Description

Technical Field

[0001] The present invention relates to the technical field of intelligent electrical equipment, and in particular to a method and system for reporting data of leakage indicators in a substation. Background Art

[0002] Leakage refers to the phenomenon that current leaks out of the normal circuit path and flows to unexpected conductors or the ground due to insulation damage, aging or other reasons. For example, if the insulation layer of the wire is damaged, the internal conductor will contact the external metal object or the ground, and the current will leak through these unexpected paths.

[0003] With the development of Internet of Things technology, leakage events have begun to be detected and reported through wireless networking. However, for leakage events in substations, the terminal devices for leakage detection are relatively scattered, and it is difficult to quickly report the leakage signals detected by these devices. At the same time, leakage events are prone to cause power outages. When leakage events and power outages occur at the same time, the leakage detection equipment can only rely on its own energy storage device to work for a short time, such as 2 to 3 minutes. At this time, a relatively stable network state is required to report leakage events and power outages in time, which poses a challenge to the networking of leakage detection equipment in substations. Summary of the invention

[0004] In order to at least overcome the above-mentioned deficiencies in the prior art, the purpose of the present application is to provide a method and system for reporting data of a leakage indicator in a substation.

[0005] In a first aspect, an embodiment of the present application provides a method for reporting leakage indicator data in a substation, comprising:

[0006] Dividing the substation equipment into multiple levels according to the signal strength data between the substation equipment; the substation equipment includes at least one substation terminal and multiple leakage indicators;

[0007] Constructing a topological network structure for communication between the equipment in the substation according to the hierarchy;

[0008] When the leakage indicator detects only a leakage signal, the leakage signal is synchronously sent to the substation terminal through a preset link and a preferred link; the preset link is a communication link from the leakage indicator to the substation terminal in the topological network structure; the preferred link is a communication link starting from the leakage indicator and reaching the substation terminal layer by layer along the hierarchy according to the signal strength data between substation devices;

[0009] The station terminal modifies the topological network structure according to the preset link and the preferred link;

[0010] When the leakage indicator detects a leakage signal and a power outage signal at the same time, the leakage signal and the power outage signal are sent to the substation terminal through the preset link in the modified topological network structure.

[0011] When the embodiment of the present application is implemented, it is necessary to divide all the substation equipment into different levels according to the signal strength data between the substation equipment. The reason is that for each leakage indicator, it is necessary to report the detected signal to the substation terminal. If there is a communication barrier between the leakage indicator and the substation terminal, the leakage indicator of the upper layer can be used as a relay for data reporting. The hierarchical relationship generated in the initial state is also conducive to the subsequent generation of the topological network structure. The hierarchy here can correspond to the hierarchical relationship in the topological network structure. After the hierarchical construction is completed, the topological network structure can be constructed according to the hierarchical relationship and the communication between the substation equipment. The topological network structure is the network structure for communication between substation equipment; it is generally a tree structure, the root node is the substation terminal, and the other nodes are leakage indicators.

[0012] In an embodiment of the present application, if the leakage indicator only detects a leakage signal but no power outage occurs, the reporting process of the power outage event can be used to correct the topological network structure; each time only a leakage event occurs, the leakage indicator can be reported through the preset link in the topological network structure, and the data packet after the report will include the signal strength data between the leakage indicator of the relay through which the report passes and the adjacent leakage indicator; at the same time, the leakage indicator will also broadcast the leakage signal, and other leakage indicators in the networking will report the leakage signal to the substation terminal step by step according to the signal strength data. At this time, if the topological network structure is not the optimal solution, the link reported step by step will be different from the preset link in the topological network structure. At this time, the topological network structure can be optimized according to the preferred link generated by the step-by-step reporting to ensure that data can be reported in time with the topological network structure under more urgent conditions. When a leakage event and a power outage event occur at the same time, the leakage indicator can report data according to the optimized topological network structure, which can ensure that when the leakage indicator is synchronously powered off, the leakage signal and the power outage signal can also be reported to the substation terminal in a timely manner. Through the above technical solution, the present application effectively realizes the wireless networking process of leakage detection in the substation, and iteratively optimizes the networking content through the reporting process of the leakage signal, so that when the leakage event and the power outage event occur simultaneously, the corresponding signal can be sent to the substation terminal quickly and efficiently, ensuring the safety of the substation power grid.

