Substation tool management system and method based on three cards in one

Abstract

The invention discloses a three-card-in-one based transformer substation tool management system and method. The management system comprises a RFID electronic tag for identifying uniqueness of cards, a portable RFID reader for reading information of three types of RFID electronic tag identification cards of transformer substation workers, temporary ground wires and temporary ground points, a fixed RFID reader for reading electronic tag information in the identification cards of the temporary ground wires; a Zigbee router and coordinator for achieving information transfer of the portable RFID readers and a control center, and the background control center for state display of the temporary ground wires of a transformer substation and alarm information processing and storage. The three-card-in-one based transformer substation tool management system and method can be applied to building of an intelligent power grid, can improve the management level of power enterprises, meanwhile can effectively and completely eradicate missed ground wire taking, missed ground wire dismounting, switching-on with the ground wires and other malignant misoperation accidents, guarantees the power grid, equipment and personal safety to the most extent and has high application value.

Description

technical field [0001] The invention relates to a substation, in particular to a three-in-one substation tool management system and method. Background technique [0002] The status of personnel and some important safety tools in the substation has become a key factor affecting the reliable operation of power companies. Accidents often occur due to negligence of personnel at work and failure of some tools to be properly handled or used in a standardized manner. [0003] Taking the temporary grounding wire as an example, the temporary grounding wire is an important safety tool in the substation, and the installation of the temporary grounding wire is a safe and reliable protection barrier for the construction personnel in the power work site. The management of temporary grounding wires in substations is also an important link in the assessment, and scientific management also plays an important role in reducing accidents. At present, in the construction site of power engineeri...

Problems solved by technology

[0006]Some units and institutions have studied the use of IoT technology RFID for the management of various aspects of substations, such as substation staff equipped with RFID cards to achieve attendance, positioning, etc.; important equipment in substations Equipped with RFID cards for patrol inspection; important security tools are equipped with RFID cards for centralized management, but most of them are from a certain aspect, and cannot give a comprehensive solution

The three kinds of RFID cards are self-contained, each has its own management system, self-contained, and cannot share information

The disadvantage is that the system is repeatedly built, and the system equipment cannot be interconnected, resulting in unnecessary waste

[0007] Literature [Research on Temporary Grounding Wire Location Management System in Substation Based on RF ID Technology, Guo Fangying, Li Ying, Journal of Yunnan University for Nationalities (Natural Science Edition), November 2011] Studying the location of temporary grounding wire in substation can realize tool positioning Centralized management, positioning during the movement, and positioning of the destination, but only the approximate movement direction can be determined, and the location and status of the temporary ground wire cannot be accurately judged

[0008] Literature [Substation Temporary Grounding Wire Online Monitoring System, Huang Rui, Liang Qinglong, Zhang Baozhu, Huang Qiao, China High-tech Enterprises, Issue 33, 2010] Research on the use of electronic buttons Realize online monitoring of temporary grounding wires in substations, but there is no detailed description of the functional modules, device characteristics and parameter selection of the equipment, and different system modules and different devices have a great impact on the reading effect and system reliability

[0009] Literature [RFID-based intelligent tool cabinet management system, Jia Jingshan; Yin Shiyou; Lu Xiufeng; China Collective Economy, 2012, No. 25] research on the management scheme of RFID-based intelligent tool cabinets can only solve the internal work of power tool cabinets.
