Description

Technical Field

[0001] This utility model relates to the field of marker post technology, and in particular to a cable monitoring marker post. Background Technology

[0002] With the continuous acceleration of urbanization, the frequency of urban infrastructure construction projects has increased significantly. High-voltage cables, as the core energy transmission carrier of urban power supply systems, are generally buried in underground cable trenches or tunnels and are key infrastructure to ensure the continuity of electricity supply for urban production and daily life. However, external interference such as construction machinery misoperation and illegal construction has become the primary cause of transmission line failures. The average time to handle such failures exceeds 4 hours, often causing large-scale power outages, affecting not only citizens' lives and business production but also posing a serious threat to the reliability of urban power supply. Among these, mechanical construction, due to its high intensity and wide impact, has become a major source of risk. Precise management and real-time monitoring of high-voltage cables have become core requirements for their safe operation.

[0003] The current traditional cable channel management model has many insurmountable technical defects: On the one hand, management mainly relies on manual inspection, which is costly and inefficient, and cannot achieve real-time monitoring around the clock. Blind spots are significant at night and in severe weather, making it difficult to detect potential risks in a timely manner. On the other hand, because high-voltage cables are buried underground, construction personnel often do not know their route and depth. Standardized construction requires on-site guidance from power personnel, but some construction units or individuals often carry out construction without reporting or notification in order to shorten the construction period. Traditional methods lack real-time early warning capabilities, and often the damage to the cable is only discovered after it has been damaged, missing the opportunity for intervention. In addition, existing monitoring equipment has shortcomings in communication technology. Not only does it have high power consumption leading to short standby time and increased maintenance costs, but it also requires distributed deployment of receiving hosts due to limited communication distance, increasing hardware costs and network complexity. Furthermore, the data transmission security is insufficient, posing a risk of leakage, and it is difficult to meet the stringent requirements of the power system. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is to overcome the problems of high power consumption, short communication distance, high hardware cost and insufficient data transmission security of existing monitoring equipment, thereby providing a cable monitoring marker post.

[0005] To solve the above-mentioned technical problems, this utility model provides a cable monitoring marker post, comprising: First housing, second housing, cover plate, solar panel, mainboard, power module and vibration acquisition module; The solar panel is disposed on the side of the first housing facing the cover plate; the main board is disposed on the side of the first housing away from the solar panel; the power module is disposed on the side away from the main board and away from the first housing; the first housing and the second housing are fastened together to form a cavity; the main board and the power module are disposed in the cavity; and the vibration acquisition module is connected to the main board.

[0006] In one embodiment of the present invention, the first housing is provided with a groove on the side facing the cover plate, and the solar panel is disposed in the groove.

[0007] In one embodiment of the present invention, the cover plate is embedded in the groove of the first housing; the surface of the cover plate away from the solar panel is flush with the surface of the groove.

[0011] In one embodiment of this utility model, the communication module includes a Zigbee submodule and a CAT1 communication submodule; wherein, both the Zigbee submodule and the CAT1 communication submodule are connected to the main control chip.

[0012] In one embodiment of this utility model, the leads of the solar panel are connected to the motherboard.

[0013] In one embodiment of this utility model, the cover plate is provided with a transparent area, which corresponds to the position of the solar panel's collection surface.

[0014] In one embodiment of this utility model, the interior of the second housing is filled with waterproof adhesive, and the first housing and the second housing are fastened together to form a cavity sealed with waterproof adhesive.

[0015] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial effects: (1) The cable monitoring marker post described in this utility model places the solar panel on the front of the first housing to maximize sunlight-driven power generation; the main board is adjacent to its back to shorten the power supply path and reduce line loss; the power module is then stacked below the main board. The three are stacked along the same axis, resulting in a compact space, low center of gravity, and good vibration resistance.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0022] Example: Reference Figures 1 to 2 As shown, this utility model provides a cable monitoring marker post, comprising: The components include: first housing 3, second housing 6, cover plate 1, solar panel 2, main board 4, power module 5, and vibration acquisition module; The solar panel 2 is located on the side of the first housing 3 facing the cover plate 1; the main board 4 is located on the side of the first housing 3 away from the solar panel 2; the power module 5 is located on the side away from the main board 4 and away from the first housing 3; the first housing 3 and the second housing 6 are fastened together to form a cavity; the main board 4 and the power module 5 are located inside the cavity; the vibration acquisition module is connected to the main board 4.

