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

Specific implementation manners

[0027] The following combines the accompanying drawings and embodiments to make a further detailed description of the present invention. It should be particularly 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.

[0028] Combined with Figures 1 to 10As shown in one of them, in this embodiment, a highway isolation fence anti - demolition alarm device 200 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 connection line 220, a controller 230, a power supply 240, a communication module 231 and a disconnection 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 disconnection monitoring unit 250 respectively, and the connection line 220 is connected to the disconnection monitoring unit 250.

[0029] In this solution, multiple highway isolation fence anti - demolition 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 controller 230, the communication module 231, the disconnection monitoring unit 250 and other integrable unit modules can be uniformly deployed on a circuit board 300 to achieve integration and improve the installation convenience.

[0030] In Figure 1 、 Figure 2 or Figure 5 shown on the basis of, combined with Figure 8 or Figure 10 shown, when the device of this solution is implemented, the connection line 220 straddles at least one isolation fence 100, 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. When the connection line 220 is disconnected, the disconnection monitoring unit 250 feeds back the disconnection state of the connection line 220 to the controller 230, so that the controller 230 outputs alarm information through the communication module 231.

[0031] 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.

[0032] In this solution, the connection line 220 is a characteristic object used to determine 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 be indirectly determined whether the connection line 220 has broken, and then it can be determined whether the isolation fence 100 at the corresponding position 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.

[0033] 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.

[0034] Combined with Figure 4 、 Figure 5 As shown, as an example of a possible implementation manner 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 monitor 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 - theft alarm devices 200 through the connection line 220 to realize abnormal early warning of the isolation fences 100 in different areas.

[0035] 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 can be connected to different connection lines.

[0036] Among them, combined with Figure 7 、 Figure 8As 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 send signals at a preset time frequency or in real time, and then the signal receiving module 251 receives 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, thereby outputting an alarm message.

[0037] 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 achieved 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 send 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 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, 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, thereby outputting an alarm message.

[0038] Combined with Figure 1 、 Figure 2 、 Figure 3 、 Figure 8 Or Figure 10As shown in one of them, in this solution, since the connecting line 220 straddles multiple isolation fences 100, especially the middle or upper part of the isolation fence 100, after the isolation fence 100 is installed, it may swing slightly due to wind or land vibration, which is a relatively common working condition. To avoid the connecting line 220 breaking due to this common small swing condition, thus causing the highway isolation fence anti-theft alarm device 200 to give a false alarm. As a preferred example of an implementation option, preferably, an elastic buffer section 221 is provided on the connecting line 220 of this solution. The connecting line 220 located at the elastic buffer section 221 has a first state and a second state. In the first state, the connecting line 220 is in a non-straight state under the traction force less than the first acting force; in the second state, the connecting line 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 line 220 can be formed as the elastic buffer section 221, so that when the isolation fence 100 is slightly pulled, the elastic buffer section 221 of the connecting line 220 can stretch to adapt, avoiding directly breaking the connecting line 220. Among them, an external auxiliary elastic member can be added, or the outer skin of the connecting line 220 of the elastic buffer section 221 can be made of an elastic coating material, and then it is curled to form a relatively stable bent section in the non-loaded state.

[0039] Focusing on Figure 3 , to avoid the connecting line 220 of the elastic buffer section 221 losing its elastic recovery ability too quickly after long-term use. As a preferred example of an implementation option, preferably, a spring 222 (external auxiliary elastic member) is sleeved on the elastic buffer section 221 of the connecting line of this solution. The two ends of the spring 222 are connecting sections 2221, which are respectively fixedly connected to the connecting line 220 at both ends of the elastic buffer section 221 through straps 223 (or other fixing members). In this case, after the connecting line 220 of the elastic buffer section 221 is stretched, the elastic recovery of the spring 222 can be used to assist in resetting.

[0040] In this solution, indirectly judging the "being removed" situation of the isolation fence 100 through the signal on / off situation of the connecting line 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 line 220.

[0041] To facilitate the recording of monitoring information. As a preferred example of an implementation option, preferably, the 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.

[0042] Focusing on combining Figure 2 , Figure 4 , Figure 6 , Figure 8 , Figure 10 As shown in the figures, based on the situation where the isolation fence 100 becomes unstable, as a preferred example of an implementation option, preferably, the connecting line 220 in this solution penetrates into the housing 210 and is connected to the broken wire 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 assembly 270 connected to the connecting line 220 is further provided on the housing 210. The force sensing assembly 270 is electrically connected to the controller 230 and is used to monitor the force condition of the connecting line 220.

[0043] As a preferred example of an implementation option of the force sensing assembly 270, preferably, the force sensing assembly 270 in this solution includes: 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; 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; A connecting cover 273, which covers the other end of the connecting sleeve 271. A relief hole 2731 is provided in the middle of it; 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.

[0044] Among them, the end of the connecting line 220 passes through the through hole 211, the inner ring 2721 of the annular structure of the slider 272 and the relief hole 2731 in sequence and then is connected to the broken wire monitoring unit 250; the part of the connecting 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 connecting line 220 is driven by the force of breaking away 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 connecting line 220; and by monitoring the tensile condition of the connecting line 220, it is possible to monitor 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 inspection personnel.

[0045] Based on the above content and Figures 1 to 10 one of the schematic bases, with a focus on combining Figure 4 or Figure 6 As shown, this solution also provides a method for anti - removal alarm of highway isolation fences. It applies multiple anti - removal alarm devices 200 for highway isolation fences 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 anti - removal alarm devices 200 for highway isolation fences 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 be connected to 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.

