Description

Technical Field

[0001] The present invention relates to the technical field of power grounding wire safety management and control, and specifically to a power grounding wire safety management and control method and system based on the Internet of Things. Background Art

[0002] With the rapid development of modern society, the demand for electricity is increasing, and the safety and efficiency of power grid operations have become important considerations for the development of the power industry. In the power system, grounding wires are an important tool to ensure the safety of workers, and their installation and removal are key maintenance operations. However, the traditional power grid operation grounding control system has problems such as unreal-time information and inaccurate control, which makes it difficult to meet the requirements of current power grid operation. In order to improve the controllability, controllability and controllability of power grounding wire management, the introduction of Internet of Things technology has brought new solutions to the power industry.

[0003] Internet of Things technology refers to a network that connects any object to the Internet through information sensing devices and in accordance with agreed protocols to exchange information and communicate, so as to achieve intelligent identification, positioning, tracking, monitoring and management. In the power industry, Internet of Things technology can organically connect various links such as power equipment, operators, and management systems to achieve real-time data collection, transmission and processing, thereby improving the safety and efficiency of power grid operations.

[0004] In the Chinese invention application with application publication number CN113109736A, a portable short-circuit grounding wire monitoring system and monitoring method based on blockchain are disclosed, including a grounding wire data acquisition system, a blockchain system and a management system, both of which are communicatively connected to the blockchain system; the grounding wire data acquisition system is used to collect usage status data of the portable short-circuit grounding wire; the blockchain system is used to encrypt and consensus-confirm the usage status data acquisition encryption algorithm and consensus algorithm to form blocks, and add the formed blocks to the blockchain; the management system is used to monitor and display the usage status data stored in the blockchain system.

[0005] In the above invention application, the usage status of the grounding wire is determined by analyzing the geographical location data of the grounding wire, the pressure data between the grounding wire fastener, the distance from the protective plate to the ground, the current angle data of the grounding wire drill rod and the depth data of the ground drill into the ground. However, it can only be judged whether the grounding wire is hung. If the grounding wire is damaged or has poor contact, for example, the grounding wire itself has quality problems such as breakage, aging, etc. that cannot be identified, when the equipment has leakage or other electrical failures, poor grounding will not be able to transmit the current to the earth in time, thereby increasing the risk of electric shock.

[0006] To this end, the present invention provides a power grounding wire safety management and control method and system based on the Internet of Things. Summary of the invention

The present invention obtains the operating status of each power equipment and adopts different analysis strategies for power grounding wires in different operating states. It can determine whether the grounding wire is correctly connected before the equipment is operated, and analyze the tension on both sides of the equipment power grounding wire when the equipment is running. It can promptly detect whether the grounding wire is loose, vibrates violently, or has other forms of connection abnormalities, thereby preventing safety accidents caused by poor contact of the grounding wire. At the same time, the connection abnormality frequency Pf and functional abnormality frequency Gf of each power grounding wire are analyzed, and corresponding early warning processing strategies are adopted. The risks of the power grounding wire can be quantitatively evaluated. For grounding wires with frequent abnormalities, targeted measures can be taken to reduce the possibility of failures, thereby solving the technical problems recorded in the background technology.

[0054] The step 1 includes the following contents:

[0055] Step 101, based on the Internet of Things, the operating status of each power equipment is obtained. When the non-operating state equipment requests to switch to the operating state, the tension and compression sensors installed at both ends of the equipment's power grounding wire are immediately started to detect the tension on both sides of the power grounding wire. When at least one of the tensions on both sides is less than a preset tension threshold, an abnormal grounding wire non-operating connection warning is issued.

[0056] The preset tension threshold is the average value of the tension data detected by all tension and compression sensors when the equipment starts to run.

[0057] Some equipment manufacturers provide dedicated software or platforms to monitor and manage the operating status of equipment. These software or platforms usually have an intuitive user interface and powerful functions to help you easily view and manage the operating status of the equipment.

[0058] Step 102: When the non-operating state device requests to switch to the operating state, the position chip installed at the grounding end of the power grounding wire is started to determine the installation position of the grounding end. After comparing it with the grounding pile position information stored in the Internet of Things system, the grounding pile to which the power grounding wire is connected is determined, and whether the installation position of the power grounding wire is accurate is judged, and an abnormal warning of non-operating connection of the grounding wire is issued.

[0059] It should be noted that the accuracy of the installation position of the power grounding wire is determined based on the allowable installation range of the grounding piles for each grounding wire stored in the Internet of Things. For example, power grounding wire No. 1 is allowed to be installed on grounding piles No. 1, 2 or 3. The position information comparison result shows that the grounding end is located at grounding pile No. 4. At this time, the grounding position of power grounding wire No. 1 is inaccurate, and an abnormal warning of non-operational connection of the grounding wire is issued.
