Description

Technical Field

[0001] This invention relates to the field of power safety technology, and in particular to a dynamic control method, system, equipment and storage medium for grounding wires of overhead lines. Background Technology

[0002] During maintenance operations in the power industry, it is necessary to install a large number of temporary grounding wires to prevent electrostatic induction electric shock or accidental closing of circuits caused by nearby live conductors, so as to ensure the safety of equipment operation and personnel operations.

[0003] Currently, in substation maintenance operations, by setting up fixed connection points at the work site and installing five-proof locks at these points, and pre-setting the grounding wire connection sequence in the grounding wire management device, combined with the five-proof switching operation ticket and computer key, the grounding wires can be connected to the corresponding fixed connection points step by step on-site. This effectively prevents the misconnection or omission of temporary grounding wires. However, in the operation scenarios of overhead distribution lines, most of the work is done in the field, and the overhead lines have long spans, numerous points, wide areas, short maintenance operation windows, and many high-risk and complex operation situations. Therefore, on-site work is often not feasible. There are no fixed grounding connection points, and no fixed power supply for welding grounding piles. Especially for the maintenance of long-distance overhead lines, when multiple shifts need to participate, in order to improve work efficiency, the operators need to respond flexibly and quickly according to the actual situation. The connection of temporary grounding wires cannot be done in the same way as substation maintenance, where the grounding wire number is pre-set and accurately connected to the fixed connection point. Therefore, the connection or removal of temporary grounding wires for distribution overhead lines cannot adopt the fixed grounding wire management method of substation maintenance, and can only rely on manual inspection and counting.

[0004] Given that the connection and removal of temporary grounding wires for overhead power distribution lines still rely on manual methods, and there is a lack of effective technical means for the use and management of grounding wires, as well as a lack of corresponding records, monitoring, and closed-loop electronic process management for the entire operation of taking, connecting, and removing temporary grounding wires, serious operational accidents often occur due to misconnection or omission of temporary grounding wires. These accidents pose a serious threat to the personal safety of maintenance personnel and the asset safety of the power grid. In order to solve the above problems, there is an urgent need for a flexible and well-managed control method for temporary grounding wires of overhead power lines. Summary of the Invention

[0043] The second aspect of the present invention provides an overhead line grounding wire management and control system, the overhead line grounding wire management and control system including a server, a grounding wire management device, a mobile terminal, multiple sets of grounding wires stored in the grounding wire management device, and a grounding wire lock that locks the grounding end and the connection end of the grounding wire;

[0044] The server is configured to receive maintenance switching operation tickets sent by the mobile terminal; when the maintenance switching operation ticket includes a target grounding wire connection operation task, control the grounding wire management device to unlock at least a portion of the grounding wires; after the target grounding wire connection operation task is completed, generate first grounding wire information dynamically bound to the target grounding wire connection operation task, and update the maintenance switching operation ticket according to the first grounding wire information; receive a power restoration switching operation ticket sent by the mobile terminal that is associated with and mapped to the updated maintenance switching operation ticket, generate second grounding wire information according to the target grounding wire removal operation task included in the power restoration switching operation ticket; and determine the unlocking information of the target grounding wire to be removed according to the second grounding wire information.

[0050] A fourth aspect of the present invention provides a computer-readable storage medium storing a computer program that, when executed by a processor, implements the above-described dynamic control method for overhead line grounding wires.

[0051] In the technical solution provided by this invention, when connecting a grounding wire, a maintenance switching operation ticket sent by the mobile terminal is received. When the maintenance switching operation ticket includes a target grounding wire connection operation task, at least a portion of the grounding wires in the grounding wire management device are identified as candidate grounding wires, and the lock on the candidate grounding wires is released. At least one group of the candidate grounding wires is arbitrarily selected as the target grounding wire to be connected, and the grounding wire lock corresponding to the target grounding wire is unlocked to authorize connection. After the target grounding wire connection operation task is completed, first grounding information dynamically bound to the target grounding wire connection operation task is generated, and according to the... The first ground wire information updates the maintenance switching operation ticket; when the ground wire is removed, the system receives a power restoration switching operation ticket sent by the mobile terminal that is associated with and mapped to the updated maintenance switching operation ticket, and generates second ground wire information based on the target ground wire removal operation task contained in the power restoration switching operation ticket, wherein the second ground wire information includes at least a portion of the first ground wire information; based on the second ground wire information, the system determines the unlocking information of the target ground wire to be removed; the system reads the ground wire lock code value corresponding to the target ground wire to be removed, and when the read code value is consistent with the unlocking information, the system controls the ground wire lock to unlock and instructs removal to be performed. In this embodiment of the invention, a special type of grounding lock is used to lock the grounding end and the connection end of the corresponding grounding wire and store them in the grounding wire management device. When a grounding wire connection operation task is received, the server controls the grounding wire management device to immediately release the lock on at least a portion of the grounding wires so that the grounding wires and grounding locks can be used arbitrarily as a whole. By not binding the grounding wires with the maintenance switching operation ticket and operation task in advance, the grounding wires can be used arbitrarily, and the grounding locks can be opened arbitrarily. This reduces the trouble caused by the inability to adjust in time when a fault occurs during operation after the grounding wire connection sequence and position are preset, which affects the overall operation progress. During connection, the arbitrarily selected grounding wire is connected to the transmission line. After the connection is completed, the system can automatically bind the first grounding information of the grounding wire with the target grounding wire connection operation task on site and automatically close the lock. The system, without human intervention, enables real-time matching and flexible dynamic management of grounding wire connections. During removal, the system determines the grounding wire removal task included in the power restoration operation ticket within the scope of the maintenance switching operation ticket and identifies the corresponding second grounding wire information. The unlocking information of the target grounding wire to be removed is determined through the second grounding wire information. Furthermore, the system controls the unlocking of the grounding lock and instructs removal by reading and comparing the grounding lock code value corresponding to the target grounding wire to be removed. The system effectively ensures the correct removal of temporary grounding wires, and the operation nodes do not require frequent authorization throughout the process, reducing the inconvenience caused by remote authorization in outdoor scenarios with overhead lines. It achieves closed-loop management of the entire process of grounding wire access, connection, and removal, which not only improves the efficiency of overhead line maintenance operations through flexible operation but also ensures operational safety through orderly management.

