A remote station-entering licensing method for an unattended transformer station and an executing system

Abstract

The invention relates to a remote station-entering licensing method for an unattended transformer station and an executing system. A worker accesses a remote station-entering licensing WeChat public platform through a smartphone, fills in and submits a station-entering application, and sends the application to a centralized control station dispatching center. The centralized control station dispatching center checks the submitted station-entering application, confirms the identity of the worker to enter the station through WeChat video, and sends a licensing instruction to a server. The server generates a one-time password through a dynamic password generator, and sends the one-time password in a form of a WeChat massage to the smartphone of the worker to enter the station. The worker to enter the station inputs the one-time password into an intelligent door access system to open a corresponding door lock, enters a corresponding working zone and works. Through an internet mutual information technique, a remote-control management platform of the intelligent door access system of the unattended transformer station is built, remote licensing management of worker's entering or leaving the unattended transformer station is achieved, and station entering history information can be traced back and called at any time.

Description

technical field [0001] The invention relates to a management system for confirming a remote permit for unattended substation entry, in particular to a remote permit method for unattended substation entry and an execution system. Background technique [0002] Unattended substation is an advanced operation management mode of substation. It means that with the help of automation technology such as microcomputer telecontrol, the on-duty personnel can obtain relevant information in a remote place, and control and manage the equipment in the substation. There is no fixed operation and maintenance duty position in the unattended substation, and its operation management work is uniformly arranged and handled by the operation and maintenance operation station of the substation. [0003] With the development of power automation technology, the substations in the power system are basically unattended, and the operation and maintenance of substations adopts the centralized control cent...

AI Technical Summary

Problems solved by technology

[0004] At present, there are the following problems in the management methods of personnel entering and exiting unattended substations and on-site construction: 1) Allocating personnel according to the conventional operation mode, that is, sending personnel to unattended substations to open and close the gates, which will cause serious damage to personnel and vehicle resources Big waste; 2) At present, the number of personnel in the centralized control station is limited, and they are responsible for many businesses. Even if a special person is sent to the site to open and close the gate, it is often the mode that one person is responsible for multiple unattended substations, that is, the same person must be in charge of multiple substations. Traveling to multiple unattended substations for opening and closing operations will inevitably cause long-term waiting for the staff waiting to enter the station, which will directly affect work efficiency and greatly shorten the effective daily entry time; It is impossible to fully record the entry and exit of personnel in each unattended substation, and the post-event traceability function is poor; 4) The use of ordinary electric remote control unattended substation access control system cannot be combined with the substation security system to monitor the entry and exit of substation personnel in real time; 5) In the fire alarm , power outages and other emergencies or emergencies, it is impossible to timely or remotely control the gates of each area of ​​the unattended substation