[0013] In a possible implementation, dividing the substation equipment into multiple levels according to the signal strength data between substation equipment includes:

[0014] The station area terminal is used as the initial level, and the leakage indicator whose signal strength data with the station area terminal is greater than a preset value is allocated to the next level;

[0015] Allocate the leakage indicator of the unassigned level whose signal strength data with the leakage indicator of the assigned level is greater than a preset value as the next level of the leakage indicator of the assigned level;

[0020] Constructing a topological connection between the topological root node and each topological node in a layer below the topological root node;

[0021] All topological nodes, topological root nodes and topological connections form the topological network structure.

[0022] In a possible implementation, when the leakage indicator detects only a leakage signal, synchronously sending the leakage signal to the station terminal through a preset link and a preferred link includes:

[0023] When the leakage indicator detects only a leakage signal, a link from the leakage indicator to the station terminal is obtained as the preset link according to the topological network structure, and the leakage signal is sent to the station terminal through the preset link;

[0024] The leakage indicator broadcasts the leakage signal, and the leakage indicator on the upper layer that receives the leakage signal determines the signal strength of the received signal, and broadcasts the leakage signal to the terminal in the area where the leakage signal reaches when the signal strength of the received signal meets the preset requirement;

[0025] The link through which the leakage indicator broadcasts the leakage signal and reaches the station terminal is used as the preferred link.

[0026] In a possible implementation, the station terminal correcting the topological network structure according to the preset link and the preferred link includes:

[0027] Acquire all segment signal strength data of the preset link and the preferred link; the segment signal strength data is the signal strength data between two station area devices at adjacent levels;

[0028] The link whose segment signal strength data satisfies the preset requirement and has the best segment signal strength data is taken as the best link;

[0029] The topological network structure is modified according to the optimal link.

[0030] In a possible implementation manner, modifying the topological network structure according to the optimal link includes:

[0031] Searching from the leakage indicator at the starting end of the optimal link along the optimal link to the station terminal at the end end of the optimal link;

[0032] When the leakage indicator of the upper layer connected to any leakage indicator in the optimal link is different from that in the topological network structure, the connection relationship in the topological network structure is modified to the connection relationship in the optimal link.

[0033] In a second aspect, the present application further provides a data reporting system for leakage indicators in a substation, the system comprising a plurality of substation devices; the substation devices comprising at least one substation terminal and a plurality of leakage indicators;

[0034] The station terminal divides the station equipment into multiple levels according to the signal strength data between the station equipment;

[0037] The station terminal modifies the topological network structure according to the preset link and the preferred link;

[0038] When the leakage indicator detects a leakage signal and a power outage signal at the same time, the leakage signal and the power outage signal are sent to the substation terminal through the preset link in the modified topological network structure.

[0060] Please refer to Figure 1, which is a flow chart of a method for reporting leakage indicator data in a substation provided in an embodiment of the present invention. Furthermore, the method for reporting leakage indicator data in a substation may specifically include the contents described in the following steps S1 to S5.

[0062] S2: constructing a topological network structure for communication between the devices in the substation according to the hierarchy;

[0063] S3: When the leakage indicator detects only a leakage signal, the leakage signal is synchronously sent to the substation terminal through a preset link and a preferred link; the preset link is a communication link from the leakage indicator to the substation terminal in the topological network structure; the preferred link is a communication link starting from the leakage indicator and reaching the substation terminal layer by layer along the hierarchy according to the signal strength data between substation devices;

[0064] S4: The station terminal modifies the topological network structure according to the preset link and the preferred link;

[0065] S5: When the leakage indicator detects a leakage signal and a power outage signal at the same time, the leakage signal and the power outage signal are sent to the substation terminal through the preset link in the modified topology network structure.

