Description

Technical Field

[0001] The present invention relates to the technical field of power protection monitoring, and particularly relates to an overhead line collision and abnormal movement monitoring device and a monitoring method thereof. Background Art

[0002] During the operation of overhead lines, they may be impacted by foreign objects, including birds, shells, the robotic arms of work vehicles, etc. On the one hand, the collision has a destructive effect on the line body, and on the other hand, it will also cause harm to the acting object. When the line undergoes collision and abnormal movement, the most intuitive reflection is that the line generates vibration. Monitoring and capturing this vibration signal can effectively monitor whether the line has undergone collision and abnormal movement.

[0003] Case of bird mis-collision: In recent years, there have been multiple cases of rare wild birds such as black-necked cranes mis-colliding with transmission lines in the Tibet region, resulting in casualties of rare birds such as black-necked cranes, swans, and grey cranes, which has attracted the high attention of departments such as the National Forestry and Grassland Administration and bird protection agencies.

[0004] Currently, whether there are foreign objects around the overhead lines in the corridor is achieved through video monitoring. Specifically, cameras are used to shoot the corridor environment to identify whether there are foreign objects in the corridor. However, there is no effective monitoring method for whether the foreign object has collided with the line. In fact, for grounded foreign objects such as vehicles, when the line is energized, a discharge channel is generated even when the robotic arm has not collided with the line, resulting in a trip, and the foreign object is detected as soon as it approaches. However, for overhead lines during the construction process or power outage maintenance process, it is difficult to detect foreign object impacts. For non-grounded foreign objects such as birds, shells, and drones, it is difficult to detect the process of their mis-collision with the line through video means.

[0005] To effectively monitor the process of rare birds mis-colliding with transmission lines and timely discover the behavior of rare birds mis-colliding with the line, it is necessary to monitor the collision and abnormal movement of overhead lines. Summary of the Invention[[ID=2,0]]

[0047] Example 1:

[0048] As Figure 1 shown, a monitoring device for abnormal collisions of overhead lines includes:

[0049] The first half shell 1, with a first wire groove provided in the middle thereof;

[0050] The second half shell 2, with a second wire groove provided in the middle thereof, and one end of which is hinged to one end of the first half shell 1; the first wire groove and the second wire groove together form a through hole for fixing the overhead line;

[0051] The wedge-shaped pressing piece 3 is located between the other end of the first half shell 1 and the other end of the second half shell 2. When the first half shell 1 and the second half shell 2 are locked and fixed to the overhead line, under the extrusion action, the wedge-shaped pressing piece 3 slides and presses the overhead line;

[0052] The vibration acquisition component is fixed to the wedge-shaped pressing piece 3;

[0053] The vibration acquisition component is used to obtain the vibration acceleration value of the overhead line, and determine whether it is a foreign object impact according to the vibration acceleration value, so as to transmit the vibration acceleration value of the foreign object impact to the server.

[0054] After the first half shell 1 and the second half shell 2 are joined together, they form a cylindrical structure with a through hole in the middle. The through hole in the middle is formed by the first wire groove and the second wire groove. The diameter of the through hole is the same as the diameter of the overhead line. The wedge-shaped pressing piece 3 that is cooperatively pressed presses the overhead line to form a fixed connection; the vibration acquisition component is provided on the wedge-shaped pressing piece 3. The vibration acceleration value of the overhead line is collected through the vibration acquisition component. When the vibration acceleration value exceeds the set limit, the vibration acquisition component will collect the vibration acceleration value of the overhead line and analyze the vibration acceleration value, so as to judge the abnormal situation of the overhead line.

[0055] When the first half shell 1 and the second half shell 2 are closed, they hold the overhead line tightly and, together with the wedge-shaped pressing piece 3, support the overhead line to form a fixed connection; the two half shells are tightly fitted together to provide uniform radial pressure, preventing loosening or falling off from the overhead line under wind, ice and snow loads or external forces, and all components are arranged in the shell to support disassembly and reinstallation, facilitating maintenance or replacement of components. At the same time, the shell can block the intrusion of rain and condensation, protecting the vibration collection components and reducing the risk of corrosion;

[0056] The wedge-shaped pressing piece 3 presses the overhead line and transmits the vibration to the vibration collection component, which greatly increases the accuracy and sensitivity of the data collection of the monitoring device. The structure of the wedge-shaped pressing piece is as follows: Figure 2 As shown; the wedge-shaped pressing piece 3 presses the overhead line. The invention applies an ingenious design and uses a bolt tightening structure to squeeze the wedge-shaped pressing piece 3. The overhead line can be compressed by controlling the tightening force of the bolt. The wedge-shaped pressing piece 3 and the overhead line directly transmit vibration force, and the vibration amount of the measuring wire is converted into the vibration amount of the measuring wedge-shaped pressing piece 3. It is original, simple and ingenious.

