During power transmission, monitoring the operation of cables is one of the main means to ensure normal power transmission. Cable node monitoring systems are usually used to monitor the operation of cables.

[0003] In existing technologies, most cable information acquisition nodes use a fixed wake-up cycle, causing all monitoring nodes to work periodically or remain in a continuous acquisition and reporting state. This makes it impossible to collect node information in a targeted manner, resulting in a large amount of useless data being uploaded and increasing node energy consumption. Summary of the Invention

[0036] The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit the scope of the invention. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the embodiments of the present invention, and not all structures.

[0037] Figure 1 A flowchart of a time-based cable node activation control method provided in an embodiment of the present invention is shown below. Figure 1 As shown, it specifically includes:

[0038] Step S101: Obtain the node configuration table and the set node selection strategy. The node configuration table records the node identifier and node position of each sensor node in the preset area.

[0039] The system includes several key components: a node identifier (which distinguishes each node from the others, and each node has a unique identifier); a node location (which can be the node's GPS position); a sensor node (which can be a high-power node); a node configuration table (which records various node information, including node identifiers and locations within a preset area); and a node selection strategy (which determines the number of sensor nodes to report, and can include fault selection and location selection mechanisms). Before obtaining the node configuration table and setting the node selection strategy, the system needs to configure the node selection strategy, which includes fault selection and location selection mechanisms. In one example, the node configuration table is shown below:

[0040] LVHJJG-C1 (117°12'10E, 39°08'05N) HVHJJG-B1 (117°10'28E, 39°08'27N) SDGHFR-C5 (117°10'31E, 39°05'31N) LVBQJG-D1 (117°10'17E, 39°04'37N) BDHJJG-G1 (117°10'23E, 39°08'31N) ... ...

[0041] Each sensor node has a unique node identifier, and the node location is precisely determined using GPS. The node location of the sensor node with the identifier LVHJJG-C1 is (117°12'10E, 39°08'05N); the node location of the sensor node with the identifier HVHJJG-B1 is (117°10'28E, 39°08'27N); the node location of the sensor node with the identifier SDGHFR-C5 is (117°10'31E, 39°05'31N); the node location of the sensor node with the identifier LVBQJG-D1 is (117°10'17E, 39°04'37N); and the node location of the sensor node with the identifier BDHJJG-G1 is (117°10'23E, 39°08'31N).

[0042] Step S102: Determine the number of nodes to report based on the current time period;

[0043] The node reporting quantity can be the number of nodes that need to report information. When the system identifies the current time period as a set segment threshold, it queries the next time period and its corresponding quantity value, using the pre-set quantity value for the next time period as the node reporting quantity. In one example, if the current time is 5:00, the system identifies 5:00 as one of the set segment thresholds, finds the next time period to be 7:00-10:00, and the value corresponding to this segment is 50. The system uses 50 as the node reporting quantity.

[0044] Step S103: Based on the node selection strategy, select the number of sensor nodes to be reported in the node configuration table, and enable the selected sensor nodes.

[0045] The node selection strategy can be a method for selecting the number of sensor nodes to report, and can include fault selection mechanism and location selection mechanism. When the node selection strategy set in the system is fault selection mechanism, the system will select the number of sensor nodes to report from the node configuration table according to the node location and fault weight, and transmit the node identifier of the selected sensor node to the system. The system will then activate the selected sensor node according to the received node identifier. When the node selection strategy set in the system is location selection mechanism, the system will select the number of sensor nodes to report from the node configuration table according to the node location and location weight, and transmit the node identifier of the selected sensor node to the system. The system will then activate the selected sensor node according to the received node identifier. In one instance, the node selection strategy set within the system is a fault selection mechanism. The number of nodes to be reported is determined to be 50. Based on the number of reported nodes, an equal number of node location groups are determined, totaling 50 groups. Each node location group includes multiple node locations. In each node location group, the sensor node with the highest fault weight is selected, and the selected 50 sensor nodes are activated. In another instance, the node selection strategy set within the system is a location selection mechanism. Based on the location weight of each node, sensor nodes at non-adjacent node locations are selected sequentially from high to low until the number of reported nodes is reached, and the selected sensor nodes are activated.