[0023] This utility model discloses a cable monitoring marker post, employing a highly efficient vibration monitoring structure that enables accurate monitoring of ground vibration. The solar panel 2 is placed on the front of the first housing 3 to maximize solar power generation; the main board 4 is adjacent to its back, shortening the power supply path and reducing line loss; the power module 5 is then stacked below the main board 4. All three are stacked along the same axis, resulting in a compact design, low center of gravity, and good vibration resistance. The first housing 3 and the second housing 6 interlock to form a sealed cavity, completely enclosing the main board 4 and power module 5, preventing rainwater and dust intrusion, thus achieving both heat dissipation and protection, and providing advantages such as high integration, high reliability, and easy assembly. Furthermore, this structural design improves the marker post's operational stability in waterlogged environments, its structural strength under vehicle pressure, and the accuracy of construction alarms.

[0024] Specifically, the first housing 3 has a groove on the side facing the cover plate 1, the depth of which matches the thickness of the solar panel 2, and the solar panel 2 is disposed within the groove. Furthermore, the cover plate 1 is embedded within the groove of the first housing 3, with the surface of the cover plate 1 furthest from the solar panel 2 flush with the surface of the groove. In other words, the surface of the cover plate 1 is flush with the outer surface of the outer casing around the groove, forming a smooth, unprotruding, and complete appearance. This avoids lateral impacts to the solar panel 2 and prevents the cover plate 1 from warping due to external forces, achieving both structural protection and aesthetic appeal.

[0025] Furthermore, regarding the material of the cover plate 1, this embodiment preferably uses acrylic sheet. This material is lightweight and high-strength, more impact-resistant than traditional glass, and less prone to breakage, effectively reducing the load on the top of the pile. Acrylic has a smooth surface and excellent light transmittance, ensuring the solar panel 2 receives sufficient sunlight. It also possesses excellent weather resistance, resisting yellowing or embrittlement even under prolonged sun and rain or in low-temperature environments, resulting in a long service life. Acrylic is also easy to process and mold, allowing for a tight fit with the groove in the first housing 3, achieving a smooth embedding and improving overall sealing and aesthetics. In addition, its surface is not prone to dust accumulation, making cleaning and maintenance convenient, and minor scratches can be easily repaired to restore transparency.

[0026] Furthermore, the cover plate 1 has a transparent area in the center corresponding to the solar panel 2, while the rest can be shaded to ensure effective light collection and hide the internal structure.

[0027] Specifically, the vibration acquisition module includes at least one vibration sensor 7. The vibration sensor 7 is disposed on the inner wall of the second housing 6. When multiple vibration sensors 7 are configured, each sensor is arranged on the inner wall of the second housing 6 at a preset interval.

[0028] Furthermore, the vibration sensor 7 is fixed by using highly elastic solid adhesive to firmly bond the sensor to the side wall of the marker post, allowing vibration energy to be directly transmitted to the sensing unit with minimal loss. The vibration waves generated by mechanical construction on the road surface spread horizontally in all directions, and the wavefront that first reaches the marker post can be transmitted directly inward along the side wall. In this embodiment, the sensor is placed on the inner wall, which maximizes the capture of effective signals and significantly reduces attenuation. In contrast, traditional smart marker posts generally place the vibration sensor 7 at the bottom of the post, such as... Figure 3 As shown, the vibration wave needs to diffract to the bottom before it can be sensed, which results in a longer path and greater energy loss, making it easy to miss or false alarms.

