[0037] Considering that existing road studs, as warning road studs for protecting power cables, are prone to being damaged and losing their warning function, they need to be inspected regularly. However, in daily maintenance inspections, it is generally carried out manually, which is time-consuming and laborious, and the inspection cost is relatively high. This application provides a cable anti-external damage system and a cable anti-external damage system inspection method, which not only do not require manual inspection, but also have a good inspection effect, effectively reducing the inspection cost and being convenient for application and promotion.

[0038] Specifically, please refer to the appendix Figures 1 to 3, an embodiment of the present application provides a cable anti-external damage system, which may include a spike 10, a master control terminal 20 and a patrol device 30. The spike 10 includes a first circuit board 100 and an alarm device 200 which are electrically connected. The first circuit board 100 is electrically connected to a vibration sensor 110 and a communication control unit 120. The vibration sensor 110 is used to collect abnormal vibration signals and transmit them to the communication control unit 120. The master control terminal 20 is communicatively connected to the communication control unit 120. The communication control unit 120 is used to feedback an abnormal alarm signal to the master control terminal 20 after receiving the abnormal vibration signal. The patrol device 30 is used to move near the spike 10 and emit a simulated vibration signal. The communication control unit 120 can receive the simulated vibration signal and feedback an abnormal alarm signal to the patrol device 30 and / or the master control terminal 20. The alarm device 200 is used to emit an alarm when the communication control unit 120 receives the abnormal vibration signal and / or the simulated vibration signal.

[0039] When the above cable anti-external damage system is patrolled, by setting that the patrol device 30 emits a simulated vibration signal, and the communication control unit 120 of the spike 10 can receive the aforementioned simulated vibration signal and feedback an abnormal alarm signal to the patrol device 30 and / or the master control terminal 20, the function simulation of the spike 10 is realized. Then, the staff only needs to monitor whether the patrol device 30 and / or the master control terminal 20 can receive the abnormal alarm signal to complete the inspection of whether the function of the spike 10 is normal, avoiding manual patrol, effectively improving the patrol efficiency and reducing the patrol cost.

[0040] Understandably, as shown in Figure 1 The above patrol device 30 can also be communicatively connected to the master control terminal 20. After the spike 10 feeds back the abnormal alarm signal to the patrol device 30, the patrol device 30 can send the abnormal alarm signal to the master control terminal 20. Then, the staff only needs to remotely monitor the master control terminal 20 to realize the inspection of whether the function of the spike 10 is normal. In this way, the patrol efficiency can be effectively improved and the patrol cost can be reduced.

[0041] Specifically, the above vibration sensor 110 is used to collect abnormal vibration signals, and the abnormal vibration signals can be vibration signals within a specific frequency range. Considering the situation of false alarms or missed alarms, the vibration sensor selected can have a vibration frequency range of 12.5HZ - 6.66KHZ or other suitable ranges.

[0042] Exemplarily, on a cement road surface, the vibration threshold of the abnormal vibration signal can be set to be greater than or equal to 2000 hertz and the duration is greater than or equal to 5 seconds. On an asphalt road surface, the vibration threshold of the abnormal vibration signal can be set to be greater than or equal to 2000 hertz and the duration is greater than or equal to 5 seconds.

[0043] When the aforementioned vibration sensor 110 collects an abnormal vibration signal, the communication control unit 120 simultaneously sends an abnormal alarm signal to the inspection device 30 and / or the master control terminal 20. After the staff receives the abnormal alarm signal at the inspection device 30 and / or the master control terminal 20, corresponding measures can be taken immediately, such as dispatching personnel to investigate the site, thereby realizing the protection of the power cable. In addition, the cable external damage prevention system of the present application is also provided with an alarm device 200, which can actively issue an alarm in the case of abnormal vibration, thereby improving the active warning property of the cable external damage prevention system.

[0044] Optionally, the communication control unit 120 can be used for wireless transmission of communication signals, and can but is not limited to adopting low-power communication methods such as NB-IoT (Narrow Band Internet of Things), CAT-1 (LTE UE-Category 1), etc.; or, in combination with the on-site signal conditions, adopting communication methods such as LTE Cat.4 (LTE UE-Category.4), LoRa / WAN (Low Power Wide Area Network), etc.

[0045] In addition, the above cable external damage prevention system is also provided with an inspection device 30, which can but is not limited to be implemented as an inspection vehicle or a drone, etc.

[0046] Preferably, the inspection device 30 can be implemented as a drone, which can improve the inspection efficiency. When the cable external damage prevention system needs to conduct an inspection, the drone can fly along a preset cruise route and send an analog vibration signal to the communication control unit 120 of the spike 10 at a preset location. When the communication control unit 120 can receive and send an abnormal alarm signal to the drone and / or the master control terminal 20, it means that the spike 10 is in a normal functional state. If the drone and / or the master control terminal 20 cannot receive the aforementioned abnormal alarm signal, it means that the spike 10 is in a state of suspected function and needs to be inspected or repaired. In this way, rapid inspection and maintenance of the spike 10 can be realized, reducing the manpower and time costs of inspection and improving the inspection efficiency.