[0064] It should be noted that, as an example and not a limitation, the data transmission method (e.g., server data transmission) between the various devices / equipment in the dynamic management method for overhead line grounding wires in this embodiment of the invention adopts a wireless communication method. The wireless communication method includes, but is not limited to, Bluetooth (BT), ZigBee Technology (ZigBee), LoRa, 2.4GHz Wireless Technology (2.4G), 433MHz wireless communication, fourth-generation mobile communication 4G, General Packet Radio Service (GPRS), and Narrow Band Internet of Things (NB-IoT).

[0065] For easier understanding, please refer to Figure 1 , Figure 1This is a schematic diagram of an overhead line grounding wire management system provided in an embodiment of the present invention. The overhead line grounding wire management system 100 includes a server 110, a mobile terminal 120, multiple sets of grounding wires 130 stored in a grounding wire management device 150, and a grounding wire lock 140 that locks the grounding end and the connection end of the grounding wires. The server 110 is used to receive maintenance switching operation tickets sent by the mobile terminal 120. When the maintenance switching operation ticket includes a target grounding wire connection operation task, the server controls the grounding wire management device 150 to release the lock on at least a portion of the grounding wires. After the target grounding wire connection operation task is completed, the server generates first grounding wire information dynamically bound to the target grounding wire connection operation task and updates the maintenance switching operation ticket according to the first grounding wire information. The server also receives the updated maintenance switching operation ticket sent by the mobile terminal 120. The system generates second ground wire information based on the target ground wire removal operation task contained in the power restoration and switching operation ticket; it determines the unlocking information of the target ground wire to be removed based on the second ground wire information; the ground wire management device 150 is used to lock and store the multiple sets of ground wires 130 and the corresponding ground wire locks 140, and unlocks at least a portion of the ground wires under the control of the server 110; the mobile terminal 120 is used to generate and send maintenance switching operation tickets / power restoration switching operation tickets, and control the unlocking / locking of the ground wire locks 140; the ground wires 130 are used for maintenance personnel to dynamically access / remove to perform target ground wire connection operation tasks / target ground wire removal operation tasks; the ground wire locks 140 are used to lock the corresponding ground wires 130 before / after the target ground wire connection operation task is executed.

[0066] The overhead line grounding wire management system 100 is used to realize a dynamic management method for overhead line grounding wires. During connection, a maintenance switching operation ticket containing the target grounding wire connection operation task is sent via a mobile terminal 120. The server 110 controls the grounding wire management device 150 to unlock at least a portion of the grounding wires 130. At least one group of grounding wires that have been unlocked can be arbitrarily selected as the target grounding wire and the corresponding grounding wire lock 140 is unlocked. The first grounding wire information is dynamically bound to the target grounding wire connection operation task and written into the maintenance switching operation ticket. By not pre-binding the grounding wire with the maintenance switching operation ticket and operation task, the grounding wire can be used arbitrarily and the grounding wire lock can be opened arbitrarily. This reduces the trouble caused by the inability to adjust in time when a fault occurs during operation after the grounding wire connection sequence and position are preset, which affects the overall operation progress. After the connection is completed, when the grounding end of the grounding wire is reliably grounded, the grounding wire lock is triggered to close. The system locks and reports the grounding lock code value. At this time, the system can automatically bind the first grounding information of the grounding wire with the target grounding wire connection operation task on site, and automatically associate them to realize the real-time matching and flexible dynamic management of the grounding wire on site. When removing the grounding wire, the system determines the grounding wire removal operation task included in the power restoration operation ticket within the scope of the maintenance switching operation ticket and determines the corresponding second grounding information. The unlocking information of the target grounding wire to be removed is determined by the second grounding information. The system also controls the grounding lock to unlock and instructs the removal by reading and comparing the grounding lock code value corresponding to the target grounding wire to be removed. In addition, each operation node does not need to be frequently authorized, which reduces the trouble caused by the inconvenience of remote authorization in the outdoor scenario of overhead lines. It realizes the closed-loop management of the entire process of grounding wire use, connection and removal, which not only improves the efficiency of overhead line maintenance operations with flexible operation, but also ensures the safety of operation with orderly management.

[0067] For ease of understanding, the specific process of the embodiments of the present invention is described below. Please refer to [link / reference]. Figure 2 , Figure 2 This is a schematic diagram of a dynamic management and control method for overhead line grounding wires provided in an embodiment of the present invention. The dynamic management and control method for overhead line grounding wires in this embodiment is applied to an overhead line grounding wire management and control system 100. One embodiment of the dynamic management and control method for overhead line grounding wires in this embodiment includes:

[0068] 201. Receive maintenance switching operation tickets sent by mobile terminals. When the maintenance switching operation ticket includes a target grounding wire connection operation task, identify at least a portion of the grounding wires in the grounding wire management device as candidate grounding wires and unlock the candidate grounding wires.