[0066] When the embodiment of the present application is implemented, it is necessary to divide all the substation equipment into different levels according to the signal strength data between the substation equipment. The reason is that for each leakage indicator, it is necessary to report the detected signal to the substation terminal. If there is a communication barrier between the leakage indicator and the substation terminal, the leakage indicator of the upper layer can be used as a relay for data reporting. The hierarchical relationship generated in the initial state is also conducive to the subsequent generation of the topological network structure. The hierarchy here can correspond to the hierarchical relationship in the topological network structure. After the hierarchical construction is completed, the topological network structure can be constructed according to the hierarchical relationship and the communication between the substation equipment. The topological network structure is the network structure for communication between substation equipment; it is generally a tree structure, the root node is the substation terminal, and the other nodes are leakage indicators.

[0067] In an embodiment of the present application, if the leakage indicator only detects a leakage signal but no power outage occurs, the reporting process of the power outage event can be used to correct the topological network structure; each time only a leakage event occurs, the leakage indicator can be reported through the preset link in the topological network structure, and the data packet after the report will include the signal strength data between the leakage indicator of the relay through which the report passes and the adjacent leakage indicator; at the same time, the leakage indicator will also broadcast the leakage signal, and other leakage indicators in the networking will report the leakage signal to the substation terminal step by step according to the signal strength data. At this time, if the topological network structure is not the optimal solution, the link reported step by step will be different from the preset link in the topological network structure. At this time, the topological network structure can be optimized according to the preferred link generated by the step-by-step reporting to ensure that data can be reported in time with the topological network structure under more urgent conditions. When a leakage event and a power outage event occur at the same time, the leakage indicator can report data according to the optimized topological network structure, which can ensure that when the leakage indicator is synchronously powered off, the leakage signal and the power outage signal can also be reported to the substation terminal in a timely manner. Through the above technical solution, the present application effectively realizes the wireless networking process of leakage detection in the substation, and iteratively optimizes the networking content through the reporting process of the leakage signal, so that when the leakage event and the power outage event occur simultaneously, the corresponding signal can be sent to the substation terminal quickly and efficiently, ensuring the safety of the substation power grid.

[0068] In a possible implementation, dividing the substation equipment into multiple levels according to the signal strength data between substation equipment includes:

[0069] The station area terminal is used as the initial level, and the leakage indicator whose signal strength data with the station area terminal is greater than a preset value is allocated to the next level;

[0070] Allocate the leakage indicator of the unassigned level whose signal strength data with the leakage indicator of the assigned level is greater than a preset value as the next level of the leakage indicator of the assigned level;

[0071] The leakage indicator allocation is repeated until all the equipment in the area are allocated a level.

[0072] When the embodiment of the present application is implemented, when dividing the levels, it is necessary to take the substation terminal that receives all leakage signals and power outage signals as the first level, and at the same time, the leakage indicators all broadcast signals. The substation terminal can divide the leakage indicators in the next level of the substation terminal according to the signal strength value corresponding to the received signal, that is, the leakage indicators of the second level; and the leakage indicators in the second level filter the leakage indicators of the third level corresponding to the signal strength value of the monitored signal, and so on, all the leakage indicators are assigned to the corresponding levels.

[0073] In a possible implementation, constructing a topological network structure for communication between the substation devices according to the hierarchy includes:

[0074] All the leakage indicators are used as topological nodes, and the substation terminal is used as a topological root node;

[0075] Constructing a topological connection between each of the topological nodes and a parent node corresponding to the topological node; the parent node is a topological node in an upper layer having the best signal strength data with the topological node;

[0076] Constructing a topological connection between the topological root node and each topological node in a layer below the topological root node;

[0077] All topological nodes, topological root nodes and topological connections form the topological network structure.