[0047] Optionally, the spike 10 can be provided with an identification label for the inspection device 30 to identify information, and the inspection device 30 can send the identified information to the master control terminal 20. In this way, when a spike 10 with a suspected function is found during the inspection, the inspection device 30, such as a drone, can move to the identification label and actively identify the information. Then, the staff can directly locate to the individual spike 10 with a suspected function at the master control terminal 20, improving the inspection efficiency. Specifically, the aforementioned identified information can be the model, label or serial number of the spike 10, etc.

[0048] Optionally, continue to refer to Figure 2, the road stud 10 may include a placement box 300, an inner housing 500, and an outer housing 600. The first circuit board 100 and the alarm device 200 are arranged inside the placement box 300. The placement box 300 is arranged inside the inner housing 500, and the outer housing 600 covers the inner housing 500, thus improving the structural protection of the road stud 10.

[0049] Specifically, between the aforementioned inner housing 500 and the placement box 300, and between the inner housing 500 and the outer housing 600, they can be installed in forms such as but not limited to threaded connection or snap connection.

[0050] Optionally, the outer housing 600 can be set to be transparent, thus improving the alarm effect of the alarm device 200. For example, when the alarm device 200 is implemented as a light emitter, it can improve the light emission effect of the light emitter. Additionally, in this embodiment, by setting the placement box 300 for installing the first circuit board 100 and the alarm device 200, it helps to improve the maintainability of the first circuit board 100 and the alarm device 200. During maintenance, only need to first disassemble the outer housing 600, and then directly disassemble the placement box 300 from the inner housing 500.

[0051] Optionally, as shown in Figure 5 The outer housing 600 can also be provided with wear-resistant bumps 610, thus improving the wear resistance of the outer housing 600 as the outermost protective shell of the road stud 10. In some other embodiments, the outer housing 600 can also be provided with at least 2 reinforcing ribs (not shown), thus further increasing the structural strength of the outer housing 600.

[0052] Optionally, as shown in Figure 2 The inner housing 500 can be provided with a sealing ring 510 along its outer circumferential direction. The sealing ring 510 is used to be squeezed and arranged between the outer housing 600 and the inner housing 500, thus helping to improve the sealing performance of the road stud 10, preventing the structures inside the placement box 300 from getting waterlogged, and improving the protection of the road stud 10.

[0053] Preferably, there can be at least 2 of the aforementioned sealing rings 510. For example, the sealing ring 510 can be provided with 2, 3, or 4.

[0054] Optionally, as shown in Figure 3 The first circuit board 100 can be electrically connected to a temperature and humidity sensor 150. The temperature and humidity sensor 150 is used to send temperature and humidity information to the master control terminal 20 through the communication control unit 120. In this way, the staff can judge the waterlogging state of the road stud 10 according to the temperature and humidity information and take corresponding maintenance measures.

[0055] Specifically, the temperature and humidity sensor 150 can monitor the temperature and humidity inside the spike 10 in real time. The temperature and humidity sensor 150 can be provided with alarm thresholds for temperature and humidity. When the temperature and humidity exceed the alarm thresholds, the temperature and humidity sensor 150 can send an alarm signal of equipment wading to the master control terminal 20 through the communication control unit 120, which helps to improve the protection of the spike 10.

[0056] Optionally, as shown in Figure 4 The inner housing 500 is further provided with a handle 520 for grasping the inner housing 500 during assembly with other structures such as the placement box 300, the outer housing 600, etc., which can improve the assembly simplicity.

The alarm device 200 is limited on the placement plate 400 through the second positioning mechanism 420, which can achieve the rapid installation of the first circuit board 100 and the alarm device 200.

[0060] Specifically, the aforementioned first positioning mechanism 310 and the second positioning mechanism 420 can be, but are not limited to, implemented as positioning posts. The first circuit board 100 and the alarm device 200 are correspondingly provided with positioning holes. The first circuit board 100 and the alarm device 200 are installed in a limited manner in the placement box 300 by matching the positioning holes with the positioning posts.

[0061] Optionally, the aforementioned alarm device 200 can be, but is not limited to, implemented as a sound alarm or a light emitter, etc. It should be noted that the traditional passive warning method relying only on surface coating and letter printing has poor warning performance, especially the visibility is greatly reduced in weather such as at night or in fog. By providing the alarm device 200 in this application, the warning effect can be improved, achieving active warning. Even in weather such as at night or in fog, its visibility or perceptibility can be greatly improved, achieving effective warning.

[0062] Optionally, referring to Figure 3 , the alarm device 200 may include an integration board 210, a light-emitting member 220, and a warning member 230. The light-emitting member 220 and the warning member 230 are disposed on the integration board 210.

