[0060] DESCRIPTION OF THE REFERENCE NUMERALS

[0061] 01. Controller 02. Operation and maintenance bracelet Detailed implementation manners

[0062] The following will describe in detail the specific implementation manners of the embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only for explaining and illustrating the embodiments of the present invention, and are not used to limit the embodiments of the present invention.

[0063] Figure 1 is a flowchart of a supervision method for the operation and maintenance of a digital converter station according to an embodiment of the present invention. In Figure 1 it, the supervision method may include:

[0064] In step S10, obtain the area for the operation and maintenance of the digital converter station. Among them, before planning the operation and maintenance route, it is necessary to clarify the area where the digital converter station needs to perform operation and maintenance, and select this area in the system for operation and maintenance route planning.

[0065] In step S11, obtain the number of operation and maintenance personnel. Among them, the number of operation and maintenance personnel needs to be manually counted, and the number of operation and maintenance personnel is transmitted to the system for operation and maintenance route planning.

[0066] In step S12, obtain the number of operation and maintenance bracelets according to the number of operation and maintenance personnel. Among them, after clarifying the number of operation and maintenance personnel, the system for operation and maintenance route planning determines the number of operation and maintenance bracelets required according to the number of operation and maintenance personnel, so as to facilitate the subsequent planning of the operation and maintenance route.

[0067] In step S13, obtain the operation and maintenance route of each operation and maintenance bracelet according to the area for the operation and maintenance of the digital converter station and the number of operation and maintenance bracelets. Among them, after clarifying the area that needs to be operated and maintained and the number of operation and maintenance bracelets, the system for operation and maintenance route planning divides the operation and maintenance route of each operation and maintenance bracelet according to the area and the number of operation and maintenance bracelets.

[0068] In step S14, match and transmit the operation and maintenance route to the corresponding operation and maintenance bracelet. In order to facilitate the operation and maintenance personnel to clarify the area and route they need to operate and maintain and avoid duplicate operation and maintenance, the divided operation and maintenance routes need to be transmitted to each operation and maintenance bracelet respectively.

[0069] In step S15, match the operation and maintenance bracelet and the operation and maintenance personnel. Among them, after the operation and maintenance route is received on the operation and maintenance bracelet, each operation and maintenance bracelet needs to be matched to the corresponding operation and maintenance personnel, and the operation and maintenance personnel put on the corresponding operation and maintenance bracelet.

[0070] In step S16, each operation and maintenance personnel executes the operation and maintenance route of the corresponding operation and maintenance bracelet. Among them, each operation and maintenance personnel performs operation and maintenance according to the operation and maintenance route on the operation and maintenance bracelet they wear, avoiding the situation of duplicate operation and maintenance and missed inspection by the operation and maintenance personnel, realizing the unified management of operation and maintenance tasks, and improving the operation and maintenance efficiency of the operation and maintenance personnel.

[0071] In steps S10 to S16, first, clarify the area to be inspected and the number of inspection personnel performing the inspection tasks, and determine the number of inspection bracelets based on the number of inspection personnel. Then, the system for planning the inspection route reasonably plans the inspection route corresponding to each inspection bracelet according to the area and the number of inspection bracelets, and matches the inspection bracelets with the inspection personnel. The inspection personnel perform the inspection tasks according to the corresponding inspection routes, which can realize the unified management and planning of the inspection tasks, and thus improve the inspection efficiency of the inspection personnel.

[0072] For the inspection work tasks of traditional converter stations, it is difficult to make overall and reasonable arrangements, and situations of repeated inspections or missed inspections often occur. In this embodiment of the present invention, by using the system for planning the inspection route to transmit the divided inspection routes to each inspection bracelet, the unified planning and management of the inspection tasks are realized, which can improve the inspection efficiency of the inspection personnel and avoid the situations of repeated inspections and missed inspections.

[0073] In this embodiment of the present invention, the relationship between the number of inspection bracelets and the number of inspection personnel can be various forms known to those skilled in the art, such as 1:1, 2:1, etc. However, in a preferred example of the present invention, considering the convenience of inspection personnel using the inspection bracelets for inspection, the number of inspection bracelets is 1:1 with the number of inspection personnel, that is, each inspection personnel corresponds to one inspection bracelet, which is convenient for the inspection personnel to carry and use during the inspection.