[0069] Among them, mobile terminal 120 refers to a convenient mobile device operated by maintenance personnel, such as a mobile phone or tablet. The overhead line grounding wire management system may include one or more mobile terminals. One shift of maintenance personnel can hold one mobile terminal corresponding to one switching operation ticket, or multiple shifts of maintenance personnel can hold multiple mobile terminals corresponding to multiple switching operation tickets.

[0070] Before the maintenance operation begins, the mobile terminal 120 sends the generated maintenance switching operation ticket to the server 110. The server determines whether the obtained maintenance switching operation ticket contains a temporary grounding wire operation item. If the determination result is that it contains a temporary grounding wire operation item, it issues an unlocking control command to the grounding wire management device 150. According to the received unlocking control command, the grounding wire management device simultaneously unlocks at least a portion of the grounding wires 130 stored in the grounding wire management device that correspond to the grounding wire connection operation task. After the corresponding number of grounding wires are unlocked, the grounding locks 140 set corresponding to the grounding wires are also released from the grounding wire management device. The grounding locks are used to lock the connection end and the grounding end of the corresponding grounding wire. The grounding locks include a first lock body and a second lock body, which are detachably connected and used to lock the connection end and the grounding end of the grounding wire respectively. The connection end of the overhead line grounding wire is a three-phase grounding hook 131, and the grounding end is a grounding pin 132. Before the connection operation, the grounding wire lock is in a locked state. Because the grounding wire is locked at both ends, the connection operation cannot be performed. The corresponding number of grounding wires and corresponding grounding wire locks after being unlocked by the grounding wire management device can be used as a whole as candidate grounding wires for maintenance personnel to use at will.

[0071] 202. Select at least one set of candidate grounding wires as the target grounding wires to be connected, and unlock the grounding lock corresponding to the target grounding wires to authorize the connection.

[0072] In this process, maintenance personnel bring one or more sets of temporary grounding wires 130 randomly selected to the designated work site. When there is only one target grounding wire connection task, a set of grounding wires randomly selected from the candidate grounding wires is used as the target grounding wire to be connected. When multiple target grounding wire connection tasks are involved, the maintenance personnel select any one of the multiple sets of grounding wires brought to the work site as the target grounding wire 130 to be connected for the current grounding wire connection task. Since the grounding lock 140 is normally in a locked state that locks the connection end and grounding end of the corresponding grounding wire 130, it needs to be unlocked before the connection operation can be performed to release the grounding end and connection end of the grounding wire. Therefore, after selecting the target grounding wire, the maintenance personnel need to connect to the grounding lock corresponding to the target grounding wire one by one through the mobile terminal APP and control its unlocking to release the lock on the connection end and grounding end of the target grounding wire to authorize the connection operation, until multiple target grounding wire connection tasks have been executed.

[0073] 203. After the target grounding wire connection operation is completed, generate the first grounding wire information that is dynamically bound to the target grounding wire connection operation task, and update the maintenance switching operation ticket according to the first grounding wire information.

[0074] The target grounding wire 130 includes a three-phase grounding hook 131 (hanging end), a grounding pin 132 (grounding end), a grounding conductor 133, and an insulating rod 134. The grounding lock includes a detachably connected first lock body and a second lock body. When the grounding lock is locked, the first and second lock bodies are fixedly connected, restricting the movement of the hanging end and the grounding end. The grounding conductor of the grounding wire is bent and its length cannot meet the hanging requirements. When the grounding lock is unlocked, the first and second lock bodies are separated. The insulating rod is used for maintenance personnel to hold. Before performing maintenance on the overhead line, maintenance personnel must first reliably ground the grounding pin of the grounding wire, and then hang the three-phase grounding hooks of the target grounding wire onto each phase of the three-phase transmission line above the line tower to achieve a grounding short circuit of the transmission line, thereby ensuring the safety of maintenance personnel operating on the tower.

[0075] When performing the target grounding wire connection operation, the maintenance personnel first insert the grounding pin 132 into the ground. When the grounding pin is reliably grounded, the grounding pin detection device will automatically trigger the grounding terminal status signal and send it to the server. Subsequently, the maintenance personnel sequentially connect the three-phase grounding hooks 131 of the target grounding wire 130 to the transmission line 160 above the tower. The server, through the grounding hook detection device, detects that the grounding wire connection status has changed to connected, and after determining whether the connection position is correct and that the grounding terminal status signal is grounded, sends a locking command to the mobile terminal. Then, the mobile terminal APP controls the grounding lock 140 to lock again, limiting the part of the grounding pin inserted into the ground so that it cannot be pulled out at will. The system indicates that the current target grounding wire connection operation has been completed. At this time, the mobile terminal APP needs to upload the current operation information to the server. The operation information includes the grounding lock code value corresponding to the target grounding wire, the current status of the grounding lock, and the connection position information. The server determines the grounding wire number and pole number that are dynamically bound to the target grounding wire connection operation task based on the pre-stored correspondence between the grounding wire number and the grounding lock code value, as well as the correspondence between the pole number and the position information. The first grounding information corresponding to the current target grounding wire connection operation task is composed of the above grounding wire number and pole number. The grounding wire number is written into the maintenance switching operation ticket to establish an association with the target grounding wire connection operation task and the pole number.