[0057] The vibration collection component constantly monitors the vibration conditions on the overhead wires and obtains the vibration acceleration values of the overhead lines. When the vibration acceleration is within the limit, it is identified as a disturbance caused by wind load, and the vibration acceleration value is small and not collected. When the vibration acceleration value exceeds the limit, it is identified as monitoring the collision of the overhead line, triggering the vibration collection function, collecting the vibration acceleration value within three seconds, and sending the vibration acceleration value to the server for analysis, prompting on-site problem handling in time, protecting the line, and for the problem of rare birds accidentally colliding with the line, the on-site accidental collision can be discovered in time, the injured birds can be rescued, and the ecology of the rare bird population can be protected.

[0058] Preferably, the vibration collection component includes:

[0059] A vibration sensor 4 is fixed to the side of the wedge-shaped pressing piece 3 pressing the overhead line;

[0060] a control circuit 5 , mounted in the second half shell 2 and connected to the vibration sensor 4 ;

[0061] The battery 6 is installed in the first half shell 1 and connected to the control circuit 5 . The battery 6 and the control circuit 5 are arranged in parallel.

[0062] like Figure 3 As shown, the vibration sensor 4 is arranged on the wedge-shaped pressing piece 3 and close to the side abutting the overhead line, receiving the vibration of the overhead line transmitted from the wedge-shaped pressing piece 4. The vibration sensor is embedded in the pressing piece, and no additional mounting bracket is required, which significantly improves the state perception capability of the overhead line;

[0063] like Figure 4As shown, the control circuit 5 is arranged in the second half shell;

[0064] As Figure 5 shown, the battery 6 is arranged in the first half shell;

[0065] The control circuit 5 and the battery 6 are arranged opposite and parallel to each other, and are respectively located in the second half shell 2 and the first half shell 1, so that the weights of the first half shell 1 and the second half shell 2 are balanced.

[0066] Preferably, the battery 6 is a thin-film solar cell with a specification of 10000 mAh lithium iron phosphate.

[0067] The thin-film solar cell has strong low-light power generation ability and can still generate electricity on cloudy days, in the early morning or at dusk, improving energy utilization efficiency; at the same time, the thin-film solar cell has good anti-shadow performance and can still maintain a certain power generation efficiency when partially shaded, which is superior to traditional crystalline silicon cells.

[0068] The lithium iron phosphate battery is a high-energy density battery, and its 10000 mAh capacity can store sufficient electric energy to meet the long-term power supply requirements such as outdoor equipment and emergency power supplies. Moreover, the lithium iron phosphate battery can be charged and discharged stably, support the fluctuating input of the solar cell, and avoid damage caused by overcharging / overdischarging.

[0069] Preferably, the control circuit 5 uses a single-chip microcomputer as the control core.

[0070] The single-chip microcomputer can integrate modules such as CPU, memory (ROM / RAM), timer, ADC / DAC, PWM, and communication interface (UART / I2C / SPI), greatly reducing the number of peripheral components, reducing the circuit complexity, and its miniaturized volume is suitable for compact devices, saving space.

[0071] The single-chip microcomputer also has flexible programmability, and its algorithm can be freely customized to adapt to different application requirements and corresponding abnormal situations that may be encountered in different regions or environments.

[0072] The single-chip microcomputer has high precision and real-time performance, and can accurately control and respond quickly.

[0073] The single-chip microcomputer has anti-interference design and can adapt to harsh environments.

[0074] Preferably, the control circuit 5 further includes:

[0075] A power control circuit, which is respectively connected to the battery 6 and the single-chip microcomputer;

[0076] A communication module, which is connected to the single-chip microcomputer and sends the data transmitted by the vibration sensor 4 received by the single-chip microcomputer to the server.