[0074] In this embodiment of the present invention, in order to determine the inspection route of each inspection bracelet, it is also necessary to process the inspection area and the number of inspection bracelets. Specifically, the supervision method may further include the steps as Figure 2 shown. In Figure 2 , the supervision method may further include:

[0075] In step S20, obtain the route length of the area for digital converter station inspection. Among them, after clarifying the area for digital converter station inspection, it is also necessary to determine the overall route to be inspected and its length according to the area.

[0076] In step S21, calculate the length of the inspection route of each inspection bracelet according to formula (1),

[0077]

[0078] where l is the length of the inspection route of each inspection bracelet, L is the route length of the area for digital converter station inspection, and m is the number of inspection bracelets.

[0079] In step S22, the route of the operation and maintenance area of the digital converter station is equally divided according to the length of the operation and maintenance route of each operation and maintenance bracelet, and the operation and maintenance route of each operation and maintenance bracelet is formed. Among them, after calculating the length of the operation and maintenance route of each operation and maintenance bracelet, the size of the area to be inspected by each operation and maintenance personnel is determined. At this time, it is also necessary to equally divide the total operation and maintenance route of the operation and maintenance area of the digital converter station according to the length of the operation and maintenance route of each operation and maintenance bracelet, and then form the operation and maintenance route corresponding to each operation and maintenance bracelet, which is convenient for the operation and maintenance personnel to perform the operation and maintenance tasks according to the operation and maintenance route.

[0080] In steps S20 to S22, it is necessary to determine the total operation and maintenance route and its length according to the operation and maintenance area of the digital converter station, and calculate the length of the operation and maintenance route of each operation and maintenance bracelet according to the number of operation and maintenance bracelets. The operation and maintenance route planning system equally divides the total operation and maintenance route according to the length of the operation and maintenance route of each operation and maintenance bracelet, and then obtains the operation and maintenance route corresponding to each operation and maintenance bracelet.

[0081] In this embodiment of the present invention, in order to ensure the overall operation and maintenance efficiency of the operation and maintenance personnel after encountering a failure during operation and maintenance, it is also necessary to re-divide the subsequent operation and maintenance route of the operation and maintenance personnel. Specifically, the supervision method may further include, for example Figure 3 the steps shown. In Figure 3 , the supervision method may further include:

[0082] In step S30, a failure signal of each operation and maintenance bracelet is obtained. Among them, when the operation and maintenance personnel encounter a failure of the converter station system during the operation and maintenance process, they need to press the failure button on the operation and maintenance bracelet. At this time, the operation and maintenance bracelet sends the positioning of the failure point to the operation and maintenance route planning system.

[0083] In step S31, it is judged whether a failure signal is obtained. Among them, in order to promptly process the failure point discovered by the operation and maintenance personnel during the operation and maintenance process to reduce the loss of the digital converter station, the operation and maintenance route planning system needs to monitor the failure signal in real time.

[0084] In step S32, in the case of judging that a failure signal is obtained, a failure location warning is issued. Among them, if the operation and maintenance route planning system receives a failure signal, it means that the operation and maintenance personnel have discovered the failure location of the digital converter station. In order to determine whether the system connected to the failure also has a failure, when the operation and maintenance route planning system obtains a failure signal, it is also necessary to transmit the failure location to other operation and maintenance bracelets for sharing, and other operation and maintenance personnel conduct troubleshooting by analogy to ensure the stable operation of the digital converter station.

[0085] In step S33, obtain the secondary division signal of the operation and inspection bracelet. Among them, when the operation and inspection personnel discover a fault in the digital converter station system, it is also necessary to judge the severity of the fault point. If the operation and inspection personnel judge that it is necessary to further determine the problem of the fault point or it takes time to handle the fault, the secondary division button on the operation and inspection bracelet needs to be pressed.

[0086] In step S34, judge whether the secondary division signal is obtained. Among them, in order to improve the efficiency of operation and inspection, the operation and inspection route planning system also needs to monitor the secondary division signal in real time.

[0087] In step S35, in the case of judging that the secondary division signal is obtained, perform the secondary division operation. Among them, if the operation and inspection route planning system receives the secondary division signal, it means that the operation and inspection personnel who discovered the fault point cannot carry out the subsequent operation and inspection on time, and the subsequent operation and inspection tasks of this operation and inspection personnel need to be assigned to other operation and inspection personnel for execution.

[0088] In step S36, in the case of judging that the secondary division signal is not obtained, execute according to the original operation and inspection route. Among them, if the operation and inspection route planning system does not receive the secondary division signal, it means that the operation and inspection personnel at the fault point can handle the problem of the fault point in time and can continue to execute the remaining part of the operation and inspection route. Therefore, it is not necessary to divide the remaining operation and inspection route of this operation and inspection personnel.