[0029] Specifically, refer to Figure 4As shown, the motherboard 4 includes a main control chip and a communication module, with the main control chip connected to both the communication module and the power module 5. In this embodiment, the main control chip is preferably an MCU main control chip. The MCU main control chip and vibration sensor 7 work together to achieve accurate detection of equipment vibration status. The specific workflow is as follows: Vibration sensor 7 transmits the acquired vibration data to the MCU main control chip. The MCU main control chip identifies the vibration signal and compares the identified vibration characteristic parameters (such as vibration frequency, amplitude, and duration) with preset benchmark thresholds (written in advance to the MCU storage unit according to safety standards or equipment operating parameters for different application scenarios). If the identification result meets the normal operating threshold range (i.e., it is not related to mechanical construction), the MCU main control chip generates a normal equipment status command and feeds it back to the host computer or cloud monitoring system in real time through the communication module. If the identification result exceeds the benchmark threshold (such as abnormal high-frequency vibration or excessive amplitude impact, which is caused by mechanical construction), the MCU main control chip immediately triggers an alarm mechanism, sends an abnormal alarm signal through the communication module, and simultaneously uploads specific abnormal vibration data (including the time of abnormality and characteristic parameters). At the same time, it records this abnormal event to the local storage unit for subsequent fault investigation and tracing. In addition, to improve recognition accuracy, the MCU main control chip will also preprocess the raw data transmitted by the vibration sensor 7. Specifically, it will first filter out noise signals introduced by environmental interference (eliminating low-frequency noise or instantaneous pulse interference through the built-in filtering unit), then convert the preprocessed effective data into standardized digital signals, and then execute the vibration recognition process to ensure the reliability of subsequent threshold comparison and decision instructions.

[0030] Furthermore, the motherboard 4 also includes a positioning chip, which is connected to both the main control chip and the communication module. In this embodiment, the positioning chip is preferably a Beidou positioning chip, which integrates initial acquisition, real-time collection, and tracking adjustment functions for positioning information. During the deployment phase of the marker stakes, it can receive Beidou satellite signals to generate original location information and transmit it to the main control chip for storage. On a daily basis, it collects real-time positioning data at preset initial intervals and feeds it back to the main control chip. The main control chip compares the real-time positioning data with the original location information through its built-in position comparison unit. For example, when the displacement is determined to be ≥0.5 meters, the positioning chip is triggered to shorten the collection interval to 10-30 seconds and sends an alarm signal containing the device identifier and abnormal location to the cloud platform through the communication module. At the same time, the positioning chip continues to collect new positioning information in the abnormal location state, which is processed by the main control chip and pushed to the cloud platform in real time through the communication module until it receives the device retrieval confirmation signal forwarded by the main control chip and then resumes the initial collection interval.

[0031] Furthermore, the communication module includes a Zigbee submodule and a CAT1 communication submodule. Both submodules are connected to the main control chip and are responsible for near-end low-power networking and far-end backhaul, respectively. The reason for preferring Zigbee for local communication in this invention is that the Zigbee submodule operates at a current of only 5mA, significantly lower than Wi-Fi (10–50mA), Bluetooth (20mA), and UWB (10–50mA). The marker post described in this embodiment is normally in a deep sleep state of 10–20µA, only waking up in milliseconds to send tens of bytes of data. This submodule, with its ultra-low power consumption characteristics of microampere-level sleep and milliampere-level transient, combined with a transmission rate of 250kbps (sufficient to complete small packet data transmission in one go), and its long-sleep, short-wake operating mode, is precisely adapted to extremely low-power scenarios. Furthermore, the CAT1 communication submodule is preferred in this invention because: the CAT1 communication submodule is based on the existing 4G network, which has the advantages of wide coverage and no risk of 2G / 3G network shutdown; it supports 10M downlink / 5M uplink speed, with latency down to the millisecond level, and is compatible with VoLTE; the current in sleep mode is only in the microamp level, and it can achieve five years of battery life with two batteries; at the same time, the module is compact, easy to solder and bond, and its cost is only half that of CAT4, and its comprehensive performance is suitable for remote backhaul requirements.