[0078] When the embodiment of the present application is implemented, when constructing the communication topology network, all leakage indicators need to be taken as topology nodes first, and the substation terminal needs to be taken as the topology root node; when constructing the connection between the topology nodes, it is possible to adopt a method of searching upward from the lowest layer, that is, the leaf node; the topology node to which each topology node is connected upward is the topology node with the best communication status, so as to ensure that the initially generated topology network structure is the optimal communication topology structure under the status of the current substation.

[0079] In a possible implementation, when the leakage indicator detects only a leakage signal, synchronously sending the leakage signal to the station terminal through a preset link and a preferred link includes:

[0080] When the leakage indicator detects only a leakage signal, a link from the leakage indicator to the station terminal is obtained as the preset link according to the topological network structure, and the leakage signal is sent to the station terminal through the preset link;

[0081] The leakage indicator broadcasts the leakage signal, and the leakage indicator on the upper layer that receives the leakage signal determines the signal strength of the received signal, and broadcasts the leakage signal to the terminal in the area where the leakage signal reaches when the signal strength of the received signal meets the preset requirement;

[0082] The link through which the leakage indicator broadcasts the leakage signal and reaches the station terminal is used as the preferred link.

[0083] When the embodiment of the present application is implemented, when the leakage indicator detects only a leakage signal, it is necessary to send a signal to the station terminal through a preset link and a preferred link at the same time, wherein the preset link is a link generated based on the topological network structure, and the preferred link is a possible better link screened out by the leakage indicator through layer-by-layer broadcasting. It should be understood that the generation of the topological network structure is generated from the bottom up, so if the communication status between the leakage indicators does not change, the preferred link should be the same as the preset link, and only when the communication status changes, a better preferred link will be screened out, and the reason for the change in communication status may be various reasons such as changes in antenna position and shape, and new obstacles. When the leakage indicator broadcasts the leakage signal, regardless of whether the leakage signal is generated by the leakage indicator, the corresponding upper layer leakage indicator that meets the signal strength requirements will broadcast again, so multiple preferred links may be generated in the propagation of a leakage signal.

[0084] In a possible implementation, the station terminal correcting the topological network structure according to the preset link and the preferred link includes:

[0085] Acquire all segment signal strength data of the preset link and the preferred link; the segment signal strength data is the signal strength data between two station area devices at adjacent levels;

[0086] The link whose segment signal strength data satisfies the preset requirement and has the best segment signal strength data is taken as the best link;

[0087] The topological network structure is modified according to the optimal link.

[0088] When the embodiment of the present application is implemented, since there may be multiple preferred links in the above embodiment, in order to select the preferred links and the preset links, the embodiment of the present application adopts the best segmented signal strength data for selection. Since the corresponding hierarchical relationship has been set up before, the number of segmented signal strength data of each preset link and the preferred link is the same. When selecting the optimal link, first, the optimal link needs to satisfy that each segmented signal strength data meets the most basic preset requirements. At the same time, the optimal link should have the most robust segmented link data. After multiple line corrections in this way, the signal will slowly concentrate on this most robust segmented link for data transmission, thereby more effectively ensuring the quality of data transmission.

[0089] When the embodiment of the present application is implemented, if there is more than one link with optimal segmented signal strength data, the next level segmented signal strength data of these links are compared, and the link with the best next level segmented signal strength data is selected as the optimal link; similarly, if the only optimal link cannot be screened out, the next level segmented signal strength data comparison is performed again until the only optimal link can be screened out.

[0090] In a possible implementation manner, modifying the topological network structure according to the optimal link includes:

[0091] Searching from the leakage indicator at the starting end of the optimal link along the optimal link to the station terminal at the end end of the optimal link;

[0092] When the leakage indicator of the upper layer connected to any leakage indicator in the optimal link is different from that in the topological network structure, the connection relationship in the topological network structure is modified to the connection relationship in the optimal link.

[0093] When the embodiment of the present application is implemented, the method of correcting the topological network structure is similar to the networking method, both of which start from the starting end of a link and perform topological correction upward, that is, the entire link from the leakage indicator to the final substation terminal in the topological network structure is corrected to the optimal link.