[0089] In step S37, in the case of judging that the fault signal is not obtained, execute according to the original operation and inspection route. Among them, if the operation and inspection route planning system does not receive the fault signal, it means that the operation and inspection personnel have not discovered the fault of the digital converter station for the time being. Therefore, each operation and inspection personnel can perform the operation and inspection according to the originally planned operation and inspection route.

[0090] In steps S30 to S37, the operation and inspection route planning system needs to first monitor the fault signal of the operation and inspection bracelet to judge whether there is a fault in the digital converter station. In the case of determining that there is a fault in the digital converter station, monitor the secondary division signal to judge whether the operation and inspection personnel need the help of other operation and inspection personnel to perform the remaining operation and inspection tasks. By obtaining the secondary signal, the operation and inspection route planning system can further improve the operation and inspection efficiency of the digital converter station and ensure the timely solution of the fault problem.

[0091] In this embodiment of the present invention, in order to ensure the efficient completion of the operation and inspection tasks, when the operation and inspection personnel discover and handle the fault point, other operation and inspection personnel also need to perform the operation and inspection on the remaining operation and inspection route of this operation and inspection personnel. Specifically, the supervision method may further include, for example Figure 4 as shown in the steps. In Figure 4 , the supervision method may further include:

[0092] In step S40, obtain the remaining route length of the inspection route corresponding to the inspection bracelet that emits a fault signal. Among them, the system for planning the inspection route obtains the remaining inspection route and its length based on the position of the fault point and the route that the inspection personnel who discovered the fault point have inspected.

[0093] In step S41, obtain the number of secondary division signals. Among them, in order to clarify how many inspection personnel cannot perform normal inspections, it is also necessary to determine the number of secondary division signals received by the system for planning the inspection route. The number of secondary division signals represents the number of inspection personnel who cannot perform normal inspections.

[0094] In step S42, calculate the newly added inspection route length for each remaining inspection bracelet according to formula (2).

[0095]

[0096] where l 1 is the newly added inspection route length for each remaining inspection bracelet, L 1 is the remaining route length of the inspection route corresponding to the inspection bracelet that emits a fault signal, and n is the number of secondary division signals.

[0097] In step S43, equally divide the remaining route of the inspection route corresponding to the inspection bracelet that emits a fault signal according to the newly added inspection route length for each remaining inspection bracelet and form the newly added inspection route for each inspection bracelet. Among them, after determining the length of the newly added inspection route for the remaining inspection bracelets, equally divide the previously summarized remaining inspection route and its length, and send the newly added inspection routes after division to the remaining inspection bracelets respectively to ensure the overall inspection efficiency of the digital converter station.

[0098] In steps S40 to S43, summarize the remaining inspection routes that cannot be normally executed, calculate the newly added inspection route length for each remaining inspection bracelet according to the number of secondary division signals, and finally plan the newly added routes for each remaining inspection bracelet according to the length of the newly added inspection route. The remaining inspection personnel assist in the inspection to ensure the efficient completion of the inspection tasks of the digital converter station.

[0099] In this embodiment of the present invention, in order to determine whether the system associated with the discovered fault point also has a fault, it is also necessary to perform a detailed inspection on the system associated with the discovered fault point. Specifically, the supervision method may further include the steps as Figure 5 shown. In Figure 5 , the supervision method may further include:

[0100] In step S50, the fault location is obtained. Among them, when the operation and maintenance personnel discover a fault, they need to press the fault button on the operation and maintenance bracelet in a timely manner, and then send the fault location to the system for operation and maintenance route planning.

[0101] In step S51, the location associated with the fault location is obtained. Among them, when the system for operation and maintenance route planning obtains the fault signal, it timely determines and marks the location associated with the fault location.

[0102] In step S52, the associated location and the operation and maintenance route are matched. Among them, in order to facilitate other operation and maintenance personnel to clarify whether there is a location associated with the fault location system in their own operation and maintenance route, the system for operation and maintenance route planning matches the location associated with the fault location to the previously planned operation and maintenance route.

[0103] In step S53, the matching result is sent to other operation and maintenance bracelets. Among them, in order to clarify whether there is also a fault in the system associated with the currently discovered fault point, the associated location needs to be sent to the corresponding operation and maintenance bracelet.