[0046] As described above, the process involves obtaining a node configuration table and setting a node selection strategy. The node configuration table records the node identifier and location of each sensor node in a preset area. Based on the current time period, the number of nodes to report is determined. Then, based on the node selection strategy, the required number of sensor nodes to report are selected from the node configuration table, and the selected sensor nodes are activated. This solution determines the number of nodes to report based on the current time period, selects the required number of sensor nodes to report based on the obtained node selection strategy, and activates them. This solves the problem in existing technologies where targeted collection of node information is impossible, resulting in a large amount of useless data upload and increased node energy consumption. While ensuring the stability of cable monitoring, it reduces node power consumption, saves transmission bandwidth, reduces the amount of data to be analyzed, and improves work efficiency.

[0047] Figure 2 A flowchart of a method for determining the number of node reports provided in an embodiment of the present invention is shown below. Figure 2 As shown, it specifically includes:

[0048] Step S201: Obtain the node configuration table and the set node selection strategy. The node configuration table records the node identifier and node position of each sensor node in the preset area.

[0049] Step S202: When the current time is the set segment threshold, the quantity value corresponding to the next time period is used as the node reporting quantity.

[0050] The segment threshold can be the boundary point of a time segment set within the system; the quantity value can be a value pre-set for each time segment within the system. When the system identifies the current time point as a segment threshold set within the system, it queries the next time period and the corresponding quantity value for the next time period, and uses the pre-set quantity value for the next time period as the node reporting quantity. In one example, the system sets the segments as 0:00-6:00, 6:00-9:00, and 9:00-12:00, with the segment thresholds being 0:00, 6:00, 9:00, and 12:00. The corresponding quantity values ​​for each segment are 60, 120, and 180. The current time is 6:00, and the system identifies 6:00 as the threshold of the 0:00-6:00 segment, and uses the quantity value of 120 corresponding to the next time period from 0:00-6:00 to 6:00-9:00 as the node reporting quantity.

[0051] Step S203: Based on the node selection strategy, select the number of sensor nodes to be reported in the node configuration table, and enable the selected sensor nodes.

[0052] As described above, the process involves obtaining a node configuration table and setting a node selection strategy. The node configuration table records the node identifier and location of each sensor node in a preset area. Based on the current time period, the number of nodes to report is determined. Then, based on the node selection strategy, the required number of sensor nodes to report are selected from the node configuration table, and the selected sensor nodes are activated. This solution determines the number of nodes to report based on the current time period, selects the required number of sensor nodes to report based on the obtained node selection strategy, and activates them. This solves the problem in existing technologies where targeted collection of node information is impossible, resulting in a large amount of useless data upload and increased node energy consumption. While ensuring the stability of cable monitoring, it reduces node power consumption, saves transmission bandwidth, reduces the amount of data to be analyzed, and improves work efficiency.

[0053] Figure 3 A flowchart of a sensor node method for selecting the number of reported nodes based on a fault selection mechanism, provided in an embodiment of the present invention, is shown below. Figure 3 As shown, it specifically includes:

[0054] Step S301: Obtain the node configuration table and the set node selection strategy. The node configuration table records the node identifier and node position of each sensor node in the preset area.

[0055] Step S302: Determine the number of nodes to report based on the current time period;

[0056] Step S303: When the node selection strategy is a fault selection mechanism, the node selection strategy records the fault weight of each sensor node. Based on the number of reports from the nodes, the same number of node location groups are determined. Each node location group includes multiple node locations. In each node location group, the sensor node with the highest fault weight is selected, and the selected sensor node is activated.

