Description

Technical Field

[0001] The utility model belongs to the technical field of underground cable monitoring, and particularly relates to an underground cable anti-damage monitoring system based on the Beidou system and intelligent ground nails. Background Technique

[0002] During the process of electric energy transmission, the safe and stable operation of transmission lines is the key to ensuring the reliable supply of electric energy. Traditional overhead lines have the characteristics of low cost and easy repair, but they will occupy urban land, obstruct traffic, affect the urban image, and are vulnerable to extreme weather. Therefore, each city in China has begun to vigorously promote the construction of underground cables, and the laying rate of underground cables has increased year by year. However, with the rapid development of China's economy, the number of infrastructure construction projects across the country has increased significantly, and the incidents of underground cable damage occur frequently, which not only cause great economic losses, but also seriously affect the reliability of power supply.

[0003] In order to prevent underground cables from being damaged by external forces, the main measures currently taken are to set up warning signs, conduct regular inspections by inspection personnel, and add protective outer pipes when laying cables. However, there are still many problems. Among them, setting up warning signs belongs to a passive protection method. If construction personnel ignore the reminder and insist on construction, the underground cables may still be damaged. In addition, over time, the warning signs may be lost, so that they cannot effectively protect the nearby underground cables from being damaged; regular inspections require a large amount of manpower and material resources, are easily affected by environmental factors and the quality of inspection personnel themselves, are inefficient, and cannot maintain the normal operation of the cables. At the same time, since the cables are buried underground in the city, the inspection personnel cannot understand the operation status of the cables in real time, cannot give timely feedback when problems occur, and cannot locate and repair in time in case of large-scale power outages or information interruptions, resulting in unnecessary economic losses; adding a protective outer sleeve around the cables increases their ability to resist external force damage, but at the same time, it also invisibly increases the manufacturing cost. Once encountering large construction machinery, the protective effect becomes very limited. Therefore, the prior art cannot realize real-time and accurate monitoring of cable external damage behavior and cannot effectively respond to emergencies. Content of the Utility Model

[0004] The purpose of the utility model is to provide an underground cable anti-damage monitoring system based on the Beidou system and intelligent ground nails, which can monitor cable external damage behavior in real time and accurately, and can quickly and accurately obtain its specific position and complete the evidence collection work when the cable is damaged due to construction behavior.

[0005] To achieve the above object, an underground cable anti-destruction monitoring system based on the Beidou system and intelligent ground nails includes intelligent ground nails fixed on the road surface above the buried cable line, video surveillance cameras installed at high altitudes and bound to the intelligent ground nails for taking evidence of cable external damage, and a management terminal installed with a cloud platform management system for receiving, parsing data, and being able to monitor and manage; the intelligent ground nails include a processor module and an MEMS vibration sensor module, a flash alarm module, a Beidou positioning module, a power management module, and an NB communication module electrically connected to the processor module. The intelligent ground nails are wirelessly connected to the cloud server through the NB communication module, and the cloud server is wirelessly connected to the video surveillance cameras and the management terminal through a 4G / 5G gateway and an Internet gateway respectively.

[0006] Furthermore, the intelligent ground nails further include a solar module and a battery module, and both the solar module and the battery module are electrically connected to the power management module.

[0007] Furthermore, intelligent ground nails are installed at intervals above the cable, and multiple intelligent ground nails are bound to the video surveillance cameras installed at high altitudes.

[0008] Furthermore, it further includes a mobile phone client for receiving the alarm information transmitted by the management terminal, and the mobile phone client is wirelessly connected to the cloud server through a 4G / 5G gateway.

[0009] Furthermore, the intelligent ground nails include a cylindrical hollow metal base, a top cover is installed above the metal base, a sealing ring is provided between the top cover and the metal base, and studs are installed at the bottom of the metal base and connected with expansion bolts.

[0010] Compared with the prior art, the present utility model has the following beneficial effects:

[0011] By installing intelligent ground nails above the cable, when abnormal construction occurs nearby, the MEMS vibration sensor module detects the vibration signal generated by the construction, and the flash alarm module immediately flashes the warning light to remind the on-site construction personnel to stop the construction. The Beidou positioning module transmits the occurrence time and location information of the abnormal construction event to the processor module, and transmits the abnormal construction event to the management terminal through the NB communication module. The management terminal immediately controls the video surveillance camera on-site to aim at the abnormal construction location for video evidence collection according to the abnormal construction location, realizing real-time and accurate monitoring of cable external damage behavior.

[0012] Furthermore, intelligent ground nails are installed at intervals above the cable. Multiple intelligent ground nails are bound to the video surveillance cameras installed at high places. When a certain intelligent ground nail fails, other intelligent ground nails can still work normally, ensuring the overall reliability and stability of the system. And when the intelligent ground nails within the coverage of the video surveillance cameras detect abnormal construction, the management terminal can complete the monitoring and evidence collection work only by operating one video surveillance camera, realizing the maximization of resource utilization.

[0019] To make the above objects, features and advantages of the present utility model more obvious and understandable, the present utility model will be described in detail below with reference to the drawings and specific embodiments.