[0076] 204. Receive the power restoration switching operation ticket sent by the mobile terminal and associated with the updated maintenance switching operation ticket, and generate second ground wire information based on the target ground wire removal operation task contained in the power restoration switching operation ticket, wherein the second ground wire information includes at least a portion of the first ground wire information.

[0077] After the current power outage maintenance task is completed, power needs to be restored to the site. The current shift's maintenance personnel can generate a power restoration switching operation ticket on the mobile terminal APP according to the power restoration requirements. The power restoration switching operation ticket is associated with the maintenance switching operation ticket previously issued by the current shift. The power restoration switching operation task is the reverse operation task of the maintenance switching operation task. The equipment involved in the power restoration switching operation ticket must be the same equipment in the maintenance switching operation ticket. When maintenance personnel select and issue a power restoration operation ticket containing the target grounding wire removal operation task via a mobile terminal APP, based on the association mapping relationship between the power restoration operation ticket and the maintenance operation ticket, and the fact that the target grounding wire connection operation task and the target grounding wire removal operation task are inverse operations, the server searches for the first grounding wire information of the target grounding wire connection operation task corresponding to the target grounding wire removal operation task in the updated maintenance operation ticket and sends it to the mobile terminal 120. The mobile terminal reverse-associates the grounding wire number and tower number in the obtained first grounding wire information with the target grounding wire removal operation task to be operated, and writes it as the second grounding wire information of the target grounding wire removal operation task into the power restoration operation ticket and sends it to the server 110.

[0078] 205. Based on the information of the second ground wire, determine the unlocking information of the target ground wire to be removed.

[0079] The server 110 pre-stores the correspondence between the ground wire number and the ground wire lock code value of the ground wire 130. When the server receives the power restoration and switching operation ticket sent by the mobile terminal 120 and obtains the ground wire number in the second ground wire information corresponding to the target ground wire removal operation task to be operated, the server determines the ground wire lock code value corresponding to the target ground wire removal operation task to be operated according to the pre-stored correspondence between the ground wire number and the ground wire lock code value, and sends the ground wire lock code value as the unlocking information of the target ground wire to be removed to the mobile terminal.

[0080] 206. Read the grounding lock code value corresponding to the target grounding wire to be removed. When the read code value is consistent with the unlocking information, control the grounding lock to unlock and instruct it to be removed.

[0081] Before performing the grounding wire removal operation, in order to achieve targeted removal, the maintenance personnel must first identify the target grounding wire 130 to be removed from among the many grounding wire groups on site and arrive near the location of the target grounding wire. The mobile terminal APP is matched and connected with the grounding lock 140 of the target grounding wire and reads the grounding lock code value. When the read grounding lock code value is consistent with the previously received unlocking information, the mobile terminal APP sends an unlocking command to the corresponding grounding lock to release the grounding lock and instructs the maintenance personnel that after removing the three-phase grounding wire hook, the grounding pin that has been released from the limit can be pulled out from the ground to complete the removal operation of the target grounding wire. Otherwise, an error message is displayed to warn the maintenance personnel that the operation is incorrect.

[0082] For easier understanding, please refer to Figure 3 , Figure 3 This is a schematic diagram of another overhead line grounding wire management system provided in an embodiment of the present invention. The overhead line grounding wire management system 100 includes a server 110, a mobile terminal 120, a grounding wire 130, a three-phase grounding hook 131, a grounding needle 132, a grounding conductor 133, an insulating rod 134, a grounding lock 140, a grounding management device 150, a grounding management host 151, a grounding locking mechanism 152, a transmission line 160, and a line tower. The grounding wire includes a three-phase grounding hook 131, a grounding needle 132, a grounding conductor 133, and an insulating rod 134. The grounding management device 150 includes a grounding management host 151 and multiple grounding locking mechanisms 152. The transmission line 160 is erected above the line tower, and maintenance personnel 170 arrive at the designated location to perform operations.

[0083] Server 110 is the control center of the overhead line grounding wire management system, responsible for the management of various aspects of the overhead line grounding wire management system 100, including personnel permissions, operation tickets, data backup, grounding wire status monitoring and alarms, etc. An APP client is installed on the mobile terminal 120. The client provides a graphical interface and has built-in error prevention logic based on graphical topology calculation. It can generate maintenance switching operation tickets / re-energization switching operation tickets according to task requirements on the mobile terminal APP and perform logic verification. The mobile terminal sends the verified maintenance switching operation tickets / re-energization switching operation tickets to server 110. Grounding lock 140 locks the connection end and grounding end of grounding wire 130 together. Grounding wire 130 and grounding lock 140 can normally be stored as a whole in grounding management device 150. Grounding management device 150 includes grounding management host 151 and multiple grounding locking mechanisms 152, with one grounding locking mechanism corresponding to locking one group of grounding wires. Maintenance personnel 170 are responsible for receiving any grounding wire, arriving at the designated location, unlocking the grounding lock 140, and performing the grounding wire connection operation.