[0057] The fault weight can be a numerical value used to display the fault status of sensor nodes. Initially, each sensor node has the same fault weight, which is automatically adjusted based on the fault status. The fault selection mechanism can be a strategy that selects the number of sensor nodes to report faults based on their fault weights. A node location group can be a combination of multiple evenly divided node locations. After determining the number of reported nodes, the system determines the same number of node location groups based on the reported number. Each node location group contains multiple evenly divided node locations. In each node location group, the sensor node with the highest fault weight is selected, and the node identifier of the selected sensor node is transmitted to the system. The system then activates the selected sensor node according to the received node identifier. In one instance, the system determines that the number of nodes reporting is 50. Based on the number of reported nodes, 50 groups of node locations are determined. The first group of node locations contains ten node locations, which correspond to fault weights of 1, 1, 1, 3, 4, 1, 1, 1, 1, 1 respectively. The sensor node with a fault weight of 4 is selected. Then, 49 sensor nodes are selected from the remaining 49 groups in the same way. The node identifiers of the 50 selected sensor nodes are transmitted to the system. The system activates the selected sensor nodes according to the received node identifiers.

[0058] As described above, the process involves obtaining a node configuration table and setting a node selection strategy. The node configuration table records the node identifier and location of each sensor node in a preset area. Based on the current time period, the number of nodes to report is determined. Then, based on the node selection strategy, the required number of sensor nodes to report are selected from the node configuration table, and the selected sensor nodes are activated. This solution determines the number of nodes to report based on the current time period, selects the required number of sensor nodes to report based on the obtained node selection strategy, and activates them. This solves the problem in existing technologies where targeted collection of node information is impossible, resulting in a large amount of useless data upload and increased node energy consumption. While ensuring the stability of cable monitoring, it reduces node power consumption, saves transmission bandwidth, reduces the amount of data to be analyzed, and improves work efficiency.

[0059] Figure 4 A flowchart illustrating a method for selecting the number of sensor nodes to report based on a location selection mechanism, as provided in this embodiment of the invention, is shown below. Figure 4As shown, it specifically includes:

[0060] Step S401: Obtain the node configuration table and the set node selection strategy. The node configuration table records the node identifier and node position of each sensor node in the preset area.

[0061] Step S402: Determine the number of nodes to report based on the current time period;

[0062] Step S403: When the node selection strategy is a location selection mechanism, the node selection strategy records the location weight of each sensor node. Based on the size of the location weight, sensor nodes at non-adjacent node locations are selected sequentially from high to low until the number of node reports is reached, and the selected sensor nodes are activated.

[0063] The location weight can be a numerical value indicating the importance of a sensor node's location; different sensor node locations have different levels of importance. The location selection mechanism can be a strategy that selects the number of sensor nodes to report based on their location weights. The node selection strategy records the location weight of each sensor node. After the system determines the number of nodes to report, it selects sensor nodes in descending order of their location weights. If a node with a high location weight is adjacent to the next node with the second highest location weight, it is not selected, and the next sensor node with a higher location weight is selected, until the required number of nodes to report is reached. The node identifier of the selected sensor node is then transmitted to the system, and the system activates the selected sensor node according to the received node identifier. In one instance, the system determines that the number of nodes reporting is 5, and the position weights of the nodes from left to right are 1, 1, 9, 8, 1, 5, 1, 7, 2, 8, 1, 4. The selected sensor nodes are those with position weights of 9, 8, 7, 5, 4. The system transmits the node identifiers of the selected sensor nodes to the system. The system activates the selected sensor nodes according to the received node identifiers. Among them, the sensor node with a position weight of 8 is the rightmost sensor node because the leftmost sensor node with a position weight of 8 is adjacent to the sensor node with a position weight of 9.

[0064] As described above, the process involves obtaining a node configuration table and setting a node selection strategy. The node configuration table records the node identifier and location of each sensor node in a preset area. Based on the current time period, the number of nodes to report is determined. Then, based on the node selection strategy, the required number of sensor nodes to report are selected from the node configuration table, and the selected sensor nodes are activated. This solution determines the number of nodes to report based on the current time period, selects the required number of sensor nodes to report based on the obtained node selection strategy, and activates them. This solves the problem in existing technologies where targeted collection of node information is impossible, resulting in a large amount of useless data upload and increased node energy consumption. While ensuring the stability of cable monitoring, it reduces node power consumption, saves transmission bandwidth, reduces the amount of data to be analyzed, and improves work efficiency.