[0094] For examples, see Figure 2 , shows a schematic diagram of the layout of the substation equipment, where the substation terminal is located at the initial level, and the subsequent dotted line part represents the levels set in sequence, and the circles represented by numbers are different leakage indicators. In this example, the substation has one substation terminal and 10 leakage indicators. In the hierarchical stage, the leakage indicators No. 1 and No. 2 have signal strength data with the substation terminal greater than the preset value, and the leakage indicators No. 3 and No. 4 have signal strength data with leakage indicators No. 1 and No. 2 greater than the preset value, and the hierarchical process is realized by analogy. Then the networking operation is carried out, and the final topological structure can be seen in Figure 3 .

[0095] When leakage indicator No. 9 only generates leakage signal, its preset link is 9-6-4-1, and it generates a preferred link 9-7-3-1. At this time, the two links are optimized and it is found that the best segment signal strength appears in 3-1. Therefore, the link relationship in the topological network structure is modified to Figure 3 The dotted line relationship in is corrected.

[0096] In a second aspect, the present application further provides a data reporting system for leakage indicators in a substation, the system comprising a plurality of substation devices; the substation devices comprising at least one substation terminal and a plurality of leakage indicators;

[0097] The station terminal divides the station equipment into multiple levels according to the signal strength data between the station equipment;

[0098] The station terminal constructs a topological network structure for communication between the station devices according to the hierarchy;

[0099] When the leakage indicator detects only a leakage signal, the leakage signal is synchronously sent to the substation terminal through a preset link and a preferred link; the preset link is a communication link from the leakage indicator to the substation terminal in the topological network structure; the preferred link is a communication link starting from the leakage indicator and reaching the substation terminal layer by layer along the hierarchy according to the signal strength data between substation devices;

[0100] The station terminal modifies the topological network structure according to the preset link and the preferred link;

[0101] When the leakage indicator detects a leakage signal and a power outage signal at the same time, the leakage signal and the power outage signal are sent to the substation terminal through the preset link in the modified topological network structure.

[0102] In the embodiment of the present application, the hierarchical division and the construction of the topological network structure are both implemented by the substation terminal with higher computing power. The substation terminal will send the divided hierarchical relationship and the position of each leakage indicator in the topological network structure to the corresponding leakage indicator. When the leakage indicator sends or forwards information, it only needs to add its own address and the signal strength corresponding to the forwarded information in the data packet to realize the display of the complete link in the substation terminal.

[0103] In a possible implementation, the station terminal is further configured as follows:

[0104] The station area terminal is used as the initial level, and the leakage indicator whose signal strength data with the station area terminal is greater than a preset value is allocated to the next level;

[0105] Allocate the leakage indicator of the unassigned level whose signal strength data with the leakage indicator of the assigned level is greater than a preset value as the next level of the leakage indicator of the assigned level;

[0106] The leakage indicator allocation is repeated until all the equipment in the area are allocated a level.

[0107] In a possible implementation, the station terminal is further configured as follows:

[0108] All the leakage indicators are used as topological nodes, and the substation terminal is used as a topological root node;

[0110] Constructing a topological connection between the topological root node and each topological node in a layer below the topological root node;

[0111] All topological nodes, topological root nodes and topological connections form the topological network structure.

[0112] In a possible implementation, the leakage indicator is further configured as follows:

[0113] When the leakage indicator detects only a leakage signal, a link from the leakage indicator to the station terminal is obtained as the preset link according to the topological network structure, and the leakage signal is sent to the station terminal through the preset link;

[0114] The leakage indicator broadcasts the leakage signal, and the leakage indicator on the upper layer that receives the leakage signal determines the signal strength of the received signal, and broadcasts the leakage signal to the terminal in the area where the leakage signal reaches when the signal strength of the received signal meets the preset requirement;

[0115] The link through which the leakage indicator broadcasts the leakage signal and reaches the station terminal is used as the preferred link.
