming of highway isolation fences, which applies multiple highway isolation fence anti-removal alarm devices 200 as described above, and also applies a server (on which a cloud platform 501 is deployed); the server accesses the Internet to realize the networking of the cloud platform 501. Multiple highway isolation fence anti-removal alarm devices 200 are fixedly arranged at intervals on different isolation fences 100, and they are all communicatively connected to an external communication base station 500 through their own communication modules 231 to access the server. The server is also communicatively connected to a supervision background 600 and / or a supervision terminal 700 to realize data interaction between the cloud platform 501 and the supervision background 600 and / or the supervision terminal 700.

[0071] In this solution, the supervision background 600 can be a PC or other background devices, and the supervision terminal 700 can be a mobile electronic device such as a mobile phone or a PAD. The supervision background 600 also establishes communication interaction with the supervision terminal 700 to realize data mutual transmission.

[0072] In the method of this solution, the connection line 220 of the highway isolation fence anti-removal alarm device 200 is a connecting wire, which spans at least one isolation fence 100 and is connected to a signal source (which can be external or internal). The signal source transmits signals through the connection line 220, and the disconnection monitoring unit 250 receives the signals transmitted by the signal source through the connection line 220.

[0073] Combined with Figures 1 to 10 one of them, on the above hardware basis, the alarm method of this solution includes:

[0074] The signal source outputs a first signal at a preset time frequency in an active or passive manner through the connecting line 220 connected thereto.

[0075] The controller 230 of the highway isolation fence anti-tampering alarm device 200 monitors the first signal transmitted by the connecting line 220 through the disconnection monitoring unit 250 according to preset conditions. When a signal interruption occurs, the controller 230 outputs an alarm message to the server through the communication module 231 and then inputs it into the cloud platform 501.

[0076] After receiving the alarm message, the server (cloud platform 501) transmits it to the supervision background 600 and / or the supervision terminal 700 that are communicatively connected to the server.

[0077] Among them, for the convenience of data collection and retrieval, as a preferred example of an implementation option, preferably, the highway isolation fence anti-tampering alarm device 200 of this solution all has unique identification information.