[0077] As Figure 6 shown, the control logic structure of the control circuit includes: the thin-film solar panel and the battery 6 supply power to the single-chip microcomputer, i.e., the MCU, through the power control circuit. The vibration acceleration sensor sends the obtained vibration acceleration value of the overhead line anomaly to the single-chip microcomputer, and transmits the vibration acceleration value of the anomaly to the communication module through the single-chip microcomputer.

[0078] As Figure 7 shown, the first half shell 1 and the second half shell 2 press the wedge-shaped pressing piece 3 through fastening bolts.

[0079] The holes on the wedge-shaped pressing piece 3 are larger than the bolt fixing holes of the first half shell 1 and the second half shell 2, providing space for the movement of the pressing piece. When the bolts are tightened, the wedge-shaped pressing piece 3 can be pressed down to make the wedge-shaped pressing piece 3 hold against the overhead line, forming a fixed connection with the overhead line; the pressing piece tightly presses the overhead line, avoiding the rubber path and greatly increasing the accuracy and sensitivity of the data collection of the monitoring device.

[0080] Preferably, rubber is lined between the first wire groove and the second wire groove and the overhead line.

[0081] The rubber is arranged on the inner lining of the part where the first wire groove and the second wire groove hold the overhead line tightly, avoiding direct fatigue wear of the wire strands at the edge of the device, preventing the dynamic bending strain at the outlet of the device from exceeding the limit, and preventing the damage to the line caused by the installation of the device.

[0082] Embodiment 2:

[0083] Based on the same inventive concept, the present invention also provides a method for monitoring the collision and anomaly of an overhead line. As Figure 8 shown, it is realized by using a monitoring device for the collision and movement of an overhead line as described above. The method includes:

[0084] The vibration acquisition component acquires the vibration acceleration value of the overhead line;

[0085] Judge whether the vibration acceleration value exceeds the limit;

[0086] Collect the vibration acceleration value that exceeds the limit, and transmit the collected vibration acceleration value to the server to process and analyze the foreign object impact situation.

[0087] As Figure 9 shown, the monitoring steps of the method for detecting the collision and movement of an overhead line include:

[0088] The first step: Turn on the vibration acquisition component;

[0089] The second step: Monitor the vibration acceleration value of the overhead line through the vibration acquisition component;

[0090] Step 3: Determine whether the vibration acceleration value exceeds the limit. If the value does not exceed the limit, return to step 2 to re-monitor the vibration acceleration value of the overhead line. If the value exceeds the limit, proceed to the next step.

[0091] Step 4: The vibration acceleration value that exceeds the limit is the collision abnormal value;

[0092] Step 5: Start the acquisition program to collect three seconds of vibration acceleration data, open the network connection, and send the vibration acceleration data to the server through the dedicated network;

[0093] Step 6: The server receives the vibration acceleration value and stores the data after analyzing it.

[0097] When the vibration acceleration value exceeds the limit, it is considered a collision abnormality and the collection of 3s vibration data is started.

[0098] Data collection adopts a triggering mode. When the vibration acceleration value is found to be out of limit, data collection starts. For the disturbance caused by wind load, the vibration acceleration value is small and is not collected, which effectively shields the vibration disturbance caused by wind load.

[0099] Preferably, the calculation formula of the vibration acceleration value is as follows:

[0100]

[0101] Where E is the short-time energy, its unit is g 2 ;a x 、a y and a z are the acceleration values of the xyz axes, respectively, in g; f s is the sampling frequency (e.g., 1000 Hz, N = 50 points).

[0102] If the instantaneous acceleration in any axis exceeds the threshold, it is determined that a foreign object impact has occurred. The calculation formula is as follows:

[0103] max(|a x [t]∣,∣a y [t]∣,∣a z [t]∣)>a th

[0104] Among them, a th is the minimum measurable impact a th The typical value of is 0.5g (the minimum measurable impact of common foreign objects such as bird pecks and plastic films);

[0105] If the instantaneous acceleration in any axial direction does not exceed the threshold, it is determined as the disturbance caused by wind load.

[0106] Preferably, the transmission of the collected vibration acceleration value to the server includes:

[0107] Transmitting the collected vibration acceleration value to the server for processing and analysis through a 4G network, or transmitting the collected vibration acceleration value to the edge IoT agent through Bluetooth / ZigBee and then centrally sending it to the server.
