Technical Field
[0001] The present invention relates to the technical field of cable joint monitoring, and in particular to an all-terrain cable joint stability monitoring system and a monitoring method thereof. Background Art
[0002] In the current existing technology, there are a huge number of cable joints, and the quality of the joints is directly related to the safety of the entire power grid. Therefore, it is necessary to strictly inspect the key parts of the joints. The various faults that occur at the cable joints are not a sudden process, but because the temperature at the joints continues to rise, causing the insulation to gradually age and the leakage current to gradually increase. After reaching a certain level, breakdown occurs. It is a process from quantitative change to qualitative change. However, it is difficult for existing detection technologies to effectively capture this process from quantitative change to qualitative change. It is mainly limited to the detection of the physical state of the joints, and it is impossible to monitor the changing trends of the joint temperature and leakage current in real time, resulting in difficulty in early warning of faults.
[0003] However, the existing technology still has some shortcomings, such as the following aspects: When testing cable joints, they are easily affected by external factors, which sometimes lead to deviations in the test data, thus affecting the accuracy of the test results, making it impossible for staff to find the problem after arriving at the site, and when the problem is detected, it is impossible to accurately find the root cause of the problem. Summary of the invention

[0006] Preferably, a signal comparison module is connected to the initial detection device and the final detection device via a network, and the signal comparison module is used to receive data from the initial detection device and the final detection device, and upload the data after comparison between the initial detection device and the final detection device to the data acquisition terminal.
[0007] Preferably, the detection module includes a sensor, which is used to detect cables and transmission lines. A signal collector is connected to the sensor via a network. The signal collector is used to collect and analyze various signals based on sensor data, and perform digital conversion based on the signals collected and analyzed by the signal collector.
[0008] Preferably, the detection module includes an operation status monitoring box, which is used to detect the power flowing through the cable and upload the power according to the flow data.
[0009] Preferably, the monitoring platform includes manual operation, and the manual operation is used to verify the data transmitted by the signal comparison module, and to initiate a secondary detection to verify the first detection based on the data transmitted by the signal comparison module.
[0010] Preferably, the monitoring platform includes a positioning warning module, and the positioning warning module is used to perform positioning according to data collected by the data acquisition terminal, and contact nearby staff according to the positioning.
[0011] Preferably, the monitoring platform includes a remote control module, which is used to connect to the detection module via a network and emit different indicator lights according to the situation.
[0012] According to the above technical solution of an all-terrain cable joint stability monitoring system, an all-terrain cable joint stability monitoring method is also provided, comprising the following steps: Step 1: Start the detection module to detect the interface between the cables, start the sensor to detect the cables at both ends of the interface, and then transmit the detected data to the signal collector. The data detected by the sensor is uploaded to the data acquisition terminal through the signal collector. At the same time, the cable detection is uploaded using the operation status monitoring box to ensure the accuracy of the comparison results of the two sets of data; Step 2: Start the initial detection device, the end detection device and the transmission line, start the transmission line, let the transmission line flow power, and ensure that the power flow of the transmission line fluctuates too much and slowly. After starting the transmission line, use the initial detection device to collect preliminary power flow data of the transmission line, and the end detection device to collect the flow data at the end of the transmission line.

The transmission line is started again for inspection using manual operation within the monitoring platform to ensure the accuracy of the inspection.