[0084] like Figure 4As shown, the grounding pin 132 includes a grounding pin body, a limit switch, a grounding pin detection device, a grounding pin wireless positioning device, and an audible and visual indicator (not shown in the figure). The audible and visual indicator is used to provide warnings / prompts through sound or light, such as an audible and visual alarm. The grounding pin body 1321 is used to insert into the ground and make contact with the ground. The limit switch 1322 is used to detect whether the grounding pin body of the grounding pin 132 is inserted into the ground to a preset depth by means of its on / off state. The grounding pin detection device is used to determine whether the grounding pin is reliably grounded and trigger the grounding pin status signal to be sent to the server. The grounding wire 133 of the grounding wire is used to connect the grounding pin 132 to the three-phase grounding wire hook 131. The first lock body of the grounding wire lock 140 is connected to the grounding pin, and the second lock body is connected to the hook end of the grounding wire. The grounding wire lock also includes a limiting component (not shown in the figure) that locks and limits the part of the grounding pin inserted into the ground. When the mobile terminal APP controls the grounding wire lock to lock, the limiting component extends laterally relative to the insertion direction of the grounding pin to limit the grounding pin so that it cannot be pulled out at will.

[0085] like Figure 5 As shown, an insulating rod 134 is connected below the three-phase wire hook 131. The three-phase wire hook 131 includes a grounding clamp 1311 and a terminal block 1312. At least one sensing device 1313 is installed inside the top of the grounding clamp 1311. The target main grounding hook 131 also includes a positioning device (not shown) and a hook detection device 1314. The at least one sensing device 1313 includes at least one of a pressure sensor (not shown), a mechanical limit switch (not shown), a magnetic switch (not shown), and an inductive detection switch (not shown). The insulating rod 134 is used for maintenance personnel 170 to hold. The grounding clamp 1311 is used to connect the three-phase grounding hook 131 to the transmission line 160. The terminal block 1312 on the grounding clamp 1311 is used to connect the grounding conductor 133. At least one sensing device 1313 is used to detect the status of the three-phase grounding hook 131.

[0086] Please see Figure 7 , Figure 7 This is a schematic diagram of another dynamic management method for overhead line grounding wires provided in an embodiment of the present invention. The dynamic management method for overhead line grounding wires in this embodiment of the present invention is applied to... Figure 3The overhead line grounding wire management system 100 shown combines server, IoT wireless communication, and sensor technology to achieve dynamic management of the temporary grounding wire hanging and removing process for overhead lines. During hanging, the server 110 controls the grounding wire management device 150 to unlock at least a portion of the grounding wires 130 corresponding to the grounding wire hanging operation task. At least one set of grounding wires is arbitrarily selected as the target grounding wire, and the corresponding grounding wire lock 140 is unlocked. The first grounding wire information is dynamically bound to the target grounding wire hanging operation task, and the maintenance switching operation ticket is updated based on the first grounding wire information. By not pre-binding the grounding wire to the maintenance switching operation ticket and operation task, the grounding wire can be used arbitrarily, and the grounding wire lock can be opened arbitrarily. This reduces the trouble caused by the inability to adjust in time when a fault occurs during operation after pre-setting the grounding wire hanging sequence and position, thus affecting the overall work progress. After hanging is completed, the system can automatically bind the first grounding wire information of the grounding wire to the target grounding wire hanging operation task on-site, automatically associating them without human intervention. This achieves real-time matching and flexible dynamic on-site grounding wire hanging. Management; During dismantling, the grounding wire removal operation task included in the power restoration operation ticket is determined within the scope of the maintenance switching operation ticket, and the corresponding second grounding wire information is determined. The unlocking information of the target grounding wire to be removed is determined through the second grounding wire information. The grounding lock is unlocked and dismantled by reading and comparing the grounding lock code value corresponding to the target grounding wire to be removed. Throughout the process, each operation node does not require frequent authorization, reducing the trouble caused by the inconvenience of remote authorization in the outdoor scenario of overhead lines. It realizes closed-loop management of the entire process of grounding wire use, connection, and removal. It not only associates the connection of temporary grounding wires with the dismantling operation task to prevent accidental or missed dismantling, but also ensures directional dismantling through electrical anti-misoperation interlocking, completely reducing the occurrence of missed grounding wires due to the memory of maintenance personnel. It ensures that the grounding wire removal is truly operated according to the logic memorized by the computer, effectively preventing the occurrence of accidents of closing the circuit with the grounding wire on. Another embodiment of the dynamic control method for overhead line grounding wires in this invention includes:

[0087] 701. Receive maintenance switching operation tickets sent by mobile terminals. When the maintenance switching operation ticket includes a target grounding wire connection operation task, identify at least a portion of the grounding wires in the grounding wire management device as candidate grounding wires and unlock the candidate grounding wires.

[0088] In one feasible implementation, before step 701 above, an APP client is installed on the mobile terminal 120. The client provides a graphical interface and has built-in error prevention logic based on graphical topology calculation. Maintenance personnel can generate maintenance switching operation tickets on the APP according to the maintenance task requirements. There are two ways to generate tickets: one is point-to-diagram ticket generation, that is, after selecting the maintenance task name on the APP, clicking on the graphical device on the primary wiring diagram to simulate the operation, and the system will simultaneously perform topology logic judgment. If it passes, an operation ticket item is generated; if it fails, an error message is displayed. The other is automatic ticket generation, that is, after selecting the maintenance task name on the APP, the system will automatically simulate and generate a maintenance switching operation ticket that matches the task name. The maintenance and switching operation ticket includes operation items and reminders for the relevant power outage equipment. These include the equipment name, the name of the pole to which the equipment belongs, and if it involves temporary grounding wire connection operation, it also includes information such as the number side of the grounding wire, the user side, and the pole to which the connection sign is located. For example, the power outage operation items related to the tie switch include: 1. Disconnect the XX tie switch and drop the XX fuse; 2. Disconnect the XX disconnect switch; 3. Hang the grounding ring on the XX pole; 4. Hang the warning sign on the XX pole.

