[0002] Mobile inspection is an inspection task that can only be completed on the move by utilizing modern technologies such as modern mobile terminal technology, mobile communication technology, and computer technology.

[0003] The power hub is located at the hub of the power system, with a voltage level of 220kV and above. It connects multiple power sources, has many outgoing line circuits, and has a large transformer capacity. A power outage at the entire station will cause a large-scale power outage or system collapse. The power hub plays an important role in the stability and reliability of the power system operation. In order to improve the safety and stability of the power hub, the existing power hub is generally equipped with mobile inspection terminals for power hub inspections.

[0004] Most of the existing mobile inspection terminals for power hubs can only inspect the power hub as a whole.

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] See also Figure 1-Figure 4As shown, a mobile inspection terminal based on a power hub is provided, including a line planning simulation unit 10, the output end of the line planning simulation unit 10 is connected to a line abnormality response unit 20, the output end of the line abnormality response unit 20 is connected to a temperature sensing unit 30, the temperature sensing unit 30 is used to monitor the real-time temperature of each transmission line in the power hub, the output end of the temperature sensing unit 30 is connected to a video monitoring unit 40, the video monitoring unit 40 performs positioning monitoring on each transmission line in the power hub, when a line abnormality occurs, the video monitoring unit 40 will change the monitoring point, and perform all-round video of the lines within the jurisdiction area, the output end of the video monitoring unit 40 is connected to an abnormal point determination unit 50, the abnormal point determination unit 50 combines the real-time temperature of each transmission line in the power hub and the positioning monitoring, determines the position of the abnormal point after the abnormality occurs in the power hub, and then obtains the abnormal point position information, the output end of the abnormal point determination unit 50 is connected to an abnormal cause analysis unit 60, the abnormal cause analysis unit 60 analyzes the abnormal cause of the power hub line in combination with the abnormal point position information.

[0039] During specific use, the line planning simulation unit 10 simulates the line layout of the power hub online, generates an online simulation diagram of the power hub, and transmits the online simulation diagram of the power hub to the line abnormality response unit 20. The line abnormality response unit 20 monitors the power transmission of the power hub, and identifies the abnormal power situation in a short period of time, and determines whether the power transmission of the power hub is abnormal. When the power transmission of the power hub is abnormal, the temperature sensing unit 30 monitors the real-time temperature of each transmission line in the power hub and presets the normal temperature. When the temperature of a transmission line exceeds the normal temperature, the temperature sensing unit 30 in the transmission line sends out temperature abnormality information and transmits the temperature abnormality information to the video monitoring unit 40. The video monitoring unit 40 performs positioning monitoring on each transmission line in the power hub. After receiving the abnormal information, first After determining which transmission line the abnormal information is located in and the transmission line information is determined, the video surveillance unit 40 located in the transmission line will change the monitoring point, conduct all-round video surveillance of the lines within the jurisdiction, generate all-round video surveillance information, and transmit the all-round video surveillance information to the abnormal point determination unit 50. The abnormal point determination unit 50 combines the real-time temperature and positioning monitoring of each transmission line in the power hub to determine the location of the abnormal point after the abnormality occurs in the power hub, and then obtains the abnormal point location information, and transmits the abnormal point location information to the abnormal cause analysis unit 60. The abnormal cause analysis unit 60 analyzes the cause of the abnormality of the power hub line in combination with the abnormal point location information, helping maintenance personnel to lock the abnormal location and the cause of the abnormality in advance before conducting on-site maintenance, and at the same time can help operators avoid dangerous lines and reduce accidents.

[0040] In addition, the line planning simulation unit 10 includes a line planning image simulation module 110, which performs image simulation on the line layout of the entire power hub. The line planning image simulation module 110 is bidirectionally connected to the temperature control point planning module 120. The temperature control point planning module 120 is used to reasonably arrange the temperature control points to ensure that each line of the power hub can receive temperature monitoring. The line planning image simulation module 110 is bidirectionally connected to the monitoring point planning module 130. The monitoring point planning module 130 is used to reasonably arrange the monitoring points. During specific use, the line planning image simulation module 110 performs an image simulation on the line layout of the entire power hub, and the temperature control point planning module 120 reasonably arranges the temperature control points to ensure that each line of the power hub can receive temperature monitoring, and generates temperature monitoring point information, and transmits the temperature monitoring point information to the line planning image simulation module 110. The line planning image simulation module 110 adds the temperature monitoring point information into the image. At the same time, the monitoring point planning module 130 reasonably arranges the monitoring points, generates monitoring point information, and transmits the monitoring point information to the line planning image simulation module 110. The line planning image simulation module 110 adds the monitoring point information into the image, thereby forming a complete line layout image simulation of the power hub, and the temperature control points and monitoring points can be intuitively observed through the image.

