Abstract
Description
Technical Field
[0001] The present application belongs to the technical field of power maintenance equipment, and specifically, relates to a cable network maintenance test method, system and equipment. Background Art
[0002] Cable is an electrical energy or signal transmission device, usually composed of several or several groups of wires. Cables include power cables, control cables, compensation cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, etc. They are all composed of single or multiple wires and insulation layers, and are used to connect circuits, electrical appliances, etc.
[0003] When the cable is in use, it needs to be maintained regularly. During maintenance, the staff needs to climb the pole tower, then walk on the overhead wires and inspect the overhead wires, and then maintain the aging and broken parts of the surface. However, this method relying on manual inspection will consume more manpower, the quality of the inspection effect is not stable enough, it is difficult to determine the fault area and the maintenance efficiency is low. Summary of the invention
[0004] In order to solve the above problems and technical defects, the present application adopts the following technical solution, a cable network maintenance test method, comprising the following steps:
[0005] Step 1: Use a cable network tester with multiple test ports to monitor and collect data from the cable to be tested with multiple test points evenly set, and obtain multiple groups of test data of the cable to be tested;
[0006] Step 2, segment each group of test data according to the test point to obtain multiple groups of multi-segment test data, and determine whether a breakpoint fault occurs in the cable to be tested according to the multiple groups of multi-segment test data. If a breakpoint fault occurs, locate the breakpoint fault;
[0007] Step 3: If there is no breakpoint fault, obtain the cable to be tested and a reference cable of the same model as the cable to be tested, use a cable network tester to test the reference cable, and obtain reference change data;
[0008] Step 4: Calculate and process the test data according to the reference change data, and determine whether the cable to be tested needs maintenance based on the calculation result. If so, maintain the cable to be tested.
[0009] Preferably, the testing process of testing the cable to be tested is as follows:
[0010] Each test port of the cable network tester is connected to a test probe, each test port is assigned a port number, and each test point is assigned a test point number;
[0011] Connect the test probe to the test point on the cable to be tested, and bind the port number and the test point number connected to it;
[0012] Each test port outputs a power-on test according to a preset sequence, and other test ports monitor and collect various data of the test points through test probes to obtain multiple groups of test data of the cable to be tested.
[0013] Furthermore, the process of judging and locating the breakpoint fault is as follows:
[0014] Preset a breakpoint threshold, compare each segment of test data with the breakpoint threshold, and if the target segment test data is less than the breakpoint threshold, the target segment test data is judged to be invalid and a breakpoint fault occurs in the target segment;
[0015] When a breakpoint fault occurs in the target group test data, invalid segment test data is extracted from the target group test data, and then the segment test data with the smallest test point number difference is selected;
[0016] The breakpoint fault is located according to the test point number and the test port number of the selected segment test data.
[0017] Furthermore, the segmentation process is to split each group of test data into multiple segments of test data corresponding to the test points according to the number and position relationship of the test points, and each segment of test data corresponds to a test port number and two test point numbers.
[0018] Furthermore, the process of calculating and processing the test data is as follows:
[0019] Obtain reference data of each test point of each set of test data according to the reference change data and the initial value output when each test port is powered on for testing;
[0020] The reference data of each test point of each set of test data is maintained and calculated with the test data obtained by actual testing and monitoring to obtain maintenance calculation results, and whether the cable to be tested needs maintenance is determined based on the maintenance calculation results.
[0021] Further, the test of the reference cable is to use three test probes on the cable network tester to connect and power on the two ends and the center point of the reference cable to obtain reference initial data, and then calculate according to the length of the reference cable and the distance between two adjacent test points on the cable to be tested to obtain reference change data between the two test points;
[0022] The length of the reference cable is greater than the distance between two adjacent test points on the cable to be tested.
[0023] Furthermore, the maintenance calculation process is as follows:
[0024] First, calculate the deviation value of each set of test data from its corresponding reference data. The deviation value calculation formula is as follows:
[0025] N i =Σ j＝1 [(Q ij -T ij ) 2 *e i ]
[0026] Among them, N i is the deviation value of the i-th group of test data, Q ij is the reference data of the jth test point in the i-th test data set, T ij is the test data actually monitored at the jth test point in the i-th test data group, e i is the test coefficient of the i-th group of test data;
[0027] The maintenance value of the entire cable to be tested is calculated based on the deviation value of each set of test data. The maintenance value calculation formula is as follows:
[0028] M=Σ i＝1 [(N i -K) 2 / (N i-1 -K) 2 ]
[0029] Where M is the maintenance value of the entire cable to be tested, K is the stability factor, and N0 is equal to 0;
[0030] A maintenance threshold is preset, and the maintenance value of the entire cable to be tested is compared with the maintenance threshold. If the maintenance value is less than the maintenance threshold, it is determined that the cable to be tested has no maintenance requirement; otherwise, it is determined that the cable to be tested has maintenance requirement.