[0089] The mobile terminal 120 sends the generated maintenance switching operation ticket to the server 110. The server 110 determines whether the obtained maintenance switching operation ticket contains a temporary grounding wire operation task. If it contains a temporary grounding wire operation task, it issues an unlocking control command to the grounding wire management device 150. The ground wire management host 151 of the ground wire management device 150 simultaneously sends unlocking commands to multiple ground wire locking mechanisms 152 according to the received unlocking control command. The multiple ground wire locking mechanisms 152 simultaneously unlock to release the lock on at least a portion of the ground wires stored in the ground wire management device corresponding to the ground wire connection operation task. After the corresponding number of ground wires 130 are unlocked, the ground wire locks 140 set corresponding to the ground wires are also released from the ground wire management device. The unlocked at least a portion of the ground wires can be used arbitrarily by maintenance personnel as candidate ground wires. Before executing the operation task, the ground wire lock locks the connection end and the grounding end of the corresponding ground wire. The ground wire lock includes a first lock body and a second lock body, which are detachably connected and used to lock the connection end and the grounding end of the ground wire respectively. The overhead line grounding wire is connected by a three-phase grounding hook 131 and a grounding pin 132. Before the connection operation, the grounding lock is locked, and the grounding wire cannot be connected because both ends are locked. After being unlocked by the grounding management device, at least a portion of the grounding wire and the corresponding grounding lock can be used as candidate grounding wires by maintenance personnel. At this time, the grounding management device is only used to manage the storage and retrieval of grounding wires and does not preset the grounding wire connection sequence, connection position, or other information. That is, before the temporary grounding wire connection operation begins, the grounding wire is not associated with the maintenance switching operation ticket and operation task, and the grounding lock is not associated with the maintenance operation ticket and operation task. The maintenance personnel of the current shift can freely select one or more sets of grounding wires from the candidate grounding wires to meet the operation requirements (corresponding to one target grounding connection operation task or multiple target grounding wire connection operation tasks). After selecting the required grounding wire, the mobile terminal is used to notify the server to control the grounding management device to relock the remaining grounding wires. The grounding management device records the number of grounding wires stored and retrieved, the status, and other information. By default, all grounding wires in the grounding control device are unlocked for random use, without pre-setting the grounding wire connection sequence or position. This method is more suitable for overhead line operation scenarios and improves the convenience of temporary grounding wire operation.

[0090] 702. Select at least one candidate grounding wire as the target grounding wire to be connected, and unlock the grounding lock corresponding to the target grounding wire to authorize the connection.

[0091] The maintenance switching operation ticket includes the work location information for connecting temporary grounding wires. When maintenance personnel arrive at the designated location at the work site with one or more randomly selected temporary grounding wires, before performing the grounding wire connection operation under the line tower, the grounding lock is in a locked state that locks the connection end and the grounding end of the corresponding grounding wire. The grounding wire cannot be connected because both ends are locked. The grounding lock is a Bluetooth grounding lock. When there is only one target grounding wire connection task, a set of grounding wires randomly selected from the candidate grounding wires is used as the target grounding wire to be connected. The maintenance personnel connect to the Bluetooth grounding lock installed at one end of the target grounding wire via Bluetooth through a mobile terminal APP and control it to unlock, releasing the lock on the connection end and the grounding end of the target grounding wire to authorize the connection operation. When multiple target grounding wire connection tasks are involved, the maintenance personnel select any set of grounding wires brought to the work site as the target grounding wire to be connected for the current grounding wire connection task, and control the Bluetooth grounding lock to unlock. The above selection, unlocking and connection operations are executed one by one until multiple target grounding wire connection tasks are executed. By randomly selecting any grounding wire as the target grounding wire to perform the connection operation, the convenience and flexibility of the grounding wire connection operation are further improved. The grounding wire can be used arbitrarily, and the grounding lock can be opened arbitrarily, reducing the trouble caused by the inability to adjust in time when a fault occurs during operation after the grounding wire connection sequence and position are preset, which affects the overall work progress.

[0092] It should be noted that in one feasible implementation, when unlocking the Bluetooth grounding lock, the maintenance personnel use a mobile terminal via an app to read the Bluetooth grounding lock code value corresponding to the target grounding wire and send an unlocking request to the server. After authorization by the server, an unlocking command is sent to the mobile terminal, which then sends the unlocking command to the corresponding Bluetooth grounding lock for unlocking. Alternatively, the maintenance personnel use a mobile terminal via an app to read the Bluetooth grounding lock code value corresponding to the target grounding wire and generate an unlocking command, which is then directly sent to the Bluetooth grounding lock for unlocking. After successful unlocking, the mobile terminal app reports the Bluetooth grounding lock code value to the server, so that the server knows the grounding lock code value of the grounding wire corresponding to the current grounding wire connection operation task. By reporting the Bluetooth grounding lock code value to the server, the previously randomly selected grounding wire is matched with the target grounding wire connection operation task, achieving dynamic management.

[0093] 703. After the target grounding wire connection operation is completed, generate the first grounding wire information that is dynamically bound to the target grounding wire connection operation task, and update the maintenance switching operation ticket according to the first grounding wire information.

