Abstract
Description
Technical Field
[0001] This application relates to the field of power grid construction safety technology, and in particular to a state analysis method and system for power grid grounding wires. Background Technology
[0002] In power grid construction, the grounding wire is a core protective device to ensure the personal safety of workers. Its function is to discharge the residual charge and induced charge of the de-energized equipment to the ground, preventing electric shock accidents caused by sudden power restoration or induced voltage.
[0003] The specific process includes: Power outage and voltage testing: Strictly implement the five prevention measures of power outage, voltage testing, grounding, tagging, and installing barriers. First, de-energize the equipment or line to be worked on, then use a voltage tester that matches the voltage level to test for voltage. Work can only proceed after confirming that there is no voltage. Check the grounding wire: Verify that the voltage level of the grounding wire matches the equipment to be worked on; check that the conductor has no broken strands, the wire clamp is free of rust, and the spring tension is normal; ensure that the connection between the grounding end and the equipment end is intact; determine the grounding point: The grounding end should be connected to a dedicated grounding electrode or grounding network, and it is strictly forbidden to connect it to non-dedicated grounding bodies such as metal railings or cable sheaths.
[0004] As can be seen from the above introduction, the installation and removal of grounding wires currently rely mainly on manual confirmation by the grounding wire installer, telephone reporting to the dispatcher, and the dispatcher issuing dispatch orders based on the on-site report. If any link in this process results in a false report or omission, an accident due to misoperation will occur. Summary of the Invention

[0025] The technical solutions in this application will be further described in detail below with reference to the accompanying drawings.
[0026] This application discloses a state analysis method for power grid grounding wires. In some examples, the state analysis method for power grid grounding wires disclosed in this application includes the following steps: S101, in response to the received repair order instruction, query the task order associated with the repair order instruction and associate the queried task order with the repair order; S102, establishes a data communication relationship between the terminal that issues the maintenance order instruction and the grounding terminal; S103, determine the position coordinates of the grounding wire terminal based on the start command sent by the grounding wire terminal; S104, Verify the position coordinates of the grounding wire end, and the position coordinates of the grounding wire end are associated with and bound to the task order; S105, obtain the grounding status of the grounding wire end and query the position coordinates and grounding status of the grounding wire end at intervals during the execution of the task.
[0027] Overall, the technical solution provided in this application involves installing a smart terminal, namely the grounding wire end, on the grounding wire. The grounding wire end communicates with the cloud for data. When performing operations, workers carry the assigned work terminal (smart operating device, such as a mobile phone).
[0028] During the operation, the operation terminal first scans the smart terminals on the ground wire, and then sends the scanned information to the cloud. Therefore, the execution entity of this application is the cloud. Please refer to [link / reference]. Figure 1 In step S101, in response to the received maintenance order instruction (issued by the work terminal), the cloud queries the task order associated with the maintenance order instruction and associates the queried task order with the maintenance order.
[0029] At this point, the smart terminal operates by first selecting a repair order, and then scanning the smart terminal on the ground wire. The repair order is then bound to the smart terminal on the ground wire.
[0030] Next, in step S102, the cloud establishes a data communication relationship with the grounding terminal through the terminal that issued the maintenance order instruction. At this time, the terminal that issued the maintenance order instruction (operation terminal) is used as a relay, specifically, it creates a wireless network at the construction site. Figure 1 As shown.
[0031] Alternatively, the grounding wire at this point may have communication capabilities, allowing it to communicate directly with the cloud, such as... Figure 2 As shown.
[0032] In step S103, the position coordinates of the grounding wire are determined according to the start command sent by the grounding wire. The start command of the grounding wire indicates that the grounding wire has started working. The position coordinates of the grounding wire are obtained by the position module built into the grounding wire and then sent to the cloud.
[0033] In step S104, the position coordinates of the grounding wire end are verified. The position coordinates of the grounding wire end are associated with and bound to the task sheet. The specific method is to query in the task sheet, which records the position coordinates of the operation. At this time, the position coordinates of the grounding wire end need to be within the area corresponding to the position coordinates of the operation recorded in the task sheet.
