Ground wire management system combining Zigbee technology and GPRS global positioning technology

Abstract

The invention relates to the technical field of power system monitoring and management. The invention further discloses a ground wire management system combining the Zigbee technology and the GPRS global positioning technology. The method comprises the following steps: S1, beginning; S2, an administrator formulating a system task in the background, S3, a worker receiving the task; S4, a hand-heldmachine identifying a ground wire RFID tag; selecting for delivery, S5, judging and selecting to enter S4 or S6; S6, carrying a grounding wire and a handset to an operation point; and S7, identifyingthe PFID of the connecting wire by using the hand-held machine, judging and selecting to enter S6 or S8; s8, starting a task; S9, hanging a ground wire; S10, performing maintenance operation; S11, removing the ground wire; S12, identifying the PFID of the connecting wire by using the hand-held machine, judging and selecting to enter S11 or S13; S13, ending the overhaul task; S14, the mobile phoneidentifying the PFID label of the connecting wire and selecting to put the PFID label in storage, S15, returning the handheld machine, and S16, ending the operation. According to the method, the problem of randomness in the execution process of the electric power safety regulation is solved, and an auxiliary supervision effect is achieved on the rigid execution force of safety regulations.

Description

technical field [0001] The invention relates to the technical field of power system monitoring and management, in particular to a grounding wire management system combining Zigbee technology and GPRS global positioning technology. Background technique [0002] Hanging the grounding wire is an indispensable work during the daily power outage maintenance of the catenary. It is a safety barrier to protect the construction personnel and can prevent the injury of the human body and the damage to the equipment caused by sudden calls. In addition to some basic requirements for the use of grounding wires, the specific use and management of grounding wires are not standardized enough, and there is still a lack of effective methods for the management and control of the storage and use of grounding wires.

[0002] Hanging the grounding wire is an indispensable work during the daily power outage maintenance of the catenary. It is a safety barrier to protect the construction personnel and can prevent the injury of the human body and the damage to the equipment caused by sudden calls. In addition to some basic requirements for the use of grounding wires, the specific use and management of grounding wires are not standardized enough, and there is still a lack of effective methods for the management and control of the storage and use of grounding wires. Due to the user's own safety awareness and self-awareness, there is a lack of effective technical means or measures

Major safety accidents such as casualties and serious equipment damage due to closing with a grounding wire have occurred frequently

[0003] According to statistics, 1 / 3 of the vicious misoperation accidents in the power system of power grid companies are caused by improper management or incorrect use of grounding wires.

The occurrence of these vicious accidents has brought life threats and property losses to staff, power equipment and users

According to the latest statistics of the power grid company, the vicious accident with grounding wire (grounding knife switch) closing ranks first in various misoperation accidents. One of the main reasons is that the management of safety equipment is not in place, and the registration of the use of power supply is not standardized. , Ledger updates are not timely, overdue failure to check and other situations have not been corrected in time

[0004] At present, during the entire maintenance operation, the connection and removal of the grounding wire is mostly communicated to the power supply dispatching center by telephone. Not only is the information form single, but the dispatcher cannot monitor the specific situation on the site, and the maintenance status depends to a large extent on the field work Personnel business proficiency and work responsibility, there is a possibility of omission and false positive

In addition, due to the long distance of the catenary section, when there are multiple operation groups overhauling at the same time and in different lines or sections, the number of hanging grounding wires is large and the dispersion is large, and it is difficult for dispatchers to judge the grounding through manual management. The position and state of the wire hook