[0020] As Figure 1 , 2 shown, the present utility model provides an underground cable anti - damage monitoring system based on the Beidou system and intelligent ground nails, including intelligent ground nails 1 fixed on the road surface above the buried cable line, video surveillance cameras 2 installed at high places and bound to the intelligent ground nails 1 for taking evidence of cable external damage, a management terminal 3 installed with a cloud platform management system for receiving, analyzing data and capable of monitoring and managing, and a mobile phone client 4 for receiving alarm information.

[0021] The intelligent ground spike 1 includes a processor module and an MEMS vibration sensor module, a flash alarm module, a Beidou positioning module, a power management module, and an NB communication module that are electrically connected to the processor module. The MEMS vibration sensor module is responsible for detecting minute vibrations on the ground and converting the vibration signals into electrical signals for analysis by the processor module. The flash alarm system is activated when the intelligent ground spike 1 detects a specific event or abnormal situation, warning or prompting nearby personnel or vehicles through flashing lights. This is particularly effective at night or in low visibility conditions, facilitating timely intervention or taking measures. The Beidou positioning module is used to obtain the accurate geographical location of the intelligent ground spike 1, ensuring accurate location information can be provided during an alarm. The power management module is electrically connected to a solar module and a battery module. The power management module is an intermediary between the solar and battery modules. It not only receives electrical energy from the solar module for storage but also controls the extraction of electrical energy from the battery module for use by the intelligent ground spike 1. The intelligent ground spike 1 uses narrowband Internet of Things (NB-IoT) technology to establish a wireless communication connection with a cloud server through the NB communication module. The cloud server is wirelessly connected to the management terminal 3 through an Internet gateway and is wirelessly connected to the video surveillance camera 2 and the mobile phone client 4 through a 4G / 5G gateway.

[0022] When there is abnormal construction near the installation location of the intelligent ground spike 1, the MEMS vibration sensor module detects the vibration signals generated by the construction. The flash alarm module immediately flashes the warning light to remind the on-site construction personnel to stop the construction. The Beidou positioning module transmits the occurrence time and location information of the abnormal construction event to the processor module and transmits the data to the management terminal 3 through the NB communication module. The management terminal 3 immediately controls the video surveillance camera 2 on-site to aim at the abnormal construction location for video evidence collection according to the abnormal construction location, and finally sends the alarm information to the mobile phone client 4 by text message or email to remind the relevant person in charge to handle it in a timely manner.

[0023] As Figure 3 shown, intelligent ground spikes 1 are installed at intervals above the cable. Multiple intelligent ground spikes 1 are bound to the video surveillance camera 2 installed at a high place. When a certain intelligent ground spike 1 fails, the other intelligent ground spikes 1 can still work normally, ensuring the overall reliability and stability of the system; when an intelligent ground spike 1 within the coverage of the video surveillance camera 2 detects abnormal construction, the management terminal 3 can complete the monitoring and evidence collection work by operating only one video surveillance camera 2, achieving the maximum utilization of resources.

[0024] As Figure 4As shown in the figure, the intelligent ground spike 1 includes a cylindrical hollow metal base 5. The hollow structure is used to accommodate the electronic components inside the intelligent ground spike 1, while ensuring sufficient mechanical strength and protection functions. The metal base 5 is made of corrosion-resistant metal, such as stainless steel, to ensure that it will not corrode under long-term outdoor use. A top cover 6 is installed above the metal base 5. In order to achieve effective conversion of solar energy and the light transmission effect when the indicator light flashes, the top cover 6 is made of transparent acrylic board that can provide a certain degree of protection. And in order to avoid aging caused by long-term sunlight exposure, the top cover 6 is made of anti-ultraviolet acrylic board. In order to prevent impurities such as rainwater and dust from penetrating into the intelligent ground spike 1 and damaging the electronic components, a sealing ring 7 is provided between the top cover 6 and the metal base 5. The sealing ring 7 is made of rubber material that is resistant to aging, temperature change, and ozone erosion, ensuring that the compression degree between the sealing ring 7 and the metal base 5 and the top cover 6 is appropriate, which can ensure the sealing performance and will not cause the sealing ring 7 to age quickly due to excessive compression. In order to prevent the intelligent ground spike 1 from loosening or being pulled out due to vibration or human reasons, a stud 8 is installed at the bottom of the metal base 5 and connected to an expansion bolt 9, as Figure 5 shown, which can fix the intelligent ground spike 1 more firmly and can adapt to different installation environments according to needs.

[0025] When the utility model is in use: The intelligent ground spike 1 is powered on, the management terminal 3 completes the initialization configuration, and the system starts to work. When abnormal construction occurs near the installation position of the intelligent ground spike 1, the MEMS vibration sensor module detects the vibration signal generated by the construction, and the flash alarm module immediately flashes the warning light to remind the on-site construction personnel to stop construction. The Beidou positioning module transmits the occurrence time and location information of the abnormal construction event to the processor module, and transmits the data to the management terminal 3 through the NB communication module. The management terminal 3 immediately controls the on-site video surveillance camera 2 to aim at the abnormal construction position for video evidence collection according to the abnormal construction position, and finally sends the alarm information to the mobile client 4 by text message or email to remind the relevant person in charge to handle it in time.