[0104] In steps S50 to S53, the system for operation and maintenance route planning finds out the locations of the systems related to the location of the discovered fault point, matches them with the previously planned operation and maintenance route, and transmits them to the corresponding operation and maintenance bracelets, thereby facilitating other operation and maintenance personnel to troubleshoot the associated system faults and improving the efficiency of operation and maintenance.

[0105] In this embodiment of the present invention, in order to ensure the accuracy of obtaining the secondary division signal, the operation and maintenance personnel also need to actively control the sending of the secondary division signal. Specifically, the supervision method may further include as Figure 6 shown in the steps. In Figure 6 , the supervision method may further include:

[0106] In step 60, a secondary division confirmation signal is sent to the operation and maintenance bracelet that sent the fault signal. Among them, in order to determine whether the time for the operation and maintenance personnel to handle the fault problem affects the subsequent normal operation and maintenance, it is necessary to provide the time for the operation and maintenance personnel to judge the severity of the fault problem. Therefore, when the system for operation and maintenance route planning obtains the fault signal, a secondary division confirmation signal is sent to the operation and maintenance bracelet of the operation and maintenance personnel to confirm whether a secondary division operation is required.

[0107] In step S61, the secondary division signal of the operation and maintenance bracelet is obtained. Among them, the system for operation and maintenance route planning monitors the feedback confirmation signal on the operation and maintenance bracelet in real time, that is, the secondary division signal.

[0108] In steps S60 to S61, in order to determine whether the time taken by the operation and maintenance personnel to handle the fault problem affects the subsequent normal operation and maintenance, it is necessary to provide the time when the operation and maintenance personnel judge the severity of the fault problem. At the same time, in order to prevent the operation and maintenance personnel from forgetting to press the secondary division button, a secondary division confirmation signal needs to be sent to the operation and maintenance bracelet where the fault occurs, so as to process and allocate the remaining operation and maintenance routes of the operation and maintenance personnel in a timely manner.

[0109] In this embodiment of the present invention, in order to prevent the operation and maintenance personnel from forgetting to confirm the secondary division confirmation signal, the secondary division confirmation signal needs to be repeatedly sent. Specifically, the supervision method may further include as Figure 7 shown in the steps. In Figure 7 , the supervision method may further include:

[0110] In step S70, in the case where it is determined that the secondary division signal is not obtained, the original operation and maintenance route is executed. Among them, if the operation and maintenance route planning system does not receive the secondary division signal, it means that the operation and maintenance personnel have not confirmed the secondary division confirmation signal and have not pressed the secondary division button.

[0111] In step S71, the secondary division confirmation signal is sent to the operation and maintenance bracelet that sent the fault signal again within a preset time interval, and it is returned to judge whether the secondary division signal is obtained. Among them, in order to prevent the operation and maintenance personnel from forgetting to confirm the secondary division confirmation signal, the secondary division confirmation signal is sent again within a predetermined time interval for the purpose of reminder.

[0112] In steps S70 to S71, if the operation and maintenance route planning system does not receive the secondary division signal, it means that the operation and maintenance personnel have not confirmed the secondary division confirmation signal. At this time, it is impossible to judge whether the operation and maintenance personnel do not need to perform the secondary division operation on the remaining operation and maintenance routes or have forgotten to confirm, so it is necessary to repeat the sending to remind the operation and maintenance personnel.

[0113] In this embodiment of the present invention, considering the average processing time of the fault points in the digital converter station, the preset time interval is 10 - 20 minutes.

[0114] On the other hand, the present invention also provides a supervision system for the operation and maintenance of a digital converter station. Specifically, the supervision system may include a plurality of operation and maintenance bracelets 02 and a controller 01. Specifically, the controller 01 is used to execute the supervision method as described in any of the above.

[0115] Through the above technical solution, the supervision method and system for the operation and maintenance of the digital converter station provided by the present invention obtain the operation and maintenance routes of each operation and maintenance bracelet 02 through the operation and maintenance areas of the digital converter station and the number of operation and maintenance bracelets 02. Finally, each operation and maintenance route is matched to the corresponding operation and maintenance bracelet 02, and the operation and maintenance personnel execute the corresponding operation and maintenance tasks according to the operation and maintenance routes on the corresponding operation and maintenance bracelet 02, thereby realizing the unified management of the operation and maintenance tasks and improving the inspection efficiency.

[0116] It should also be noted that the term "including", "comprising" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, commodity or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, commodity or device. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of additional identical elements in the process, method, commodity or device including the element.

[0117] The above are only embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications.