[0031] A cable network maintenance and testing system, comprising:
[0032] An interface probe module is used to connect the test port of the cable network tester to the cable to be tested;
[0033] A power-on test module is used to perform a power-on test on the test points of the cable to be tested;
[0034] The monitoring and acquisition module is used to monitor and collect test points of the cable to be tested and obtain test data for each power-on test;
[0035] A fault judgment module is used to judge whether a breakpoint fault occurs in the cable to be tested according to the test data of the power-on test, and if so, locate the breakpoint fault;
[0036] A maintenance judgment module is used to calculate and process the test data to determine whether the cable to be tested needs maintenance. If so, the cable to be tested needs maintenance.
[0037] The report generation module is used to generate and export reports based on power-on test data, fault judgment results, fault location results, and maintenance judgment results.
[0038] An electronic device comprises a memory, a processor and a computer program stored in the memory and executable on the processor, wherein the processor implements the steps of the cable network maintenance test method as described above when executing the program.
[0039] A computer-readable storage medium stores a computer program, which implements the steps of the cable network maintenance test method as described above when executed by a processor.

[0048] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.
[0049] Example 1
[0050] like Figure 1 As shown, it can be known from the above description that in this example, a cable network maintenance test method includes the following steps:
[0051] Use a cable network tester to test the cable to be tested and obtain test data of the cable to be tested;
[0052] The test process for testing the cable to be tested is as follows:
[0053] The cable network tester is equipped with multiple test ports, each of which is connected to a test probe and has a port number.
[0054] Multiple test points are evenly set on the cable to be tested, and each test point is assigned a test point number;
[0055] Connect the test probe to the test point on the cable to be tested, and bind the port number and the test point number connected to it;
[0056] Each test port outputs a power-on test according to a preset sequence, and other test ports monitor and collect various data of the test points through test probes to obtain multiple groups of test data of the cable to be tested.
[0057] Each set of test data corresponds to a port number.
[0058] If the cable network tester has 20 test ports, the ports are numbered 1-20, and there are 30 test points, the test points are numbered 1-30;
[0059] Then the first cable network tester first tests the test points with port numbers 1-20, and obtains 20 groups of test data. Each group of test data corresponds to a port number. For example, the 19th group of test data obtained by testing the test point number 19 corresponds to the port number 19.
[0060] The second cable network tester tests the test points with port numbers 21-30. However, in order to avoid missing the cable anomaly between test point 20 and test point 21, the test ports 1-11 of the second cable network tester are bound to test points 20-30 for testing, and 11 groups of test data are obtained. Each group of test data corresponds to a port number. For example, the test point number 20 is tested to obtain the first group of test data corresponding to port number 1, and the test point number 30 is tested to obtain the 11th group of test data corresponding to port number 11.
[0061] Determine whether a breakpoint fault occurs in the cable to be tested according to the test data of the cable to be tested, and locate the breakpoint fault if there is a breakpoint fault;
[0062] The process of judging and locating breakpoint faults is as follows:
[0063] Each group of test data is segmented according to the test points to obtain multiple groups and multiple segments of test data;
[0064] Preset a breakpoint threshold, compare each segment of test data with the breakpoint threshold, and if the target segment test data is less than the breakpoint threshold, the target segment test data is judged to be invalid and a breakpoint fault occurs in the target segment;
[0065] When a breakpoint fault occurs in the target group test data, invalid segment test data is extracted from the target group test data, and then the segment test data with the smallest test point number difference is selected;
[0066] The breakpoint fault is located according to the test point number and the test port number of the selected segment test data.
[0067] Segment processing is to split each group of test data into multiple segments of test data corresponding to the test points according to the number and position relationship of the test points, and each segment of test data corresponds to a test port number and two test point numbers.
[0068] For example, in the test of the second cable network tester mentioned above, the 11th group of test data corresponds to port number 11 and test point number 30. The 11th group of test data is the test data monitored by the other ten test ports after the 11th test port is powered on for testing. Then the data monitored by test point 29 is the data of segments 29-30 of the 11th group, the data monitored by test point 28 is the data of segments 28-30 of the 11th group, ..., the data monitored by test point 20 is the data of segments 20-30 of the 11th group, and the 11th group of test data has a total of 10 segments.