[0094] It should be noted that, as Figure 6As shown, the grounding wire is marked with a grounding wire number, which consists of numbers or letters and numbers. The grounding wire number can be identified manually or via RFID technology. The server pre-stores the correspondence between the grounding wire number and the grounding wire lock code value, as well as the correspondence between the pole number and the location information. Step 703 above, generating the first grounding wire information dynamically bound to the target grounding wire connection operation task, specifically includes: the mobile terminal reporting the lock code value corresponding to the target grounding wire to the server; the server determining the grounding wire number corresponding to the target grounding wire based on the pre-stored correspondence between the grounding wire number and the grounding wire lock code value, and binding the grounding wire number as the first grounding wire information to the target grounding wire connection operation task.

[0095] When performing the target grounding wire connection operation, the maintenance personnel first insert the grounding pin 132 into the ground. When the grounding pin is reliably grounded, the grounding pin detection device will automatically trigger the grounding terminal status signal and send it to the server. Then, the maintenance personnel sequentially connect the three-phase grounding hooks 131 of the target grounding wire 130 to the transmission line 160 above the tower. The server will then detect that the grounding wire status has changed to connected through the grounding hook detection device. After determining whether the connection position is correct and the grounding terminal status signal is confirmed to be connected, the server will send a locking command to the mobile terminal. Then, the mobile terminal APP will control the grounding lock 140 to lock again to limit the part of the grounding pin inserted into the ground so that it cannot be pulled out at will, indicating that the current target grounding wire connection operation is completed. At this time, the mobile terminal APP needs to upload the current operation information to the server. The current operation information includes the grounding lock code value read by the mobile terminal, the grounding lock status, and other information. The server associates and binds the grounding lock code value corresponding to the target grounding wire transmitted back from the mobile terminal and the grounding wire connection location information obtained from the positioning device with the current target grounding wire operation task. Based on the pre-stored correspondence between grounding wire numbers and grounding lock codes, and between pole / tower numbers and location information, it determines the grounding wire number and pole / tower number dynamically bound to the target grounding wire connection operation task. The first grounding information (grounding wire number), composed of the aforementioned grounding wire number and pole / tower number, is then written into the maintenance switching operation ticket, establishing a three-way association between the target grounding wire connection operation task and the pole / tower number. The system automatically updates the grounding wire number to the maintenance switching operation ticket to achieve the binding of the target grounding wire information with the maintenance switching operation ticket, facilitating the orderly management of subsequent operations.

[0096] 704. Obtain the updated maintenance and switching operation ticket from the server; select the corresponding grounding wire connection operation task within the scope of the updated maintenance and switching operation ticket; and generate the target grounding wire removal operation task contained in the power restoration and switching operation ticket in reverse according to the grounding wire connection operation task.

[0097] It should be noted that after the current power outage maintenance task is completed, power needs to be restored to the site. The current shift's maintenance personnel can generate a power restoration switching operation ticket on the mobile terminal APP according to the power restoration requirements. The power restoration switching operation ticket is associated with the maintenance switching operation ticket previously issued by the current shift. The power restoration switching operation task is the reverse operation task of the maintenance switching operation task. The equipment involved in the power restoration switching operation ticket must be the same equipment in the maintenance switching operation ticket.

[0098] When maintenance personnel issue a power restoration switching operation ticket containing a target grounding wire connection operation task on a mobile terminal APP, they first search the server for the target maintenance switching operation ticket associated with the power restoration switching operation task. The mobile terminal APP can automatically issue a target grounding wire removal operation task that removes at least a portion of the grounding wires within the scope of the target maintenance switching operation ticket. Alternatively, it can select a portion of the target grounding wires corresponding to the target grounding wire connection operation task within the scope of the target maintenance switching operation ticket to issue a target grounding wire removal operation task that removes a portion of the grounding wires. By associating power restoration switching operation tickets with maintenance switching operation tickets, targeted removal can only be performed on grounding wires already connected within the scope of the current maintenance switching operation ticket, further optimizing the orderly management of temporary grounding wires on overhead lines.

[0099] 705. Receive the power restoration switching operation ticket sent by the mobile terminal and associated with the updated maintenance switching operation ticket, and generate second ground wire information based on the target ground wire removal operation task contained in the power restoration switching operation ticket, wherein the second ground wire information includes at least a portion of the first ground wire information.

[0100] It should be noted that the content of the power restoration and switching operation ticket is mapped to the maintenance and switching operation ticket, including operation items and prompts for the relevant power supply equipment. This includes information such as the equipment name, the name of the tower to which the equipment belongs, the size of the grounding wire (large or small side), the user side, and the tower where the connection sign is located. For example, the power supply operation items related to the tie switch include: 1. Remove the warning sign on the XX tower; 2. Remove the grounding ring of the XX tower; 3. Close the XX disconnect switch; 4. Close the XX switch and the drop-out fuse.

[0101] In one feasible implementation, maintenance personnel select and issue a power restoration and switching operation ticket containing the target grounding wire removal task via a mobile terminal APP. Simultaneously, based on the association mapping between the power restoration and switching operation tickets and the maintenance switching operation tickets, and considering that the target grounding wire connection and removal tasks are inverse operations, the server searches for the first grounding wire information corresponding to the target grounding wire removal task in the updated maintenance switching operation ticket and sends it to the mobile terminal. The mobile terminal then reverse-associates the grounding wire number and tower number from the obtained first grounding wire information with the target grounding wire removal task to be performed, writing this as the second grounding wire information for the target grounding wire removal task into the power restoration and switching operation ticket and sending it to the server. This reverse association confirms the grounding wire number of the target grounding wire to be removed and writes it into the power restoration and switching operation ticket. This process facilitates maintenance personnel's more intuitive identification of the grounding wire to be removed in the field environment and also facilitates system management of various operation information, making the entire operation process more orderly.