[0032] Furthermore, the Zigbee submodule employs a Mesh self-organizing network approach, effectively expanding network coverage and improving communication reliability through a multi-hop relay mechanism between devices. In the Mesh network, each node not only has data acquisition capabilities but also acts as a relay node to forward data, achieving true multi-hop communication. Even if a node fails, other nodes can automatically reselect a routing path, ensuring data transmission continuity and the network's self-healing capabilities. When a communication path is interrupted due to node failure or external interference, the Zigbee submodule can dynamically adjust the route, allowing data to bypass the failed node and be successfully transmitted to the target node (such as a 4G gateway) via other available paths. This mechanism significantly enhances the anti-interference capability and transmission distance of Zigbee wireless communication, ensuring that monitoring information is stably and reliably transmitted from the source to the 4G gateway and further uploaded to the cloud monitoring platform. In addition, due to the network-wide sharing characteristic of the Mesh network, as long as any smart marker node successfully connects to the network, it can receive and forward monitoring data from all nodes in the entire network. This feature greatly reduces the restrictions on the deployment location of 4G gateways, making their deployment more flexible and efficient, especially suitable for monitoring scenarios with complex terrain or wide coverage.

[0033] Furthermore, referring to Figure 5As shown, the Zigbee submodule's data encryption mechanism is based on the AES-128 encryption algorithm to build a security framework, supporting the generation, distribution, and storage of security keys. This effectively prevents data eavesdropping and malicious device manipulation, working in synergy with the hardware security design of the integrated energy harvesting and storage structure to jointly ensure the overall security of the cable monitoring marker posts. The Zigbee submodule adopts three core security modes defined by the Zigbee protocol: Network Key mode, which uses a pre-shared network security key for encryption, adapting to scenarios with large-scale device access; Unique Link Key mode, which generates a unique link key for each device connection, enhancing communication security through key differentiation, particularly suitable for the instruction and data transmission of key components such as the vibration sensor 7 and the solar energy harvesting component in this embodiment; and Distributed Trust Center mode, where a network trust center uniformly manages the distribution and lifecycle of devices and keys, linking with the functional control components of the motherboard 4 to strengthen the standardization of key management. In actual implementation, the encryption process is closely integrated with the hardware structure, specifically including: first, selecting an appropriate security mode (such as the unique link key mode) based on the network scale and the deployment scenario of the marker stakes; the function control component of the motherboard 4 generates a link key or network key based on ECC (elliptic curve cryptography algorithm), which is then distributed to each device through a secure channel; then, the transmitted data is encrypted using the AES-128 algorithm; and finally, data integrity verification is completed using HMAC or CCM mechanisms to ensure that data related to the energy harvesting, sensing and detection functions in this embodiment is secure and reliable during transmission.

[0034] This invention employs Zigbee low-power wireless communication, solving the problems of high power consumption and inability to remain on standby for extended periods in existing smart marker piles. This extends the operating time of the device on a single power supply, reduces maintenance operations, avoids monitoring interruptions, and improves the practicality and reliability of the equipment. The Zigbee wireless mesh network communication method addresses the issues of short communication distances and the cost of deploying multiple receivers, achieving full signal coverage, reducing hardware costs, simplifying deployment processes, and improving equipment deployment flexibility. Furthermore, this invention's wireless communication method solves the problem of data leakage from marker piles. Its secure encryption mechanism protects transmitted data, prevents security risks, meets the data security requirements of the power system, and ensures the integrity and confidentiality of monitoring data.

[0035] Specifically, the leads of the solar panel 2 are connected to the main board 4 to provide real-time power replenishment to the various modules of the main board 4 (including the main control chip, positioning chip, communication module, etc.); the power module 5 includes a battery (e.g., a lithium battery), and the solar panel 2 and the power module 5 are connected through a charge and discharge management circuit. The charge and discharge management circuit is integrated on the main board 4 and can stably input the electrical energy converted by the solar panel 2 into the lithium battery for storage, and monitor the power status of the lithium battery. When the power exceeds the maximum predetermined value, the charging circuit is automatically cut off to avoid overcharging.