[0046] 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.

[0047] In the method of this solution, the connection line 220 of the anti - removal alarm device 200 for highway isolation fences 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.

[0048] Combined with Figures 1 to 10 one of them, based on the above - mentioned hardware, the alarm method of this solution includes: The signal source outputs a first signal through the connection line 220 connected to it in an active or passive manner according to a preset time frequency; The controller 230 of the anti - removal alarm device 200 for highway isolation fences monitors the first signal transmitted by the connection line 220 through the disconnection monitoring unit 250 according to a preset condition. 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; After receiving the alarm message, the server (cloud platform 501) transmits it to the supervision background 600 and / or the supervision terminal 700 communicatively connected to the server.

[0049] Among them, in order to facilitate data collection and retrieval, as a preferred example of implementation, preferably, each anti - removal alarm device 200 for highway isolation fences in this solution has a unique identification information.

[0050] As an example, the alarm information described in this solution can be transmitted to the supervision background 600 and / or the supervision terminal 700 in one or more ways such as telephone, text message, and WeChat message; the alarm information is attached with the position information and / or number information of the highway isolation fence anti-removal alarm device 200 that outputs the alarm information. After the highway isolation fence anti-removal alarm device 200 is deployed, relevant information can be manually input, or a position sensor can be further set on the highway isolation fence anti-removal alarm device 200, and then the position information can be fed back after it is powered on and working.

[0051] In this solution, in order to improve the power consumption and endurance ability of the highway isolation fence anti-removal alarm device 200, a solar panel assembly can also be further installed on its shell 210 and connected to the controller 230 and the power supply 240 to achieve an improvement in power supply and endurance; it can also be connected to an external power supply device through the power supply 240, or when the power supply is an internal power supply, the shell 210 can be set into a structure that can facilitate the disassembly and replacement of the power supply to facilitate the replacement of the internal power supply.

[0052] For the convenience of data recording, as a preferred example of an implementation option, preferably, in the method of this solution, the highway isolation fence anti-removal alarm device 200 further includes a storage unit 260, and the controller 230 also records the reception time of the first signal monitored in the storage unit 260 to generate monitoring information.

[0053] For the convenience of maintenance, as a preferred example of an implementation option, preferably, in the method of this solution, the controller 230 can also collect and record the component working parameters (such as the power supply 240, the pressure sensor 280, etc.) of the highway isolation fence anti-removal alarm device 200 into a work log at a preset time frequency and store it in the storage unit 260; the component working parameters include the power of the power supply 240.

[0054] Correspondingly, as a preferred example of an implementation option, preferably, in the method of this solution, the controller 230 also actively uploads the work log and monitoring information in the storage unit 260 to the server at a preset time frequency, and the cloud platform 501 deployed in the server stores the relevant information. The cloud platform 501 of the server stores the uploaded work log and monitoring information in groups according to the number information of the highway isolation fence anti-removal alarm device 200.

[0055] When the number of deployed highway isolation fence anti-removal alarm devices 200 is large, for the convenience of targeted information query and retrieval, as a preferred example of implementation options, preferably, in the method of this solution, when the supervision background 600 and / or the supervision terminal 700 are communicatively connected to the server (cloud platform 501), they can retrieve the working logs and monitoring information corresponding to the highway isolation fence anti-removal alarm devices 200 in the server (cloud platform 501).

[0056] In terms of the force monitoring of the connection line 220, as a preferred example of implementation options, preferably, in the method of this solution, the connection line 220 of the highway isolation fence anti-removal alarm device 200 penetrates into the housing 210 and is connected to the disconnection monitoring unit 250 provided in the housing 210. The housing 210 is provided with a through hole 211 for penetrating the connection line (a waterproof sleeve 212 can be further provided on the through hole 211). The housing 210 is also provided with a force sensing assembly 270 connected to the connection line 220. The force sensing assembly 270 is electrically connected to the controller 230 and is used to monitor the force condition of the connection line 220. On this basis, the alarm method of this solution further includes: The controller 230 obtains the force condition of the connection line 220 in real time or at a preset time frequency through the force sensing assembly 270 to generate force monitoring information; Determine the magnitude of the force on the connection line 220 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 when the force on the connection line 220 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; 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 200 that outputs the isolation fence early warning information; it also includes the isolation fence 100 support instability information or the isolation fence 100 suspected damage information.

[0057] Among them, as an example, when the force monitoring information indicates that the force on the connecting line 220 exceeds the preset force threshold (less than the breaking force of the connecting line 220) for a duration or number of times exceeding the set value within a certain time period, it can be preliminarily determined that the isolation fence 100 is shaking. Therefore, an isolation fence warning message can be generated and output according to the preset conditions. The background management personnel can further query the meteorological conditions of the highway area where the highway isolation fence anti-theft alarm device 200 is located through this warning message. If there is strong wind or rain during this time period, it can be preliminarily determined that the shaking of the isolation fence 100 is caused by weather factors. If the weather is clear and there is no strong wind, it can be preliminarily determined that there may be animal or human shaking. Then, based on this, relevant inspection arrangement plans can be formulated to make the safety anti-theft monitoring of the isolation fence 100 more targeted.

[0058] This solution has the following positive significance in the inspection of highway isolation fences: 1. Solve the problem of occupying human and material resources for inspections.