[0069] If a breakpoint occurs between test point 28 and test point 29, then in the 11th group of test data, test point 29 can monitor the test current data, but test point 28 and other test points cannot monitor the test current data or the current is so small that it can be ignored, and the monitored current value is less than the breakpoint threshold. Therefore, in the 11th group of test data, only the detection data of test point 29 is valid, and other segment test data are invalid. At this time, the invalid segment test data is extracted and selected, and the segment test data with the smallest test point number difference is the 11th group 28-30 segment test data. At the same time, test point 30 is the test current output by port 11, and test point 28 is the monitoring receiving point. The breakpoint fault is around test point 28 and will not cross test point 27 and test point 29. Because the segment test data is 28-30, the breakpoint fault is between test point 28 and test point 30, so the breakpoint fault is between test point 28 and test point 29.
[0070] Similarly, in the 9th test data, after the 28th test point receives the test current output by the 9th test port, the 29th test point and the 30th test point cannot monitor the test current data. Therefore, the detection data of the 29th test point and the 30th test point in the 9th test data are invalid.
[0071] This is the case where one breakpoint occurs. If multiple breakpoints occur, multiple judgments are performed. For example, the 11th group of test data can determine that a breakpoint fault has occurred, and the breakpoint fault location is between test points 28 and 29. However, if there is a breakpoint between test points 25 and 26, the 11th group of test data cannot be judged. Therefore, other groups of test data are needed to judge whether the entire cable to be tested has a breakpoint fault, as well as the location of each breakpoint fault.
[0072] If there is no breakpoint fault, the test data is calculated and processed, and it is determined whether the tested cable needs maintenance according to the calculation result. If so, the tested cable is maintained.
[0073] The process of calculating and processing the test data is as follows:
[0074] Obtain a cable to be tested and a reference cable of the same model as the cable to be tested, use a cable network tester to test the reference cable, and obtain reference change data;
[0075] Obtain reference data of each test point of each set of test data according to the reference change data and the initial value output when each test port is powered on for testing;
[0076] The reference data of each test point of each set of test data is maintained and calculated with the test data obtained by actual testing and monitoring to obtain maintenance calculation results, and whether the cable to be tested needs maintenance is determined based on the maintenance calculation results.
[0077] The maintenance calculation process is as follows:
[0078] First, calculate the deviation value of each set of test data from its corresponding reference data. The deviation value calculation formula is as follows:
[0079] N i =Σ j＝1 [(Q ij -T ij ) 2 *e i ]
[0080] Among them, Ni is the deviation value of the i-th group of test data, Qij is the reference data of the j-th test point in the i-th group of test data, Tij is the test data actually monitored by the j-th test point in the i-th group of test data, and e i is the test coefficient of the i-th group of test data;
[0081] The maintenance value of the entire cable to be tested is calculated based on the deviation value of each set of test data. The maintenance value calculation formula is as follows:
[0082] M=Σ i＝1 [(N i -K) 2 / (N i-1 -K) 2 ]
[0083] Where M is the maintenance value of the entire cable to be tested, K is the stability factor, and N0 is equal to 0;
[0084] A maintenance threshold is preset, and the maintenance value of the entire cable to be tested is compared with the maintenance threshold. If the maintenance value is less than the maintenance threshold, it is determined that the cable to be tested has no maintenance requirement; otherwise, it is determined that the cable to be tested has maintenance requirement.
[0085] The reference cable is tested by connecting the three test probes on the cable network tester to the two ends and the center of the reference cable and conducting a power-on test to obtain the reference initial data. The reference change data between the two test points is then calculated based on the length of the reference cable and the distance between two adjacent test points on the cable to be tested.
[0086] The length of the reference cable is greater than the distance between two adjacent test points on the cable to be tested.
[0087] The reference cable is a cable whose insulation, conductivity, cable sheath thickness, core diameter, and resistance value all meet the use standards. Therefore, when testing the reference cable, the monitored voltage value, current value, voltage change value, current change value, temperature value, and temperature change value are all standard values. These standard values are used as reference change data.
[0088] For example, if the current change value in the reference change data is -1, the current will decrease by one unit at every test point. For example, the current is the 5th group of test data, and the corresponding test port 5 outputs the test current through the test point 24. The initial test current unit is 30. According to the reference data, the reference current monitored by the test points 23 and 22 is 29, and the reference current monitored by the test points 22 and 25 is 28.