[0036] Furthermore, the interior of the second housing 6 is pre-filled with waterproof adhesive. After the first housing 3 and the second housing 6 are fastened together, a sealed cavity is formed by the sealing effect of the waterproof adhesive, ensuring that the interior of the cavity reaches the IP68 waterproof rating. During the production of the marker post, the main board 4 can be first fastened to the preset position inside the bottom shell (i.e., the second housing 6) using fixing posts or screws to ensure that the main board 4 and the bottom shell do not wobble relative to each other; then, the solar panel 2 is embedded into the mounting groove (i.e., the groove) of the upper shell (i.e., the first housing 3), and special sealant is applied along the edge of the solar panel 2 for fixation. The thickness of the sealant layer is controlled at 0.5-1mm to ensure that the solar panel 2 is tightly attached to the first housing 3 and achieves a seal; then, the leads of the solar panel 2 are combed and passed through the preset wire holes of the first housing 3 (the holes are pre-coated with waterproof adhesive). The first housing 3 is precisely connected to the power interface of the mainboard 4, and the interface is wrapped with insulating tape to prevent short circuits. Then, waterproof glue is slowly poured into the second housing 6, with the amount of glue enough to completely cover the mainboard 4 and internal components, and the glue surface is flush with the edge of the second housing 6. Let it stand for 24 hours to allow the waterproof glue to fully cure. Finally, the first housing 3 and the second housing 6 are precisely aligned and fastened together, ensuring that the leads of the solar panel 2 are not squeezed or tangled during the fastening process. After fastening, it is locked with buckles or screws, so that the waterproof glue further fills the gaps in the housing, completing the overall sealing and assembly of the equipment.

[0037] Furthermore, for the connection between the first housing 3 and the second housing 6, the following exemplary structure can be used to achieve a stable assembly.

[0038] For example, the first housing 3 has through holes of appropriate diameter at its four corners, and the corresponding positions of the second housing 6 have integrally formed screw caps 9 with internal threads (the height of the screw caps 9 matches the wall thickness of the second housing 6, and the top end face is flush with the inner wall of the second housing 6); at the same time, the four corners of the main board 4 also have through holes corresponding to the positions of the screw caps 9 (the hole diameter is slightly larger than the screw rod diameter). During assembly, the screws 8 pass through the through holes of the first housing 3 and the main board 4 in sequence, and then connect with the screw caps 9 of the second housing 6 by threading. By evenly tightening the four screws 8 (the tightening torque is controlled at 2-3 N·m), the first housing 3 and the second housing 6 are tightly fastened together, and the main board 4 is stably clamped between the two housings without loosening. The overall structure of the marker post after fastening is compact, and the heads of the screws 8 are completely sunk into the through holes of the first housing 3 (the top of the through hole has a countersunk groove), avoiding protruding surfaces that may affect passage. Its assembled state is as follows. Figure 2 As shown.

[0039] Specifically, refer to Figure 6 As shown, the specific application steps of this embodiment are as follows: First, a circular countersunk hole is drilled on the road surface using a water drill. The hole diameter and depth are determined according to the specifications of the pile (i.e., the overall marker pile) and the road structure. After drilling, the dust and water inside the hole are removed, and an appropriate amount of concrete is poured at the bottom of the hole as a cushion layer. The thickness of the cushion layer is sufficient to ensure that the pile is firmly embedded and that the top is flush with the road surface. Then, the intelligent marker pile is vertically placed into the cushion layer and finely adjusted to the design elevation to ensure a smooth connection between the pile and the road. After the concrete solidifies, the cushion layer, the pile, and the road surface form a continuous whole, allowing vibration waves from the road surface to be directly and unobstructedly transmitted to the intelligent marker pile, thus improving the sensitivity of subsequent monitoring.

[0040] Furthermore, referring to Figure 7 As shown in the figure, the marker post described in this embodiment is installed on the ground above the high-voltage cable channel. After installation, it is at the same level as the ground. Without affecting the passage of pedestrians and vehicles, it can monitor in real time whether there is mechanical construction activity nearby. When mechanical construction is found, it will promptly alarm the person in charge and remind them to go to the construction site for supervision and guidance.

[0041] This invention achieves low-power operation by optimizing the data transmission mechanism, extending equipment operating time and reducing total lifecycle costs, while ensuring continuous and stable monitoring. The marker post also improves wireless data transmission distance and network stability, reducing the number of receiving hosts required, which not only lowers hardware costs but also makes deployment more flexible. Furthermore, the intelligent marker post is equipped with a highly secure data encryption mode, effectively preventing data leakage and tampering, meeting the data security requirements of the power system. Simultaneously, it employs high-precision vibration monitoring technology, accurately identifying external interference, significantly reducing false alarm rates, and providing efficient and reliable support for protecting cable channels from external damage.

[0042] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