[0041] Furthermore, the video monitoring unit 40 includes an abnormal line response module 410, and the output end of the abnormal line response module 410 is connected to a panoramic line camera module 420, and the panoramic line camera module 420 is used to monitor and process the entire line where the abnormality occurs. When used specifically, the temperature sensing unit 30 sends out temperature abnormality information, and transmits the temperature abnormality information to the abnormal line response module 410 of the line. After receiving the temperature abnormality information, the abnormal line response module 410 sends out response information, and transmits the response information to the panoramic line camera module 420. The panoramic line camera module 420 monitors and processes the entire line where the abnormality occurs, so as to find the location of the abnormal point of the abnormal line through the camera screen, and mark the location with an image.

[0042] Furthermore, the output end of the panoramic line camera module 420 is connected to an abnormal line length calculation module 430, which is used to calculate the length of the abnormal area of ​​the abnormal line. In actual situations, the abnormality of the line is not only a single point abnormality, but also a continuous area abnormality. At this time, if the single point marking method is used to mark the abnormal point, the marking is too dense, the process is relatively cumbersome, and the image after drawing is difficult to observe. At this time, the abnormal line length calculation module 430 is used to calculate the length of the abnormal area of ​​the abnormal line. When drawing the image later, the abnormal area after the measurement is directly marked in a centralized manner, which is convenient for maintenance personnel to observe.

[0043] Specifically, the abnormal line length calculation module 430 adopts a length offset calculation algorithm, and its algorithm formula is as follows:

[0044]

[0045] L0=VT0;L1=VT1;

[0046] L2=VT2;

[0047] D=L B -L; β = γ-α;

[0048] Where L0 is the distance from the monitoring point to the initial point O of the abnormal line, V is the propagation speed of light in the atmosphere, which is a fixed value, T0 is the time taken by the monitoring point to the initial point O of the abnormal line; L1 is the distance from the monitoring point to the abnormal point B of the abnormal line, T1 is the time taken by the monitoring point to the abnormal point B of the abnormal line, L B is the distance from the abnormal point B to the initial point O, γ is the angular offset formed by the monitoring point moving from the initial point O to the abnormal point B, L2 is the distance from the monitoring point to the abnormal point A of the abnormal line, T2 is the time spent by the monitoring point to the abnormal point A of the abnormal line, L is the distance from the abnormal point A to the initial point O, α is the angular offset formed by the monitoring point moving from the initial point O to the abnormal point A, D is the length of the abnormal area, and β is the angular offset formed by the monitoring point moving from the abnormal point A to the abnormal point B.

[0049] In addition, the input end of the abnormal cause analysis unit 60 is connected to the output end of the line planning simulation unit 10. In specific use, during the abnormal cause analysis process, the line planning simulation unit 10 transmits the power hub online simulation diagram to the abnormal cause analysis unit 60, and the abnormal cause analysis unit 60 analyzes the abnormal points and the abnormal areas on the power hub online simulation diagram in combination with the power hub online simulation diagram, and compares them in the diagram, so as to help the operator analyze the abnormal cause more intuitively and find a solution in time.

[0050] Furthermore, the temperature sensing unit 30 is bidirectionally connected to an emergency stop unit 70, and the emergency stop unit 70 is bidirectionally connected to the video monitoring unit 40. The emergency stop unit 70 is used to set a temperature threshold. When the temperature sensing unit 30 monitors the abnormal temperature, the temperature of the abnormal point of the line continues to increase. When the temperature of the abnormal point of the line exceeds the temperature threshold, if the temperature sensing unit 30 continues to work, it is easy to cause the temperature sensing unit 30 to fail due to excessive temperature. At this time, the temperature sensing unit 30 is stopped in time by the emergency stop unit 70, and the temperature sensing unit 30 and the video monitoring unit 40 are stopped from continuing to work. At the same time, the later maintenance personnel are notified that the temperature at the abnormal line position exceeds the threshold, and they need to be cautious during the maintenance process.

[0051] Furthermore, the output end of the emergency stop unit 70 is connected to an abnormal data summarization unit 80, which is used to summarize and integrate the abnormal line data after the emergency stop. Since the emergency stop unit 70 will stop the temperature sensing unit 30 and the video monitoring unit 40 from working after the temperature exceeds the threshold, at this time, part of the data judged by the temperature sensing unit 30 and the video monitoring unit 40 will not be transmitted in time, resulting in omissions in the abnormal cause analysis process, which will affect the subsequent maintenance. At this time, the data after the emergency stop is timely summarized and stored by the abnormal data summarization unit 80 to prevent the loss of the stop data.

[0052] In addition, the output end of the abnormal data summarization unit 80 is connected to the input end of the abnormal cause analysis unit 60. The abnormal data summarization unit 80 summarizes and stores the data after the emergency stop in a timely manner, and transmits the data after the emergency stop to the abnormal cause analysis unit 60 after backing up, so that the analysis result of the abnormal cause analysis unit 60 is more accurate.