Specifically, the foregoing warning member 230 may be, but is not limited to, implemented as a warning arrow or a structural member engraved with a warning message. Additionally, in this embodiment, both the light-emitting member 220 and the warning member 230 are disposed on the integration board 210, and the integration board 210 abuts against the second positioning mechanism 420, which helps to improve the structural integrity of the alarm device 200.

[0066] Optionally, the first circuit board 100 may be electrically connected to a positioning unit 130, and the positioning unit 130 is configured to send positioning information to the master control terminal 20 through the communication control unit 120. It can be understood that the positioning unit 130 may send positioning information to the master control terminal 20 simultaneously when the vibration sensor 110 receives an abnormal vibration signal, which helps to improve the intelligence of the cable anti-external damage system and avoid problems such as the inability to locate spikes in the traditional method and the need for manual reporting only after the spikes are damaged. The problem of inability to locate in the traditional method will further lead to difficulties in finding the damage point and slow repair progress, resulting in an increase in economic losses.

[0067] According to the above embodiment of the present application, by providing that the first circuit board 100 is electrically connected to a positioning unit 130, and the positioning unit 130 is configured to send positioning information to the master control terminal 20 through the communication control unit 120, it enables the staff to quickly locate the abnormal vibration location and take protective measures, realizing the protection of the power cable.

[0068] Specifically, the positioning unit 130 can be, but is not limited to, implemented as a Beidou positioning chip, which can include a chipset of an RF radio frequency chip, a baseband chip, and a microprocessor. The Beidou positioning chip can receive signals transmitted by Beidou satellites, thereby completing the functions of positioning and navigation, outputting position information, and providing the accurate position of the spike 10 to the master control terminal 20. In addition, the cable anti-external damage system of the present application can accurately reflect the position of abnormal vibration to the master control terminal 20 by combining with the Beidou positioning system and actively upload data.

Both the second circuit board 1000 and the first circuit board 100 are electrically connected to the solar panel 900, so that power supply to the second circuit board 1000 and the first circuit board 100 can be achieved.

[0076] In addition, the solar panel 900 can also be used as a light-sensing device for sensing the light conditions of the environment. The solar panel 900 can be electrically connected to the control center 140. By transmitting the light-sensing signal to the control center 140, the control center 140 can judge the on-site light conditions according to the light-sensing signal, and then the control center 140 can actively control the light-emitting component 220 to emit light or flash under poor environmental light or other abnormal conditions.

If the inspection device 30 and / or the master control terminal 20 receive the abnormal alarm signal fed back by the communication control unit 120 of the spike 10, the inspection device 30 proceeds to the next inspection fixed point. If the inspection device 30 and / or the master control terminal 20 do not receive the abnormal alarm signal fed back by the communication control unit 120 of the spike 10, the inspection device 30 and / or the master control terminal 20 record the abnormal spike 10.

[0081] In the above cable external damage prevention system inspection method, by sending a simulated vibration signal by the inspection device 30, the communication control unit 120 of the spike 10 can receive the aforementioned simulated vibration signal and feedback an abnormal alarm signal to the inspection device 30 and / or the master control terminal 20. The function simulation of the spike 10 is realized. Then, the staff only needs to monitor whether the inspection device 30 and / or the master control terminal 20 can receive the abnormal alarm signal to complete the inspection of whether the function of the spike 10 is normal, avoiding manual inspection, effectively improving the inspection efficiency and reducing the inspection cost.

[0082] Preferably, in some embodiments, in step S1, emitting the analog vibration signal at the preset point can be set as: emitting the analog vibration signal twice at the preset point. In this way, a secondary judgment can be made to improve the fault tolerance rate of the inspection tour. If neither the inspection device 30 nor the master control terminal 20 receives the abnormal alarm signal feedback from the spike 10 during the secondary signal emission of the inspection device 30, it indicates that the function of the spike 10 is questionable and needs to be repaired, and the inspection device 30 and / or the master control terminal 20 will record the abnormal spike 10.

[0083] Optionally, the cable anti-external damage system inspection method may further include the step of setting an inspection cycle, and the inspection cycle is 7 days to 15 days.

[0084] Optionally, the inspection device 30 can set the automatic inspection time and inspection route according to the above inspection cycle to realize the automatic inspection of the inspection device 30. In this way, it helps to improve the inspection efficiency and reduce the inspection cost.

[0085] In addition, in some embodiments, the inspection device 30 is also provided with a camera. In this way, the camera can be used to perform high-definition imaging of the inspection location to improve the on-site monitoring effect of the power cable. Understandably, the inspection device 30 can also be used as an active device for on-site inspection. The staff can achieve active monitoring at any time on the site through the active control of the inspection device 30. In this way, the frequency of the staff arriving at the site can be reduced, and the cost of on-site monitoring can be reduced.