[0034] Finally, in step S105, the grounding status of the grounding wire is obtained, and the position coordinates and grounding status of the grounding wire are queried at intervals during the execution of the task. The grounding status of the grounding wire is given by the grounding wire itself. Queries querying the position coordinates and grounding status of the grounding wire during the execution of the task refers to querying the grounding status and position coordinates of the grounding wire at intervals or according to a set frequency on the cloud.
[0035] In some cases, verifying the location coordinates of the grounding terminal also includes determining the location coordinates and grounding status of the auxiliary grounding terminals associated with it. An auxiliary grounding terminal refers to a grounding terminal installed on other grounding terminals that participate in a task. Auxiliary grounding terminals are characterized by lacking network communication and positioning capabilities, with the aim of simplifying the hardware structure.
[0036] In some cases, there are two ways to confirm the location coordinates: sending a feedback coordinate command to the ground wire and sending a coordinate command back to the ground wire at a set frequency.
[0037] In some cases, the grounding status of the grounding terminal is confirmed by sending a feedback coordinate command to the grounding terminal and / or the grounding terminal sends a back coordinate command at a set frequency; When confirming the grounding status at the grounding terminal, potential detection and spark detection are used for confirmation.
[0038] In some cases, the location coordinates and grounding status of the auxiliary grounding terminal associated with the grounding terminal are determined in the following ways: Establish a data communication relationship between the grounding wire end and the auxiliary grounding wire end; During the execution of the task order, the position coordinates and grounding status of the auxiliary grounding wire terminal associated with the grounding wire terminal are queried at intervals, such as... Figure 3 As shown.
[0039] In this method, the grounding wire end and the auxiliary grounding wire end communicate with each other through short-range communication methods such as NFC and Bluetooth. The position coordinates of the auxiliary grounding wire end are obtained using, for example, a phase difference ranging algorithm. The grounding status of the auxiliary grounding wire end is directly transmitted through the short-range communication network.
[0040] In some possible implementations, the position coordinates and grounding status of the auxiliary grounding terminal associated with the grounding terminal are fed back to the grounding terminal.
[0041] In some possible implementations, when the position coordinates and grounding status of the auxiliary grounding wire associated with the grounding wire cannot be fed back to the grounding wire, the grounding wire sends an early warning signal and simultaneously sends an early warning signal back to the cloud, such as... Figure 4 and Figure 5 As shown.
[0042] This application also provides a condition analysis device for power grid grounding wires, comprising: The information query unit is used to respond to the received repair order instruction, query the task order associated with the repair order instruction, and associate the queried task order with the repair order; The communication unit is used to establish a data communication relationship between the terminal that issues the maintenance order instruction and the grounding terminal; The position determination unit is used to determine the position coordinates of the grounding wire terminal based on the start command sent by the grounding wire terminal. A location verification unit is used to verify the location coordinates of the grounding wire end, and the location coordinates of the grounding wire end are associated and bound to the task order. The verification unit is used to obtain the grounding status of the grounding wire end and periodically query the position coordinates and grounding status of the grounding wire end during the execution of the task order.
[0043] Furthermore, verifying the location coordinates of the grounding wire end also includes determining the location coordinates and grounding status of the auxiliary grounding wire end associated with the grounding wire end.
[0044] Furthermore, confirming the location coordinates includes sending a feedback coordinate command to the ground wire end and / or the ground wire end sending a back coordinate command at a set frequency.
[0045] Furthermore, confirm the grounding status of the grounding wire terminal and send a feedback coordinate command to the grounding wire terminal and / or the grounding wire terminal sends a counter-coordinate command at a set frequency; When confirming the grounding status at the grounding terminal, potential detection and spark detection are used for confirmation.
[0046] Furthermore, determining the location coordinates and grounding status of the auxiliary grounding wire terminal associated with the grounding wire terminal includes: Establish a data communication relationship between the grounding wire end and the auxiliary grounding wire end; During the execution of the task, the position coordinates and grounding status of the auxiliary grounding terminal associated with the grounding terminal are queried at intervals.
[0047] Furthermore, the position coordinates and grounding status of the auxiliary grounding wire end associated with the grounding wire end are fed back to the grounding wire end.
[0048] Furthermore, if the position coordinates and grounding status of the auxiliary grounding wire end associated with the grounding wire end cannot be fed back to the grounding wire end, the grounding wire end issues an early warning signal and simultaneously feeds back the early warning signal to the cloud.