[0102] 706. Based on the information of the second ground wire, determine the unlocking information of the target ground wire to be removed.

[0103] It should be noted that the server pre-stores the correspondence between ground wire numbers and ground wire lock codes. When the server receives a power restoration and switching operation ticket from the mobile terminal and retrieves the ground wire number from the second ground wire information corresponding to the target ground wire removal operation task, the server determines the ground wire lock code value corresponding to the target ground wire removal operation task based on the pre-stored correspondence between the ground wire number and the ground wire lock code value. This ground wire lock code value is then sent to the mobile terminal as the unlocking information for the target ground wire to be removed. By generating and sending the unlocking information for the target ground wire to be removed to the mobile terminal of the on-site maintenance personnel for targeted removal, the accidental removal of ground wires is effectively prevented, ensuring orderly management.

[0104] 707. Read the grounding lock code value corresponding to the target grounding wire to be removed. When the read code value is consistent with the unlocking information, control the grounding lock to unlock and instruct it to be removed.

[0105] It should be noted that before performing the grounding wire removal operation, in order to achieve targeted removal, maintenance personnel must first identify the target grounding wire to be removed from among the many grounding wire groups on site and arrive near the location of the target grounding wire. The mobile terminal APP is paired and connected with the Bluetooth grounding lock of the target grounding wire, and reads the Bluetooth grounding lock code value. When the read Bluetooth grounding lock code value matches the previously received unlocking information, the mobile terminal APP sends an unlocking command to the corresponding Bluetooth grounding lock to release the Bluetooth grounding lock from the grounding pin. This allows maintenance personnel to remove the grounding pin, which has been released from the limit, from the ground after removing the three-phase grounding wire hook, thus completing the removal of the target grounding wire. Otherwise, an error message is displayed to warn maintenance personnel of an operational error. The targeted and orderly removal of temporary grounding wires is achieved through an electrical anti-misoperation interlocking method.

[0106] In one feasible implementation, multiple line towers exist within the on-site work area. Before performing the grounding wire removal operation, it is necessary to identify and locate the corresponding on-site line tower in the power restoration and switching operation ticket. Identification can be done manually, where maintenance personnel locate the tower with the tower number from the second grounding information. Alternatively, RFID identification can be used, where RFID tags are attached to the on-site line towers, and maintenance personnel use a handheld mobile terminal to verify the RFID tag and determine if it matches the tower number. After confirming that the current on-site tower is the target line tower, the maintenance personnel need to further verify if the grounding wire number currently connected to the target line tower matches the grounding wire number in the second information. If they match, the grounding wire of the current on-site tower can be confirmed as the target grounding wire to be removed. Similarly, the grounding wire is marked with a grounding wire number, which consists of numbers or letters and numbers. The grounding wire number can be identified manually or using RFID technology. By identifying and confirming multiple related pieces of information, targeted and orderly demolition was further ensured, effectively preventing accidental demolition.

[0107] In this embodiment of the invention, a special type of grounding lock is used to lock the grounding end and the connection end of the corresponding grounding wire and store them in the grounding wire management device. The grounding wire can be flexibly used before connection, without pre-setting the connection sequence or position. The grounding wire can be used arbitrarily, and the grounding lock can be opened arbitrarily. This reduces the trouble caused by the inability to adjust in time when a fault occurs during operation after pre-setting the grounding wire connection sequence and position, thus affecting the overall work progress. After connection, the system automatically dynamically binds the first grounding wire information with the target grounding wire connection operation task and updates the maintenance switching operation ticket, realizing real-time matching and flexible dynamic management of grounding wire connection on-site. By associating the power restoration switching operation ticket with the switching operation ticket, the system determines the target grounding wire removal operation task containing the second grounding wire information, ensuring that the grounding wire removal in the power restoration switching operation ticket is performed correctly. In addition to the task corresponding to the grounding wire connection task in the maintenance switching operation ticket, the target grounding wire can only be removed within the scope of the corresponding maintenance switching operation ticket. This ensures the orderly management of grounding wire connection and removal during multi-shift operations, effectively preventing accidental removal or removal from buildings. By determining the unlocking information of the target grounding wire to be removed in the server background, and by reading and comparing the grounding lock code value corresponding to the target grounding wire to be removed, the grounding lock is unlocked. The electrical anti-misoperation interlocking method ensures directional removal, completely reducing the occurrence of missing grounding wires due to the memory of maintenance personnel. This ensures that the grounding wire removal is truly operated according to the logic memorized by the computer, effectively preventing the occurrence of accidents caused by closing the circuit with the grounding wire connected. Moreover, the operation nodes do not need frequent authorization during the entire process, reducing the trouble caused by the inconvenience of remote authorization in outdoor scenarios with overhead lines. Throughout the process of attaching and removing multiple sets of temporary grounding wires for overhead lines, flexible on-site matching and dynamic management were achieved. Technical means were used to effectively ensure the correctness of the attachment and removal of temporary grounding wires. The entire process of taking, attaching, removing and returning the temporary grounding wires was recorded through a mobile terminal APP, forming a closed-loop management system, which improved the efficiency of related operations and ensured the safety of personnel.
